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 Tusi couple hypocycloidal straight line mechanism.^[a]

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. Hingley & Sons Ltd 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]
