ATOMIZER.

Specification of Letters Patent.

Patented Jan. 6, 1914.

Application filed November 21, 1912. Serial No. 732,645.

To all whom it may concern:

Be it known that I, CARL FELLERER, subject of the German Emperor, residing at F reising, Germany, have invented certain new and useful Improvements in Atomizers, of which the following is a specification.

My invention relates generally to atomizers, and has especial reference to that type of devices which are designed to atomize medicinal fluids, which in the form of vapors are used for inhalation or similar purposes.

The primary object of my invention is to provide means, in a device of this character. whereby the degree of moisture contained in the vapor which issues from the device may be easily regulated.

The invention is susceptible of embodiment in numerous forms, and for the purpose of illustratively exemplifying two of the forms which I consider best for the purpose, I have attached hereto a sheet of drawing, wherein- Figure 1 1s a vertical sectional view of one form of the invention; and Fig. 2 is a similar view of a second form thereof.

Referring to the drawing, the numeral 2 designates the liquid receiving tube which is in operative communication with a sub stantially globular glass receptacle 1 which forms the vaporizing chamber.

Supported within the liquid receiving tube 2 is the atomizing tube 5 projecting upwardly into the vaporizing chamber 1 through the atomizer nozzle 4:. Suitable means, such as a rubber bulb 3, is provided to furnish compressed air by means of which the liquid in the tube 2 is forced upwardly through the atomizing tube 5 and against the inner wall of the vaporizing chamber 1 whereby the spray issuing through the tube 5 is vaporized by its impact against the wall.

The parts so far described are those usually employed in the ordinary construction of atomizers.

As stated above, my invention deals with the means for regulating the quantity of moisture contained in the issuing vapor and the simplest form of the invention is shown in Fig. 1, wherein the device is provided with two emission openings or tubes 6 and 7, arranged in the vaporizer 1 at a suitable angle to each other. When it is desired to have the issuing vapor fairly highly charged with moisture, a plug, such as a cork 8, is inserted in the opening 6 leaving the opening 7 free. When the bulb 3 is compressed the liquid in the tube 2 is forced upwardly through the atomizing tube 5, and impinges against the wall of the vaporizing chamber 1, whereby the atomized liquid, then in the form of spray, is transformed into vapor containing a certain quantity of moisture. If, now, the opening 7 is unobstructed, the direction in which the spray radiates from the wall of vaporizing chamber 1 will substantially coincide with the direction taken by the air contained in the chamber 1 as it passes out through the port 7, and the spray will be given practically no opportunity to lose its moisture before it rushes out with the air. If it is desired that the issuing vapor contain less moisture, then the port 7 is closed by means of the plug 8 and the opening 6 remains unobstructed. In view of the fact that the point at which the spray issuing from the tube 5 strikes against the wall of the vaporizing chamber 1 is removed a substantial distance from the eXit port, 6, the spray will have an opportunity to lose a greater or less part of its moisture content by precipitation, and the vapor which issues from the tube 6 will be fairly dry. The precipitated moisture will accumulate in the lower part, 1 of the globe 1, and will flow through the duct 9 back into the liquid receiving tube 2, the duct 9 preferably being provided with a valve 9 as shown.

In the modified form of Fig. 2, but one emission opening 7 is shown, and I effect the regulation of the moisture content of the issuing vapor through the medium of a shutter or baffle 10 rigidly carried by a stud 11 revoluble in the wall of the vaporizing chamber 1, said stud 11 having a button or knob 12 at its outer end by means of which the shutter 10 may be suitably manipulated. In the modified form of the invention the shutter 10 may be moved into the path of the spray which impinges against the wall of the chamber 1 and when so moved will, in a sense, act as a deflector or baflie for the moist spray, whereby the vapor which issues through the tube 7 will be fairly dry. When the shutter 10 is moved out of range of the spray and the tube 7 is unobstructed by the shutter, the vapor which issued through tube 7 will contain a fairly large amount of moisture. In other respects the construction of the modified form of the invention is similar to that shown in the preferred form.

It will be obvious to those skilled in the art that the structural details of the invention may be substantially modified without departing from the scope of the claims hereto appended.

Having described my invention what 1 claim is 1. An atomizer, embodying therein a liquid receiving receptacle, a. vaporizing chamber distinct from and superimposed on said liquid receiving receptacle, means whereby liquid is conducted from the receptacle into the vaporizing chamber, means for directing a volume of compressed air against the upper liquid level in said receptacle to force the liquid therefrom into the vaporizing chamber, and means carried by the vaporizing chamber whereby the degree of moisture contained in the vapor issuing from said chamber may be regulated.

2. An atomizer, embodying therein a substantially cylindrical liquid receiving receptacle, a globular vaporizing chamber distinct from and superimposed on said liquid receiving receptacle, means whereby liquid in atomized form is conducted from the receptacle into the vaporizing chamber means opening into the receptacle near the upper end thereof for directing a volume of compressed air against the upper level of the liquid in said receptacle to force said liquid in atomized form into the vaporizing chamber, and means carried by the vaporizing chamber whereby the degree of moisture contained in the vapor issuing from said chamber may be regulated.

3. An atomizer, embodying therein a substantially cylindrical liquid receiving receptacle, a substantially globular vaporizing chamber distinct from and superimposed on said liquid receiving receptacle, a tube open at bot-h ends extending substantially the length of said liquid receiving receptacle and opening into the base of said vaporizing chamber, means for directing a volume of compressed air against the upper liquid level in, said liquid receiving receptacle to force liquid in atomized form from said tube into said vaporizing chamber, and means carried by the vaporizing chamber whereby the degree of moisture contained in the vapor issuing from said chamber may be regulated.

4. An atomizer, embodying therein a liquid receiving chamber, a vaporizing chamber in operative communication therewith, a plurality of emission tubes carried by said vaporizing chamber, means for forcing atomized liquid from said liquid receiving chamber into said vaporizing chamber, and means for directing the issue of vapor through any of said emission tubes, whereby the degree of moisture contained in the issuing vapor is regulated.

5. An atomizer, embodying therein a liquid receiving chamber, a vaporizing chamber in operative communication therewith, emission openings in said vaporizing chamber arranged at an angle to each other, means for forcing atomized liquid from the liquid receiving chamber into the vaporizing chamber, and means for closing either of said emission ports to regulate the quantity of moisture contained in the vapor issuing from the device.

In testimony whereof I have affixed my signature in presence of two witnesses.

CARL FELLERER.
