Description:
The manufacturing process described would produce the head and shank of a monkey wrench by welding two pieces of iron together rather than forging the head and shank from a single piece.

Wrenches marked with this patent date are part of an evolving design sequence extending over most of the 1850s, and produced by Taft and a sequence of associates at Worcester.
