DEFINITION

Classification: 72/299

About axis intersecting work-gripping regions of two clamps (e.g., twisting):

(under subclass 298) Subject matter wherein said pivot line extends directly between the opposed jaws or surface elements of the work-gripping instrumentalities.

(1) Note. This subclass generally relates to twisting a gripped rod or bar along its axis, for examples of "offset" twisting or "warping", see subclass 298 and subclass 295 above. For similar operations involving axially moving work, see subclasses 64+ above.

SEE OR SEARCH THIS CLASS, SUBCLASS:

64+, for twisting axially moving work.

127+, for deflecting bodily moving work.

371, for a coiling or twisting method.

381+, for an offset-face-tool complex capable of twisting work (e.g., a crankshaft).
