PREFACE
This book has been written in response to a widespread
demand for a comprehensive work on the machinery,
tools, and methods employed in sheet metal working.
This demand comes from the trade, as well as from
manual-training and technical schools.
Realizing the need for a correlated course in practical
sheet metal and pattern drafting in text form, Professor
J. S. Daugherty, Instructor in Sheet Metal Work in the
School of Applied Industries, Carnegie Institute of Tech-
nology, Pittsburgh, Pa., has rendered valuable assistance
by the preparation of such a course, with pen drawings
and illustrations of actual problems, along the lines of
the best shop methods, derived from years of experience
in teaching the subject and as a practical sheet metal
worker. The course is outlined and the problems are pre-
sented in such sequence that the processes and machine
operations are reviewed with each new problem.
It is not expected that all the problems given by Pro-
fessor Daugherty will be strictly copied, but rather that
they will make clear the methods and processes that may
be applied in the construction of similar problems in
actual practice. The proper sequence, so necessary for
successful instruction in sheet metal pattern drafting, is
an important feature of this course. Many of the prob-
lems are only partly solved, which prevents the student
from copying from the text and compels him to develop
his power to think as well as to draw. It is desired that
this course may be regarded as presenting the essentials
of sheet metal work, rather than as an attempt to produce
a series of models.

6 PREFACE
After a perusal of the correlated course in sheet metal
working and pattern drafting, attention may well be
directed to the chapters in this book on Oxy-Acetylene
Welding and Cutting, Electric Welding, Hand Forging
and Welding, and other information that does not
directly deal with sheet metal work and pattern drafting,
tut includes subjects intimately connected with sheet
metal working practice. These subjects are having exten-
sive introduction in the modern sheet metal shop. Schools
teaching sheet metal working as an industrial art should
therefore in the preparation of their courses, arrange for
lectures that will convey to the mind of the student that
there are other methods for joining together sheet metals
besides riveting and soldering. Any one school term
does not permit extensive practice of these processes,
but the student should know something about them,
to qualify him for a place abreast of his fellow-work-
men on establishing himself in the industrial shop. If
the time for lectures on these subjects is not afforded,
it can be suggested that the student read up on the
same.
The principal author of this book has been for many
years active with The Peck, Stow & Wilcox Co., of South-
ington, Conn., foremost manufacturers of sheet metal
working machinery. He presents a collection of data on
the construction and application of modern sheet metal
working machines and tools, describing their purposes
and uses with pen drawings and other illustrations in as
practical and non-technical a manner as possible, making
the instruction given easy to follow. During eighteen
years of service with the manufacturers named, he has
gained a broad experience in sheet metal working machin-
ery development, and offers here a source of information
of great value to all those interested in sheet metal work,
and the labor and time saving equipment so necessary for
bringing to a finished stage of completion the many
