The Newcomen steam engine by Jason Crawford · April 2, 2017 · 2 min read After A Culture of Growth, I turned back to my original idea of studying the history of the Industrial Revolution. I’ve picked up the book A Brief History of How the Industrial Revolution Changed the World, by Thomas Crump. The first story of the Industrial Revolution is that of the steam engine. When you think “steam engine”, you may think of James Watt, but the first steam engine was actually created by Thomas Newcomen, in 1712. The Newcomen engine was not an engine the way we think of engines today: as a kind of motor, turning a shaft or crank. It was a pump. And its original use was to pump water out of mines. “Old Bess,” an early steam engine, at the London Science Museum The British iron industry at the time needed a new fuel. Ironmaking requires intense heat and therefore fire. For a long time this was provided by wood (actually by charcoal—but that’s a story for another post). But Britain was rapidly depleting its forests. So, they needed a new fuel, and they turned to coal, which they had plenty of. The problem was that once you go down far enough in a mine, you hit groundwater, and you need to pump it out. In copper or tin mines, the pump was powered by horses. But coal was needed in vaster quantities, requiring larger volumes of water to be pumped. A better source of motive power was needed. Enter the Newcomen engine—a steam engine, although it was also known as an atmospheric engine or a “...

Steam engines are mechanisms that use heat to create steam, which in turn performs mechanical processes, known generally as work. While several inventors and innovators worked on various aspects of using steam for power, the major development of early steam engines involves three inventors and three principal engine designs. 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. However, because Savery's held a broad patent on his own steam pump, Newcomen had to collaborate with Savery to patent the piston pump. Later Steam Engines The early 19th century saw major innovation of high-pressure steam engines, which were much more efficient than the low-pressure designs of Watt's and the others steam-engine pioneers. This led to the development of much smaller, more powerful steam engines that could be used to power trains and boats and to perform a wider range of industrial tasks, such as running saws in mills. Two important innovators of these engines were American Oliver Evans and Englishman Richard Trevithick. Over time, steam engines were replaced by the internal combustion engine for most types of locomotion and industrial work, but the use of steam generators to create electricity remains an important part of electrical power production today.

His engine utilised a piston working within an open topped cylinder. The piston is connected by chains to a rocking beam. At the other end, the beam is connected to the pumps in the mine by a rod. On the outboard stroke, the cylinder is filled with steam from the boiler and then cold water is injected into the cylinder to change the steam back to water and create a vacuum (when water turns to steam it expands 1500 times, so a contained volume of steam, if condensed back to water, will create a vacuum). The vacuum then pulls the piston down and, via the rocking beam, raises the plunger in the water pump. The diagram shows this principal in action. Steam is show as pink and water as blue. The valves move from closed (red) to open (green). The Caprington Colliery opened in the mid-seventeenth century and constantly had problems with drainage as it was located in the low-lying Irvine valley. The Carron Company, Falkirk, first supplied parts for a Newcomen Engine to Sir William Cunninghame of Caprington in 1781, but the pumping shaft collapsed in 1828 and that mine was subsequently abandoned. Despite having a poorer fuel efficiency than a The engine was erected on a site near Earlston. One of its component parts, a knee pipe bearing the inventory number N1708, was recycled from the original 1781 engine. The new engine drained the Blind Coal seam at a depth of 50 metres and worked continuously for ninety years, with a replacement cast iron beam in c.1837 and several new boilers....

1. A Man of Many Talents Thomas Newcomen was a man of many talents. Not only was he a successful inventor, but he was also a preacher and teaching elder in the Baptist church. He served in this capacity until 1710, when he was appointed pastor of the church. During his time as a preacher, he was known for his passionate sermons and his dedication to his congregation. He was a beloved figure in the church, and his appointment as pastor was a testament to his commitment to the faith. 2. Newcomen Society displays working model of Thomas Newcomen's engine In 1964, the Newcomen Society displayed one of Thomas Newcomen's engines as a working model, powered by hydraulics instead of a steam boiler. This was a significant milestone in the history of the Newcomen Society, as it was the first time one of Newcomen's engines had been displayed in a working state since the 18th century. The engine was a testament to Newcomen's engineering genius, and the Society's dedication to preserving his legacy. 3. Thomas Newcomen's Revolutionary Steam Engine Revolutionized Mining By the early 1700s, Thomas Newcomen's revolutionary steam engine had become a staple of the mining industry. By 1733, the engine had been installed in at least 125 mining districts across the world, revolutionizing the way coal and other minerals were extracted from the earth. This invention allowed miners to access resources that were previously inaccessible, and it drastically increased the efficiency of the mining proc...

The Watt steam engine design became synonymous with steam engines, and it was many years before significantly new designs began to replace the basic Watt design. The Watt realised that the heat needed to warm the cylinder could be saved by adding a separate condensing cylinder. After the power cylinder was filled with steam, a valve was opened to the secondary cylinder, allowing the steam to flow into it and be condensed, which drew the steam from the main cylinder causing the power stroke. The condensing cylinder was water cooled to keep the steam condensing. At the end of the power stroke, the valve was closed so the power cylinder could be filled with steam as the piston moved to the top. The result was the same cycle as Newcomen's design, but without any cooling of the power cylinder which was immediately ready for another stroke. Watt worked on the design over a period of several years, introducing the condenser, and introducing improvements to practically every part of the design. Notably, Watt performed a lengthy series of trials on ways to seal the piston in the cylinder, which considerably reduced leakage during the power stroke, preventing power loss. All of these changes produced a more reliable design which used half as much coal to produce the same amount of power. The new design was introduced commercially in 1776, with the first example sold to the Introduction [ ] In 1698, the English mechanical designer The solution to draining deep mines was found by The ...

Vintage engraving of Newcomen atmospheric engine. The atmospheric engine was invented by Thomas Newcomen in 1712, and is often referred to simply as a Newcomen engine. The engine was operated by condensing steam drawn into the cylinder, thereby creating a partial vacuum which allowed the atmospheric pressure to push the piston into the cylinder.

In the technology-themed winter 2021 edition of The ‘demonstrable and inalienable fact’ to which Winchester refers leads inexorably to James Watt, the Scottish inventor and mechanical engineer, born in Greenock, near Glasgow, on 18 January 1736. An Winchester adds: “The Industrial Revolution is thus wholly indebted to Watt: no more seminal device than his engine and its countless derivatives would be born for almost two centuries”. Watt was an innovator who saw the flaws in previous steam-powered engines and came up with vital improvements. Before him, there had been several attempts at constructing an effective machine. One in particular, developed in Britain by Thomas Newcomen in the early 1700s, had been in widespread use driving pumps to remove water from mines, which was one of the biggest industrial challenges of the 18th century. In 1763, Watt, employed by the University of Glasgow as a maker of precision tools and instruments, was asked to examine a Newcomen engine. These were “extremely inefficient” energy-wasting machines, says Carl Lira, an associate professor in the School of Engineering...

The first practical mechanical steam engine was introduced by plug tree suspended from the rocking beam which rendered the engine self-acting. A number of Newcomen engines were successfully put to use in Britain for draining hitherto unworkable deep mines, with the engine on the surface; these were large machines, requiring a lot of capital to build, and produced about 5hp. They were extremely inefficient by modern standards, but when located where coal was cheap at pit heads, opened up a great expansion in James Watt's steam engines [ ] Main article: A fundamental change in working principles was brought about by The Newcomen engine could not, at the time, be easily adapted to drive a rotating wheel, although Wasborough and Pickard did succeed in doing so in about 1780. However, by 1783 the more economical Watt steam engine had been fully developed into a double-acting rotative type with a By 1800, the firm Development after Watt [ ] See also: The development of In the early 19th century, after the expiration of the Boulton & Watt patent in 1800, the steam engine underwent great increases in power due to the use of higher-pressure steam, which Watt had always avoided because of the danger of exploding boilers, which were in a very primitive state of development. Until about 1800, the most common pattern of steam engine was the Trevithick was a man of versatile talents, and his activities were not confined to small applications.
