Thomas Savery (/ ˈseɪvəri /; 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". Savery's steam pump was a revolutionary method of pumping water, which improved mine drainage and made widespread public ...
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 first steam engine to be applied industrially was the "fire-engine" or "Miner's Friend", designed by Thomas Savery in 1698. This was a pistonless steam pump, similar to the one developed by Worcester. Savery made two key contributions that greatly improved the practicality of the design.
1698 (): Thomas Savery introduces a steam pump he calls the Miner's Friend. [8] It is almost certainly a direct copy of Somerset's design. One key improvement is added later, replacing the cold water flow on the outside of the cylinder with a spray directly inside it.
Thomas Savery's steam pump. The industrial use of steam power started with Thomas Savery in 1698. He constructed and patented in London the first engine, which he called the "Miner's Friend" since he intended it to pump water from mines. Early versions used a soldered copper boiler which burst easily at low steam pressures.

He was an ironmonger by ...
The atmospheric engine, invented by Thomas Newcomen in 1712, combined the ideas of Thomas Savery, who he was forced to go into partnership with due to Savery's patent, and Denis Papin, using his invention of a piston. It was the first practical application of the steam engine in a mine and was used to dewater coal and tin mines.
The first commercially successful engine that could transmit continuous power to a machine was the atmospheric engine, invented by Thomas Newcomen around 1712. [b] [22] It improved on Savery's steam pump, using a piston as proposed by Papin. Newcomen's engine was relatively inefficient, and mostly used for pumping water.
