Abstract
A jaw is secured to a stem member having a T-shaped slot through which a pair of spaced pins pass. When the jaw and member are displaced from a clamp position to a neutral position, one of the pins is aligned with the T portion of the slot and the other pin is seated at one end of the main slot. The member tilts automatically to a retracted state in response to a spring force in a given direction. When the member is rotated from the retracted state to the neutral position the same spring force slides the jaw into the clamp position. A resilient projection on the stem member automatically engages a workpiece when the member reaches the neutral position to locate the workpiece prior to clamping.
