4 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 -
5 Séguin, Louis
[br]b. 1869d. 1918[br]French co-designer, with his brother Laurent Séguin (b. 1883 Rhône, France; d. 1944), of the extremely successful Gnome rotary engines.[br]Most early aero-engines were adaptations of automobile engines, but Louis Séguin and his brother Laurent set out to produce a genuine aero-engine. They decided to build a "rotary" engine in which the crankshaft remained stationary and the cylinders rotated: the propeller was attached to the cylinders. The idea was not new, for rotary engines had been proposed by engineers from James Watt to Samuel P. Langley, rival of the Wright brothers. (An engine with stationary cylinders and a rotating crankshaftplus-propeller is classed as a "radial".) Louis Séguin formed the Société des Moteurs Gnome in 1906 to build stationary industrial engines. Laurent joined him to develop a lightweight engine specifically for aeronautical use. They built a fivecylinder air-cooled radial engine in 1908 and then a prototype seven-cylinder rotary engine. Later in the year the Gnome Oméga rotary, developing 50 hp (37 kW), was produced. This was test-flown in a Voisin biplane during June 1909. The Gnome was much lighter than its conventional rivals and surprisingly reliable in view of the technical problems of supplying rotating cylinders with the petrol-air mixture and a spark to ignite it. It was an instant success.Gnomes were mass-produced for use during the First World War. Both sides built and flew rotary engines, which were improved over the years until, by 1917, their size had grown to such an extent that a further increase was not practicable. The gyroscopic effects of a large rotating engine became a serious handicap to manoeuvrability, and the technical problems inherent in a rotary engine were accentuated.[br]Bibliography1912, L'Aérophile 20(4) (Louis Séguin's description of the Gnome).Further ReadingC.F.Taylor, 1971, "Aircraft Propulsion", Smithsonian Annals of Flight 1(4) (an account of the evolution of aircraft piston engines).A.Nahum, 1987, the Rotary Aero-Engine, London.JDS -

18 Booth, Henry
[br]b. 4 April 1789 Liverpool, Englandd. 28 March 1869 Liverpool, England[br]English railway administrator and inventor.[br]Booth followed his father as a Liverpool corn merchant but had great mechanical aptitude. In 1824 he joined the committee for the proposed Liverpool \& Manchester Railway (L \& MR) and after the company obtained its Act of Parliament in 1826 he was appointed Treasurer.In 1829 the L \& MR announced a prize competition, the Rainhill Trials, for an improved steam locomotive: Booth, realizing that the power of a locomotive depended largely upon its capacity to raise steam, had the idea that this could be maximized by passing burning gases from the fire through the boiler in many small tubes to increase the heating surface, rather than in one large one, as was then the practice. He was apparently unaware of work on this type of boiler even then being done by Marc Seguin, and the 1791 American patent by John Stevens. Booth discussed his idea with George Stephenson, and a boiler of this type was incorporated into the locomotive Rocket, which was built by Robert Stephenson and entered in the Trials by Booth and the two Stephensons in partnership. The boiler enabled Rocket to do all that was required in the trials, and far more: it became the prototype for all subsequent conventional locomotive boilers.After the L \& MR opened in 1830, Booth as Treasurer became in effect the general superintendent and was later General Manager. He invented screw couplings for use with sprung buffers. When the L \& MR was absorbed by the Grand Junction Railway in 1845 he became Secretary of the latter, and when, later the same year, that in turn amalgamated with the London \& Birmingham Railway (L \& BR) to form the London \& North Western Railway (L \& NWR), he became joint Secretary with Richard Creed from the L \& BR.Earlier, completion in 1838 of the railway from London to Liverpool had brought problems with regard to local times. Towns then kept their own time according to their longitude: Birmingham time, for instance, was 7¼ minutes later than London time. This caused difficulties in railway operation, so Booth prepared a petition to Parliament on behalf of the L \& MR that London time should be used throughout the country, and in 1847 the L \& NWR, with other principal railways and the Post Office, adopted Greenwich time. It was only in 1880, however, that the arrangement was made law by Act of Parliament.[br]Bibliography1835. British patent no. 6,814 (grease lubricants for axleboxes). 1836. British patent no. 6,989 (screw couplings).Booth also wrote several pamphlets on railways, uniformity of time, and political matters.Further ReadingH.Booth, 1980, Henry Booth, Ilfracombe: Arthur H.Stockwell (a good full-length biography, the author being the great-great-nephew of his subject; with bibliography).R.E.Carlson, 1969, The Liverpool \& Manchester Railway Project 1821–1831, Newton Abbot: David \& Charles.PJGR -

20 Stephenson, Robert
[br]b. 16 October 1803 Willington Quay, Northumberland, Englandd. 12 October 1859 London, England[br]English engineer who built the locomotive Rocket and constructed many important early trunk railways.[br]Robert Stephenson's father was George Stephenson, who ensured that his son was educated to obtain the theoretical knowledge he lacked himself. In 1821 Robert Stephenson assisted his father in his survey of the Stockton \& Darlington Railway and in 1822 he assisted William James in the first survey of the Liverpool \& Manchester Railway. He then went to Edinburgh University for six months, and the following year Robert Stephenson \& Co. was named after him as Managing Partner when it was formed by himself, his father and others. The firm was to build stationary engines, locomotives and railway rolling stock; in its early years it also built paper-making machinery and did general engineering.In 1824, however, Robert Stephenson accepted, perhaps in reaction to an excess of parental control, an invitation by a group of London speculators called the Colombian Mining Association to lead an expedition to South America to use steam power to reopen gold and silver mines. He subsequently visited North America before returning to England in 1827 to rejoin his father as an equal and again take charge of Robert Stephenson \& Co. There he set about altering the design of steam locomotives to improve both their riding and their steam-generating capacity. Lancashire Witch, completed in July 1828, was the first locomotive mounted on steel springs and had twin furnace tubes through the boiler to produce a large heating surface. Later that year Robert Stephenson \& Co. supplied the Stockton \& Darlington Railway with a wagon, mounted for the first time on springs and with outside bearings. It was to be the prototype of the standard British railway wagon. Between April and September 1829 Robert Stephenson built, not without difficulty, a multi-tubular boiler, as suggested by Henry Booth to George Stephenson, and incorporated it into the locomotive Rocket which the three men entered in the Liverpool \& Manchester Railway's Rainhill Trials in October. Rocket, was outstandingly successful and demonstrated that the long-distance steam railway was practicable.Robert Stephenson continued to develop the locomotive. Northumbrian, built in 1830, had for the first time, a smokebox at the front of the boiler and also the firebox built integrally with the rear of the boiler. Then in Planet, built later the same year, he adopted a layout for the working parts used earlier by steam road-coach pioneer Goldsworthy Gurney, placing the cylinders, for the first time, in a nearly horizontal position beneath the smokebox, with the connecting rods driving a cranked axle. He had evolved the definitive form for the steam locomotive.Also in 1830, Robert Stephenson surveyed the London \& Birmingham Railway, which was authorized by Act of Parliament in 1833. Stephenson became Engineer for construction of the 112-mile (180 km) railway, probably at that date the greatest task ever undertaken in of civil engineering. In this he was greatly assisted by G.P.Bidder, who as a child prodigy had been known as "The Calculating Boy", and the two men were to be associated in many subsequent projects. On the London \& Birmingham Railway there were long and deep cuttings to be excavated and difficult tunnels to be bored, notoriously at Kilsby. The line was opened in 1838.In 1837 Stephenson provided facilities for W.F. Cooke to make an experimental electrictelegraph installation at London Euston. The directors of the London \& Birmingham Railway company, however, did not accept his recommendation that they should adopt the electric telegraph and it was left to I.K. Brunel to instigate the first permanent installation, alongside the Great Western Railway. After Cooke formed the Electric Telegraph Company, Stephenson became a shareholder and was Chairman during 1857–8.Earlier, in the 1830s, Robert Stephenson assisted his father in advising on railways in Belgium and came to be increasingly in demand as a consultant. In 1840, however, he was almost ruined financially as a result of the collapse of the Stanhope \& Tyne Rail Road; in return for acting as Engineer-in-Chief he had unwisely accepted shares, with unlimited liability, instead of a fee.During the late 1840s Stephenson's greatest achievements were the design and construction of four great bridges, as part of railways for which he was responsible. The High Level Bridge over the Tyne at Newcastle and the Royal Border Bridge over the Tweed at Berwick were the links needed to complete the East Coast Route from London to Scotland. For the Chester \& Holyhead Railway to cross the Menai Strait, a bridge with spans as long-as 460 ft (140 m) was needed: Stephenson designed them as wrought-iron tubes of rectangular cross-section, through which the trains would pass, and eventually joined the spans together into a tube 1,511 ft (460 m) long from shore to shore. Extensive testing was done beforehand by shipbuilder William Fairbairn to prove the method, and as a preliminary it was first used for a 400 ft (122 m) span bridge at Conway.In 1847 Robert Stephenson was elected MP for Whitby, a position he held until his death, and he was one of the exhibition commissioners for the Great Exhibition of 1851. In the early 1850s he was Engineer-in-Chief for the Norwegian Trunk Railway, the first railway in Norway, and he also built the Alexandria \& Cairo Railway, the first railway in Africa. This included two tubular bridges with the railway running on top of the tubes. The railway was extended to Suez in 1858 and for several years provided a link in the route from Britain to India, until superseded by the Suez Canal, which Stephenson had opposed in Parliament. The greatest of all his tubular bridges was the Victoria Bridge across the River St Lawrence at Montreal: after inspecting the site in 1852 he was appointed Engineer-in-Chief for the bridge, which was 1 1/2 miles (2 km) long and was designed in his London offices. Sadly he, like Brunel, died young from self-imposed overwork, before the bridge was completed in 1859.[br]Principal Honours and DistinctionsFRS 1849.
