this treatise the author has had as an incitement the knowledge
that there was very little information to be had on the
treatment and working of steel of practical value to the general mechanic. For this reason he is convinced that a practical book
treatment and working of the metal as modern demands
necessitate, that is, in regard to heating, annealing, forging,
hardening and tempering processes, cannot fail to prove of
interest and value to all mechanics who use tools or who are in
any way engaged in the working of metals.
When the fact is
considered that tools made from the best grades of steel will
not perform the work required unless they have been treated
properly during the various heating processes, the value of a
knowledge of the most satisfactory and approved arrangements and
methods to the mechanic is at once apparent.
With the object in
view of giving to practical men a book treating and presenting
this paramount subject in a clear, concise and practical manner,
the author has drawn upon a personal experience of many years,
gathered all the information obtainable, eliminating all
unnecessary and obsolete matter, and added all that is approved,
up-to-date and authentic.
In regard to
originality we lay claim to very little, for, although the facts
contained in a large number of the items have been gained
through years of experience at the forge, bench and machine, we
are indebted to others for a greater portion, and merely claim
to have, as a great poet has said, "gathered the fruits of other
men's labors and bound them with our own string."
technical journals, notably the American Machinist, Machinery,
the Iron Age, the Scientific American, the Age of Steel, Modern
Machinery, and Shop Talk; to master mechanics of well-known
shops, to many American machine-tool and tool and die making
concerns, and to individual fellow craftsmen, the author takes
pleasure in herein acknowledging his indebtedness, with thanks
for a laree number of facts contained in this volume.
writer is aware that his efforts will meet with criticism from
those who may feel that it is not technical enough, or that some
particular process or special method has been ignored, he is
pleased to assure the reader that all that it does contain has
been authenticated, and he is convinced that the majority will
find in its pages information which will assist them in
overcoming trials and difficulties met with in the working of
this "truly wondrous metal."
