ABSTRACT:
A hand-operated lever linkage control suitable for use as a motorcycle clutch control, comprising a housing attached to a vehicle, a lever assembly pivotally mounted in the housing and connected to a control linkage and a spring-tensioned pivoting eccentric arrangement in the housing and connected to the lever assembly for mechanically assisting lever travel during actuation of the control linkage. This spring-tensioned pivoting eccentric arrangement includes a pair of fulcrum pivots rotatably mounted in opposing sides of the housing forward of the lever assembly, a rigid member eccentrically mounted between the fulcrum pivots and rotatable therewith, rigid linkage arms connecting this rigid member to the lever assembly and a coil spring tensioned between the housing and the rigid member for urging pivotal movement of this eccentric assembly and for providing a mechanical advantage through the linkage arms to assist lever travel during actuation of the control linkage.
