Found this yesterday at a flea market. I don't know its application, and would welcome input about that and the company that made it.
Here is a link (http://www.datamp.org/patents/displayPatent.php?pn=1896437&id=42314) to the U S Patent. Looks like you got a pipe wrench.
Shaped like an involute wrench. Is the longer jaw broken?
No, that is the standard configuration for this wrench (and why I bought it).
Steel City made electrical fittings, particularly conduit.....
So, likely targeted at the electrical trade for conduit assembly (The threaded pipe screw in type)
Thanks!!
Is it about 8 inches long?
Nope. 11 1//2 inches long.
This one is on ebay but as Papaw suggested it has a longer outer jaw but is the same overall length.

I was sure I had seen it before.
