To ll whom it may concern:

Be it known'that I, Smernmn Hnnm'a subject of the Emperor of Austria-Hun ary, residing at Ohicago, in the county of 00k and State of Illinois, have invented certain new and useful Improvements in Apparatus for Producing Ozone, of which the following is a specification.

This invention relates to an improved electrical apparatus for the production of ozone, and it consists in certain peculiarities of the construction, novel arrangement, and operation of the various parts thereof as will be hereinafter more fully set forth and specifically claimed.

One of the objects of my present invention is to furnish a com act and portable apparatus for the pro notion of ozone, which shall be of such constructionthat the currents of ozoniz'edair can be directed as desired, by-a slight change in the osition of the apparatus, and which shal be simple and inexpensive in construction,

strong, durable, and readily attached to' any suitable source of electric su ply for furnishing current of the require tension to the electrodes. 1

Another important object, is, to provide improvements in the construction of the electrodes, as well as, in the means for their support and novel arrangement, whereby the efiieiency of the apparatus will be augmented, and the deterioration of the electrodes, through oxidation, lessened, and besides, the formation of objectionable ases, such as nitrous oxid, prevented or re uced to a minimum.

A further object is to provide simple and efficient means for holdin the walls of the electrodes apart in paralle ism with one another, and one within the other, yet in such a manner, as to permit of the entire surface of one of them being exposed to the current of air as it is forced between said electrodes.

Other objects and advantages of the invention w1ll be disclosed in the subjoined description and explanation.

'As the present inventlon relates particularly to the construction, arrangement and mounting or support of the electrodes and their connectin parts,: I have shown said parts only in detail, and .Wlll hereinafter particularly describe the same, referring to the other parts of the apparatus m a general we only, it being deemed unnecessary to eit or show or describe the last mentioned parts in detail, as they may be of the ordinary or any preferred construction and their operation 1s well known.

In order to enable others skilled in the art to which the invention pertains, to make and use the same, I will now proceed tovdescribe it referring to the accompanying drawings in which Figure 1, is a view partly in section and partly in, elevation of an apparatus for proucing ozone, embodying the invention. Fig. 2, is a View of the Inlet end of the drum in which the electrodes are mounted showing a portion of the supporting arm for sald drum, Fig. 3, is an end view of the opposite or discharging end of the drum showing the electrodes mounted therein and illustrating a ortion of the arm which supports said dim, and Fig. 4, is an en'- larged rspective view of a portion of the puter e ectrode showin means thereon for holdin pieces used tor supporting said electrode on the envelop or closure of the other electrode.

Corres onding numerals of reference refer to li e arts throughout the difi'erent Views of the rawings. I V s The reference numeral 7, designates'a casing which may be of any suitable size, form,

and material, within which is located a transformer 8, of the ordina or any preferred construction, which is electrically connected to a motor or rotary converter,

- 9, as the case may be, in the usual manner by means of leads or conductors 10, and 11. As shown, the motor or rotary converter 9, is

mounted on the top of the casing 7, and

may have electrical connection through leaders or conductors 12, and 13, with a suitable source of electrical supply, not shown. Mounted on the shaft of the motor or rotary converter is a fan 14, which is driven thereby and is used to force currents of air through a drum 15, and between the electrodes, which-drum is mounted on a hollow arm 16, extended horizontally and then upwardl from the casing 8, of the apparatus. The rpm 15, is horizontally supported on the arm. 16, and has at its and adjacent to the fan 14, a flared portion 17, to receive and conduct the currents of air furnished by the fan, through the drum. Located in the drum 15, at about the juncture thereof with the flared portion 17, 1s a spider-frame 18, which is preferably made of fiber, and is fitted snugly in the drum, and may be held therein by frictional contact therewith, or otherwise. The central portion of the spider-frame 18, is rovided with a disk or member 19, from w ich are extended radially arms 20, which are united by a circular ortion or ring 21, which is likewise united y means of arms 22, to the outer portion or ring 23, of said frame, which latter ring or outer portion is fitted snugly in the drum as before stated. Secured to the inner surface of the disk or member 19, of said spider-frame is a metal socket 24:, which is in contact with a binding post 25, to which one end of a conductor 26, is connected, which conductor is extended through the hollow arm 16, into the casing 7, and electrically connected to the transformer. The socket 245, is preferably internally screw-threaded to engage an externally screw-threaded sleeve 27, which is secured on one end of a glass bulb or closure 28, which is extended horizontally within the central portion of the drum 15, and projects at its free end, to

near the discharging end of the drum.

As is clearly shown in Fig. l, of the draw-- ings, the bulb or closure 28, which may be made of any suitable material, but prefer ably of glass, has its rear end, or that end thereof adjacent to the spider-frame 18, reduced, and is provided near its other end with a series of inwardly extended projections 29, which projections are preferably made by indenting the bulb or closure 28, on its outer surface, thus. forming corresponding projections on its inner surface. Located within the bulb or closure 28, is a metal stem 30, which is secured at one of its ends so as to contact with the socket, 24, thus forming electrical connection through said socket and the binding post 25, with the conductor 26, and transformer. At its inner end, the metallic stem 30, isvprovided with two forwardly disposed metal arms 31, and 32, which, as is clearly shown in Fig. 1, of the drawings, extend in opposite directions from the stem 30, and then forwardly in parallelism with one another. Mounted on the arms 31, and 32, and encompassing a portion of the stem 30, is a tubular electrode 33, which is preferably made of aluminum, and is supported on the stem 30, by means of the arms 31, and 32, which are disposed diametrically opposite each other, within and against the inner surface of the front portion of the electrode 33, as will be clearly understood by reference to Fig. 1, of the drawing. When thus mounted, the front end of the electrode 33, will rest against the projections 29, of the bulb or closure 28, thus holding the main art of the electrode 33, at a slight distance om the bulb or closure, which said electrode is referably sealed in vacuum within said ulb. Located in the front or discharging portion of the drum 15, is another spiden frame 34, which includes two concentricrings 35, and 36, united by radially disposed arms or portions 37, which afford spaces for the passage of air. The inner ring 35, is provided on its inner surface with a series of inwardly extended projections 38, which are. used to rest against the front portion of the bulb or closure 28, so as to assist in supporting the same within the drum. Surrounding the bulb or closure 28, is another electrode 39, which is preferably made of aluminum and is. electrically com nected by means of a conductor 40, with the I transformer, which conductor is extended through the hollow arm 16, and into the casing 7, which incloses said transformer.

The electrode 39, is provided at each of its ends with a series of inwardly extended lips 41, which are arranged in pairs, and are preferably formed by being punched out of the material of which said electrode is made. inserted between each pair of the lips 41, is a distancing piece -12, of fiber or other insulating material, which pieces contact with the outer surface of the bulb or closure 28, so as to hold the electrode 39, at a slight distance therefrom, yet in parallelism with, the same as well as with the electrode 33, which as before stated, is inclosed by said bulb.

' From the foregoing and by referenceto the drawings, it will be readily understood and clearly seen, that when the apparatus is operatively connected, to a suitable source of electrical supply, the fan or blower 14, will be rotated, thus causing currents of air to be forced. through the drum 15, and between the electrode 39, and the bulb or' closure 28, for the electrode 33, which air will be accordingly ozonized and discharged at the outlet or discharging end of the drum.

Having thus fully described my invention what I claim as new and desire to secure by Letters-Patent is- 1.
