1835-1933, boilermaker and engineer, Manchester. Engineering firm Galloway, Bowman and Glasgow was established in Lancashire in 1790 by William Galloway. The business had an iron foundry, and also manufactured mill wheels. In 1836, following the death of William Galloway, his sons William and John Galloway left the company and established their own firm, W. and J. Galloway at Knott Mill Ironworks. The company became W. and J. Galloway and sons in 1856, and became a private company, Galloways Ltd in 1889. In 1899 Galloways became a private limited company. The business became one of the leading suppliers of steam boilers to mills and factories in the Manchester area, but the firm manufactured a range of other metal goods. These included rivets, screw jacks, pipes, axels and wagons for railways and planing machinery. In 1848 the company patented their double-fire flue boiler, known as the Galloway Boiler. This would become the firm's best-known product. By the 1850s and 1860s the firm had a diverse international business. This included the supply of gunpowder mills and steam engines to powder mills in Constantinople, steam engines and gearings for Russian cotton mills around St. Petersburg area, and machinery for Indian-based cotton mills. The company was also engaged in civil engineering projects, notably building a viaduct for the Ulverston and Lancaster Railway in 1855-1857 and Southport Pier in 1859-1860. In 1856 Charles and John Galloway, became partners in the family business. Charles would become its Chairman in 1889. At its peak, Galloways employed more than 1,000 people. Galloways ceased trading and went into receivership in 1932. The firm's records, drawings and patterns were purchased by Hick, Hargreaves & Co. of Bolton in 1933.

Sir W H Bailey & Co Ltd came into existence in 1913, following the death of Sir William H Bailey, owner of the company under its previous name W H Bailey & Co. The company dates back to 1839, with the establishment of John Bailey's clock making business at Albion Works in Salford. By 1863, the business was known as John Bailey & Co, and is listed in the Slater's Trade Directory as turret clock makers, brassfounders, steam and water gauge makers, and copying press makers. Sir William H Bailey was the son of John Bailey and took over the running of the business in 1865 under the name John Bailey & Co. From 1865, the company focused on the manufacture of steam related machinery and equipment, including valves, gauges, lifts, hoists, steam pumps, injectors and boiler fittings. By 1879, the company advertised itself as hydraulic engineers, alongside its existing interests. In 1885 a new works opened at Hall Bank, Patricroft. In 1889, the business became a private limited company known as W H Bailey & Co Ltd, Hydraulic Engineers, Brassfounders, Machinists and manufacturers and merchants of all kinds of tools, plant, and instruments. Ten years later, the company expanded to include additional premises in Salford for the manufacture of motorcar engines. Sir William H Bailey's son Alfred Bailey became the governing director of the renamed company in 1918. Another son, Frederick, became managing director the same year. Frederick was chairman of the company in 1940, succeeding his brother Alfred. The original Albion works were closed and demolished that same year, with all manufacturing moving to the Patricroft site. In 1966, Sir William H Bailey & Co Ltd became a subsidiary of Yorkshire Imperial Metals, continuing to operate under its own name, as it did after a merger with another subsidiary company, Whites-Nunan Ltd, the following year. The works at Patricroft were retained as a foundry and manufacturing site. The company name survived until 1978, when it became known as IMI Bailey Valves Limited.
