Yates & Thom Ltd, or Yates of Blackburn, was a British manufacturer of stationary steam engines and boilers at the Canal Ironworks, Blackburn, Lancashire, England.
The company had its origins in a blacksmith's shop started by William Yates in 1824.[1]
In the 1860s, the company supplied a cam operated, drop valve compound engine operating at 100psi to the India Mill, Darwen.[2] Other mills supplied by Yates and Thom included the Durban Mill, Oldham. This was 1800 hp triple-expansion four-cylinder engine built in 1906. It had a 24"HP, 29"IP, two 38"LP cylinders with a 5ft 6" stroke. At 180psi, it drove a. 27ft, 67 ton flywheel with 38 ropes, at 65 rpm. It used Corliss valves on all cylinders.[3]
The company supplied a 3,300 horse power twin tandem compound engine which survives in the engine house at the Astley Green Colliery Museum and was the largest steam winding engine used on the Lancashire Coalfield.[4]
In later years the company was known as Foster, Yates and Thom and continued to manufacture boilers until 1964. The remainder of the works closed in 1973.[1]
