TODOAWAY WITHICE
A New Invention to Cool Water on
Trains by Condensed Air.
THE PROCESS TO BE TESTED SOON,
Possibility of Its Use in Storage Houses and
Other Buildings.
THE PLAN OF A PITTSBURG RESIDENT

If present indications don't deceive, Pitts
burg with her fame for producing inventions
promises to give to .the world, through one
Of her citizens, an invention, which, if a
success, would benefit millions and defy
nature when she fails to give US ice enough
to counteract in a measure the effects Of the
heat in summer. The invention is the doing
away with ice entirely, or ice machines, and
not only that, but Transforming the hottest
air that blows into the coolest, and using it
to cool drinking water, refrigerators and
anything requiring the use of ice.
Henry j. Moreland, a brother Of City At
torney Moreland, is the inventor. and yes
terday showed a DISPATCH reporter his
plans. As far as perfected the invention is
only designed to cool the drinking water in
railroad trains. 1t consists OF an ordinary
water cooler, surrounded by 'jacket" or
second cooler, with space between the two,
and larger space at the bottom.
HOW IT FAIRLY FREEZES.
A pipe leads from the cooler, underneath
ends. Another pipe leads from the cooler to
the TOP OF the car.
When in operation faucet attachment
connects the funnel under the car (Which
faces in the direction the train is going)
with the cooler. With the motion of the
train the air is forced into the pipe and
compressed. When it reaches the vacuum
about the cooler it is condensed and, after
giving its influence to the water, passes off
by the pipe at the top.
As an illustration of the effect Of COM
pressed air being condensed to decrease the
temperature, the inventor cited fact dis
covered in experimenting with compressed
air in France as a motive power for engines,
description of which is given as follows:
"As the compression of the air produces
high degree of heat, so its expansion when
admitted to an engine causes an intense de-
gree OF cold. Whatever there is freezable
about the engine in the form of oil or water
is frozen stiff.
A NOTABLE OBSTACLE.
''The trouble from this source, however,
has been obviated by a simple device Of
heating the air before its admission to the
cylinder to such a temperature that when
it escapes it shall not be below 800 Fahren-
heit. This is easily done by the applica-
ton OF gas jet or flame from lamp
is fed to the cylinder. The whole key to
the invention is the simple fact that con-
densed air cools, the same as the ice in its
compressed state melts or is condensed, the
principle being merely changed from ice to
air, making the effect the same. Mr.. More
land has been studying matters pertaining
to ice and cooling processes or some time, and
hit upon his device before he had learned of
the fact being known in France"
Mr.. Moreland has obtained a caveat hold.
ing his principle of cooling water Tor one
year against other inventors, and Is now
negotiating with a railroad in the city to
put his invention to practical test.
The inventor is also working on a plan
embracing the same principle to cool the
water in houses for refrigerator purposes
One plan is to create q vacuum above the
water by
DRAWING OFF THE WARM AIR,
or evaporation, from the water, vacuum
pump being used. The other plan is to use
a pump to compress the air in the coolers in
buildings, all the coolers in each room in a
large building being connected with the
pump in the basement. The principle of
cooling the water would be the same as that
of the railroad cooler. This plan would be
limitless in its effect, and could be used on
a large scale for storage houses.
By having an air pump on railroad en-
gines, it would be possible to equip refrig-
orator cars with the invention, and do away
with ice, making it possible to turn the very
air that commonly spoils fruit en- route into
a preserver.
Mr.. Moreland thinks he has good thing
in his invention, and is anxiously awaiting
a trial to prove its success, although he says
it cannot fail from the very principles In
volved.
