" This invention relates to a deviceV fornebulizing liquids such medicinal liquids for The atomizersnowin use4k are usually irregular in outline, "and relativelybulky, so that they are' inconvenientto carryabout.
Likewise, vthe nebulizing nozzle orsiphon and air vent are sc "constructedthatv they are vdiliic'ult tov`seal,"and consequentl'yfthe atomizer'must be carried in some particular position to prevent'the liquid Vfrom escaping f and soiling the clothing. LAgain, difficulty `is encounteredV in roviding a satisfactory seal about the j oint- 4etween the liquid' receptacle and the 'head which carries theatomizer noz-- zle and air connection. y.
Therefore, it is an'objectof my invention to eliminate these inconveniences and defects, and to provide a very efficient nebulizer which is compact and regular in outline, so that it may be conveniently carried about. i
Another object is to provide a collapsible *is compressed. 1 Withinftheifeceptacle'1 is an scoped within the bulb for protection from breakage, Aand for additional compactness Another object of my invention is to pre- 'l vent the escape of liquid in the nebulizer byV atomizer, the parts of which may be teleelciently sealing the liquid in the nebulizer, and to exclude foreign material Vfrom the various parts of the nebulizer and to disinfect them when not in use.
A convenient form of my nebulizer is illustrated in the accompanying drawing,
vention and their relative positions when in operation, and Fig?. is an elevation illus! trating the same parts Vand their relative positions when telescoped.
The embodiment of my invention illus-V` trated-,in the drawing includes a liquid receptacle l telescopically mounted in abulb 2,*
The'
"ization is' limited onlyby the dischargeopen-k of rubber or other resilient material. bulb 2 is provided with an air intake 3, preferably located at' one end, and an intake valve 4, which operates to prevent escape of air* through the intake 3, as the `bulb is compressed, and to permit entrance of air as the bulb resumes its normal expanded position.

The receptacl'eil isoflthe' samecr'oss sectional shape as theanriular neck @preferably-cin cular..V The receptacle-shownis in the formV of a cylinder having an outerdiametfrfsl ight` `ly larger than thefinnerdiameter ofthe ari-jy nular neck j5, so thatfwhen inserted in the i bulb it isgripped tightly byj'the annularlneck` Toward one end offth'e receptacle itfis en? llarged. to forniachamber, the outer surface Lofwhich is shapedAsothat' it is substantially complementary to" the inner' 'surface-y -of the forcedout from the bulb as the-"bulb isjjcomu pressed for compressing thev air therein and -Vin actfornis a largersealingf area betweenV the bulbfandreceptacle and draws'the'fbulb tightly (about-the receptacle., whenl the bulb air tube 8l preferablyintegralv and V.axially air tube- 8 vcommuniCates k:with thebulb 2' through *a suitable opening'Qyshown in the that its discharge kend 12 projects over 'and slightly." above the 'mouth ofl the f nozzle *10.
The Siphon tube may be' supported by'thev lwalls of the "receptacle, 'l or by-'securing it to y theair tube 8, as shown.l @The Siphon tube 171 extends preferably parallel to the airtube8 and has ,its intake near the'bottom of the chamber 7 and immersed in` the liquid to -atomized.jf* p The portionofth'e receptacle that maybe. Y filled withliquid andyet-merit'suicient atoming of the'nozzle"l0,`"whch for operation* must "project out of the'lquid.L AThe pressure of air forced into the air tube by compressing the bulb isltransformed -intoea velocity bythe nozzlelOQcausing a relatively `low pressure y les vat the discharge endof the siphon tube. This Y nebulus which is driven out of the receptacle Y results in drawing the liquid up through the siphon tube l1 and discharging it into theV relatively high velocity air stream from the nozzle 10. -I-Iere it is minutely broken up 1 and mixed withtheair, forming a mist o r by the air stream. The receptacle 1 is formed near its discharge end with a Yneck-portion 13 having an annular'shoulde'r 14. YThe length of the receptacle measured from its shoulder to its farthest end is such that when the resV ceptacle is telescoped into the bulb 2, as illus-. trated in-Fig. 2, the annular shoulder rests -u-pon theupper surface Vofthe annular neck 5. The frarend of the receptacle is a short distance from the valve end ofthe bulb 2.
. It is; desirable to; form the. inner surfaceof -i ,the lowerend ofthe bulb substantially lcomplementary toi'the adjacent portion of the outer surface ofthe walls of thel chamber 7 "so thatthe receptacle will be supported at v`both ends when'- telescoped and out lof use.
Theouter surface ofthe neck portion of the .receptaclebeneath the shoulder 14 is tapered orl sloped inwardlyV yof Ythe. receptacle so .that
when the receptacle isrteleseoped in the fbulb Ithe Yannular neck 5 ofthe bulb grips about .theftaperedpcrto of theV neck 1.3 adjacent Vto' the shoulder 111 ofthe receptacle and the y YYY.Sllblllderflllengages the endof the-neck V5 of Lthebulb.
