GkEAT MACHINE EINVENTED
An Apparatus for Cooling the
Atmosphere In DWELLINGS,.

| All apparatus Tor Cooling the
Atmosphere In Dwellings.
| Prof. Willis l.. Moore, chief of the
Weather Bureau at Washington, has
perfected very valuable machine
which should make the hottest sum,
mer eRdurable in tho most torrld
cline. 1t is All apparatus for cooling
the atmosphere in houses and 1t may
be used for commercial purposes as
cold storage plant. The machine is
| described i'll a dispatch from Wash.
ington to the New York Sun as fol.

The gravity apparatus for cooling
dwellings, invented by Prof. Willis l..
Moore, chief of the Weather Bureau,
patents for which were recently SO.
cured, was placed in operation for pub.
lie demonstration today. The machine
looks like cylinder stove, and the in
ventor says it will in time come to be
considered as essential to the comfort
of dwelling IN summer as heating ap.
paratus in winter. Prof. Moore saws
that the cost of cooling given space
with tins machine is approximately the
Same as that Of heating the same space
by means of stove or furnace. Be-
sides this, the different uses to which
the machine may be put are unlimited.
He expects it to prove of great value
to hospitals, particularly for reducing
the temperature Of wards in which
fever patients are confined, and in ad-
dltion to it's use for cooling residences
and hotels, he ssys he selves The prob
lem Of individual cold storage.
Prof. Moore's invention, IN addition
to reducing temperature, washes,
cleanses and renders the air dry and
healthful. Hot air, filed with dust, lie
taken into the machine at temporal
ture of nearly 100 degrees aud expelled
almost instantly at temperature of
80 degrees and with its relative hu-
midity lessened by more than half.
The machine operates, as ita name
implies, on the principle of gravity
That Is, it makes use of the difference
in weight between air at high and at
low temperature. 1t is, moreover
automatic. 1t requires no motive
power and is self-adjustlng. Whel
the weather is very hot the machine
works faster than when it is only mod
erately warm, and when the weathe
is temperate the machine ceaees it's on
erations altogether. 1t is necessary t
change the machine only once da,
preferably In the morning, and then
will automatically keep the dwellin
IN which it is placed at a cool, eve
temperature.
! The gravity cooler, will, like stove.
be manufactured in all sizes from
small affair corresponding to stov
designed to heat one room to an in
mense cylinder, corresponding to DIR
heat furnace and capable Of offectuall
and quickly cooling every part of
large dwelling. Piof. Moore only re
Gently secured his patents and yestel
day was the first day the machine ha
been IN operation at the Weather Blu
| reau.
Secretary of Agriculture Wilson ha,
heard of Prof. Moore's machine an
walked to the Weather Bureau from
church yesterday morning. Mr.. Will
son was warm after his walk and toll
Prof. Moore he wanted to be "coole,
off," He was taken to the room
where the machine was in operation
and few minutes later buttoned u,
his coat and remarked that he did nc
| care to be frozen to death in summer
| The machine in operation at tn
Weather Bureau is much too large fo
the room in which it is placed an,
makes the room feel like the cold stor
age department. of a packing house.
Is of the size intended for q hospita
ward and was built for experiments
purposes.
Prof. Moore says that as soon as the
foreign patents are granted he will
make public the formula of the compo,
sition with which the machine Is
charged. He said, however, that the
composition contained no ammonia,
nor any of the usual ingredients of Or
dinary freezing mixtures. 'rhe re.
porter looked into sliding door of the
cylinder and saw lot of little wheels
pipes and slowly turning machinery
which, Prof. Moore explained, all de
pended upon the principle of gravit J
for motion. The top of tho brass cyl.
inder WAS perfectly dry, while the bot.
tom was coated with frost and ice, the
temperature of the air being graduated
through the various compartments Of
the cylin,ler, from about 90 degrees
when it entered, through a pipe at the
top, until it was discharged at 80 de
grees. An thermometer placed at tn
discharge pipe showed that the ma
chine was giving off 200 cubic feet OF
air minute, or 10000 feet an hour
The room in which the machine wa,
In operation contained 4 900 cubic fee
of air, and although the doors were be
ing opened and closed every few min
utes the temperature renamed belo,
90 degrees and the room was muc
too cold for comfort.
