Thomas Savery (/ ˈ s eɪ v ər i /; c. 1650 – 15 May 1715) was an English inventor and engineer.He invented the first commercially used steam-powered device, a steam pump [1] which is often referred to as the "Savery engine".
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.

In 1698 Thomas Savery patented a steam-powered pump he called the "Miner's Friend", [6] essentially identical to Somerset's design and almost certainly a direct copy. [citation needed] [7] The process of cooling and creating the vacuum was fairly slow, so Savery later added an external cold water spray to quickly cool the steam.
The study also proposes replacing the water of a Savery engine with a piston, which is pulled on by the vacuum in a cylinder after steam inside is condensed, but he was unable to build the device. 1718 ( 1718 ) : Jean Desaguliers introduces an improved version of the Savery engine, which includes safety valves and a two-way valve that operated ...
Thomas Savery is considered the inventor of the first commercially used steam powered device, a steam pump that used steam pressure operating directly on the water. The first commercially successful engine that could transmit continuous power to a machine was developed in 1712 by Thomas Newcomen .
Timeline of motor and engine technology (c. 30–70 AD) – Hero of Alexandria describes the first documented steam-powered device, the aeolipile. [1] 13th century – Chinese chronicles wrote about a solid-rocket motor used in warfare. 1698 – Thomas Savery builds a steam-powered water pump for pumping water out of mines. [2]
Prior to 1698 and the invention of the Savery engine, horses were used to power pulleys, attached to buckets, which lifted water out of flooded salt mines in England. In the years to follow, more variations of steam engines were built, such as the Newcomen engine, and later the Watt engine. In time, these early engines would eventually be ...
