William McNaught
Edit ProfileCareer
William McNaught was a steam engine engineer from Rochdale, Lancashire, England. He then worked in London for John & Thomas Rennie before coming to Alexander Petrie & Son, around 1838. McNaught became chief designer and superintendent at James Petrie"s and designed a cutoff gear for use on a stationary steam engine. This was patented by James Petrie in 1844.
Petrie started to build mill engines in 1819, McNaught joined in 1838 and remained until 1858, when he started his own company. Before this patent, there were problems with slide valves which suffered excessive wear.
The Petrie and McNaught cutoff valves were circular with sloping faces that allowed a variable cut-official They could be easily connected to the governor that McNaught patented in 1850.
In 1860 he left Petrie"s to set up his own business building steam engines at the former Halstead"s "Union Foundry" at Wet Rake on Drake Street, Rochdale.
He was so successful that by 1863 he had built the Street George"s Foundry on Crawford Saint Rochdale. They later amalgamated with John Petrie becoming Petrie and McNaught.
Connections
He had two sons, John and William.
