COMPLETE SPECIFICATION.
Apparatus for the Production of Carbonic Acid Gas Baths.
I, LUDWIG KALLINA, of Teschen, in the Province of Oesterreich-Schlesien, in the
Empire, of Austria, Brewery Manager, do hereby declare the nature of this inven-
tion and in what manner the same is to be performed, to be particularly described
and ascertained in and by the following statement:-
-
The object of this invention is an arrangement by means of which carbonic
acid gas baths can be provided in a convenient and suitable manner for the whole
or for any part of the human body.
a
The apparatus consists essentially of a gas-tight bath chamber which can be
folded or closed up and into which gaseous carbonic acid, obtained from
generating apparatus or from a vessel containing compressed carbonic acid, can
bo introduced in a quantity which can be regulated through a suitable tube; and
when necessary of a heating device through which the carbonic acid passes on
its way to the bath-chamber and which serves to heat to the desired bath tempera-
ture any carbonic acid gas which may have become cooled through evaporation
and expansion.
The accompanying drawing illustrates a form of bath apparatus constructed
according to the invention.
a is a gas-tight chamber or container which has the shape of a bath-chair and
consists of wood covered on the inside or the outside with sheet-metal or merely
of sheet-metal or other suitable gas-tight material, the said chamber being pro-
vided at its upper open end with a gas-tight bag or cover b which is adapted
to make a gas-tight joint around the throat or the upper part of the body of
the bather For patients whom it is difficult to move the bath is made in three
parts which can be connected together in a gas-tight manner. The patient takes
his seat in the lowermost part or bottom of the bath and the two upper parts
thereof are then placed in position.
The carbonic acid gas is introduced into the bath a through a perforated tube
or spray d which is arranged in the lower part of the bath chamber and is con-
nected with the/tube c The tube c is connected with a carbonic acid gas generator
of a known kind; in the drawing I have shewn a cylinder e containing liquid car-
bonic acid gas, the said cylinder being provided with a cock f for regulating the
supply of gas. In the tube c there is fitted a warming or heating device g which
consists of a vessel having two partitions h and tubes arranged between them.
The tubes are filled with a liquid which is kept warm from any suitable source
of heat 3. The heating of the carbonic acid can be advantageously effected
by means of a flame or by allowing the gas to flow through hot water, any water
vapour which is carried away with the gas being deposited in condensing vessels.
The carbonic acid gas to be warmed flows between the tubes i, the said carbonic
acid, before it again enters the tube c, passing around a thermometer k which
indicates its temperature. By adjusting the cock f on the carbonic acid cylinder e,
the quantity of carbonic acid gas escaping per unit of time and therefore the
temperature of the gas bath can be regulated.

page_text: The bath chamber a can be either wholly or partially filled with carbonic acid
gas. In the latter case an air bath containing carbonic acid gas is obtained as
the air present in the bath chamber mixes with the carbonic acid gas.
The bath chamber a can have the form of a bag or a diver's dress and can be
made wholly of gas-tight material.
Having now particularly described and ascertained the nature of my said
invention and in what manner the same is to be performed, I declare that what
I claim is:-
Apparatus for the production of carbonic acid, gas baths consisting essentially
of a gas-tight bath chamber which can be folded or closed up and into which
gaseous carbonic acid, obtained from a gas generating apparatus or from a carbonic
acid cvlinder, can be introduced in a quantity which can be regulated; and, if
required, of a heating device through which the carbonic acid gas flows on its way
to the bath chamber and which serves to heat to the required bath temperature
any carbonic acid gas which may have become cooled by evaporation and expan-
sion, substantially as herein before described.
