5 Hancock, Thomas
SUBJECT AREA: Chemical technology[br]b. 8 May 1786 Marlborough, Wiltshire, Englandd. 26 March 1865 Stoke Newington, London, England[br]English founder of the British rubber industry.[br]After education at a private school in Marlborough, Hancock spent some time in "mechanical pursuits". He went to London to better himself and c.1819 his interest was aroused in the uses of rubber, which until then had been limited. His first patent, dated 29 April 1820, was for the application of rubber in clothing where some elasticity was useful, such as braces or slip-on boots. He noticed that freshly cut pieces of rubber could be made to adhere by pressure to form larger pieces. To cut up his imported and waste rubber into small pieces, Hancock developed his "masticator". This device consisted of a spiked roller revolving in a hollow cylinder. However, when rubber was fed in to the machine, the product was not the expected shredded rubber, but a homogeneous cylindrical mass of solid rubber, formed by the heat generated by the process and pressure against the outer cylinder. This rubber could then be compacted into blocks or rolled into sheets at his factory in Goswell Road, London; the blocks and sheets could be used to make a variety of useful articles. Meanwhile Hancock entered into partnership with Charles Macintosh in Manchester to manufacture rubberized, waterproof fabrics. Despite these developments, rubber remained an unsatisfactory material, becoming sticky when warmed and losing its elasticity when cold. In 1842 Hancock encountered specimens of vulcanized rubber prepared by Charles Goodyear in America. Hancock worked out for himself that it was made by heating rubber and sulphur, and obtained a patent for the manufacture of the material on 21 November 1843. This patent also included details of a new form of rubber, hardened by heating to a higher temperature, that was later called vulcanite, or ebonite. In 1846 he began making solid rubber tyres for road vehicles. Overall Hancock took out sixteen patents, covering all aspects of the rubber industry; they were a leading factor in the development of the industry from 1820 until their expiry in 1858.[br]Bibliography1857, Personal Narrative of the Origin and Progress of the Caoutchouc or Indiarubber Manufacture in England, London.Further ReadingH.Schurer, 1953, "The macintosh: the paternity of an invention", Transactions of the Newcomen Society 28:77–87.LRD -
6 Hyatt, John Wesley
[br]b. 28 November 1837 Starkey, New York, USAd. 10 May 1920 Short Hills, New Jersey, USA[br]American inventor and the first successful manufacturer of celluloid.[br]Leaving school at the age of 16, Hyatt spent ten years in the printing trade, demonstrating meanwhile a talent for invention. The offer of a prize of $10,000 for finding a substitute for ivory billiard balls stimulated Hyatt to experiment with various materials. After many failures, he arrived at a composition of paper flock, shellac and collodion, which was widely adopted. Noting the "skin" left after evaporating collodion, he continued his experiments, using nitrocellulose as a base for plastic materials, yet he remained largely ignorant of both chemistry and the dangers of this explosive substance. Independently of Parkes in England, he found that a mixture of nitrocellulose, camphor and a little alcohol could, by heating, be made soft enough to mould but became hard at room temperature. Hyatt's first patent for the material, celluloid, was dated 12 July 1870 (US pat. 105338) and was followed by many others for making domestic and decorative articles of celluloid, replacing more expensive natural materials. Manufacture began at Albany in the winter of 1872–3. In 1881 Hyatt and his brother Isiah Smith floated the Hyatt Pure Water Company. By introducing purifying coagulants into flowing water, they avoided the expense and delay of allowing the water to settle in large tanks before filtration. Many towns and paper and woollen mills adopted the new process, and in 1891 it was introduced into Europe. During 1891–2, Hyatt devised a widely used type of roller bearing. Later inventions included a sugar-cane mill, a multistitch sewing machine and a mill for the cold rolling and straightening of steel shafts. It was characteristic of Hyatt's varied inventions that they achieved improved results at less expense.[br]Principal Honours and DistinctionsSociety of Chemical Industry Perkin Medal 1914.Bibliography12 July 1870, US patent no. 105,338 (celluloid).Further ReadingObituary, 1920, Chem.

7 Tompion, Thomas
SUBJECT AREA: Horology[br]baptized 25 July 1639 Ickwell Green, Englandd. 20 November 1713 London, England[br]English clock-and watchmaker of great skill and ingenuity who laid the foundations of his country's pre-eminence in that field.[br]Little is known about Tompion's early life except that he was born into a family of blacksmiths. When he was admitted into the Clockmakers' Company in 1671 he was described as a "Great Clockmaker", which meant a maker of turret clocks, and as these clocks were made of wrought iron they would have required blacksmithing skills. Despite this background, he also rapidly established his reputation as a watchmaker. In 1674 he moved to premises in Water Lane at the sign of "The Dial and Three Crowns", where his business prospered and he remained for the rest of his life. Assisted by journeymen and up to eleven apprentices at any one time, the output from his workshop was prodigious, amounting to over 5,000 watches and 600 clocks. In his lifetime he was famous for his watches, as these figures suggest, but although they are of high quality they do not differ markedly from those produced by other London watchmakers of that period. He is now known more for the limited number of elaborate clocks that he produced, such as the equation clock and the spring-driven clock of a year's duration, which he made for William III. Around 1711 he took into partnership his nephew by marriage, George Graham, who carried on the business after his death.Although Tompion does not seem to have been particularly innovative, he lived at a time when great advances were being made in horology, which his consummate skill as a craftsman enabled him to exploit. In this he was greatly assisted by his association with Robert Hooke, for whom Tompion constructed a watch with a balance spring in 1675; at that time Hooke was trying to establish his priority over Huygens for this invention. Although this particular watch was not successful, it made Tompion aware of the potential of the balance spring and he became the first person in England to apply Huygens's spiral spring to the balance of a watch. Although Thuret had constructed such a watch somewhat earlier in France, the superior quality of Tompion's wheel work, assisted by Hooke's wheel-cutting engine, enabled him to dominate the market. The anchor escapement (which reduced the amplitude of the pendulum's swing) was first applied to clocks around this time and produced further improvements in accuracy which Tompion and other makers were able to utilize. However, the anchor escapement, like the verge escapement, produced recoil (the clock was momentarily driven in reverse). Tompion was involved in attempts to overcome this defect with the introduction of the dead-beat escapement for clocks and the horizontal escapement for watches. Neither was successful, but they were both perfected later by George Graham.[br]Principal Honours and DistinctionsMaster of the Clockmakers' Company 1703.Bibliography1695, with William Houghton and Edward Barlow, British patent no. 344 (for a horizontal escapement).Further ReadingR.W.Symonds, 1951, Thomas Tompion, His Life and Work, London (a comprehensive but now slightly dated account).H.W.Robinson and W.Adams (eds), 1935, The Diary of Robert Hooke (contains many references to Tompion).D.Howse, 1970, The Tompion clocks at Greenwich and the dead-beat escapement', Antiquarian Horology 7:18–34, 114–33.DV
