Whim (mining)
A whim, also called a whim gin or a horse capstan, is a device similar to a windlass which is used in mining for hauling materials to the surface. It comprises a capstan or a wide drum with a vertical axle. A rope is wound around the drum, with both ends traversing several pulleys and hanging down the mine shaft. As the drum is turned around, one end of the rope is lowered, carrying an empty bucket, while the other one is raised, carrying a full load. The major benefit of a whim is that its operation can be performed at a distance from the shaft, thus resolving some of the congestion. Early whims were horse-powered, but later they were powered by waterwheels or steam engines, including the most advanced Cornish engines. Whims were used in coal mines until the end of the nineteenth century. Horse whims were also used to power team boats.

Windlass
The windlass is an apparatus for moving heavy weights. Typically, a windlass consists of a horizontal cylinder (barrel), which is rotated by the turn of a crank or belt. A winch is affixed to one or both ends, and a cable or rope is wound around the winch, pulling a weight attached to the opposite end. The Greek scientist Archimedes was the inventor of the windlass. A surviving medieval windlass, dated to –1400, is in the Church of St Mary and All Saints, Chesterfield. The oldest depiction of a windlass for raising water can be found in the Book of Agriculture published in 1313 by the Chinese official Wang Zhen (inventor), Wang Zhen of the Yuan Dynasty ( 1290–1333). Uses * Vitruvius, a military engineer writing about 28 BC, defined a machine as "a combination of timber fastened together, chiefly efficacious in moving great weights". About a century later, Hero of Alexandria summarized the practice of his day by naming the "five simple machines" for "moving a given ...

Waterwheel
A water wheel is a machine for converting the kinetic energy of flowing or falling water into useful forms of power, often in a watermill. A water wheel consists of a large wheel (usually constructed from wood or metal), with numerous blades or buckets attached to the outer rim forming the drive mechanism. Water wheels were still in commercial use well into the 20th century, although they are no longer in common use today. Water wheels are used for milling flour in gristmills, grinding wood into pulp for papermaking, hammering wrought iron, machining, ore crushing and pounding fibre for use in the manufacture of cloth. Some water wheels are fed by water from a mill pond, which is formed when a flowing stream is dammed. A channel for the water flowing to or from a water wheel is called a mill race. The race bringing water from the mill pond to the water wheel is a headrace; the one carrying water after it has left the wheel is commonly referred to as a tailrace. Waterwheel ...

Steam Engine
A steam engine is a heat engine that performs Work (physics), 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 (locomotive), cylinder. This pushing force can be transformed by a connecting rod and Crank (mechanism), crank into rotational force for work. The term "steam engine" is most commonly applied to reciprocating engines as just described, although some authorities have also referred to the steam turbine and devices such as Hero's aeolipile as "steam engines". The essential feature of steam engines is that they 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 Boiler (power generation), boilers etc.), such as railway steam locomot ...

Cornish Engine
A Cornish engine is a type of steam engine developed in Cornwall, England, mainly for pumping water from a mine. It is a form of beam engine that uses steam at a higher pressure than the earlier engines designed by James Watt. The engines were also used for powering man engines to assist the underground miners' journeys to and from their working levels, for winching materials into and out of the mine, and for powering on-site ore stamping machinery. Background Cornwall has long had tin, copper and other metal ore mines, but if mining is to take place at greater depths, a means to dewater the mine must be found. Lifting the weight of water up from the depths requires great amounts of work input. This energy may be weakly supplied by horse power or a waterwheel to operate pumps, but horses have limited power and waterwheels need a suitable stream of water. Accordingly, the innovation of coal-fired steam power to work pumps was more versatile and effective to the mining ind ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Team Boat
A team boat, horse boat, or horse ferry, is a watercraft powered by horses or mules, generally using a treadmill, which serves as a horse engine. Team boats were popular as ferries in the United States from the mid-1810s to the 1850s. Types The first documented horse-powered boat in the United States was built on the Delaware River in 1791 by John Fitch. There are three types of team boats. In one, four or five horses are placed in each side of the boat in a circular treadwheel, and the paddle wheels, arranged like the side wheel steamboat of later days were turned by means of cogs and gearing connected with other cogs on the shaft of the paddle wheels. The horses were hitched to strong timbers and by a forward movement of the feet caused the treadwheel upon which they stood to revolve and thus operate the gear wheels. Another type of team boat uses a "horse whim," a type of horse mill. It has a large revolving wheel in the middle, and a center post known as a "whim" (or ...

Nottingham Industrial Museum
The Nottingham Industrial Museum is a volunteer-run museum situated in part of the 17th-century stables block of Wollaton Hall, located in a suburb of the city of Nottingham. The museum won the ''Nottinghamshire Heritage Site of the Year Award 2012'', a local accolade issued by Experience Nottinghamshire. The Museum collection closed in 2009 after Nottingham City Council withdrew funding, but has since reopened at weekends and bank holidays, helped by a £91,000 government grant, and run by volunteers. The museum contains a display of local textiles machinery, transport, telecommunications, mining and engineering technology. There is a display of cycles, motorcycles, and motor cars. There are examples of significant lace-making machinery. It also houses an operational beam engine, from the Basford, Nottingham pumping station. Context Nottingham, ''Tiggua Cobaucc'' ─ Place of Caves, ''Snotengaham'' ─ "the homestead of Snot's people" was settled by the Vikings in 867 and by ...

Pinxton
Pinxton is a village and civil parish in Derbyshire on the western boundary of Nottinghamshire, England, just south of the Pinxton Interchange at Junction 28 of the M1 motorway where the A38 road meets the M1. Pinxton is part of the Bolsover District and at the 2021 Census had a population of 5,652. History Etymology In Anglo-Saxon times, Pinxton was a small agricultural community, thought to have been recorded in the Domesday Book of 1086 as "Esnotrewic." It is also thought that it was known as "Snodeswic," given by Wulfric Spott to Burton Abbey. In Norman times, it was under the control of William Peveril, for whom it was held by Drogo fitz Pons. It is thought that he renamed the manor "Ponceston" and it gradually changed to Penekeston and then to Pinxton. Coal Since 1800 BC, coal had been extracted in the area. In 1794 the Cromford Canal encouraged this trade. By the beginning of the next century there were a number of deep coal mines. Trade increased with the growth ...

Lydney
Lydney is a town and civil parishes in England, civil parish in Gloucestershire, England. It is on the west bank of the River Severn in the Forest of Dean District, and is 16 miles (25 km) southwest of Gloucester. The town has been Bypass (road), bypassed by the A48 road since 1995. The population was 8,960 at the 2001 census, decreasing to 8,766 at the 2011 census, and increasing to 10,043 at the 2021 census. Lydney has a harbour on the Severn, created when the Lydney Canal was built. Adjoining the town, Lydney Park gardens have a Roman Britain, Roman temple dedicated to Nodens. Etymology According to Cook (1906) the toponym "Lydney" derives from the Old English *''Lydan-eġ'', "Lludd's Island", which could connect it with the name Nudd/Nodens. However, more probable etymologies of Lydney are offered in other sources. A. D. Mills suggests "island or river-meadow of the sailor, or of a man named *Lida", citing the forms "Lideneg" from c. 853 and "Ledenei" from the 1086 Dom ...
