ABSTRACT:
A cable guide assembly for a compound bow is disclosed. The guide assembly includes a spindle having a central bore for receiving the bow mounted offset cable rod. A pair of cable rollers are rotatably retained upon the spindle to receive and guide the two runs of the tensioning cable. A plurality of stationary ball bearings are provided in the wall of the spindle to slidingly engage both the cable rod and the rollers to provide the low friction action. During operation of the bow, either during drawing or release, the limbs of the bow flex, imparting an orthogonal (up and down) as well as an axial (back and forth) motion to the tensioning cable. Advantageously, the rotating action of the rollers accomodates the up and down motion of the cable. Concurrently, the guide assembly freely slides upon the rod to accomodate the axial motion of the cable. Thus, the roller assembly allows free, unrestricted cable motion at all times, resulting in a truer, more accurate flight of the arrow, as well as increased hitting power.
