Murray's Hypocycloidal Engine, now in Thinktank, Birmingham Science Museum, England, was made around 1805[1] and is the world's third-oldest working steam engine[2] and the oldest working engine with a hypocycloidal gear.[1]


The engine in motion

Designed by Matthew Murray, and made by Fenton, Murray and Wood of Holbeck, Leeds, it is one of only two of the type to survive;[3] the other is located at The Henry Ford, Michigan, United States.[4]

The single-cylinder engine was used by John Bradley & Co of Stourbridge from 1805 until 1931, and by N Hingkey & Sons of Netherton from 1931 until 1961, when it was acquired by Birmingham City Council for their science museum.[5]

Murray patented the hypocycloidal arrangement in 1802.[3]
