Mr.. John MacFarlane Has Invented
Great Boiler Cleaner,


Great Boiler Cieane

world that wonderful product OF his tod

greatest Contrivance which has ever been
perfected III many years by a Washington
man is the patert steam boiler cleaner of
John MaCFariane, a young engineer, the
possibilities of whose machine are un-
! limited, and whose good cannot be over
rated.
The great curse OF commerce for many
years has been foli u i!c-s-a6. L. :. iueral
sense, but in the tickle manner i'll which
sion.
This is caused by two reasons. prima-
~ one the water used and secoDdarily, the
lack of some suitable arrangement for
purifying it so as TO make il proper for
use.
1t IS 4 wcll-known fact that in all water
there are certain mineral, ingredients whose
presence is most harmful to metal, namely.
the chlordcs and sulphates of magnesium
and sodium, along with common mud
and sand and the oxides OF iron and alum
mum.
When the water is taken into the boilers
it is 10 all appearances clear, but as soon
as it becomes heated these substances sep
arate and rise 10 the surface in the form
OF 4 thick scum. Here this is retained by
the heat currents until night, when the
steam having subsided, some desceuds TO
the bottom and the rest cllugs 10 the valves
and pipes. This process being repeated
daily, at the end of week there is i
hard crustaceous formation on the boilers
interior, non-2onductiyc of heat and yery
dangerous. -.,....
OF course this on-conductivenesS re.
quircs Il greater quantity OF fuel to be used
10 raise the requisite amount of steam. And
when one reflects that ton day is not
an unusual amount of coal in even u fair
sized engine room. the unnecessary waste
may easily be realized 10 assume formid-
able proportions in years time. Bat,
however, il is necessary that this incruS-
tation bc removed, once n month at least.
which operation can only be accomplished
by chipping" This is nothing less than
the term implics-a knocking off of the
boiler crIst by Il hammer and chisel, task
which is both slow and laborious and which
entails fun stoppage OF the machinery for
several days.
If this removal nc not made on time the
boilers belly or part which receives the
heat, becomes burnt out" and when
pressure of steam is applied. being
unable To withstand the force, naturally the
boiler explodes. -.-.a.
This is the cause of so many steamboat
eXpIosiOns-the water which is used being
taken on more thickly mixed with mud than
that ordinarily in service.
Some engineers cndeavor TO clean their
boilers by "hoiler compound hut any
sensible man realizes that acids which will
