Tintagel Slate Quarries
Tintagel Slate Quarries fall into two categories: the series of quarries lying between Tintagel Castle and Trebarwith Strand on the north coast of Cornwall, South West England and the open cast quarries further inland. There are around eight cliff-edge quarries as well as two wharfs, all of which are now disused as well as four inland sites, two of which are still in operation. The first quarry to be worked appears to have been Lanterdan at some point in the fifteenth century, while the last of the coastal quarries, Long Grass ceased operations in 1937. The remains of the coastal quarries occupy coastal land owned by the National Trust and most are easily accessible from the South West Coast Path. The Prince of Wales Quarry has been turned into a country park by North Cornwall District Council.

Beam Engine
A beam engine is a type of steam engine where a pivoted overhead beam is used to apply the force from a vertical piston to a vertical connecting rod. This configuration, with the engine directly driving a pump, was first used by Thomas Newcomen around 1705 to remove water from mines in Cornwall. The efficiency of the engines was improved by engineers including James Watt, who added a separate condenser; Jonathan Hornblower and Arthur Woolf, who compounded the cylinders; and William McNaught, who devised a method of compounding an existing engine. Beam engines were first used to pump water out of mines or into canals but could be used to pump water to supplement the flow for a waterwheel powering a mill. The rotative beam engine is a later design of beam engine where the connecting rod drives a flywheel by means of a crank (or, historically, by means of a sun and planet gear). These beam engines could be used to directly power the line-shafting in a mill. They als ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Arthur Woolf
Arthur Woolf (1766, Camborne, Cornwall – 16 October 1837, Guernsey) was a Cornish engineer, most famous for inventing a high-pressure compound steam engine. As such he made an outstanding contribution to the development and perfection of the Cornish engine. Woolf left Cornwall in 1785 to work for Joseph Bramah's engineering works in London. He worked there and at other firms as an engineer and engine builder until 1811 experimenting with high pressure steam and a much improved boiler. Whereupon he returned to Cornwall. Michael Loam, inventor of the man engine, was trained by him. When he returned to Cornwall, beam engine designs were crude, shackled by outdated Watt patents and poor engineering, struggling to compete with large water wheels, even used underground. He learned from Bramah that to move forward meant adopting much improved engineering techniques, for it was Bramah who invented quality control. Woolf was chief engineer to Harvey & Co of Hayle, the leading eng ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Hole Beach
Hole Beach is a bathing and surf beach just north of Trebarwith Strand on the North Coast of Cornwall, South West England. The beach can be accessed from Trebarwith at low tide or by a zigzagging quarryman's track from the village of Treknow. The beach is sandy and the water is good for surfing Surfing is a surface water sport in which an individual, a surfer (or two in tandem surfing), uses a board to ride on the forward section, or face, of a moving wave of water, which usually carries the surfer towards the shore. Waves suitabl .... The sheer cliffs to the north of the beach form part of the now disused Caroline Slate Quarry and were created by quarrymen suspended by ropes attached to strongpoints some 75m on the clifftop above.«Coastal Slate Quarries – Tintagel to Trebarwith” (1990) Adam Sharpe, CAU archaeological survey for the National Trust.

Youth Hostel
A hostel is a form of low-cost, short-term shared sociable lodging where guests can rent a bed, usually a bunk bed in a dormitory, with shared use of a lounge and sometimes a kitchen. Rooms can be mixed or single-sex and have private or shared bathrooms. Private rooms may also be available, but the property must offer dormitories to be considered a hostel. Hostels are popular forms of lodging for backpackers. They are part of the sharing economy. Benefits of hostels include lower costs and opportunities to meet people from different places, find travel partners, and share travel ideas. Some hostels, such as Zostel in India or Hostelling International, cater to a niche market of travelers. For example, one hostel might feature in-house social gatherings such as movie nights or communal dinners, another might feature local tours, one might be known for its parties, and another might have a quieter place to relax in serenity, or be located on the beach. Newer hostels focus on a ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Camelford Station
Slaughterbridge ( kw, Tre war Ponshal), Treague and Camelford Station ( kw, Gorsav Reskammel) are three adjoining settlements in north Cornwall, England. They straddle the boundary of Forrabury and Minster and Lanteglos by Camelford civil parishes just over a mile (2 km) north-west of the market town of Camelford. The settlements are on the B3314 road from the A39 to Delabole (now part of a busy route from the A30 near Launceston to north Cornwall).Ordnance Survey: Landranger map sheet 200 ''Newquay & Bodmin'' Description and history At Slaughterbridge the B3314 road drops dramatically into the valley of the River Camel, describing a steeply graded 'S' bend and narrowing over the eponymous single-track bridge over the river. Slaughterbridge takes its name from 'slohtre' the Old English word for 'marsh' rather than a reference to killing. There is no evidence for battles fought here (see Gafulford for details).

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. 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 horizont ...

Bedrock
In geology, bedrock is solid rock that lies under loose material ( regolith) within the crust of Earth or another terrestrial planet. Definition Bedrock is the solid rock that underlies looser surface material. An exposed portion of bedrock is often called an outcrop. The various kinds of broken and weathered rock material, such as soil and subsoil, that may overlie the bedrock are known as regolith. Engineering geology The surface of the bedrock beneath the soil cover (regolith) is also known as ''rockhead'' in engineering geology, and its identification by digging, drilling or geophysical methods is an important task in most civil engineering projects. Superficial deposits can be very thick, such that the bedrock lies hundreds of meters below the surface. Weathering of bedrock Exposed bedrock experiences weathering, which may be physical or chemical, and which alters the structure of the rock to leave it susceptible to erosion. Bedrock may also experience ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Upper Devonian
The Devonian ( ) is a geologic period and system of the Paleozoic era, spanning 60.3 million years from the end of the Silurian, million years ago (Mya), to the beginning of the Carboniferous, Mya. It is named after Devon, England, where rocks from this period were first studied. The first significant adaptive radiation of life on dry land occurred during the Devonian. Free-sporing vascular plants began to spread across dry land, forming extensive forests which covered the continents. By the middle of the Devonian, several groups of plants had evolved leaves and true roots, and by the end of the period the first seed-bearing plants appeared. The arthropod groups of myriapods, arachnids and hexapods also became well-established early in this period, after starting their expansion to land at least from the Ordovician period. Fish reached substantial diversity during this time, leading the Devonian to often be dubbed the Age of Fishes. The placoderms began dominating ...
