Class 234
SELECTIVE CUTTING (E.G., PUNCHING)
Class Definition:
This is a restricted class for the art of selective cutting
as defined below. For placement of a patent as an original in
this class, the claimed subject matter should meet the
minimum requirements of the class definition, and should not
extend beyond the general boundaries expressed in the Scope
of the Class, and Lines with Other Classes, below, which
concern mainly the combination of selective cutting with
other subject matter elsewhere classified.
SCOPE OF THE CLASS
The subject matter of Class 234 relates to means for, or
steps of, accomplishing the selection, or selection and
actuation, of one or a group of less than the total number of
cutting tool pairs from a given number of such tool pairs
which are constantly available for selection and actuation.
The great preponderance of patent disclosures of selective
cutting or punching also include means for, or methods of,
handling the work to be cut, or handling the product after
cutting. Many of such patents further disclose other
treatment of the work (e.g., printing, cutting to size, or
punching feed holes), or nonmanufacturing operations such as
computation of input data or verification of output data
which is related in some degree to the selection of tools.
The sole requirement for placement of a patent in Class 234
is that the means for or method of selection of tools be
included in the claimed subject matter. Patents which meet
this requirement may, however, be excluded from this class
because of the claimed inclusion of other subject matter for
which there are existing classes. Specific cases may be
decided as indicated in the following section, entitled LINES
WITH OTHER CLASSES AND WITHIN THIS CLASS.
In general, a patent which is restricted to means for, or
steps of, accomplishing the selection of one or more cutting
tools as outlined in the class definition, will be placed in
this class. Additionally claimed ancillary features such as
work holding, feeding, handling (e.g., counting or sorting),
detection of malfunction of machine, handling of pattern,
provision of specific data input arrangements and other
specific data input arrangements and other features, normally
to be found in a complete machine are also accommodated in
this class. Exclusion of a patent from Class 234, although
cutting tool selection is claimed, is generally based upon
additional recitation of (a) certain other treatment of the
work, (b) certain handling or treatment of the control data
or (c) other methods or devices which are elsewhere provided
for.
In general, a patent will not be originally placed in Class
234, if in addition to selective cutting means, it includes a
device which does not contribute to the ease or effectiveness
of operation of the cutting machine, or to a general
awareness (on the part of an attendant) of the conditions or
the results of its operation. The only exception to this
general exclusion rule is in the case of a patent to the
combination of selective with nonselective cutting means,
which will be placed originally in Class 234 (see
"Relationship to Other Classes, Including, per se, Cutting or
Other Treatment of Work--The Class of Cutting," below).
A number of terms currently used in the art have been
selected for definition in the Glossary of this class, and
will be identified by an asterisk (*) hereinafter.
The accompanying diagrams represent simple embodiments of the
various concepts treated. The elements most commonly found in
such mechanisms are uniformly designated in the diagrams as
follows:
W = workpiece* (typically a sheet or web)
P = pattern* (typically a marked or perforated sheet or web)
T = active cutting tool
D = die, or cooperating tool
H = tool-actuating hammer or press ram (reciprocable)
I = interposer*
K = key (representative of a keyboard)
Other elements necessary to the disclosures are designated,
where feasible, by terms commonly used in the art, and are
discussed in the individual diagram notes. Where only a
single tool of a selective cutting device is shown, it is to
be taken as representative of a plurality of such tools,
arranged in a row or as a bank (plurality of rows) in
proximity to a workpiece.
The placement of a patent as an original in this class will
hereinafter be referred to as "placement".
This class is restricted to:
(A) That kind of cutting device which is characterized by the
inclusion of a plurality of cutting tool pairs and an
actuating power train for each pair (one power train may be
common to all), so that power may be delivered to any or all
pairs for any cutting cycle, and wherein each tool pair
assembled in the machine is constantly available to be chosen
for cutting or noncutting in any desired number or
combination of pairs (from one to the total number available)
by:
(1) a pattern*,
(2) combinational-coding-means*, or
(3) means not a part of the tool-actuating power train and
which does not partake of all the movements of either tool of
the pair, which pattern or means conditions each pair so
chosen as to (a) enable, or (b) prevent, a cutting operation
thereby when its driving power train is actuated; and to:
(B) That type of procedure not elsewhere classified which
comprises (1) the step of selecting one or more cutting tool
pairs from a constantly available plurality of tool pairs, or
(2) the step of utilizing a selective cutting device as
defined above.
(1) Note. Placement in this class requires the claimed
recital of structure or method step set forth above.
(2) Note. Figures 1, 2 and 3 illustrate approximately the
minimum requirements for placement in this class, in the
three correspondingly numbered categories (1, 2, 3) of the
class definition. Each figure indicates a plurality of
independently movable tools and mechanism for effecting the
actuation of some or all of the tools, in any desired number
and arrangement (the number of keys, positions, tools, etc.,
would in actual practice be many times the limited number
shown in the diagrams).
Fig. 1 represents a pattern-controlled cutting device,
classifiable in subclass 77 of this schedule, wherein pattern
P acts similarly to a stencil, in that it blocks the
effectiveness of the nonselected tools T, while other tools
pass through holes in P and perforate the work W, upon
downward movement of hammer or tool-head H and consequent
compression of the springs.
Fig. 2 represents a single form of combinational-coding,
which may be termed "coded direct punching" (subclass 106).
Note that an individual tool may be actuated, at different
times, as a part of several distinct subgroups (e.g., to
perforate distinctive code symbols) in response to the
depression of different keys; this is in contrast to the
individual, independent key linkages indicated in the
nonselective device of Fig. 6, wherein a given tool responds
only to the depression of its own associated key. [figure]
[caption]Fig. 1. SELECTIVE CUTTING, PATTERN CONTROLLED.
(subclass 77) [figure] [caption]Fig. 2. SELECTIVE CUTTING,
CODED DIRECT ACTUATION (subclass 106) [figure] [caption]Fig.
3. SELECTIVE CUTTING, BY INTERPOSER(subclass 112)
Fig. 3 represents mechanism of the subclass 112 type, wherein
the gag or interposer* I is positioned by means (shown as a
manually slidable block on the machine frame) which is not a
part of the tool drive train and which does not move in
unison with the selected tool. (If the interposer I of Fig. 3
were manipulable directly, as by a knob fastened to its
extending rod and thus vertically reciprocable with the
tool-head H, the device would fail to meet the definition of
Class 234, and would instead be classifiable in Class 83,
Cutting, subclass 573, as a hand-actuated means to connect or
disconnect a tool and its continuously moving drive means).
Fig. 4 is presented further to illustrate the line between
this class and Class 83. The hand-manipulable interposer I
does not meet the limitations of part (3) of the class
definition, above, but it does qualify as combinational
-coding-means* under part (2) of the definition, and
specifically as a differential interposer (234- 98). This
line has been developed as a practical measure to distinguish
most of the (generally) production-type cutting machines of
Class 83. [figure] [caption]Fig. 4. SELECTIVE CUTTING, BY
CODED INTERPOSER. (subclass 98) (see (3) Note below) [figure]
[caption]Fig. 5. NONSELECTIVE CUTTING, Class 83 type. (see
(4) Note below) [figure] [caption]Fig. 6. NONSELECTIVE
CUTTING, Class 83 type.
From the (generally) data-handling selective cutting machines
of Class 234. The availability of two or more sub-groups of
tools in Fig. 4 makes the device selective under the class
definition.
(3) Note. Specifically excluded from this class is a patent
to a cutting method or apparatus which concerns the
production of distinctive cutting operations solely by
varying the position, the cutting stroke, or the time of
actuation of a single tool (or a group of tools driven always
as a unit). Fig. 5 represents such a device having a single
tool, adjustable in position on a reciprocable ram; there is
no "selection" from among a number of tools, but a mere
adjustment of one tool. Also excluded is a patent to
apparatus having a turret of tools, wherein the positioning
of one tool for a cutting operation necessitates the movement
of the other tools away from their effective positions.
(4) Note. Further excluded is a patent to cutting apparatus
in which the distinctive cutting operations are effected by
direct (manual or power) actuation of one or more
independently drivable tools at the will of an operative.
Fig. 6 illustrates the excluded combination of tools, each
driven by an independent key linkage, which is classifiable
in Class 83, subclass 633, as a reciprocable tool driven by a
fixed-axis lever. Fig. 7 illustrates the excluded combination
of tools which lack a common power train or individual power
trains for all tools; the single driving cam, shiftable along
the rod, places this combination in Class 83, subclass 549.
(see (4) Note in section II) [figure] [caption]Fig. 7.
NONSELECTIVE CUTTING, Class 83 type.
LINES WITH OTHER CLASSES AND WITHIN THIS CLASS
A. THE CLASS OF CUTTING IMPLEMENTS, CLASS 30.
A patent to a selective cutting or punching device will not
be barred from original placement in Class 234 by reason of
the fact that the device is intended to be hand-held and/or
hand-actuated and/or work-supported.
B. THE CLASS OF SEVERING BY TEARING OR BREAKING, CLASS 225.
A patent to the combination of selective cutting means with
means to sever (the work or product) by tearing or breaking
will be placed originally in Class 234. The combination of
tearing or breaking means with other (i.e., nonselective)
severing means is found in Class 225, subclass 7.
C. THE CLASS OF CUTTING, CLASS 83.
Class 83 is an elemental or basic class. That is, its subject
matter is restricted (so far as possible) to means for, or
steps of, accomplishing the following functions: cutting
something (the "work"); or cutting and handling the work to
be cut; or cutting and handling the product of the cutting
operation. Class 234 being superior to Class 83, a patent for
the combination of a cutting device or method classifiable,
per se, in Class 83 and a selective cutting device or method
will be placed originally in Class 234. For a complete
statement of the relationship between Class 83 and Class 234,
see the class definition of Class 83.
D. THE CLASS OF PRINTING, CLASS 101.
Generally speaking, the recording or alphabetic or numeric
characters by cutting is proper subject matter for Class 101,
Printing. More particularly, individual cases of selective
cutting may be tested for aptness to Class 101 by reference
to the following statements:
(1) If in addition to a selective cutting machine or process
of Class 234 there is claimed a means or step peculiar to
Class 101 (e.g., the application of ink to the cutting tool
to additionally outline or mark an aperture made by the
punch, or the printing or embossing of characters or designs
by means other than the cutting tools), the patent directed
to such combination will be placed in Class 101.
(2) A patent directed to the selective cutting of a letter,
number or aesthetic design will be placed in Class 101,
subclass 18.
(1) Note. The term "design" in this instance denotes a
picture, a decorative or artistic arrangement of perforations
or cut edges, or direct intelligence-bearing perforations or
cuts; as distinguished from coded symbols. In case of doubt
as to whether a patent discloses direct intelligence-bearing
or codes symbols, placement will be in this class (234).
(3) A patent directed to the selective embossing of a letter,
coded symbol, character or design will be placed in Class
101, subclass 18. (Such a patent would a priori be excluded
from Class 234 on the ground that it is not concerned with
cutting).
E. THE CLASS OF TYPEWRITING MACHINES, CLASS 400.
Patents for key-operated machines for the simultaneous
composition and production of printed matter generally, are
placed in Class 400, Typewriting Machines. The combination of
typing and selective punching will in all cases be placed in
Class 400, subject to the following qualifying statements:
(1) If only so much typing structure is claimed as is
necessary to constitute a completely operative selective
punching machine, the patent will be placed originally in
Class 234 on the ground that the combination with typing is
not positively claimed. (e.g., the recitation of typewriter
keys, key levers, type bars, and means responsive to
actuation of the type bars to select cutting tools is not
considered sufficient for placement of the patent in Class
400 unless the structure claimed is sufficient to effect
actual character production on the work; nor is the further
recitation of escapement means and a movable paper carriage,
if it appears that the carriage exerts a control on some
function of the cutting mechanism, such as the feed of a card
relative to the cutting tool station).
(2) The nominal recitation of a typewriter in combination
with specific selective punching machine is not considered
sufficient for placement of a patent to the combination in
Class 400.
(3) A patent directed to the production of printed matter
through the agency of a paper tape perforated under control
of a keyboard will be placed in Class 400.
F. THE CLASS OF RECORDERS, CLASS 346.
A process or apparatus which would be otherwise proper for
Class 346, Recorders, will not be removed from the scope of
that class merely by virtue of the fact that the recording,
as claimed, is accomplished by a selective cutting mechanism
or method step.
RELATIONSHIP TO OTHER CLASSES INCLUDING, PER SE, HANDLING OR
TREATMENT OF DATA
A. THE CLASS OF TELEGRAPHY, CLASS 178.
A process or apparatus which would be otherwise proper for
Class 178, Telegraphy, will not be removed from the scope of
that class merely by virtue of the fact that the recording of
the transmitted message, as claimed, is accomplished by a
selective cutting mechanism or method step.
In general, a recording or "printing" telegraph of Class 178
is distinguished from a selective punching machine of Class
234 by comprising one or a limited number of electrical input
channels through which messages, unlimited with respect to
the variety or extent of information they are adapted to
convey, are transmitted from a distant point, the elements of
the messages being selected according to a prearranged code.
The claimed inclusion of a distant transmitter, or of means
to decode electrical impulses originating at a distant point
and conveyed over a relatively small number of channels,
exemplifies the type of subject matter which would be placed
in Class 178 rather than in Class 234, even though the
recording may be accomplished by selective punching
mechanism.
B. THE CLASS OF REGISTERS, CLASS 235.
There are generally three types of disclosure which contain
subject matter common to Class 235, Registers, and Class 234,
as follows:
(1) A patent directed to a calculating machine combined with
selective mechanism for punching the data set up or the
results, or both, which would be placed in Class 235.
(2) A patent directed to a selective punching machine
combined with a register to ascertain the number of machine
operations or number of workpieces treated, which would be
placed in Class 234.
(3) A patent for a keyboard controlled selective punching
machine combined with a register for totalizing incremental
quantities (e.g., type-widths and interword-spaces) related
to the key-selected data, and means to indicate the approach
of the total toward a predetermined quantity (e.g., the
required length of a completed line of type composed
according to the key-selected data), which would be placed in
Class 234, subclass 4.
RELATIONSHIP TO OTHER MATERIAL HANDLING CLASSES
This class (234) receives original patents claiming
significantly both a selective cutting or punching device and
(a) means to separate or assort portions of the product
resulting from the cutting operation, or (b) means to move or
feed work, or (c) means to hold or move a pattern* or copy*.
For the placing of patents which refer more broadly to a
cutting tool or operation in combination with work or product
handling, see the class definition of Class 83, Cutting.
GLOSSARY:
ACTUATION

in which position portions of said element engage tools of a
plurality of tool pairs, thereby completing a drive train for
the subsequent effective transmission of actuating power to
the corresponding tool pairs. (Cf. Interposer).
CODED-SELECTOR-MEANS
An element which is movable to and from an effective position
in which it determines the selection of a plurality of tool
pairs by other mechanism. (Note. This element differs from a

auxiliary-operations*. (Cf. input-means*).
INPUT-MEANS
An instrumentality which is effective to exert control over
the operation of tool-selecting mechanism and/or mechanism to
perform an auxiliary-operation*, in response to the
application of an input-impulse* to such input-means, (e.g.,
a keyboard, a dial, a pattern-sensing unit, etc.)
INTERPOSER
An element which is movable to and from two or more
positions, in one or more of which positions it is effective
to condition a tool pair for actuation by its engagement with

The transfer of data to a storage* device.
READ-OUT (n.)
The transfer of data from a storage device or other means, to
tool selection mechanism.
SELECTION

This subclass is indented under the class definition. A
procedure which comprises the step of selecting one or more
cutting tools or utilizing a selective cutting device.
Subclass:
2
This subclass is indented under subclass 1. Procedure which
comprises the step of detecting the indicia or the
characteristics of a pattern.
Subclass:
3
This subclass is indented under subclass 2. Procedure which
comprises the step of varying (1) the characteristics of a
pattern or (2) the response of a machine to pattern
characteristics.
Subclass:
4
This subclass is indented under the class definition. Device
comprising means to cut character and space-representing code
perforations successively in a strip of material and,
substantially simultaneously, to cut other perforations
representative of incremental quantities related to said
characters (e.g., their widths when set up in type), and
further comprising means to totalize said quantities (by
means of a counter or measuring unit) and means to indicate
the approach of said total toward a predetermined quantity
(i.e., the length of a completed line of type).
(1) Note. A patent directed to a device for punching a
typos:graphical-machine- controlling strip will not be placed
in this or the indented subclasses unless all or a
significant portion of a justification-space counter and/or
indicator or associated structure pertaining to justification
is claimed. Other features, such as repeat key systems, may
be found in appropriate subclasses herebelow, in devices
which could conceivably be utilized as composing machines.
(2) Note. Some patents have been cross-referenced to this
subclass on the basis of disclosed features deemed important
to selective typos:graphical punching machines even though
the disclosures are not clearly of the selective type.
SEE OR SEARCH THIS CLASS, SUBCLASS:
125 for a "repeat key" mechanism on a composing machine or
other selective punching device.
SEE OR SEARCH CLASS:
400, Typewriting Machines, 1 and 77+ for a "composing
machine" which prints code symbols on a tape, and comprises
some justification structure.
Subclass:
5
This subclass is indented under subclass 4. Device which
includes a portion that can be removed and replaced by
another assembly having characteristics related to a
different size or style of type which alters the selection of
tools in response to a given input impulse.
(1) Note. Usual examples are interchangeable keyboards or
permutation-bar units, usable to adapt a single machine for
composing matter in different fonts or type styles. Provision
is thus made for suitably altering the selection of punches
and the drive to the justification counter and/or indicator.
SEE OR SEARCH THIS CLASS, SUBCLASS:
14 for programmed means to alter a code.
69 for code production or conversion means associated with a
pattern-controlled punching device.
96 for means in a selective cutting device for changing a
code or facilitating change thereof.
Subclass:
6
This subclass is indented under subclass 4. Device which
includes a modification adapted to simplify or reduce the
number of operations required to effect the cancellation of a
portion of the series of perforations made in previous cycles
of the machine.
(1) Note. Such a device usually operates in two general
steps: (1) to restore the justification counter and indicator
to the conditions they occupied prior to the punching of the
canceled subject matter; and (2) to overpunch the matter to
be canceled, or to insert an error symbol in appropriate
position to be sensed by the type-casting machine for which
the tape is intended to be used.
Subclass:
7
This subclass is indented under subclass 4. Device including
means effective to provide subtotalization of said
incremental quantities at a plurality of predetermined points
in the composed line, or means to effect alteration in the
length of line to be composed.
(1) Note. A device of this subclass type facilitates the
composition of printed lines of different lengths, and the
composition of tubular matter (i.e., in vertical columns).
Subclass:
8
This subclass is indented under subclass 4. Device including
means for cutting in said strip one or more perforations
which represent the widths of interword-spaces so selected at
the completion of each line as to cause the completed line
(when set in type by a machine not claimed here) to be of a
predetermined length.
(1) Note. Actuation of the selected tools to produce
justification indicia in the control strip may be effected
manually (by special key or incidental to another manual
operation such as line feed), or may be automatic.
Subclass:
9
This subclass is indented under subclass 8. Device including
means responsive to justification conditions as determined by
a justification counter or indicator to control the
conditioning of tools without the intervention of an
operative.
Subclass:
10
This subclass is indented under subclass 9. Device,
including means to insert the justification symbol or symbols
at the beginning of a line or in interword-spaces.
(1) Note. The more conventional system is to insert
justification symbols at the end of the line, which usually
requires later that the control tape be fed backward into the
typesetting machine; for which see subclasses 8 and 9.
Subclass:
11
This subclass is indented under subclass 4. Device including
means to advance the counter or measuring unit.
(1) Note. Also included are arrangements for altering or
adjusting (rather than exchanging) the counter drive to
accommodate different type fonts or to space the letters of
words.
SEE OR SEARCH THIS CLASS, SUBCLASS:
4 for a machine including a mere justification indicator
(i.e., which does not totalize or compute justification
data).
5 for a machine with exchangeable parts to accommodate
different fonts.
7 for a machine with provision for altering the counter or
measuring unit drive incidental to tabulating or line length
adjustment.
Subclass:
12
This subclass is indented under subclass 11. Device wherein
the counter consists of a toothed wheel driven through
assigned increments of rotation by one or more toothed
racks.
(1) Note. Counters of this type, termed "unit-wheel", are in
wide use (see Patent No. 663, 996, granted December 18, 1900,
to T. Lanston).
Subclass:
13
This subclass is indented under the class definition. Device
which performs a plurality of operations in sequence and
which comprises means effective at a predetermined point in
said sequence to modify or render effective or ineffective
certain machine controlling impulses other than those
impulses which directly control the selection of tools.
(1) Note. For example, the changeover from one code system
to another, and the shift of control from one input source to
another, are merely preparatory to subsequent tool selection
operations, hence they are regarded as
"auxiliary-operations", rather than as constituting direct
control of tool selection. The term auxiliary-operation*
implies any action, operation, or change of condition of a
device or part thereof, other than the actual selection of
tools for cutting or noncutting action in any cycle of tool
actuation. For further examples of auxiliary-operations, see
Definitions of Terms.
(2) Note. The term "programmed" implies that any of the
actions or changes of conditions referred to in (1) Note,
above is the result of a prearranged timing schedule and thus
occurs at one or more fixed points in the timed sequence of a
machine operation, as against any random time dependent upon
the receipt of signals from an external source (e.g.,
actuation of a keyboard by an operative), or upon the
occurrence of a condition which is not definitely related to
any particular cycle of operation of the machine (e.g., the
occurrence of a misfeed overload, or other malfunction).
(3) Note. Programming may be effected by sensing a card,
tape, or other medium while at rest or while progressing
through the machine. Such a card or tape is distinguishable
from a "pattern" card or tape by the fact that a programming
medium controls auxiliary-operations of the machine. If it
further contains tool-selection-controlling data, it is a
combined program-pattern element, and the programming feature
would prevail in the original classification of a patent to
the combination.
(4) Note. Certain conventional features commonly found in
card punches, namely: the so-called "last-column contact"
circuits, or automatic card-feed and card-eject devices in
general, are not deemed as of sufficient interest in this
class to warrant cross-referencing into subclass 13 unless
included in the claimed invention.
Subclass:
14
Device under cubclass 13 wherein the program means modifies a
code* of substitutes one code for another.
(1) Note. The program means found in this subclass does not
select tools directly, but effects a change in the system of
tool selection (i.e., a change of code, such for example as
the substitution, at certain points only in the sequence of
operations, of a "space" symbol for a "zero" in response to a
"zero" impulse).
(2) Note. The automatic insertion of zeros or suppression of
zeros while punching numerical data is an example of "change
of code". This auxiliary-operation, if arranged to occur only
at predetermined points in the sequence of machine cycles, is
said to be "programmed"; if, however, it takes place whenever
a certain condition or combination of conditions should arise
(e.g., upon detection of an initial zero in numerical data
received from a keyboard or a pattern-reader) it is a
randomly effected change of code, classifiable in subclasses
22+.
SEE OR SEARCH THIS CLASS, SUBCLASS:
24 for means to automatically insert or to suppress the
punching of a zero symbol, under the control of randomly
effective operating conditions.
96 for means to change or facilitate change of code, in a
selective cutting device.
Subclass:
15
This subclass is indented under subclass 13. Device wherein
additional means is provided for conditioning the device to
follow one of a plurality of distinct predetermined sequences
of operations.
Subclass:
16
This subclass is indented under subclass 13. Device wherein
the program means terminates the transmission of
machine-controlling impulses from one specified portion of
the device and effects initiation of transmission of such
impulses from another specified portion of the device.
(1) Note. For original placement in this subclass, a patent
must claim means to connect a second input means, as well as
means to disconnect a first input means. The mere addition of
an overriding control of a single input means (e.g., the
operation of keys by a pattern-responsive mechanism at
certain times) is found in subclass 20.
Subclass:
17
This subclass is indented under subclass 16. Device wherein
the two specified portions of the device differ in both
structure and function.
(1) Note. Such portions may be, for example, a keyboard and
a pattern- senser or data storage device.
Subclass:
18
This subclass is indented under subclass 13. Device wherein
said program means effects a predetermined change in the
location of a cutting tool pair with respect to work and/or
in the location of the effective portion of a pattern-sensing
mechanism with respect to a pattern.
(1) Note. Patents in this subclass disclose means for
altering, at predetermined times, the relative recorded
positions of data being read from a pattern or storage means,
or being supplied from a keyboard or other input means.

also arrangements for permitting "multiple punching" in given
columns.

This subclass is indented under subclass 13. Device, wherein
the program means effects initiation or termination of
transmission of machine-controlling impulses from a specified
portion of the device.
(1) Note. Included here is the conventional "column cutout
bar" control which starts and stops duplicating operations at
predetermined card columns, permitting an operative to insert
manually keyed data in certain fields of a card.
Subclass:
21
This subclass is indented under subclass 13. Device provided
with means to bring one or more parts to a halt after the
completion of a fixed plurality of cycles of operation of the
device or of any portion thereof which is periodically
actuated.
(1) Note. This subclass does not include "repeat key"
mechanisms, for their actuation is manually initiated at
random times (i.e., at the will of an operative), for which
see the Search This Class, Subclass note below.
SEE OR SEARCH THIS CLASS, SUBCLASS:
51 for means to effect unicyclic tool actuation.
125 for repeat key mechanism, and see (1) Note, above.
Subclass:
22
This subclass is indented under the class definition. Device
provided with means for initiating, modifying, or terminating
the functional effect of some portion of the device other
than or in addition to the tool selecting mechanism, per se;
such control-imposing means acting in response to a signal or
impulse which cannot be predicted to occur during any
particular one of a number of recurring cycles of operation
(either of the machine as a whole, of a tool, or of any part
of the machine which has a cyclic law of operation).
(1) Note. Such means may comprise, for example, a device
effective to stop a selective cutting machine upon the
detection of a jam in the work feed mechanism, or to start
such a machine upon the presentation thereto of a pattern or
a workpiece, or to temporarily suspend tool actuation during
the passage of a particularly identified card through the
punching station or to cause automatic change of code under
certain operating conditions which occur at random times.
(2) Note. The claimed combination of pattern-sensing means
and tool-selecting means controlled thereby is found in
subclass 59, below. The selection of tools being in the main
characteristic of Class 234, it is not included in the
meaning of the term
(3) Note. In general, an operation which is specifically
voluntarily initiated, as by the depression of a claimed
special key on a keyboard, is not regarded as a random
operation within the meaning of this subclass definition. The
term "random" is applied in Class 234 to operations which
occur in response to given conditions or otherwise without
voluntary initiation by an operative. Means for performing a
given operation at the will of an operative or attendent will
generally be found in a subclass relating generally to means
for performing the pertinent operation, or in the keyboard
subclasses 123+.
SEE OR SEARCH THIS CLASS, SUBCLASS:
13 for programmed control of auxiliary-operation.

workfeed, repeat operations, column skipping, etc.).
Subclass:
23
This subclass is indented under subclass 22. Device provided
with additional means which is differentially responsive, to
two or more diverse bits of data which control the selection
of tools in the device, in such manner that a certain time
sequence of transmission of such bits makes said additional
means effective to transmit said signal or impulse to the
control-imposing means.
(1) Note. For example, a device in this subclass may effect
an automatic change of code, sometimes involving the punching
of "letters shift" or "figures shift" symbols at appropriate
locations in an output tape. The control- imposing means does
not select tools, but establishes or selects the system by
which tool selections are governed, during the existence of a
given operating condition.
SEE OR SEARCH THIS CLASS, SUBCLASS:
14 for means to perform a similar operation under programmed
control.
Subclass:
24
This subclass is indented under subclass 23. Device wherein
the additional means is differentially responsive to the
occurrence of a zero or a significant digit, and the
control-imposing means is capable of determining the
actuation or nonactuation of a tool or group of tools (which
has been selected by other means) to represent a zero
symbol.
(1) Note. The systematic substitution of a "zero" for a
space or other character, or substitution of a "space" for a
zero, at every occurrence, is simply a change of code. A
device having this function would be classified in one of the
appropriate subclasses relating to "coded" punching (see the
Search This Class, Subclass note below, for example).

This subclass is indented under subclass 22. Device provided
with additional means which is capable of sensing data or a
characteristic of a pattern* or workpiece*and initiating the
control-imposing signal or impulse in response to the sensing
of a predetermined symbol or characteristic.

said control-imposing means governs the transfer or
nontransfer of data from a pattern to a workpiece, the device
being further provided with a comparator effective to compare
data sensed by such additional means with other data stored
in the device or concurrently sensed from a pattern or
workpiece, and means to initiate the control-imposing signal
or impulse under a given condition of correspondence or
noncorrespondence of said compared data.
(1) Note. The auxiliary-operation controlled in this case is
the tool actuation (as distinct from tool selection) or the
transmission of selection impulses to the tool-selection
means.

said control-imposing means regulates the progressive
movement of a pattern with respect to pattern-sensing means.
Subclass:
30
This subclass is indented under subclass 22. Device wherein
said control-imposing means operates by bringing any or all
of the moving parts of the device to a halt or by terminating
an auxiliary-operation (e.g., tool actuation).
(1) Note. It is not a bar to original placement of a patent
in this subclass, that the claimed power train disrupting,
breaking, or other "stopping" means may be activated at a
time when the part to be halted is, purely adventitiously, at
a standstill due to its normal cyclic operation.
(2) Note. Patents in this subclass (30) may claim the
combination, in a selective cutting device, of stopping means
initiated by sensing the absence of work or pattern, or
sensing misplaced or defective work, etc., wherein the
occurrence of such condition, as disclosed, is not by reason
of defect or malfunction of the device, for which latter
condition, see subclass indented hereunder.
SEE OR SEARCH THIS CLASS, SUBCLASS:
22 for random control which may include, but is not limited
to stopping (e.g., means to start a machine upon presentation
of work or pattern which may be combined with means to stop
the machine upon withdrawal of work or pattern).
Subclass:
32
This subclass is indented under subclass 30. Device provided
with additional means responsive to a failure of a machine
part, or to an abnormal position or functioning thereof, to
initiate said signal or impulse.
(1) Note. Random stopping means which responds to absence or
abnormal position of a pattern or workpiece, irrespective of
the cause for such condition, will be found in subclass 30.
Subclass:
33
This subclass is indented under subclass 32. Device provided
with means which responds to tool actuation or senses
characteristics of the workpiece subsequent to tool actuation
and which initiates said signal or impulse in response to (1)
a failure of the device to follow a predetermined type of
tool operation, or (2) the correct completion of such
operation, which signal or impulse governs the continuance of
operation of the machine or of a part thereof.
(1) Note. For example, the means may be used to check the
presence of a punched hole in each column of a card before it
leaves a card punch machine.
(2) Note. A check on tool actuation includes, but does not
require, verification of the correctness of the punching
operations, for which see subclass 34, indented hereunder.
(3) Note. The term "stopping" in subclasses 30+ is broadly
construed to embrace a change in the mode of operation of the
device which involves the cessation of a particular function
even though parts concerned may still have motion.
Subclass:
34
This subclass is indented under subclass 33. Device in which
the signal- or impulse-generating means responds to a
disparity between the selection control impulses received by
the device and the consequent operations performed by the
device.
Subclass:
35
This subclass is indented under the class definition. Device
including input-means* which means affects both mechanism for
selective cutting as well as mechanism for applying embossed
or visibly tinted character-representing symbols to a
workpiece.
(1) Note. The printing and cutting operations may be applied
to the same or to different workpieces, and either
simultaneously or nonsimultaneously.
(2) Note. The claimed inclusion of any specific element of a
printing device, which element is not a necessary part of the
control or actuating mechanism of the selective cutting
device, is a bar to placement of the patent in this class.
For example, a patent to a combined "typewriter-punch"
wherein the typewriter key levers actuate punch-selection
mechanisms and the paper-carriage movement controls feed of a
card to the punching station, would be placed as an original
in Class 400, Typewriting Machines, if the claims referred
also to "types", or ribbon feed or line-feed mechanism, etc.

(1) Note. A patent to a selective punching device comprising
a manually movable stylus to control tool selection, and a
holder for a drawing or design to be traced by such stylus,
will be placed as an original in this subclass.
(2) Note. The terms copy* and "data source" do not imply
direct control of a machine therefrom, as in the case of a
pattern* or a "program device", but merely afford information
for the guidance of an operative or attendant, who in turn
controls the selection of tools.

This subclass is indented under the class definition. Device
which comprises two or more distinct arrays of selectively
controlled tools, or one array composed of distinct groups of
tools controlled by separate tool selection mechanism.
(1) Note. A device in this subclass may consist of a
plurality of virtually complete selective cutting machines
interconnected to some degree as by control means or common
drive means; or it may be in effect one cutting machine
provided with distinct arrays of tools and conforming with
the above definition.
(2) Note. The plural tool fields need not be spaced apart
physically: tools of the several fields may be adjacent (or
even intermingled) if there are distinct actuating means
and/or distinct selecting means for each field.
(3) Note. The conventional Powers-type card punch, having a
full bank of punch elements connectable column-by-column to a
single input means (keyboard and pin-setting carriage) does
not constitute a plural tool field selective punching device,
for the selection means, as well as the actuating means is
common to all columns of punches.
(4) Note. The addition of a second input means, such as a
serial numbering attachment, to a selective punching device
to control the punching in certain columns of a card will not
of itself effect patent placement in this subclass.

transmitted from an input-means* and to register and retain a
distinctive record thereof, after cessation thereof and
further means effective to read said record and to transmit a
corresponding control impulse to the tool selection means.
(1) Note. For inclusion in this or an indented subclass, a
patent must claim means which is selectively conditioned by a
signal or impulse transmitted by an input-means and which, at
some time thereafter, takes part in the generation or
transmission of another signal or impulse, representative of
the first, as determined by such selective conditioning.
(2) Note. To constitute data storage there must be retention
of distinctive information after removal of the input-impulse
(e.g., retraction of the depressed key) and before the
corresponding tool selection has been effected.
(3) Note. Storage may be effected by a recording mechanism,
(such as a tape punch), and a sensing means, so arranged that
data stored in the tape is later utilized to control tool
selection.
(4) Note. Fig. 8 illustrates the essentials of one type of
storage system. Depression of any key K energizes an
associated storage relay SR, which remains energized over a
circuit including its hold contacts a. When at some later
time, read-out contacts R-O are closed, circuits are
completed through contacts b of all energized relays, thus
energizing the associated magnets M and positioning
interposers I in readiness to actuate tools T upon the next
stroke of ram H. (In practice, relays SR would ordinarily be

This subclass is indented under subclass 59. Device which
comprises means responsive to the detection of a portion of
the device which portion has periodic motion, for selection
or varying the existing selection of tools.

said sensing means is caused to act with respect to a
workpiece* presented to the device for cutting by the tools
thereof. [figure] [caption]Fig. 11 Reperforated or
overpunched card. (subclass 63)
(1) Note. Within the scope of this subclass, the work may be
sensed prior to, during, or after its treatment.
(2) Note. Fig. 11 illustrates an application of the
mechanism of this subclass; a marked or punched card is
sensed and punched, to change marks to holes, or to convert
small holes to large ones, etc.

said sensing means is so arranged as to act upon a product
which has been previously subjected to cutting operations in
the device.
(1) Note. In the card punching art, the use of a
newly-processed card as a pattern for the following card is
commonly referred to as "gang-punching".
Subclass:
65
This subclass is indented under subclass 59. Device further
provided with input-means* in addition to said sensing means,
and means for enabling effective transmission of signals or
impulses from both said input-means during the same operating
cycle of the machine.
(1) Note. The additional input-means may also be
pattern-sensing mechanisms thus affording tool selection
control by two or more patterns.
(2) Note. Disclosures in this subclass include "edited" or
supervised selective punching, wherein a pattern-sensing
mechanism imposes restrictions on the selection of punches by
other means (e.g., keyboard).

Subclass:
66
This subclass is indented under subclass 59. Device which
includes a plurality of sensing means arranged to coact
simultaneously with all significant points of a pattern
field, and further including means effective to establish, in
sequence, a plurality of signal or impulse transmission
channels, each extending from a group of such sensing means
to the tool selecting means or to a portion thereof.
(1) Note. Fig. 15 illustrates typical mechanism found in a
device of this subclass. A pattern card is clamped in a
sensing unit which may comprise a full bank of spring-biased
sensing pins. Movement of the sensing unit and pattern past a
microswitch causes successive positionings of interposer I
corresponding to those sensing pins which have entered holes
in the pattern and are thus misaligned with the others.
Storage* is not involved here, for the input-impulses* are
retained (by the positioned sensing pins) until tool
selection has been effected. [figure] [caption]Fig. 15.
FULL-BANK SENSING, READ-OUT STEP-BY-STEP. (subclass 66)
Subclass:
67
This subclass is indented under subclass 59. Device provided
with means to effect significant alteration, in any one
cutting cycle, of the relative positions of the selected
cutting tool pairs with respect to the positions of
corresponding control indicia or characteristics in the
pattern.
(1) Note. The general effect produced by a device of this
type is to make a product which has cut or punched portions,
not all of which correspond in spatial position or
arrangement to their related pattern indicia.
(2) Note. Included here are some patents which claim such
arrangements of tools, control means, and/or pattern sensers
as to enable the use of smaller, cheaper, or more simplified
mechanisms than could be achieved with the use of "facsimile"
patterns.
(3) Note. Included in this and indented subclasses are, for
example, disclosures of means to effect one or more of the
following functions: to produce a combinational-code*, to
decode such a code into a single cutting operation, to
convert from one code to another, to produce a complementary
or "inverse" duplicate of a field of perforations, to
reproduce only selected fields of a pattern, or to shift the
relative positions of data being reproduced.

Subclass:
68
This subclass is indented under subclass 67. Device wherein
the altering means is effective to cause nonselection of a
cutting tool in response to sensing of a pattern indicium,
and to cause selection of a cutting tool when no such
indicium is sensed. [figure] [caption]Fig. 12 Inverse or
complemental punching from pattern of Fig. 9 (subclass 68)
(1) Note. A device of this subclass produces the "inverse"
or "physical complement" of the pattern field.
(2) Note. A device which produces the "code complement" of a
code symbol is not classifiable here but in subclass 69 as an
instance of code conversion, rather than inversion. The code
complement of a code symbol may bear no physical resemblance
to the "inverse" of the group of perforations which
constitute the symbol.
(3) Note. Fig. 12 illustrates a card which has been punched
with the inverse or complement of the indicia from the
pattern card of Fig. 9.
Subclass:
69
This subclass is indented under subclass 67. Device wherein
the altering means effects a change from a code* exhibited by
the pattern to a different code cut into the workpiece.
[figure] [caption]Fig. 13 With code conversion. (subclass
69)
(1) Note. Any device of this type effects "code conversion".
In some instances it would appear instead that a code is
being "generated" (as when alphabetical or numerical
characters are sensed to control the selection of linearly
arranged tools), but the operation is always basically the
same, i.e., the transfer or intelligence from one record to
another, with a systematic change from one set of arbitrary
symbols to another.
(2) Note. Basic mechanisms of the so-called "tape-to-card"
or "card-to-tape" record-controlled duplicating machines are
found here, for different codes are ordinarily employed in
the two record media.
(3) Note. A device which, upon reading the symbol of a digit
in a pattern, effects the punching of the symbol of the "tens
complement" or "nines complement" of that digit, may be found
in this subclass. See (2) Note under subclass 68.
(4) Note. Fig. 13 illustrates code conversion. The data from
the pattern of Fig. 9 has been reproduced, but the
four-element code symbols appearing in the pattern have been
altered to conform to a different code (in this example,
another four-element code). In practice, the change may be
from one statistical system to another, or from Morse to
Cable Code, five-channel tape code to seven-channel code,
etc.

said altering means is systematically effective (a) to cause
the selection of two or more tools in response to the sensing
of one pattern indicium, or (2) to cause the selection of one
tool in response to the sensing of two or more pattern
indicia.
(1) Note. A device of this subclass converts a
combinational-code* to or from a one-hole-code*.
Subclass:
71
This subclass is indented under subclass 67. Device in which
the alteration is brought about by means effective to
interpose variable time delays between the pattern-sensing
and tool-actuating functions in successive cycles.
(1) Note. The subject matter of this subclass (71) and the
following subclass (72) concerns generally the relocation (or
suppression) of data from certain portions of a pattern,
while preceding subclasses 68 and 69 deal generally with
modification of the significance of the data itself (e.g.,
the relocation of punched holes in a column).
(2) Note. A typical device of this subclass effects the
"standardization" of a perforated music roll such that all
perforations in the reproduced roll have locations and
lengths expressable in whole multiples of a unit space.
Subclass:
72
This subclass is indented under subclass 67. Device wherein
the alteration is brought about by varying the effect of the
sensing means (of the device of subclass 59) with respect to
a predetermined portion of a pattern, as follows: (1)
disablement of the sensing means, (2) interruption of the
transmission of tool-selecting control impulses from the
sensing means to corresponding tool-selecting means, or (3)
establishment of an alternate or an additional channel for
transmission of such control impulses to other tool-selecting
means.
(1) Note. See (1) Note under subclass 71, above.
(2) Note. The functions found in machines of this type
include the "skipping" of a pattern-field* or a zone of a
workpiece (i.e., omission to sense and/or to punch the field
or zone in question), and the "transposition" or "shift" of
fields (i.e., changing their effective position, as by
sensing two such fields in altered sequence.
(3) Note. Fig. 14 illustrates shift of data fields, without
alteration of the significance of the data. Columns A-E of
the pattern (Fig. 9) now appear in the order C, D, E, A, and
B respectively, which may be appropriate to a different form
of business record. [figure] [caption]Fig. 14 With shift

the sensing means is capable of generating any one of a
plurality of signals or impulses distinct in degree or
character, in response to different sizes or kinds of pattern
indicia or characteristics being sensed, and including means
to select distinct tools or combinations of tools
corresponding to such distinct signals or impulses.
(1) Note. For example, the pattern senser may distinguish
between larger and smaller pattern holes to cause the
selection of different tools or combination of tools.
Subclass:
75
This subclass is indented under subclass 59. Device
comprising means for effecting relative progressive movement
between the pattern and the sensing means during the sensing
operation.
(1) Note. Either or both of the pattern or the sensing means
may move (e.g., pattern card or tape sensed while in motion
through the device, or a stationary record "scanned" by
moving pattern sensers.
(2) Note. As an alternative to moving the pattern or the
sensers, all points of a stationary pattern may be sensed
simultaneously and the data may be read out in steps (e.g.,
column-by-column) to the tool-selecting means, over a system
of shiftable connections (see subclass 66).

pattern has effected preliminary tool positioning.
Subclass:
77
This subclass is indented under subclass 76. Device
including yieldable individual tool-actuating power trains so
arranged that the tools which do not contact said pattern are
forced into cutting relationship with a workpiece.
(1) Note. The pattern functions as a mask or stencil to
block the operation of unselected tools.
(2) Note. See Fig. 1 (described in section II, (2) Note) for
illustrative mechanism.
Subclass:
78
This subclass is indented under subclass 76. Device
including individual tool-actuating power trains, said power
trains comprising spaced driving and driven elements with
lost motion or misalignment therebetween, and means to

driven elements so that portions of the pattern serve to
complete the driving power trains to the so-selected tools.
(1) Note. The pattern has the form of an inverse stencil
(i.e., having blank areas corresponding to holes to be
punched, and holes corresponding to areas to be left
unpunched).
Subclass:
79
This subclass is indented under subclass 59. Device provided
with mechanism to impart progressive relative movement
between the pattern and said sensing means between successive
sensing operations.
(1) Note. Feed* means is to be distinguished from means
which merely initially presents the pattern to the sensers,
or vice versa. In the majority of pattern-controlled
selective cutting machines, the pattern is advanced
continuously or intermittently during successive sensing and
cutting or punching cycles.

This subclass is indented under subclass 79. Device in which
the sensing means, in response to detection of a pattern
indicium or characteristic, moves a selected tool, or
initiates the transmission of force from a source of energy
to move said tool, into such position that (1) an actuating
power train is completed to drive said tool through its
working stroke, or (2) a latching or blocking mechanism is
caused to hold said tool in operative position while a
cooperating tool is actuated.

type.

117 for a tool selection means in general which effects
completion of a power drive train to a selected tool without
the use of an interposer.
Subclass:
82
This subclass is indented under subclass 79. Device wherein
the sensing means directly initiates or permits the
application of energy to a selected complete individual
tool-actuating power train.
(1) Note. A device classifiable in this subclass is termed
"direct-acting" in that the senser, although it does not
transmit tool-actuating force, controls and determines the
application of actuating force from a power source to a tool,
without the use of an interposer or other selecting means.
(2) Note. For example, the pattern-senser may comprise a
contact brush which completes an energizing circuit for a
tool-driving magnet upon detection of a hole in the pattern;
or the senser, upon detection of a pattern indicium, may
release a latch or restraining device for a yieldably-biased
tool, freeing the latter for actuation.

preliminarily by the sensing means.
Subclass:
84
This subclass is indented under subclass 79. Device wherein
the sensing means in response to the detection of indicia
effects the movement of an interposer*.
(1) Note. In a device of this type, the pattern-senser
generally controls the motion of the interposer, even though
a specific arrangement of biasing springs or weights may tend
to obscure this relationship.
Subclass:
85
This subclass is indented under subclass 84. Device wherein
said interposer moves bodily with and is effectively unitary
with said sensing means.
Subclass:
86
This subclass is indented under subclass 84. Device
including means which continually tends to move an
interposer* toward or from its effective position and
simultaneously to move the associated sensing means toward
its most advanced (i.e., indicium-responsive) position.
(1) Note. The mechanism typically comprises
cyclically-actuated means to retract the sensers from
engagement with the pattern, against the force of the biasing
means.
(2) Note. Fig. 16 illustrates typical mechanism of this
subclass. Pattern P and workpiece W are usually advanced in
step-by-step manner past the senser(s) S and tool(s) T. S is
biased by a weak spring toward contact with P, and is
retracted therefrom after each sensing operation by a
reciprocating bail B. When, in any cycle of operation, senser
S detects a hole in P (by entry therein) it causes sufficient
movement of its interconnected interposer I to control the
conditioning of tool T for cutting or noncutting, as desired.

pairs in response to an input-impulse.*
(1) Note. Tool acutation may follow as a result of
selection, or may be effected by independent means (e.g., by

(1) Note. The interposer when in effective position, serves
either (1) as the last link of the power train to the driven
tools of the selected pairs, or (2) as blocking means to hold
the "fixed" tools in effective position to cooperate with
their associated driven tools.
(2) Note. One of a plurality of elements which is movable

(1) Note. The interposers in this subclass function as
power-transmitting elements of the tool-driving train, as
distinguished from other interposers which serve merely to
block the "fixed" tools of the selected pairs and thus do not
transmit power.
(2) Note. Fig. 19 illustrates mechanism exemplary of this
subclass. The turret of interposers is adjustable to three
positions, in each of which a different combination of tools
is conditioned for actuation by the press ram acting through
the tool-aligned interposer lugs. [figure] [caption]Fig.

(1) Note. A coded selector member differs from a coded
interposer in that (1) it does not engage the selected tools,
and (2) it has only one effective position (as distinguished
from the differentially- positioned interposer of subclass
98). See Fig. 20 (under subclass 105) for a specific example
of a coded selector member.

found in subclass 97 above, in that it includes some form of
power drive trains between the coded element and a number of
a single interposers (i.e., each interposer controls a single
tool pair), while the coded interposer of subclass 97
consists of a unitary element which is engageable with a
pluralty of tools to control a plurality of tool pairs.
(2) Note. Fig. 20 represents typical basic mechanism of this
subclass. The differently positioned lugs on the levers of
keys A and B, constitute, with their levers,
coded-selector-means which are adapted to drive distinct
groups of interposers. [figure] [caption]Fig. 20. CODED
SELECTOR MEANS COMBINED WITH INTERPOSERS (subclass 105).
Subclass:
106
This subclass is indented under subclass 94. Device wherein
the tool-conditioning mechanism is constituted solely of
means to drive a plurality of tools through their cutting
stroke, or to directly initiate the transmission of actuation
force to a plurality of tools from a source of power.
(1) Note. A device of this type performs "coded direct
punching", by utilizing the movement of a key-lever or the
like, either to drive certain of the tools directly or to
actuate valves, clutches, or electrical contacts to apply
power to certain tools.
(2) Note. In this case the tool "selecting means" is not
distinct from the tool "actuating means"; tool "selection" is
achieved by applying power to a predetermined group of tools;
in other words, tool selection and actuation are effected
simultaneously by a common impulse through a common channel.
(3) Note. See Fig. 2 (described in the class definition) for
an illustrative example of mechanism classifiable in this
subclass. Compare Fig. 6 (independent tool-actuating linkages
lying side-by-side; no coding mechanism present).
Subclass:
107
This subclass is indented under subclass 106. Device wherein
the means directly controls the transmission of actuating
force to a plurality of tools from a source of power.
Subclass:
108
This subclass is indented under subclass 107. Device wherein
the means controls the application of electrical power to
electromechanical transducers associated with the tool pairs
to drive the same.
(1) Note. Fig. 21 illustrates circuitry and mechanism
typical of this subclass. Depression of a key closes circuits
to energize a group of tool-actuating solenoids.
(The lowermost key (D) is shown as controlling only one tool,
but at least two other keys control distinct subgroups of the
total number of tools, thus constituting
combinational-coding-means* under the class definition).
[figure] [caption]Fig. 21. DIRECT CODED ACTUATION, INDIVIDUAL
ELECTRIC DRIVES (subclass 108).
Subclass:
109
This subclass is indented under the class definition. Device
provided with mechanism to condition one tool pair.
(1) Note. This subclass (109) uncludes devices wherein a
member, when in effective position, engages and blocks
actuation of an associated tool. Such a blocking member is
not an interposer*, for it does not "engage a tool---for
actuation".
(2) Note. For original placement in subclass 109, a patent
must claim specific tool-selection mechanism.
SEE OR SEARCH THIS CLASS, SUBCLASS:
59 for pattern-controlled means to select one or more tool
pairs.
94 for means to select a plurality of tool pairs (i.e.,
combinational-coding-means).
Subclass:
110
This subclass is indented under subclass 109. Device wherein
the tool pair and its actuating power train are permanently
connected by actuating linkage having a portion which
normally has idling motion rendering the linkage ineffective
to transmit power to the tool, and wherein the conditioning
mechanism comprises an element movable into blocking
engagement with said portion to furnish a fulcrum therefor,
whereby said linkage is made effective to actuate said tool.
(1) Note. Fig. 22 illustrates basic mechanism of this
subclass. A continuously rotating crankshaft carries a
crankpin which is slidable in a longitudinal slot in the
actuating lever. The lever is restrained against longitudinal
movement by suitable guides, not shown, so that it oscillates
idly in a vertical plane during the normal or retracted
condition of the latch. Depression of key K projects the
latch into the path of idle movement of the lever,
constraining the latter to pivot about the latch as a fulcrum
and thus to drive tool T downwardly upon each rotation of the
crankshaft. [figure] [caption]Fig. 22Typical Mechanism of
subclass 110.
Subclass:
111
This subclass is indented under subclass 109. Device wherein
the tool- conditioning mechanism comprises an interposer*.
Subclass:
112
This subclass is indented under subclass 111. Device wherein
the interposer is movable to a plurality of effective
positions in each of which it engages and effects selection
of a different tool.
(1) Note. See Fig. 3 (described in the class definition),
for illustrative mechanism.
Subclass:
113
This subclass is indented under subclass 112. Device wherein
a plurality of interposers are movable as a unit to and
between said effective positions by rotation of said unit.
Subclass:
114
This subclass is indented under subclass 111. Device
including a source of mechanical energy and means effective
to transmit or make available said energy to move the
interposer to or from its effective position.
Subclass:
115
This subclass is indented under subclass 114. Device in
which the source of energy comprises an electro-mechanical
transducer for each interposer.
Subclass:
116
This subclass is indented under subclass 111. Device in
which the interposer in moving to and from an effective
position moves rectilinearly.
Subclass:
117
This subclass is indented under subclass 109. Device in
which said tool-conditioning mechanism comprises means
capable of moving a tool or an element of a tool-actuating
drive train into power receiving engagement with a movable
actuator.
(1) Note. The mechanism of this subclass is distinguishable
from the interposer mechanism of subclass 111 in that the
movable element is at all times drivingly connected to its
associated tool.
(2) Note. Fig. 23 illustrates typical mechanism of this
subclass. A dog or link, pivotally attached to tool T, is
movable into and out of alignment with reciprocable hammer H,
by positioning-linkage controlled by a key or other means.
[figure] [caption]Fig. 23.Typical Mechanism of subclass 117.
Subclass:
118
This subclass is indented under subclass 117. Device wherein
said moving means effects the movement of at least a portion
of a tool into such position that an actuating drive train
for the tool is completed.
Subclass:
119
This subclass is indented under subclass 117. Device wherein
the movable actuator has continuous rotary motion.
Subclass:
120
This subclass is indented under the class definition. Device
including means not provided for in the preceding subclasses,
which is responsive to a signal or impulse originating
externally of the device or from an unspecified source, to
control a disclosed tool-selecting mechanism.
(1) Note. A patent to the combination of an input-means*
(e.g., keyboard) and a specific tool selecting mechanism is
placed as an original in subclass 94 or 109 in accordance
with the type of selecting mechanism claimed. For original
placement in subclass 120, a patent should be drawn to a
specific input-means associated with a selective cutting
device whereof the selecting mechanism is disclosed but not
significantly claimed.
SEE OR SEARCH THIS CLASS, SUBCLASS:
59 for an input-means of the pattern sensing type.
Subclass:
121
This subclass is indented under subclass 120. Device wherein
the responsive means comprises a member which is capable of
adjustment to two or more positions, in each of which
positions it generates a distinct signal or impulse effective
to control the selection of tools to be actuated.
(1) Note. A differentially-positionable input element is
typically a slide bar, a drum or a pivoted lever, by means of
which a plurality of distinct tool-selection controls may be
obtained, as distinguished from a simple key or pushbutton
which has only one effective or control position.
(2) Note. The control signal or impulse of the subclass
definition is to be distinguished from the input-impulse*
which effects adjustment of the movable input member.
(3) Note. In many cases, a visual guide such as a numbered
scale, or a design to be reproduced, is associated with the
positionable input device but does not of itself exert a
control on the positioning of the input member (i.e., it is
not a pattern*).

40 for means to hold a picture or design to be traced by a
manually-movable stylus controlling tool selections.

Subclass:
122
This subclass is indented under subclass 120. Device wherein
the responsive means consists of a number of distinct
mechanisms or electrical circuits each responsive to such
signal or impulse from an external or unspecified source.
(1) Note. A number of patents which disclose plural input
channels are originally classified in subclass 121.
SEE OR SEARCH THIS CLASS, SUBCLASS:
45 for a device having independent manual input means for a
plurality of tool fields.
121 for a disclosure of plural input means of the
differentially-positionable type.
Subclass:
123
This subclass is indented under subclass 122. Device wherein
the distinct mechanisms comprise manually-actuatable levers
or push-buttons.
(1) Note. In general, the actuatable levers or push-buttons
found in this subclass have only one effective position and
one ineffective position, as distinguished from the
differentially positionable elements of subclass 121.
(2) Note. A patent disclosing novelty in keyboard or
key-linkage structure, or in the connections therefrom to a
tool- selecting mechanism, and not classifiable in a
preceding subclass, may be placed as an original in this
subclass. The broad recitation or disclosure of a key or
keyboard is insufficient for this purpose.
SEE OR SEARCH THIS CLASS, SUBCLASS:
106 for an example of a keyboard-controlled coded direct
punching device.
Subclass:
124
This subclass is indented under subclass 123. Device
including means, responsive to actuation of such keyboard
means to initiate, terminate, or modify an operation of the
device other than the selection of tools.

auxiliary keys for controlling the advance of a workpiece, is
disclosed in many of the more complex machines classified in
preceding subclasses.

This subclass is indented under subclass 126. Device
including means responsive to the selection of a particular
tool, or to the number or combinational arrangement of the
tools chosen for a cycle of actuation, to control the
work-feed varying means.
(1) Note. For example, in a selective tape punch which

characters), the increment of tape feed after each punching
cycle may be made equal to the length of tape occupied by the
character punched.

This subclass is indented under subclass 128. Device
provided with means capable of advancing a workpiece relative
to a tool field in either of two opposed directions.
(1) Note. The "back spacing" mechanism on a card or tape
punch is an example of such a device.
(2) Note. The work advance in this subclass (129) is
preparatory to a cutting operation, i.e., not the ejection of
work from the machine.
