18 Giffard, Baptiste Henry Jacques (Henri)
[br]b. 8 February 1825 Paris, Franced. 14 April 1882 Paris, France[br]French pioneer of airships and balloons, inventor of an injector for steam-boiler feedwater.[br]Giffard entered the works of the Western Railway of France at the age of 16 but became absorbed by the problem of steam-powered aerial navigation. He proposed a steam-powered helicopter in 1847, but he then turned his attention to an airship. He designed a lightweight coke-burning, single-cylinder steam engine and boiler which produced just over 3 hp (2.2 kW) and mounted it below a cigar-shaped gas bag 44 m (144 ft) in length. A triangular rudder was fitted at the rear to control the direction of flight. On 24 September 1852 Giffard took off from Paris and, at a steady 8 km/h (5 mph), he travelled 28 km (17 miles) to Trappes. This can be claimed to be the first steerable lighter-than-air craft, but with a top speed of only 8 km/h (5 mph) even a modest headwind would have reduced the forward speed to nil (or even negative). Giffard built a second airship, which crashed in 1855, slightly injuring Giffard and his companion; a third airship was planned with a very large gas bag in order to lift the inherently heavy steam engine and boiler, but this was never built. His airships were inflated by coal gas and refusal by the gas company to provide further supplies brought these promising experiments to a premature end.As a draughtsman Giffard had the opportunity to travel on locomotives and he observed the inadequacies of the feed pumps then used to supply boiler feedwater. To overcome these problems he invented the injector with its series of three cones: in the first cone (convergent), steam at or below boiler pressure becomes a high-velocity jet; in the second (also convergent), it combines with feedwater to condense and impart high velocity to it; and in the third (divergent), that velocity is converted into pressure sufficient to overcome the pressure of steam in the boiler. The injector, patented by Giffard, was quickly adopted by railways everywhere, and the royalties provided him with funds to finance further experiments in aviation. These took the form of tethered hydrogen-inflated balloons of successively larger size. At the Paris Exposition of 1878 one of these balloons carried fifty-two passengers on each tethered "flight". The height of the balloon was controlled by a cable attached to a huge steam-powered winch, and by the end of the fair 1,033 ascents had been made and 35,000 passengers had seen Paris from the air. This, and similar balloons, greatly widened the public's interest in aeronautics. Sadly, after becoming blind, Giffard committed suicide; however, he died a rich man and bequeathed large sums of money to the State for humanitarian an scientific purposes.[br]Principal Honours and DistinctionsCroix de la Légion d'honneur 1863.Bibliography1860, Notice théorique et pratique sur l'injecteur automoteur.1870, Description du premier aérostat à vapeur.Further ReadingDictionnaire de biographie française.Gaston Tissandier, 1872, Les Ballons dirigeables, Paris.—1878, Le Grand ballon captif à vapeur de M.

20 Mallet, Jules Théodore Anatole
[br]b. 1837 Geneva, Switzerlandd. November 1919 Nice, France[br]Swiss engineer, inventor of the compound steam locomotive and the Mallet articulated locomotive.[br]Mallet's family moved to Normandy while he was still a child. After working as a civil engineer, in 1867 he turned to machinery, particularly to compound steam engines. He designed the first true compound steam locomotives, which were built for the Bayonne- Biarritz Railway in 1876. They were 0–4–2 tank locomotives with one high-pressure and one low-pressure cylinder. A starting valve controlled by the driver admitted high-pressure steam to the low-pressure cylinder while the high-pressure cylinder exhausted to the atmosphere. At that time it was thought impracticable in a narrow-gauge locomotive to have more than three coupled axles in rigid frames. Mallet patented his system of articulation in 1884 and the first locomotives were built to that design in 1888: they were 0–4–4–0 tanks with two sets of frames. The two rear pairs of wheels carried the rear set of frames and were driven by two high-pressure cylinders; the two front pairs, which were driven by the high-pressure cylinders, carried a separate set of frames that was allowed sideplay, with a centre of rotation between the low-pressure cylinders. In contrast to the patent locomotive of Robert Fairlie, no flexible connections were required to carry steam at boiler pressure. The first Mallet articulated locomotives were small, built to 60 cm (23.6 in.) gauge: the first standard-gauge Mallets were built in 1890, for the St Gotthard Railway, and it was only after the type was adopted by American railways in 1904 that large Mallet locomotives were built, with sizes increasing rapidly to culminate in some of the largest steam locomotives ever produced. In the late 1880s Mallet also designed monorail locomotives, which were built for the system developed by C.F.M.-T. Lartigue.[br]Bibliography1884, French patent no. 162,876 (articulated locomotive).Further ReadingJ.T.van Riemsdijk, 1970, "The compound locomotive, Part I", Transactions of the Newcomen Society 43 (describes Mallet's work on compounding).L.Wiener, 1930, Articulated Locomotives, London: Constable (describes his articulated locomotives).For the Mallet family, see Historisch-Biographisches Lexikon der Schweiz.PJGRBiographical history of technology > Mallet, Jules Théodore Anatole
