Abstract:
1. A compound archery bow that includes: a bow handle having projecting limbs, a first pulley mounted on a first of said limbs for rotation around a first axis, a second pulley mounted on a second of said limbs for rotation around a second axis, bow cable means including a bowstring cable extending from a bowstring anchor through a bowstring let-out groove on said first pulley and then toward said second pulley, a first power cable extending from a first power cable anchor toward said second pulley, and a second power cable extending from said second pulley through power cable take-up means to a second power cable anchor on said first pulley, such that draw of said bowstring cable away from said handle lets out bowstring cable from said bowstring let-out groove, rotates said first pulley around said first axis, and takes up said second power cable into said power cable take-up means on said first pulley, and a set of at least first and second non-identical bowstring cable draw length adjustment modules for alternate mounting on said first pulley to adjust draw length of said bowstring cable away from said handle, each of said modules including a first portion for mounting adjacent to said first axis, an intermediate portion that includes a power cable take-up groove that constitutes at least part of said power cable take-up means, and a heel portion spaced from said first axis and adjacent to said second power cable anchor when the module is mounted on said first pulley, such that said power cable take-up groove extends around said heel portion to a position adjacent to said power cable anchor, wherein a heel portion on said first module is larger than a heel portion on said second module to enable adjustment of power cable length when changing said modules by taking up slack in the power cables instead of haying to change the power cables.
