Barnet Gate Mill
Barnet Gate Mill or Arkley Windmill is a grade II* listed tower mill at Barnet Gate in the London Borough of Barnet, originally in Hertfordshire. There is no public access. History Barnet Gate Mill was probably built between 1822 and 1840. A claim that it was built during the Napoleonic Wars (c.1800) has not been substantiated. Although steam had been added in 1895, it was working by wind until 1916. The mill was restored in 1930. A new cap, fantail and gallery around the cap being made. The work was done by Thomas Hunt, the Soham millwright. In a further restoration in 1985, the missing pair of sails was replaced. Description Barnet Gate Mill is a four-storey tower mill with an ogee cap which has a gallery. It has two Patent sails and two Common sails carried on a cast iron Cast iron is a class of iron– carbon alloys with a carbon content more than 2%.

Grist Mill
A gristmill (also: grist mill, corn mill, flour mill, feed mill or feedmill) grinds cereal grain into flour and Wheat middlings, middlings. The term can refer to either the Mill (grinding), grinding mechanism or the building that holds it. Grist is grain that has been separated from its chaff in preparation for grinding. History Early history The Greek geographer Strabo reports in his ''Geography'' a water-powered grain-mill to have existed near the palace of king Mithradates VI Eupator at Cabira, Asia Minor, before 71 BC. The early mills had horizontal paddle wheels, an arrangement which later became known as the "Water wheel#Vertical axis, Norse wheel", as many were found in Scandinavia. The paddle wheel was attached to a shaft which was, in turn, attached to the centre of the millstone called the "runner stone". The turning force produced by the water on the paddles was transferred directly to the runner stone, causing it to grind against a stationary "Mill machinery#Wat ...

Soham
Soham ( ) is a town and civil parish in the district of East Cambridgeshire, in Cambridgeshire, England, just off the A142 between Ely and Newmarket. Its population was 10,860 at the 2011 census. History Archaeology The region between Devil's Dyke and the line between Littleport and Shippea Hill shows a remarkable amount of archaeological findings of the Stone Age, the Bronze Age and the Iron Age. A couple of hoards of bronze objects are found in the area of Soham, including one with swords and spearheads of the later Bronze Age as well as a gold torc, retrieved in 1938. A large Anglo-Saxon settlement was discovered on land between Brook Street and Fordham Road, next to Roman remains in the old Fisky's Hill area and former allotment site in 2013 and onwards. During the establishment of the Fordham Road cemetery, in the late 1800's, burial remains were also found with several high-status grave goods, including a girdle hanger, beads and Jewlery. These items are now housed ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Tourist Attractions In The London Borough Of Barnet
Tourism is travel for pleasure or business; also the theory and practice of touring, the business of attracting, accommodating, and entertaining tourists, and the business of operating tours. The World Tourism Organization defines tourism more generally, in terms which go "beyond the common perception of tourism as being limited to holiday activity only", as people "travelling to and staying in places outside their usual environment for not more than one consecutive year for leisure and not less than 24 hours, business and other purposes". Tourism can be domestic (within the traveller's own country) or international, and international tourism has both incoming and outgoing implications on a country's balance of payments. Tourism numbers declined as a result of a strong economic slowdown (the late-2000s recession) between the second half of 2008 and the end of 2009, and in consequence of the outbreak of the 2009 H1N1 influenza virus, but slowly recovered until the COVID-19 ...

Windmills In London
A windmill is a structure that converts wind power into rotational energy using vanes called sails or blades, specifically to mill grain (gristmills), but the term is also extended to windpumps, wind turbines, and other applications, in some parts of the English speaking world. The term wind engine is sometimes used to describe such devices. Windmills were used throughout the high medieval and early modern periods; the horizontal or panemone windmill first appeared in Persia during the 9th century, and the vertical windmill first appeared in northwestern Europe in the 12th century. Regarded as an icon of Dutch culture, there are approximately 1,000 windmills in the Netherlands today. Forerunners Wind-powered machines may have been known earlier, but there is no clear evidence of windmills before the 9th century. Hero of Alexandria (Heron) in first-century Roman Egypt described what appears to be a wind-driven wheel to power a machine.Dietrich Lohrmann, "Von der östlichen z ...

Tower Mills In The United Kingdom
A tower is a tall structure, taller than it is wide, often by a significant factor. Towers are distinguished from masts by their lack of guy-wires and are therefore, along with tall buildings, self-supporting structures. Towers are specifically distinguished from buildings in that they are built not to be habitable but to serve other functions using the height of the tower. For example, the height of a clock tower improves the visibility of the clock, and the height of a tower in a fortified building such as a castle increases the visibility of the surroundings for defensive purposes. Towers may also be built for observation, leisure, or telecommunication purposes. A tower can stand alone or be supported by adjacent buildings, or it may be a feature on top of a larger structure or building. Etymology Old English ''torr'' is from Latin ''turris'' via Old French ''tor''. The Latin term together with Greek τύρσις was loaned from a pre-Indo-European Mediterranean langua ...

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 ...

Millwright
A millwright is a craftsperson or skilled tradesperson who installs, dismantles, maintains, repairs, reassembles, and moves machinery in factories, power plants, and construction sites. The term ''millwright'' (also known as ''industrial mechanic'') is mainly used in the United States, Canada and South Africa to describe members belonging to a particular trade. Other countries use different terms to describe tradesmen engaging in similar activities. Related but distinct crafts include machinists, mechanics and mechanical fitters . As the name suggests, the original function of a millwright was the construction of flour mills, sawmills, paper mills and fulling mills powered by water or wind, made mostly of wood with a limited number of metal parts. Since the use of these structures originates in antiquity, millwrighting could arguably be considered one of the oldest engineering trades and the forerunner of modern mechanical engineering. In modern usage, a millwright is engaged ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
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] |
Tower Mill
A tower mill is a type of vertical windmill consisting of a brick or stone tower, on which sits a wooden 'cap' or roof, which can rotate to bring the sails into the wind.Medieval science, technology, and medicine: an encyclopedia (2005), 520 This rotating cap on a firm masonry base gave tower mills great advantages over earlier post mills, as they could stand much higher, bear larger sails, and thus afford greater reach into the wind. Windmills in general had been known to civilization for centuries, but the tower mill represented an improvement on traditional western-style windmills. The tower mill was an important source of power for Europe for nearly 600 years from 1300 to 1900, contributing to 25 percent of the industrial power of all wind machines before the advent of the steam engine and coal power. It represented a modification or a demonstration of improving and adapting technology that had been known by humans for ages. Although these types of mills were effectiv ...
