ATTEIRN EYS Unitfid States Patent AUTOMATIC FIRE EXTINGUISHER Leonard C. Deyo, Lewiston, Idaho, assighoi' of one-half to E. N. James, Lewiston, Idaho Application-July s, 19s3, seria1 N6. 366,660

3 Claims. Cl. 169-26) This invention relates to fire extinguishers particularly adapted for individual use, such as in the home, in a motor vehicle, boat or airplane, and in particular a cap having a fusible or readily breakable element incorporated therein with the cap adapted to be crimped over the bulge on the neck of a bottle and with the element adapted to release a closure on the neck of the bottle when fused or broken.

The purpose of this invention is to provide means for forming a fire extinguisher with a conventional container, such as a bottle and in which the same container may be refilled and reused by crimping a new cap thereon.

Conventional types of fire extinguishers are comparatively costly and for this reason they are very seldom used in motor vehicles, residences, small boats and the like. With this thought in mind this invention contemplates a method of forming a fire extinguisher whereby a bottle containing fire extinguisher fluid may be sealed with a cap having an element therein that is readily fused or broken to release the cap.

The object of this invention is, therefore, to provide a cap adapted to be mounted on the neck of a bottle or the like whereby with the bottle filled with a fire extinguishing fluid the fluid may be sealed in the bottle and released only upon fusing of an element or upon manually breaking the element.

Another object of the invention is to provide a cap for sealing a bottle containing fire extinguishing fluid in which the cap is adapted to be used on bottles now in use.

A further object of the invention is to provide a fire extinguisher formed with a sealing cap on a conventional bottle in which the bottle is adapted to be covered with plastic or the like to change the appearance thereof.

A still further object of the invention is to provide a fire extinguisher which is of a simple and economical construction.

With these and other objects and advantages in view the invention embodies a fire extinguisher cap including a tubular casing, preferably of copper, and adapted to be crimped over a bulge on the outer surface of a neck of a bottle, a disc having an annular flange freely positioned against the end of the neck of the bottle providing a closure and a disc freely hinged in the end of the outer casing and adapted to be secured in position with a fusible element and wherein upon fusing or breaking of said element the disc providing the closure is released to release fluid in the bottle.

Other features and advantages of the invention will appear from the following description taken in connection with the drawing, wherein:

Figure 1 is a side elevational view showing the improved fire extinguisher with the lower portion of a cap on the end of a neck of the container of the extinguisher broken away showing the disc for releasing the closure of the container in the sealing position in full lines and 1n the released position in broken lines.

Figure 2 is a vertical section through the fire extinguisher taken on line 2-2 of Fig. l.

"ice

Figure 3 is a view looking upwardly toward the lower end of the fire extinguisher.

Figure 4 is a plan view of the fire extinguisher.

Figure 5 is a detail illustrating the cap of the fire extinguisher looking toward the side thereof on which the disc is hinged andshowing a portion of the neck of a bottle in broken lines.

Figure 6 is a detail illustrating the flanged closure member of the extinguisher.

Figure 7 is a detail illustrating the releasing disc by which the closure member is retained in position on the end of the neck of the bottle.

Referring now to the drawing wherein like reference characters denote corresponding parts the improved fire extinguisher cap of this invention includes a sleeve 10 having an opening 11 in one side and adapted to be positioned over a bulge 12 on a neck 13 of a bottle 14 with the upper edge of the sleeve crimped over the bulge 12, as indicated at the point 15 and, as shown in Figs. 1 and 2 a closure 16 is retained in sealing relation with the end of the neck of the bottle with a disc 17, a prong 18 of which extends through the opening 11 of the sleeve and a flange 19 of which, that is positioned on the opposite side, is secured to the edge of the sleeve 10 with a fusible element 20, such as woods-solder or metal.

The closure E6 is provided with a web 21 and an annular flange 22 and this member is retained in position, as shown in Fi 2 by the disc 15 that is hinged in the opening 11 with a prong 1S and as the fusible element 2% is fused or broken the disc 17 drops downwardly as indicated by the broken lines in Fig. l with the prong 13 dropping from the opening 11 whereby the closure 16 is released so that it drops from the neck of the bottle and with the closure in removed fire extinguishing fluid, as indicated by the numeral 23 may be used from the bottle in the conventional manner.

In the design shown the bottle is provided with a hanger formed with an annular band 24 with

arms

25 and 26 extended upwardly over the upper end of the bottle. The upper ends of the arms are provided with flanges 27 and 28, respectively and a hook, nail, or other fastener as indicated by the numeral 29 may be placed through openings in the flanges to support the fire extinguisher.

The arms 25' and 26 are provided with bulging sections 39 and 31, respectively and openings with tapering upper ends, such as keyhole slots are provided in the bulging sections as indicated by the numeral 32. By this means the fire extinguisher may be placed over the head of a nail or other fastener.

Also, as illustrated in Fig. 2 the bottle or container may be covered with a layer of plastic, as indicated by the numeral 33 to change the color of the container or improve the appearance thereof.

Although it is preferred to use an element, such as the element 2t), that will fuse at a temperature of degrees B, it will be understood that other suitable fusible materials may be used and materials may be provided to fuse at different temperatures.

It will be understood that modifications, within the scope of the appended claims, may be made in the design and arrangement of the parts without departing from the spirit of the invention.

What is claimed is:

l. A fire extinguisher cap comprising a closure including a web having an annular flange and adapted to be positioned on the end of a neck of a bottle, a sleeve positioned around said closure and adapted to be crimped on the neck of the bottle, a disc hinged in the lower end of said sleeve, and a fusible element connecting the sides of the disc opposite to the side on which the hinge is positioned for retaining the disc in the sleeve with the disc adapted to retain the closure against the end of the neck of a bottle upon which the sleeve is crimped.

2. A fire extinguisher comprising a bottle having a neck with an annular bulging section spaced from the end thereof, a sleeve having an opening in 7 one side thereof positioned over the neck of the bottle and crimped over the annular bulging section thereof, a closure having a web with an annular flange thereon positioned over the end of the neck of the bottle and surrounded by said sleeve, a disc having a prong extended through the opening in the sleeve and positioned against the closure on the end of the bottle, a fusible element temporarily connecting the disc to the sleeve at a point opposite to that from which the prong extends, and a hanger positioned on the upper end of the bottle.

3. A fire extinguisher comprising a bottle having a neck with an annular bulging section spaced from the end thereof, a sleeve having an opening in one side positioned over theneck of the bottle and crimped over the annular bulging section thereof, a closure having a web with an annular flange thereon positioned over the end of the neck of the bottle and surrounded by said sleeve, a disc having a prong extended through the opening in the sleeve and positioned against the closure on the end of the bottle, a fusible element temporarily connecting the disc to the sleeve at a point opposite to that from which the prong extends, a coating covering the outer surface of the bottle, and a hanger on the bottle.
