i`Y claim. 1

This. invention relates to2-a home-rechargeable liquid wax insecticide or reeii-ghting ui'dbomb.

It isan: object of." the present invention to. pro- Yd'earuid bomb which canr be rel'led at home when emptied: instead of" havingAv to be; returned to the dealer ory factory'and' whereby to provide ay bomb.I which is-i less expensive: to; use.

It. isanother object,l of the present` invention td provide the userA of*` the; bombi with a. handle and; to, render.: the bomb more safe in that. the iiuich as: the; bomb is carried by` the: handle,y will be. sprayed directly away. from the.y user.'

It is another object?. of the present invention to provide; a fluid bomb adapted for home; use. wherethe, user, ofthebomb. can.l insert different fluids thesame: and thereby; eliminate the necessity of, having different: bombs for difierent uses. and wherein a bomb will have a separable gasachargingrI cartridge whichv will be disposed within the interior of the bomb instead of outside thereof whereby to eliminate; the possibility of gas blowing back into the users face as. may happen when the cartridge is locatedA on the` outside of the bomb.

Other objectsA of the present invention are to provide a home rechargeable liquid wax, insecticide; and re-ghting fluid bomb which is of, simple; constructionL inexpensive to manufactureL convenient to use, easy;v to'fill and'. charge, and eflicient in operation.

Forother objects and for a; better understanding oif'theinventionpreference may be to the following detailed description taken in connection with the accompanying drawing, in which:

Fig; 1' is a vertical sectional view taken through the bomb-embodying the features of the present invention and through. the operating parte thereof.

Fig. 2 is an enlarged sectional view, in elevation, taken through the cartridge chamber and with the cartridge elevated to have its valve depressed to extend the gas into the bomb.

Fig. 3 is an enlarged sectional View, in elevation, taken through the outlet valve structure for the bomb with the button in the depressed position and the valve open.

Fig. 4 is a transverse sectional View taken on line 4-4 of Fig. 3.

Fig. 5 is a fragmentary bottom plan view of the bomb looking on line 5-5 of Fig. l.

Fig. 6 is a fragmentary elevational view of a modied form of top structure with a nozzle extended therefrom.

Fig. 7 is a sectional View, in elevation, of a modied form of cartridge housing including a 2. triangularpronged puncturing element" for` the capsule.

Fig; 8- is a transverse sectional'l view taken on line 8 8y of Fig. '7.

Referring now to the figures, I5 represents.` a container adapted to receive the liquid wax, windowcleaning iiuid, insecticide or fire-iighting iiuid which is to be dispensed by' the same. The upper part of the container is ii'attened as: indicated at I6' to permit the' useof the handle If1 secured thereover;

The bottom of the container is dished' as indicatedV at IB and has securedl to it an internally threaded sleeve I9 adapted toA receive a plug 2-.I having handles 22 thereon. When this plug 2f! is removed from the sleeve I9, access can be had to a capsule or cartridge disposed in a cupshape member 23;- on the inner end ofthesleeve I9 and with a perforated bottomV as indicated'V at 24. The cartridgeis` indicated at 25, This-cartridge has a bushing4 or ball valve structure 26 on its inner end adaptedto` receive a pin 21 on the bottom 24. This pin may extendl intothe ball valve structure forl engagement with ball valve element 23 to-V remove the same f-'romJ the seat against the action of a spring 20. The cartridge 25 is normally maintained in'` itsY non-projected posi-tion by av spring' 3|' which-reactsr against the bottom 24.

The sleeve IB@ has a radially inwardlyvv extending flange 32' against which may restl av dia phragm 33 which seals the cartridge 25 within the sleeve I9. This diaphragm is' backed up with a washer 34 and the plug Z-I. Extending 'through the center ofthe plug 2-I is a pushvbutton 35: having--v an enlarged head 36 which engages with the diaphragm to causethe diaphragm to be pushed inwardly as shown in Fig. 2 for moving the cartridge to the position shown in Fig. 2 whereby the pin 21 will engage with the ball 28 to open the cartridge and to cause the container I5 to be charged with the gas. When suiiicient gas has been let into the container, the bomb is ready for use.

When the plug 2l and the diaphragm 33 and the cartridge 25 have been removed, the desired uid can be disposed in the container I5.

In the top of the container there is depressed inwardly a sleeve portion 38 adapted to receive a cup-shaped member 39 having a flange 4I resting on the top of the container and secured thereto by solder 42. The upper end of the cup-shaped member is externally threaded as indicated at 43 to receive an inverted cup-shaped member 44 which can be screwed thereupon.

Within the member 44 is a plug 45 having a central opening 46 through which extends a pin 41 adapted to engage with a ball 48 which is normally maintained on its seat 4S by a spring 5| disposed within the member 39 Extending from the bottom of the member 39 are liquid tubes 52 and 53 having respectively screened ends 54. On the upper end of the plug, there is a diaphragm 56 which provides a seal. The pin 41 extends to the diaphragm. Above the diaphragm is a plate 51 through which may be operated a push button 58 having a pin projection 59 adapted to engage the opposite side of the diaphragm 56. The ring 6l serves to retain the push button within the ends of the member 44.

Within the plug 45 is an annular groove 62! to which fluid is dispensed through a radially extending passage 64 from the opening 46 as the ball 48 is depressed. In the member 44 is an outlet opening 65 at the level of the groove 62 through which the iluid will be discharged to the atmosphere. The button 58 can be reached kwith the thumb while grasping the handle I1.

The plug 45 can be held against rotational displacement within the member 44 by keys 61. Fig. 4.

[In the design shown in Figure 6, which is particularly adapted for re extinguishing fluids, a container 61 is provided with a cup-shaped member 68, similar to the member 44, and this member is provided with a fire nozzle or nipple 69 through which the fluid may be ejected or sprayed as a button '10 on the upper end is pressed downward.

The design illustrated in Figures 7 and 8 is particularly adapted for a cartridge of the bottle neck type and the container is provided with a sleeve 1l similar to the member 23, and the upper perforated end 12 thereof is provided with a three .cornered prong 13 that extends downward to engage and puncture the upper end 14 of a cartridge 15. The cartridge is held downward by a spring 16, similar to the spring 3| until it is forced upward by the pin 35. The lower end of the cartridge 15 is provided with a filling opening 11 ina threaded neck 1=8 and the opening is provided with a closure or plug 19, as shown.

It will be understood that although the device has been described as a bomb it may be used for liquid wax, insecticide, window cleaning fluid, fire extinguishing iiuid, or any substance desired, and any suitable means may be provided for creating or Kproviding pressure therein.

It will .also be understood Ithat modiiications may be made in .the design and arrangement of the parts without departing from the spirit of the invention.
