and mill machinery. It supplied machinery "on a new and perfectly unique" concept together with iron pillars, roofing and fittings for the steam-driven pulp and paper mill at Woolwich Arsenal in 1856. The mill made cartridge bags at the rate of about 20,000 per hour, sufficient to supply the entire British army and navy. The intention was to manufacture paper for various departments of Her Majesty's service. Steel boilers were first produced in 1863, mostly of the Lancashire type, and more than 200 locomotive boilers were made for torpedo boats into the 1890s. The Phoenix Boiler Works were purchased in 1891 to meet an increase in demands. Bolton Steam Museum hold a 1906 Hick, Hargreaves and Co. Ltd. Lancashire boiler front-plate, previously installed at Halliwell Mills, Bolton. The company introduced the highly efficient Corliss valve gear into the United Kingdom from the United States in about 1864 and was closely identified with it thereafter; William Inglis being responsible for promoting the high speed Corliss engine. About 1881 Hick, Hargreaves received orders for two Corliss engines of 3000 hp, the largest cotton mill engines in the world. Hargreaves and Inglis trip gear was first applied to a large single cylinder 1800 hp Corliss engine at Eagley Mills near Bolton and the company received a Gold Medal for its products at the 1885 International Inventions Exhibition. An 1886 Hick, Hargreaves and Co. inverted, vertical single cylinder Corliss engine with Spencer Inglis valve gear, used to run Ford Ayrton and Co.'s spinning mill, Bentham until 1966 is preserved under glass at Bolton Town Centre. Mill gearing was a speciality including large flywheels for rope drives, one example of 128 tons being 32 ft in diameter and groved for 56 ropes. Turbines and hydraulic machinery were also manufactured. Many of the tools were to suit the specialist work, with travelling cranes to take 15 to 40 tons in weight, a large lathe, side planer, slotting machine, pit planer and a tool for turning four 32 ft rope flywheels simultaneously. The workshops also featured an 80ton hydraulic riveting machine. For the ease of shipping and transportation, Soho Iron Works had its own railway system, traversed by sidings of the London North Western Railway (LNWR). Inglis, who lived in Bolton was a neighbour of LNWR's chief mechanical engineer, Francis Webb. The company was renamed Hick, Hargreaves and Company in 1867; John Hick retired from the business
