Horse Capstan
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. The gin wheel at Nottingham Industrial Museum dating from 1844, is a wooden drum, set on a vertical pole within a wooden frame, with a horizonta ...

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. 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 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 weight by a given force" as the lever, windlass, screw for power, wedge, and tackle block (pulley). Until nearly the end of the nine ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Waterwheel
A water wheel is a machine for converting the energy of flowing or falling water into useful forms of power, often in a watermill. A water wheel consists of a wheel (usually constructed from wood or metal), with a number of blades or buckets arranged on the outside rim forming the driving car. Water wheels were still in commercial use well into the 20th century but they are no longer in common use. Uses included 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. Waterwheels were used for various purposes from ag ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Steam Engine
A steam engine is a heat engine that performs 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. This pushing force can be transformed, by a connecting rod and crank, into rotational force for work. The term "steam engine" is generally applied only to reciprocating engines as just described, not to the steam turbine. Steam engines 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 boilers etc.), such as railway steam locomotives and portable engines, or may refer to the piston or turbine machinery alone, as in the beam engine and stationary steam engine. Although steam-driven devices were known as early as the aeolipile in the f ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
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 Watt steam engine, 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 stamp mill, ore stamping machinery. Background: The steam engine in Cornwall Cornwall has long had tin, copper and other metal ore mines, but if mining is to take place at greater depths, a means to dewatering, dewater the mine must be found. Lifting the weight of water up from the depths requires great amounts of work (physics), 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 c ...

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 ho ...

Pinxton
Pinxton is a village and civil parish in Derbyshire on the eastern 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 2011 Census had a population of 5,699. "Pinxton CCTV level crossing", located on the up and down Kirkby lines, is a major tourist attraction for train enthusiasts who come from all over the country to take photographs of some of the unique locomotives that pass over the crossing. 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, along with a number of other manors, 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" ...

Lydney
Lydney is a town and 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 bypassed by the A48 road since 1995. The population was about 8,960 in the 2001 census, reducing to 8,766 at the 2011 census. 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 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, alternative 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 Domesday Book.
