diameter OF the drum for the purpose Of
giving plenty Of steam room, and in sucf
that the bubbles Of steam shall have 4
chance to rise and disengage without car
rying the water with them.
IL, on looking into the furnace or fire-box,
you see depression in the crown-sheet
that is, a bulging down from above, that IL
a sign that the mud or scale above the spot
thus depressed has prevented the water
from carrying on the heat of the hre, and
has thus allowed the sheet to get red hot,
aud to come down by reason Of the
pressure.
| What has happened once may happen
again The same spot may get heated and
come down, all the way, and IL such thing
happened, the community would know OF
II. Sometimes the hot spots come down
all the way the first time.
III on going into the boiler and rapping
the braces (supposing there are rod braces)
any OF them
SOUND LOOSE AND RATrLY,
that is a sign that they have stretched or
that the surfaces which they connect have
stretched, or that adjacent surfaces have
moved out OF place. 1t usually shows that
there is undue strain on the adjacent
stays; and the loose ones should be tight
ened up so that the stress shall be divided
up evenly, as originally intended.
say ION going into the boiler" Iassume
that you take enough interest either to in
yourself once in awhile, or to see 20 it that
someone thoroughly in your confidence
goes in for you and reports to you
independently Of your engine runner
or fireman. Ex-Msyor Cooper, Of New
Y DIRK. millionaire ana a member of "the
four hundred" goes into his boilers, lamp
IN hand, aud sees for himself that things
are right. No one ever accused him of do
ing anything for effect; and think that he
IS rather inclined to taking things easy
and to have things as neat and nice about
him as he can. But when it comes to the
boilers he wants to know about them him
self; particularly about
THEIR INSIDE CONDITION.
Too much hangs on that to leave it to a
deputy, no matter how capable, no matter
how competent
IL the finger Of your steam -guage vi
brates with each stroke OF your engine,
that is usually sign that there is not
enough steam room. 1t may indicate very
sharp cutoff at the engine, but there Is
nothing dangerous or undesirable about
that.
IL on looking into the combustion cham
Der you see blue flames streaming from
cracks in the brick work, that is usually
sign that excess Of air is getting st the
fire from above, rather than coming
through the CRATE as all air should come,
If possible.
II is in this usually q sign of waste Of
fuel and lessened steaming capacity; but
independently Of this it shows that the
prick work is in bad condition; and when
you find that out you should take the first
opportunity Of inspecting and the first OF
repairing il.
if you find the boiler blowing off one
minute aud steam running down the next,
it is sign that you have
NOT ENOUGH BOILER CAPACITY
or that the demands of your establishment
for steam are too Irregular and capricious,
or that the fuel is bad, or that the fireman
is incompetent. All these may be the case.
If you lind the plates scared at the seams
by the caulking- tool, it is sign that some
day you may have a first class private ex-
plosion.
If the fireman heaps coal on the middle
of the CRATE of q boiler of the locomotive
type and leaves uncovered spaces next the
water leg, it is sign that he ought to be
discharged as Incompetent; that II the
practice is continued there will be cracked
nre-Dox some day where the cold air from
the ash pit strikes the hot plates This Is
particularly the case where the fire box is
of steel

If PLATE RINGS CLEAR
and sharp under the hammer, il is q sign
that it is in good CO ndition. considered as q
plate. IL it sounds dead and fat it is
sign of burning, or of cracking, or OF its
being cal1ed thick with mud or scale.
II your gauge glass is half filled with
sediment it is a sign first, that the feed
water is foul, and second, that the glass
should be taken out and swabbed, and the
passages in the fitting bored out, clean and
full size, by a steel rod. Otherwise your
gauge glass will become utterly useless, !
and lying gauge is worse than none at all. |
