Luther bench vice

[OlioReader]

I found this fun little bench vice at an estate sale.  It is made by the Luther Grinder Manufacturing Co. (Milwaukee).  The jaws are 2 1/2", opens up to 3 1/4 inches and weighs 11 lbs. It is in great shape; I just used a wire brush and put 3-in-1 oil on the threads to bring it back to good working order.  I still have some rust to take care of, but it seems superficial.  I've never seen a bench vice like this and I think it will work great for my small forging projects.  I don't have a dedicated space where I can permanently set up my forge/anvil/vice so  I won't need to carry my huge 6" jaw machinist vice to the work area.  

I didn't find much about the Luther company.  My internet sleuthing only brought me to a brief post on the vintage machinery site: " This company is known to have been active in the 1910s and 1920s, and probably for longer. They made hand-powered bench grinders."  Not much else out there about them that I can find.  Does anyone else have any ideas about the company or when this may have been made?

I have an identical vice and have scoured the internet for information to no avail. I tried the US Patent office but kept hitting roadblocks in my searches. It looks like the Patent office might be the best bet so I guess I'll just have to figure it out.

Garry,

Google patents is also very useful for patent searching.

Try patents. google.com

another database is http://www.freepatentsonline.com/search.html

For European patents try,

I have not used this site but it's worth a try.
