DEFINITION

Classification: 83/58

(under the class definition) Device provided with means capable of bringing any or all of the moving parts of the device to a halt, such means acting to accomplish its halting effect 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 the 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 disrupt the flow of power to a part or all of the machine, as by effecting the disconnection of the parts of a clutch.

(2) Note. It is not a bar to original placement of a patent in this subclass, that the claimed power train disrupting, braking 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.

(3) Note. If, however, the normal and intended operation of power disrupting, friction gripping, or other motion preventing means, is to forestall the impending start of movement or activation of a part of the device, then the

motion preventing means is regarded as an interlock and its claimed combination with an instrumentality of a cutting machine is found in subclasses 399+, below.

(4) Note. If the normal and intended operation of power disrupting means is to forestall or prevent future movement of a tool or tool support by disrupting its power-transmitting connection to an uninterruptedly moving tool-actuating mechanism, the claimed combination of the power-disrupting means with the tool support and tool actuating mechanism is found in subclasses 572+, indented under subclass 571 in this schedule.

SEE OR SEARCH THIS CLASS, SUBCLASS: 57, for manually caused disturbance (i.e., temporary change) of cyclic operation.

69, for stopping means effective on completion of a predetermined number of cutting cycles.

70, for delayed stopping after cessation of cyclic operation.

571+, for devices which disables a tool without bringing to a halt any moving part other than the tool or its support; see (4) Note above.
