This could indeed be a wheel from a wheat thresher because of the 29"
size and the center rib. I have tried to find a good shot of a steam tractor
with a wheat thresher. This site has a few years of photos and would be used
to see some examples of this design of wheel.

This has a steam tractor and a thresher, the wheels on the thresher
would seem to be about 29 or 30 inches. While a close examination shows these
wheels to be flat surfaced, I have seen the ridged wheels at Pontiac IL at the
"Old Thresher-man's Reunion" but I do not have a photo of those wheels.

As far as being a tensioner for a belt I have not seen ridged idler or
tensioner as it would cause wear to the belt. As you can--sort of---see on the
thresher the metal framework allows for pieces of metal to extend over or
under the belt with very small flat surfaced wheel(s)with a slight angle to
help keep the belt from slipping off. These small wheel usually look like
sections from a cone. As almost every one who has watched the steam tractors
run the long belts the engineer usually has a long wooden pole or paddle to
slide the belt back onto the center of the drive wheel (or more modernly -the
power take-off).
As far as being a piece of railroad equipment I was
wondering if any human powered equipment would have used something like this
for a fly wheel? That is all I have.
