head jointly on the rubber bulb and the fluid. re-

ceptacle.

Referring to the drawing: Fig. 1 is a cross section of a-complete atomizer, except as to the head, which latter is shown in elevation, embodying the invention.

Fig. .2 represents a plan view of theatomizer shown in Fig: 1.,

L Fig. 3 represents a cross section of the atomizer head along lines 3--3l of Fig. 5.

Fig. 4 represents across section of the atomizer head along lines 4 4? of Fig. 5.

Fig. 5 represents a plan view of the atomizer head shown in Figs. 3 and 4.

Fig. 6 represents a cross section of the complete neck of the rubber bulb shown in Fig. '7 along lines B -6 Fig. 7 represents a cross section of the upper part of therubber bulb, broken away from the main body of the bulb.

Again referring to the drawing, the atomizer is composed of a soft rubber bulb 2, which is provided with an open neck 2 the neck being hollow and opening into an enlarged cavity of the bulb and which bulb is closed except as to the opening 2 in the neck. The bulb has a flat surface on the bottom on which to rest. The bulb 2 is constructed to receive a fluid receptacle 5, as illustrated in Fig. 1 and tapers upwards and downwards from its middle to form the neck- 2 at its upper end with opening 2 and an an nular air channel 8, in the form of a recess on the inside of the neck, near the top of the bulb.

' nication with the annular air space 8 of the neck. A further horizontal cavity or recess 1* is arranged on the inside of the neck 2 a short distance below the annular air space 8, to receive a lip 1 of the fluid receptacle when in position, see Fig. 1.

The atomizer, in addition to the bulb, comprises a fluid receptacle 5 and an atomizerhead l which latter has a neck l for closing the'fluid receptacle and the neck 2 at the same time. The fluid receptacle is filled first and then the shown) tacle by'its neck I a being thrust into the opening of the fluid receptacle into which it 'fits snugly, a rubber gasket (not shown) being attachedto the neck I after which the fluid receptacle is inserted into the neck'2 of the bulb into the position shown in Fig. 1.

The atomizer head I, is made of screw stock suitable for the antiseptic or other fluid'to be used therein, or it may be made of a die casting. The head l'proper is arranged with air passages as illustrated in section in Fig. 3 and fluid passages as illustrated in Fig. 4.v It will be noted that the fluid passagesenter into and terminate in mixing chamber space l5 at l5 Fig. 3. These fluid passages areshown in cross section in Fig. 4 and designated as 26and 21, while'themixing chamber l5 with mixing space l5'is shown-in cross section in Fig. 4. See Fig.

5 lines l i for the direction of the fluid passages into the mixing chamber l5 of nozzle 4.

As will be noted the atomizer head has mounted on it nozzle 4 onto the outer end of which is screwed cap 3 to seal the end of the nozzle with a gasket seated on the inside of cap 3 (not The atomizer head also has mounted at'the neck end I a fluid tube 29 provided with notches 30 for attaching rubber hose 6 to reach the bottom of the fluid receptacle and in the fluid passage 21, a plug 28 is arranged to close that passage, so thatthe fluid will be elevated through rubber tube 6 into passage 3|, thence into

passages

21 and 26 into opening l5 in the mixing chamber l5 and ejected throughopening M of nozzle 4. The atomizer head further is provided in the air passage [6, at its upper and lower enlarged openings, with two check valves II and 20. These check valves are made up of casings II and which contain ball valves l2 and I8, and springs l3 and H), which are held in the casings by the flanges illustrated in the drawing. These check valves are further provided with

openings I

0 and 22 and 2| and 23 respectively on the upper and lower check valves, so as to be in open communication with air passage l6. It will also be noted that air passage [6 is in open communication with mixing cham- PATENT omceiz i ber l5 of nozzle 4 and that a passage I1 is placed while the upper check valve will permit air to enter passage II] for the inflation of the bulb, but will not permit the exit of air through passage I!) when the bulb is deflated by hand. Cap 3 of the head I is knurled as indicated at 3.

The neck opening 2 is somewhat smaller than the outside diameter of the fluid receptacle, so that when assembled the neck 2 will fit snugly around itand make a tight joint between the neck of the bulb and the neck I of the atomizer head with the enlarged part of the atomizer head resting against the top of the neck of the rubber bulb, as illustrated in the assembly of Fig. 1. It will be apparent to anyone skilled in the art, that a pressure on the soft rubber bulb will expel the air when the cap 3 is removed and mix the fluid with it in the mixing chamber l5 to atomize it and expel it in that form through passage l4 and that when the bulb is released from its deflated condition that the springiness of the bulb will suck in air through passage ID, as well as through the nozzle opening I4 and pass down through air channels I6, I 'l, thence through 8 and through 9 into the body of the bulb until it is again fully inflated with air when the operation of expelling and atomizing is repeated.

I claim: l

1. An atomizer comprising a hand operated bulb having a hollow neck formed with a longitudinal air passage leading into its interior, said neck having an annular cavity on its inner circumference communicating with said longitudinal air passage, a fluid receptacle within said bulb and having an externalperipheral lip receivable in the neck of said bulb to support the fluid receptacle, a head having air and fluid passages which communicate respectively with said annular air passage and the interior of the fluid receptacle, a spray nozzle carried by the head, said spray nozzle having communication with the air channel and the fluid receptacle.

2. An atomizer in accordance with claim 1, wherein there are check valves for controlling the air and fluid passages of the head.

3. An atomizer comprising a hand operated bulb having a hollow neck with an air passage located within the neck of said bulb leading into its interior, a fluid receptacle within said bulb, means within the neck to support the fluid receptacle, a :head directly mounted onsaid bulb, said head having air passages which communicate directly with the air passage within the neck of said bulb leading into the interior of the bulb and fluid passages which are in open communication with the fluid receptacle, and a spray nozzle carried by said head, said spray nozzle having an enlarged chamber at its inner end and within the head, into which the air and fluid passages converge to atomize the fluid and eject it from respectively with the air passage in said neck and the interior of the fluid receptacle, said head also being provided with a mixing chamber into which the air and fluid passages converge and a spray nozzle communicating with said mixing.

chamber and carried by said head.

5. An, atomizer in accordance with claim 4 wherein there are check valves for. controlling the airand fluid from the fluid receptacle into the head. I 1
