DEFINITION

Classification: 254/272

With cable deflecting or path defining component shifted by cable when tension varies:

(under subclass 270) Apparatus wherein the mechanism has a cable-contacting component which either (a) slightly deflects a segment of the cable from the linear direction of adjacent segments or (b) defines a portion of the path of travel of a segment of the cable contacted by and moving relative to it, the component is shifted by the cable when the tension on the cable is varied and generates the regulating force to the rotation-retarding means or the drive when shifted.
