DEFINITION

Classification: 83/409

(under subclass 401) Device in which the work-moving means includes elements or mechanism (mounted on or integral with, and moving with, said means) for securing the work against both forward and rearward shifting of the work relative to the motion of said work-moving means, whereby the work partakes of all the feeding movements of the work mover.

(1) Note. In this and indented subclasses, the combined work-mover and work-constraining means will be referred to as a "work carrier".

(2) Note. A feed drum with radial projections thereon (commonly known as a "pinwheel") is not considered as a work carrier as defined above if the work enters the pinwheel chorally or tangentially, contacts only part of the periphery of the pinwheel, and leaves the pinwheel chordally or tangentially. For patents directed to such feed means, see subclass 423.

435.11+, for a cutting device having a rectilinearly moving work carriage and tool adapted to cut parallel to the direction of and during work movement. 437.1+, for a cutting device having a rectilinearly moving work carriage and a tool, generally.

730, for a cutting device including a rectilinearly moving work carriage and including means to cause the cutting device to make plural passes through a diminishing workpiece, including means to effect incremental movement toward the plane of cut.
