Cole drill or Blacksmith drill

Cole drill was a brand name but there were several different companies producing this style of ratcheting drill the one above was a "little giant"brand drill i no longer have this one i sold it on ebay several years ago.
Ebay is probably the only place your likely to find one they usually go for $100.00 or more. 

What's so special about a drill like this?well this drill's design puts up to 1000 pounds of pressure on the tip of the drill bit allowing you to drill through just about any metal quickly.

Have you ever tried drilling a 3/4" hole through 3/8" plate without power tools? Or with an electric hand drill? The Cole drill can do it in about 45-60 seconds! For items that can't be put on a drill table because of size or location, the Cole drill is a good tool to have.

I had 2 of these after selling the one above (Made of aluminum ) I kept the cast iron one pictured below it is about 50% larger and of course more of a heavy duty construction.
It has a no.20 on the side and on the top of the large bolt it says portable equipment co. Merrill Iowa U.S.A.
I've also used it a couple of times as a "C" clamp as you can imagine it really holds tight.

                          Silver and Deming drill bits are used but many people just add a drill chuck.
 The shaft turns inside the the threaded bolt. turning the bolt forces the shaft downward putting force on the drill bit.

The ratchet action only works in one direction

This one is missing the V block from the bottom which is common for these 
Here it is shown with a 5/8 drill chuck attached
