  • Patent number: 11839959
    Abstract: Provided is a clamp that can be attached to a tripod or other piece of equipment and which can hold rails for firearms, sights, scopes, parts, and the like, therein. The clamp is self-adjusting due to a compressible cam lever that enables an amount of give or play when clamping onto a rail or other object. The clamp also includes a scroll gear assembly that enables the compressible cam lever to drive opposing jaw plates toward and away from each other thereby clamping and releasing rails and other objects.

  • Patent number: 5076090
    Abstract: An apparatus for providing a reciprocating motion. The apparatus has a housing block that contains twin piston guides in spaced apart relationship to one another. The piston guides each contain a piston that has a gear rack. The gear racks are connected by a pinion gear so that the movement of one piston will cause an equal and opposite movement of the other piston. The movement of the pistons is controlled by the application of a fluid pressure to one or both of the pistons. The travel of the pistons is limited by a mechanical stop at one end and a fluid cushion device at the other end. Tools for the altering of a workpiece may be attached to one or both ends of the pistons. In one embodiment, the apparatus is subjected to a rotary displacement achieved through the linear motion of one of the pistons.

  • Patent number: 4743002
    Abstract: An improved mechanism for automatically clamping a die tool to a press bed or press ram. The automatic die clamp is self-locking and self-compensating to provide a failsafe operation in the clamped position and thus the mechanism retains the clamp in the clamped position. A ramp is provided to guide the movement of a wedge which wedge movement controls the movement of a clamping member. A spring bias may be provided as an optional feature to assist in the self-locking. Release of the clamp requires the application of an external force to overcome the locking of the teeth.

    Abstract: A racket stringing machine comprises a support frame, a tension head assembly, a lateral clamp head and a longitudinal clamp head. Movement of the tension head assembly is controlled by a brake motor which is controlled by the signals transferred from a limit switch. The limit switch is normally pressed by a contact element and released when a string clamp head pivoted on the tension head assembly is spring biassed to pivot away from the clamping frame and a contact element fixed on the string clamp head is separated from the limit switch. The lateral clamp head comprises two lateral clamp arms for clamping the lateral sides of a racket frame to be strung by a pivotal movement accomplished by an actuating block sliding along a rotating bolt. The longitudinal clamp head comprises a clamping sheet with a rack extending downward from the bottom surface for meshing with a sector gear so as to be rotated by a handle in order to clamp the upper surface of the racket frame.
