  • Patent number: 5516088
    Abstract: An improved carpenter's clamp is provided for easily securing a workpiece. The clamp has a C-shaped frame that can be mounted to a holding surface. The frame has a top and a bottom receiver aperture. A slide bar is slidably mounted in an axial direction within the top and bottom receiver apertures, and a handle is pivotally attached to the frame to provide a downward axial force to the slide bar when the handle is lowered. A toggle link is provided allowing the handle to be locked in a downward position thereby locking said slide bar in a secured position. A holding arm having a holding tip at a distal end is slidably mounted to the slide bar, and the slide bar is positioned between a pair of bias pins on the holding arm so that a workpiece can be held between the holding surface and the holding tip when a downward force is applied to the handle.
