Specification of Letters Patent.

Patented Now. 8, 1921.

Application filed April 25, 1919. Serial No. 292,740.

T 0 all whom it may concern:

Be it known that I, \VILLIAM G. LINDE- MANN, a-citizen of the United States, and resident of Milwaukee, in the county of Milwaukee and State of Wisconsin, have invented new and useful Improvements in Ozonizers, of which the following is a description, reference being had to the accompanying drawings, which are a part of this specification.

The invention relates to ozonizers and has for its general object to improve upon devices of this character by providing elements which may be readily repaired or replaced and which may be manufactured at low cost.

A. further object of the invention is to provide unit discharge elements in the form of removable fiat plates which may be readily cleaned.

A further object of the invention is to provide ozonizing elements having a very efiicient discharge.

A further object of the invention is to provide an oz'onizing apparatus in which an interposed element receives a double discharge from adjoinin elements.

The invention furt er consists in the sev eral features hereinafter set forth and more particularly defined by claims at the conclusion hereo In the drawings: Figure 1 is a plan viewof the device embodying the invention with the cover removed; Fig. 2 is a section taken on the line 2-2- of Fig. 1;- Fig. 3 is a sectional viewof one of the elements in which the conductor is embedded in dielectric material.

Referring to Figs. 1 and 2, the numeral 4 designates generally the ozonizing elements. Each of these.elements consists of a fine mesh screen of wire 'or other suitable conducting material interposed between two plates 6 of suitable dielectric material, sucli as glass, the screen being spaced from the edges of the glass plates and having a conductor 7 leading from a corner thereof to one of the corners of the plates. The screen is held between the plates and the plates are bound together by means of a marginal frame 8 of insulating material secured to the plates by a suitableinsulating binder. In-

from embedding the screen in the material as by molding it therein and consequently dispensing with the binding frame 8, this element is similar to that reviously described, the screen being similar y located in the element and being provided with a conductor wire similar to the wire 7. Each of the elements is provided with a contactshoe 10 at a corner thereof, which is connected with the screen by the conductor 7. Where the screen is embedded in the dielectric, the contact shoe may also be partially embedded in the dielectric or may be exteriorly secured thereto. While the flat plate construction is preferred because of the ease of cleaning the units, the invention is not to be limited thereto as the units may be of various shapes, such as concentric tubes of dielectric material with the conductor disposed between the tubes.

The units are disposed in a casing 11 provided with a removable top cover 12 and with grooved racks 13. The ozonizing units are slidably mounted in the racks so as to be readily removable therefrom for the purpose of repair, cleaning or replacement. The electric current is conducted to alternate units from a conductor 14 through contact buttons 15 in circuit with the conductor 14 and adapted to be engaged by theshoes 10 of alternate units. The circuit is completed through the other units which have their shoes contacting with contact buttons 16 connected to a return conductor 17. Thus, when the current is on, the discharge takes place from the element A to the element B and also from the element C to the element B. The screen may be of any mesh, but, of course, the finer the mesh, the more eflieient is the discharge as the screen has the effect of creating innumerable discharge points between adjoining plates, so that the .air passing through the space between the plates is efiiciently ozonized. As shown in ig. 2, the casing 11 has an air inlet 18 and an outlet 19. Air may either be introduced through the plates by forcing it under pressure through the inlet 18 or it may be drawn into the casing and through the plates by suction exerted at the outlet 19.

It is to be understood that this invention is not limited to any specific form or arrangement of parts except in so far as said limitations are specified in the claims.

What I claim as new and desire to secure by Letters Patent is: I

1. In an ozonizing apparatus, an element comprising a screen conductor provid/ed with a dielectric covering, the covering exitending beyond the screen to form a dielectriqborder, a contact secured to the side of the element, and a conductor connecting the screen with the contact and covered by the dielectric.

2. In an ozonizing apparatus, an element comprising a piece of dielectric material having a plain surface and a metallic screen conductor embodied therein at a distance from its outer edges and having a lead extending to an outer edge thereof, and a contact shoe secured to said lead at the outer edge of said surface.

3. As an article of manufacture, an element for ozonizing apparatus comprising a pair of glass plates, a screen conductor disposed between the plates and spaced from theedges thereof, a frameof insulating material for binding the plates together, a contact shoe secured to the frame, and a conductor between the plates connecting said shoe to the screen.

4:. As an article of manufacture, an element for ozonizing apparatus comprising a pair of glass plates, a metallic member disposed between the plates and spaced from the edges thereof, a frame of insulating material for binding the plates together, a contact shoe secured to the frame, and a conductor between the plates connecting said member to the shoe.

, In testimony whereof, I afiix my signature, in presence of two witnesses. V
