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.
In a compound archery bow having a handle, first and second limbs each having a first end connected to said handle and a pulley rotatable on an axle connected to a second end of each limb, a first cable for connecting the first limb to the pulley at the end of the second limb, a second cable for connecting the second limb to the pulley on the end of said first limb, and a bowstring interconnecting the pulleys, the improvement comprising:
Adjustable anchor means for connecting a cable to the end of a limb of a compound archery bow having a pulley mounted on an axle near the end of said limb comprising:
