Blondin (quarry Equipment)
Blondins (also known as Henderson Inclined Cableways) were a type of material ropeway; they were named after the famous tightrope walker Charles Blondin. Description Blondins are a specialized type of material ropeway that incorporates a mechanism to raise and lower loads vertically from the suspended ropeway. This allowed them to cross wide, deep spaces such as quarries and move material from the floor up to the level of the ropeway and across to the edge of the quarry. They are powered either by a steam or electrical hoist. History Blondins were developed by John Fyfe, a Scottish quarry engineer. He installed the first example in 1872 at Kemnay granite quarry at Garioch. In 1896, John M. Henderson and Co. introduced the first commercially available Blondin system, which used steel ropes instead of the earlier iron ropes. The first installation at a Welsh slate quarry was a pair of blondins at Pen-yr-Orsedd quarry in 1899. These were powered by stationary steam engines ...

Blondin Ropeway - Geograph
Charles Blondin (born Jean François Gravelet, 28 February 182422 February 1897) was a French tightrope walker and acrobat. He toured the United States and was known for crossing the Niagara Gorge on a tightrope. During an event in Dublin in 1860, the rope on which he was walking broke and two workers were killed, although Blondin was not injured. He married three times and had eight children. His name became synonymous with tightrope walking. Early life Blondin was born on 28 February 1824 in Hesdin, Pas-de-Calais, France.''Irish Times'', Dublin, 25 May 1861 His birth name was Jean-François Gravelet, though he was known by many other names and nicknames: Charles Blondin, Jean-François Blondin, Chevalier Blondin, and The Great Blondin. At the age of five, he was sent to the École de Gymnase in Lyon and, after six months of training as an acrobat, made his first public appearance as "The Boy Wonder". His superior skill and grace, as well as the originality of the settings ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Pen-yr-Orsedd Quarry
Pen-yr-Orsedd quarry was a slate quarry in the Nantlle Valley in North Wales. It was one of the last slate quarries operating in North Wales and the last operating in the Nantlle Valley area, finally closing in 1979. History Pen-yr-Orsedd opened in 1816, owned by William Turner who was also the owner of the nearby Dorothea quarry and the Diphwys Casson quarry in Blaenau Ffestiniog. It was acquired on 1854 by John Lloyd Jones who sold it on to the Darbishire Company, owners of the Penmaenmawr granite quarries, in 1862. The new owners invested £20,000 () to expand the quarry, though with limited results; by 1871 the quarry was producing just 500 tons per year. William Darbishire took over direct management of the quarry that year and by 1882 had raised production to almost 8,000 tons. Pen-yr-Orsedd was one of the major slate producers of the Nantlle Valley. It was the last of the Nantlle quarries to commercially produce slate, closing in 1979. Narrow-gauge railway museu ...

Narrow Gauge
A narrow-gauge railway (narrow-gauge railroad in the US) is a railway with a track gauge narrower than standard . Most narrow-gauge railways are between and . Since narrow-gauge railways are usually built with tighter curves, smaller structure gauges, and lighter rails, they can be less costly to build, equip, and operate than standard- or broad-gauge railways (particularly in mountainous or difficult terrain). Lower-cost narrow-gauge railways are often used in mountainous terrain, where engineering savings can be substantial. Lower-cost narrow-gauge railways are often built to serve industries as well as sparsely populated communities where the traffic potential would not justify the cost of a standard- or broad-gauge line. Narrow-gauge railways have specialised use in mines and other environments where a small structure gauge necessitates a small loading gauge. In some countries, narrow gauge is the standard; Japan, Indonesia, Taiwan, New Zealand, South Africa, and the Aust ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Bethesda, Gwynedd
Bethesda (; ) is a town and community on the River Ogwen and the A5 road on the edge of Snowdonia, in Gwynedd, north-west Wales. It is the fifth-largest community in Gwynedd. History The settlement's ancient name was Cilfoden, formerly known as Glanogwen. In 1823, the Bethesda Chapel was built and the town subsequently grew around and later named after it. The chapel was rebuilt in 1840. The town grew around the slate quarrying industries; the largest of the local quarries is the Penrhyn Quarry. At its peak, the town exported purple slate all over the world. Penrhyn Quarry suffered a three-year strike led by the North Wales Quarrymen's Union between 1900 and 1903 – the longest industrial dispute in British history. This led to the creation of the nearby village of Tregarth, built by the quarry owners, which housed the families of those workers who had not struck. It also led to the formation of three co-operative quarries, the largest of which Pantdreiniog dominated the t ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Penrhyn Quarry
The Penrhyn quarry is a slate quarry located near Bethesda, North Wales. At the end of the nineteenth century it was the world's largest slate quarry; the main pit is nearly long and deep, and it was worked by nearly 3,000 quarrymen. It has since been superseded in size by slate quarries in China, Spain and the USA. Penrhyn is still Britain's largest slate quarry but its workforce is now nearer 200. History The first reference to slate extraction at Penrhyn is from 1570, when the quarry is mentioned in a Welsh poem. The quarry was developed in the 1770s by Richard Pennant, later Baron Penrhyn. Much of his early working was for local use only as no large scale transport infrastructure was developed until Pennant's involvement. From then on, slates from the quarry were transported to the sea at Port Penrhyn on the narrow gauge Penrhyn Quarry Railway built in 1798, one of the earliest railway lines. In the 19th century the Penrhyn Quarry, along with the Dinorwic quarry, dom ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Stationary Steam Engine
Stationary steam engines are fixed steam engines used for pumping or driving mills and factories, and for power generation. They are distinct from locomotive engines used on railways, traction engines for heavy steam haulage on roads, steam cars (and other motor vehicles), agricultural engines used for ploughing or threshing, marine engines, and the steam turbines used as the mechanism of power generation for most nuclear power plants. They were introduced during the 18th century and widely made for the whole of the 19th century and most of the first half of the 20th century, only declining as electricity supply and the internal combustion engine became more widespread. Types of stationary steam engine There are different patterns of stationary steam engines, distinguished by the layout of the cylinders and crankshaft: * Beam engines have a rocking beam providing the connection between the vertical cylinder and crankshaft. *Table engines have the crosshead above the vert ...

Slate Industry In Wales
The existence of a slate industry in Wales is attested since the Roman period, when slate was used to roof the fort at Segontium, now Caernarfon. The slate industry grew slowly until the early 18th century, then expanded rapidly until the late 19th century, at which time the most important slate producing areas were in northwest Wales, including the Penrhyn Quarry near Bethesda, the Dinorwic Quarry near Llanberis, the Nantlle Valley quarries, and Blaenau Ffestiniog, where the slate was mined rather than quarried. Penrhyn and Dinorwig were the two largest slate quarries in the world, and the Oakeley mine at Blaenau Ffestiniog was the largest slate mine in the world. Slate is mainly used for roofing, but is also produced as thicker slab for a variety of uses including flooring, worktops and headstones.Lindsay p. 133 Up to the end of the 18th century, slate was extracted on a small scale by groups of quarrymen who paid a royalty to the landlord, carted slate to the ports, and ...

Garioch
Garioch ( sco, The Geerie, , gd, Gairbheach) is one of six committee areas in Aberdeenshire, Scotland. It has a population of 46,254 (2006 estimate), which gives it the largest population of Aberdeenshire's six committee areas. The Garioch consists primarily of the district drained by the River Ury and its tributaries the Shevock and the Gadie Burn. Name The placename "Garioch" comes from the Gaelic ''Gairbheach'', meaning "place of roughness". The name is first mentioned as "Garviach" in a charter dated to between 1178 and 1182, referring at that time to the small area now known as the Upper Garioch. This is still the meaning used in a charter granting land to the Bishop of Aberdeen in 1190, but by 1195 the name was being used to describe the entire area of the provincial lordship, extending as far east as Inverurie. History Before the late 12th century, Garioch consisted only of the area of the parishes of Culsalmond, Insch, Rathmuriel, Kennethmont, Leslie, Premnay and C ...
