46 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 -
47 Booth, Hubert Cecil
SUBJECT AREA: Civil engineering, Domestic appliances and interiors, Mechanical, pneumatic and hydraulic engineering, Ports and shipping[br]b. 1871 Gloucester, England d. 1955[br]English mechanical, civil and construction engineer best remembered as the inventor of the vacuum cleaner.[br]As an engineer Booth contributed to the design of engines for Royal Navy battleships, designed and supervised the erection of a number of great wheels (in Blackpool, Vienna and Paris) and later designed factories and bridges.In 1900 he attended a demonstration, at St Paneras Station in London, of a new form of railway carriage cleaner that was supposed to blow the dirt into a container. It was not a very successful experiment and Booth, having considered the problem carefully, decided that sucking might be better than blowing. He tried out his idea by placing a piece of damp cloth over an upholstered armchair. When he sucked air by mouth through his cloth the dirt upon it was tangible proof of his theory.Various attempts were being made at this time, especially in America, to find a successful cleaner of carpets and upholstery. Booth produced the first truly satisfactory machine, which he patented in 1901, and coined the term "vacuum cleaner". He formed the Vacuum Cleaner Co. (later to become Goblin BVC Ltd) and began to manufacture his machines. For some years the company provided a cleaning service to town houses, using a large and costly vacuum cleaner (the first model cost £350). Painted scarlet, it measured 54×10×42 in. (137×25×110 cm) and was powered by a petrol-driven 5 hp piston engine. It was transported through the streets on a horse-driven van and was handled by a team of operators who parked outside the house to be cleaned. With the aid of several hundred feet of flexible hose extending from the cleaner through the windows into all the rooms, the machine sucked the dirt of decades from the carpets; at the first cleaning the weight of many such carpets was reduced by 50 per cent as the dirt was sucked away.Many attempts were made in Europe and America to produce a smaller and less expensive machine. Booth himself designed the chief British model in 1906, the Trolley- Vac, which was wheeled around the house on a trolley. Still elaborate, expensive and heavy, this machine could, however, be operated inside a room and was powered from an electric light fitting. It consisted of a sophisticated electric motor and a belt-driven rotary vacuum pump. Various hoses and fitments made possible the cleaning of many different surfaces and the dust was trapped in a cloth filter within a small metal canister. It was a superb vacuum cleaner but cost 35 guineas and weighed a hundredweight (50 kg), so it was difficult to take upstairs.Various alternative machines that were cheaper and lighter were devised, but none was truly efficient until a prototype that married a small electric motor to the machine was produced in 1907 in America.[br]Further ReadingThe Story of the World's First Vacuum Cleaner, Leatherhead: BSR (Housewares) Ltd.

48 Bullard, Edward Payson
SUBJECT AREA: Mechanical, pneumatic and hydraulic engineering[br]b. 18 April 1841 Uxbridge, Massachusetts, USAd. 22 December 1906 Bridgeport, Connecticut, USA[br]American mechanical engineer and machine-tool manufacturer who designed machines for boring.[br]Edward Payson Bullard served his apprenticeship at the Whitin Machine Works, Whitinsville, Massachusetts, and worked at the Colt Armory in Hartford, Connecticut, until 1863; he then entered the employ of Pratt \& Whitney, also in Hartford. He later formed a partnership with J.H.Prest and William Parsons manufacturing millwork and tools, the firm being known as Bullard \& Prest. In 1866 Bullard organized the Norwalk Iron Works Company of Norwalk, Connecticut, but afterwards withdrew and continued the business in Hartford. In 1868 the firm of Bullard \& Prest was dissolved and Bullard became Superintendent of a large machine shop in Athens, Georgia. He later organized the machine tool department of Post \& Co. at Cincinnati, and in 1872 he was made General Superintendent of the Gill Car Works at Columbus, Ohio. In 1875 he established a machinery business in Beekman Street, New York, under the name of Allis, Bullard \& Co. Mr Allis withdrew in 1877, and the Bullard Machine Company was organized.In 1880 Bullard secured entire control of the business and also became owner of the Bridgeport Machine Tool Works, Bridgeport, Connecticut. In 1883 he designed his first vertical boring and turning mill with a single head and belt feed and a 37 in. (94 cm) capacity; this was the first small boring machine designed to do the accurate work previously done on the face plate of a lathe. In 1889 Bullard gave up his New York interests and concentrated his entire attention on manufacturing at Bridgeport, the business being incorporated in 1894 as the Bullard Machine Tool Company. The company specialized in the construction of boring machines, the design being developed so that it became essentially a vertical turret lathe. After Bullard's death, his son Edward Payson Bullard II (b. 10 July 1872 Columbus, Ohio, USA; d. 26 June 1953 Fairfield, Connecticut, USA) continued as head of the company and further developed the boring machine into a vertical multi-spindle automatic lathe which he called the "Mult-au-matic" lathe. Both father and son were members of the American Society of Mechanical Engineers.[br]Further ReadingJ.W.Roe, 1916, English and American Tool Builders, New Haven: Yale University Press; repub. 1926, New York and 1987, Bradley, Ill.: Lindsay Publications Inc.

49 Clement (Clemmet), Joseph
SUBJECT AREA: Mechanical, pneumatic and hydraulic engineering[br]bapt. 13 June 1779 Great Asby, Westmoreland, Englandd. 28 February 1844 London, England[br]English machine tool builder and inventor.[br]Although known as Clement in his professional life, his baptism at Asby and his death were registered under the name of Joseph Clemmet. He worked as a slater until the age of 23, but his interest in mechanics led him to spend much of his spare time in the local blacksmith's shop. By studying books on mechanics borrowed from his cousin, a watchmaker, he taught himself and with the aid of the village blacksmith made his own lathe. By 1805 he was able to give up the slating trade and find employment as a mechanic in a small factory at Kirkby Stephen. From there he moved to Carlisle for two years, and then to Glasgow where, while working as a turner, he took lessons in drawing; he had a natural talent and soon became an expert draughtsman. From about 1809 he was employed by Leys, Mason \& Co. of Aberdeen designing and making power looms. For this work he built a screw-cutting lathe and continued his self-education. At the end of 1813, having saved about £100, he made his way to London, where he soon found employment as a mechanic and draughtsman. Within a few months he was engaged by Joseph Bramah, and after a trial period a formal agreement dated 1 April 1814 was made by which Clement was to be Chief Draughtsman and Superintendent of Bramah's Pimlico works for five years. However, Bramah died in December 1814 and after his sons took over the business it was agreed that Clement should leave before the expiry of the five-year period. He soon found employment as Chief Draughtsman with Henry Maudslay \& Co. By 1817 Clement had saved about £500, which enabled him to establish his own business at Prospect Place, Newington Butts, as a mechanical draughtsman and manufacturer of high-class machinery. For this purpose he built lathes for his own use and invented various improvements in their detailed design. In 1827 he designed and built a facing lathe which incorporated an ingenious system of infinitely variable belt gearing. He had also built his own planing machine by 1820 and another, much larger one in 1825. In 1828 Clement began making fluted taps and dies and standardized the screw threads, thus anticipating on a small scale the national standards later established by Sir Joseph Whitworth. Because of his reputation for first-class workmanship, Clement was in the 1820s engaged by Charles Babbage to carry out the construction of his first Difference Engine.[br]Principal Honours and DistinctionsSociety of Arts Gold Medal 1818 (for straightline mechanism), 1827 (for facing lathe); Silver Medal 1828 (for lathe-driving device).BibliographyExamples of Clement's draughtsmanship can be found in the Transactions of the Society of Arts 33 (1817), 36 (1818), 43 (1925), 46 (1828) and 48 (1829).Further ReadingS.Smiles, 1863, Industrial Biography, London, reprinted 1967, Newton Abbot (virtually the only source of biographical information on Clement).L.T.C.Rolt, 1965, Tools for the Job, London (repub. 1986); W.Steeds, 1969, A History of Machine Tools 1700–1910, Oxford (both contain descriptions of his machine tools).RTSBiographical history of technology > Clement (Clemmet), Joseph

He was Resident Engineer of the Cheshire Railroad at Walpote, New Hampshire, from 1847 to 1849, and then worked in independent practice as a civil engineer and surveyor until his death. He was involved with nearly all the railroads running out of Boston, especially the Boston \& Maine. In April 1863 he was appointed Chief Engineer of the Hoosac Tunnel, which was already being built. He introduced new engineering methods, relocated the line of the tunnel and achieved great accuracy in the meeting of the borings. He was largely responsible for the development in the USA of the advanced system of tunnelling with machinery and explosives, and pioneered the use of compressed air in the USA. In 1869 he was Chief Engineer of the Burlington \& Missouri River Railroad in Nebraska, laying down some 240 miles (386 km) of track in four years. During this period he became interested in the building of a Congregational College at Crete, Nebraska, for which he gave the land and which was named after him. In 1873 he returned to Charlestown and was again appointed Chief Engineer of the Hoosac Tunnel. At the final opening of the tunnel on 9 February 1875 he drove the first engine through. He remained in charge of construction for a further two years.[br]Principal Honours and DistinctionsPresident, School of Civil Engineers.Further ReadingDuncan Malone (ed.), 1932–3, Dictionary of American Biography, New York: Charles Scribner.IMcN -
51 Donkin, Bryan III
SUBJECT AREA: Mechanical, pneumatic and hydraulic engineering, Steam and internal combustion engines[br]b. 29 August 1835 London, Englandd. 4 March 1902 Brussels, Belgium[br]English mechanical engineer.[br]Bryan Donkin was the eldest son of John Donkin (1802–54) and grandson of Bryan Donkin I (1768–1855). He was educated at University College, London, and at the Ecole Centrale des Arts et Métiers in Paris, and then served an apprenticeship in the firm established by his grandfather. He assisted his uncle, Bryan Donkin II (1809–93), in setting up paper mills at St Petersburg. He became a partner in the Donkin firm in 1868 and Chairman in 1889, and retained this position after the amalgamation with Clench \& Co. of Chesterfield in 1900. Bryan Donkin was one of the first engineers to carry out scientific tests on steam engines and boilers, the results of his experiments being reported in many papers to the engineering institutions. In the 1890s his interests extended to the internal-combustion engine and he translated Rudolf Diesel's book Theory and Construction of a Rational Heat Motor. He was a frequent contributor to the weekly journal The Engineer. He was a member of the Institution of Civil Engineers and of the Institution of Mechanical Engineers, as well as of many other societies, including the Royal Institution, the American Society of Mechanical Engineers, the Société Industrielle de Mulhouse and the Verein Deutscher Ingenieure. In his experimental work he often collaborated with others, notably Professor A.B.W.Kennedy (1847–1928), with whom he was also associated in the consulting engineering firm of Kennedy \& Donkin.[br]Principal Honours and DistinctionsVice-President, Institution of Mechanical Engineers 1901.

SUBJECT AREA: Mechanical, pneumatic and hydraulic engineering[br]fl. 25/57 AD China[br]Chinese official of high rank and patron of engineers.[br]He was Prefect of Nanyang, a region that had long been noted as a centre for metallurgical operations. He devised or at least sponsored the construction of water-powered blowing engines (hydraulic reciprocators or shui pai) for blast furnaces and forges in ironworks for making agricultural implements. This invention is significant because it incorporated all the components needed to convert rotary motion to reciprocating motion. The only watermills previously known in China were those recorded by Huan Tan in the first century BC.[br]Further ReadingJoseph Needham, Science and Civilisation in China, Cambridge: Cambridge University Press, 1965, Vol. IV.2, pp. 31, 32, 85, 370, 377; Clerks and Craftsmen in China andthe West, 1970, pp. 119, 177, 186–7, 189.LRD -

[br]b. 222 Chinad. 284 China[br]Chinese general and engineer.[br]Du Yu was one of the generals who reduced the San Guo state of Wu for the Chin in 280. He is credited with the diffusion of the water-powered trip hammer and the multiple-geared watermill for the grinding of cereals. A battery of trip hammers was developed, operated by several shafts working off one large water-wheel. He was responsible for the construction of the Heyang pontoon bridges over the Yellow River north-east of Leyang in 274 and also devised new designs for water-powered blowing engines, against the advice of the imperial advisors but with the emperor's encouragement.[br]Further ReadingJoseph Needham, Science and Civilisation in China, Cambridge: Cambridge University Press, 1959–1965, Vols III, p. 601; IV. 1, p. 35, IV. 2, pp. 30, 86, 195, 393, 394, 396; IV. 3, pp. 160–1.LRD -

SUBJECT AREA: Mechanical, pneumatic and hydraulic engineering[br]b. 1806 London, Englandd. 11 April 1847 London, England[br]English mechanical engineer and author of Turning and Mechanical Manipulation.[br]Charles Holtzapffel was the son of John Holtzapffel, a native of Germany who settled in London c.1787 and set up as a manufacturer of lathes and tools for amateur mechanics. Charles Holtzapffel received a good English education and training in his father's workshop, and subsequently became a partner and ultimately succeeded to the business. He was engaged in the construction of machinery for printing banknotes, of lathes for cutting rosettes and for ornamental and plain turning. Holtzapffel is chiefly remembered for his monumental work entitled Turning and Mechanical Manipulation, intended as a work of general reference and practical instruction on the lathe. Publication began in 1843 and only the first two volumes were published in his lifetime. A third volume was edited by his widow from his notes and published shortly after his death. The fourth and fifth volumes were completed by his son, John Jacob Holtzapffel, more than thirty years later. Holtzapffel was an Associate of the Institution of Civil Engineers and served on its Council: he was also a member of the Society of Arts and Chairman of its Committee on Mechanics.RTS -

His outstanding achievement was to initiate the Guanxian (Kuanhsien) irrigation system, one of the world's greatest irrigation projects. North-west of Chengdu, capital of Szechuan province, the Min Jiang river tumbles from the Tibetan border country. It was distributed in some 735 miles (1,185 km) of channels into an irrigation system that fertilized half a million acres of good agricultural land and enabled a largely farming population of some 5 million to support themselves, with a regular water supply and free from drought and flood. In the ancient world, it can only be compared in scale with the works on the Nile in Ancient Egypt. The irrigation system was completed by his son Li Erlang c. 230 BC. At the time, it earned both Li Bing and his son temples in their honour; it survives to this day and is still impressive.[br]Further ReadingJ.Needham, Science and Civilisation in China, Cambridge: Cambridge University Press, 1971, vol.

56 Maudslay, Henry
SUBJECT AREA: Mechanical, pneumatic and hydraulic engineering[br]b. 22 August 1771 Woolwich, Kent, Englandd. 15 February 1831 Lambeth, London, England[br]English precision toolmaker and engineer.[br]Henry Maudslay was the third son of an ex-soldier and storekeeper at Woolwich Arsenal. At the age of 12 he was employed at the Arsenal filling cartridges; two years later he was transferred to the woodworking department, adjacent to the smithy, to which he moved when 15 years old. He was a rapid learner, and three years later Joseph Bramah took him on for the construction of special tools required for the mass-production of his locks. Maudslay was thus employed for the next eight years. He became Bramah's foreman, married his housekeeper, Sarah Tindale, and, unable to better himself, decided to leave and set up on his own. He soon outgrew his first premises in Wells Street and moved to Margaret Street, off Oxford Street, where some examples of his workmanship were displayed in the window. These caught the attention of a visiting Frenchman, de Bacquancourt; he was a friend of Marc Isambard Brunel, who was then in the early stages of designing the block-making machinery later installed at Portsmouth dockyard.Brunel wanted first a set of working models, as he did not think that the Lords of the Admiralty would be capable of understanding engineering drawings; Maudslay made these for him within the next two years. Sir Samuel Bentham, Inspector-General of Naval Works, agreed that Brunel's system was superior to the one that he had gone some way in developing; the Admiralty approved, and an order was placed for the complete plant. The manufacture of the machinery occupied Maudslay for the next six years; he was assisted by a draughtsman whom he took on from Portsmouth dockyard, Joshua Field (1786–1863), who became his partner in Maudslay, Son and Field. There were as many as eighty employees at Margaret Street until, in 1810, larger premises became necessary and a new works was built at Lambeth Marsh where, eventually, there were up to two hundred workers. The new factory was flanked by two houses, one of which was occupied by Maudslay, the other by Field. The firm became noted for its production of marine steam-engines, notably Maudslay's table engine which was first introduced in 1807.Maudslay was a consummate craftsman who was never happier than when working at his bench or at a machine tool; he was also one of the first engineers to appreciate the virtues of standardization. Evidence of this appreciation is to be found in his work in the development of the Bramah lock and then on the machine tools for the manufacture of ship's blocks to Marc Brunel's designs; possibly his most important contribution was the invention in 1797 of the metal lathe. He made a number of surface plates of the finest quality. The most celebrated of his numerous measuring devices was a micrometer-based machine which he termed his "Lord Chancellor" because, in the machine shop, it represented the "final court of appeal", measuring to one-thousandth of an inch.[br]Further Reading1934–5, "Maudslay, Sons \& Field as general engineers", Transactions of the Newcomen Society 15, London.1963, Engineering Heritage, Vol. 1, London: Institution of Mechanical Engineers.

57 Murray, Matthew
SUBJECT AREA: Land transport, Mechanical, pneumatic and hydraulic engineering, Railways and locomotives, Steam and internal combustion engines[br]b. 1765 near Newcastle upon Tyne, Englandd. 20 February 1826 Holbeck, Leeds, England[br]English mechanical engineer and steam engine, locomotive and machine-tool pioneer.[br]Matthew Murray was apprenticed at the age of 14 to a blacksmith who probably also did millwrighting work. He then worked as a journeyman mechanic at Stockton-on-Tees, where he had experience with machinery for a flax mill at Darlington. Trade in the Stockton area became slack in 1788 and Murray sought work in Leeds, where he was employed by John Marshall, who owned a flax mill at Adel, located about 5 miles (8 km) from Leeds. He soon became Marshall's chief mechanic, and when in 1790 a new mill was built in the Holbeck district of Leeds by Marshall and his partner Benyon, Murray was responsible for the installation of the machinery. At about this time he took out two patents relating to improvements in textile machinery.In 1795 he left Marshall's employment and, in partnership with David Wood (1761– 1820), established a general engineering and millwrighting business at Mill Green, Holbeck. In the following year the firm moved to a larger site at Water Lane, Holbeck, and additional capital was provided by two new partners, James Fenton (1754–1834) and William Lister (1796–1811). Lister was a sleeping partner and the firm was known as Fenton, Murray \& Wood and was organized so that Fenton kept the accounts, Wood was the administrator and took charge of the workshops, while Murray provided the technical expertise. The factory was extended in 1802 by the construction of a fitting shop of circular form, after which the establishment became known as the "Round Foundry".In addition to textile machinery, the firm soon began the manufacture of machine tools and steam-engines. In this field it became a serious rival to Boulton \& Watt, who privately acknowledged Murray's superior craftsmanship, particularly in foundry work, and resorted to some industrial espionage to discover details of his techniques. Murray obtained patents for improvements in steam engines in 1799, 1801 and 1802. These included automatic regulation of draught, a mechanical stoker and his short-D slide valve. The patent of 1801 was successfully opposed by Boulton \& Watt. An important contribution of Murray to the development of the steam engine was the use of a bedplate so that the engine became a compact, self-contained unit instead of separate components built into an en-gine-house.Murray was one of the first, if not the very first, to build machine tools for sale. However, this was not the case with the planing machine, which he is said to have invented to produce flat surfaces for his slide valves. Rather than being patented, this machine was kept secret, although it was apparently in use before 1814.In 1812 Murray was engaged by John Blenkinsop (1783–1831) to build locomotives for his rack railway from Middleton Colliery to Leeds (about 3 1/2 miles or 5.6 km). Murray was responsible for their design and they were fitted with two double-acting cylinders and cranks at right angles, an important step in the development of the steam locomotive. About six of these locomotives were built for the Middleton and other colliery railways and some were in use for over twenty years. Murray also supplied engines for many early steamboats. In addition, he built some hydraulic machinery and in 1814 patented a hydraulic press for baling cloth.Murray's son-in-law, Richard Jackson, later became a partner in the firm, which was then styled Fenton, Murray \& Jackson. The firm went out of business in 1843.[br]Principal Honours and DistinctionsSociety of Arts Gold Medal 1809 (for machine for hackling flax).Further ReadingL.T.C.Rolt, 1962, Great Engineers, London (contains a good short biography).E.Kilburn Scott (ed.), 1928, Matthew Murray, Pioneer Engineer, Leeds (a collection of essays and source material).C.F.Dendy Marshall, 1953, A History of Railway Locomotives Down to the End of theYear 1831, London.L.T.C.Rolt, 1965, Tools for the Job, London; repub. 1986 (provides information on Murray's machine-tool work).Some of Murray's correspondence with Simon Goodrich of the Admiralty has been published in Transactions of the Newcomen Society 3 (1922–3); 6(1925–6); 18(1937– 8); and 32 (1959–60).RTS -
58 Ramsden, Jesse
SUBJECT AREA: Mechanical, pneumatic and hydraulic engineering[br]b. 6 October 1735 (?) Halifax, Yorkshire, Englandd. 5 November 1800 Brighton, Sussex, England[br]English instrument-maker who developed machines for accurately measuring angular and linear scales.[br]Jesse Ramsden was the son of an innkeeper but received a good general education: after attending the free school at Halifax, he was sent at the age of 12 to his uncle for further study, particularly in mathematics. At the age of 16 he was apprenticed to a cloth-worker in Halifax and on completion of the apprenticeship in 1755 he moved to London to work as a clerk in a cloth warehouse. In 1758 he became an apprentice in the workshop of a London mathematical instrument-maker named Burton. He quickly gained the skill, particularly in engraving, and by 1762 he was able to set up on his own account. He married in 1765 or 1766 the youngest daughter of the optician John Dollond FRS (1706– 61) and received a share of Dollond's patent for making achromatic lenses.Ramsden's experience and reputation increased rapidly and he was generally regarded as the leading instrument-maker of his time. He opened a shop in the Haymarket and transferred to Piccadilly in 1775. His staff increased to about sixty workers and apprentices, and by 1789 he had constructed nearly 1,000 sextants as well as theodolites, micrometers, balances, barometers, quadrants and other instruments.One of Ramsden's most important contributions to precision measurement was his development of machines for obtaining accurate division of angular and linear scales. For this work he received a premium from the Commissioners of the Board of Longitude, who published his descriptions of the machines. For the trigonometrical survey of Great Britain, initiated by General William Roy FRS (1726–90) and continued by the Board of Ordnance, Ramsden supplied a 3 ft (91 cm) theodolite and steel measuring chains, and was also engaged to check the glass tubes used to measure the fundamental base line.[br]Principal Honours and DistinctionsFRS 1786; Royal Society Copley Medal 1795.

59 Reichenbach, Georg Friedrich von
SUBJECT AREA: Mechanical, pneumatic and hydraulic engineering, Photography, film and optics, Public utilities[br]b. 24 August 1772 Durlach, Baden, Germanyd. 21 May 1826 Munich, Germany[br]German engineer.[br]While he was attending the Military School at Mannheim, Reichenbach drew attention to himself due to the mathematical instruments that he had designed. On the recommendation of Count Rumford in Munich, the Bavarian government financed a two-year stay in Britain so that Reichenbach could become acquainted with modern mechanical engineering. He returned to Mannheim in 1793, and during the Napoleonic Wars he was involved in the manufacture of arms. In Munich, where he was in the service of the Bavarian state from 1796, he started producing precision instruments in his own time. His basic invention was the design of a dividing machine for circles, produced at the end of the eighteenth century. The astronomic and geodetic instruments he produced excelled all the others for their precision. His telescopes in particular, being perfect in use and of solid construction, soon brought him an international reputation. They were manufactured at the MathematicMechanical Institute, which he had jointly founded with Joseph Utzschneider and Joseph Liebherr in 1804 and which became a renowned training establishment. The glasses and lenses were produced by Joseph Fraunhofer who joined the company in 1807.In the same year he was put in charge of the technical reorganization of the salt-works at Reichenhall. After he had finished the brine-transport line from Reichenhall to Traunstein in 1810, he started on the one from Berchtesgaden to Reichenhall which was an extremely difficult task because of the mountainous area that had to be crossed. As water was the only source of energy available he decided to use water-column engines for pumping the brine in the pipes of both lines. Such devices had been in use for pumping purposes in different mining areas since the middle of the eighteenth century. Reichenbach knew about the one constructed by Joseph Karl Hell in Slovakia, which in principle had just been a simple piston-pump driven by water which did not work satisfactorily. Instead he constructed a really effective double-action water-column engine; this was a short time after Richard Trevithick had constructed a similar machine in England. For the second line he improved the system and built a single-action pump. All the parts of it were made of metal, which made them easy to produce, and the pumps proved to be extremely reliable, working for over 100 years.At the official opening of the line in 1817 the Bavarian king rewarded him generously. He remained in the state's service, becoming head of the department for roads and waterways in 1820, and he contributed to the development of Bavarian industry as well as the public infrastructure in many ways as a result of his mechanical skill and his innovative engineering mind.[br]Further ReadingBauernfeind, "Georg von Reichenbach" Allgemeine deutsche Biographie 27:656–67 (a reliable nineteenth-century account).W.Dyck, 1912, Georg v.

60 Roberts, Richard
[br]b. 22 April 1789 Carreghova, Llanymynech, Montgomeryshire, Walesd. 11 March 1864 London, England[br]Welsh mechanical engineer and inventor.[br]Richard Roberts was the son of a shoemaker and tollkeeper and received only an elementary education at the village school. At the age of 10 his interest in mechanics was stimulated when he was allowed by the Curate, the Revd Griffith Howell, to use his lathe and other tools. As a young man Roberts acquired a considerable local reputation for his mechanical skills, but these were exercised only in his spare time. For many years he worked in the local limestone quarries, until at the age of 20 he obtained employment as a pattern-maker in Staffordshire. In the next few years he worked as a mechanic in Liverpool, Manchester and Salford before moving in 1814 to London, where he obtained employment with Henry Maudslay. In 1816 he set up on his own account in Manchester. He soon established a reputation there for gear-cutting and other general engineering work, especially for the textile industry, and by 1821 he was employing about twelve men. He built machine tools mainly for his own use, including, in 1817, one of the first planing machines.One of his first inventions was a gas meter, but his first patent was obtained in 1822 for improvements in looms. His most important contribution to textile technology was his invention of the self-acting spinning mule, patented in 1825. The normal fourteen-year term of this patent was extended in 1839 by a further seven years. Between 1826 and 1828 Roberts paid several visits to Alsace, France, arranging cottonspinning machinery for a new factory at Mulhouse. By 1826 he had become a partner in the firm of Sharp Brothers, the company then becoming Sharp, Roberts \& Co. The firm continued to build textile machinery, and in the 1830s it built locomotive engines for the newly created railways and made one experimental steam-carriage for use on roads. The partnership was dissolved in 1843, the Sharps establishing a new works to continue locomotive building while Roberts retained the existing factory, known as the Globe Works, where he soon after took as partners R.G.Dobinson and Benjamin Fothergill (1802–79). This partnership was dissolved c. 1851, and Roberts continued in business on his own for a few years before moving to London as a consulting engineer.During the 1840s and 1850s Roberts produced many new inventions in a variety of fields, including machine tools, clocks and watches, textile machinery, pumps and ships. One of these was a machine controlled by a punched-card system similar to the Jacquard loom for punching rivet holes in plates. This was used in the construction of the Conway and Menai Straits tubular bridges. Roberts was granted twenty-six patents, many of which, before the Patent Law Amendment Act of 1852, covered more than one invention; there were still other inventions he did not patent. He made his contribution to the discussion which led up to the 1852 Act by publishing, in 1830 and 1833, pamphlets suggesting reform of the Patent Law.In the early 1820s Roberts helped to establish the Manchester Mechanics' Institute, and in 1823 he was elected a member of the Literary and Philosophical Society of Manchester. He frequently contributed to their proceedings and in 1861 he was made an Honorary Member. He was elected a Member of the Institution of Civil Engineers in 1838. From 1838 to 1843 he served as a councillor of the then-new Municipal Borough of Manchester. In his final years, without the assistance of business partners, Roberts suffered financial difficulties, and at the time of his death a fund for his aid was being raised.[br]Principal Honours and DistinctionsMember, Institution of Civil Engineers 1838.Further ReadingThere is no full-length biography of Richard Roberts but the best account is H.W.Dickinson, 1945–7, "Richard Roberts, his life and inventions", Transactions of the Newcomen Society 25:123–37.W.H.Chaloner, 1968–9, "New light on Richard Roberts, textile engineer (1789–1864)", Transactions of the Newcomen Society 41:27–44.RTS
