102 the milk of human kindness
сострадание, доброта, сердечность [шекспировское выражение; см. цитату]Lady Macbeth: "...yet do I fear thy nature; It is too full o' the milk of human kindness To catch the nearest way: thou wouldst be great; Art not without ambition, but without The illness should attend it. What thou wouldst highly. That wouldst thou holily... " (W. Shakespeare, ‘Macbeth’, act I, sc. 5) — Леди Макбет: "...но я боюсь, что нрав твой чрезмерно полон благостного млека, чтоб взять кратчайший путь. Ты ждешь величья. Ты не лишен тщеславья, но лишен Услуг порочности. Ты жаждешь сильно, Но жаждешь свято." (перевод М. Лозинского)
Sellers said privately that Rossmore was the most extraordinary character he had ever met - a man just made out of the condensed milk of human kindness... (M. Twain, ‘The American Claimant’, ch. XXV) — Селлерс сказал в частной беседе, что Россмор был самым необыкновенным человеком, которого он когда-либо встречал, человеком, являвшимся воплощением доброты и сердечности...
Besides, a man with the milk of human kindness in him can scarcely abstain from doing a good-natured action, and one cannot be good-natured all around. (G. Eliot, ‘The Mill on the Floss’, book I, ch. III) — К тому же человеку добросердечному трудно устоять, если представится возможность проявить доброту и участие, но не может же он жалеть весь свет.
The milk of human kindness was softening the iron resolution of this man of steel. (J. Conroy, ‘The Disinherited’, part II, ch. V) — Млеко человеческой доброты смягчило непреклонную решимость этого человека.

106 Arnold, Aza
SUBJECT AREA: Textiles[br]b. 4 October 1788 Smithfield, Pawtucket, Rhode Island, USAd. 1865 Washington, DC, USA[br]American textile machinist who applied the differential motion to roving frames, solving the problem of winding on the delicate cotton rovings.[br]He was the son of Benjamin and Isabel Arnold, but his mother died when he was 2 years old and after his father's second marriage he was largely left to look after himself. After attending the village school he learnt the trade of a carpenter, and following this he became a machinist. He entered the employment of Samuel Slater, but left after a few years to engage in the unsuccessful manufacture of woollen blankets. He became involved in an engineering shop, where he devised a machine for taking wool off a carding machine and making it into endless slivers or rovings for spinning. He then became associated with a cotton-spinning mill, which led to his most important invention. The carded cotton sliver had to be reduced in thickness before it could be spun on the final machines such as the mule or the waterframe. The roving, as the mass of cotton fibres was called at this stage, was thin and very delicate because it could not be twisted to give strength, as this would not allow it to be drawn out again during the next stage. In order to wind the roving on to bobbins, the speed of the bobbin had to be just right but the diameter of the bobbin increased as it was filled. Obtaining the correct reduction in speed as the circumference increased was partially solved by the use of double-coned pulleys, but the driving belt was liable to slip owing to the power that had to be transmitted.The final solution to the problem came with the introduction of the differential drive with bevel gears or a sun-and-planet motion. Arnold had invented this compound motion in 1818 but did not think of applying it to the roving frame until 1820. It combined the direct-gearing drive from the main shaft of the machine with that from the cone-drum drive so that the latter only provided the difference between flyer and bobbin speeds, which meant that most of the transmission power was taken away from the belt. The patent for this invention was issued to Arnold on 23 January 1823 and was soon copied in Britain by Henry Houldsworth, although J.Green of Mansfield may have originated it independendy in the same year. Arnold's patent was widely infringed in America and he sued the Proprietors of the Locks and Canals, machine makers for the Lowell manufacturers, for $30,000, eventually receiving $3,500 compensation. Arnold had his own machine shop but he gave it up in 1838 and moved the Philadelphia, where he operated the Mulhausen Print Works. Around 1850 he went to Washington, DC, and became a patent attorney, remaining as such until his death. On 24 June 1856 he was granted patent for a self-setting and self-raking saw for sawing machines.[br]Bibliography28 June 1856, US patent no. 15,163 (self-setting and self-raking saw for sawing machines).Further ReadingDictionary of American Biography, Vol. 1.W.English, 1969, The Textile Industry, London (a description of the principles of the differential gear applied to the roving frame).D.J.Jeremy, 1981, Transatlantic Industrial Revolution.

107 Bell, Thomas
SUBJECT AREA: Paper and printing[br]fl. 1770–1785 Scotland[br]Scottish inventor of a calico printing machine with the design engraved on rollers.[br]In November 1770, John Mackenzie, owner of a bleaching mill, took his millwright Thomas Bell to Glasgow to consult with James Watt about problems they were having with the calico printing machine invented by Bell some years previously. Bell rolled sheets of copper one eighth of an inch (3 mm) thick into cyliders, and filled them with cement which was held in place by cast iron ends. After being turned true and polished, the cylinders were engraved; they cost about £10 each. The printing machines were driven by a water-wheel, but Bell and Mackenzie appeared to have had problems with the doctor blades which scraped off excess colour, and this may have been why they visited Watt.They had, presumably, solved the technical problems when Bell took out a patent in 1783 which describes him as "the Elder", but there are no further details about the man himself. The machine is described as having six printing rollers arranged around the top of the circumference of a large central bowl. In later machines, the printing rollers were placed all round a smaller cylinder. All of the printing rollers, each printing a different colour, were driven by gearing to keep them in register. The patent includes steel doctor blades which would have scraped excess colour off the printing rollers. Another patent, taken out in 1784, shows a smaller three-colour machine. The printing rollers had an iron core covered with copper, which could be taken off at pleasure so that fresh patterns could be cut as desired. Bell's machine was used at Masney, near Preston, England, by Messrs Livesey, Hargreaves, Hall \& Co in 1786. Although copper cylinders were difficult to make and engrave, and the soldered seams often burst, these machines were able to increase the output of the cheaper types of printed cloth.[br]Bibliography1783, patent no. 1,378 (calico printing machine with engraved copper rollers). 1784, patent no. 1,443 (three-colour calico printing machine).Further ReadingW.E.A.Axon, 1886, Annals of Manchester, Manchester (provides an account of the invention).R.L.Hills, 1970, Power in the Industrial Revolution, Manchester (provides a brief description of the development of calico printing).RLH -
108 Cubitt, William
[br]b. 1785 Dilham, Norfolk, Englandd. 13 October 1861 Clapham Common, Surrey, England[br]English civil engineer and contractor.[br]The son of a miller, he received a rudimentary education in the village school. At an early age he was helping his father in the mill, and in 1800 he was apprenticed to a cabinet maker. After four years he returned to work with his father, but, preferring to leave the parental home, he not long afterwards joined a firm of agricultural-machinery makers in Swanton in Norfolk. There he acquired a reputation for making accurate patterns for the iron caster and demonstrated a talent for mechanical invention, patenting a self-regulating windmill sail in 1807. He then set up on his own as a millwright, but he found he could better himself by joining the engineering works of Ransomes of Ipswich in 1812. He was soon appointed their Chief Engineer, and after nine years he became a partner in the firm until he moved to London in 1826. Around 1818 he invented the treadmill, with the aim of putting prisoners to useful work in grinding corn and other applications. It was rapidly adopted by the principal prisons, more as a means of punishment than an instrument of useful work.From 1814 Cubitt had been gaining experience in civil engineering, and upon his removal to London his career in this field began to take off. He was engaged on many canal-building projects, including the Oxford and Liverpool Junction canals. He accomplished some notable dock works, such as the Bute docks at Cardiff, the Middlesborough docks and the coal drops on the river Tees. He improved navigation on the river Severn and compiled valuable reports on a number of other leading rivers.The railway construction boom of the 1840s provided him with fresh opportunities. He engineered the South Eastern Railway (SER) with its daringly constructed line below the cliffs between Folkestone and Dover; the railway was completed in 1843, using massive charges of explosive to blast a way through the cliffs. Cubitt was Consulting Engineer to the Great Northern Railway and tried, with less than his usual success, to get the atmospheric system to work on the Croydon Railway.When the SER began a steamer service between Folkestone and Boulogne, Cubitt was engaged to improve the port facilities there and went on to act as Consulting Engineer to the Boulogne and Amiens Railway. Other commissions on the European continent included surveying the line between Paris and Lyons, advising the Hanoverian government on the harbour and docks at Hamburg and directing the water-supply works for Berlin.Cubitt was actively involved in the erection of the Crystal Palace for the Great Exhibition of 1851; in recognition of this work Queen Victoria knighted him at Windsor Castle on 23 December 1851.Cubitt's son Joseph (1811–72) was also a notable civil engineer, with many railway and harbour works to his credit.[br]Principal Honours and DistinctionsKnighted 1851.

109 Edwards, Humphrey
SUBJECT AREA: Steam and internal combustion engines[br]fl. c.1808–25 London (?), Englandd. 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.[br]Further ReadingMost details about Edwards are to be found in the biographies of his partner, Arthur Woolf. For example, see T.R.Harris, 1966, Arthur Woolf, 1766–1837, The Cornish Engineer, Truro: D.Bradford Barton; Rhys Jenkins, 1932–3, "A Cornish Engineer, Arthur Woolf, 1766–1837", Transactions of the Newcomen Society 13.

110 Hargreaves, James
SUBJECT AREA: Textiles[br]b. c.1720–1 Oswaldtwistle, near Blackburn, Englandd. April 1778 Nottingham, England[br]English inventor of the first successful machine to spin more than a couple of yarns of cotton or wool at once.[br]James Hargreaves was first a carpenter and then a hand-loom weaver at Stanhill, Blackburn, probably making Blackburn Checks or Greys from linen warps and cotton weft. An invention ascribed to him doubled production in the preparatory carding process before spinning. Two or three cards were nailed to the same stock and the upper one was suspended from the ceiling by a cord and counterweight. Around 1762 Robert Peel (1750–1830) sought his assistance in constructing a carding engine with cylinders that may have originated with Daniel Bourn, but this was not successful. In 1764, inspired by seeing a spinning wheel that continued to revolve after it had been knocked over accidentally, Hargreaves invented his spinning jenny. The first jennies had horizontal wheels and could spin eight threads at once. To spin on this machine required a great deal of skill. A length of roving was passed through the clamp or clove. The left hand was used to close this and draw the roving away from the spindles which were rotated by the spinner turning the horizontal wheel with the right hand. The spindles twisted the fibres as they were being drawn out. At the end of the draw, the spindles continued to be rotated until sufficient twist had been put into the fibres to make the finished yarn. This was backed off from the tips of the spindles by reversing them and then, with the spindles turning in the spinning direction once more, the yarn was wound on by the right hand rotating the spindles, the left hand pushing the clove back towards them and one foot operating a pedal which guided the yarn onto the spindles by a faller wire. A piecer was needed to rejoin the yarns when they broke. At first Hargreaves's jenny was worked only by his family, but then he sold two or three of them, possibly to Peel. In 1768, local opposition and a riot in which his house was gutted forced him to flee to Nottingham. He entered into partnership there with Thomas James and established a cotton mill. In 1770 he followed Arkwright's example and sought to patent his machine and brought an action for infringement against some Lancashire manufacturers, who offered £3,000 in settlement. Hargreaves held out for £4,000, but he was unable to enforce his patent because he had sold jennies before leaving Lancashire. Arkwright's "water twist" was more suitable for the Nottingham hosiery industry trade than jenny yarn and in 1777 Hargreaves replaced his own machines with Arkwright's. When he died the following year, he is said to have left property valued at £7,000 and his widow received £400 for her share in the business. Once the jenny had been made public, it was quickly improved by other inventors and the number of spindles per machine increased. In 1784, there were reputed to be 20,000 jennies of 80 spindles each at work. The jenny greatly eased the shortage of cotton weft for weavers.[br]Bibliography1770, British patent no. 962 (spinning jenny).Further ReadingC.Aspin and S.D.Chapman, 1964, James Hargreaves and the Spinning Jenny, Helmshore Local History Society (the fullest account of Hargreaves's life and inventions).For descriptions of his invention, see W.English, 1969, The Textile Industry, London; R.L.

111 Kay (of Warrington), John
SUBJECT AREA: Textiles[br]fl. c.1770 England[br]English clockmaker who helped Richard Arkwright to construct his spinning machine.[br]John Kay was a clockmaker of Warrington. He moved to Leigh, where he helped Thomas Highs to construct his spinning machine, but lack of success made them abandon their attempts. Kay first met Richard Arkwright in March 1767 and six months later was persuaded by Arkwright to make one or more models of the roller spinning machine he had built under Highs's supervision. Kay went with Arkwright to Preston, where they continued working on the machine. Kay also went with Arkwright when he moved to Nottingham. It was around this time that he entered into an agreement with Arkwright to serve him for twenty-one years and was bound not to disclose any details of the machines. Presumably Kay helped to set up the first spinning machines at Arkwright's Nottingham mill as well as at Cromford. Despite their agreement, he seems to have left after about five years and may have disclosed the secret of Arkwright's crank and comb on the carding engine to others. Kay was later to give evidence against Arkwright during the trial of his patent in 1785.[br]Further ReadingR.S.Fitton, 1989, The Arkwrights, Spinners of Fortune, Manchester (the most detailed account of Kay's connections with Arkwright and his evidence during the later patent trials).A.P.Wadsworth and J. de L.Mann, 1931, The Cotton Trade and Industrial Lancashire, Manchester (mentions Kay's association with Arkwright).RLHBiographical history of technology > Kay (of Warrington), John

112 Knight, Margaret E.
[br]b. 1838 Maine, USAd. 1914 USA[br]American inventor.[br]Little is known of Knight's childhood, except that she was probably educated to high school level. She made her first invention at the age of 12, after seeing a woman cotton-mill worker injured when a dislodged shuttle fell on her. Knight set herself to design a mechanism that would shut down the machine if the thread broke and caused a shuttle to fly out. The device was widely used by cotton and woollen mills. Between that and her first patent in 1870, little is known of her activities; but she then embarked on a career of invention, achieving over 90 of them, earning herself the title "the female Edison ". Perhaps her most notable invention was a machine for making paper bags with square or satchel bottoms, which proved to be of great benefit to shoppers until the advent of the plastic bag. It won her little financial reward, but a decoration from Queen Victoria. Her other two main inventions related to the manufacture of shoes and, around 1902, to a rotary automobile engine. She worked for various companies, assigning to them her patent rights, so that at her death her estate was valued at less than $300.[br]Further ReadingA.Stanley, 1993, Mothers and Daughters of Invention, Meruchen, NJ: Scarecrow Press.LRD -
113 Leonardo da Vinci
[br]b. 15 April 1452 Vinci, near Florence, Italy,d. 2 May 1519 St Cloux, near Amboise, France.[br]Italian scientist, engineer, inventor and artist.[br]Leonardo was the illegitimate son of a Florentine lawyer. His first sixteen years were spent with the lawyer's family in the rural surroundings of Vinci, which aroused in him a lifelong love of nature and an insatiable curiosity in it. He received little formal education but extended his knowledge through private reading. That gave him only a smattering of Latin, a deficiency that was to be a hindrance throughout his active life. At sixteen he was apprenticed in the studio of Andrea del Verrochio in Florence, where he received a training not only in art but in a wide variety of crafts and technical arts.In 1482 Leonardo went to Milan, where he sought and obtained employment with Ludovico Sforza, later Duke of Milan, partly to sculpt a massive equestrian statue of Ludovico but the work never progressed beyond the full-scale model stage. He did, however, complete the painting which became known as the Virgin of the Rocks and in 1497 his greatest artistic achievement, The Last Supper, commissioned jointly by Ludovico and the friars of Santa Maria della Grazie and painted on the wall of the monastery's refectory. Leonardo was responsible for the court pageants and also devised a system of irrigation to supply water to the plains of Lombardy. In 1499 the French army entered Milan and deposed Leonardo's employer. Leonardo departed and, after a brief visit to Mantua, returned to Florence, where for a time he was employed as architect and engineer to Cesare Borgia, Duke of Romagna. Around 1504 he completed another celebrated work, the Mona Lisa.In 1506 Leonardo began his second sojourn in Milan, this time in the service of King Louis XII of France, who appointed him "painter and engineer". In 1513 Leonardo left for Rome in the company of his pupil Francesco Melzi, but his time there was unproductive and he found himself out of touch with the younger artists active there, Michelangelo above all. In 1516 he accepted with relief an invitation from King François I of France to reside at the small château of St Cloux in the royal domain of Amboise. With the pension granted by François, Leonardo lived out his remaining years in tranquility at St Cloux.Leonardo's career can hardly be regarded as a success or worthy of such a towering genius. For centuries he was known only for the handful of artistic works that he managed to complete and have survived more or less intact. His main activity remained hidden until the nineteenth and twentieth centuries, during which the contents of his notebooks were gradually revealed. It became evident that Leonardo was one of the greatest scientific investigators and inventors in the history of civilization. Throughout his working life he extended a searching curiosity over an extraordinarily wide range of subjects. The notes show careful investigation of questions of mechanical and civil engineering, such as power transmission by means of pulleys and also a form of chain belting. The notebooks record many devices, such as machines for grinding and polishing lenses, a lathe operated by treadle-crank, a rolling mill with conical rollers and a spinning machine with pinion and yard divider. Leonardo made an exhaustive study of the flight of birds, with a view to designing a flying machine, which obsessed him for many years.Leonardo recorded his observations and conclusions, together with many ingenious inventions, on thousands of pages of manuscript notes, sketches and drawings. There are occasional indications that he had in mind the publication of portions of the notes in a coherent form, but he never diverted his energy into putting them in order; instead, he went on making notes. As a result, Leonardo's impact on the development of science and technology was virtually nil. Even if his notebooks had been copied and circulated, there were daunting impediments to their understanding. Leonardo was left-handed and wrote in mirror-writing: that is, in reverse from right to left. He also used his own abbreviations and no punctuation.At his death Leonardo bequeathed his entire output of notes to his friend and companion Francesco Melzi, who kept them safe until his own death in 1570. Melzi left the collection in turn to his son Orazio, whose lack of interest in the arts and sciences resulted in a sad period of dispersal which endangered their survival, but in 1636 the bulk of them, in thirteen volumes, were assembled and donated to the Ambrosian Library in Milan. These include a large volume of notes and drawings compiled from the various portions of the notebooks and is now known as the Codex Atlanticus. There they stayed, forgotten and ignored, until 1796, when Napoleon's marauding army overran Italy and art and literary works, including the thirteen volumes of Leonardo's notebooks, were pillaged and taken to Paris. After the war in 1815, the French government agreed to return them but only the Codex Atlanticus found its way back to Milan; the rest remained in Paris. The appendix to one notebook, dealing with the flight of birds, was later regarded as of sufficient importance to stand on its own. Four small collections reached Britain at various times during the seventeenth and eighteenth centuries; of these, the volume in the Royal Collection at Windsor Castle is notable for its magnificent series of anatomical drawings. Other collections include the Codex Leicester and Codex Arundel in the British Museum in London, and the Madrid Codices in Spain.Towards the end of the nineteenth century, Leonardo's true stature as scientist, engineer and inventor began to emerge, particularly with the publication of transcriptions and translations of his notebooks. The volumes in Paris appeared in 1881–97 and the Codex Atlanticus was published in Milan between 1894 and 1904.[br]Principal Honours and Distinctions"Premier peintre, architecte et mécanicien du Roi" to King François I of France, 1516.Further ReadingE.MacCurdy, 1939, The Notebooks of Leonardo da Vinci, 2 vols, London; 2nd edn, 1956, London (the most extensive selection of the notes, with an English translation).G.Vasari (trans.

114 Polhem, Christopher
SUBJECT AREA: Mining and extraction technology[br]b. 18 December 1661 Tingstade, Gotland, Sweden d. 1751[br]Swedish engineer and inventor.[br]He was the eldest son of Wolf Christopher Polhamma, a merchant. The father died in 1669 and the son was sent by his stepfather to an uncle in Stockholm who found him a place in the Deutsche Rechenschule. After the death of his uncle, he was forced to find employment, which he did with the Biorenklou family near Uppsala where he eventually became a kind of estate bailiff. It was during this period that he started to work with a lathe, a forge and at carpentry, displaying great technical ability. He realized that without further education he had little chance of making anything of his life, and accordingly, in 1687, he registered at the University of Uppsala where he studied astronomy and mathematics, remaining there for three years. He also repaired two astronomical pendulum clocks as well as the decrepit medieval clock in the cathedral. After a year's work he had this clock running properly: this was his breakthrough. He was summoned to Stockholm where the King awarded him a salary of 500 dalers a year as an encouragement to further efforts. Around this time, one of increasing mechanization and when mining was Sweden's principal industry, Pohlem made a model of a hoist frame for mines and the Mines Authority encouraged him to develop his ideas. In 1693 Polhem completed the Blankstot hoist at the Stora Kopparberg mine, which attracted great interest on the European continent.From 1694 to 1696 Polhem toured factories, mills and mines abroad in Germany, Holland, England and France, studying machinery of all kinds and meeting many foreign engineers. In 1698 he was appointed Director of Mining Engineering in Sweden, and in 1700 he became Master of Construction in the Falu Mine. He installed the Karl XII hoist there, powered by moving beams from a distant water-wheel. His plan of 1697 for all the machinery at the Falu mine to be driven by three large and remote water-wheels was never completed.In 1707 he was invited by the Elector of Hanover to visit the mines in the Harz district, where he successfully explained many of his ideas which were adopted by the local engineers. In 1700, in conjunction with Gabriel Stierncrona, he founded the Stiersunds Bruk at Husby in Southern Dalarna, a factory for the mass production of metal goods in iron, steel and bronze. Simple articles such as pans, trays, bowls, knives, scissors and mirrors were made there, together with the more sophisticated Polhem lock and the Stiersunds clock. Production was based on water power. Gear cutting for the clocks, shaping hammers for plates, file cutting and many other operations were all water powered, as was a roller mill for the sheet metal used in the factory. He also designed textile machinery such as stocking looms and spinning frames and machines for the manufacture of ribbons and other things.In many of his ideas Polhem was in advance of his time and Swedish country society was unable to absorb them. This was largely the reason for the Stiersund project being only a partial success. Polhem, too, was of a disputatious nature, self-opinionated almost to the point of conceit. He was a prolific writer, leaving over 20,000 pages of manuscript notes, drafts, essays on a wide range of subjects, which included building, brick-making, barrels, wheel-making, bell-casting, organ-building, methods of stopping a horse from bolting and a curious tap "to prevent serving maids from sneaking wine from the cask", the construction of ploughs and threshing machines. His major work, Kort Berattelse om de Fornamsta Mechaniska Inventioner (A Brief Account of the Most Famous Inventions), was printed in 1729 and is the main source of knowledge about his technological work. He is also known for his "mechanical alphabet", a collection of some eighty wooden models of mechanisms for educational purposes. It is in the National Museum of Science and Technology in Stockholm.[br]Bibliography1729, Kort Berattelse om de Fornamsta Mechaniska Inventioner (A Brief Account of the Most Famous Inventions).Further Reading1985, Christopher Polhem, 1661–1751, TheSwedish Daedalus' (catalogue of a travelling exhibition from the Swedish Institute in association with the National Museum of Science and Technology), Stockholm.IMcN -
115 Titt, John Wallis
[br]b. 1841 Cheriton, Wiltshire, Englandd. May 1910 Warminster, Wiltshire, England[br]English agricultural engineer and millwright who developed a particular form of wind engine.[br]John Wallis Titt grew up on a farm which had a working post-mill, but at 24 years of age he joined the firm of Wallis, Haslam \& Stevens, agricultural engineers and steam engine builders in Basingstoke. From there he went to the millwrighting firm of Brown \& May of Devizes, where he worked for five years.In 1872 he founded his own firm in Warminster, where his principal work as an agricultural engineer was on hay and straw elevators. In 1876 he moved his firm to the Woodcock Ironworks, also in Warminster. There he carried on his work as an agricultural engineer, but he also had an iron foundry. By 1884 the firm was installing water pumps on estates around Warminster, and it was about that time that he built his first wind engines. Between 1884 and 1903, when illness forced his retirement, his wind engines were built primarily with adjustable sails. These wind engines, under the trade marks "Woodcock" and "Simplex", consisted of a lattice tower with the sails mounted on a a ring at the top. The sails were turned to face the wind by means of a fantail geared to the ring or by a wooden vane. The important feature lay in the sails, which were made of canvas on a wood-and-iron frame mounted in a ring. The ends of the sail frames were hinged to the sail circumferences. In the middle of the sail a circular strap was attached so that all the frames had the same aspect for a given setting of the bar. The importance lies in the adjustable sails, which gave the wind engine the ability to work in variable winds.Whilst this was not an original patent of John Wallis Titt, he is known to be the only maker of wind engines in Britain who built his business on this highly efficient form of sail. In design terms it derives from the annular sails of the conventional windmills at Haverhill in Suffolk and Roxwell in Essex. After his retirement, his sons reverted to the production of the fixed-bladed galvanized-iron wind engine.[br]Further ReadingJ.K.Major, 1977, The Windmills of John Wallis Titt, The International Molinological Society.E.Lancaster Burne, 1906, "Wind power", Cassier' Magazine 30:325–6.KM
