Abstract
A pulley assembly for use in an archery bow includes an axle journal which defines a pivot axis about which a pulley body can rotate. The pulley body includes a first, a second and a third groove defined therein. Each groove defines a curve which extends at least partway around the pivot axis. The first groove is a bow string groove operative to receive a portion of a bow string. The second groove is operative to receive a portion of a first bow cable section and the third groove is operative to receive a portion of a second bow cable section. The pulley assembly is incorporated into a compound bow, and when the bow string is unwound from the first groove, a portion of the first bow cable section is wound into the second groove and a portion of a second bow cable section is wound into the third groove. Also disclosed are compound bow configurations incorporating the pulley assembly.
