Description: |
| The patent claims the solid body with screw adjustment for the chain, gripping jaw faces at an obtuse angle to each other, and other general features of the design.
The Canadian Patents Database does not include the original cover sheet which contained details of the application date and patentee's address. Many features of the patent correspond to Carnelli's U.S. patent 1,828,173 granted Oct. 20, 1931. That patent is cited on the E-ZEE TOOL MFG. CO. CERTUL chain pipe wrench. |
