Machine Drawing
From the Preface.
IN issuing this book to the public the Anthers feel that no apology is necessary. They have long felt the want of a book on Machine Drawing which would furnish, at a reasonable price, properly finished and complete drawings of details taken from the most recent practice.
The Authors believe that the best way to encourage the student to make good drawings is to place good ones before him as copies ; and they venture to think that they have succeeded in doing this. The method so often employed in cheap books of requiring the student to draw complete and accurate drawings from incomplete and inaccurate copies is not good; such copies may well serve as tests of knowledge already acquired, but cannot be considered the best means of imparting it. Exercises are given which require the student to test his power of making original drawings, by deducing from the complete views given, others which are not given. The descriptive letterpress, notes and exercises furnished with each drawing, and the perspective illustrations will be found of great assistance for this purpose.
The drawings are not arranged in order of difficulty, since details used for the same purpose, but of different design, are grouped. The teacher should select work suitable to the ability of the student. Drawings for the most elementary, and for the most advanced, are comprised in the following pages.
The proper method of projecting the various views — one from the other — has been adopted in all cases. This is fully explained in the notes to Plate II.
An important feature is the introduction of perspective illustrations of some of the details. These are next in order of value to the use of models. Since the latter cannot be easily obtained, the illustrations form an excellent substitute for them.
In many cases graphic methods are employed to obtain well known proportions of machine parts ; for instance, the method of finding the diameter and pitch of rivets given on Plate IV. may be specially noted.
The Authors desire to express their thanks and indebtedness to several local engineers for their kindness in supplying detailed drawings of some of their products. To Messrs. Kendall & Gent for the lathe details, to Messrs. Smith and Coventry, Ld., for details of the adjustable hanger and Sellers' shaft coupling, and to Messrs. Mather & Piatt, Ld., for the woodcut of engine and dynamo used as frontispiece, and also for details of their piston.
The thanks of the authors are also due to Mr. John Heywood and his staff for the excellent manner in which the book has been produced.
