  • 61 Hornblower, Jonathan

    [br]
    b. 1753 Cornwall (?), England
    d. 1815 Penryn, Cornwall, England
    [br]
    English mining engineer who patented an early form of compound steam engine.
    [br]
    Jonathan came from a family with an engineering tradition: his grandfather Joseph had worked under Thomas Newcomen. Jonathan was the sixth child in a family of thirteen whose names all began with "J". In 1781 he was living at Penryn, Cornwall and described himself as a plumber, brazier and engineer. As early as 1776, when he wished to amuse himself by making a small st-eam engine, he wanted to make something new and wondered if the steam would perform more than one operation in an engine. This was the foundation for his compound engine. He worked on engines in Cornwall, and in 1778 was Engineer at the Ting Tang mine where he helped Boulton \& Watt erect one of their engines. He was granted a patent in 1781 and in that year tried a large-scale experiment by connecting together two engines at Wheal Maid. Very soon John Winwood, a partner in a firm of iron founders at Bristol, acquired a share in the patent, and in 1782 an engine was erected in a colliery at Radstock, Somerset. This was probably not very successful, but a second was erected in the same area. Hornblower claimed greater economy from his engines, but steam pressures at that time were not high enough to produce really efficient compound engines. Between 1790 and 1794 ten engines with his two-cylinder arrangement were erected in Cornwall, and this threatened Boulton \& Watt's near monopoly. At first the steam was condensed by a surface condenser in the bottom of the second, larger cylinder, but this did not prove very successful and later a water jet was used. Although Boulton \& Watt proceeded against the owners of these engines for infringement of their patent, they did not take Jonathan Hornblower to court. He tried a method of packing the piston rod by a steam gland in 1781 and his work as an engineer must have been quite successful, for he left a considerable fortune on his death.

  • 62 Howe, Elias

    [br]
    b. 9 July 1819 Spencer, Massachusetts, USA
    d. 3 October 1867 Bridgeport, Connecticut, USA
    [br]
    American inventor of one of the earliest successful sewing machines.
    [br]
    Son of Elias Howe, a farmer, he acquired his mechanical knowledge in his father's mill. He left school at 12 years of age and was apprenticed for two years in a machine shop in Lowell, Massachusetts, and later to an instrument maker, Ari Davis in Boston, Massachusetts, where his master's services were much in demand by Harvard University. Fired by a desire to invent a sewing machine, he utilized the experience gained in Lowell to devise a shuttle carrying a lower thread and a needle carrying an upper thread to make lock-stitch in straight lines. His attempts were so rewarding that he left his job and was sustained first by his father and then by a partner. By 1845 he had built a machine that worked at 250 stitches per minute, and the following year he patented an improved machine. The invention of the sewing machine had an enormous impact on the textile industry, stimulating demand for cloth because making up garments became so much quicker. The sewing machine was one of the first mass-produced consumer durables and was essentially an American invention. William Thomas, a London manufacturer of shoes, umbrellas and corsets, secured the British rights and persuaded Howe to come to England to apply it to the making of shoes. This Howe did, but he quarrelled with Thomas after less than one year. He returned to America to face with his partner, G.W.Bliss, a bigger fight over his patent (see I.M. Singer), which was being widely infringed. Not until 1854 was the case settled in his favour. This litigation threatened the very existence of the new industry, but the Great Sewing Machine Combination, the first important patent-pooling arrangement in American history, changed all this. For a fee of $5 on every domestically-sold machine and $1 on every exported one, Howe contributed to the pool his patent of 1846 for a grooved eye-pointed needle used in conjunction with a lock-stitch-forming shuttle. Howe's patent was renewed in 1861; he organized and equipped a regiment during the Civil War with the royalties. When the war ended he founded the Howe Machine Company of Bridgeport, Connecticut.

  • 63 Marconi, Marchese Guglielmo

    [br]
    b. 25 April 1874 Bologna, Italy
    d. 20 July 1937 Rome, Italy
    [br]
    Italian radio pioneer whose inventiveness and business skills made radio communication a practical proposition.
    [br]
    Marconi was educated in physics at Leghorn and at Bologna University. An avid experimenter, he worked in his parents' attic and, almost certainly aware of the recent work of Hertz and others, soon improved the performance of coherers and spark-gap transmitters. He also discovered for himself the use of earthing and of elevated metal plates as aerials. In 1895 he succeeded in transmitting telegraphy over a distance of 2 km (1¼ miles), but the Italian Telegraph authority rejected his invention, so in 1896 he moved to England, where he filed the first of many patents. There he gained the support of the Chief Engineer of the Post Office, and by the following year he had achieved communication across the Bristol Channel.
    The British Post Office was also slow to take up his work, so in 1897 he formed the Wireless Telegraph \& Signal Company to work independently. In 1898 he sold some equipment to the British Army for use in the Boer War and established the first permanent radio link from the Isle of Wight to the mainland. In 1899 he achieved communication across the English Channel (a distance of more than 31 miles or 50 km), the construction of a wireless station at Spezia, Italy, and the equipping of two US ships to report progress in the America's Cup yacht race, a venture that led to the formation of the American Marconi Company. In 1900 he won a contract from the British Admiralty to sell equipment and to train operators. Realizing that his business would be much more successful if he could offer his customers a complete radio-communication service (known today as a "turnkey" deal), he floated a new company, the Marconi International Marine Communications Company, while the old company became the Marconi Wireless Telegraph Company.
    His greatest achievement occurred on 12 December 1901, when Morse telegraph signals from a transmitter at Poldhu in Cornwall were received at St John's, Newfoundland, a distance of some 2,100 miles (3,400 km), with the use of an aerial flown by a kite. As a result of this, Marconi's business prospered and he became internationally famous, receiving many honours for his endeavours, including the Nobel Prize for Physics in 1909. In 1904, radio was first used to provide a daily bulletin at sea, and in 1907 a transatlantic wireless telegraphy service was inaugurated. The rescue of 1,650 passengers from the shipwreck of SS Republic in 1909 was the first of many occasions when wireless was instrumental in saving lives at sea, most notable being those from the Titanic on its maiden voyage in April 1912; more lives would have been saved had there been sufficient lifeboats. Marconi was one of those who subsequently pressed for greater safety at sea. In 1910 he demonstrated the reception of long (8 km or 5 miles) waves from Ireland in Buenos Aires, but after the First World War he began to develop the use of short waves, which were more effectively reflected by the ionosphere. By 1918 the first link between England and Australia had been established, and in 1924 he was awarded a Post Office contract for short-wave communication between England and the various parts of the British Empire.
    With his achievements by then recognized by the Italian Government, in 1915 he was appointed Radio-Communications Adviser to the Italian armed forces, and in 1919 he was an Italian delegate to the Paris Peace Conference. From 1921 he lived on his yacht, the Elettra, and although he joined the Fascist Party in 1923, he later had reservations about Mussolini.

  • 64 Menzies, Michael

    [br]
    b. end of the seventeenth century Lanarkshire, Scotland (?)
    d. 13 December 1766 Edinburgh, Scotland
    [br]
    Scottish inventor and lawyer.
    [br]
    Menzies was admitted as a member of the Faculty of Advocates on 31 January 1719. It is evident from his applications for patents that he was more concerned with inventions than the law, however. He took out his first patent in 1734 for a threshing machine in which a number of flails were attached to a horizontal axis, which was moved rapidly forwards and backwards through half a revolution, essentially imitating the action of an ordinary flail. The grain to be threshed was placed on either side.
    Though not a practical success, Menzies's invention seems to have been the first for the mechanical threshing of grain. His idea of imitating non-mechanized action also influenced his invention of a coal cutter, for which he took out a patent in 1761 and which copied miners' tools for obtaining coal. He proposed to carry heavy chains down the pit so that they could be used to give motion to iron picks, saws or other chains with cutting implements. The chains could be set into motion by a steam-engine, by water-or windmills, or by horses gins. Although it is quite obvious that this apparatus could not work, Menzies was the first to have thought of mechanizing coal production in the style that was in use in the late twentieth century. Subsequent to Menzies's proposal, many inventors at varying intervals followed this direction until the problem was finally solved one century later by, among others, W.E. Garforth.
    Menzies had successfully used the power of a steam-engine on the Wear eight years beforehand, when he obtained a patent for raising coal. According to his device a descending bucket filled with water raised a basket of coals, while a steam-engine pumped the water back to the surface; the balance-tub system, in various forms, quickly spread to other coalfields. Menzies's patent from 1750 for improved methods of carrying the coals from the coalface to the pit-shaft had also been of considerable influence: this device employed self-acting inclined planes, whereon the descending loaded wagons hauled up the empty ones.

    SUBJECT AREA: Ports and shipping
    [br]
    b. 9 February 1808 Copperhurst Farm, near Hythe, Kent, England
    d. 12 February 1874 South Kensington, London, England
    [br]
    English inventor of the screw propeller.
    [br]
    Smith was the only son of Charles Smith, Postmaster at Hythe, and his wife Sarah (née Pettit). After education at a private school in Ashford, Kent, he took to farming, first on Romney Marsh, then at Hendon, Middlesex. As a boy, he showed much skill in the construction of model boats, especially in devising their means of propulsion. He maintained this interest into adult life and in 1835 he made a model propelled by a screw driven by a spring. This worked so well that he became convinced that the screw propeller offered a better method of propulsion than the paddle wheels that were then in general use. This notion so fired his enthusiasm that he virtually gave up farming to devote himself to perfecting his invention. The following year he produced a better model, which he successfully demonstrated to friends on his farm at Hendon and afterwards to the public at the Adelaide Gallery in London. On 31 May 1836 Smith was granted a patent for the propulsion of vessels by means of a screw.
    The idea of screw propulsion was not new, however, for it had been mooted as early as the seventeenth century and since then several proposals had been advanced, but without successful practical application. Indeed, simultaneously but quite independently of Smith, the Swedish engineer John Ericsson had invented the ship's propeller and obtained a patent on 13 July 1836, just weeks after Smith. But Smith was completely unaware of this and pursued his own device in the belief that he was the sole inventor.
    With some financial and technical backing, Smith was able to construct a 10 ton boat driven by a screw and powered by a steam engine of about 6 hp (4.5 kW). After showing it off to the public, Smith tried it out at sea, from Ramsgate round to Dover and Hythe, returning in stormy weather. The screw performed well in both calm and rough water. The engineering world seemed opposed to the new method of propulsion, but the Admiralty gave cautious encouragement in 1839 by ordering that the 237 ton Archimedes be equipped with a screw. It showed itself superior to the Vulcan, one of the fastest paddle-driven ships in the Navy. The ship was put through its paces in several ports, including Bristol, where Isambard Kingdom Brunel was constructing his Great Britain, the first large iron ocean-going vessel. Brunel was so impressed that he adapted his ship for screw propulsion.
    Meanwhile, in spite of favourable reports, the Admiralty were dragging their feet and ordered further trials, fitting Smith's four-bladed propeller to the Rattler, then under construction and completed in 1844. The trials were a complete success and propelled their lordships of the Admiralty to a decision to equip twenty ships with screw propulsion, under Smith's supervision.
    At last the superiority of screw propulsion was generally accepted and virtually universally adopted. Yet Smith gained little financial reward for his invention and in 1850 he retired to Guernsey to resume his farming life. In 1860 financial pressures compelled him to accept the position of Curator of Patent Models at the Patent Museum in South Kensington, London, a post he held until his death. Belated recognition by the Government, then headed by Lord Palmerston, came in 1855 with the grant of an annual pension of £200. Two years later Smith received unofficial recognition when he was presented with a national testimonial, consisting of a service of plate and nearly £3,000 in cash subscribed largely by the shipbuilding and engineering community. Finally, in 1871 Smith was honoured with a knighthood.

  • 66 Watt, James

    [br]
    b. 19 January 1735 Greenock, Renfrewshire, Scotland
    d. 19 August 1819 Handsworth Heath, Birmingham, England
    [br]
    Scottish engineer and inventor of the separate condenser for the steam engine.
    [br]
    The sixth child of James Watt, merchant and general contractor, and Agnes Muirhead, Watt was a weak and sickly child; he was one of only two to survive childhood out of a total of eight, yet, like his father, he was to live to an age of over 80. He was educated at local schools, including Greenock Grammar School where he was an uninspired pupil. At the age of 17 he was sent to live with relatives in Glasgow and then in 1755 to London to become an apprentice to a mathematical instrument maker, John Morgan of Finch Lane, Cornhill. Less than a year later he returned to Greenock and then to Glasgow, where he was appointed mathematical instrument maker to the University and was permitted in 1757 to set up a workshop within the University grounds. In this position he came to know many of the University professors and staff, and it was thus that he became involved in work on the steam engine when in 1764 he was asked to put in working order a defective Newcomen engine model. It did not take Watt long to perceive that the great inefficiency of the Newcomen engine was due to the repeated heating and cooling of the cylinder. His idea was to drive the steam out of the cylinder and to condense it in a separate vessel. The story is told of Watt's flash of inspiration as he was walking across Glasgow Green one Sunday afternoon; the idea formed perfectly in his mind and he became anxious to get back to his workshop to construct the necessary apparatus, but this was the Sabbath and work had to wait until the morrow, so Watt forced himself to wait until the Monday morning.
    Watt designed a condensing engine and was lent money for its development by Joseph Black, the Glasgow University professor who had established the concept of latent heat. In 1768 Watt went into partnership with John Roebuck, who required the steam engine for the drainage of a coal-mine that he was opening up at Bo'ness, West Lothian. In 1769, Watt took out his patent for "A New Invented Method of Lessening the Consumption of Steam and Fuel in Fire Engines". When Roebuck went bankrupt in 1772, Matthew Boulton, proprietor of the Soho Engineering Works near Birmingham, bought Roebuck's share in Watt's patent. Watt had met Boulton four years earlier at the Soho works, where power was obtained at that time by means of a water-wheel and a steam engine to pump the water back up again above the wheel. Watt moved to Birmingham in 1774, and after the patent had been extended by Parliament in 1775 he and Boulton embarked on a highly profitable partnership. While Boulton endeavoured to keep the business supplied with capital, Watt continued to refine his engine, making several improvements over the years; he was also involved frequently in legal proceedings over infringements of his patent.
    In 1794 Watt and Boulton founded the new company of Boulton \& Watt, with a view to their retirement; Watt's son James and Boulton's son Matthew assumed management of the company. Watt retired in 1800, but continued to spend much of his time in the workshop he had set up in the garret of his Heathfield home; principal amongst his work after retirement was the invention of a pantograph sculpturing machine.
    James Watt was hard-working, ingenious and essentially practical, but it is doubtful that he would have succeeded as he did without the business sense of his partner, Matthew Boulton. Watt coined the term "horsepower" for quantifying the output of engines, and the SI unit of power, the watt, is named in his honour.

  • 68 Ayrton, William Edward

    [br]
    b. 14 September 1847 London, England
    d. 8 November 1908 London, England
    [br]
    English physicist, inventor and pioneer in technical education.
    [br]
    After graduating from University College, London, Ayrton became for a short time a pupil of Sir William Thomson in Glasgow. For five years he was employed in the Indian Telegraph Service, eventually as Superintendent, where he assisted in revolutionizing the system, devising methods of fault detection and elimination. In 1873 he was invited by the Japanese Government to assist as Professor of Physics and Telegraphy in founding the Imperial College of Engineering in Tokyo. There he created a teaching laboratory that served as a model for those he was later to organize in England and which were copied elsewhere. It was in Tokyo that his joint researches with Professor John Perry began, an association that continued after their return to England. In 1879 he became Professor of Technical Physics at the City and Guilds Institute in Finsbury, London, and later was appointed Professor of Physics at the Central Institution in South Kensington.
    The inventions of Avrton and Perrv included an electric tricycle in 1882, the first practicable portable ammeter and other electrical measuring instruments. By 1890, when the research partnership ended, they had published nearly seventy papers in their joint names, the emphasis being on a mathematical treatment of subjects including electric motor design, construction of electrical measuring instruments, thermodynamics and the economical use of electric conductors. Ayrton was then employed as a consulting engineer by government departments and acted as an expert witness in many important patent cases.

    [br]
    b. 11 December 1856 Birkenhead, England
    d. 17 October 1921 London, England
    [br]
    English co-inventor of the " viscose rayon " process for making artificial silk.
    [br]
    Bevan began his working life as a chemist in a soap works at Runcorn, but later studied chemistry at Owens College, Manchester. It was there that he met and formed a friendship with C.F. Cross, with whom he started to work on cellulose. Bevan moved to a paper mill in Scotland but then went south to London, where he and Cross set up a partnership in 1885 as consulting and analytical chemists. Their work was mainly concerned with the industrial utilization of cellulose, and with the problems of the paper and jute industries. Their joint publication, A Text-book of Paper-making, which first appeared in 1888 and went into several editions, became the standard reference and textbook on the subject. The book has a long introductory chapter on cellulose.
    In 1892 Cross, Bevan and Clayton Beadle discovered viscose, or sodium cellulose xanthate, and took out the patent which was to be the foundation of the "viscose rayon" industry. They had their own laboratory at Station Avenue, Kew Gardens, where they carried out much work that eventually resulted in viscose: cellulose, usually in the form of wood pulp, was treated first with caustic soda and then with carbon disulphide to form the xanthate, which was then dissolved in a solution of dilute caustic soda to produce a viscous liquid. After being aged, the viscose was extruded through fine holes in a spinneret and coagulated in a dilute acid to regenerate the cellulose as spinnable fibres. At first there was no suggestion of spinning it into fibre, but the hope was to use it for filaments in incandescent electric light bulbs. The sheen on the fibres suggested their possible use in textiles and the term "artificial silk" was later introduced. Cross and Bevan also discovered the acetate "Celanese", which was cellulose triacetate dissolved in acetone and spun in air, but both inventions needed much development before they could be produced commercially.
    In 1892 Bevan turned from cellulose to food and drugs and left the partnership to become Public Analyst to Middlesex County Council, a post he held until his death, although in 1895 he and Cross published their important work Cellulose. He was prominent in the affairs of the Society of Public Analysts and became one of its officials.

  • 70 Budding, Edwin Beard

    [br]
    b. c.1796 Bisley (?), Gloucestershire, England
    d. 1846 Dursley, Gloucestershire, England
    [br]
    English inventor of the lawn mower.
    [br]
    Budding was an engineer who described himself as a mechanic on his first patent papers and as a manager in later applications.
    A rotary machine had been developed at Brimscombe Mill in Stroud for cutting the pile on certain clothes and Budding saw the potential of this principle for a machine for cutting grass on lawns. It is not clear whether Budding worked for the Lewis family, who owned the mill, or whether he saw the machines during their manufacture at the Phoenix Foundry. At the age of 35 Budding entered into partnership with John Ferrabee, who had taken out a lease on Thrupp Mill. They reached an agreement in which Ferrabee would pay to obtain letter patent on the mower and would cover all the development costs, after which they would have an equal share in the profits. The agreement also allowed Ferrabee to license the manufacture of the machine and in 1832 he negotiated with the agricultural manufacturer Ransomes, allowing them to manufacture the mower.
    Budding invented a screw-shifting spanner at a time when he might have been working as a mechanic at Thrupp Mill. He later rented a workshop in which he produced Pepperbox pistols. In the late 1830s he moved to Dursley, where he became Manager for Mr G.Lister, who made clothing machinery. Together they patented an improved method of making cylinders for carding engines, but Budding required police protection from those who saw their jobs threatened by the device. He made no fortune from his inventions and died at the age of 50.

    [br]
    b. 31 March 1854 Glasgow, Scotland
    d. 12 November 1932 Ewhurst, Surrey, England
    [br]
    Scottish mechanical engineer, inventor of the two-stroke internal combustion engine.
    [br]
    Clerk began his engineering training at about the age of 15 in the drawing office of H.O.Robinson \& Company, Glasgow, and in his father's works. Meanwhile, he studied at the West of Scotland Technical College and then, from 1871 to 1876, at Anderson's College, Glasgow, and at the Yorkshire College of Science, Leeds. Here he worked under and then became assistant to the distinguished chemist T.E.Thorpe, who set him to work on the fractional distillation of petroleum, which was to be useful to him in his later work. At that time he had intended to become a chemical engineer, but seeing a Lenoir gas engine at work, after his return to Glasgow, turned his main interest to gas and other internal combustion engines. He pursued his investigations first at Thomson, Sterne \& Company (1877–85) and then at Tangyes of Birmingham (1886–88. In 1888 he began a lifelong partnership in Marks and Clerk, consulting engineers and patent agents, in London.
    Beginning his work on gas engines in 1876, he achieved two patents in the two following years. In 1878 he made his principal invention, patented in 1881, of an engine working on the two-stroke cycle, in which the piston is powered during each revolution of the crankshaft, instead of alternate revolutions as in the Otto four-stroke cycle. In this engine, Clerk introduced supercharging, or increasing the pressure of the air intake. Many engines of the Clerk type were made but their popularity waned after the patent for the Otto engine expired in 1890. Interest was later revived, particularly for application to large gas engines, but Clerk's engine eventually came into its own where simple, low-power motors are needed, such as in motor cycles or motor mowers.
    Clerk's work on the theory and design of gas engines bore fruit in the book The Gas Engine (1886), republished with an extended text in 1909 as The Gas, Petrol and Oil Engine; these and a number of papers in scientific journals won him international renown. During and after the First World War, Clerk widened the scope of his interests and served, often as chairman, on many bodies in the field of science and industry.

    English designer and glider aeronaut.
    [br]
    He was educated at HMS Britannia Royal Naval College, Dartmouth, from 1880 to 1882. He sailed on HMS Duke of Wellington, Agincourt, Northampton and other ships and resigned from the navy on 18 April 187 after seven years at sea. In June 1887 he was apprenticed at Randolph, Elder \& Co.'s shipyard at Govan, and was then an apprentice moulder at Cairn \& Co., Glasgow. For some time he "studied" at London University (though there is no official record of his doing so) while living with his sister at Phillbeck Gardens, South Kensington. In May 1890 he was working for John H.Biles, Manager of the Southampton Naval Works Ltd. Biles was later appointed Professor of Naval Architecture at Glasgow University with Pilcher as his Assistant Lecturer. In 1895 he was building his first glider, the Bat, which was built mainly of Riga pine and weighed 44 lb (20 kg). In succeeding months he travelled to Lichterfelde to study the gliders made by the German Lilienthal and built a further three machines, the Beetle, the Gull and the Hawk. In 1896 he applied for his only aeronautical patent, for "Improved flying and soaring machines", which was accepted on March 1897. In April 1896 he resigned his position at Glasgow University to become Assistant to Sir Hiram Maxim, who was also doing experiments with flying machines at his Nordenfeld Guns and Ammunition Co. Ltd at Crayford. He took up residence in Artillery Mansions, Victoria Street, later taken over by Vickers Ltd. Maxim had a hangar at Upper Lodge Farm, Austin Eynsford, Kent: using this, Pilcher reached a height of 12 ft (3.66m) in 1899 with a cable launch. He planned to build a 2 hp (1.5 kW) petrol engine In September 1899 he went to stay with Lord Braye at Stanford Hall, Northamptonshire, where many people came to see his flying machine, a triplane. The weather was far from ideal, windy and raining, but Pilcher would not disappoint them. A bracing wire broke, the tail collapsed and the pilot crashed to the ground suffering two broken legs and concussion. He did not regain consciousness and died the following day. He was buried in Brompton Cemetery.

    [br]
    b. 22 March 1840 Cincinnati, Ohio, USA
    d. 18 July 1926
    [br]
    American mechanical engineer, pioneer in experiments with magnetic recording.
    [br]
    Of English descent, Smith embarked on an education in mechanical engineering, graduating from West Jersey Academy, Bridgeton, New Jersey, in 1859. In 1863 he established a machine shop in Bridgeton, New Jersey, that became the Ferracute Machine Company in 1877, eventually specializing in the manufacture of presses for metalworking. He seems to have subscribed to design principles considered modern even in the 1990s, "always giving attention to the development of artistic form in combination with simplicity, and with massive strength where required" (bibliographic reference below). He was successful in his business, and developed and patented a large number of mechanical constructions.
    Inspired by the advent of the phonograph of Edison, in 1878 Smith obtained the tin-foil mechanical phonograph, analysed its shortcomings and performed some experiments in magnetic recording. He filed a caveat in the US Patent Office in order to be protected while he "reduced the invention to practice". However, he did not follow this trail. When there was renewed interest in practical sound recording and reproduction in 1888 (the constructions of Berliner and Bell \& Tainter), Smith published an account of his experiments in the journal Electrical World. In a corrective letter three weeks later it is clear that he was aware of the physical requirements for the interaction between magnetic coil and magnetic medium, but his publications also indicate that he did not as such obtain reproduction of recorded sound.
    Smith did not try to develop magnetic recording, but he felt it imperative that he be given credit for conceiving the idea of it. When accounts of Valdemar Poulsen's work were published in 1900, Smith attempted to prove some rights in the invention in the US Patent Office, but to no avail.
    He was a highly respected member of both his community and engineering societies, and in later life became interested in the anti-slavery cause that had also been close to the heart of his parents, as well as in the YMCA movement and in women's suffrage.
    [br]
    Bibliography
    Apart from numerous technical papers, he wrote the book Press Working of Metals, 1896. His accounts on the magnetic recording experiments were "Some possible forms of phonograph", Electrical World (8 September 1888): 161 ff, and "Letter to the Editor", Electrical World (29 September 1888): 179.

    SUBJECT AREA: Textiles
    [br]
    fl. c. 1801 London, England
    [br]
    English patentee of one of the first significant machines for heckling flax.
    [br]
    The flax plant passes through many stages before its fibres are prepared for spinning. The woody pith surrounding the fibres is first softened by rotting or "retting", and is then removed by beating or "scutching". This leaves the fibres in a tight bunch, as they have grown to form the stem of the plant. Hackling or heckling, the next process, separates the fibres from each other. In hand processes this was done by pulling the fibres across a board of steel spikes, or sometimes a form of comb was pulled through them.
    In 1795 Sellers and Standage patented a method of heckling in which the flax was pulled by hand through stationary vertical teeth, but much more significant was the patent of 1801 of A.Thompson of London. The length of the fibres in a bundle of flax will vary considerably, therefore the distance between the point where the fibres pass out to be combed and the point where they can be put through another roller or gripper must be greater than the longest fibres, requiring some method of support in between. Thompson used a pair of chain gills for this purpose. These consist of rows of teeth mounted on a continuous chain or belt which moves around while the fibres pass through the teeth in the vertical position. The longer fibres are pulled through the teeth by the drawing rollers at the front, while the shorter ones are held steady by the teeth and presented to the rollers later; thus the teeth both support the fibres and heckle them at the same time. Following this process the fibres can be drawn and spun.

  • 76 Barlow, Edward

    SUBJECT AREA: Horology
    [br]
    baptized 15 December 1636 near Warrington, Cheshire, England d. 1716
    [br]
    English priest and mechanician who invented rack striking, repeating mechanisms for clocks and watches and, with others, patented a horizontal escapement for watches.
    [br]
    Barlow was the son of Edward Booth, but he adopted the surname of his godfather, the Benedictine monk Ambrose Barlow, as a condition of his will. In 1659 he entered the English College at Lisbon, and after being ordained a priest he was sent to the English mission. There he resided at Parkhall in Lancashire, the seat of Mr Houghton, with whom he later collaborated on the horizontal escapement.
    At a time when it was difficult to produce a light to examine the dial of a clock or watch at night, a mechanism that would indicate the hours and subdivisions of the hour audibly and at will was highly desirable. The count wheel, which had been used from the earliest times to control the striking of a clock, was unsuitable for this purpose as it struck the hours in sequence. If the mechanism was set off manually to determine the time, the strike would no longer correspond with the indications on the dial. In 1675 Barlow invented rack striking, where the hour struck was determined solely by the position of the hour hand. With this mechanism it was therefore possible to repeat the hour at will, without upsetting the sequence of striking. In 1687 Barlow tried to patent a method of repeating for watches, but it was rejected by James II in favour of a system produced by the watchmaker Daniel Quare and which was simpler to operate. He was successful in obtaining a patent for a horizontal escapement for watches in 1695, in collaboration with William Hough ton and Thomas Tompion. Although this escapement was little used, it can be regarded as the forerunner of the cylinder escapement that George Graham introduced c. 1725.

  • 77 Berliner, Emile

    SUBJECT AREA: Recording
    [br]
    b. 20 May 1851 Hannover, Germany
    d. 3 August 1929 Montreal, Canada
    [br]
    German (naturalized American) inventor, developer of the disc record and lateral mechanical replay.
    [br]
    After arriving in the USA in 1870 and becoming an American citizen, Berliner worked as a dry-goods clerk in Washington, DC, and for a period studied electricity at Cooper Union for the Advancement of Science and Art, New York. He invented an improved microphone and set up his own experimental laboratory in Washington, DC. He developed a microphone for telephone use and sold the rights to the Bell Telephone Company. Subsequently he was put in charge of their laboratory, remaining in that position for eight years. In 1881 Berliner, with his brothers Joseph and Jacob, founded the J.Berliner Telephonfabrik in Hanover, the first factory in Europe specializing in telephone equipment.
    Inspired by the development work performed by T.A. Edison and in the Volta Laboratory (see C.S. Tainter), he analysed the existing processes for recording and reproducing sound and in 1887 developed a process for transferring lateral undulations scratched in soot into an etched groove that would make a needle and diaphragm vibrate. Using what may be regarded as a combination of the Phonautograph of Léon Scott de Martinville and the photo-engraving suggested by Charles Cros, in May 1887 he thus demonstrated the practicability of the laterally recorded groove. He termed the apparatus "Gramophone". In November 1887 he applied the principle to a glass disc and obtained an inwardly spiralling, modulated groove in copper and zinc. In March 1888 he took the radical step of scratching the lateral vibrations directly onto a rotating zinc disc, the surface of which was protected, and the subsequent etching created the groove. Using well-known principles of printing-plate manufacture, he developed processes for duplication by making a negative mould from which positive copies could be pressed in a thermoplastic compound. Toy gramophones were manufactured in Germany from 1889 and from 1892–3 Berliner manufactured both records and gramophones in the USA. The gramophones were hand-cranked at first, but from 1896 were based on a new design by E.R. Johnson. In 1897–8 Berliner spread his activities to England and Germany, setting up a European pressing plant in the telephone factory in Hanover, and in 1899 a Canadian company was formed. Various court cases over patents removed Berliner from direct running of the reconstructed companies, but he retained a major economic interest in E.R. Johnson's Victor Talking Machine Company. In later years Berliner became interested in aeronautics, in particular the autogiro principle. Applied acoustics was a continued interest, and a tile for controlling the acoustics of large halls was successfully developed in the 1920s.

    [br]
    b. unknown
    d. 1849 England
    [br]
    English cooper, inventor of a gas vacuum engine.
    [br]
    Between the years 1823 and 1833, Brown achieved a number of a firsts as a pioneer of internal-combustion engines. In 1824 he built a full-scale working model of a pumping engine; in 1826, a vehicle fitted with a gas vacuum engine ascended Shooters Hill in Kent; and in 1827 he conducted trials of a motor-driven boat on the Thames that were witnessed by Lords of the Admiralty. The principle of Brown's engine had been demonstrated by Cecil in 1820. A burning gas flame was extinguished within a closed cylinder, creating a partial vacuum; atmospheric pressure was then utilized to produce the working stroke. By 1832 a number of Brown's engines in use for pumping water were reported, the most notable being at Croydon Canal. However, high fuel consumption and running costs prevented a wide acceptance of Brown's engines, and a company formed in 1825 was dissolved only two years later. Brown continued alone with his work until his death.

  • 79 Cookworthy, William

    [br]
    b. 1705 Kings bridge, Devon, England
    d. 16 October 1780 Plymouth, England
    [br]
    English pioneer of porcelain manufacture in England.
    [br]
    The family fortunes having been extinguished by the South Sea Bubble of 1720, Cookworthy and his brother had to fend for themselves. They set up, and succeeded, in the pharmacy trade. At the age of 31, however, William left the business, and after a period of probation he became a minister in the Society of Friends. In a letter of 5 May 1745, Cookworthy mentions some samples of kaolin and china or growan stone that had been brought to him from Virginia. He found similar materials at Treginning Hill in Cornwall, and between 1755 and 1758 he found sufficiently pure china clay and china stone to make a pure white porcelain. Cookworthy took out a patent for his discovery in 1768 which covered the manufacture of porcelain from moonstone or growan and growan clay, with a glaze made from china stone to which lime and fern ash or magnesia alba (basic carbonate of magnesium) were added. Cookworthy's experiments had been carried out on the property of Lord Camelford, who later assisted him, in the company of other Quakers, in setting up a works at Coxside, Plymouth, to manufacture the ware; the works employed between fifty and sixty people. In the absence of coal, Cookworthy resorted to wood as fuel, but this was scarce, so in 1770 he transferred his operation to Castle Green, Bristol. However, he had no greater success there, and in 1773 he sold the entire interest in porcelain manufacture to Richard Champion (1743–91), although Cookworthy and his heirs were to receive royalties for ninety-nine years. Champion, who had been working with Cookworthy since 1764 and was active in Bristol city affairs, continued the firm as Richard Champion \& Co., but when in 1775 Champion tried to renew Cookworthy's patent, Wedgwood and other Staffordshire potters challenged him. After litigation, the use of kaolin and china stone was thrown open to general use. The Staffordshire potters made good use of this new-found freedom and Champion was forced to sell the patent to them and dispose of his factory the following year. The potters of Staffordshire said of Cookworthy, "the greatest service ever conferred by one person on the pottery manufacturers is that of making them acquainted with china clay".

  • 80 Cross, Charles Frederick

    [br]
    b. 11 December 1855 Brentwood, Middlesex, England
    d. 15 April 1935 Hove, England
    [br]
    English chemist who contributed to the development of viscose rayon from cellulose.
    [br]
    Cross was educated at the universities of London, Zurich and Manchester. It was at Owens College, Manchester, that Cross first met E.J. Bevan and where these two first worked together on the nature of cellulose. After gaining some industrial experience, Cross joined Bevan to set up a partnership in London as analytical and consulting chemists, specializing in the chemistry and technology of cellulose and lignin. They were at the Jodrell laboratory, Kew Gardens, for a time and then set up their own laboratory at Station Avenue, Kew Gardens. In 1888, the first edition of their joint publication A Textbook of Paper-making, appeared. It went into several editions and became the standard reference and textbook on the subject. The long introductory chapter is a discourse on cellulose.
    In 1892, Cross, Bevan and Clayton Beadle took out their historic patent on the solution and regeneration of cellulose. The modern artificial-fibre industry stems from this patent. They made their discovery at New Court, Carey Street, London: wood-pulp (or another cheap form of cellulose) was dissolved in a mixture of carbon disulphide and aqueous alkali to produce sodium xanthate. After maturing, it was squirted through fine holes into dilute acid, which set the liquid to give spinnable fibres of "viscose". However, it was many years before the process became a commercial operation, partly because the use of a natural raw material such as wood involved variations in chemical content and each batch might react differently. At first it was thought that viscose might be suitable for incandescent lamp filaments, and C.H.Stearn, a collaborator with Cross, continued to investigate this possibility, but the sheen on the fibres suggested that viscose might be made into artificial silk. The original Viscose Spinning Syndicate was formed in 1894 and a place was rented at Erith in Kent. However, it was not until some skeins of artificial silk (a term to which Cross himself objected) were displayed in Paris that textile manufacturers began to take an interest in it. It was then that Courtaulds decided to investigate this new fibre, although it was not until 1904 that they bought the English patents and developed the first artificial silk that was later called "rayon". Cross was also concerned with the development of viscose films and of cellulose acetate, which became a rival to rayon in the form of "Celanese". He retained his interest in the paper industry and in publishing, in 1895 again collaborating with Bevan and publishing a book on Cellulose and other technical articles. He was a cultured man and a good musician. He was elected a Fellow of the Royal Society in 1917.
