DEFINITION

Classification: 474/21

Including plural separate cam and follower pairs for adjusting plural members:

(under subclass 19) Subject matter including an additional pair of relatively rotating elements having actuating surfaces in rolling or sliding engagement with each other, the additional pair of actuating surfaces being so contoured with respect to each other, and so associated with respect to an additional belt*-engaging component that relative rotation between such additional pair of actuating surfaces is converted into axial movement of the additional belt-engaging component.
