ABSTRACT:
A power tubing tong is modified by removing the gripping jaws and in attaching a sucker rod break-out adapter where the gripping jaws would normally be placed. The adapter includes a vise anvil and a vise block so that a sucker rod may be securely, rigidly fastened by a vise bolt moving the vise block so that the sucker rod is between the vise block and the vise anvil. This provides a tong capable of breaking a sucker rod joint when the pump attached to the bottom of the sucker rod is stuck. In use, the adapted tong would be used to break a sucker rod at some point between the surface of the earth and the pump when it was desired to pull the pump for routine maintenance and repair.
