Hayward-Tyler & Co, London 1910ca Rider patent hot air engine

In 1864 the American Alexander K. Rider filed a patent for a Rotary Steam Engine. He then turned his interest to the promising hot air engine and became a world leader in this field. After many trials and errors Alexander Rider built one of the best and most famous hot air engines and patented it in 1879 and 1880. The Rider air engine has been a very popular engine in America but was also employed in Europe and Australia.
It was found especially serviceable on railroads for filling water tanks; in public buildings, hotels, universities, asylums, city and country residences, and all descriptions of manufactories; for irrigation purposes; in short, wherever a small, neat, compact motor was required.
The engine was constructed with great care, and exhibiting superior workmanship, noiseless, simple, safe, economical, and efficient. It was built without the use of valves, springs, levers, or, in fact, any delicate parts whatever, the moving parts being reduced to the lowest possible number, namely, the pistons, shaft, and connections.
A detailed explanation of the working of the engine can be found here: http://hotairengines.org/closed-cycle-engine/rider-1875#data
The engine is symmetrical in appearance, has two separate and parallel cylinders, one on the cold side and the other on the hot side where the furnace is also to be found. This strict separation of the two sides is of much advantage as heat and cold do not mix together like in other engines. Rider’s patent was bought by several companies in America and Europe to manufacture hot air engines. One of them was the British firm of Hayward-Tyler & Co. It was formed in 1815 and is still operating as Hayward Tyler in the field of advanced pump systems, see https://haywardtyler.com/products
