DEFINITION
Classification: 72/313
Jaw actuator driven by tool or tool holder:
(under subclass 312) Subject matter wherein said movable instrumentality or means rigid therewith is arranged to transmit actuating force to move one or more clamp jaws or surface elements to effective (i.e., work-gripping) position.
(1) Note. In a device of this type, the movable clamp jaw may be yieldably mounted on the tool holder or press ram and arranged to engage the work in advance of the moving tool.
(2) Note. Metal drawing presses frequently employ a work clamp or "blank- holder" which is actuated by the tool slide or press ram. Such an arrangement is proper subject matter for this subclass, provided there is no disclosure of work slipping or deformation in the blank holder; cf., (2) and (3) Notes under subclass 300.
