ABSTRACT:
A fluid driven piston and cylinder includes a pair of wide opening jaws for gripping relatively thick workpieces. The jaws are mounted on a head which is linearly displaceable by a piston rod powered by the piston and cylinder. An actuating plate on the head actuates closure of the jaws when the head reaches its maximum outward position of displacement. The actuating plate displaces a U-shaped yoke reciprocably mounted on the head. The jaws are pivotally mounted on the head and are squeezed into gripping relationship to a workpiece by rollers mounted on the extremities of the yoke.
