Compound archery bow
Abstract:
A compound archery bow includes a bow handle having projecting limbs, and first and second pulleys mounted on the limbs for rotation around respective axes. A bow cable arrangement includes a bowstring cable extending from a bowstring anchor through a bowstring let-out groove on the first pulley and then toward the second pulley. A first power cable extends from a first power cable anchor through a power cable let-out arrangement on the first pulley toward the second pulley, and a second power cable extends from the second pulley through a power cable take-up arrangement on the first pulley to a second power cable anchor on the first pulley. Draw of the bowstring cable away from the handle lets out bowstring cable from the bowstring let-out groove and rotates the first pulley around the first axis, lets out the first power cable from the power cable let-out arrangement on the first pulley and takes up the second power cable into the second power cable take-up arrangement on the first pulley. A power cable stop is disposed on the first pulley at a position to be engaged by the first power cable as the first pulley is so rotated to inhibit further rotation of the first pulley and thereby inhibit further draw of the bowstring cable.
