GWR 4100 Class
The GWR 4100 Class was a class of steam locomotives in the Great Western Railway (GWR) of the United Kingdom. The Badminton class express passenger 4-4-0 steam locomotives were introduced in 1897 as a development from the earlier GWR 3252 Class, Duke class. The name Badminton was chosen after the Duke of Beaufort's Badminton House, Badminton estate, through which the GWR was building South Wales Main Line, a new line to South Wales at the time. Further modifications to the design resulted in the Atbara Class entering service in 1900, the names for these locomotives generally being taken from contemporary military engagements or senior army commanders. Later engines were named after cities of the British Empire. The final batch of locomotives were named after varieties of garden plant and in consequence were known as the Flower Class. These three types were later standardised and treated as a single class, so are listed together here. Four other prototype 4-4-0s, originally bu ...

William Dean (engineer)
William Dean (8 January 1840 – 24 September 1905) was an English railway engineer. He was the second son of Henry Dean, who was the manager of the Hawes Soap Factory in New Cross, London. William was educated at the Haberdashers' Company School. He became the Chief Locomotive Engineer for the Great Western Railway from 1877, when he succeeded Joseph Armstrong (engineer), Joseph Armstrong. He retired from the post in 1902 and was replaced by George Jackson Churchward. He designed famous steam locomotive classes such as the GWR 3252 Class, Duke Class, the GWR 3300 Class, Bulldog Class and the long-lived GWR 2301 Class, 2301 Class. Apprenticeship He was apprenticed at the age of fifteen to Joseph Armstrong at the Great Western Railway's Wolverhampton Wolverhampton railway works, Stafford Road Works.

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 ...

Earl Cawdor
Earl Cawdor, of Castlemartin in the County of Pembroke, is a title in the Peerage of the United Kingdom. It was created in 1827 for John Campbell, 2nd Baron Cawdor. This branch of Clan Campbell descends from Sir John Campbell (died 1546), third son of Archibald Campbell, 2nd Earl of Argyll (whose eldest son Colin was the ancestor of the Dukes of Argyll; see the latter title for earlier history of the family). His descendant Pryse Campbell (d. 1768) represented Nairnshire in the House of Commons. His son John Campbell was Member of Parliament for Nairnshire and Cardigan. In 1796 he was raised to the Peerage of Great Britain as Baron Cawdor, of Castlemartin in the County of Pembroke. He was succeeded by his eldest son, the second Baron. He represented Carmarthenshire in Parliament and served as Lord Lieutenant of Carmarthenshire. In 1827 he was created Viscount Emlyn, of Emlyn in the County of Carmarthen, and Earl Cawdor, of Castlemartin in the County of Pembroke. These ...

Cambria
Cambria is a name for Wales, being the Latinised form of the Welsh name for the country, . The term was not in use during the Roman period (when Wales had not come into existence as a distinct entity). It emerged later, in the medieval period, after the Anglo-Saxon settlement of much of Britain led to a territorial distinction between the new Anglo-Saxon kingdoms (which would become England and Southern Scotland) and the remaining Celtic British kingdoms (which would become Wales and, before their absorption into England, Cornwall to the south and Strathclyde or Hen Ogledd to the north). Latin being the primary language of scholarship in Western Christendom, writers needed a term to refer to the Celtic British territory and coined based on the Welsh name for it. Etymology The Welsh word (Wales), along with (Welsh people), was falsely supposed by 17th-century Celticists to be connected to the Biblical Gomer, or to the Cimbri or the Cimmerians of antiquity. In reality, it is d ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Frederick Ponsonby, 6th Earl Of Bessborough
Frederick George Brabazon Ponsonby, 6th Earl of Bessborough (11 September 1815 – 11 March 1895), was an Anglo-Irish peer who played first-class cricket 1834–56 for Surrey, Cambridge Town Club (''aka'' Cambridgeshire), Cambridge University (CUCC) and Marylebone Cricket Club (MCC). Background and education Ponsonby was born in Marylebone, the third son of John Ponsonby, 4th Earl of Bessborough, and his wife Lady Maria Fane. He was educated at Harrow and Trinity College, Cambridge. In 1837 he was admitted to Lincoln's Inn, and was called to the Bar in 1840. He inherited the earldom on 28 January 1880 when his elder brother died without a male heir. Cricket Throughout his cricket career, Bessborough was known as the Hon. Frederic Ponsonby. He played at both Harrow and Cambridge University, batting right-handed. He was an active player until about 1845, after which, due to an arm injury, he could only play sporadically. Ponsonby was a founder of Surrey County Cricket Club and wa ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Blenheim Palace
Blenheim Palace (pronounced ) is a country house in Woodstock, Oxfordshire, England. It is the seat of the Dukes of Marlborough and the only non-royal, non- episcopal country house in England to hold the title of palace. The palace, one of England's largest houses, was built between 1705 and 1722, and designated a UNESCO World Heritage Site in 1987. The palace is named after the 1704 Battle of Blenheim. It was originally intended to be a reward to John Churchill, 1st Duke of Marlborough for his military triumphs against the French and Bavarians in the War of the Spanish Succession, culminating in the Battle of Blenheim. The land was given as a gift, and construction began in 1705, with some financial support from Queen Anne. The project soon became the subject of political infighting, with the Crown cancelling further financial support in 1712, Marlborough's three-year voluntary exile to the Continent, the fall from influence of his duchess, and lasting damage to the ...

William Barrington, 6th Viscount Barrington
William Keppel Barrington, 6th Viscount Barrington (6 October 1793 – 9 February 1867), styled The Honourable from 1814 until 1829, was a British businessman and politician. Early life Born in London on 6 October 1793, Barrington was the eldest son of fifteen children born to the Reverend George Barrington, 5th Viscount Barrington, by his wife Elizabeth, second daughter of Robert Adair and Lady Caroline Keppel (the second daughter of Willem van Keppel, 2nd Earl of Albemarle), a descendant of Charles Lennox, 1st Duke of Richmond. Like his father, he was educated at Westminster School and Christ Church, Oxford, where he graduated with a Bachelor of Arts in 1814. Career Barrington succeeded in the viscountcy on the death of his father in 1829. However, as this was a title in the Peerage of Ireland, it did not entitle him to a seat in the House of Lords. In 1837 he was instead elected to the House of Commons as one of three representatives for Berkshire, a seat he held until 1857. ...

Steam Locomotive
A steam locomotive is a locomotive that provides the force to move itself and other vehicles by means of the expansion of steam. It is fuelled by burning combustible material (usually coal, oil or, rarely, wood) to heat water in the locomotive's boiler to the point where it becomes gaseous and its volume increases 1,700 times. Functionally, it is a steam engine on wheels. In most locomotives, the steam is admitted alternately to each end of its cylinders, in which pistons are mechanically connected to the locomotive's main wheels. Fuel and water supplies are usually carried with the locomotive, either on the locomotive itself or in a tender coupled to it. Variations in this general design include electrically-powered boilers, turbines in place of pistons, and using steam generated externally. Steam locomotives were first developed in the United Kingdom during the early 19th century and used for railway transport until the middle of the 20th century. Richard Trevithick ...

Connecting Rod
A connecting rod, also called a 'con rod', is the part of a piston engine which connects the piston to the crankshaft. Together with the crank, the connecting rod converts the reciprocating motion of the piston into the rotation of the crankshaft. The connecting rod is required to transmit the compressive and tensile forces from the piston. In its most common form, in an internal combustion engine, it allows pivoting on the piston end and rotation on the shaft end. The predecessor to the connecting rod is a mechanic linkage used by water mills to convert rotating motion of the water wheel into reciprocating motion. The most common usage of connecting rods is in internal combustion engines or on steam engines. __TOC__ Origins The predecessor to the connecting length is the mechanical linkage used by Roman-era watermills. The earliest known example of this linkage has been found at the late 3rd century Hierapolis sawmill in Roman Asia (modern Turkey) and the 6th century ...

Coupling Rod
A coupling rod or side rod connects the driving wheels of a locomotive. Steam locomotives in particular usually have them, but some diesel and electric locomotives, especially older ones and shunters, also have them. The coupling rods transfer the power of drive to all wheels. Development Locomotion No. 1 was the first locomotive to employ coupling rods rather than chains. In the 1930s reliable roller bearing coupling rods were developed. Allowance for vertical motion In general, all railroad vehicles have spring suspension; without springs, irregularities in the track could lift wheels off the rail and cause impact damage to both rails and vehicles. Driving wheels are typically mounted so that they have around 1 inch (2.5 cm) of vertical motion. When there are only 2 coupled axles, this range of motion places only slight stress on the crank pins. With more axles, however, provision must be made to allow each axle to move vertically independently of the others without be ...

Crankpin
A crankpin or crank pin, also known as a rod bearing journal, is a mechanical device in an engine which connects the crankshaft to the connecting rod for each cylinder. It has a cylindrical surface, to allow the crankpin to rotate relative to the "big end" of the connecting rod. The most common configuration is for a crankpin to serve one cylinder. However, many V engines have each crankpin shared by each pair of cylinders. Design The crankpin connects to the larger end of the connecting rod for each cylinder. This end of the connecting rod is called the "big end", as opposed to the "small end" or "little end" (which connects to the wrist/gudgeon pin in the piston). The bearing which allows the crankpin to rotate around its shaft is called the "rod bearing". In automotive engines, the most common type of rod bearing is the plain bearing, however Bushing (bearing), bushings or roller bearings are also used in some engines. Configurations In a single-cylinder engine, strai ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Piston Valve (steam Engine)
Piston valves are one form of valve used to control the flow of steam within a steam engine or locomotive. They control the admission of steam into the cylinders and its subsequent exhausting, enabling a locomotive to move under its own power. The valve consists of two piston heads on a common spindle moving inside a steam chest, which is essentially a mini-cylinder located either above or below the main cylinders of the locomotive. Overview In the 19th century, 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: * It is difficult to lubricate slide valves adequately in the presence of superheated steam * With piston valves, the steam passages can be made shorter. This, particularly following the work of André Chapelon, reduces resistance to the flow of steam and improves eff ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
