Cornish Engines Preservation Committee
The Trevithick Society is a registered charity named for Richard Trevithick, a Cornish engineer who contributed to the use of high pressure steam engines for transportation and mining applications. History In 1935 the Cornish Engines Preservation Committee (CEPC) was formed to rescue the Levant winding engine which was deemed outdated and scheduled to be scrapped. CEPC were forerunners in the field of Industrial Archaeology. They acquired another winding engine and two pumping engines. CEPC merged with the newly formed Cornish Waterwheel Preservation Society in 1971 and named the organisation the Trevithick Society after Richard Trevithick. Chapel Coombe At Chapel Coombe a set of old Cornish stamps has been re-erected by the Trevithick Society. Dolcoath pumping engine Dolcoath was the largest and deepest mine in Cornwall, with its principal shaft, known as New Sump Shaft, eventually reaching a depth of below the surface. The pumping engine that worked this shaft dated from ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Snaefell Wheel
The Snaefell Wheel (also known as Lady Evelyn) is a waterwheel in Laxey, Isle of Man. The wheel stands in the washing floors in Laxey Glen Gardens, approximately 700 metres south of the larger Laxey Wheel. The wheel was unveiled with the name ''Lady Evelyn'' to mark the extensive work of Evelyn Jones in her support of the Laxey Mines Research Team. History The wheel was purchased by the Snaefell Mining Company in 1865. Built by Messrs Leigh and Gilbert Howell of the Hawarden iron works in Flintshire, north Wales, it was one of two identical 50 ft (15.24 m) diameter wheels to be produced. By 1910, the wheel had come to the end of its working life at the Snaefell Mining Company and was disassembled to be sent to Bodmin, Cornwall. By the 1950s the wheel had fallen into disuse, and in 1971 the Cornish Wheel Preservation Society had acquired the wheel and dismantled it for preservation. The society later merged with the Trevithick Society The Trevithick Society i ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Dolcoath Mine
Dolcoath mine ( kw, Bal Dorkoth) was a copper and tin mine in Camborne, Cornwall, England, United Kingdom. Its name derives from the Cornish for 'Old Ground', and it was also affectionately known as ''The Queen of Cornish Mines''. The site is north-west of Carn Brea. Dolcoath Road runs between the A3047 road and Chapel Hill. The site is south of this road. History The mineral rights were owned by the Basset family of Tehidy who are recorded on a deed in 1588 as leasing the ground to a family called Crane. By 1720 the mine was being worked for copper, and it was almost deep in 1746, when William Borlase called it a "very considerable mine". In 1778 it was nearly deep, according to William Price. The mine closed in 1787 because the large amount of copper ore that was being cheaply mined from Parys Mountain on Anglesey had depressed the price. However the price of copper slowly recovered and the mine reopened in 1799. Of around 470 copper-producing mines in Cornwall and Devon, ...

Archaeological Organizations
Archaeology or archeology is the scientific study of human activity through the recovery and analysis of material culture. The archaeological record consists of Artifact (archaeology), artifacts, architecture, biofact (archaeology), biofacts or ecofacts, archaeological site, sites, and cultural landscapes. Archaeology can be considered both a social science and a branch of the humanities. It is usually considered an independent academic discipline, but may also be classified as part of anthropology (in North America – the four-field approach), history or geography. Archaeologists study human prehistory and history, from the development of the first stone tools at Lomekwi in East Africa 3.3 million years ago up until recent decades. Archaeology is distinct from palaeontology, which is the study of fossil remains. Archaeology is particularly important for learning about prehistoric societies, for which, by definition, there are no written records. Prehistory includes ove ...

Industrial Archaeology
Industrial archaeology (IA) is the systematic study of material evidence associated with the industrial past. This evidence, collectively referred to as industrial heritage, includes buildings, machinery, artifacts, sites, infrastructure, documents and other items associated with the production, manufacture, extraction, transport or construction of a product or range of products. The field of industrial archaeology incorporates a range of disciplines including archaeology, architecture, construction, engineering, historic preservation, museology, technology, urban planning and other specialties, in order to piece together the history of past industrial activities. The scientific interpretation of material evidence is often necessary, as the written record of many industrial techniques is often incomplete or nonexistent. Industrial archaeology includes both the examination of standing structures and sites that must be studied by an excavation. The field of industrial arch ...

Lean's Engine Reporter
''Lean's Engine Reporter'' was founded in 1810 to publicize the performances of different Cornish engines used for mine pumping in Cornwall. The first Reporter of Duty was Joel Lean. The ''Reporter'', published monthly, gave, for each engine and its pumps, the number of strokes (measured by a counter kept in a locked box), and the amount of coal used. From this, and sizes of the pumps, the engine duty was found: this was the number of pounds of water raised one foot by a bushel of coal. Between 1810 and 1840 this reporting, and competition between engineers, raised the duty from around 20 million to 90 million pounds, a much higher efficiency than found in engines elsewhere at the same time. The improvements were an increase in the steam pressure used, full expansion to low pressure, and insulation to avoid heat loss. The ''Reporter'' continued to be published by various members of Lean's family until 1904. This open competition between engineers has been suggestedFor example ...

Geevor Tin Mine
Geevor Tin Mine (from kw, Whel an Gever, meaning "mine of the goats"), formerly North Levant Mine is a tin mine in the far west of Cornwall, United Kingdom, between the villages of Pendeen and Trewellard. It was operational between 1911 and 1990 during which time it produced about 50,000 tons of black tin. It is now a museum and heritage centre left as a living history of a working tin mine. The museum is an Anchor Point of ERIH, The European Route of Industrial Heritage. Since 2006, the mine has been part of the UNESCO World Heritage Site Cornwall and West Devon Mining Landscape. History Tin and copper have been mined from the general area of Geevor since the late 18th century. It was originally a small enterprise known as ''Wheal an Giver'', "a piece of ground occupied by goats". The area was worked under the name of East Levant Mine until 1840 and then as North Levant from 1851 to 1891 when it closed.Stanier, 1998 p.53 During the 1880s as many as 176 workers were employed at ...

Cast Iron
Cast iron is a class of iron–carbon alloys with a carbon content more than 2%. Its usefulness derives from its relatively low melting temperature. The alloy constituents affect its color when fractured: white cast iron has carbide impurities which allow cracks to pass straight through, grey cast iron has graphite flakes which deflect a passing crack and initiate countless new cracks as the material breaks, and ductile cast iron has spherical graphite "nodules" which stop the crack from further progressing. Carbon (C), ranging from 1.8 to 4 wt%, and silicon (Si), 1–3 wt%, are the main alloying elements of cast iron. Iron alloys with lower carbon content are known as steel. Cast iron tends to be brittle, except for malleable cast irons. With its relatively low melting point, good fluidity, castability, excellent machinability, resistance to deformation and wear resistance, cast irons have become an engineering material with a wide range of applications and are ...

Stamp Mill
A stamp mill (or stamp battery or stamping mill) is a type of mill machine that crushes material by pounding rather than grinding, either for further processing or for extraction of metallic ores. Breaking material down is a type of unit operation. Description A stamp mill consists of a set of heavy steel (iron-shod wood in some cases) stamps, loosely held vertically in a frame, in which the stamps can slide up and down. They are lifted by cams on a horizontal rotating shaft. As the cam moves from under the stamp, the stamp falls onto the ore below, crushing the rock, and the lifting process is repeated at the next pass of the cam. Each one frame and stamp set is sometimes called a "battery" or, confusingly, a "stamp" and mills are sometimes categorised by how many stamps they have, i.e. a "10 stamp mill" has 10 sets. They usually are arranged linearly, but when a mill is enlarged, a new line of them may be constructed rather than extending the line. Abandoned mill sites (as ...
