Simplex Motorcycle
Simplex Manufacturing Corporation was an American manufacturer that made motorcycles from 1935 to 1975. Between 1935 and 1960, Simplex made variations of the Simplex Servi-Cycle including the 1953–1960 Simplex Automatic. Simplex was the only motorcycle manufacturer located in the Deep South for many years, until Confederate Motorcycles began production. History Simplex was founded by Paul Treen (father of United States Congressman and Louisiana Governor David Conner Treen) in New Orleans, Louisiana in the late 1920s with an initial investment of $25. Treen had been a dealer in Harley-Davidson motorcycles and had Sales pitch, pitched them the idea of making a lightweight motorcycle for young riders. When Harley-Davidson rejected the idea, Treen decided to enter the market himself and designed his Servi-Cycle. The design was originally created in Baton Rouge before Treen moved the operation to New Orleans. The Simplex Servi-Cycle was introduced in 1935. Although Simplex Manufa ...

Simplex Servi Cycle At Barber Vintage Motorsports Museum
In geometry, a simplex (plural: simplexes or simplices) is a generalization of the notion of a triangle or tetrahedron to arbitrary dimensions. The simplex is so-named because it represents the simplest possible polytope in any given dimension. For example, * a 0-dimensional simplex is a point (mathematics), point, * a 1-dimensional simplex is a line segment, * a 2-dimensional simplex is a triangle, * a 3-dimensional simplex is a tetrahedron, and * a 4-dimensional simplex is a 5-cell. Specifically, a ''k''-simplex is a ''k''-dimensional polytope which is the convex hull of its ''k'' + 1 Vertex (geometry), vertices. More formally, suppose the ''k'' + 1 points u_0, \dots, u_k \in \mathbb^ are affinely independent, which means u_1 - u_0,\dots, u_k-u_0 are linearly independent. Then, the simplex determined by them is the set of points : C = \left\ This representation in terms of weighted vertices is known as the barycentric coordinate system. A regular simplex is a simpl ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Minibike
A minibike is a two-wheeled, motorized, off-highway recreational vehicle popularized in the 1960s and 1970s, but available continuously from a wide variety of manufacturers since 1959. Their off-highway nature and (in many countries) typically entirely off-road legal status differentiate minibikes from motorcycles and mopeds, and their miniature size differentiates them from dirt bikes. Traditionally, minibikes have a four-stroke, horizontal crankshaft engine, single- or two-speed centrifugal clutch transmissions with chain final-drive, 4" or 6" wheels and a low frame/seat height with elevated handlebars. Commercially available minibikes are usually equipped with small engines commonly found elsewhere on utilitarian equipment such as garden tillers History While the minibike had precursors in machines such as the Doodle Bug and Cushman Scooters, which share smaller wheels, tubular-steel frames, and air-cooled, single-cylinder engines, those vehicles had larger seat heights a ...

Vehicle Manufacturing Companies Established In 1935
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. History * The oldest boats found by archaeological excavation are logboats, with the oldest logboat found, the Pesse canoe found in a bog in the Netherlands, being carbon dated to 8040 - ...

Bonhams
Bonhams is a privately owned international auction house and one of the world's oldest and largest auctioneers of fine art and antiques. It was formed by the merger in November 2001 of Bonhams & Brooks and Phillips Son & Neale. This brought together two of the four surviving Georgian auction houses in London, Bonhams having been founded in 1793, and Phillips in 1796 by Harry Phillips, formerly a senior clerk to James Christie. Today, the amalgamated business handles art and antiques auctions. It operates two salerooms in London—the former Phillips sale room at 101 New Bond Street, and the old Bonham's sale room at the Montpelier Galleries in Montpelier Street, Knightsbridge—with a smaller sale room in Edinburgh. Sales are also held around the world in New York, Hong Kong, Los Angeles, Paris, San Francisco, Sydney, and Singapore. Bonhams holds more than 280 sales a year in more than 60 collecting areas, including Asian art, Pictures, motor cars and jewelry. Bonham ...

Spark Plug
A spark plug (sometimes, in British English, a sparking plug, and, colloquially, a plug) is a device for delivering electric current from an ignition system to the combustion chamber of a spark-ignition engine to ignite the compressed fuel/air mixture by an electric spark, while containing combustion pressure within the engine. A spark plug has a metal threaded shell, electrically isolated from a central electrode by a ceramic insulator. The central electrode, which may contain a resistor, is connected by a heavily insulated wire to the output terminal of an ignition coil or magneto. The spark plug's metal shell is screwed into the engine's cylinder head and thus electrically grounded. The central electrode protrudes through the porcelain insulator into the combustion chamber, forming one or more spark gaps between the inner end of the central electrode and usually one or more protuberances or structures attached to the inner end of the threaded shell and designated the ''side ...

Dual Ignition
Dual Ignition is a system for spark-ignition engines, whereby critical ignition components, such as spark plugs and magnetos, are duplicated. Dual ignition is most commonly employed on aero engines,Crane, Dale: ''Dictionary of Aeronautical Terms, third edition'', page 177. Aviation Supplies & Academics, 1997. Aviation Publishers Co. Limited, ''From the Ground Up'', (27th revised edition), page 67, and is sometimes found on cars and motorcycles. Dual ignition provides two advantages: redundancy in the event of in-flight failure of one ignition system; and more efficient burning of the fuel-air mixture within the combustion chamber. In aircraft and gasoline-powered fire fighting equipment, redundancy is the prime consideration, but in other vehicles the main targets are efficient combustion and meeting emission law requirements. Efficiency A dual ignition system will typically provide that each cylinder has twin spark plugs, and that the engine will have at least two ignition ...

Magneto
A magneto is an electrical generator that uses permanent magnets to produce periodic pulses of alternating current. Unlike a dynamo, a magneto does not contain a commutator to produce direct current. It is categorized as a form of alternator, although it is usually considered distinct from most other alternators, which use field coils rather than permanent magnets. Hand-cranked magneto generators were used to provide ringing current in telephone systems. Magnetos were also adapted to produce pulses of high voltage in the ignition systems of some gasoline-powered internal combustion engines to provide power to the spark plugs. Use of such ignition magnetos for ignition is now limited mainly to engines without a low-voltage electrical system, such as lawnmowers and chainsaws, and to aircraft engines, in which keeping the ignition independent of the rest of the electrical system ensures that the engine continues running in the event of alternator or battery failure. For redundancy ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Smithsonian Institution
The Smithsonian Institution ( ), or simply the Smithsonian, is a group of museums and education and research centers, the largest such complex in the world, created by the U.S. government "for the increase and diffusion of knowledge". Founded on August 10, 1846, it operates as a trust instrumentality and is not formally a part of any of the three branches of the federal government. The institution is named after its founding donor, British scientist James Smithson. It was originally organized as the United States National Museum, but that name ceased to exist administratively in 1967. Called "the nation's attic" for its eclectic holdings of 154 million items, the institution's 19 museums, 21 libraries, nine research centers, and zoo include historical and architectural landmarks, mostly located in the District of Columbia. Additional facilities are located in Maryland, New York, and Virginia. More than 200 institutions and museums in 45 states,States without Smithsonian ...

Southern United States
The Southern United States (sometimes Dixie, also referred to as the Southern States, the American South, the Southland, or simply the South) is a geographic and cultural region of the United States of America. It is between the Atlantic Ocean and the Western United States, with the Midwestern and Northeastern United States to its north and the Gulf of Mexico and Mexico to its south. Historically, the South was defined as all states south of the 18th century Mason–Dixon line, the Ohio River, and 36°30′ parallel.The South . ''Britannica.com''. Retrieved June 5, 2021.

Western Auto
Western Auto Supply Company—known more widely as Western Auto—was a specialty retail chain of stores that supplied automobile parts and accessories. It operated approximately 1200 stores across the United States. It was started in 1909 in Kansas City, Missouri, by George Pepperdine and Don Abnor Davis. Pepperdine later founded Pepperdine University. Western Auto was bought by Beneficial Corporation in 1961; Western Auto's management led a leveraged buyout in 1985, leading three years later to a sale to Sears. Sears sold most of the company to Advance Auto Parts in 1998, and by 2003, the resulting merger had led to the end of the Western Auto brand and its product distribution network. History Western Auto originally started as a mail order business for replacement auto parts. The first retail store was established in 1921, and grew quickly as automobiles became increasingly more common. At one point, there were over 1,200 company-owned stores nationwide, usuall ...
