A Manual of Machine Drawing and Design (Classic Reprint)

In this work the authors have attempted to provide: (1.) A large number of dimensioned illustrations which may serve as good drawing examples for students, examples ranging in difficulty from the simplest machine detail to a set of triple-expansion marine engines. (2.) Illustrations and descriptions of a great variety of machine details, which may assist the designer in selecting the form of detail best suited to his (purpose. (3.) Many rules and tables of proportions, based on scientific principles or on numerous examples from actual practice, which may be useful to the experienced designer for the sake of comparison with the results of his own practice, and which may, to some extent at least, take the place of the well-filled notebook and collection of designs usually possessed by the experienced designer, but which the young :k engineer or draughtsman can scarcely be expected to have. (4.) Nume rous examples showing the application of the principles of mechanics to the calculation of the proportions of parts of machines. The illustrations given are very numerous, and they have aU been specially prepared for this work from working drawings, and the authors 5have been at great trouble to obtain examples representing the best modern practice in machine design. The authors would here acknowledge their great indebtedness to the many engineers and engineering firms throughout the country who have generously given them drawings and much valuable information, which they feel sure will prove useful to students, draughtsmen, and engineers. They would also record their indebtedness to the leading engineering papers, and to the published Proceedings of the various engineering societies, English and A merican, for particulars of examples of modern practice, which they have either incorporated directly, or have made use of in drawing up the numerous rules and tables wh
