Excerpt from The Principles of Iron Founding The object of this work is the elucidation of the principles underlying all of the processes involved in the art of iron founding. The author has himself often felt the need of such a study, for while a number of books on the foundry exist - some very excellent in their way - these are either a collection of data often very poorly digested, or a series of descriptions of methods of operation without giving all the underlying reasons therefor. The author, himself a foundryman, took up this work long after the completion of his University training, and subsequently occupying a chair of engineering at one of the American mining schools. He therefore knew how unsatisfactory any work performed must be to the thinking man if the reasons for so doing are not fully understood. Ever since 1890, therefore, he has worked in the laboratory and at cupola and furnace seeking the why and wherefore of the things that were done and not done. In the course of this scientific and practical experience, the author gained the cooperation and friendship of nearly all the worlds great foundrymen - many of whom are still with us; and his connection with the foundrymen of America, as secretary of their National organization for a seventh of a century has put him rather closely in touch with the numerous and varied problems met within and without the foundry. In all this active - almost frenzied rush of work, the author having made nearly quarter of a million tons of castings in his time - the great need of a thorough understanding of the principles involved in iron founding was ever present, and as so little was definitely known every new problem when fully worked out meant a definite advance. American foundrymen and metallurgists can properly claim the credit for the modern foundry development, and this because the disinterested workers gave the world the benefit of their investigations. The transactions of the foundrymen's associations and the great iron trade journals are still the repositories of this growing fund of information which nevertheless requires discriminating study to separate the kernel from the chaff.

Excerpt from Practical Iron Founding This is an attempt to give a condensed account of the principles and practice of Iron Founding. It is written both for the student and for the practical man. I have stated and explained principles, and Ihave also included the most recent practice, particularly as it relates to the two branches of machine moulding and the melting of iron. My acknowledgments are due to those firms who have placed at my service electros of foundry appliances. About the Publisher Forgotten Books publishes hundreds of thousands of rare and classic books.

Excerpt from Principles of the Manufacture of Iron and Steel: With Some Notes on the Economic Conditions of Their Production I would also express my obligations to Mr. Walter R. Browne, the late Secretary of the Institution of Mechanical Engineers, for his help as the sheets were passing through the press. My son-in-law, Mr. Walter J ohnson, has also afiorded valuable assistance in exam ining many of the statistical figures they contain.

Excerpt from The Manufacture and Properties Iron and Steel Some readers might prefer that less space should be devoted to theoretical matter and more to descriptions of apparatus, but in my Opinion the place for such information is in the trade periodicals. It takes so long to print a book that drawings are antiquated when the issue appears, but the fundamental principles of metallurgy remain the same. A book issued in England refers courteously to the former edition of this work, but states that little information is given concerning the practical details of operation. That 'same book sets forth that an open-hearth furnace is charged by putting the pig-iron in first; that in a. Twenty-five-ton furnace not over nine men can be employed, even when there are doors on both sides, and that with rapid work it takes two hours to charge a heat. Now those figures are true for the district with which that writer was familiar, but in America the pig-iron is put in last, while at Steel ton on a furnace of the size mentioned we use twice the number of men and with good scrap finish the work by charging, by hand labor only, in a period ranging from thirty minutes down to eleven minutes. Of equal value is much of the ao-called practical infor mation given in metallurgical treatises. It only remains to thank many friends, both at home and abroad, for aiding in this work which has been accomplished in the intervals of what I trust is not otherwise an entirely idle life.
