WHILE there is little a foundryman needs to know which has not been fully treated by competent authorities, there is not, so far as I am aware, any summary of this great mass of publications.
In a foundry experience covering many years, I have frequently spent hours at a time in searching for special information. Believing, therefore, that a compilation of this matter, with authoritative instruction for the solution of the many problems which are continually presented in the foundry, all properly arranged for ready reference, would receive a favorable reception, an attempt
a has been made to meet this need by the production of this book.
The material for the Manual has been drawn from every
available source. The proceedings of the American Foundrymen's Association have furnished no end of information. The publications of Professors Turner, Porter, Reis, Dr. Moldenke, Messrs. Keep, Longmuir, Outerbridge, West and others have been most carefully searched. Much has been taken from “ The Foundry,"
Castings ” and “Iron Age.” A great many of the
Possibly, in some cases, special credit for extracts has not been accorded; for such omissions indulgence is asked, as there has been no intentional neglect or lack of courtesy.
In the selection of the material for the book, proper consideration has been taken of beginners and others who may have not gotten very far in their acquisition of foundry information. For such men, it is also hoped the book will be of good service.
As regards the price lists and discounts which are given in connection with many foundry supplies, it should be stated that these are not quoted as current prices. They are offered simply as furnishing a guide to close approximation of costs.
The matter for the preliminary portion of the book relating to elementary Mathematics, Mechanics, etc., has been taken in large part from such authorities as Rankine, Bartlett, Wentworth, Trautwine, Kent, Jones and Laughlin, Carnegie Steel Co., and the Encyclopedia Britannica.
