15 Crossley, Sir Francis
SUBJECT AREA: Textiles[br]b. 26 October 1817 Halifax, Englandd. 5 January 1872 Belle Vue, Halifax, England[br]English developer of a power loom for weaving carpets.[br]Francis Crossley was the youngest of three brothers employed in their father's carpet-weaving business in Halifax and who took over the running of the company on their father's death in 1837. Francis seems to have been the one with technical ability, for it was he who saw the possibilities of weaving by power. Growth of the company was rapid through his policy of acquiring patents and then improving them, and it was soon at the forefront of the carpet-manufacturing trade. He had taken out rights on the patents of John Hill of Manchester, but his experiments with Hill's looms for weaving carpets were not successful.In the spring of 1850 Francis asked a textile inventor, George Collier of Barnsley, to develop a power loom for carpet manufacture. Collier produced a model that was a distinct advance on earlier looms, and Francis engaged him to perfect a power loom for weaving tapestry and Brussels carpets. After a great deal of money had been expended, a patent was taken out in 1850 in the name of his brother, Joseph Crossley, for a loom that could weave velvet as well as carpets and included some of the ideas of the American E.B. Bigelow. This new loom proved to be a great advance on all the earlier ones, and thus brought the Crossleys a great fortune from both sales of patent rights and the production of carpets from their mills, which were soon enlarged.According to the Dictionary of National Biography, Francis Crossley was Mayor of Halifax in 1849 and 1850, but Hogg gives this position to his elder brother John. In 1852 Francis was returned to Parliament as the Liberal member for Halifax, and in 1859 he became the member for the West Riding. Among his benefactions, in 1855 he gave to the town of Halifax a twelve-acre park that cost £41,300; a statue of him was erected there. In the same year he endowed twenty-one almshouses. In 1863 a baronetcy was conferred upon him in recognition of his commercial and public services, which he continued to perform until his death. In 1870 he gave the London Missionary Society £20,000, their largest single donation up to that time, and another £10,000 to the Congregational Pastor's Retiring Fund. He became ill when on a journey to the Holy Land in 1869, but although he made a partial recovery he grew worse again towards the end of 1871 and died early in the following year. He left £800,000 in his will.[br]Principal Honours and DistinctionsBaronet 1863.Further ReadingObituary, 1872, The Times 6 January.Dictionary of National Biography.J.Hogg (ed.), n.d., Fortunes Made in Business, London (provides an account of Crossley's career).RLH -
16 Egerton, Francis, 3rd Duke of Bridgewater
SUBJECT AREA: Ports and shipping[br]b. 21 May 1736d. 9 March 1803 London, England[br]English entrepreneur, described as the "father of British inland navigation".[br]Francis Egerton was the younger of the two surviving sons of Scroop, 1st Duke of Bridgewater, and on the death of his brother, the 2nd Duke, he succeeded to the title in 1748. Until that time he had received little or no education as his mother considered him to be of feeble intellect. His guardians, the Duke of Bedford and Lord Trentham, decided he should be given an opportunity and sent him to Eton in 1749. He remained there for three years and then went on the "grand tour" of Europe. During this period he saw the Canal du Midi, though whether this was the spark that ignited his interest in canals is hard to say. On his return to England he indulged in the social round in London and raced at Newmarket. After two unsuccessful attempts at marriage he retired to Lancashire to further his mining interests at Worsley, where the construction of a canal to Manchester was already being considered. In fact, the Act for the Bridgewater Canal had been passed at the time he left London. John Gilbert, his land agent at Worsley, encouraged the Duke to pursue the canal project, which had received parliamentary approval in March 1759. Brindley had been recommended on account of his work at Trentham, the estate of the Duke's brother-in-law, and Brindley was consulted and subsequently appointed Engineer; the canal opened on 17 July 1761. This was immediately followed by an extension project from Longford Brook to Runcorn to improve communications between Manchester and Liverpool; this was completed on 31 December 1772, after Brindley's death. The Duke also invested heavily in the Trent \& Mersey Canal, but his interests were confined to his mines and the completed canals for the rest of his life.It is said that he lacked a sense of humour and even refused to read books. He was untidy in his dress and habits yet he was devoted to the Worsley undertakings. When travelling to Worsley he would have his coach placed on a barge so that he could inspect the canal during the journey. He amassed a great fortune from his various activities, but when he died, instead of leaving his beloved canal to the beneficiaries under his will, he created a trust to ensure that the canal would endure; the trust did not expire until 1903. The Duke is commemorated by a large Corinthian pillar, which is now in the care of the National Trust, in the grounds of his mansion at Ashridge, Hertfordshire.[br]Further ReadingH.Malet, 1961, The Canal Duke, Dawlish: David \& Charles.JHBBiographical history of technology > Egerton, Francis, 3rd Duke of Bridgewater

17 Elgar, Francis
SUBJECT AREA: Ports and shipping[br]b. April 1845 Portsmouth, Englandd. 16 January 1909 Monte Carlo, Monaco[br]English naval architect and shipbuilder.[br]Elgar enjoyed a fascinating professional life, during which he achieved distinction in the military, merchant, academic and political aspects of his profession. At the age of 14 he was apprenticed as a shipwright to the Royal Dockyard at Portsmouth but when he was in his late teens he was selected as one of the Admiralty students to further his education at the Royal School of Naval Architecture at South Kensington, London. On completion of the course he was appointed to Birkenhead, where the ill-fated HMS Captain was being built, and then to Portsmouth Dockyard. In 1870 the Captain was lost at sea and Francis Elgar was called on to prepare much of the evidence for the Court Martial. This began his life-long interest in ship stability and in ways of presenting this information in an easily understood form to ship operators.In 1883 he accepted the John Elder Chair of Naval Architecture at Glasgow University, an appointment which formalized the already well-established teaching of this branch of engineering at Glasgow. However, after only three years he returned to public service in the newly created post of Director of Royal Dockyards, a post that he held for a mere six years but which brought about great advances in the speed of warship construction, with associated reductions in cost. In 1892 he was made Naval Architect and Director of the Fairfield Shipbuilding Company in Glasgow, remaining there until he retired in 1907. The following year he accepted the post of Chairman of the Birkenhead shipyard of Cammell Laird \& Co.; this was a recent amalgamation of two companies, and he retained this position until his death. Throughout his life, Elgar acted on many consultative bodies and committees, including the 1884 Ship Load Line Enquiry. His work enabled him to keep abreast of all current thinking in ship design and construction.[br]Principal Honours and DistinctionsFRS. FRSE. Chevalier de la Légion d'honneur.BibliographyElgar produced some remarkable papers, which were published by the Institutions of Naval Architects, Civil Engineers and Engineers and Shipbuilders in Scotland as well as by the Royal Society. He published several books on shipbuilding.FMW -

19 Pratt, Francis Ashbury
[br]b. 15 February 1827 Woodstock, Vermont, USAd. 10 February 1902 Hartford, Connecticut, USA[br]American mechanical engineer and machine-tool manufacturer.[br]Francis A.Pratt served an apprenticeship as a machinist with Warren Aldrich, and on completing it in 1848 he entered the Gloucester Machine Works as a journeyman machinist. From 1852 to 1854 he worked at the Colt Armory in Hartford, Connecticut, where he met his future partner, Amos Whitney. He then became Superintendent of the Phoenix Iron Works, also at Hartford and run by George S.Lincoln \& Company. While there he designed the well-known "Lincoln" miller, which was first produced in 1855. This was a development of the milling machine built by Robbins \& Lawrence and designed by F.W. Howe, and incorporated a screw drive for the table instead of the rack and pinion used in the earlier machine.Whitney also moved to the Phoenix Iron Works, and in 1860 the two men started in a small way doing machine work on their own account. In 1862 they took a third partner, Monroe Stannard, and enlarged their workshop. The business continued to expand, but Pratt and Whitney remained at the Phoenix Iron Works until 1864 and in the following year they built their first new factory. The Pratt \& Whitney Company was incorporated in 1869 with a capital of $350,000, F.A.Pratt being elected President. The firm specialized in making machine tools and tools particularly for the armament industry. In the 1870s Pratt made no less than ten trips to Europe gaining orders for equipping armouries in many different countries. Pratt \& Whitney was one of the leading firms developing the system of interchangeable manufacture which led to the need to establish national standards of measurement. The Rogers-Bond Comparator, developed with the backing of Pratt \& Whitney, played an important part in the establishment of these standards, which formed the basis of the gauges of many various types made by the firm. Pratt remained President of the company until 1898, after which he served as their Consulting Engineer for a short time before retiring from professional life. He was granted a number of patents relating to machine tools. He was a founder member of the American Society of Mechanical Engineers in 1880 and was elected a vice-president in 1881. He was an alderman of the city of Hartford.[br]Principal Honours and DistinctionsVice-President, American Society of Mechanical Engineers 1881.Further ReadingJ.W.Roe, 1916, English and American Tool Builders, New Haven; reprinted 1926, New York, and 1987, Bradley, 111.

20 Rogallo, Francis Melvin
SUBJECT AREA: Aerospace[br]b. 1912 USA[br]American engineer who patented a flexible-winged hand-glider in 1948.[br]After the hang-gliders of pioneers such as Lilienthal, Pilcher and Chanute in the 1890s, this form of flying virtually disappeared for seventy years. It was reintroduced in the late 1960s based on Francis Rogallo's flexible wing, patented in the United States in 1948. Rogallo's wing was very basic: it consisted of a fabric delta wing with a solid boom along each leading edge and one along the centre line. Between these booms, the fabric was free to billow out into two partial cones. Variations of the Rogallo flexible wing were investigated in the 1960s by Ryans as a means of recovering space vehicles (e.g. Saturn booster), and by North American for the recovery of Gemini spacecraft. In 1963 a version with a 155 kW (210 hp) engine was tested by the US services as a potential lightweight transport vehicle. None of these made a great impact and the Rogallo wing became popular as a hang-glider c. 1970. The pilot was suspended in a harness below a lightweight Rogallo wing. A framework attached to the wing structure allowed the pilot to move his or her body in any direction relative to the wing. Thus, if they wished to dive, they would move their weight forward, which made the glider nose-heavy. This was a great improvement over the earlier hang-gliders, in which the upper part of the pilot's body was held in a fixed position and control was achieved by swinging the legs. Rogallo-wing hang-gliders became very popular as they were relatively cheap and easy to transport. Once the sport developed, powered "microlights" made their appearance and a new branch of popular flying was established.[br]Further ReadingAnn Welsh, 1977, "Hang glider development", Aerospace (Royal Aeronautical Society) (August/September).JDSBiographical history of technology > Rogallo, Francis Melvin
