ABC Motorcycles
ABC motorcycles was a British motorcycle manufacturer established in 1914 by Ronald Charteris in London. Several British motorcycle firms started up with the name "ABC", including Sopwith Aviation Company, Sopwith. The All British Engine Company Ltd. of London was founded in 1912 and later changed to ABC Motors Ltd. With chief engineer Granville Bradshaw, Charteris built a range of engines throughout the First World War. From 1913 ABC produced motorcycle engines. In 1918, ABC made a motorcycle with a 400 cc flat-twin engine mounted with its cylinders across the frame, several years before History of BMW motorcycles, BMW adapted the design. Bradshaw challenged BMW's use of his patented design in 1926. In 1919 ABC also produced the Scootamota – an early Scooter (motorcycle), motor scooter. The company stopped producing motorcycles after 1923 because of competition from cheaper manufacturers. Development ABC had always had a close association with the Sopwith Aviation C ...

Granville Bradshaw
Granville Eastwood Bradshaw Order of the British Empire, OBE, Royal Aeronautical Society, AFRAeS (1887–1969) was an English engineer and inventor who designed motorcycle, auto, and aero-engines. History Bradshaw was born in Preston, Lancashire in 1887 as the son of William and Annie Bradshaw. His father was a jeweler and optician. Bradshaw's early work was involved with the early pioneers of flight, which led him to become an expert on stressing. He designed the Star Monoplane including the engine for Star Aircraft when he was 19, which he later flew. He then started to work on aero-engines and was the co-founder of the All-British Engine Company (later ABC Motors then Walton Motors). The ABC radial aero-engines designed and built during the First World War were extremely advanced and the government placed large orders for the ABC Dragonfly, Dragonfly. A number of aircraft were designed to use the Dragonfly, but the engines were plagued by problems and failed to live up to t ...

Four-stroke
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 a partial vacuum (negative pressure) in the cylinder through its downward motion. #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 closed during this stage. #Combustion: Also known as power or ignition. This is ...

Motorcycle Manufacturers Of The United Kingdom
A motorcycle (motorbike, bike; uni (if one-wheeled); trike (if three-wheeled); quad (if four-wheeled)) is a lightweight private 1-to-2 passenger personal motor vehicle steered by a handlebar from a saddle-style seat. Motorcycle designs vary greatly to suit a range of different purposes: long-distance travel, commuting, cruising, sport (including racing), and off-road riding. Motorcycling is riding a motorcycle and being involved in other related social activities such as joining a motorcycle club and attending motorcycle rallies. The 1885 Daimler Reitwagen made by Gottlieb Daimler and Wilhelm Maybach in Germany was the first internal combustion, petroleum-fueled motorcycle. In 1894, Hildebrand & Wolfmüller became the first series production motorcycle. Globally, motorcycles are comparable numerically to cars as a method of transport: in 2021, approximately 58.6 million new motorcycles were sold around the world, while 66.7 million cars were sold over the same period.

ABC Motors
ABC Motors Limited ("All British (Engine) Company") of Hersham, Surrey, England was a manufacturer of cars, aircraft, motor scooters, and engines for road and air. Established by Ronald Charteris in Hersham, Surrey in 1912, its chief designer was the young and talented Granville Bradshaw.Lumsden 2003, p. 51. It was absorbed into Vickers in 1951 and the factory finally closed in the 1970s. Last occupied by Ian Allan Publishing as Hersham's Riverdene Industrial Estate, the factory was demolished around 2017-2018 and redeveloped as a Lidl supermarket (opened February 2019) with flats above. Products The ABC radial aero engines of the World War I period were extremely advanced for their time, and were initially thought to be very promising indeed. Unfortunately they were all more or less plagued by problems – and although a number of types for the Royal Air Force were designed around ABC engines (especially the ill-fated ''Dragonfly'') none saw squadron service with the RAF. ...

Villiers Engineering
Villiers Engineering was a manufacturer of motorcycles and cycle parts, and an engineering company based in Villiers Street, Wolverhampton, England. Early history In the 1890s John Marston (Industrialist), John Marston's Sunbeam Cycles, Sunbeam had become extremely successful by relying on high quality of production and finish. But Marston was dissatisfied with the pedals on his machines, which he bought in. In 1890 he dispatched his son Charles to the US on a selling trip, but included in his instructions that Charles must discuss pedal engineering with Pratt and Whitney in Hartford, Connecticut and come back with a high-class pedal and the machinery for making it. Charles said that the Villiers Engineering Co. was "the ultimate fruit" of his trip to the US, being impressed by the production system and the labour-saving devices. He pointed out that "it was not possible to develop these at Sunbeamland, which had long been working on another plan, but it was possible to start th ...

Band Brake
A band brake is a primary or secondary brake, consisting of a band of friction material that tightens concentrically around a cylindrical piece of equipment or train wheel to either prevent it from rotating (a static or "holding" brake), or to slow it (a dynamic brake). Uses Band brakes were common on winch drums and chain saws and is also used for some bicycle brakes. Band brakes were commonly used to control the winding drum on railway inclines that lowered loaded wagons while raising empty ones over a steep slope. A former application was the locking of gear rings in epicyclic gearing. In modern automatic transmissions this task has been largely taken over by multiple-plate clutches or multiple-plate brakes. Features A band brake is a flexible band which warps around part or all of the outside surface of a wheel or drum. One end of the band is anchored in place, while the other is attached to a lever. Pressing on the lever brings the band into contact with the su ...

Overhead Valve
An overhead valve engine, abbreviated (OHV) and sometimes called a pushrod engine, is a piston engine whose valves are located in the cylinder head above the combustion chamber. This contrasts with flathead (or "sidevalve") engines, where the valves were located below the combustion chamber in the engine block. Although an overhead camshaft (OHC) engine also has overhead valves, the common usage of the term "overhead valve engine" is limited to engines where the camshaft is located in the engine block. In these traditional OHV engines, the motion of the camshaft is transferred using pushrods (hence the term "pushrod engine") and rocker arms to operate the valves at the top of the engine. However, some designs have the camshaft in the cylinder head but still sit below or alongside the valves (the Ford CVH and Opel CIH are good examples), so they can essentially be considered overhead valve designs. Some early intake-over-exhaust engines used a hybrid design combining elemen ...

IOE Engine
The intake/inlet over exhaust, or "IOE" engine, known in the US as F-head, is a four-stroke internal combustion engine whose valvetrain comprises OHV inlet valves within the cylinder head and exhaust side-valves within the engine block.V.A.W Hillier: ''Fundamentals of Motor Vehicle Technology'', 4th edition, Standly Thornes, Cheltenham 1991, , p. 39+40 IOE engines were widely used in early motorcycles, initially with the inlet valve being operated by engine suction instead of a cam-activated valvetrain. When the suction-operated inlet valves reached their limits as engine speeds increased, the manufacturers modified the designs by adding a mechanical valvetrain for the inlet valve. A few automobile manufacturers, including Willys, Rolls-Royce and Humber also made IOE engines for both cars and military vehicles. Rover manufactured inline four and six cylinder engines with a particularly efficient version of the IOE induction system. A few designs with the reverse system, exhaus ...

Gnome & Rhone
A gnome () is a mythological creature and diminutive spirit in Renaissance magic and alchemy, introduced by Paracelsus in the 16th century and widely adopted by authors, including those of modern fantasy literature. They are typically depicted as small humanoids who live underground. Gnome characteristics are reinterpreted to suit various storytellers and artists. Paracelsus's gnome is recognized to have derived from the German miners' legend about or , the "metallurgical or mineralogical demon", according to Georg Agricola (1530), also called (literal Latinization of ''Bergmännlein'', "mountain manikin") by Agriocola in a later work (1549), and described by other names such as (sing. ; Latinization of German ). Agricola recorded that, according to the legends of that profession, these mining spirits acted as miming and laughing pranksters who sometimes threw pebbles at miners, but could also reward them by depositing a rich vein of silver ore. Paracelsus also called his ...
