Description: |
| An improvement on the wedge-adjust wrench based on John R. Long patent nos. 890,146 and 955,974.
A motion stop on the back limits movement of the binding yoke, and a friction spring improves coordination of the yoke and movable jaw. The friction spring also appears in Fitzgerald's parallel pipe wrench patent no. 1,004,561. |
