.~ With means to control magnitude of work-feed increment or work acceleration {2}
265
.~.~ Full stroke required of feed means
DEFINITION
Classification: 83/265
(under subclass 263) Device including means to prevent reversal of direction of work-feed means before it has completed a predetermined travel.
(1) Note. The full stroke mechanism is frequently interlocked with the tool actuating means to prevent premature tool actuation; patents claiming the interlocking feature are originally classified in subclass 221.
(2) Note. In addition to its primary function of preventing underfeed of work, full stroke mechanism also prevents the advance of an excessive amount of work by repeated actuation of the work-feed means through partial strokes between successive tool strokes.

221, for interlock between work-feed and tool actuation, and see (1) Note above. 222, for tool actuation tripped by completion of work-feed and vice versa.
360+, for operation controlled by means responsive to work.
