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.
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.

Among his most notable contributions to Model Engineer were constructional series detailing models of steam engines dating from the Industrial Revolution: A Vertical Columnar Engine. A model of the "Williamson" engine (serialised in 1976) Mary, a four-column beam engine (serialised in 1977) Lady Stephanie, six-column tank-bed beam engine [4]
An oscillating cylinder engine cannot be reversed by means of the valve linkage (as in a normal fixed cylinder) because there is none. Reversing of the engine can be achieved by reversing the steam connections between inlet and exhaust or, in the case of small engines, by shifting the trunnion pivot point so that the port in the cylinder lines up with a different pair of ports in the port face.
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 ...
The Newcomen Memorial Engine (sometimes called the Coventry Canal Engine) is a preserved beam engine in Dartmouth, Devon. It was preserved as a memorial to Thomas Newcomen (d. 1729), inventor of the beam engine, who was born in Dartmouth. The engine is the world's oldest surviving steam engine. [1]
