OZONIZER Filed Sept. 25, 1928 Patented Aug. 9, 1932 UNITED STATES PATENT OFFICE ALBERT E. EVANS, OF CLEVELAND, OHIO, ASSIGNOR, BY MESNE ASSIGNMENTS, TO THE COROZONE'COMPANY, OF WILMINGTON, DELAWARE, A CORPORATION OF DELAWARE OZONIZER Application filed September 25, 1928. Serial No. 308,164.
This invention relates to ozonizers and has for its object the provision of a simple, inexpensive, quiet and practical electric device whereby ozone can be produced cheaply and a reliably for purifying, disinfect ng and deodorizlng purposes in the toilet and sanitary rooms of hotels, office buildings, railway stations, steamships, public halls, theatres, and other places.
In the drawing accompanying and forming a part of this application I have shown one physical structure in which my invention is embodied, although it will be understood that this drawing is intended to be illustrative of principles rather than exhaustive of the appliances by which the same can be utilized.
Fig. 1 is a vertical sectional view through a specimen ozonizer in place on a wall. cor responding to the line 1-1 in Fig. 2; Fig. 2
is a horizontal sectional view on the line 22 of Fig. 1; Fig. 3 is a perspective view of the ipparatus showing the parts separated; and
ig 4 is a diagram of the magnetic and electric connections.
In its preferred form the casing of my improved ozonizer consists of a rectangular sheet metal box having a back 1 adapted to be secured in vertical position to a wall, a front 2 spaced therefrom, and vertical sides 3--3, here shown as outwardly-displaced at 4-4 to define inwardly-opening recesses for a purpose hereinafter explained. The inner faces of the walls 1 and 2 are here shown as covered by insulating layers 5 of any suitable material such as waxed paper.
Located inside this casing with its edges tightly received in the recesses 4+4 is the rectangular laminated frame 6 of a transformer, said frame having two verticallyspaced horizontal portions 7 and 8. the former having a primary coil 9 wound thereon and the latter asecondary coil 10. In the present embodiment the coil 0 is made with approximately one hundred times the numher of turns as the primary 9 so as to increase the voltage from 110 volts t0 upwards of ten thousand volts. In addition to the cross members 7 and 8 of the transformer frame I have also shown a third, narrower cross member 12 for the purpose of securing a small amount of magnetic leakage at all times, regardless of the demagnetizing effect of the widing 10, and thereby inducing a more powerful magnetism in the core frame.
The coils 9 and were both spaced from the rear wall 1 of the casing and between said coils and said rear wall I interpose a narrow, flat-sided, elongated tube 13 of suitable insulating material such as mica wound in layers and suitably cemented together. The upper and lower ends of this tube or fiue are left open to enable the circulation of air and have free communication with suitable inlet apertures 14 in the bottom plate 15, and with a suitable screen-eloth-covered outlet opening 16 in the top plate 17, with which said casing is provided. Inside said tube I locate a rough surfaced sheet 18 of metal, so located relatively to the wall of the tube as to define therewith a passage-way for air. One terminal 19 of the secondary winding is connected to said sheet of metal. the wall of the tube being preferably slotted as shown as 20 to enable the ready introduction and removal of the electrode. the secondary winding is suitably grounded to the plate 1 of the casing, or other member electrically connected therewith. In the present embodiment this is effected by welding the terminal 21 to the frame 6.
The electrode 18 is preferably made of some oxidation-resisting metal such as alum num and to secure the roughness desirable I have found nothing better than a piece of woven-wire-screen-cloth of this material. Other metals like brass, copper, iron, etc, can be employed. but these ordinarily become wasted away by the operation of the device, and frequently produce an acrid and unpleasant odor, from which aluminum and The other terminal 21 of certain other of the oxidation-resisting metals are free.
Alternating current at 110 volts is supplied to the primary coil by way of the terminal wires 22. The essential electric and magnetic connections are illustrated in Figure 4. The screen cloth member 18 constitutes one electrode and the casing and its internal metal parts constitute the other electrode. Upon energizing the transformer the surface of the electrode 18 becomes bathed with a dim, purplish-colored light which is apparently of the nature of theso-called corona discharge since it is quiet and noiseless. Thermal circulation of the air through the tube 13 past this electrode causes the same to become sufficiently ozonized for the disinfecting and deodorizing purposes hereinbe'fore mentioned. The cost of the apparatus is verysmall, its consumption of currentis only nominal, the sanitary, therapeutic, germicidal, and deodorizing eflectof ozone is much superior to that of the'oils and other chemical preparations customarily employed for these purposes, and the device requires no refilling, renewal, or
attention.
It will be understood. however, that while I have described indetail the particular physical embodiment of my invention herein chosen for purposes of illustration, I do not limit myself to those details or to that physical embodiment in anywise except as specifically re cited in my several claims which I desire may be construed each independently of limitations contained in other claims.
Having/thus described my invention what I claim is:
1. An ozone machine comprising: a casing having a front wall, side walls provided with inwardly extending flanges adjacent the rear edges thereof, and also with longitudinally extending channels, and a separate rear wall secured to said flanges, said side walls having laterally extending flange portions at each end thereof: a transformer having a laminated core disposed within said casing, and having the opposite sides of said core tightly engaging said'channels to maintain the laminations thereof against displacement; and ends of openwork structure secured tosaid laterally extending flanges at opposite ends of said casing to permit of the circulation of air through said casing and around said transformer.
2. An ozone machine comprising: a sheet signature.
