3 Fairbairn, Sir Peter
SUBJECT AREA: Textiles[br]b. September 1799 Kelso, Roxburghshire, Scotlandd. 4 January 1861 Leeds, Yorkshire, England[br]British inventor of the revolving tube between drafting rollers to give false twist.[br]Born of Scottish parents, Fairbairn was apprenticed at the age of 14 to John Casson, a mill-wright and engineer at the Percy Main Colliery, Newcastle upon Tyne, and remained there until 1821 when he went to work for his brother William in Manchester. After going to various other places, including Messrs Rennie in London and on the European continent, he eventually moved in 1829 to Leeds where Marshall helped him set up the Wellington Foundry and so laid the foundations for the colossal establishment which was to employ over one thousand workers. To begin with he devoted his attention to improving wool-weaving machinery, substituting iron for wood in the construction of the textile machines. He also worked on machinery for flax, incorporating many of Philippe de Girard's ideas. He assisted Henry Houldsworth in the application of the differential to roving frames, and it was to these machines that he added his own inventions. The longer fibres of wool and flax need to have some form of support and control between the rollers when they are being drawn out, and inserting a little twist helps. However, if the roving is too tightly twisted before passing through the first pair of rollers, it cannot be drawn out, while if there is insufficient twist, the fibres do not receive enough support in the drafting zone. One solution is to twist the fibres together while they are actually in the drafting zone between the rollers. In 1834, Fairbairn patented an arrangement consisting of a revolving tube placed between the drawing rollers. The tube inserted a "middle" or "false" twist in the material. As stated in the specification, it was "a well-known contrivance… for twisting and untwisting any roving passing through it". It had been used earlier in 1822 by J. Goulding of the USA and a similar idea had been developed by C.Danforth in America and patented in Britain in 1825 by J.C. Dyer. Fairbairn's machine, however, was said to make a very superior article. He was also involved with waste-silk spinning and rope-yarn machinery.Fairbairn later began constructing machine tools, and at the beginning of the Crimean War was asked by the Government to make special tools for the manufacture of armaments. He supplied some of these, such as cannon rifling machines, to the arsenals at Woolwich and Enfield. He then made a considerable number of tools for the manufacture of the Armstrong gun. He was involved in the life of his adopted city and was elected to Leeds town council in 1832 for ten years. He was elected an alderman in 1854 and was Mayor of Leeds from 1857 to 1859, when he was knighted by Queen Victoria at the opening of the new town hall. He was twice married, first to Margaret Kennedy and then to Rachel Anne Brindling.[br]Principal Honours and DistinctionsKnighted 1858.Bibliography1834, British patent no. 6,741 (revolving tube between drafting rollers to give false twist).Further ReadingDictionary of National Biography.Obituary, 1861, Engineer 11.W.English, 1969, The Textile Industry, London (provides a brief account of Fairbairn's revolving tube).C.Singer (ed.), 1958, A History of Technology, Vols IV and V, Oxford: Clarendon Press (provides details of Fairbairn's silk-dressing machine and a picture of a large planing machine built by him).RLH -
4 Brunel, Isambard Kingdom
SUBJECT AREA: Civil engineering, Land transport, Mechanical, pneumatic and hydraulic engineering, Ports and shipping, Public utilities, Railways and locomotives[br]b. 9 April 1806 Portsea, Hampshire, Englandd. 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.[br]Further ReadingL.T.C.Rolt, 1957, Isambard Kingdom Brunel, London: Longmans Green.
