Return Connecting Rod Engine
A return connecting rod, return piston rod or (in marine parlance) double piston rod engine or back-acting engine is a particular layout for a steam engine. The key attribute of this layout is that the piston rod emerges from the cylinder to the crosshead, but the connecting rod then reverses direction and goes ''backwards'' to the crankshaft. This layout is compact, but has mechanical disadvantages. Return connecting rod engines were thus rarely used, except in some mid-19th century marine applications where they had certain advantages. The return connecting rod layout has two possible forms: * The cylinder is between the crosshead and the crankshaft. This requires long connecting rods. To avoid unbalanced forces on the crosshead, these rods are usually paired and run either side of the cylinder. * The crankshaft is between the crosshead and cylinder. This requires a paired piston rod or yoke, so as to pass around the crankshaft. Both horizontal and vertical arrangements have us ...

James Watt
James Watt (; 30 January 1736 (19 January 1736 OS) – 25 August 1819) was a Scottish inventor, mechanical engineer, and chemist who improved on Thomas Newcomen's 1712 Newcomen steam engine with his Watt steam engine in 1776, which was fundamental to the changes brought by the Industrial Revolution in both his native Great Britain and the rest of the world. While working as an instrument maker at the University of Glasgow, Watt became interested in the technology of steam engines. At the time engineers such as John Smeaton were aware of the inefficiencies of Newcomen's engine and aimed to improve it. Watt's insight was to realise that contemporary engine designs wasted a great deal of energy by repeatedly cooling and reheating the cylinder. Watt introduced a design enhancement, the separate condenser, which avoided this waste of energy and radically improved the power, efficiency, and cost-effectiveness of steam engines. Eventually, he adapted his engine to produce rot ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Locomotion No 1
''Locomotion'' No. 1 (originally named ''Active'') is an early steam locomotive that was built in 1825 by the pioneering railway engineers George Stephenson, George and Robert Stephenson at their manufacturing firm, Robert Stephenson and Company. It became the first steam locomotive to haul a passenger-carrying train on a public railway, the Stockton and Darlington Railway (S&DR). ''Locomotion'' was ordered by the Stockton and Darlington Railway Company in September 1824; its design benefitted from George Stephenson's experience building his series of Killingworth locomotives. It is believed that ''Locomotion No. 1'' was the first locomotive to make use of coupling rods to link together its driving wheels, reducing the chance of the wheels slipping on the iron rails. However, the Shell boiler#Centre-flue boilers, centre-flue boiler proved to be a weakness, providing a poorer heating surface than later Fire-tube boiler, multi-flue boilers. In September 1825, ''Locomotion'' ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Blücher (locomotive)
George Stephenson built a number of experimental steam locomotives to work in the Killingworth Colliery between 1814 and 1826. Background George Stephenson was appointed as engine-wright at Killingworth Colliery in 1812 and immediately improved the haulage of the coal from the mine using fixed engines. But he had taken an interest in Blenkinsop's engines in Leeds and Blackett's experiments at Wylam colliery, where he had been born. By 1814 he persuaded the lessees of the colliery to fund a "travelling engine" which first ran on 25 July. By experiment he confirmed Blackett's observation that the friction of the wheels was sufficient on an iron railway without cogs but still used a cogwheel system in transmitting power to the wheels. ''Blücher'' ''Blücher'' (often spelled ''Blutcher'') was built by George Stephenson in 1814; the first of a series of locomotives that he designed in the period 1814–16 which established his reputation as an engine designer and laid the foun ...

George Stephenson
George Stephenson (9 June 1781 – 12 August 1848) was an English civil engineer and Mechanical engineering, mechanical engineer during the Industrial Revolution. Renowned as the "Father of Railways", Stephenson was considered by the Victorian era, Victorians as a great example of diligent application and thirst for improvement. His chosen Track gauge#The Stockton and Darlington Railway, rail gauge, sometimes called "Stephenson gauge", was the basis for the standard gauge used by most of the world's railways. Pioneered by Stephenson, rail transport was one of the most important technological inventions of the 19th century and a key component of the Industrial Revolution. Built by George and his son Robert Stephenson, Robert's company Robert Stephenson and Company, the Locomotion No. 1, ''Locomotion'' No. 1 was the first steam locomotive to carry passengers on a public rail line, the Stockton and Darlington Railway in 1825. George also built the first public inter-city railway ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Salamanca (locomotive)
'' Salamanca'' was the first commercially successful steam locomotive, built in 1812 by Matthew Murray of Holbeck, for the edge-railed Middleton Railway between Middleton and Leeds, England and it predated Stephenson's Rocket by 17 years. It was the first to have two cylinders. It was named after the Duke of Wellington's victory at the Battle of Salamanca which was fought that same year. ''Salamanca'' was also the first rack and pinion locomotive, using John Blenkinsop's patented design for rack propulsion. A single rack ran outside the narrow gauge tracks and was engaged by a large cog wheel on the left side of the locomotive. The cog wheel was driven by twin cylinders embedded into the top of the centre-flue boiler. The class was described as having two 8"×20" cylinders, driving the wheels through cranks. The piston crossheads slid in guides, rather than being controlled by a parallel motion linkage like the majority of early locomotives. The engines saw up to twen ...

Matthew Murray
Matthew Murray (1765 – 20 February 1826) was an English steam engine and machine tool manufacturer, who designed and built the first commercially viable steam locomotive, the twin-cylinder ''Salamanca'' in 1812. He was an innovative designer in many fields, including steam engines, machine tools and machinery for the textile industry. Early years Little is known about Matthew Murray's early years. He was born in Newcastle upon Tyne in 1765. He left school at fourteen and was apprenticed to be either a blacksmith or a whitesmith. In 1785, when he concluded his apprenticeship, he married Mary Thompson (1764–1836) of Whickham, County Durham. The following year he moved to Stockton and began work as a journeyman mechanic at the flax mill of John Kendrew in Darlington, where the mechanical spinning of flax had been invented.. Murray and his wife, Mary, had three daughters and a son, also called Matthew.. Leeds In 1789, due to a lack of trade in the Darlington flax mil ...

Forging
Forging is a manufacturing process involving the shaping of metal using localized compression (physics), compressive forces. The blows are delivered with a hammer (often a power hammer) or a die (manufacturing), die. Forging is often classified according to the temperature at which it is performed: cold forging (a type of cold working), warm forging, or hot forging (a type of hot working). For the latter two, the metal is heated, usually in a forge. Forged parts can range in weight from less than a kilogram to hundreds of metric tons.Degarmo, p. 389 Forging has been done by metalsmith, smiths for millennia; the traditional products were kitchenware, household hardware, hardware, hand tools, edged weapons, cymbals, and jewellery. Since the Industrial Revolution, forged parts are widely used in mechanism (engineering), mechanisms and machines wherever a component requires high strength of materials, strength; such forgings usually require further processing (such as machining) ...

Richard Trevithick
Richard Trevithick (13 April 1771 – 22 April 1833) was a British inventor and mining engineer. The son of a mining captain, and born in the mining heartland of Cornwall, Trevithick was immersed in mining and engineering from an early age. He was an early pioneer of steam-powered road and rail transport, and his most significant contributions were the development of the first high-pressure steam engine and the first working railway steam locomotive. The world's first locomotive-hauled railway journey took place on 21 February 1804, when Trevithick's unnamed steam locomotive hauled a train along the tramway of the Penydarren Ironworks, in Merthyr Tydfil, Wales. Turning his interests abroad Trevithick also worked as a mining consultant in Peru and later explored parts of Costa Rica. Throughout his professional career he went through many ups and downs and at one point faced financial ruin, also suffering from the strong rivalry of many mining and steam engineers of the day.

Historic Railway In The Beamish Museum 06
History is the systematic study of the past, focusing primarily on the human past. As an academic discipline, it analyses and interprets evidence to construct narratives about what happened and explain why it happened. Some theorists categorize history as a social science, while others see it as part of the humanities or consider it a hybrid discipline. Similar debates surround the purpose of history—for example, whether its main aim is theoretical, to uncover the truth, or practical, to learn lessons from the past. In a more general sense, the term ''history'' refers not to an academic field but to the past itself, times in the past, or to individual texts about the past. Historical research relies on primary and secondary sources to reconstruct past events and validate interpretations. Source criticism is used to evaluate these sources, assessing their authenticity, content, and reliability. Historians strive to integrate the perspectives of several sources to develop a ...
