Willamette Locomotive
The Willamette locomotive was a geared steam locomotive of the Shay locomotive type, built by the Willamette Iron and Steel Works of Portland, Oregon. After key patents on the Shay locomotive had expired, it was possible for other manufacturers to produce Shay "clones". The Willamette locomotive was very similar to a Shay, but had many differences, as the company that made them intended on making an "improved Shay", even though the "Pacific Coast Shay", later made by Lima, took up many of the features on the Willamette. The differences were: *All Willamettes were equipped with superheaters, while Shays usually were not. *The boiler parts were riveted together, instead of being bolted together. *The Willamette locomotive used Walschaerts valve gear driving piston valves, while the Shay mainly used Stephenson valve gear driving slide valves. *The truck design was completely redone and rode much smoother. *The rear cylinder on the Willamette was facing the same direction as ...

Slide Valve
The slide valve is a rectilinear valve used to control the admission of steam into and emission of exhaust from the cylinder of a steam engine. Use In the 19th century, most steam locomotives used slide valves to control the flow of steam into and out of the cylinders. In the 20th century, slide valves were gradually superseded by piston valves, particularly in engines using superheated steam. There were two reasons for this: * With piston valves, the steam passages can be made shorter. This reduces resistance to the flow of steam and improves efficiency. * It is difficult to lubricate slide valves adequately in the presence of superheated steam. Murdoch's D slide valve The D slide valve, or more specifically Long D slide valve, is a form of slide valve, invented by William Murdoch and patented in 1799. It is named after the hollow central D-sectioned piston. This valve worked by "connecting the upper and lower valves so as to be worked by one rod or spindle, and in maki ...

Geared Steam Locomotives
A geared steam locomotive is a type of steam locomotive which uses gearing, usually reduction gearing, in the drivetrain, as opposed to the common directly driven design. This gearing is part of the machinery within the locomotive and should not be confused with the pinion that propels a rack locomotive along the rack between the rails. The geared steam locomotives that have been built have been for conventional track, relying on the adhesion between wheels and rail. Explanation and rationale The steam locomotive, as commonly employed, has its pistons directly attached to cranks on the driving wheels; thus, there is no gearing, one revolution of the driving wheels is equivalent to one revolution of the crank and thus two power strokes per piston (steam locomotives are almost universally double-acting, unlike the more familiar internal combustion engine). The maximum rotational speed is fairly fixed for a given engine technology. Given the lack of any variable-ratio transmiss ...

Rail transport (also known as train transport) is a means of transport that transfers passengers and goods on wheeled vehicles running on rails, which are incorporated in tracks. In contrast to road transport, where the vehicles run on a prepared flat surface, rail vehicles (rolling stock) are directionally guided by the tracks on which they run. Tracks usually consist of steel rails, installed on sleepers (ties) set in ballast, on which the rolling stock, usually fitted with metal wheels, moves. Other variations are also possible, such as "slab track", in which the rails are fastened to a concrete foundation resting on a prepared subsurface. Rolling stock in a rail transport system generally encounters lower frictional resistance than rubber-tyred road vehicles, so passenger and freight cars (carriages and wagons) can be coupled into longer trains. The operation is carried out by a railway company, providing transport between train stations or freight customer faciliti ...

''The'' () is a grammatical article in English, denoting persons or things that are already or about to be mentioned, under discussion, implied or otherwise presumed familiar to listeners, readers, or speakers. It is the definite article in English. ''The'' is the most frequently used word in the English language; studies and analyses of texts have found it to account for seven percent of all printed English-language words. It is derived from gendered articles in Old English which combined in Middle English and now has a single form used with nouns of any gender. The word can be used with both singular and plural nouns, and with a noun that starts with any letter. This is different from many other languages, which have different forms of the definite article for different genders or numbers. Pronunciation In most dialects, "the" is pronounced as (with the voiced dental fricative followed by a schwa) when followed by a consonant sound, and as (homophone of the archaic pron ...

Mineral, Washington
Mineral is an unincorporated community and census-designated place (CDP) in Lewis County, Washington, on State Route 7 near the Pierce/Lewis county line. Mineral originally began as a logging camp and mining town. Prospectors searching the area for gold instead found coal and arsenic. By the early 1920s, the mines closed, and with a devastating fire to the town's largest sawmill, Mineral began to turn to tourism as its main industry, primarily through recreational fishing on Mineral Lake. The Mineral Log Lodge, built in 1906, was listed to the National Register of Historic Places in 1975. History The town was founded no later than 1897 on the shore of Mineral Lake, adopting the name from the lake and the veins of ruby of arsenic in the region. The area would be referred to as Mineral City and Mineral Creek in its early days. The lake was once known as "Goldsboro Lake". Primarily a timber community, arsenic mines would open and the population peaked at 1,000 residents by the 19 ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Anaconda Copper
The Anaconda Copper Mining Company, known as the Amalgamated Copper Company between 1899 to 1915, was an American mining company headquartered in Butte, Montana. It was one of the largest trusts of the early 20th century and one of the largest mining companies in the world for much of the 20th century. Marcus Daly bought the original silver mine, named the Anaconda, in 1880. Daly partnered with George Hearst, James Ben Ali Haggin and Lloyd Tevis in 1881 to develop it, and the company expanded dramatically in 1882 with the discovery of huge copper deposits. In 1883, Daly began building a smelter and the town of Anaconda to process copper mined in Butte. In 1899, with Hearst and Tevis deceased, Haggin retired and Daly restructured the company, into the Amalgamated Copper Company bringing in H H Rogers and William Rockefeller. By 1910, Amalgamated had expanded its operations and bought the assets of all other copper companies operating in Butte. In 1922, Anaconda bought mining ope ...

Valve
A valve is a device or natural object that regulates, directs or controls the flow of a fluid (gases, liquids, fluidized solids, or slurries) by opening, closing, or partially obstructing various passageways. Valves are technically fittings, but are usually discussed as a separate category. In an open valve, fluid flows in a direction from higher pressure to lower pressure. The word is derived from the Latin ''valva'', the moving part of a door, in turn from ''volvere'', to turn, roll. The simplest, and very ancient, valve is simply a freely hinged flap which swings down to obstruct fluid (gas or liquid) flow in one direction, but is pushed up by the flow itself when the flow is moving in the opposite direction. This is called a check valve, as it prevents or "checks" the flow in one direction. Modern control valves may regulate pressure or flow downstream and operate on sophisticated automation systems. Valves have many uses, including controlling water for irrigation, ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Stephenson Valve Gear
The Stephenson valve gear or Stephenson link or shifting link is a simple design of valve gear that was widely used throughout the world for various kinds of steam engines. It is named after Robert Stephenson but was invented by his employees. Historical background During the 1830s, the most popular valve drive for steam locomotives was known as '' gab motion'' in the United Kingdom and'' V-hook motion'' in the United States. The gab motion incorporated two sets of eccentrics and rods for each cylinder; one eccentric was set to give forward and the other backwards motion to the engine and one or the other could accordingly engage with a pin driving the distribution valve by means of the gabs: - vee-shaped ends to the eccentric rods supposed to catch the rocker driving the valve rod whatever its position. It was a clumsy mechanism, difficult to operate, and only gave fixed valve events. In 1841, two employees of Robert Stephenson and Company, draughtsman William Howe and patte ...
