This invention relates generally to the art of applying insecticides, and articularly to a special form of gun where dhst can be applied in a convenient manner. The main object of. this invention is to provide'an exceedingly simple and efficient form of dust gun whereby powdered insecticide may be applied in remote and inaccessible places by a very simple operation.
The second object is to so construct the gun that-it can also be used as a cheap and convenient container in whichinsecticide can be sold. The third object is to provide a special form of valve which will be easy to cons'truct and infallible in operation. These, and other objects, -willbecome more apparent from the specification f olowing as illustrated in the accompanying 2o drawing, in Which:',
Figure 1 is a longitudinal section through thedeviceshowing. it extended and taking air in. at its inlet end. Figure 2 is a similar view showing the gun in a closing posi- ,tion with dust being ejected from its discharge end. Figure 3 is a perspective view of the inner valve disk. Figure 4 is an elevation of the .inner valve disk. Figure 5 is a section taken along theline 55 in Figao-ure 4. Figure 6 is a section taken along the line 6-6 in Figure 1. Figure 7 is a section taken along the line 77 in Figure 1. Fig- 1 ure 8is an elevation showing the shape of 'the discharge nozzle- Similar numbers of reference refer. to similar parts throughout the several views. Referring in detail to the drawings, the gun. consists of two principal parts, the 'first being the container and the. second the air injecting tube. The container consists of a "cardboard tube placed a cap 11 of check valve of sheet rubber and is cemented'to the cap 11 on three sides leaving the side 13 in con- ,tact with the cardboard, but not attached thereto. The opening 14 over which the rubber 12 is placed is preferably'flanged toward the rubber sheet 12 for the purpose of provided with a; unique form making a better contact therewith.
,of a fairly heavy piece of rub er whic 10 in "one end of which is 1928. Serial no. 287,990.
At the other end of the tube 10 is'mounted' a closure 15 w "ch is, in reality, mounted upon a separate tube 16, which, in turn, is secured tothe tube 10. In the closure 15 is also mounted a dust discharging nozzle 17 whose tip 18 is flattened to" form a better shape for'the outlet. The nozzle-17 is also provided with perforations 19 on its under side and a port1on20 of the nozzle 17 is inturned to form an obstruction within the nozzle 17. The nozzle. 17 is cemented in the inwardly flanged opening 21. f
he air injecting tube consists of a tubular cardboard member 22 similar in diameter to the tube 16, but slidably mounted on the tube 10. 7 Over the end of the tube 22 is secured a cover 23 on the middle portion of which is formed a flapvalve24, referabl merely hinges .onthe fastening staple 25;- whereas the member 12, which is also rubber, must actually stretch before air can pass through the opening 14. v
Powden 26 is placed in the tube 10 either through one end or the other, whichever may I6 be most convenient, and the members 11 and 15 securely fastened. Any extending action of the air injection tube 22 causes air to pass inwardly through the o ning 27, and a movement in the opposite dii 'ection causes the flap valve 24 to close and the air to be compressed within. the tube 22 between the ends 1L and 23 until the pressure is sulficient to unseat themember 12 and allow air to ass through the opening 14 and to blow pwardly through the powder 26 thereby agitating same andcausing a dustladen air to pass through the opening 19 and to be discharged from. the tip 18.
It will be noted that while the opening 27 is in the center of the member 23, the o n- T in 14 is at one'sid f th tube 10 hi1 the 12 which is preferably made d' e o e e lscharge nozzle 17 is at the opposite'side thereof. In operation the discharge nozzle is always held uppermost which naturally causes the opening 14 to lie/lowermost and insures a thorough agitation of the insecticide.. L 3 I am aware that man forms of dust spra ing devices have been constructed in e" past; it is therefore not my intention to cover such devices'broadly, but I do intend to cover all such forms and modifications thereof as fall fairly within the appended claims.
I claim:
1. A container for insecticides consistin of a tubular member having a closure at eac end thereof, one of said closures having a spray nozzle mounted at one side thereof 10 parallel to the'axis of the tube, said spray nozzle consisting of a cylindrical member having a flattened tube'extending upwardly through said closure, the inner portion of said nozzle haying perforations formed therein, a flanged opening formed in the opposite side of the opposite closure member having its flange extending inwardly, a sheet rubber secured along three sidesover said opening the fourt-hside lying along the outer portion of the container, and means for forcing air through said flanged opening into the interior of said container; 7
2. In a dust gun the combination of a tuhular paper container having a cylindrical cap mounted overone end thereof, one end of said cap being closed and having a round opening formed along one side thereof, a tubular nozzle mounted in said opening one end of which projects into said gun and is provided .30 with perforations and the other end of which projects out of said gun and is flattened, a closure for the opposite end of said tube consisting of a flanged disk adapted to fit inside of said tube end, said flanged disk having a a flanged opening formed at one side thereof on the opposite side of said tube from which lies said nozzle, said flange extending inwardly'into said container, a check valve for said flanged opening consisting of a piece of 40 flexible rubber secured over said opening on the inside of said disk. along three sides of said sheet of rubber'leaving one unsecured side toward the rim of said disk, and an air injecting means consisting of a slidable tubu- Ian cap member mounted on the end of said container op )osite its nozzle, said cap having a closed hear provided with a'fl'anged opening adapted to'open under-external pressure and to close under internal pressure. to 3. A nozzle for spray uns consisting of a tubular cardboard mem er having one end thereof flattened to form a tip and having one side of the tubular portion perforated, a portion'of said perforated side turning in- ---'v wardly to form a closure for the inlet end of the nozzle, said closure portion having inlet apertures formed therein, a portion of said tubular cardboard member extending beyond said inlet end to form a shield therefor. rm, I HAROLD O. HUNTINGTON.
