Locomotive breakdowns, emergencies and their remedies; an up-to date catechism - An up-to-date catechism treating on accidents and break-. downs on the road and how to repair them. Every kind of an accident which is likely to occur to a locomotive, including engines of the most modem type, is fully considered and the remedy given in plain language, and, in most cases, clearly illustrated. The Wal-, schaert valve gear is included with special reference to each - individual piece of the mechanism, as is also the locomotive electric head light, and a full course of instructions on air-brake defects, troubles and errors in up-to-date operation, are given. The several styles of-compound locomotives are included. Contains over 400 Questions with their Answers By GEO. L. FOWLER t Revised and enlarged by WM. W. WOOD, Air-brake Inspector - 1908 - PREFACE TO FIFTH REVISED AND ENLARGED EDITION. his collection of remedies for emergency locomotive work is not original and newly devised by the author, or it would not be applicable to presently existing conditions and circumstances. The value of technical-instruction books is in the fact that they represent thz resdts of practical application and tests of theories, and in compiling this work the only originality involved has been in connection with the revision of the present edition authorities differ as to the best methods of dealing with certain troubles, and this book presents the latest ideas on those subjects, embodying the methods pursued by practical enginemen, and indorsed and recommended by the Travelling Engineers and Master Mechanics. Emergency measures that a few years ago were universally advised in cases of breakdown are found to be impractical with the extremely heavy engines of the present day, and in this revision the author has sacrificed some of the really preferable methods that were for years unquestioned as the proper remedies in cases of road troubles and still required by some authorjties, to the present-day principle of the least road repair compatible with safety, in order that an accident may not develop into an engine failure as determined by time delayed, and that the engine can get a paying load under way as soon as possible. As this book is intended for the benefit of every one in any way connected with the locomotive, the chgpter on Engine Repairs is the premium to the Shop and Roundhouse men, illustrating a number of handy devices used in locomotive shop repairs, and, while not coming within the limit of road emergencies, may be considered valuable when time is an important element that demands instant recourse to the quickest means of effecting what practically amounts to emergency repairs. With the expansion of the Air-Brake chapter, and the added features of the Walschaerts Valve Gear and the Electric Headlight, the author and the publishers are exceedingly satisfied - with this revised edition, and believe that it is exactly what locomotive enginemen need and want they all know what to do when the engine is all right, and this book will enable them to know what to do when the engine is all wrong-and we dont believe that very much of importance has escaped the present edition.
