page_text: I, HILARION ANTOINE BERNARD HUGUET DE VARS, of 22 Chaussée d'Antin
Paris, France, Doctor of Medicine, do hereby declare the nature of this inven
tion and in what manner the same is to be performed, to be particularly described
and ascertained in and by the following statement :--
My invention relates to an apparatus for producing ozone by an entirely new
process. In order to make my invention more clearly understood, I shall now refer
to the accompanying drawings, in which
Fig. 1 is a vertical section of my ozone producing apparatus, and
Fig. 2 a top view of the apparatus at the line ay fig. 1.
The same letters of reference indicate corresponding parts in both figures.
My ozone producing apparatus consists as follows:
1. Of an ebonite stand E in which circular grooves are contrived to fit and receive
the lower circumference of a glass cylinder and those of two concentric bell covers.
2. Of a glass cylinder A, the inner surface of which is covered with tin foil a.
3. Of a glass bell cover B, the outer surface of which is covered with tin foil b.
The bell cover B and the cylinder A fit in the circular grooves of the ebonite stand E,
a distance of five millimetres separating the grooves. The sheets of tin foil a and b
are connected with an induction coil by means of conducting wires PN; attention
is called to the fact that the electricity is produced by an induction coil. The wire P
communicates with the positive pole of the induction coil. The wire N communicates
with the negative pole of the induction coil.
4. Of a class bell cover D insulating and covering the whole.
5. Between the grooves in which the cylinder A and the bell cover B rest, there
are openings e intended solely to allow the ozonized air to pass as fast as it is produced
into the nickel plated bronze bell cover G where it is stored.
6. The tube C which passes through the ebonite stand E brings the air, forced
along by a ventilator, into the bell cover B. This stream of air strikes against the
top of the bell cover B and is obliged to pass between the bell cover B and the
cylinder A. If at this instant the induction coil is set in operation, the inductive
electricity passes up the two wires P N, and the fluid, seeking its equilibrium, meets

page_text: with a resistance in the thickness of the glass, which causes the electricity to be
reconstituted in the form of feeble sparks on the surface covered with tin foil, that is
to say, on all that part of the outer surface of the cylinder A corresponding, to the
part of its inner surface covered with tin foil a; as also on all that part of the inner
surface of the bell cover B corresponding to the part of its outer surface covered
with tin foil b.
The oxygen of the electrified air then changes into ozone.
Having now particularly described and ascertained the nature of my said invention
and in what manner the same is to be performed, I declare that what I
claim is :
1. In an
ozone producing apparatus, the combination-of-an-ebonite or other
suitable stand E with a cylinder A, the interior surface of which is covered with
tinfoil a, and a bell cover B the exterior surface.of which is covered with tinfoil b,
substantially as described for the purpose set forth.
2. In an ozone producing apparatus, the combination of an ehonite or other suitable
stand E provided with openings in the part between the grooves in which the
cylinder A and the bell cover B respectively fit, such openings being intended to
convey the air into the bell cover G to be stored, a tube C, passing through the
cbonite or other stand, and a glass bell cover D covering the whole substantially as
described.
3. In an ozone producing apparatus, the combination of an ebonite or other
suitable stand E with a cylinder A, the inner surface of which is covered with
tinfoil a, connected by a wire N with the negative pole of an induction coil, and a
hell cover B, the outer surface of which is likewise covered with tin foil b, connected
by a wire P with the positive pole of an induction coil substantially as described, and
set forth.
