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 ...
Collects steam at the top of the boiler (well above the water level) so that it can be fed to the engine via the main steam pipe, or dry pipe, and the regulator/throttle valve. [2] [5] [6]: 211–212 [3]: 26 Air pump / Air compressor Westinghouse pump (US+) Powered by steam, it compresses air for operating the train air brake system.
Twins Francis E. Stanley (1849–1918) and Freelan O. Stanley (1849–1940) founded the company, after selling their photographic dry plate business to Eastman Kodak. They made their first car in 1897. During 1898 and 1899, they produced and sold over 200 cars, more than any other U.S. maker. [1]
During the 1830s, the most popular valve drive for steam locomotives was known as gab motion in the United Kingdom and V-hook motion in the United States. [3] The gab motion incorporated two sets of eccentrics and rods for each cylinder; one eccentric was set to give forward and the other backwards motion to the engine and one or the other could accordingly engage with a pin driving the ...

The Amoskeag Locomotive Works, in Manchester, New Hampshire, built steam locomotives at the dawn of the railroad era in the United States. The locomotive works operated as a division of the Amoskeag Manufacturing Company between 1848 and 1859. Besides building locomotives for railroad use, Amoskeag also built steam fire engines until 1876.
In that year he conducted, in behalf of a committee of the American Institute, a series of experiments on steam boilers, in which, for the first time, all losses of heat were noted, and by condensing all the steam generated, the quantity of water entrained by the steam was accurately noted.

A drawback of condensing the exhaust steam is that it is no longer available to draw the fire, by use of the blastpipe. The draught must thus be generated instead by a steam-driven fan. [2] Where possible, this has been arranged to use exhaust steam, although in some cases live steam was required, with extra steam and thus fuel consumption.
