Swan Lane Mills
Swan Lane Mills is a former cotton mill complex in Bolton, Greater Manchester. All three mills are Grade II* listed buildings. The mills were designed by Stott and Sons of Oldham. When completed, the double mill (Nos. 1 and 2) was the largest spinning mill in the world. It was granted Grade II* listed status on 26 April 1974. Number 3 Mill was separately listed as Grade II* on the same day. History Swan Lane Mills are typical of the final phase of cotton mill construction in Lancashire, of vast size and decorated with flamboyant terracotta embellishments reflecting the industry's prominence and prosperity. The mill was planned as a double mill with a central boiler house and built in two phases. Swan Lane Number 1 Mill was built in 1902, and Number 2 Mill three years later. The double mill was built to contain 210,000 mule spindles. Number 3 Mill was built in 1915 and housed 120,000 mule spindles. Number 1 Mill spun fine counts using Sea Island Cotton and Number 2 Mill concentrat ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Swan Lane Mills Bolton - Geograph
Swans are birds of the family Anatidae within the genus ''Cygnus''. The swans' closest relatives include the geese and ducks. Swans are grouped with the closely related geese in the subfamily Anserinae where they form the tribe Cygnini. Sometimes, they are considered a distinct subfamily, Cygninae. There are six living and many extinct species of swan; in addition, there is a species known as the coscoroba swan which is no longer considered one of the true swans. Swans usually mate for life, although "divorce" sometimes occurs, particularly following nesting failure, and if a mate dies, the remaining swan will take up with another. The number of eggs in each clutch ranges from three to eight. Etymology and terminology The English word ''swan'', akin to the German , Dutch and Swedish , is derived from Indo-European root ' ('to sound, to sing'). Young swans are known as '' cygnets'' or as '' swanlings''; the former derives via Old French or (diminutive suffix et 'little') from ...

Parapet
A parapet is a barrier that is an extension of the wall at the edge of a roof, terrace, balcony, walkway or other structure. The word comes ultimately from the Italian ''parapetto'' (''parare'' 'to cover/defend' and ''petto'' 'chest/breast'). Where extending above a roof, a parapet may simply be the portion of an exterior wall that continues above the edge line of the roof surface, or may be a continuation of a vertical feature beneath the roof such as a fire wall or party wall. Parapets were originally used to defend buildings from military attack, but today they are primarily used as guard rails, to conceal rooftop equipment, reduce wind loads on the roof, and to prevent the spread of fires. In the Bible the Hebrews are obligated to build a parapet on the roof of their houses to prevent people falling (Deuteronomy 22:8). Parapet types Parapets may be plain, embattled, perforated or panelled, which are not mutually exclusive terms. *Plain parapets are upward extensions of ...

Rope Drive
A rope drive is a form of belt drive, used for mechanical power transmission. Rope drives use a number of circular section ropes, rather than a single flat or vee belt. Multiple rope drive The first multiple rope drive was a 9-rope drive of 200 bhp produced by Combe Barbour for their Falls Foundry, Belfast, in 1863. James Combe experimented first with circular ropes laid from leather strips, then from manila hemp. The idea of using rope drives had arisen from his earlier, 1856, experiments in using a rope drive together with an expanding vee pulley, as part of a Van Doorne or Variomatic transmission. Combe Barbour were makers of textile machinery and differential speed gearing was often needed as part of the spinning process, where one shaft could be smoothly adjusted to run slightly faster or slower than another. Usage Rope drives were most widely used for power-transmission in mills and factories, where a single mill engine would have a large rope drive to ea ...

Flywheel
A flywheel is a mechanical device which uses the conservation of angular momentum to store rotational energy; a form of kinetic energy proportional to the product of its moment of inertia and the square of its rotational speed. In particular, assuming the flywheel's moment of inertia is constant (i.e., a flywheel with fixed mass and second moment of area revolving about some fixed axis) then the stored (rotational) energy is directly associated with the square of its rotational speed. Since a flywheel serves to store mechanical energy for later use, it is natural to consider it as a kinetic energy analogue of an electrical inductor. Once suitably abstracted, this shared principle of energy storage is described in the generalized concept of an accumulator. As with other types of accumulators, a flywheel inherently smooths sufficiently small deviations in the power output of a system, thereby effectively playing the role of a low-pass filter with respect to the mechanical velocity ...

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 stea ...

Compound Steam Engine
A compound steam engine unit is a type of steam engine where steam is expanded in two or more stages. A typical arrangement for a compound engine is that the steam is first expanded in a high-pressure ''(HP)'' cylinder, then having given up heat and losing pressure, it exhausts directly into one or more larger-volume low-pressure ''(LP)'' cylinders. Multiple-expansion engines employ additional cylinders, of progressively lower pressure, to extract further energy from the steam. Invented in 1781, this technique was first employed on a Cornish beam engine in 1804. Around 1850, compound engines were first introduced into Lancashire textile mills. Compound systems There are many compound systems and configurations, but there are two basic types, according to how HP and LP piston strokes are phased and hence whether the HP exhaust is able to pass directly from HP to LP ( Woolf compounds) or whether pressure fluctuation necessitates an intermediate "buffer" space in the form of a st ...

George Saxon & Co
George Saxon & Co was an English engineering company that manufactured stationary steam engines. It was based in the Openshaw district of Greater Manchester, Manchester. The company produced large steam-driven engines for power stations and later for Cotton mill, textile mills in Lancashire and elsewhere. Biography George Saxon was born in Manchester in 1821. He served an apprenticeship with William Fairbairn and rose to supervisor. In 1851, he moved to be foreman at Benjamin Goodfellow's works in Hyde, Greater Manchester. Here in 1854, he invented and patented a fusible plug for steam boilers. That year he formed his own business at Spring Works, Openshaw, trading as George Saxon. He was a mill-wright. He probably started manufacturing steam engines in 1860. He patented many small improvements to engine design. He was elected president of the Manchester Association of Engineers in 1871. He was also a member of the Institute of Mechanical Engineers. In February 1879 he patented ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Pinnacle
A pinnacle is an architectural element originally forming the cap or crown of a buttress or small turret, but afterwards used on parapets at the corners of towers and in many other situations. The pinnacle looks like a small spire. It was mainly used in Gothic architecture. The pinnacle had two purposes: # Ornamental – adding to the loftiness and verticity of the structure. They sometimes ended with statues, such as in Milan Cathedral. # Structural – the pinnacles were very heavy and often rectified with lead, in order to enable the flying buttresses to contain the stress of the structure vaults and roof. This was done by adding compressive stress (a result of the pinnacle weight) to the thrust vector and thus shifting it downwards rather than sideways. History The accounts of Jesus' temptations in Matthew's and Luke's gospels both suggest that the Second Temple in Jerusalem had one or more pinnacles ( gr, το πτερυγιον του ιερου): :Then he (Satan) br ...

Corbel
In architecture, a corbel is a structural piece of stone, wood or metal jutting from a wall to carry a superincumbent weight, a type of bracket. A corbel is a solid piece of material in the wall, whereas a console is a piece applied to the structure. A piece of timber projecting in the same way was called a "tassel" or a "bragger" in England. The technique of corbelling, where rows of corbels deeply keyed inside a wall support a projecting wall or parapet, has been used since Neolithic (New Stone Age) times. It is common in medieval architecture and in the Scottish baronial style as well as in the vocabulary of classical architecture, such as the modillions of a Corinthian cornice. The corbel arch and corbel vault use the technique systematically to make openings in walls and to form ceilings. These are found in the early architecture of most cultures, from Eurasia to Pre-Columbian architecture. A console is more specifically an "S"-shaped scroll bracket in the classic ...

Decorative Entrance - Geograph
Beauty is commonly described as a feature of objects that makes these objects pleasurable to perceive. Such objects include landscapes, sunsets, humans and works of art. Beauty, together with art and taste, is the main subject of aesthetics, one of the major branches of philosophy. As a positive aesthetic value, it is contrasted with Unattractiveness, ugliness as its negative counterpart. Along with truth and Value (ethics), goodness it is one of the transcendentals, which are often considered the three fundamental concepts of human understanding. One difficulty in understanding beauty is because it has both objective and subjective aspects: it is seen as a property of things but also as depending on the emotional response of observers. Because of its subjective side, beauty is said to be "in the eye of the beholder". It has been argued that the ability on the side of the subject needed to perceive and judge beauty, sometimes referred to as the "sense of taste", can be trained ...

Carding
Carding is a mechanical process that disentangles, cleans and intermixes fibres to produce a continuous web or sliver (textiles), sliver suitable for subsequent processing. This is achieved by passing the fibres between differentially moving surfaces covered with "card clothing", a firm flexible material embedded with metal pins. It breaks up locks and unorganised clumps of fibre and then aligns the individual fibres to be parallel with each other. In preparing wool fibre for spinning, carding is the step that comes after teasing. The word is derived from the Latin meaning thistle or Dipsacus, teasel, as dried vegetable teasels were first used to comb the raw wool before technological advances led to the use of machines. Overview These ordered fibres can then be passed on to other processes that are specific to the desired end use of the fibre: Cotton mill, Cotton, Batting (material), batting, felt, woollen or worsted yarn, etc. Carding can also be used to create blends of dif ...
