ABSTRACT:
An archery bow design in which at least one flat wound power spring is mounted on a frame and is connected through an eccentric wheel or cam and a pulley system to a bow string so that the action of drawing back the bow string causes the coil spring to be wound up, storing energy. The eccentric wheel or cam and the pulley system provide a mechanical advantage whereby a relatively small force is required to draw the bow and wind up the power spring, and a relatively higher recoil velocity is obtained when the string is released.
