(under subclass 202) Device in whose operation the work is caused to undergo more than one advancement and stoppage for each stroke of tool, or is advanced successively by different

feed means during one tool cycle.

SEE OR SEARCH THIS CLASS, SUBCLASS:

111+, for means to clear the freshly-cut edge of product (cut work) from a tool, by moving it relative to the tool, prior to the next work-feed increment, thereby in effect affording a plurality of increments between successive tool strokes.

206, for a work-moving clamp, which follows and supplements an approximate work-feed by hand or mechanical means.

207, for an actuated abutment which can move work to a final position after a preliminary feed of work against the abutment.

219+, for a machine wherein the work may be caused to move in different directions between successive tool strokes. 228, for supplemental work-feed means mounted on tool or tool support.

234, for means to vary the number of work-feed increments between strokes.

280+, for means to move work into the effective range of work-feed means proper, and see (4) Note under subclass 251 for the distinction between supplemental work-feed means and work transport means.
