Another Mystery Wrench. What is it?

[Hotfoot]

Again, I was followed home from the estate sale by a Mystery Wrench. This one is a ratchet handle marked "Patented 1914" on one side. Chicago Mfg.and Distributing Company" on the other. It came with five sockets, three square, two hex. The sockets are cast, but as thin-walled as sheet steel, and what was unusual to me are the three square ones. I figured iy for pipe fittings, (like plugs), but???:confused:

Looks like a ratchet and sockets for square and hex head plugs.:D

My grandfather had almost an identical set from the farm. Basicly just a ratchet set for hex and square head hardware. The hole in each socket allows a threaded rod to come through. Hmmm I think Sears was selling something similiar last time I was there........called an "o" drive or something of that nature......how original.

I have some wrenches like that. I got them from a gas company I worked for they were throwing them away. There not as old as yours they used them for compression clamps (dayton style).
