DEFINITION

Classification: 83/355

(under subclass 350) Device including means which constantly transmits power to actuate the tool continuously through repeated strokes during continued movement of the work.

(1) Note. A cam-driven tool would satisfy the limitations of the definition of this subclass only if no dwell period occurs during the camming cycle. (A dwell period implies interruption in the flow of power to the tool).

(2) Note. Examples of tool actuation to be found in this subclass are (a) simple rotation, (b) tools driven with sample pendulum motion, (c) reciprocating tools driven in substantially simple harmonic motion, as by a Scotch yoke, an eccentric, or a conventional rotary crank and connecting rod.

SEE OR SEARCH THIS CLASS, SUBCLASS:

315+, 318+, and 321+, for a tool which is actuated in an oscillatory manner so as to operate on moving work while periodically moving along with the work (flying cutter).

331+, for a rotary cutter arranged to travel with moving work during the cutting operation (flying cutter).

591+, for a tool having simple rotary motion throughout its stroke or cutting cycle.
