of the Commissioners of Patents on the 6th October 1883.

"IMPROVEMENTS IN THE METHOD Of
PRODUCING WARMTH BY ABSORBING WATER VAPOR, THE WARMTH PRODUCED TO
BE APPLIED FOR PRODUCING STEAM OR OTHER PURPOSES." [a communication
from Moritz Honigmann, a person resident at Aachen in the Empire of Germany]
This Invention relates to the production of heat by the absorption of aqueous
vapor and the application of the heat so produced to generate steam, and for other
purposes. The Invention is based on the property of chemical compounds whose
solutions have a higher boiling point than that of water (for instance the chloride of
calcium and others) to absorb aqueous vapors and thereby to produce heat. The
beat so produced is applied to generate steam for working locomotive and other
steam engines without the use of fire, and the exhaust steam from the engine is
absorbed by means of the chemical compounds above referred to, thus producing
the heat for the generation of the steam.
I will describe an apparatus which may be used for the purpose of carrying this
method of working steam engines into effect, but I do not limit myself to any
particular construction of apparatus. I may use for instance one closed vessel

with the steam chest of the engine cylinder. The outer vessel is partly filled with
hot water and the inner vessel is partially filled with the absorbent of the exhaust
steam which is discharged therein from the cylinder, its absorption being
accompanied by the production of heat which is communicated to the surrounding
water in the outer vessel whereby steam is generated for use in the engine.
It is necessary from time to time to replenish the outer vessel with hot water
and to empty the inner vessel and recharge it with the absorbent compound.
SPECIFICATION in pursuance of the conditions of the Letters Patent filed by
the said Frank Wirth in the Patent-Office on the 5th April 1884.
FRANK WIRTH of the firm of Wirth and Company, Patent Solicitors, at
Frankfort on the Main in the Empire of Germany. "IMPROVEMENTS IN THE

METHOD OF PRODUCING WARMTH BY ABSORBING WATER VAPOUR, THE WARMTH

(A communication from Moritz Honigmann a person resident at Aachen in the
Empire of Germany.)
This Invention relates to the production of heat by the absorption of aqueous
vapor and the application of the heat so produced to generate steam, and for other
purposes.
The Invention is based on the property of chemical compounds whose solutions
have a higher boiling point than that of water (for instance the chloride of calcium
and others) to absorb aqueous vapors and thereby to produce heat. The heat so
produced is applied to generate steam for working locomotive and other steam
engines without the use of fire, and the exhaust steam from the engine is absorbed
by means of the chemical compounds above referred to, thus producing the heat for
the generation of the steam.
I will describe an apparatus which may be used for the purpose of carrying this
method of working steam engines into effect, but I do not limit myself to any
particular construction of apparatus.
I may use, for instance, one closed vessel within another, as represented in the
accompanying drawing the said vessels communicating respectively with the
exhaust and with the steam chest of the engine cylinder.
The outer vessel is partly filled with hot water and the inner vessel is partially
filled with the absorbent of the exhaust steam, which is discharged therein from
the cylinder, its absorption being accompanied by the production of heat which is
communicated to the surrounding water in the outer vessel whereby steam is
generated for use in the engine.
It is necessary from time to time to replenish the outer vessel with hot water
and to empty the inner vessel and re-charge it with the absorbent compound.

page_text: Having described the nature of the said Invention and the manner of performing
the same I declare that what I claim as the Invention to be protected by the
hereinbefore in part recited Letters Patent is:
The herein described method of producing steam under pressure by means of
chemical compounds whose solutions have a higher boiling point than that of
water.
In witness whereof I the said Frank Wirth have hereunto set my hand and
seal this third day of April A,D, 1884,
