This invention relates in general to a perfume or liquid sprayer or atomizer One of the objects of this invention is the pro-vision of a simple device of this nature in the form of a small portable article.

Another object of this invention is the tainerfor the fluid, and means for spraying the fluid which means is operable with one hand. v p

Another object is the provision in mechanism of the above type, of an operating handle and a closure member for sealing the liquid discharge port, and: means for locking both in closed position.

& still further object of his invention is is released by pressing down on the handle to free the cover.

A still further object of this invention is the provision of an operating handle and 30 closure member mounted upon the piston rod; of the air pump.

These and other objects as will appear from the following disclosure are secured by means of this invention.

Fig. 3 is a side elevational view with a portion of thecontainer brokenaway and some of; the'parts removed; and

Fig. i is across sectional view taken on the line 4-4 of Fig. 2. 1

The invention will best be understood by direct and detail reference to the drawing. It comprises a containershell 1 closed at the ends by the cover p ates 2 and 3. On

2a the provision of the catch mechanism which The invention resides substantially in the the upper cover-plate 3 are two upright parallel plates 4; between which the mechanism operates and by means of which the partsare partially hidden. At 5 is a threaded block which screws into an opening in the top cover plate through which opening thefiuid is introduced into the container. Opcrating through the top cover plateis a square piston rod 9 upon which isrigidlymounted the operating handle 6. Pivot-ally supported on a. pin 8 mounted: on the piston rod is a cover 7. As shown. in Fig. 4 aucoi'l spring 10 encirclesthe pivot. pin 8-,. and has one end 11 lying against the fixed. handle. 6'. The pivotally supported cover 7 is provided with an inwardly projecting lug 12 against which the. other end. 13 of. the spring lies. 'Projecting downwardly within the cover 7. is a hook 14.- whichengages. a catch 15. fixedly supported on thecover plate 3. Mounted within the container as shownin. Fig- 3, is a small metal cylinder 16. withinv which moves the piston. 19 secured to thepiston rod 9 and provided with a suitable packing cup of soft leather or rubber 18..

Lying within the cylinder 16 between. the

piston and the bottom of the container is coil spring 17. Connected to the lower end. of the cylinder is a very small tube 20 which has a very fine bore. The upper end of this tube passes through, thecover plate 3 and terminates in a pointed end 21. At 22' isa similar small tube extending close to the bottom of the container at one end. and projecting through the cover plate to provide an exposed .end ;23.- Another small. bore 24 projects through the cover for a short distance on each side thereof: Withinthe cover 7, as shown in Fig. 4 is a soft .rub-

ber block which is secured-therein. in such:

a position asto press down over the end. of

tube 24 and the ends 21 and 23 of tubes. 20.

device is closed as shown in Fig. 1, the operator presses down on handle 6. This causes the piston 9 to move downwardly as well as cover 7. The lower end of the hook 14 which is rounded engages with the top cover plate 3, and as pistonrod 9 and pivot pin 8 continue downwardly the cover 7 rotates about its pivot pin under the fulcrum ing action of hook 14 on the cover plate. When hook 14 moves out of engagement with stop 15, spring 10 which is under tension causes cover 7 to fly upwardly. The release of pressure on handle 6 then permits spring 17 to move the piston rod 9 and all the parts mounted thereon upwardly to the position shown in Fig. 3. The operator then presses, usually with his thumb, downwardly on handle 6 in rapid strokes causing the piston toforce air up throughtube 20 and out of the end 21. The end 21 is positioned so that the fine air blast is directed across the end 23 of tube 22. The rush of air across the end of this tube creates a vacuum in tube 22 and the atmospheric pressure pressing on the liquid through tube 24 permits the liquid'to rise to the end 23 of tube 22, from which it is blown in a fine spray by the air blast from tube 20. The tube 24 which opens the interior of the container to the atmosphere serves to maintain atmospheric pressure therein at all times. When the operatoris through with the device he places his finger so as to engage both the handle 6 and the cover 7 and presses down on them until the parts are moved to the position where hook 14 engages stop 15. When the pressure is released'the parts remain in the closed position shown in Fig. 1.; When the cover is in closed position as shown in Fig. 4, the soft rubber block 30 engages the openings of tubes 24, 22 and 20, particularly 24 and 22 to seal them so that the liquid cannot escape. Tube 20 should preferably have long smooth'curves at each end to aid in cleaning the tube.

From the above description it will be apparent that my invention resides in certain principles of construction and operation which may be embodied in other physical forms, and I do not, therefore, desire to be strictly limited to the disclosure given for purposes of illustration, but rather to the scope of the appended claims.

What I seek to secure by United States Letters'Patent is:
