Timeline of steam power
Steam power developed slowly over a period of several hundred years, progressing through expensive and fairly limited devices in the early 17th century, to useful pumps for mining in 1700, and then to Watt's improved steam engine designs in the late 18th century. It is these later designs, introduced just when the need for practical power was growing due to the Industrial Revolution, that truly made steam power commonplace.

- 1st century AD – Hero of Alexandria describes the aeolipile, as an example of the power of heated air or water. The device consists of a rotating ball spun by steam jets; it produced little power and had no practical application, but is nevertheless the first known device moved by steam pressure. He also describes a way of transferring water from one vessel to another using pressure. The methods involved, filling a bucket, the weight of which worked tackle to open temple doors, which were then closed again by a deadweight once the water in the bucket had been drawn out by a vacuum caused by cooling of the initial vessel.
- 1125 In Reims, according to William of Malmesbury, an organ was powered by heated water. –
- 1551 Taqi al-Din Muhammad ibn Ma'ruf describes a steam turbine-like device for rotating a spit. –
- 1601 Giovanni Battista della Porta performs experiments on using steam to create pressure or a vacuum, building simple fountains similar to a percolator. –
- 1606 Jerónimo de Ayanz y Beaumont receives a patent for a steam-powered device for pumping water out of mines. –
- 1615 Salomon de Caus, who had been an engineer and architect under Louis XIII, publishes a book showing a device similar to that of Porta. –
- 1629 Giovanni Branca suggests using a steam turbine device similar to that described by Taqi al-Din but intended to be used to power a series of pestles working in mortars. –
- 1630 David Ramsay is granted a patent for various steam applications, although no description is given and the patent also covers a number of unrelated inventions. He refers to a "fire engine", and this term is used for many years. –
Towards a workable steam engine
- 1663 Edward Somerset, 2nd Marquis of Worcester, publishes a selection of his inventions. One is a new sort of steam pump, essentially two devices like de Caus', but attached to a single boiler. A key invention is the addition of cooling around the containers to force the steam to condense. This produces a partial vacuum inside the chambers, which is used to draw a volume of water into the containers through a pipe, thus forming a pump. He builds one of very large size into the side of Raglan Castle, apparently the first "industrial scale" steam engine. He has plans to build them for mining, but dies before he can set up his company. –
- 1680 Christiaan Huygens publishes memoirs describing a gunpowder engine that drives a piston. It is historically notable as the first known description of a piston engine. –
- 1698 Thomas Savery introduces a steam pump he calls the Miner's Friend. It is almost certainly a direct copy of Somerset's design. One key improvement is added later, replacing the cold water flow on the outside of the cylinder with a spray directly inside it. A small number of his pumps are built, mostly experimental in nature, but like any system based on suction to lift the water, they have a maximum height of 32 feet (and typically much less). In order to be practical, his design can also use the pressure of additional steam to force the water out the top of the cylinder, allowing the pumps to be "stacked", but many mine owners were afraid of the risk of explosion and avoided this option. (Savery engines were re-introduced in the 1780s to recirculate water to water wheels driving textile mills, especially in periods of drought). –
- c. 1705 Thomas Newcomen develops the atmospheric engine, which, unlike the Savery pump, employs a piston in a cylinder; the vacuum pulling the piston down to the bottom of the cylinder when water is injected into it. The engine enabled a great increase in pumping height and the draining of deeper mines than possible when using vacuum to pull the water up. Savery holds a patent covering all imagined uses of steam power, so Newcomen and his partner John Calley persuade Savery to join forces with them to exploit their invention until the expiration of the patent in 1733. –
- 1707 Denis Papin publishes a study on steam power, including a number of ideas. One uses a Savery-like engine to lift water onto a water wheel for rotary power. The study also proposes replacing the water of a Savery engine with a piston, which is pulled on by the vacuum in a cylinder after steam inside is condensed, but he was unable to build the device. –
- 1718 Desaguliers introduces an improved version of the Savery engine, which includes safety valves and a two-way valve that operated both the steam and cold water (as opposed to two separate valves). It is not commercially employed. –
- 1720 Leupold designs an engine based on expansion, which he attributes to Papin, in which two cylinders alternately receive steam and then vent to the atmosphere. Although likely a useful design, it appears none were built. –
The Newcomen Engine: Steam power in practice
- 1712 Newcomen installs his first commercial engine. –
- 1713 Humphrey Potter, a boy charged with operating a Newcomen engine, installs a simple system to automatically open and close the operating valves. The engine can now be run at 15 strokes a minute with little work other than firing the boiler. –
- 1718 Henry Beighton introduces an improved and much more reliable version of Potter's operating system. –
- 1733 Newcomen's patent expires. By this time about 100 Newcomen engines have been built. Over the next 50 years engines are installed in collieries and metal mines all over England, notably in Cornwall, and are also used for municipal water supply and pumping water over water wheels, especially in ironworks. –
- 1755 Josiah Hornblower installs the first commercial Newcomen engine in the USA, at the Schuyler Copper Mine in what is now North Arlington in Bergen County, New Jersey, using parts imported from the UK. –
- 1769 John Smeaton experiments with Newcomen engines, and also starts building improved engines with much longer piston stroke than previous practice. Later engines, which marked probably the high point of Newcomen engine design, deliver up to 80 horsepower (around 60 kW). –
- 1775 By this date about 600 Newcomen engines erected in the UK. –
- 1779 The crank first applied by James Pickard to a Newcomen engine, producing rotary motion. Pickard patents this the following year, but the patent is unenforcable. –
- 1780 Newcomen engines continue to be built in large numbers (about a thousand between 1775 and 1800), especially for mines but increasingly in mills and factories. Many have Watt condensers added after the patent expires (see below). Several dozen improved Savery engines are also built. –
- 1765 James Watt invents the separate condenser, the key being to relocate the water jet, (which condenses the steam and creates the vacuum in the Newcomen engine) inside an additional cylindrical vessel of smaller size enclosed in a water bath; the still-warm condensate is then evacuated into a hot well by means of a suction pump allowing the preheated water to be returned to the boiler. This greatly increases thermal efficiency by ensuring that the main cylinder can be kept hot at all times, unlike in the Newcomen engines where the condensing water spray cooled the cylinder at each stroke. Watt also seals the top of the cylinder so that steam at a pressure marginally above that of the atmosphere can act on top of the piston against the vacuum created beneath it. –
- 1765 Matthew Boulton opens the Soho Manufactory engineering works in Handsworth. –
- 1765 Ivan Polzunov builds a two-cylinder Newcomen engine for powering mine ventilation in Barnaul, Russia. It includes an automated system for governing the water level in the boiler. –
- 1769 James Watt is granted a patent on his improved design. He is unable to find someone to accurately bore the cylinder and is forced to use a hammered iron cylinder. The engine performed poorly, due to the cylinder being out of round, allowing leakage past the piston. However, the increase in efficiency is enough for Watt and his partner Matthew Boulton to license the design based on the savings in coal per year, as opposed to a fixed fee. It would take Watt ten years in total to get an accurately bored cylinder. –
- 1774 John Wilkinson invents a boring machine capable of boring precise cylinders. The boring bar goes completely through the cylinder and is supported on both ends, unlike earlier cantilevered boring tools. Boulton in 1776 writes that "Mr. Wilkinson has bored us several cylinders almost without error; that of 50 inches diameter, which we have put up at Tipton, does not err on the thickness of an old shilling in any part". –
- 1775 Watt and Boulton enter into a formal partnership. Watt's patent is extended by Act of Parliament for 25 years until 1800. –
- 1776 First commercial Boulton and Watt engine built. At this stage and until 1795 B&W only provided designs and plans, the most complicated engine parts, and support with on-site erection. –
- 1781 Jonathan Hornblower patents a two-cylinder "compound" engine, in which the steam pushes on one piston (as opposed to pulling via vacuum as in previous designs), and when it reaches the end of its stroke is transferred into a second cylinder that exhausts into a condenser as "normal". Hornblower's design is more efficient than Watt's single-acting designs, but similar enough to his double-acting system that Boulton and Watt are able to have the patent overturned by the courts in 1799. –
- 1782 First Watt rotative engine, driving a flywheel by means of the sun and planet gear rather than a crank, thus avoiding James Pickard's patent. Watt secures further patents in this year and 1784. –
- 1783 Watt builds his first "double acting" engine, which admits steam so as to alternately act on one side of the piston then on the other, and the introduction of his parallel motion linkage allows the transmission of the power of the piston motion to be transmitted to the beam on both strokes. This change enables use of a flywheel imparting steady rotary motion controlled by a governor, thus making it possible for the engine to drive machinery in non speed critical applications like milling, breweries and other manufacturing industries. Because the centrifugal governor alone had poor response to load changes, Watt's engine was not suitable for cotton spinning. –
- 1784 William Murdoch demonstrates a model steam carriage working on "strong steam". He is dissuaded from patenting his invention by his employer, James Watt. –
- 1788 Watt builds the first steam engine to use a centrifugal governor for the Boulton & Watt Soho factory. –
- 1790 Nathan Read invented the tubular boiler and improved cylinder, devising the high-pressure steam engine. –
- 1791 William Bull makes a seemingly obvious design change by inverting the steam engine directly above the mine pumps, eliminating the large beam used since Newcomen's designs. About 10 of his engines are built in Cornwall. –
- 1795 Boulton and Watt open their Soho Foundry, for the manufacture of steam engines –
- 1799 Richard Trevithick builds his first high-pressure engine at Dolcoath tin mine in Cornwall. –
- 1800 Watt's patent expires. By this time about 450 Watt engines (totaling 7,500 hp) and over 1500 Newcomen engines have been built in the UK. –
- 1801 Richard Trevithick builds and runs Camborne road engine. –
- 1801 Oliver Evans builds his first high-pressure steam engine in the U.S.(Ptd. 1804) –
- 1804 Richard Trevithick builds and runs single-cylinder flywheel locomotive on the 9-mile Pen-y-Darran tramway. Due to plate breakages the engine is installed at Dowlais for stationary use. –
- 1804 John Steel builds locomotive to Trevithick's model at Gateshead for Mr Smith. This is demonstrated to Christopher Blackett who refuses it for reasons of excess weight. –
- 1804 Arthur Woolf re-introduces Hornblower's double-cylinder designs now that Watt's patents have expired. He goes on to build a number of examples with up to nine cylinders as boiler pressures increase through better manufacturing and materials. –
- 1808 Christopher Blackett relays track at Wylam Colliery. –
- 1808 Richard Trevithick demonstrates the passenger carrying railway with his "steam circus" (using the locomotive Catch Me Who Can on a circular track) in London. –
- 1811 Blackett employs Thomas Waters to build a new flywheel locomotive. –
- 1811 Blackett instructs Timothy Hackworth to build hand-cranked chassis to prove feasibility of smooth rail for traction. –
- 1811 Second Wylam locomotive built by Blackett's development team consisting of Timothy Hackworth, William Hedley, and Jonathan Foster. –
- 1812 Blenkinsop develops rack railway system in collaboration with Matthew Murray of Leeds Round Foundry - single-flue boiler; vertical cylinders sunk into boiler. –
- 1813 Third Wylam locomotive built, with 8 wheels to spread axle load. –
- 1815 Blücher - similar to Blenkinsop model. –
- 1825 Robert Stephenson & Co build Locomotion for Stockton and Darlington Railway. –
- 1827 blastpipe in the chimney for Stockton and Darlington Railway. –
- 1829 Robert Stephenson & Co successfully competes at Rainhill Trials with The Rocket against Hackworth's Sans Pareil and Braithwaite's and Ericsson's Novelty. –
- 1830 Stephensonian locomotive configuration appears with Stephenson's Planet type along with Edward Bury's Liverpool - horizontal cylinders placed beneath smokebox; drive to rear crank - bar frames. Liverpool Manchester Line opens with tumultuous acclaim –
- 1849 Corliss-type steam engine, a four-valve counterflow engine with separate steam admission and exhaust valves. Trip valve mechanisms provide sharp cutoff of steam during admission stroke. The governor is used to control the cut off instead of the throttle valve. The efficiency of Corliss engines greatly exceeds other engines of the period, and they are rapidly adopted in stationary service throughout industry. The Corliss engine has better response to changes in load and runs at a more constant speed, making it suitable for applications such as thread spinning. –
- 1854 John Ramsbottom publishes a report on his use of oversized split steel piston rings which maintain a seal by outward spring tension on the cylinder wall. This allows much better sealing (compared to earlier cotton seals) which leads to significantly higher system pressures before "blow-by" is experienced. –
- 1862 The Allen steam engine (later called Porter-Allen) is exhibited at the London Exhibition. It is precision engineered and balanced allowing it to operate at from three to five times the speed of other stationary engines. The short stroke and high speed minimize condensation in the cylinder, significantly improving efficiency. The high speed allows direct coupling or the use of reduced sized pulleys and belting. –
- 1862 The steam engine indicator is exhibited at the London Exhibition. Developed for Charles Porter by Charles Richard, the steam engine indicator traces on paper the pressure in the cylinder throughout the cycle, which can be used to spot various problems and to optimize efficiency. Earlier versions of the steam engine indicator were in use by 1851, though relatively unknown. –
- 1865 Auguste Mouchout invents the first device to convert solar energy into mechanical steam power, using a cauldron filled with water enclosed in glass, which would be put in the sun to boil the water. –
- 1867 Babcock and Wilcox-type boiler designs become popular in new installations. –
- 1881 Alexander C. Kirk designs the first practical triple expansion engine which was installed in SS Aberdeen. –
- 1897 Charles Algernon Parsons patented a steam turbine, which was used to power a ship. The turbine works like a multi-cylinder steam engine, but with any number of "cylinders" in series, built of simple bladed wheels. The efficiency of large steam turbines is considerably better than the best compound engines, while also being much simpler, more reliable, smaller and lighter all at the same time. Steam turbines have replaced piston engines for power generation almost universally since then. –
- 1897 Stanley Brothers begin selling lightweight steam cars, over 200 being made. –
- 1899 The Locomobile Company begins manufacture of the first production steam-powered cars, after purchasing manufacturing rights from the Stanley Brothers. –
- 1902 The Stanley Motor Carriage Company begins manufacture of the Stanley Steamer, the most popular production steam-powered car. –
- 1903 Commonwealth Edison Fisk Generating Station opens in Chicago, using 32 Babcock and Wilcox boilers driving several GE Curtis turbines, at 5000 and 9000 kilowatts each, the largest turbine-generators in the world at that time. Almost all electric power generation, from the time of the Fisk Station to the present, is based on steam driven turbine-generators. –
- 1913 Nikola Tesla patents a bladeless steam turbine that utilizes the boundary layer effect. This design has never been used commercially due to its low efficiency. –
- 1923 Alan Arnold Griffith publishes An Aerodynamic Theory of Turbine Design, describing a way to dramatically improve the efficiency of all turbines. In addition to making newer power plants more economical, it also provides enough efficiency to build a jet engine. –
- 1933 George and William Besler of the United States are the first aviators (and to this date only aviators) to successfully fly on steam power on April 12, 1933 with a converted Travel Air 2000 biplane, using a 90° V-twin compound engine of their own design. –
- 2009 On August 25, 2009, Team Inspiration of the British Steam Car Challenge broke the long-standing record for a steam vehicle set by a Stanley Steamer in 1906, setting a new speed record of 139.843 mph in the Edwards Air Force Base, in the Mojave Desert of California. –
