Fig.3 is a rear elevation of the extinguisher,
material, and containing a fire extinguishing liquid, such as carbon tetrachloride, and means for supporting the container in such a Way that it can be easily and quickly removed from its support and manipulated to v break the container andrelease the fire extinguishing liquid.
The frangible container is enclosed within a casing having a body portion, a top por-. tion and a bottom portion. hammer or plunger is slidably mounted in the; bottom portion and is adapted to be forcedinivardly by a blow thereon to break the, frangible, container and liberate the liquid contained" thereby. Means is also providedfor'siip porting the frangible container in sucha Way that it will not he accidentally broken but will be held against displacement inthe casing. The top portion of the casing is de tachably connecte-d to thebody portion in such a manner that it can be readily removed, thus facilitating the replacement-ofthe container after the extinguisher has been usedl',
Further details of the invention will ap pear from the followingdescription. I
In the particular form of the invention il lustrated the extinguisher is supported on a bracket consisting of an elongated 10 having its lower end 11 extending laterally to a position beneath a hammer hereinafter described. The upper endof the plate." is
folded back to form a lip 12.,
If desired, the bracket 2 can be supported by the loop formed at the. junction of the lip 12 and the main body portion of; these bracket 10., For instance, the lip may be ,placed over thebottom edge of a pocket in thefdoor of an automobile. In ruer, how! 1 ever, to v facilitate the attachment of the brackett'o a vertical Wall, countersunk openings 1 1 and 15 are formed in the body portion; of the bracket and in the lip, 12$" An opening 16 is also formed in the bracket in alinement with the. countersunk opening 14 to permit the passage of-a screw through '95 the opening let.
The fire extinguisher illustrated comprises an elongated tubular containerIQO- formed of frangible material, such as glass,
and having a depression 21 at the lowerend 10 thereof. The glass or material at the depression 21 is preferably thinner than the remaining portion of the wall to make it more frangible. I
In order to protect the frangible container from accidental breakage the container is housed in andcovered by a casing comprising a central-or body portion 25, a bottom 26 and. a cap or cover 27 which forms the top of the casing. i
The body portion '25 consists of a cylindri-- cal band or sleevehaving outturned flanges 30 and 31 tapered longitudinally with respect to each other, as shown in Fig. 3. The
body portion has a plurality of lugs or lips 32 struck .outfrom the material thereof and extending through the dome shaped bottom 26 of the casing. From the showing in Fig. 1 it will be noted that the lower peripheral portions 35 'of the container are so formed thatthey will rest on the portions 36 of the :dome shaped bottom 26. I I i I The cover or cap 27 which forms the top of the casing is provided with lugs 40 which are adapted to engage recesses or openings 41 formed along the upper edge of the body portion 25 and the cap is also provided with a laterally extending lug 42 which extends through a slot 43 formed in the back portion,
of the wall of the body portion 25. A spring 45 ispositioned within the cap 27 and presses against the upper end of the containerin order to prevent end wisemovement of the container in the casing and to hold the con the depressed portion 21 of thelower end of the'container. The portion 11 ofthe bracket extends beneath the lower end of the hammer shank a9 and prevents accidental engagement'ther'ewith; I
The casing and container is secured to the bracket byfmeans of resilient legs and 61 of a U-shaped spring 62; The spring is secured to the front face of the bracket 10 by means of flanges l 63 and lug sv 65 and 66 formed on the flanges and extending into engagement with. the spring; The upper ends of the legs 60 and 61-canslide beneath the lugs 66 to permit the legs which are bowed inwardly to be. forced outwardly. In order,-
to mount the casing and container on the bracket'the casing is positioned. as shown in Fig. ti with'the. legs 60 and 61 engaging between the outer surfac-e of theband 'or cen-' tral portion 25 of the casing and the flanges 37and 38 of the clamping plate-1'0. This can be accomplishedby forcing one of the legs laterally and snapping the rother leg into the position shown in Fig. 4 or by moving the container downwardly so that the tapered clamping plate will be positioned with In order to use the device shown in Fig. 2 the container is removed from the bracket by sliding it upwardly or merely by grasping it firmly and pulling it away from the bracket and then the shank 49 of the hammer is engaged against any suitable object and forced inwardly, breaking the" lower end of the frangible container. The bottom 27 of the casing has a plurality of perforations or openings .55 to permit, the fire extinguishing fluid to pass therethrough. I
In the form of the invention shown in Fig. 5 the hammer isnormally held'in retracted position spaced from the depressed portion 21 of the container by means. of a pin 56 which extends through the hammer shank a9 and beneath the lower end of the bushing '50. The pin 56 is preferably formed of fusible metal so that in case of fire the pin will melt,
thereby permitting the spring52, to force the hammer. upwardly into engagement with the container, causing the container to be broken and the fire-extinguishing lfluidto be released. The pin 56 may, if desired, have a cord 57 secured thereto and extending in a position in which it will be'accessible-so that the pin can be manually withdrawn, thus releasing the hammer.
As above stated, in order to use the extinits flanges behind the springslegs 60 and 61. I
guisher, itis merely necessary to grasp the casing and remove it from the bracket, whereupon the hammer can be forced in-v V wardlyto'break' the container and the fluid can be sprinkled or poured on the fire. Also,
as stated, with the device shown in Fig.5,
I incase of fire the pin 56 will melt,- thus automatically releasing. the fire extinguishing fluid.
erted against the cap 27 above the lugs 40 to release the lugs from thedepressions or open- In order to replace the containerlafter the I extinguisher has been used, pressure isex- 'ings 4:1 in the body portion 25. t The cap is I then swung about the lug 4:2 as a pivot, per
mitting the broken container to be removed -throughthe top of the'body portion 25fand a new container to be inserted in the "casing.
'After a new container, has been inserted the cover 27 is swung down again'and the lugstO will snap into the depressions or: opening-s41,
thus locking the coverinplace.
It will be apparent from the foregoing specificationlthata simple and practical fire extinguisher and support have been designed and that the container is so supported and held that it will not beaccidentally broken by jarringor chucking back and forth in the casing. Furthermore, the casing is so supported that it can'be readily and quickly removed from the supporting bracket and the extinguishing liquid can be released by tapping or striking a blow on the plunger.
Although certain specific embodiments of the invention have been particularly shown and described, it will be understood that the invention is capable of modification and that changes in the construction and in the arrangement of the various cooperating parts may be made without departing from the spirit or scope of the invention as expressed in the following claims.
What I claim is:
1. In combination, a casing comprising an elongated central portion, a perforated bottom and a removable top, a frangible container in the casing, a spring surrounding a and engaging the top of the container and disposed between the container and top of the casing for holding the container against end- Wise movement in the casing, and a plunger slidable in and extending through the perforated bottom of the casing for puncturing the container and releasing the fire extinguishing liquid therefrom.
(iii
2. In combination, a casing comprising an elongated central portion, a perforated bottom and a removable top, a frangible container in the casing, a spring surrounding and engaging the top of the. container and disposed between the container and top of thecasing for holding the container against endwise movement in the casing, and a plunger slidable'in and extending through the perforated bottom of the casing for puncturing the container and releasing the fire extinguishing liquid therefrom, said container having an indented lower end and said plunger extending into the indented portion thereof.
In witness whereof, I have hereunto set my hand this 20th day of January, 1928.
