To all rwhom it may comier'nf:

Be it known that I, DAVID S. HENNEY, a citizen of vthe United vStates, residing at Newark, in the county of Essex and State of- New Jersey, have invented certain new and useful Improvements in Ozonizers, of which the following is a clear, full, and exact description.

The object of this invention, is to .provide an improvedO device for the production of 1 ozone from the atmosphere, whereby a simple, efficient and economical device may be produced for general hospital and other use.

Afurther object is to provide a device which is readily attachable and detachable in place.

In carrying out my invent-ion, I make use of a. double Wall device formed of similar glass cylinders perforated with holes near their ends, and between the holes and the end of each cylinder, the cylinder is reduced in diameter. One of the cylinders is smaller than the other, and shorter, and is inserted in reverse posit-ion into the larger, the end being plugged to prevent egress of air, and an electrode suspended within the smaller cylinder. The two cylinders are prepared as in the usual manner with a foil coating, the smaller cylinderohaving the foil on the inside wall; vthe larger cylinder has the foil on the outside. The foil on the outside cylinder is connected with one pole of the high potential alternating current, while the electrode withinv the smaller cylinder is connected with the other pole. In order to make the device easily attachable and detachable, I provide a threaded bushing at the reduced diameter of the outer cylinder, that it may be threaded into place in a socket of similar construction, and I proy vide a metallic button connected with the electrode, which may be contacted with by a spring-pressed contact block, such contact block being adapted to be lifted upon afrotation of the ozonizer in its socket. v

The scope of my invention will be pointed out in the claims.

In the accompanying drawings, Figure 1 is a vertical central cross section'of my improved device, taken on line 1-l, Fig. 2. Fig. 2 is a horizontal sectional plan taken on llne 2 2, Fig. 1. Fig. 3 is a view on reduced scales, showing outside side elevation of my blower.

As shown in the drawings, a socket 1 of improved device connected with a insulating material, preferably porcelain, is providedwith an interior metallic threaded shell 2, to which is connected one pole 3 of a high potential circuit of alternating eurrent. A pipe 4 connected to the centrally open socket leads to ablower 5, which supplies air to the device for purposes well known and understood .in this art. y The other terminal or pole-6 leads to a bar 7, in which is slidably mounted aJ rod 8, having a contact block 9 at one end, the contact block held in the position of Fig. 1 normally by a spiral spring 10 surrounding the rod 8. A pin 11 may be supplied to prevent the rod from leaving the bar 7 when no ozonizing device is in place.

The ozonize'r itself consists of a double wall device made up of 'two similar cylinders, eachA having a" reduced end portion,

and each provided with 4holes in its wall-.-

,portion 13, to which there is secured by suitable` cement 14 a threaded shell 15 adapted to engage the shell 2 in the socket 1. A strip of copper 16 is secured to the shell 14, and is passed from the reduced portion of the cylinder 12 to a short distance above the corner joining the cylinder proper with the reduced portion; A layer of tin foil 17 is then secured around the major part of the cylinder 16 in contact with the copper strip 16. Around the base of the larger cylinder 17 are anumber of apertures or holes 18 for a purpose hereinafter described. The cylinder 19 of glass is formed with reduced portion 20, which is inverted in position with its lower edges in contact with the glass of the outer cylinders at one end,

and is provided with holes 21 near its upper.

end. Tin foil is secured to the inside of this cylinder, as shown at 22. -A terminal 23 in the form of a wire provided with b rush members 24 in contact with the'tin foil, is

suspended from an insulating plug 25 .se-v

los

blast, thus securing ozone in the improved manner known to the art Without danger of puncturing the Walls. It will be apparent that by the mere insertion of the ozonizer by a threading motion into the socket, and permitting the spring l0 to depress the contact block 9, that the apparatus can thus be readily attached, and detached, to the poles.

I claim as my invention:

l. The herein described apparatus for the production of ozone, consisting of an outer cylinder, and an inner cylinder, the outer cylinder having one end'of reduced diameter, the inner cylinder resting With its open end in contact With the outer cylinder, means for sealing the two cylinders at one end, both cylinders being open for the ingress of air at the other end, openings in the inner cylinder communicating therefrom to the interior of the outer cylinder, openings from the outer cylinder communicating With the outer air vand means for securing an electrical discharge Within the device.

2. The herein described apparatus for the production of ozone, consisting of an outer cylinder, and an inner cylinder, each cylinder having one end of reduced diameter, the inner cylinder resting With its open end in contact Withy the outer cylinder, means for sealing thetwo cylinders at one end, both y cylinders being open for the ingress of air at the other end, openings inthe inner cylinder communicating therefrom to the interior of the outer cylinder, openings from the outer cylinder connnunicatingwith the outer air, such openings being at opposite ends ot the apparatus, and means ior securing an electrical discharge Within the device, theouter cylinder' being provided with a base adapted to contact with a receptacle in combination with a receptacle to receive said base.

The herein described apparatus for the production of ozone, comprising two similarly shaped open-end glass cylinders of diti'erent diameters, each cylinder 'provided other end of the device,v and an electrode within the inner vessel.

Signed at New York city, New York, this 29th day of July 1910.
