'''Hathorn Davey''' was a Leeds-based manufacturor of steam engines. The Sun foundry was established in 1846 and made railway engines and pumping machinery until 1870. The premises were taken over in 1872 by Hugh Campbel, Alfred Davis and John Hathorn. They were joined by Henry Davey in 1873 and traded as Hathorn, Davey & Co from 1880. They made marine engines and pumps as well as their pumping engines for mines and waterworks. The firm was taken over by [[Sulzer]]s in 1936. The premises closed in the late 1970s when Sulzers moved to a new site. |

Hathorn Davey was a Leeds-based manufacturor of steam engines. The Sun foundry was established in 1846 and made railway engines and pumping machinery until 1870. The premises were taken over in 1872 by Hugh Campbel, Alfred Davis and John Hathorn. They were joined by Henry Davey in 1873 and traded as Hathorn, Davey & Co from 1880. They made marine engines and pumps as well as their pumping engines for mines and waterworks. The firm was taken over by Sulzers in 1936. The premises closed in the late 1970s when Sulzers moved to a new site.
The horizontal compound differential pumping engine
This was one of their more successful engines. Patented in 1871, a company brochure lists 46 examples of these large engines built up to 1906. The leaflet also gives 32 examples where a smaller version of this engine was installed underground. The differential was a small engine resembling a boiler feed pump which was used to control the speed of the larger engine. [1]The largest concentration of this design was at the Tasmania Gold Mining Co's Beaconsfield mine where three engines were assembled. Each had cylinders of 50 and 108 inch diameter and raised 100,000 galons of water per hour from 2000 ft. Each engine drove two pumprods, each weighing 170 tons and driving 6 pumps. Beaconsfield mine closed in 1914 when the pumps where overwhelmed. It re-opened in 1999. At least 7 of these engines were used in the Furness iron mines, 3 at Yarlside and the remainder at Harrison Ainslie's pits. There is a surviving example at Cambridge Museum of Technology
