    摘要: A compound bow comprising a handle portion having a first limb and a second limb extending outwardly therefrom, a wide body cam assembly pivotally coupled to the first limb near an outer end thereof, and a dual wheel assembly pivotally coupled to the second limb near an outer end thereof. The wide body cam assembly comprises a main sheave and a collector sheave located on opposite sides of a cable sheave. The main sheave is spaced apart from the cable sheave by a first distance sufficient to permit arrows to be fired from the bow free from interference by a cable without the use of a cable guard. The dual wheel assembly comprises a feed out sheave and a take in sheave separated by a second distance which is larger than the first distance. The feed out sheave is positioned substantially within a plane defined by the main sheave.

    摘要: A cable guard eliminator for a compound bow comprising a first limb and a second limb and having a bowstring and at least one cable strung between first and second connecting elements respectively mounted near outer ends of the first and second limbs. The cable guard eliminator comprises a first portion from which the cable extends to the first connecting element, a second portion from which the cable extends to the second connecting element, and, an intermediate portion defining a deflection area between the first end and the second end. The deflection area has a length in a direction generally parallel to the cable at least as long as a range of motion of the cable, such that at least some portion of the deflection area remains aligned with an arrow path throughout drawing and release of the bowstring.

    摘要: The invention provides a portable bow press and a limb connector therefor, for use with a bow comprising a pair of resilient limbs that extend outwardly from a handle. The bow press is used to force the outer ends of the limbs together, thereby releasing tension on the bow string and/or cable. The user is then able to remove, replace or repair the bow string or cable while the bow press holds the bow in position. The bow press may comprise two limb connectors which hold the bow press in place. Each limb connector may comprise an outer peg and an inner peg, which are used to couple the limb connector to a bow limb.

    摘要: Apparatus for electroplating a workpiece includes an unassembled electroplating anode assembly having weldable first and second structural anode members. The first structural anode member includes a positioning slot. The second structural anode member includes a positioning tab disposable in the positioning slot. A method for making an electroplating anode assembly includes obtaining an electroplating-anode-assembly first structural anode member having a positioning slot and obtaining an electroplating-anode-assembly second structural anode member having a positioning tab. The method also includes locating the positioning tab in the positioning slot and welding together the first and second structural anode members.

    摘要: A telescopic boom includes at least two sections and a manual section is sections being extended and retracted by a single hydraulic ram. A first coupling selectively connects or releases the ram's cylinder case from the second boom section while a second coupling connects or releases the other end of the cylinder case to the manual section. The first coupling includes a crank for coupling and uncoupling the cylinder case and second section. The second coupling includes a retrieval pin movable into position for connecting the cylinder case to the manual section when retracting the manual section within the second section, and releasable lock mechanisms are provided to lock the manual section in extended position. The method of operating the boom includes the step of pivoting the boom to a near vertical position prior to extending the manual section relative to the second section.
