Partin Manufacturing Company (automobile Company)
The Partin Manufacturing Company was a brass era American automobile manufacturer, headquartered at 29 South LaSalle Street, Chicago, Illinois from 1913 to 1917. The Partin-Palmer automobile and Pioneer cyclecar were produced.Clymer, Floyd. ''Treasury of Early American Automobiles, 1877-1925'' (New York: Bonanza Books, 1950), p.151. History G. H. Partin, of the Partin Manufacturing Company, a large automobile sales agency in Chicago, joined in 1913 with the Palmer Motor Car Co. of Henry Palmer, formerly general manager of Cartercar. Palmer had formed his company from the assets of the Suburban Motor Car Company. They began by manufacturing cyclecars called the Pioneer, a Model 45 named the Partin, and a Model 38 named Partin-Palmer. The Partin model did not last to the end of 1913, and all models were subsequently called Partin-Palmers. The company first moved to Chicago to take over the Staver-Chicago automobile factory. Partin and Palmer were no longer with the company by ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Electric Starter
A starter (also self-starter, cranking motor, or starter motor) is a device used to rotate (crank) an internal-combustion engine so as to initiate the engine's operation under its own power. Starters can be electric, pneumatic, or hydraulic. The starter can also be another internal-combustion engine in the case, for instance, of very large engines, or diesel engines in agricultural or excavation applications. Internal combustion engines are feedback systems, which, once started, rely on the inertia from each cycle to initiate the next cycle. In a four-stroke engine, the third stroke releases energy from the fuel, powering the fourth (exhaust) stroke and also the first two (intake, compression) strokes of the next cycle, as well as powering the engine's external load. To start the first cycle at the beginning of any particular session, the first two strokes must be powered in some other way than from the engine itself. The starter motor is used for this purpose and it is not req ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Motor Vehicle Manufacturers Based In Illinois
An engine or motor is a machine designed to convert one or more forms of energy into motion (physics), mechanical energy. Available energy sources include potential energy (e.g. energy of the Earth's gravitational field as exploited in hydroelectric power generation), heat energy (e.g. Geothermal energy, geothermal), chemical energy, electric potential and nuclear energy (from nuclear fission or nuclear fusion). Many of these processes generate heat as an intermediate energy form; thus heat engines have special importance. Some natural processes, such as atmospheric convection cells convert environmental heat into motion (e.g. in the form of rising air currents). Mechanical energy is of particular importance in transportation, but also plays a role in many industrial processes such as cutting, grinding, crushing, and mixing. Mechanical heat engines convert heat into work via various thermodynamic processes. The internal combustion engine is perhaps the most common example of a ...

Manufacturing Companies Based In Chicago
Manufacturing is the creation or production of goods with the help of equipment, labor, machines, tools, and chemical or biological processing or formulation. It is the essence of the secondary sector of the economy. The term may refer to a range of human activity, from handicraft to high-tech, but it is most commonly applied to industrial design, in which raw materials from the primary sector are transformed into finished goods on a large scale. Such goods may be sold to other manufacturers for the production of other more complex products (such as aircraft, household appliances, furniture, sports equipment or automobiles), or distributed via the tertiary industry to end users and consumers (usually through wholesalers, who in turn sell to retailers, who then sell them to individual customers). Manufacturing engineering is the field of engineering that designs and optimizes the manufacturing process, or the steps through which raw materials are transformed into a final pro ...

Belt (mechanical)
A belt is a loop of flexible material used to link two or more rotating shafts mechanically, most often parallel. Belts may be used as a source of motion, to transmit power efficiently or to track relative movement. Belts are looped over pulleys and may have a twist between the pulleys, and the shafts need not be parallel. In a two pulley system, the belt can either drive the pulleys normally in one direction (the same if on parallel shafts), or the belt may be crossed, so that the direction of the driven shaft is reversed (the opposite direction to the driver if on parallel shafts). The belt drive can also be used to change the speed of rotation, either up or down, by using different sized pulleys. As a source of motion, a conveyor belt is one application where the belt is adapted to carry a load continuously between two points. History The mechanical belt drive, using a pulley machine, was first mentioned in the text of the ''Dictionary of Local Expressions'' by the Han ...

V-twin Engine
A V-twin engine, also called a V2 engine, is a two-cylinder piston engine where the cylinders are arranged in a V configuration and share a common crankshaft. The V-twin is widely associated with motorcycles, primarily installed longitudinally, though also transversely. They are also used in a variety of other land, air, and marine vehicles, as well as industrial applications. The V-twin design dates back to the late 1880s. Origins One of the first V-twin engines was built by Gottlieb Daimler in 1889. It was used as a stationary engine, for boats and in the Daimler Stahlradwagen ("steel-wheeled car"), Daimler's second car. The engine was also manufactured under licence in France by Panhard et Levassor. An early V-twin engined motorcycle was produced in November 1902 by the Princeps AutoCar Company in the United Kingdom. The following year, V-twin motorcycles were produced by Eclipse Motor & Cycle Co in the United Kingdom (the ''XL-ALL'' model), Glenn Curtiss in the United ...

Air-cooled Engine
Air-cooled engines rely on the circulation of air directly over heat dissipation fins or hot areas of the engine to cool them in order to keep the engine within operating temperatures. Air-cooled designs are far simpler than their liquid-cooled counterparts, which require a separate radiator, coolant reservoir, piping and pumps. Air-cooled engines are widely seen in applications where weight or simplicity is the primary goal. Their simplicity makes them suited for uses in small applications like chainsaws and lawn mowers, as well as small generators and similar roles. These qualities also make them highly suitable for aviation use, where they are widely used in general aviation aircraft and as auxiliary power units on larger aircraft. Their simplicity, in particular, also makes them common on motorcycles. Introduction Most modern internal combustion engines are cooled by a closed circuit carrying liquid coolant through channels in the engine block and cylinder head. A fl ...

Touring Car
Touring car and tourer are both terms for open cars (i.e. cars without a fixed roof). "Touring car" is a style of open car built in the United States which seats four or more people. The style was popular from the early 1900s to the 1930s. The cars used for touring car racing in various series since the 1960s, are unrelated to these early touring cars, despite sharing the same name. "Tourer" is used in British English for any open car. The term "all-weather tourer" was used to describe convertible (car), convertibles (vehicles that could be fully enclosed). A popular version of the tourer was the Torpedo (car), torpedo, with the hood/bonnet line level at the car's waistline giving the car a straight line from front to back. Touring car (U.S.) Design ''Touring car'' was applied in the U.S. to open cars (cars without a fixed roof, for example convertibles) that seat four or more people and have direct entrance to the tonneau (rear passenger area), although it has also been des ...

Beam Axle
A beam axle, rigid axle, or solid axle is a suspension (vehicle), dependent suspension design in which a set of wheels is connected laterally by a single beam or shaft. Beam axles were once commonly used at the rear wheels of a vehicle, but historically, they have also been used as front axles. In most automobiles, beam axles have been replaced with front (IFS) and rear independent suspensions (IRS). Implementation With a beam axle, the camber angle between the wheels is the same regardless of its location in the travel of the suspension. A beam axle's location in the fore and aft directions is constrained by one of several suspension components, including Trailing-arm suspension, trailing arms, semi-trailing arms, radius rods, and leaf springs. The lateral location can be constrained by a Panhard rod, a Scott Russell linkage, a Watt's linkage, or some other arrangement, most commonly by the leaf springs. Shock absorbers and either leaf springs, coil springs, or air suspension, ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Elliptic Spring
A leaf spring is a simple form of spring commonly used for suspension in wheeled vehicles. Originally called a ''laminated'' or ''carriage spring'', and sometimes referred to as a semi-elliptical spring, elliptical spring, or cart spring, it is one of the oldest forms of vehicle suspension. A leaf spring is one or more narrow, arc-shaped, thin plates that are attached to the axle and chassis in a way that allows the leaf spring to flex vertically in response to irregularities in the road surface. Lateral leaf springs are the most commonly used arrangement, running the length of the vehicle and mounted perpendicular to the wheel axle, but numerous examples of transverse leaf springs exist as well. Leaf springs can serve multiple suspension functions: location, springing, and to some extent damping as well, through interleaf friction. However, this friction is not well controlled, resulting in stiction and irregular suspension motions. For this reason, some manufacturers have us ...
