Certus Gearless Company
Certus Gearless Company Ltd. was a British manufacturer of automobiles. History The company was founded in London in 1907. The brand name was Certus. Only a few units were produced, and production ended in 1908. Models The smaller model used a two-cylinder engine. A larger model was propelled by a 4-cylinder engine from Aster with a displacement of 3000 cm³. The distinguishing feature of both models was the use of a friction drive A friction drive or friction engine is a type of transmission that utilises two wheels in the transmission to transfer power from the engine to the driving wheels.

Ateliers De Construction Mecanique L'Aster
L'Aster, Aster, Ateliers de Construction Mecanique l'Aster, was a French manufacturer of automobiles and the leading supplier of engines to other manufacturers from the late 1890s until circa 1910/12. Although primarily known as an engine mass manufacturer the company also produced chassis for coach-works and a complete range of components. Aster produced a range of engines including: stationary motors; electricity generators; automobile motors; marine engines and aero engines. There were air-cooled and water cooled Gasoline motors, Kerosene motors, and Gas Motors. Among the companies for which Aster produced engines and other parts were Ache Frères, Achilles, Argyll, Ariès, Aster-Newey, Automobiles Barré, Bolide, Belhaven, Bij 't Vuur, Century, Clément, Darracq, Dennis, Durham-Churchill, Ernst, Excelsior, Gladiator, Hanzer, Hoflack, Hurtu, Korn et Latil, Lacoste & Battmann, La Torpille, Lucerna, Newey Aster, Société Parisienne, Passy-Thellier, Pearson, Prun ...

Friction Drive
A friction drive or friction engine is a type of transmission that utilises two wheels in the transmission to transfer power from the engine to the driving wheels. The system is naturally a continuously variable transmission; by moving the two disks' positions, the output ratio changes continually. Although once used in early automobiles, today the system is most commonly used on scooters, mainly go-peds, in place of a chain and gear system. It is mechanically identical to a ball-and-disk integrator, but intended to handle higher torque levels. The system consists of two disks, normally metal, set at right angles to each other. One disk is connected to the engine, the other to the load. The load disk is positioned so that its outer rim is pressed against the driven disk, and normally has some sort of high-friction surface applied to the outer rim to improve torque transfer. In early systems, paper and leather was often used for this surface. One of the disks, normally the load ...

Vehicle Manufacture In London
A vehicle (from la, vehiculum) is a machine that transports people or cargo. Vehicles include wagons, bicycles, motor vehicles (motorcycles, cars, trucks, buses, mobility scooters for disabled people), railed vehicles (trains, trams), watercraft (ships, boats, underwater vehicles), amphibious vehicles (screw-propelled vehicles, hovercraft), aircraft (airplanes, helicopters, aerostats) and spacecraft.Halsey, William D. (Editorial Director): ''MacMillan Contemporary Dictionary'', page 1106. MacMillan Publishing, 1979. Land vehicles are classified broadly by what is used to apply steering and drive forces against the ground: wheeled, tracked, railed or skied. ISO 3833-1977 is the standard, also internationally used in legislation, for road vehicles types, terms and definitions.
