Ascot-Pullin 500
The Ascot-Pullin 500 was a motorcycle made by Ascot-Pullin Motorcycles in Letchworth, Hertfordshire in 1928. As an updated version of the Pullin motor bicycle of 1919, the Ascot-Pullin 500 overhead valve single was the first time hydraulic brakes were used on a motorcycle. History In 1919, British inventor Cyril Pullin and Stanley L. Groom produced the Pullin motor bicycle, a wheeled machine that included a novel two-stroke engine and extensive manufacture use of steel pressings that anticipated developments by British motorcycle manufacturer Ariel Motorcycles in the late 1950s and Japanese motorcycle manufacturers in 1960s. The bicycle was patented in 1920. Since 1920, Pullin had been working with Stanley Groom to develop and patent a two-stroke motorcycle with a unique design of pressed sheet metal frame and forks. After working on a range of other inventions including the Ascot, Pullin teamed up with Groom again to further develop their ideas and patent the Ascot Pull ...

Ariel Motorcycles
Ariel Motorcycles was a British maker of bicycles and then motorcycles in Bournbrook, Birmingham. It was an innovator in British motorcycling, part of the Ariel marque. The company was sold to BSA in 1951 but the brand survived until 1967. Influential Ariel designers included Val Page and Edward Turner. The last motorcycle-type vehicle to carry the Ariel name was a short-lived three-wheel tilting moped in 1970. Ariel made bicycles before making motorcycles, and also made cars. Car production began in 1902, moved to Coventry in 1911 and ceased in 1925. The 'Ariel' name was reused in 1999 for the formation of Ariel Ltd, a sports car producer. History Bicycles and early motorised vehicles The original company was established in 1870 by James Starley and William Hillman. They built wire-spoke wheels under the first British patent; this allowed them also to build a lighter "penny farthing" bicycle which they named 'Ariel' (the spirit of the air). They put the name on the fact ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

United States Department Of Transportation
The United States Department of Transportation (USDOT or DOT) is one of the executive departments of the U.S. federal government. It is headed by the secretary of transportation, who reports directly to the President of the United States and is a member of the president's Cabinet. The department's mission is "to develop and coordinate policies that will provide an efficient and economical national transportation system, with due regard for need, the environment, and the national defense." History Prior to the creation of the Department of Transportation, its functions were administered by the under secretary of commerce for transportation. In 1965, Najeeb Halaby, administrator of the Federal Aviation Agency (predecessor to the Federal Aviation Administration, FAA), suggested to President Lyndon B. Johnson that transportation be elevated to a cabinet-level post, and that the FAA be folded into the DOT. It was established by Congress in the Department of Transportation Act ...

National Highway Traffic Safety Administration
The National Highway Traffic Safety Administration (NHTSA ) is an agency of the U.S. federal government, part of the Department of Transportation. It describes its mission as "Save lives, prevent injuries, reduce vehicle-related crashes" related to transportation safety in the United States. NHTSA is charged with writing and enforcing Federal Motor Vehicle Safety Standards as well as regulations for motor vehicle theft resistance and fuel economy, as part of the Corporate Average Fuel Economy (CAFE) system. FMVSS 209 was the first standard to become effective on March 1, 1967. NHTSA cannot licenses vehicle manufacturers and importers, allows or blocks the import of vehicles and safety-regulated vehicle parts, administers the vehicle identification number (VIN) system, develops the anthropomorphic dummies used in U.S. safety testing as well as the test protocols themselves, and provides vehicle insurance cost information. The agency has asserted preemptive regulatory authori ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Vincent Black Prince
The Vincent Black Prince was a British motorcycle made between 1954 and 1955 by Vincent Motorcycles. A year before the factory closed in 1955, Vincent produced the enclosed range of Vincent Black Knight and Black Prince. Philip Vincent described it as a "two-wheeled Bentley", and the enclosed Vincents attracted a lot of attention at the November 1954 Earls Court show. Quality problems with early production of the glass-fibre mouldings necessitated a replacement supplier causing delays. The last Black Prince left the Vincent production line on Friday, 16 December 1955. Development Falling sales of the Series C Vincent motorcycles during 1952 and 1953 was partly attributed to dated styling, so Philip Vincent sought to update the range and development began on what were to become the Series D machines. The main changes were redesigned frame components, resited oil tank, larger fuel tank, smaller diameter wheels, one-less rear brake drum, new design carburettors and updated electric ...

Ariel Leader
The Ariel Leader was a British motorcycle produced by Ariel Motorcycles between 1958 and 1965. A radical design, the Leader was fully enclosed with an integral windscreen and was the first British motorcycle to have optional flashing indicators. Ariel could not compete against Japanese imports and the last Ariel Leader was produced when the company closed in 1965. Development Designed by Val Page and Bernard Knight, The Ariel Leader featured a 250 cc two-stroke engine suspended from a monocoque 'backbone' fabricated from 20-gauge pressed steel panels. The fuel tank was hidden inside this structure and accessed by lifting the hinged dual seat. A dummy petrol tank was used for storage and was large enough to fit a spare crash helmet. It was the fully enclosed bodywork (first developed by Phil Vincent for the innovative Vincent Black Prince) that was most prominent, as none of the working parts of the motorcycle were visible. As well as a full body, the standard Leader f ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Parragon
Parragon Books Ltd, a United Kingdom publishing company, was formed in 1988 by friends Guy Parr and Paul Anderson. In 2001, it became part of D. C. Thomson & Co. History Parragon began its early years by developing business through overstocks and reprinting dormant titles from key publishers archives such as Penguin Books and HarperCollins. In 1992, Parragon shifted focus through a trial bargain book table placed in Asda's grocery store in Nuneaton. Following the trial's success, Parragon extended their bargain book strategy to other key retailers such as Tesco and Woolworths. As sales increased, these retailers employed Parragon to distribute titles from other major publishers. The distribution business continued until the mid to late 1990s before Parragon decided to concentrate on their own publishing. The distribution business was offloaded to Cork International, who continued to service the grocers until 2004 before their demise. In the late 1990s, Parragon's publishing b ...

Four-stroke Engine
A four-stroke (also four-cycle) engine is an internal combustion (IC) engine in which the piston completes four separate strokes while turning the crankshaft. A stroke refers to the full travel of the piston along the cylinder, in either direction. The four separate strokes are termed: #Intake: Also known as induction or suction. This stroke of the piston begins at top dead center (T.D.C.) and ends at bottom dead center (B.D.C.). In this stroke the intake valve must be in the open position while the piston pulls an air-fuel mixture into the cylinder by producing vacuum pressure into the cylinder through its downward motion. The piston is moving down as air is being sucked in by the downward motion against the piston. #Compression: This stroke begins at B.D.C, or just at the end of the suction stroke, and ends at T.D.C. In this stroke the piston compresses the air-fuel mixture in preparation for ignition during the power stroke (below). Both the intake and exhaust valves are close ...

Ascot (1928 Automobile)
The Ascot was an English automobile, the brainchild of Cyril Pullin (who also produced Ascot-Pullin motorcycles at the same time), that was manufactured between 1928 and 1930 in Letchworth, Hertfordshire. The factory had previously been used by Phoenix. The car was based largely on the Hungarian Fejes, with chassis and 10 hp engine assembled from welded steel pressings. The lack of castings was intended to keep the price low, at approximately 125 pounds, but due to lack of finance it never went into production. A larger car, the Ascot Gold Cup Six with a 2423 cc six cylinder engine possibly made by Continental, 3-speed gearbox and servo brakes did become a reality and a few production cars were made. It was advertised as being available as a 2-seat sports, coupé or fabric saloon. It had no connection with the 1904 Ascot car.

Motorcycle Fork
A motorcycle fork connects a motorcycle's front wheel and axle to its frame, typically via a yoke, also known as a triple clamp, which consists of an upper yoke joined to a lower yoke via a steering stem, a shaft that runs through the steering head, creating the steering axis. Most forks incorporate the front suspension and front brake, and allow the front wheel to rotate about the steering axis so that the bike may be steered. Most handlebars attach to the top clamp in various ways, while clip-on handlebars clamp to the fork tubes, either just above or just below the upper triple clamp. The fork and its attachment points on the frame establish the critical geometric parameters of rake and trail, which play a major role in defining how a motorcycle handles and dives during braking. While the standard telescopic fork arrangement is found with few major differences among mainstream street motorcycles since the 1970s, historically there have been many variations, including trailin ...

Motorcycle Frame
A motorcycle frame is a motorcycle's core structure. It supports the engine, provides a location for the steering and rear suspension, and supports the rider and any passenger or luggage. Also attached to the frame are the fuel tank and battery. At the front of the frame is found the steering head tube that holds the pivoting front fork, while at the rear there is a pivot point for the swingarm suspension motion. Some motorcycles include the engine as a load-bearing stressed member; while some other bikes do not use a single frame, but instead have a front and a rear subframe attached to the engine. Materials In the early days, motorcycles were little more than motorised bicycles, and consequently frames were tubular steel. While the use of steel tubing is still common, in modern times other materials, such as titanium, aluminium, magnesium, and carbon-fibre, along with composites of these materials, are now used. As different motorcycles have varying design parameters (such as ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
