ABSTRACT:
A compound bow includes improved low-rotation cam members eccentrically mounted upon the bow limp tips and each provided with an enlarged main body section, a reduced width intermediate section and an elongated terminal section generally defining an irregular kidney-shaped profile. A single cable groove or track extends continuously around the entire periphery of each cam and is disposed in a single vertical plane such that any stretch of cable extending between the tracks of the two cams will be substantially aligned with the bow center line. A single continuous cable stretch, having its opposite ends respectively joined to a bowstring and a tension cable, is sheaved about the track of each cam and is adjustably anchored thereto by means of a removable, lockable, rotating keeper whereby fine adjustment of the bow may be achieved without disassembly or removal of any cable lengths from the bow cams. The improved cam members may be employed not only in two-wheel compound bows but also in four and six wheel models.
