Astshown in Fig; 1, the dogs. l2 have advancedthe can tofialpositiondirectly; over the atomizing device l4; Inthis-position, the forward end of lever 24 is swung downwardly to a horizontal position and the valve platell is, dropped tothe position shown in Fig. lnwhere it movement of the compressed air. pressed air moves upwardly acro-ssthe nozzle or port 2|, creating a vacuum therein and thus', drawing liquid from At the-same time, the air atomizes the liquid and the reservoir to this surface.
causes it to move upwardly through the opening :28 and, in the form of a mist, into the interior or othersurfaces of the can or container. When the can is then advanced to the next positionthe lever 23 is released and the forward end portion thereof swings to the position indicated in dotted lines in Fig. 1. In this position,
the valve plate for; preventing; the. airflow from: the discharge orifices 1 7|; passing. The valve directly over the discharge;
21 moves upwardly across and to the rear of the air discharge opening l1. The plate thus prevents the escape of air past the nOZZle 2|, and any air that passes out of the orifice is deflected to the rear of the plate 27. Thus, no liquid is atomized or drawn forward to the nozzle 2|.
In the operation described, it will be noted that the atomizer operated only when there is a can directly thereabove. When the can is advanced by the next stroke, the atomization at once ceases, and no further discharge of liquid occurs until a succeeding can has been advanced to the position above the atomizer.
If desired, the compressed air may be sup-v plied to the orifice l'l continuously and discharged continuously, or, if desired, the plate 21 may be provided with means for closing oiT the flow of air. In the construction shown, the plate 21 serves mainly to deflect air rearwardly and does not prevent the discharge of air.
It will be noted that the recess 22 provided in the block l5 enables the valve plate 21 to extend below the nozzle 2| and to the rear of the air port ll so as to provide a complete separation between the two ports,
The apparatus is extremely simple, foolproof, and it operates effectively and automatically to supply and atomize the liquid when a can surface to be washed is presented above the atomlzer. l i
The foregoing description has been given in detail for the purpose of illustrating one mode of the invention. As already pointed out, considerable variation may be made in the type and structure of the valve employed to close the air supply or to separate the flow thereof from said liquid nozzle. Wide variations in the details may and will be made by those skilled in the art without departing from the spirit of our invention.
1. An atomizer comprising a liquid conduit and a compressed air conduit, an atomizer body communicating with said conduits and providing a substantially vertical air passage and a liquid passage disposed at an angle with respect to the vertical and intersecting at its outlet the outlet of the air passage so that air is discharged across the outlet of the liquid passage, a lever pivotally body and having a 'central mounted on said opening therein above said passages, said lever being pivotally mounted at an intermediate portion thereof and being weighted at its rear end, the other end of said lever extending forwardly and upwardly at'an angle with respect to the horizontal when in normal position and being swingable downwardly from normal position to a lower position when engaged by means mov ing forwardly in a substantially horizontal plane,
and a valve plate carried by said lever and depending from a portion thereof forward of said pivotal mounting, said plate, when saidlever is in normal position, extending downwardly from said lever in a position about said outlet in the the outlet of the liquid passage, a pivotallymounted lever member extending over said out-, lets and having a central opening therein above the outlet of the air conduit, said lever being pivotally mounted at" an intermediate portion thereof, the forward end of said lever extending upwardly at an angle with respect to the horizontal when in normal position and being swingable downwardly from normal position to a lower position when engagedby means movingforwardly in a substantially horizontal plane, and a valve plate carried by said lever and depending from a portion thereof forward ofsaidpivotal mounting, said plate extending downwardly above and on one side of said air outlet and between said outlets when the lever is in normal position whereby the flow of air from said air outlet is intercepted and separated from the liquid outlet, said plate being movable, upon movement ofsaid lever to lower .position,'forwardly and downwardly from intercepting position to a position wherein the plate does not-in tercept the flow of air from said air outlet.
3. An atomizer comprising a substantially. vertical air conduit and a liquid conduit disposed at an angle with respect to the vertical, the outlets of said conduits being adjacently disposed and intersecting so that air is discharged across the outlet of the liquid passage, a pivotally'- mounted lever member extending over said outlets and having a central opening therein above the outlet of the air conduit, said lever being pivotally mounted at an intermediate portion thereof,.the forward end of said lever extend-, ing upwardly at an angle with respect tothe horizontal when in normal position and, being swingable downwardly from normal positionto a lower position when engaged by means moving forwardly in a substantially horizontal plane, and a, valve plate carried by said lever and extending therefrom, said plate, when the lever is in normal position, being disposed between said outlets whereby the flow of air from the air outlet is intercepted and separated from the liquid outlet and being movable, upon movement of said lever to lower position, from said intercepting position to a position wherein the air flow from said air outlet is not intercepted.
