Abstract: Compound bow having two eccentric wheels or cams at each end. One of the wheels may be quickly manually adjusted with respect to the other without disassembling the strung bow to adjust the magnitude of drop off at full draw without significantly changing the draw length or peak weight. Also, a ball and socket type quick connect and disconnect device is provided for dead ending the bow cables or strings to the eccentric wheels or cams.

Abstract: In a compound bow the eccentric wheel assemblies at the limb ends are cross-coupled by the bow stringing so that they are constrained to move in unison so that the bow is self-tuning. Each wheel assembly has three grooved wheels rotatable on a common axis. A first one of the wheels is eccentric and has one end of the bowstring connected to it. The other end of the bowstring is connected to a similar eccentric first wheel at the other end of the bow. A first cross-coupling stretch is connected between a second wheel at one end of the bow and a third wheel at the other end. A second cross-coupling stretch is connected between a third wheel at the one end and a second wheel at the other end.

Abstract: Pairs of individually changeable cam wheels at the tips of a compound bow for selective adjustment of the weight and draw length of the bow. The wheels have halves having different size grooves, said halves being interchangeable thus offering a full range of different weight and draw length bows.
