ABSTRACT:
A powered clamp and gauging apparatus performs as a clamp with moveable members which generate a toggle action, or performs as a gauging device having a pair of moveable members which mechanically abuts against each other to maintain, at least temporarily, a locking position of an arm even when actuating fluid pressures have been decreased or lost. In another aspect of the present invention, a lost linear motion device is provided in order to maximize arm unlocking forces. A uniquely configured slide, crank and hub are provided in a further aspect of the present invention. Methods of operating and assembling the present invention apparatus are also provided.
