FIRE EXTINGUISHER 001". 4, 3 Sheets-Sheet 3 INVENTOR. 7EQ Q /e U. Mouaer Arro/e/vgy Patented Mar. 23, 1954 UNITED STATES ?ATENT OFFICE This invention relates to a fire extinguisher, and more particularly to a fire extinguisher that is actuated by heat or flames of a conflagration.

The object of the invention is to provide a fire extinguisher that includes a mechanism that is actuated upon the outbreak of a fire or confiagration whereby water, or chemicals will be discharged onto the fire to extinguish the fire, the fire extinguisher of the present invention further including an alarm that is actuated when a fire occurs so that persons will be warned of the fire.

Another object of the invention is to provide a fire extinguisher that includes a means for simultaneously extinguishing the fire and sounding an alarm whereby the fire will be automatically extinguished and sleepers or other persons will be notified to thereby provide a fire extinguisher which has double safety features.

Still another object of the invention is to provide a fire extinguisher which will automatically extinguish a fire, the extinguisher of the present invention adapted to be placed in any locality where there is danger of a fire breaking out, the device of the present invention being small and compact and easily refilled and reset.

A further object of the invention is to provide a fire extinguisher which is extremely simple and inexpensive to manufacture.

-- Other objects and advantages will be apparent during the course of the following description.

In the accompanying drawings, forming a part of this application, and in which like numerals are used to designate like parts throughout the same:

Figure 1 is a side elevational view of a fire ex- Figure 3 is a sectional view taken on the line 3-3 of Figure 2;

Figure 4 is a sectional view taken on the line 4-4 of Figure 2;

Figure 5 i a sectional view taken on the line 5-5 of Figure 2;

Figure 6 is a perspective view of the chemical holding container;

Figure 7 is a plan view of the gasket;

Figure 8 is a plan view of the flammable connector; and

Figure 9 is a perspective view of the flammable connector.

Referring in detail to the drawings, the numeral 23 designates a suitable supporting structure such as a wall, and secured to the supporting structure 20, Figure 2, is a frame 2! which may be fabricated of metal. The frame 2| includes a plurality of spaced parallel legs 22 which arethereto is a plurality of end bars 25 and cross pieces 26. A housing 2! is supported on the frame 2 l, and the housing 21 includes an annular side wall 22% and an end wall 29. Arranged within the housing 2! is a spacer block or ring 32, and extending from the ring 32 is a bracket 3|. A bolt 33 serves to connect a dome-shaped bell 34 to the bracket 3! and, as later described in this application, the bell M will be sounded upon outbreak of a fire. A plurality of hammers are adapted to be moved into and out of engagement with the inner surface of the bell 34 for sounding the latter.

Extending into the housing 2! is a shaft 35 which is provided with a square portion 33 for a purpose to be later described. A first gear 31 is mounted on the square portion 36, and the gear 31 meshes with an intermediate gear 38v that is rotatably mounted on a pin 39. The gear 38 is arranged in meshing engagement with a gear til, and the gear M is connected to a shaft or pin 4!, the pin 4! being secured to a support member 42. The plurality of hammers 30 are supported by or mounted on the member 42. An arm 43 has one end connected to the square portion 36 of the shaft 35 while the other end of the arm 43 is connected to a bushing 44 through which extends the pin 4|.

A means is provided for selectively causing rotation of the shaft 35 when a fire occurs. This means comprises a spring member 48 which is positioned within the housing 21 and wound about the shaft 35. The inner portion of the spring member 45 is secured to the shaft 35 by a suitable pin 45, while the outer end of the spring 46 is secured to one of the legs 22 by a screw 41.-

Arranged on the outer end of the shaft 35 is a sleeve 49, and mounted on the sleeve 49 is a tank 48. The sleeve 49 is provided on its rear or inner end with a ratchet or cam surface 50 which is adapted to engage a pin 5| that extends.

through the shaft 35. Suitable nuts 52 and 53 are arranged on each end of the shaft 35 for maintaining the parts in their proper assembled relation.

A means is provided for preventing the rotation f the tank 48 until heat from a fire actuates the mechanism. This means comprises a strip of flammable material 54 which may be made of any suitable material such as Celluloid. One end of the Celluloid strip 54 is connected to a bolt and nut assembly 55 that extends from the housing 21, while the other end of the strip 54 is connected to a bolt and nut assembly 56 that extends from the tank 48. When the heat from the fire is ,sufficient to burn ormelt the Celluloid strip .54, the spring member 4Bwill cause rotation of the shaft 35 and this in turn will cause rotation of the tank 48 whereby the bell 34 will be sounded. At the same time, the tank 48 will be rotated so thatlthe, material contained therein Will be sprayed onto the fire to extinguish the latter. The strip 54 is provided with suitable holes 51, Figural), whereby the bolts 55 and 55 can readily be extended therethrough.

The tank 48 is adapted to hold any desired liquid such as Water or other fluid and this liquid is indicated by the letter L. Supported by the tank i48i'isarcontainer 58*which is provided with cut-outs 59 whereby the dry chemical C'a-rranged inrthe=container 58-may become intermixed with the=liquidL when the tank 48 is being rotated. Extending across the top of the container 58 is anrarcuate-lid 6!! which is provided with a plurality of spaced openings 6| whereby suitable bolts fizii-canbeextended therethrough. A gasket 63 is interposed between the lid 69 and the annular wall 6610f 'thetank 48 for insuring that ther is afiluidtight seal. The gasket 83 is provided with aclarge cut-out 64, Figure '7, whereby the major portionsof the container 58 can be projected there through. Suitable openings E5'are provided for registering with the openings 6! whereby the boltsfil can extend through the gasket 63. The annular wall 66 of the tank 48 is provided with a pluralityof spaced holes or openings 61 whereby the'material from the tank 48 will be-discharged through'the openings 6'! and onto the-fire to be extinguished.

In use, the tank 58'is filled with a suitable fire extinguishing chemical C and the tank orcontainer'58 is seated in the large tank 48 which is also filled with a fire extinguishing fluid L. Initially-the tank 48 is manually rotated to wind up the spring member 46. Then, in the event a fire or conflagration occurs, the flammable strip 54' which has been previously positioned as shown in Figure 2, burns up so that the spring'member 45- will cause rotation of the shaft 35. As the shaft rotates, the tank 48 will be rotated due to the pin 51' and' ratchet 50. This will cause the-liquid L andchemical'C 'tobe intermixed due-to th provision of the cut-outs 59 and this mixture offire: extinguishing material will bedischarged through the opening 61 onto the fire to thereby extinguish, the fire; Simultaneously, the hammers'30 will be moved into and out of engagementiwiththe bell34 so that thebell 34 will be sounded whereby; neighborsgorother persons will be'warned of the fire.

From the foregoing, it is apparentthat a fire extinguisher has been provided which will automatically extinguish a fire, at the outset. The extinguisher may be placed wherever there is dangerxof a fire breakingout andit can be made small; and compact and will not jam, or failLto work. Also,the fire extinguisher of the present-v inventionissimple and canbe fastened toawalli or-appliance. The, bell 3.4, when soundedtuwillf. awaken sleeping persons who might be victims; andmwill also attract nearby. neighbors; After the spring 46 has become unwound, the shaft 35 will quit rotating, but the tank 48 will continue to rotate due to the pin 5| and ratchet 50. Thus, the contents will be continually sprayed onto the fire to be extinguished. The m chanism is first wound and set and then filled with a suitable fire extinguishing liquid. Certain of the outlet openings are designated by the numeral 61, and the openings 61' may be arranged angularly as desired.
