Windpump
A windpump is a type of windmill which is used for pumping water. Windpumps were used to pump water since at least the 9th century in what is now Afghanistan, Iran and Pakistan. The use of wind pumps became widespread across the Muslim world and later spread to China and Indian subcontinent, India. Windmills were later used extensively in Europe, particularly in the Netherlands and the East Anglia area of Great Britain, from the late Middle Ages onwards, to drain land for agricultural or building purposes. Simon Stevin's work in the ''waterstaet'' involved improvements to the sluices and spillways to control flooding. Windmills were already in use to pump the water out, but in ''Van de Molens'' (''On mills''), he suggested improvements, including the idea that the wheels should move slowly, and a better system for meshing of the gear teeth. These improvements increased the efficiency of the windmills used to pump water out of the polders by three times. He received a patent on h ...

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] |
Rijksmonuments In Friesland
A rijksmonument (, ) is a national heritage site of the Netherlands, listed by the agency Rijksdienst voor het Cultureel Erfgoed (RCE) acting for the Dutch Ministry of Education, Culture and Science. At the end of February 2015, the Netherlands had 61,822 listed national heritage sites, of which approximately 1,500 are listed as archaeological sites. History and criteria Until 2012, a place had to be over 50 years old to be eligible for designation. This criterion expired on 1 January 2012. The current legislation governing the monuments is the ''Monumentenwet van 1988'' ("Monument Law of 1988"). The organization responsible for caring for the monuments, which used to be called ''Monumentenzorg'', was recently renamed, and is now called Rijksdienst voor het Cultureel Erfgoed. In June 2009, the Court of The Hague decided that individual purchasers of buildings that were listed as rijksmonuments would be exempt from paying transfer tax, effective from 1 May 2009.

Windmills Completed In 1878
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 ...

Post Mill
The post mill is the earliest type of European windmill. Its defining feature is that the whole body of the mill that houses the machinery is mounted on a single vertical post, around which it can be turned to bring the sails into the wind. All post mills have an arm projecting from them on the side opposite the sails and reaching down to near ground level. With some, as at Saxtead Green, the arm carries a fantail to turn the mill automatically. With the others the arm serves to rotate the mill into the wind by hand. The earliest post mills in England are thought to have been built in the 12th century. The earliest working post mill in England still used today is to be found at Outwood, Surrey. It was built in 1665. The earliest remaining example of a non-operational mill can be found in Great Gransden in Cambridgeshire, built in 1612.Windmills in Huntingdon and Peterborough. p. 3.

Smock Mill
The smock mill is a type of windmill that consists of a sloping, horizontally weatherboarded, thatched, or shingled tower, usually with six or eight sides. It is topped with a roof or cap that rotates to bring the sails into the wind. This type of windmill got its name from its resemblance to smocks worn by farmers in an earlier period. Construction Smock mills differ from tower mills, which are usually cylindrical rather than hexagonal or octagonal, and built from brick or stone masonry instead of timber. The majority of smock mills are octagonal in plan, with a lesser number hexagonal in plan, such as Killick's Mill, Meopham. A very small number of smock mills were decagonal or dodecagonal in plan, an example of the latter being at Wicken, Cambridgeshire. Distribution Smock mills exist in Europe and particularly in England, where they were common, particularly in the county of Kent, where the tallest surviving smock mill in the United Kingdom, Union Mill, can be found a ...
