ABSTRACT:
A compound archery bow is provided with a power cable system in which two pairs of parallel, laterally spaced power cable stretch segments extend parallel to and symmetrical with respect to the operating plane of a bowstring extending between eccentric cams mounted on the outer ends of bow limbs by cam shafts. One end of each of the parallel power cable stretch segments of each pair is connected to a single cable end segment. The free end of each end segment is secured to a different one of the eccentric cams and the free ends of the associated pair of stretch segments are connected to spaced apart positions on the shaft that mounts the cam opposite the cam to which the associated single cable end segment is secured. The stretch segments are held in spaced apart arrangement either by a spreader pin adjacent each of the opposite ends of the stretch segments, or by a pair of elongated cable guard rods projecting rearwardly from the bow handle and spaced apart to opposite lateral sides of the operating plane of the bowstring.
