OZONE PRODUCING DEVICE Filed June 26, 1929 2 Sheets-Sheet 1 Patented July 1, 1930 UNETED STATES PATENT OFFICE DEAN W. DAVIS AND THOMAS M. HARDY, OF PENDLETON, INDIANA, ASSIGNORS TO NATIONAL LABORATORIES CORPORATION, OF PENDLETON, INDIANA, A CORPORA- IIOll' OF INDIANA OZONE-PRODUCING DEVICE Application filed June 26,
This invention relates to the art of producing ozone and particularly to portable units adapted to be operated in private homes, oflices, dining cars and the like where purification and deodorizing of the air is desired. The principal objects of the invention reside in the provision of a compact unit designed to use the minimum of current in proportion to the ozone produced; that may be absolutely safe in the hands of all users regardless of the location of the unit and that may be subject to long life and not affected by the mechanical action of the ozone.
Other objects reside in the formation of the condenser and also in the means of locating and holding it in position in the unit to permit a current of air to pass readily there through and to permit easy and quick assembly of the various parts.
These and other objects will become apparent in the following description of the one particular form of the invention as now best known to me as illustrated in the accompanyin drawing, in whichig. 1 is a fragmentary top plan view of a unit embodying our invention;
Fig. 2, is a fragmentary side elevat on;
Fig. 3, a horizontal transverse sect1 on on the line 3-3 in Fig. 2;
Fig. 4, a vertical section through the condenser on the line 44 in Flg. 3;
Fig. 5, a wiring diagram; and
Fig. 6, a bottom plan view of the unit.
Like characters of reference indicate like parts throughout the several vlews 1n the drawings.
We form a transformer core 10 of the laminated type here shown as rectangular n shape, on one side of which we place a primary winding 11 and on the opposite side the secondary winding 12. The core 10 is spaced substantially centrally between an upper plate 13 and a lower plate 14 by the studs 15, one at each corner. Within the space bounded by the sides of the core 10, we position a condenser of the following description.
We first form one side of the condenser by taking a number of U-shaped members 16, 17, and 18 each with spaced apart vertically positioned parallel plates and nest t e three 1929. Serial No. 373,808.
members together as indicated in Fig. 3 to have the webs interconnecting the respective plates of each of the members compressively held together by a bolt or rivet 19 passed centrally therethrough to finally secure the three pieces so arranged against an insulating board 20 which has the legs 21 and 22 bent around normal to the board and spaced outwardly from the plates of the member 18. The other side of the condenser is formed in exactly the same manner by employing the three U-shaped members 23, 24 and 25 to have the webs between the plates compressively held together by the rivet 26 also securing the assembled three members compressively against the insulating board 27 which has the legs 28 and 29 bent around into the same planes as those of the legs 21 and 22.
The last named assembly of the members 23, 24 and 25 is positioned on the board 27 so that when the two sides of the condenser are assembled the plates of those members will extend between and lie equidistant from the plates of the members 16, 17, and 18.
All of the plates of the various members are provided with a plurality of studs 30 projecting from each of their vertical faces. A sheet of insulating material 31, preferably mica, is bent to lie along one of the vertical faces of each of the plates of the members 16, 17 and 18 and to pass around the extreme outer end and thence backwardly along the other vertical face. By placing one of these insulators 31 about each of the plates of those members, an insulated partition is thereby positioned between each of the plates of the members 16, 17 and 18 and the next adjacent plates 23, 24 and 25; The height of the studs 30 and the thickness of these insulators 31 are such that when completely assembled the insulators will be contacted by the studs of the plates and the plates will be held thereby parallel one to the other.
Rectangular holes are formed in the metal plates 13 and 14 to receive therethrough the insulating boards 20 and 27, the height of both of these boards being such that they will extend substantially through the plates 13 and 14 to have their outer ends practically flush with the outer faces of the respective plates. Now to secure the two boards 20 and 27, we place the side insulating boards 32 and 33 down between the boards 20 and 27 against the inner faces of the respective legs of the two boards, as indicated in Fig. 3, the lengths of the boards 32 and 33 being sufiicient to compressively engage the boards 20 and 27 against the sides of the holes through the plates 13 and 14. The width of the holes through the plates 13 and 14 are such that when the boards 32 and 33 are placed into position as above indicated, the legs 21 and 28 will be pressed outwardly against the one side of the hole and the legs 22 and 29 against the opposite side, and will compress all of the insulators 31 on the plates therebetween one against the other so that the insulating members are frictionally held in vertical position against the studs of the plates with intervening air spaces past the studs between the plates and the insulators 31.
It is to be noted that the plates from the respective sides of the condenser terminate at some distance back of the webs of the opposite members.
The condenser as above described substantially fills the area between the windings 11 and 12 and the sides of the core 10. The boards 20 and 27, in fact, bear against the-inner sides of the core The assembly of the transformer with the condenser therein is positioned within a housing 34 as indicated in Figs. 1 and 2 to have the plates 13 and 14 fitting against the vertical walls therearound and the entire space between these plates is preferably filled with an insulating compound 35 which may be poured in to effectively seal the two windings and the core 10 against any oxidizing action from without. The plate 13 is spaced below the top of the housin 34 and the plate 14 is at a distance above t e bottom of the housing. The studs 15 project downwardly from the plate 14 through a lower cover plate 36 with spacers 37 therebetween and extend on below the plate 36 to carry the buttons 38 on which the housing rests. The p late 36 is provided with a plurality of perforations 39 therethrough at each end, the plate being entirely closed across the area under the condenser.
The top side of the housing 34 is depressed at each end and has a number of louvers 40, here shown as three in number in each of these depressions, so arranged that articles such as wires or the like may not readily be inserted therethrough to reach the plates in the condenser.
Thus it may be seen that there may be a passage of air upwardly through the holes 39 in the plate 36 across and upwardly vertically between the plates of the condenser and thence laterally and upwardly through the louvers 40.
By placing the terminals of the, w'nding 11 in circuit with a suitable source of pulsating or alternating current, a current is induced in the secondary winding 12 to build up charges of opposite characters on the respective plates in the condenser to have an electrical discharge created thereby for producing the desired ozone.
To some persons, the odor produced about a source of ozone is disagreeable, and to overcome that objection, we insert a piece of absorbent material 41 on the lower plate 36 over which the air current passing from the holes 39 into the condenser may pass. A hole 42 is made in the plate 36, through which a few drops of some volatile, pleasing odorous substance, such as oil of pine, may be dropped by turning the housing 34 upside down, to be absorbed by the material 41. Now with the housing 34 returned to its normal upright position, the air current passing over the mate rial 41 will pick up the volatilized substance and hence carry it on into the room.
