PREFACE
Many engineering departments, perhaps most, compile and keep up to date a
manual which may be called the standards book, reference book, engineering depart-
ment standards, or which may be given some other name. Also, many design
engineers build their own book or manual. In such books will be found a vast fund
of engineering data and many methods of design procedure not found in existing
handbooks.
When Product Engineering was launched as a pubhcation to serve the design
engineers, it was obvious to the editors that a great service could be rendered to the
profession by gathering and publishing data, information, and design procedures such
as are contained in engineering department manuals. Thus, the first number of
Product Engineering in January, 1930, contained a reference-book sheet for design
calculations, a feature which has been continued in practically every number. Soon
afterward, there was added to Product Engineering's editorial content anotherregular
feature, a two-page spread illustrating standard constructions, possible variations by
which to achieve a desired result, and similar design standards covering constructions,
drives, and controls.
It was soon found impossible to meet all the requests for additional copies of
reference-book sheets and design standards. The demand continued to increase and
numerous readers suggested that the material be compiled into book form and pub-
lished. It was in answer to this demand that the authors compiled this book.
Other than the major portion of the chapter on materials and a few other pages
that have been added to round out the treatment of certain subjects, all the material
in this book appeared in past numbers ofProduct Engineering, although some of it has
been condensed or re-edited. Very little of the material in this book can be found in
the conventional handbooks, for this Handbook of Mechanical Design contains practi-
cally no explanations of theoretical design. It confines itself to practical design
methods and procedures that have been in use in engineering design departments.
The authors wiU welcome suggestions from users of this book and especially
desire to be notified of any errors.
We wish to make special acknowledgment of the material on typical designs
appearing in Chapters IV and VI, by Fred Firnhaber, now of Landis Tool Company;
the nomograms by Carl P. Nachod, vice-president of the Nachod & U. S. Signal Co.;
the standard procedure in the design of springs by W. M. Griffith of Atlas Imperial
Diesel Engine Company; the spring charts by F. Franz; the methods for calculating
belt drives and other nomograms by Emory N. Kemler, now associate professor of
mechanical engineering at Purdue University; the nomograms for engineering calcu-
lations by M. G. Van Voorhis, now on the editorial staff of Product Engineering; and
to S. A. Kilpatrick and 0. J. Schaefer for their brilliant series of articles, which have

alloy sections. Acknowledgment is also made here of data on properties of materials
contributed by the Alimiinum Company of America, United States Steel Corporation,
and the American Foundrymen's Association.
Other engineers whose contributions to Product Engineering have been incorpo-
rated in this book are H. M. Brayton, 0. E. Brown, E. Cowan, C. Donaldson, R. G. N.
