man EXTINGUISHER.

Application'led April 8, 1921. Serial No. 459,679.

following is a full, clear, and exact description'` l This invention relates to containersv and refers more particularlyto animprovement in containers for lire extinguishing fluids, the same being'in the nature of an improvement over my co-pending applicationv filed August 18th, 1920 and bearing Serial No. 404,459.

"As stated in my former appli-cation, thc principal object in view was to provide a simple and inexpensive package or container which was destructible by fire whereby the same could be used as 'va bomb to be thrown directlyinto the flame for exting- `guishing the same. A further 'aim and object sought was toV provide :a frangible closure which could be readily-broken withth-e lingers to permit of'use in the usual ymanner by emptying the contents onto the flame.

The improvement constituting the present invention contemplates like objects and the addition thereto aims to provide a package provided with fusible portions and a frangible and fusible covering together with protective means for the fusible portions to prevent accidental destruction of the same during shipment or handling thereof.

A further object in view resides in the provision of a package or container for fire extinguishing fluids which is also operable to sprinkle the contents over the liame by pressure developed by expansion of the contents under the action of heat.

a With the above recited and other objects in view, the invention resides in the novel construction, combination and arrangement of parts set forth in the following specification, pointed out in the appended claims and illustrated in the accompanying drawings, in which; f

Figure 1 is a vertical sectional view through a container constructed in accordance with the invention.

l Figure 2 is a horizontal sectional view therethrough taken approximately. on the line 2 2 of Figure 1.

Figure 3 is a side elevation partly in section illustrating a modified form of the invention. y

Figure 4 is a horizontal sectional view therethrough taken approximately` on the line %4 of Figure 3. y

Referring to the drawings by characters of reference, 1() designates a cylindrical tubular body preferably constructed of a think cheap metal such as tin plate or cardboard or any other suitablematerial adapted for the purpose.

Vhere cardboard or otherfmater'ial which would deteriorate under the action of i the'ire extinguishing fluid, is used the inner.

walls thereof will be coated with a suitable substance for resisting the same. 'As illustrated the lower end ofthe container body is closed by means of a cover or 4cap 11 permanently attached thereto'by soldering; clinching or anyfdesired method. The upper end of the container body is provided with a similar cover or cap 12 provided with a central filling -opening 13 which is'designed to receive the lid 14. The lid 14 which yis preferably constructed of tin is provided with a central opening 15 covered by a lead discl secured to the under side thereof. The disc.

16 is preferably constructed of very thin material which renders the Samefrangible by the forcible insertion of the ingersor, a sharp instrument through the opening. 15. The container body 10' is provided with a plurality of openings 17 therethrough which are filled with solder 18 or any other fusible material which lmay be employed foi` .closing the openings 17 and. rendering the same fluid tight.

By this construction it will be seen that a comparatively cheap and inexpensive container is produced which may be used as a gre-- nade or bomb to be thrown into a fire which will automatically fuse to discharge and distribute the contents over the flames for eX- tinguishing the same. It is also obvious that the container may be employed in the usual manner by breaking the frangible covering disc 16 in the lid fr pouring the con tents onto the flame.

In the modified form of 'the invention illustrated in Figures 3 and 4, the container consists of an inner cylindrical receptacle or body 2O having an integral bottom 21, the same being preferably constructed of thin lead or any other suitable material hav'- drical body 22 is closed by a metal cap 28 which houses and protects the bottom wall 2l of the inner receptacle Q0. The upper end of the inner receptacle is closed by a covering disc 29 of lead or a similar material and the inner receptacle 2O and said covering dise have the peripheral edges thereof bent outwardly and clinched between the bead 30 formed on the peripheral edge of the metallic cap 3l which closes the upper end of the outer body 22. The cap 8l is centrally apertured at 32 to afford an opening through which the fingers or a suitable instrument may be inserted 'i'or breaku ing the covering disc 2) when it is desired to empty the contents of the container. By this construction the container be einployed as a grenade or bomb which when thrown into a flame or fire will present the portions of the inner ycontainer exposed through the aligned openings through the action of the flame whereby said portions may fuse to distribute the contents thereover for extinguishing the same. The outer card board layers may be treated with a suitable substance to render the saine more readily combustible when thrown into the fire in order to augment or quicken the Afusing of the inner receptacle and discharge of the contents.

lVhile there has been illustrated and described several. preferred embodiments of the invention, no limitation is necessarily made to the precise structural details as it is to be understood that variations and modifications which properly fall within the scope of the appended claims may be resorted to when found expedient.

I claim:

1. A fire extinguisher including aninner fusible and frangible container, a lire extinguishing fluid therein, and a protective shell therefor consisting of inner and outer layers having aligned perforations, and an intermediate foraminous layer which serves to cover the aligned perforations of the shell layers.

2. A fire extinguisher including an `inner container filled with a fire extinguishing fluid and closed at its opposite ends by end walls, said container and end walls being constructed of a material which is frangible and destructible by fire,.and an outer protective shell having openings therein and completely housing the inner shell.

3. A lire extinguisher including an inner container filled with a fire extinguishing fluid and closed at its opposite ends by end walls, said container and end walls being constructed of a material which is frangible and destructible by fire, and an outer protective shell lhaving openings therein and completely housing the inner shell, said outer shell consisting of inner and outer layers of material having aligned perforations and an intermediate layer of foruminous material, portions of which extend over the aligned perforations.
