Theory of Shrinkage and Forced Fits, Machinery's Reference Book No. 89, by William Ledyard Cathcart, originally published by The Industrial Press, New York, NY, 1912. Reprinted by Nation Builder Books, Leesburg, VA, 2006. 5 1/2 x 8 1/2 softcover, 39 pages. Please note that this is a PHOTOCOPIED reproduction of the 1912 original. The accompanying images were scanned from a reprint, not the original. In the early 1900s, when highly skilled machinists enjoyed the same status and prestige as computer programmers do today, Machinery magazine was essential reading for any industrial executive. Industrial Press, the publisher, approached the most erudite master machinists they could find to write a series of booklets on various specific aspects of machining and manufacturing operations. These booklets were jam-packed with the practical knowledge, hard-earned know-how, and "shop kinks" learned over the lifetime of the foremost machinists in the world. In 1914, these booklets were consolidated into the first edition of Machinery's Handbook, which has remained the world's premier handbook for the metalworking trades for nearly a century. A first edition of Machinery's Handbook sold on Ebay in May 2002 for over $200. Another first edition sold in December 2002 for over $300. Until now, many of the booklets that were published as part of the series that was the origin of Machinery's Handbook were almost as rare. Nation Builder Books is proud to begin reproducing a number of these previously rare booklets nearly a century later. The contents are: Introduction Preliminary Considerations Stress—Deformation—Lateral Contraction Elastic Limit—Modulus of Elasticity Shrinkage Stresses – Approximate Method (Tires) Duration and Application of Lame’s Formulas Application of Lame’s Formulas to Compound Cylinders Outer Cylinder Inner Cylinder, Hollow Formulas for Stresses in the Hub Resistance of Hub to Bursting Load Effect of Thickness of Hub on Resistance to Slip Formulas for Stresses in the Shaft Effect of Lateral Contraction Resistance to Slip Shrinkage Allowances Calculating Shrinkage Fits Examples Shrinkage Temperatures Practical Considerations Cylindrical and Tapered Fits Difference Between Forced and Shrinkage Fits Forcing Pressure Applications in Practice From the first page: A shrinkage fit is a cylindrical or slightly conical joint between two machine members, as a crank-web and a shaft, in which the bore of the outer member or crank is smaller than the diameter of the inner member or shaft, so that the outer member must be expanded by heat before It can be set in place, while, in the subsequent cooling, it contracts and grips the inner member with a force which depends on the character of the metals, on the thickness of the outer member, and on the difference between the original diameter of the bore and that of the inner member. This difference is called the allowance for shrinkage. A forced fit is based on the same principle and is virtually of the same character, except that the parts are forced together when cold by hydraulic or other pressure. These fits have a wide range of application, extending from small machine parts to built-up crank-shafts for heavy engines and the massive forgings for high-powered guns.
