8 Murdock (Murdoch), William
[br]b. 21 August 1754 Cumnock, Ayrshire, Scotlandd. 15 November 1839 Handsworth, Birmingham, England[br]Scottish engineer and inventor, pioneer in coal-gas production.[br]He was the third child and the eldest of three boys born to John Murdoch and Anna Bruce. His father, a millwright and joiner, spelled his name Murdock on moving to England. He was educated for some years at Old Cumnock Parish School and in 1777, with his father, he built a "wooden horse", supposed to have been a form of cycle. In 1777 he set out for the Soho manufactory of Boulton \& Watt, where he quickly found employment, Boulton supposedly being impressed by the lad's hat. This was oval and made of wood, and young William had turned it himself on a lathe of his own manufacture. Murdock quickly became Boulton \& Watt's representative in Cornwall, where there was a flourishing demand for steam-engines. He lived at Redruth during this period.It is said that a number of the inventions generally ascribed to James Watt are in fact as much due to Murdock as to Watt. Examples are the piston and slide valve and the sun-and-planet gearing. A number of other inventions are attributed to Murdock alone: typical of these is the oscillating cylinder engine which obviated the need for an overhead beam.In about 1784 he planned a steam-driven road carriage of which he made a working model. He also planned a high-pressure non-condensing engine. The model carriage was demonstrated before Murdock's friends and travelled at a speed of 6–8 mph (10–13 km/h). Boulton and Watt were both antagonistic to their employees' developing independent inventions, and when in 1786 Murdock set out with his model for the Patent Office, having received no reply to a letter he had sent to Watt, Boulton intercepted him on the open road near Exeter and dissuaded him from going any further.In 1785 he married Mary Painter, daughter of a mine captain. She bore him four children, two of whom died in infancy, those surviving eventually joining their father at the Soho Works. Murdock was a great believer in pneumatic power: he had a pneumatic bell-push at Sycamore House, his home near Soho. The pattern-makers lathe at the Soho Works worked for thirty-five years from an air motor. He also conceived the idea of a vacuum piston engine to exhaust a pipe, later developed by the London Pneumatic Despatch Company's railway and the forerunner of the atmospheric railway.Another field in which Murdock was a pioneer was the gas industry. In 1791, in Redruth, he was experimenting with different feedstocks in his home-cum-office in Cross Street: of wood, peat and coal, he preferred the last. He designed and built in the backyard of his house a prototype generator, washer, storage and distribution plant, and publicized the efficiency of coal gas as an illuminant by using it to light his own home. In 1794 or 1795 he informed Boulton and Watt of his experimental work and of its success, suggesting that a patent should be applied for. James Watt Junior was now in the firm and was against patenting the idea since they had had so much trouble with previous patents and had been involved in so much litigation. He refused Murdock's request and for a short time Murdock left the firm to go home to his father's mill. Boulton \& Watt soon recognized the loss of a valuable servant and, in a short time, he was again employed at Soho, now as Engineer and Superintendent at the increased salary of £300 per year plus a 1 per cent commission. From this income, he left £14,000 when he died in 1839.In 1798 the workshops of Boulton and Watt were permanently lit by gas, starting with the foundry building. The 180 ft (55 m) façade of the Soho works was illuminated by gas for the Peace of Paris in June 1814. By 1804, Murdock had brought his apparatus to a point where Boulton \& Watt were able to canvas for orders. Murdock continued with the company after the death of James Watt in 1819, but retired in 1830 and continued to live at Sycamore House, Handsworth, near Birmingham.[br]Principal Honours and DistinctionsRoyal Society Rumford Gold Medal 1808.Further ReadingS.Smiles, 1861, Lives of the Engineers, Vol. IV: Boulton and Watt, London: John Murray.H.W.Dickinson and R.Jenkins, 1927, James Watt and the Steam Engine, Oxford: Clarendon Press.J.A.McCash, 1966, "William Murdoch.

9 Watt, James
SUBJECT AREA: Steam and internal combustion engines[br]b. 19 January 1735 Greenock, Renfrewshire, Scotlandd. 19 August 1819 Handsworth Heath, Birmingham, England[br]Scottish engineer and inventor of the separate condenser for the steam engine.[br]The sixth child of James Watt, merchant and general contractor, and Agnes Muirhead, Watt was a weak and sickly child; he was one of only two to survive childhood out of a total of eight, yet, like his father, he was to live to an age of over 80. He was educated at local schools, including Greenock Grammar School where he was an uninspired pupil. At the age of 17 he was sent to live with relatives in Glasgow and then in 1755 to London to become an apprentice to a mathematical instrument maker, John Morgan of Finch Lane, Cornhill. Less than a year later he returned to Greenock and then to Glasgow, where he was appointed mathematical instrument maker to the University and was permitted in 1757 to set up a workshop within the University grounds. In this position he came to know many of the University professors and staff, and it was thus that he became involved in work on the steam engine when in 1764 he was asked to put in working order a defective Newcomen engine model. It did not take Watt long to perceive that the great inefficiency of the Newcomen engine was due to the repeated heating and cooling of the cylinder. His idea was to drive the steam out of the cylinder and to condense it in a separate vessel. The story is told of Watt's flash of inspiration as he was walking across Glasgow Green one Sunday afternoon; the idea formed perfectly in his mind and he became anxious to get back to his workshop to construct the necessary apparatus, but this was the Sabbath and work had to wait until the morrow, so Watt forced himself to wait until the Monday morning.Watt designed a condensing engine and was lent money for its development by Joseph Black, the Glasgow University professor who had established the concept of latent heat. In 1768 Watt went into partnership with John Roebuck, who required the steam engine for the drainage of a coal-mine that he was opening up at Bo'ness, West Lothian. In 1769, Watt took out his patent for "A New Invented Method of Lessening the Consumption of Steam and Fuel in Fire Engines". When Roebuck went bankrupt in 1772, Matthew Boulton, proprietor of the Soho Engineering Works near Birmingham, bought Roebuck's share in Watt's patent. Watt had met Boulton four years earlier at the Soho works, where power was obtained at that time by means of a water-wheel and a steam engine to pump the water back up again above the wheel. Watt moved to Birmingham in 1774, and after the patent had been extended by Parliament in 1775 he and Boulton embarked on a highly profitable partnership. While Boulton endeavoured to keep the business supplied with capital, Watt continued to refine his engine, making several improvements over the years; he was also involved frequently in legal proceedings over infringements of his patent.In 1794 Watt and Boulton founded the new company of Boulton \& Watt, with a view to their retirement; Watt's son James and Boulton's son Matthew assumed management of the company. Watt retired in 1800, but continued to spend much of his time in the workshop he had set up in the garret of his Heathfield home; principal amongst his work after retirement was the invention of a pantograph sculpturing machine.James Watt was hard-working, ingenious and essentially practical, but it is doubtful that he would have succeeded as he did without the business sense of his partner, Matthew Boulton. Watt coined the term "horsepower" for quantifying the output of engines, and the SI unit of power, the watt, is named in his honour.[br]Principal Honours and DistinctionsFRS 1785.

10 Buckle, William
SUBJECT AREA: Mechanical, pneumatic and hydraulic engineering[br]b. 29 July 1794 Alnwick, Northumberland, Englandd. 30 September 1863 London, England[br]English mechanical engineer who introduced the first large screw-cutting lathe to Boulton, Watt \& Co.[br]William Buckle was the son of Thomas Buckle (1759–1849), a millwright who later assisted the 9th Earl of Dundonald (1749–1831) in his various inventions, principally machines for the manufacture of rope. Soon after the birth of William, the family moved from Alnwick to Hull, Yorkshire, where he received his education. The family again moved c.1808 to London, and William was apprenticed to Messrs Woolf \& Edwards, millwrights and engineers of Lambeth. During his apprenticeship he attended evening classes at a mechanical drawing school in Finsbury, which was then the only place of its kind in London.After completing his apprenticeship, he was sent by Messrs Humphrys to Memel in Prussia to establish steamboats on the rivers and lakes there under the patronage of the Prince of Hardenburg. After about four years he returned to Britain and was employed by Boulton, Watt \& Co. to install the engines in the first steam mail packet for the service between Dublin and Holyhead. He was responsible for the engines of the steamship Lightning when it was used on the visit of George IV to Ireland.About 1824 Buckle was engaged by Boulton, Watt \& Co. as Manager of the Soho Foundry, where he is credited with introducing the first large screw-cutting lathe. At Soho about 700 or 800 men were employed on a wide variety of engineering manufacture, including coining machinery for mints in many parts of the world, with some in 1826 for the Mint at the Soho Manufactory. In 1851, following the recommendations of a Royal Commission, the Royal Mint in London was reorganized and Buckle was asked to take the post of Assistant Coiner, the senior executive officer under the Deputy Master. This he accepted, retaining the post until the end of his life.At Soho, Buckle helped to establish a literary and scientific institution to provide evening classes for the apprentices and took part in the teaching. He was an original member of the Institution of Mechanical Engineers, which was founded in Birmingham in January 1847, and a member of their Council from then until 1855. He contributed a number of papers in the early years, including a memoir of William Murdock whom he had known at Soho; he resigned from the Institution in 1856 after his move to London. He was an honorary member of the London Association of Foreman Engineers.[br]Bibliography1850, "Inventions and life of William Murdock", Proceedings of the Institution of Mechanical Engineers 2 (October): 16–26.RTS -
11 Ewart, Peter
SUBJECT AREA: Textiles[br]b. 14 May 1767 Traquair, near Peebles, Scotlandd. September 1842 London, England[br]Scottish pioneer in the mechanization of the textile industry.[br]Peter Ewart, the youngest of six sons, was born at Traquair manse, where his father was a clergyman in the Church of Scotland. He was educated at the Free School, Dumfries, and in 1782 spent a year at Edinburgh University. He followed this with an apprenticeship under John Rennie at Musselburgh before moving south in 1785 to help Rennie erect the Albion corn mill in London. This brought him into contact with Boulton \& Watt, and in 1788 he went to Birmingham to erect a waterwheel and other machinery in the Soho Manufactory. In 1789 he was sent to Manchester to install a steam engine for Peter Drinkwater and thus his long connection with the city began. In 1790 Ewart took up residence in Manchester as Boulton \& Watt's representative. Amongst other engines, he installed one for Samuel Oldknow at Stockport. In 1792 he became a partner with Oldknow in his cotton-spinning business, but because of financial difficulties he moved back to Birmingham in 1795 to help erect the machines in the new Soho Foundry. He was soon back in Manchester in partnership with Samuel Greg at Quarry Bank Mill, Styal, where he was responsible for developing the water power, installing a steam engine, and being concerned with the spinning machinery and, later, gas lighting at Greg's other mills.In 1798, Ewart devised an automatic expansion-gear for steam engines, but steam pressures at the time were too low for such a device to be effective. His grasp of the theory of steam power is shown by his paper to the Manchester Literary and Philosophical Society in 1808, On the Measure of Moving Force. In 1813 he patented a power loom to be worked by the pressure of steam or compressed air. In 1824 Charles Babbage consulted him about automatic looms. His interest in textiles continued until at least 1833, when he obtained a patent for a self-acting spinning mule, which was, however, outclassed by the more successful one invented by Richard Roberts. Ewart gave much help and advice to others. The development of the machine tools at Boulton \& Watt's Soho Foundry has been mentioned already. He also helped James Watt with his machine for copying sculptures. While he continued to run his own textile mill, Ewart was also in partnership with Charles Macintosh, the pioneer of rubber-coated cloth. He was involved with William Fairbairn concerning steam engines for the boats that Fairbairn was building in Manchester, and it was through Ewart that Eaton Hodgkinson was introduced to Fairbairn and so made the tests and calculations for the tubes for the Britannia Railway Bridge across the Menai Straits. Ewart was involved with the launching of the Liverpool \& Manchester Railway as he was a director of the Manchester Chamber of Commerce at the time.In 1835 he uprooted himself from Manchester and became the first Chief Engineer for the Royal Navy, assuming responsibility for the steamboats, which by 1837 numbered 227 in service. He set up repair facilities and planned workshops for overhauling engines at Woolwich Dockyard, the first establishment of its type. It was here that he was killed in an accident when a chain broke while he was supervising the lifting of a large boiler. Engineering was Ewart's life, and it is possible to give only a brief account of his varied interests and connections here.[br]Further ReadingObituary, 1843, "Institution of Civil Engineers", Annual General Meeting, January.

12 Hornblower, Jonathan
SUBJECT AREA: Steam and internal combustion engines[br]b. 1753 Cornwall (?), Englandd. 1815 Penryn, Cornwall, England[br]English mining engineer who patented an early form of compound steam engine.[br]Jonathan came from a family with an engineering tradition: his grandfather Joseph had worked under Thomas Newcomen. Jonathan was the sixth child in a family of thirteen whose names all began with "J". In 1781 he was living at Penryn, Cornwall and described himself as a plumber, brazier and engineer. As early as 1776, when he wished to amuse himself by making a small st-eam engine, he wanted to make something new and wondered if the steam would perform more than one operation in an engine. This was the foundation for his compound engine. He worked on engines in Cornwall, and in 1778 was Engineer at the Ting Tang mine where he helped Boulton \& Watt erect one of their engines. He was granted a patent in 1781 and in that year tried a large-scale experiment by connecting together two engines at Wheal Maid. Very soon John Winwood, a partner in a firm of iron founders at Bristol, acquired a share in the patent, and in 1782 an engine was erected in a colliery at Radstock, Somerset. This was probably not very successful, but a second was erected in the same area. Hornblower claimed greater economy from his engines, but steam pressures at that time were not high enough to produce really efficient compound engines. Between 1790 and 1794 ten engines with his two-cylinder arrangement were erected in Cornwall, and this threatened Boulton \& Watt's near monopoly. At first the steam was condensed by a surface condenser in the bottom of the second, larger cylinder, but this did not prove very successful and later a water jet was used. Although Boulton \& Watt proceeded against the owners of these engines for infringement of their patent, they did not take Jonathan Hornblower to court. He tried a method of packing the piston rod by a steam gland in 1781 and his work as an engineer must have been quite successful, for he left a considerable fortune on his death.[br]Bibliography1781, British patent no. 1,298 (compound steam engine).Further ReadingR.Jenkins, 1979–80, "Jonathan Hornblower and the compound engine", Transactions of the Newcomen Society 11.J.Tann, 1979–80, "Mr Hornblower and his crew, steam engine pirates in the late 18th century", Transactions of the Newcomen Society 51.J.Farey, 1827, A Treatise on the Steam Engine, Historical, Practical and Descriptive, reprinted 1971, Newton Abbot: David \& Charles (an almost contemporary account of the compound engine).D.S.L.Cardwell, 1971, From Watt to Clausius.

13 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.

14 Wilkinson, John
SUBJECT AREA: Weapons and armour[br]b. 1728 Clifton, Cumberland, Englandd. 14 July 1808 Bradley, Staffordshire, England[br]English ironmaster, inventor of a cannon-boring machine.[br]Wilkinson's father Isaac was a farmer turned ironmaster. Soon after 1750, the family acquired Bersham furnace, near Wrexham. This was later in the hands of John and his brother William. By 1763, John had risen to take sole charge of Broseley furnace near Coalbrookdale, Shropshire, and in 1770 he set up a third furnace at Bradley, Staffordshire. By this time he had become one of the country's leading ironmasters, known for the wide range of ware made of cast iron, doubtless the reason for his nickname "Ironmad Wilkinson". He made a cast-iron boat which, to the surprise of many, floated. For his own eventual use, he also made a cast-iron coffin, but did not make sufficient allowance for increasing girth with age! Wilkinson's most notable invention was his cannon-boring machine, patented in 1774. The gun barrel was held rigidly while the cutter head moved forward on a rod inside a hollow boring bar. The machine was easily adapted to bore the cylinders for Boulton \& Watt's steam engines and he became a regular supplier, as only he could bore them with the required accuracy. On the other hand, their second engine was supplied to Wilkinson to power a blowing engine to provide air blast for his Broseley furnace: this was the first use of a Boulton \& Watt engine for a purpose other than pumping. By 1780 he had three further steam engines at work. Wilkinson installed the first Boulton \& Watt engine in France at the Paris waterworks, for which he supplied the iron pipes. Another patent was obtained in 1794 for the invention of the cupola or furnace for melting metal for small castings, although it is now thought that the real inventor was his brother William. Apart from domestic and engineering ironware, Wilkinson was supplier of arms to the American and, illicitly, to the French.[br]Further ReadingH.W.Dickinson, 1914, John Wilkinson, Iron-master.LRD -

18 Austin, John
SUBJECT AREA: Textiles[br]fl. 1789 Scotland[br]Scottish contributor to the early development of the power loom.[br]On 6 April 1789 John Austin wrote to James Watt, seeking advice about patenting "a weaving loom I have invented to go by the hand, horse, water or any other constant power, to comb, brush, or dress the yarn at the same time as it is weaving \& by which one man will do the work of three and make superior work to what can be done by the common loom" (Boulton \& Watt Collection, Birmingham, James Watt Papers, JW/22). Watt replied that "there is a Clergyman by the name of Cartwright at Doncaster who has a patent for a similar contrivance" (Boulton \& Watt Collection, Birmingham, Letter Book 1, 15 April 1789). Watt pointed out that there was a large manufactory running at Doncaster and something of the same kind at Manchester with working power looms. Presumably, this reply deterred Austin from taking out a patent. However, some members of the Glasgow Chamber of Commerce continued developing the loom, and in 1798 one that was tried at the spinning mill of J.Monteith, of Pollokshaws, near Glasgow, answered the purpose so well that a building was erected and thirty of the looms were installed. Later, in 1800, this number was increased to 200, all of which were driven by a steam engine, and it was stated that one weaver and a boy could tend from three to five of these looms.Austin's loom was worked by eccentrics, or cams. There was one cam on each side with "a sudden beak or projection" that drove the levers connected to the picking pegs, while other cams worked the heddles and drove the reed. The loom was also fitted with a weft stop motion and could produce more cloth than a hand loom, and worked at about sixty picks per minute. The pivoting of the slay at the bottom allowed the loom to be much more compact than previous ones.[br]Further ReadingA.Rees, 1819, The Cyclopaedia: or Universal Dictionary of Arts, Sciences and Literature, London.R.Guest, 1823, A Compendius History of the Cotton Manufacture, Manchester.A.P.Usher, 1958, A History of Mechanical Inventions.W.English, 1969, The Textile Industry, London.R.L.Hills, 1970, Power in the Industrial Revolution, Manchester.See also: Cartwright, Revd EdmundRLH -
19 Boulsover, Thomas
[br]b. 1704d. 1788[br]English cutler, metalworker and inventor of Sheffield plate.[br]Boulsover, originally a small-scale manufacturer of cutlery, is believed to have specialized in making knife-handle components. About 1742 he found that a thin sheet of silver could be fused to copper sheet by rolling or beating to flatten it. Thus he developed the plating of silver, later called Sheffield plate.The method when perfected consisted of copper sheet overlaid by thin sheet silver being annealed by red heat. Protected by iron sheeting, the copper and silver were rolled together, becoming fused to a single plate capable of undergoing further manufacturing processes. Later developments included methods of edging the fused sheets and the placing of silver sheet on both lower and upper surfaces of copper, to produce high-quality silver plate, in much demand by the latter part of the century. Boulsover himself is said to have produced only small articles such as buttons and snuff boxes from this material, which by 1758 was being exploited more commercially by Joseph Hancock in Sheffield making candlesticks, hot-water pots and coffee pots. Matthew Boulton introduced its manufacture in very high-quality products during the 1760s to Birmingham, where the technique was widely adopted later. By the 1770s Boulsover was engaged in rolling his plated copper for industry elsewhere, also trading in iron and purchasing blister steel which he converted by the Huntsman process to crucible steel. Blister steel was converted on his behalf to shear steel by forging. He is thought to have also been responsible for improving this product further, introducing "double-shear steel", by repeating the forging and faggoting of shear steel bars. Thomas Boulsover had become a Sheffield entrepreneur, well known for his numerous skills with metals.[br]Further ReadingH.W.Dickinson, 1937, Matthew Boulton, Cambridge: Cambridge University Press (describes Boulsover's innovation and further development of Sheffield plate).J.Holland, 1834, Manufactures in Metal III, 354–8.For activities in steel see: K.C.Barraclough, 1991, "Steel in the Industrial Revolution", in J.Day and R.F.Tylecote (eds), The Industrial Revolution in Metals, The Institute of Metals.JD -
20 Gilbert, John
[br]b. 1724 Cotton Hall, Cotton, Staffordshire, Englandd. 3 August 1795 Worsley, Lancashire, England[br]English land agent, mining engineer and canal entrepreneur.[br]Younger son of a gentleman farmer, Gilbert was apprenticed to Matthew Boulton, a buckle maker of Birmingham and father of the Matthew Boulton who was associated with James Watt. He also gained mining experience. Through the influence of his older brother, Thomas Gilbert, he became Land Agent to the Duke of Bridgewater (Francis Egerton) for the Worsley estate. He proposed extensions to the underground waterway system and also made a preliminary survey for a canal from Worsley to Salford, a project which Brindley joined as Assistant Engineer. Gilbert was therefore the prime mover in the construction of the Bridgewater Canal, which received its Act in 1759. He then collected evidence for the second Act to permit construction of the aqueduct across the Irwell at Barton. He was involved in a consortium with his brother Thomas and Earl Gower to develop the Earl's East Shropshire mines and to build the Shrewsbury and the Shropshire Coal Canals. He also excavated the Speedwell Mine at Castleton in Derbyshire between 1774 and 1781 and constructed the underground canal to serve the workings. With his brother, he was involved in the promotion of the Trent \& Mersey Canal and was a shareholder in the undertaking. Among his other entrepreneurial activities, he entered the canal-carrying business. His last work was beginning the underground inclined planes at Worsley, but these were not completed until after his death. His important place in the historical development of the inland navigational system in England has been very much overlooked.[br]Further ReadingP.Lead, 1990, Agents of Revolution: John and Thomas Gilbert-Entrepreneurs, Keele University Centre for Local History.JHB
