Toll Island
In the United Kingdom a toll point or toll island is a place on a canal where a fee was collected as boats carrying cargo passed. These were sited at strategic points such as the stop lock at the transition from one canal company to another where water transfer was a concern, or at busy locks where water usage and pumping costs were an issue. Generally this was at a lock or an artificially constricted part of the canal so that the boat had to pass within inches of the toll point unable to evade the toll. On canals where the fee was based on cargo weight it also put the boat in a convenient place to read the gauging mark height from the water line. On busy canals which were built with a towpath on either side such as the Birmingham Canal Navigations BCN New Main Line the toll house may have been built on an island between two constricted channels so that one toll point could collect from boats travelling in each direction. The BCN retains several of these islands, for example at ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Octagonal BCN Canal Toll House At Smethwick Top Lock
In geometry, an octagon (from the Greek ὀκτάγωνον ''oktágōnon'', "eight angles") is an eight-sided polygon or 8-gon. A '' regular octagon'' has Schläfli symbol and can also be constructed as a quasiregular truncated square, t, which alternates two types of edges. A truncated octagon, t is a hexadecagon, . A 3D analog of the octagon can be the rhombicuboctahedron with the triangular faces on it like the replaced edges, if one considers the octagon to be a truncated square. Properties of the general octagon The sum of all the internal angles of any octagon is 1080°. As with all polygons, the external angles total 360°. If squares are constructed all internally or all externally on the sides of an octagon, then the midpoints of the segments connecting the centers of opposite squares form a quadrilateral that is both equidiagonal and orthodiagonal (that is, whose diagonals are equal in length and at right angles to each other).Dao Thanh Oai (2015), "Equilateral ...

Gunwale
The gunwale () is the top edge of the hull of a ship or boat. Originally the structure was the "gun wale" on a sailing warship, a horizontal reinforcing band added at and above the level of a gun deck to offset the stresses created by firing artillery. Over time it remained as a valuable stiffener mounted inboard of the sheer strake on commercial and recreational craft. In modern boats, it is the top edge of the hull where there is usually some form of stiffening, often in the form of traditional wooden boat construction members called the "inwale" and "outwale". On a canoe, the gunwale is typically the widened edge at the top of its hull, reinforced with wood, plastic Plastics are a wide range of synthetic or semi-synthetic materials that use polymers as a main ingredient.

Water Transport Infrastructure
Marine architecture is the design of architectural and engineering structures which support coastal design, near-shore and off-shore or deep-water planning for many projects such as shipyards, ship transport, coastal management or other marine and/or hydroscape activities. These structures include harbors, lighthouses, marinas, oil platforms, offshore drillings, accommodation platforms and offshore wind farms, floating engineering structures and building architectures or civil seascape developments. Floating structures in deep water may use suction caisson for anchoring.A History of Naval Architecture, By John Fincham See also *, a temporary water-excluding structure built in place, sometimes surrounding a working area as does an open caisson. * * * * * * * * * * * * * * * * * Photo gallery File:VolturnUS 1-8 in Castine ME.jpg, University of Maine's Floating wind turbine VolturnUS 1:8 was the first grid-connected offshore wind turbine in the Americas.

History Of The British Canal System
History (derived ) is the systematic study and the documentation of the human activity. The time period of event before the invention of writing systems is considered prehistory. "History" is an umbrella term comprising past events as well as the memory, discovery, collection, organization, presentation, and interpretation of these events. Historians seek knowledge of the past using historical sources such as written documents, oral accounts, art and material artifacts, and ecological markers. History is not complete and still has debatable mysteries. History is also an academic discipline which uses narrative to describe, examine, question, and analyze past events, and investigate their patterns of cause and effect. Historians often debate which narrative best explains an event, as well as the significance of different causes and effects. Historians also debate the nature of history as an end in itself, as well as its usefulness to give perspective on the problems of the ...

Canals Of The United Kingdom
The canals of the United Kingdom are a major part of the network of inland waterways in the United Kingdom. They have a varied history, from use for irrigation and transport, through becoming the focus of the Industrial Revolution, to today's role of recreational boating. Despite a period of abandonment, today the canal system in the United Kingdom is again increasing in use, with abandoned and derelict canals being reopened, and the construction of some new routes. Canals in England and Wales are maintained by navigation authorities. The biggest navigation authorities are the Canal & River Trust and the Environment Agency, but other canals are managed by companies, local authorities or charitable trusts. The majority of canals in the United Kingdom can accommodate boats with a length of between and are now used primarily for leisure. There are a number of canals which are far larger than this, including New Junction Canal and the Gloucester and Sharpness Canal, which can ...

River Weaver
The River Weaver is a river, navigable in its lower reaches, running in a curving route anti-clockwise across west Cheshire, northern England. Improvements to the river to make it navigable were authorised in 1720 and the work, which included eleven locks, was completed in 1732. An unusual clause in the enabling Act of Parliament stipulated that profits should be given to the County of Cheshire for the improvement of roads and bridges, but the navigation was not initially profitable, and it was 1775 before the first payments were made. Trade continued to rise, and by 1845, over £500,000 had been given to the county. The major trade was salt. The arrival of the Trent and Mersey Canal at Anderton in 1773 was detrimental to the salt trade at first, but ultimately beneficial, as salt was tipped down chutes from the canal into barges on the river navigation. Access to the river was improved in 1810 by the Weston Canal, which provided a link to Weston Point, where boats could rea ...

Trent And Mersey Canal
The Trent and Mersey Canal is a canal in Derbyshire, Staffordshire and Cheshire in north-central England. It is a "narrow canal" for the vast majority of its length, but at the extremities to the east of Burton upon Trent and north of Middlewich, it is a wide canal. The narrow locks and bridges are big enough for a single narrowboat wide by long, while the wide locks can accommodate boats wide, or two narrowboats next to each other. History The Trent and Mersey Canal (T&M) was built to link the River Trent at Derwent Mouth in Derbyshire to the River Mersey, and thereby provide an inland route between the major ports of Hull and Liverpool. The Mersey connection is made via the Bridgewater Canal, which it joins at Preston Brook in Cheshire. Although mileposts measure the distance to Preston Brook and Shardlow, Derwent Mouth is about beyond Shardlow. The plan of a canal connection from the Mersey to the Trent ("The Grand Trunk") came from canal engineer Jame ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Etruria, Staffordshire
Etruria is a suburb of Stoke-on-Trent, Staffordshire, England. History Home of Wedgwood Etruria was the fourth and penultimate site for the Wedgwood pottery business. Josiah Wedgwood, who was previously based in Burslem, opened his new works in 1769. It was named after the Italian district of Etruria, home of the Etruscan people who were renowned for their artistic products. The site covered and was next to the Trent and Mersey Canal. As well as Wedgwood's home, Etruria Hall, it included the Etruria Works which remained in use by the Wedgwood enterprise until 1950. The Wedgwood factory is now in Barlaston, a village about six miles to the south of the Etruria site. Etruria Hall was the site of the substantial invention of photography by Thomas Wedgwood in the 1790s. After Wedgwood Much of Etruria became derelict with the move of Wedgwood after the Second World War and the subsequent closure of the nearby Shelton Bar steelworks.

Boat Gauging House, Tipton
The Boat Gauging House is a building in Tipton, West Midlands, England. It is situated by the Main Line of the Birmingham Canal Navigations, and was used for calibrating new canal boats in order later to ascertain the weight of cargo carried. It is a Grade II listed building. Background Canal companies charged boats for using the canals, the fees, based on the weight of the cargo, being collected at toll points. In order to assess the weight of cargo, boats were initially calibrated. The "wet" method was done during the building of the boat; the Birmingham Canal Navigations (BCN) used the "dry" method, in which a new or refitted boat was loaded from empty with ton weights, and the resulting freeboard, or "dry inches", as the boat sat lower in the water, was each time noted. Gauging plates were then fixed to the boat."Gauging on the BCN" '' |
Engine Arm Aqueduct
The Engine Arm Aqueduct near Smethwick, West Midlands, England, was built in 1825 by Thomas Telford to carry a water feeder, the Engine Arm, from Edgbaston Reservoir over the BCN New Main Line canal to the adjacent and parallel Old Main Line. It is a Scheduled Ancient Monument and is Grade II* listed. It is a span structure consisting of a cast-iron trough supported by a single arch with five ribs, each consisting of four sections with bolted joints. The trough is supported on three of the ribs, with the adjacent towpaths being supported by cast-iron arcades of Gothic-styled arches and columns. All cast-iron features were manufactured at the Horseley Ironworks in nearby Tipton. The waterway in the aqueduct is wide with the towpaths either side being in width each. The eastern towpath is paved in brick with raised strips for horses.''Civil Engineering Heritage: Wales and West Central England, (2nd Ed.)'', Roger Cragg, 1997, Thomas Telford () Image:Engine Arm Aqueduct chan ...

BCN Main Line
The BCN Main Line, or Birmingham Canal Navigations Main Line is the evolving route of the Birmingham Canal between Birmingham and Wolverhampton in England. The name ''Main Line'' was used to distinguish the main Birmingham to Wolverhampton route from the many other canals and branches built or acquired by the Birmingham Canal Navigations company. BCN Old Main Line On 24 January 1767 a number of prominent Birmingham businessmen, including Matthew Boulton and others from the Lunar Society, held a public meeting in the White Swan, High Street, Birmingham''Smethwick and the BCN'', Malcolm D. Freeman, 2003, Sandwell MBC and Smethwick Heritage Centre Trust to consider the possibility of building a canal from Birmingham to the Staffordshire and Worcestershire Canal near Wolverhampton, taking in the coalfields of the Black Country. They commissioned the canal engineer James Brindley to propose a route. Brindley came back with a largely level but meandering route via Smethwick, O ...
