Abstract
A polished rod lock out clamp for use in securing the polished rod in an oil well installation, comprising a clamp body having a bore for receiving a polished rod in spaced relation to the bore; clamp members in the clamp body for engaging a polishe d rod in the bore; and radial bolts secured to the clamp body and the clamp members for moving the clamp members between a polished rod gripping position where the clamp membe rs grippingly engage the polished rod to prevent rotation and axial movement thereof and a retracted position where the clamp members are removed from the polished rod to permit rotational and axial movement of the polished rod in the bore of the clamp body.
