Application mea Apni 1a,

This invention relates to sprayers and more particularly to a sprayer adapted to be actuated by iiuid pressure and by means of which plants may 'bei sprayed to destroy insects which are injurious to them.

One object of the invention is to provide a sprayer including a receptacle to contain fluid under pressure and a companion receptable to receive liquid to be sprayed upon the plants and adapted to have its walls acted upon by the fluid under pressure whereby the liquid may be forced out of its receptacle and caused to be sprayed upon the plants.

Another object of the invention is toA connect the liquid containerwith a head for the iiuid container whereby the liquid container may be supported in the fluid container and veasily withdrawn therefrom when the head of the fluid container is removed.

Another object ofthe invention is to provide the head of the fluid container with a sleeve serving as means for supporting the liquid container and also as means for engagement by the coupling of a hose through which the liquid is to be forced to aispraying nozzle.

. Another object of the invention is to prevent excessive crumpling of the liquid container when empty.

Another obj ect of the invention is to prevent danger of the liquid container closing an inlet for the fluid container.

Another object of the invention is to rovide a sprayer of the type specified w 'ch may be easil taken apart and after being thoroughly c eaned reassembled.

The invention is illustrated in the accompanying drawings, wherein Figure 1 is a view showing the improved elevation;

Fig. 2 is a longitudinal sectional view through the sprayer;

Fig. 3 is a transverse sectional view taken through the sprayer on the line 3--3 of Fig. 2; y

Fig. 4 is a transverse sectional view through the sprayer taken on the line 4-4 of Fig. 2, and

Fig. 5 is la fragmentary perspective' view showing the guard for the inlet of the fluid container. f

The bodyv portion or container 1 of the sprayer is preferably formed of metal although other materials might be found suitable and at one end is provided with a head 2 having a neck 3 projecting therefrom 1927. Serial. No. 183,179.

and internally threaded for engagement with the outlet neck of a control valve 4. The valve 4 is of a conventional construction and adapted to have a hose 5 connected with itsv inlet end so that water or other fluid under pressure may be fed into the body portion or iuid container 1. At its other end the container is provided with a head 6 from which extends a large neck or collar 7 threaded so that a cap 8 may be screwed thereon. When the cap is removed, easy access may be had to the interior-of the container through the opening enclosed by the neck or collar 7 A sleeve 9 extends through the center of the cap 8 and has one end portion projecting inwardly and internally threaded, as shown at 10, and its other end portion projecting outwardly and externally threaded, as shown at 11, for engagement by the coupling 12 of al hose 13. The hose 13 may be of any length desired and at its outer end carries a nozzle 14 from which liquid may pass in a spray and be directed upon the plants.

Within the uid container 1 is disposed a liquid container 15 which ma be referred to as a bag if so desired and is ormed of flexible material, such as rubber, rubberized fab y ric or the like, so that the bag or receptacle 15 may be colla sed by the action of the water or other uid under pressure in the receptacle 1 and liquid placed in the bag forced out of it. A neck 16 extends from one end of the bag 15 and fits about a nipple 17 where it is secured by a clamplS-which is of a conventional construction and similar to the clamps 19 employed at the ends of the hose 13. The nipple 17 projects into and out of the bag an has its outer end portion externally threaded so that it may be screwed into the internally threaded innerend portion of the sleeve 9.- It is desired to prevent the bag from crumpling into a very compact mass within the fluid container 1 and in order to do so there has been provided a support 20 formed of wire bent intermediate its length to provide arms 21 extending from a bridge 22 and havin their end portions 23 lbent to extend towar each other. The end portions 23 of the support are passed through 'openings 24 formed in the nipple 17 and have their extreme ends bent, as shown at 25, to prevent the arms from slipping out of the openings in the nipple. It is preferred to have the support formed 'of resilient wire so that the arms will have a tendency to spring away from each other and thereby retain the support in proper engagement with the nipple. By referring to Fig. 2 it will be seen that the support will very effectively serve to prevent the bag from crumpling into a compact 'mass in the forward end portion of the container 1 where it is liable to have portions of its walls stick together. A guard plate 26 is provided to prevent danger of the through the neck to be directed toward the sides of the container instead of striking the bag in a solid stream.

When the sprayer is in use, the coupling 12 of the hose is released and the liquid which it is desired to spray upon the plants is poured into the bag through the sleeve 9 and.v

nipple 17 after which the coupling is again connected with the sleeve. lt will, of course, be obvious that, if desired, the cap 3 could be unscrewed and detached from the nipple 17 so that the liquid could be poured directly into the nipple. When the liquid is poured into the bag, the operator opens the valve 4 so that water may pass from the hose into the container 1 and accumulate therein about the bag. The valie 4.- will, of course, be `opened according to the pressure desired an the pressure of the water in the container 1 will tend to collapse the bag and force the liquid through the hose 13 until the bag has f been emptied of liquid. This liquid passes from the nozzle of the hose in a spray and, therefore, rosebushes, vines or trees may be very easily sprayed to protect them from insects or the like. It will be obvious that, if desired, the valve 4 could be engaged with the sleeve 9 and the hose 13 connected with the neck 3 so that the liquid to be sprayed could be poured into the container 1 and the fluid under pressure fed into the bag to expand it and force the liquid out of the container 1. In either case, the apparatus would include companion receptacles or compartments, one having flexible walls adapted to be acted upon by fluid under pressure so that liquid in the other compartment or receptacle would be forced out of it. While it has been stated that the device is used to spray plants, it willbe understood that it may also be used to spray medicines, disinfectants vand the like upon animals, chickens and other fowls or buildings in order to kill or drive vermin away. llt may also be used to spray paints or any other fluid desired.

Having thus described the invention, ll claim:
