" ,f MELVIN J. NAPIER, OF AKRON, oHIo.

To all whom it may concern:

Be it known that I, MELVIN J. NAPIER, a

v V citizen of the United States, and residing at .Akron, in the county of Summit and State of Ohio,have invented a new and Improved Ozonizer, of which the'following is a s'p'ec1- fication. I v

This invention relates to devices for changing atmospheric oxygen from its common to the ozone state by means of electrical discharges, and its, object is to-provide an apparatus of this character which shall] have great capacity for the space occupied and which shall have a uniform output. A further object of-this invention is to provide means for uniting medicinal vapors with the oxygen in the ozone state and for permitting a discharge thereof at a predetermined point.

This invention consists in combination with a source of comparatively high tension alternatingcurrent, preferably a transformer, of a chamber andfa porcelain tube, mounted therein and having its ends extending through the walls thereof, of electrodes mounted within and on the exterior of the porcelain tube, and wires connecting the two to rent.

It further consists in hold the medicinal liquid which is to evapo-' rate and mix with the ozone.

It also consists in inclosing this chamber in a case to retain the ozone laden atmosphere.

It also consists in providing means where;

.by a stream of water or other liquid may be broken up and presented to the ozone so that the ozone may be taken up by the water.

It: also consists in the details of constructionillus'trated in the accompanyingdrawings and particularly pointed out inthe claims.

In the drawings, Figure 1 is a vertical longitudinal section of this improved joz onizer. Figs. 2 and 3 are sections on the lines 22 and 3-3 respectively of'Fig. 1. Fig.-

this source of. alternatingcur providing a novel contact for the inner electrode and in the trode. Fig. 6 is a section illustrating a sto for the inner electrode.

imilar reference characters refer to like parts throughout the several views.

I have found that when a tube of POICBI- lain is incased in an electrode and has mounted within it -a secondelectrode, both electrodes belng of less length than the por- Patented May 31, 1921.

celain tube, and when these electrodes are 1 connected to a source of alternating electrical current of; about 12,090 volts, that the atmosphere within the porcelain tube becomes highly charged with ozone. I have further found that when the inner. electrode is spaced throughout its length from the por celain tube so as f to lengthen the electric sparks between the electrodes,that the effect is increased. I have found further that the effect is .increased by placing a conical sheet-aluminum member within the inner electrode, although the reason for this is un-' known to me at present.

In Fig. 40f the drawings I have shown twosupports 6 and 7, which are preferably of good non-conductingmat'erial such as earthenware, glass, vulcanite, gutta perch'a,

' or indurated fiber. -Extending across and through proper openings in these supports and hermetically sealed therein is a tube 8 of porcelain' around the outside of which is a; metal tube 9, preferably of sheet aluminun, which constitutes one of the electrodes. This tube of aluminum may be continuous, or it may be split, as may be desired. With}- in the porcelain tube is a second electrode consisting of fa'shell ll having, a series of spacing .points 12 which maybe integral with the part 11.or mounted therein. ,jlWithin this shell 11 is a conical member 10 which is connectedat its larger end with the shell.-

The parts 10 .and 11 are removable so they may be cleaned and are preferably split. throughout their length so that the points 12 may bepressedagainst the inner wall of the pore ain tube 8 by the resilience of. the parts 10 and 11. A connecting wire 13 extends from-atransforiner 14; to this outer 'electrode 9 which: is preferably formed with a circumferential rib 15 to which this wire '13may be connected, while a second wire 16 also extendsfrom the transformer and is attached to a springcontact 1 7 which extends into the inner electrode 10 and contacts therewith. This contact'l? may be secured to the support 7 by means of a bolt 18. yIn order to position the inner electrode, Ihave provided a stop-19 which may be secured to the support 7 by means of the bolt 20 and which may have an'inturned end 21. When the inner electrode is pushed into the porcelain tube 8 (from the left in Fig. 4) it will slip beneath the contact 17 and engage the end 21, at which time it will be in alinement with the exterior electrode 9. Instead of the stop 19, a boss 8, shown in Fig. 6, may be formed on the inner surfaceof each tube 8 to limit the movement of the electrode 10.

The output of ozone of a mechanism of this character will depend largely upon the quantity of current delivered by the transformer and by the efiective areas of the electrodes. porcelain tubes 8 mounted in thesupport 6 and have shown the outer electrodes 9 ofthese various tubes connected by wires 22. I have also shownthe Wire 16 from the transformer 14 connecting to the branch wires'24, which branch wires extend through holes 25 in the support 7 and connect to the ends of the contacts 17.

The lower ends of the supports 6 and 7 rest upon shoulders formed on the

sides

27, 28 and 29 of the case and on the partition 30; All these joints are also hermetically sealed. It will be understood that thispartition 30'1'nay extend up to the top of the case, in which event the side 32 may-be omitted as'unnecessary; The side 32 is shown to extend up from the bottom '33,, and,

together withthe

sides

28 and 29, supports a series of'baflieplates' 35, preferably of glass, which are removable to permit cleaning, A supply pipe 36 extendsthrou h the topof the Wall 32 and a drain-piper, through the bottom. When the device is in operation and the atmosphere within the case i's'being heavily charged with ozone, water or Iother liquids may be permitted "to flow into the case through the pipe 36' and take up this ozone, the baffle plates 35' being corrugated in order tobreak up the liquid and present as much surface thereof as possible to, the charged atmosphere within the case. I

As-i dicated in the drawings, the supports 6 and 7 extend between the

side walls

28 and 29 of theca'se, but they are vof less height than these side walls. -Resting on the'top of these supports is a shelf or cover 39,.and the joints between this shelf, the

sides

27 and 28 and the supports 6 and 7 are all {hermetically sealed; Resting on this shelf 39- is a tray 40,.preferably of glass and having its upper surface provided with corrugations 41. Small quantities of medicinal liq uid, such as oil of eucalyptus, may be poured on this tray and spread'all over thesetcorru gations in a thin film to present an extended ,7

are of such size that electrodes 1011 may be freely drawn out from the tubes 8 so that the electrodes and the interior of these tubes may be cleaned. lVhen'air or other gas or vapor is forced into the case for any particular purpose, the majority of the openings 47 inthese plugs may be closed and supply pipes connected to those remaining. In this case a conduit will be connected to the cover at the opening 43 for the purpose of conducting the ozone laden air to a mask or nozzle for direct application of the ozonized vapors.

It is probablethat when the ozone mixes with the particles of oil that 'it'changes to nascent oxygen.

By closing the opening 43 in the top cover and all of the openings 47 but one, the ozone. may be drawn from the case for direct application. In this case air may be permitted to enter through the remaining opening 47 and'will flow through the several porcelain tubes .8.

Any-desired means may be employed to supply a primary currentto the transformer 14. In the drawings-two

wires

50 and 51 are shown. I prefer the number of alternations of current tobe from 600 to 1200 per second Grand 7 and around the tubes 8 with some hard insulating material; This prevents short-circuiting even if the device is submerged in water. 1
