what does this tool do?

Other than it being a cutter of some type being manufactured in Chicago some time after June 1918 by the Paul W Kock co, what does this tool do?

Nice looking old tool. Does it have a ratchet action? I see it was patented, so does it have a pat. number on it? Very strange looking cutting tool, that looks like it would be used to cut inside pipe ridge or burr, and or pistion ring ridge. Just my WAG!

I sure don't know what it is but it is huge -- it makes that jeep look really tiny.

Yes it does ratchet, like most ratchets of the time it sure is no fine tooth though. It would be difficult to use as a ridge reamer, as there is no way to expand it under pressure.

I think it's missing a piece, it seems to be a hole cutter.
Koch was making stuff for the electrical trade, conduit stuff, panel tools etc, using the Jiffy' name .

If it is missing a piece that would make sense but it is not cutting a hole as it sits. I figure it can hang on the wall for what I paid for it.

I agree rusty! Looks like a match to me!

What ya have there is everything but the important parts of a Jiffy hole cutter.

Based on experience, the only thing they cut in a jiffy was a block of soft butter.
I wouldn't get too worked up to find the cutters.
