Improvements relating to Carbonic Acid Baths and Tablets for
use therein.
I, ERNST SANDOW, Doctor of Philosophy of Fruchtallee Hamburg in the
Empire of Germany 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 :-
This invention relates to carbonic acid baths, or baths in which carbonic acid
gases is contained in or given off in or from the water in which the bathing is
performed. Heretofore such baths have been produced artificially by causing
bicarbonate of soda to be decomposed in the water by means of muriatic acid.
The danger of using muriatic acid and the regulations affecting transport of acids
are disadvantages incident to this process. It has the further disadvantage that
the production of carbonic acid in the water quickly ceases the action being rapid
and soon completed.
The purpose of the present invention is to avoid the above disadvantages and
it has the special advantage over the above process and also over natural carbonic
acid baths in that the gas developed may be specially directed to any parts of the
body which are to be specially treated so that the development and local application
of the gas are under the control of the bather.
These improvements are attained by the use of a material made up in the form
of a soluble tablet, ball, rod or any other suitable shape or form so that it may
be placed in the water in which the bicarbonate of soda has been previously
dissolved, and thus dissolve and act on said bicarbonate of soda in a gradual and
sustained manner and in such locality that the gas developed may set as desired
by the bather.
In carrying out this invention a suitable tablet is maile by melting bisulphate
of soda, either alone or if an artificial steel bath is also to be had, with the desired
addition of ferrous sulphate. The fluid mass is poured into moulds of suitable size
and weight.
In preparing the bath the usual amount of bicarbonate of soda is first dissolved
in the water and after the bather has entered the bath one or more of these
tablets are placed on the floor of the bath so as to dissolve and act on the
bicarbonate in the water.
By this system the bather may move the tablets about so as to cause the gas
to act on any parts of the body desired.
Having now particularly described and ascertained the nature of my said inven-
tion I declare that what I claim is ;-
1. The method of producing improved carbonic acid baths by the introduction
of soluble tablets into the water in which the bather is immersed the materials
being adapted to produce carbonic acid by action on the bicarbonate of soda or
other suitable salt previously dissolved in the water.
2. Tablets composed of melted bisulphate of soda cast in suitable moulds for the
purpose set forth.
3. Tablets composed of bisulphate of soda and ferrous sulphate melted together
and cast in suitable moulds for the purpose set forth.
