  • 3 Brunel, Isambard Kingdom

    [br]
    b. 9 April 1806 Portsea, Hampshire, England
    d. 15 September 1859 18 Duke Street, St James's, London, England
    [br]
    English civil and mechanical engineer.
    [br]
    The son of Marc Isambard Brunel and Sophia Kingdom, he was educated at a private boarding-school in Hove. At the age of 14 he went to the College of Caen and then to the Lycée Henri-Quatre in Paris, after which he was apprenticed to Louis Breguet. In 1822 he returned from France and started working in his father's office, while spending much of his time at the works of Maudslay, Sons \& Field.
    From 1825 to 1828 he worked under his father on the construction of the latter's Thames Tunnel, occupying the position of Engineer-in-Charge, exhibiting great courage and presence of mind in the emergencies which occurred not infrequently. These culminated in January 1828 in the flooding of the tunnel and work was suspended for seven years. For the next five years the young engineer made abortive attempts to find a suitable outlet for his talents, but to little avail. Eventually, in 1831, his design for a suspension bridge over the River Avon at Clifton Gorge was accepted and he was appointed Engineer. (The bridge was eventually finished five years after Brunel's death, as a memorial to him, the delay being due to inadequate financing.) He next planned and supervised improvements to the Bristol docks. In March 1833 he was appointed Engineer of the Bristol Railway, later called the Great Western Railway. He immediately started to survey the route between London and Bristol that was completed by late August that year. On 5 July 1836 he married Mary Horsley and settled into 18 Duke Street, Westminster, London, where he also had his office. Work on the Bristol Railway started in 1836. The foundation stone of the Clifton Suspension Bridge was laid the same year. Whereas George Stephenson had based his standard railway gauge as 4 ft 8½ in (1.44 m), that or a similar gauge being usual for colliery wagonways in the Newcastle area, Brunel adopted the broader gauge of 7 ft (2.13 m). The first stretch of the line, from Paddington to Maidenhead, was opened to traffic on 4 June 1838, and the whole line from London to Bristol was opened in June 1841. The continuation of the line through to Exeter was completed and opened on 1 May 1844. The normal time for the 194-mile (312 km) run from Paddington to Exeter was 5 hours, at an average speed of 38.8 mph (62.4 km/h) including stops. The Great Western line included the Box Tunnel, the longest tunnel to that date at nearly two miles (3.2 km).
    Brunel was the engineer of most of the railways in the West Country, in South Wales and much of Southern Ireland. As railway networks developed, the frequent break of gauge became more of a problem and on 9 July 1845 a Royal Commission was appointed to look into it. In spite of comparative tests, run between Paddington-Didcot and Darlington-York, which showed in favour of Brunel's arrangement, the enquiry ruled in favour of the narrow gauge, 274 miles (441 km) of the former having been built against 1,901 miles (3,059 km) of the latter to that date. The Gauge Act of 1846 forbade the building of any further railways in Britain to any gauge other than 4 ft 8 1/2 in (1.44 m).
    The existence of long and severe gradients on the South Devon Railway led to Brunel's adoption of the atmospheric railway developed by Samuel Clegg and later by the Samuda brothers. In this a pipe of 9 in. (23 cm) or more in diameter was laid between the rails, along the top of which ran a continuous hinged flap of leather backed with iron. At intervals of about 3 miles (4.8 km) were pumping stations to exhaust the pipe. Much trouble was experienced with the flap valve and its lubrication—freezing of the leather in winter, the lubricant being sucked into the pipe or eaten by rats at other times—and the experiment was abandoned at considerable cost.
    Brunel is to be remembered for his two great West Country tubular bridges, the Chepstow and the Tamar Bridge at Saltash, with the latter opened in May 1859, having two main spans of 465 ft (142 m) and a central pier extending 80 ft (24 m) below high water mark and allowing 100 ft (30 m) of headroom above the same. His timber viaducts throughout Devon and Cornwall became a feature of the landscape. The line was extended ultimately to Penzance.
    As early as 1835 Brunel had the idea of extending the line westwards across the Atlantic from Bristol to New York by means of a steamship. In 1836 building commenced and the hull left Bristol in July 1837 for fitting out at Wapping. On 31 March 1838 the ship left again for Bristol but the boiler lagging caught fire and Brunel was injured in the subsequent confusion. On 8 April the ship set sail for New York (under steam), its rival, the 703-ton Sirius, having left four days earlier. The 1,340-ton Great Western arrived only a few hours after the Sirius. The hull was of wood, and was copper-sheathed. In 1838 Brunel planned a larger ship, some 3,000 tons, the Great Britain, which was to have an iron hull.
    The Great Britain was screwdriven and was launched on 19 July 1843,289 ft (88 m) long by 51 ft (15.5 m) at its widest. The ship's first voyage, from Liverpool to New York, began on 26 August 1845. In 1846 it ran aground in Dundrum Bay, County Down, and was later sold for use on the Australian run, on which it sailed no fewer than thirty-two times in twenty-three years, also serving as a troop-ship in the Crimean War. During this war, Brunel designed a 1,000-bed hospital which was shipped out to Renkioi ready for assembly and complete with shower-baths and vapour-baths with printed instructions on how to use them, beds and bedding and water closets with a supply of toilet paper! Brunel's last, largest and most extravagantly conceived ship was the Great Leviathan, eventually named The Great Eastern, which had a double-skinned iron hull, together with both paddles and screw propeller. Brunel designed the ship to carry sufficient coal for the round trip to Australia without refuelling, thus saving the need for and the cost of bunkering, as there were then few bunkering ports throughout the world. The ship's construction was started by John Scott Russell in his yard at Millwall on the Thames, but the building was completed by Brunel due to Russell's bankruptcy in 1856. The hull of the huge vessel was laid down so as to be launched sideways into the river and then to be floated on the tide. Brunel's plan for hydraulic launching gear had been turned down by the directors on the grounds of cost, an economy that proved false in the event. The sideways launch with over 4,000 tons of hydraulic power together with steam winches and floating tugs on the river took over two months, from 3 November 1857 until 13 January 1858. The ship was 680 ft (207 m) long, 83 ft (25 m) beam and 58 ft (18 m) deep; the screw was 24 ft (7.3 m) in diameter and paddles 60 ft (18.3 m) in diameter. Its displacement was 32,000 tons (32,500 tonnes).
    The strain of overwork and the huge responsibilities that lay on Brunel began to tell. He was diagnosed as suffering from Bright's disease, or nephritis, and spent the winter travelling in the Mediterranean and Egypt, returning to England in May 1859. On 5 September he suffered a stroke which left him partially paralysed, and he died ten days later at his Duke Street home.

  • 4 Bollée, Ernest-Sylvain

    [br]
    b. 19 July 1814 Clefmont (Haute-Marne), France
    d. 11 September 1891 Le Mans, France
    [br]
    French inventor of the rotor-stator wind engine and founder of the Bollée manufacturing industry.
    [br]
    Ernest-Sylvain Bollée was the founder of an extensive dynasty of bellfounders based in Le Mans and in Orléans. He and his three sons, Amédée (1844–1917), Ernest-Sylvain fils (1846–1917) and Auguste (1847-?), were involved in work and patents on steam-and petrol-driven cars, on wind engines and on hydraulic rams. The presence of the Bollées' car industry in Le Mans was a factor in the establishment of the car races that are held there.
    In 1868 Ernest-Sylvain Bollée père took out a patent for a wind engine, which at that time was well established in America and in England. In both these countries, variable-shuttered as well as fixed-blade wind engines were in production and patented, but the Ernest-Sylvain Bollée patent was for a type of wind engine that had not been seen before and is more akin to the water-driven turbine of the Jonval type, with its basic principle being parallel to the "rotor" and "stator". The wind drives through a fixed ring of blades on to a rotating ring that has a slightly greater number of blades. The blades of the fixed ring are curved in the opposite direction to those on the rotating blades and thus the air is directed onto the latter, causing it to rotate at a considerable speed: this is the "rotor". For greater efficiency a cuff of sheet iron can be attached to the "stator", giving a tunnel effect and driving more air at the "rotor". The head of this wind engine is turned to the wind by means of a wind-driven vane mounted in front of the blades. The wind vane adjusts the wind angle to enable the wind engine to run at a constant speed.
    The fact that this wind engine was invented by the owner of a brass foundry, with all the gear trains between the wind vane and the head of the tower being of the highest-quality brass and, therefore, small in scale, lay behind its success. Also, it was of prefabricated construction, so that fixed lengths of cast-iron pillar were delivered, complete with twelve treads of cast-iron staircase fixed to the outside and wrought-iron stays. The drive from the wind engine was taken down the inside of the pillar to pumps at ground level.
    Whilst the wind engines were being built for wealthy owners or communes, the work of the foundry continued. The three sons joined the family firm as partners and produced several steam-driven vehicles. These vehicles were the work of Amédée père and were l'Obéissante (1873); the Autobus (1880–3), of which some were built in Berlin under licence; the tram Bollée-Dalifol (1876); and the private car La Mancelle (1878). Another important line, in parallel with the pumping mechanism required for the wind engines, was the development of hydraulic rams, following the Montgolfier patent. In accordance with French practice, the firm was split three ways when Ernest-Sylvain Bollée père died. Amédée père inherited the car side of the business, but it is due to Amédée fils (1867– 1926) that the principal developments in car manufacture came into being. He developed the petrol-driven car after the impetus given by his grandfather, his father and his uncle Ernest-Sylvain fils. In 1887 he designed a four-stroke single-cylinder engine, although he also used engines designed by others such as Peugeot. He produced two luxurious saloon cars before putting Torpilleur on the road in 1898; this car competed in the Tour de France in 1899. Whilst designing other cars, Amédée's son Léon (1870–1913) developed the Voiturette, in 1896, and then began general manufacture of small cars on factory lines. The firm ceased work after a merger with the English firm of Morris in 1926. Auguste inherited the Eolienne or wind-engine side of the business; however, attracted to the artistic life, he sold out to Ernest Lebert in 1898 and settled in the Paris of the Impressionists. Lebert developed the wind-engine business and retained the basic "stator-rotor" form with a conventional lattice tower. He remained in Le Mans, carrying on the business of the manufacture of wind engines, pumps and hydraulic machinery, describing himself as a "Civil Engineer".
    The hydraulic-ram business fell to Ernest-Sylvain fils and continued to thrive from a solid base of design and production. The foundry in Le Mans is still there but, more importantly, the bell foundry of Dominique Bollée in Saint-Jean-de-Braye in Orléans is still at work casting bells in the old way.

    [br]
    American mechanical engineer.
    [br]
    The son of a lawyer, he entered an academy in Cape Cod and, at the age of 19, the English Academy at Andover, Massachusetts, for five terms. He was then in the employ of Samuel L. Fenton of Charlestown, Massachusetts. He served a three-year apprenticeship, then went to the Windsor White River Division of the Vermont Central Railroad. He was Resident Engineer of the Cheshire Railroad at Walpote, New Hampshire, from 1847 to 1849, and then worked in independent practice as a civil engineer and surveyor until his death. He was involved with nearly all the railroads running out of Boston, especially the Boston \& Maine. In April 1863 he was appointed Chief Engineer of the Hoosac Tunnel, which was already being built. He introduced new engineering methods, relocated the line of the tunnel and achieved great accuracy in the meeting of the borings. He was largely responsible for the development in the USA of the advanced system of tunnelling with machinery and explosives, and pioneered the use of compressed air in the USA. In 1869 he was Chief Engineer of the Burlington \& Missouri River Railroad in Nebraska, laying down some 240 miles (386 km) of track in four years. During this period he became interested in the building of a Congregational College at Crete, Nebraska, for which he gave the land and which was named after him. In 1873 he returned to Charlestown and was again appointed Chief Engineer of the Hoosac Tunnel. At the final opening of the tunnel on 9 February 1875 he drove the first engine through. He remained in charge of construction for a further two years.

    [br]
    b. 3 September 1846 Hamburg, Germany
    d. 29 November 1899 Brig, Switzerland
    [br]
    German mechanical engineer, developer of a hydraulic rock drill.
    [br]
    The son of a Hamburg merchant, he studied mechanical engineering at the Polytechnikum in Zurich and was engaged in constructing a railway line in Hungary and Austria before he returned to Switzerland. At Airolo, where the Gotthard tunnel was to commence, he designed a hydraulic rock drill; the pneumatic ones, similar to the Ingersoll type, did not satisfy him. His drill consisted of two parts instead of three: the hydraulic motor and the installation for drilling. At the Sulzer company of Winterthur his first design, a percussion drill, in 1876, was developed into a rotary drill which worked with greatest success in the construction of various railway tunnels and also helped to reduce costs in the mining industry.
    His Hamburg-based firm Brandt \& Brandau consequently was soon engaged in many tunnelling and mining projects throughout Germany, as well as abroad. During the years 1883 and 1895 Brandt spent time in exploration in Spain and reopening the lead-mines in Posada. His most ambitious task was to co-operate in drafting the Simplon tunnel, the construction of which relied greatly on his knowledge and expertise. The works began several years behind schedule, in 1898, and consequently he was unable to see its completion.

  • 8 Crampton, Thomas Russell

    [br]
    b. 6 August 1816 Broadstairs, Kent, England
    d. 19 April 1888 London, England
    [br]
    English engineer, pioneer of submarine electric telegraphy and inventor of the Crampton locomotive.
    [br]
    After private education and an engineering apprenticeship, Crampton worked under Marc Brunel, Daniel Gooch and the Rennie brothers before setting up as a civil engineer in 1848. His developing ideas on locomotive design were expressed through a series of five patents taken out between 1842 and 1849, each making a multiplicity of claims. The most typical feature of the Crampton locomotive, however, was a single pair of driving wheels set to the rear of the firebox. This meant they could be of large diameter, while the centre of gravity of the locomotive remained low, for the boiler barrel, though large, had only small carrying-wheels beneath it. The cylinders were approximately midway along the boiler and were outside the frames, as was the valve gear. The result was a steady-riding locomotive which neither pitched about a central driving axle nor hunted from side to side, as did other contemporary locomotives, and its working parts were unusually accessible for maintenance. However, adhesive weight was limited and the long wheelbase tended to damage track. Locomotives of this type were soon superseded on British railways, although they lasted much longer in Germany and France. Locomotives built to the later patents incorporated a long, coupled wheelbase with drive through an intermediate crankshaft, but they mostly had only short lives. In 1851 Crampton, with associates, laid the first successful submarine electric telegraph cable. The previous year the brothers Jacob and John Brett had laid a cable, comprising a copper wire insulated with gutta-percha, beneath the English Channel from Dover to Cap Gris Nez: signals were passed but within a few hours the cable failed. Crampton joined the Bretts' company, put up half the capital needed for another attempt, and designed a much stronger cable. Four gutta-percha-insulated copper wires were twisted together, surrounded by tarred hemp and armoured by galvanized iron wires; this cable was successful.
    Crampton was also active in railway civil engineering and in water and gas engineering, and c. 1882 he invented a hydraulic tunnel-boring machine intended for a Channel tunnel.

    [br]
    b. late 18th century Finchley (?), London, England
    d. mid-19th century probably New York, USA
    [br]
    English contributor to investigations into the making of hydraulic cements in the early nineteenth century.
    [br]
    As early as 1807 Frost, who was originally a builder and bricklayer in Finchley in north London, was manufacturing Roman Cement, patented by James Parker in 1796, in the Harwich area and a similar cement further south, at Sheerness. In the early 1820s Frost visited Louis J.Vicat (1796–1861) in France. Vicat was a French engineer who began in 1812 a detailed investigation into the properties of various limestones found in France. He later published his conclusions, which were that the best hydraulic lime was that produced from limestone containing clay incorporating silica and alumina. He experimented with adding different clays in varying proportions to slaked lime and calcined the mixture. Benefiting from Vicat's research, Frost obtained a patent in 1822 for what he called British Cement. This patent specified an artificial cement made from limestone and silica, and he calcined chalk with the clay to produce a quick-setting product. This was made at Swanscombe near Northfleet on the south bank of the River Thames. In 1833 the Swanscombe manufactory was purchased by Francis \& White for £3,500 and Frost emigrated to America, setting up practice as a civil engineer in New York. The cement was utilized by Sir Marc Brunel in 1835 in his construction of the Thames Tunnel, and at the same time it was used in building the first all-concrete house at Swanscombe for Mr White.

    Trevithick's father was a tin-mine manager, and Trevithick himself, after limited formal education, developed his immense engineering talent among local mining machinery and steam-engines and found employment as a mining engineer. Tall, strong and high-spirited, he was the eternal optimist.
    About 1797 it occurred to him that the separate condenser patent of James Watt could be avoided by employing "strong steam", that is steam at pressures substantially greater than atmospheric, to drive steam-engines: after use, steam could be exhausted to the atmosphere and the condenser eliminated. His first winding engine on this principle came into use in 1799, and subsequently such engines were widely used. To produce high-pressure steam, a stronger boiler was needed than the boilers then in use, in which the pressure vessel was mounted upon masonry above the fire: Trevithick designed the cylindrical boiler, with furnace tube within, from which the Cornish and later the Lancashire boilers evolved.
    Simultaneously he realized that high-pressure steam enabled a compact steam-engine/boiler unit to be built: typically, the Trevithick engine comprised a cylindrical boiler with return firetube, and a cylinder recessed into the boiler. No beam intervened between connecting rod and crank. A master patent was taken out.
    Such an engine was well suited to driving vehicles. Trevithick built his first steam-carriage in 1801, but after a few days' use it overturned on a rough Cornish road and was damaged beyond repair by fire. Nevertheless, it had been the first self-propelled vehicle successfully to carry passengers. His second steam-carriage was driven about the streets of London in 1803, even more successfully; however, it aroused no commercial interest. Meanwhile the Coalbrookdale Company had started to build a locomotive incorporating a Trevithick engine for its tramroads, though little is known of the outcome; however, Samuel Homfray's ironworks at Penydarren, South Wales, was already building engines to Trevithick's design, and in 1804 Trevithick built one there as a locomotive for the Penydarren Tramroad. In this, and in the London steam-carriage, exhaust steam was turned up the chimney to draw the fire. On 21 February the locomotive hauled five wagons with 10 tons of iron and seventy men for 9 miles (14 km): it was the first successful railway locomotive.
    Again, there was no commercial interest, although Trevithick now had nearly fifty stationary engines completed or being built to his design under licence. He experimented with one to power a barge on the Severn and used one to power a dredger on the Thames. He became Engineer to a project to drive a tunnel beneath the Thames at Rotherhithe and was only narrowly defeated, by quicksands. Trevithick then set up, in 1808, a circular tramroad track in London and upon it demonstrated to the admission-fee-paying public the locomotive Catch me who can, built to his design by John Hazledine and J.U. Rastrick.
    In 1809, by which date Trevithick had sold all his interest in the steam-engine patent, he and Robert Dickinson, in partnership, obtained a patent for iron tanks to hold liquid cargo in ships, replacing the wooden casks then used, and started to manufacture them. In 1810, however, he was taken seriously ill with typhus for six months and had to return to Cornwall, and early in 1811 the partners were bankrupt; Trevithick was discharged from bankruptcy only in 1814.
    In the meantime he continued as a steam engineer and produced a single-acting steam engine in which the cut-off could be varied to work the engine expansively by way of a three-way cock actuated by a cam. Then, in 1813, Trevithick was approached by a representative of a company set up to drain the rich but flooded silver-mines at Cerro de Pasco, Peru, at an altitude of 14,000 ft (4,300 m). Low-pressure steam engines, dependent largely upon atmospheric pressure, would not work at such an altitude, but Trevithick's high-pressure engines would. Nine engines and much other mining plant were built by Hazledine and Rastrick and despatched to Peru in 1814, and Trevithick himself followed two years later. However, the war of independence was taking place in Peru, then a Spanish colony, and no sooner had Trevithick, after immense difficulties, put everything in order at the mines then rebels arrived and broke up the machinery, for they saw the mines as a source of supply for the Spanish forces. It was only after innumerable further adventures, during which he encountered and was assisted financially by Robert Stephenson, that Trevithick eventually arrived home in Cornwall in 1827, penniless.
    He petitioned Parliament for a grant in recognition of his improvements to steam-engines and boilers, without success. He was as inventive as ever though: he proposed a hydraulic power transmission system; he was consulted over steam engines for land drainage in Holland; and he suggested a 1,000 ft (305 m) high tower of gilded cast iron to commemorate the Reform Act of 1832. While working on steam propulsion of ships in 1833, he caught pneumonia, from which he died.
