  • Patent number: 4458657
    Abstract: A compound archery bow has a main frame with a pair of rigid arms extending outwardly from a central handle portion. A cam member is rotatably journaled on the end of each arm and a bowstring is connectable between the cam members. A resilient member, preferably a pair of rubber tubes, interconnects the main frame and each cam member at a point offset from its axis. When the cam rotates as the bowstring is drawn, the point of attachment of the resilient member to the cam member is brought into general alignment with the cam axle and the point of attachment of the resilient member to the main frame. Forces generated on the cam member by the resilient member at full draw are thus substantially radial. Both points of attachment of the resilient members are adjustable, and the applied tension of the resilient members is adjustable as well. A pulley is rigidly connected to each cam member, and the pulleys are interconnected by a cable to cause both cam members to rotate correspondingly.
