Abstract
An apparatus and a method are disclosed for varying the effective length of the levers which actute a collector ring in a clutch. Each of the levers includes a pair of noses which are angled toward the inner end of the levers and toward the collector ring to provide a point contact which moves along the surface of the nose as the levers are rotated by a throw-out bearing. Thus, the force required to actuate the throw-out bearing and/or the force applied to a pressure plate can be varied in accordance with the geometry selected for the noses and the collector ring.
