81 Pickard, James
SUBJECT AREA: Steam and internal combustion engines[br]fl. c. 1780 Birmingham, England[br]English patentee of the application of the crank to steam engines.[br]James Pickard, the Birmingham button maker, also owned a flour mill at Snow Hill, in 1780, where Matthew Wasborough installed one of his rotative engines with ratchet gear and a flywheel. In August 1780, Pickard obtained a patent (no. 1263) for an application to make a rotative engine with a crank as well as gearwheels, one of which was weighted to help return the piston in the atmospheric cylinder during the dead stroke and overcome the dead centres of the crank. Wasborough's flywheel made the counterweight unnecessary, and engines were built with this and Pickard's crank. Several Birmingham business people seem to have been involved in the patent, and William Chapman of Newcastle upon Tyne was assigned the sole rights of erecting engines on the Wasborough-Pickard system in the counties of Northumberland, Durham and York. Wasborough was building engines in the south until his death the following year. The patentees tried to bargain with Boulton \& Watt to exchange the use of the crank for that of the separate condenser, but Boulton \& Watt would not agree, probably because James Watt claimed that one of his workers had stolen the idea of the crank and divulged it to Pickard. To avoid infringing Pickard's patent, Watt patented his sun-and-planet motion for his rotative engines.[br]BibliographyAugust 1780, British patent no. 1,263 (rotative engine with crank and gearwheels).Further ReadingJ.Farey, 1827, A Treatise on the Steam Engine, Historical, Practical and Descriptive, reprinted 1971, Newton Abbot: David \& Charles (contains an account of Pickard's crank).

84 Bollée, Ernest-Sylvain
[br]b. 19 July 1814 Clefmont (Haute-Marne), Franced. 11 September 1891 Le Mans, France[br]French inventor of the rotor-stator wind engine and founder of the Bollée manufacturing industry.[br]Ernest-Sylvain Bollée was the founder of an extensive dynasty of bellfounders based in Le Mans and in Orléans. He and his three sons, Amédée (1844–1917), Ernest-Sylvain fils (1846–1917) and Auguste (1847-?), were involved in work and patents on steam-and petrol-driven cars, on wind engines and on hydraulic rams. The presence of the Bollées' car industry in Le Mans was a factor in the establishment of the car races that are held there.In 1868 Ernest-Sylvain Bollée père took out a patent for a wind engine, which at that time was well established in America and in England. In both these countries, variable-shuttered as well as fixed-blade wind engines were in production and patented, but the Ernest-Sylvain Bollée patent was for a type of wind engine that had not been seen before and is more akin to the water-driven turbine of the Jonval type, with its basic principle being parallel to the "rotor" and "stator". The wind drives through a fixed ring of blades on to a rotating ring that has a slightly greater number of blades. The blades of the fixed ring are curved in the opposite direction to those on the rotating blades and thus the air is directed onto the latter, causing it to rotate at a considerable speed: this is the "rotor". For greater efficiency a cuff of sheet iron can be attached to the "stator", giving a tunnel effect and driving more air at the "rotor". The head of this wind engine is turned to the wind by means of a wind-driven vane mounted in front of the blades. The wind vane adjusts the wind angle to enable the wind engine to run at a constant speed.The fact that this wind engine was invented by the owner of a brass foundry, with all the gear trains between the wind vane and the head of the tower being of the highest-quality brass and, therefore, small in scale, lay behind its success. Also, it was of prefabricated construction, so that fixed lengths of cast-iron pillar were delivered, complete with twelve treads of cast-iron staircase fixed to the outside and wrought-iron stays. The drive from the wind engine was taken down the inside of the pillar to pumps at ground level.Whilst the wind engines were being built for wealthy owners or communes, the work of the foundry continued. The three sons joined the family firm as partners and produced several steam-driven vehicles. These vehicles were the work of Amédée père and were l'Obéissante (1873); the Autobus (1880–3), of which some were built in Berlin under licence; the tram Bollée-Dalifol (1876); and the private car La Mancelle (1878). Another important line, in parallel with the pumping mechanism required for the wind engines, was the development of hydraulic rams, following the Montgolfier patent. In accordance with French practice, the firm was split three ways when Ernest-Sylvain Bollée père died. Amédée père inherited the car side of the business, but it is due to Amédée fils (1867– 1926) that the principal developments in car manufacture came into being. He developed the petrol-driven car after the impetus given by his grandfather, his father and his uncle Ernest-Sylvain fils. In 1887 he designed a four-stroke single-cylinder engine, although he also used engines designed by others such as Peugeot. He produced two luxurious saloon cars before putting Torpilleur on the road in 1898; this car competed in the Tour de France in 1899. Whilst designing other cars, Amédée's son Léon (1870–1913) developed the Voiturette, in 1896, and then began general manufacture of small cars on factory lines. The firm ceased work after a merger with the English firm of Morris in 1926. Auguste inherited the Eolienne or wind-engine side of the business; however, attracted to the artistic life, he sold out to Ernest Lebert in 1898 and settled in the Paris of the Impressionists. Lebert developed the wind-engine business and retained the basic "stator-rotor" form with a conventional lattice tower. He remained in Le Mans, carrying on the business of the manufacture of wind engines, pumps and hydraulic machinery, describing himself as a "Civil Engineer".The hydraulic-ram business fell to Ernest-Sylvain fils and continued to thrive from a solid base of design and production. The foundry in Le Mans is still there but, more importantly, the bell foundry of Dominique Bollée in Saint-Jean-de-Braye in Orléans is still at work casting bells in the old way.[br]Further ReadingAndré Gaucheron and J.Kenneth Major, 1985, The Eolienne Bollée, The International Molinological Society.Cénomane (Le Mans), 11, 12 and 13 (1983 and 1984).KM -
85 Brayton, George Bailey
SUBJECT AREA: Steam and internal combustion engines[br]b. 1839 Rhode Island, USAd. 1892 Leeds, England[br]American engineer, inventor of gas and oil engines.[br]During the thirty years prior to his death, Brayton devoted considerable effort to the development of internal-combustion engines. He designed the first commercial gas engine of American origin in 1872. An oil-burning engine was produced in 1875. An aptitude for mechanical innovation became apparent whilst he was employed at the Exeter Machine Works, New Hampshire, where he developed a successful steam generator for use in domestic and industrial heating systems. Brayton engines were distinguished by the method of combustion. A pressurized air-fuel mixture from a reservoir was ignited as it entered the working cylinder—a precursor of the constant-pressure cycle. A further feature of these early engines was a rocking beam. There exist accounts of Brayton engines fitted into river craft, and of one in a carriage which operated for a few months in 1872–3. However, the appearance of the four-stroke Otto engine in 1876, together with technical problems associated with backfiring into the fuel reservoir, prevented large-scale acceptance of the Brayton engine. Although Thompson Sterne \& Co. of Glasgow became licensees, the engine failed to gain usage in Britain. A working model of Brayton's gas engine is exhibited in the Museum of History and Technology in Washington, DC.[br]Bibliography1872, US patent no. 125,166 (Brayton gas engine).July 1890, British patent no. 11,062 (oil engine; under patent agent W.R.Lake).Further ReadingD.Clerk, 1895, The Gas and Oil Engine, 6th edn, London, pp. 152–62 (includes a description and report of tests carried out on a Brayton engine).KAB -
86 Brown, Samuel
SUBJECT AREA: Steam and internal combustion engines[br]b. unknownd. 1849 England[br]English cooper, inventor of a gas vacuum engine.[br]Between the years 1823 and 1833, Brown achieved a number of a firsts as a pioneer of internal-combustion engines. In 1824 he built a full-scale working model of a pumping engine; in 1826, a vehicle fitted with a gas vacuum engine ascended Shooters Hill in Kent; and in 1827 he conducted trials of a motor-driven boat on the Thames that were witnessed by Lords of the Admiralty. The principle of Brown's engine had been demonstrated by Cecil in 1820. A burning gas flame was extinguished within a closed cylinder, creating a partial vacuum; atmospheric pressure was then utilized to produce the working stroke. By 1832 a number of Brown's engines in use for pumping water were reported, the most notable being at Croydon Canal. However, high fuel consumption and running costs prevented a wide acceptance of Brown's engines, and a company formed in 1825 was dissolved only two years later. Brown continued alone with his work until his death.[br]Bibliography1823, British patent no. 4,874 (gas vacuum engine).1826, British patent no. 5,350 (improved gas vacuum engine).1846, British patent no. 11,076, "Improvements in Gas Engines and in Propelling Carriages and Vessels" (no specification was enrolled).Further ReadingVarious discussions of Brown's engines can be found in Mechanics Magazine (1824) 2:360, 385; (1825) 3:6; (1825) 4:19, 309; (1826) 5:145; (1826) 6:79; (1827) 7:82–134; (1832) 17:273.The Engineer 182:214.A.K.Bruce, Samuel Brown and the Gas Engine.Dugald Clerk, 1895, The Gas and Oil Engine, 6th edn, London, pp. 2–3.KAB -
87 Wasborough, Matthew
SUBJECT AREA: Steam and internal combustion engines[br]b. 1753 Bristol, Englandd. 21 October 1781 Bristol, England[br]English patentee of an application of the flywheel to create a rotative steam engine.[br]A single-cylinder atmospheric steam engine had a power stroke only when the piston descended the cylinder: a means had to be found of returning the piston to its starting position. For rotative engines, this was partially solved by the patent of Matthew Wasborough in 1779. His father was a partner in a Bristol brass-founding and clockmaking business in Narrow Wine Street where he was joined by his son. Wasborough proposed to use some form of ratchet gear to effect the rotary motion and added a flywheel, the first time one was used in a steam engine, "in order to render the motion more regular and uniform". He installed one engine to drive the lathes in the Bristol works and another at James Pickard's flour mill at Snow Hill, Birmingham, where Pickard applied his recently patented crank to it. It was this Wasborough-Pickard engine which posed a threat to Boulton \& Watt trying to develop a rotative engine, for Wasborough built several engines for cornmills in Bristol, woollen mills in Gloucestershire and a block factory at Southampton before his early death. Matthew Boulton was told that Wasborough was "so intent upon the study of engines as to bring a fever on his brain and he dyed in consequence thereof…. How dangerous it is for a man to wade out of his depth" (Jenkins 1936:106).[br]Bibliography1779, British patent no. 1,213 (rotative engine with flywheel).Further ReadingJ.Tann, 1978–9, "Makers of improved Newcomen engines in the late 18th century, and R.A.Buchanan", 1978–9, "Steam and the engineering community in the eighteenth century", Transactions of the Newcomen Society 50 ("Thomas Newcomen.

SUBJECT AREA: Metallurgy, Railways and locomotives, Steam and internal combustion engines, Telecommunications[br]b. 1822 Mussey-la-Ville, Belgiumd. 1900 Verenna Saint-Hildar, France[br]Belgian (naturalized French in 1870) inventor of internal combustion engines, an electroplating process and railway telegraphy systems.[br]Leaving his native village for Paris at the age of 16, Lenoir became a metal enameller. Experiments with various electroplating processes provided a useful knowledge of electricity that showed in many of his later ideas. Electric ignition, although somewhat unreliable, was a feature of the Lenoir gas engine which appeared in 1860. Resembling the steam engine of the day, Lenoir engines used a non-compression cycle of operations, in which the gas-air mixture of about atmospheric pressure was being ignited at one-third of the induction stroke. The engines were double acting. About five hundred of Lenoir's engines were built, mostly in Paris by M.Hippolyte Marinoni and by Lefébvre; the Reading Ironworks in England built about one hundred. Many useful applications of the engine are recorded, but the explosive shock that occurred on ignition, together with the unreliable ignition systems, prevented large-scale acceptance of the engine in industry. However, Lenoir's effort and achievements stimulated much discussion, and N.A. Otto is reported to have carried out his first experiments on a Lenoir engine.[br]Principal Honours and DistinctionsAcadémie des Sciences Prix Montyon Prize 1870.

In 1851, during a landreclamation project in Florence, he became acquainted with Eugenio Barsanti. Together they succeeded in designing and producing a number of the first type of gas engines to produce a vacuum within a closed cylinder, atmospheric pressure then being utilized to produce the power stroke. The principle was demonstrated by Cecil in 1820 and was used by Samuel Brown in 1827 and by N.A. Otto in 1867. The company Società Promotrice del Nuovo Motore Barsanti e Matteucci was formed in 1860, but ill health forced Matteucci to resign in 1862, and in 1864 Barsanti, whilst negotiating mass production of engines with Cockerill of Seraing, Belgium, contracted typhoid and later died. Efforts to continue the business in Italy subsequently failed and Matteucci returned to his engineering practice.[br]Bibliography13 May 1852, British Provisional Patent no. 1,072 (the Barsanti and Matteucci engine). 12 June 1857, British patent no. 1,655 (contained many notable improvements to the design).Further ReadingThe Engineer (1858) 5:73–4 (for an account of the Italian engine).Vincenzo Vannacci, 1955, L'invenzione del motore a scoppio realizzota dai toscani Barsanti e Matteucci 1854–1954, Florence.KAB -

92 Beau de Rochas, Alphonse Eugène
SUBJECT AREA: Steam and internal combustion engines[br]b. 1815 Franced. 1893 France[br]French railway engineer, patentee of a four-stroke cycle engine.[br]Renowned more for his ideas on technical matters than his practical deeds, Beau de Rochas was a prolific thinker. Within a few years he proposed a rail tunnel beneath the English Channel, a submarine telegraph, a new kind of drive for canal boats, the use of steel for high-pressure boilers and a method of improving the adhesion of locomotive wheels travelling the Alps.The most notable of Beau de Rochas's ideas occurred in 1862 when he was employed as Ingenieur Attaché to the Central de Chemins. With remarkable foresight, he expressed the theoretical considerations for the cycle of operations for the now widely used four-stroke cycle engine. A French patent of 1862 lapsed with a failure to pay the annuity and thus the proposals for a new motive power lapsed into obscurity. Resurrected some twenty years later, the Beau de Rochas tract figures prominently in patent litigation cases. In 1885, a German court upheld a submission by a German patent lawyer that Otto's four-stroke engine of 1876 infringed the Beau de Rochas patent. It remains a mystery why Beau de Rochas never emerged at any time to defend his claims. In France he is regarded as the inventor of the four-stroke cycle engine.[br]Principal Honours and DistinctionsSociété d'Encouragement pour l'Industrie Nationale, prize of 3000 francs, 1891.Bibliography1885, The Engineer 60:441 (an English translation of the Beau de Rochas tract).Further Reading1938, Bulletin de la Société d'Encouragement pour l'Industrie Nationale 137:209–39. 1962, Document pour l'histoire des techniques Cahier no. 2: pp. 3–42.B.Donkin, 1900, The Gas, Oil and Air Engine, London: p. 467.See also: Langen, EugenKABBiographical history of technology > Beau de Rochas, Alphonse Eugène

94 Barsanti, Eugenio
SUBJECT AREA: Steam and internal combustion engines[br]b. 1821 Italyd. 1864 Liège, Belgium[br]Italian co-inventor of the internal combustion engine; lecturer in mechanics and hydraulics.[br]A trained scientist and engineer, Barsanti became acquainted with a distinguished engineer, Felice Matteucci, in 1851. Their combined talents enabled them to produce a number of so-called free-piston atmospheric engines from 1854 onwards. Using a principle demonstrated by the Swiss engineer Isaac de Rivaz in 1827, the troublesome explosive shocks encountered by other pioneers were avoided. A piston attached to a long toothed rack was propelled from beneath by the expansion of burning gas and allowed unrestricted movement. A resulting partial vacuum enabled atmospheric pressure to return the piston and produce the working stroke. Electric ignition was a feature of all the Italian engines.With many successful applications, a company was formed in 1860. A 20 hp (15 kW) engine stimulated much interest. Attempts by John Cockerill of Belgium to mass-produce small power units of up to 4 hp (3 kW) came to an abrupt end; during the negotiations Barsanti contracted typhoid fever and later died. The project was abandoned, but the working principle of the Italian engine was used successfully in the Otto-Langen engine of 1867.[br]Bibliography13 May 1854, British Provisional Patent no. 1,072 (the Barsanti and Matteucci engine).12 June 1857, British patent no. 1,655 (contained many notable improvements to the design).Further ReadingThe Engineer (1858) 5:73–4 (for an account of the Italian engine).Vincenzo Vannacci, 1955, L'invenzione del motore a scoppio realizzota dai toscani Barsanti e Matteucci 1854–1954, Florence.KAB -

SUBJECT AREA: Steam and internal combustion engines[br]fl. 1885 London, England[br]English (?) patentee of steam engines incorporating the uniflow principle.[br]In a uniflow system, the steam enters a steam engine cylinder at one end, pushes the pistons along, and exhausts through a ring of ports at the centre of the cylinder that are uncovered by movement of the piston. The piston is returned by steam then entering the other end of the cylinder, moving the piston arrangement back, and again making its exit through the central ports. This gave the thermodynamic advantage of the cylinder ends remaining hot and the centre colder with reheating the ends of the cylinder through compression of the residual steam. The principle was first patented by Jacob Perkins in England in 1827 and was tried in America in 1856.Little is known about Todd. The addresses given in his patent specifications show that he was living first at South Hornsey and then Stoke Newington, both in Middlesex (now in London). No obituary notices have been traced. He took out a patent in 1885 for a "terminal exhaust engine" and followed this with two more in 1886 and 1887. His aim was to "produce a double acting steam engine which shall work more efficiently, which shall produce and maintain within itself an improved gradation of temperature extending from each of its two Hot Inlets to its common central Cold Outlet". His later patents show the problems he faced with finding suitable valve gears and the compression developing during the return stroke of the piston. It was this last problem, particularly when starting a condensing engine, that probably defeated him through excessive compression pressures. There is some evidence that he hoped to apply his engines to railway locomotives.[br]Bibliography1885, British patent no. 7,301 (terminal exhaust engine). 1886, British patent no. 2,132.1887, British patent no. 6,666.Further ReadingR.L.Hills, 1989, Power from Steam.

98 Benz, Karl
[br]b. 25 November 1844 Pfaffenrot, Black Forest, Germanyd. 4 April 1929 Ladenburg, near Mannheim, Germany[br]German inventor of one of the first motor cars.[br]The son of a railway mechanic, it is said that as a child one of his hobbies was the repair of Black Forest clocks. He trained as a mechanical engineer at the Karlsruhe Lyzeum and Polytechnikum under Ferdinand Redtenbacher (d. 1863), who pointed out to him the need for a more portable power source than the steam engine. He went to Maschinenbau Gesellschaft Karlsruhe for workshop experience and then joined Schweizer \& Cie, Mannheim, for two years. In 1868 he went to the Benkiser Brothers at Pforzheim. In 1871 he set up a small machine-tool works at Mannheim, but in 1877, in financial difficulties, he turned to the idea of an entirely new product based on the internal-combustion engine. At this time, N.A. Otto held the patent for the four-stroke internal-combustion engine, so Benz had to put his hopes on a two-stroke design. He avoided the trouble with Dugald Clerk's engine and designed one in which the fuel would not ignite in the pump and in which the cylinder was swept with fresh air between each two firing strokes. His first car had a sparking plug and coil ignition. By 1879 he had developed the engine to a stage where it would run satisfactorily with little attention. On 31 December 1879, with his wife Bertha working the treadle of her sewing machine to charge the batteries, he demonstrated his engine in street trials in Mannheim. In the summer of 1888, unknown to her husband, Bertha drove one of his cars the 80 km (50 miles) to Pforzheim and back with her two sons, aged 13 and 15. She and the elder boy pushed the car up hills while the younger one steered. They bought petrol from an apothecary in Wiesloch and had a brake block repaired in Bauschlott by the village cobbler. Karl Benz's comments on her return from this venture are not recorded! Financial problems prevented immediate commercial production of the automobile, but in 1882 Benz set up the Gasmotorenfabrik Mannheim. After trouble with some of his partners, he left in 1883 and formed a new company, Benz \& Cie, Rheinische Gasmotorenfabrik. Otto's patent was revoked in 1886 and in that year Benz patented a motor car with a gas engine drive. He manufactured a 0.8hp car, the engine running at 250 rpm with a horizontal flywheel, exhibited at the Paris Fair in 1889. He was not successful in finding anyone in France who would undertake manufacture. This first car was a three-wheeler, and soon after he produced a four-wheeled car, but he quarrelled with his co-directors, and although he left the board in 1902 he rejoined it soon after.[br]Further ReadingSt J.Nixon, 1936, The Invention of the Automobile.

99 Langen, Eugen
[br]b. 1839 Germanyd. 1895 Germany[br]German engineer and businessmen.[br]A sound engineering training combined with an inherited business sense were credentials that Langen put to good use in his association with internal-combustion engines. The sight of a working engine built by N.A. Otto in 1864 convinced Langen that this was a means to provide power in industry. Shortly afterwards, assisted by members of his family, he formed the company N.A.Otto and Cie, Cologne, the world's first engine factory. At the Paris Exhibition of 1867, the new Otto-Langen Atmospheric Gas Engine was awarded a Gold Medal, and in 1870 Crossley Bros of Manchester was appointed sole agent and manufacturer in Britain. Under Langen's guidance, the firm grew, and in 1872 it was renamed Die Gasmotoren Fabrik, employing Gottlieb Daimler and Wilhelm Maybach. Apart from running the business, Langen often played peacemaker when differences arose between Daimler and Otto. The success of the firm, known today as Klockner-Humboldt-Deutz, owed much to Langen's business and technical skills. Langen was a strong supporter of Otto's constant efforts to produce a better engine, and his confidence was justified by the appearance, in 1876, of Otto's four-stroke engine. The two men remained close friends until Otto's death in 1892.[br]Further ReadingFriederick Sass, 1962, Geschichte des deutschen Verbrennungsmotorenbaues von 1860 bis 1918, Berlin: Springen Verlag (a detailed account).Gustav Goldbeck, 1964, Kraft für die Welt: 100 Jahre Klockner-Humboldt-Deutz AG, Dusseldorf (an account of the history and development of Klockner Humboldt).KAB -
