Vertical Boiler
A vertical boiler is a type of fire-tube or water-tube boiler where the boiler barrel is oriented vertically instead of the more common horizontal orientation. Vertical boilers were used for a variety of steam-powered vehicles and other mobile machines, including early steam locomotives. Design considerations Tube arrangements Many different tube arrangements have been used. Examples include: ;Fire tubes * Vertical fire-tube boiler * Vertical boiler with horizontal fire-tubes ;Water tubes * Vertical cross-tube boiler * Field-tube boiler * Thimble tube boiler * Spiral watertube boiler Advantages The main advantages of a vertical boiler are: * Small footprint – where width and length constraints are critical, use of a vertical boiler permits design of a smaller machine. * Water-level tolerance – The water level in a horizontal boiler must be maintained above the crown (top) of the firebox at all times, or the crownplate could overheat and buckle, causing a boiler explosion. ...

Shrewsbury
Shrewsbury ( , also ) is a market town, civil parish, and the county town of Shropshire, England, on the River Severn, north-west of London; at the 2021 census, it had a population of 76,782. The town's name can be pronounced as either 'Shrowsbury' or 'Shroosbury', the correct pronunciation being a matter of longstanding debate. The town centre has a largely unspoilt medieval street plan and over 660 listed buildings, including several examples of timber framing from the 15th and 16th centuries. Shrewsbury Castle, a red sandstone fortification, and Shrewsbury Abbey, a former Benedictine monastery, were founded in 1074 and 1083 respectively by the Norman Earl of Shrewsbury, Roger de Montgomery. The town is the birthplace of Charles Darwin and is where he spent 27 years of his life. east of the Welsh border, Shrewsbury serves as the commercial centre for Shropshire and mid-Wales, with a retail output of over £299 million per year and light industry and distribution centre ...

Sentinel Waggon Works
Sentinel Waggon Works Ltd was a British company based in Shrewsbury, Shropshire that made steam-powered lorries (steam wagons), railway locomotives, and later, diesel engined lorries, buses and locomotives. History Alley & MacLellan, Sentinel Works, Jessie Street Glasgow Alley & MacLellan was founded in 1875 and was based in Polmadie, Glasgow. This company continued in operation until the 1950s. Initially manufacturing valves and compressors for steam engines, and later whole steamships, Alley & MacLellan acquired Simpson and Bibby of Horsehay, Shropshire, manufacturer of steam-powered road vehicles, in 1903. They began producing steam road vehicles in 1905 and in 1906 introduced a five-ton vertical-boiler steam wagon, which featured a two-cylinder undertype engine and chain drive. Around 1915, Alley & McLellan moved the steam wagon production to a new factory to Shrewsbury and it continued under a separate company (see below), and in 1918 the company also opened a th ...

Wales
Wales ( cy, Cymru ) is a Countries of the United Kingdom, country that is part of the United Kingdom. It is bordered by England to the Wales–England border, east, the Irish Sea to the north and west, the Celtic Sea to the south west and the Bristol Channel to the south. It had a population in 2021 of 3,107,500 and has a total area of . Wales has over of coastline and is largely mountainous with its higher peaks in the north and central areas, including Snowdon (), its highest summit. The country lies within the Temperateness, north temperate zone and has a changeable, maritime climate. The capital and largest city is Cardiff. Welsh national identity emerged among the Celtic Britons after the Roman withdrawal from Britain in the 5th century, and Wales was formed as a Kingdom of Wales, kingdom under Gruffydd ap Llywelyn in 1055. Wales is regarded as one of the Celtic nations. The Conquest of Wales by Edward I, conquest of Wales by Edward I of England was completed by 1283, th ...

Slate Industry
The slate industry is the industry related to the extraction and processing of slate. Slate is either quarried from a ''slate quarry'' or reached by tunneling in a ''slate mine''. Common uses for slate include as a roofing material, a flooring material, gravestones and memorial tablets, and for electrical insulation. Slate mines are found around the world. 90% of Europe's natural slate used for roofing originates from the Slate Industry in Spain.European Association of Mining Industries website retrieved on 26/01/2010 The major slate mining region in the United Kingdom is ; in |
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] |
Caernarfon
Caernarfon (; ) is a royal town, community and port in Gwynedd, Wales, with a population of 9,852 (with Caeathro). It lies along the A487 road, on the eastern shore of the Menai Strait, opposite the Isle of Anglesey. The city of Bangor is to the north-east, while Snowdonia fringes Caernarfon to the east and south-east. Carnarvon and Caernarvon are Anglicised spellings that were superseded in 1926 and 1974 respectively. Abundant natural resources in and around the Menai Strait enabled human habitation in prehistoric Britain. The Ordovices, a Celtic tribe, lived in the region during the period known as Roman Britain. The Roman fort Segontium was established around AD 80 to subjugate the Ordovices during the Roman conquest of Britain. The Romans occupied the region until the end of Roman rule in Britain in 382, after which Caernarfon became part of the Kingdom of Gwynedd. In the late 11th century, William the Conqueror ordered the construction of a motte-and-bailey cas ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
De Winton
De Winton & Co (1854–1901) were engineers in Caernarfon, Wales. They built, amongst other things, vertical boilered narrow gauge locomotives for use in Welsh slate mines and other industrial settings. At least six De Winton locomotives have been preserved. But these quarry tramway locomotives, for which in the 21st century they are largely remembered, were just a small part of this company's engineering output. Overview The company had its origins in a small foundry built on the slate wharf at Caernarfon by Owen Thomas in the 1840s. He subsequently went into partnership with Jeffreys Parry de Winton and the firm developed as the Union Foundry. Manufactures included street gaslight columns and all manner of street furniture. When the Carnarvonshire Railway was being built under Castle Square, the tunnel roof was supported by iron beams supplied by De Winton's and their name can still be seen at the entrance to the tunnel, which is now used as a road underpass. The foundry wa ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
East London Harbour 0-4-0VB
The East London Harbour 0-4-0VB of 1873 was a South African steam locomotive from the pre-Union era in the Cape of Good Hope. In 1847, the government of the Cape of Good Hope established harbour boards at its three major ports, Table Bay, Port Elizabeth and East London. While railway lines were laid at all these harbours, trains were for the most part initially hauled by oxen or mules.Abbott, Rowland A.S. (1989). ''Vertical Boiler Locomotives and Railmotors built in Great Britain''. Oakwood Press. The first steam locomotive to see service at East London Harbour was a Brunel gauge engine which was obtained for work on breakwater construction in 1873 and placed in service in 1874. It was a engine, similar in general appearance to the American ''Grasshopper'' type. Four of them were acquired between 1873 and 1880. The harbour boards When the requirement for improved harbour facilities for the handling of ships and cargoes became apparent, the Cape Government established harbo ...

Chaplin's Patent Distilling Apparatus With Steam Pump
The Chaplin's patent distilling apparatus with Steam pump for circulating water attached was an early design of an evaporator, a device for producing fresh water on board ship by distillation of seawater. An example of this apparatus has been recovered from the wreck of (1872), an auxiliary steamship used in Australia to transport passengers and trade goods before ultimately sinking in Port Gregory, Western Australia in 1872. It is purported that the Alexander Chaplin distiller from the ''Xantho'' wreck is the only known surviving example of a Chaplin distilling apparatus on board a vessel of this period. Manufacturer Alexander Chaplin & Co. (also known as A.C. and Co., Alex. Chaplin & Co.) was a manufacturing syndicate based in the United Kingdom during the mid-19th century to early 20th century with its manufacturing and engineering plant facilities located at Cranstonhill Engine Works, Glasgow.
