Improvements in or relating to Vapour Engines.
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:-
This invention consists, First; in an ordinary engine, of any approved con-
struction; Second; surface condenser, preferably consisting of several
perpendicular jars or cylinders, filled with coils of pipe, so as to hold a very small
amount of liquid around said coils. Third; a feed pump of special construction
connected with the coils in the condenser. Fourth; a gas pump capable of drawing
the gas from one part of the apparatus, and condensing it in another. Fifth; an
upright jar or cylinder filled with coils of pipe, said cylinder being connected with
the feed pump in such a manner that the pump draws the condensed gases from the
coils in the condenser and circulates the liquid on the outside of the coils in said
cylinder. Sixth; a nest of tubes, such as would constitute a boiler for ordinary
steam generating purposes, into which the liquid from the cylinder is discharged.
Seventh; minute valves, of peculiar construction, to give intermittent discharges
of gas through small orifices.
A compound of two gases, one of which boils at a lower temperature than the
other, is employed in my device, and these gases are injected, and allowed to
expand through one of the above mentioned small valves, into the condenser, until
said condenser is thoroughly cooled, so that the liquid gases partially fill the space
surrounding the coils. When this cooling is accomplished, the cylinder into which
the feed pump discharges, is cooled in the same manner, excepting that the gases in
expanding and cooling are allowed to pass through the coils representing the boiler,
and the heat absorbed furnishes sufficient pressure to drive the engine. The
exhaust discharges into the coils within the condenser which have been cooled
sufficiently to condense the gases into a liquid. As the engine starts, the pump,
actuated in any suitable manner, draws the gases from the liquid upon the outside
of the tubes or coils within the condenser, thereby producing intense cold. This
expanded gas is compressed in the coils within the cylinder, there giving up its
latent heat, to the cold liquid that is being pumped through said cylinder, on its
way to the tubes which represent the boiler, the said liquid being so cold that the
compressed gases in the coils are condensed at a low temperature. The liquid thus
formed, is forced by the pressure in the coils through a pipe to the top of the
condenser, and the expansion is so great, that the gas, boiling at a low temperature,
freezes solid the gas boiling at a higher temperature, besides partially freezing
itself, thereby producing intense cold. The exhaust gas from the engine melts the
solid gas, thus keeping up the supply of liquid, which is vaporized by the pump,
compressed into the cylinder, and thus circulation is maintained. It will thus be
seen that this is a closed circuit, as in an ordinary ice machine, in which the liquid
is vaporized in one place, compressed into another, where it gives up its heat, and
is then conveyed back to the first place, to keep up the circulation.
The operation of driving the engine is the same as in an ordinary steam engine ;
the liquid gas is forced into a jar or cylinder which represents the feed water
heater, until sufficient liquid has been supplied to run the engine, said liquid boiling
or vaporizing in the tubes, constituting the boiler, and then being condensed, after
use, in the condenser, and pumped again into the tubes representing the feed water
heater.

Improvements in or relating to Vapour Engines.
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 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 obtaining gaseous pressure, and to
an apparatus for utilizing the same, and has for its object the provision of a simple
apparatus whereby a compound of gases may be thus employed.
To attain the desired end, my invention consists essentially in mechanically
combining two gases, which boil at different temperatures, and passing the same
through condensers, and a vaporizer, and through an engine or motor, all of which
will be hereinafter first fully described, and then pointed out in the claims.
In the accompanying drawing is illustrated one form of apparatus designed for
carrying my invention into effect.
Similar numerals of reference, wherever they occur, indicate corresponding
parts.
This device consists, First: of an ordinary engine; Second, a surface condenser
of approved design preferably consisting of one or several perpendicular jars or
cylinders, filled with coils of pipe, so as to hold only a small amount of liquid
around them; Third, a feed pump connected with the condenser coils: Fourth a
pump capable of drawing the gases from one part of the apparatus, and compressing
it in another Fifth, in a jar or cylinder, filled with coils of pipe, said jar being
connected with the feed pump so that the pump draws the condensed gases from
the coils in the condenser, and circulates the liquid on the outside of the coils in
said jar Sixth, a nest of tubes, which would represent the boiler for ordinary
steam purposes, into which the liquid from the jar is discharged.
1 is an engine or motor, of any approved construction. 2 is a pipe, leading from
the exhaust of the engine, to a coil 3, in a cylinder 4. From this coil a pipe 5,
leads to a pump 6, and from the pump 6, a pipe 7, leads to a jar 8. At the top of
this jar 8, is a pipe 9, leading to a coil 10, representing an ordinary tube boiler.
From the coil 10, a pipe 11, leads to the supply of the engine 1.
This circuit is
indicated by a series of sharp pointed arrows.
12 is a supply pipe, arranged for charging the cylinder 4. 13 is a pipe connected
to said cylinder, and 14 is a regulating valve, mounted upon said pipe, and provided
with a stem 15. From the shell of valve 14, a pipe 16, leads to a coil 17, in the
jar 8, and a pipe 18 conducts from this coil to a pump 19. A pipe 20, leads from
the pump 19, back to the top of the cylinder 4, this circuit being illustrated by
the blunt headed arrows. 21 is a supply valve, provided with a manipulating
stem 22.
In operating this device, a compound of any two gases, one of which boils at a
lower temperature than the other, is employed. These gases are injected into
cylinder 4 through the pipe 12, and are allowed to expand in said condenser, until
it is thoroughly cooled, so that the liquid gases partially fill the space surrounding.
the coils 3. When this cooling has been accomplished, the jar 8 is cooled in the
same manner, excepting that the gas in expanding and cooling, is allowed to pass
through the coils 10, and the heat absorbed is utilized for driving the engine 1.
The exhaust from the engine discharges into the coils 3, within cylinder 4, which has
been cooled sufficiently to again convert the gas iuto a liquid. As the engine
starts, the pump 19, actuated in any suitable manner, draws the gas from the
liquid upon the outside of the tubes 3, thereby producing intense cold. This
expanded gas is condensed within the coil 17 in the jar 8, and there gives up its
latent heat to the cold liquid that is being pumped through said jar by the pump 6,
on its way to the tubes 10, representing the boiler, the said liquid being so cold

page_text: that the compressed gas in the coils 17 is condensed at a low temperature. The
liquid thus formed in the coil 17, is forced through the pipe 20 to the top of the
condenser 4, and the expansion as it passes into said condenser is so great, that
the gas boiling at a low temperature, freezes solid the gas boiling at a higher
temperature, besides partially freezing itself, thus producing intense cold. The
exhaust gas from the engine, passing into the coils 3, melts the solid gas
surrounding said coils thus keeping up the supply of liquid, which is kept in
circulation by the pump 19. The apparatus now being charged, heat is
applied to coil 10 in any desired manner, creating a pressure, which actuates the
engine, and thus the circulation is maintained. It will thus be seen that the liquid
gas is vaporized in one place, compressed in another, where it gives up its heat, and
is then conveyed back to the starting point, to keep up the circulation.
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 using a mechanical combination of gases
which boil at different temperatures, circulating the same through condensing and
vaporizing devices,, and driving a motor or engine therewith, substantially as
set forth.
2. In a motor of the character herein specified, the maintenence of the cold for
