A Great Invention Exhibited by

gravity apparatus. for cooling dwell
ings, invented by Prof. Willis L.
Moore, chief Of the Weather Bureau,
patents for which were recently secur
ed, has been placed in operation for
public demonstration. The machine
looks like cylinder stove, and the in
ventor says will in time come to be
considered as essential to the COM
fort of a dwelling in summer as heat
ing apparatus in winter. Professor
Moore says that the cost of cooling a
given space with his machine is ap.
proximately the same as that of heat
ing the same space by means Of a stove
or furnace. Besides this, the different
uses to which the machine may be
put are unlimited. He expects 1t to
prove of great value to hospitals, par
ticularly for reducing the tempera-
ture of wards in which fever patients
are confined, and in addition to its use
for cooling residences and hotels he
says it solves the problem of individ-
ual 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
is taken into the machine at a tempera
ture of nearly 100 degrees, and expell-
ed almost instantly at temperature
of 80 degrees, and with its relative
humidity lessened by more than half.
The machine operates, as its name i'm
plies, on the principle of gravity. That
is, it makes use of the difference in
weight between air at high and at a
low temperature. 1t is, moreover, au-
tomato. 1t requires no motive power
and is self-adjusting. When the
weather is very hot the machine works
faster than when it is only moderately
warm, and when the weather is tenn
perate, the machine ceases its. opera
tion altogether 1t is necessary Ito
charge the machine only once a day
preferably in the morning, and it will
then automatically keep the dwelling
in which it is placed at cool, even
temperature. A;.t. ..f
The gravity cooler will, like stoves,
be manufactured in all sizes from
a small affair, corresponding to stove
designed to heat one room, to an i'm
mense cylinder, corresponding to a dry
heat furnace and capable Of effectually
and quickly cooling every part of a
large dwelling. Professor Moore only
recently secured his patents, and yes
terday was the first day the machine
has been in operation at the weather
bureau. ..a.
Secretary of Agriculture Wilson had
heard of Professor Moores machine
and walked to the Weather Bureau
Mr.. Wilson was warm after his walk,
and told the Professor he wanted to
be COOLED Off" He was taken to the
room where the machine was in op-
Grafton, and Il few minutes later but
toned up his coat and remarked that
he did not care to be frozen to death
in summer The machine in operation
at the Weather Bureau is much too
large for the room in which it is placed
and makes the room feel like the cold
storage department of packing house.
1t is of the size intended for hospi-
tai ward and was built for experiment
tai purposes.
Professor 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 ordin-
airy freezing mixtures. The reporter
looked into sliding door of the cylin.
der and saw a lot of little wheels,
pipes and slowly turning machinery.
which. Professor Moore explained, all
depended upon the principle of gravity
for motion. The top of the 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 cylinder, from about 90 degrees
when 1t entered, through a pipe at the
top, until it was discharged at 80 de-
grees. An anemometer placed at the
discharge pipe showed that the ma
chine was giving off 200 cubic feet
of air a minute, or 12,000 feet an hour.
The room in which the machine was in
onaro tion contained 0OO cubic foot of
