DEFINITION

Classification: 234/22

(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+.
