.2 Claims.

This invention relates toatomizers and more particularly to new and useful improvements in pocket size atomizer construction.

An object'of the invention is to provide a pocket size atomizer having thefewest possible parts, including a one-piece block member having various openings drilled therein in such relationship that a plunger disposed in one: of'the openings will cause atomization of liquid contained in another of'the' openings;

Another object is to provide a pocket size atomizer that" is leak' proof; attractive in design, easy to assemble an'd'can withstand long usage without requiring servicing.

These and other objects'are accomplished in brief, by providing an atomizer that has a block member that can be made from a solid block of material by drilling thereina well, a well air vent, a hole to the well adapted 'to admit a tube, an air compression chamber and an air passageway extending from a vent above the hole to the compression chamber. A tube is disposed in the hole with a portion extending into the well and a nozzle projecting from the block to a positionedjacent the air passageway Vent. The bottom of the Well is closed b a threaded plug, and a spring impelled plunger isslidably disposed withinthe air compression. chamber and is adapted to force air through the air passageway and its vent to cause atomizationoflliquid from within the well.

For further comprehension of the invention, andof the objectsand advantages thereof, reference will behad to-the: following description and-accompanyingdrawings andto the appended claims in whichithevarious novel-features of the invention are more particularly set forth;

In the accompanying drawingsforming a-materialpart of this disclosure:

' Fig. dis a horizontal sectional view taken on the line (i-tof Fig. 4'.

Fig; '7 is a perspective "view of the top portion of the atomizer'.

In the drawings and "in the specification, in which like: reference numbers designate similar parts, a pocket atomizer-Jonas a block member ll, preferably of aluminum or other light metal, said block being-shaped? with a fiat bottom face 12 and a stepped top having a topmost face l3, a middle top face;ilandra-lowermost topfacelfi.

The block H has-acylindrical air compression chamber l6 extending-downwardly from its topmost face I -3'to a'conical-terminus ll adjacent its bottom face l2, andia cylindricalwell lilextending upwardly-fromitsbottom face l2 to a conical terminus" [9- below its stepped top faces. The mouth 20- of thewell I 8" at the bottom of the block I I is threaded, and a threadedeplug 2'! is engaged therewith to closeflth'e well at its bottom. A hole 22 extends downwardly from the lowermost top face l5 of the block tothe'well conical" terminus l9, and a tube 28 extends through the hole 22 with a reduced nozzle [A projecting upwardly from the lowermost top face l5 and a tubeportion 25 disposed within the well, the endof the tube within the well: being slightly above the threaded plug 2| so that liquid in the well can readily enter the tube: A wellair vent 26 extends downwardly from the middle 'top face [4 of the block to the well conical terminus l9.

A cylindrical passageway?! extends upwardly from the bottom face =1 ziofthe block betweenthe air compression chamber l6 and the well l8, said passagewa rising to about the sam elevation as the conical terminus of the well, and another cylindrical inclined passageway 28 extends upwardly and laterally from the upper end of the passageway Z'Itoa vent 29in a'vertical face '30 connecting the middle top face t4 andthe lowermost top face .15; The'venttll and the tube'nozzle 24 are adjacent each other, and 50 positioned as to cause atomization: of liquid within the well when air is forced outwardly through the vent. A plug 3| permanently'seals'thelower end of the passageway 21, and an aperture 32 extends'between the passageway 21* just above the plug'and the conical terminus l"! of the air compression chamber. Thus; 'a continuous air passageway is formed leading from'the compression chamber, through the aperture 32', up the vertical passageway 21, through" the inclined passageway 28 and out through thevent 29, the permanent plug 31 sealing'the bottom of 'the'passageway 2'1 and forcing the air from the? compression chamber to follow the course outlined.

The relative positioning of the well, chamber, passageways, holes,'ventszand. apertures" is of the utmost importance; since :they have beendesigned to permit the atomizer block to be made from a solid b ock of material allowing many of the drilling, boring and reaming operations to be performed simultaneously or consecutively on pieces held in a jig or fixture. Thus, with the bottom face of a block exposed, the we l and the passageway 21 can be bored and drilled and the well mouth threaded, and with the top face of the block uppermost, the air chamber, the tube hole 22, the Well air vent 26, the passagewa 28, and the aperture 32 can be bored and drilled. With the block thus formed, the tube 23 can then be force fed in the hole 22 to the position shown in the drawings and described hereinabove.

A collar 33 is disposed within the air compression chamber l5 below the topmost face I3 of the block, said colar having an air intake 34 and a concentric opening 35 therethrough. A plunger assembly 36, consisting of a plunger stem 31, a rubber gasket 38, gasket seat 38', washer 39, a spring 40 and a nut 4|, is positioned with the plunger stem 31 extending slidably through the opening 35' of the collar 33, the

gasket 3.8 threaded on the lower end of the stem between the gasket seat 38' and the washer 39,

the spring 40 located within chamber [6 between the gasket and conical terminus I1 and acting to force the plunger upwardly and the nut 4| gask t and washer securel in position. The plunger stem 31 has an enlarged end 42 which engages the colar 33 when the plunger is fully depressed, leaving a domed top portion of the end 42 ext nding somewhat above the topmost face I3 of the block.

The atomizer I!) is provided with a pivotally mounted top portion 43 (see Figs. 1 and '7) which is formed with a cover 44 having front and back parallel edges 5, a curved edge 46 extending 'between the edges 45, a flange 41 extending downwardly from the edges 45 and 46, and two cut-out portions 48 extending inwardly from its remaining edge 49 leaving a center tongue 50 therebetween.

The top portion 43 is rotatably joined to the block II by means of a pin 5! which extends through two opnosing holes 52 in the flange 41 and a hole 53 which extends transvers ly through the stepped top of the block. The stepped top of the block is set s ightly in at sides 54 so that the cover 44 is flush with the topmost face I3 and the flange 41 is flush with the front and back faces of the block, while the tongue 50 rests in a slotl55 in the to most face I3. In closed position, the undersurfaoe of the cover 44 seals the tube nozzle 24 and the well air vent 26 preventing leakage of liquid from the well.

The enlarged end 42 is provided about its o ter ripher with a groove 42 hich ton ue 50 engages while the atomizer is in inoperative position.

When it is desired to use the atomizer of the present invention, it is necessary first to release plunger 36 by pressing inwardly on end 42. This causes top portion 43 to rotate on pin 5| thus disengaging tongue 50 from groove 42' and permitting plunger 36 to spring upwardly due to the force of spring 40. Now each time the plunger is pressed downwardly the air within chamber [6 becomes compressed, is forced out through aperture 32, passageways 2! and 28 and .out through vent 29, thus producing a change in atmospheric pressure in tube 23 and resulting in the rise of liquid within the tube due to the threaded on the stem to retain the 4 aspirating action thus brought about. At the same time, the liquid so raised is formed into a fine spray by the air which escapes through vent 29.

5 If it is desired, the well air vent 26 can extend from the well to a terminus in any face of the block, and a tiny one way air valve disposed therein to permit air to enter the well.

While I have illustrated and described the preferred embodiments of my invention, it is to be understood that I do not limit myself to the precise constructions herein disclosed and the right is reversed to all changes and modifications coming within the scope of the invention as defined in the appended claims.

Having thus described my invention, what I claim as new, and desire to secure by United States Letters Patent is:
