What is this thing.

It seems to be made of copper because is has a green patina. Here is a liberty head nickel for comparison. Any ideas?

Looks like the turn part from a crescent wrench.

Test it with a magnet to see if its steel.

I agree with BigCy
Also antique monkey wrench

I's called a "worm gear". Could be from an old adjustable but if it is brass, probably from a small gear box. Tony

I think Tony is on to something because I see no knurling on the threads for a thumb/finger grip.

It is not magnetic. I think it might be brass too. It is as green as the 1880 IH that I found within 15 ft. Thanks for the help.

I googled old "brass worm gear" and this is what I got. Yours appears to be much older and the center hole is offcenter. http://images.google.com/imgres?img...que+%22brass+worm+gear%22&um=1&hl=en&lr=&sa=N

I think you can write this one 'solved' as a worm gear.

if its a brass worm gear it could be from a water valve also.
