  • Enhancer for compound bows
    Patent number: 6532945
    Abstract: An enhancer assembly for connection to a compound bow by means of a bracket that mounts the enhancer assembly to the compound bow at a position proximate to the cables in a position off-set from the bowstring to retain the cables from being in the path of the bowstring. The enhancer assembly comprises an enhancer composed of a non-metal material and at least one cable guide connected to one end of the enhancer for slidably receiving the cables, whereby the enhancer reduces the amount of shock and noise produced upon release of the drawn bowstring to propel an arrow and increase the speed of the arrow.

  • Cluster sprockets for bicycle transmissions and other prime movers
    Patent number: 6293884
    Abstract: This invention comprises a multi-sprocket or cluster gear assembly with a plurality of progressively sized sprockets or gears that are positioned adjacent to each other so as to define an increasing diameter sprocket assembly. Each sprocket comprises a non-circular configuration having at least one long dedendum radius and at least one short dedendum radius, such as an eccentric oval shape. The short radius and the long radius of two adjacent sprockets are aligned and substantially equal in length with each other. The teeth of the sprockets may comprise a chamfer face to better facilitate derailing from one sprocket to the adjacent sprocket. The axial alignment of one sprocket may be retarded by one tooth, relative to the axial alignment of the larger sprocket to better facilitate derailing.
