MUIRHEAD, Richard, M.I.Mech.E., Consulting Engineer, 66, Parrock Street, Gravesend. T. A.: Muirhead, Gravesend." Is descended from a very old Scottish family, long settled in the south of Scotland. Was articled to the late Edward Hayes, senr., of the Watling Works, Stony Stratford, and while there became greatly interested in the steam carriages, designed and built by Thomas Rickett, of the Castle Foundry, Buckingham, for the then Duke of Sutherland, the Earl of Caithness and others. After completing his " time," he went to the great 'railway works of the L. and N.W. Railway at Wolverton, where locomotives were then built. Then, in .order to get an insight into marine engines, he obtained an appointment with the late well-known firm of John Penn and Son, Greenwich. His next position -was that of Engineering Instructor and Demonstrator of Mechanics at Farnah Hall Training College for .engineers, near Derby. While there he experimented for several years with steam carriages and succeeded in conveying ten passengers at a good speed over the loose gravelly private roads in the park, the law in those days (1868-9-70) prohibiting the use of public roads for that purpose. The results achieved and the experience gained by these experiments, 26 however, attracted the attention of the Government of India, where no such restrictive law existed, and this led to his being appointed Engineer and Assistant Superintendent of the Government Steam Road Train Service then being organized by Lieutenant (now Colonel) Crompton, C.B., etc., the engines of which, called " road steamers," ran on solid india-rubber tyres invented by the late R. W. Thomson, C.E., of Edinburgh. On the completion of this service he returned to England and went into business as a manufacturing engineer, after 21 years of which he commenced practice as a Consulting Engineer, in which capacity he has been again employed by Government on several occasions. He is also a versatile inventor and has obtained many patents which cover a great variety of subjects. He was one of the original founders of the Royal Automobile Club, and being one of the earliest living pioneers of Automobilism is recognized as an authority on all matters concerning that movement, especially as regards the use of steam engines and elastic tyres for the heaviest class of vehicles.
