23 Donkin, Bryan III
SUBJECT AREA: Mechanical, pneumatic and hydraulic engineering, Steam and internal combustion engines[br]b. 29 August 1835 London, Englandd. 4 March 1902 Brussels, Belgium[br]English mechanical engineer.[br]Bryan Donkin was the eldest son of John Donkin (1802–54) and grandson of Bryan Donkin I (1768–1855). He was educated at University College, London, and at the Ecole Centrale des Arts et Métiers in Paris, and then served an apprenticeship in the firm established by his grandfather. He assisted his uncle, Bryan Donkin II (1809–93), in setting up paper mills at St Petersburg. He became a partner in the Donkin firm in 1868 and Chairman in 1889, and retained this position after the amalgamation with Clench \& Co. of Chesterfield in 1900. Bryan Donkin was one of the first engineers to carry out scientific tests on steam engines and boilers, the results of his experiments being reported in many papers to the engineering institutions. In the 1890s his interests extended to the internal-combustion engine and he translated Rudolf Diesel's book Theory and Construction of a Rational Heat Motor. He was a frequent contributor to the weekly journal The Engineer. He was a member of the Institution of Civil Engineers and of the Institution of Mechanical Engineers, as well as of many other societies, including the Royal Institution, the American Society of Mechanical Engineers, the Société Industrielle de Mulhouse and the Verein Deutscher Ingenieure. In his experimental work he often collaborated with others, notably Professor A.B.W.Kennedy (1847–1928), with whom he was also associated in the consulting engineering firm of Kennedy \& Donkin.[br]Principal Honours and DistinctionsVice-President, Institution of Mechanical Engineers 1901.

24 Stumpf, Johann
SUBJECT AREA: Steam and internal combustion engines[br]fl. c. 1900 Germany[br]German inventor of a successful design of uniflow steam engine.[br]In 1869 Stumpf was commissioned by the Pope Manufacturing Company of Hertford, Connecticut, to set up two triple-expansion, vertical, Corliss pumping engines. He tried to simplify this complicated system and started research with the internal combustion engine and the steam turbine particularly as his models. The construction of steam turbines in several stages where the steam passed through in a unidirectional flow was being pursued at that time, and Stumpf wondered whether it would be possible to raise the efficiency of a reciprocating steam engine to the same thermal level as the turbine by the use of the uniflow principle.Stumpf began to investigate these principles without studying the work of earlier pioneers like L.J. Todd, which he later thought would have led him astray. It was not until 1908, when he was Professor at the Institute of Technology in Berlin- Charlottenburg, that he patented his successful "una-flow" steam engine. In that year he took out six British patents for improvements in details on his original one Stumpf fully realized the thermal advantages of compressing the residual steam and was able to evolve systems of coping with excessive compression when starting. He also placed steam-jackets around the ends of the cylinder. Stumpf's first engine was built in 1908 by the Erste B runner Maschinenfabrik-Gesellschaft, and licences were taken out by many other manufacturers, including those in Britain and the USA. His engine was developed into the most economical type of reciprocating steam engine.[br]Bibliography1912, The Una-Flow Steam Engine, Munich: R.

33 Carnot, Nicolas Léonard Sadi
SUBJECT AREA: Steam and internal combustion engines[br]b. 1 June 1796 Paris, Franced. 24 August 1831 Paris, France[br]French laid the foundations for modern thermodynamics through his book Réflexions sur la puissance motrice du feu when he stated that the efficiency of an engine depended on the working substance and the temperature drop between the incoming and outgoing steam.[br]Sadi was the eldest son of Lazare Carnot, who was prominent as one of Napoleon's military and civil advisers. Sadi was born in the Palais du Petit Luxembourg and grew up during the Napoleonic wars. He was tutored by his father until in 1812, at the minimum age of 16, he entered the Ecole Polytechnique to study stress analysis, mechanics, descriptive geometry and chemistry. He organized the students to fight against the allies at Vincennes in 1814. He left the Polytechnique that October and went to the Ecole du Génie at Metz as a student second lieutenant. While there, he wrote several scientific papers, but on the Restoration in 1815 he was regarded with suspicion because of the support his father had given Napoleon. In 1816, on completion of his studies, Sadi became a second lieutenant in the Metz engineering regiment and spent his time in garrison duty, drawing up plans of fortifications. He seized the chance to escape from this dull routine in 1819 through an appointment to the army general staff corps in Paris, where he took leave of absence on half pay and began further courses of study at the Sorbonne, Collège de France, Ecole des Mines and the Conservatoire des Arts et Métiers. He was inter-ested in industrial development, political economy, tax reform and the fine arts.It was not until 1821 that he began to concentrate on the steam-engine, and he soon proposed his early form of the Carnot cycle. He sought to find a general solution to cover all types of steam-engine, and reduced their operation to three basic stages: an isothermal expansion as the steam entered the cylinder; an adiabatic expansion; and an isothermal compression in the condenser. In 1824 he published his Réflexions sur la puissance motrice du feu, which was well received at the time but quickly forgotten. In it he accepted the caloric theory of heat but pointed out the impossibility of perpetual motion. His main contribution to a correct understanding of a heat engine, however, lay in his suggestion that power can be produced only where there exists a temperature difference due "not to an actual consumption of caloric but to its transportation from a warm body to a cold body". He used the analogy of a water-wheel with the water falling around its circumference. He proposed the true Carnot cycle with the addition of a final adiabatic compression in which motive power was con sumed to heat the gas to its original incoming temperature and so closed the cycle. He realized the importance of beginning with the temperature of the fire and not the steam in the boiler. These ideas were not taken up in the study of thermodynartiics until after Sadi's death when B.P.E.Clapeyron discovered his book in 1834.In 1824 Sadi was recalled to military service as a staff captain, but he resigned in 1828 to devote his time to physics and economics. He continued his work on steam-engines and began to develop a kinetic theory of heat. In 1831 he was investigating the physical properties of gases and vapours, especially the relationship between temperature and pressure. In June 1832 he contracted scarlet fever, which was followed by "brain fever". He made a partial recovery, but that August he fell victim to a cholera epidemic to which he quickly succumbed.[br]Bibliography1824, Réflexions sur la puissance motrice du feu; pub. 1960, trans.

34 Diesel, Rudolph Christian Karl
SUBJECT AREA: Steam and internal combustion engines[br]b. 1858 Paris, Franced. 1913 at sea, in the English Channel[br]German inventor of the Diesel or Compression Ignition engine.[br]A German born in Paris, he was educated in Augsburg and later in Munich, where he graduated first in his class. There he took some courses under Professor Karl von Linde, pioneer of mechanical refrigeration and an authority on thermodynamics, who pointed out the low efficiency of the steam engine. He went to work for the Linde Ice Machine Company as an engineer and later as Manager; there he conceived a new basic cycle and worked out its thermodynamics, which he published in 1893 as "The theory and construction of a rational heat motor". Compressing air adiabatically to one-sixteenth of its volume caused the temperature to rise to 1,000°F (540°C). Injected fuel would then ignite automatically without any electrical system. He obtained permission to use the laboratories of the Augsburg-Nuremburg Engine Works to build a single-cylinder prototype. On test it blew up, nearly killing Diesel. He proved his principle, however, and obtained financial support from the firm of Alfred Krupp. The design was refined until successful and in 1898 an engine was put on display in Munich with the result that many business people invested in Diesel and his engine and its worldwide production. Diesel made over a million dollars out of the invention. The heart of the engine is the fuel-injection pump, which operates at a pressure of c.500 psi (35 kg/cm). The first English patent for the engine was in 1892. The firms in Augsburg sent him abroad to sell his engine; he persuaded the French to adopt it for submarines, Germany having refused this. Diesel died in 1913 in mysterious circumstances, vanishing from the Harwich-Antwerp ferry.[br]Further ReadingE.Diesel, 1937, Diesel, derMensch, das Werk, das Schicksal, Hamburg.

35 Kirk, Alexander Carnegie
[br]b. c.1830 Barry, Angus, Scotlandd. 5 October 1892 Glasgow, Scotland[br]Scottish marine engineer, advocate of multiple-expansion in steam reciprocating engines.[br]Kirk was a son of the manse, and after attending school at Arbroath he proceeded to Edinburgh University. Following graduation he served an apprenticeship at the Vulcan Foundry, Glasgow, before serving first as Chief Draughtsman with the Thames shipbuilders and engineers Maudslay Sons \& Field, and later as Engineer of Paraffin Young's Works at Bathgate and West Calder in Lothian. He was credited with the inventions of many ingenious appliances and techniques for improving production in these two establishments. About 1866 Kirk returned to Glasgow as Manager of the Cranstonhill Engine Works, then moved to Elder's Shipyard (later known as the Fairfield Company) as Engineering Manager. There he made history in producing the world's first triple-expansion engines for the single-screw steamship Propontis in 1874. That decade was to confirm the Clyde's leading role as shipbuilders to the world and to establish the iron ship with efficient reciprocating machinery as the workhorse of the British Merchant Marine. Upon the death of the great Clyde shipbuilder Robert Napier in 1876, Kirk and others took over as partners in the shipbuilding yard and engine shops of Robert Napier \& Sons. There in 1881 they built a ship that is acknowledged as one of the masterpieces of British shipbuilding: the SS Aberdeen for George Thompson's Aberdeen Line to the Far East. In this ship the fullest advantage was taken of high steam temperatures and pressures, which were expanded progressively in a three-cylinder configuration. The Aberdeen, in its many voyages from London to China and Japan, was to prove the efficiency of these engines that had been so carefully designed in Glasgow. In the following years Dr Kirk (he has always been known as Doctor, although his honorary LLD was only awarded by Glasgow University in 1888) persuaded the Admiralty and several shipping companies to accept not only triple-expansion machinery but also the use of mild steel in ship construction. The successful SS Parisian, built for the Allan Line of Glasgow, was one of these pioneer ships.[br]Principal Honours and DistinctionsFellow of the Royal Society of Edinburgh.FMWBiographical history of technology > Kirk, Alexander Carnegie

36 Smeaton, John
SUBJECT AREA: Civil engineering, Mechanical, pneumatic and hydraulic engineering, Steam and internal combustion engines[br]b. 8 June 1724 Austhorpe, near Leeds, Yorkshire, Englandd. 28 October 1792 Austhorpe, near Leeds, Yorkshire, England[br]English mechanical and civil engineer.[br]As a boy, Smeaton showed mechanical ability, making for himself a number of tools and models. This practical skill was backed by a sound education, probably at Leeds Grammar School. At the age of 16 he entered his father's office; he seemed set to follow his father's profession in the law. In 1742 he went to London to continue his legal studies, but he preferred instead, with his father's reluctant permission, to set up as a scientific instrument maker and dealer and opened a shop of his own in 1748. About this time he began attending meetings of the Royal Society and presented several papers on instruments and mechanical subjects, being elected a Fellow in 1753. His interests were turning towards engineering but were informed by scientific principles grounded in careful and accurate observation.In 1755 the second Eddystone lighthouse, on a reef some 14 miles (23 km) off the English coast at Plymouth, was destroyed by fire. The President of the Royal Society was consulted as to a suitable engineer to undertake the task of constructing a new one, and he unhesitatingly suggested Smeaton. Work began in 1756 and was completed in three years to produce the first great wave-swept stone lighthouse. It was constructed of Portland stone blocks, shaped and pegged both together and to the base rock, and bonded by hydraulic cement, scientifically developed by Smeaton. It withstood the storms of the English Channel for over a century, but by 1876 erosion of the rock had weakened the structure and a replacement had to be built. The upper portion of Smeaton's lighthouse was re-erected on a suitable base on Plymouth Hoe, leaving the original base portion on the reef as a memorial to the engineer.The Eddystone lighthouse made Smeaton's reputation and from then on he was constantly in demand as a consultant in all kinds of engineering projects. He carried out a number himself, notably the 38 mile (61 km) long Forth and Clyde canal with thirty-nine locks, begun in 1768 but for financial reasons not completed until 1790. In 1774 he took charge of the Ramsgate Harbour works.On the mechanical side, Smeaton undertook a systematic study of water-and windmills, to determine the design and construction to achieve the greatest power output. This work issued forth as the paper "An experimental enquiry concerning the natural powers of water and wind to turn mills" and exerted a considerable influence on mill design during the early part of the Industrial Revolution. Between 1753 and 1790 Smeaton constructed no fewer than forty-four mills.Meanwhile, in 1756 he had returned to Austhorpe, which continued to be his home base for the rest of his life. In 1767, as a result of the disappointing performance of an engine he had been involved with at New River Head, Islington, London, Smeaton began his important study of the steam-engine. Smeaton was the first to apply scientific principles to the steam-engine and achieved the most notable improvements in its efficiency since its invention by Newcomen, until its radical overhaul by James Watt. To compare the performance of engines quantitatively, he introduced the concept of "duty", i.e. the weight of water that could be raised 1 ft (30 cm) while burning one bushel (84 lb or 38 kg) of coal. The first engine to embody his improvements was erected at Long Benton colliery in Northumberland in 1772, with a duty of 9.45 million pounds, compared to the best figure obtained previously of 7.44 million pounds. One source of heat loss he attributed to inaccurate boring of the cylinder, which he was able to improve through his close association with Carron Ironworks near Falkirk, Scotland.[br]Principal Honours and DistinctionsFRS 1753.Bibliography1759, "An experimental enquiry concerning the natural powers of water and wind to turn mills", Philosophical Transactions of the Royal Society.Towards the end of his life, Smeaton intended to write accounts of his many works but only completed A Narrative of the Eddystone Lighthouse, 1791, London.Further ReadingS.Smiles, 1874, Lives of the Engineers: Smeaton and Rennie, London.

37 Walschaert, Egide
SUBJECT AREA: Steam and internal combustion engines[br]b. 20 January 1820 Mechlin, Belgiumd. 18 February 1901 Saint-Lilies, Brussels, Belgium[br]Belgian inventor of Walschaerrt valve gear for steam engines.[br]Walschaert was appointed Foreman of the Brussels Midi workshops of the Belgian State Railways in 1844, when they were opened, and remained in this position until 1885. He invented his valve gear the year he took up his appointment and was allowed to fit it to a 2–2–2 locomotive in 1848, the results being excellent. It was soon adopted in Belgium and to a lesser extent in France, but although it offered accessibility, light weight and mechanical efficiency, railways elsewhere were remarkably slow to take it up. It was first used in the British Isles in 1878, on a 0–4–4 tank locomotive built to the patent of Robert Fairlie, but was not used again there until 1890. By contrast, Fairlie had already used Walchaert's valve gear in 1873, on locomotives for New Zealand, and when New Zealand Railways started to build their own locomotives in 1889 they perpetuated it. The valve gear was only introduced to the USA following a visit by an executive of the Baldwin Locomotive Works to New Zealand ten years later. Subsequently it came to be used almost everywhere there were steam locomotives. Walschaert himself invented other improvements for steam engines, but none with lasting effect.[br]Further ReadingP.Ransome-Wallis (ed.), 1959, The Concise Encyclopaedia, of World Railway Locomotives, London: Hutchinson (includes both a brief biography of Walschaert (p.502) and a technical description of his valve gear (p. 298)).E.L.Ahrons, 1927, The British Steam Railway Locomotive 1825–1925, London: The Locomotive Publishing Co., pp. 224 and 289 (describes the introduction of the valve gear to Britain).J.B.Snell, 1964, Early Railways, London: Weidenfeld \& Nicolson, 103.PJGR -
