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. Since the jaws are not positively attached to one another, the jaws can be expanded to accommodate work pieces of widely varying thicknesses.
