Abstract
A clamping device including a pair of counter-opposing angularly shaped beams each having a forward jaw portion and a rearward portion interconnected by a pair of connecting straps and a force exerting element. Each connecting strap is pivotally attached at one end to a forward jaw portion of one beam and the rearward portion of the other beam. The point of intersection of the connecting straps moves progressively closer to the workpiece held between the jaws as the jaws are closed and exert simultaneously equal forces ont the workpiece. In one embodiment the clamping device is adapted for use as a portable tire bead breaker suitable for use on large truck or tractor tires.
