  • 8 Ellington, Edward Bayzard

    [br]
    b. 2 August 1845 London, England
    d. 10 November 1914 London, England
    [br]
    English hydraulic engineer who developed a direct-acting hydraulic lift.
    [br]
    Ellington was educated at Denmark Hill Grammar School, London, after which he became articled to John Penn of Greenwich. He stayed there until 1868, working latterly in the drawing office after a period of erecting plant and attending trials on board ship. For some twelve months he superintended the erection of Glengall Wharf, Old Kent Road, and the machinery used therein.
    In 1869 he went into partnership with Bryan Johnson of Chester, the company being known as Johnson \& Ellington, manufacturing mining and milling machinery. Under Ellington's influence, the firm specialized in the manufacture of hydraulic machinery. In 1874 the company acquired the right to manufacture the Brotherhood three-cylinder hydraulic engine; the company became the Hydraulic Engineering Company Ltd of Chester. Ellington developed a direct-acting hydraulic lift with a special balance arrangement that was smooth-acting and economical in water. He described the lift in a paper that was read to the Institution of Mechanical Engineers (IMechE) in 1882.
    Soon after Ellington joined the Chester firm, an Act of Parliament was passed, mainly due to his efforts, for the distribution of water under high pressure for the working of passenger and goods lifts and other hydraulic machinery in large towns. In 1872 he initiated the first hydraulic mains company at Hull, thus proving the practicability of the system of a high-pressure water-mains supply. Ellington remained as engineer to the Hull company until he was appointed a director in 1875. He was general manager and engineer of the General Hydraulic Power Company, which operated in London and had subsidiaries in Liverpool (opened in 1889), Manchester (1894) and Glasgow (1895). He maintained an interest in all these companies, as general manager and engineer, until his death.
    In 1895 he read another paper, "On hydraulic power in towns", to the Institution of Mechanical Engineers. In 1911 he became President of the IMechE; his Presidential Address was on the education of young engineers. In 1913 he delivered the Thomas Hawksley Lecture on "Water as a mechanical agent". He was Chairman of the Building Committee during the extension of the Institution's headquarters. Ellington was also a Member of Council of the Institution of Civil Engineers, a member of the Société des Ingé-nieurs Civils de France and a Governor of Imperial College of Science and Technology.

  • 9 Sperry, Elmer Ambrose

    [br]
    b. 21 October 1860 Cincinnatus, Cortland County, New York, USA
    d. 16 June 1930 Brooklyn, New York, USA
    [br]
    American entrepreneur who invented the gyrocompass.
    [br]
    Sperry was born into a farming community in Cortland County. He received a rudimentary education at the local school, but an interest in mechanical devices was aroused by the agricultural machinery he saw around him. His attendance at the Normal School in Cortland provided a useful theoretical background to his practical knowledge. He emerged in 1880 with an urge to pursue invention in electrical engineering, then a new and growing branch of technology. Within two years he was able to patent and demonstrate his arc lighting system, complete with its own generator, incorporating new methods of regulating its output. The Sperry Electric Light, Motor and Car Brake Company was set up to make and market the system, but it was difficult to keep pace with electric-lighting developments such as the incandescent lamp and alternating current, and the company ceased in 1887 and was replaced by the Sperry Electric Company, which itself was taken over by the General Electric Company.
    In the 1890s Sperry made useful inventions in electric mining machinery and then in electric street-or tramcars, with his patent electric brake and control system. The patents for the brake were important enough to be bought by General Electric. From 1894 to 1900 he was manufacturing electric motor cars of his own design, and in 1900 he set up a laboratory in Washington, where he pursued various electrochemical processes.
    In 1896 he began to work on the practical application of the principle of the gyroscope, where Sperry achieved his most notable inventions, the first of which was the gyrostabilizer for ships. The relatively narrow-hulled steamship rolled badly in heavy seas and in 1904 Ernst Otto Schuck, a German naval engineer, and Louis Brennan in England began experiments to correct this; their work stimulated Sperry to develop his own device. In 1908 he patented the active gyrostabilizer, which acted to correct a ship's roll as soon as it started. Three years later the US Navy agreed to try it on a destroyer, the USS Worden. The successful trials of the following year led to widespread adoption. Meanwhile, in 1910, Sperry set up the Sperry Gyroscope Company to extend the application to commercial shipping.
    At the same time, Sperry was working to apply the gyroscope principle to the ship's compass. The magnetic compass had worked well in wooden ships, but iron hulls and electrical machinery confused it. The great powers' race to build up their navies instigated an urgent search for a solution. In Germany, Anschütz-Kämpfe (1872–1931) in 1903 tested a form of gyrocompass and was encouraged by the authorities to demonstrate the device on the German flagship, the Deutschland. Its success led Sperry to develop his own version: fortunately for him, the US Navy preferred a home-grown product to a German one and gave Sperry all the backing he needed. A successful trial on a destroyer led to widespread acceptance in the US Navy, and Sperry was soon receiving orders from the British Admiralty and the Russian Navy.
    In the rapidly developing field of aeronautics, automatic stabilization was becoming an urgent need. In 1912 Sperry began work on a gyrostabilizer for aircraft. Two years later he was able to stage a spectacular demonstration of such a device at an air show near Paris.
    Sperry continued research, development and promotion in military and aviation technology almost to the last. In 1926 he sold the Sperry Gyroscope Company to enable him to devote more time to invention.

  • 11 Massey, Daniel

    [br]
    b. 1798 Vermont, USA
    d. 1856 Canada
    [br]
    American agricultural machinery manufacturer and co-founder of the Massey Harris Company (now Massey Ferguson).
    [br]
    In about 1800 Daniel Massey's family moved to Upper Canada. At the age of 6 he was sent back to stay with his grandparents in Waterton, USA, where he attended school for three years. He returned to his parents in 1807, and for the next twelve years he remained on his father's farm.
    At the age of 19 he forfeited his rights to his inheritance and rented land further west, which he began to clear. By the age of 21 he owned 200 acres, and during the next twelve years he bought, cleared and sold a further 1,200 acres. In 1820 he married Lucina Bradley from Water-town and returned with her to Canada.
    In 1830 he decided to settle down to farming and brought one of the first US threshing machines into Canada. From frequent visits to his family in the US he would return with new farm equipment, and in 1844 he handed his farm over to his eldest son so that he could concentrate on the development of his farm workshop. In 1845 he formed a brief partnership with R.F.Vaughan, who owned a small factory in Durham County near Lake Ontario. He began the production of ploughs, harrows, scufflers and rollers at a time when the Canadian Government was imposing heavy import duties on agricultural equipment being brought in from the USA. His business flourished and within six months he bought out his partner.
    In 1848 he bought another foundry in Newcastle, together with 50 acres of land, and in 1851 his son Hart joined him in the business. The following year Hart returned from the USA with the sole rights to manufacture the Ketchum mower and the Burrell reaper.
    The advent of the railway four years later opened up wider markets, and from these beginnings the Massey Company was to represent Canada at the Paris Exhibition of 1867. The European market was secured by the successes of the Massey reaper in the "World" trials held in France in 1889. Two years later the company merged with the Harris Company of Canada, to become the Massey Harris Company. Daniel Massey retired from the company four years after his son joined it, and he died the following year.

  • 12 McCormick, Cyrus

    [br]
    b. 1809 Walnut Grove, Virginia, USA
    d. 1884 USA
    [br]
    American inventor of the first functionally and commercially successful reaping machine; founder of the McCormick Company, which was to become one of the founding companies of International Harvester.
    [br]
    Cyrus McCormick's father, a farmer, began to experiment unsuccessfully with a harvesting machine between 1809 and 1816. His son took up the challenge and gave his first public demonstration of his machine in 1831. It cut a 4 ft swathe, but, wanting to perfect the machine, he waited until 1834 before patenting it, by which time he felt that his invention was threatened by others of similar design. In the same year he entered an article in the Mechanics Magazine, warning competitors off his design. His main rival was Obed Hussey who contested McCormick's claim to the originality of the idea, having patented his own machine six months before McCormick.
    A competition between the two machines was held in 1843, the judges favouring McCormick's, even after additional trials were conducted after objections of unfairness from Hussey. The rivalry continued over a number of years, being avidly reported in the agricultural press. The publicity did no harm to reaper sales, and McCormick sold twenty-nine machines in 1843 and fifty the following year.
    As the westward settlement movement progressed, so the demand for McCormick's machine grew. In order to be more central to his markets, McCormick established himself in Chicago. In partnership with C.M.Gray he established a factory to produce 500 harvesters for the 1848 season. By means of advertising and offers of credit terms, as well as production-line assembly, McCormick was able to establish himself as sole owner and also control all production, under the one roof. By the end of the decade he dominated reaper production but other developments were to threaten this position; however, foreign markets were appearing at the same time, not least the opportunities of European sales stimulated by the Great Exhibition in 1851. In the trials arranged by the Royal Agricultural Society of England the McCormick machine significantly outperformed that of Hussey's, and as a result McCormick arranged for 500 to be made under licence in England.
    In 1874 McCormick bought a half interest in the patent for a wire binder from Charles Withington, a watchmaker from Janesville, Wisconsin, and by 1885 a total of 50,000 wire binders had been built in Chicago. By 1881 McCormick was producing twine binders using Appleby's twine knotter under a licence agreement, and by 1885 the company was producing only twine binders. The McCormick Company was one of the co-founders of the International Harvester Company in 1901.

  • 13 Stephenson, George

    [br]
    b. 9 June 1781 Wylam, Northumberland, England
    d. 12 August 1848 Tapton House, Chesterfield, England
    [br]
    English engineer, "the father of railways".
    [br]
    George Stephenson was the son of the fireman of the pumping engine at Wylam colliery, and horses drew wagons of coal along the wooden rails of the Wylam wagonway past the house in which he was born and spent his earliest childhood. While still a child he worked as a cowherd, but soon moved to working at coal pits. At 17 years of age he showed sufficient mechanical talent to be placed in charge of a new pumping engine, and had already achieved a job more responsible than that of his father. Despite his position he was still illiterate, although he subsequently learned to read and write. He was largely self-educated.
    In 1801 he was appointed Brakesman of the winding engine at Black Callerton pit, with responsibility for lowering the miners safely to their work. Then, about two years later, he became Brakesman of a new winding engine erected by Robert Hawthorn at Willington Quay on the Tyne. Returning collier brigs discharged ballast into wagons and the engine drew the wagons up an inclined plane to the top of "Ballast Hill" for their contents to be tipped; this was one of the earliest applications of steam power to transport, other than experimentally.
    In 1804 Stephenson moved to West Moor pit, Killingworth, again as Brakesman. In 1811 he demonstrated his mechanical skill by successfully modifying a new and unsatisfactory atmospheric engine, a task that had defeated the efforts of others, to enable it to pump a drowned pit clear of water. The following year he was appointed Enginewright at Killingworth, in charge of the machinery in all the collieries of the "Grand Allies", the prominent coal-owning families of Wortley, Liddell and Bowes, with authorization also to work for others. He built many stationary engines and he closely examined locomotives of John Blenkinsop's type on the Kenton \& Coxlodge wagonway, as well as those of William Hedley at Wylam.
    It was in 1813 that Sir Thomas Liddell requested George Stephenson to build a steam locomotive for the Killingworth wagonway: Blucher made its first trial run on 25 July 1814 and was based on Blenkinsop's locomotives, although it lacked their rack-and-pinion drive. George Stephenson is credited with building the first locomotive both to run on edge rails and be driven by adhesion, an arrangement that has been the conventional one ever since. Yet Blucher was far from perfect and over the next few years, while other engineers ignored the steam locomotive, Stephenson built a succession of them, each an improvement on the last.
    During this period many lives were lost in coalmines from explosions of gas ignited by miners' lamps. By observation and experiment (sometimes at great personal risk) Stephenson invented a satisfactory safety lamp, working independently of the noted scientist Sir Humphry Davy who also invented such a lamp around the same time.
    In 1817 George Stephenson designed his first locomotive for an outside customer, the Kilmarnock \& Troon Railway, and in 1819 he laid out the Hetton Colliery Railway in County Durham, for which his brother Robert was Resident Engineer. This was the first railway to be worked entirely without animal traction: it used inclined planes with stationary engines, self-acting inclined planes powered by gravity, and locomotives.
    On 19 April 1821 Stephenson was introduced to Edward Pease, one of the main promoters of the Stockton \& Darlington Railway (S \& DR), which by coincidence received its Act of Parliament the same day. George Stephenson carried out a further survey, to improve the proposed line, and in this he was assisted by his 18-year-old son, Robert Stephenson, whom he had ensured received the theoretical education which he himself lacked. It is doubtful whether either could have succeeded without the other; together they were to make the steam railway practicable.
    At George Stephenson's instance, much of the S \& DR was laid with wrought-iron rails recently developed by John Birkinshaw at Bedlington Ironworks, Morpeth. These were longer than cast-iron rails and were not brittle: they made a track well suited for locomotives. In June 1823 George and Robert Stephenson, with other partners, founded a firm in Newcastle upon Tyne to build locomotives and rolling stock and to do general engineering work: after its Managing Partner, the firm was called Robert Stephenson \& Co.
    In 1824 the promoters of the Liverpool \& Manchester Railway (L \& MR) invited George Stephenson to resurvey their proposed line in order to reduce opposition to it. William James, a wealthy land agent who had become a visionary protagonist of a national railway network and had seen Stephenson's locomotives at Killingworth, had promoted the L \& MR with some merchants of Liverpool and had carried out the first survey; however, he overreached himself in business and, shortly after the invitation to Stephenson, became bankrupt. In his own survey, however, George Stephenson lacked the assistance of his son Robert, who had left for South America, and he delegated much of the detailed work to incompetent assistants. During a devastating Parliamentary examination in the spring of 1825, much of his survey was shown to be seriously inaccurate and the L \& MR's application for an Act of Parliament was refused. The railway's promoters discharged Stephenson and had their line surveyed yet again, by C.B. Vignoles.
    The Stockton \& Darlington Railway was, however, triumphantly opened in the presence of vast crowds in September 1825, with Stephenson himself driving the locomotive Locomotion, which had been built at Robert Stephenson \& Co.'s Newcastle works. Once the railway was at work, horse-drawn and gravity-powered traffic shared the line with locomotives: in 1828 Stephenson invented the horse dandy, a wagon at the back of a train in which a horse could travel over the gravity-operated stretches, instead of trotting behind.
    Meanwhile, in May 1826, the Liverpool \& Manchester Railway had successfully obtained its Act of Parliament. Stephenson was appointed Engineer in June, and since he and Vignoles proved incompatible the latter left early in 1827. The railway was built by Stephenson and his staff, using direct labour. A considerable controversy arose c. 1828 over the motive power to be used: the traffic anticipated was too great for horses, but the performance of the reciprocal system of cable haulage developed by Benjamin Thompson appeared in many respects superior to that of contemporary locomotives. The company instituted a prize competition for a better locomotive and the Rainhill Trials were held in October 1829.
    Robert Stephenson had been working on improved locomotive designs since his return from America in 1827, but it was the L \& MR's Treasurer, Henry Booth, who suggested the multi-tubular boiler to George Stephenson. This was incorporated into a locomotive built by Robert Stephenson for the trials: Rocket was entered by the three men in partnership. The other principal entrants were Novelty, entered by John Braithwaite and John Ericsson, and Sans Pareil, entered by Timothy Hackworth, but only Rocket, driven by George Stephenson, met all the organizers' demands; indeed, it far surpassed them and demonstrated the practicability of the long-distance steam railway. With the opening of the Liverpool \& Manchester Railway in 1830, the age of railways began.
    Stephenson was active in many aspects. He advised on the construction of the Belgian State Railway, of which the Brussels-Malines section, opened in 1835, was the first all-steam railway on the European continent. In England, proposals to link the L \& MR with the Midlands had culminated in an Act of Parliament for the Grand Junction Railway in 1833: this was to run from Warrington, which was already linked to the L \& MR, to Birmingham. George Stephenson had been in charge of the surveys, and for the railway's construction he and J.U. Rastrick were initially Principal Engineers, with Stephenson's former pupil Joseph Locke under them; by 1835 both Stephenson and Rastrick had withdrawn and Locke was Engineer-in-Chief. Stephenson remained much in demand elsewhere: he was particularly associated with the construction of the North Midland Railway (Derby to Leeds) and related lines. He was active in many other places and carried out, for instance, preliminary surveys for the Chester \& Holyhead and Newcastle \& Berwick Railways, which were important links in the lines of communication between London and, respectively, Dublin and Edinburgh.
    He eventually retired to Tapton House, Chesterfield, overlooking the North Midland. A man who was self-made (with great success) against colossal odds, he was ever reluctant, regrettably, to give others their due credit, although in retirement, immensely wealthy and full of honour, he was still able to mingle with people of all ranks.

    [br]
    b. c.1860 Biggleswade, Bedfordshire, England
    d. 1906 England
    [br]
    English engineer who developed and manufactured the first commercially successful lightweight tractor.
    [br]
    The son of a market gardener, Albone's interest lay in mechanics, and by 1880 he had established his own business as a cycle maker and repairer. His inventive mind led to a number of patents relating to bicycle design, but his commercial success was particularly assisted by his achievements in cycle racing. From this early start he diversified his business, designing and supplying, amongst other things, axle bearings for the Great Northern Railway, and also building motor cycles and several cars. It is possible that he began working on tractors as early as 1896. Certainly by 1902 he had built his first prototype, to the three-wheeled design that was to remain in later production models. Weighing only 30 cwt, yet capable of pulling two binders or a two-furrow plough, Albone's Ivel tractor was ahead of anything in its time, and its power-to-weight ratio was to be unrivalled for almost a decade. Albone's commercial success was not entirely due to the mechanical tractor's superiority, but owed a considerable amount to his ability as a showman and demonstrator. He held two working demonstrations a month in the village of Biggleswade in Bedfordshire, where the tractors were made. The tractor was named after the river Ivel, which flowed through the village. The Ivel tractor gained twenty-six gold and silver medals at agricultural shows between 1902 and 1906, and was a significant contributor to Britain's position as the world's largest exporter of tractors between 1904 and 1914. Albone tried other forms of his tractor to increase its sales. He built a fire engine, and also an armoured vehicle, but failed to impress the War Office with its potential.
    Albone died at the age of 46. His tractor continued in production but remained essentially unimproved, and the company finally lost its sales to other designs, particularly those of American origin.

    [br]
    b. 1840 New York, US A
    d. ? USA
    [br]
    American inventor of the knotting mechanism used on early binders and still found on modern baling machines.
    [br]
    As a young man John Appleby worked as a labourer for a farmer near Whitewater in Wisconsin. He was 18 when the farmer bought a new reaping machine. Appleby believed that the concept had not been progressed far enough and that the machine should be able to bind sheaths as well as to cut the corn. It is claimed that while watching a dog playing with a skipping rope he noticed a particular knot created as the dog removed its head from the loop that had passed over it, and recognized the potential of the way in which this knot had been formed. From a piece of apple wood he carved a device that would produce the knot he had seen. A local school teacher backed Appleby's idea with a $50 loan, but the American Civil War and service in the Union Army prevented any further development until 1869 when he took out a patent on a wire-tying binder. A number of the devices were made for him by a company in Beloit. Trials of wire binders held in 1873 highlighted the danger of small pieces of wire caught up in the hay leading to livestock losses. Appleby looked again at the possibility of twine. In 1875 he successfully operated a machine and the following season four were in operation. A number of other developments, not least Behel's "bill hook" knotting device, were also to have an influence in the final development of Appleby's twine-tying binder. As so often happens, it was the vision of the entrepreneur which ultimately led to the success of Appleby's device. In 1877 Appleby persuaded William Deering to produce and market his binder, and 3,000 twine binders, together with the twine produced for them, were put on the market in 1880, with immediate success. Over the next dozen years all harvesting-machine manufacturers adopted the idea, under licence to Appleby.

    SUBJECT AREA: Ports and shipping
    [br]
    b. 1810 Dartington, Devon, England
    d. 4 May 1879 Simonstown, South Africa
    [br]
    English naval architect; pioneer of experimental ship-model research.
    [br]
    Froude was educated at a preparatory school at Buckfastleigh, and then at Westminster School, London, before entering Oriel College, Oxford, to read mathematics and classics. Between 1836 and 1838 he served as a pupil civil engineer, and then he joined the staff of Isambard Kingdom Brunel on various railway engineering projects in southern England, including the South Devon Atmospheric Railway. He retired from professional work in 1846 and lived with his invalid father at Dartington Parsonage. The next twenty years, while apparently unproductive, were important to Froude as he concentrated his mind on difficult mathematical and scientific problems. Froude married in 1839 and had five children, one of whom, Robert Edmund Froude (1846–1924), was to succeed him in later years in his research work for the Admiralty. Following the death of his father, Froude moved to Paignton, and there commenced his studies on the resistance of solid bodies moving through fluids. Initially these were with hulls towed through a house roof storage tank by wires taken over a pulley and attached to falling weights, but the work became more sophisticated and was conducted on ponds and the open water of a creek near Dartmouth. Froude published work on the rolling of ships in the second volume of the Transactions of the then new Institution of Naval Architects and through this became acquainted with Sir Edward Reed. This led in 1870 to the Admiralty's offer of £2,000 towards the cost of an experimental tank for ship models at Torquay. The tank was completed in 1872 and tests were carried out on the model of HMS Greyhound following full-scale towing trials which had commenced on the actual ship the previous year. From this Froude enunciated his Law of Comparisons, which defines the rules concerning the relationship of the power required to move geometrically similar floating bodies across fluids. It enabled naval architects to predict, from a study of a much less expensive and smaller model, the resistance to motion and the power required to move a full-size ship. The work in the tank led Froude to design a model-cutting machine, dynamometers and machinery for the accurate ruling of graph paper. Froude's work, and later that of his son, was prodigious and covered many fields of ship design, including powering, propulsion, rolling, steering and stability. In only six years he had stamped his academic authority on the new science of hydrodynamics, served on many national committees and corresponded with fellow researchers throughout the world. His health suffered and he sailed for South Africa to recuperate, but he contracted dysentery and died at Simonstown. He will be remembered for all time as one of the greatest "fathers" of naval architecture.

    [br]
    American pioneer of steamships and of North American steam navigation.
    [br]
    The early life of Fulton is documented sparsely; however, it is clear that he was brought up in poor circumstances along with three sisters and one brother by a widowed mother. The War of Independence was raging around them for some years, but despite this it is believed that he spent some time learning the jeweller's trade in Philadelphia and had by then made a name for himself as a miniaturist. Throughout his life he remained skilled with his hands and well able to record technical detail on paper. He witnessed many of the early trials of American steamboats and saw the work of William Henry and John Fitch, and in 1787 he set off for the first time to Europe. For some years he examined steamships in Paris and without doubt saw the Charlotte Dundas on the Forth and Clyde Canal near Glasgow. In 1803 he built a steamship that ran on the Seine at 4 1/2 mph (7.25 km/h), and when it was lost, another to replace it. All his designs were based on principles that had been tried and proved elsewhere, and in this respect he was more of a developer than an inventor. After some time experimenting with submersibles and torpedoes for the British and French governments, in 1806 he returned to the United States. In 1807 he took delivery of the 100 ton displacement paddle steamer Clermont from the yard of Charles Browne of East River, New York. In August of that year it started the passenger services on the Hudson River and this can be claimed as the commencement of world passenger steam navigation. Again the ship was traditional in shape and the machinery was supplied by Messrs Boulton and Watt. This was followed by other ships, including Car of Neptune, Paragon and the world's first steam warship, Demolgos, launched in New York in October 1814 and designed by Fulton for coastal defence and the breaking of the British blockade. His last and finest boat was named Chancellor Livingston after his friend and patron Robert Livingston (1746–1813); the timber hull was launched in 1816, some months after Fulton's death.

    [br]
    b. 1818 Maentwrog, Merioneth (now Gwynedd), Wales
    d. 18 November 1889 Portmadoc (now Porthmadog), Wales
    [br]
    English engineer, pioneer of narrow-gauge steam railways.
    [br]
    At the age of 16 Charles Spooner helped his father, James, to build the Festiniog Railway, a horse-and-gravity tramroad; they maintained an even gradient and kept costs down by following a sinuous course along Welsh mountainsides and using a very narrow gauge. This was probably originally 2 ft 1 in. (63.5 cm) from rail centre to rail centre; with the introduction of heavier, and therefore wider, rails the gauge between them was reduced and was eventually standardized at 1 ft 11 1/2 in (60 cm). After James Spooner's death in 1856 Charles Spooner became Manager and Engineer of the Festiniog Railway and sought to introduce steam locomotives. Widening the gauge was impracticable, but there was no precedent for operating a public railway of such narrow gauge by steam. Much of the design work for locomotives for the Festiniog Railway was the responsibility of C.M.Holland, and many possible types were considered: eventually, in 1863, two very small 0–4–0 tank locomotives, with tenders for coal, were built by George England.
    These locomotives were successful, after initial problems had been overcome, and a passenger train service was introduced in 1865 with equal success. The potential for economical operation offered by such a railway attracted widespread attention, the more so because it had been effectively illegal to build new passenger railways in Britain to other than standard gauge since the Gauge of Railways Act of 1846.
    Spooner progressively improved the track, alignment, signalling and rolling stock of the Festiniog Railway and developed it from a tramroad to a miniaturized main line. Increasing traffic led to the introduction in 1869 of the 0–4–4–0 double-Fairlie locomotive Little Wonder, built to the patent of Robert Fairlie. This proved more powerful than two 0–4–0s and impressive demonstrations were given to engineers from many parts of the world, leading to the widespread adoption of narrow-gauge railways. Spooner himself favoured a gauge of 2 ft 6 in. (76 cm) or 2 ft 9 in. (84 cm). Comparison of the economy of narrow gauges with the inconvenience of a break of gauge at junctions with wider gauges did, however, become a continuing controversy, which limited the adoption of narrow gauges in Britain.
    Bogie coaches had long been used in North America but were introduced to Britain by Spooner in 1872, when he had two such coaches built for the Festiniog Railway. Both of these and one of its original locomotives, though much rebuilt, remain in service.
    Spooner, despite some serious illnesses, remained Manager of the Festiniog Railway until his death.
