Compound archery bow with eccentric cam elements

Abstract

An archery bow includes a pair of bow limbs projecting from opposite ends of a handle member, each eccentrically mounting pivotal cam members at its outer extremity. Each cam member comprises a larger diameter cylindrical cam element and a smaller diameter cylindrical cam element eccentrically joined together and having a common pivot axis which is eccentric with respect to both cam elements. A bow string for projecting an arrow comprises a working stretch and a pair of separate end segments, one detachably connected to each end of the working stretch. Each end segment extends from the working stretch and is wrapped partially around its associated larger diameter cam element, then passes through a diametric bore in the cam member to the opposite side of the smaller diameter cam element, wrapping further around the smaller diameter cam element, and extending therefrom to a connection with the opposite bow limb.
