FIRE EXTINGUISHER ATTACHMENT FOR CONTAINERS 0F PRESSURIZED LIQUIDS Filed June 28, 1963 FRANK X. KAMP ATTORNEY U ited States- Patent Ofifice W 3,168,219 Patented Feb. 2, 1965 3 168,219 FIRE EXTINGUISHER ATTACHMENT FOR CON- TAINERS OF PRESSURIZED LIQUIDS Frank X. Kamp, Deposit, N.Y. Filed June 28, 1963, Ser. No. 291,512 2 Claims. (Cl. 222--s2 The present invention relates to a fire extinguisher attachment for containers of pressurized liquid and it consists in the combinations, constructions and arrangements of parts hereinafter to be described and claimed.
Generally there is provided a device which may be quickly and easily mounted upon a bottle of beer, soda, pop, soda Water or other container of liquid under pressure such as absorbed carbon dioxide or the like. The device consists of a shell having a top and a cylindrical dependent side wall. Aflixed in the top is a hollow screw or the like having a penetrating point at its lower end. The device is such that it may be quickly and easily placed over the conventional bottle cap of a bottle or other container having a pressurized liquid therein. Downward pressure upon the shell will cause a penetration of the conventional cap and thereafter the gas such as carbon dioxide contained in the liquid will cause the liquid to forcibly flow through the hollow screw whereupon it may be pointedat the source of a fire to extinguish the same. The device may be used repeatedly with additional containers. Means is provided for maintaining the shell in position during use.
It is accordingly an object of the invention to provide a device of the character set forth which is simple in construction, inexpensive to manufacture and yet effective and efficient in use.
Another object of the invention is to provide, in a device of the character set forth, novel means for penetrating a conventional bottle cap.
Still another object of the invention is to provide, in a device of the character set forth, novel means for retaining the device in position upon a container during use.
Other and further objects of the invention will become apparent from a reading of the following specification taken in conjunction with the drawing, in which:
FIGURE 1 is a side elevational view of an embodiment of the invention,
FIGURE 2 is a vertical sectional view of the device illustrated in FIGURE 1 illustrating the same at one station of its manufacture,
FIGURE 3 is a view similar to FIGURE 2 but show ing the device in its completed state,
FIGURE 4 is a view similar to FIGURE 3 but showing the device mounted upon a bottle having a conventional crimp-type cap thereon,
FIGURE 5 is a perspective view illustrating the manner of mounting the device of the present invention upon a bottle or other container, and
FIGUREG is a perspective view illustrating the manner of use of the device of the present invention.
Referring more particularly to the drawing, there is shown therein a fire extinguisher attachment for containers of pressurized liquids comprising a shell having a circular top and integrally formed dependent cylindrical side walls 11 having a plurality of inwardly extending indentations 12 formed therein and having an outwardly extending flange 13 at the lower end thereof.
A cylindrical member 14 of relatively small diameter is centrally provided with a passageway 15 and with an integrally formed collar 16 adjacent its upper end. The member 14 extend centrally through the top 10 with the collar 16 abutting the underside of the cover 10. That portion 17 extending through the top 10 is flattened by swaging or riveting, as shown in 18, in FIGURES 3 and 4 to secure the member 14 to the shell. Thereafter a circular gasket 19 is positioned around the member 14 in abutting relation to the underside of the top 10 and it will be seen that the member 14 is provided with a sharpened lower end portion 20.
In operation, it will be apparent that when a fire occurs and it is desirable to utilize the instant device, it is only necessary to place the same over the conventional crimped cap 21 of a bottle 22 (see FIGURE 4), it being understood that the container 22 holds a liquid such as soda water or the like being under pressure from contained carbon dioxide or the like. Downward pressure upon the device as, for example, by the thumb of the operator or user as shown in FIGURE 5 will cause the sharpened end 20 to penetrate through the crimped cap 21 after which it is only necessary to agitate the container 22 causing the gases contained in the liquid to force the liquid through the passageway 15 whereupon the flow of liquid may be directed at the source of the fire as illustrated in FIGURE 6.
It will be understood that the device may be made of a proper size to fit over one end of a conventional beer can, the operation in such case being identical with that above described. It will be apparent that when the device is mounted upon a container that the indentations 12 will engage with the conventional cap 21 to maintain the device thereon until it is desirable to forcibly remove the same utilizing the flange 13 for such purpose.
While but one form of the invention has been shown and described herein, it will be readily apparent to those skilled in the art that many minor modifications may be made without departing from the spirit of the invention or the scope of the appended claims.
What is claimed is:
1. In combination with a bottle containing fluid under pressure and having a crimp type cap, the provision of a shell having a circular top and dependent cylindrical side walls engageable over said cap, said shell being provided with a gasket abutting the underside of said top, a hollow cylindrical member having a constricted bore centrally aflixed to and extending through said top, said gasket surrounding said hollow member, and said side walls being provided with a plurality of inwardly directed indentations for engagement with said cap to retain said shell on said cap, said hollow member having a sharpened inner end for effecting a single perforation in said cap whereby to permit escape of the pressurized contents of said container through said constricted bore without the admission of air, and said hollow member being provided with an integrally formed collar adjacent the underside of said top and said hollow member terminating immediately outwardly of said top in a flattened top portion whereby to clamp the hollow member firmly to said top.
2. The combination as defined in claim 1 wherein the inner end of said hollow member terminates above the lower edge of said side walls.
