Steam Engine
A steam engine is a heat engine that performs Work (physics), mechanical work using steam as its working fluid. The steam engine uses the force produced by steam pressure to push a piston back and forth inside a Cylinder (locomotive), cylinder. This pushing force can be transformed by a connecting rod and Crank (mechanism), crank into rotational force for work. The term "steam engine" is most commonly applied to reciprocating engines as just described, although some authorities have also referred to the steam turbine and devices such as Hero's aeolipile as "steam engines". The essential feature of steam engines is that they are external combustion engines, where the working fluid is separated from the combustion products. The ideal thermodynamic cycle used to analyze this process is called the Rankine cycle. In general usage, the term ''steam engine'' can refer to either complete steam plants (including Boiler (power generation), boilers etc.), such as railway steam locomot ...

Harlem Railroad
The New York and Harlem Railroad (now the Metro-North Railroad's Harlem Line) was one of the first railroads in the United States, and was the world's first street railway. Designed by John Stephenson, it was opened in stages between 1832 and 1852 between Lower Manhattan Island to and beyond Harlem. Horses initially pulled railway carriages, followed by a conversion to steam engines, then on to battery-powered Julien electric traction cars. In 1907, the then leaseholders of the line, New York City Railway, a streetcar operator, went into receivership. Following a further receivership in 1932, the New York Railways Corporation converted the line to bus operation. The Murray Hill Tunnel now carries a lane of road traffic, but not the buses. The line became part of the New York Central Railroad system with trackage rights granted to the New York, New Haven and Hartford Railroad into Manhattan. It is now part of the Metro-North Railroad system, and the only Manhattan trackage o ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Poppet Valves
A poppet valve (also sometimes called mushroom valve) is a valve typically used to control the timing and quantity of petrol (gas) or vapour flow into or out of an engine, but with many other applications. It consists of a hole or open-ended chamber, usually round or oval in cross-section, and a plug, usually a disk shape on the end of a shaft known as a valve stem. The working end of this plug, the valve face, is typically ground at a 45° bevel to seal against a corresponding valve seat ground into the rim of the chamber being sealed. The shaft travels through a valve guide to maintain its alignment. A pressure differential on either side of the valve can assist or impair its performance. In exhaust applications higher pressure against the valve helps to seal it, and in intake applications lower pressure helps open it. Etymology The word poppet shares etymology with "puppet": it is from the Middle English ''popet'' ("youth" or "doll"), from Middle French ''poupette'', whic ...

Corliss Engine
A Corliss steam engine (or Corliss engine) is a steam engine, fitted with rotary valves and with variable valve timing patented in 1849, invented by and named after the US engineer George Henry Corliss of Providence, Rhode Island. Corliss assumed the original invention from Frederick Ellsworth Sickels (1819- 1895), who held the patent (1829) in the US patent office. Engines fitted with Corliss valve gear offered the best thermal efficiency of any type of stationary steam engine until the refinement of the uniflow steam engine and steam turbine in the 20th century. Corliss engines were generally about 30 percent more fuel efficient than conventional steam engines with fixed cutoff. This increased efficiency made steam power more economical than water power, allowing industrial development away from millponds. Corliss engines were typically used as stationary engines to provide mechanical power to line shafting in factories and mills and to drive Electric generator#Dynamo, dynamos ...

George Henry Corliss
George Henry Corliss (June 2, 1817 – February 21, 1888) was an American mechanical engineer and inventor, who developed the Corliss steam engine, which was a great improvement over any other stationary steam engine of its time. The Corliss engine is widely considered one of the more notable engineering achievements of the 19th century. It provided a reliable, efficient source of industrial power, enabling the expansion of new factories to areas which did not readily possess reliable or abundant water power. Corliss gained international acclaim for his achievements during the late 19th century and is perhaps best known for the ''Centennial Engine'', which was the centerpiece of the 1876 Centennial Exposition in Philadelphia. Early life George Henry Corliss was born June 2, 1817, the second child of Dr. Hiram and Susan (Sheldon) Corliss, at Easton, New York, near the Vermont border. The son of a physician, he attended local schools until age 14, when he began working in a ge ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Civil Engineer
A civil engineer is a person who practices civil engineering – the application of planning, designing, constructing, maintaining, and operating infrastructure while protecting the public and environmental health, as well as improving existing infrastructure that may have been neglected. Civil engineering is one of the oldest engineering disciplines because it deals with constructed environment including planning, designing, and overseeing construction and maintenance of building structures, and facilities, such as roads, railroads, airports, bridges, harbors, channels, dams, irrigation projects, pipelines, power plants, and water and sewage systems. The term "civil engineer" was established by John Smeaton in 1750 to contrast engineers working on civil projects with the military engineers, who worked on armaments and defenses. Over time, various sub-disciplines of civil engineering have become recognized and much of military engineering has been absorbed by civil engineering. ...

American Society Of Civil Engineers
The American Society of Civil Engineers (ASCE) is a tax-exempt professional body founded in 1852 to represent members of the civil engineering profession worldwide. Headquartered in Reston, Virginia, it is the oldest national engineering society in the United States. Its constitution was based on the older Boston Society of Civil Engineers from 1848. ASCE is dedicated to the advancement of the science and profession of civil engineering and the enhancement of human welfare through the activities of society members. It has more than 143,000 members in 177 countries. Its mission is to provide essential value to members, their careers, partners, and the public; facilitate the advancement of technology; encourage and provide the tools for lifelong learning; promote professionalism and the profession; develop and support civil engineers. History The first serious and documented attempts to organize civil engineers as a professional society in the newly created United States were ...

Men Of Progress
Jordan Lawrence Mott (1799 — 1866) was an American inventor and industrialist. He established the J. L. Mott Iron Works in New York City. His father was Jacob Mott, an alderman of New York in 1804-1810 and at one time acting mayor of the city, after whom Mott Street was named. Jacob's wife was related to James Lawrence, a naval officer in the War of 1812. The family are said to be descended from Adam Mott from Essex, England, who arrived in the United States before 1647. Mott's son (1829 - 26 July 1915) was Jordan Lawrence Mott Jr, and was married to Marianna Seaman, who died in 1898. He followed his father as President of the foundry business and was described at his death as "for many years a notable figure in the life of the city". - Obituary of JLMott jr His son Jordan Lawrence Mott III (born 13 May 1857 – 7 January 1932) married Katherine Jerome Purdy.
