Description: |
| Adjustable alligator type pipe wrench including alternatives for replaceable gripping jaws faces, and a swinging grip which could be moved to either jaw face. A spring holds the jaws in "normal open" position.
Versions of this design marked "DU CHARME PAT" are known with and without the center swinging grip. Based on the company history, it appears these were produced at Cambridge, OH.
The swinging gripper appears in altered form in a wrench produced by the Efficient Vise & Wrench Co. of Cleveland. W. S. DuCharme was President of that company in the early 1920s. |
