OZONIZER.

A Tofall whom it may concern:

Be it known that I, ErrmAiM D. Kiers,

i' a citizen of'the United States, residin 1n sion,

the city, county, and-State of New ork,

have invented certaln new and useful Im;k provements in Ozonizersg. and I do hereby declare the followin j to be a full, clear, and

exact description o the inventionsuch as will enable others skilled in' the art to whichy it appertains to make and use the same.

This invention relatesl to ozonizers of the type employing a discharge of a-high tenelectric current across a narrow gap between two electrodes. The object of the invention is to provide an improved construction for an ozonizer of this type whereby simplicity'of construction, ease of assemblage and low cost of manufacture are attained, "and in which provision is made for the circulationof air in such a way as to guard a ainst over-heatin paratus. T e invention is use l in'ozonizers for various purposes, but is of special utility in medicinal apparatus, including an ozonizer and a receptaclev for a substance like pinene, with which ozorle combines to form a pinene ozonid vapor.

I have illustrated the preferred embodiment of the invention in the accompanying drawings, in which Figure 1 is a central,

vertical section of the ozonizer; Fig. 2 is a j plan view, and Fig. 3 is a transverse section on line 3-3 o-f Fig. 1f

Referring to these drawings, the ozonizer is built up upon a tube 4 which may lbe a tube of metal such as aluminum servin as oneof the electrodes of the ozonizer. T de# sired, however, this tube may be made of some moldable, insulating material such as bakelite and may have asheet of metal applied to the interior thereof. The tube, whether of metalor of insulating material, is provided with a lflange 5 at its upper end which rests upon a support 6 to sustain the entire ozonizer in position.` The lower end of the tube is open lbut the upper endis closed by a disk 7 of insulating material, preferably glass. This disk bears-upon the upper surface of the flange 5Ion tube 4 which flange bears uponthe upper surface I a ring 8 of insulating material is mounted upon the support 6 as shown, such size that it fits snugly within the 8.

Within the tube 4 is a glass cylinder 9, on the interior of which is ametallic :film or of the ap.-

and the glass disk 7 is of coating l0.- This cylinder or` bottle is mounted within the tube 4 with its cylindrical wall separated from the wall-of the tube by a narrow space which may be about onesiXteenth of an inch wide. To facilitate accurately positioning the cylinder 9 within y the tube 4, the latter is provided with a plurality of internal projections or spacers 11. The lower series of spacers 11 coact with the lower-closed end of the cylinder 9 so `as to limit the downward movement of the cylinder through the 4tube 4 and both series ofv projections 11 serve to position the cylinder Y accurately so that it is concentric with the tube 4. The narrow space between the cylindervand tube is therefore of the same width at all points and the projections 11 of the two series are spaced yapart so that they do not restrict the flow of air through this nar-` row space between the tube and cylinder.

The glass disk 7 serves as a closure for the upper end of the tube 4. The end ofthe cylinder@ adjacent to this closed end of the tube is open, as shown in the drawing. Y The opposite end of thecylinder is closed, as

stated above, and the end of the tube adja-.

cent to this closed end of the cylinder is open. Provision is made for supplying air to the interior of the cylinder at a point adjacent to the closed lower end of the cylinder. For this purpose a metallic tube 12 is provided passing through a central opening in the glass disk -7 and extending down entirely throughthe cylinder 9 to a point adjacent to the closed lower endvthereof. Provision ismade for guarding against the escape of air around the tube l2 at the point where it passes through the disk 7. `This is preferably done by making thetube 12 in sie two parts which are joined together by coacting threads at this valve being provided with an operating handle 17. The tube 4, preferably made of aluminum, constitutes one electrodeof the ozonizer. Electrical connection is made to itl preferably b providing a leaf spring 18 in a recess in t e support 6 so that the end of the spring will be engaged by the ange 5 on the tube 4 'when the tubeY is inserted in position. This spring 18 has a stud 19 on it n andadjacent to them are handles 255by, Y .whlch. the rmgl may berotated about its '18,.- depresses the latter, 50

1 lowered through adapted to be engaged byla suitable con- 'necting device on the end of the wires eX- tending from the source of supply. The other electrode consists of the film or coating 10 of metal upon the interior of the glass cylinder or bottle 9; rlhis lm maybe a ilm of metal applied' to the interior of the cylinder in the form of a paint. Preferably, however, the film consists of a thin sheet of metal, as aluminum., rolled to a cy?A lindrical form and then inserted within theopen end of the cylinder 9. The spring tension of the metal will serve to hold the sheet in position within theA cylinder l 9 closely against the glass wall of the cylinder. Electrical connection is made to this film or sheet 10 through the metal tube 12. For this purpose a spring arm 20 is secured upon the tube 12 and bears upon the inner surface of the coating or sheet 10. On the tube 12 above the disk 7 is a stud 21 to receive a connector on the other lead wire of the circuit.

ln order to hold the parts rigidly in posi-y t1 on and prevent" escape of air around'the disk 7,-a'clamp is .provided for holding the `disk securely and .pressing it down upon rthe iange ofthe tube 4, .This clamp may be 1n theform of ay metallicring 22, which,

'when not under restraint, assumes a position in which two diametrically opposite points thereon are displaced in thedirection of the action of the ring from two other diametr1cally opposite points equally distant therefrom. The ring 8 has two brackets 23 secured theretohat diametrically oppositel pomts and the r1ng22 has notches y24 the-re- -1n through lwhichl the ends of the brackets in lhese notches 24 'are 'logf pomts of the clamping ring 2?, may pass when insertingthe clamp ring 1ny position.' catedat the low axis.

The dished clamping ring 22 is then lowered within the ring 8 until the notches 24 pass over the ends of the brackets 23 and then the ring is turned by means of, the handles 25 until the high points on the ring are carriedunder the ends of the brackets 23 and' are vof ozone. the opening in the'sup- 'I ily by merely disconnecting the wires, turning the clamping ring 22 throughv 90 so as to permit its withdrawal upwardly 4, around the tube 12 and then withdrawing Y one ormore of the parts 12, V 9, and 4."

lWhen the apparatus is in operation, air is supplied by the blower 13' through the tube 12, its flow being regulated by thel i .valve 16. The air so supplied takes a tortuous path in flowing through the ozonizer.

lt passes. downwardly through the .tube 12 to the lower closed end of the cylinder 9 and then flows upwardly through ,the cylinder to the upper open .end thereof... Then it passes downwardly through the narrow space between the cylinder and', the tube 4 to the lower open end ofthe/tube 4. This end of tube 4 leads to the point of use of the ozone and it may be contracted as may be deslred Vfor the purpose 4of establishing and maintaining a pressure. While'the air is Howving through this passage, high .tension alternating current is supplied to the wires -clonnected to the studs 19 and 21.- The cur rent flows from the stud 21 through tube 12 and -arm`20flto the film 10 onl the interior ofthe cylinder 9 and then passes across the gap vbetween the electrodes 10 and 4 and then out through the contact 18 and stud 19. rllhe high tension passage across the gap between the electrodes 10 and 4 results n the generation (if ozone and the current of air throughthisspace'carries the ozone generated "out through the discharge 'out- -let of the apparatus andv continually renewslthe supply of airfor the generation Furthermore, the urrent of ,air passing back and forth through the ozonizer.

It'will bernote/d that lthe ozonizer as a Whole'v lis of simple construction and consists of but few parts which may be readily assembled. When assembled, all o the pants are held rigidly in position and are protected by the tube within which all of the delicate parts are mounted.
