MACHINE FOR OZONIZING AIR.

Specication of Letters Patent.

Patented Sept. 11, 191 '7.

Application led August 19, 1914. Serial No. 857,454.

To all 'whom t may concern:

-Be it known that I, ANDREW PETERSON, a citizen of the United States, and a resident of Newark, county of Essex, and State of New Jersey, have invented certain new and useful Improvements in Machines for Ozon- Vizing Air, of which the following'is a specification. y

This invention relates to a machine for ozonizing air and relates more particularly" to the arrangement of the ozonizing appa- ,Y ratus in a casing, and relates also to -the means of distributing the air that is passed through the ozonizing apparatus. As ozone is manufactured for distribution in a room noise which is unpleasant and` very oftenv makes the use of the machine prohibitive,

especially in institutions like hospitals where it has an eect on the patients by making them nervous.

In my improved form of ozonizing apparatus I provide a casing in which the ozonizing apparatus is installed, the casing having an air inlet nearthe bottom and an air outlet near the top, and it also contains apparatus for forcing the air through the casing and through the ozonizing apparatus so that the circulation of the air is not sluggish and the air is taken in at a point near the floor where it is less apt to be contaminated.

The invention is further designed to provide a casing in which partitions are placed to cause the air to pursue a circuitous passage through the casing, and the structure is further designed to prevent noise, such as slight hums or vibrations, from being heard outside of the casing, whereby the device is well adapted for use in hospitals and the like where quiet surroundings are desirable.

The invention is further designed to provide a dispensing or distributing structure chamber or room, and as the work continues by reason of the circulation of the air, the

air `will gradually work down to the level of the occupants and its strong odor is very much weakened and its presence is not unpleasant. v

The distributing structure is preferably ornamental and can be made in the form of artificial plants, Statuary, in fact any ornamental element that can be made to act as a distributing-element, the ornamental structure being preferably mounted on the casing which acts as a pedestal for it, the ornamental structure having a passage through it which is in communication with the interior of the casing and thus acts to conduct the ozonized air from the casing and provide outlets for its ejection. In the casing or plants the ozonized air can be projected from the trunk or other parts of the plant, and by being sent against and through the leaves, is further mixed with the air and is in a sense broken up so that it is not offensive in smell, due to its being concentrated and not having been thoroughly mixed with the air.

The invention is illustrated in the accompanying drawing in which I show one embodiment of the invention, although it will be understood that ornamental structures and different arrangements of parts can be made without departing from the invention.

In the drawing Figure 1 is a section of the casing, the ornamental 4structure however, which in` the form shown is an articial palm, being shown in elevation. Fig. 2 is a:

section of the casing and the lower part of the ornamental structure taken on line 2-2 in Fig. 1. Fig. 3 is a section taken in the same plane, but illustrating the top portion of the ornamental structure 1showing the outlet openings and illustrating the manner in which the ozonized air is permitted to escape from -the machine.

The invention comprises a casing 10 having sides and a back, the front 11 being usually made in the form of a door to permit access to the inside of the casing and being preferably held in place by any suitable form of lock 12. The casing has a bottom 13 and a top 14, and a horizontal partition 15 is placed -in the casing to divide it into an upper chamber and a lower chamber. In the lower chamber is mounted a suitable fnotor 1G which is driven by electric power, the connections and the wires, however, not being shown in the drawing, since any form of Wiring to bring about operative results can be applied to this invention. The motor drives a blower 17 with an inlet 18 and an outlet 1'9. At the lower part of the casing are the inlet openings 2O 'which j `by the suction of the air.

Downwardly projecting partitions 22 and upwardly projecting partitions 23 terminate short of the bottom and top of the-lower chamber, respectively, and thus cause the air to take circuitous paths on' each side of the motor and the blower, these partitions also'acting to keep out any slight noise that may be in the motor while it is running.

Mounted in the upper chamber are the ozonizers 24 which have their necks 25 projecting through thehorizontal partitions 15 so that the openV ends of the necks are adapted to receive the current of air that has come through the blower 17 and passes through the outlet 19 of said blower. The ozonizers can be of any suitable form, but I prefer to use ozonizers of a type, one form of which is shown in Patent No. 974,789. If a transformer 25 is necessary, it can be mounted above the ozonizers. The ozonizers are separated by a partition 26 which is divided to form the domes 27 and the downwardly projec'ting partitions 28 which terminate short of the partition 15. The up wardly projecting partitions 29 on each side of the ozonizers and the upwardly projecting partitions 30 outside the partitions 28 combine to cause the ozonized air, after it has passed through the ozonizer, to pursue a circuitous route for the purpose of mixing the ozone well with the air, and the ozonized air finally passes underneath the downwardly projecting partitions 31 which project downwardly from the dome 32. The air therefore passes up on the outside' of the dome 32 and is directed by the plates 33 to the outlet opening 34 in the top 14:. If desired I mayprovidea propeller or mixing wheel 35 which is freely rotatable inthe opening 34 and is rotated by the current of' ozonized air passing from the casing, andv its rotation serves to mix the air and the ozone thoroughly.

The partitions in the upper chamber which give the air, which has been ozonized,

a circuitous route toward the .outlet of the casing also serve-to prevent the escape of noise from the ozonizer if the ozonizer is of a type that causes any slight hum orbuzzing in its operation.

Above the casing is the ornamental s'tructure. which acts to distribute the ozonized air, and the ornamental structure may be of any form and consists of Statuary or articial plants, in fact any device which would be calculated to conceal its true function, the form illustrated being an articial palm. The drawing shows a counterfeit flower pot 36 which has built up therefrom an ornamental trunk or stem 37, these elements surrounding an outlet pipe 38 which is connected with the outlet 34 of the casing and continues up through the plant, acting as a support for the stem 37. The top of the outlet pipe 38 is provided with leaves' 39 which are disposed in a natural manner at the top of the trunk or stem, and between 'the 'leaves and the stems -of the leaves and also between the stems and the outer pipe 38 are outlet openings 410 which are so disposed that the ozonized air, having been mixed during its passage through the casing and also through the mixing wheel 35, is still `further mixed with the air and passes out in an upper strata of air, where the heated and contaminated air usually rises, and attacks all impurities, such as microbes and infected dus't and destroys bacilla if such are present in the air.

This gradual feeding of the ozonized air to the air in a room or compartment has an effect on the air to purify it without unpleasantly affecting the occupants of 'the room. Since the approach of the ozone to the occupants is gradual its offensive smell is not appreciable, and it furthermore is ejected into the air where it will do the most good as it comes from the machine, at the y same time being out of contact with the occupants of the room. v

The partitions in the upper and lower chambers, which partitions are shown as terminating-short of the top andbottom walls or partitions, can be extended if desired, and then perforated on the extended portion 'to provide passage for the air and for the ozonized air, instead of permitting the air to pass over the top and bottom edges thereof, as will .be understood.

Having thus described my invention, I claim:
