Willamette Iron And Steel Works
Willamette Iron Works (also known as Willamette Iron and Steel Company or WISCO) was a general foundry and machine business established in 1865 in Portland, Oregon, originally specializing in the manufacture of steamboat boilers and engines. In 1904, the company changed its name to Willamette Iron and Steel Works, under which name it operated continually until its close in 1990. The works was very busy during the World War I shipbuilding boom, building boilers for Northwest Steel and Albina Engine & Machine Works in Portland, G. M. Standifer Construction in Vancouver, Alameda Works Shipyard, Union Iron Works, Western Pipe and Steel, Schaw-Batcher and the Moore Dry Dock Company in San Francisco, Southwestern Shipbuilding Company, Southwestern Shipbuilding and the Long Beach Shipbuilding Company in Los Angeles, Skinner & Eddy, J.

Todd Dry Dock And Construction Company
The Seattle-Tacoma Shipbuilding Corporation (also operating as Todd Pacific) was an American corporation which built escort carriers, destroyers, cargo ships and auxiliaries for the United States Navy and merchant marine during World War II in two yards in Puget Sound, Washington. It was the largest producer of destroyers (45) on the West Coast and the largest producer of escort carriers of various classes (56) of any United States yard active during World War II. History The Todd Corporation, just having established itself in New York, acquired the Seattle Construction and Drydock Company (a.k.a. ''The Moran Brothers Shipyard'' of Klondike Gold Rush fame) in Seattle Harbor during World War I some time in 1916. The yard was acquired in 1918 by Skinner & Eddy, which had quickly risen to become a major force in Northwest Pacific shipbuilding. Todd moved his Seattle operation to nearby Harbor Island where a repair facility was constructed. In 1917 the company also set foot in ...

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-like locomotive designs. History Willamette Iron and Steel Works in Portland, Oregon, was well established in the Pacific Northwest, as a logging operations supplier, when they expanded into locomotive building. Their design of the Willamette locomotives, was focused on logging, incorporating all of the modern (in 1922) aspects of a Shay locomotive and the standard features most requested by western loggers; steel cabs, girder frame, cast trucks, air brakes, electric headlamps. The unique features of the locomotive were patented in 1923 (patent No. 1,464,696) by Albert Claypoole, an engineer with Willamette Iron and Steel Works. All Willamette locos were Standard gauge, 56½". A total of 33 were built in Portland Oregon, ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Locomotive
A locomotive is a rail transport, rail vehicle that provides the motive power for a train. Traditionally, locomotives pulled trains from the front. However, Push–pull train, push–pull operation has become common, and in the pursuit for longer and heavier freight trains, companies are increasingly using distributed power: single or multiple locomotives placed at the front and rear and at intermediate points throughout the train under the control of the leading locomotive. Etymology The word ''locomotive'' originates from the Latin language, Latin 'from a place', Ablative case, ablative of 'place', and the Medieval Latin 'causing motion', and is a shortened form of the term ''locomotive engine'', which was first used in 1814 to distinguish between self-propelled and stationary steam engines. Classifications Prior to locomotives, the motive force for railways had been generated by various lower-technology methods such as human power, horse power, Gravity railroad, g ...

Liberty Ship
Liberty ships were a ship class, class of cargo ship built in the United States during World War II under the Emergency Shipbuilding Program. Although British in concept, the design was adopted by the United States for its simple, low-cost construction. Mass-produced on an unprecedented scale, the Liberty ship came to symbolize U.S. wartime industrial output. The class was developed to meet British orders for transports to replace ships that had been lost. Eighteen American shipyards built 2,710 Liberty ships between 1941 and 1945 (an average of three ships every two days), easily the largest number of ships ever produced to a single design. The Liberty ship was effectively superseded by the Victory ship, a somewhat larger, materially faster, more modern-powered vessel of generally similar design. Over 500 were built between 1943 and 1945. Liberty ship production mirrored (albeit on a much larger scale) the manufacture of "Hog Islander" and similar standardized ship types duri ...

Triple Expansion
A steam engine is a heat engine that performs mechanical work using steam as its working fluid. The steam engine uses the force produced by steam pressure to push a piston back and forth inside a cylinder. This pushing force can be transformed by a connecting rod and crank into rotational force for work. The term "steam engine" is most commonly applied to reciprocating engines as just described, although some authorities have also referred to the steam turbine and devices such as Hero's aeolipile as "steam engines". The essential feature of steam engines is that they are external combustion engines, where the working fluid is separated from the combustion products. The ideal thermodynamic cycle used to analyze this process is called the Rankine cycle. In general usage, the term ''steam engine'' can refer to either complete steam plants (including boilers etc.), such as railway steam locomotives and portable engines, or may refer to the piston or turbine machinery alone, ...

Kaiser Shipyards
The Kaiser Shipyards were seven major shipbuilding yards located on the West Coast of the United States, United States west coast during World War II. Kaiser ranked 20th among U.S. corporations in the value of wartime production contracts. The shipyards were owned by the Kaiser Shipbuilding Company, a creation of American industrialist Henry J. Kaiser (1882–1967), who established the shipbuilding company around 1939 in order to help meet the construction goals set by the United States Maritime Commission for merchant shipping. Four of the Kaiser Shipyards were located in Richmond, California, and were called the Richmond Shipyards. Three other shipyards were located in the Pacific Northwest along the Columbia River, Columbia and Willamette River, Willamette rivers: the Oregon Shipbuilding Corporation and the Swan Island Shipyard in Portland, Oregon, and the Vancouver Shipyard in Vancouver, Washington. Henry Kaiser was known for developing new methods of shipbuilding, which a ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
The Georgian Press
''The'' is a grammatical article in English, denoting nouns 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 pronoun ''thee' ...

Henry J
The Henry J is an American automobile built by the Kaiser-Frazer Corporation and named after its chairman, Henry J. Kaiser. Mass production, Production of six-cylinder models began in their Willow Run factory in Michigan in July 1950, and four-cylinder production started shortly after Labor Day, 1950. The official public introduction was on September 28, 1950, and the car was marketed until 1954. Development The Henry J was the idea of Henry J. Kaiser, who sought to increase sales of his Kaiser automotive line by adding a car that could be built inexpensively and thus affordable for the average American in the same vein that Henry Ford produced the Model T. The goal was to attract "less affluent buyers who could only afford a used car", and the attempt became a pioneering American compact car. The Kaiser-Frazer Corporation received a federal government loan in 1949 to finance the project. This monetary support specified various particulars of the vehicle. Kaiser-Frazer would ...

Lighter (barge)
A lighter is a type of flat-bottomed barge used to transfer goods and passengers to and from Mooring (watercraft), moored ships. Lighters were traditionally unpowered and were moved and steered using long oars called "sweeps" and the motive power of water currents. They were operated by skilled workers called lightermen and were a characteristic sight in London Docklands, London's docks until about the 1960s, when technological changes made this form of lightering largely redundant. Unpowered lighters continue to be moved by powered tugs, however, and lighters may also now themselves be powered. The term is also used in the Lighter Aboard Ship (LASH) system. The name itself is of uncertain origin, but is believed to possibly derive from an old Dutch language, Dutch or German language, German word, ''lichten'' (to lighten or unload). In Dutch and German, the words ''lichter'' or ''Leichter'' are still used for smaller ships that take over goods from larger ships. Lighters, albeit ...

Submarine Chaser
A submarine chaser or subchaser is a type of small naval vessel that is specifically intended for anti-submarine warfare. They encompass designs that are now largely obsolete, but which played an important role in the wars of the first half of the 20th century. Many of the American submarine chasers used in World War I found their way to Allies (World War II), Allied nations by way of Lend-Lease in World War II. Submarine chaser variants U.S. Navy submarine chasers were designed specifically to destroy German Empire, German submarines in World War I, and Empire of Japan, Japanese and Nazi Germany, German submarines in World War II. The small SC-1-class submarine chasers of the design used in World War I carried the hull designator SC (for Submarine Chaser). Their main weapon was the depth charge. They also carried machine guns and anti-aircraft guns. The similar-sized SC-497-class submarine chaser, SC-497-class was built for World War II. Also in World War II, larger PC-461-cla ...

Patrol Craft
A patrol boat (also referred to as a patrol craft, patrol ship, or patrol vessel) is a relatively small naval vessel generally designed for coastal defence, border security, or law enforcement. There are many designs for patrol boats, and they generally range in size. They may be operated by a nation's navy, coast guard, police, or customs, and may be intended for marine ("blue water"), estuarine (" green water"), or river (" brown water") environments. Per their name, patrol boats are primarily used to patrol a country's exclusive economic zone (EEZ), but they may also be used in other roles, such as anti-smuggling, anti-piracy, fishery patrols, immigration law enforcement, or search and rescue. Depending on the size, organization, and capabilities of a nation's armed forces, the importance of patrol boats may range from minor support vessels that are part of a coast guard, to flagships that make up a majority of a navy's fleet. Their small size and relatively low cost make t ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
