1933. Serial N6. 7653;452-
In Germany February 9, 1932 I V 3 Claims. (Cl. 299-89) I My invention relates to sprayers and particuis adjacent tothe bottom of container ill. The
larly to sprayers adapted to be operated by a source of air under pressure. Still more particularly, my invention relates to a sprayer adapted to be operated, for example, by the exhaust of a vacuum cleaner, which produces a large volume of air under amoderate pressure.
My invention will be understood from the following descriptionconsidered in connection with the accompanying drawing, whichiorms a part of this specification, and of which: I
r Fig. 1 is a cross-sectional view of a preferred embodiment of my invention; and.
Fig. 2 is a cross-sectional view of a somewhat modified embodiment of my invention. Referring toqthe drawing,reference character It designates a container adapted to hold liquid. Container I0 may conveniently be a 81 jar provided with a threaded top H. I A- cover member l2, provided with screw threads is adapted to. engage the threadedtop ll of jar lll. A
washergl3 of rubber or other suitable material is preferablyplaced. between the top of. the jar and the covermember g g g. Y
Secured tocovermember l2, as by welding or soldering, is an air supply tube It. One end of tube I 4 may 'beenlarged, as is shown at 15, so as to be adapted to receive the. end of an air supply conduit l6. Theother end of air supply conduit I 6 may be connected to the exhaust of a vacuum cleaner, or to anyother suitable source of air under pressure. The opposite end of air supply tube I I is constricted to, form anair blast nozzle l1 providing a relatively small airblowing opening. aperture 18 is formed .inv the side of air supply tube II which is adjacent to cover member 12. A corresponding aperture H in alignment with aperture I8 is formed in the cover member so that the two apertures together form a passage from within air supply tube ll to within jar I0.
A relief tube 20 having a smaller outer diameter than the inner diameter of air supply tube ll extends through cover member I 2 and through the air supply tube and terminates with an outer end in communication with the atmosphere. The inner end of relief tube 20 is. in
communication with the interior of container l0. There is no direct communication between the interior of air supply tube II and the interior of relief tube 20.
A liquid riser conduit 2| extends through, and is supported by, cover member l2 and the side of .air supply tube I which is adjacent to the cover member. The lower'end of conduit 2| grasping in the hand both the air supply con- .duit l6 and the air supply tube H in the region where the two are joined. In order to cause upper end of conduit 2| extends axiallywithin air. supplyconduit llj and terminates in a liquid nozzle 22 adjacent toair blast nozzle I1. Liquid nozzle 22 maybe removable from conduit 2| and 5 replaceable by other nozzles of different design for spraying different kinds of liquid. The above described embodimentoperates follows:
,In' order to fill container I0 with liquid to be sprayed; cover i2 is unscrewed therefrom. Liquid' may then be poured 'intocontain'er 10 to any desired height above the bottom of riser conduit 2|. The cover 12 is then replaced and air supply conduit'16 connected to air supply tube l4. When an under pressure is supplied through conduit i6 to'tub'e l4. it causes an increase in pressure 'above atmospherioi within tube I4, particularly L view of the constricted air blast nozzle l1. Apertures l8 and I9 permit this pressure to'be communicated to within jar l0. However, if relief tube is'open'to the atmosphere, pressure cannot'be built up in container I 0 due to the fact that the diameter of relief'tube 20'is greater than'the diameter of apertures l8 and l9. Under theseconditions, air y will be disch'arged through air blast nozzle l1, but no liquid will be discharged through liquid nozzle 22. The sprayer is conveniently heldby liquid to be discharged, the operator places a thumb or finger of the hand holding the sprayer i over the outer end of" relief tube 20. With the relief of pressure through tube prevented,
pressureisjbuilt up within container I 0 above the liquid therein and forces the liquid to rise through conduit 2i and to be discharged through nozzle 22. The bore of nozzle 22 is small and 40 the fine stream of liquid discharged therethrough is caught up by the surrounding air blast and broken up into a fine spray which is carried along by the air.
In order to stop the spraying action, it is only 4 necessary to remove the thumb or finger from the end of relief tube 20, whereupon pressure within container I0 is relieved and no liquid is forced upwardly through conduit 2| to the nozzle 22. g In Fig. 2 there is shown a modification of the above described sprayer. In this modification the relief tube 20 does not extend through air supply tube H, but is located to. one side thereof.
The length of "relief tube 20 is preferably sub- V 2 v stantially the same as the diameter of air supply tube It in order that the upper end of the relief tube shall be approximately on a level with the top of the air supply tube so that a finger or thumb of the same handwhich is used to grasp the sprayer may be placed conveniently over the open end of the relief tube. Otherwise than this, the construction of the two modifications is the same. The operation of the modification shown in Fig. 2 is the same as that of the device shown in Fig. 1, whereby it is not necessary to repeat the description, thereof.
While I have shown two more or less specific embodiments of my invention, it is to-be understood that they are for purposes of illustration only and that I am not to be limited except by the scope of the appended claims viewed in the light of the prior art. I
