8 Parry, George
SUBJECT AREA: Metallurgy[br]fl. 1800–1850 Wales[br]Welsh ironmaker and inventor of the bell and hopper for blastfurnaces.[br]Until the mid-nineteenth century, blast furnaces were open at the top to facilitate loading of the iron ore, fuel and flux (the charge). However, that arrangement allowed the hot gases produced in the furnace to escape, whereas they could have been used to heat boilers or the incoming air blast. Attempts had been made to capture the fugitive gases, but they had all failed until George Parry devised his bell and hopper equipment for dosing the throat or top of the furnace. He fixed an inverted cone or hopper inside the throat and arranged inside it a cast-iron bell that could be raised or lowered. When in the raised position, it was in contact with the underside of the hopper, thus sealing the furnace. The hot gases could then be led off through a large pipe to do useful work. The charge was dropped onto the bell, and when enough had accumulated there the bell was lowered, allowing the charge to fall into the furnace. The gas escaped only for the brief period that the bell was lowered. The advantages of this arrangement were soon realized by other ironmasters and it was quite rapidly, and then generally, adopted. The device was still in use in the 1990s, with modifications.[br]Bibliography1858, "On the principal causes of derangements in blast furnaces", Proceedings of the South Wales Institute of Engineers 1:26–39 (describes his improvements to the blast furnace), 28 ff.

9 Siemens, Sir Charles William
[br]b. 4 April 1823 Lenthe, Germanyd. 19 November 1883 London, England[br]German/British metallurgist and inventory pioneer of the regenerative principle and open-hearth steelmaking.[br]Born Carl Wilhelm, he attended craft schools in Lübeck and Magdeburg, followed by an intensive course in natural science at Göttingen as a pupil of Weber. At the age of 19 Siemens travelled to England and sold an electroplating process developed by his brother Werner Siemens to Richard Elkington, who was already established in the plating business. From 1843 to 1844 he obtained practical experience in the Magdeburg works of Count Stolburg. He settled in England in 1844 and later assumed British nationality, but maintained close contact with his brother Werner, who in 1847 had co-founded the firm Siemens \& Halske in Berlin to manufacture telegraphic equipment. William began to develop his regenerative principle of waste-heat recovery and in 1856 his brother Frederick (1826–1904) took out a British patent for heat regeneration, by which hot waste gases were passed through a honeycomb of fire-bricks. When they became hot, the gases were switched to a second mass of fire-bricks and incoming air and fuel gas were led through the hot bricks. By alternating the two gas flows, high temperatures could be reached and considerable fuel economies achieved. By 1861 the two brothers had incorporated producer gas fuel, made by gasifying low-grade coal.Heat regeneration was first applied in ironmaking by Cowper in 1857 for heating the air blast in blast furnaces. The first regenerative furnace was set up in Birmingham in 1860 for glassmaking. The first such furnace for making steel was developed in France by Pierre Martin and his father, Emile, in 1863. Siemens found British steelmakers reluctant to adopt the principle so in 1866 he rented a small works in Birmingham to develop his open-hearth steelmaking furnace, which he patented the following year. The process gradually made headway; as well as achieving high temperatures and saving fuel, it was slower than Bessemer's process, permitting greater control over the content of the steel. By 1900 the tonnage of open-hearth steel exceeded that produced by the Bessemer process.In 1872 Siemens played a major part in founding the Society of Telegraph Engineers (from which the Institution of Electrical Engineers evolved), serving as its first President. He became President for the second time in 1878. He built a cable works at Charlton, London, where the cable could be loaded directly into the holds of ships moored on the Thames. In 1873, together with William Froude, a British shipbuilder, he designed the Faraday, the first specialized vessel for Atlantic cable laying. The successful laying of a cable from Europe to the United States was completed in 1875, and a further five transatlantic cables were laid by the Faraday over the following decade.The Siemens factory in Charlton also supplied equipment for some of the earliest electric-lighting installations in London, including the British Museum in 1879 and the Savoy Theatre in 1882, the first theatre in Britain to be fully illuminated by electricity. The pioneer electric-tramway system of 1883 at Portrush, Northern Ireland, was an opportunity for the Siemens company to demonstrate its equipment.[br]Principal Honours and DistinctionsKnighted 1883.

12 Cowper, Edward Alfred
SUBJECT AREA: Metallurgy[br]b. 10 December 1819 London, Englandd. 9 May 1893 Weybridge, Surrey, England[br]English inventor of the hot-blast stove used in ironmaking.[br]Cowper was apprenticed in 1834 to John Braithwaite of London and in 1846 obtained employment at the engineers Fox \& Henderson in Birmingham. In 1851 he was engaged in the contract drawings for the Crystal Palace housing the Great Exhibition, and in the same year he set up in London as a consulting engineer. Cowper designed the 211 ft (64.3 m) span roof of Birmingham railway station, the first large-span station roof to be constructed. Cowper had an inventive turn of mind. While still an apprentice, he devised the well-known railway fog-signal and, at Fox \& Henderson, he invented an improved method of casting railway chairs. Other inventions included a compound steam-engine with receiver, patented in 1857; a bicycle wheel with steel spokes and rubber tyre (1868); and an electric writing telegraph (1879). Cowper's most important invention by far was the hot-blast stove, the first application of C.W. Siemens's regenerative principle to ironmaking, patented in 1857. Waste gases from the blast furnace were burnt in an iron chamber lined with a honeycomb of firebricks. When they were hot, the gas was directed to a second similar chamber while the incoming air blast for the blast furnace was heated by passing it through the first chamber. The stoves alternatively received and gave up heat and the heated blast, introduced by J.B. Neilson, led to considerable fuel economies in blast-furnace operation; the system is still in use. Cowper played an active part in the engineering institutions of his time, becoming President of the Institution of Mechanical Engineers in 1880–1. He was commissioned by the Science and Art Department to catalogue the collections of machinery and inventions at the South Kensington Museum, whose science collections now form the Science Museum, London.[br]Principal Honours and DistinctionsPresident, Institution of Mechanical Engineers 1880–1.Further ReadingObituary, 1893, Journal of the Iron and Steel Institute: 172–3, London.W.K.V.Gale, 1969, Iron and Steel, London: Longmans, pp. 42, 75 (describes his hot-blast stoves).LRD -
13 Seguin, Marc
[br]b. 20 April 1786 Annonay, Ardèche, Franced. 24 February 1875 Annonay, Ardèche, France[br]French engineer, inventor of multi-tubular firetube boiler.[br]Seguin trained under Joseph Montgolfier, one of the inventors of the hot-air balloon, and became a pioneer of suspension bridges. In 1825 he was involved in an attempt to introduce steam navigation to the River Rhône using a tug fitted with a winding drum to wind itself upstream along a cable attached to a point on the bank, with a separate boat to transfer the cable from point to point. The attempt proved unsuccessful and was short-lived, but in 1825 Seguin had decided also to seek a government concession for a railway from Saint-Etienne to Lyons as a feeder of traffic to the river. He inspected the Stockton \& Darlington Railway and met George Stephenson; the concession was granted in 1826 to Seguin Frères \& Ed. Biot and two steam locomotives were built to their order by Robert Stephenson \& Co. The locomotives were shipped to France in the spring of 1828 for evaluation prior to construction of others there; each had two vertical cylinders, one each side between front and rear wheels, and a boiler with a single large-diameter furnace tube, with a watertube grate. Meanwhile, in 1827 Seguin, who was still attempting to produce a steamboat powerful enough to navigate the fast-flowing Rhône, had conceived the idea of increasing the heating surface of a boiler by causing the hot gases from combustion to pass through a series of tubes immersed in the water. He was soon considering application of this type of boiler to a locomotive. He applied for a patent for a multi-tubular boiler on 12 December 1827 and carried out numerous experiments with various means of producing a forced draught to overcome the perceived obstruction caused by the small tubes. By May 1829 the steam-navigation venture had collapsed, but Seguin had a locomotive under construction in the workshops of the Lyons-Sain t- Etienne Railway: he retained the cylinder layout of its Stephenson locomotives, but incorporated a boiler of his own design. The fire was beneath the barrel, surrounded by a water-jacket: a single large flue ran towards the front of the boiler, whence hot gases returned via many small tubes through the boiler barrel to a chimney above the firedoor. Draught was provided by axle-driven fans on the tender.Seguin was not aware of the contemporary construction of Rocket, with a multi-tubular boiler, by Robert Stephenson; Rocket had its first trial run on 5 September 1829, but the precise date on which Seguin's locomotive first ran appears to be unknown, although by 20 October many experiments had been carried out upon it. Seguin's concept of a multi-tubular locomotive boiler therefore considerably antedated that of Henry Booth, and his first locomotive was completed about the same date as Rocket. It was from Rocket's boiler, however, rather than from that of Seguin's locomotive, that the conventional locomotive boiler was descended.[br]BibliographyFebruary 1828, French patent no. 3,744 (multi-tubular boiler).1839, De l'Influence des chemins de fer et de l'art de les tracer et de les construire, Paris.Further ReadingF.Achard and L.Seguin, 1928, "Marc Seguin and the invention of the tubular boiler", Transactions of the Newcomen Society 7 (traces the chronology of Seguin's boilers).——1928, "British railways of 1825 as seen by Marc Seguin", Transactions of the Newcomen Society 7.J.B.Snell, 1964, Early Railways, London: Weidenfeld \& Nicolson.J.-M.Combe and B.Escudié, 1991, Vapeurs sur le Rhône, Lyons: Presses Universitaires de Lyon.PJGR -
