The Joy valve gear, generally used in England, … Service Sheet 04 Slip-eccentric Valve Gear Valve timing adjustment on early Roundhouse locomotives. Joy's valve-gear was used extensively on Lancashire and Yorkshire Railway and London and North Western Railway locomotives, and also on the Manning Wardle-built narrow gauge 2-6-2 locomotives of the Lynton and Barnstaple Railway. DESIGN AND INVENTION - 13 THE Stephenson, Allan, and Gooch link motions required four eccentrics on the driving axle, as explained in the chapter “Locomotive Valve Gears”.With inside-cylinder engines this requirement restricted the thickness of the crank webs - a serious matter as the engines increased in size. Folder. The Control of Steam in a Railway Engine. Amen!”—Robert Burns (1759–1796), ““Though logic-choppers rule the town,And every man and maid and boyHas marked a distant object down,An aimless joy is a pure joy....””—William Butler Yeats (1865–1939).

Joy's gear is similar to Hackworth valve gear but has a compensating mechanism which corrects for "the slight inequality in the motion of the valve arising from the arc of the lever". Joy valve gear is a type of steam locomotive valve gear, designed by David Joy (1825–1903), Locomotive and Marine engineer, and patented in 1870. [2] Joy's gear is similar to Hackworth valve gear but has a compensating mechanism which corrects for "the slight inequality in the motion of the valve arising from the arc of the lever".[3]. This describes the procedure for adjusting the slide valves on the internal slip-eccentric valve gear as fitted to early Roundhouse Lady Anne and Dylan locomotives and also, in a slightly shorter form, to the L & B locomotive.
