Description: |
The worm adjustable jaw portion is substantially the same as E. J. Worcester's June 9, 1857 patent (no. 17,531), and is not claimed in this patent. What is claimed is additional gear wheels to move the point of contact for the adjustment mechanism closer to the normal hand grip. The handle also has a square socket in the end. |
