Improvements in Apparatus for the Production of Ozone or
Ozonized Air.
I, ALBERT VERLEY of 69 Avenue de la Grande Armée, Paris, in the Republic
of France, Chemist, do hereby declare, the nature of my invention to be as
follows:
My invention has for its object to provide apparatus which can be conveniently
made of any desired size so as to be capable of readily producing ozone or ozonized
air in large quantities.
According to my invention I employ a sheet of polished copper, or other suitable
metal. and a sheet of silvered glass, or equivalent material, these sheets being
supported so that their respectively polished and unsilvered surfaces face each other,
and are at but a small distance apart. The said copper or like sheet and the silver
coating of the glass or the like are respectively connected to the two poles of a
transformer, or generator of a continuous electric current of say for instance from
5,000 to 12,000 volts. The air to be ozonised or from which ozone is to be
produced enters at the side, or sides, of the space between the said polished and
unsilvered surfaces and is subjected to the action of the electric effluvia passing
between the two sheets and so is ozonized and the ozone, or ozonized air, is drawn
or passes off by a pipe opening from the centre of the space between the two sheets.
Undue heating may be prevented by any suitable cooling medium; such for instance
as by a current of water, or by the expansion of compressed air. The apparatus
may be arranged in any suitable way; for example, a slate table may be mounted
on feet the slate being recessed so as to allow a current of water to circulate over
it. The lower part of the slate is covered by a polished copper plate connected
with one pole of a transformer or generator of electricity. Beneath the said copper
plate is supported a sheet of glass which may be forced by springs, or screws,
towards the copper plate, small caps or distance pieces maintaining the requisite
space between the metal plate and the glass plate. The glass plate is silvered ou
the side presented away from the polished surface of the copper plate, and the
other pole of the transformer, or electric generator is electrically connected with
the said silvering by a spring tongue. The space between the two plates may be
divided by glass rods, or the like, so that the said space is made to constitute a
spiral, or zig-zag, passage through which the air under operation passes to the
centre, in a spiral, or zig zag, direction, and from this centre the ozone, or ozouised
air, produced escapes, or is drawn off, through an orifice and outlet pipe. Or the
space may be divided by radially arranged rods or otherwise. The polished copper
sheet may, according to another example of an arrangement according to my
invention, be carried by the upper side of the table and the silvered glass be placed
on the copper sheet with the unsilvered side next it, distance pieces maintaining
the requisite space between the polished and unsilvered surfaces. Compressed air
may be passed through perforations in a pipe so as to effect the necessary cooling.
In an apparatus arranged or constructed according to my invention the sheet of
glass, or the like, can be made of considerable thickness, which is important, as it
is not possible to make very thin sheets with that truth of surface which is necessary.

Improvements in Apparatus for the Production of Ozone or.
Ozonized Air.
I, ALBERT VERLEY, of 69 Avenue de la Grande Armée, Paris, in the Republic
of France, 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:-
My invention has for its object to provide apparatus which can be conveniently
made of any desired size so as to be capable of readily producing ozone or ozonized
air in large quantities.
According to my invention I employ a sheet of polished copper, or other
suitable metal, and a sheet of silvered glass, or equivalent material, these sheets
being supported so that their respectively polished and un-ilvered surfaces face
each other, and are at but a small distance apart. The said copper or like sheet
and the silver coating of the glass or the like are respectively connected to
the two poles of a transformer, or generator of a continuous electric current, of
say for instance from 5000 to 12000 volts. The air to be ozonized or from
which ozone is to be produced enters at the side, or sides, of the space between
the said polished and unsilvered surfaces and is subjected to the action of the
electric effluvia passing between the two sheets and so is ozonized and the ozone,
or ozonized air, is drawn, or passes, off by pipe opening from the centre of the
space between the two sheets.
a
Undue heating may be prevented by any suitable cooling medium such, for
instance, as by a current of water, or by the expansion of compressed air. The
apparatus may be arranged in any suitable way and I describe examples with
reference to the accompanying drawings in which I have illustrated in transverse
section in Figure 1 and in plan in Figure 2 an apparatus constructed in
accordance with my invention and in Figures 3 and 4 I have shewn a transverse
section and a plan with the upper sheet removed of another construction of the
said apparatus ac ording to my invention. Figures 1 and 3 are enlarged
sections of portions of the tables and sheets of the respective arrangements.
The
a is the sheet of polished copper or other suitable metal and b is the sheet of
glass or equivalent material silvered on the side furthest from the sheet a.
sheet a is secured to the underside of the table e and fitting in the underside of the
framing or between the legs thereof so that it can be moved vertically in the said
framing as a guide is another framing d with legs e whose length is adjustable by
means of screws so that by this means the small space between the two sheets
can be adjusted and fixed accurately, air having access to the said space at the side
or sides thereof. 9h are the connections for the conductors connecting respectively
the silvering and the metal plate to the poles of the generator of electricity. The
contact with the silvering may be made by means of a metal spring tongue bearing
thereon. is a lead pipe by which the ozone or ozonized air passes to the holder
or place of utilization. The top of the table e may be of slate and is recessed at c
so as to allow a current of cooling liquid such as, water to circulate over it, the
said water escaping by the outlet c³. Sinall cups, or distance pieces placed in the

page_text: space between the sheets will maintain the requisite small distance between
the metal plate and the glass plate and springs may be used in place of the
screws. The space between the two plates may be divided by glass rods, or the
like, so that the said space is made to constitate a spiral, or zig-zag, passage
through which the air under operation passes to the centre, in a spiral, or zig-zag,
direction, and from this centre the ozone, or ozonized air produced, escapes, or is
drawn off, through an orifice and outlet pipe. This formation of a circuitous
passage is shewn in the plan Figure 4 of the second example where the rods which
form it are marked e. Or the space may be divided by radially arrangel rods or
otherwise. The polished copper sheet a may, according to the example shewn in
Figures 3 and 4 be carried by the upper side of the table c and the silvered glass b
be supported over the copper sheet with the unsilvered side next it, distance pieces
maintaining the requisite space between the polished and unsilvered surfaces.
Compressed gas such as air may be passed through perforations in a pipe j so as
to effect the necessary cooling. In this case the outlet pipe i passes from below.
In an apparatus arranged or constructed according to my invention the sheet of
glass or the like, can be made of considerable thickness, which is important, as it
is not possible to make very thin sheets with that truth of surface which is
necessary to give the requisite equality of distance between the polished metal
surface and the silvered surface throughout their whole extent.
By the term silvering I of course mean any metallic coating of sufficient
conductibility. The apparatus may be made of any convenient shape and the
details may be considerably varied withont departing from the nature of my
invention.
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. In apparatus for the production of ozone or ozonized air a sheet of polished
copper or other suitable metal and a sheet of glass or equivalent material silverod
on the side furthest from the metal sheet the sheet of metal and the silvering being
respectively connected to the poles of a source of electricity and the two sheets.
being supported at a small distance apart so as to leave a space between them and
an inlet for air and an outlet for ozone or ozonized air so arranged that air passes
from the inlet to the outlet through the said space and is ozonized in its passage,
substantially as hereinbefore described..
2. Iu apparatus for the pruduction of ozone or ozonized air a sheet of polished
copper or other suitable metal and a sheet of glass or equivalent material silvered
on the side furthest from the metal sheet, the sheet of metal and the silvering being

being supported at a small distance apart so as to leave a small space between them
with an inlet or inlets for air around the sides or edges of the said space and an
outlet or outlets for ozone or ozonized air communicating with the mid-portion of
the said space substantially as herein before described.
3. In apparatus for the production of zone or ozonized air a sheet of polished
copper or other suitable metal and a sheet of glass or equivalent material silvered
on the side furthest from the metal sheet, the sheet of metal and the silvering being
respectively connected with the poles of a source of electricity and the two sheets
being supported at a small distance apart so as to leave a small space between then
and partitions or distance strips between the sheets so arranged as to form a
circuitous passage or separate passages for air from the side or sides of the
said space to an outlet communicating therewith substantially as hereinbefore
described.
4. In combination with apparatus arranged as claimed by the preceding claiming
clauses means for adjusting the distance apart of the sheets of metal and glass or
equivalent material substantially as herein before described.
