DEFINITION

Classification: 72/318

Deforming indeterminate-length work:

(under subclass 316) Subject matter utilizing structure adapted to hold or present to the action of a metal-deforming instrumentality a portion of a workpiece of unrestricted length.

(1) Note. Typical apparatus of this subclass employs a reciprocatory heading punch to upset the projecting end of a rod or wire which is fed from the rear into a pair of opposed gripping jaws. (A bolt or nail header also usually comprises cutoff means which, if claimed, would place the combination originally in preceding subclass 294).

(2) Note. Any claimed deformation of work by the closing of the "gripping jaws" prior to or concurrently with the action of the heading punch, is evidence that the "jaws" are actually part of a tool complex*, for placement in subclasses 353.2+ or subclasses 394+.

SEE OR SEARCH THIS CLASS, SUBCLASS:

293+, for similar apparatus wherein the work-holding means

constitutes a nondeforming clamp.

353.2+, for deformation of work by a closed die tool complex* wherein two or more tools coact to grip partially deformed work for further treatment by a third tool.

357, for actuated split die and coacting closed die.
