Specification of Letters Patent.

Patented May 18, 1915.

T0 czZZ whom t may concern Be it known that I, ALLEN DE VILBIss, a citizen of the United States, and a resident of Toledo, in the county of Lucas and State of Ohio, have invented a certain new and useful Atomizer or the like; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same, reference being had to the accompanying drawings, and to the characters of reference marked thereon, which form a part of this specification.

This invention relates to spraying or atomizing instruments and particularly to those of the compression type in which air is injected into a liquid receptacle to effect a discharge of liquid therefrom in spray or vapor form, but is not restricted to such use as it may be used in any connection for which it may be adapted or appropriate.

The object of my invention is the provision of an improved instrument of the character described, which is simple and inexpensive in its construction, and has the parts thereof capable of being easily and quickly removed, whereby to enhance the commercial value thereof.

A further object of the invention is the provision of an instrument of this character which has the liquid tubes thereof easily removable from the carrying head to facilitate a cleaning of the spraying parts and also to enable rubber tubes or the like to be used in place of metal tubes when the liquid being discharged has an injurious effect 0n metals, thus enlarging the scope of use, improving the sanitary conditions, and enhancing the practicability and efficiency of such instruments.

Other objects and advantages of the invention will be apparent from the following detailed description thereof.

The invention is fully described in the following specification, and while, in its broader aspect, it is capable of embodiment in numerous forms, three embodiments thereof are illustrated in the accompanying drawings, in which,

Figures 1 and 2 are similar sectional views of atomizers embodying slightly different forms of the invention. Fig. 3 is an enlarged detail of a portion of Fig. 2 with the liquid tube removed from within the air discharge tube. Fig. 4 is a side view of the liquid tube removed from the atomizer, and Fig. 5 is a sectional detail of a slightly different form of the invention with the air tube partly broken away and the liquid tube removed therefrom.

Referring to the drawings, 1 designates a liquid receptacle on the open neck of which is mounted a ferrule 2 into which the head carrying the spraying parts of the instrument is secured or otherwise suitably attached as is customary in instruments of this class.

In Fig. 1 the head which carries the spraying parts is designated 3 and has a heel-piece l to which a tube (not shown), connecting with a compression bulb or other source of fluid pressure supply, may be attached. The heel-piece 4f has its bore in communication with the interior of the receptacle 1 through a passage 5 in the head, which passage constitutes the only outlet for air pressure in its passage through the heelpiece. Projecting from the head 3 preferably at the opposite side from the heel-piece il is an air discharge tube 6, which is fitted at its outer end with a discharge nozzle 7 having a restricted discharge orifice 8 therein, and has its inner end in lateral communication through a passage 9 in the head 3 with the interior of the receptacle.

Disposed within the air tube 6, preferably in concentric relation thereto, is a small liquid-discharge tube 10, which has its outer end fitted into the bore of the nozzle 7 in a manner to permit a discharge of air through the nozzle around such tube, as by making the outer end portion of the tube 10 triangular in cross-section, as shown at 11. The inner end of the tube 10 seats within the mouth or outlet end of a passage 12 in the head 3, which passage communicates at its inner end with a tube 13, which is threaded into the plug or bottom portion of the head 3 with its bore in register with the passage 12 and has its lower end extended down to adjacent to the bottom of the receptacle, as shown. Upon a screwing home of the nozzle 7 within the air tube 6 the restricted outer end portion of the nozzle bore abuts against the outer end of the liquid tube l0 and forces the inner end thereof to a close seat within the enlarged outer end portion of the head passage 12. It is evident with this construction that the liquid While the heel-piece Whichisdesignated 4b tube 10 can be quickly removed for the purpose of cleaning or for substituting another' therefor by simply removing'the ,nozzle 7 from the tube 6 for `such purpose. Depending from the bottom or plug portion of the head 3 in spaced concentric relation to the tube 13 is a tube 14, Which'is preferably threaded at its upperrend into the head 3 and has the annular passage Which is formed between it and the tube 13 in communication with both of the air passages 5 and V9 in the head so that airpressure has its inlet to and exit from thereceptacle 1 through 'said ftube. The tube 14: extends a considerable distance down into the receptacle 1, and has for its purpose to prevent an escape ofli-quid from the receptacle through the air passages. 5 and 9 upon an inverting of 'the receptacle 1 or a laying of the same on its side.

InFi'gs. 2 4and 3 the spraying-part carrying-head is designated 3a and has .an opening 15 provided entirely therethrough in transverse relation to the receptacle. The air discharge tube 6 has its inner end fitting into and extending through the opening 15 and the heelfpiece la has its inner end projected into the rear lor inner end portion of the tube 6. Air under pressure isV introduced into the Ireceptaclevl from the bore 16 of ,the heel-piece through a channel or passage 17 in the head aL land has its eX-it from the receptacle into the inner end portion of the tube 6 in Aadvance .of the heel-piece through a passage 18. .The removable liquid discharge tube 10, which is mounted Within the airtube 6, has itsinner end lseating against the inner `end of the heelpiece la with its bore-in register- With theliqud passage 19, ywhich extendsthrough a v`portion of such heel -.piece,the Wall ofthe tube 6 and the head 3a into the interior of the receptacle 1. K4A tube 13 extendsfrom the inner end of thepassage A-19 dovvn'into the receptacley nearly to theY bottom thereof, such tube being removably threaded to -the bottom portion 'of the head 3". In this form of thevinven-tion, the heel-piecefl"t -and tube 6 are soldered, or .otherwise fiXedlyY- secured Within the opening 15 of the head. .The nozzle 7 of this form of theinvention-isgremovably attached to the'outer end of the tube 6 and vserves toremovably retainth'e In Fig. 5 is illustrated thefpreferred` manner of securing the heelepiecefand--air-discharge tube to the carrying head. In this form the head, which .is substantially the same asthat shown in Figs.V 2 and 3, is

designated 3a 'and theair-diseharge tube 6 has its inner end fitted into the'opening 15 through the head, but preferablyv terminating short of the rear end of suchV opening,

has its inn'e're'nd portion tapered to adapt it When inserted into the rear end of the opening 115.110 be forced into the inner Vor rear 'end yof the tube J6 and to have a Wedge or expanding action thereon, thus securely fixing Y'the lheel-piece and air-discharge tube ktogether Within the carrying head in rigid relation thereto. The heel-piece 4b is preferably provided With a shoulder, as at 24, for coacting With the rear end of the head 3a to limit the inward movement of the heel-piece therein.v The heelfpiece lll has its lair inlet passage 20 extended par-t Way therethrough and communicating ati-ts innerfend portionvvith the interior of the receptacle `on which the headvmay be mounted through a passage v21 and-thence from the receptacle through the 'outlet air passage @12in the Ahead to the rear` end ofthe air-tube 6, While the liquid passage from the receptacle ,through the head is-shoW-n fat and has its outlet end terminating inthe inner end por'- tion Vof the `heel-piece 4b opening into the air tube 6 axially thereof whereby to per- -mit a sea-ting of the innerend of la removable liquid tubelO therein. It is evident that any eneof the forms illustrated herein is exceedingly simple to manufacture, as after a `securing nf the heelpiece and lairdiscl1.arge tube together before a mountingof the -saine Within 'the` carrying head,vsu ch lieadis bored'toqprovide the air inlet and outletpassages and the liquid passages Within the4 hea-d and the respective parts through vvhich'they pass.

Itis also evident that -aninstfrument exnbodying my invention ni-ay have-the liquid tubes 10 1and 413 thereof of metalfor the metal tubes may bereplaeed if desired'by tubes of rubber or other `sui-table material cap able of `Withstanding the action `of viodin or other metal destroying liquids which might beusedinthe instrument, thusprolonging the life of instruments of this character and enabling one instrument Ito be usedV for different :kinds/of liquids, as desired, Without,- injurious effectthereon;
