ABSTRACT:
A compound archery bow has an adjustable anchor in which a bracket having two arms is connected to the axle upon which the wheels rotate. The arms are interconnected by a translation mechanism for moveably locating the end of the cable along a path parallel to the axle. The translation mechanism is a cylindrical member having a helical groove in the outer surface thereof. The free end of the cable is looped over the cylindrical member and fastened to the cable. Rotating the cylindrical member causes the looped end of the cable to change position from side to side across the limb, permitting adjustment to minimize the net torque on the limb. Other embodiments of the translation mechanism include a pulley, parallel to the other pulleys, mounted on a threaded axle, or a threaded eyelet attached to the end of the cable and engaging a bolt connected to the two arms of the anchor bracket. A fixed anchor locates the cable at a predetermined position across the width of the limb to optimize the torques on the limbs for a given pair of wheels.
