Improvements in Means for the Manufacture or Production.
of Ozone.
We, ARTHUR BRIN of 59 Brompton Crescent in the County of Middlesex, Engineer
and Chemist and LEON QUENTIN BRIN of 7 Rue Gavarni, Paris in the Republic of
France, Engineer and Chemist do hereby declare the nature of this Invention to
be as follows:-
The object of our Invention is to overcome the difficulties hitherto attending the
production of ozone and to enable it to be produced on a commercial scale of sufficient
strength for employment in the arts or for the purposes to which ozone is applicable.
For this purpose we cause a great number of electric sparks to pass through oxygen
or through atmospheric air by making a passage for the oxygen or atmospheric air
under treatment so that it is conducted between layers or masses of granulated or
divided or many-pointed conducting material contained in or supported by any
suitable containers or holders. The layer or mass of granules or series of points on
one side of the passage through which the oxygen or air passes is connected to one
pole of a generator of electricity and the layer or mass of granules or series of points
on the other side of the said space is connected to the other pole of the generator so
that when the current is passed there is an energetic sparking of a great number of
small sparks across the space through which the oxygen or air is passing owing to
the current crossing the said space from and to the granules or points on one side to
and from those on the other side whereby ozone is formed which can be drawn off
and utilized as required.

Improvements in Means for the Manufacture or Production
of Ozone.
We ARTHUR BRIN of 59 Brompton Crescent in the County of Middlesex Engineer
and Chemist and LEON QUENTIN BRIN of 7 Rue Gavarni Paris in the Republic
of France Engineer and Chemist 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:-
The appliances hitherto employed or proposed for the purpose of producing Ozone
and generally called Ozono-generators have been wanting in electrifying surface or
field, and it has not been hitherto found practicable to make on a commercial Scale
Ozone of a strength suited for the purposes to which Ozone is applicable.
In Wilds' Ozono-generator for example the Oxygen gas, or the air from which the
Ozone is proposed to be made has to pass through a tube placed between two other
tubes containing acidulated water or a solution of Sulphate of Copper or other
mineral salt. In this case the current meets with enormous resistance.
The object of our Invention is to overcome the difficulties hitherto attending the
production of Ozone and to enable it to be produced or manufactured on Commercial
Scale and of sufficient strength for employment in the arts or for the purposes to
which Ozone is applicable. For this purpose we pass the Electric Current across or
between such materials as offer isolated asperities or points or separate granules, so as
to produce a large number of sparks which pass through the Oxygen or the atmo-
spheric air under treatment. This we effect by making the passage for the Oxygen
or air under treatment between extensive conducting surfaces or matter presenting a
number of points or separate parts or between tubes or other containers or holders
filled with or supporting granular or divided conducting material the poles of an electric
Generator being so connected thereto respectively that the current in passing across
the space between them gives a large number of small sparks playing through a large
space. The tubes Containers or supports themselves should be of a material which
will not interfere with the sparking of the current. On the circuit of the Electric
generator being completed the sparks pass in great number and with great energy
between the points or granules or the like across the space containing the Oxygen or
air, and Ozone is formed which can be drawn off and utilized as required.
We do not limit ourselves to the use of any precise construction or arrangement of
apparatus but in order that our Invention may be thoroughly understood we will
describe with reference to the accompanying drawings the best means with which we
are acquainted for carrying it into practical effect. Figure 1 is an elevation partly
in longitudinal Section. Figure 2 is a transverse section and Figure 3 is a plan of
the apparatus.
We employ a series of sets each consisting of three tubes A, B, C of different
diameters placed concentrically one within the other. The centre tubes (and the

page_text: annular spaces between the outer tubes A and the intermediate tubes B contain solid
matter of high conductivity in the herein before mentioned condition such as granular
plumbago, iron filings, zinc filings, or copper filings, or dust shot.
The Oxygen gas or air passes through the spaces between the centre tubes C and
the intermediate tubes B and is most thoroughly and powerfully electrified by the
sparks passing through it from the material contained in the centre tubes to the
material contained in the annular spaces between the outside tubes A and the inter-
mediate tubes B or vice versa.
The matters contained in the spaces between the tubes A and B and that contained
in the tubes C are connected with the respective poles of any suitable electric
generator such as a dynamo machine producing an intermittent current. The con-
nections with the poles of the electric generator are shewn as being formed with
regard to one pole by the conducting rods inserted into the material in the tubes C
and electrically connected all to one bar e leading to the one pole of the generator,
the connection with the other pole of the generator being similarly formed by the
rods a² inserted into the material in the tubes A and led to binding screws which are
in electrical connection with the bar a leading to the other pole of the generator.
The annular space of each set of tubes through which the Oxygen or air passes is
in communication with that next to it by the passages b so that the Oxygen or air
passes from one to the other through the whole series and the Ozone formed escapes
by the outlet from the last of the spaces.
By the means described we are able to subdivide what under ordinary conditions
would be one electric spark of great length, and emitted at one point, into a very
great number of small sparks emitted through a considerable space, which sparks
passing through the stream of Oxygen gas or air act on it so as to convert it into
pure Ozone of great strength where Oxygen used, but where air is acted on the
produced Ozone will not be so strong but still will be useful in many important
applications in medicine for example in producing a curative or purifying atmosphere
in hospital wards.
Having now particularly described and ascertained the nature of our said
Invention and in what manner the same is to be performed we declare that what
we claim is :-
First: In producing or manufacturing ozone passing the Oxygen or air from
which the Ozone is to be formed between layers or masses of divided or granular or
many pointed conducting material connected respectively with the poles of an Electric
Generator so that numerous sparks are caused to pass through the Oxygen or air in
the manner specified.
Second: The apparatus for the manufacture of Ozone arranged substantially as
herein before described and illustrated in the accompanying Drawing.
