Does the part extending up from the hub in your photos have jaws like a brace (as in, for auger bits)? If so, this was designed to bore large holes by being braced against something*, with the ratchet unthreading from the opposite side - that is, the tool getting longer as the ratchet worked. I am presently blanking on the term for the tool. Still in use in the early 20th century, before drill motors became powerful and affordable enough to replace them.
If that's what it is, and you're not interested, I might be if we can figure out cheap enough shipping and a reasonable price.
*Mechanics would set up a 4x4 or larger, supported properly, to brace the tool against. The 4x4 was known as an "old man," implying that old men are good for nothing but standing around. If I ever become an old man, instead of being a large child of 66, I might be insulted.
I think that is a scaffolding ratchet.
What does the end views look like, only see side views...
must have some type of hex or slot to drive something?
unless it is that hex nut that goes into something...

The internals of the knurled part reminds me of self adjusting brake calipers.
After looking again, I think it is some type of self adjusting ratchet, the alignment tip is coming to me now, it centers on one end, then would lift pretty much lift anything.
I think Bill had it! a drill driver. The back part was wedge with a clamp assembly, or lever or 2x4 (old man) to apply pressure when drilling by turning the knurled, the drill bit has a flat that fits into the driver..
Some of the old catalogs call them ratchet drills. They were typically used in conjunction with a large clamp the held it in place and provided the back pressure against the expanding end. I have often seen them with large square taper shank twist drill bits.
I have been told that they were used for drilling bolt holes in steel beams during building construction.
...would have to be tight between something to start the auto advance ratchet action.Exactly. You set up your braced piece of timber* next to the thing you want to drill a hole in, run it in until you run out of travel on the tool, and then, if needed, reverse it, put a piece of wood in as a shim, and repeat. The knurling is probably both to hold it in place while you're starting it and to quickly wind it back to "start" when you're done.
Great forum...Value ?Oh, this forum is priceless; no question.
