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 ...
History of the steam 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]
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] 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.
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.
The Watt steam engine design was an invention of James Watt that became synonymous with steam engines during the Industrial Revolution, and it was many years before significantly new designs began to replace the basic Watt design. The first steam engines, introduced by Thomas Newcomen in 1712, were of the "atmospheric" design.
The first commercial steam-powered device was a water pump, developed in 1698 by Thomas Savery. [15] It used condensing steam to create a vacuum which raised water from below and then used steam pressure to raise it higher. Small engines were effective though larger models were problematic.
It could not pump water higher than 9 metres (30 ft) above water level. 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 ...
