T O all whom t may concern.'

B 'it known that I, VVILLLAM Gr. LINDE waukee-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 apart of this specification. y

The invention relates to ozonizers and more particularly to an ozonizer for generating ozone from a continuously flowing stream of compressed air.

One of the objects of this invention is to provide a construction in which large amounts of compressed air may be ozonized withoutproducng high temperatures which aect both the production of ozone and the electrodes.

further object of the invention is to provide an ozonizer in which the ozonizing elements consists of a plurality of flat plates between which the compressed air to be ozonized is passed in an ecient manner.

A further object of the invention is to provide an ozonizer in which the ozonizing air is given a free passage through the ozonizer and at the same time is brought into the zones of electric discharge so as to be ediciently ozonized.

The invention further consists in the several features hereinafter set forth and more particularly deined by claims at the conclusion hereof.

Ir the drawings: Figure 1 is a vertical V'sect .oral view through an ozonizer embodying the invention; Fig. 2 is a plan view of the ozonizing apparatus with the coi/'en removed and parts broken away; Fig. 3 is a detail sectional view taken on the linegof Fig. 2; Fig. 4 is a vertical sectional view showing an ozonizer similar to Fig 1, ein, cept for the outer casing-Jl Fig. 5 is a section taken on the line 5 5 of Fig. 4;; Fig. 6 is a section taken on the line 6-6' of Fig. 1,

Referring to Figs. 1 to 3 inclusive, the numeral 6 designates a rectan ular metal box or'outer casing provided with a removable metal'cover 7 secured to flanges S on the box by bolts'9 to form an airtight compartment. An inlet 10 conducts compressed air into the upper end of one side of the casing and an outlet 11 atthe upperend ofthe opposite side of the casing allows the ozonized air to pass out of the ozonizer through a pipe (not shown) to the place of use. An air compressor 12 ofany suitable construction provided with inlet and discharge valves 13 and 14 delivers compressed air to a pipe 15 communicating with the inlet 10.

Within the gasing 6 is a frame of insulat ing material, such as wood, consisting of side frame members 16, 17, 18 and 19 suitably eonnected together to form a unit which may be readily placed in or taken out of the casing. The members 16 and 17 are preferably spaced from the sides of the outer casing adjacent thereto. The memberI Specification of Letters Patent, Patented Dec.I 1920,

taining the inlet 10 to form with the casing and member 16 and 17 a channel 2Q and its lower end 21 terminates at a distance above the bottom of the casing. The upper end 22 of the member 19 terminates at a distance from the upper end of the casing to form a passage for the flow of ozonized air through the outlet 11. The lower portions ofthe members 16 and 17 and the bottom of the casing form a channel 23 `communicating with the channel 2O and extending from its inlet at the end 21 of the member 18 to the member 19. The channels 20 and 23 form a single channel for conducting the compressed air from the inlet to Ozonizing elements 24.

The ozonizing elements are in the form of Hat plates in which a perforated metal plate orfne mesh wire screen 25 is embedded in or secured between two plates 25 of any dielectric material such as glass. Where plates are used they are secured together by a binder 26 of insulating material. The screen. 25 is preferably spaced from the margin of the plates and a conductor 27 leads @from one corner to a contact 28.

Formed integahwith or secured to the frame members 16i`1dlx17 are racks of insulating material, such as wood, having' 32 secured to the members 29 having resilient contactngers ardaptedftoibeem 1 outlet ll..

Tl'iu the current is on, the dis :barge taires a een the elements and the air pessing through the spaces between the elements subject to this discharge and Vthe oxygen therein is converted to ozone The racks 29 terminate at a distance from the cover 7 and the members 16, 17 and 13 have an airtight .lit `with 'the cover so that a space or ehaniber is .'orined above the plates through which the. ozoniaed air passes to the The Contact plates 3&2 are disposed on. the same horizontal plat e s the 1 m A1 '1 lower euu il ot the member l5 :um the compressed passes from the inletI l() und througu the ehennels@ and and then directly up through the passages between the spaced ozonizing elements Where it is subjected to the electric discharge and thence through the space above the @ionizing elements. By means ot the above free circulation of the zur through the ozonizer., the elements are kept cool and a large quantity oit ozonized may be efiiciently generated.

The air is admitted to a channel 55, r'ornied iu the box, by means of a nozzle 56 extending down through a fianged opening 57 in the shell and into the box.
