De Achlumer Molen, Achlum
De Achlumer Molen is a smock mill in Achlum, Friesland, Netherlands which has been restored to working order. The mill is listed as a Rijksmonument, number 15821. History De Achlumer Molen was built in 1851 to drain the Achlumer Noorderpolder. It worked by wind until 1954 when the cap and sails were removed and the smock tower fitted with a thatched conical roof. After that, an electric motor drove the Archimedes' screw. In 1981, the mill was bought by Stichting De Fryske Mole (English: ''The Frisian Mills Foundation''). The previous owner, Haye Thomas, a Dutch TV journalist, sold the mill for ƒ1. In September 2006 it was decided to restore the mill. The work was undertaken in the summer of 2007. (Click on ''Geschiedenis" to view.) On 18 October 2007 the new cap and sails were fitted to the mill. The restoration was carried out by Bouwbedrijf Hiemsta of Arum. Description De Achlumer Molen is what the Dutch describe as an ''achtkante grondzeiler'' – a smock mill whose sails ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
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 at ...

Dutch Guilder
The guilder ( nl, gulden, ) or florin was the currency of the Netherlands from the 15th century until 2002, when it was replaced by the euro. The Dutch name ''gulden'' was a Middle Dutch adjective meaning "golden", and reflects the fact that, when first introduced in 1434, its value was about equal to (i.e., it was on par with) the Italian gold florin. The Dutch guilder was a ''de facto'' reserve currency in Europe in the 17th and 18th centuries. Between 1999 and 2002, the guilder was officially a "national subunit" of the euro. However, physical payments could only be made in guilders, as no euro coins or banknotes were available. The exact exchange rate, still relevant for old contracts and for exchange of the old currency for euros at the central bank, is 2.20371 Dutch guilders for 1 euro. Inverted, this gives 0.453780 euros for 1 guilder. Derived from the Dutch guilder are the Netherlands Antillean guilder (still in use in Curaçao and Sint Maarten) and the Surinamese gu ...

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 1851
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 ...

National Mills Day
National Mills Day is an event in the United Kingdom. It occurs annually on the second Sunday in May. It started off as a single day event, but expanded to include Saturday as well as Sunday, and is now promoted as National Mills Weekend. The event is coordinated by the Wind and Watermills section of the Society for the Protection of Ancient Buildings. Traditionally, many preserved wind and watermills that are usually closed to the general public open their doors and offer an insight into the mill workings and history. In support of National Mills Day, Denby Dale Radio Club coordinates hundreds of amateur radio stations who operate from alongside and sometimes inside the mills. Similar events Elsewhere in Europe, similar events are held in Germany, the Netherlands, Switzerland and other countries. Germany has the ''Deutscher Mühlentag'' on Whit Monday Whit Monday or Pentecost Monday, also known as Monday of the Holy Spirit, is the holiday celebrated the day after Pentecos ...

Steel
Steel is an alloy made up of iron with added carbon to improve its strength and fracture resistance compared to other forms of iron. Many other elements may be present or added. Stainless steels that are corrosion- and oxidation-resistant typically need an additional 11% chromium. Because of its high tensile strength and low cost, steel is used in buildings, infrastructure, tools, ships, trains, cars, machines, electrical appliances, weapons, and rockets. Iron is the base metal of steel. Depending on the temperature, it can take two crystalline forms (allotropic forms): body-centred cubic and face-centred cubic. The interaction of the allotropes of iron with the alloying elements, primarily carbon, gives steel and cast iron their range of unique properties. In pure iron, the crystal structure has relatively little resistance to the iron atoms slipping past one another, and so pure iron is quite ductile, or soft and easily formed. In steel, small amounts of carb ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
De Hollandsche Molen
Vereniging De Hollandsche Molen () ( en, Dutch Windmill Association) is a Dutch organization founded in 1923 to preserve windmills in the Netherlands, to document them, and to restore them. Financial support comes from members and from grants by organizations such as the (a Dutch lottery). Their website provides access to a database which documents some 1400 mills in the Netherlands; "Het Nederlands Molenbestand" is authoritative on the topic. The organization is often given credit for organizing a powerful and effective lobby aimed at procuring money from Dutch government institutions to fund restoration projects. Its former president Frederik Stokhuyzen was one of the foremost scholars on Dutch windmills; a recently revised edition of his 1961 book ''Molens'' is still the standard book on the topic. In 1981, Prince Claus of the Netherlands became the organization's patron, and attended ten ceremonies at which windmills were reopened; at his death in 2002 the 12 windmills owned ...

Stichting De Fryske Mole
The Stichting De Fryske Mole ( en, Frisian Mills Foundation) is a foundation for the preservation of windmills in the Dutch province Friesland, owning 42 of the 124 windmills in Friesland and closely co-operating with the Gild Fryske Mounders with which it publishes a quarterly magazine, ''De Utskoat''. The ''Stichting De Fryske Mole'' was founded in December 1970 to preserve those mills that were otherwise difficult to save. Consequently, all of the foundation's mills are drainage mills often standing in remote locations where there are no other parties interested in or able to pay for restoration and maintenance.

Windmill Sail
Windmills are powered by their sails. Sails are found in different designs, from primitive common sails to the advanced patent sails. Jib sails The jib sail is found in Mediterranean countries and consists of a simple triangle of cloth wound round a spar. The mill must be stopped in order to adjust the reefing of the sail. Though rare in the UK, at least two windmills are known to have had jib sails (St Mary's, Isle of Scilly and Cann Mills, Melbury Abbas).

In medieval mills, the sailcloth was wound in and out of a ladder-type arrangement of sails. Medieval sails could be constructed with or without outer sailbars. Post-medieval mill sails have a lattice framework over which the sailcloth is spread. There are vario ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
