DEFINITION

Classification: 474/19

Via relatively rotating cam and follower:

(under subclass 17) Subject matter wherein the means responsive to the sensed resistance or change of resistance to movement includes relatively rotating elements having actuating surfaces in rolling or sliding engagement with each other, said actuating surfaces being so contoured with respect to each other, and so associated with respect to one of said belt*-engaging components that relative rotation between such actuating surfaces is converted into axial movement of one of said belt-engaging components.
