81 Smith, Sir Francis Pettit
SUBJECT AREA: Ports and shipping[br]b. 9 February 1808 Copperhurst Farm, near Hythe, Kent, Englandd. 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.[br]Principal Honours and DistinctionsKnighted 1871.Further ReadingObituary, 1874, Illustrated London News (7 February).1856, On the Invention and Progress of the Screw Propeller, London (provides biographical details).Smith and his invention are referred to in papers in Transactions of the Newcomen Society, 14 (1934): 9; 19 (1939): 145–8, 155–7, 161–4, 237–9.LRDBiographical history of technology > Smith, Sir Francis Pettit

82 Whitney, Eli
[br]b. 8 December 1765 Westborough, Massachusetts, USAd. 8 January 1825 New Haven, Connecticut, USA[br]American inventor of the cotton gin and manufacturer of firearms.[br]The son of a prosperous farmer, Eli Whitney as a teenager showed more interest in mechanics than school work. At the age of 15 he began an enterprise business manufacturing nails in his father's workshop, even having to hire help to fulfil his orders. He later determined to acquire a university education and, his father having declined to provide funds, he taught at local schools to obtain the means to attend Leicester Academy, Massachusetts, in preparation for his entry to Yale in 1789. He graduated in 1792 and then decided to study law. He accepted a position in Georgia as a tutor that would have given him time for study; this post did not materialize, but on his journey south he met General Nathanael Greene's widow and the manager of her plantations, Phineas Miller (1764–1803). A feature of agriculture in the southern states was that the land was unsuitable for long-staple cotton but could yield large crops of green-seed cotton. Green-seed cotton was difficult to separate from its seed, and when Whitney learned of the problem in 1793 he quickly devised a machine known as the cotton gin, which provided an effective solution. He formed a partnership with Miller to manufacture the gin and in 1794 obtained a patent. This invention made possible the extraordinary growth of the cotton industry in the United States, but the patent was widely infringed and it was not until 1807, after amendment of the patent laws, that Whitney was able to obtain a favourable decision in the courts and some financial return.In 1798 Whitney was in financial difficulties following the failure of the initial legal action against infringement of the cotton gin patent, but in that year he obtained a government contract to supply 10,000 muskets within two years with generous advance payments. He built a factory at New Haven, Connecticut, and proposed to use a new method of manufacture, perhaps the first application of the system of interchangeable parts. He failed to supply the firearms in the specified time, and in fact the first 500 guns were not delivered until 1801 and the full contract was not completed until 1809.In 1812 Whitney made application for a renewal of his cotton gin patent, but this was refused. In the same year, however, he obtained a second contract from the Government for 15,000 firearms and a similar one from New York State which ensured the success of his business.[br]Further ReadingJ.Mirsky and A.Nevins, 1952, The World of Eli Whitney, New York (a good biography).
