A Rider hot air engine from the Adirondacks

Rider hot air engines run on expanding air in the heated cylinder and cooling air in the cool or 'compression' cylinder. Air is shunted back and forth through regenerator (heat exchanger) plates in the passage between the two cylinders. This scarce 5-inch (about 13 cm) bore engine was built around 1902-03 by the Rider-Ericsson Engine Co. and was found in upper New York state. It was the deep well option with a long rod to the pump down in the well.

Thank you - I especially like the detail of the leather seals you show here, flexing with pressure and piston motion. Between folks like you and reading Lyle Cummins, I think I'm starting to get a solid understanding.

I have an old magazine from 1907. There's an ad for one of these in it.
