Abstract
A pulley assembly for a compound archery bow comprises an axle, a draw cable pulley, and a pair of split-buss let-out pulleys positioned on opposite sides of the draw cable pulley. Each secondary cable of a split-buss end of a power cable is wound in a spiral arrangement around a corresponding split-buss let-out pulley. As the bow is drawn, the pulley assembly rotates, the draw cable pulley lets out a draw cable, and each split-buss let-out pulley lets out the corresponding secondary cable. The spiral arrangement results in lateral movement, away from the draw cable pulley, of a contact point of the corresponding secondary power cable on each split-buss let-out pulley as the bow is drawn. The spiral arrangement can include a corresponding spiral groove on each split-buss let-out pulley.
