Can anyone help identify this tool?

[AlD]

Help! I picked this thing up recently, and although I've seen them before, there aren't enough clues on it to help me identify it. It has a ratchet action, a 3/8" female drive on the back of the ratchet (apparently for a breaker bar to go into), and is made by Keystone Manufacturing in Buffalo with a patent date of March 12, 1912, but a Google search didn't yield anything. Anyone seen one of these before?

Thanks in advance!
