The 1698 Savery Steam Pump - the first commercially successful steam powered device, built by Thomas Savery [1] The first recorded rudimentary steam engine was the aeolipile mentioned by Vitruvius between 30 and 15 BC and, described by Heron of Alexandria in 1st-century Roman Egypt. [2]
Newcomen's atmospheric steam engine. The first practical mechanical steam engine was introduced by Thomas Newcomen in 1712. Newcomen apparently conceived his machine independently of Savery, but as the latter had taken out a wide-ranging patent, Newcomen and his associates were obliged to come to an arrangement with him, marketing the engine until 1733 under a joint patent.

1790 (): Nathan Read invented the tubular boiler and improved cylinder, devising the high-pressure steam engine. 1791 (): Edward Bull makes a seemingly obvious design change by inverting the steam engine directly above the mine pumps, eliminating the large beam used since Newcomen's designs. About 10 of his engines are built in Cornwall.
Hornblower settled in Belleville and is credited with building the first steam engine in America in 1755. [3] There is some dispute about the validity of the project, since he apparently (and illegally) brought two or three sets of critical engine parts with him from England. [4] [citation needed]
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.
According to the company, the steam engine named Quadrum generates 27% efficiency and runs with 180 °C steam at 8 bar pressure, while a corresponding steam turbine produces just 15% efficiency, requires steam temperature of 240 °C and pressure of 40 bar. The high efficiency comes from a patented crank mechanism, that gives a smooth, pulseless ...

An oscillating cylinder steam engine is a variant of the simple expansion steam engine which does not require valves to direct steam into and out of the cylinder. Instead of valves, the entire cylinder rocks, or oscillates, such that one or more holes in the cylinder line up with holes in a fixed port face or in the pivot mounting ( trunnion ).
