Abstract: The present invention provides a clamp which can be used to secure an accessory member to an abductor bar of an orthopedic-surgical table. The clamp includes a clamp block pivotally mounted on the clamp and oriented with respect to the clamp to clamp an object therebetween. A lever having a cam surface is mounted on the clamp so that the cam surface coacts with the internal mechanism of the clamp to orient the clamp block in an unclamped, intermediate and clamped position. When the clamp is in the intermediate position, the clamp loosely engages the clamped object so that relative motion of the clamp and clamped object can occur. Because the clamp can be stabilized on the clamped object by orienting it in the intermediate position the operator does not need to use a second hand to prevent the clamp from falling off the clamped object while the first hand positions and tightens the clamp. Thus, the clamp can be secured to the clamped object in a one handed operation.

Abstract: A rotatable lever and an initially transversely disposed adjustable linkage echanism for attachment in predetermined relation to at least one movable work-performing arm and operable such that upon rotation of the lever and linkage mechanism responsive to pivotal rotary movement of the lever portion thru a designated travel arc of at least approximately 90.degree., the movable arm moves much more rapidly during the first approximate one-half to three-quarters of its designated travel arc, and thereafter continues to move progressively slower in a firm positive manner thru the remainder of the travel arc, while moving from its transverse relationship to a generally parallel or linearly aligned relationship. This simplified mechanism is non-servo in character and relatively low cost compared to servo devices embodying continuous sensing and feedback circuitry. Among various uses are easy association with various known industrial type robot devices embodying programmed control of articulated mechanical arms.
