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.

Engine balance refers to how the inertial forces produced by moving parts in an internal combustion engine or steam engine are neutralised with counterweights and balance shafts, to prevent unpleasant and potentially damaging vibration. The strongest inertial forces occur at crankshaft speed (first-order forces) and balance is mandatory, while ...
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 ...
Hammer blow. In rail terminology, hammer blow or dynamic augment is a vertical force [1] which alternately adds to and subtracts from the locomotive's weight on a wheel. It is transferred to the track by the driving wheels [2] of many steam locomotives. It is an out-of-balance force on the wheel (known as overbalance [3]).
A steam locomotive is a locomotive that provides the force to move itself and other vehicles by means of the expansion of steam. [1]: 80 It is fuelled by burning combustible material (usually coal, oil or, rarely, wood) to heat water in the locomotive's boiler to the point where it becomes gaseous and its volume increases 1,700 times.
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 ...
A steam motor is a form of steam engine used for light locomotives and light self-propelled motor cars used on railways. [1] The origins of steam motor cars for railways go back to at least the 1850s, if not earlier, as experimental economizations for railways or railroads with marginal budgets. These first examples, at least in North America ...
The Argentinian engineer Livio Dante Porta in the development of Stephensonian railway locomotives incorporating advanced steam technology was a precursor of the 'Modern Steam' movement from 1948. [ 11 ] : 3–6 Where possible, Porta much preferred to design new locomotives, but more often in practice he was forced to radically update old ones ...
