  • 121 Churchward, George Jackson

    [br]
    b. 31 January 1857 Stoke Gabriel, Devon, England
    d. 19 December 1933 Swindon, Wiltshire, England
    [br]
    English mechanical engineer who developed for the Great Western Railway a range of steam locomotives of the most advanced design of its time.
    [br]
    Churchward was articled to the Locomotive Superintendent of the South Devon Railway in 1873, and when the South Devon was absorbed by the Great Western Railway in 1876 he moved to the latter's Swindon works. There he rose by successive promotions to become Works Manager in 1896, and in 1897 Chief Assistant to William Dean, who was Locomotive Carriage and Wagon Superintendent, in which capacity Churchward was allowed extensive freedom of action. Churchward eventually succeeded Dean in 1902: his title changed to Chief Mechanical Engineer in 1916.
    In locomotive design, Churchward adopted the flat-topped firebox invented by A.J.Belpaire of the Belgian State Railways and added a tapered barrel to improve circulation of water between the barrel and the firebox legs. He designed valves with a longer stroke and a greater lap than usual, to achieve full opening to exhaust. Passenger-train weights had been increasing rapidly, and Churchward produced his first 4–6– 0 express locomotive in 1902. However, he was still developing the details—he had a flair for selecting good engineering practices—and to aid his development work Churchward installed at Swindon in 1904 a stationary testing plant for locomotives. This was the first of its kind in Britain and was based on the work of Professor W.F.M.Goss, who had installed the first such plant at Purdue University, USA, in 1891. For comparison with his own locomotives Churchward obtained from France three 4–4–2 compound locomotives of the type developed by A. de Glehn and G. du Bousquet. He decided against compounding, but he did perpetuate many of the details of the French locomotives, notably the divided drive between the first and second pairs of driving wheels, when he introduced his four-cylinder 4–6–0 (the Star class) in 1907. He built a lone 4–6–2, the Great Bear, in 1908: the wheel arrangement enabled it to have a wide firebox, but the type was not perpetuated because Welsh coal suited narrow grates and 4–6–0 locomotives were adequate for the traffic. After Churchward retired in 1921 his successor, C.B.Collett, was to enlarge the Star class into the Castle class and then the King class, both 4–6–0s, which lasted almost as long as steam locomotives survived in service. In Church ward's time, however, the Great Western Railway was the first in Britain to adopt six-coupled locomotives on a large scale for passenger trains in place of four-coupled locomotives. The 4–6–0 classes, however, were but the most celebrated of a whole range of standard locomotives of advanced design for all types of traffic and shared between them many standardized components, particularly boilers, cylinders and valve gear.

  • 122 Garratt, Herbert William

    [br]
    b. 8 June 1864 London, England
    d. 25 September 1913 Richmond, Surrey, England
    [br]
    English engineer, inventor of the Beyer-Garratt articulated locomotive.
    [br]
    After apprenticeship at the North London Railway's locomotive works, Garratt had a varied career which included responsibility for the locomotive departments of several British-owned railways overseas. This gave him an insight into the problems of such lines: locomotives, which were often inadequate, had to be operated over lines with weak bridges, sharp curves and steep gradients. To overcome these problems, he designed an articulated locomotive in which the boiler, mounted on a girder frame, was sus pended between two power bogies. This enabled a wide firebox and large-diameter boiler barrel to be combined with large driving-wheels and good visibility. Coal and water containers were mounted directly upon the bogies to keep them steady. The locomotive was inherently stable on curves because the central line of the boiler between its pivots lay within the curve of the centre line of the track. Garratt applied for a patent for his locomotive in 1907 and manufacture was taken up by Beyer, Peacock \& Co. under licence: the type became known as the Beyer-Garratt. The earliest Beyer-Garratt locomotives were small, but subsequent examples were larger. Sadly, only twenty-six locomotives of the type had been built or were under construction when Garratt died in 1913. Subsequent classes came to include some of the largest and most powerful steam locomotives: they were widely used and particularly successful in Central and Southern Africa, where examples continue to give good service in the 1990s.

  • 123 Gurney, Sir Goldsworthy

    [br]
    b. 14 February 1793 Treator, near Padstow, Cornwall, England
    d. 28 February 1875 Reeds, near Bude, Cornwall, England
    [br]
    English pioneer of steam road transport.
    [br]
    Educated at Truro Grammar School, he then studied under Dr Avery at Wadebridge to become a doctor of medicine. He settled as a surgeon in Wadebridge, spending his leisure time in building an organ and in the study of chemistry and mechanical science. He married Elizabeth Symons in 1814, and in 1820 moved with his wife to London. He delivered a course of lectures at the Surrey Institution on the elements of chemical science, attended by, amongst others, the young Michael Faraday. While there, Gurney made his first invention, the oxyhydrogen blowpipe. For this he received the Gold Medal of the Society of Arts. He experimented with lime and magnesia for the production of an illuminant for lighthouses with some success. He invented a musical instrument of glasses played like a piano.
    In 1823 he started experiments related to steam and locomotion which necessitated taking a partner in to his medical practice, from which he resigned shortly after. His objective was to produce a steam-driven vehicle to run on common roads. His invention of the steam-jet of blast greatly improved the performance of the steam engine. In 1827 he took his steam carriage to Cyfarthfa at the request of Mr Crawshaw, and while there applied his steam-jet to the blast furnaces, greatly improving their performance in the manufacture of iron. Much of the success of George Stephenson's steam engine, the Rocket was due to Gurney's steam blast.
    In July 1829 Gurney made a historic trip with his road locomotive. This was from London to Bath and back, which was accomplished at a speed of 18 mph (29 km/h) and was made at the instigation of the Quartermaster-General of the Army. So successful was the carriage that Sir Charles Dance started to run a regular service with it between Gloucester and Cheltenham. This ran for three months without accident, until Parliament introduced prohibitive taxation on all self-propelled vehicles. A House of Commons committee proposed that these should be abolished as inhibiting progress, but this was not done. Sir Goldsworthy petitioned Parliament on the harm being done to him, but nothing was done and the coming of the railways put the matter beyond consideration. He devoted his time to finding other uses for the steam-jet: it was used for extinguishing fires in coal-mines, some of which had been burning for many years; he developed a stove for the production of gas from oil and other fatty substances, intended for lighthouses; he was responsible for the heating and the lighting of both the old and the new Houses of Parliament. His evidence after a colliery explosion resulted in an Act of Parliament requiring all mines to have two shafts. He was knighted in 1863, the same year that he suffered a stroke which incapacitated him. He retired to his house at Reeds, near Bude, where he was looked after by his daughter, Anna.

    SUBJECT AREA: Land transport
    [br]
    b. 26 October 1803 York, England
    d. 29 June 1883 Fulham, London, England
    [br]
    English architect and inventor, originator of the Hansom cab.
    [br]
    In 1816 he was apprenticed to his father, who was a joiner. After a year his abilities in design and construction were so marked that it was decided that he would have more scope as an architect. He was accordingly apprenticed to a Mr Phillips in York, becoming a clerk to Phillips in 1820. While he served his time he also worked on his own account and taught at a night school. In 1825 he married Hannah Glover and settled in Halifax, where he became Assistant to another architect. In 1828 he became a partner of Edward Welch, with whom he built a number of churches in the north of England. He designed the Town Hall for Birmingham and was responsible for the constructional work until 1833, but he had to become bond because the builders caused him to become bankrupt. He was appointed Manager of the business affairs of Dempster Hemming of Caldicote Hall, which included the landed estates, banking and coal-mining. It was during this period that he designed the "Patent Safety Cab" named after him and popular in Victorian days. The safety element consisted in lowering the centre of gravity by the use of the cranked axle. Hansom sold his rights for £10,000 to a company proposing to exploit the patent, but he was never paid, for the company got into difficulties; Hansom became its temporary Manager in 1839 and put matters right, for which he was paid £300, all he ever made out of the Hansom Cab. In 1842 he brought out the first issue of The Builder, but lack of capital caused him to retire from the journal. He devoted himself from then on to domestic and ecclesiastical architecture, designing many churches, colleges, convents and schools all over Britain and even in Australia and South America. Of note is St Walburga's church, Preston, Lancashire, whose spire is 306 ft (93 m) high. At various times he was in partnership with his younger brother, his eldest son, and with E.W.Pugin with whom he had a disagreement. He was a Catholic and much of his work was for the Catholic Church.

  • 125 Savery, Thomas

    [br]
    b. c. 1650 probably Shilston, near Modbury, Devonshire, England
    d. c. 15 May 1715 London, England
    [br]
    English inventor of a partially successful steam-driven pump for raising water.
    [br]
    Little is known of the early years of Savery's life and no trace has been found that he served in the Army, so the title "Captain" is thought to refer to some mining appointment, probably in the West of England. He may have been involved in the Glorious Revolution of 1688, for later he was well known to William of Orange. From 1705 to 1714 he was Treasurer for Sick and Wounded Seamen, and in 1714 he was appointed Surveyor of the Water Works at Hampton Court, a post he held until his death the following year. He was interested in mechanical devices; amongst his early contrivances was a clock.
    He was the most prolific inventor of his day, applying for seven patents, including one in 1649, for polishing plate glass which may have been used. His idea for 1697 for propelling ships with paddle-wheels driven by a capstan was a failure, although regarded highly by the King, and was published in his first book, Navigation Improved (1698). He tried to patent a new type of floating mill in 1707, and an idea in 1710 for baking sea coal or other fuel in an oven to make it clean and pure.
    His most famous invention, however, was the one patented in 1698 "for raising water by the impellent force of fire" that Savery said would drain mines or low-lying land, raise water to supply towns or houses, and provide a source of water for turning mills through a water-wheel. Basically it consisted of a receiver which was first filled with steam and then cooled to create a vacuum by having water poured over the outside. The water to be pumped was drawn into the receiver from a lower sump, and then high-pressure steam was readmitted to force the water up a pipe to a higher level. It was demonstrated to the King and the Royal Society and achieved some success, for a few were installed in the London area and a manufactory set up at Salisbury Court in London. He published a book, The Miner's Friend, about his engine in 1702, but although he made considerable improvements, due to excessive fuel consumption and materials which could not withstand the steam pressures involved, no engines were installed in mines as Savery had hoped. His patent was extended in 1699 until 1733 so that it covered the atmospheric engine of Thomas Newcomen who was forced to join Savery and his other partners to construct this much more practical engine.

  • 126 Spooner, Charles Easton

    [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.

  • 127 Webb, Francis William

    [br]
    b. 21 May 1836 Tixall, Staffordshire, England
    d. 4 June 1906 Bournemouth, England
    [br]
    English locomotive engineer who pioneered compound locomotives in Britain and the use of steel for boilers.
    [br]
    Webb was a pupil at Crewe Works, London \& North Western Railway (LNWR), under F. Trevithick (son of Richard Trevithick), and was subsequently placed in charge of the works under Trevithick's successor, J.Ramsbottom. After a brief spell away from the LNWR, Webb returned in 1871 and was made Chief Mechanical Engineer, a post he held until his retirement in 1904.
    Webb's initial designs included the highly successful "Precedent" or "Jumbo" class 2– 4–0, from which the example Hardwicke (now preserved by the National Railway Museum, York) achieved an average speed of 67.2 mph (108.1 km/h) between Crewe and Carlisle in 1895. His 0–6–0 "coal engines" were straightforward and cheap and were built in large numbers. In 1879 Webb, having noted the introduction of compound locomotives in France by J.T.A. Mallet, rebuilt an existing 2–2–2 locomotive as a two-cylinder compound. Then in 1882, seeking fuel economy and the suppression of coupling rods, he produced a compound locomotive to his own design, the 2–2, 2–0 Experiment, in which two outside high-pressure cylinders drove the rear driving-wheels, and a single inside large-diameter low-pressure cylinder drove the front driving-wheels. This was followed by a large number of compound locomotives: three successive classes of 2–2, 2–0s; some 2–2, 2–2s; some 4–4–0s; and some 0–8–0s for goods traffic. Although these were capable of good performance, their overall value was controversial: Webb, who was notoriously autocratic, may never have been fully informed of their defects, and after his retirement most were quickly scrapped. Webb made many other innovations during his career, one of the most important being the construction of boilers from steel rather than wrought iron.
