Thomas Newcomen Facts
Thomas Newcomen (baptized February 28, 1664 to August 5, 1729) was an English inventor. He built the first steam driven water pump, the Newcomen steam engine. He was an ironmonger who specialized in designing and manufacturing tools for the mining industry.
Interesting Thomas Newcomen Facts:
Thomas Newcomen was born in Dartmouth, England.
As mines became progressively deeper, flooding became a major problem and resulted in the death of miners.
The usual method of removing the water was to use horses to pull buckets of water out of the mine but this was very slow.
Thomas Savery and Denis Papin invented a steam syphon pump but it was not efficient.
The Savery engine used steam to create a vacuum which lifted water from a mine.
Around 1712 he developed the steam driven water pump.
It could not operate below thirty feet and was not very effective.
Newcomen replaced the simple steam condensation cylinder with a piston cylinder and added a lever to transfer the force of the piston to the pump shaft.
In the new design used the vacuum to pull down a piston rather than drawing in the water directly.
Newcomen developed this new engine with his partner, John Calley.
Because Savery already had a patent on a steam driven water pump, Newcomen went into partnership with him.
The first Newcomen engine was used at the Conygree Coalworks near Dudley.
Its cylinder was almost eight feet long and twenty-one inches in diameter.
By 1733 over 100 Newcomen engines were in use in Britain and in Europe.
Some of their locations were in coal mines in Warwickshire and near Newcastle upon Tyne and in tin and copper mines in Cornwall.
The Newcomen engine was used unchanged for almost 75 years and almost 2000 of them were built.
In 1964 the Newcomen Society of London created a museum at Dartmouth with a working Newcomen engine that was built about 1725.
Very little is known of Newcomen's personal life except that he was a lay minister in the Baptist church.
