61 Belling, Charles Reginald
SUBJECT AREA: Domestic appliances and interiors[br]b. 11 May 1884 Bodmin, Cornwall, Englandd. 8 February 1965 while on a cruise[br]English electrical engineer best known as the pioneer of the wire-wound clay-former heating element which made possible the efficient domestic electric fire.[br]Belling was educated at Burts Grammar School in Lostwithiel, Cornwall, and at Crossley Schools in Halifax, Yorkshire. In 1903 he was apprenticed to Crompton \& Co. at Chelmsford in Essex, the firm that in 1894 offered for sale the earliest electric heaters. These electric radiant panels were intended as heating radiators or cooking hotplates, but were not very successful because, being cast-iron panels into which heating wires had been embedded in enamel, they tended to fracture due to the different rates of thermal expansion of the iron and the enamel. Other designs of electric heaters followed, notably the introduction of large, sausage-shaped carbon filament bulbs fitted into a fire frame and backed by reflectors. This was the idea of H. Dowsing, a collaborator of Crompton, in 1904.After qualifying in 1906, Belling left Crompton \& Co. and went to work for Ediswan at Ponders End in Hertfordshire. He left in 1912 to set up his own business, which he began in a small shed in Enfield. With a small staff and capital of £450, he took out his first patent for his wire-wound-former electric fire in the same year. The resistance wire, made from nickel-chrome alloy such as that patented in 1906 by A.L. Marsh, was coiled round a clay former. Six such bars were attached to a cast-iron frame with heating control knobs, and the device was marketed as the Standard Belling Fire. Advertised in 1912, the fire was an immediate success and was followed by many other variations. Improvements to the first model included wire safety guards, enamel finishes and a frame ornamented with copper and brass.Belling turned his attention to hotplates, cookers, immersion heaters, electric irons, water urns and kettles, producing the Modernette Cooker (1919), the multi-parabola fire bar (1921), the plate and dish warmer (1924), the storage heater (1926) and the famous Baby Belling cookers, the first of which appeared in 1929. By 1955 business had developed so well that Belling opened another factory at Burnley, Lancashire. He partly underwrote, for the amount of £1 million, a proposed scientific technical college for the electrical industry at Enfield.[br]Further Reading1985, Dictionary of Business Biography, Butterworth.G.Jukes, 1963, The Story of Belling, Belling and Co.

62 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.
