ABSTRACT:
An archery bow is disclosed of the type having force multiplying rotary devices mounted to each tip of the limbs of the bow member, which act to reduce the required bowstring draw force at full draw. Each of the rotary devices are comprised of three rotary elements mounted for rotation about a common axis, a first element connected to the bowstring, and second and third elements connected to a pair of load cables so as to be in opposition to each other, and with one of the second or third elements able to exert a greater leverage about the common axis. This arrangement causes longitudinal bending of the limbs upon drawing of the bowstring, with the bending of the limbs equalized by the action of the load cables in being connected to each of the rotary devices. The load cables are routed along the handle section to be out of the way in the central region of the bowstring. The configuration of each of the rotary elements provides a variable leverage force to reduce the draw force as the bowstring reaches maximum draw.
