DEFINITION

Classification: 72/297

With means to actuate tool:

(under subclass 296) Subject matter utilizing a power-transmitting element effective to drive said further instrumentality during an operation of the class type.

(1) Note. When the coacting tool is an actuated member, as in this subclass, the work-gripping clamps may be either driven or passive members, but in any case they must be capable of relative motion with respect to each other (e.g., they may be independently pivotally mounted).
