ANTHONY LHMAN, OF IPHIIJDLPHIA-, PENNSYLVANIA, .ASSIGNOR TO W. W. GIBBS, OF PHILADELPHIA, PENNSYLVANIA.

QZONIZER.

Application led January 26, 1909. Serial No. 474,250.

To all whom 'it may concern:

Be it known that I, ANTHONY LOHMAN, a citizen of the United States, and a resident of Philadelphia, in the county -ofPhiladelphia and State of Pennsylvania, have 1nvented `certain new and useful Improvements in Ozonizers, of which the following.

is a specification.

The principal object of the present invention is to provide a simple, compact, reliable and 'efficient ozonizer which 1n operation shall be comparatively free from accidents of allkinds and shall produce a relatively large percentage of ozone and economically apply the same.

Theinvention will be claimed at the end hereof, but will first be 'described-in connection with the accompanying drawings illus- `trating one embodunent thereof, and in whic -V Figure l, is a perspective View of an ozonizer embodying features of the inven# tion. Figs. 2, and 3, are respectively a horizontal and a' transverse section thereof, and F ig. 4, is a detached View illustrating features of construction.

There is a series of dischargers 1, 2, 3, 4: Each of these dischargers consists of a fiat imperforate plate and the invention is not -limited to the number of such plates.

Aluminum is the best material from which to make these plates. Between each pairof plates of the series is interposed a dielectric 5, which may vbe of any appropriatematerial; micanite being an example, and these dielectrics consist of at plates whichjare larger than the dischargers and extend be` yondvthe latter all around the edges thereof; the purpose of this is to oppose any tendency that may arise for the discharge to jump from discharger to discharger around instead of through the dielectrics.

6, are insulating strips, as of glass, which are interposed between the faces of 4each discharger and the adjacent dielectric; These strips maybe arranged at the margins of the dischargers and also intermediate of the margins. In the drawings they are shown only at the margins, because the type of dischargers chosen for illustration is comparatively small.

Alternate dischargers as 13, etc., are connected to one terminal 7, and the intermediate dischargers are connected to the -other terminal 8. This can be accomplished by providing the` dischargers with lugs Aor other terminal connections which are electrically connected with' suitable terminals or binding posts.- The terminals 7 and 8, are connected'to the opposite sides of an appropriate alternating current circuit so that at each reversal of the alternatin ycurrent there is a discharge from onesi e or the other of the discharger, thus the discharge considered as a whole, is practically continuous. 'Ihey pile or stack of "dielectrics and dischargers is arranged in a suitable housing 9, provided with 'an `inlet 10 and an outlet 11 for air or other gas to be treated by the apparatus. It is suflicient for the purpf ses of description to refer to the treatment o air.

As shown the dielectrics extend from side to side of the housing or casing, but not to the ends thereof, so that spaces l2 and 13 are left at the ends thereof. In the space 12, the terminal connections are arranged.

In use air entering' at 10, passes between the dielectrics and dischargers and reaches to the discharge which takes place between the dischargers and is ozonized. While I lhave not shown means for cooling the apparatus it is evident that the housing or case 9, can be inclosed in a water jacket or otherwise cooled. f

What I claim'is:

l. An ozonizer comprising the combination of im erforate plates constituting dischargers, ielectrics consisting of plates interposed one between each pair of dischargers with space between and extending beyond the edges of the same in all directions, insulating strips interposed between the faces of each discharger and the adjacent dielectric toyatord air passages, a casing 'inclosing said parts and tted to the sides of the' dielectrics and extending beyond the ends' of the same to form chambers, an inlet and outlet for the chambers, and alternating current connections one side of which is connected with the alternate dischargers and the other side with the intermedmte dischargers, substantially as described..

2. An ozonizer comprising a casing having at one end an inlet and at the other end 4an outlet, dielectrics consisting of plates eX' the space 13.' In doing this it is subjected stopping short of" the ends thereof to proymediate dischargers in another series, sub- 1o .vide chambers, dischargers .interposed one stantially as described.

between each air of dlelectrics with space In testimony whereof I have hereunto between and o lless area than the latter and slgned my name.

A .consisting of irnperforate plates provided ANTHGNY LOHMAN with terminals, lnsulating strips interposed between the dischargers and dlelectrics, and Witnesses:

electrical connections .connecting the alter- FRANK E. FINCH, nate dischargers in one series and the inter- A. B., SmUGH'roN.
