Marathon-class Cruiser
The ''Marathon''-class cruiser was a class of second class cruiser of the Royal Navy ordered under the naval programme of 1887. The class was a smaller version of the . Three of the ships, ''Melpomene'', ''Magicienne'' and ''Marathon'', were built for foreign (tropical) service, with a sheath of wood and copper - this added weight and made them slightly slower. Ships Boiler trials By 1901, the Royal Navy had ordered eight Dürr boilers from Germany, to be installed as a trial on board as a substitute for the Belleville boiler There have been a vast number of designs of steam boiler, particularly towards the end of the 19th century when the technology was evolving rapidly.

Machine Gun
A machine gun is a fully automatic, rifled autoloading firearm designed for sustained direct fire with rifle cartridges. Other automatic firearms such as automatic shotguns and automatic rifles (including assault rifles and battle rifles) are typically designed more for firing short bursts rather than continuous firepower, and are not considered true machine guns. As a class of military kinetic projectile weapon, machine guns are designed to be mainly used as infantry support weapons and generally used when attached to a bipod or tripod, a fixed mount or a heavy weapons platform for stability against recoils. Many machine guns also use belt feeding and open bolt operation, features not normally found on other infantry firearms. Machine guns can be further categorized as light machine guns, medium machine guns, heavy machine guns, general purpose machine guns and squad automatic weapons. Similar automatic firearms of caliber or more are classified as autocannons, rat ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Cruiser Classes
A cruiser is a type of warship. Modern cruisers are generally the largest ships in a fleet after aircraft carriers and amphibious assault ships, and can usually perform several roles. The term "cruiser", which has been in use for several hundred years, has changed its meaning over time. During the Age of Sail, the term ''cruising'' referred to certain kinds of missions—independent scouting, commerce protection, or raiding—fulfilled by frigates or sloops-of-war, which functioned as the ''cruising warships'' of a fleet. In the middle of the 19th century, ''cruiser'' came to be a classification of the ships intended for cruising distant waters, for commerce raiding, and for scouting for the battle fleet. Cruisers came in a wide variety of sizes, from the medium-sized protected cruiser to large armored cruisers that were nearly as big (although not as powerful or as well-armored) as a pre-dreadnought battleship. With the advent of the dreadnought battleship before World W ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
William Allan (UK Politician)
Sir William Allan (29 November 1837 – 28 December 1903) was a Scottish Liberal Party (UK), Liberal Party politician and engineer. He was Member of Parliament (United Kingdom), Member of Parliament for Gateshead (UK Parliament constituency), Gateshead from 1893 until his death in 1903. Allan was born in Dundee, the son of engineer James Allan. His father suffered financial failure, causing Allan to begin work as an apprentice at age 10. He emigrated to the United States, working for several years in Paterson, New Jersey before returning to Glasgow. He began his professional career was as a steamship engineer in the early years of construction of these vessels and his business was the Scotia engineering works in Sunderland, England. He was also involved with a sea line, the Albyn Line. His early life included crew experience on steamships which were at one stage Arms trafficking, gun-running to America during the American Civil War, and he wrote of a number of dangerous e ...

Belleville Boiler
There have been a vast number of designs of steam boiler, particularly towards the end of the 19th century when the technology was evolving rapidly. A great many of these took the names of their originators or primary manufacturers, rather than a more descriptive name. Some large manufacturers also made boilers of several types. Accordingly, it is difficult to identify their technical aspects from merely their name. This list presents these known, notable names and a brief description of their main characteristics. See also * Glossary of boiler terminology Boilers for generating steam or hot water have been designed in countless shapes, sizes and configurations. An extensive terminology has evolved to describe their common features. This glossary provides definitions for these terms. Terms which re ...

Dürr Boiler
A Field-tube boiler (also known as a bayonet tube) is a form of water-tube boiler where the water tubes are single-ended. The tubes are closed at one end, and they contain a concentric inner tube. Flow is thus separated into the colder inner flow down the tube and the heated flow upwards through the outer sleeve. As Field tubes are thus dependent on thermo-syphon flow ''within'' the tube, they must thus always have some vertical height to encourage the flow. In most designs they are mounted near-vertically, to encourage this. They are named after Edward Field, their inventor, and were originally developed for steam fire-engines where speed of raising steam was important. More recently, Field-tube boilers have been most widely used by French manufacturers, either for small vertical boilers, or as a marine boiler. The use of this type of Field tube has also been researched for the transfer of heat from nuclear reactors, vacuum condensers and heat exchangers. The thimble-tube boi ...

Royal Navy
The Royal Navy (RN) is the United Kingdom's naval warfare force. Although warships were used by English and Scottish kings from the early medieval period, the first major maritime engagements were fought in the Hundred Years' War against France. The modern Royal Navy traces its origins to the early 16th century; the oldest of the UK's armed services, it is consequently known as the Senior Service. From the middle decades of the 17th century, and through the 18th century, the Royal Navy vied with the Dutch Navy and later with the French Navy for maritime supremacy. From the mid 18th century, it was the world's most powerful navy until the Second World War. The Royal Navy played a key part in establishing and defending the British Empire, and four Imperial fortress colonies and a string of imperial bases and coaling stations secured the Royal Navy's ability to assert naval superiority globally. Owing to this historical prominence, it is common, even among non-Britons, to ref ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Torpedo Tube
A torpedo tube is a cylindrical device for launching torpedoes. There are two main types of torpedo tube: underwater tubes fitted to submarines and some surface ships, and deck-mounted units (also referred to as torpedo launchers) installed aboard surface vessels. Deck-mounted torpedo launchers are usually designed for a specific type of torpedo, while submarine torpedo tubes are general-purpose launchers, and are often also capable of deploying naval mine, mines and cruise missiles. Most modern launchers are standardized on a diameter for light torpedoes (deck mounted aboard ship) or a diameter for heavy torpedoes (underwater tubes), although other sizes of torpedo tube have been used: see Torpedo#Classes and diameters, Torpedo classes and diameters. Submarine torpedo tube A submarine torpedo tube is a more complex mechanism than a torpedo tube on a surface ship, because the tube has to accomplish the function of moving the torpedo from the normal atmospheric pressure within t ...

QF 3-pounder Hotchkiss
The QF 3-pounder Hotchkiss or in French use Canon Hotchkiss à tir rapide de 47 mm were a family of long-lived light naval guns introduced in 1886 to defend against new, small and fast vessels such as torpedo boats and later submarines. There were many variants produced, often under license which ranged in length from 32 to 50 calibers but 40 caliber was the most common version. They were widely used by the navies of a number of nations and often used by both sides in a conflict. They were also used ashore as coastal defense guns and later as an anti-aircraft gun, whether on improvised or specialized HA/LA mounts. Operational history French service The French Navy used two versions of the Hotchkiss 3-pounder: the short-barreled M1885 and the long-barreled M1902, which had a larger muzzle velocity than its predecessor. The French L/40 M1885 and the British QF 3-pounder were largely the same gun. Like the British who paired their 3-pounders with the larger QF 6-poun ...

Chromolithograph
Chromolithography is a method for making multi-colour printmaking, prints. This type of colour printing stemmed from the process of lithography, and includes all types of lithography that are printed in colour. When chromolithography is used to reproduce photographs, the term photochrome is frequently used. Lithographers sought to find a way to print on flat surfaces with the use of chemicals instead of raised Relief print, relief or recessed Intaglio (printmaking), intaglio techniques."Chromolithography and the Posters of World War I." ''The War on the Walls''. Temple University. 11 April 2007. . A chromolithograph is also known as an oleograph. Chromolithography became the most successful of several methods of color printing, colour printing developed by the 19th century; other methods were developed by printers such as Jacob Christoph Le Blon, George Baxter (printer), George Baxter and Edmund Evans, and mostly relied on using several woodcut, woodblocks with the colours.
