"THE LATE MR. JOHN MITCHELL.
The news of the sudden death, in a nursing home, of Mr. John Mitchell, on October 20, will be received with regret by many railway engineers. Mr. Mitchell, who had been managing director of Messrs. A.B.C. Coupler and Engineering Company, Limited, since May, 1918, was the son of the late Mr. Hugh Mitchell, M.I.Mech.E., of Edinburgh. He was born at Kadu-ganawa, Ceylon, on December 24, 1874, and received his early scholastic training by private tuition at Colombo. In 1885, he was sent to this country and completed his general education at Daniel Stewart’s College, Edinburgh. From 1891 to 1896 he served his time in the running sheds and workshops of the Caledonian Railway Company, first at Edinburgh and subsequently at St. Rollox, Glasgow. Meanwhile, he received scientific training at the Heriot-Watt Technical College, Edinburgh, and at the Glasgow and West of Scotland Technical College, Glasgow. Upon concluding his apprenticeship, he was engaged as draughtsman in the works of the Caledonian Railway Company, but, in 1897, was appointed to take charge of the testing and inspection departments of the Company at St. Rollox. In addition to research work in connection with firebox stays and plates, tubes, springs, oils and boiler incrustation, he supervised the construction of six express passenger locomotives, of the Dunalastair type, at Messrs. Neilson Reid’s works, for the Belgian State Railways.
Mr. Mitchell joined the staff of Sir Alexander M. Rendel, K.C.I.E., in 1899, his duties consisting of the supervision, during manufacture, of the railway material made for the Indian State and other railways, by the principal steel and engineering firms in Sheffield and district. In 1900, he was promoted to the headquarters staff, at Westminster, of Sir Alexander Rendel. He was first assistant in the rolling-stock department and afterwards acted as engineering assistant to Sir Seymour B. Tritton. In 1904, Mr. Mitchell became advisory engineer to the Cape of Good Hope Government, a position he continued to occupy for the succeeding seven years. In 1911, he was appointed engineer to Messrs. A.B.C. Coupler, Limited, London, and, in May, 1918, managing director of the Company, which is now known as Messrs. A.B.C. Coupler and Engineering Company, Limited, 31, Queen Anne’s-gate, London, S.W.l. Mr. Mitchell has been responsible for the introduction of a number of automatic railway couplers, buffers, wagon doors and other devices.
