Zoller Supercharger
The Zoller supercharger was a vane-type supercharger created by (1882-1934) who had patents regarding supercharging engines before WW1. The Zoller supercharger was popular in the 1920s and 1930s. Company History In the UK the distributor for Zoller superchargers was Forced Induction Ltd of London c1931, then M.A. McEvoy (London) Ltd of Leaper Street Works, Derby. A McEvoy advert in 1933 claimed they designed, and made the Zoller superchargers. Supporting that they were manufactured in the UK was an article from 1939 which stated that they were manufactured in the UK from 1931 to 1936. This also stated that they were made under licence by Petters Limited of Yeovil for application to their 2-stroke engine, though by 1945 the Petter superscavenge (SS) engine had Roots-type blowers (Holmes-Connersville blowers on the six cylinder). Although Arnold Zoller died in 1934, McEvoy displayed the Zoller supercharger (manufactured at their Derby works) at the 1935 Berlin show, and it appea ...

Supercharger
In an internal combustion engine, a supercharger compresses the intake gas, forcing more air into the engine in order to produce more power for a given displacement. The current categorisation is that a supercharger is a form of forced induction that is mechanically powered (usually by a belt from the engine's crankshaft), as opposed to a turbocharger, which is powered by the kinetic energy of the exhaust gasses. However, up until the mid-20th century, a turbocharger was called a "turbosupercharger" and was considered a type of supercharger. The first supercharged engine was built in 1878, with usage in aircraft engines beginning in the 1910s and usage in car engines beginning in the 1920s. In piston engines used by aircraft, supercharging was often used to compensate for the lower air density at high altitudes. Supercharging is less commonly used in the 21st century, as manufacturers have shifted to turbochargers to reduce fuel consumption and/or increase power outputs. Des ...

Petters Limited
Petters Limited (known as JB Petter & Sons of Yeovil until 1910), were a maker of stationary petrol and diesel engines from 1896 onwards.Petter, Percival. ''The Story of Petters Limited'' (Westbury: David Edgington, 1989) In 1915 Petter founded Westland Aircraft Works (renamed "Westland Aircraft" in 1935). In 1986 Petters Limited merged with one-time rival R A Lister and Company to form Lister Petter. History Car James Bazeley Petter, an agricultural engineer and iron founder, had premises in the Borough, Yeovil.Lukins, A. H. ''The Book of Westland Aircraft'' (Leicester: Harborough, 1944), p. 5 It was there that Ernest and Percival, his twin sons, designed and built a self-propelled oil engine in 1892.http://www.southsomersetmuseums.gov.uk/monographs/monograph01.htm Three years later they designed the first internal combustion engined motor car to be made in the United Kingdom. The car, using a converted four-wheel horse-drawn phaeton and a 3 hp (2 kW) twin-cylinder h ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Yeovil
Yeovil ( ) is a town and civil parishes in England, civil parish in the district of South Somerset, England. The population of Yeovil at the last census (2011) was 45,784. More recent estimates show a population of 48,564. It is close to Somerset's southern border with Dorset, from London, south of Bristol, from Sherborne and from Taunton. The aircraft and defence industries which developed in the 20th century made it a target for bombing in the Second World War; they are still major employers. Yeovil Country Park, which includes Ninesprings, is one of several open spaces with educational, cultural and sporting facilities. Religious sites include the 14th-century Church of St John the Baptist, Yeovil, Church of St John the Baptist. The town is on the A30 road, A30 and A37 road, A37 roads and has two railway stations. History Archaeological surveys have yielded Palaeolithic burial and settlement sites mainly to the south of the modern town, particularly in Hendford, where a ...

DKW SS 350
The DKW SS 350 was a racing motorcycle. 1935 saw the introduction of Dampf-Kraft-Wagen's first "over the counter" racer with the announcement of the SS250 at that year's Berlin Show. The model was quickly followed by a 350 cc version, the SS350, which drew on the works team's experience. Features In the (very limited) production application the water-cooled engine retained the vertical cylinder but placed the crank driven supercharger piston and its cylinder under the crankcases. The radiator was mounted between the twin downtubes of the plunger suspended double cradle frame and drive was taken to the four speed gearbox via a chain primary drive and dry multidisc clutch. Girder forks equipped the front end and were fitted with a full width hub as was the rear wheel. Engine In its 1939, 350 cc form, the SS engine had a bore of 39.5 mm for each of the two pistons and a stroke of 68.5 mm, which with the aid of the supercharger resulted in a claimed power outp ...

Marendaz
Marendaz Special cars were made in Brixton Road, London SW9, England from 1926 to 1932 and in Maidenhead, Berkshire, England from 1932 to 1936. DMK (Donald Marcus Kelway) Marendaz served as an apprentice at Siddeley-Deasy before the first World War. He left to join the Royal Flying Corps in 1916, training as a pilot and serving in France until invalided out in 1918 with the rank of lieutenant. After 1918, he joined Alvis, but was sacked, and shortly afterwards started Marseel with a Mr Seelhaft; the company manufactured gearboxes for the Emscote car. Emscote did not take all the gearboxes they made, so the surplus were used with Coventry-Simplex engines to make complete cars. The company changed its name to Marseal in 1923, when Seelhart left. Between 1920 and 1925, when Marseal failed, as many as 1200 cars might have been made in the Coventry factory. After a brief period in the City of London, in 1926 the 'Captain' started DMK Marendaz Ltd in the premises of the London ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
AJS V4
The AJS V4 (1935 – 1939) started out as a prototype air-cooled V4 road bike, but became a water-cooled and supercharged racing bike. The 1935 Olympia Show bike In 1935, at the Olympia Show, the Bert Collier designed air-cooled 495cc sohc AJS 50° V4 was first displayed. It was a fully equipped road going version, which did not make it into production. This first version used a common crankcase with four individual cast iron cylinders and separate alloy heads, with exposed hairpin valve springs, and a 180° crankshaft with forked conrods. There was a central carburettor for each pair of cylinders, and fore and aft exhausts. The single overhead camshafts were chain driven. It had chain primary drive in an oil bath primary chain-case, and a wet clutch. It was stated by AJS at the time that there would be the option of replacing the forward mounted chain driven dynamo with a supercharger. The AJS used a rigid frame with girder forks.Title: ''Classic Racer'' magazine, Issue: 121, A ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
English Racing Automobiles
English Racing Automobiles (ERA) was a British racing car manufacturer active from 1933 to 1954. Prewar history ERA was founded by Humphrey Cook, Raymond Mays, and Peter Berthon in November 1933 and established in Bourne, Lincolnshire, next to Eastgate House, the family home of Raymond Mays between Eastgate road and Spalding road. Their ambition was to manufacture and campaign a team of single seater racing cars capable of upholding British prestige in Continental European racing. With the cost of full Grand Prix racing prohibitive, they instead aimed ERA's efforts at the smaller voiturette—1500cc supercharged—class of motor racing, the Formula 2 equivalent of the day. Humphrey Cook financed the operation—using the wealth from the family drapery business, Cook, Son & Co., of St Paul's Churchyard, London. Berthon was responsible for the overall design of the cars, while Mays became its principal driver—having already successfully raced several other makes including Vaux ...
