ATOMIZER Filed July 27, 1944 INVENTOR M/u L. 00L DEE/PT ATTORNEYS Patented Oct. 2, 1945 UNITED STATE-S PATENT OFFICE ATOMIZER Max L. Goldbert, New York, N. Y. Application July 27,1944, Serial No. 546,767 8 Claims. (01. tea-8s) My invention relates generally to atomizers, and in particular it relates to atomizers which provide means for varying the character of the spray. The main object of my invention is the provision of an atomizer which disseminates fluid material'in various degrees of diffusion.

A further object of my invention is the provision of an atomizer in which a plurality of tubes are provided extending from the fluid material to be dispensed to the atmosphere, and a spray head is provided which is shiftable into cooperative relation with any one of the tubes, as desired.

Still another object of my invention is the provision of an atomizer having a plurality of tubes of different diameter, and a spray head which ma be selectively associated with one or the other of the tubes, whereby the character of the spray may be varied.

Other and further objects of my invention will be specifically pointed out in connection with the following description of an illustrative embodi- A ment, and still others will be apparent therefrom.

3-3 of Fig. 1; and

Fig. 4 is a horizontal section on the line 44 of Fig. 2.

My device, indicated generally by reference numeral Ill, comprises a housing l2 formed as by molding, casting or other process, of any suitable metallic, plastic or other material. Housing i2 has a pair of longitudinally extending chambers l4, I5 therein; the smaller chamber l4 opening upwardly towards the top of the housing, the larger chamber opening downwardly towards the bottom of the housing. An air passageway 30 is formed through the body of housing l2, between the chambers l4, l5, leading from the bottom of chamber H to the atmosphere, venting through the top of housing I2 above chamber l5.

Chamber l4, circular in cross-section, comprises the pump chamber. I dispose therein a relatively elongated piston rod it, having a circular washer l8, of rubber, leather or-other suitable material,

at the bottom thereof sealing against the sides of the pump chamber. The mouth of chamber I4 is internally threaded, as indicated at 20, and there is screwed or otherwise fixed therein a plug 22, through a central aperture in which piston rod I6 projects. A cap or button 26 is fixed to the top of piston rod I6, and is provided with an annular notch or groove 25 which cooperates with a finger piece 24 extending upwardly from plug 22 into the recess 24. A vertical slot 21 is formed in cap 26 below notch 25, and upon rotation of the cap to bring finger piece 24 into line with slot 21, the shaft or plunger may be permitted to rise upwardly and out of the chamber. A coil spring 28 is disposed on the floor of chamber [4, bearing against the underside of washer l8 and tending normally to urge washer I8 and shaft l6 upwardly. A plurality of air inlet openings 24, 24 are also provided through plug 22.

In Fig. 2, piston rod 16 is shown locked within pump chamber I4, for convenience in carrying the device. When cap 26 is released from finger 24, the piston is spring-28-urged upwardly, and pressure exerted downwardly against cap 26 forces a blast of air through passageway 30 and out of the housing through the spray head.

Housing l2, at the top thereof above chamber I5, is recessed to receive therewithin a spray head 32, which is locked onto the housing by means of a headed bolt 34 bearing against the underside of the housing wall. Head 32 is apertured, as at 36 and is provided with an air jet 38- at the top thereof having an offsetnozzle 40. Head 32 may be pivoted about bolt 34, a handle 42 being secured to the head for that purpose, for reasons which will be developed below.

A fluid container, as 50, maybe insertedwithin chamber IS, the open mouth 52 thereof bearing against a washer 54 secured to the underside of the housing wall by bolt 34. A leaf spring 56, pivotally secured to floor 58 of pump chamber I4 by rivet 60, urges container 50 against the washer seal 54. The bottom of housing l2 may be enclosed by a cap 62 force fitted onto reduced neck portion 64 of the housing, so that a smooth surface is presented. When the fluid material M in container 50 is exhausted, cap 62 may be removed, spring 56 pivoted away from the underside of the container, and the container removed. refilled and reinserted, or a new full container inserted.

A pair of tubes 10, 12 are provided, of diflerent internal diameters, tube 10 being of very small diameter, and tube 12 of much greater diameter. Both tubes are of equal length, and extend ,as desired, by actuation of lever arm 42.

through the top of housing I2 towards the bot tom of container ill, housing i2 and washer at being suitably aperatured to permit the tubes to extend therethrough. The tops of tubes it, 72 are level with the end of Jet nozzle 50, and head 32 may be pivoted to bring jet nozzle 48 into close proximity with the ends of either of the tubes, Stops 14, 16 are provided atop housing ii to limit the movement of nozzle 42 and properly locate Jet nozzle 40 with respect to the mouths of tubes 10,12.

When it is desired to disseminate fluid M in a very fine spray, Jet nozzle 40 is associated with the fine tube 10, but when it is desired to disseminate the fluid material in coarser, droplet form, handle 42 is swung into the dotted line position (Fig. 1) and nozzle 40 brought into proximiity to the wider tube 12.

My device is small, neat and compact, and its choice of sprays renders it extremely useful in connection with medicating the nasal or oral areas. The main feature thereof is its choice of sprays, and the ease with which, 'in the one device, the character 01 the spray may be varied.

Having now described my invention, what I claim and desire to. secure by Letters Patent is:

1. In an atomizer, a pump chamber, an air outlet, a communication between the pump chamber and the outlet, a fluid reservoir and a plurality of tubes projecting thereinto from the atmosphere, and means to associate the air outlet with any of the tubes.

2. An atomizer, as in claim 1, in which the tubes are of diflerent diameters, and the character of the spray is varied in accordance with the tube associated with the air outlet.

3. In an atomizer, a pump chamber, an air outlet, a communication between the pump chamber and the outlet, a fluid reservoir and a plurality of spaced-apart tubes projecting there- 7 into from the atmosphere, and means to move the air outlet into association with any of the tubes.

4. An atomizer, as in claim 3, in which the tubes are of different diameters, and the character oi the spray is varied in accordance with the tube associated with the air outlet.

5. In an atomizer, a pump chamber, an air outlet therefrom, comprising a nozzle, an air passageway between the pump chamber and the nozzle, 2. fluid reservoir and a plurality of.spaced apart tubes projecting thereinto from the atmosphere, means to shift the nozzle to selectively associate the said nozzle with any of the tubes.

6. In an atomizer, a housing, a pump chamber therewithin, an air nozzle on the. housing, a communication between the pump chamber and the air nozzle, a fluid reservoir within the housing, a plurality of tubes extending into the fluid reservoir and upwardly of the housing, and means to associate the air nozzle with any of the tubes.

'7. An atomizer as in claim 6, in which the nozzle is mounted on the associating means which is located midway between the tubes and which is rotatable.

8. In an atomizer, a housing, a pump chamber 7 therewithin, an air passageway through the housing, an air exit port, said port comprising an angled terminal nozzle, a fluid reservoir, a plurality of tubes from the reservoir to the atmosphere, the ends of which tubes are at substantial-' ly the same level as the nozzle, certain of the tubes being of greater diameter than others thereof, and means to rotate the nozzle to alter the direction of the air blast from the pump chamber, through the air passageway and out at the nozzle end and thereby to bring the air nozzle into cooperative relation to any of the tubes.
