De Ikkers
De Akkers is a hollow post mill in Wartena, Friesland, Netherlands which was built in 1970 and has been restored so that it can turn in the wind. It is listed as a Rijksmonument. History ''De Akkers'' was built in the 18th century. In 1921, it was moved to Snikzwaag, Friesland to replace a tjasker. In 1970, the derelict mill was bought by the Stichting Langebrück, Amsterdam, North Holland. It was moved to Wartena and restored. A similar mill, the ''Saitermolen'', had previously stood on the site. The mill was restored in 1986 by millwright Westra of Franeker, Friesland. The mill is listed as a Rijksmonument, №22934. Description ''De Deels'' is what the Dutch describe as a ''Spinnekopmolen''. It is a hollow post mill on a single storey roundhouse. The mill is winded by a winch. The sails are Common sails. They have a span of . The sails are carried on a wooden ''windshaft''. The ''windshaft'' carries the ''brake wheel'' which has 27 cogs. This drives the ''wallower'' (15 cogs) ...

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 ...

Windmills Completed In 1970
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 östli ...

Franeker
Franeker (; fry, Frjentsjer) is one of the eleven historical cities of Friesland and capital of the municipality of Waadhoeke. It is located north of the Van Harinxmakanaal and about 20 km west of Leeuwarden. As of 1 January 2014, it had 12,781 inhabitants. The Eise Eisinga Planetarium, established in 1781, is located in the city. History Franeker was founded around 800 as a Carolingian stronghold. The name probably derives from ''Froon-acker'', meaning "land of the lord/king"; the oldest street in the city is still called Froonacker. Beginning around the 11th century, Franeker developed into the administrative center Westergoa. Franeker received city rights in 1374. In the 15th century, Albert, Duke of Saxony established himself in Franeker. The city appeared for a time to be growing into the primary city of Friesland, but was eventually overshadowed in this role by Leeuwarden. During the period of the Dutch Revolt, the town sided early on with William I. From 1585 to ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
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] |

North Holland ( nl, Noord-Holland, ) is a province of the Netherlands in the northwestern part of the country. It is located on the North Sea, north of South Holland and Utrecht, and west of Friesland and Flevoland. In November 2019, it had a population of 2,877,909 and a total area of , of which is water. From the 9th to the 16th century, the area was an integral part of the County of Holland. During this period West Friesland was incorporated.

Tjasker
The tjasker (West Frisian: , German: ) is a small type of windmill used solely for drainage purposes. It is distinctive for its simple construction, featuring only a single inclined shaft that carries the sails on one end and an Archimedes' screw on the other, in this way avoiding the need for any gearing. The tjasker is commonly known as a typical Frisian windmill though it is also found in other Dutch provinces and in north Germany. History The tjasker seems to have been developed somewhere towards the end of the 16th century, though there is no conclusive date for its invention. The total number of tjaskers at their peak is also unclear. The mills were used to drain small plots of land but also found their use at peat digging sites as they could be easily moved. Millwright R.W. Dijksma of Giethoorn was well known for his tjasker building. He constructed 400 to 500 tjaskers between 1910 and 1945, though these numbers include hand powered Archimedes' screws.

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.
