14 Cort, Henry
SUBJECT AREA: Metallurgy[br]b. 1740 Lancaster, Englandd. 1800 Hampstead, near London, England[br]English ironmaster, inventor of the puddling process and grooved rollers for forming iron into bars.[br]His father was a mason and brickmaker but, anxious to improve himself, Cort set up in London in 1765 as a navy agent, said to have been a profitable business. He recognized that, at that time, the conversion of pig iron to malleable or wrought iron, which was needed in increasing quantities as developments in industry and mechanical engineering gathered pace, presented a bottleneck in the ironmaking process. The finery hearth was still in use, slow and inefficient and requiring the scarce charcoal as fuel. To tackle this problem, Cort gave up his business and acquired a furnace and slitting mill at Fontley, near Fareham in Hampshire. In 1784 he patented his puddling process, by which molten pig iron on the bed of a reverberatory furnace was stirred with an iron bar and, by the action of the flame and the oxygen in the air, the carbon in the pig iron was oxidized, leaving nearly pure iron, which could be forged to remove slag. In this type of furnace, the fuel and the molten iron were separated, so that the cheaper coal could be used as fuel. It was the stirring action with the iron bar that gave the name "puddling" to the process. Others had realized the problem and reached a similar solution, notably the brothers Thomas and George Cranage, but only Cort succeeded in developing a commercially viable process. The laborious hammering of the ball of iron thus produced was much reduced by an invention of the previous year, 1783. This too was patented. The iron was passed between grooved rollers to form it into bars. Cort entered into an agreement with Samuel Jellico to set up an ironworks at Gosport to exploit his inventions. Samuel's father Adam, Deputy Paymaster of the Navy, advanced capital for this venture, Cort having expended much of his own resources in the experimental work that preceded his inventions. However, it transpired that Jellico senior had, unknown to Cort, used public money to advance the capital; the Admiralty acted to recover the money and Cort lost heavily, including the benefits from his patents. Rival ironmasters were quick to pillage the patents. In 1790, and again the following year, Cort offered unsuccessfully to work for the military. Finally, in 1794, at the instigation of the Prime Minister, William Pitt the Younger, Cort was paid a pension of £200 per year in recognition of the value of his improvements in the technology of ironmaking, although this was reduced by deductions to £160. After his death, the pension to his widow was halved, while some of his children received a pittance. Without the advances made by Cort, however, the iron trade could not have met the rapidly increasing demand for iron during the industrial revolution.[br]Bibliography1787, A Brief State of Facts Relative to the New Method of Making Bar Iron with Raw Pit Coal and Grooved Rollers (held in the Science Museum Library archive collection).Further ReadingH.W.Dickinson, 1941, "Henry Cort's bicentary", Transactions of the Newcomen Society 21: 31–47 (there are further references to grooved rollers and the puddling process in Vol. 49 of the same periodical (1978), on pp. 153–8).R.A.Mott, 1983, Henry Con, the Great Finery Creator of Puddled Iron, Sheffield: Historical Metallurgy Society.LRD -
15 Wilson, Thomas
[br]b. 1781 Dunbar, Scotlandd. 1 December 1873 Grangemouth, Scotland[br]Scottish shipwright and canal engineer, builder of the barge Vulcan, the world's first properly constructed iron ship.[br]Wilson, the son of a sailor, spent his early years on the Forth. Later his father moved home to the west and Wilson served his apprenticeship as a shipwright on the Clyde at the small shipyards of Bowling, fifteen miles (24 km) west of Glasgow and on the river's north bank. In his late thirties Wilson was to take the leading role in what is arguably the most important development in Scotland's distinguished shipbuilding history: the building of the world's first properly constructed iron ship. This ship, the Vulcan, was the culmination of several years' effort by a group of people well connected within the academic establishment of Scotland. The Forth and Clyde Canal Company had passed instructions for investigations to be made into reducing running expenses and a distinguished committee looked into this matter. They included John Robison (Secretary of the Royal Society of Edinburgh), Professor Joseph Black of Glasgow University, James Watt and John Schanck. After a period of consideration it was decided to build a new, fastpassage barge of iron, and tenders were invited from several appropriate contractors. Wilson, with the assistance of two blacksmiths, John and Thomas Smellie, was awarded the work, and the Vulcan was constructed and ultimately launched at Faskine near Glasgow in 1819. The work involved was far beyond the comprehension of engineers of the twentieth century, as Wilson had to arrange puddled-iron plates for the shell and hand-crafted angle irons for the frames. His genius is now apparent as every steel ship worldwide uses a form of construction literally "hammered out on the anvil" between 1818 and 1819. The Vulcan was almost 64 ft (19.5 m) in length and 11 ft (3.4 m) broad. In 1822 Wilson was appointed an inspector of works for the Canal Company, and ultimately he superintended the building of the docks at Grangemouth, where he died in 1873, the same year that the Vulcan was broken up.[br]Further ReadingR.Harvey, 1919, Early Days of Engineering in Glasgow, Glasgow: Aird and Coghill.

20 Kirkaldy, David
[br]b. 4 April 1820 Mayfield, Dundee, Scotlandd. 25 January 1897 London, England[br]Scottish engineer and pioneer in materials testing.[br]The son of a merchant of Dundee, Kirkaldy was educated there, then at Merchiston Castle School, Edinburgh, and at Edinburgh University. For a while he worked in his father's office, but with a preference for engineering, in 1843 he commenced an apprenticeship at the Glasgow works of Robert Napier. After four years in the shops he was transferred to the drawing office and in a very few years rose to become Chief. Here Kirkaldy demonstrated a remarkable talent both for the meticulous recording of observations and data and for technical drawing. His work also had an aesthetic appeal and four of his drawings of Napier steamships were shown at the Paris Exhibition of 1855, earning both Napier and Kirkaldy a medal. His "as fitted" set of drawings of the Cunard Liner Persia, which had been built in 1855, is now in the possession of the National Maritime Museum at Greenwich, London; it is regarded as one of the finest examples of its kind in the world, and has even been exhibited at the Royal Academy in London.With the impending order for the Royal Naval Ironclad Black Prince (sister ship to HMS Warrior, now preserved at Portsmouth) and for some high-pressure marine boilers and engines, there was need for a close scientific analysis of the physical properties of iron and steel. Kirkaldy, now designated Chief Draughtsman and Calculator, was placed in charge of this work, which included comparisons of puddled steel and wrought iron, using a simple lever-arm testing machine. The tests lasted some three years and resulted in Kirkaldy's most important publication, Experiments on Wrought Iron and Steel (1862, London), which gained him wide recognition for his careful and thorough work. Napier's did not encourage him to continue testing; but realizing the growing importance of materials testing, Kirkaldy resigned from the shipyard in 1861. For the next two and a half years Kirkaldy worked on the design of a massive testing machine that was manufactured in Leeds and installed in premises in London, at The Grove, Southwark.The works was open for trade in January 1866 and engineers soon began to bring him specimens for testing on the great machine: Joseph Cubitt (son of William Cubitt) brought him samples of the materials for the new Blackfriars Bridge, which was then under construction. Soon The Grove became too cramped and Kirkaldy moved to 99 Southwark Street, reopening in January 1874. In the years that followed, Kirkaldy gained a worldwide reputation for rigorous and meticulous testing and recording of results, coupled with the highest integrity. He numbered the most distinguished engineers of the time among his clients.After Kirkaldy's death, his son William George, whom he had taken into partnership, carried on the business. When the son died in 1914, his widow took charge until her death in 1938, when the grandson David became proprietor. He sold out to Treharne \& Davies, chemical consultants, in 1965, but the works finally closed in 1974. The future of the premises and the testing machine at first seemed threatened, but that has now been secured and the machine is once more in working order. Over almost one hundred years of trading in South London, the company was involved in many famous enquiries, including the analysis of the iron from the ill-fated Tay Bridge (see Bouch, Sir Thomas).[br]Principal Honours and DistinctionsInstitution of Engineers and Shipbuilders in Scotland Gold Medal 1864.Bibliography1862, Results of an Experimental Inquiry into the Tensile Strength and Other Properties of Wrought Iron and Steel (originally presented as a paper to the 1860–1 session of the Scottish Shipbuilders' Association).Further ReadingD.P.Smith, 1981, "David Kirkaldy (1820–97) and engineering materials testing", Transactions of the Newcomen Society 52:49–65 (a clear and well-documented account).LRD / FMW
