DEFINITION

Classification: 83/388

(under subclass 375) Device wherein the clamp-actuating means comprises a force-responsive (i.e., resilient or slipping) element forming part of the force-transmitting train which moves the clamp toward its applied condition, such element serving to limit the force which can be exerted on and by the movable clamp jaw.

(1) Note. The yieldable element may be a mere overload responsive means, not effective during normal conditions of operation. See (2) Note and (3) Note under subclass 386, supra.

(2) Note. A clamp which is continually biased toward closed position, but is raised cyclically by power-driven linkage will be found in this subclass, even though the linkage is moved by a tool or tool support. But see subclasses 383 and 385+ for a clamp biased toward open position and driven toward actuated position, directly or through linkage, by the tool support.
