16 Saxby, John
[br]b. 17 August 1821 Hurstpierpoint, Sussex, Englandd. 22 April 1913 Hassocks, Sussex, England[br]English railway signal engineer, pioneer of interlocking.[br]In the mid-1850s Saxby was a foreman in the Brighton Works of the London Brighton \& South Coast Railway, where he had no doubt become familiar with construction of semaphore signals of the type invented by C.H. Gregory; the London-Brighton line was one of the first over which these were installed. In the 1850s points and signals were usually worked independently, and it was to eliminate the risk of accident from conflicting points and signal positions that Saxby in 1856 patented an arrangement by which related points and signals would be operated simultaneously by a single lever.Others were concerned with the same problem. In 1855 Vignier, an employee of the Western Railway of France, had made an interlocking apparatus for junctions, and in 1859 Austin Chambers, who worked for the North London Railway, installed at Kentish Town Junction an interlocking lever frame in which a movement that depended upon another could not even commence until the earlier one was completed. He patented it early in 1860; Saxby patented his own version of such an apparatus later the same year. In 1863 Saxby left the London Brighton \& South Coast Railway to enter into a partnership with J.S.Farmer and established Saxby \& Farmer's railway signalling works at Kilburn, London. The firm manufactured, installed and maintained signalling equipment for many prominent railway companies. Its interlocking frames made possible installation of complex track layouts at increasingly busy London termini possible.In 1867 Saxby \& Farmer purchased Chambers's patent of 1860, Later developments by the firm included effective interlocking actuated by lifting a lever's catch handle, rather than by the lever itself (1871), and an improved locking frame known as the "gridiron" (1874). This was eventually superseded by tappet interlocking, which had been invented by James Deakin of the rival firm Stevens \& Co. in 1870 but for which patent protection had been lost through non-renewal.Saxby \& Farmer's equipment was also much used on the European continent, in India and in the USA, to which it introduced interlocking. A second manufacturing works was set up in 1878 at Creil (Oise), France, and when the partnership terminated in 1888 Saxby moved to Creil and managed the works himself until he retired to Sussex in 1900.[br]Bibliography1856, British patent no. 1,479 (simultaneous operation of points and signals). 1860, British patent no. 31 (a true interlocking mechanism).1867, jointly with Farmer, British patent no. 538 (improvements to the interlocking mechanism patented in 1860).1870, jointly with Farmer, British patent no. 569 (the facing point lock by plunger bolt).1871, jointly with Farmer, British patent no. 1,601 (catch-handle actuated interlocking) 1874, jointly with Farmer, British patent no. 294 (gridiron frame).Further ReadingWestinghouse Brake and Signal Company, 1956, John Saxby (1821–1913) and His Part in the Development of Interlocking and of the Signalling Industry, London (published to mark the centenary of the 1856 patent).PJGR -
17 Gregory, Sir Charles Hutton
[br]b. 14 October 1817 Woolwich, Englandd. 10 January 1898 London, England[br]English civil engineer, inventor of the railway semaphore signal.[br]Gregory's father was Professor of Mathematics at the Royal Military Academy, Woolwich.C.H. Gregory himself, after working for Robert Stephenson, was appointed Engineer to the London \& Croydon Railway in 1839. On it, at New Cross in 1841, he installed a semaphore signal derived from signalling apparatus used by the Royal Navy; two hinged semaphore arms projected either side from the top of a post, signalling to drivers of trains in each direction of travel. In horizontal position each arm signified "danger", an arm inclined at 45° meant "caution" and the vertical position, in which the arms disappeared within a slot in the post, meant "all right". Gregory's signal was the forerunner of semaphore signals adopted on railways worldwide. In 1843 Gregory invented the stirrup frame: signal arms were connected to stirrups that were pushed down by the signalman's foot in order to operate them, while the points were operated by levers. The stirrups were connected together to prevent conflicting signals from being shown. This was a predecessor of interlocking. In 1846 Gregory became Engineer to the Bristol \& Exeter Railway, where in 1848 he co-operated with W.B. Adams in the development and operation of the first self-propelled railcar. He later did civil engineering work in Italy and France, was Engineer to the Somerset Central and Dorset Central railways and became Consulting Engineer for the government railways in Ceylon (now Sri Lanka), Cape of Good Hope, Straits Settlements and Trinidad.[br]Principal Honours and DistinctionsCompanion of the Order of St Michael and St George 1876.

19 Knight, John Peake
[br]b. 1828d. 1886[br]English railway engineer, inventor of the first road traffic lights in Britain.[br]Knight was initially employed as a clerk at the Midland Railway in Derby, and in 1846 he had a job in the audit office of the Brighton Railway. From 1854 to 1869 he was Superintendent of the South Eastern Railway and then became manager of the London, Brighton and South Coast Railway, a post he held until his death. During this period many improvements were put in hand, including the interlocking of signals, the block system, the incorporation of Westinghouse brakes (in 1878), Pullman cars (1877) and electric lighting.In 1868 it was decided to erect the first set of traffic lights in London in Bridge Street, New Palace Yard, Westminster, and the authorities naturally sought the advice of an engineer familiar with railway practice. Thus John Knight was called in, and red and green lights mounted on the ends of semaphore arms were duly installed. Unfortunately, a fault in the gas supply of this set of lights caused an explosion which killed a police constable.[br]Principal Honours and DistinctionsLieutenant-Colonel, Engineer and Railway Volunteer Staff Corps 1870–86.

20 Westinghouse, George
[br]b. 6 October 1846 Central Bridge, New York, USAd. 12 March 1914 New York, New York, USA[br]American inventor and entrepreneur, pioneer of air brakes for railways and alternating-current distribution of electricity.[br]George Westinghouse's father was an ingenious manufacturer of agricultural implements; the son, after a spell in the Union Army during the Civil War, and subsequently in the Navy as an engineer, went to work for his father. He invented a rotary steam engine, which proved impracticable; a rerailing device for railway rolling stock in 1865; and a cast-steel frog for railway points, with longer life than the cast-iron frogs then used, in 1868–9. During the same period Westinghouse, like many other inventors, was considering how best to meet the evident need for a continuous brake for trains, i.e. one by which the driver could apply the brakes on all vehicles in a train simultaneously instead of relying on brakesmen on individual vehicles. By chance he encountered a magazine article about the construction of the Mont Cenis Tunnel, with a description of the pneumatic tools invented for it, and from this it occurred to him that compressed air might be used to operate the brakes along a train.The first prototype was ready in 1869 and the Westinghouse Air Brake Company was set up to manufacture it. However, despite impressive demonstration of the brake's powers when it saved the test train from otherwise certain collision with a horse-drawn dray on a level crossing, railways were at first slow to adopt it. Then in 1872 Westinghouse added to it the triple valve, which enabled the train pipe to charge reservoirs beneath each vehicle, from which the compressed air would apply the brakes when pressure in the train pipe was reduced. This meant that the brake was now automatic: if a train became divided, the brakes on both parts would be applied. From then on, more and more American railways adopted the Westinghouse brake and the Railroad Safety Appliance Act of 1893 made air brakes compulsory in the USA. Air brakes were also adopted in most other parts of the world, although only a minority of British railway companies took them up, the remainder, with insular reluctance, preferring the less effective vacuum brake.From 1880 Westinghouse was purchasing patents relating to means of interlocking railway signals and points; he combined them with his own inventions to produce a complete signalling system. The first really practical power signalling scheme, installed in the USA by Westinghouse in 1884, was operated pneumatically, but the development of railway signalling required an awareness of the powers of electricity, and it was probably this that first led Westinghouse to become interested in electrical processes and inventions. The Westinghouse Electric Company was formed in 1886: it pioneered the use of electricity distribution systems using high-voltage single-phase alternating current, which it developed from European practice. Initially this was violently opposed by established operators of direct-current distribution systems, but eventually the use of alternating current became widespread.[br]Principal Honours and DistinctionsLégion d'honneur.
