| 124 | Compact high-torque apparatus and method for rotating pipe | US95526 | 1987-09-10 | US4843924A | 1989-07-04 | Thomas D. Hauk |
| Apparatus for rotating a tubular well element about its longitudinal axis. There are first and second elongate casing sections pivotally connected to each other at a pivot. First and second driven sprockets are mounted, respectively, on the casing sections at locations remote from the pivot. A drive sprocket, mounted on the first casing section, is driven by a motor-gear assembly. A continuous chain is mounted around the drive sprocket, and around the first and second driven sprockets, having an inverse internal portion adapted to receive and directly contact the tubular well element to be rotated. Cylinders are connected between the casing sections to pivot them toward and away from each other and thus alternately clamp the inverse internal portion around the wall element, and release such element from the inverse internal portion. One end of each cylinder is pivotally connected to the first casing section at a point between the pivot and the first driven sprocket. The other end of each cylinder is pivotally connected to the second casing section at a point between the pivot and the second driven sprocket. | ||||||

| 126 | Powered pipe wrench | US922427 | 1986-10-23 | US4729269A | 1988-03-08 | Richard H. Killian |
| A pipe wrenching tool adapted to be powered by a hand held power drive mechanism is formed with a support for a drive wheel and an idler wheel with the idler wheel being movable with respect to the drive wheel to adjust the tool for differing sizes of pipe. The tool is adapted to interface transversely to the axis of the pipe to be wrenched with the drive wheel engaging the pipe without requiring a part of the tool to circumscribe the pipe. The rotational axis of the idler wheel and rotational axis of the drive wheel are off-set with respect to each other to cause the pipe being wrenched to be forced into the tool. The tool is adapted at both sides to have the drive source attached at the side of the tool away from the pipe so that the tool may be used to engage and wrench pipe in confined spaces. Only the wheels of the tool are rotated; the tool need not rotate with respect to the pipe. | ||||||
