DEFINITION

Classification: 83/385

(under subclass 375) Device, in which a tool or an element rigid therewith, during the tool stroke serves to impart motion to a cam, lever, linkage, or other force-transmitting means which drives the clamp.

(1) Note. The force-transmitting means in the definition of this subclass comprehends any mechanical or fluid pressure mechanism operatively interposed between tool or tool support and movable clamp jaw, including for example a simple pivoted

link connection, but excluding a direct driving abutment, for which see subclasses 383+.

(2) Note. A clamp which is moved away from closed (actuated) position by linkage driven by tool or tool support, and which is biased or driven toward closed position by other means will not be found here, but in subclass 375 (or subclasses 388+ for yieldable drive). Also see (2) Note, under subclass 388.
