Allen Norton (motorcycle)
Allen Norton is a defunct British company that supplied replicas of 350 and 500 cc Norton Manx road racing motorcycles. The company was run by Bernie Allen in Great Bedwyn, near Marlborough, Wiltshire. The company started to build replicas of the famous Norton Manx racers in 1990, based on the final 1961 Manx. Allen had been given the rights in 1989 after the death of Norton tuner Ray Petty and had received special permission to use the name "Norton" in England. Except for the magnetos, all the components used were of new manufacture. The engines were supplied by Summerfield Engineering of Derbyshire, the frames came from Goodman Engineering and were made from Reynolds 531 tubing. The machines were fitted with a 5-speed gearbox and a belt primary drive. (The originals used a 4-speed gearbox and chain primary drive.) Although the original Manx machines were pure racers, Allen fitted a speedometer, horn and brake light so the machines could be ridden on the road. The machines ...

Norton Manx
The Norton Manx or Manx Norton is a British racing motorcycle that was made from 1947 to 1962 by Norton Motors Ltd. Norton had contested every Isle of Man TT race from the inaugural 1907 event through into the 1970s, a feat unrivalled by any other manufacturer, and the development and honing of the Manx racing motorcycle was another step in this racing achievement. New Manx Nortons, built to various specifications are still available to buy new, from various suppliers around the world. These should not be confused with Norton production motorcycles even though they suit different categories and definitions of Classic Motorcycle Racing and Historic Motorcycle Racing in different countries around the world. Norton's first use of the name 'Manx' was applied to the 'Manx Grand Prix' model available from 1936 to 1940, a special racing version of their 'International' roadster, with telescopic forks and a plunger rear suspension, magnesium for the crankcases and cambox, and no prov ...

Marlborough, Wiltshire
Marlborough ( , ) is a market town and Civil parishes in England, civil parish in the England, English Counties of England, county of Wiltshire on the A4 road (England), Old Bath Road, the old main road from London to Bath, Somerset, Bath. The town is on the River Kennet, 24 miles (39 km) north of Salisbury and 10 miles (16 km) southeast of Swindon. History The earliest sign of human habitation is the Marlborough Mound, a prehistoric tumulus in the grounds of Marlborough College. Recent radiocarbon dating has found it to date from about 2400 BC. It is of similar age to the larger Silbury Hill about west of the town. Legend has it that the Mound is the burial site of Merlin (wizard), Merlin and that the name of the town comes from Merlin's Tumulus, Barrow. More plausibly, the town's name possibly derives from the medieval term for chalky ground "marl"—thus, "town on chalk". However more recent research, from geographer John Everett-Heath, identifies the original O ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Norton Motorcycle Company
The Norton Motorcycle Company (formerly Norton Motorcycles.) is a brand of motorcycles headquartered in Solihull, West Midlands, (originally based in Birmingham), England. For some years around 1990, the rights to use the name on motorcycles were owned by North American financiers. Currently it is owned by Indian motorcycle giant TVS Motor Company. The business was founded in 1898 as a "fittings and parts for the two-wheel trade" manufacturer.Holliday, Bob, ''Norton Story'', Patrick Stephens, 1972, p.11. By 1902 the company had begun manufacturing motorcycles with bought-in engines. In 1908 a Norton-built engine was added to the range. This began a long series of production of single and eventually twin-cylinder motorcycles, and a long history of racing involvement. During the Second World War Norton produced almost 100,000 of the military Model 16 H and Big 4 sidevalve motorcycles. Associated Motor Cycles bought the company in 1953. It was reformed as Norton-Vil ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Ignition Magneto
An ignition magneto (also called a high-tension magneto) is an older type of ignition system used in spark-ignition engines (such as petrol engines). It uses a magneto and a transformer to make pulses of high voltage for the spark plugs. The older term "high-tension" means "high-voltage". Design A simple magneto (an electrical generator using permanent magnets) is able to produce relatively low voltage electricity, however it is unable to produce the high voltages required by a spark plug as used in most modern engines (aside from diesel engines). An ''ignition magneto'' also includes an electrical transformer, which converts the electricity to a higher voltage (with the trade-off being a corresponding reduction in the output electric current, current). As the points begin to open, point spacing is initially such that the voltage across the primary coil would arc across the points. A capacitor is placed across the points which absorbs the energy stored in the leakage inductanc ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Gearbox
A transmission (also called a gearbox) is a mechanical device invented by Louis Renault (who founded Renault) which uses a gear set—two or more gears working together—to change the speed, direction of rotation, or torque multiplication/reduction in a machine. Transmissions can have a single fixed-gear ratio, multiple distinct gear ratios, or continuously variable ratios. Variable-ratio transmissions are used in all sorts of machinery, especially vehicles. Applications Early uses Early transmissions included the right-angle drives and other gearing in windmills, horse-powered devices, and steam-powered devices. Applications of these devices included pumps, mills and hoists. Bicycles Bicycles traditionally have used hub gear or Derailleur gear transmissions, but there are other more recent design innovations. Automobiles Since the torque and power output of an internal combustion engine (ICE) varies with its rpm, automobiles powered by ICEs require multiple ...

Belt Drive
A belt is a loop of flexible material used to link two or more rotating shafts mechanically, most often parallel. Belts may be used as a source of motion, to transmit power efficiently or to track relative movement. Belts are looped over pulleys and may have a twist between the pulleys, and the shafts need not be parallel. In a two pulley system, the belt can either drive the pulleys normally in one direction (the same if on parallel shafts), or the belt may be crossed, so that the direction of the driven shaft is reversed (the opposite direction to the driver if on parallel shafts). The belt drive can also be used to change the speed of rotation, either up or down, by using different sized pulleys. As a source of motion, a conveyor belt is one application where the belt is adapted to carry a load continuously between two points. History The mechanical belt drive, using a pulley machine, was first mentioned in the text of the ''Dictionary of Local Expressions'' by the Han ...

Chain Drive
Chain drive is a way of transmitting mechanical power from one place to another. It is often used to convey power to the wheels of a vehicle, particularly bicycles and motorcycles. It is also used in a wide variety of machines besides vehicles. Most often, the power is conveyed by a roller chain, known as the drive chain or transmission chain, passing over a sprocket, with the teeth of the gear meshing with the holes in the links of the chain. The gear is turned, and this pulls the chain putting mechanical force into the system. Another type of drive chain is the Morse chain, invented by the Morse Chain Company of Ithaca, New York, United States. This has inverted teeth. Sometimes the power is output by simply rotating the chain, which can be used to lift or drag objects. In other situations, a second gear is placed and the power is recovered by attaching shafts or hubs to this gear. Though drive chains are often simple oval loops, they can also go around corners by placing ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Doug Hele
