m may concern:

Known that E, Jossrn O. BANNING, citizen of the United States, residing-at New York, in the county ohlflew York and State of New York, have invented certain new and useful Improvements in Fire-Extinguishers; and I do declare the following to he a full, clear, and exact descriptionof the invention, such as will enable others skilled in the art to which it eppertains to make and use the same.

This invention relates to new and useful improvements in fire extinguishers and has for itsohject to provide a simple and desirable device'of this character wherein compressed. air is used to expel the extinguishing iiiilf d wherein suitable valve connections ere e; ployed for controlling the passage of the-pressure fluid from a storage receptacle in the main casing to the interior of said casing.

llith this and other objects in View, the invention consistsol' certain novel features ol co truction, combination, and arrangement of parts, as will he more fully described ly pointed out in the appended claims.

in the accompanying drawings, Fi ure 1 is side elevation of the fire extinguisher em- 'eorlying the present improvements; Fig. 2 is :1 central longitudinal section thereof on on c scale Fig. 3 is a central vertical seeof the pressure controlling mecns on an e L mile; and Fig. 4 is a horizontal scction, ahen on line 4-4 of Fig. 3.

in the embodiment illustrated, which is for illustrative purposes only and therefore not drawn to scale, numeral 1. indicates the main seeing of the fire extin uisher in which is placed the extinguishing luid and 2 e suitable cylinder for holding the compressed-air or other agent i'oiflexpelling the extinguishing said c der being arranged centrally in the casing with its ring in a centrally disposed cas from the bottom of tie main teriorly threaded, as at 4, to receive the in teriorly threaded rim 5 ol' a; suitable solid cylinder cap 6 provided with a central valve opening 7 which is normally closed by spring pressed valve 8 having reduced portion or stem 9 at its lower end to work through a corresponding guide opening in an approximate U-shaped hearing or frame 10 and at its upper end with a guide stem 11 I end with a suitable gasket or packing ring 18 to seat Within an annular flange 19 produced at the extreme upper end of the main casing and thereby seal the upper end of the casing a ainst the escape ol any compressed air. T 1e cap is provided with a central threaded opening 20 and with a centrally disposed exteriorly threaded tubular upstanding stem 2] at its top surface around said opening upon which is screwed an intcriorly threaded cap 22 provided in its top with a central opening 28.

The numeral 24 indicates a cap which is arranged with its rim L lilting in. the stem 21 and its annular flange 26 seating upon the upper edge of said stem, the bore of said cap registering with'the opening 23 of the cap 22.

Numeral 27 indicates a valve operating device which comprises a stem having; a lower reduced cylindrical portion provided. intermediately of its ends with a thread 29 adapted for screwed engagement/with the threaded opening 26 of the ip i5, the lower end of the stem fitting in the upper end of the valve opening 7; of ".e esp 6. The stem of the valve operating also comprises an upper enlarged porti i the Wall of theepening of the cop Q lItherehy ,annular space 41 between.

sealing the upper end of the cap 15 against the passage of any air therefrom. The eX- l tinguisher is also provided with a suitable handle comprising a flat annular baseplate 31 which screws upon the top of the cap 15 and an annular ring 32 suitably connected wit the base plate and adapted to be grasped or engaged by the operator. The l casing is also provided with a suitable discharge or outlet pipe 33 which is arranged vertically within the same at one side of the l casing and extends to a point near the bottom thereof, the lower ,end of said pipe terminating in a mouth 34 and the upper end 35 thereof extending through one side of the casing to which isconnected a flexible hose connection 36 provided with a stop cock 37. In the operation of the device, the operator turns the valve operating device 27 by means of its handle 38 to cause the lower portion 28 thereof to engage and depress'the spring controlled valve 8 sul'liciently to permit the passage of the compressed air from the storage cylinder 2 through the valve opening 7 of the cap (5 into an annular chamber 35) formed by the interior of the rim of the cap 1:"). The compressed air then passes through a plu rality of right-angularlv formed ports 40 formed in the rim of said cap and communieating with the valve chamber 39 to the l the rim of the cap i and the upper end of the storage cylinder. This compressed air or other agent acting -1 upon the extinguishing 'Iluid forces the same into the lower end of the outer pipe 33 and through said pipe and the llexiblc hose connection in a continuous jet or stream until the valve operating device is unscrewed to permit the spring controlled valve 8 to again close the valve opening 7 in the cap (5. l From the foregoing description, taken in connection with the accompanying drawings,

operation of the in-veni tion will be readily understood without rcuiring a more extended explanation. Various changes in the form, proportions and the minor details of construction may be resorted to without departing from the principle or sacrificing an r of the advantages of this invention as de ned in the appended claims.

Having thus described and ascertained the nature of my invention, what I claim as new and desire to secure by Letters-Patent is:

1. In a lire extinguisher of the class described, thecombination with an outer casthe construction and ing, of a compressed air receptacle arranged therein, a cap provided with a spring controlled valve screwing over the upper end of the compressed air cylinder, a second cap screwing into the upper end of the casing, and a valve operating device screwing through the last mentioned cap and adapted to release or depress said valve.

2. In a fire extinguisher of the class devidcd with a plurality 'of being screwed upon the first scribed, thecombination with an outer casing, of a compressed air receptacle, arranged therein, a cap screwing over the up )er end of the air receptacle, a depending bearing frame attached to the bottom of said cap, a spring controlled valve arranged in said frame, a second cap screwing into the upper end of the casing and provided with outlet ports leadiig from the space between it and the first mentioned cap to the interior of the casing, and a valve operating device screwin into the second mentioned cap and adapi a to release said valve to permit the passage of the pressure fluid from the storage receptacle into the casing.

3. In a fire extinguisher of the class described, the combination with an outer casing, of a compressed. air receptacle arrange l centrally and vertically therein, a cap carrying a spring controlled valve screwing over the upper end of said receptacle, a/second cap screwing into the up er end of the'casing and upon the body of tie first mentioned cap, said last 1 cntioned cap having a rim proof right-angularly formed discharge ports leading to the inner surface of the rim, means for limiting the extent which the last mentioned cap is capable mentioned cap in order to provide a space between the same, and a valve operating into the second named cap and comprising a stem adapted to depress said valve to permit the passage of the compressed air in the compressed air receptacle to the space between the two caps out ot the discharge ports in the rim of the second named cap into the ini terior of the valve casing to cause the eX- pulsion of the extinguishing lluid.
