DEFINITION

Classification: 83/714

(under subclass 713) Device wherein the means for moving the work perpendicularly toward the cutting plane retracts the work from said plane after the cutting operation has been performed.

(1) Note. The alternate to-and-fro shifting of the work is for the purpose of aligning the work with the cutting plane prior to each cut and then clearing the work from the plane as it is reciprocated back to prepare for a subsequent pass or cut.

(2) Note. The means to move the work toward and away from the cutting plane must be structural. For devices wherein the transverse work-advancing means is moved manually, see subclass 713.

724, for a similar device wherein a work retraction means is provided in addition to the means to move the work toward the cutting plane.
