Description: |
| The adjustable jaw is held open by a spring, and the opening size adjusted by a "stepped" wedge. Both the fixed and adjustable ends are "alligator wrenches." The patent claims the structure and function of the adjustable jaw.
A known example is marked with the patentee name and patent date.
Compare the wedge adjustment in this wrench to the T.F. Vandegrift patent 444,171.
