ABSTRACT:
A compound bow utilizes tension cables and bowstring cables acting on grooved cam pulley assemblies. The tension cables are not connected to the bowstring cables at the pulley assemblies but rather are separated at the pulleys and each separate end is formed as a loop. An attachment knob is formed integrally within the confines of the pulley and is provided with a re-entrant notch to provide a retainer attachment for the looped ends of a bowstring cable. A similar attachment can be provided for the ends of the tension cables. The concept may also be used to adjust draw length or tuning of the wheel timing as effected by the cable length by providing more than one knob spaced to allow shifting a looped end from one knob to another. The knobs with appropriate notches for the tension cables face in a direction opposite to those which receive the loop of the bowstring cable.
