Description: |
| A spring-loaded lever between the movable jaw and shank is the adjusting means. The lever has teeth that mesh with rack teeth on the movable jaw. The overall design of the wrench is similar to the Stillson style pipe wrench evolved from Daniel Stillson's Oct. 12, 1869 patent (no. 95,744). |
