An experience of seventeen years in teaching pattern-making and
kindered subjects has made me feel the great need of such a work
as this which I now offer as a text-book for students in
technical and manual training schools, and universities.
number of excellent books on the subject have been published, to
be sure, but most of them assume on their reader's part previous
acquaintance with the fundamental ideas of pattern - making;
such as do treat at all of the elementary part of the subject,
happen to be works of an exhaustive character, which are
consequently too expensive for use as text-books.
The present work, therefore, will, it is hoped,
find a field of usefulness for itself.
It is of course to be recognized that as
pattern-making is an art, it cannot be learned simply by reading
any book on the subject; but only by practice. Still a textbook
may afford valuable assistance even to the artisan.
This work, however, has a further and more
important purpose,—that of imparting to the engineer or the
draftsman the fundamental principles of pattern-making. For only
as he is in possession of these can he make designs for patterns
in accordance with which shop work can be performed in the most
efficient and most economical manner.
The reader should also understand that this
work, being designed only as an elementary treatise, in no way
exhausts the subject. It is claimed however, that the examples
of pattern-making submitted indicate, on the whole, the best
methods of construction and those most easily understood by the
In preparing the body of this work, I have
received many valuable suggestions which have been incorporated
herewith, and which will have contributed to any success the
book may attain. The works of many previous writers on the
subject have been consulted also; for specific ideas derived
from them credit should be given to Joshua Rose, M. E., J. McKim
Chase, and P. S. Dingey.
In preparing the appendix considerable help was
afforded me by the little book of W. F. M. Goss, on "Bench Work
in Wood." With these few words of introduction, I leave the book
to its readers with the hope that it will assist them to master
the important subject of which it treats.
