Patent number: 7273575Abstract: A composite riser for an archery bow formed from fibers embedded in resin in such a way that resin rich areas, dry fibers and voids are eliminated, providing consistent risers of high quality. The location of structural fibers, such as a carbon fibers or fiberglass composite materials, is ensured within a mold used to form the riser and relative to the resin which bonds the fibers together. Various processes may be used to form the riser with control of the fibers and resin maintained. For example, structural reaction injection molding, liquid composite molding, continuous fiber molding, modified compression molding, resin transfer molding and variable infusion molding processes can be used.Type: GrantFiled: December 1, 2003Date of Patent: September 25, 2007Assignee: SpencoInventors: Albert A Andrews, Spencer Land

Patent number: 6722354Abstract: 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.Type: GrantFiled: June 11, 2002Date of Patent: April 20, 2004Assignee: SpencoInventor: Spencer D.

Patent number: 6684870Abstract: 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.Type: GrantFiled: April 3, 2002Date of Patent: February 3, 2004Assignee: SpencoInventor: Spencer D. Land

Patent number: 6543432Abstract: 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.Type: GrantFiled: December 21, 2000Date of Patent: April 8, 2003Assignee: SpencoInventors: Albert A.
