Description: |
| The specifications call this an improvement on the "Magee Wrench" (Pat. No. 98,393, Dec. 28, 1969). The sliding jaw has a quick-adjust gib, and the screw adjust provides the final adjustment for the intervals between the positions provided by the rack notches. The patent includes the shape of the rack notches and the shape of the tension spring. |
