William McNaught (Rochdale)
William McNaught ( - 1888) was a steam engine engineer from Rochdale, Lancashire, England. McNaught was born in Manchester in ( and apprenticed with a Mr Mills of Heywood, Greater Manchester, Heywood, Bury, Greater Manchester, Bury. He then worked in London for John & Thomas Rennie before coming to Alexander Petrie & Son, around 1838. McNaught became chief designer and superintendent at James Petrie's and designed a Cutoff (steam engine), cutoff gear for use on a stationary steam engine. This was patented by James Petrie in 1844. Petrie started to build mill engines in 1819, McNaught joined in 1838 and remained until 1858, when he started his own company. Before this patent, there were problems with slide valves which suffered excessive wear. The Petrie and McNaught cutoff valves were circular with sloping faces that allowed a variable cut-off; they could be easily connected to the Governor (device), governor that McNaught patented in 1850. In 1860 he left Petrie's to set u ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Museum Of Science And Industry, Manchester 2017 003
A museum ( ; plural museums or, rarely, musea) is a building or institution that Preservation (library and archival science), cares for and displays a collection (artwork), collection of artifacts and other objects of artistic, culture, cultural, history, historical, or science, scientific importance. Many public museums make these items available for public viewing through display case, exhibits that may be permanent or temporary. The largest museums are located in major cities throughout the world, while thousands of local museums exist in smaller cities, towns, and rural areas. Museums have varying aims, ranging from the conservation and documentation of their collection, serving researchers and specialists, to catering to the general public. The goal of serving researchers is not only scientific, but intended to serve the general public. There are many types of museums, including art museums, natural history museums, science museums, war museums, and children's museums. Ac ...

Steam Engine
A steam engine is a heat engine that performs mechanical work using steam as its working fluid. The steam engine uses the force produced by steam pressure to push a piston back and forth inside a cylinder. This pushing force can be transformed, by a connecting rod and crank, into rotational force for work. The term "steam engine" is generally applied only to reciprocating engines as just described, not to the steam turbine. Steam engines are external combustion engines, where the working fluid is separated from the combustion products. The ideal thermodynamic cycle used to analyze this process is called the Rankine cycle. In general usage, the term ''steam engine'' can refer to either complete steam plants (including boilers etc.), such as railway steam locomotives and portable engines, or may refer to the piston or turbine machinery alone, as in the beam engine and stationary steam engine. Although steam-driven devices were known as early as the aeolipile in the f ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Rochdale
Rochdale ( ) is a large town in Greater Manchester, England, at the foothills of the South Pennines in the dale on the River Roch, northwest of Oldham and northeast of Manchester. It is the administrative centre of the Metropolitan Borough of Rochdale, which had a population of 211,699 in the 2011 census. Located within the historic boundaries of the county of Lancashire. Rochdale's recorded history begins with an entry in the Domesday Book of 1086 under "Recedham Manor". The ancient parish of Rochdale was a division of the hundred of Salford and one of the largest ecclesiastical parishes in England, comprising several townships. By 1251, Rochdale had become important enough to have been granted a Royal charter. Rochdale flourished into a centre of northern England's woollen trade, and by the early 18th century was described as being "remarkable for many wealthy merchants". Rochdale rose to prominence in the 19th century as a mill town and centre for textile manufacture ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Heywood, Greater Manchester
Heywood is a town in the Metropolitan Borough of Rochdale, Greater Manchester, England, in the historic county of Lancashire. It had a population of 28,205 at the 2011 Census. The town lies on the south bank of the River Roch, east of Bury, southwest of Rochdale, and north of Manchester. Middleton lies to the south, whilst to the north is the Cheesden Valley, open moorland, and the Pennines. Heywood's nickname is Monkey Town. The Anglo-Saxons cleared the densely wooded area, dividing it into heys or fenced clearings. In the Middle Ages, Heywood formed a chapelry in the township, around Heywood Hall, a manor house owned by a family with that surname. Farming was the main industry of a sparsely populated rural area. The population supplemented their incomes by hand-loom woollen weaving in the domestic system. The factory system in the town can be traced to a spinning mill in the late 18th century. Following the introduction of textile manufacture during the Industrial R ...

Bury, Greater Manchester
Bury ( ) is a market town on the River Irwell in Greater Manchester, England. Metropolitan Borough of Bury is administered from the town, which had an estimated population of 78,723 in 2015. The town is within the historic county boundaries of Lancashire. It emerged in the Industrial Revolution as a mill town manufacturing textiles. The town is known for the open-air Bury Market and black pudding, the traditional local dish. Sir Robert Peel was born in the town. Peel was a Prime Minister of the United Kingdom who founded the Metropolitan Police and the Conservative Party. A memorial and monument for Peel, the former stands outside Bury parish church and the latter overlooks the borough on Holcombe Hill. The town is east of Bolton and southwest of Rochdale. It is northwest of Manchester, having a Manchester Metrolink tram terminus.

Cutoff (steam Engine)
In a steam engine, cutoff is the point in the piston stroke at which the inlet valve is closed. On a steam locomotive, the cutoff is controlled by the reversing gear. The point at which the inlet valve closes and stops the entry of steam into the cylinder from the boiler plays a crucial role in the control of a steam engine. Once the valve has closed, steam trapped in the cylinder expands adiabatically. The steam pressure drops as it expands. A late cutoff delivers full steam pressure to move the piston through its entire stroke, for maximum start-up forces. But, since there will still be unexploited pressure in the cylinder at the end of the stroke, this is achieved at the expense of engine efficiency. In this situation the steam will still have considerable pressure remaining when it is exhausted resulting in the characteristic “chuff chuff” sound of a steam engine. An early cutoff has greater thermodynamic efficiency but results in a lower Mean effective pressure so less ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Stationary Steam Engine
Stationary steam engines are fixed steam engines used for pumping or driving mills and factories, and for power generation. They are distinct from locomotive engines used on railways, traction engines for heavy steam haulage on roads, steam cars (and other motor vehicles), agricultural engines used for ploughing or threshing, marine engines, and the steam turbines used as the mechanism of power generation for most nuclear power plants. They were introduced during the 18th century and widely made for the whole of the 19th century and most of the first half of the 20th century, only declining as electricity supply and the internal combustion engine became more widespread. Types of stationary steam engine There are different patterns of stationary steam engines, distinguished by the layout of the cylinders and crankshaft: * Beam engines have a rocking beam providing the connection between the vertical cylinder and crankshaft. *Table engines have the crosshead above the vert ...

Slide Valve
The slide valve is a rectilinear valve used to control the admission of steam into and emission of exhaust from the cylinder of a steam engine. Use In the 19th century, most 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: * With piston valves, the steam passages can be made shorter. This reduces resistance to the flow of steam and improves efficiency. * It is difficult to lubricate slide valves adequately in the presence of superheated steam. Murdoch's D slide valve The D slide valve, or more specifically Long D slide valve, is a form of slide valve, invented by William Murdoch and patented in 1799. It is named after the hollow central D-sectioned piston. This valve worked by "connecting the upper and lower valves so as to be worked by one rod or spindle, and in maki ...

Governor (device)
A governor, or speed limiter or controller, is a device used to measure and regulate the speed of a machine, such as an engine. A classic example is the centrifugal governor, also known as the Watt or fly-ball governor on a reciprocating steam engine, which uses the effect of inertial force on rotating weights driven by the machine output shaft to regulate its speed by altering the input flow of steam. History Centrifugal governors were used to regulate the distance and pressure between millstones in windmills since the 17th century. Early steam engines employed a purely reciprocating motion, and were used for pumping water – an application that could tolerate variations in the working speed. It was not until the Scottish engineer James Watt introduced the ''rotative'' steam engine, for driving factory machinery, that a constant operating speed became necessary. Between the years 1775 and 1800, Watt, in partnership with industrialist Matthew Boulton, produced some 500 ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
