HMS Favorite (1864)
HMS ''Favorite'' was one of the three wooden warships of moderate dimension (the others being and ) selected by Sir Edward Reed for conversion to broadside ironclads in response to the increased tempo of French warship building. Background and design ''Favorite'' was named after a French prize-of-war, and hence her name is spelled in the French way. She was laid down as a corvette of 22 guns of the ''Jason'' class, and was selected for conversion after being two years on the builder's slipway. The hull form was already complete, so modifications were restricted to the installation of a rounded stern and a straight stem in place of the traditional overhanging stern and knee bow. She carried her armour in a box battery amidships, and the guns carried therein, four on each side, were the heaviest naval cannon of the day. A degree of axial (fore and aft) fire was enabled through an arrangement in which part of the battery wall could be recessed, and one of the guns could be traver ...

Funnel (ship)
A funnel is the smokestack or chimney on a ship used to expel boiler steam and smoke or engine exhaust. They are also commonly referred to as stacks. Purpose The primary purpose of a ship's funnel(s) is to lift the exhaust gases clear of the deck, in order not to foul the ship's structure or decks, and to avoid impairing the ability of the crew to carry out their duties. In steam ships the funnels also served to help induce a convection draught through the boilers. Design Since the introduction of steam-power to ships in the 19th century, the funnel has been a distinctive feature of the silhouette of a vessel, and used for recognition purposes. Funnel area The required funnel cross-sectional area is determined by the volume of exhaust gases produced by the propulsion plant. Often this area is too great for a single funnel. Early steam vessels needed multiple funnels ( had 5 when launched), but as efficiency increased new machinery needed fewer funnels. Merchant ships ...

Humphreys & Tennant
Humphrys, Tennant and Dykes (later named Humphrys, Tennant and Co.) was a British engineering company based in Deptford, London, England. History The company was founded in 1852 by Edward Humphrys, formerly chief engineer of Woolwich Dockyard, where Dykes was also employed in the steam factory. In 1882 the name was changed to Humphrys, Tennant and Co. of Deptford Pier, London. It specialised in building large marine steam engines and boilers, including those for the Navy's fast cruisers and iron-clad battleships. The 50 years of production started in the early days of screw-propellers (as opposed to paddle wheels) and spanned great changes in the available pressure from boilers and the resulting power of the engines, as well as in the construction and form of ships. Their main competitors were Maudslay, Sons and Field and John Penn and Sons. The works at Deptford Pier was closed in 1907. Early installations One of the early records of a Humphrys, Tennant and Dykes steam engine w ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Horsepower
Horsepower (hp) is a unit of measurement of power, or the rate at which work is done, usually in reference to the output of engines or motors. There are many different standards and types of horsepower. Two common definitions used today are the mechanical horsepower (or imperial horsepower), which is about 745.7 watts, and the metric horsepower, which is approximately 735.5 watts. The term was adopted in the late 18th century by Scottish engineer James Watt to compare the output of steam engines with the power of draft horses. It was later expanded to include the output power of other types of piston engines, as well as turbines, electric motors and other machinery. The definition of the unit varied among geographical regions. Most countries now use the SI unit watt for measurement of power. With the implementation of the EU Directive 80/181/EEC on 1 January 2010, the use of horsepower in the EU is permitted only as a supplementary unit. History The development of the ...

Somerset Cannon
The Somerset cannon was a British cannon designed within the Admiralty and manufactured by Armstrong's. Its genesis was the unexpected failure of the Armstrong breech-loading rifles recently developed and installed on Royal Navy ships. The ''Somerset'' was a 6.5 ton 9.2-inch calibre smoothbore muzzle-loader, firing a 100-pound shot. With a charge of 33 pounds of gunpowder, a steel shot could penetrate 5.5 inches of armour at 800 yards. Providing a mounting which could reliably be worked at sea proved difficult for a piece of this size. Traditional truck carriages were inadequate; historical research revealed that a carriage which was suitable had been suggested by Captain Sir Thomas Hardy (Nelson Nelson may refer to: Arts and entertainment * ''Nelson'' (1918 film), a historical film directed by Maurice Elvey * ''Nelson'' (1926 film), a historical film directed by Walter Summers * ''Nelson'' (opera), an opera by Lennox Berkeley to a lib ...'s Flag Captain) many years ...

RML 7 Inch Gun
The RML 7-inch guns were various designs of medium-sized rifled muzzle-loading guns used to arm small to medium-sized British warships in the late 19th century, and some were used ashore for coast defence. Design and history These guns were the first to incorporate the new "Woolwich" rifling system, a modification of the French system, of from 3 – 9 broad shallow grooves after Britain abandoned the Armstrong "shunt" rifling system in May 1865 : "...M.L. 7-inch guns in course of manufacture were rifled on this principle, upon which all of our heavy pieces since have been rifled. The 7-inch referred to, and introduced into the service in 1865, were the first of the so-called Woolwich guns, which then meant "''wrought iron M.L. guns built up on Sir W. Armstrong's principle, improved upon by hooking the coils over one another, and having solid ended steel barrels, rifled on the system shown above, for studded projectiles''". All versions were constructed of a steel A tube surroun ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
68 Pounder Gun
The 68-pounder cannon was an artillery piece designed and used by the British Armed Forces in the mid-19th century. The cannon was a smoothbore muzzle-loading gun manufactured in several weights, the most common being , and fired projectiles of . Colonel William Dundas designed the 112 cwt version in 1841 and it was cast the following year. The most common variant, weighing 95 cwt, dates from 1846. It entered service with the Royal Artillery and the Royal Navy and saw active service with both arms during the Crimean War. Over 2,000 were made and it gained a reputation as the finest smoothbore cannon ever made. The gun was produced at a time when new rifled and breech loading guns were beginning to make their mark on artillery. At first the 68-pounder's reliability and power meant that it was retained even on new warships such as HMS ''Warrior'', but eventually new rifled muzzle loaders made all smoothbore muzzle-loading guns obsolete. However, the large surplus stocks ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Edward James Reed
Sir Edward James Reed, KCB, FRS (20 September 1830 – 30 November 1906) was a British naval architect, author, politician, and railroad magnate. He was the Chief Constructor of the Royal Navy from 1863 until 1870. He was a Liberal politician who sat in the House of Commons from 1874 to 1906. Early life Edward Reed was born in Sheerness, Kent and was the son of John and Elizabeth Reed. He was a naval apprentice at Sheerness and subsequently entered the School of Mathematics and Naval Construction at Portsmouth. In 1851 he married Rosetta, the sister of Nathaniel Barnaby. Barnaby was at that time a fellow student; he would subsequently succeed Reed as Chief Constructor. In 1852 he entered employment at Sheerness Dockyard, but resigned after a disagreement with the management. He then worked in journalism, including editing the ''Mechanics' Magazine''. In 1860, Reed was appointed secretary of the newly formed Institute of Naval Architects. Naval architect In 1863, at the ear ...

Broadside Ironclad
An ironclad is a steam engine, steam-propelled warship protected by Wrought iron, iron or steel iron armor, armor plates, constructed from 1859 to the early 1890s. The ironclad was developed as a result of the vulnerability of wooden warships to explosive or incendiary shell (projectile), shells. The first ironclad battleship, , was launched by the French Navy in November 1859 - narrowly pre-empting the British Royal Navy. They were first used in warfare in 1862 during the American Civil War, when ironclads operated against wooden ships and, in a historic confrontation, against each other at the Battle of Hampton Roads in Virginia. Their performance demonstrated that the ironclad had replaced the unarmored ship of the line as the most powerful warship afloat. City-class ironclad, Ironclad gunboats became very successful in the American Civil War. Ironclads were designed for several uses, including as high seas battleships, long-range cruisers, and Littoral (military), coast ...

Sheerness
Sheerness () is a town and civil parish beside the mouth of the River Medway on the north-west corner of the Isle of Sheppey in north Kent, England. With a population of 11,938, it is the second largest town on the island after the nearby town of Minster which has a population of 21,319. Sheerness began as a fort built in the 16th century to protect the River Medway from naval invasion. In 1665 plans were first laid by the Navy Board for Sheerness Dockyard, a facility where warships might be provisioned and repaired. The site was favoured by Samuel Pepys, then Clerk of the Acts of the navy, for shipbuilding over Chatham inland. After the raid on the Medway in 1667, the older fortification was strengthened; in 1669 a Royal Navy dockyard was established in the town, where warships were stocked and repaired until its closure in 1960. Beginning with the construction of a pier and a promenade in the 19th century, Sheerness acquired the added attractions of a seaside resort. ...
