PROVISIONAL SPECIFICATION.
New or Improved Apparatus for the Production of Ozone by Means
of Phosphorus.
I, CHRISTEN RAVNSBÆK POULSEN of Horsens in the Kingdom of Denmark,
Lieutenant of the Infantry Reserve and Custom House Officer do hereby declare
the nature of this invention to be as follows:
-
My invention refers to the production of ozone by means of phosphorus,
principally for being inhaled in cases of diseases of the chest and tuberculosis.
The apparatus consists of a reservoir or bottle made of glass or other suitable
material having a glass or porcelain perforated top or cap through which goes a
rod formed of the same material. The lower end of this rod is bent round and
formed with a cup holder or receptacle somewhat similar to a candlestick or
otherwise into or on to which a stick of phosphorus is placed.
The top or cap is provided with a cork having a hole, through which goes the
rod of the phosphorus holder and in such manner as to allow of the same being
moved up and down with slight friction and normally held at any desired altitude
in the reservoir. Inside the reservoir and at some distance below the outer cap or
top and on a shoulder or otherwise held is a perforated porcelain or glass plate also
provided with a hole for the passage of the porcelain rod. The perforations in
this plate and in the top allow of the exit of the pure ozone out into the room
or other place while the phosphoric acid gas is retained in the reservoir.

COMPLETE SPECIFICATION (AMENDED).
New or Improved Apparatus for the Production of Ozone by Means
of Phosphorus.
I, CHRISTEN RAVNSBÆK POULSEN of Horsens in the Kingdom of Denmark,
Lieutenant of the Infantry Reserve and Custom House Officer 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 :-
My invention refers to an improved construction of apparatus for the production
of ozone by means of phosphorus by which construction the phosphorus acid
developed in the apparatus is separated and transformed into phosphoric acid and
only the pure ozone finds its way out of the apparatus. This ozone is principally
intended for being inhaled in cases of tuberculosis and other diseases of the
chest.
The invention is illustrated by the accompanying vertical section through an
apparatus constructed according to the invention,

page_text: A is a reservoir or bottle made of glass or other suitable material having a
perforated glass or porcelain top or cap B through which is passed a rod C
formed of the same material. The lower end of this rod is bent round and
formed with a cup holder, or receptacle C₁ which may as shewn be somewhat
similar to a candlestick into or on to which a stick D of phosphorus is placed.
The neck of the top or cap B is provided with a cork E having a hole through
which is passed the rod C and in such manner as to allow of the same being
moved up and down with slight friction and to be normally held at any desired
altitude in the reservoir A. The upper end of the phosphorus-stick D is at the
level of the liquid F placed in the reservoir A. This liquid consists of distilled
water with an addition of about 10 per cent. chemically pure sulphuric acid; to
the mixture is also added some permanganate of potash but no more than that
the liquid in the reservoir is transparent when tested by placing some of the liquid in
a tumbler and holding it to the light and which would represent about one gramme of the
permanganate per 14 litres of the liquid. A larger quantity of the permanganate may
be used but the ozone then given off is liable to be. impure, wherefore I prefer to use the
weaker solution and to add occasionally small quantities of the permanganate. Inside
the reservoir and at some distance below the outer cap or top B and resting on a
shoulder or otherwise held is a finely perforated porcelain or glass plate G also
provided with a hole for the passage of the rod C through it. The perforations in
this plate and in the top B allow of the exit of the pure ozone out into the room or
other place while the phosphoric acid is retained in the reservoir. The phosphorus
acid developed by the oxydation of the phosphorus will in rising be stopped by
the plate G and be deflected down upon the liquid and be absorbed by it and
transformed into phosphoric acid while the ozone simultaneously developed by the
oxydation-process will pass up through the fine holes in the plate G and in the
cap B. The plate G thus effects a separation of phosphorus acid while the ozone
is passing off is perfectly pure.
Having now particularly described and ascertained the nature of my said inven-
tion and in what manner the same is to be performed I declare that what I
claim is :-
1. Apparatus for production of ozone by means of phosphorus consisting of a
liquid reservoir provided with perforated cap or lid, a finely perforated diaphragm
between the same and the level of the liquid, and a holder containing a piece of
phosphorus in the liquid, the latter consisting of distilled water wherein is dissolved
about ten per cent, of chemically pure sulphuric acid and some permanganate of
potash the apparatus operating so that the phosphorus acid developed is transformed
into phosphoric acid while pure ozone escapes through the perforated cap substan-
tially as set forth.
2. The apparatus shewn on the drawing containing the liquid F and the
phosphorus D and operating as set forth.
