Description: |
| The screw adjustment in the face of the frame holds a curved toothed surface on the handle in engagement with rack teeth on the shank of the hook jaw. This arrangement allows for limited self-adjustment. The wrench is also shown with an alternate form of jaw faces to serve as a pipe cutter.
Improved by patent no. 481,110; patent no. 489,803 is another evolution. |
