  • Patent number: 4770154
    Abstract: A compound bow (20) with a moment transfer pulley system (28) for reducing the holding force at the maximum bowstring draw position and for attaining and maintaining a high amount of stored energy. The moment transfer pulley system includes a pulley assembly (38) having a primary axle hole (76) and a primary axle (44) upon which the pulley assembly rotates. A secondary axle (64) is mounted to the pulley assembly. Mounted on the bow limb tip (24) on opposite sides of the pulley assembly are two moment transfer cams (52 and 54). These transfer cams are held in fixed relationship to the limb 24. The transfer cams include a notch (78) for receiving the secondary axle (64). As the bow reaches the full draw position the secondary axle (64) is received into the notches (78).
