Description: |
| A quick-adjust wrench with a spring-tensioned jaw having teeth engaging rack teeth on the main shank. The patent shows alternate forms for pipe and nut wrenches.
Produced and marketed as the VANDY pipe wrench; very rare compared to the wedge-adjust adjustable end wrench patented by Vandegrift one week earlier (pat. no. 444,171). |
