Spinnenkop Openluchtmuseum, Arnhem
The spinnenkop of the Netherlands Open Air Museum in Arnhem is a small drainage mill originally located near Gorredijk, Friesland, Netherlands. It is a hollow post windmill that has been restored to working order. History The mill was built around 1800 and later moved to Gorredijk. Next to draining the polder it got a secondary use from 1886 onwards to inundate the local ice skating ring. It was named ''Molen van Posthuman'' after its owner or named after the polder it drained called ''Mountsjelân'' (English: little mill land). In 1922 it became superfluous when a kerosene-engine powered pumping station was built. The mill was then dismantled and given to the Dutch Open Air Museum where it was rebuilt in 1925. Description The ''spinnenkop'' (English: spiderhead mill) of the Netherlands Open Air Museum is a small hollow post mill winded by a winch. The mill has common sails. The wooden stocks have a span of and and are carried on a wooden ''windshaft''. The ''brake wheel'' ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
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] |
Het Fortuyn, Arnhem
Het Fortuyn ( en, The Fortune) is a tower mill in the Netherlands Open Air Museum, located in Arnhem, Gelderland, Netherlands which was built in 1920 and is in working order. History ''Het Fortuyn'' was originally built at Delft, South Holland in 1696. The first mill on that site was a post mill built in 1551 and demolished during the Eighty Years' War. Permission was granted in 1603 for a replacement mill to be erected. This was also a post mill, known as the ''Slikmolen''. It is shown in the painting ''Gezicht op Delft gezien vanuit het noorden'' by Hendrik Cornelisz Vroom. The painting is in the Museum Het Prinsenhof, Delft. ''Het Fortuyn'' was thus the third mill on this site. Circa 1800, the mill was still known as the ''Slikmolen'', gaining the name ''Het Fortuyn'' between 1807 and 1817. The mill drove four pairs of millstones. In 1873, a pair of millstones for the production of pearl barley was added. In the late 19th century the mill was owned by the Rossum family ...

Windmills In Gelderland
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 ...

Arnhem Smock Mill (1960)
The smock mill at the Netherlands Open Air Museum, Arnhem, Gelderland, Netherlands was originally built at Noordlaren, Groningen, Netherlands in 1862. It was dismantled in 1953 and re-erected at the museum in 1960. The mill has been restored to working order. History The mill was originally built to drain the Oosterpolder at Noordlaren, Groningen in 1862, replacing an earlier mill. In 1895, the upper part of the wooden upright shaft was replaced by one of cast iron, made by the IJzergieterij De Prins van Oranje, The Hague, South Holland. At that time, one pair of Common sails were replaced by Patent sails. Later, the mill ran with four Patent sails. In 1913, a steam-powered pumping station was constructed to assist the drainage of the polder during periods of calm. Electricity replaced steam in 1939. In 1942, it was proposed to demolish the mill, but this was postponed due to World War II. Post-war, the polder board and the Gemeente Haren disagreed over the proposal to demolis ...

Mijn Genoegen, Arnhem
Mijn Genoegen ( en, My Pleasure) is a paltrok mill in the Netherlands Open Air Museum in Arnhem, Gelderland, Netherlands which has been restored to working order. As are all Dutch ''paltrok mills,'' it is a wind-powered sawmill. History The windmill was built around 1680 in Dordrecht, where it was known as ''Het Spinnewiel'' ( en, The spinning-wheel). In 1854 the mill was moved to Numansdorp and the name was changed to ''Mijn Genoegen'' ( en, My pleasure). Two of the three wooden sawing frames were replaced by cast iron frames in 1854; the wooden windshaft was replaced with cast iron in 1887.

Huizermolen, Arnhem
Huizermolen is a post mill in the Netherlands Open Air Museum, Arnhem, Netherlands which was built in 1919 and is in working order. History The ''Huizermolen'' was built c. 1665 at Huizen. It had a single storey roundhouse there. A beam in the mill bore the date 1758. The mill was dismantled in 1916 and re-erected at the Netherlands Open Air Museum, Arnhem in 1919. It was one of the first buildings to be re-erected at the museum. The mill had a roundhouse at this time.

Archimedes' Screw
The Archimedes screw, also known as the Archimedean screw, hydrodynamic screw, water screw or Egyptian screw, is one of the earliest hydraulic machines. Using Archimedes screws as water pumps (Archimedes screw pump (ASP) or screw pump) dates back many centuries. As a machine used for transferring water from a low-lying body of water into irrigation ditches, water is pumped by turning a screw-shaped surface inside a pipe. In the modern world, Archimedes screw pumps are widely used in wastewater treatment plants and for dewatering low-lying regions. Archimedes Screws Turbines (ASTs) are a new form of small hydroelectric powerplant that can be applied even in low head sites. Archimedes screw generators operate in a wide range of flows (0.01 m^3/s to 14.5 m^3/s) and heads (0.1 m to 10 m), including low heads and moderate flow rates that is not ideal for traditional turbines and not occupied by high performance technologies. The Archimedes screw is a reversible hydraulic machine, a ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
De Kroon, Arnhem
De Kroon ( en, The Crown) or the Klarendalse Molen is a tower mill in Arnhem, Gelderland, Netherlands which was built in 1870 and is in working order. The mill is listed as a Rijksmonument. History ''De Kroon'' was originally built in 1849 for Albertus Burgers. It stood at the junction of Amsterdamseweg and Rozenstraat, where it was known as ''De Hoop'' ( en, The Hope). The mill was demolished in 1870 and rebuilt in the Klarendseweg. Burgers owned the mill until 1886. The ''Menno van Coehoornkazerne'' (an army barracks) was built nearby in 1885 and provided good trade for the mill. The barracks started grinding its own meal in 1900 and the mill's business declined. The mill was now owned by the Reymes brothers. The stage collapsed on 13 July 1933, but it was soon replaced. The mill was restored in 1936, but still ran at a loss. In 1945 the sails were fitted with the Fok system on their leading edges. The mill did little work due to competition from power-driven mills.
