Patented .lune 13, 1933 PAT LOUIS V. ARONSON, OF NEVJARK, JERSEY, ASSIGNOR TO ART METAL W'ORKS, INC., A CORPORATION OF NEW JERSEY ALTOMIZER Application led January 25, 1930. Serial No. 423,509.

My invention relates to atomizers of a readily portable and simple character.

My invention relates to an atomizer adapted i particularly for medicinal uses, the arrange- .ment of parts being such that the atomizer is highly efficient and satisfactory in operation.

Further advantages, characteristics and objects of my invention will become apparent from the following description taken in connection with the accompanying drawing.

My invention resides in the atomizer, the device, and in the features and details of construction of the character hereinafter described and claimed.

For an illustration of one of the many forms of my invention, reference is to be had to the accompanying drawing, in which Figure l is a perspective view of an atomizer constructed in accordance with my invention.

Fig. 2' is a vertical sectional view of the atomizer of Fig. l and is taken substantially on the line 2--2 of Fig. l looking in the direction of the arrows.

Fig. 3 is a vertical sectional view of the atomizer shown in Fig. l and is taken substantially on the line 3-3 of Fig. 2 looking in the direction of the arrows.

Fig. 4 is an enlarged, vertical sectional view of the atomizing conduits.

Fig. 5 is a perspective view of latching mechanism for the pump plunger.

Fig. 6 is a perspective view of a modified closure device.

Referring to the drawing, C represents a casing or container of any suitable configura-- tion and herein shown as comprising a base l adapted to rest upon any suitable support or surface. Upstanding from the base l is the casing side wall structure 2 which may be and preferably is generally circular in hori- Zontal cross-sectional configuration and shaped to form an upper throat section 3 merging uniformly toward the longitudinal axis of said casing C. Carried by said throat section 3 is a bushing-like member 4 having a passage into which is threaded the stem 5a of a tube 5, the upper end of which,

preferably, is tapered exteriorly as indicated at 5b, Figs. l, 2 and 8.

Disposed interiorly of the casing C is a pump casing 6 sealed from the hereinafter described liquid medium in the casing C and 5scircular in vertical cross-section, Figs. 2 and 3. The pump casing 6 may be flanged at one end, as at 6a, and such fianged section may be welded or otherwise suitably secured to the interior surface of the casing C, the side wall structure 2 of which is cut away to form an aperture or opening in alinement with said pump casing 6. Threaded into an interiorly threaded section of the pump casing 6 and closing said aperture is a plug 7 c5 apertured to freely receive a reciprocatory pump plunger terminating, at one end, in a suitable knob 8a. At its other end, the plunger 8 may have a threaded shank 8b receiving a first washer 9, a sheet l() of leather, Zu suitable rubberized fabric or the like adapted to take a flanged configuration as shown, and a second washer 1l. A nut 12 threaded to the stem 8b serves to retain the parts last described in assembled relation.

The plug 7, washers 9 and ll, and the sheet 10 may have apertures disposed in alinement as illustrated for passing air to the interior of the pump casing 6. A suitable readily oscillatable member 13 may be disposed over the outlet of the aforesaid apertures and retained in position by the nut l2. The mem ber 13 functions as a flap valve to admit air to the interior of pump casing 6 through the aforesaid apertures when the plunger 8 moves in one direction and to prevent passage of air through said apertures from said pump casing when the plunger 8 moves in reverse direction.

The pump plunger 8 is biased toward and into the position shown in Fig. 2 in any suitable manner. To this end and as illustrated, a helical spring le is disposed interiorly of the pump casing, one end thereof being seated about a knob 'l5 formed on the interior sur- 95 face of the pump casing 6 and the other end thereof being seated about the nut l2.

In the example shown, the pump plunger 8 is releasably latched in its inner position, this position being the one where the spring 14 is under maximum compression, by providing on said pump plunger a latch member 16 which is coactable with a headed pin 17 projecting from the aforesaid cap 7 if desired.

Disposed within the casing C is any suitable liquid medium L which may be introduced thereinto in any suitable manner, for example, through an opening in the casing side wall structure which is normally closed by a plug 1.8 threaded thereinto, said plug 18 preferably having an exterior section 18a adapted to be manually grasped and manipulated.

Dipping into the liquid medium L is a liquid-passing tube or conduit 19 which, adjacent its lower end, is curved around the pump casing 6 and which extends upwardly through the tube 5 and terminates somewhat below the upper surface ofthe latter in a laterally directed tip or nozzle 19a. A second tube or conduit 2O is disposed interior-ly of the casing C, this conduit opening into the pump casing 6 adjacent the end thereof removed from the plug 7, being curved so as to pass upwardly through the aforesaid tube 5 and terminating in a tip or nozzle 20a disposed below and placed just to the side of the aforesaid nozzle 19a.

The tube 5 is adapted to be closed in any suitable manner and this may be accomplished in a variety of ways. Thus, in Figs. 1, 2 and 3, a cap 21 is shown as adapted for disposal or disposed about said tube 5, said cap 21 seating on the member 4. Vhere a cap is thus utilized, it may be non-detachab'ly secured to the casing C by a flexible member 22. Or, as shown in F ig. 6, the upper end of the tube 5 may be threaded, preferably interiorly, for the reception of a threaded plug 23. Or, if desired, any other suitable arrangement may be utilized for the purpose last described.

When the device is not in use, the pump plunger 8 should be in its inner position with the latch member 16 behind the head of pin 17.

To place the device in operation, the cap or closure member for the tube 5 is removed and then the knob 8a is rotated slightly to disengage the latch member 16 from pin 17. After so doing, the casing C may be held in one hand and the pump plunger reciprocated by thumb or linger action thereby pumping air through the conduit 20. The air passing outwardly through the nozzle 20ct at relatively high velocity sweeps past the nozzle 19a of conduit 19 thereby causing rise of some of the liquid medium L through said conduit 19 and atomization thereof beyond the end of nozzle 19a, the atomized mixture passing, at relatively high velocity, through and from the upper end of tube 5.

After completion of the desired atomizing action, the pump plunger 8 may be latched in its inner position in an obvious manner. This should be done before the cap 21, plug 23, or equivalent, is placed in position to minimize or obviate danger of leal*- age at the upper end of tube 5.

The device herein disclosed is intended, ordinarily, for medical uses and hence the liquid medium L usually is a disinfectant, medicinal or ysome soothing agent. The tapered end 5b of tube 5 is provided so that the tube 5 may be readily inserted in a nostril, as desired.

While the invention has been described with respect to a certain particular preferred example which gives satisfactory results, it will be understood by those skilled in the art after understanding the invention, that various changes and modifications may be made without departing from the spirit and u scope of the invention and it is intended therefore in the appended claims to cover all such changes and modifications.
