A Machine or Apparatus for Simultaneous Production of Motive-
power and Cold.
İ, HERBERT JOHN HADDAN, of the firm of Herbert & Co., Patent Agents, of
18, Buckingham Street, Strand, W.C. London, in the County of Middlesex, Civil
Engineer, do hereby declare the nature of this invention, a communication to me from
abroad by Carl Kortüm, of Berlin, in the Empire of Germany, Engineer, to be as
follows:-
This invention consists in a machine or apparatus for simultaneous production of
motive-power and so called cold by absorption of caloric from the surrounding
space.
This machine consists in the following parts:
First. A cylinder with inlet and outlet valves (cocks or slides) piston, piston-rod,
crank, fly-wheel and regulator etc., in which the vapour of compressible gases or
volatile liquids by accomplishing mechanical labour and by expansion obtains such a
decrease of its temperature, as necessary for its complete or partial liquefaction, or
instead of this one cylinder several such cylinders or rotary engine for such
purpose.
Second. A collecting and separating vessel for instance a serpent-pipe for receiving
the liquid or the mixture of liquid and vapour discharged from the cylinder and for
eventually separating the vapour from the liquid and for emitting the vapour through
a loaded valve into a gasometer or into a compressor.
Third. A pump of known construction for sucking the liquid from the separating
vessel and for forcing it in a vaporizer or a liquid-chamber.
Fourth. A gasometer of known construction for receiving the vapour separated
from the liquid within the separator, as also that vapour which may have escaped
through the stuffing-boxes of the cylinder or of the pump.
Fifth. A chamber for receiving liquid from the pump or for emitting liquid into a
vaporizer.
Sixth. A vaporizer, for instance a pipe-system or tubular-boiler within which the
liquid transmitted froin the liquid chamber or discharged by the pump by taking up
heat from the surrounding medium is converted into vapour, which vapour passes to
the cylinder.
Seventh. An injector of known construction, or a system of such injectors, inter-
located between the vaporizer and the cylinder and destined to compress the vapour
of low pressure from the gasometer and to force it into the cylinder.
All the before mentioned parts communicate together by suitable pipes and are
provided with the necessary inlet, outlet, check and reducing valves (cocks or slides)
so that the machine operates as follows:
Through the opened outlet-valve of the vaporizer vapour of appropriate tension
passes, eventually passing the injector from the vaporizer into the cylinder as long as
the expansion-valve of the said cylinder, governed by a suitable mechanism, remains
opened. The vapour expanding and by moving the piston exerting mechanical force
loses by its expansion such a quantity of heat, that, in spite of the simultaneous
decrease of its tension, it becomes totally or partially liquefied in a measure
corresponding to its force and expansion.
The liquid so condensed, or the mixture of liquid and vapour, now, by the back-
stroke of the piston, discharged into the separator within which the liquid is separated
from the vapour.
This vapour passes through a suitably constructed valve, from the separator into
the gasometer from which it is sucked out and carried into the cylinder by the aid of
the injector and by the vanour passing from the vaporizer to the cylinder

page_text: At the same time the pump forces the liquid collected in the separator into the
vaporizer.
The speed of the piston of the cylinder may be regulated by the aid of a governor
or by a suitable brake on the fly-wheel or on a separate brake-pulley.

A Machine or Apparatus for Simultaneous Production of Motive-
power and Cold.
1 HERBERT JOHN HADDAN of the firm of Herbert & Co. Patent Agents of
18 Buckingham Street Strand W.C. London Civil Engineer do hereby declare the
nature of this invention a communication to me from abroad by Carl Kortüm of
Berlin in the Empire of Germany Engineer and in what manner the same is to
be performed to be particularly described and ascertained in and by the following
statement :-
This invention consists in a machine or apparatus for simultaneous production of
motive power and so called cold by the absorbtion of caloric from the surrounding
space.
This machine is represented in the annexed diagramatic drawing and consists in the
following parts first
-
A cylinder A with inlet and outlet valves (cocks or sliders) piston, piston rod,
crank fly wheel and regulator etc. in which the vapour of compressible gases or volatile
liquids by accomplishing mechanical labour and by expansion obtains such a decrease
of its temperature-as necessary for its complete or partial liquefaction or instead of
this one cylinder several cylinders or rotary engine for such purpose, second, a
collecting and separating vessel T for instance a serpent pipe for receiving the liquid
or the mixture of liquid and vapour discharged from the cylinder and for eventually
separating the vapour from the liquid and for emitting the vapour through a loaded
valve into a gasometer or into a compressor, third, a pump B of known construction
for sucking the liquid from the separating vessel and for forcing it in a vaporizer or a
liquid chamber, fourth a gasometer G of known construction for receiving the vapour
separated from the liquid within the separator T as also that vapour which may have
escaped through the stuffing boxes of the cylinder A or of the pump B, fifth, a
chamber M for receiving liquid from the pump B or for emitting liquid into a
vaporizer, sixth, a vaporizer for instance a pipe system or tubular boiler within
which the liquid, transmitted from the liquid chamber M or discharged by the pump B
by taking up heat from the surrounding medium is converted into vapour which
vapour passes to the cylinder A, seventh, an injector J of known construction or a
system of such injectors interlocated between the vaporizer V and the cylinder A and
destined to compress the vapour of low pressure from the gasometer G and to force
it into the cylinder A.
All the before mentioned parts communicate together by suitable pipes and are
provided with the necessary inlet, outlet, check and reducing valves (cocks or sliders)
so that the machine operates as follows.
Through the opened outlet valve of the vaporizer V vapour of appropriate tension
passes, eventually passing the injector J from the vaporizer V into the cylinder A as
long as the expansion valve of the said cylinder governed by a suitable mechanism
remains opened. The vapour expanding and hy moving the piston exerting mechanical
force looses by its expansion such a quantity of heat, that in spite of the simultaneous
decrease of its tension it becomes totally or partially liquified in a measure corre-
sponding to its force and expansion. The liquid so condensed or the mixture of liquid
and vapour is now, by the backstroke of the piston, discharged into the separator T
within which the liquid is separated from the vapour.
This vapour passes through a suitably constructed valve from the separator T into

page_text: the gasometer G from which it is sucked out and carried into the cylinder by the aid
of the injector and by the vapour passing from the vaporizer V to the cylinder A.
At the same time the pump B forces the liquid collected in the separator T into the
vaporizer V.
The speed of the piston of the cylinder A may be regulated by the aid of a governor
or a suitable brake on the fly wheel or on a separate brake pulley.
Having now particularly described and ascertained the nature of this inven-
tion and in what manner the same is to be performed 1 declare that what I
claim is
.
A machine consisting in one or more cylinders with inlet and outlet valves (cocks
or sliders) piston, piston rod connecting rod, Hy wheel etc. or in a rotary engine in
which vapour of liquifiable gases or volatile liquids coming from a vaporizer expands
and accomplishes mechanical labour and thereby is cooled so far as to be condensed
totally or partially to a liquid, which liquid, then forced into a vaporizer and
revaporized therein by receiving heat repeatedly passes through the same process
substantially as herein described.
