London Steam Carriage
The London Steam Carriage was an early steam-powered road vehicle constructed by Richard Trevithick in 1803 and the world's first self-propelled passenger-carrying vehicle. Cugnot had built a steam vehicle 30 years previously, but that had been a slow-moving artillery tractor, not built to carry passengers. History In 1801, after James Watt's earlier patent on "a carriage propelled by a steam engine" had expired, Richard Trevithick constructed an experimental steam-driven vehicle (''Puffing Devil'') at Camborne, Cornwall. It was equipped with a firebox enclosed within the boiler, with one vertical cylinder, the motion of the single piston being transmitted directly to the driving wheels by means of connecting rods. It was reported as weighing fully loaded, with a speed of on the flat. Trevithick ran this for several hundred yards up a hill with several people hanging on to it. Unfortunately, while the driver and passengers were in a pub celebrating the event, it set fire to ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Spur Gear
Spur gears or straight-cut gears are the simplest type of gear. They consist of a cylinder or disk with teeth projecting radially. Viewing the gear at 90 degrees from the shaft length (side on) the tooth faces are straight and aligned parallel to the axis of rotation. Looking down the length of the shaft, a tooth's cross section is usually not triangular. Instead of being straight (as in a triangle) the sides of the cross section have a curved form (usually involute and less commonly cycloidal) to achieve a constant drive ratio. Spur gears mesh together correctly only if fitted to parallel shafts. No axial thrust is created by the tooth loads. Spur gears are excellent at moderate speeds but tend to be noisy at high speeds. Spur gear can be classified into two pressure angles, 20° being the current industry standard and 14½° being the former (often found in older equipment). Spur gear teeth are manufactured as either involute In mathematics, an involute (also known as an ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
History Of Steam Road Vehicles
The history of steam road vehicles comprises the development of vehicles powered by a steam engine for use on land and independent of rails, whether for conventional road use, such as the steam car and steam waggon, or for agricultural or heavy haulage work, such as the traction engine. The first experimental vehicles were built in the 18th and 19th century, but it was not until after Richard Trevithick had developed the use of high-pressure steam, around 1800, that mobile steam engines became a practical proposition. The first half of the 19th century saw great progress in steam vehicle design, and by the 1850s it was viable to produce them on a commercial basis. This progress was dampened by legislation which limited or prohibited the use of steam-powered vehicles on roads. Nevertheless, the 1880s to the 1920s saw continuing improvements in vehicle technology and manufacturing techniques, and steam road vehicles were developed for many applications. In the 20th century, the ra ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Routledge
Routledge () is a British multinational publisher. It was founded in 1836 by George Routledge, and specialises in providing academic books, journals and online resources in the fields of the humanities, behavioural science, education, law, and social science. The company publishes approximately 1,800 journals and 5,000 new books each year and their backlist encompasses over 70,000 titles. Routledge is claimed to be the largest global academic publisher within humanities and social sciences. In 1998, Routledge became a subdivision and imprint of its former rival, Taylor & Francis Group (T&F), as a result of a £90-million acquisition deal from Cinven, a venture capital group which had purchased it two years previously for £25 million. Following the merger of Informa and T&F in 2004, Routledge became a publishing unit and major imprint within the Informa "academic publishing" division. Routledge is headquartered in the main T&F office in Milton Park, Abingdon, Oxfordshire and ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Islington
Islington () is a district in the north of Greater London, England, and part of the London Borough of Islington. It is a mainly residential district of Inner London, extending from Islington's High Street to Highbury Fields, encompassing the area around the busy High Street, Upper Street, Essex Road (former "Lower Street"), and Southgate Road to the east. Modern definition Islington grew as a sprawling Middlesex village along the line of the Great North Road, and has provided the name of the modern borough. This gave rise to some confusion, as neighbouring districts may also be said to be in Islington. This district is bounded by Liverpool Road to the west and City Road and Southgate Road to the south-east. Its northernmost point is in the area of Canonbury. The main north–south high street, Upper Street splits at Highbury Corner to Holloway Road to the west and St. Paul's Road to the east. The Angel business improvement district (BID), an area centered around the Angel t ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Paddington
Paddington is an area within the City of Westminster, in Central London. First a medieval parish then a metropolitan borough, it was integrated with Westminster and Greater London in 1965. Three important landmarks of the district are Paddington station, designed by the engineer Isambard Kingdom Brunel and opened in 1847; St Mary's Hospital; and the former Paddington Green Police Station (once the most important high-security police station in the United Kingdom). A major project called Paddington Waterside aims to regenerate former railway and canal land between 1998 and 2018, and the area is seeing many new developments. Offshoot districts (historically within Paddington) are Maida Vale, Westbourne and Bayswater including Lancaster Gate. History The earliest extant references to ''Padington'' (or "Padintun", as in the ''Saxon Chartularies'', 959), historically a part of Middlesex, appear in documentation of purported tenth-century land grants to the monks of Westmin ...

William Felton (coachmaker)
William Felton was a London coachmaker from 36 Leather Lane in Holborn, and 254 Oxford Street near Grosvenor Square, and noted for his 1796 illustrated two-volum"''A Treatise on Carriages; comprehending Coaches, Chariots, Phaetons, Curricles, Gigs, Whiskies, &c Together with their Proper Harness in which the Fair Prices of Every Article are Accurately Stated.''"William Felton wrote in the book's introduction that he had no literary pretensions, but rather that his aim was to produce an authoritative guide to the construction, maintenance and repair of horse-drawn coaches. The ''Monthly Review'' agreed that it was not a literary masterpiece, but praised it for its encyclopaedic treatment of the subject. ''The Sporting Magazine'' in its sixth issue was equally complimentary about Felton's ''Treatise''. Richard Trevithick's 1803 London Steam Carriage was the first steam-powered vehicle designed for transporting passengers around London, but was never a commercial success. The car ...

Flywheel
A flywheel is a mechanical device which uses the conservation of angular momentum to store rotational energy; a form of kinetic energy proportional to the product of its moment of inertia and the square of its rotational speed. In particular, assuming the flywheel's moment of inertia is constant (i.e., a flywheel with fixed mass and second moment of area revolving about some fixed axis) then the stored (rotational) energy is directly associated with the square of its rotational speed. Since a flywheel serves to store mechanical energy for later use, it is natural to consider it as a kinetic energy analogue of an electrical inductor. Once suitably abstracted, this shared principle of energy storage is described in the generalized concept of an accumulator. As with other types of accumulators, a flywheel inherently smooths sufficiently small deviations in the power output of a system, thereby effectively playing the role of a low-pass filter with respect to the mechanical velocity ...

Richard Trevithick
Richard Trevithick (13 April 1771 – 22 April 1833) was a British inventor and mining engineer. The son of a mining captain, and born in the mining heartland of Cornwall, Trevithick was immersed in mining and engineering from an early age. He was an early pioneer of steam-powered road and rail transport, and his most significant contributions were the development of the first high-pressure steam engine and the first working railway steam locomotive. The world's first locomotive-hauled railway journey took place on 21 February 1804, when Trevithick's unnamed steam locomotive hauled a train along the tramway of the Penydarren Ironworks, in Merthyr Tydfil, Wales. Turning his interests abroad Trevithick also worked as a mining consultant in Peru and later explored parts of Costa Rica. Throughout his professional career he went through many ups and downs and at one point faced financial ruin, also suffering from the strong rivalry of many mining and steam engineers of the day.
