82 Appleby, John F.
SUBJECT AREA: Agricultural and food technology[br]b. 1840 New York, US Ad. ? USA[br]American inventor of the knotting mechanism used on early binders and still found on modern baling machines.[br]As a young man John Appleby worked as a labourer for a farmer near Whitewater in Wisconsin. He was 18 when the farmer bought a new reaping machine. Appleby believed that the concept had not been progressed far enough and that the machine should be able to bind sheaths as well as to cut the corn. It is claimed that while watching a dog playing with a skipping rope he noticed a particular knot created as the dog removed its head from the loop that had passed over it, and recognized the potential of the way in which this knot had been formed. From a piece of apple wood he carved a device that would produce the knot he had seen. A local school teacher backed Appleby's idea with a $50 loan, but the American Civil War and service in the Union Army prevented any further development until 1869 when he took out a patent on a wire-tying binder. A number of the devices were made for him by a company in Beloit. Trials of wire binders held in 1873 highlighted the danger of small pieces of wire caught up in the hay leading to livestock losses. Appleby looked again at the possibility of twine. In 1875 he successfully operated a machine and the following season four were in operation. A number of other developments, not least Behel's "bill hook" knotting device, were also to have an influence in the final development of Appleby's twine-tying binder. As so often happens, it was the vision of the entrepreneur which ultimately led to the success of Appleby's device. In 1877 Appleby persuaded William Deering to produce and market his binder, and 3,000 twine binders, together with the twine produced for them, were put on the market in 1880, with immediate success. Over the next dozen years all harvesting-machine manufacturers adopted the idea, under licence to Appleby.[br]Further ReadingG.Quick and W.Buchele, 1978, The Grain Harvesters, American Society of Agricultural Engineers (provides an account of the development of harvesting machinery and the various tying devices developed for them).1927, "Twine knotter history", Wisconsin Magazine of History (a more specific account).AP -
83 Brush, Charles Francis
[br]b. 17 March 1849 Euclid, Michigan, USAd. 15 June 1929 Cleveland, Ohio, USA[br]American engineer, inventor of a multiple electric arc lighting system and founder of the Brush Electric Company.[br]Brush graduated from the University of Michigan in 1869 and worked for several years as a chemist. Believing that electric arc lighting would be commercially successful if the equipment could be improved, he completed his first dynamo in 1875 and a simplified arc lamp. His original system operated a maximum of four lights, each on a separate circuit, from one dynamo. Brush envisaged a wider market for his product and by 1879 had available on arc lighting system principally intended for street and other outdoor illumination. He designed a dynamo that generated a high voltage and which, with a carbon-pile regulator, provided an almost constant current permitting the use of up to forty lamps on one circuit. He also improved arc lamps by incorporating a slipping-clutch regulating mechanism and automatic means of bringing into use a second set of carbons, thereby doubling the period between replacements.Brush's multiple electric arc lighting system was first demonstrated in Cleveland and by 1880 had been adopted in a number of American cities, including New York, Boston and Philadelphia. It was also employed in many European towns until incandescent lamps, for which the Brush dynamo was unsuitable, came into use. To market his apparatus, Brush promoted local lighting companies and thereby secured local capital.[br]Principal Honours and DistinctionsChevalier de la Légion d'honneur 1881.

84 Hetzel, Max
[br]b. 5 March 1921 Basle, Switzerland[br]Swiss electrical engineer who invented the tuning-fork watch.[br]Hetzel trained as an electrical engineer at the Federal Polytechnic in Zurich and worked for several years in the field of telecommunications before joining the Bulova Watch Company in 1950. At that time several companies were developing watches with electromagnetically maintained balances, but they represented very little advance on the mechanical watch and the mechanical switching mechanism was unreliable. In 1952 Hetzel started work on a much more radical design which was influenced by a transistorized tuning-fork oscillator that he had developed when he was working on telecommunications. Tuning forks, whose vibrations were maintained electromagnetically, had been used by scientists during the nineteenth century to measure small intervals of time, but Niaudet- Breguet appears to have been the first to use a tuning fork to control a clock. In 1866 he described a mechanically operated tuning-fork clock manufactured by the firm of Breguet, but it was not successful, possibly because the fork did not compensate for changes in temperature. The tuning fork only became a precision instrument during the 1920s, when elinvar forks were maintained in vibration by thermionic valve circuits. Their primary purpose was to act as frequency standards, but they might have been developed into precision clocks had not the quartz clock made its appearance very shortly afterwards. Hetzel's design was effectively a miniaturized version of these precision devices, with a transistor replacing the thermionic valve. The fork vibrated at a frequency of 360 cycles per second, and the hands were driven mechanically from the end of one of the tines. A prototype was working by 1954, and the watch went into production in 1960. It was sold under the tradename Accutron, with a guaranteed accuracy of one minute per month: this was a considerable improvement on the performance of the mechanical watch. However, the events of the 1920s were to repeat themselves, and by the end of the decade the Accutron was eclipsed by the introduction of quartz-crystal watches.[br]Principal Honours and DistinctionsNeuchâtel Observatory Centenary Prize 1958.

85 Maxim, Sir Hiram Stevens
[br]b. 5 February 1840 Brockway's Mills, Maine, USAd. 24 November 1916 Streatham, London, England[br]American (naturalized British) inventor; designer of the first fully automatic machine gun and of an experimental steam-powered aircraft.[br]Maxim was born the son of a pioneer farmer who later became a wood turner. Young Maxim was first apprenticed to a carriage maker and then embarked on a succession of jobs before joining his uncle in his engineering firm in Massachusetts in 1864. As a young man he gained a reputation as a boxer, but it was his uncle who first identified and encouraged Hiram's latent talent for invention.It was not, however, until 1878, when Maxim joined the first electric-light company to be established in the USA, as its Chief Engineer, that he began to make a name for himself. He developed an improved light filament and his electric pressure regulator not only won a prize at the first International Electrical Exhibition, held in Paris in 1881, but also resulted in his being made a Chevalier de la Légion d'honneur. While in Europe he was advised that weapons development was a more lucrative field than electricity; consequently, he moved to England and established a small laboratory at Hatton Garden, London. He began by investigating improvements to the Gatling gun in order to produce a weapon with a faster rate of fire and which was more accurate. In 1883, by adapting a Winchester carbine, he successfully produced a semi-automatic weapon, which used the recoil to cock the gun automatically after firing. The following year he took this concept a stage further and produced a fully automatic belt-fed weapon. The recoil drove barrel and breechblock to the vent. The barrel then halted, while the breechblock, now unlocked from the former, continued rearwards, extracting the spent case and recocking the firing mechanism. The return spring, which it had been compressing, then drove the breechblock forward again, chambering the next round, which had been fed from the belt, as it did so. Keeping the trigger pressed enabled the gun to continue firing until the belt was expended. The Maxim gun, as it became known, was adopted by almost every army within the decade, and was to remain in service for nearly fifty years. Maxim himself joined forces with the large British armaments firm of Vickers, and the Vickers machine gun, which served the British Army during two world wars, was merely a refined version of the Maxim gun.Maxim's interests continued to occupy several fields of technology, including flight. In 1891 he took out a patent for a steam-powered aeroplane fitted with a pendulous gyroscopic stabilizer which would maintain the pitch of the aeroplane at any desired inclination (basically, a simple autopilot). Maxim decided to test the relationship between power, thrust and lift before moving on to stability and control. He designed a lightweight steam-engine which developed 180 hp (135 kW) and drove a propeller measuring 17 ft 10 in. (5.44 m) in diameter. He fitted two of these engines into his huge flying machine testrig, which needed a wing span of 104 ft (31.7 m) to generate enough lift to overcome a total weight of 4 tons. The machine was not designed for free flight, but ran on one set of rails with a second set to prevent it rising more than about 2 ft (61 cm). At Baldwyn's Park in Kent on 31 July 1894 the huge machine, carrying Maxim and his crew, reached a speed of 42 mph (67.6 km/h) and lifted off its rails. Unfortunately, one of the restraining axles broke and the machine was extensively damaged. Although it was subsequently repaired and further trials carried out, these experiments were very expensive. Maxim eventually abandoned the flying machine and did not develop his idea for a stabilizer, turning instead to other projects. At the age of almost 70 he returned to the problems of flight and designed a biplane with a petrol engine: it was built in 1910 but never left the ground.In all, Maxim registered 122 US and 149 British patents on objects ranging from mousetraps to automatic spindles. Included among them was a 1901 patent for a foot-operated suction cleaner. In 1900 he became a British subject and he was knighted the following year. He remained a larger-than-life figure, both physically and in character, until the end of his life.[br]Principal Honours and DistinctionsChevalier de la Légion d'Honneur 1881.
