Newcomen took years to explore the possibility of replacing the horse power behind the water pump concept and he came up with a steam engine based on atmospheric pressure. He had help from a plumber named John Cawley (Calley).
	However when Thomas Newcomen applied for a patent on the Atmospheric Steam Engine he found out that a similar mechanical device had already been given a patent. In 1698 Thomas Savery had been awarded a patent for his pump. The Savery patent license covered a broad range of steam pumps. Newcomen and Savery got together and Newcomen somehow convinced Savery of the superior quality of his pump. The atmospheric type of compression was innovative and delivered a greater intensity of pressure than simply the steam power. In 1712 the first atmospheric steam engine was put to use in Staffordshire. This type of engine was used extensively in mines for the purpose of draining excess water in the pits and tunnels for several years. The James Watts engine came along as another innovation on the atmospheric steam engine.
