What are these used for?

[HeelSpur]

Got these from an auction last month.
The first one has 2 cutter wheels and I guess 2 guide wheels. The cutter wheels line up with the wide groove on the guide wheel and there are washers that line up with the narrow groove on the guide wheel.

And this one had thoughts of being a piston groove cleaner.

The first one is almost definitely a tube cutter design for a larger diameter pipe. 2 cutter wheels and 2 follower wheels to hold the pipe and align the cutters.

The second one looks like a homemade version for cutting/perforating a softer material. Maybe cutting lines of holes in PVC pipe to make irrigation lines. Could be used to cut bamboo if they were sharp.

first one definitely a really interesting version of a tubing/pipe cutter.
second one... I'm going to go with some sort of device used for perforating cylindrical/round objects., although I cannot imagine what the application might be.

any maker's mark, patent numbers, or patent dates on either of them?

My vote is the second one is for cutting soil pipe. Soil pipe is tar-impregnated paper that was used for sewer and drain lines in the old days.

If that were the case, is it possible the first pic might be for cast iron pipe?

first is a pipe cutter.
second ; my guess is a clay tile cutter

No markings whatsoever. The first one does have a brass or bronze body. I was thinking Orangeburg pipe but had no clue. 5 bux for the pair.

Orangeburg! GAH!
The plumber who charged $8000.00 to replace my outgoing sewer line and incoming water line said that about half of the houses here in Tacoma were plumbed with that garbage, ensuring job security for both he and his son as long as they lived.
Whoever it was who came up with the idea of that stuff should have been flayed alive and slowly roasted over a fire!

Heelspur, you finally found the tools from GULAG used to get confessions from the innocent prisoners!!!

My initial impression on the first one was an exhaust cutter.
