Description: |
| The basic wrench is a wedge-adjust of the type patented by John R. Long in patent nos. 890,146 and 955,974.
The specific details covered in this patent focus on pipe wrenches, and include the stops for the movable jaw, the fixed jaw and insert, and the friction spring inside the yoke. The friction spring also appears in Fitzgerald's parallel nut wrench patent no. 1,004,562.
This patent invites close comparison to the pipe wrench version of the FITZ-ALL wrench produced by the STANDARD WRENCH & TOOL Co. of Providence, R.I., which was introduced in early 1912. Its markings cite the two J.R. Long patents noted above. The company sold in bankruptcy in 1913. |
