The Involute Gear, Simply Explained, published by The Fellows Gear Shaper Co., Springfield, Vermont, revised edition, 1936 copyrighted in 1930. Reprinted by Nation Builder Books, Leesburg, VA, 2002, 5 1/2 x 8 1/2 softcover, 63 pages. In the early 1900, the Fellows Gear Shapers applied a breakthrough in the mathematical and geometrical understanding of gear design to the problem of cutting gears, making possible mass production of reduction gear devices at relatively low cost. What better explanation of the involute gear can there be, than that given by the Fellows Gear Shaper Co. The sub-title of this little gem reads, ''A direct concise treatise which makes plain the action of involute gearing and yet avoids the use of higher mathematics.” Very well illustrated with crisp line drawings.
