ARTIFICIAL ICE-MAKING.
An Invention Which Sends n Cold Chin
over the Old leo Companies.

A short time ago this paper gave o
brief notice OF the ice making machine
invented by George W. Stockman, Of
Indianapolis, and recently the reporter,
in company with several prominent bust
ness men, went to Kingan's pork pack
ing establishment to see the machine
at work. The operation Of ice.making,
as conducted by this invention, is OK.
tremely simple and inexpensive. 1t IL
now turning ont Is tons OF ice daily Mt
cost of less than 81 ton, and in large
quantities, the inventor says, it can be
produced as low as fifty cents q ton. No
skilled labor, with the exception Of q
man who has sense enough to keep up O
fire and take care ofan engine and boiler,
is required any place about it. Aqua
ammonia of 30 degrees is put into re-
tort, Which is heated and the vaporized
ammonia passes out through q pipe
which terminates in coil. This coil in
immersed in tank OF water, the effect
of which cooling by tine water is to
liquefy. the ammonia, which then be-
comes pure, or anhydrous. A pipe lead
ing from this liquefying coil connects
with another coil in the refrigerator, in
which is placed, in zinc pans, the water
that is to be frozen.
Between the liqucfying and refrigerat-
ing coils is n cock, which Mt the proper
moment is opened and the ammonia
passes through into the refrigerating
coil, vaporizing and expanding several
hundred volumes and absorbing heat
from everything about it, thus produc-
ing intense cold in the refrigerating
tank, and turning the water in the zinc
pans to ice. After the vapor has done
its work in the reirigerating coil il es-
capcs 10 Ii pipe leading downward into
an absorbcr containing cold water and
terminating in coil. The vapor hay
| ing passed through this coil enters into
and unites with the water in the ab-
sorber, and at that instant it rapidly
parts with the heat it has taken up.
This would quickly heat the absorber
to high temperature and destroy its
efficiency, but Mr.. Stockman compels
the vapor or gas to enter the water at
point close to an outlet pipe connected
with n pump which carries the heated
water, enriched by the gas, away from
| the absorber back to the retort, there to
enrich the weak liquor and be again
yaporized and do its work over and over
again.
The slabs of ice turned out before the
reporters wondering eye were beautiful
to look upon. Each slab was 8 inches
thick by % inches wide and feet long,
weighing $50 pounds. II is frozen at
from 10 to Is degrees above zero, and
pound for pound outlasts natural ice.
| II is the simplest ice machine made and
the cheapest, its first cost being 25 to
80 per cent, less than other machines,
and the wear and tear at least one third
less than on others. The first test was
made at Kingan's, as that is the largest
summer packing g-house in the United
States, and having proved satisfactory,
various improvements were made, and
the work has gone on. The machine
has also been introduced and is in oper.
alton at Atlanta, Ga, and Louisville and
Paducah, Kan.
Mau's brewery, of this city, uses the
same invention, without the ice pans,
for cooling the storage rooms, contain
ing over 10,O00 cubic feet of space, be-
sides cooling 80 barrels Of beer a day.
1t has been in operation continuously
for six months, and is in every way q
success. One important feature is that
the atmosphere is drier than can be pro-
duced by natural ice, which makes q
great saving in cooperage, there being
no molding or rotting The fuel bill Tor
the brewery for the month of July was
$2l9.S5 for all purposes, including thu
cooling machine, while without the ma
chine the cost Of ice necessary for til,
proper cooling of the beer would hav,
been over 81, ,000-showing saving by
reason OF the invention of nearly $500 il
one month. 1t is considered invaluable
at the brewery, rapidly reducing the
temperature of the beer rs il comes from
the surface cooler at $50 degrees, which
must be brought down before it can be
stored.
