James Howden and Co Ltd. of 195, Scotland-Street, Glasgow.
1854 James Howden set up in business as a consulting engineer and designer.
1857 Howden began to design and supply boilers and steam engines for the marine industry.
1860 Howden patented a method of preheating combustion air.
1862, in partnership with James Mathie, Howden purchased land at Scotland Street on the south side of Glasgow, and established the firm of James Howden and Co to manufacture engines and boilers.
1863 Introduced a furnace mechanical draught system using a steam turbine-driven axial flow fan.
1882 Howden patented the "Howden System of Forced Draught" which combined mechanical draught with the transfer of heat from the flue gases to the combustion air.
Shipbuilding was later added to the firm's activities, although the work of hull building was contracted out.
1889 See 1889 Shipbuilding Statistics for detail of the marine engines produced
By 1900 The company was making high-speed engines of the enclosed, forced-lubrication type, which were used chiefly for generating electricity.
1904 Howden began to manufacture steam turbines for use in power generation.
These were followed by the Howden Zoelly impulse type of steam turbine, which the firm supplied to many municipalities, including an installation for the corporation of Manchester.
