  • 6 Bollée, Ernest-Sylvain

    [br]
    b. 19 July 1814 Clefmont (Haute-Marne), France
    d. 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.

  • 7 Priestman, William Dent

    [br]
    b. 23 August 1847 Sutton, Hull, England
    d. 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.

  • 8 Babbage, Charles

    [br]
    b. 26 December 1791 Walworth, Surrey, England
    d. 18 October 1871 London, England
    [br]
    English mathematician who invented the forerunner of the modern computer.
    [br]
    Charles Babbage was the son of a banker, Benjamin Babbage, and was a sickly child who had a rather haphazard education at private schools near Exeter and later at Enfield. Even as a child, he was inordinately fond of algebra, which he taught himself. He was conversant with several advanced mathematical texts, so by the time he entered Trinity College, Cambridge, in 1811, he was ahead of his tutors. In his third year he moved to Peterhouse, whence he graduated in 1814, taking his MA in 1817. He first contributed to the Philosophical Transactions of the Royal Society in 1815, and was elected a fellow of that body in 1816. He was one of the founders of the Astronomical Society in 1820 and served in high office in it.
    While he was still at Cambridge, in 1812, he had the first idea of calculating numerical tables by machinery. This was his first difference engine, which worked on the principle of repeatedly adding a common difference. He built a small model of an engine working on this principle between 1820 and 1822, and in July of the latter year he read an enthusiastically received note about it to the Astronomical Society. The following year he was awarded the Society's first gold medal. He submitted details of his invention to Sir Humphry Davy, President of the Royal Society; the Society reported favourably and the Government became interested, and following a meeting with the Chancellor of the Exchequer Babbage was awarded a grant of £1,500. Work proceeded and was carried on for four years under the direction of Joseph Clement.
    In 1827 Babbage went abroad for a year on medical advice. There he studied foreign workshops and factories, and in 1832 he published his observations in On the Economy of Machinery and Manufactures. While abroad, he received the news that he had been appointed Lucasian Professor of Mathematics at Cambridge University. He held the Chair until 1839, although he neither resided in College nor gave any lectures. For this he was paid between £80 and £90 a year! Differences arose between Babbage and Clement. Manufacture was moved from Clement's works in Lambeth, London, to new, fireproof buildings specially erected by the Government near Babbage's house in Dorset Square, London. Clement made a large claim for compensation and, when it was refused, withdrew his workers as well as all the special tools he had made up for the job. No work was possible for the next fifteen months, during which Babbage conceived the idea of his "analytical engine". He approached the Government with this, but it was not until eight years later, in 1842, that he received the reply that the expense was considered too great for further backing and that the Government was abandoning the project. This was in spite of the demonstration and perfectly satisfactory operation of a small section of the analytical engine at the International Exhibition of 1862. It is said that the demands made on manufacture in the production of his engines had an appreciable influence in improving the standard of machine tools, whilst similar benefits accrued from his development of a system of notation for the movements of machine elements. His opposition to street organ-grinders was a notable eccentricity; he estimated that a quarter of his mental effort was wasted by the effect of noise on his concentration.

    [br]
    b. 17 March 1834 Schorndorff, near Stuttgart, Germany
    d. 6 March 1900 Cannstatt, near Stuttgart, Germany
    [br]
    German engineer, pioneer automobile maker.
    [br]
    The son of a baker, his youthful interest in technical affairs led to his being apprenticed to a gunsmith with whom he produced his apprenticeship piece: a double-barrelled pistol with a rifled barrel and "nicely chased scrollwork", for which he received high praise. He remained there until 1852 before going to technical school in Stuttgart from 1853 to 1857. He then went to a steam-engineering company in Strasbourg to gain practical experience. He completed his formal education at Stuttgart Polytechnik, and in 1861 he left to tour France and England. There he worked in the engine-shop of Smith, Peacock \& Tanner and then with Roberts \& Co., textile machinery manufacturers of Manchester. He later moved to Coventry to work at Whitworths, and it was in that city that he was later involved with the Daimler Motor Company, who had been granted a licence by his company in Germany. In 1867 he was working at Bruderhaus Engineering Works at Reutlingen and in 1869 went to Maschinenbau Gesellschaft Karlsruhe where he became Manager and later a director. Early in the 1870s, N.A. Otto had reorganized his company into Gasmotorenfabrik Deutz and he appointed Gottlieb Daimler as Factory Manager and Wilhelm Maybach as Chief Designer. Together they developed the Otto engine to its limit, with Otto's co-operation. Daimler and Maybach had met previously when both were working at Bruderhaus. In 1875 Daimler left Deutz, taking Maybach with him to set up a factory in Stuttgart to manufacture light, high-speed internal-combustion engines. Their first patent was granted in 1883. This was for an engine fuelled by petrol and with hot tube ignition which continued to be used until Robert Bosch's low-voltage ignition became available in 1897. Two years later he produced his first vehicle, a motor cycle with outriggers. They showed a motor car at the Paris exhibition in 1889, but French manufacturers were slow to come forward and no French company could be found to undertake manufacture. Eventually Panhard and Levassor established the Daimler engine in France. Daimler Motoren GmbH was started in 1895, but soon after Daimler and Maybach parted, having provided an engine for a boat on the River Neckar in 1887 and that for the Wolfert airship in 1888. Daimler was in sole charge of the company from 1895, but his health began to decline in 1899 and he died in 1900.

    French pioneer in automobile manufacture.
    [br]
    Bouton was the son of a painter and learned mechanics at Honfleur and Paris. In 1870 he was fighting in Les Mobiles de Calvados, and in 1881, having finished his training, he joined his brother-in-law, Trepardoux, to open a workshop in rue de la Chapelle for the construction of steam engines for scientific toys. The comte de Dion discovered the workshop and became associated with it in 1882. They also built steam-boilers for automobiles. In 1883 they built their first quadricycle, and in 1887 their first steam tricycle. These were followed in 1892 and 1893 by a car and a steam tractor. After the appearance of the petrol engine they put in hand a star-shaped four-cylinder engine of this type, but it was not until 1895 and 1898 that the first de Dion-Bouton single-cylinder tricycle and their petrol bicycle, respectively, came out. From 1899 the manufacture of de Dion-Bouton was concentrated on the voiturette. Georges Bouton was responsible for the manufacture of all these machines and took part in the first motor races.

  • 12 Stuart, Herbert Akroyd

    [br]
    b. 1864 Halifax, England
    d. 1927 Perth, Australia
    [br]
    English inventor of an oil internal-combustion engine.
    [br]
    Stuart's involvement with engines covered a period of less than ten years and was concerned with a means of vaporizing the heavier oils for use in the so-called oil engines. Leaving his native Yorkshire for Bletchley in Buckinghamshire, Stuart worked in his father's business, the Bletchley Iron and Tin Plate works. After finishing grammar school, he worked as an assistant in the Mechanical Engineering Department of the City and Guilds of London Technical College. He also formed a connection with the Finsbury Technical College, where he became acquainted with Professor William Robinson, a distinguished engineer eminent in the field of internal-combustion engines.
    Resuming work at Bletchley, Stuart carried out experiments with engines. His first patent was concerned with new methods of vaporizing the fuel, scavenging systems and improvement of speed control. Two further patents, in 1890, specified substantial improvements and formed the basis of later engine designs. In 1891 Stuart joined forces with R.Hornsby and Sons of Grantham, a firm founded in 1815 for the manufacture of machinery and steam engines. Hornsby acquired all rights to Stuart's engine patents, and their superior technical resources ensured substantial improvements to Stuart's early design. The Hornsby-Ackroyd engines, introduced in 1892, were highly successful and found wide acceptance, particularly in agriculture. With failing health, Stuart's interest in his engine work declined, and in 1899 he emigrated to Australia, where in 1903 he became a partner in importing gas engines and gas-producing plants. Following his death in 1927, under the terms of his will he was interred in England; sadly, he also requested that all papers and materials pertaining to his engines be destroyed.

    [br]
    b. 25 November 1844 Pfaffenrot, Black Forest, Germany
    d. 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.

  • 14 Trevithick, Richard

    [br]
    b. 13 April 1771 Illogan, Cornwall, England
    d. 22 April 1833 Dartford, Kent, England
    [br]
    English engineer, pioneer of non-condensing steam-engines; designed and built the first locomotives.
    [br]
    Trevithick's father was a tin-mine manager, and Trevithick himself, after limited formal education, developed his immense engineering talent among local mining machinery and steam-engines and found employment as a mining engineer. Tall, strong and high-spirited, he was the eternal optimist.
    About 1797 it occurred to him that the separate condenser patent of James Watt could be avoided by employing "strong steam", that is steam at pressures substantially greater than atmospheric, to drive steam-engines: after use, steam could be exhausted to the atmosphere and the condenser eliminated. His first winding engine on this principle came into use in 1799, and subsequently such engines were widely used. To produce high-pressure steam, a stronger boiler was needed than the boilers then in use, in which the pressure vessel was mounted upon masonry above the fire: Trevithick designed the cylindrical boiler, with furnace tube within, from which the Cornish and later the Lancashire boilers evolved.
    Simultaneously he realized that high-pressure steam enabled a compact steam-engine/boiler unit to be built: typically, the Trevithick engine comprised a cylindrical boiler with return firetube, and a cylinder recessed into the boiler. No beam intervened between connecting rod and crank. A master patent was taken out.
    Such an engine was well suited to driving vehicles. Trevithick built his first steam-carriage in 1801, but after a few days' use it overturned on a rough Cornish road and was damaged beyond repair by fire. Nevertheless, it had been the first self-propelled vehicle successfully to carry passengers. His second steam-carriage was driven about the streets of London in 1803, even more successfully; however, it aroused no commercial interest. Meanwhile the Coalbrookdale Company had started to build a locomotive incorporating a Trevithick engine for its tramroads, though little is known of the outcome; however, Samuel Homfray's ironworks at Penydarren, South Wales, was already building engines to Trevithick's design, and in 1804 Trevithick built one there as a locomotive for the Penydarren Tramroad. In this, and in the London steam-carriage, exhaust steam was turned up the chimney to draw the fire. On 21 February the locomotive hauled five wagons with 10 tons of iron and seventy men for 9 miles (14 km): it was the first successful railway locomotive.
    Again, there was no commercial interest, although Trevithick now had nearly fifty stationary engines completed or being built to his design under licence. He experimented with one to power a barge on the Severn and used one to power a dredger on the Thames. He became Engineer to a project to drive a tunnel beneath the Thames at Rotherhithe and was only narrowly defeated, by quicksands. Trevithick then set up, in 1808, a circular tramroad track in London and upon it demonstrated to the admission-fee-paying public the locomotive Catch me who can, built to his design by John Hazledine and J.U. Rastrick.
    In 1809, by which date Trevithick had sold all his interest in the steam-engine patent, he and Robert Dickinson, in partnership, obtained a patent for iron tanks to hold liquid cargo in ships, replacing the wooden casks then used, and started to manufacture them. In 1810, however, he was taken seriously ill with typhus for six months and had to return to Cornwall, and early in 1811 the partners were bankrupt; Trevithick was discharged from bankruptcy only in 1814.
    In the meantime he continued as a steam engineer and produced a single-acting steam engine in which the cut-off could be varied to work the engine expansively by way of a three-way cock actuated by a cam. Then, in 1813, Trevithick was approached by a representative of a company set up to drain the rich but flooded silver-mines at Cerro de Pasco, Peru, at an altitude of 14,000 ft (4,300 m). Low-pressure steam engines, dependent largely upon atmospheric pressure, would not work at such an altitude, but Trevithick's high-pressure engines would. Nine engines and much other mining plant were built by Hazledine and Rastrick and despatched to Peru in 1814, and Trevithick himself followed two years later. However, the war of independence was taking place in Peru, then a Spanish colony, and no sooner had Trevithick, after immense difficulties, put everything in order at the mines then rebels arrived and broke up the machinery, for they saw the mines as a source of supply for the Spanish forces. It was only after innumerable further adventures, during which he encountered and was assisted financially by Robert Stephenson, that Trevithick eventually arrived home in Cornwall in 1827, penniless.
    He petitioned Parliament for a grant in recognition of his improvements to steam-engines and boilers, without success. He was as inventive as ever though: he proposed a hydraulic power transmission system; he was consulted over steam engines for land drainage in Holland; and he suggested a 1,000 ft (305 m) high tower of gilded cast iron to commemorate the Reform Act of 1832. While working on steam propulsion of ships in 1833, he caught pneumonia, from which he died.

  • 16 Ricardo, Sir Harry Ralph

    [br]
    b. 26 January 1885 London, England
    d. 18 May 1974 Graffham, Sussex, England
    [br]
    English mechanical engineer; researcher, designer and developer of internal combustion engines.
    [br]
    Harry Ricardo was the eldest child and only son of Halsey Ricardo (architect) and Catherine Rendel (daughter of Alexander Rendel, senior partner in the firm of consulting civil engineers that later became Rendel, Palmer and Tritton). He was educated at Rugby School and at Cambridge. While still at school, he designed and made a steam engine to drive his bicycle, and by the time he went up to Cambridge in 1903 he was a skilled craftsman. At Cambridge, he made a motor cycle powered by a petrol engine of his own design, and with this he won a fuel-consumption competition by covering almost 40 miles (64 km) on a quart (1.14 1) of petrol. This brought him to the attention of Professor Bertram Hopkinson, who invited him to help with research on turbulence and pre-ignition in internal combustion engines. After leaving Cambridge in 1907, he joined his grandfather's firm and became head of the design department for mechanical equipment used in civil engineering. In 1916 he was asked to help with the problem of loading tanks on to railway trucks. He was then given the task of designing and organizing the manufacture of engines for tanks, and the success of this enterprise encouraged him to set up his own establishment at Shoreham, devoted to research on, and design and development of, internal combustion engines.
    Leading on from the work with Hopkinson were his discoveries on the suppression of detonation in spark-ignition engines. He noted that the current paraffinic fuels were more prone to detonation than the aromatics, which were being discarded as they did not comply with the existing specifications because of their high specific gravity. He introduced the concepts of "highest useful compression ratio" (HUCR) and "toluene number" for fuel samples burned in a special variable compression-ratio engine. The toluene number was the proportion of toluene in heptane that gave the same HUCR as the fuel sample. Later, toluene was superseded by iso-octane to give the now familiar octane rating. He went on to improve the combustion in side-valve engines by increasing turbulence, shortening the flame path and minimizing the clearance between piston and head by concentrating the combustion space over the valves. By these means, the compression ratio could be increased to that used by overhead-valve engines before detonation intervened. The very hot poppet valve restricted the advancement of all internal combustion engines, so he turned his attention to eliminating it by use of the single sleeve-valve, this being developed with support from the Air Ministry. By the end of the Second World War some 130,000 such aero-engines had been built by Bristol, Napier and Rolls-Royce before the piston aero-engine was superseded by the gas turbine of Whittle. He even contributed to the success of the latter by developing a fuel control system for it.
    Concurrent with this was work on the diesel engine. He designed and developed the engine that halved the fuel consumption of London buses. He invented and perfected the "Comet" series of combustion chambers for diesel engines, and the Company was consulted by the vast majority of international internal combustion engine manufacturers. He published and lectured widely and fully deserved his many honours; he was elected FRS in 1929, was President of the Institution of Mechanical Engineers in 1944–5 and was knighted in 1948. This shy and modest, though very determined man was highly regarded by all who came into contact with him. It was said that research into internal combustion engines, his family and boats constituted all that he would wish from life.

  • 18 Brown, Joseph Rogers

    [br]
    b. 26 January 1810 Warren, Rhode Island, USA
    d. 23 July 1876 Isles of Shoals, New Hampshire, USA
    [br]
    American machine-tool builder and co-founder of Brown \& Sharpe.
    [br]
    Joseph Rogers Brown was the eldest son of David Brown, who was modestly established as a maker of and dealer in clocks and watches. Joseph assisted his father during school vacations and at the age of 17 left to obtain training as a machinist. In 1829 he joined his father in the manufacture of tower clocks at Pawtucket, Rhode Island, and two years later went into business for himself in Pawtucket making lathes and small tools. In 1833 he rejoined his father in Providence, Rhode Island, as a partner in the manufacture of docks, watches and surveying and mathematical instruments. David Brown retired in 1841.
    J.R.Brown invented and built in 1850 a linear dividing engine which was the first automatic machine for graduating rules in the United States. In 1851 he brought out the vernier calliper, the first application of a vernier scale in a workshop measuring tool. Lucian Sharpe was taken into partnership in 1853 and the firm became J.R.Brown \& Sharpe; in 1868 the firm was incorporated as the Brown \& Sharpe Manufacturing Company.
    In 1855 Brown invented a precision gear-cutting machine to make clock gears. The firm obtained in 1861 a contract to make Wilcox \& Gibbs sewing machines and gave up the manufacture of clocks. At about this time F.W. Howe of the Providence Tool Company arranged for Brown \& Sharpe to make a turret lathe required for the manufacture of muskets. This was basically Howe's design, but Brown added a few features, and it was the first machine tool built for sale by the Brown \& Sharpe Company. It was followed in 1862 by the universal milling machine invented by Brown initially for making twist drills. Particularly for cutting gear teeth, Brown invented in 1864 a formed milling cutter which could be sharpened without changing its profile. In 1867 the need for an instrument for checking the thickness of sheet material became apparent, and in August of that year J.R.Brown and L.Sharpe visited the Paris Exhibition and saw a micrometer calliper invented by Jean Laurent Palmer in 1848. They recognized its possibilities and with a few developments marketed it as a convenient, hand-held measuring instrument. Grinding lathes were made by Brown \& Sharpe in the early 1860s, and from 1868 a universal grinding machine was developed, with the first one being completed in 1876. The patent for this machine was granted after Brown's sudden death while on holiday.

  • 19 Gaskill, Harvey Freeman

    [br]
    b. 19 January 1845 Royalton, New York, USA
    d. 1 April 1889 Lockport, New York, USA
    [br]
    American mechanical engineer, inventor of the water-pumping engine with flywheel and reciprocating pumps.
    [br]
    Gaskill's father was a farmer near New York, where the son attended the local schools until he was 16 years old. At the age of 13 he already showed his mechanical aptitude by inventing a revolving hayrake, which was not exploited because the family had no money. His parents moved to Lockport, New York, where Harvey became a student at Lockport Union School and then the Poughkeepsie Commercial College, from which he graduated in 1866. After a period in his uncle's law office, he entered the firm of Penfield, Martin \& Gaskill to manufacture a patent clock. Then he was involved in a planing mill and a sash-and-blind manufactory. He devised a clothes spinner and a horse hayrake, but he did not manufacture them. In 1873 he became a draughtsman in the Holly Manufacturing Company in Lockport, which made pumping machinery for waterworks. He was promoted first to Engineer and then to Superintendent of the company in 1877. In 1885 he became a member of the Board of Directors and Vice-President. But for his untimely death, he might have become President. He was also a director of several other manufacturing concerns, public utilities and banks. In 1882 he produced a pump driven by a Woolf compound engine, which was the first time that rotary power with a crank and flywheel had been applied in waterworks. His design was more compact, more economical and lower in cost than previous types and gave the Holly Company a considerable advantage for a time over their main rivals, the Worthington Pump \& Machinery Company. These steam pumps became very popular in the United States and the type was also adopted in Britain.

  • 20 Macintosh, Charles

    [br]
    b. 29 December 1766 Glasgow, Scotland
    d. 25 July 1843 Dunchattan, near Glasgow, Scotland
    [br]
    Scottish inventor of rubberized waterproof clothing.
    [br]
    As the son of the well-known and inventive dyer George Macintosh, Charles had an early interest in chemistry. At the age of 19 he gave up his work as a clerk with a Glasgow merchant to manufacture sal ammoniac (ammonium chloride) and developed new processes in dyeing. In 1797 he started the first Scottish alum works, finding the alum in waste shale from coal mines. His first works was at Hurlet, Renfrewshire, and was followed later by others. He then formed a partnership with Charles Tennant, the proprietor of a chemical works at St Rollox, near Glasgow, and sold "lime bleaching liquor" made with chlorine and milk of lime from their bleach works at Darnley. A year later the use of dry lime to make bleaching powder, a process worked out by Macintosh, was patented. Macintosh remained associated with Tennant's St Rollox chemical works until 1814. During this time, in 1809, he had set up a yeast factory, but it failed because of opposition from the London brewers.
    There was a steady demand for the ammonia that gas works produced, but the tar was often looked upon as an inconvenient waste product. Macintosh bought all the ammonia and tar that the Glasgow works produced, using the ammonia in his establishment to produce cudbear, a dyestuff extracted from various lichens. Cudbear could be used with appropriate mordants to make shades from pink to blue. The tar could be distilled to produce naphtha, which was used as a flare. Macintosh also became interested in ironmaking. In 1825 he took out a patent for converting malleable iron into steel by taking it to white heat in a current of gas with a carbon content, such as coal gas. However, the process was not commercially successful because of the difficulty keeping the furnace gas-tight. In 1828 he assisted J.B. Neilson in bringing hot blast into use in blast furnaces; Neilson assigned Macintosh a share in the patent, which was of dubious benefit as it involved him in the tortuous litigation that surrounded the patent until 1843.
    In June 1823, as a result of experiments into the possible uses of naphtha obtained as a by-product of the distillation of coal tar, Macintosh patented his process for waterproofing fabric. This comprised dissolving rubber in naphtha and applying the solution to two pieces of cloth which were afterwards pressed together to form an impermeable compound fabric. After an experimental period in Glasgow, Macintosh commenced manufacture in Manchester, where he formed a partnership with H.H.Birley, B.Kirk and R.W.Barton. Birley was a cotton spinner and weaver and was looking for ways to extend the output of his cloth. He was amongst the first to light his mills with gas, so he shared a common interest with Macintosh.
    New buildings were erected for the production of waterproof cloth in 1824–5, but there were considerable teething troubles with the process, particularly in the spreading of the rubber solution onto the cloth. Peter Ewart helped to install the machinery, including a steam engine supplied by Boulton \& Watt, and the naphtha was supplied from Macintosh's works in Glasgow. It seems that the process was still giving difficulties when Thomas Hancock, the foremost rubber technologist of that time, became involved in 1830 and was made a partner in 1834. By 1836 the waterproof coat was being called a "mackintosh" [sic] and was gaining such popularity that the Manchester business was expanded with additional premises. Macintosh's business was gradually enlarged to include many other kinds of indiarubber products, such as rubber shoes and cushions.
