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, the American Machinist Gear Book was born out of the rapid industrial expansion of the era, serving as a vital technical manual for the engineers and machinists powering the rise of precision manufacturing. Charles H. Logue compiled these simplified tables and formulas to bridge the gap between complex theoretical mathematics and the pragmatic, shop-floor demands of gear cutting.

Logue aimed to distill sophisticated engineering principles into a resource that was accessible for the professional machinist, focusing on efficiency and accuracy in the production of commercial gear types. The volume became a staple reference for technical libraries and industrial workshops, respected for its clear instructional approach and its role in standardizing practices during a period when machine tool design was undergoing significant refinement.
