| 20090308208 | Anti-Slip Pipe Threading Wrench - This invention relates to a standard pipe threading wrench and prevents an inherent malfunction when ratcheting. This type of wrench has been on the market for many decades unchanged. To use the wrench the die is inserted into the wrench head. The die, with attached wrench, is slipped over the end of an unthreaded pipe. The wrench handle is used to rotate the die and cut tapered threads into the pipe end. The wrench head rotates the die in one direction and ratchets in the opposite direction, allowing the user to reassert leverage on the handle from the same position. The ratcheting action is accomplished via a tapered and spring loaded pawl in the wrench head. The ratcheting teeth are in the die. The pawl also performs a second function holding the die in the wrench head as it is extended radially inward between two retaining rings in the die. If the user moves the handle out of the plane perpendicular to the pipe being threaded, the pawl will ride against one of the retaining rings and slip past the die ratchet teeth without engaging. The resulting rotational slippage can, and has caused, serious injury if the user is in a precarious position. This invention removes the retaining function from the ratcheting pawl preventing slippage and enhancing safety. | 12-17-2009 |
