Description: |
| The specifications describe jaw surfaces grooved to grip pipe. The primary feature of interest is the side lever which pulls out to provide extra leverage to the adjustment. A clip on the side of the handle stores the side lever when it is not needed.
The wrench as produced a decade later includes refinements covered by patent nos. 3,023,653 and 3,024,683.
Pat. no. 2,750,829 (used by UTICA) and 2,729,999 cite this patent in the references. |
