5 Clerke, Sir Clement
SUBJECT AREA: Metallurgy[br]d. 1693[br]English entrepreneur responsible, with others, for attempts to introduce coal-fired smelting of lead and, later, of copper.[br]Clerke, from Launde Abbey in Leicestershire, was involved in early experiments to smelt lead using coal fuel, which was believed to have been located on the Leicestershire-Derbyshire border. Concurrently, Lord Grandison was financing experiments at Bristol for similar purposes, causing the downfall of an earlier unsuccessful patented method before securing his own patent in 1678. In that same year Clerke took over management of the Bristol works, claiming the ability to secure financial return from Grandison's methods. Financial success proved elusive, although the technical problems of adapting the reverberatory furnace to coal fuel appear to have been solved when Clerke was found to have established another lead works nearby on his own account. He was forced to cease work on lead in 1684 in respect of Grandison's patent rights. Clerke then turned to investigations into the coal-fired smelting of other metals and started to smelt copper in coal-fired reverberatory furnaces. By 1688–9 small supplied of merchantable copper were offered for sale in London in order to pay his workers, possibly because of further financial troubles. The practical success of his smelting innovation is widely acknowledged to have been the responsibility of John Coster and, to a smaller extent, Gabriel Wayne, both of whom left Clerke and set up separate works elsewhere. Clerke's son Talbot took over administration of his father's works, which declined still further and closed c. 1693, at about the time of Sir Clement's death. Both Coster and Wayne continued to develop smelting techniques, establishing a new British industry in the smelting of copper with coal.[br]Principal Honours and DistinctionsCreated baronet 1661.Further ReadingRhys Jenkins, 1934, "The reverberatory furnace with coal fuel", Transactions of the Newcomen Society 34:67–81.—1943–4, "Copper smelting in England: Revival at the end of the seventeenth century", Transactions of the Newcomen Society 24:78–80.J.Morton, 1985, The Rise of the Modern Copper and Brass Industry: 1690 to 1750, unpublished PhD thesis, University of Birmingham, 87–106.JD -

7 Barber, John
[br]baptized 22 October 1734 Greasley, Nottinghamshire, Englandd. 6 November 1801 Attleborough, Nuneaton, England[br]English inventor of the gas turbine and jet propulsion.[br]He was the son of Francis Barber, coalmaster of Greasley, and Elizabeth Fletcher. In his will of 1765. his uncle, John Fletcher, left the bulk of his property, including collieries and Stainsby House, Horsley Woodhouse, Derbyshire, to John Barber. Another uncle, Robert, bequeathed him property in the next village, Smalley. It is clear that at this time John Barber was a man of considerable means. On a tablet erected by John in 1767, he acknowledges his debt to his uncle John in the words "in remembrance of the man who trained him up from a youth". At this time John Barber was living at Stainsby House and had already been granted his first patent, in 1766. The contents of this patent, which included a reversible water turbine, and his subsequent patents, suggest that he was very familiar with mining equipment, including the Newcomen engine. It comes as rather a surprise that c.1784 he became bankrupt and had to leave Stainsby House, evidently moving to Attleborough. In a strange twist, a descendent of Mr Sitwell, the new owner, bought the prototype Akroyd Stuart oil engine from the Doncaster Show in 1891.The second and fifth (final) patents, in 1773 and 1792, were concerned with smelting and the third, in 1776, featured a boiler-mounted impulse steam turbine. The fourth and most important patent, in 1791, describes and engine that could be applied to the "grinding of corn, flints, etc.", "rolling, slitting, forging or battering iron and other metals", "turning of mills for spinning", "turning up coals and other minerals from mines", and "stamping of ores, raising water". Further, and importantly, the directing of the fluid stream into smelting furnaces or at the stern of ships to propel them is mentioned. The engine described comprised two retorts for heating coal or oil to produce an inflammable gas, one to operate while the other was cleansed and recharged. The resultant gas, together with the right amount of air, passed to a beam-operated pump and a water-cooled combustion chamber, and then to a water-cooled nozzle to an impulse gas turbine, which drove the pumps and provided the output. A clear description of the thermodynamic sequence known as the Joule Cycle (Brayton in the USA) is thus given. Further, the method of gas production predates Murdoch's lighting of the Soho foundry by gas.It seems unlikely that John Barber was able to get his engine to work; indeed, it was well over a hundred years before a continuous combustion chamber was achieved. However, the details of the specification, for example the use of cooling water jackets and injection, suggest that considerable experimentation had taken place.To be active in the taking out of patents over a period of 26 years is remarkable; that the best came after bankruptcy is more so. There is nothing to suggest that the cost of his experiments was the cause of his financial troubles.[br]Further ReadingA.K.Bruce, 1944, "John Barber and the gas turbine", Engineer 29 December: 506–8; 8 March (1946):216, 217.C.Lyle Cummins, 1976, Internal Fire, Carnot Press.JB -
8 Ebener, Erasmus
SUBJECT AREA: Metallurgy[br]b. 21 December 1511 Nuremberg, Germanyd. 24 November 1577 Helmstedt, Germany[br]German mining entrepreneur who introduced a new method ofbrassmaking.[br]A descendant of Nuremberg nobility, Ebener became recognized as a statesman in his native city and was employed also by foreign dignitaries. His appointment as Privy Councillor to the Dukes of Brunswick involved him in mining and metallurgical affairs at the great Rammelsberg mixed-ore mine at Goslar in the Harz mountains. About 1550, at Rammelsberg, Ebener is believed to have made brass by incorporating accretions of zinc formed in crevices of local lead-smelting furnaces. This small-scale production of impure zinc, formerly discarded as waste, could be used to replace calamine, the carbonate ore of zinc, which by tradition had been combined with copper in European brassmaking. Ercker, writing in 1574, mentions the accretions at Goslar obtained by removing furnace sections to make this material available for brass. The true nature of the zinc ore, calamine, and zinc metal compared with these accretions was determined only much later, but variation in quality with respect to impurities made the material most suitable for cast brassware rather than beaten goods. As quantities were small and much valued, distribution from Goslar was limited, not normally reaching Britain, where production of brasses continued to rely on calamine or expensive zinc imports from the East. Rammelsberg profited from the waste material accumulating over the years and its use at Bundheim brassworks east of Goslar. Ebener partnered Duke Henry the Younger of Brunswick in financing a new drainage adit at Rammelsberg, and was later granted several iron mines and smelting works. From 1556 he was granted rights to market calamine from the Lower Harz and copper sulphate from Rammelsberg. Ebener later had an important role at the court of Duke Julius, son of Henry, advising him on the founding of Helmstedt University.[br]Bibliography1572, "Sundry expositions on mines, metals and other useful things found in the Harz and especially at the Rammelsberg", reproduced and annotated by F.J.F.Meyer and J.F.L.Hausmann, 1805 Hercynian Archive.Further ReadingBeckmann, 1846, History of Inventions, Vol. II, trans.

10 Dony, Jean-Jacques Daniel
SUBJECT AREA: Metallurgy[br]b. 24 February 1759 Liège, Belgiumd. 6 November 1819 Liège, Belgium[br]Belgian inventor of the horizontal retort process of zinc manufacture.[br]Dony trained initially for the Church, and it is not known how he became interested in the production of zinc. Liège, however, was close to extensive deposits of the zinc ore calamine, and brass had been made since Roman times in the region between Liège and Aix-la-Chapelle (now Aachen). William Champion's technique of brass manufacture was known there and was considered to be too complicated and expensive for the routine manufacture of brass. Dony may have learned about earlier processes of manufacturing zinc on the European continent from his friend Professor Villette of Liège University, and about English methods from Henri Delloye, a friend of both Villette and Dony and who visited Birmingham and Bristol on their behalf to study zinc smelting processes and brass manufacture at first hand. By 21 March 1805 Dony had succeeded in extracting zinc from calamine and casting it in ingots. On the basis of this success he applied to the French Republican administration for assistance and in 1806 was assigned by Napoleon the sole mining rights to the calamine deposits of the Vieille Montagne, or Altenberg, near Moresnet, five miles (8 km) from Aachen. With these rights went the obligation of developing an industrially viable method of zinc refining. In 1807 he constructed a small factory at Isle and there, after much effort, he perfected his celebrated horizontal retort process, the "Liège Method". After July 1809 zinc was being produced in abundance, and in January 1810 Dony was granted an Imperial Patent giving him a monopoly of zinc manufacture for fifteen years. He erected a rolling mill at Saint-Léonard and attempted to persuade the Minister of Marine to use zinc sheets rather than copper for the protection of ships. Between 1809 and 1810 Dony reduced the price of zinc in Liège from 8.60 to 2.60 francs per kilo. However, after 1813 he began to encounter financial problems and in 1818 he surrendered his commercial interests to his partner Dominique Mosselman (d. 1837). The horizontal retort process soon rendered obsolete that of William Champion, and variants of the Liège Method were rapidly evolved in Germany, Britain and the USA.[br]Further ReadingA.Dony, 1941, A Propos de l'industrie belge du zinc au début du XIXe siècle, Brussels.

14 Roebuck, John
SUBJECT AREA: Chemical technology[br]b. 1718 Sheffield, Englandd. 17 July 1794[br]English chemist and manufacturer, inventor of the lead-chamber process for sulphuric acid.[br]The son of a prosperous Sheffield manufacturer, Roebuck forsook the family business to pursue studies in medicine at Edinburgh University. There he met Dr Joseph Black (1727–99), celebrated Professor of Chemistry, who aroused in Roebuck a lasting interest in chemistry. Roebuck continued his studies at Leyden, where he took his medical degree in 1742. He set up in practice in Birmingham, but in his spare time he continued chemical experiments that might help local industries.Among his early achievements was his new method of refining gold and silver. Success led to the setting up of a large laboratory and a reputation as a chemical consultant. It was at this time that Roebuck devised an improved way of making sulphuric acid. This vital substance was then made by burning sulphur and nitre (potassium nitrate) over water in a glass globe. The scale of the process was limited by the fragility of the glass. Roebuck substituted "lead chambers", or vessels consisting of sheets of lead, a metal both cheap and resistant to acids, set in wooden frames. After the first plant was set up in 1746, productivity rose and the price of sulphuric acid fell sharply. Success encouraged Roebuck to establish a second, larger plant at Prestonpans, near Edinburgh. He preferred to rely on secrecy rather than patents to preserve his monopoly, but a departing employee took the secret with him and the process spread rapidly in England and on the European continent. It remained the standard process until it was superseded by the contact process towards the end of the nineteenth century. Roebuck next turned his attention to ironmaking and finally selected a site on the Carron river, near Falkirk in Scotland, where the raw materials and water power and transport lay close at hand. The Carron ironworks began producing iron in 1760 and became one of the great names in the history of ironmaking. Roebuck was an early proponent of the smelting of iron with coke, pioneered by Abraham Darby at Coalbrookdale. To supply the stronger blast required, Roebuck consulted John Smeaton, who c. 1760 installed the first blowing cylinders of any size.All had so far gone well for Roebuck, but he now leased coal-mines and salt-works from the Duke of Hamilton's lands at Borrowstonness in Linlithgow. The coal workings were plagued with flooding which the existing Newcomen engines were unable to overcome. Through his friendship with Joseph Black, patron of James Watt, Roebuck persuaded Watt to join him to apply his improved steam-engine to the flooded mine. He took over Black's loan to Watt of £1,200, helped him to obtain the first steam-engine patent of 1769 and took a two-thirds interest in the project. However, the new engine was not yet equal to the task and the debts mounted. To satisfy his creditors, Roebuck had to dispose of his capital in his various ventures. One creditor was Matthew Boulton, who accepted Roebuck's two-thirds share in Watt's steam-engine, rather than claim payment from his depleted estate, thus initiating a famous partnership. Roebuck was retained to manage Borrowstonness and allowed an annuity for his continued support until his death in 1794.[br]Further ReadingMemoir of John Roebuck in J.Roy. Soc.
