Description:

Pipe wrench design with the shank of the movable jaw contained within the handle. The inventor's first name is spelled as it appears in the specifications.

A 1938 Vonnegut Hardware catalog entry and British patent no. 189,395 are cited as references.

An early 1950s CRAFTSMAN pipe wrench is very close to this design; the hand grip portion of the handle is different.
