Why did Newcomen and Watt improve the original design of the steam engine that was created by Thomas Savery?
Thomas Newcomen, (baptized February 28, 1664, Dartmouth, Devon, England—died August 5, 1729, London), British engineer and inventor of the atmospheric steam engine, a precursor of James Watt’s engine.
In about 1712 another Englishman, Thomas Newcomen, developed a more efficient steam engine with a piston separating the condensing steam from the water. In 1765 James Watt greatly improved the Newcomen engine by adding a separate condenser to avoid heating and cooling the cylinder with each stroke.
James Watt did not invent the steam engine. He did, however, improve the engine apparatus. In 1764 Watt observed a flaw in the Newcomen steam engine: it wasted a lot of steam. Watt deduced that the waste resulted from the steam engine’s single-cylinder design.
Neither Newcomen nor Calley was educated in mechanical engineering, and they corresponded with scientist Robert Hooke, asking him to advise them about their plans to build a steam engine with a steam cylinder containing a piston similar to that of Denis Papin’s.
Newcomen was an ironmonger by profession, but made a significant contribution to the Industrial Revolution with his invention of the atmospheric steam engine.
The Newcomen Memorial Engine in Dartmouth, England. in 1698, employed a piston in a cylinder, the vacuum pulling the piston down to the bottom of the cylinder when water was injected into it, cooling the steam.
In 1787, John Fitch demonstrated a working model of the steamboat concept on the Delaware River. The first truly successful design appeared two decades later. It was built by Robert Fulton with the assistance of Robert R. Livingston, the former U.S. minister to France.
In 1698 Thomas Savery patented a pump with hand-operated valves to raise water from mines by suction produced by condensing steam. In about 1712 another Englishman, Thomas Newcomen, developed a more efficient steam engine with a piston separating the condensing steam from the water.
How does the Newcomen engine work? His engine utilised a piston working within an open topped cylinder. The piston is connected by chains to a rocking beam. … The vacuum then pulls the piston down and, via the rocking beam, raises the plunger in the water pump.
Then came the steam engine. It was invented by Richard Arkwright in 1786. These two inventions revolutionised cotton textile weaving in England.
James Watt did not invent the steam engine; he improved on the work of Newcomen by adding a condenser. Edison did not invent the light bulb; he make it practical by selecting a carbon fiber filament and enclosing it in a vacuum.
In 1705 Newcomen married Hannah Weymouth and they had two sons and a daughter.
The first useful steam engine was invented by Thomas Newcomen in 1712. The Newcomen engine was used to pump water out of mines. Steam power really took off with improvements made by James Watt in 1778. The Watt steam engine improved the efficiency of steam engines considerably.
Newcomen’s piston design effectively created a separation between the water being pumped out and the cylinder used to create the pumping power. This greatly improved on the efficiency of Savery’s original design.
It has been estimated that it required at least 10 to 15 years of development. Both the Newcomen and Savery engines were based upon the use of condensed steam; however, they also differed in important fundamentals. The basic principle of Newcomen’s engine was simple.

The English railway engineers George Stephenson (1781-1848) and his son, Robert Stephenson (1803-1859), pioneered in steam railway engineering, which led directly to the onset of the railway age in Britain.
Watt initially worked as a maker of mathematical instruments, but soon became interested in steam engines. … He designed a separate condensing chamber for the steam engine that prevented enormous losses of steam. His first patent in 1769 covered this device and other improvements on Newcomen’s engine.
James Hargreaves, Hargreaves also spelled Hargraves, (baptized January 8, 1721, Oswaldtwistle, Lancashire, England—died April 22, 1778, Nottingham, Nottinghamshire), English inventor of the spinning jenny, the first practical application of multiple spinning by a machine.
The Watt steam engine, alternatively known as the Boulton and Watt steam engine, was an early steam engine and was one of the driving forces of the Industrial Revolution. James Watt developed the design sporadically from 1763 to 1775 with support from Matthew Boulton.
In 1769, a Scotsman named James Watt invented an engine that was run by steam. Once inventors learned about the steam engine they began to experiment with using it to run boats. The first man to build a steamboat in the United States was John Fitch.
Over time engineers and riverboat captains improved steamboats. Engines became much more powerful than that of the New Orleans, the first steamboat to travel the length of the Ohio and the Mississippi Rivers. Boats grew in size and luxury. Steam power continued to be used into the twentieth century.
The era of the steamboat began in the late 1700s, thanks initially to the work of Scotsman James Watt. In 1769, Watt patented an improved version of the steam engine that helped usher in the Industrial Revolution and spurred other inventors to explore how steam technology could be used to propel ships.
In 1712, Thomas Newcomen invented an effective and practical steam engine. The steam engine he designed consisted of a piston and cylinder arrangement coupled to a pump through a rocking beam.

Abstract: In the 1890s, Rudolf Diesel invented an efficient, compression ignition, internal combustion engine that bears his name. Early diesel engines were large and operated at low speeds due to the limitations of their compressed air-assisted fuel injection systems.
Thomas Savery, (born c. 1650, Shilstone, Devonshire, Eng. —died 1715, London), English engineer and inventor who built the first steam engine.
Thomas Newcomen designed steam engine. He designed it in the year 1712. Question 18.
The new steam engine was invented by James Watt (1736-1819).
James Watt FRS FRSE was a Scottish inventor, mechanical engineer, and chemist who improved on Thomas Newcomen’s 1712 Newcomen steam engine with his Watt steam engine in 1776, which was fundamental to the changes brought by the Industrial Revolution in both his native Great Britain and the rest of the world.
