I usually don't reply to answers for items that are also on Neatorama, but since
someone already got it I'll go ahead and say that this is correct. Or at least
mostly correct, the Dictionary of American Hand Tools has a slightly different
definition for this tool.
I looked it up. It is called a traveller or wheelwright's traveller.
Now my confusion is greatly reduced. I still have the nitpicking issue
that wheels have to be round. The traveller, run around the
circumference doesn't check that the wheel isn't slightly elliptical.
If the wheelwright spins the wheel to check that it is round, then a
yardstick should do a good job of checking the size. But... I've
learned not to argue with or question a professional doing his job.

You don't need a mathematical equation if you simply
put the correct markings on the measuring stick.
Seems like measuring with a non-elastic string or
wire would be more accurate than running a wheel
around another wheel.
Wheels had hubs. Besides, they didn't stay round.
If a customer had a damaged wheel, I think giving it a spin under the
traveler would be an easy to see what size it had been.
Measuring flat iron for a tire was easy: roll the wheel along it, then
cut 2 or 3" longer. Bending it into a circle would shorten it. That's
where the traveler came in: measure the wheel and measure the C-shaped
tire before welding.
Still a problem with cross-posting replies...

It certainly looks like a wheel used to measure length, but I was/am
confused. I don't see a turns-counter. Without a rotation counter, I'd
expect the use to be limited to distances of only a few circumferences,
and I find it hard to imagine the specific use.

Btw, I'm glad that thing are back to normal with most all of the replies in one
thread, it's much easy for me that way.
Which is actually how proper netquette expects us to behave.
However, I have no desire to follow the other two newsgroups (just
rec.crafts.metalworking), and I'm sure that others feel the same way, so
I consider this to be an exception to the restriction of followups to a
single newsgroup. (And my newsreader reminds me every time I post in
these threads. :-)
There is even a "Followup-To: " header to force the discussion
to a specific newsgroup when it has been started cross-posted to gather
interest. (And a bit of a "puzzlement" to those who don't notice it,
and don't see what they posted in the newsgroup in which they posted the
reply -- sometimes the try again and again. :-)
Good guess! Plug cutter is correct. It was a good week, I'm always happy when
mystery items all get identified. The answers for this set can be seen here:
2839: According to H. G. Holmstrom in _Modern__Blacksmithing_ (1904),
the traveler was not required to measure the flat iron. It was used
after the tire was bent into a circle, which was probably irregular.
