Rider Compression Hot-Air Pumping
Engine
The prototype engines were made by the DeLamater Iron Works
of New York City during the late 1800's and early 1900's. They
were used for pumping water in country estate homes, on ranches,
railroads, greenhouses and other applications and were sold all
over the world. They came in 4", 5", 6", 8"
and 10" cylinder diameters. This engine was built from my
own "lost wax investment" castings. The flywheel is
3.330" diameter. Bore and stroke is .615"x .750".
The double acting "Rolling Valve" water pump has a .156"
bore and .750" stroke and will pump quite a stream of water.
The pumped water circulates around the cooler cylinder and some
also cools the top of the heater cylinder. The engine is fired
by a propane burner with a flame 1/2" diameter and less than
3/16" high. The engine runs cool, with the warmest part being
the furnace which is never too hot to touch. The regenerator passage
is fitted with very fine stainless steel screen wire folded accordian
style, but it is not known for certain how much effect it actually
has. In late 1999 I made this engine available as a serial numbered
"1 of 50" castings and material kits. These sold out
in just a few months and are NO LONGER
available.
The water pump on the model is made just like the
originals shown below.
