Excerpt from American Machinist Gear Book: Simplified Tables and Formulas for Designing This book has been written to fill a pressing want; to give practical data for cutting, molding, and designing all commercial types, and to present these subjects in the plainest possible manner by the use of simple rules, diagrams, and tables arranged for ready reference. In other words, to make it a book for "the man behind the machine," who, when he desires information on a subject, wants it accurate and wants it quick, without dropping his work to make a general study of the subject. At the same time a general outline of the underlying principles is given for the student, who desires to know not only how it is made, but what is made. Controversies and doubtful theories are avoided. Tables and formulas commonly accepted are given without comment. A great deal of this matter has previously been published in the columns of the American Machinist, but is revised to make the subject more complete. Credit is given in all cases when the author is known; there may be cases however, where record of the original source of information has been lost, as is often the case when data are in daily use and the authority is obscure. Obviously in such cases the author's name cannot be given. About the Publisher Forgotten Books publishes hundreds of thousands of rare and classic books.

Excerpt from American Machinist Gear Book: Simplified Tables and Formulas for Designing The continued demand for a work on gearing along lines as originally planned by Charles H. Logue in 1910 has been so persistent that it has been deemed advisable to enlarge and revise the previous edition Of the American M ackinist Gear Book rather than to publish at the present time a new book on practical gear design and methods of production. In doing so, parts of the original work which are no longer of particular value to the practical man have been omitted and other parts revised to bring the work up to date. The chief additions have consisted of sections devoted to varieties Of bevel gears which have demonstrated their commercial value during the past few years spiral type bevel gears and bevels of the Williams master form variety; to an exposition Of the Williams System of Internal Gearing; and to the first presentation in book form Of the successful development of the rolling process of gear production.
