History edit

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]

Notes edit

  1. ^ The oldest working engine, the Smethwick Engine, and the second oldest, the Whitbread Engine, are beam engines, and neither uses a hypocycloidal straight line mechanism.
