  • Patent number: 5791323
    Abstract: A pulley assembly for a compound bow is provided with a take-up of spool configuration to receive a segment of a tensionable bow member wound thereabout. The take-up is engageable with the pulley proper member in a manner preventing relative movement between take-up and pulley assembly. To alter length of a tensionable member of the bow, the take-up is positionable about an axis parallel to an axis of the pulley assembly and lockable thereto. Modified forms of the take-up disclose various locking arrangements.

  • Patent number: 5322049
    Abstract: A tensionable member is disclosed for installation on an archery bow as a bowstring or a cable of a compound bow. The tensionable member has an outer tubular component of braided construction and a core of multiple strands. A suitable material is polyethylene fiber for use in both the tubular outer member and the core. End loops are formed on the tensionable member by reversing the ends of same and inserting the ends back into the tubular member. A locking element passes transversely through the reversed and inserted end segment and through the tubular outer member to retain the loop configuration. A modified form of tensionable member includes provision for retention of a sight and includes a sight retainer member having its ends secured within the tubular outer member by locking elements passing therethrough. The locking elements are of a fusible material to facilitate securement.
