43 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 -
44 Giffard, Baptiste Henry Jacques (Henri)
[br]b. 8 February 1825 Paris, Franced. 14 April 1882 Paris, France[br]French pioneer of airships and balloons, inventor of an injector for steam-boiler feedwater.[br]Giffard entered the works of the Western Railway of France at the age of 16 but became absorbed by the problem of steam-powered aerial navigation. He proposed a steam-powered helicopter in 1847, but he then turned his attention to an airship. He designed a lightweight coke-burning, single-cylinder steam engine and boiler which produced just over 3 hp (2.2 kW) and mounted it below a cigar-shaped gas bag 44 m (144 ft) in length. A triangular rudder was fitted at the rear to control the direction of flight. On 24 September 1852 Giffard took off from Paris and, at a steady 8 km/h (5 mph), he travelled 28 km (17 miles) to Trappes. This can be claimed to be the first steerable lighter-than-air craft, but with a top speed of only 8 km/h (5 mph) even a modest headwind would have reduced the forward speed to nil (or even negative). Giffard built a second airship, which crashed in 1855, slightly injuring Giffard and his companion; a third airship was planned with a very large gas bag in order to lift the inherently heavy steam engine and boiler, but this was never built. His airships were inflated by coal gas and refusal by the gas company to provide further supplies brought these promising experiments to a premature end.As a draughtsman Giffard had the opportunity to travel on locomotives and he observed the inadequacies of the feed pumps then used to supply boiler feedwater. To overcome these problems he invented the injector with its series of three cones: in the first cone (convergent), steam at or below boiler pressure becomes a high-velocity jet; in the second (also convergent), it combines with feedwater to condense and impart high velocity to it; and in the third (divergent), that velocity is converted into pressure sufficient to overcome the pressure of steam in the boiler. The injector, patented by Giffard, was quickly adopted by railways everywhere, and the royalties provided him with funds to finance further experiments in aviation. These took the form of tethered hydrogen-inflated balloons of successively larger size. At the Paris Exposition of 1878 one of these balloons carried fifty-two passengers on each tethered "flight". The height of the balloon was controlled by a cable attached to a huge steam-powered winch, and by the end of the fair 1,033 ascents had been made and 35,000 passengers had seen Paris from the air. This, and similar balloons, greatly widened the public's interest in aeronautics. Sadly, after becoming blind, Giffard committed suicide; however, he died a rich man and bequeathed large sums of money to the State for humanitarian an scientific purposes.[br]Principal Honours and DistinctionsCroix de la Légion d'honneur 1863.Bibliography1860, Notice théorique et pratique sur l'injecteur automoteur.1870, Description du premier aérostat à vapeur.Further ReadingDictionnaire de biographie française.Gaston Tissandier, 1872, Les Ballons dirigeables, Paris.—1878, Le Grand ballon captif à vapeur de M.
