Excerpt from A Text-Book of Elementary Foundry Practice: For the Use of Students in Colleges and Secondary SchoolsIN offering this book to the public, the author would state that upon taking up the work of teaching foundry practice to boys in secondary schools, he was confronted with the great lack of literature on the subject, there being very little of an elementary character suitable for use as a text or a reference work.He has therefore tried to select matter - not too difficult for high school pupils and at the same time sufficiently advanced for the college student - such as will bring out the largest number of principles used in the molder's art, and he has endeavored to make everything so plain 'and practical that even without the direction of an instructor the student can put the patterns into the sand and achieve good results.The patterns chosen may be easily obtained, moreover, as each pattern brings out one or more distinct principles, a student who has completed this course ought to be able, with out further instruction, to produce satisfactory results with any reasonable pattern. Several supplementary exercises should be given to test the grasp of the principles. The author is fully aware that a great deal of work found in ordinary foundries and involving many principles has been omitted, but this has been done only after due consideration of all things involved and discussion with able educators.It is hoped that the ideas herein presented will be of as much value to others engaged in the profession as they have been to the author. He freely acknowledges his indebtedness to various books and periodicals for ideas received therefrom.About the PublisherForgotten Books publishes hundreds of thousands of rare and classic books.
