speaking, the recording of intelligence by cutting is proper
subject matter for Class 101, Printing. More particularly,
individual cases of cutting machines or method may be tested
for aptness to Class 101 by reference to the following
statements: (a) A patent for a machine or process for cutting
on or adjacent the printed or written matter on a document to
prevent unauthorized or fraudulent alteration of such matter
due to the proximity of the cut surfaces to the printed or
written matter (e.g., check protecting) will be placed
originally in Class 101, 3.1 ; (b) A patent for a machine or
process for cutting work in the form of a character, a
design, or a pattern which will impart information to an
observer is proper for Class 101, subclasses 3.1+, if a cut
is disclosed as extending only part way through the thickness
of the work (e.g., embossing). If all of the cuts forming
such character, design, or pattern are disclosed as extending
all the way through the thickness of the work, and the work
is of wood, the patent will be found in Class 144; (c) If in
addition to a cutting machine or process of this class 144
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), such an
addition has been considered sufficient to place a patent
directed to such combination in Class 101, subclasses 3.1+.
This is in accordance with the general rule that a patent for
a combination of cutting with another treatment of the work
will be placed in the class of the other treatment; (d) An
original patent claiming both the process and apparatus for
the manufacture of stencils by cutting, or only such process,
will be found in Class 101, subclass 128.4.

WITH USE OF CONTROL MEANS ENERGIZED IN RESPONSE TO ACTIVATOR
STIMULATED BY CONDITION SENSOR:
This subclass is indented under the class definition.
Subject matter including means, or a step of using means, for
(a) detecting any of the following characteristics: a state
or property, a change in a state or property, or the
occurrence of a predetermined event, in any of the following:
the work*, the product of a machine, the machine itself, any
part of the machine, or the environment of the machine
affecting the operation thereof; (b) initiating (as a direct
result of such detection) a force or impulse other than that
generated or transmitted by the detecting means; and (c)
regulating or modifying (as a direct result of such
initiation) the operation of said machine.
(1) Note. This definition requires a patent to claim at
least four instrumentalities (or the use thereof) for
original placement herein. One of these must be a woodworking
machine or a device (e.g., work feeder, work heater, product
handler) necessary to the proximate function of woodworking.
The other three are (a) a sensor (e.g., photocell system,
trip lever, pressure diaphragm) to detect a condition as
stated in (a) of the definition, (b) an activator (e.g., an
element to make or break an electric circuit, a clutch, a
valve) to cause a release of energy more than, or different
from, that accounted for by mere change in condition (e.g.,
position or movement) of the sensor while it is functioning,
and (c) a controller (e.g., a motor or driver for said
machine or device) to change or cause the operation of said
machine or device. Therefore, a cam follower (or sensor)
directly linked to a controller, whereby follower movement
directly effects controller movement, is not proper subject
matter for this subclass due to lack of an activator as
defined. On the other hand, disclosure of a cam follower that
makes and breaks an electrical circuit that energizes a motor
may be placed herein.
(2) Note. A voluntary act of the person operating the
machine is not proper subject matter for this subclass. For
example, disclosure of an on/off switch on a woodworking
machine manipulated by an operative to start and/or stop the
machine (even though the switch initiates a release of
energy), should be considered for subclass 1, but is not
classified herein.
(3) Note. The machine that is regulated by the control means
is not limited to a woodworking machine of this class. It can
be another machine associated with the woodworker if the
claim reciting the other machine and woodworker is acceptable
for original placement into Class 72.
(4) Note. The control system disclosed in the patents of
this and indented subclasses are similar in concept to
control systems of other classes, particularly Class 226,
Advancing Material of Indeterminate Length, and Class 83,
Cutting. The total operations and the claimed combinations
are, of course, different, but the control systems, per se,
found in Classes 226 and 83 are usually analogous to those
herein, and may be applicable to the machines of Class 72. In
the "SEARCH CLASS" notes for the subclasses indented
hereunder, reference to the (4) Note indicated that the other
class and subclass should be considered because the control
system, per se, of a patent in the other class may be similar
to a control system, per se, of Class 72. The notes to Class
83, subclass 399, summarize all the subclasses in Class 83
pertaining to "control" subclasses therein.

detecting means to discern multiple characteristics; in
either case, then comparing the characteristics and

or differences between the detected characteristics, whereby

including using a contoured guide engaged by a traversing

(1) Note. The term "pattern" (in the title) refers to a
model or prototype insertable into and removable from the
machine and having a shape or configuration exactly similar
or proportional to the shape or configuration of the desired
product. A cam or eccentric or other object which is
distorted with respect to the desired product is not
considered to be a pattern, and control disclosures of such
