HEINRICI

This small hot air engine was made in Germany about 1890.  It operates on the Stirling Cycle in which an external heat source, such as the gas burner in the base, causes hot and cold air to bounce between two concentric pistons to produce power.  It is inefficient but very easy to operate so these hot air engines became popular for a short time.  It could have powered an industrial sewing machine or some other small machine.  It was so much easier to use than a small steam engine which require a boiler. 

Crossley

CROSSLEY MODEL J

This engine was built by Crossley Bros. of Manchester, England and produces 3 hp.  It is circa 1910 but the J evolved from the earlier Crossley slide valve engines.  This engine has hot tube ignition and hit and miss pendulum governor.  Note the gas bag regulator behind the engine which is typically English.  It powered three small looms in Stirling, Scotland. 

Domestic

DOMESTIC

This 4 1/2 hp engine was built in Shippensburg, PA in 1905.  It is the earliest known to exist and one of 13 that were built.  It shows similarities to later Domestics but has many unique features.  Note the huge tappet roller on the rocker arm and the solid brass connecting rod.  It operated a woodworking shop in Ft. Loudoun, PA and was removed in the early 1950s. 

Angola

ANGOLA

This beautiful 4 hp engine was built by the Angola Engine and Foundry Co. of Angola, Indiana about 1904.  This was a small concern that ended in 1911.  It features a nicely rounded cylinder head and governor spaced back on the side shaft.  No information is available to its prior use.  Likely a small shop.
