  • 5 Harrison, John

    [br]
    b. 24 March 1693 Foulby, Yorkshire, England
    d. 24 March 1776 London, England
    [br]
    English horologist who constructed the first timekeeper of sufficient accuracy to determine longitude at sea and invented the gridiron pendulum for temperature compensation.
    [br]
    John Harrison was the son of a carpenter and was brought up to that trade. He was largely self-taught and learned mechanics from a copy of Nicholas Saunderson's lectures that had been lent to him. With the assistance of his younger brother, James, he built a series of unconventional clocks, mainly of wood. He was always concerned to reduce friction, without using oil, and this influenced the design of his "grasshopper" escapement. He also invented the "gridiron" compensation pendulum, which depended on the differential expansion of brass and steel. The excellent performance of his regulator clocks, which incorporated these devices, convinced him that they could also be used in a sea dock to compete for the longitude prize. In 1714 the Government had offered a prize of £20,000 for a method of determining longitude at sea to within half a degree after a voyage to the West Indies. In theory the longitude could be found by carrying an accurate timepiece that would indicate the time at a known longitude, but the requirements of the Act were very exacting. The timepiece would have to have a cumulative error of no more than two minutes after a voyage lasting six weeks.
    In 1730 Harrison went to London with his proposal for a sea clock, supported by examples of his grasshopper escapement and his gridiron pendulum. His proposal received sufficient encouragement and financial support, from George Graham and others, to enable him to return to Barrow and construct his first sea clock, which he completed five years later. This was a large and complicated machine that was made out of brass but retained the wooden wheelwork and the grasshopper escapement of the regulator clocks. The two balances were interlinked to counteract the rolling of the vessel and were controlled by helical springs operating in tension. It was the first timepiece with a balance to have temperature compensation. The effect of temperature change on the timekeeping of a balance is more pronounced than it is for a pendulum, as two effects are involved: the change in the size of the balance; and the change in the elasticity of the balance spring. Harrison compensated for both effects by using a gridiron arrangement to alter the tension in the springs. This timekeeper performed creditably when it was tested on a voyage to Lisbon, and the Board of Longitude agreed to finance improved models. Harrison's second timekeeper dispensed with the use of wood and had the added refinement of a remontoire, but even before it was tested he had embarked on a third machine. The balance of this machine was controlled by a spiral spring whose effective length was altered by a bimetallic strip to compensate for changes in temperature. In 1753 Harrison commissioned a London watchmaker, John Jefferys, to make a watch for his own personal use, with a similar form of temperature compensation and a modified verge escapement that was intended to compensate for the lack of isochronism of the balance spring. The time-keeping of this watch was surprisingly good and Harrison proceeded to build a larger and more sophisticated version, with a remontoire. This timekeeper was completed in 1759 and its performance was so remarkable that Harrison decided to enter it for the longitude prize in place of his third machine. It was tested on two voyages to the West Indies and on both occasions it met the requirements of the Act, but the Board of Longitude withheld half the prize money until they had proof that the timekeeper could be duplicated. Copies were made by Harrison and by Larcum Kendall, but the Board still continued to prevaricate and Harrison received the full amount of the prize in 1773 only after George III had intervened on his behalf.
    Although Harrison had shown that it was possible to construct a timepiece of sufficient accuracy to determine longitude at sea, his solution was too complex and costly to be produced in quantity. It had, for example, taken Larcum Kendall two years to produce his copy of Harrison's fourth timekeeper, but Harrison had overcome the psychological barrier and opened the door for others to produce chronometers in quantity at an affordable price. This was achieved before the end of the century by Arnold and Earnshaw, but they used an entirely different design that owed more to Le Roy than it did to Harrison and which only retained Harrison's maintaining power.

  • 6 Nervi, Pier Luigi

    [br]
    b. 21 June 1891 Sondrio, Italy
    d. 9 January 1979 (?), Italy
    [br]
    Italian engineer who played a vital role in the use and adaptation of reinforced concrete as a structural material from the 1930s to the 1970s.
    [br]
    Nervi early established a reputation in the use of reinforced concrete with his stadium in Florence (1930–2). This elegant concrete structure combines graceful curves with functional solidity and is capable of seating some 35,000 spectators. The stadium was followed by the aircraft hangars built for the Italian Air Force at Orvieto and Ortebello, in which he spanned the vast roofs of the hangars with thin-shelled vaults supported by precast concrete beams and steel-reinforced ribs. The structural strength and subtle curves of these ribbed roofs set the pattern for Nervi's techniques, which he subsequently varied and elaborated on to solve problems that arose in further commissions.
    Immediately after the Second World War Italy was short of supplies of steel for structural purposes so, in contrast to the USA, Britain and Germany, did not for some years construct any quantity of steel-framed rectangular buildinngs used for offices, housing or industrial use. It was Nervi who led the way to a ferroconcrete approach, using a new type of structure based on these materials in the form of a fine steel mesh sprayed with cement mortar and used to roof all kinds of structures. It was a method that resulted in expressionist curves instead of rectangular blocks, and the first of his great exhibition halls at Turin (1949), with a vault span of 240 ft (73 m), was an early example of this technique. Nervi continued to create original and beautiful ferroconcrete structures of infinite variety: for example, the hall at the Lido di Roma, Ostia; the terme at Chianciano; and the three buildings that he designed for the Rome Olympics in 1960. The Palazzetto dello Sport is probably the most famous of these, for which he co-operated with the architect Annibale Vitellozzi to construct a small sports palace seating 5,000 spectators under a concrete "big top" of 194 ft (59 m) diameter, its enclosing walls supported by thirtysix guy ropes of concrete; inside, the elegant roof displays a floral quality. In 1960 Nervi returned to Turin to build his imaginative Palace of Labour for the centenary celebrations of Garibaldi and Victor Emmanuel in the city. This vast hall, like the Crystal Palace in England a century earlier (see Paxton), had to be built quickly and be suitable for later adaptation. It was therefore constructed partly in steel, and the metal supporting columns rose to palm-leaf capitals reminiscent of those in ancient Nile palaces.
    Nervi's aim was always to create functional buildings that simultaneously act by their aesthetic qualities as an effective educational influence. Functionalism for Nervi never became "brutalism". In consequence, his work is admired by the lay public as well as by architects. He collaborated with many of the outstanding architects of the day: with Gio Ponti on the Pirelli Building in Milan (1955–9); with Zehrfuss and Breuer on the Y-plan UNESCO Building in Paris (1953–7); and with Marcello Piacentini on the 16,000-seat Palazzo dello Sport in Rome. Nervi found time to write a number of books on building construction and design, lectured in the Universities of Rio de Janiero and Buenos Aires, and was for many years Professor of Technology and Technique of Construction in the Faculty of Architecture at the University of Rome. He continued to design new structures until well into the 1970s.

    d. 2 May 1871 Manchester, England
    [br]
    American inventor of a popular type of roving frame for cotton manufacture.
    [br]
    As a youth, Dyer constructed an unsinkable life-boat but did not immediately pursue his mechanical bent, for at 16 he entered the counting-house of a French refugee named Nancrède and succeeded to part of the business. He first went to England in 1801 and finally settled in 1811 when he married Ellen Jones (d. 1842) of Gower Street, London. Dyer was already linked with American inventors and brought to England Perkins's plan for steel engraving in 1809, shearing and nail-making machines in 1811, and also received plans and specifications for Fulton's steamboats. He seems to have acted as a sort of British patent agent for American inventors, and in 1811 took out a patent for carding engines and a card clothing machine. In 1813 there was a patent for spinning long-fibred substances such as hemp, flax or grasses, and in 1825 there was a further patent for card making machinery. Joshua Field, on his tour through Britain in 1821, saw a wire drawing machine and a leather splitting machine at Dyer's works as well as the card-making machines. At first Dyer lived in Camden Town, London, but he had a card clothing business in Birmingham. He moved to Manchester c.1816, where he developed an extensive engineering works under the name "Joseph C.Dyer, patent card manufacturers, 8 Stanley Street, Dale Street". In 1832 he founded another works at Gamaches, Somme, France, but this enterprise was closed in 1848 with heavy losses through the mismanagement of an agent. In 1825 Dyer improved on Danforth's roving frame and started to manufacture it. While it was still a comparatively crude machine when com-pared with later versions, it had the merit of turning out a large quantity of work and was very popular, realizing a large sum of money. He patented the machine that year and must have continued his interest in these machines as further patents followed in 1830 and 1835. In 1821 Dyer had been involved in the foundation of the Manchester Guardian (now The Guardian) and he was linked with the construction of the Liverpool \& Manchester Railway. He was not so successful with the ill-fated Bank of Manchester, of which he was a director and in which he lost £98,000. Dyer played an active role in the community and presented many papers to the Manchester Literary and Philosophical Society. He helped to establish the Royal Institution in London and the Mechanics Institution in Manchester. In 1830 he was a member of the delegation to Paris to take contributions from the town of Manchester for the relief of those wounded in the July revolution and to congratulate Louis-Philippe on his accession. He called for the reform of Parliament and helped to form the Anti-Corn Law League. He hated slavery and wrote several articles on the subject, both prior to and during the American Civil War.

    fl. c.1808–25 London (?), England
    d. after 1825 France (?)
    [br]
    English co-developer of Woolf s compound steam engine.
    [br]
    When Arthur Woolf left the Griffin Brewery, London, in October 1808, he formed a partnership with Humphrey Edwards, described as a millwright at Mill Street, Lambeth, where they started an engine works to build Woolf's type of compound engine. A number of small engines were constructed and other ordinary engines modified with the addition of a high-pressure cylinder. Improvements were made in each succeeding engine, and by 1811 a standard form had been evolved. During this experimental period, engines were made with cylinders side by side as well as the more usual layout with one behind the other. The valve gear and other details were also improved. Steam pressure may have been around 40 psi (2.8 kg/cm2). In an advertisement of February 1811, the partners claimed that their engines had been brought to such a state of perfection that they consumed only half the quantity of coal required for engines on the plan of Messrs Boulton \& Watt. Woolf visited Cornwall, where he realized that more potential for his engines lay there than in London; in May 1811 the partnership was dissolved, with Woolf returning to his home county. Edwards struggled on alone in London for a while, but when he saw a more promising future for the engine in France he moved to Paris. On 25 May 1815 he obtained a French patent, a Brevet d'importation, for ten years. A report in 1817 shows that during the previous two years he had imported into France fifteen engines of different sizes which were at work in eight places in various parts of the country. He licensed a mining company in the north of France to make twenty-five engines for winding coal. In France there was always much more interest in rotative engines than pumping ones. Edwards may have formed a partnership with Goupil \& Cie, Dampierre, to build engines, but this is uncertain. He became a member of the firm Scipion, Perrier, Edwards \& Chappert, which took over the Chaillot Foundry of the Perrier Frères in Paris, and it seems that Edwards continued to build steam engines there for the rest of his life. In 1824 it was claimed that he had made about 100 engines in England and another 200 in France, but this is probably an exaggeration.
    The Woolf engine acquired its popularity in France because its compound design was more economical than the single-cylinder type. To enable it to be operated safely, Edwards first modified Woolf s cast-iron boiler in 1815 by placing two small drums over the fire, and then in 1825 replaced the cast iron with wrought iron. The modified boiler was eventually brought back to England in the 1850s as the "French" or "elephant" boiler.
