Compression Hot-Air Pumping Engine
water pump on the model is made just like the original shown above.
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.*" - JEH
the castings are no longer available*, we are sometimes asked
for the plans, as some enterprising builders will go ahead and make the
cast parts from bar stock, and use the plans to build the entire
engine. We offer the plans here for $2.00 as an example of
Jerry's work. All the other plans available on this site
the same general flow and layout, except, of course, no castings
are required for them as they are made completely from bar stock..
plan set consist of 20 sheets of drawings (sheet one is a detailed
cutaway view) and 3 sheets of construction and assembly notes.
* Partial casting kits found. See this link: http://www.jerry-howell.com/forums/index.php?board=31.0
