ABSTRACT:
A clamp incorporating two opposed jaws having resilient pads affixed in way of their gripping surfaces. A first jaw is fixed on a pair of spaced slide rods. The slide rods are held by their being fixed in a clamp arm in a parallel relationship. A second clamp arm is received for slideable movement on the slide rods. A force applied between the slide rods, will cause the clamp arms to move together until they engage an object to be clamped. Further pressure will allow the desired clamping pressure to be achieved. When the pressure is released, the clamping pressure will be maintained by the frictional engagement between the bearing surfaces in the sliding clamp arm and the metal slide rods. Release is achieved by force on the sliding clamp arm in the direction opposite to that used to achieve clamping.
