ABSTRACT:
The weight of a pivoted body is counterbalanced by a spring acting on a cam connected to that body to pivot therewith. A band, connected to that spring, attaches to the cam and wraps around the cam. The cam's profile is contoured to produce moment arms of various lengths, through which the force of the spring acts, balancing the variable torque of the weight of the pivoted body.
