PROVISIONAL SPECIFICATION.
An Improved Gas Condenser.
I, CHARLES EASTMAN TRIPLER, Chemist, of No. 40 W. 77th Street, New
York City, State of New York, United States of America, do hereby declare the
nature of this invention to be as follows:-
The object of this invention is to provide means and mechanism for liquefying any
kind of gas by the production of a very low temperature.
To attain the desired end, I provide two independent circuits or conduits, the
first for the cooling medium, and the second for the gas to be reduced to a liquid.
In operating my invention, liquid carbonic acid, or the equivalent, is expanded
through a small feed valve into a condenser, and the expanded gas is allowed to
escape from the first condenser, into a second, through a proper valve, and from the
second condenser the gas is allowed to escape through a cock.. The gas in the first
condenser is frozen solid, and when this condensor is sufficiently cooled, the escape
cock from the second condenser is closed and a pump connected to said second
condenser is started, drawing the gas therefrom, and compressing it within a coil of
pipe contained in the first condenser. The cold produced by the solid gas in this
condenser is sufficient to condense the compressed gas to several atmospheres.
From the coil the gas goes to a receiver or storage jar. A valve from this receiver
is now opened, and the liquid gas allowed to expand, as previously above described,
in starting the operation of the apparatus, the original feed valve being now closed.
The pump continues to draw the exhaust gas from the second condenser, compressing
it in the coil in the first condenser, where it is liquefied, and then allowed to again
expand. In a short time, when all the heat of the apparatus has been absorbed, as
there is no more heat to expand or melt the solid gas, all the gas will be in a solid
state.
In the second condenser is a coil of pipe, which is now cooled to such a temperature
that it will condense any gas boiling at a higher temperature than carbonic acid,
without the application of any pressure, by simply passing the gas therethrough, or
it will condense any gas boiling at a lower temperature, if sufficient pressure is
applied.

An Improved Gas Condenser.
1, CHARLES EASTMAN TRIPLER, Chemist, of No. 40 W. 77th Street, New
York City, State of New York, United States of America, do hereby declare the
nature of this invention, and in what manner the same is to be performed, to be
particularly described and ascertained in and by the following statement :-
My invention relates especially to a method of condensing gas, without or with
pressure, and to an apparatus for carrying my method into effect, and has for its
object the provision of meaus and mechanism whereby gases may be condensed for
confining or storing, or for immediate use.
To attain the desired end, my invention consists in a novel and useful apparatus
for condensing gases of various descriptions, and in a peculiar method of accom-
plishing such condensation, all of which will be hereinafter first fully described,
and then pointed out in the claims.

page_text: The accompanying drawing illustrates in elevation a simple apparatus for carrying
my invention into effect.
14 is
Like numerals of reference, wherever they occur, indicate corresponding parts.
1 is a small pipe, leading to a valve, 2, the stem, 3, whereof is provided with a
hand wheel 4. This valve is connected to an expansion cylinder or chamber, 6.
7 is a pipe leading from the top of the cylinder 6 to a valve shell 8, the stem 9, of
the valve therein being provided with a crank, 10. The valve shell 8 is mounted
upon a pipe 12, communicating with an expansion cylinder, or chamber 13.
a small blow-off cock. 15 is a pipe leading from the top of the cylinder or
chamber 13 to a pump, 16. 17 is a pipe leading from the pump 16 to a coil of
pipe, 18, within the cylinder or chamber 6; 19 is a pipe which leads from the
coil 18 to a receiver, 20. 21 is a pipe leading from the receiver 20 to a valve 22,
the stem, 23, whereof is provided with a crank 24. 26 is a pipe connecting the
shell of valve 22 with the cylinder or chamber 6. 32 is a small cock in the top of
the receiver. 27 is a pressure gauge of any approved construction mounted upon
a pipe 28 communicating with the chamber 6.
29 is an inlet pipe, leading to a coil 30 within the cylinder or chamber 13,
and 31 is an egress pipe leading from said coil.
When constructed in accordance with the foregoing description, the operation of
my device, and my method of condensing gas is carried into effect as follows:
Liquid is allowed to expand through the valve 2 into the expansion cylinder or
chamber 6. The expanded gas escapes through the pipe 7 and valve 8 into the
expansion cylinder 13, from whence, in starting the apparatus, it is allowed to
escape through the cock 14. The gas in the chamber 6 is frozen solid, and when
said chamber is sufficiently cooled, the cock 14 is closed, and the pump 16 is
started, drawing the gas from the cylinder 13, and compressing it in the coil 18 in
the cylinder or chamber 6. From the coil 18, the liquid gas goes to the receiver 20.
The valve 2 is now closed, and the valve 22 is opened, and the liquid gas allowed
to expand therethrough the same as it did previously through the valve 2.
pump continues to draw the gas from the cylinder 13, compressing it in the coil 18,
where it is liquefied, and allowed to expand again through the valve 22. In a
short time when all the heat is abstracted from the apparatus, as there is no more
heat to expand or melt the solid gas, all of the gas will be in a solid condition.
The
The coil 30 in the cylinder or chamber 13 is now cooled to such a temperature
that it will condense any gases passed therethrough, boiling at a higher temperature
than the circulating gas, and this without pressure, and it will condense any gas
boiling at a lower temperature than the circulating gas, if the requisite pressure is
applied. The gas to be condensed is introduced through the pipe 29, and is drawn
off in a liquid state through the pipe 31. It will thus be seen that very simple and
effective means are provided for condensing gas for various uses and purposes.
Having now particularly described and ascertained the nature of my said inven-
tion and in what manner the same is to be performed, I declare that what I
claim, is:
1. The herein described method of gas, that is to say, by the circulation of a
liquid gas, and expansion of the same in a closed circuit, whereby the cold produced
by its own expansion is utilized to recondense the same gas, substantially as set
forth and described.
2. An apparatus for condensing gas, in which is comprised a circuit for cooling
gas consisting of a chamber or cylinder, a circuit from said chamber through a
second expansion chamber or cylinder, then through a circulating device and coil
back to the expansion cylinder, and a second independent gas condensing circuit
located in the path of first described circuit, the whole combined and arranged to
operate, substantially as shown and described.
3. A gas condenser in which is comprised an expansion chamber or cylinder, a
second chamber or cylinder connected therewith; a conduit from said second
chamber to a circulating device; a conduit from said circulating device to a

page_text: condensing coil located within the expansion chamber; a receiver connected with
said coil and with the expansion chamber; and an independent condensing coil
located within the second chamber or cylinder, the whole combined and arranged to
operate, substantially as shown and described.
4. The herein described method of producing and maintaining cold, by
circulating a liquid gas, under pressure, through coils or tubes, then allowing it to
expand over said tubes, thus reducing the temperature of the liquid, as set
forth.
5. The condensation of a current of gas by the expansion of itself over the
conduit through which it passes, as set forth.
