entering the profession of mechanical drafting, I was given a
boiler to design. That is to make a working drawing. I had been
taught the principles as to the capacity or size in relation to the
power, the thickness of shell required to resist the strains, and
other such generalities which relate to types and relative economy,
but barely a hint was given me as to the multifarious small details
- which go to make up the difference between work made for sale and
that made for service. In consequence of my lack of knowl- edge, I
was compelled to consult the foreman boiler-maker oftener than I
should. He being as kind as he was experienced, generously gave me
the required information for that boiler. This of course not being
sufficient for my wants, I set about looking for works on the
subject. My disappointment was great, indeed, to find that among
the very few books on the subject, there were absolutely none which
gave the information that I desired. Such as were complete
buriedthemselves over neck and ears in abstruse formulas which ic
is doubtful if the authors could solve after a months absence from
the work, I commenced making notes of any and every thing on the
subject not only the details, but the methods of making them.
Having shownmy notes to a foreman boiler-maker he advised me to
write them out, and have them printed, for it was just such matter
as every boiler-maker wanted. This having been done and shown to
several boiler-makers, further encouragement was given to go ahead.
If any should ask, why the power or capacity and economy of boilers
is not touched upon, I would say that that is strictly in the field
of Engineering, which apparently is well filled, while this book is
entirely devoted to the At thesame time it is to be Workshop. hoped
thatsome engineers, at least those just entering into the workaday
world, may find something that will help them while relieving the
boiler-makers of many disagreeable and difficult constructions.
Again it may be asked why then I introduce strength of materials
and such matters. In answer I would say that nine out of ten
drawings sent to the shop, leave such things entirely to the
boiler-makers, who, more than half of them, have no time to study
Rankine or mathematical science, even were they so disposed. The
endeavor, in this work, is to make it one of ready reference, at
the same time enabling one to work out for himself, in a simple way
such problems as would naturally come up in the course of his daily
work. W. H. FORD. December 23, 1885. I. MATERIALS. Practically,
wrought iron and steel are the only metals used in boilers. Some
few have brass or copper tubes where wood is used for fuel. Copper
fireboxeshave long been discarded in this country. The extra
thickness re- quired for strength as well as to allow for the rapid
deterioration caused by the action of coal gasses more than mak-
ing up for its greater power duction...
