Thomas Newcomen, English engineer C017 / 7122
Thomas Newcomen (1664-1729), English engineer, with a diagram of his atmospheric engine of 1712. Newcomen was an ironmonger from Dartmouth, and also a Baptist lay preacher. The Newcomen atmospheric engine was the first to have a walking beam pivoted arm (top) to transfer power between the piston and the rod. It was used to pump water out of coal mines. The piston was driven down by the pressure of a partial vacuum in the cylinder, causing the rod to be drawn upwards. As steam in the cylinder condensed the piston was forced up, and the rod forced down. This was the first true steam engine, widely used over the next 75 years

EDITORS COMMENTS
This print showcases the brilliant mind of Thomas Newcomen, an English engineer and pioneer of the industrial revolution. In this portrait, we see a distinguished-looking man with a diagram of his groundbreaking invention, the atmospheric engine of 1712. Newcomen's remarkable creation revolutionized coal mining by efficiently pumping water out of mines. The ingenuity behind Newcomen's atmospheric engine lies in its walking beam pivoted arm, visible at the top of the diagram. This innovative design allowed for seamless power transfer between the piston and rod, enabling effective water extraction from deep underground. The engine operated through a clever interplay between steam condensation and pressure differentials within the cylinder. Newcomen himself was not only an ironmonger hailing from Dartmouth but also a Baptist lay preacher. His unwavering dedication to both engineering and faith is evident in this artwork capturing his likeness. As we delve into history through this illustration, it becomes clear that Newcomen's atmospheric engine marked a turning point in technological advancement during the 18th century. Its impact reverberated throughout England and beyond for over seven decades as it became widely adopted as one of humanity's first true steam engines. Gary Brown's masterful portrayal beautifully encapsulates this significant moment in time when human ingenuity merged with industrial progress. It serves as a testament to Thomas Newcomen's enduring legacy as an inventor whose contributions laid the foundation for future advancements in machinery and engineering practices.
