ATOMIZER Filed April 5, l192'? Patented Nov. 26, 1929v Y UN'TD STATES MARCEL CUEL, OF PARIS, FRANCE, ASSIGNOR TO lSOCIETE DU VAPOBISATEUR LE. FRIS- SON, OF PARIS, FRANCE m ATOMIZER Application filed April 5, 1927, Serial No. 181,095, and in France June 18, 1926.

This invention relates to atomizers of the manually operable type. The object of the invention is to provide an atomizer having provisions for hermetically closing the receptacle to which it is attached by a simple adjustment and for easily clearing the atomizing tube of foreign matter, whenever' it becomes desirable to do so. Other subsidiary objects and advantages of the invention will become apparent hereinafter.

Referring to the accompanying drawings: F ig.v 1 is a vertical sectional view through the atomizer;

Fig. 2 is a perspective view of a stopper which forms part of the atomizer; v

Fig. 3 is a view similar to Fig. 1, but showing the stopper in a different angular position' Fig. 4 is a horizontal section through the atomizer showing the stopper in still another position; and

Fig. 5 is a detail view of the stopper seat. The atomizer comprises a cup 1 formed of metal or other suitable material and adapted to lit over the neck of a bottle or other receptacle in which is contained the supply of liquid to be atomized. The cup l has a thickened upper end in which is formed a conical bore the axis of which is offset laterally from so the axis of the cup, an opening 3 being formed in the wall of the bore at one side and a passageway 4 opening into the bore at a diametrically opposite point. The passage-V way 4 opens at its outer end into a bore in S5 which is secured one end of a rubber tube 6, the other end of which is adapted to be secured to a rubber bulb.

A stopper 2 has a nice fit with the bore in cup 1. This stopper is formed with a notch l0 15 adapted to register with opening 3 or with the passageway 4 and is also formed with` a slot 13 opening at the side and bottom of the stopper and extending to about the center axis of the stopper. The recess 15 is connected Ll5 with the slot 13 by a threaded hole and in this hole is adapted to be screwed the end of an atomizing tube 16, formed with a small aperture 17 in its side near the upper end. The tube 16 is straight before it is assembled with the stopper, being rst screwed into the threaded hole in the stopper.v and -then bent to the position shown in the drawings. The

handle of the stopper is formed with a laterally projecting lug 18' which is adapted to abut shoulders 19a and 19b formed at` the upper end of the cup shaped member 1. These shoulders permit the stopper to be rotated through anl angle of about 270.

Fig. 1 shows the atomizer in operative posi. tion' andthe operation will beV obvious. By operating the bulbnot shown, air is pumped through tube 6 and passageway 4 into the receptacle to which the atomizer is applied, forcing the v liquid contained therein up through tube 6, where it is broken up and atomized by air entering the restricted opening 17 and issues from the extremity 14 of the tube in a fine spray passing out through the aperture 3 in the member .1. In this position of the parts lug 18a is engaged with In atomizers of this type it shoulder 19". frequently becomes necessary to clear the atomizer tube 16 of foreign matter, and it is one ofthe main objects of the present invention to render this clearing operation effective and easy to carry out. According to the present invention clearing of the tube 16 is eected by rotating the stopper 2 from the operative position shown in Fig. 1 to the position shown in Fig. 3. In this position the recess 15 in the stopper and the opening of tube 14 registers with passageway 4, and the tube 16 can be effectively cleared of foreign matter by operating the bulb and forcing air through the tube 6,.,passageway 4 and tube 16. This current of air will force out any foreign matter in the tube, and the air thus pumped through the tube will escape through the opening` 17 and the bottom of the tube and to the outside of the receptaclethrough slot 13 and opening 3. The tube 16 can thus be easily cleared at will without disassembling the parts. I/Vhen the stopper has been turned to the position kshown in Fig. 4, which is about 270o from the position shown in Fig. 1, lug 187L engages shoulder 19a, this being the position of the stopper when the atomizer is not in use. It will be observed that in this position, the stopper hermetically shuts olf communication with the interior ofv the tube either through assageway 4 or through aperture 3, thus e ectively preventing evaporation of the liquid in the receptacle.

What I claim is: Anatomizer comprising in combination,
