  • 1 Unwin, William Cawthorne

    [br]
    b. 12 December 1838 Coggeshall, near Colchester, Essex, England d. 1933
    [br]
    English engineer and educator.
    [br]
    Unwin made an important contribution to the establishment of engineering at the University of London. His family were of Huguenot stock, and his father was a Congregational minister. Unwin was educated at the City of London Corporation School and at New College, St John's Wood. At a time when the older universities were still effectively closed to Dissenters, he matriculated with Honours in Chemistry in the London University Matriculation Examination in 1858, and he subsequently graduated BSc from London in 1861. He served as Scientific Assistant to William Fairbairn in Manchester from 1856 to 1862, going on to manage engineering work of various sorts. He was appointed Instructor at the Royal School of Naval Architecture and Marine Engineering (1869–72), and then he became Professor of Hydraulics and Mechanical Engineering at the Royal Indian Engineering College (1872–84). From 1884 to 1904 he was Professor of Civil and Mechanical Engineering at the Central Institution of the City \& Guilds of London, which was incorporated into the University of London in 1900. Unwin's research interests included hydraulics and water power, which led to him taking a leading part in the Niagara Falls hydroelectric scheme; the strength of materials, involving the stability of masonry dams; and the development of the internal combustion engine.

    SUBJECT AREA: Civil engineering
    [br]
    b. 1848 Scotland
    d. 4 September 1918
    [br]
    Scottish engineer and educator.
    [br]
    Henry Dyer was educated at Andersen's College and Glasgow University. He was apprenticed to the Glasgow marine engineer Alexander Kirk, and in 1870 he became an early holder of a Whitworth Scholarship. He was recruited at the age of 24 to establish the Tokyo Engineers' College in 1873. He had been recommended to Matheson, the Scottish businessman who was acting for the Japanese government, by W.J.M. Rankine of Glasgow University, who regarded Dyer as one of his most outstanding students. Dyer secured the services of a team of able young British engineers and scientists to staff the college, which opened in 1873 with 56 students and became the Imperial College of Engineering. Together they gave the first generation of Japanese engineers a firm grounding in engineering theory and practice. Dyer served as Principal and Professor of Civil and Mechanical Engineering. He left Tokyo in 1882 and returned to Britain. The remainder of his career was rather an anticlimax, although he became an active supporter of the technical education movement and was involved in the development of the Glasgow and West of Scotland Technical College, of which he was a Life Governor.

  • 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.

  • 5 Field, Joshua

    [br]
    b. 1786 Hackney, London, England
    d. 11 August 1863 Balham Hill, Surrey, England
    [br]
    English mechanical engineer, co-founder of the Institution of Civil Engineers.
    [br]
    Joshua Field was educated at a boarding school in Essex until the age of 16, when he obtained employment at the Royal Dockyards at Portsmouth under the Chief Mechanical Superintendent, Simon Goodrich (1773–1847), and later in the drawing office at the Admiralty in Whitehall. At this time, machinery for the manufacture of ships' blocks was being made for the Admiralty by Henry Maudslay, who was in need of a competent draughtsman, and Goodrich recommended Joshua Field. This was the beginning of Field's long association with Maudslay; he later became a partner in the firm which was for many years known as Maudslay, Sons \& Field. They undertook a variety of mechanical engineering work but were renowned for marine steam engines, with Field being responsible for much of the design work in the early years. Joshua Field was the eldest of the eight young men who in 1818 founded the Institution of Civil Engineers; he was the first Chairman of the Institution and later became a vice-president. He was the only one of the founders to be elected President and was the first mechanical engineer to hold that office. James Nasmyth in his autobiography relates that Joshua Field kept a methodical account of his technical discussions in a series of note books which were later indexed. Some of these diaries have survived, and extracts from the notes he made on a tour of the industrial areas of the Midlands and the North West in 1821 have been published.

  • 6 Bodmer, Johann Georg

    [br]
    b. 9 December 1786 Zurich, Switzerland
    d. 30 May 1864 Zurich, Switzerland
    [br]
    Swiss mechanical engineer and inventor.
    [br]
    John George Bodmer (as he was known in England) showed signs of great inventive ability even as a child. Soon after completing his apprenticeship to a local millwright, he set up his own work-shop at Zussnacht. One of his first inventions, in 1805, was a shell which exploded on impact. Soon after this he went into partnership with Baron d'Eichthal to establish a cotton mill at St Blaise in the Black Forest. Bodmer designed the water-wheels and all the machinery. A few years later they established a factory for firearms and Bodmer designed special machine tools and developed a system of interchangeable manufacture comparable with American developments at that time. More inventions followed, including a detachable bayonet for breech-loading rifles and a rifled, breech-loading cannon for 12 lb (5.4 kg) shells.
    Bodmer was appointed by the Grand Duke of Baden to the posts of Director General of the Government Iron Works and Inspector of Artillery. He left St Blaise in 1816 and entered completely into the service of the Grand Duke, but before taking up his duties he visited Britain for the first time and made an intensive five-month tour of textile mills, iron works, workshops and similar establishments.
    In 1821 he returned to Switzerland and was engaged in setting up cotton mills and other engineering works. In 1824 he went back to England, where he obtained a patent for his improvements in cotton machinery and set up a mill near Bolton incorporating his ideas. His health failing, he was obliged to return to Switzerland in 1828, but he was soon busy with engineering works there and in France. In 1833 he went to England again, first to Bolton and four years later to Manchester in partnership with H.H.Birley. In the next ten years he patented many more inventions in the fields of textile machinery, steam engines and machine tools. These included a balanced steam engine, a mechanical stoker, steam engine valve gear, gear-cutting machines and a circular planer or vertical lathe, anticipating machines of this type later developed in America by E.P. Bullard. The metric system was used in his workshops and in gearing calculations he introduced the concept of diametral pitch, which then became known as "Manchester Pitch". The balanced engine was built in stationary form and in two locomotives, but although their running was remarkably smooth the additional complication prevented their wider use.
    After the death of H.H.Birley in 1846, Bodmer removed to London until 1848, when he went to Austria. About 1860 he returned to his native town of Zurich. He remained actively engaged in all kinds of inventions up to the end of his life. He obtained fourteen British patents, each of which describes many inventions; two of these patents were extended beyond the normal duration of fourteen years. Two others were obtained on his behalf, one by his brother James in 1813 for his cannon and one relating to railways by Charles Fox in 1847. Many of his inventions had little direct influence but anticipated much later developments. His ideas were sound and some of his engines and machine tools were in use for over sixty years. He was elected a Member of the Institution of Civil Engineers in 1835.

  • 7 Whitworth, Sir Joseph

    [br]
    b. 21 December 1803 Stockport, Cheshire, England
    d. 22 January 1887 Monte Carlo, Monaco
    [br]
    English mechanical engineer and pioneer of precision measurement.
    [br]
    Joseph Whitworth received his early education in a school kept by his father, but from the age of 12 he attended a school near Leeds. At 14 he joined his uncle's mill near Ambergate, Derbyshire, to learn the business of cotton spinning. In the four years he spent there he realized that he was more interested in the machinery than in managing a cotton mill. In 1821 he obtained employment as a mechanic with Crighton \& Co., Manchester. In 1825 he moved to London and worked for Henry Maudslay and later for the Holtzapffels and Joseph Clement. After these years spent gaining experience, he returned to Manchester in 1833 and set up in a small workshop under a sign "Joseph Whitworth, Tool Maker, from London".
    The business expanded steadily and the firm made machine tools of all types and other engineering products including steam engines. From 1834 Whitworth obtained many patents in the fields of machine tools, textile and knitting machinery and road-sweeping machines. By 1851 the company was generally regarded as the leading manufacturer of machine tools in the country. Whitworth was a pioneer of precise measurement and demonstrated the fundamental mode of producing a true plane by making surface plates in sets of three. He advocated the use of the decimal system and made use of limit gauges, and he established a standard screw thread which was adopted as the national standard. In 1853 Whitworth visited America as a member of a Royal Commission and reported on American industry. At the time of the Crimean War in 1854 he was asked to provide machinery for manufacturing rifles and this led him to design an improved rifle of his own. Although tests in 1857 showed this to be much superior to all others, it was not adopted by the War Office. Whitworth's experiments with small arms led on to the construction of big guns and projectiles. To improve the quality of the steel used for these guns, he subjected the molten metal to pressure during its solidification, this fluid-compressed steel being then known as "Whitworth steel".
    In 1868 Whitworth established thirty annual scholarships for engineering students. After his death his executors permanently endowed the Whitworth Scholarships and distributed his estate of nearly half a million pounds to various educational and charitable institutions. Whitworth was elected an Associate of the Institution of Civil Engineers in 1841 and a Member in 1848 and served on its Council for many years. He was elected a Member of the Institution of Mechanical Engineers in 1847, the year of its foundation.

  • 8 Smeaton, John

    [br]
    b. 8 June 1724 Austhorpe, near Leeds, Yorkshire, England
    d. 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.

  • 9 Adamson, Daniel

    [br]
    b. 1818 Shildon, Co. Durham, England
    d. January 1890 Didsbury, Manchester, England
    [br]
    English mechanical engineer, pioneer in the use of steel for boilers, which enabled higher pressures to be introduced; pioneer in the use of triple-and quadruple-expansion mill engines.
    [br]
    Adamson was apprenticed between 1835 and 1841 to Timothy Hackworth, then Locomotive Superintendent on the Stockton \& Darlington Railway. After this he was appointed Draughtsman, then Superintendent Engineer, at that railway's locomotive works until in 1847 he became Manager of Shildon Works. In 1850 he resigned and moved to act as General Manager of Heaton Foundry, Stockport. In the following year he commenced business on his own at Newton Moor Iron Works near Manchester, where he built up his business as an iron-founder and boilermaker. By 1872 this works had become too small and he moved to a 4 acre (1.6 hectare) site at Hyde Junction, Dukinfield. There he employed 600 men making steel boilers, heavy machinery including mill engines fitted with the American Wheelock valve gear, hydraulic plant and general millwrighting. His success was based on his early recognition of the importance of using high-pressure steam and steel instead of wrought iron. In 1852 he patented his type of flanged seam for the firetubes of Lancashire boilers, which prevented these tubes cracking through expansion. In 1862 he patented the fabrication of boilers by drilling rivet holes instead of punching them and also by drilling the holes through two plates held together in their assembly positions. He had started to use steel for some boilers he made for railway locomotives in 1857, and in 1860, only four years after Bessemer's patent, he built six mill engine boilers from steel for Platt Bros, Oldham. He solved the problems of using this new material, and by his death had made c.2,800 steel boilers with pressures up to 250 psi (17.6 kg/cm2).
    He was a pioneer in the general introduction of steel and in 1863–4 was a partner in establishing the Yorkshire Iron and Steel Works at Penistone. This was the first works to depend entirely upon Bessemer steel for engineering purposes and was later sold at a large profit to Charles Cammell \& Co., Sheffield. When he started this works, he also patented improvements both to the Bessemer converters and to the engines which provided their blast. In 1870 he helped to turn Lincolnshire into an important ironmaking area by erecting the North Lincolnshire Ironworks. He was also a shareholder in ironworks in South Wales and Cumberland.
    He contributed to the development of the stationary steam engine, for as early as 1855 he built one to run with a pressure of 150 psi (10.5 kg/cm) that worked quite satisfactorily. He reheated the steam between the cylinders of compound engines and then in 1861–2 patented a triple-expansion engine, followed in 1873 by a quadruple-expansion one to further economize steam. In 1858 he developed improved machinery for testing tensile strength and compressive resistance of materials, and in the same year patents for hydraulic lifting jacks and riveting machines were obtained.
    He was a founding member of the Iron and Steel Institute and became its President in 1888 when it visited Manchester. The previous year he had been President of the Institution of Civil Engineers when he was presented with the Bessemer Gold Medal. He was a constant contributor at the meetings of these associations as well as those of the Institution of Mechanical Engineers. He did not live to see the opening of one of his final achievements, the Manchester Ship Canal. He was the one man who, by his indomitable energy and skill at public speaking, roused the enthusiasm of the people in Manchester for this project and he made it a really practical proposition in the face of strong opposition.

    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.

    d. 1872
    [br]
    [br]
    Rankine was educated at Ayr Academy and Glasgow High School, although he appears to have learned much of his basic mathematics and physics through private study. He attended Edinburgh University and then assisted his father, who was acting as Superintendent of the Edinburgh and Dalkeith Railway. This introduction to engineering practice was followed in 1838 by his appointment as a pupil to Sir John MacNeill, and for the next four years he served under MacNeill on his Irish railway projects. While still in his early twenties, Rankine presented pioneering papers on metal fatigue and other subjects to the Institution of Civil Engineers, for which he won a prize, but he appears to have resigned from the Civils in 1857 after an argument because the Institution would not transfer his Associate Membership into full Membership. From 1844 to 1848 Rankine worked on various projects for the Caledonian Railway Company, but his interests were becoming increasingly theoretical and a series of distinguished papers for learned societies established his reputation as a leading scholar in the new science of thermodynamics. He was elected Fellow of the Royal Society in 1853. At the same time, he remained intimately involved with practical questions of applied science, in shipbuilding, marine engineering and electric telegraphy, becoming associated with the influential coterie of fellow Scots such as the Thomson brothers, Napier, Elder, and Lewis Gordon. Gordon was then the head of a large and successful engineering practice, but he was also Regius Professor of Engineering at the University of Glasgow, and when he retired from the Chair to pursue his business interests, Rankine, who had become his Assistant, was appointed in his place.
    From 1855 until his premature death in 1872, Rankine built up an impressive engineering department, providing a firm theoretical basis with a series of text books that he wrote himself and most of which remained in print for many decades. Despite his quarrel with the Institution of Civil Engineers, Rankine took a keen interest in the institutional development of the engineering profession, becoming the first President of the Institution of Engineers and Shipbuilders in Scotland, which he helped to establish in 1857. Rankine campaigned vigorously for the recognition of engineering studies as a full university degree at Glasgow, and he achieved this in 1872, the year of his death. Rankine was one of the handful of mid-nineteenth century engineers who virtually created engineering as an academic discipline.

    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.

  • 16 Roberts, Richard

    [br]
    b. 22 April 1789 Carreghova, Llanymynech, Montgomeryshire, Wales
    d. 11 March 1864 London, England
    [br]
    Welsh mechanical engineer and inventor.
    [br]
    Richard Roberts was the son of a shoemaker and tollkeeper and received only an elementary education at the village school. At the age of 10 his interest in mechanics was stimulated when he was allowed by the Curate, the Revd Griffith Howell, to use his lathe and other tools. As a young man Roberts acquired a considerable local reputation for his mechanical skills, but these were exercised only in his spare time. For many years he worked in the local limestone quarries, until at the age of 20 he obtained employment as a pattern-maker in Staffordshire. In the next few years he worked as a mechanic in Liverpool, Manchester and Salford before moving in 1814 to London, where he obtained employment with Henry Maudslay. In 1816 he set up on his own account in Manchester. He soon established a reputation there for gear-cutting and other general engineering work, especially for the textile industry, and by 1821 he was employing about twelve men. He built machine tools mainly for his own use, including, in 1817, one of the first planing machines.
    One of his first inventions was a gas meter, but his first patent was obtained in 1822 for improvements in looms. His most important contribution to textile technology was his invention of the self-acting spinning mule, patented in 1825. The normal fourteen-year term of this patent was extended in 1839 by a further seven years. Between 1826 and 1828 Roberts paid several visits to Alsace, France, arranging cottonspinning machinery for a new factory at Mulhouse. By 1826 he had become a partner in the firm of Sharp Brothers, the company then becoming Sharp, Roberts \& Co. The firm continued to build textile machinery, and in the 1830s it built locomotive engines for the newly created railways and made one experimental steam-carriage for use on roads. The partnership was dissolved in 1843, the Sharps establishing a new works to continue locomotive building while Roberts retained the existing factory, known as the Globe Works, where he soon after took as partners R.G.Dobinson and Benjamin Fothergill (1802–79). This partnership was dissolved c. 1851, and Roberts continued in business on his own for a few years before moving to London as a consulting engineer.
    During the 1840s and 1850s Roberts produced many new inventions in a variety of fields, including machine tools, clocks and watches, textile machinery, pumps and ships. One of these was a machine controlled by a punched-card system similar to the Jacquard loom for punching rivet holes in plates. This was used in the construction of the Conway and Menai Straits tubular bridges. Roberts was granted twenty-six patents, many of which, before the Patent Law Amendment Act of 1852, covered more than one invention; there were still other inventions he did not patent. He made his contribution to the discussion which led up to the 1852 Act by publishing, in 1830 and 1833, pamphlets suggesting reform of the Patent Law.
    In the early 1820s Roberts helped to establish the Manchester Mechanics' Institute, and in 1823 he was elected a member of the Literary and Philosophical Society of Manchester. He frequently contributed to their proceedings and in 1861 he was made an Honorary Member. He was elected a Member of the Institution of Civil Engineers in 1838. From 1838 to 1843 he served as a councillor of the then-new Municipal Borough of Manchester. In his final years, without the assistance of business partners, Roberts suffered financial difficulties, and at the time of his death a fund for his aid was being raised.

    English mechanical engineer and inventor.
    [br]
    It was intended that Bryan Donkin should follow his father's profession of surveyor and land agent, so he spent a year or so in that occupation before he was apprenticed to John Hall, millwright of Dartford, Kent. Donkin remained with the firm after completing his apprenticeship, and when the Fourdrinier brothers in 1802 introduced from France an invention for making paper in continuous lengths they turned to John Hall for help in developing the machine: Donkin was chosen to undertake the work. In 1803 the Fourdriniers established their own works in Bermondsey, with Bryan Donkin in charge. By 1808 Donkin had acquired the works, but he continued to manufacture paper-making machines, paying a royalty to the patentees. He also undertook other engineering work including water-wheels for driving paper and other mills. He was also involved in the development of printing machinery and the preservation of food in airtight containers. Some of these improvements were patented, and he also obtained patents relating to gearing, steel pens, paper-making and railway wheels. Other inventions of Bryan Donkin that were not patented concerned revolution counters and improvements in accurate screw threads for use in graduating mathematical scales. Donkin was elected a member of the Society of Arts in 1803 and was later Chairman of the Society's Committee of Mechanics and a Vice-President of the society. He was also a member of the Royal Astronomical Society. In 1818 a group of eight young men founded the Institution of Civil Engineers; two of them were apprentices of Bryan Donkin and he encouraged their enterprise. After a change in the rules permitted the election of members over the age of 35, he himself became a member in 1821. He served on the Council and became a Vice- President, but he resigned from the Institution in 1848.

    [br]
    b. 16 February 1822 Belfast, Ireland (now Northern Ireland)
    d. 8 May 1892 Glasgow, Scotland
    [br]
    Irish civil engineer noted for his work in hydraulics and for his design of the "Vortex" turbine.
    [br]
    James Thomson was a pupil in several civil-engineering offices, but the nature of the work was beyond his physical capacity and from 1843 onwards he devoted himself to theoretical studies. Hhe first concentrated on the problems associated with the expansion of liquids when they reach their freezing point: water is one such example. He continued this work with his younger brother, Lord Kelvin (see Thomson, Sir William).
    After experimentation with a "feathered" paddle wheel as a young man, he turned his attention to water power. In 1850 he made his first patent application, "Hydraulic machinery and steam engines": this patent became his "Vortex" turbine design. He settled in Belfast, the home of the MacAdam-Fourneyron turbine, in 1851, and as a civil engineer became the Resident Engineer to the Belfast Water Commissioners in 1853. In 1857 he was appointed Professor of Civil Engineering and Surveying at Queen's College, Belfast.
    Whilst it is understood that he made his first turbine models in Belfast, he came to an arrangement with the Williamson Brothers of Kendal to make his turbine. In 1856 Williamsons produced their first turbine to Thomson's design and drawings. This was the Vortex Williamson Number 1, which produced 5 hp (3.7 kW) under a fall of 31 ft (9.4 m) on a 9 in. (23 cm) diameter supply. The rotor of this turbine ran in a horizontal plane. For several years the Williamson catalogue described their Vortex turbine as "designed by Professor James Thomson".
    Thomson continued with his study of hydraulics and water flow both at Queen's College, Belfast, and, later, at Glasgow University, where he became Professor in 1873, succeeding Macquorn Rankine, another famous engineer. At Glasgow, James Thomson studied the flow in rivers and the effects of erosion on river beds. He was also an authority on geological formations such as the development of the basalt structure of the Giant's Causeway, north of Belfast.
    James Thomson was an extremely active engineer and a very profound teacher of civil engineering. His form of water turbine had a long life before being displaced by the turbines designed in the twentieth century.

    [br]
    b. 2 August 1845 London, England
    d. 10 November 1914 London, England
    [br]
    English hydraulic engineer who developed a direct-acting hydraulic lift.
    [br]
    Ellington was educated at Denmark Hill Grammar School, London, after which he became articled to John Penn of Greenwich. He stayed there until 1868, working latterly in the drawing office after a period of erecting plant and attending trials on board ship. For some twelve months he superintended the erection of Glengall Wharf, Old Kent Road, and the machinery used therein.
    In 1869 he went into partnership with Bryan Johnson of Chester, the company being known as Johnson \& Ellington, manufacturing mining and milling machinery. Under Ellington's influence, the firm specialized in the manufacture of hydraulic machinery. In 1874 the company acquired the right to manufacture the Brotherhood three-cylinder hydraulic engine; the company became the Hydraulic Engineering Company Ltd of Chester. Ellington developed a direct-acting hydraulic lift with a special balance arrangement that was smooth-acting and economical in water. He described the lift in a paper that was read to the Institution of Mechanical Engineers (IMechE) in 1882.
    Soon after Ellington joined the Chester firm, an Act of Parliament was passed, mainly due to his efforts, for the distribution of water under high pressure for the working of passenger and goods lifts and other hydraulic machinery in large towns. In 1872 he initiated the first hydraulic mains company at Hull, thus proving the practicability of the system of a high-pressure water-mains supply. Ellington remained as engineer to the Hull company until he was appointed a director in 1875. He was general manager and engineer of the General Hydraulic Power Company, which operated in London and had subsidiaries in Liverpool (opened in 1889), Manchester (1894) and Glasgow (1895). He maintained an interest in all these companies, as general manager and engineer, until his death.
    In 1895 he read another paper, "On hydraulic power in towns", to the Institution of Mechanical Engineers. In 1911 he became President of the IMechE; his Presidential Address was on the education of young engineers. In 1913 he delivered the Thomas Hawksley Lecture on "Water as a mechanical agent". He was Chairman of the Building Committee during the extension of the Institution's headquarters. Ellington was also a Member of Council of the Institution of Civil Engineers, a member of the Société des Ingé-nieurs Civils de France and a Governor of Imperial College of Science and Technology.

    English mechanical, civil and construction engineer best remembered as the inventor of the vacuum cleaner.

    As an engineer Booth contributed to the design of engines for Royal Navy battleships, designed and supervised the erection of a number of great wheels (in Blackpool, Vienna and Paris) and later designed factories and bridges.
    In 1900 he attended a demonstration, at St Paneras Station in London, of a new form of railway carriage cleaner that was supposed to blow the dirt into a container. It was not a very successful experiment and Booth, having considered the problem carefully, decided that sucking might be better than blowing. He tried out his idea by placing a piece of damp cloth over an upholstered armchair. When he sucked air by mouth through his cloth the dirt upon it was tangible proof of his theory.
    Various attempts were being made at this time, especially in America, to find a successful cleaner of carpets and upholstery. Booth produced the first truly satisfactory machine, which he patented in 1901, and coined the term "vacuum cleaner". He formed the Vacuum Cleaner Co. (later to become Goblin BVC Ltd) and began to manufacture his machines. For some years the company provided a cleaning service to town houses, using a large and costly vacuum cleaner (the first model cost £350). Painted scarlet, it measured 54×10×42 in. (137×25×110 cm) and was powered by a petrol-driven 5 hp piston engine. It was transported through the streets on a horse-driven van and was handled by a team of operators who parked outside the house to be cleaned. With the aid of several hundred feet of flexible hose extending from the cleaner through the windows into all the rooms, the machine sucked the dirt of decades from the carpets; at the first cleaning the weight of many such carpets was reduced by 50 per cent as the dirt was sucked away.
    Many attempts were made in Europe and America to produce a smaller and less expensive machine. Booth himself designed the chief British model in 1906, the Trolley- Vac, which was wheeled around the house on a trolley. Still elaborate, expensive and heavy, this machine could, however, be operated inside a room and was powered from an electric light fitting. It consisted of a sophisticated electric motor and a belt-driven rotary vacuum pump. Various hoses and fitments made possible the cleaning of many different surfaces and the dust was trapped in a cloth filter within a small metal canister. It was a superb vacuum cleaner but cost 35 guineas and weighed a hundredweight (50 kg), so it was difficult to take upstairs.
    Various alternative machines that were cheaper and lighter were devised, but none was truly efficient until a prototype that married a small electric motor to the machine was produced in 1907 in America.
