Application filed January 13 T all whom it may concern.
Be it known that l, HAROLD A. Bellman, a citizen of the United States of America, residing at Providence, in the county of Providence and State of Rhode Island, have invented certain new and useful Improvements in FireExtinguishers, of which the following is a specification.
The object of my invention is to provide a simply constructed fire extinguisher which can be installed at a minimum cost.
A further object of my invention is to provide a fire extinguisher which caused to automatically distribute a fire cXtinguisher fluid over a relatively large area when the fluid within the extinguisher forces open a valve or closure under the influence of heat.
Other and further objects and advantages will be in part described and in part do vious as the specification is proceeded with.
In the drawings wherein l have illustrated a preferred embodiment of my invention the single figure is longitudinal sectional view of the invention.
Refe ring to the drawings the numeral 1 designates a liquid tight and air tight nietallic container of any suitable shape, preferably cylindrical and preferably formed with a conical shaped bottom 2. The container 1, which is adapted to hold a highly volatile lire extinguishing fluid is adapted to be detachably bolted to the ceiling of a buildinn" by means of brackets 3.
Bolted to the lower end of the container 1 is a cap plate 4 apertured as at 5 to receive the tapered or conical portion 6 of a valve or closure 7. The valve 7 is tapered as shown, to snugly seat against the walls of the opening 5 and is provided'with a shoulder or flange 8 adapted to seat a cork washer or other packing 9 the upper face of which bears against the cap plate 4: to insure a liquidand air tight joint between these parts. The valve 7 is normally held in closed position by means of a frangible plate 10 of glass or the like hinged as at 39 to a lug 11 integrally formed on and depending from. the cap plate 4:. This frangible plate 10 is normally held in the position illustrated in the drawings by means of a preferably fusible link 12 looped at its upper and lower ends respectively over an extension 13 formed on the cap plate l and Specification of Letters Patent.

the free edge 14 of the hinged plate 10, the latter being thus held in tight engagement with the protuberance or fulcrum 15 formed on said valve 11. It will be noted that the protuberance 15 has a knife edge, the purpose of which will be presently described.
A hollow perforated liquid distributer 16 is mounted within the container l'by means of a stem 17, slidably guided in a spider 18 in turn bolted to the inner face of the con- The distributer is normally spring pressed againstithe inner face of valve 7 by a coil spring 20 engaging at opposite ends the spider 18 and distributer 16 as will be readily apparentfrom an inspection of the drawing.
In practice a highly volatile liquid which will not corrode metal or injure fabrics and the lilre and which is adapted to give off a heavier than air gas when exposed to air, is placed in the container 1, and the latter is then attached to the ceiling;- of building. it will be understood that the number of containers to be employed will be regulated according to the number of cubic feet of space to be protected, the capacity of the container and the fire extinguishing qualities of the liquid employed.
.vVhen a fire occurs in a room or building equipped with my invention the rise in temperature caused by a fire quickly expands the liquid in. the container 1, thereby causing the valve 7 to be forced outwardly against the frangible plate 10. The knife edge of the protuberance 15 will cause the plate 10 to break when the pressure in the container reaches a predetermined degree (it being understood that the plate 10 can be made of any desired strength) thus permitting the valve 7 to be forced outwardly from the opening 5. Simultaneously with the opening of the valve 7 the distributor is forced outwardly through the opening 5 until this movement is arrested by the flange coming in contact with the cap plate 4. Preferably a cork or other packing washer 22 effects a tight joint between said flange and cap plate. The liquid fire extinguishing medium within the container will now be forced under its own weight outwardly through the perforations 23 in a manner readily understood. The ejection of the fire extinguishing liquid is. also facilitated by virtue of the pressure generated within the container by the action of the heat from the conflagration and the liquid will as a result be sprayed over a considerable area, a
Any suitable means (not shown) may be provided for refilling the containers, but the latter will preferably be detached and shipped to the manufacturer forthis pur pose.
-- l/Vhere the link 12 is of fusible material 7 the operation of the extinguisher will be doubly sure. However, I do not depend upon the fusibility of the link 12 to release a container for fire extin uishin li uid said e g a container having an opening in its bottom wall, a valve for said opening, and a member of readily frangible material normally bearmg against said valve to hold the same in said opening, said member being adapted to break and release said valve when the liquid in said container exerts a predetermined pressure.
