  • Patent number: 6722354
    Abstract: An archery bow has a cable guard with at least one guide pulley rotatably carried by the cable guard to receive at least one harness string portion and maintain the harness string portion out of a user's way while using the bow. The archery bow has a body or riser with a handle portion and a pair of limbs each having a free end spaced from the handle portion. A separate pulley is rotatably carried adjacent the free ends of each limb and at least one string is trained around the pulleys and has a draw string portion and at least one harness string portion. The harness string portion is trained around at least a portion of a guide pulley, and if more than one harness string portion is provided, then each harness string portion may be trained around a separate guide pulley to maintain the harness string portions separate from each other and to maintain each harness string portion in a laterally spaced relation from the drawstring portion.

  • Patent number: 6684870
    Abstract: An archery bow has a pair of limbs with at least one of the limbs having a split section defining a pair of limb sections generally separate from each other. A connecting member is received within the split section to connect the limb sections to each other between a point of string attachment and a handle portion of the bow. The connecting member limits relative movement between the limb sections.

  • Patent number: 6543432
    Abstract: An archery bow has at least one dampener to reduce noise and vibration of the bow in use. Desirably, at least one dampener, and preferably a plurality of individual dampeners may be disposed in the area of the connection of a limb to a riser or handle portion of the bow to reduce vibrations transferred to the riser by the limb. Additionally, the archery bow preferably has a cam adapted to receive a dampener to reduce the noise and vibration passing between the cam and the limb. Any number of dampeners may be used in combination, or the dampeners may be used separately as desired.

  • Patent number: 6082346
    Abstract: A compound bow having a pair of cam modules or secondary cams with at least one cam module having a draw stop integral therewith to engage a harness string of the compound bow at the optimum draw length of the bowstring to prevent this optimum draw length from being exceeded and to efficiently and repeatably store the same quantity of energy in the compound bow. The integral draw stop decreases vibration of the bow in use and cannot be moved to thereby insure that the optimum draw length can be readily achieved throughout the life of the bow. A floor or post is also preferably provided on each cam module to firmly hold and retain one end of a harness string.
