ABSTRACT:
A compound bow includes a handle portion and appended limbs, eccentric wheel assemblies mounted to each bow limb, and a cable attached at its ends to the bow limbs and extending over the wheel assemblies. Each wheel assembly includes a bowstring wheel having a peripheral groove, a first take-up wheel having a peripheral groove, and a central passageway communicating between the grooves to permit attachment of the bow cable. A second take-up wheel is secured to the bowstring wheel and includes a peripheral groove which is aligned with the groove of the first take-up wheel. The take-up wheels are configured such that the cable is not received in the groove of the second take-up wheel when the bow is in the relaxed condition, but is so received when the bowstring is drawn. The draw characteristics of the bow are therefore changeable by substituting various shapes of the second take-up wheel, and such substitution may be readily accomplished without requiring that the bow be dismantled or unstrung.
