Capio Yumen LONDON CROSBY LOCKWOOD AND SON, 7, STATIONERS' HALL COURT, LUDGATE HILL. 1901. [All Rights reserved.] PREFACE. THE information contained in the following pages was not originally intended for publication, but represents the contents of an Engineer's note book, collected for use in his own Works during many years of practice. The Author having been in the habit of compiling Rules and Data, relating to his business, for his own use in the practical construction of a great variety of modern engineering work, and having found his notes extremely useful, decided to publish them-after having revised them to date-trusting that a practical work, suited to the daily requirements of modern engineers, would be favourably received by the public. Among many new and original features of this work will be found the following: The weights of those metals usually rolled to gauge are given to the New Imperial Standard Wire-Gauge,-the Birmingham Wire-Gauge being no longer a legal measure. The weights of sheet-iron, hoop-iron, and corrugated iron are those rolled both to the New Imperial Standard WireGauge, and to the B. G. Gauge, or scale adopted by the South Staffordshire Ironmasters, on March 1st, 1884, as the Trade Standard for sheets and hoop-iron. The weights of iron-wire, steel-wire, copper-wire, and brass-wire are to the New Imperial Standard Wire-Gauge. The tables of mixtures of metals, for castings of castiron, gun-metal, brass, antifriction white-metal, and other alloys, are the most extensive and complete ever published. Weights are given of a great number of toothed-wheels, and of pulleys for belts and ropes, also of shafting, couplings, plummer-blocks and many other useful materials. The strengths of materials are based upon the most recent investigations. Particulars are stated of the quantities of work turned out by machine-tools. A Vocabulary of French and English Engineering Terms, which it is believed will be found a useful feature, is added. In order to make the very varied and extensive matter given in this work readily comprehensible by all classes of readers, the use of algebraical symbols has been, with one or two exceptions, dispensed with, the rules being expressed in words—many worked-out examples of which are given and the Author has endeavoured to impart the information as clearly and briefly as possible, and to give nothing but the most recent practical data. PREFACE TO THE SIXTH EDITION. This New Edition has been carefully revised, and greatly improved by the addition of a considerable quantity of new matter. January, 1901. W. S. HUTTON. |
