Such air willi also be directed downwardly through. a; passage 20' in the :head2 portion to the topot-`v the liquid; in the container-so' as to prox/idea pres1- sure.- thereupony to assist` the atomizing action.`

Aals'o there isf a passageway 2i( which enteritis upwardlyfthroug-i the head'portion Il; To-tfie head portionv and in communication witliv thein'e'cteda screw porti'orr`24 of a screw neadf 25pm screwing action on an internally threaded* por-*- tion 25 of' the' pipe 2t:l With the. screw head" 26 inthepositionshown. in Fig. 5 the surfacesof the screw head will engage with a surface 21 on the bottom end of the pipe and tend to close the same so as to prevent fluid from entering the pipe. This has an advantage as when it is desired to ship the container with the liquid in it.

When the atomizer is to be set up for operation the screw thread 26 is turned downwardly to a position shown in Fig. 6. Liquid will enter between the threads and move upwardly into the pipe 23. The-adjustingscrew 26 has4 an extension 28 which extendsup'wardly into the top end of the pipe 23. This extension 2B is of less diameter than the interior diameter of the pipe so as to permit the free passage of liquids upwardly through the pipe. The extension 2li is of square section as shown more clearly in Fig. 4. It `will be apparent that while it is not necessary that the hole which extends through the pipe be so large in order to get a supply of liquid to the top of the same and into the head portion, that there has been provided a structure .whereby the small holel for the passage of liquid can be provided without the necessity of a delicatedrilling or machining operation. It would lbe difficult to have such a hole of such small size in a pipe which extends down to the bottom of the container and if such an arrangement were `provided it would be diilicult to effect a cleaning operation of the same. With the present structure the pipe v23 can be removed from the head portion I4 and the ex tension 28 taken out thereof and the pipe readily cleaned. At the same time the passage of liquid through the same is limited and there is little opportunity for a great amount or air to be within the liquid which is raised to the head portion I4 as would be the case if a larger opening were extended upwardly from the bottom of the container.

Itwill be noted that the threaded portion 24 has a flat portion 25A which will permit a larger ilow of liquid into the end of the pipe 23 should the screw portion 24 be withdrawn to a greater distance from the bottom end of the pipe than as shown in Fig. 6. Accordingly there has been provided an adjusting screw for controlling the amount of liquid to enter and be raised in the pipe.

In order that the atomizer may be totally closed forthe purpose of shipment with liquid therein, there is provided at the bottom end of the passage 20 screw threads 3i into which a screw can be inserted along with a sealing washer.

vFixed to the cap I3 is a laterally and down wardly inclined portion 29 which serves as a support for the bulb I8 ,and which can be grasped by the same hand that grasps the bulb so that the container with the liquid can be raised by the same hand that grasps the bulb. vAccordingly one hand can be used for dispensing the atomized fluid. Ihe'bulb I8 is simply pressed against the laterally extending portion or shelf 29. This portion 2d is curved on its top face to nicely receive the bulb I8 and to prevent the bulb from being laterally olset from the same. v

The `bulb I8 will have two valves therein so that it acts as a pump. When this bulb is taken with the laterally extending portion` or shelf `2S there is provided a handle for the atomizer. In other words the pump is formed in the handle. Instead of a bulb type of` pump, a piston Ior plunger type or an electric pump can be usedand.these later` pumps can also be incorporated r'in the,

handle.V y l While various changes may be made in the detailed construction, it vshall be understood that suchchanges shall be within the spirit and scope Cil '4 of the present invention as defined by the appended claims.

I claim:

l. An atomizer comprising a container having an opening portion thereon, a closure element adapted to be removably connected to the opening portion of the container, said closure element having a head portion with an air passage extending Atransversely therethrough and two vertically extending passagesv extending `from the lower end of the head portionand communicating with the transversely extending air passage, means for forcing air through the transverse air passage, one of said vertically extending air passages serving to supply air pressure to the top of liquid within the container and the other of said vertically extending passages serving to communicate liquid to the transverse passage to atomize and dispense the same, a separable pipe connected to the head portion in communication with the vertically extendingv passage which receives the liquid, an adjustable and removable liquid control element engageable with thebottom of the pipe, and means extending from the control element upwardly into the top of the pipe and into the head portion of the closure element to provide capillary space within the pipe and head portion for the flow of liquid, whereby the amount of liquid entering the pipe can be controlled and whereby the liquid passage oi' the atomizer can be cleaned by the removal of the adjustable control element from the pipe and the pipe from the vclosure element. A

2. An atomizer comprising a container having an opening portion, a closure element adapted to be removably connected to the opening portion of the container, said closure element having a head portion with a horizontally extending air passage therein, means for supplying air under pressure to the air passage, said head portion further lhaving two vertically extending passages communicating with the horizontally extending air passage, one of said vertically extending 'pas-j sages serving to supply air under pressure to the" top of the liquid contained within the container, a pipe connected to the headportion in conrmunication with the other vertically extending passage and extending downwardly to then bottom of the container, an adjustable and ,removable liquid control element adjustably connected to the bottom of the pipe ,and `extending upwardly thereinto to limit the flow of liquidpassing through the 'bottom end of' the-pipe,-an extension on the control element having azflat face and extending upwardly through the 'pipe'='finto the upper end thereof and'intothe head portion of the closure elementjsaid flat face/of lthe extension providing for a capillary passage throughout the length of the pipe'betwe'en the extension and the interior wall face'of the'pipe, the lower end of the pipe having v`a threaded interior and the adjustable control elementb'eing" threaded to engage therewith` whereby, the amount of liquid entering the pipe can be Acontrolled and upon the control element and'its' extension being cleaned. V ,I

3. An atomizer as dened in claim 2, and ysaidv control elementhaving a] tapered face thereon, thelower end of the pipe. having a countersunk removed, the pipe can be readily face adapted to vbe'engaged by the, taperedfacel of the control element to permit the engagement therewith of the tapered face, whereby toshut oir the flow of liquid upwardly through the' pipe at times when the container is being shipped Number Name Date with the liquid. 1,229,771 Mattern June 12, 1917 BARNETT BARON. 1,859,273 OCOnnOI May 17, 1932 1,866,909 Schlpf July 12, 1932 REFERENCES CITED 5 1,867,890 Pyn July 19, 1932 The following references are of record in the 1935973 Altmann NOV' 21 1933 me of patent: Hunter June 22, 2,362,784 Ward NOV. 14, 1944 UNITED STATES PATENTS FOREIGN PATENTS Number Name Date 10 218,164 Corey Aug. 5, 1879 Number Country Date 281,942 Sutton July 24, 1883 183,108 Great Britain Apr. 30, 1923 460,458 Bates Sept. 29, 1891 323,139 France Feb. 26, 1903 591,745 Du Brul Oct. 12, 1897 384,968 Great Britain Deo. 15, 1932 '712,214 Tatum Oct. 28, 1902 15 618,993 France Mar. 24, 1927
