Patent ID: 7578289

Claim:
A compound archery bow comprising: a riser supporting a member for gripping the bow; first and second limbs each extending in a forward direction from the riser to a distal end spaced apart from the riser; pulley means disposed adjacent to the distal end of each limb; a first cam and a second cam mounted with respect to the riser and rotatable on respective axes of rotation; a bowstring extending between the pulley means on each limb so that the bowstring may be drawn on a path between a forward position and a rearward position; one end of the bowstring extending from the pulley means on the first limb to the first cam, and another end of the bowstring extending from the pulley means on the second limb to the second cam; a first cable extending from the first cam to the pulley means on the first limb, and thence extending to the second limb; and a second cable extending from the second cam to the pulley means on the second limb, and thence extending to the first limb, whereby drawing the bowstring toward the rearward position rotates the cams and thereby causes the cables to wind onto the cams and compress the limbs, producing limb tension that acts through the cams and pulley means to propel an arrow from the bow when the bowstring is released.
