Description: |
| A cam-action end at the pivot end of the swinging handle pulls the rack on the inside face of the movable jaw against a corresponding rack on the face of the main shank.
A known example is marked "QUICK GRIP WRENCH CO. DULUTH MINN. // PAT. JUNE 8, 1915."
Most HEIMBACH patent wrenches incorporate some features covered in his May 10, 1921 patent (no, 1,377,772), including a curved end fixed jaw rather than the "hammer poll" style jaw shown in this patent. |
