Developing the atmospheric engine

Newcomen's great achievement was his steam engine, developed around 1712; combining the ideas of
Thomas Savery Thomas Savery (; c. 1650 – 15 May 1715) was an English inventor and engineer. He invented the first commercially used steam-powered device, a steam pump which is often referred to as the "Savery engine". Savery's steam pump was a revolutiona ...

at the bottom of the mine. The "fire engine" was not very effective and could not work beyond a limited depth of around thirty feet. Newcomen replaced the receiving vessel (where the steam was condensed) with a cylinder containing a piston based on Papin's design. Instead of the vacuum drawing in water, it drew down the piston. This was used to work a beam engine, in which a large wooden beam rocked upon a central

. On the other side of the beam was a chain attached to a pump at the base of the mine. As the steam cylinder was refilled with steam, readying it for the next power stroke, water was drawn into the pump cylinder and expelled into a pipe to the surface by the weight of the machinery.

Later life and death

Comparatively little is known of Newcomen's later life. After 1715 the engine affairs were conducted through an unincorporated company, the ' Proprietors of the Invention for Raising Water by Fire'. Its secretary and treasurer was John Meres, clerk to the Society of Apothecaries in London. That society formed a company which had a monopoly on supplying medicines to the Navy providing a close link with Savery, whose

After Newcomen

The Newcomen engine held its place without material change for about 75 years, spreading gradually to more areas of the UK and mainland Europe. At first brass cylinders were used, but these were expensive and limited in size. New iron casting techniques pioneered by the

, who built many large engines of this type in the early 1770s; his improvements were rapidly adopted. By 1775 about 600 Newcomen engines had been built, although many of these had worn out before then, and been abandoned or replaced. The Newcomen Engine was by no means an efficient machine, although it was probably as complicated as engineering and materials techniques of the early 18th century could support. Much heat was lost when condensing the steam, as this cooled the cylinder. This did not matter unduly at a colliery, where unsaleable small coal (slack) was available, but significantly increased the mining costs where coal was not readily available, as in Cornwall. Newcomen's engine was gradually replaced after 1775 in areas where coal was expensive (especially in

to collect substantial royalties based on the fuel saved. Watt subsequently made other improvements, including the double-acting engine, where both the up and down strokes were power strokes. These were especially suitable for driving textile mills, and many Watt engines were employed in these industries. At first attempts to drive machinery by Newcomen engines had mixed success, as the single power stroke produced a jerky motion, but use of flywheels and better engineering largely overcame these problems. By 1800, hundreds of non-Watt rotary engines had been built, especially in collieries and ironworks where irregular motion was not a problem but also in textile mills. Despite Watt's improvements, Common Engines (as they were then known) remained in use for a considerable time, and many more Newcomen engines than Watt ones were built even during the period of Watt's patent (up to 1800), as they were cheaper and less complicated. Of over 2,200 engines built in the 18th century, only about 450 were Watt engines. Elements of Watt's design, especially the Separate Condenser, were incorporated in many "pirate" engines. Even after 1800 Newcomen type engines continued to be built and condensers were added routinely to these. They were also commonly retro-fitted to existing Newcomen engines (the so-called "pickle-pot" condenser).
