Jessop-Saville
Special Steels producer, of Brightside Works, Brightside Lane, Sheffield.
1929 BSA merged its steelmaking subsidiaries William Jessop and Sons and J. J. Saville and Co to form Jessop-Saville.
WWII The company was an important supplier of austenitic steel for the manufacture of aero engine valves. The company also produced vast numbers of ball bearing housing rings and other forgings for the war effort.
1959 the three companies in BSA’s steel group, namely William Jessop and Sons Ltd, J. J. Saville and Co Ltd., and Bromley, Fisher and Turton Ltd., all of Sheffield, were consolidated into two new companies, Jessop-Saville Limited and Jessop-Saville (Small Tools) Limited. [1] The latter manufactured carbide tipped and welded steel tools.
1963 On 12 Apr an explosion of a titanium furnace occured at the works. An investigation was carried out and reported on by the Royal Aeronautical Establishment. Injuries were relatively minor despite there being nearly 30 people working in the area.[2]
1967 Edgar Allen and Co purchased Jessop's foundry interests[3], relocating Jessop's special alloy (medium frequency) melting plant to Edgar's Sheffield Road site and the 3-ton electric furnace was moved to one end of the Tropenas Melting Shop.
1967 One of the larger steel makers not subject to nationalisation[4]
1967 – Thomas Firth and John Brown Limited acquire Jessop-Saville Limited from BSA for £3,328,000. At about the same time, Imperial Metal Industries acquired the titanium business. [5]
