ABSTRACT:
A device for clamping a rod to stop axial and/or rotative movement between the rod and the device. The device includes pressure and clamp units, the clamp unit having a bushing fixed therein and provided with a radially resilient center section normally sized to permit movement of the rod therein. The pressure unit has an actuating piston normally held under fluid pressure in one position but movable under spring pressure toward a second position should the fluid pressure be lost or released. Such movement results in the application of pressure to the bushing to radially deflect its center section inwardly into clamping engagement with the rod to stop its movement. The center section remains clamped on the rod until sufficient fluid pressure is applied to the actuating piston to move it back to its first position thus permitting radial expansion of the center section to release the rod for movement.
