Israel Kinney patent adjustable wrench. Patent # 250,367. Made by E.G. Felthousen of Buffalo NY.
I bought it thinking it was a NY wrench, turns out it's not. At least wasn't patented by a NY resident. Once I can determine a value I'll most likely move it along to somebody that has more interest in it than I do now. This is a different variant than Stan used on the DATAMP picture. I'm thinking it's a very early example since it looks more like the patent picture than the one on DATAMP. It's also marked with "NO. 1", meaning more than 1 size was made perhaps?
Could be one of the most useless type wrenches I've ever seen.
