14 Hall, Joseph
SUBJECT AREA: Metallurgy[br]b. 1789d. 1862[br]English ironmaker who invented the wet puddling process.[br]Hall was a practical man with no theoretical background: his active years were spent at Bloomfield Ironworks, Tipton, Staffordshire. Around 1816 he began experimenting in the production of wrought iron. At that time, blast-furnace or cast iron was converted to wrought iron by the dry puddling process invented by Henry Cort in 1784. In this process, the iron was decarburized (i.e. had its carbon removed) by heating it in a current of air in a furnace with a sand bed. Some of the iron combined with the silica in the sand to form a slag, however, so that no less than 2 tons of cast iron were needed to produce 1 ton of wrought. Hall found that if bosh cinder was charged into the furnace, a vigorous reaction occurred in which the cast iron was converted much more quickly than before, to produce better quality wrought iron, a ton of which could be formed by no more than 21 cwt (1,067 kg) of cast iron. Because of the boiling action, the process came to be known as pig boiling. Bosh cinder, essentially iron oxide, was formed in the water troughs or boshes in which workers cooled their tools used in puddling and reacted with the carbon in the cast iron. The advantages of pig boiling over dry puddling were striking enough for the process to be widely used by the late 1820s. By mid-century it was virtually the only process used for producing wrought iron, an essential material for mechanical and civil engineering during the Industrial Revolution. Hall reckoned that if he had patented his invention he would have "made a million". As luck would have it, the process that he did patent in 1838 left his finances unchanged: this was for the roasting of cinder for use as the base of the puddling furnace, providing better protection than the bosh cinder for the iron plates that formed the base.[br]Bibliography1857, The Iron Question Considered in Connection with Theory, Practice and Experience with Special Reference to the Bessemer Process, London.Further ReadingJ.Percy, 1864, Metallurgy.

15 Darby, Abraham
SUBJECT AREA: Metallurgy[br]b. 1678 near Dudley, Worcestershire, Englandd. 5 May 1717 Madely Court, Coalbrookdale, Shropshire, England[br]English ironmaster, inventor of the coke smelting of iron ore.[br]Darby's father, John, was a farmer who also worked a small forge to produce nails and other ironware needed on the farm. He was brought up in the Society of Friends, or Quakers, and this community remained important throughout his personal and working life. Darby was apprenticed to Jonathan Freeth, a malt-mill maker in Birmingham, and on completion of his apprenticeship in 1699 he took up the trade himself in Bristol. Probably in 1704, he visited Holland to study the casting of brass pots and returned to Bristol with some Dutch workers, setting up a brassworks at Baptist Mills in partnership with others. He tried substituting cast iron for brass in his castings, without success at first, but in 1707 he was granted a patent, "A new way of casting iron pots and other pot-bellied ware in sand without loam or clay". However, his business associates were unwilling to risk further funds in the experiments, so he withdrew his share of the capital and moved to Coalbrookdale in Shropshire. There, iron ore, coal, water-power and transport lay close at hand. He took a lease on an old furnace and began experimenting. The shortage and expense of charcoal, and his knowledge of the use of coke in malting, may well have led him to try using coke to smelt iron ore. The furnace was brought into blast in 1709 and records show that in the same year it was regularly producing iron, using coke instead of charcoal. The process seems to have been operating successfully by 1711 in the production of cast-iron pots and kettles, with some pig-iron destined for Bristol. Darby prospered at Coalbrookdale, employing coke smelting with consistent success, and he sought to extend his activities in the neighbourhood and in other parts of the country. However, ill health prevented him from pursuing these ventures with his previous energy. Coke smelting spread slowly in England and the continent of Europe, but without Darby's technological breakthrough the ever-increasing demand for iron for structures and machines during the Industrial Revolution simply could not have been met; it was thus an essential component of the technological progress that was to come.Darby's eldest son, Abraham II (1711–63), entered the Coalbrookdale Company partnership in 1734 and largely assumed control of the technical side of managing the furnaces and foundry. He made a number of improvements, notably the installation of a steam engine in 1742 to pump water to an upper level in order to achieve a steady source of water-power to operate the bellows supplying the blast furnaces. When he built the Ketley and Horsehay furnaces in 1755 and 1756, these too were provided with steam engines. Abraham II's son, Abraham III (1750–89), in turn, took over the management of the Coalbrookdale works in 1768 and devoted himself to improving and extending the business. His most notable achievement was the design and construction of the famous Iron Bridge over the river Severn, the world's first iron bridge. The bridge members were cast at Coalbrookdale and the structure was erected during 1779, with a span of 100 ft (30 m) and height above the river of 40 ft (12 m). The bridge still stands, and remains a tribute to the skill and judgement of Darby and his workers.[br]Further ReadingA.Raistrick, 1989, Dynasty of Iron Founders, 2nd edn, Ironbridge Gorge Museum Trust (the best source for the lives of the Darbys and the work of the company).H.R.Schubert, 1957, History of the British Iron and Steel Industry AD 430 to AD 1775, London: Routledge \& Kegan Paul.LRD -
16 Talbot, Benjamin
SUBJECT AREA: Metallurgy[br]b. 19 September 1864 Wellington, Shropshire, Englandd. 16 December 1947 Solberge Hall, Northallerton, Yorkshire, England[br]Talbot, William Henry Fox English steelmaker and businessman who introduced a technique for producing steel "continuously" in large tilting basic-lined open-hearth furnaces.[br]After spending some years at his father's Castle Ironworks and at Ebbw Vale Works, Talbot travelled to the USA in 1890 to become Superintendent of the Southern Iron and Steel Company of Chattanooga, Tennessee, where he initiated basic open-hearth steelmaking and a preliminary slag washing to remove silicon. In 1893 he moved to Pennsylvania as Steel Superintendent at the Pencoyd works; there, six years later, he began his "continuous" steelmaking process. Returning to Britain in 1900, Talbot marketed the technique: after ten years it was in successful use in Britain, continental Europe and the USA; it promoted the growth of steel production.Meanwhile its originator had joined the Cargo Fleet Iron Company Limited on Teesside, where he was made Managing Director in 1907. Twelve years later he assumed, in addition, the same position in the allied South Durham Steel and Iron Company Limited. While remaining Managing Director, he was appointed Deputy Chairman of both companies in 1925, and Chairman in 1940. The companies he controlled survived the depressed 1920s and 1930s and were significant contributors to British steel output, with a capacity of more than half a million tonnes per year.[br]Principal Honours and DistinctionsPresident, Iron and Steel Institute 1928, and (British) National Federation of Iron and Steel Manufacturers.

17 Albert, Wilhelm August Julius
SUBJECT AREA: Mining and extraction technology[br]b. 24 January 1787 Hannover, Germanyd. 4 July 1846 Clausthal, Harz, Germany[br]German mining official, successful applier of wire cable.[br]After studying law at the University of Göttingen, Albert turned to the mining industry and in 1806 started his career in mining administration in the Harz district, where he became Chief Inspector of mines thirty years later. His influence on the organization of the mining industry was considerable and he contributed valuable ideas for the development of mining technology. For example, he initiated experiments with Reichenbach's water-column pump in Harz when it had been working successfully in the transportation of brine in Bavaria, and he encouraged Dörell to work on his miner's elevator.The increasing depths of shafts in the Harz district brought problems with hoisting as the ropes became too heavy and tended to break. At the beginning of the nineteenth century, iron link chains replaced the hempen ropes which were expensive and wore out too quickly, especially in the wet conditions in the shafts. After he had experimented for six years using counterbalancing iron link chains, which broke too easily, in 1834 he conceived the idea of producing stranded cables from iron wires. Their breaking strength and flexibility depended greatly on the softness of the iron and the way of laying the strands. Albert produced the cable by attaching the wires to strings which he turned evenly; this method became known as "Albert lay". He was not the first to conceive the idea of metal cables: there exists evidence for such cables as far back as Pompeii; Leonardo da Vinci made sketches of cables made from brass wires; and in 1780 the French engineer Reignier applied iron cables for lightning conductors. The idea also developed in various other mining areas, but Albert cables were the first to gain rapidly direct common usage worldwide.[br]Bibliography1835, "Die Anfertigung von Treibseilen aus geflochtenem Eisendraht", Karstens Archiv 8: 418–28.Further ReadingK.Karmarsch, "W.A.J.Albert", Allgemeine deutsche Biographie 1:212–3.W.Bornhardt, 1934, W.A.J.Albert und die Erfindung der Eisendrahtseile, Berlin (a detailed description of his inventions, based on source material).C.Bartels, 1992, Vom frühneuzeitlichen Montangewerbe zur Bergbauindustrie, Bochum: Deut sches Bergbau-Museum (evaluates his achievements within the framework of technological development in the Harz mining industry).WKBiographical history of technology > Albert, Wilhelm August Julius

SUBJECT AREA: Metallurgy[br]b. 29 June 1701 Caen, Franced. 3 January 1778 Versailles, France[br]French medical practitioner who suggested producing tin plate with zinc.[br]Setting out to study law, Malouin turned to scientific studies, settling in Paris to teach and practice medicine. He retained his scientific interest in the field of chemistry, producing memoirs on zinc and tin, and. as early as 1742 suggested that a type of tin plate might instead be produced with zinc. A method of zinc-coating hammered-iron saucepans was introduced briefly at Rouen in the early 1780s.His contribution to early volumes of Diderot's Encyclopédie included those on "Alchemy", "Antimony", "Acid" and "Alkali". Malouin also applied his scientific knowledge to articles on milling and baking for the Academy in Descriptions des arts et métiers.[br]Principal Honours and DistinctionsElected to Academy 1742.

19 Bedson, George
SUBJECT AREA: Metallurgy[br]b. 3 November 1820 Sutton Coldfield, Warwickshire, Englandd. 12 December 1884 Manchester (?), England[br]English metallurgist, inventor of the continuous rolling mill.[br]He acquired a considerable knowledge of wire-making in his father's works before he took a position in 1839 at the works of James Edleston at Warrington. From there, in 1851, he went to Manchester as Manager of Richard Johnson \& Sons' wire mill, where he remained for the rest of his life. It was there that he initiated several important improvements in the manufacture of wire. These included a system of circulating puddling furnace water bottoms and sides, and a galvanizing process. His most important innovation, however, was the continuous mill for producing iron rod for wiredrawing. Previously the red-hot iron billets had to be handled repeatedly through a stand or set of rolls to reduce the billet to the required shape, with time and heat being lost at each handling. In Bedson's continuous mill, the billet entered the first of a succession of stands placed as closely to each other as possible and emerged from the final one as rod suitable for wiredrawing, without any intermediate handling. A second novel feature was that alternate rolls were arranged vertically to save turning the piece manually through a right angle. That improved the quality as well as the speed of production. Bedson's first continuous mill was erected in Manchester in 1862 and had sixteen stands in tandem. A mill on this principle had been patented the previous year by Charles While of Pontypridd, South Wales, but it was Bedson who made it work and brought it into use commercially. A difficult problem to overcome was that as the piece being rolled lengthened, its speed increased, so that each pair of rolls had to increase correspondingly. The only source of power was a steam engine working a single drive shaft, but Bedson achieved the greater speeds by using successively larger gear-wheels at each stand.Bedson's first mill was highly successful, and a second one was erected at the Manchester works; however, its application was limited to the production of small bars, rods and sections. Nevertheless, Bedson's mill established an important principle of rolling-mill design that was to have wider applications in later years.[br]Further ReadingObituary, 1884, Journal of the Iron and Steel Institute 27:539–40.

20 Turner, Richard
[br]b. 1798 probably Dublin, Ireland d. 1881[br]Irish engineer offerrovitreous structures such as glasshouses and roofs of railway terminus buildings. Lime Street Station, Liverpool, erected 1849–50, was a notable example of the latter.[br]Turner's first glasshouse commission was for the Palm House at the Botanic Gardens in Belfast, begun in 1839; this structure was designed by Charles Lanyon, Turner being responsible for the ironwork construction. The Belfast Palm House was followed in 1843 by the Palm House for the Royal Dublin Society, but the structure for which Turner is best known is the famous Palm House in the Royal Botanic Gardens at Kew Gardens in London. This was originally designed in 1844 by the architect Decimus Burton, but his concept was rejected and Turner was asked to design a new one. Burton tried again, basing his new design upon that of Turner but also incorporating features that made it more similar to the famous Great Conservatory by Paxton at Chatsworth. Finally, Turner was contracted to build the Palm Stove in collaboration with Burton. Completed in 1848, the Kew Palm House is the finest example of the glasshouses of that era. This remarkable structure is simple but impressive: it is 362 ft (110 m) long and is covered by 45,000 ft2 (4,180 m2) of greenish glass. Inside, in the central taller part, a decorative, cast-iron, spiral staircase gives access to an upper gallery, from where tall plants may be clearly viewed; the roof rises to 62 ft (19 m). The curving, glazed panels, set in ribs of wrought iron, rise from a low masonry wall. The ingenious method of construction of these ribs was patented by Turner in 1846. It consists of wrought-iron tie rods inserted into hollow cast-iron tubes; these can be tightened after the erection of the building is complete, so producing a stable, balanced structure not unlike the concept of a timber-trussed roof. The Palm Stove has only recently undergone extensive adaptation to modern needs.[br]Further ReadingJ.Hix, 1974, The Glass House, Cambridge, Mass.: MIT Press, pp. 122–7 (the Palm House at Kew).U.Kulturmann, 1979, Architecture and Urbanism, Tokyo, pp. 76–81 (the Palm House at Kew).DY
