Abstract: A quick clamping fixture includes a main rod, on which two sliders are slidably mounted and may be braked at desired positions to clamp a workpiece between them. The two sliders each have an L-shaped plate and a set of metal plates mounted in a housing thereof with the main rod extended through these plates. The L-shaped plate and the metal plates in the housing are normally pushed by a compression spring into an inclined state to thereby firmly press against an outer surface of the main rod, preventing the slider from sliding along the main rod. When the L-shaped plate is pushed and held, the L-shaped plate and the metal plates are moved into an upright state without firmly pressing against the main rod, allowing the slider to slide along the main rod; and when the L-shaped plate is released, the slider is braked again.

Abstract: A cam actuating clamp. The clamp has first and second jaws, with one of the jaws including a surface forming a fulcrum and the other one of the jaws including a projecting arm which contacts the fulcrum when the clamp is in an open position. The clamp is moved from a closed to an open position simply by the user grasping an actuating lever that is pivotally secured to one of the jaws and lifting the clamp, in which the weight of the jaws causes rotation of the jaws, relative to the actuating lever, into an open configuration. A pair of springs secured under tension between the jaws hold the jaws in the open position. The jaws are clamped over a work piece by the user moving the actuating lever into a second position. A camming surface on the actuating lever provides an over center action that enables the springs to both assist in opening the clamp as well as closing the clamp depending upon the position of the actuating lever.

Abstract: An improved bar clamp in which the first jaw assembly consists of a handle assembly or setting unit, on a slide bar inside of an independently mounted first jaw. A finger lever is pivotably attached to the setting unit and at its upper end pivotably attached to the first jaw. A braking lever is included in the first jaw, and a driving lever in the setting unit. Upon first movement of the finger lever a spring forces the driving lever into firm contact with the slide bar, preventing movement of the first jaw away from the second jaw. The finger lever has no further contact with the driving lever, but upon further movement, acts indirectly on the driving lever via the handle assembly to draw the slide bar and the second jaw towards the first jaw. Releasing the finger lever draws the handle unit forward for the next cycle. Release of the braking lever in the first jaw allows movement away from the second jaw.
