I 1 Claim. (01. 204-32) I This invention relates to an ozonator or device for converting the normal diatomic oxygen of the air into the triatomic form known as ozone. It is well known that ozone is much more active chemically than normal oxygen and that it serves as a much more activeoxidizer of carbon monoxide and other deleterious and unpleasant gases as well as bacteria.
One object of. the invention is to produce a device of small size capable ofozonizing a large volume of air. The principal use of such a device is in purifying the air in theatres, homes, public conveyances such as buses, street cars and railroad cars, garages and other places where human beings may be assembled;
Thedevice operates on the electric discharge principle by which oxygen may be converted into the ozone form by the passage therethrough of an electric discharge.- Another object of the invention is to provide means whereby a multiple spray of electric discharges 'of relatively low voltage may be produced instead f a single discharge of a higher voltage. To produce any appreciable quantity of ozone by a single discharge requires a voltage in the range encountered in the'discharge of natural lightning. By means. of the present invention a large number of much smaller dischargesare produced by a voltage on the order or 5000 volts and such discharges are obtained from a single source of -electricity.
Other objects and features of the invention will be understood from the accompanyingdrawing and the following description and claim:

a either type of unit. Fig. '7 is a side elevation of two of the assemblies used with the unit of- Fig. 3 is an elevational view of a grid used with the unit. Fig.4 is an elevational view of the same takenat right angle to thatof Fig. 3.; Fig.
of a portion of a grid which may be usedwlth Fig. 5. Fig. 8 is an elevatlonal view of a third type of grid. Fig. 9 is a wiring diagram of electrical connections.
The drawing illustrates several preferred forms er'li. The primary winding of the transformer rugated wires, the corrugations of which ex- In the-cover there are is connected by suitable conductors Hi to a plug I! which may be inserted in any socket furnishing alternating electric current at a commercial voltage and frequency,-for example, in ahousehold receptacle supplying 110 volt 60 5 cycle alternating current. If desired, a switch may be inserted in one of the conductors iii.
The ratio of the transformer is such as to provide a voltage on the order of 5000 volts at the secondary terminals, one' of which is connected by a conductor Hi to a stem IQ of the unit proper. The second of. the secondary terminals is left isolated or may. be grounded or connected to one of the primary lines I6.
The ozonizer unit shown' in Fig. 2 is mounted upon a cross piece which may be removably supported with the casing i0 and includes a pair of end plates 2| fixed to the cross piece 20 and insulated therefrom by insulation 22. The end plates 2| are secured together by bolts 23. Se- 0 cured to the end plates are upright insulation strips 24 between which there extend a bolt 25 and the stem i9.
Between the end plates there are located a number of assemblies each consisting of' a pair of plates 26, a pair of dielectric sheets 21 and a grid 28. The plates 26 are formed of a material capable of carrying an electric charge and are electrically connected by the bolts 23 but are otherwise electrically isolated by the dielectric sheets and the insulation 22. The dielectric sheets are of mica, glass or other suitable material of substantially uniform thick-'- ness; The grids are electrically connected by means of. the stem i3 which passes through a slot 29 in each grid and by the bolts'25 which pass through openings 30 therein.
' The grids 28, as shown in Figs. 3 and 4, consist of metal plates having a central opening 3| and two openings 32 at the upper and lower 0 ends, cross bars 33 being formed in the plates between said opening. Secured to the cross bars 33 and extending across the central opening 3| there are a plurality of relatively heavy cortend beyond the surfaces of the plate and engage the dielectric sheets in the assembly. The wires are preferably sumciently stout to pre.-' vent any appreciable yielding of the individual corrugations when the assembly is clamped together.
The several assemblies are clamped together between the end plates 2| by tightening the bolts 23. Spacers 33 are placed upon said bolts between the plates, 23 of adjacent assemblies to from each corrugation.
transmit the clamping force from one assembly to the next and to maintain the assemblies in spaced relation.
In the operation of the device alternating potential is impressed upon the grids 28 by the transformer. This potential is sufllclently high to cause an electric dischargethrough the dielectric sheets to charge the plates 26 at one extremity of the cycle and .to cause a similar discharge from plates to grids to discharge the plates at the other extremity of the cycle. Due to the fact that the dielectric sheets are of substantially uniform thickness, each corrugation of the wires 34 is uniformly spaced from its adjacent plate and. an individual discharge takes place Thus a large number of relatively small discharges are produced and said discharges are so distributed that they may ozonize as large a. volume of air as may be passed through the case I0.
In Figs. 5, 6, and 7, a modified form of unit is shown. In these figures like numbered parts have the same construction and function as in Figs. 1 and 2. Parts numbered in the 100 series have the same function but different construction than parts correspondingly numbered in the unit series of Figs. land 2. Plates I26 are supported on the bolts 23 and grids I28 are supported upon stem I9 and bolt 25. The grids I28 are formedv of a single sheet of corrugated and perforated sheet metal (Fig. 6) which engages the dielectric sheets I27 at a large number of points from which electric discharges may take 9 ace.
For securing the desired pressure'upon the various assemblies there-are provided leaf springs 26 interposed between the end plates HI and the adjacent plates I28 and leaf springs 31 interposed between the plates I28 of adjacent assemblies. Additional plates 38 are provided for abutment purposes between the springs 21.
A third alternative form of grid 228 is shown in Fig. 8. This consists of a rectangular frame 39 having a central opening 4|! across which there is stretched coiled springs ll which are of larger diameter than the thickness of the frame and so engage the dielectric sheets at a larger number of points from which electric discharges may take place.
The invention has been described in a number of preferred forms but the scope thereof is not to be limited by such descriptions. Variations in the details thereof may be made without departing from the scope of the invention as defined in the appended claim.
The invention claimed is:
An ozonator assembly including a pair of par-
