Improvements in Apparatus for the Rapid and Economical
Production of Ozone by Electricity.
I JOSHUA HENRY LAMPREY of Hampton House Dulwich Rise S.E. in the
County of Surrey Literary Editor do hereby declare the nature of this invention
to be as follows:-
The object of my invention is to construct a simple and efficient apparatus for
the production of ozone by electricity.
My invention in its simplest form consists of one or two strips of glass or other
suitable non conducting material on one side of which strip or strips of glass is
placed one or more wires which are connected with one terminal of an alternating
current generator. This wire or wires being covered by a strip of tin foil or the
like which in turn is covered on the outer face with some insulating material and
made to adhere to the glass strip so as to keep the wire close to it.
On the other face of the glass strip or strips is placed a wire connected with the
other terminal of the electric generator on which is strung glass and metal beads
or discs alternately.
This wire is provided with beads or discs for nearly the entire length of the glass
strip leaving at the ends a space sufficient for the proper insulation of the two main
wires. When an alternating current is led into these wires the ozone is freely
given off from the metal beads strung on the wire.
A modification of the apparatus described above consists in arranging a central
wire or metal rod either coated with enamel or other suitable non conducting
material or encased in a tube of glass or the like.
This wire or rod is connected with one terminal of the generator and the other
wire connected with the opposite terminal carrying the alternate beads or discs of
metal and glass or the like as previously described is either wound spirally around
it or placed parallel with its axis in one or more rows when the ozone is given
off from the metal beads or discs on the application of the current as above
described.
The generation of ozone is greatly promoted by causing currents of air to
impinge upon the beads and the ozonised air is collected by any suitable means
and subsequently used for sanitary, sewage, bleaching, and all other purposes for
which ozone is known or may prove to be an efficient agent.

1 JOSHUA HENRY LAMPREY of Hampton House Dulwich Rise S.E. in the
County of Surrey Literary Editor 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 consists of the improvements hereinafter described in the
construction of apparatus for rapid and economical production of ozone by
electricity the object of my invention being to produce cheaper and more efficient
and more readily constructed apparatus for the said purpose than hins heretofore
been produced.
The simplest form of apparatus for the said purpose heretofore made consists of
two conductors separated by glass or other dielectric material and respectively
connected at one end only to the terminals of an alternating electric current
generator the other ends of the conductors being free or unconnected either with
the generator or with each other. One of the said conductors has usually consisted
of a plain plate of metal while the other has consisted in some cases of a metal
plate or strip bearing points on one of its faces and in other cases of comb
shaped metal plates or serrated wires or serrated strips of metal the office of the
points and comb teeth and serrations being to cause electric discharge to take place
at many parts of the conductor when the apparatus is properly connected to an
alternating current generator. Forms of apparatus of this nature for producing
ozone are described in the Specifications of Andreoli's Patents No. 9631 and
21794 A.D. 1892. The construction of the said apparatus with conductors of the
said forms (e. pointed comb shaped and serrated) is troublesome especially when
the surface which the points or teeth are required to be in contact with is of curved
form as there is much difficulty in pincing and keeping all the points or teeth in
contact with the glass or other dielectric material and out of contact with each other
which is necessary in order that the maximum effect may be produced by the
working of the said apparatus.
In order to obviate these objections I substitute conductors formed of wires on
which are strung metal beads or discs alternating with beads of glass or other
dielectric material for the said point bearing and comb shaped plates and serrated
wires and strips.
The accompanying drawings illustrate two arrangements of apparatus for the
production of zone the said apparatus being furnished with conductors formed
according to my invention. One of the said arrangements of apparatus is
illustrated in Figures 1, 2, 3 and 4 of the accompanying drawings Figure 1 being
a face view of the said apparatus Figure 2 an edge view and Figures 3 and 4
transverse sections thereof.
Referring to the said figures a a" are two strips of glass. b is one of the
conductors which is placed between the glass strips a a" and consists of a Hint plaiu
strip of metal one end of which projects beyond the glass strips and has a binding
screw c secured to it for connection to an electric current generator. The other
conductor (which is formed according to my invention) consists of a wire d on
which metal bends e and glass beads are secured alternately. by passing the said
wire through the holes in the said bende. The said wire is extended along the
outer faces of the two glass strips a, a" and has a binding screw y affixed to it for
connection to the current generator. The wired may be secured to the glass strips
at or near their ends by twisting it over the said strips as illustrated at h, and by
means of sealing wax or other suitable adhesive matter applied over the twisted
parts. Or the said wire may be secured at or near the ends of the glass strips in

page_text: any other simple and convenient manner. At intermediate points the said wire
may be held in place by binding thread around the said strips and over the said
wire as indicated by the lines marked i the metal beads being thereby held in
contact with the surface of the glass strips a a. The space between the two strips
of glass may be enclosed by pasting or otherwise securing paper to the said strips
and over their edges as illustrated at in Figure 3.
Figures 5 and 6 of the accompanying drawings illustrate in edge view and
transverse section respectively a portion of an apparatus of the form illustrated in
the figures already described but furnished with outer conductors consisting of a
wire or wires kk on which metal discs and glass beads m m are strung
alternately.

The other of the said arrangements is illustrated in side view and transverse
section respectively in Figures 7 and 8 of the accompanying drawings. Referring
to the said figures n is a glass tube within which is metal rod o constituting one of
the conductors. The other conductor which consists of a wire p having strung on
it metal beads g alternating with glass beads is coiled spirally around the said
tube n and secured thereto at its ends. stare binding screws which admit of the
said conductors being respectively connected to an electric generator as require 1.
In this arrangement it is desirable that the rod o be of such diameter as to be in
contact at all parts of its circumference with the interior surface of the glass
tube n surrounding it. If the diameter of the rod selected for use be less than the
internal diameter of the tube the intervening space should be packed with metal
filings or with metal in other convenient form.
Figure 9 is a transverse section of apparatus of the form illustrated in Figures 7
and 8 but furnished with an outer conductor consisting of a wire carrying metal
dises instead of metal beads. Referring to the said Figure 9 uu are the metal
discs and are glass beads which keep the said discs from contact with each
other.
The metal beads which I prefer to use in carrying out my invention are of the
kind known as "cut beads" but beads of other form are suitable. The perforated
metal discs known as <
spangles" are suitable and convenient for use according to
my invention. I do not confine myself to the use of glass beads for the purposo
of keeping the metal beads or discs apart as beads of other dielectric material
are suitable for the said purpose.
Although I have described and illustrated the application of my invention to
only two forms of apparatus for the production of ozone I wish it to be understood
that my said invention is applicable to other forms of such apparatus.
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 I
claim :-
:-
First. The arrangement and use in apparatus for the production of ozone by
electricity of conductors consisting of wires on which are strung metal beads or
discs alternating with beads of glass or other dielectric material substantially as
berein before described.
Secondly. The use of metal beads substantially as herein before described in the
construction of apparatus for the production of ozone by electricity.
