Description: |
| The main patented feature is the rocking motion of the handle adding pressure to the face of the jaw attached to the handle. The feature is shown as adapted to a screw-adjust or quick-adjust movable jaw.
A known example marked with this patent date has a screw-adjusting jaw, and has been modified to work as a pipe wrench. The Clearwater, CA location may refer to a 1922 start-up producing Bessolo's oil-well drill stem & casing tongs. (See patent nos. 1,447,920 ) |
