for working locomo- tive and other steam engines without the use of fire
Year: 1883

page_text: I, FRANK WIRTH of the Firm of Wirth and Company, Patent Solicitors, at
Frankfort on the Main in the Empire of Germany seek leave to amend the
specification of Letters Patent N° 2018 of 1883, as shown in red ink in the
copy of the original specification hereunto annexed namely:
<
"
"
On page 2 line 15 of the Queens printers copy, by striking out the words
or other purposes" from the title and adding the words "for working locomo-
tive and other steam engines without the use of fire" and in line 18, by striking
out the words "and for after "steam and the two following words "other
purposes" in line 19. On page 3 line 4 by striking out the word "claim" and
inserting the words "disclaim broadly" before "the use' " and by adding the
following after the word "vapour" at end of claim "but what I claim is The
"herein described method of working locomotives and other steam engines with-
"out the use of fire by the absorption of the exhaust steam from the engine by
"caustic soda or potash lye which is in direct contact with the said steam
generator and thereby generating steam, the first steam being generated in
"the generator by hot water the heat of which has been derived from any
source of heat which is external and independent of the said locomotive or
engine."
"
"
My reasons for making this amendinent are as follows:
That since the said Letters Patent were granted it has been discovered that the
employment of caustic soda or potash for absorbing exhaust steam and thereby
producing heat was not at the time the said Letters Patent were applied for
broadly new and it is therefore desired to restrict the claim to the method of
working locomotives and other steam engines without the use of fire described
in the specification.

PRODUCING WARMTH BY ABSORBING WATER VAPOUR, 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 a method of producing heat by the absorption of
aqueous vapor and of applying the heat so produced to generate steam and for
other purposes and the invention has for its object a method of working locomotive
and other steam engines without the use of fire and is based on the property of
caustic soda and potash to absorb aqueous vapors and thereby to produce heat,
and consists in a mode of applying the heat so produced to generate steam and of
absorbing the exhaust steam from the engine by caustic soda or potash and so
producing heat for the generation of 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 the said vessels communicating respectively with the exhaust and
with the steam chest of the engine cylinder The inner vessel is partially filled
with dry or highly concentrated caustic potash or soda and the outer, vessel is
partly filled with hot water.. The exhaust steam from the cylinder is introduced
into the mass of the potash or soda by which it becomes absorbed this effect being
accompanied by the production of heat. This heat 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 refill it with dry or highly concentrated soda
or potash.
The diluted caustic soda or potash removed from the inner vessel may be
reconcentrated in evaporating paus or suitable boilers.

This Invention relates to a method of producing heat by the absorption of

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

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 inner vessel A is partially filled with dry or highly
