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

First published in the early 20th century by the McGraw-Hill Book Company, this volume emerged from the technical archives of the widely read American Machinist magazine. It was intended to serve as a comprehensive, practical reference for engineers and machinists working during the rapid expansion of industrial manufacturing. The book sought to distill complex mathematical concepts into simplified formulas, providing shop-floor professionals with reliable guidance on the design and production of gears.

The text was compiled by Charles Hays Logue, who drew upon his extensive experience in gear cutting and machine shop operations to address the technical challenges of the era. By organizing empirical data alongside theoretical tables, Logue aimed to bridge the gap between abstract design principles and the physical realities of commercial gear cutting. Upon its release, it was well-regarded by the engineering community as a essential resource for standardizing gear manufacturing techniques.
