Compound archery bow
DCFirst Claim
1. A compound archery bow that includes:
- a 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, andbow cable means including a bowstring cable extending from bowstring let-out grooves on said first and second pulleys,a first cable extending from a cable take-up groove on said first pulley to second cable let-out means on said second pulley, anda second cable extending from a cable take-up groove in said second pulley to first cable let-out means on said first pulleysuch that draw of said bowstring cable away from said handle lets out bowstring cable from said let-out grooves on said first and second pulleys, rotates on said first and second pulleys around said axes, and lets out portions of said first and second cables from said first and second cable let-out means on said first and second pulleys,wherein at least one of said bowstring let-out grooves and/or at least one of said cable take-up grooves is non-circular.

Abstract
A compound archery bow includes a handle having projecting limbs. A first pulley is mounted for rotation around a first axis on a first of the limbs, and a second pulley is mounted for rotation around a second axis on a second of the limbs. A bow cable arrangement extends between the pulleys, and includes a bowstring cable extending from bowstring let-out grooves in the first and second pulleys so that, as the bowstring cable is drawn away from the handle, the bowstring cable lets out or unwraps from the bowstring grooves and rotates the pulleys around the respective axes. First and second cables extend from cable take-up grooves on the respective pulleys to first and second cable let-out means on the respective opposite pulleys. Thus, as the bowstring cable is drawn away from the handle, the first and second cables are each taken up or wound at one end onto one of the pulleys and let out or unwound at the other end from the other pulley.
