DEFINITION

Classification: 408/122

(under subclass 121) Device including provision to allow the locking means to be operative to transmit torque selectively in either direction (and correspondingly to be inoperative in the respective opposite direction).

(1) Note. A ratchet device that is simply turned over to reverse the output is not considered proper for this subclass.
