6 Chapelon, André
[br]b. 26 October 1892 Saint-Paul-en-Cornillon, Loire, Franced. 29 June 1978 Paris, France[br]French locomotive engineer who developed high-performance steam locomotives.[br]Chapelon's technical education at the Ecole Centrale des Arts et Manufactures, Paris, was interrupted by extended military service during the First World War. From experience of observing artillery from the basket of a captive balloon, he developed a method of artillery fire control which was more accurate than that in use and which was adopted by the French army.In 1925 he joined the motive-power and rolling-stock department of the Paris-Orléans Railway under Chief Mechanical Engineer Maurice Lacoin and was given the task of improving the performance of its main-line 4–6–2 locomotives, most of them compounds. He had already made an intensive study of steam locomotive design and in 1926 introduced his Kylchap exhaust system, based in part on the earlier work of the Finnish engineer Kyläla. Chapelon improved the entrainment of the hot gases in the smokebox by the exhaust steam and so minimized back pressure in the cylinders, increasing the power of a locomotive substantially. He also greatly increased the cross-sectional area of steam passages, used poppet valves instead of piston valves and increased superheating of steam. PO (Paris-Orléans) 4–6–2s rebuilt on these principles from 1929 onwards proved able to haul 800-ton trains, in place of the previous 500-ton trains, and to do so to accelerated schedules with reduced coal consumption. Commencing in 1932, some were converted, at the time of rebuilding, into 4–8–0s to increase adhesive weight for hauling heavy trains over the steeply graded Paris-Toulouse line.Chapelon's principles were quickly adopted on other French railways and elsewhere.H.N. Gresley was particularly influenced by them. After formation of the French National Railways (SNCF) in 1938, Chapelon produced in 1941 a prototype rebuilt PO 2–10–0 freight locomotive as a six-cylinder compound, with four low-pressure cylinders to maximize expansive use of steam and with all cylinders steam-jacketed to minimize heat loss by condensation and radiation. War conditions delayed extended testing until 1948–52. Meanwhile Chapelon had, by rebuilding, produced in 1946 a high-powered, three-cylinder, compound 4–8–4 intended as a stage in development of a proposed range of powerful and thermally efficient steam locomotives for the postwar SNCF: a high-speed 4–6–4 in this range was to run at sustained speeds of 125 mph (200 km/h). However, plans for improved steam locomotives were then overtaken in France by electriflcation and dieselization, though the performance of the 4–8–4, which produced 4,000 hp (3,000 kW) at the drawbar for the first time in Europe, prompted modification of electric locomotives, already on order, to increase their power.Chapelon retired from the SNCF in 1953, but continued to act as a consultant. His principles were incorporated into steam locomotives built in France for export to South America, and even after the energy crisis of 1973 he was consulted on projects to build improved, high-powered steam locomotives for countries with reserves of cheap coal. The eventual fall in oil prices brought these to an end.[br]Bibliography1938, La Locomotive à vapeur, Paris: J.B.Bailière (a comprehensive summary of contemporary knowledge of every function of the locomotive).Further ReadingH.C.B.Rogers, 1972, Chapelon, Genius of French Steam, Shepperton: Ian Allan.1986, "André Chapelon, locomotive engineer: a survey of his work", Transactions of the Newcomen Society 58 (a symposium on Chapelon's work).Obituary, 1978, Railway Engineer (September/October) (makes reference to the technical significance of Chapelon's work).PJGR -
7 Trevithick, Richard
[br]b. 13 April 1771 Illogan, Cornwall, Englandd. 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.[br]BibliographyTrevithick took out fourteen patents, solely or in partnership, of which the most important are: 1802, Construction of Steam Engines, British patent no. 2,599. 1808, Stowing Ships' Cargoes, British patent no. 3,172.Further ReadingH.W.Dickinson and A.Titley, 1934, Richard Trevithick.

9 Rittinger, Peter von
SUBJECT AREA: Mining and extraction technology[br]b. 23 January 1811 Neutitschein, Moravia (now Now Jicin, Czech Republic)d. 7 December 1872 Vienna, Austria[br]Austrian mining engineer, improver of the processing of minerals.[br]After studying law, philosophy and politics at the University of Olmutz (now Olomouc), in 1835 Rittinger became a fellow of the Mining Academy in Schemnitz (now Banská Štiavnica), Slovakia. In 1839, the year he finished at the academy, he published a book on perspective drawing. The following year, he became Inspector of Mills at the ore mines in Schemnitz, and in 1845 he was engaged in coal mining in Bohemia and Moravia. In 1849 he joined the mining administration at Joachimsthal (now Jáchymov), Bohemia. In these early years he contributed his first important innovations for the mining industry and thus fostered his career in the government's service. In 1850 he was called to Vienna to become a high-ranked officer in various ministries. He was responsible for the construction of buildings, pumping installations and all sorts of machinery in the mining industry; he reorganized the curricula of the mining schools, was responsible for the mint and became head of the department of mines, forests and salt-works in the Austrian empire.During all his years of public service, Rittinger continued his concern with technological innovations. He improved the processing of ores by introducing in 1844 the rotary washer and the box classifier, and later his continuously shaking concussion table which, having been exhibited at the Vienna World Fair of 1873, was soon adopted in other countries. He constructed water-column pumps, invented a differential shaft pump with hydraulic linkage to replace the heavy iron rods and worked on centrifugal pumps. He was one of the first to be concerned with the transfer of heat, and he developed a system of using exhaust steam for heating in salt-works. He kept his eye on current developments abroad, using his function as official Austrian commissioner to the world exhibitions, on which he published frequently as well as on other matters related to technology. With his systematic handbook on mineral processing, first published in 1867, he emphasized his international reputation in this specialized field of mining.[br]Principal Honours and DistinctionsKnighted 1863.

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

13 Corliss, George Henry
SUBJECT AREA: Steam and internal combustion engines[br]b. 2 June 1817 Easton, Washington City, New York, USAd. 21 February 1888 USA[br]American inventor of a cut-off mechanism linked to the governor which revolutionized the operation of steam engines.[br]Corliss's father was a physician and surgeon. The son was educated at Greenwich, New York, but while he showed an aptitude for mathematics and mechanics he first of all became a storekeeper and then clerk, bookkeeper, salesperson and official measurer and inspector of the cloth produced at W.Mowbray \& Son. He went to the Castleton Academy, Vermont, for three years and at the age of 21 returned to a store of his own in Greenwich. Complaints about stitching in the boots he sold led him to patent a sewing machine. He approached Fairbanks, Bancroft \& Co., Providence, Rhode Island, machine and steam engine builders, about producing his machine, but they agreed to take him on as a draughtsman providing he abandoned it. Corliss moved to Providence with his family and soon revolutionized the design and construction of steam engines. Although he started working out ideas for his engine in 1846 and completed one in 1848 for the Providence Dyeing, Bleaching and Calendering Company, it was not until March 1849 that he obtained a patent. By that time he had joined John Barstow and E.J.Nightingale to form a new company, Corliss Nightingale \& Co., to build his design of steam-engines. He used paired valves, two inlet and two exhaust, placed on opposite sides of the cylinder, which gave good thermal properties in the flow of steam. His wrist-plate operating mechanism gave quick opening and his trip mechanism allowed the governor to regulate the closure of the inlet valve, giving maximum expansion for any load. It has been claimed that Corliss should rank equally with James Watt in the development of the steam-engine. The new company bought land in Providence for a factory which was completed in 1856 when the Corliss Engine Company was incorporated. Corliss directed the business activities as well as technical improvements. He took out further patents modifying his valve gear in 1851, 1852, 1859, 1867, 1875, 1880. The business grew until well over 1,000 workers were employed. The cylindrical oscillating valve normally associated with the Corliss engine did not make its appearance until 1850 and was included in the 1859 patent. The impressive beam engine designed for the 1876 Centennial Exhibition by E. Reynolds was the product of Corliss's works. Corliss also patented gear-cutting machines, boilers, condensing apparatus and a pumping engine for waterworks. While having little interest in politics, he represented North Providence in the General Assembly of Rhode Island between 1868 and 1870.[br]Further ReadingMany obituaries appeared in engineering journals at the time of his death.

15 Baumann, Karl
SUBJECT AREA: Steam and internal combustion engines[br]b. 18 April 1884 Switzerlandd. 14 July 1971 Ilkley, Yorkshire[br]Swiss/British mechanical engineer, designer and developer of steam and gas turbine plant.[br]After leaving school in 1902, he went to the Ecole Polytechnique, Zurich, leaving in 1906 with an engineering diploma. He then spent a year with Professor A.Stodola, working on steam engines, turbines and internal combustion engines. He also conducted research in the strength of materials. After this, he spent two years as Research and Design Engineer at the Nuremberg works of Maschinenfabrik Augsburg-Nürnberg. He came to England in 1909 to join the British Westinghouse Co. Ltd in Manchester, and by 1912 was Chief Engineer of the Engine Department of that firm. The firm later became the Metropolitan-Vickers Electrical Co. Ltd (MV), and Baumann rose from Chief Mechanical Engineer through to, by 1929, Special Director and Member of the Executive Management Board; he remained a director until his retirement in 1949.For much of his career, Baumann was in the forefront of power station steam-cycle development, pioneering increased turbine entry pressures and temperatures, in 1916 introducing multi-stage regenerative feed-water heating and the Baumann turbine multi-exhaust. His 105 MW set for Battersea "A" station (1933) was for many years the largest single-axis unit in Europe. From 1938 on, he and his team were responsible for the first axial-flow aircraft propulsion gas turbines to fly in England, and jet engines in the 1990s owe much to the "Beryl" and "Sapphire" engines produced by MV. In particular, the design of the compressor for the Sapphire engine later became the basis for Rolls-Royce units, after an exchange of information between that company and Armstrong-Siddeley, who had previously taken over the aircraft engine work of MV.Further, the Beryl engine formed the basis of "Gatric", the first marine gas turbine propulsion engine.Baumann was elected to full membership for the Institution of Mechanical Engineers in 1929 and a year later was awarded the Thomas Hawksley Gold Medal by that body, followed by their James Clayton Prize in 1948: in the same year he became the thirty-fifth Thomas Hawksley lecturer. Many of his ideas and introductions have stood the test of time, being based on his deep and wide understanding of fundamentals.JB -
16 Gresley, Sir Herbert Nigel
[br]b. 19 June 1876 Edinburgh, Scotlandd. 5 April 1941 Hertford, England[br]English mechanical engineer, designer of the A4-class 4–6–2 locomotive holding the world speed record for steam traction.[br]Gresley was the son of the Rector of Netherseale, Derbyshire; he was educated at Marlborough and by the age of 13 was skilled at making sketches of locomotives. In 1893 he became a pupil of F.W. Webb at Crewe works, London \& North Western Railway, and in 1898 he moved to Horwich works, Lancashire \& Yorkshire Railway, to gain drawing-office experience under J.A.F.Aspinall, subsequently becoming Foreman of the locomotive running sheds at Blackpool. In 1900 he transferred to the carriage and wagon department, and in 1904 he had risen to become its Assistant Superintendent. In 1905 he moved to the Great Northern Railway, becoming Superintendent of its carriage and wagon department at Doncaster under H.A. Ivatt. In 1906 he designed and produced a bogie luggage van with steel underframe, teak body, elliptical roof, bowed ends and buckeye couplings: this became the prototype for East Coast main-line coaches built over the next thirty-five years. In 1911 Gresley succeeded Ivatt as Locomotive, Carriage \& Wagon Superintendent. His first locomotive was a mixed-traffic 2–6–0, his next a 2–8–0 for freight. From 1915 he worked on the design of a 4–6–2 locomotive for express passenger traffic: as with Ivatt's 4 4 2s, the trailing axle would allow the wide firebox needed for Yorkshire coal. He also devised a means by which two sets of valve gear could operate the valves on a three-cylinder locomotive and applied it for the first time on a 2–8–0 built in 1918. The system was complex, but a later simplified form was used on all subsequent Gresley three-cylinder locomotives, including his first 4–6–2 which appeared in 1922. In 1921, Gresley introduced the first British restaurant car with electric cooking facilities.With the grouping of 1923, the Great Northern Railway was absorbed into the London \& North Eastern Railway and Gresley was appointed Chief Mechanical Engineer. More 4–6– 2s were built, the first British class of such wheel arrangement. Modifications to their valve gear, along lines developed by G.J. Churchward, reduced their coal consumption sufficiently to enable them to run non-stop between London and Edinburgh. So that enginemen might change over en route, some of the locomotives were equipped with corridor tenders from 1928. The design was steadily improved in detail, and by comparison an experimental 4–6–4 with a watertube boiler that Gresley produced in 1929 showed no overall benefit. A successful high-powered 2–8–2 was built in 1934, following the introduction of third-class sleeping cars, to haul 500-ton passenger trains between Edinburgh and Aberdeen.In 1932 the need to meet increasing road competition had resulted in the end of a long-standing agreement between East Coast and West Coast railways, that train journeys between London and Edinburgh by either route should be scheduled to take 8 1/4 hours. Seeking to accelerate train services, Gresley studied high-speed, diesel-electric railcars in Germany and petrol-electric railcars in France. He considered them for the London \& North Eastern Railway, but a test run by a train hauled by one of his 4–6–2s in 1934, which reached 108 mph (174 km/h), suggested that a steam train could better the railcar proposals while its accommodation would be more comfortable. To celebrate the Silver Jubilee of King George V, a high-speed, streamlined train between London and Newcastle upon Tyne was proposed, the first such train in Britain. An improved 4–6–2, the A4 class, was designed with modifications to ensure free running and an ample reserve of power up hill. Its streamlined outline included a wedge-shaped front which reduced wind resistance and helped to lift the exhaust dear of the cab windows at speed. The first locomotive of the class, named Silver Link, ran at an average speed of 100 mph (161 km/h) for 43 miles (69 km), with a maximum speed of 112 1/2 mph (181 km/h), on a seven-coach test train on 27 September 1935: the locomotive went into service hauling the Silver Jubilee express single-handed (since others of the class had still to be completed) for the first three weeks, a round trip of 536 miles (863 km) daily, much of it at 90 mph (145 km/h), without any mechanical troubles at all. Coaches for the Silver Jubilee had teak-framed, steel-panelled bodies on all-steel, welded underframes; windows were double glazed; and there was a pressure ventilation/heating system. Comparable trains were introduced between London Kings Cross and Edinburgh in 1937 and to Leeds in 1938.Gresley did not hesitate to incorporate outstanding features from elsewhere into his locomotive designs and was well aware of the work of André Chapelon in France. Four A4s built in 1938 were equipped with Kylchap twin blast-pipes and double chimneys to improve performance still further. The first of these to be completed, no. 4468, Mallard, on 3 July 1938 ran a test train at over 120 mph (193 km/h) for 2 miles (3.2 km) and momentarily achieved 126 mph (203 km/h), the world speed record for steam traction. J.Duddington was the driver and T.Bray the fireman. The use of high-speed trains came to an end with the Second World War. The A4s were then demonstrated to be powerful as well as fast: one was noted hauling a 730-ton, 22-coach train at an average speed exceeding 75 mph (120 km/h) over 30 miles (48 km). The war also halted electrification of the Manchester-Sheffield line, on the 1,500 volt DC overhead system; however, anticipating eventual resumption, Gresley had a prototype main-line Bo-Bo electric locomotive built in 1941. Sadly, Gresley died from a heart attack while still in office.[br]Principal Honours and DistinctionsKnighted 1936. President, Institution of Locomotive Engineers 1927 and 1934.

17 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.

18 Silk Noils
Silk noils may be divided into two major divisions, i.e., Schappe noils, produced on the Continent, and English noils. The broad difference is that whereas the former are not free from the natural gum of the silkworm, the latter have the gum fully discharged. Owing to the difference of the processes of which they are the outcome, the English noil is whiter and longer than the schappe noil. The English noil in its turn is of two kinds "long" and "exhaust." The long noil is the simple by-product of the flat-dressing frame, and the exhaust (or short) noil has been recombed and is more " neppy " than the material from which it came. All silk noils, long or short, schappe or English, may be divided into " white " and " tussah " according as they are the produce of one kind of silk or the other. The white has many sub-divisions (" China " and " Italian," " Steam," etc.) and the tussah may be light or dark brown according as its origin is Chinese or Indian waste silk. These noils, after spinning, appear as noil yarns, which are useful among other purposes as striping yarn for cheap tweeds. They are also useful substitutes for " spun " silk at three to four times the price. Noils are used in the production of fancy effects by Continental spinners of the so-called " imitation " yarns. And in Yorkshire silk noils are periodically required by costume and dress tweed makers for procuring " knop " or snowflake effects in cheap woollens. For this purpose the " short " or " exhaust " noil is preferable to the " long " and in some circumstances the short or re-combed noil fetches a higher price than the intrinsically better noil containing the long fibre. -

20 Fairlie, Robert Francis
[br]b. March 1831 Scotlandd. 31 July 1885 Clapham, London, England[br]British engineer, designer of the double-bogie locomotive, advocate of narrow-gauge railways.[br]Fairlie worked on railways in Ireland and India, and established himself as a consulting engineer in London by the early 1860s. In 1864 he patented his design of locomotive: it was to be carried on two bogies and had a double boiler, the barrels extending in each direction from a central firebox. From smokeboxes at the outer ends, return tubes led to a single central chimney. At that time in British practice, locomotives of ever-increasing size were being carried on longer and longer rigid wheelbases, but often only one or two of their three or four pairs of wheels were powered. Bogies were little used and then only for carrying-wheels rather than driving-wheels: since their pivots were given no sideplay, they were of little value. Fairlie's design offered a powerful locomotive with a wheelbase which though long would be flexible; it would ride well and have all wheels driven and available for adhesion.The first five double Fairlie locomotives were built by James Cross \& Co. of St Helens during 1865–7. None was particularly successful: the single central chimney of the original design had been replaced by two chimneys, one at each end of the locomotive, but the single central firebox was retained, so that exhaust up one chimney tended to draw cold air down the other. In 1870 the next double Fairlie, Little Wonder, was built for the Festiniog Railway, on which C.E. Spooner was pioneering steam trains of very narrow gauge. The order had gone to George England, but the locomotive was completed by his successor in business, the Fairlie Engine \& Steam Carriage Company, in which Fairlie and George England's son were the principal partners. Little Wonder was given two inner fireboxes separated by a water space and proved outstandingly successful. The spectacle of this locomotive hauling immensely long trains up grade, through the Festiniog Railway's sinuous curves, was demonstrated before engineers from many parts of the world and had lasting effect. Fairlie himself became a great protagonist of narrow-gauge railways and influenced their construction in many countries.Towards the end of the 1860s, Fairlie was designing steam carriages or, as they would now be called, railcars, but only one was built before the death of George England Jr precipitated closure of the works in 1870. Fairlie's business became a design agency and his patent locomotives were built in large numbers under licence by many noted locomotive builders, for narrow, standard and broad gauges. Few operated in Britain, but many did in other lands; they were particularly successful in Mexico and Russia.Many Fairlie locomotives were fitted with the radial valve gear invented by Egide Walschaert; Fairlie's role in the universal adoption of this valve gear was instrumental, for he introduced it to Britain in 1877 and fitted it to locomotives for New Zealand, whence it eventually spread worldwide. Earlier, in 1869, the Great Southern \& Western Railway of Ireland had built in its works the first "single Fairlie", a 0–4–4 tank engine carried on two bogies but with only one of them powered. This type, too, became popular during the last part of the nineteenth century. In the USA it was built in quantity by William Mason of Mason Machine Works, Taunton, Massachusetts, in preference to the double-ended type.Double Fairlies may still be seen in operation on the Festiniog Railway; some of Fairlie's ideas were far ahead of their time, and modern diesel and electric locomotives are of the powered-bogie, double-ended type.[br]Bibliography1864, British patent no. 1,210 (Fairlie's master patent).1864, Locomotive Engines, What They Are and What They Ought to Be, London; reprinted 1969, Portmadoc: Festiniog Railway Co.
