Abstract:
1. In a sucker rod tong comprising a body having an opening adapted to receive a sucker rod assembly, a rotatable jaw assembly operably engaged in the body at the opening and adapted to engage the sucker rod assembly, a powered mechanism adapted to rotate the jaw assembly, and a lower backup wrench operably positioned below the jaw assembly, wherein the sucker rod assembly includes a sucker rod having a threaded end and a coupling having a threaded inside wall that is threaded onto the threaded end of the sucker rod, and wherein the lower backup wrench is adapted to hold the sucker rod, the improvement comprising: an elongated shaft removably received in the jaw assembly, the shaft being operably engaged with the jaw assembly so that rotation of the jaw assembly causes the shaft to rotate, the shaft having opposing ends and an extractor on at least one end, wherein the extractor is sized and designed to bite into and engage with the threaded inside wall of the coupling while the shaft is rotated for unscrewing the coupling from the sucker rod, and a radial element that extends radially outwardly with respect to the longitudinal axis of the shaft, wherein the radial element is in a fixed relationship with respect to the shaft such that the radial element rotates about the longitudinal axis of the shaft while the shaft rotates about its longitudinal axis, and wherein the radial element is a driving flange that fits within and engages with the jaw assembly for receiving a rotational force from the jaw assembly and/or is a positioning flange that rests upon and/or engages with the jaw assembly for locating the extractor in a proper position with respect to the threaded inside wall of the coupling.
