Steam Engines In The 1800s
Transcript of Steam Engines In The 1800s
diagrams notes Steam engines and locomotives ARE NOT the same things even though everyone mixes them up. the steam engine is the engine that moves the locomotive hence the word ENGINE. http://science.howstuffworks.com/transport/engines-equipment/steam1.htm http://wimp.com/steamengine/ History Recources Used by us http://www.animatedengines.com/newcomen.html Like many other modern inventions, the steam engine had a long evolution. It was first conceived of by Greek scientist Hero of Alexandria in the first century a.d. The mathematician invented many "contrivances" that were operated by water, steam, or compressed air. These included not only a fountain and a fire engine, but the steam engine. Many centuries later, Englishman Thomas Newcomen (1663-1729) developed an early steam engine (about 1711) that was used to pump water. He was improving on a previous design, which had been patented by another inventor in 1698.
But it was Scottish inventor James Watt (1736-1819) who substantially improved Newcomen's machine, patenting his own steam-powered engine in 1769. It was the first practical steam engine, and Watt's many improvements to the earlier technology paved the way for the use of the engine in manufacturing and transportation during the Industrial Revolution (c. 1750-c. 1850); Britain was just on the cusp of this new age when Watt patented his engine. The steam engine was eventually replaced by more efficient devices such as the turbine (developed in the 1800s), the electric motor (also developed in the 1800s), the internal-combustion engine (first practical engine built in 1860), and the diesel engine (patented 1892). Nevertheless, James Watt's steam engine played a critical role in moving society from an agricultural- to industrial-based economy. Watt's legacy also includes the use of "horsepower" and "watts" as units of measure. Aluminum Foil
A few of the Highlights 100 A.D. Hero's Engine is Created
5th-15th Centuries Needs of the people surpass the ability of human and animal labor
1606 Giovanni Battista Della Porta uses steam to make water rise through a column
1690 Denys Papin discovers a way to produce a vacuum using steam but does not pursue the knowledge
1698 Thomas Savery combines the force of steam with the pressure of the atmosphere and patents the first atmospheric engine
1712 Thomas Newcomen produces a self acting atmospheric engine
1769 James Watt is granted a patent for the Separate Condenser
1780 James Pickard and Matthew Wasborough create an engine with rotary motion by fitting a crank, rod and flywheel to
1783 A double acting engine is introduced by Watt - Steam pushes on each side of the piston alternately as opposed to just one side
1786 Boulton and Watt produce a double acting rotative engine 1802 A steam railway locomotive is built at Coalbrookdale, Shropshire
A stern wheel steam paddle tug is created by William Symington
1807 Robert Fulton's ship the "Clermont" becomes the first steamship to provide regular passenger service in America
1825 The First Public Railway to use steam locomotives opens
1827 The era of locomotive success begins in Britain
1838 The Great Western Railway opens
1844 The "Lancashire" boiler is introduced in Manchester by William Fairbairn
1846 The Regulation of Railways (Gauge) Act is passed
The "Tank Engine" is born
1850 Randolph Elder fits the first marine compound engine
1865 Commuter Traffic becomes prominent in large cities - Passenger traffic locomotives are introduced by the railways
1878 Willans patents the high speed fully enclosed "inverted vertical" engine
1890 Charles Pain patents the forced-lubrication-high-speed-enclosed engine
1898 The first British express locomotive travels on the Great Northern Railway
1906 Superheating of steam is invented by Dokter Schmidt and used in British Railway locomotives
1938 The streamlined "Pacific" 4-6-2 locomotive "Mallard" reaches a speed of 126 miles per hour (201 kph),
This speed still stands as a world record.
1960 The final steam locomotive is built by British Railways - "Evening Star" Disadvantages First of all, the steam engine brought huge pollution to the environment. Since people started to use the steam engine, they kept pillage the natural resources like coal, petroleum, natural gas, metal mineral resource, etc.
What’s more, the Home trash, electronic trash, industrial refuse, industrial waste that people produce because of the product of the steam engine is also a huge harming to the environment. Natural Resorces Used The first commercial steam-powered device was a water pump, developed in 1698 by Thomas Savery. It used a vacuum to raise water from below, then used steam pressure to raise it higher. Small engines were effective though larger models were problematic. The history of the steam engine stretches back as far as the first century AD; the first recorded rudimentary steam engine being the aeolipile described by Greek mathematician Hero of Alexandria. In the following centuries, the few steam-powered "engines" known were, like the aeolipile. Using boiling water to produce mechanical motion goes back about 2,000 years, but early devices were not practical. Since the late 1700s steam engines have become a major source of mechanical power. The first applications were removing water from mines. In 1781 James Watt patented a steam engine that produce continuos rotative motion Steam Engines How it Works Water Fire Copper and Locomotives ON/OFF Inventors: Thomas Savery, Thomas Newcomen, James Watt
Thomas Savery (1650-1715)
Thomas Savery was an English military engineer and inventor who in 1698, patented the first crude steam engine, based on Denis Papin's Digester or pressure cooker of 1679.
Thomas Savery had been working on solving the problem of pumping water out of coal mines, his machine consisted of a closed vessel filled with water into which steam under pressure was introduced. This forced the water upwards and out of the mine shaft. Then a cold water sprinkler was used to condense the steam. This created a vacuum which sucked more water out of the mine shaft through a bottom valve http://www.animatedengines.com/locomotive.html Fun Facts Steam engines are still used today to help run nuclear power plants.
The Watt - a unit of power familiar today when dealing with lightbulbs - was named after James Watt.
James Watt came up with the term 'horsepower' as a way to help explain how much work his steam engines could do for a potential buyer.
james watt inveented the steam engine so that goods could be transported to their destenation in less time than by horse. Condenser: An instrument for cooling air or gases.
Cylinder: The chamber of an engine in which the piston moves.
Piston: A sliding piece that is moved by or moves against fluid pressure within a cylindrical vessel or chamber.
Turbine: An engine that moves in a circular motion when force, such as moving water, is applied to its series of baffles (thin plates or screens) radiating from a central shaft.

*Watts was a big part in the creation of the steam engine, but Thomas was a bigger part because he came up with the project. Candle Hole Punch Dowel/pencil pliers bowl We used our brains for this!!! Advantages Goods are more fresh because they get transported faster
they could get people to their destination faster notes
about hardships copper tubing was hard to coil. More productive because
