7 Priestman, William Dent
SUBJECT AREA: Steam and internal combustion engines[br]b. 23 August 1847 Sutton, Hull, Englandd. 7 September 1936 Hull, England[br]English oil engine pioneer.[br]William was the second son and one of eleven children of Samuel Priestman, who had moved to Hull after retiring as a corn miller in Kirkstall, Leeds, and who in retirement had become a director of the North Eastern Railway Company. The family were strict Quakers, so William was sent to the Quaker School in Bootham, York. He left school at the age of 17 to start an engineering apprenticeship at the Humber Iron Works, but this company failed so the apprenticeship was continued with the North Eastern Railway, Gateshead. In 1869 he joined the hydraulics department of Sir William Armstrong \& Company, Newcastle upon Tyne, but after a year there his father financed him in business at a small, run down works, the Holderness Foundry, Hull. He was soon joined by his brother, Samuel, their main business being the manufacture of dredging equipment (grabs), cranes and winches. In the late 1870s William became interested in internal combustion engines. He took a sublicence to manufacture petrol engines to the patents of Eugène Etève of Paris from the British licensees, Moll and Dando. These engines operated in a similar manner to the non-compression gas engines of Lenoir. Failure to make the two-stroke version of this engine work satisfactorily forced him to pay royalties to Crossley Bros, the British licensees of the Otto four-stroke patents.Fear of the dangers of petrol as a fuel, reflected by the associated very high insurance premiums, led William to experiment with the use of lamp oil as an engine fuel. His first of many patents was for a vaporizer. This was in 1885, well before Ackroyd Stuart. What distinguished the Priestman engine was the provision of an air pump which pressurized the fuel tank, outlets at the top and bottom of which led to a fuel atomizer injecting continuously into a vaporizing chamber heated by the exhaust gases. A spring-loaded inlet valve connected the chamber to the atmosphere, with the inlet valve proper between the chamber and the working cylinder being camoperated. A plug valve in the fuel line and a butterfly valve at the inlet to the chamber were operated, via a linkage, by the speed governor; this is believed to be the first use of this method of control. It was found that vaporization was only partly achieved, the higher fractions of the fuel condensing on the cylinder walls. A virtue was made of this as it provided vital lubrication. A starting system had to be provided, this comprising a lamp for preheating the vaporizing chamber and a hand pump for pressurizing the fuel tank.Engines of 2–10 hp (1.5–7.5 kW) were exhibited to the press in 1886; of these, a vertical engine was installed in a tram car and one of the horizontals in a motor dray. In 1888, engines were shown publicly at the Royal Agricultural Show, while in 1890 two-cylinder vertical marine engines were introduced in sizes from 2 to 10 hp (1.5–7.5 kW), and later double-acting ones up to some 60 hp (45 kW). First, clutch and gearbox reversing was used, but reversing propellers were fitted later (Priestman patent of 1892). In the same year a factory was established in Philadelphia, USA, where engines in the range 5–20 hp (3.7–15 kW) were made. Construction was radically different from that of the previous ones, the bosses of the twin flywheels acting as crank discs with the main bearings on the outside.On independent test in 1892, a Priestman engine achieved a full-load brake thermal efficiency of some 14 per cent, a very creditable figure for a compression ratio limited to under 3:1 by detonation problems. However, efficiency at low loads fell off seriously owing to the throttle governing, and the engines were heavy, complex and expensive compared with the competition.Decline in sales of dredging equipment and bad debts forced the firm into insolvency in 1895 and receivers took over. A new company was formed, the brothers being excluded. However, they were able to attend board meetings, but to exert no influence. Engine activities ceased in about 1904 after over 1,000 engines had been made. It is probable that the Quaker ethics of the brothers were out of place in a business that was becoming increasingly cut-throat. William spent the rest of his long life serving others.[br]Further ReadingC.Lyle Cummins, 1976, Internal Fire, Carnot Press.C.Lyle Cummins and J.D.Priestman, 1985, "William Dent Priestman, oil engine pioneer and inventor: his engine patents 1885–1901", Proceedings of the Institution ofMechanical Engineers 199:133.Anthony Harcombe, 1977, "Priestman's oil engine", Stationary Engine Magazine 42 (August).JBBiographical history of technology > Priestman, William Dent

8 Junkers, Hugo
SUBJECT AREA: Aerospace[br]b. 3 February 1859 Rheydt, Germanyd. 3 February 1935 Munich, Germany[br]German aircraft designer, pioneer of all-metal aircraft, including the world's first real airliner.[br]Hugo Junkers trained as an engineer and in 1895 founded the Junkers Company, which manufactured metal products including gas-powered hot-water heaters. He was also Professor of Thermodynamics at the high school in Aachen. The visits to Europe by the Wright brothers in 1908 and 1909 aroused his interest in flight, and in 1910 he was granted a patent for a flying wing, i.e. no fuselage and a thick wing which did not require external bracing wires. Using his sheet-metal experience he built the more conventional Junkers J 1 entirely of iron and steel. It made its first flight in December 1915 but was rather heavy and slow, so Junkers turned to the newly available aluminium alloys and built the J 4 bi-plane, which entered service in 1917. To stiffen the thin aluminium-alloy skins, Junkers used corrugations running fore and aft, a feature of his aircraft for the next twenty years. Incidentally, in 1917 the German authorities persuaded Junkers and Fokker to merge, but the Junkers-Fokker Company was short-lived.After the First World War Junkers very rapidly converted to commercial aviation, and in 1919 he produced a single-engined low-wing monoplane capable of carrying four passengers in an enclosed cabin. The robust all-metal F 13 is generally accepted as being the world's first airliner and over three hundred were built and used worldwide: some were still in service eighteen years later. A series of low-wing transport aircraft followed, of which the best known is the Ju 52. The original version had a single engine and first flew in 1930; a three-engined version flew in 1932 and was known as the Ju 52/3m. This was used by many airlines and served with the Luftwaffe throughout the Second World War, with almost five thousand being built.Junkers was always ready to try new ideas, such as a flap set aft of the trailing edge of the wing that became known as the "Junkers flap". In 1923 he founded a company to design and manufacture stationary diesel engines and aircraft petrol engines. Work commenced on a diesel aero-engine: this flew in 1929 and a successful range of engines followed later. Probably the most spectacular of Junkers's designs was his G 38 airliner of 1929. This was the world's largest land-plane at the time, with a wing span of 44 m (144 ft). The wing was so thick that some of the thirty-four passengers could sit in the wing and look out through windows in the leading edge. Two were built and were frequently seen on European routes.[br]Bibliography1923, "Metal aircraft construction", Journal of the Royal Aeronautical Society, London.Further ReadingG.Schmitt, 1988, Hugh Junkers and His Aircraft, Berlin.1990, Jane's Fighting Aircraft of World War I, London: Jane's (provides details of Junkers's aircraft).J.Stroud, 1966, European Transport Aircraft since 1910, London.P.

10 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.
