Description:
The design includes a thicker reinforcing portion around the perimeter of the handle, and on both faces of the jaws.

The design was used for drop forged alligator wrenches produced by several successive manufacturers and widely distributed. Some are marked with hardware wholesaler's names or as "advertising give-aways."

The same outline appears in a parallel series of stamped steel alligator wrenches. Some of the drop forged wrenches are marked with the patent date.

Vaughan & Bushnell's parallel design patent (no. D29,109) has the reinforcement only at the jaws, and a different arrangement of the wrench holes in the handle.

Term of patent 14 years.
