There's nothing particularly special about this offset/parrot head pipe wrench, found at my Thursday flea market, I just couldn't find anywhere else to post it, with no other example or reference to LAWSON (Gottfrid C., the patent holder), or to USHCO MFG CO., BUFFALO, N.Y. here on GJ as far as I can tell, other than its inclusion on four.cycle's "List of U.S. Manufacturers" thread.
The original patent (1,362,014) was granted December 14, 1920.
According to DATAMP, there were three other manufacturers of this pipe wrench: Lawson Mfg Co. (ostensibly a company the patent owner started), U.S. Hame Co., and Fairmount Tool & Forge, all in Cleveland, Ohio, the home of the patent owner. Link to DATAMP page, and link from there to USPTO site, here.
DATAMP makes no note of this, but I have a strong suspicion that "USHCO" is an acronym for U.S. Hame Company, and that it moved at some point in time from Cleveland to Buffalo. When is unknown.
I have not done any biographical research on Mr. Lawson.
This 8-inch long example has been de-rusted, but is unfortunately marred with box rot stains and some pitting. Most of the markings are legible, but there is a marking preceding the forged-in "LAWSON" marking that may be "PAT'D". I'm not sure. Google searches or other collectors' examples may confirm or clarify that.
