ABSTRACT:
A compound bow that uses mechanical advantage for interconnecting the bowstring with the resilient bow limbs is configured in such a way that all components of the mechanical advantage are positioned to lie outside the immediate vicinity of the arrow position, thereby permitting the bowstring to be aligned with the centerline of the limbs and further permitting all vector forces operating on the bowstring, limbs, and mechanical advantage to lie in a common plane, thus minimizing twisting torques applied to the limbs. In an embodiment comprising cables attached to cams as part of the mechanical advantage, the use of rotating cable-end fasteners minimizes the friction from cable flexing.
