A Watt engine: showing entry of steam and water. A beam engine is a type of steam engine where a pivoted overhead beam is used to apply the force from a vertical piston to a vertical connecting rod. This configuration, with the engine directly driving a pump, was first used by Thomas Newcomen around 1705 to remove water from mines in Cornwall.
An illustration of Hero's aeolipile. An aeolipile, aeolipyle, or eolipile, from the Greek "Αἰόλου πύλη," lit. ' Aeolus gate ', also known as a Hero's (or Heron's) engine, is a simple, bladeless radial steam turbine which spins when the central water container is heated.
The engine was later described as being of 30 hp in power. [11] The beam was typical for early single-acting beam engines, pulling through wrought iron chains running over a curved arch-head at each end of the beam. At some later point, possibly when reconstructed after the fire, this beam was strengthened by being strutted and bridled with the ...
The speed of each power stroke or 'coming indoors' was a feature of the engine and was not easily varied, but there was no need for the engines to run continuously, stroke after stroke. [4] [6] This was a direct contrast to the rotative beam engine, and the rotary nature of almost all other steam engines. With the original Newcomen cycle, the ...
Beam engine in 1982. The engine was built in 1833, using parts, including the beam, from a Boulton and Watt engine supplied to Hadden's Aberdeen factory in 1805. [6] The engine has a single vertical cylinder with an 18-inch bore. Steam acts on both sides of the piston and is controlled by a slide valve assembly on the side of the cylinder.
1790 (): Nathan Read invented the tubular boiler and improved cylinder, devising the high-pressure steam engine. 1791 (): Edward 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.

A water-returning engine was an early form of stationary steam engine, developed at the start of the Industrial Revolution in the middle of the 18th century. The first beam engines did not generate power by rotating a shaft but were developed as water pumps , mostly for draining mines .
