Powerwheel
Cyril Pullin (18 August 1892 – 23 April 1973) was a British inventor, engineer and motorcycle race driver. His inventions contributed to the rotary engine and the helicopter. His son was the pilot for the first successful British helicopter flight in 1938. Cyril Pullin died in 1973 aged 80. Early life Cyril George Pullin was born 1892 in Wandsworth, London. He became a well known motorcycle racer and in 1914 won the Isle of Man TT race. Racing career In 1914 Cyril Pullin won the Isle of Man TT with a record average of 49.49 mph on a Rudge Multi which had a variable belt drive gearbox giving an effective option of over 20 speeds which made a huge difference on the hills. The race, which ran for over four hours was led by Oliver Godfrey (riding an Indian) and Howard R Davies (on a Sunbeam) who dead heated for second place when Pullin overtook them both to win by only 6.4 seconds. Pullin's success on the day was sadly marred when fellow competitor in the Junior ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Ascot-Pullin Motorcycles
Ascot-Pullin Motorcycles was a British motorcycle manufacturer founded by Cyril Pullin as the Ascot Motor & Manufacturing Co Ltd. at Letchworth, Hertfordshire in 1928. An inventor and winner of the 1914 Isle of Man TT, Pullin had been developing ideas for motorcycle designs since 1920 with Stanley Groom, and had patented a two-stroke engine motorcycle with pressed sheet metal frame and forks. After leaving Douglas the first time, Pullin worked with Groom again to refine his ideas and develop and patent the Ascot-Pullin motorcycle. Fewer than 500 were built and sales were poor, resulting in the company's liquidation in 1930. Ascot-Pullin 500 Pullin was an innovator and the Ascot-Pullin 500 OHV single had the engine horizontally mounted and enclosed with a pressed-steel frame. As well as the first use of hydraulic brakes on a motorcycle, Pullin also designed a telescopic centre stand and an adjustable windshield with a windscreen wiper and rear-view mirror, as well as a ful ...

Rotary Engine
The rotary engine is an early type of internal combustion engine, usually designed with an odd number of cylinders per row in a radial configuration. The engine's crankshaft remained stationary in operation, while the entire crankcase and its attached cylinders rotated around it as a unit. Its main application was in aviation, although it also saw use in a few early motorcycles and automobiles. This type of engine was widely used as an alternative to conventional inline engines (straight or V) during World War I and the years immediately preceding that conflict. It has been described as "a very efficient solution to the problems of power output, weight, and reliability". By the early 1920s, the inherent limitations of this type of engine had rendered it obsolete. Description Distinction between "rotary" and "radial" engines A rotary engine is essentially a standard Otto cycle engine, with cylinders arranged radially around a central crankshaft just like a conventional ra ...

Sunbeam Cycles
Sunbeam Cycles made by John Marston Limited of Wolverhampton was a British brand of bicycles and, from 1912 to 1956 motorcycles. On John Marston's death after the First World War it was bought by Nobel Industries, Nobel became ICI. Associated Motor Cycles bought it in 1937; then, BSA bought Sunbeam in 1943. Sunbeam Cycles is most famous for its S7 balloon-tyred shaft-drive motorcycle with an overhead valve in-line twin engine. History Sunbeam Cycles was founded by John Marston, who was born in Ludlow, Shropshire, UK in 1836 of a minor landowning family. In 1851, aged 15, he was sent to Wolverhampton to be apprenticed to Edward Perry as a japanware manufacturer. At the age of 23 he left and set up his own japanning business making any and every sort of domestic article. He did so well that when Perry died in 1871 Marston bought Perry's business and amalgamated it with his own. In 1887 Marston began making bicycles and, on the suggestion of his wife Ellen, he adopted th ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Ayrshire
Ayrshire ( gd, Siorrachd Inbhir Àir, ) is a historic county and registration county in south-west Scotland, located on the shores of the Firth of Clyde. Its principal towns include Ayr, Kilmarnock and Irvine and it borders the counties of Renfrewshire and Lanarkshire to the north-east, Dumfriesshire to the south-east, and Kirkcudbrightshire and Wigtownshire to the south.

Dalrymple, East Ayrshire
Dalrymple ( sco, Drumple) is a village and parish in East Ayrshire, Scotland, lying in the Doon Valley on the north bank of the River Doon. The population is around 1,347.

Helicopter Flight Controls
A helicopter pilot manipulates the helicopter flight controls to achieve and maintain controlled aerodynamic flight. Changes to the aircraft flight control system transmit mechanically to the rotor, producing aerodynamic effects on the rotor blades that make the helicopter move in a deliberate way. To tilt forward and back (pitch) or sideways (roll) requires that the controls alter the angle of attack of the main rotor blades ''cyclically'' during rotation, creating differing amounts of lift (force) at different points in the cycle. To increase or decrease overall lift requires that the controls alter the angle of attack for all blades ''collectively'' by equal amounts at the same time, resulting in ascent, descent, acceleration and deceleration. A typical helicopter has three flight control inputs—the cyclic stick, the collective lever, and the anti-torque pedals. Depending on the complexity of the helicopter, the cyclic and collective may be linked together by a ''mixing uni ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Fejes
The Fejes was a Hungarian automobile, a utility vehicle manufactured in Budapest between 1923 and 1932 to a design by automotive engineer Jenő Fejes (1877-1951) by Fejes Lemezmotor és Gépgyár Rt.
