I Gentlemen
Replying 10 your letter of
NprH eth there are two very
\ important factors that must be
considered IN the manufacture
Of -efrigerators. one is the cir
I cuidtion and the other is the N
sLlation. Tie construction Of 4
refrigerator is made up of de
tails that are worked out from
years Of experience. There are
a number of good insulators
known and in use today 1t is
not SO much the insulator you
use as it is the way YOU use it.
Mineral wool. felt. charcoal.
charcoal sheathing. graduated
wool. rock wool. cotton, seaweed.
granUlated cork. cork shavings
and numerous other insulators
are known 10 the manufacturer
of refrigerators. II is fact
that the best insulator known
To science today is vacuum but
IL is not practicable To use
vacuum. The next best in
sulator known to science is con-
fined air or air cells If it were
possible To- build a refrigerator
with small compartments, and
confine the air. so that it could
J.,
best insulator that we could
find that would b. practical to
use. In the past we have used
great deal of charcoal when
We could arrange to buy this
We use a large quantity of il,
buying it in carloads, but some
times we are compelled 10 use
some other insulating material.
We have made numerous tests,
both scientific and comparative.
and we find that there is very
little difference in a number Of
the best insulators. The secret
of all insulation is the confined
air that is in the cells af The
various material that We use,
and the success of the insIla-
tor depends largely upon the
method used in handling these
various insulating materials.
The insulation of refrigerator
is similar To the strength Of a
chain. 1t is only equal 10 the
weakest part, hence great care
is necessary in using insulating
materials in a refrigerator No J
doubt you viii hear different
manufacturers claim great re-
suits from the particular mattel
ial that they use in Insulating
their refrigerators. We will be
candid with you, and state that
most any Of the materials that
we mentioned above will produce
good results. if it is properly
used
We have always advocated
charcoal. and we think a great
deal of il as an insulating ma
terial. provided the construction
of the refrigerator is such that
il viii not settle That is onc
Of the strong points that We
make i'm our construction, ;hat
the material we use does not
settle
In our experience We have
been successful in using these
several materials, and 10 not
hesitate to say that il is not \
necessary To condemn any of the \
materials used for insulating re- \
frigerators. They are all good. \
and when properly used. will
show very little difference in the
results. We have always IA
vored charcoal perhaps more
than any other material, but
some of our larger customers
prefer other insulating material.
We are sending you via L. ;.
Express today a sectional corner
Of the Alaska line. which posi-
bly, may not exactly represent
our 1911 goods. but will enable
you To demonstrate the con-
struction OF the refrigerators TO
better advantage, than without
the use of it.
We appreciate very much the
interest you take in the Alaska
product. and therefore are will
ing to help you all we can to
increase your sale on refrigera-
tors.
Yours truly,
