Leeds Forge Company
The Leeds Forge Company manufactured corrugated furnaces for marine steam engine boilers and later, pressed steel railway vehicles, in Leeds, England. Early history The company was founded by Samson Fox, who was born in 1838 in Bradford, Yorkshire. Fox had been apprenticed to Smith, Beacock and Tannett of Victoria Foundry, Leeds, successors to Fenton, Murray and Jackson, who were early railway locomotive builders. While at Smith, Beacock and Tannett, Fox became their travelling representative, and became acquainted with Scotts Shipbuilding and Engineering Company of Greenock, who were major shipbuilders on the Firth of Clyde. Scotts provided a substantial proportion of the capital to establish the Leeds Forge at Castleton Field, Armley, Leeds in 1874, initially producing straight and cranked locomotive axles. The Corrugated Furnace In 1877 Fox lodged a patent for his Corrugated Furnace. This was a tube (initially iron, later steel) heated and swaged (rolled) under pressure to ...

Marine Steam Engine
A marine steam engine is a steam engine that is used to power a ship or boat. This article deals mainly with marine steam engines of the reciprocating type, which were in use from the inception of the steamboat in the early 19th century to their last years of large-scale manufacture during World War II. Reciprocating steam engines were progressively replaced in marine applications during the 20th century by steam turbines and marine diesel engines. History The first commercially successful steam engine was developed by Thomas Newcomen in 1712. The steam engine improvements brought forth by James Watt in the later half of the 18th century greatly improved steam engine efficiency and allowed more compact engine arrangements. Successful adaptation of the steam engine to marine applications in England would have to wait until almost a century after Newcomen, when Scottish engineer William Symington built the world's "first practical steamboat", the '' Charlotte Dundas'', in 1802.

New South Wales Standard Suburban Carriage Stock
The New South Wales Standard suburban carriage stock are a class of electric multiple units that were operated by the New South Wales Government Railways and its successors between 1926 and 1992. They served on the Sydney suburban network. In the years before their withdrawal, they were nicknamed ''Red Rattlers''.This term was imported from Victoria and was never a contemporaneous colloquialism. History To provide rolling stock for the electrification of Sydney's suburban rail network, steel carriages were ordered."Sydney's Electric Trains from 1926 to 1960" '' ARHS Bulletin'' issue 761 March 2001 pages 90-93 The initial 50 power cars were built in England by Leeds Forge Company and shipped to Australia in knocked-down condition. They were assembled by Eveleigh Carriage Workshops (10) and Clyde Engineering (40) between April and October 1925.

Joliet, Illinois
Joliet ( ) is a city in Will County, Illinois, Will and Kendall County, Illinois, Kendall counties in the U.S. state of Illinois, southwest of Chicago. It is the county seat of Will County. At the 2020 United States Census, 2020 census, the city was the List of cities in Illinois, third-largest in Illinois, with a population of 150,362. History In 1673, Louis Jolliet, along with Father Jacques Marquette, paddled up the Des Plaines River and camped on a huge earthwork mound, a few miles south of present-day Joliet. Maps from Jolliet's exploration of the area showed a large hill or mound down river from Chicago, labeled Mont Joliet. The mound has since been flattened due to mining. In 1833, following the Black Hawk War, Charles Reed built a cabin along the west side of the Des Plaines River. Across the river in 1834, James B. Campbell, treasurer of the canal commissioners, laid out the village of "Juliet", a corruption of "Joliet" that was also in use at the time. Just before t ...

Barsi Light Railway
Barsi Light Railway (BLR) was a long, narrow-gauge railway between Miraj and Latur in the state of Maharashtra in India. It was the brainchild of British engineer Everard Calthrop, and regarded as having revolutionised narrow-gauge railway construction in India. Classification It was labeled as a Class II railway according to Indian Railway Classification System of 1926. Background: The Barsi Tramway Project The Barsee Tramway was a project, proposed in 1862, to construct a bullock driven Tramway 'to connect Barsee with the Barsee railway station’. In the event the Tramway was not installed but the groundwork had been completed with the construction of the earth works, cuttings and bridges and was completed in 1870 By the 1870’s Barsi had become the spelling of the town. Barsi Town was connected to Barsi Road Station , on the GIPR, a distance of 22 miles (35 km), utilising the completed groundworks providing a 24 foot (7.3 m) wide roadway with 'hard shoulders' a ...

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] |
Everard Calthrop
Everard Richard Calthrop (3 March 1857 – 30 March 1927) was a British railway engineer and inventor. Calthrop was a notable promoter and builder of narrow-gauge railways, especially of narrow gauge, and was especially prominent in India. His most notable achievement was the Barsi Light Railway, but he is best known in his home country for the Leek and Manifold Valley Light Railway. Calthrop has been described as a "railway genius".Bennett, Paul ''Pickled Passengers – The Narrow Gauge number 219''. Narrow Gauge Railway Society. Later in life he took an interest in aviation, patenting some early designs for parachutes. Early life and career Calthrop was born on 3 March 1857, the eldest son of farmer Everard Calthrop. He had six brothers, one of whom was Sir Guy Calthrop, general manager of the London & North Western Railway. The family lived at Deeping Fen, Lincolnshire, where Calthrop was born, and later at Sutton in the Isle of Ely. Calthrop was educated at Uppingham S ...

Hydraulic Press
A hydraulic press is a machine press using a hydraulic cylinder to generate a compressive force. It uses the hydraulic equivalent of a mechanical lever, and was also known as a Bramah press after the inventor, Joseph Bramah, of England. He invented and was issued a patent on this press in 1795. As Bramah (who is also known for his development of the flush toilet) installed toilets, he studied the existing literature on the motion of fluids and put this knowledge into the development of the press. Main principle The hydraulic press depends on Pascal's principle-the pressure throughout a closed system is constant. One part of the system is a piston acting as a pump, with a modest mechanical force acting on a small cross-sectional area; the other part is a piston with a larger area which generates a correspondingly large mechanical force. Only small-diameter tubing (which more easily resists pressure) is needed if the pump is separated from the press cylinder. Pascal's law: Pressu ...
