House-built Engine
A house-built engine is a stationary steam engine that is built into an engine house, such that it uses the masonry of the engine house as an integral part of the support of the engine. Beam engines Most house-built engines were early beam engines. A 'bob wall' in the engine house supported the pivot axle of the beam or 'bob'. This wall could be an internal wall, with both ends of the beam inside the house, but it was commonly the end wall of the house and so the beam projected to the outside. For a heavy beam, the bob wall was required to be extremely substantial. Early engines were used for pumping mines or wells, so as well as the weight of the beam, the house had to also support the weight of the long pump rod, reaching down to the depths of the mine. Beam engines appeared during the 18th century. The only technologies at this time that could support the weight of an engine's beam were masonry and timber-framing, as the work of either shipwrights or millwrights. Cast iro ...

Alden Valley
The Alden Valley is a small valley on the eastern edge of the West Pennine Moors, west of Helmshore in Rossendale, Lancashire, England. In the 14th century it was part of the Earl of Lincoln's hunting park. By 1840 it was home to about twenty farms, largely involved in cattle rearing, although most inhabitants were also involved with the production of textiles, which quickly developed during the Industrial Revolution into the building of textile mills. These have now been demolished and the valley is dominated by sheep grazing, with three working farms and a number of smallholdings. To the north and north-west is Musbury Tor, to the south-west at the head of the valley is Scholes Height, to the west is Musden Head Moor and Burnt Hill. To the south is Bull Hill and the Holcombe Moor, to the south-east is Beetle Hill. Alden Brook forms from several streams draining Wet Moss on the north-western slopes of Scholes Height, which join after flowing through several gullies at an area know ...

Robey & Co
Robey and Co. was an engineering company based in Lincoln, England which can be traced back to at least 1849. In 1854 Watkinson and Robey ''Engineers and Millwrights'' were manufacturing Portable Engines and machinery of every description in Rumbold Street, Lincoln. They were joined by George Lamb Scott, but in 1855 Watkinson, who had previously worked for Clayton & Shuttleworth of Lincoln, left the company. The business then became Robey and Scott and moved their premises by 1856 to Canwick Road, Lincoln. Another partner, Thomas Gamble, joined the firm and Scott resigned in September 1856 to found his own manufacturing company in Manchester. The company then became Gamble & Robey, but by 1868 was known as Robey & Co Ltd. Robert Robey died in 1876 and the firm continued as a partnership led by John Richardson. In 1893 Robey & Co became a limited company. By 1913 Robeys were makers of steam motor wagons, tractors and ploughs and in the First World War manufactured aircraft. T ...

High-speed Steam Engine
High-speed steam engines were one of the final developments of the stationary steam engine. They ran at a high speed, of several hundred rpm,, 400 to 1,200 rpm which was needed by tasks such as electricity generation. Defining characteristics They have two primary characteristics: * High speed. : This is sufficient to drive a small dynamo directly, rather than needing a step-up drive by belts. * Accurate speed regulation. : Generation by dynamo requires a stable rotation speed for a stable output voltage, even when the load changes. When an alternator was being driven, the output frequency also depended upon a stable rotation speed. These also resulted in a number of secondary characteristics. Although these were not defining to the type, or were always the case, they were recognisably common: * Improved lubrication, as required by their high speed. : This often used an enclosed crankcase with an oil sump and lubrication by 'splash' or by ring oilers. Some went so far as to ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Ashlar
Ashlar () is finely dressed (cut, worked) stone, either an individual stone that has been worked until squared, or a structure built from such stones. Ashlar is the finest stone masonry unit, generally rectangular cuboid, mentioned by Vitruvius as opus isodomum, or less frequently trapezoidal. Precisely cut "on all faces adjacent to those of other stones", ashlar is capable of very thin joints between blocks, and the visible face of the stone may be quarry-faced or feature a variety of treatments: tooled, smoothly polished or rendered with another material for decorative effect. One such decorative treatment consists of small grooves achieved by the application of a metal comb. Generally used only on softer stone ashlar, this decoration is known as "mason's drag". Ashlar is in contrast to rubble masonry, which employs irregularly shaped stones, sometimes minimally worked or selected for similar size, or both. Ashlar is related but distinct from other stone masonry that is ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Engineering Brick
Engineering bricks are a type of brick used where strength, low water porosity or acid (flue gas) resistance are needed. Engineering bricks can be used for damp-proof courses. Clay engineering bricks are defined in ''§ 6.4.51'' of ''British Standard BS ISO 6707-1;2014 (buildings & civil engineering works - vocabulary - general terms)'' as "fire-clay brick that has a dense and strong semi-vitreous body and which conforms to defined limits for water absorption and compressive strength" Stronger and less porous engineering bricks (UK Class A) are usually blue due to the higher firing temperature whilst class B bricks are usually red. Class A bricks have a strength of and water absorption of less than 4.5%; Class B bricks have a strength greater than and water absorption of less than 7%. Accrington brick is a type of engineering brick that was used in the construction of the foundations in the Empire State Building The Empire State Building is a 102-story Art Deco skyscra ...

Cast Iron
Cast iron is a class of iron–carbon alloys with a carbon content more than 2%. Its usefulness derives from its relatively low melting temperature. The alloy constituents affect its color when fractured: white cast iron has carbide impurities which allow cracks to pass straight through, grey cast iron has graphite flakes which deflect a passing crack and initiate countless new cracks as the material breaks, and ductile cast iron has spherical graphite "nodules" which stop the crack from further progressing. Carbon (C), ranging from 1.8 to 4 wt%, and silicon (Si), 1–3 wt%, are the main alloying elements of cast iron. Iron alloys with lower carbon content are known as steel. Cast iron tends to be brittle, except for malleable cast irons. With its relatively low melting point, good fluidity, castability, excellent machinability, resistance to deformation and wear resistance, cast irons have become an engineering material with a wide range of applications and are ...

Henry Maudslay
Henry Maudslay ( pronunciation and spelling) (22 August 1771 – 14 February 1831) was an English machine tool innovator, tool and die maker, and inventor. He is considered a founding father of machine tool technology. His inventions were an important foundation for the Industrial Revolution. Maudslay's invention of a metal lathe to cut metal, circa 1800, enabled the manufacture of standard screw thread sizes. Standard screw thread sizes allowed interchangeable parts and the development of mass production. Early life Maudslay was the fifth of seven children of Henry Maudslay, a wheelwright in the Royal Engineers, and Margaret (''nee'' Whitaker), the young widow of Joseph Laundy. His father was wounded in action and so in 1756 became an 'artificer' at the Royal Arsenal, Woolwich (then in Kent), where he remained until 1776 and died in 1780. The family lived in an alley that no longer exists, off Beresford Square, between Powis Street and Beresford Street. Career Maudslay be ...

James Sadler (balloonist)
James Sadler (February 1753 – 28 March 1828) was the first English balloonist, as well as a chemist and pastry chef. Life Sadler worked as a pastry chef in the family business, The Lemon Hall Refreshment House, a small shop in Oxford. Sadler was the second person to make a balloon ascent in England, very soon after the Tuscan Vincent Lunardi's flight on 15 September 1784 in the grounds of the Honourable Artillery Company at Moorfields. James Sadler was still the first English Aeronaut, making his ascent the following month, on 4 October 1784 from Christ Church Meadow, Oxford. The balloon rose to about and landed near Woodeaton, around away. Sadler's second ascent occurred on 12 November, this time in a hydrogen-filled balloon. It reached Aylesbury in Buckinghamshire after a twenty-minute flight. In May of the following year he took off near Moulsey Hurst, Surrey, accompanied by W. Wyndham MP, hoping to reach France, but in fact descending in the Thames Estuary, and t ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
