Harley-Davidson Model 7D
The Harley-Davidson Model 7D of 1911 was the first successful v-twin from Harley-Davidson, inaugurating a motorcycle engine configuration that has continued unbroken from the Milwaukee motor company ever since. In 1909, Harley had made a few examples (27 units) of another v-twin, but the design was flawed and they did not try again until two years later. In 1911, 5,625 Model 7Ds were manufactured.Statnekov (1998) p. 117 The Model 7D's motor was the F-head IOE engine, in use until 1929.de Cet (2001) p. 110 It sold for US$300, which with inflation would be $ in today's currency. Ignition was via a magneto, and the engine was started using bicycle-style pedals. Instead of a conventional clutch, a pulley belt tensioner could be moved, allowing the leather drive belt to slip. Touting its effective muffler, Harley-Davidson advertised the 7D, and the other Harleys of this era, as "The Silent Gray Fellow." The latter moniker was also in reference to William S. Harley, who was known ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Hemmings Motor News
''Hemmings Motor News'' (HMN) is a monthly magazine catering to traders and collectors of antique, classic, and exotic sports cars. It is the largest and oldest publication of its type in the United States, with sales of 215,000 copies per month, and is best known for its large classified advertising sections.

Sears Dreadnought
Sears Dreadnought was a motorcycle sold by Sears in the 1910s. The motorcycle featured a V-twin made by Spacke. It was sourced from Spacke's cyclecar and had . This engine was also used by Dayton, Eagle, Minneapolis and Crawford. In addition to the internal combustion engine, it also had foot-pedals like a regular bicycle. (This was for getting the engine started as the kick start had not been invented yet.) The motorcycle was designed for Sears in conjunction with Excelsior Company of N. Sangamon Street, Chicago. They put together popular components and features of the period including the Spacke V-twin engine, a Schebler carburetor, Musselman hub, chain drive, etc. It was offered with various options such as a two-speed hub and a lightning package. Sears sold the motorcycle like its other products via mail order for $250 in 1913 ($ in dollars ). People would shop out of large catalog of thousands of items rather than the local store, then the product would be delivered to the ...

Thor Model U
Thor Model U was a motorcycle that debuted in the 1910s with a 7 hp V-twin in the Thor marque of Aurora Automatic Machinery Company of Illinois. The 1913 model came with a 61 ci (cubic inch) V-twin engine, with the V at an angle of 50 degrees. In 1914 the engine size was increased from 61ci to 76.25ci The motorcycle had chain drive with clutch and was overall a bicycle configuration with two handle bars and seat above a frame which housed the engine and connected the front and back. The V-twin has an angle of 50 degrees. By 1916, the Model U was essentially the "flagship" of the Thor lineup with a large 50 degree V-twin with mechanical valves, a magneto ignition, and a three speed transmission. These kind of features were improvements over typically features of the day like a single-cylinder engine, battery start, and two speed or even single speed;they were much closer to their bicycle origins they had just birthed from in the previous decade. The motorcycle was fast for its day set ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Single Cylinder Engine
A single-cylinder engine, sometimes called a thumper, is a piston engine with one cylinder. This engine is often used for motorcycles, motor scooters, go-karts, all-terrain vehicles, radio-controlled vehicles, portable tools and garden machinery (such as lawnmowers, cultivators, and string trimmers). Single-cylinder engines are made both as 4-strokes and 2-strokes. Characteristics Compared with multi-cylinder engines, single-cylinder engines are usually simpler and compact. Due to the greater potential for airflow around all sides of the cylinder, air cooling is often more effective for single cylinder engines than multi-cylinder engines. This reduces the weight and complexity of air-cooled single-cylinder engines, compared with liquid-cooled engines. Drawbacks of single-cylinder engines include a more pulsating power delivery through each cycle and higher levels of vibration. The uneven power delivery means that often a single-cylinder engine requires a heavier flywheel than a ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Clutch
A clutch is a mechanical device that engages and disengages power transmission, especially from a drive shaft to a driven shaft. In the simplest application, clutches connect and disconnect two rotating shafts (drive shafts or line shafts). In these devices, one shaft is typically attached to an engine or other power unit (the driving member), while the other shaft (the driven member) provides output power for work. Typically the motions involved are rotary, but linear clutches also exist. In a motor vehicle, the clutch acts as a mechanical linkage between the engine and transmission, and briefly disconnects, or separates the engine from the transmission system. This disconnects the drive wheels whenever the clutch pedal is depressed, allowing the driver to smoothly change gears. In a torque-controlled drill, for instance, one shaft is driven by a motor, and the other drives a drill chuck. The clutch connects the two shafts so they may be locked together and spin at the ...

Guggenheim Las Vegas
The Solomon R. Guggenheim Foundation is a nonprofit organization founded in 1937 by philanthropist Solomon R. Guggenheim and his long-time art advisor, artist Hilla von Rebay. The foundation is a leading institution for the collection, preservation, and research of modern and contemporary art and operates several museums around the world. The first museum established by the foundation was The Museum of Non-Objective Painting, in New York City. This became The Solomon R. Guggenheim Museum in 1952, and the foundation moved the collection into its first permanent museum building, in New York City, in 1959. The foundation next opened the Peggy Guggenheim Collection in Venice, Italy, in 1980. Its international network of museums expanded in 1997 to include the Guggenheim Museum Bilbao in Bilbao, Spain, and it expects to open a new museum, Guggenheim Abu Dhabi, in the United Arab Emirates after its construction is completed.

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 ...
