By an unknown maker, this steam engine was used to drive wooden paddles, via chain drive and line-shafting, in the sewage intake culvert. Slaked lime was mixed with the sewage to reduce the obnoxious smell and reduce the acidity of the waste from the nearby breweries. Claymills Victorian Pumping Station near Burton-upon-Trent

Liberty L-12 Aircraft Engine
The Liberty engine was designed at the request of the U.S. Government's Aircraft Production Board in May 1917. Designed in only five days it became one of the most produced and successful early American aircraft engines. The engine was specifically designed to be easy to mass produce and more than 20,000 were produced between 1917 and 1919. Most of the major and many smaller automobile manufacturers in the U.S. were given contracts to produce Liberty engines. This particular one was built by the Lewis Spring and Axle Company of Chelsea, Michigan.

I chemically stripped the paint from the camshaft cover but everytime I finished cleaning it oxidised and left white powdery residue. So I decided to have it shot blasted. Nice matt finish ready for primer.
The Sturtevant 5A engine, rated at 140 hp, powered the Sturtevant S-4 and some L.W.F. V-1 training airplanes used by the Signal Corps at North Island, Calif., and Mineola, N.Y., during 1916 and 1917. Neither of these airplanes proved suitable, partly because of the 5A engine's high power to weight ratio of 3.5 pounds per horsepower. The Army soon replaced those aircraft with the Standard J-1 and Curtiss JN-4 trainers.
