Abstract
The invention is directed to a clamp for holding a workpiece to a work surface having an aperture formed therein. The clamp includes the main support arm having one end portion adapted for insertion into the aperture in the work surface. A clamping arm is pivotally connected to the main support arm above the above-mentioned end portion and the clamping arm defines a clamping surface for engaging the workpiece placed on the work surface. A first lever arm is pivotally connected to the main support arm and a second lever arm has one end pivotally connected to the first lever arm and another end pivotally connected to the clamping arm. Suitable structure is provided for applying a force to the pivot mutually connecting the first and second lever arms to cause the lever arms to transmit the respective forces to the main support arm and the clamping arm causing, in turn, the main support and the clamping arm to rotate with respect to each other so that the main support arm tightly engages the wall defining the aperture in the work surface and so that the clamping arm tightly engages the workpiece. The clamp also can be adapted to hold a workpiece to a workbench having no aperture therein. A clamping arrangement includes a member defining a work surface and having at least one aperture formed therein and the clamp. The clamp and member tightly hold the workpiece.
