DEFINITION

Classification: 83/573

(under subclass 572) Apparatus wherein the force required for connecting or disconnecting the tool is supplied solely by a human operator.

(1) Note. The operator may act upon the gag through a linkage or other mechanical force modifier which introduces no other source of power. If, however, the claimed subject matter requires that the operator merely actuates a switch or clutch to connect some other source of power with the gag-moving means, the patent is not placed in this subclass, but in subclass 572.
