Charles Yale Knight (1868 – 1940) was an entrepreneur and inventor of the sleeve valve technology. His Knight engines would be used in the early cars, British tanks, and British aircraft. Customers included Henry Ford's competitor, John Willys and his company, Willys–Overland Motors, second largest car manufacturer after Ford Motor, as well as by Daimler, Mercedes, Peugeot and others.[1][2] He was a millionaire by the time he was 44 years of age, in 1912.

History

Knight was originally an American printer and newspaper publisher, publishing a Midwest farm journal called Dairy Produce. To cover dairy activities during 1901–02, he bought an early Knox automobile, a three-wheeler with an air-cooled, single-cylinder engine whose noisy valves annoyed him.
He believed that he could design a better engine and proceeded to do so. Knight was familiar with the slide valves used on early Otto engines, having repaired the similar valve mechanism in his father's sawmill. The slide valve had, however, been replaced in gasoline engines by the poppet valve, whose characteristics were better suited to four-stroke engines.
At first Knight tried making the entire engine cylinder reciprocate to open and close the exhaust and inlet ports. Though he patented this arrangement, he soon abandoned it in favour of a double sliding sleeve principle. Backed by Chicago entrepreneur L.B. Kilbourne, an experimental engine was built in Oak Park, Illinois in 1903.[3] Research and development continued until 1905, when a prototype passed stringent tests in Elyria, Ohio.
Having developed a practicable engine (at a cost of around $150,000), Knight and Kilbourne showed a complete "Silent Knight" touring car at the 1906 Chicago Auto Show.[4] Fitted with a 4-cylinder, 40 hp (30 kW) engine, the car was priced at $3,500. His radically different motor was mocked by engineers and designers, who were mainly concerned by making their cars run, rather than optimizing for efficiency, comfort, silence and high power.[5] The automobile industry in the United States was still behind the one in Great Britain at the time.[5]
Knight thought otherwise, and saw his engines as superior theoretically, but also practically, which had others named him "Just a freak".[5] Around 1907, he signed a deal with the Chairman of Daimler Motor Company, the oldest manufacturer in Great Britain, for the right to use his Silent-Knight engine technology in their cars.[6][7][5] He also lobbied successfully Congress against Senator Mark Hanna.[8]
A deal was done with Percy Martin, managing director of the Birmingham Small Arms Company. In 1908, Charles obtained a deal with Minerva motors, where they would use his technology for their entire fleet.[9] When they were presenting the cars in New York, with the latest Yale engines, they sold models to the King of Norway, Sweden, and Belgium, and another two to Henry Ford.[10] The company would later be sold to German car and arms manufacturer, Rheinmetall. In 1910, Panhard automobile, one of the first car manufacturers, started using the sleeve valve system.[11]
In 1911, the Stearns-Knight company became the first American car manufacturer using the technology, and would later be sold to John Willys, US Ambassador and owner of the Duesenberg company, as well as employer of Walter Chrysler.[12] Willys Company would launch and sell the Willys-Knight automobile and would end up becoming the second largest car manufacturer in the United States, following the Ford motor company of Henry Ford.[13][14] The company would later merge with Kaiser Jeep, a World War II military jeep manufacturer. Later on, after racing the Vanderbilt Cup, the Atlas company would also change their engines for the Knight technology, and become the Atlas-Knight company.
Also, following the end of World War I, Gabriel Voisin, an airplane manufacturer and owner of Aeroplanes Voisin, would switch his activity to car manufacturing and found the Avions Voisin company using Charles Yale Knight engines as well. His sleeve valve motor was shown at Fort Wayne in 1917, by invitation of the Fort Wayne Automobile Trade Association in Indiana.[15]

As of 1913, 26 car manufacturers in total were using the Knight engine technology, 9 French, 4 American, 4 German, 3 British, 2 Austrian, 2 Belgium, 1 Swiss, and 1 Canadian automobile company.[16]
Walter Owen Bentley of Bentley Motors : In those Edwardian days it was the Daimler-Knight engine which was regarded as the nearest to perfection...its big sleeve valves provided the superlative silence so highly esteemed by the Edwardian chauffeur and his master and mistress and the ... Daimler performed quite as well as the Silver Ghost Rolls-Royce.[17]

Military sleeve valve engines

Daimler-Knight's sleeve valve engines were used in the first British tanks in World War I such as the Mark I tank, Mark II tank, Mark IV tank and others. Later, the sleeve valve technology invented by Charles Yale Knight will be modified and used by the British to build aircraft engines. One of these companies was the Bristol Aeroplane Company, one of the first British aviation manufacturer.
They produced sleeve valve equipped airplanes such as the : Short Stirling, Hawker Tempest, Bristol Brabazon, Handley Page Halifax, Hawker Sea Fury, Bristol Beaufighter, Vickers Warwick, Airspeed Ambassador, Bristol Beaufort, Napier-Heston Racer, Westland Lysander, Hawker Typhoon, Blackburn Skua.
