Class 226
ADVANCING MATERIAL OF INDETERMINATE LENGTH
Class Definition:
In the class definition and in the subclass definitions,
terms which are followed by an asterisk (*) will be found to
be defined in the Glossary.
SUBJECT MATTER AND SCOPE OF THE CLASS
This is the residual class of inventions directed to a
process or apparatus for handling indeterminate-length*
material in one of the following ways: (1) moving such
material in a direction generally along said length
dimension, (2) sensing such material (which material is
disclosed as moving as in (1) above) and imparting additional
movement to, or otherwise controlling movement of, said
material responsive to said sensing, (3) threading a new
portion of such material into or through material moving
apparatus of the type defined in (1) above, or (4)
constraining such material through a certain path of movement
relative to a disclosed material moving apparatus of the type
defined in part (1) above, including insuring contact of the
material with said apparatus.
Patents placed as originals in this class (226) usually
disclose means to advance material to a material modifying
machine or from such machine to a destination. The mere
naming of the material modifying machine or of the
destination, in a claim, will not serve to exclude a patent
including such a claim from this class. See Lines With Other
Classes, "Relationship to Specific Classes", for further
notes to work treating classes which include feeding means.
This class (226) is intended as the repository for patents
disclosing the feeding material to a station where an
operation* is performed on the material. It is not intended
as the locus for original placement of disclosures wherein
the material being advanced is part of a machine, and that
material will itself operate or help to operate on work.
LINES WITH OTHER CLASSES AND WITHIN THIS CLASS
With certain exceptions, stated in subclasses 11, 91+, and
125+, there are no means recited in the claims contacting the
leading end nor the trailing end of the material, nor is the
leading or trailing end of material utilized to effect
movement thereof.
A. RELATIONSHIP TO SPECIFIC CLASSES
(1) The following classes (or subclasses within a class,
where noted) have been screened for patents classifiable in
this class (226) on the basis of the lines set out in
applicable class references, in References to Other Classes,
below: Class 83, Cutting; Class 140, Wireworking; Class 225,
Severing by Tearing or Breaking; Class 254, Implements of
Apparatus for Applying Pushing or Pulling Force); Class 312,
Supports: Cabinet Structure, subclasses 34.1+; Class 400,
Typewriting Machines, subclasses 611+.
Except as amplified below in this section the line between
this class (226) and the above classes is as stated in the
general relationships set forth in the following sections
below:
Material-modifying Classes Which Include Feeding Of
Indeterminate-length* Work; Other Classes Including Advancing
Of Indeterminate-length* Material; Other Material Handling
Classes; and Classes Which Include Subcombinations Utilizable
In Advancing Indeterminate Length* Material.
Other classes listed in these sections may contain patents
claiming feeder subcombinations in subclasses not
investigated as of the date of this publication. Such feeder
subcombination patents will remain as presently classified
until screening of these subclasses has been accomplished.
The lines formerly existing between this class (226) and the
"other" classes referred to above have not been changed,
except as noted in applicable class references under
References to Other Classes, below.
(2) The relationship of Class 226 to classes that warrant
specific mention are: See References To Other Classes below.
Specifically see: Class 33; Class 198; Class 225; Class 242;
Class 270; Class 271; Class 281; Class 312; Class 352; Class
414; Class 462; Class 474. See References to Other Classes,
below.
(3) The relationship between this class (226) and other
classes set out under the headings below (and their
associated class references in References to Other Classes)
have been arranged so that a relationship set out under the
first appearing heading (Relationship to Material-Modifying
Classes Which Include Feeding of Indeterminate-Length* Work)
shall govern over a relationship set out in any of the later
appearing headings in the event of any apparent discrepancy.
B. RELATIONSHIP TO MATERIAL-MODIFYING CLASSES WHICH INCLUDE
FEEDING OF INDETERMINATE-LENGTH* WORK
The following considerations will govern the decision as to
original placement of a patent in this class (226) or in one
of the subject classes:
(1) This class (226) takes original patents directed to
apparatus for feeding material in combination with means to
modify, treat or operate on such material only if said means
is recited as a named means or element, and only if said
means is not claimed as moving or operating in timed or
synchronous relationship to the operation of the feeding
apparatus. For example, any one of the following recitations
in a claim will not (in and of itself,) bar original
placement in this class: "press", "cutter", "dryer", (or
"drying chamber"), "recorder", "impression cylinder"
"wrapping machine", or "transducer head". Claim language
directed to a nominal combination expressed as an operation
station (e.g., cutter, press, printer, etc.), spatially
located with respect to a feeder also will not bar original
placement in this class (226). However, the following
recitations in a claim will be considered as details which
will bar original placement in this class, and will be reason
for placing a patent claiming such details in the appropriate
treating class; "a rotary printing press", "a reciprocating
cutter", "a heated drying chamber"; or operative structure
such as "means to synchronize the operation of a cutter and a
feed means", "means to stop tape feed as the recorder head is
moved out of recording position". (It should be understood
that the above words and phrases are exemplary, and that
equivalent terms will be given the same effect where
appropriate).
(2) This class does not take original patents claiming
processes for feeding material in combination with any
process for modifying material even though such modifying
step is broadly recited (e.g., "and treating the material").
Patents reciting such combinations will be placed as
originals in the appropriate class or subclass pertaining to
the treating process on the basis of the material modifying
step or steps.
The locus of patents disclosing web or strand feeding
combinations classified in the subject classes is as follows:
(These references are to be considered merely indicative of
the art in the class, and should not be considered as
exhaustive.)

Class 8, Class 19, Class 26, Class 28, Class 38, Class 57,
Class 66; Class 68; Class 87; Class 139; for specific class
references related to this subject class.
Printing Communications and Analogous Arts -
See References to Other Classes, below. Specifically see:
Class 101; Class 118; Class 178; Class 235; Class 281; Class
346; Class 360; Class 369; Class 400; Class 462.

See References to Other Classes, below. Specifically see:
Class 29, Class 53; Class 59; Class 72; Class 76; Class 131;
Class 227; Class 413; Class 470; Class 493
Material-Working or Material-Treating Arts -
See References to Other Classes, below. Specifically see:
Class 19; Class 34; Class 65; Class 72; Class 83; Class 100;
Class 112; Class 134; Class 140; Class 142; Class 144; Class
225; Class 261; Class 264; Class 266; Class 270; Class 408;
Class 425; Class 432; Class 446; Class 451.
C. RELATIONSHIP TO OTHER CLASSES WHICH INCLUDE ADVANCING OF
INDETERMINATE-LENGTH* MATERIAL
The subject classes referred to in this section include
patents directed to the combination of advancing such
material plus an operation other than a treatment of, or a
working on, such material (i.e., the material is not changed
during its movement). This class (226) will not take
original patents disclosing the combination referred to
above, if such material is disclosed as being an intimate
part of the apparatus (or method of using the apparatus), or
is claimed in combination with elements not performing a
material advancing function. For example, a patent
disclosing a cable, one or more sheaves, cable-moving means,
and a load on the cable to be moved thereby, will be placed
in an appropriate "pulling" class, listed in References to
Other Classes on the basis that the cable and its mover are
intimate parts of the pulling apparatus. Similarly, moving
picture projecting apparatus (or method involving use of such
apparatus) will be placed in one of the "viewing" classes
listed in References to Other Classes on the basis of claimed
projection lens plus film gate (comprising an optical
system). The class lines between this class (226) and the
subject classes (especially those classes listed in
References to Other Classes are more fully discussed in the
section, Relationship to Specific Classes, in Lines With
Other Classes.
The locus of patents disclosing combinations classified in
the subject classes is as follows:
Pulling or Hoisting Arts -
See References to Other Classes, below. Specifically see:
Class 15; Class 37; Class 43; Class 104; Class 166; Class
187; Class 212; Class 221; Class 254; Class 294; Class 474.
Viewing or Exhibiting or Analogous Arts -
See References to Other Classes, below. Specifically see:
Class 40; Class 84; Class 178; Class 352; Class 355; Class
360; Class 369; Class 399.
Other Advancing of Indeterminate Length* Material -
See References to Other Classes, below. Specifically see:
Class 219; Class 242; Class 270; Class 312; Class 314.
D. RELATIONSHIP TO OTHER MATERIAL HANDLING CLASSES
The subject classes referred to in this section include
original patents directed to a moving means capable, as
disclosed, of moving various types of material. This class
(226) is the locus of inventions whose sole disclosed use is
the advancing of indeterminate-length* material. Other
appropriate classes referred to in this section will take
patents wherein the disclosure is vague, or is specific to
handling of various types of material. It should be noted
that specific exceptions to this last-mentioned line are
provided for in Relationship to Specific Causes.
For the locus of patents disclosing material handling
combinations, see References to Other Classes, below.
Specifically see: Class 193; Class 198; Class 221; Class 222;
Class 271; Class 406; Class 414; Class 453.
E. RELATIONSHIP TO CLASSES WHICH INCLUDE SUBCOMBINATIONS
UTILIZABLE IN ADVANCING INDETERMINATE LENGTH* MATERIAL
This class does not take original patents directed only to
subcombinations of general utility in either this class (226)
or other classes, which subcombinations are specifically
provided for in other classes. Specific exceptions to this
line may appear in Relationship to Specific Causes above. A
patent, to be placed originally in this class, should claim
more than the subcombination, that is, it should recite the
means for, or a step of, advancing of material as the end
result, and/or the cooperation of the subcombination with the
material-advancer.
The locus of patents disclosing subcombinations which are
utilizable in advancing indeterminate length* material,
listed below in groups pertaining to common subject matter,
is as follows:
Detection of Material Breaking or Exhaustion:
See References to Other Classes, below. Specifically see:
Class 19; Class 34; Class 200; Class 242.
Other Detection of Material:
See References to Other Classes, below. Specifically see:
Class 26; Class 28; Class 33; Class 57; Class 66; Class 72;
Class73; Class 83; Class 118; Class 139; Class 192; Class
200; Class 242; Class250; Class 318; Class 340.
Driven Feed-Roll:
See References to Other Classes, below. Specifically see:
Class 19; Class 72; Class 492.
Active, but Nondriven Means (e.g., a Roll, or a Pulley) for
Guiding Material:
See References to Other Classes, below. Specifically see:
Class 16; Class 68; Class 72; Class 100; Class 193.
Passive Means for Guiding Material:
See References to Other Classes, below. Specifically see:
Class 16; Class 34; Class 43; Class 57; Class 72; Class 83;
Class 112; Class 225; Class242; Class254; Class 289; Class
396; Class 400.
Material-Movement Retarding Element (e.g., a "Tensioner"):
See References to Other Classes, below. Specifically see:
Class 28; Class Class 66; Class 72; Class 87; Class 112;
Class 139; 188; Class 225; Class 242.
In general, the classes listed above fall into one of two
categories; (a) those combination classes having therein
subclasses pertaining specifically to subcombinations which
are also subcombinations for this class (or pertaining to
combinations found in this class (226) excluded herefrom
because of the combinational aspect of the class wherein the
subclass is located), or (b) those classes which are of
themselves subcombination classes, the devices of which are
of general utility.
The classes referred to as falling within (a) above may be
identified by their having been discussed or listed in the
following sections:
Material-Modifying Classes Which Include Feeding of
Indeterminate-length* Work;
Classes Which Include Advancing of Indeterminate-Length*
Material; or
Other Material Handling Classes.
Thus the classes referred to as falling within (b) above may
be identified by their being listed only in this section
(i.e., Classes Which Include Subcombinations Utilizable in
Advancing Indeterminate Length* Material).
LINE BETWEEN CLASS 26 AND CLASS 226
See Class 26, Textiles: Cloth Finishing, subclasses 71+ for
structure for feeding a cloth web while simultaneously
stretching or otherwise expanding the cloth. See, for
example: subclass 71 (the principal subclass) for web feed
means in series, each successively accelerated whereby
stretchingly to tension the web (and compare this with Class
226, subclass 195); 74+ for web condition- responsive means
to control the simultaneous feed and stretch operation (and
compare with Class 226, subclasses 10+; particularly Class
226 subclasses 15+, since edge detection and registration
control is frequently involved); and subclasses 97 and 99+
for means simultaneously to stretch and feed the cloth web by
contact with orbitally traveling surface means.
LINE BETWEEN CLASS 242 AND CLASS 226
Class 226 currently provides for an "orbitally traveling
material*-engaging surface(s)" in subclasses 168+ and "with
means to retard material* movement (e.g., "tensioner")" in
subclass 195 which conflict with Class 242 subclasses 147+,
157+, 410+, and subclasses 615+. Plans are underway to
resolve this conflict by making Class 242 subclasses 147+,
157+, 410+ and 615+ the residual location for their
respective features, with Class 226 subclasses 168+ and 195
being limited to their respective features combined with a
material* feeder*. This has already been resolved for Class
226 subclass 196.1.)
LINE BETWEEN CLASSES 312, 226, AND 242
Class 226 will take an original patent claiming means for
positively moving such indeterminate-length* strip provided
that the supply roll and its mounting is not specifically
recited. See the line between Class 242 and Class 226,
above. A patent claiming a device wherein the strip is
directly grasped to pull the strip out of the cabinet, will
be placed as an original in Class 312.
LINE BETWEEN CLASS 462 AND CLASS 282
Class 462 includes patents directed to a casing having
supported therein a manifold set (which is the name applied
to a plurality of strips alternately interleaved with carbon
strip) and a writing platen over which such material is
trained. Placement of a patent in Class 282 will be on the
basis of the environment, including the writing platen, or on
the basis of claims directed to the manifold set.
LINE BETWEEN CLASS 474 AND CLASS 226
See particularly Lines With Other Classes and Within This
Class in Class 474 for the line between Class 226 and Class
474.

270, Sheet-Material Associating includes movement of web
material to a claimed web associating operation, in subclass
52. The mere naming of "an associating station", (or
equivalent term) will not bar placement of an original patent
in this class (226). However, claimed recitation of such
station plus inherent associating structure (e.g., "turning
bars", "guide bars", etc.,) wherein it is clear that plural
webs are directed to a common line of travel, will be reason
for placing an original patent so claimed in Class 270. A
patent claiming the movement of plural webs out of a common
line of travel into plural lines of travel, or claiming a
subcombination of plural guide bars disclosed as for the
above-stated purpose, will be placed as an original in Class
270. (See Lines With Other Classes and Within This Class,

271, Sheet Feeding or Delivering, includes movement of sheets
to an operation or from an operation. The line between Class
226 and Class 271 is based on disclosure of the material
acted upon. Patents which clearly disclose feed or delivery
of sheet-like articles only, will be placed in Class 271,
even though such structure is capable of feeding web
material. Original patents which clearly disclose movement of
web material as well as sheets and claim means which is
capable of moving either, will be placed in this class (226).

281, Books, Strips, and Leaves, includes patents directed to
a casing having supported therein a roll of web material, and
a writing platen over which such material is trained.
Movement of such material may be as a result of direct
contact of the operative's hand with the material or as a
result of a roller manipulated by the operative; but the
environment, especially the provision of a casing and a
writing platen, will be reason for placing a patent claiming
such features in Class 281. (See Lines With Other Classes and
Within This Class, section A (2) above.)
281, Books, Strips, and Leaves, subclass 8 and 11. (See

352, Optics: Motion Pictures, includes the combination of
material moving means and an optical system. This class
(226) will take an original patent claiming a device for
moving material (e.g., a film) past a named "lens",
"shutter", "gate", or equivalent motion picture means.
However; the recitation in a claim of mechanism for operating
such named element, or a plurality of such elements recited
as to establish optical or mechanical cooperation between
such elements as to make an optical system, will bar original
placement in this class (226). For example a patent claiming
"a gate and means for moving the gate" or " a gate and a
lens" will be placed originally in Class 352. (Also see Lines

GLOSSARY:
CARRIER
(n) As used in this class, a member on which a material
engaging part is slidingly or rotatably (including pivotally)
mounted, which member entirely supports the part against
gravity while allowing relative movement between the member
and the part. This term is applied only to that member of a
device which is immediately connected to the
material-engaging part. A member can be a complex of parts
which move integrally together.
DISPENSER
(n) A device which moves material to an operative (e.g., a
person who operates such device and who will use the
material). (Compare with Feeder).
FEED
(v) To move material to an operation*.
(n) The act of moving material to an operation*.
FEEDER
(n) A device which moves material to an operation*. (Compare
with Dispenser).
FEED-ROLL
A roll* which is disclosed as driven so as to impart motion
to the material whereby the material is moved to an
operation.
GRIPPER
(n) As used in this class, a movable device comprising a
plurality of substantially opposed surface elements (commonly
termed jaws) relatively movable toward and away from a common
line or plane (to engage corresponding opposed areas on
material) and hold such material frictionally to the
elements, whereby additional movement imparted to the
elements in a material advancing direction will also be
imparted to the material.
INDETERMINATE LENGTH
An extent of material having the characteristic that the
longitudinal dimension of the material is effectively
infinite insofar as can be determined from the claimed
structure for advancing such material. The term applies to
an extent of material in which the distance between the ends
is irrelevant to the manner of, or structure for, handling
and/or moving such material. Thus, except for the lead-end
threaders of subclass 91, the leading or trailing end of the
material is not utilized by the claimed means for moving the
material, nor recognized in a claimed method of moving. The
term as used in this class also applies to material which is
formed in a closed loop, (i.e., the leading end and the
trailing end of definite length material have been joined
together). However, the lead end may be used in stopping the
material to effect intermittent advance as in subclasses
125+, and a trailing end (effected by a break or depletion of
material) may be sensed to stop operation of the advancer.
LATERAL
As used in this class, the term refers to that direction
simultaneously perpendicular to the longitudinal* direction
of movement of a web* and parallel to the surface of the
web.
LONGITUDINAL
As used in this class, the term refers to the direction along
the length of the indeterminate-length* material.
MATERIAL
The work, stock, web, strand or other interconnected stuff
which is being advanced.
OPERATION
(n) A performing of work or a doing of an act. Exemplary
operations are: cutting, recording, viewing, dyeing.
RECESSED-ROLL
A roll* having a radially stepped periphery, the radially
outward portion engaging material and the radially inward
portion(s) not engaging the material.
ROLL
A shaft-mounted rotatable body, usually cylindrical, a
portion of the periphery of which engages material. Although
a roll is usually cylindrical, the term is used in this class
to include a conical, truncated conical, or spherical body, a
portion of the periphery of which engages the material to be
moved.
ROLL-COUPLE
A group of at least two rolls*, material being disposed
therebetween in simultaneous tangential and/or peripheral
engagement with all rolls, the roll(s) on one side of the
material counter-rotating relative to the roll(s) on the
other side of such material. An example of a roll-couple
comprising more than two elements, is a plurality of
equal-diameter rolls co-axially mounted, all of which rolls
are opposed by a single, parallel roll.
STRAND
Material having a cross-section (transverse of the
longitudinal* dimension) of substantially similar width and
depth dimensions (compare with Web). Exemplary strand
materials are: rod, tube, cordage (i.e., rope, cable, etc.)
chain, filaments, yarn, wire.
WEB
Material having a cross-section (transverse of the
longitudinal* dimension) of relatively thin dimension
perpendicular to a relatively wide dimension (compare with
Strand). Thus, the material has two side edges defining its
lateral* boundaries, and two surfaces defining its other
cross-sectional boundaries. Exemplary web materials are:
fabric, screening, strip.
SUBCLASSES
Subclass:
1
This subclass is indented under the class definition.
Method.
(1) Note. See Lines With Other Classes and Within This
Class, Relationship to Material-Modifying Classes Which
Include Feeding of Indeterminate-Length* Work, of the Class
Definition for considerations relating to a feeding process
in combination with a material modifying step or steps.
Subclass:
2
This subclass is indented under subclass 1. Method in which
is recited the step of aligning material with respect to a
predetermined point (fixed or movable) either (1)
transversely* or (2) longitudinally* of the direction of feed
of the material.
(1) Note. In patents wherein the material is disclosed as
stopped during the operation it is clear, because of the fact
of stopping, that there is a particular duration of time in
which the material is aligned with a fixed point. However,
the disclosed alignment of material is not limited to
alignment of the material with respect only to a fixed point.
In the event that continuously moving material is operated
on during movement thereof, especially in such arts as
printing or cutting, longitudinal registration involves
alignment of a particular point or zone of the material with
respect to a particular reference point or zone on the
operating machine during only a particular instant of time,
during which instant a moving operating element of the
machine is also aligned with respect to the same reference
point on the machine. Thus, the moving point of the material
is in registry with the moving element of the machine. In
those disclosures, wherein an index (e.g., a printed spot, a
perforation, etc.) is provided on the material, longitudinal
registration, as disclosed, involves sensing of the index,
comparing the signal produced by the sensing with reference
to the moving operating element, and correcting the speed of
the material (or of the element) to effect the registration
as defined. The operating element may be broadly recited in
the claims of a patent placed originally in this class (see
section Lines With Other Classes, Relationship to
Material-Modifying Classes Which Include Feeding of
Indeterminate-Length* Work). Patents disclosing structure to
perform longitudinal registration are to be found in
subclasses 27+ and structure to perform lateral registration
are to be found in subclasses 15+.
(2) Note. Correction of material speed, not responsive to
material indicia, but responsive to undesired speed changes,
is related in concept to index-responsive speed correction,
and patents disclosing structure to perform such speed
correction are to be found in subclasses 24+ except
subclasses 27+.
(3) Note. An original patent disclosing correction of the
speed of the material and, alternatively, the speed of the
operating element, and claiming correction of speed, without
specifying in the claims which speed is corrected, is
properly placed in this class (226) in this subclasses 2+ as
processes or in the appropriate apparatus subclasses 24+. A
patent which discloses correction of the speed of either the
operating element station; or, a patent which discloses
correction of the speed of the material and of the element
station; will regardless of how claimed, be placed in the
operating class such as Class 101 (Printing) or Class 83
(Cutting), in appropriate subclasses.

Subclass:
50
This subclass is indented under subclass 49. Device provided
with at least two driven material-engaging advancing
elements, only one or only another of which is selected for
advancing engagement with the material at any one time.
(1) Note. The usual example of claimed subject matter
placed herein involves a feed-roll-couple* comprising one
driven roll* and one pressure roll engaging material on
opposite sides thereof, and another feed-roll-couple separate
from the first-mentioned couple. However, a patent claiming
a first feed couple comprising a first driven roll
cooperating with a pressure roll to feed material which is
between the rolls and a second feed couple comprising a
second driven roll cooperating with the same pressure roll,
the pressure roll engaging with either the first or the
second driven roll to move the material either in one
direction or in an opposite direction, would also be placed
herein since the common pressure roll is alternatively part
of the first feed couple or the second feed couple.
(2) Note. Also included herein are exemplary patents
disclosing two separate feedroll*, each rotated by its own
drive shaft, in which one shaft is connected through a clutch
to a power source or the other shaft is connected through
another clutch to the same power source. The shafts are
oppositely and alternatively driven through their respective
clutches whereby the material is advanced in a forward or
reverse direction. For other patents wherein the same roll
is driven alternatively in opposite directions, see subclass
51.

This subclass is indented under subclass 49. Device provided
with a material-engaging advancing means connectable to first
means moving said advancing means in one direction, or to

Subclass:
52
This subclass is indented under the class definition. Device
including means (hereafter referred to, in the definitions of
the indented subclasses, as a prong) to contact variations of
indeterminate length* material, said variations recurring
along the length-direction of said material.
(1) Note. In original patents placed in this and indented
subclasses, the variations described above are usually
perforations, holes, or notches in web material (the most
common example being motion picture film), and the means
contacting said variations comprises one or more claws,
sprocket wheels, pin-belts, or other toothed members, the
teeth of which enter into the perforations successively and
are moved to feed the perforated web. For simplicity and
brevity, the term "prong" (or "prongs") will be used
hereafter where appropriate to refer generally to a toothed
member described above.
(2) Note. To be placed as an original in this or indented
subclasses, a patent must (1) disclose the material as having
a modified surface such as perforations, and (2) claim the
prong (or prongs) or equivalent term (for an exemplary
listing of which, see (1) Note above). A patent which claims
a prong or its equivalent will be originally placed into
these subclasses only if it is clear from the disclosure that
material is moved (or stopped, as in subclasses 55+) thereby.
However, since material such as perforated film is sometimes
handled and fed as ordinary strand or web without using such
perforations (e.g., motion picture film passing a sound head
by friction drive means), mere recitation of perforated film
will not of itself warrant original placement into these
subclasses of a patent including such recitation.

(1) Note. The patents in this subclass are not to be
confused with the patents of Class 83, Cutting. To be placed
herein, the perforating or penetrating means must be
disclosed solely as means facilitating feed and the
perforations produced must be unused at any other time for
any purpose. Furthermore, if the patent discloses a
nonfeeding use for such perforations, placement of the
original patent will be in Class 83 on the basis of the
structure producing such perforations or in another class on

(1) Note. A "set" comprises a plurality of prongs all of
which partake of the same movement. Included within the
meaning of the term "set", as used above, is a pinwheel
assembly comprising two coaxial, equal-diameter sprockets, or
a claw having at least two teeth spaced laterally* of the
material, where in either case all the teeth of a set coact
simultaneously in at least two laterally opposite marginal
perforations in the same web to move said web. To be placed
herein as an original, a patent disclosing such a set would
also disclose and claim another sprocket of pitch diameter or
lateral spacing or speed of movement different from the
first-mentioned set, thereby, for example, to feed one web at
a speed different than another even through the rotational
speed of the sprocket remains unchanged, or to feed webs of
different lateral widths, or such patent would disclose and
claim another set of prongs (on the same claw described
above, or on a different claw) wherein the speed of movement
or the lateral spacing of the prongs comprising such other

This subclass is indented under subclass 52. Device in which
said prong contacts the variations periodically to hold said
material against motion in any of (1) a forward direction or
(2) a rearward direction or (3) both directions.
(1) Note. The prong of the patent placed herein may produce
movement of the material either forwardly or rearwardly of
normal travel, by reason of the shape of the prong and/or
movement thereof, as it engages the variation to effect
registration of the material. However, such additional
material movement is deemed to be incidental since no
material movement takes place if the material is properly
located when the prong engages the variation.

This subclass is indented under subclass 52. Device provided
with either (1) only one prong, or (2) a plurality of prongs,
all spaced longitudinally*, all mounted in fixed relationship
with, or integral with, each other, and all acting as a
single group; the prong of (1) or the prongs of (2) as a
single group being given a compound motion involving (a)
movement into contact with a variation in the material, (b)
rectilinear or arcuate movement longitudinally* of the
material while in contact therewith to move said material,
(c) movement away from contact with the variation and (d)
longitudinal movement in a reverse direction while out of
engagement, back to a starting position from which the
movements are repeated.
(1) Note. Patents in this and indented subclasses are
distinguished from patents in such subclasses 74+ and 76+ by
the nature of the movement imparted to the prong(s). The
patents placed in this and indented subclasses disclose a
prong which is substantially constantly oriented with respect
to the perforated material; that is, a free end of the prong
always points toward the material. For patents disclosing
prongs constantly oriented with respect to the material but
which are not fixed with respect to each other as required by
(2) of the definition of this subclass (62), see subclasses
75 and 81.
(2) Note. The patents placed in subclasses 74+ disclose a
prong mounted on an endless belt, chain or the like traveling
about two spaced, parallel, rotated shafts or driving
sprockets. In some disclosures (of subclasses 74+) the prong
may be relatively fixed to the belt to rotate, during one
orbit of a prong, once about an axis through the prong and
parallel to the shafts. In other disclosures the prong may
be mounted on two chains such that it is oriented to always
point towards the material, but no confusion should exist
since the prong is mounted on an endless belt or chain.
(3) Note. The patents placed in subclasses 76+ disclose a
rotated wheel or drum having prongs radially mounted thereon,
such devices being so different in structure and operation as
to be readily distinguishable from a claw. However, attention
is specifically called to certain patents placed in subclass
81 (indented under subclass 80) in which a rotating disc is
provided with a plurality of pins rotating oppositely with
respect to the disc in a one-to-one ratio, whereby the prongs
point always toward the material during feed thereof.

This subclass is indented under subclass 62. Device provided
with at least two prongs (or sets of prongs), each mounted
separately from the other(s), in which first one prong (or
set) engages and moves the material and subsequently another
prong (or set) engages and moves the material, in successive
material-feeding movements of the separate prongs (or sets).
(1) Note. The term "set" is used herein in the same sense
as in (1) Note of subclass 54.
Subclass:
64
This subclass is indented under subclass 62. Device provided
with means volitionally to adjust or vary either (1) the
distance, or (2) the route, traversed by the prong in its
orbital to-and-fro movement.
(1) Note. The term "range", as used in these subclasses is
applied to the path of claw movement and not to the throw of
the claw, i.e., the amplitude of claw movement. The
mechanisms are sometimes referred to as "framers".
(2) Note. The patents placed in this subclass (64) are to
devices which only vary the extent of claw movement. For
those devices which vary the range only, or the range and
extent, see subclasses 65 and 66 indented hereunder.
Subclass:
65
This subclass is indented under subclass 64. Device wherein
said means changes the route traversed by the prong without
varying the distance traversed.
(1) Note. The patents placed herein may have additional
means to adjust the extent to claw movement.
Subclass:
66
This subclass is indented under subclass 65. Device in which
the range of claw movement is moved so as not to intercept
the path of material, whereby material movement is stopped.
Subclass:
67
This subclass is indented under subclass 62. Device provided
with a carrier* movable to-and-fro in a straight line or
plane parallel to the direction of movement of the material,

72
This subclass is indented under subclass 70. Device in which
the prong is reciprocal relative to the carrier along a line
passing through, and perpendicular to, the axis of the

(1) Note. See (1) Note of subclass 73 for the differences
between the structures of this subclass (72) and subclass
73.
Subclass:
73
This subclass is indented under subclass 62. Device provided
with a stationary rod, in which device the prong is integral
with, or fixed to, a slotted member having a compound
movement combining both (1) a reciprocation along the slot
radially of said rod and (2) oscillation about the rod.
(1) Note. The claw member of this subclass (73) is similar
to that of subclass 72 and usually the motion is similar.
The basic difference between the patents of the subclasses,
lies in the joint between the claw member and the fixed stud
or axis. In patents placed in this subclass (73) a slotted
claw member slides directly on the fixed stud as the member
oscillates about the stud. In some patents placed in
subclass 72 a pivotable block is interposed between a slotted
claw member and the fixed axis or stud; the slot of the claw
member slides on the block, and the block oscillates about
the axis.
Subclass:
74
This subclass is indented under subclass 52. Device

This subclass is indented under the class definition. Device
including at least one member (hereafter referred to, in the
definition of the indented subclasses as girt) having an axis
extending laterally* of the material to be moved, in which
device as disclosed, (1) a plurality of such members receive
and support a loop of indeterminate length* material, the
material depending downwardly from supporting contact with
one such member and then upwardly to supporting contact with
another such member, (2) means are provided to give
translatory movement to said member(s) in a direction
simultaneously perpendicular to said axis and broadside to
said loop, and (3) the material has substantially no movement
relative to said member(s) during such translatory movement.
(1) Note. The terms bar, stick, rod, etc., are synonymous
with the term "girt" in this art.
(2) Note. In usual operation, a portion of the material at
a loading end of the festooner is draped or held relatively
stationary over a girt, a succeeding portion of that material
is advanced longitudinally, (generally in a vertical
direction) until a quantity of material is looped between the
girt and the loading (or infeed) means, a portion of that
material is draped over a succeeding girt while all or some
of the girts move bodily in a direction perpendicular to the
axis of the girts and broadside to the loop thus formed
(generally in a horizontal direction) and the material is
removed from the individual girts as the girts advance.
(3) Note. To be placed in this group of subclasses a patent
must claim the device in such terms that it is clear, or it
can reasonably be inferred, that a definite loop is found
between girts. Devices not clearly within this group may be
found in subclass 170, endless conveyors.
(4) Note. The mere naming of a device as a "festooner" or
equivalent phrase does not warrant placement of a patent with
such a recitation in this group. The significant
characteristic herein is the translatory movement of the
girts broadside to the loops. Other devices, sometimes named
as festooning machines, but in which the material moves in a
sinuous path over and under rotated or rotatable rolls.

(1) Note. This subclass includes only those patents in
which the claims specifically set forth the change of rate of
travel during each step. It is obvious that in any
intermittent feeder the material must accelerate from zero
and decelerate to a halt, thus patents have not been placed
in this subclass on that basis. The patents herein disclose
devices which provide specific means which may, for instance,
provide a slow acceleration to start the material, than a
faster acceleration for some duration of time and then a
deceleration to bring the material to a halt.

(1) Note. It is clear that any material-advancer which fits
the limitation that advance is intermittent must inherently
provide for some limit on the increment of advance. To be
placed in this and indented subclasses, a patent must
disclose and claim more than inherent limit on advance, that
is, it must specifically claim a limiting element in, or
acting on, the drive train of a manually powered material
mover.
Subclass:
130
This subclass is indented under subclass 129. Device
provided with structure for moving the restricting means to

advancement.
(1) Note. For example, (1) a limiting part which is moved
out of a position wherein material advancer is limited or (2)
an element on which such part is mounted for movement, are
both considered to be means to disable operation of the limit
means.

(1) Note. This subclass is the locus of patents claiming
means at one location for moving material plus means at a
second location for retarding such movement, whereby a pull
is effected on such material between said locations. This
subclass is not the locus of patents disclosing a "dancer"
roll {i.e., a roll for tautening that slack, (i.e., tendency
toward looseness) occurring in material suspended between two
spaced material-supports}; for such a "dancer", see
subclasses 27+ (and specifically subclass 44), 21, and 168+
(specifically subclasses 190+). The word "tensioner" has
acquired a variety of meanings in all of the arts relating to
advancing of indeterminate-length* material. Patents
disclosing a means (often termed "tensioner") for retarding
the advance of material moving to a work station may be found
in the classes and subclasses referred to in Lines With Other
Classes and Within This Class, Relationship to Classes Which
Include Subcombinations Utilizable in Advancing Indeterminate
Length* Material, in which classes "tensioner" may also mean
a "dancer" as used herein.

PASSIVE GUIDE:
This subclass is indented under the class definition. Device
comprising means to direct or confine the material* acted
upon or affected only by external force.
(1) Note. The mere support, or prevention of downward
movement, of material* under the influence of gravity is not
significant as a guiding function. An inclined plane or the
like, (which is utilized not for mere support of the
material*, but to conduct it, or facilitate its deflection,
to a different level) has a guiding function.
(2) Note. The "passive guide", in this and indented
subclasses, performs its function without the necessary
application of power thereto; it directs, deflects, orients,
etc., the material* without furnishing any propelling force
in the general direction of material* movement.
