American Machinist Gear Book: Simplified Tables and Formulas for Designing, and Practical Points in Cutting All Commercial Types of Gears

First published in 1910 by the McGraw-Hill Book Company, this volume emerged from the pages of the influential trade publication American Machinist. Written by Charles Hays Logue, the book was intended to serve as a definitive technical reference for mechanical engineers and machinists during an era of rapid industrial expansion, providing a systematic approach to the complex geometry and mathematics required for gear design.

The text was meticulously compiled to bridge the gap between abstract theoretical calculations and the practical constraints of the workshop floor. Logue emphasized the importance of standardized tables and direct formulas, aiming to streamline the production of spur, bevel, worm, and spiral gears. Its widespread adoption by trade schools and drafting rooms solidified its reputation as a pragmatic guide for those navigating the evolving standards of early twentieth-century mechanical engineering.
