FIRE-FIGHTING DEVICE.

Application filedgAugust 12, 1922. Sera1-No. 581,554.

This invention relates to fire fighting devices of the portable type, and it is the primary object of the invention to provide a container for the storage of a hose arranged with a nozzle and with means for quick connection with a source of liquid supply, such as a water faucet and the container having a removable closure at the end to provide a closed receptacle for the hose whereby access may he had to the hose for connection with a source of liquid supply without removing the hose from the container, and the hose arranged in the container whereby it is adapted to be paid out from the container as one end of the hose is withdrawn therefrom, and to so arrange the hose and container that one may have rotative movement relative tothe other to prevent kinking of the hose as it is paid out from the container. f Other objects and advantages will herein-V after appear.

Similar characters of reference designate like parts throughout the different views of the drawings.

As is well known one ef the most efficient lire annihilators is'water but that it is :not always readily, accessible for distribution at the source of a confiagration. In order to therein in solution and also containing anv acid therein in separated condition from the water and soda solution, which combined with the soda in solution will react and evolve va gas pressure, such as carbonic acid gas which places the water in vthe reservoir under pressure in the container and forcibly ejects the same therefrom, thedevice .usually being suspended from a bracket.` To utilize the device it is removed from its support and manipulated' to cause the acid to mit; with the soda in solution whenthe water discharged therefrom is directed to the fire by a hose connected to the outlet of the reservoir. It is a primary object of the present invention to provide a` substitute for the above described type of iireeXt-inguisher whereby a fire annihilator, which may consist of water or other liquid, or another fire anni? hilator may he discharged by or with the water, at the source of the fire.

For this purpose I provide a container 12, preferably of .cylindrical form, having a removable closure 13 at the end and a hose 14 to he stored within said container', said hose being arranged with av coupling, shown in a general. way at C, for quick connection to a source of liquid supply, such as a water faucet, as shown at 15 (Figure (i), and a nozzle ,which may be connected directly to the hose.

as shown at 16 in Figure 5. The device arranged. above described is a unitarystructure, the hose being contain ed within the container which maybe supported upon a shelf or suspended from a bracket engaging a handle 16. In case of fire, the device is removed from its support and the cover 13 removed when the coupling C` is readily accessible for connection to a faucet without first removing the hose from the container and the water may be immediately turned on. The hose is coiled within the container, as shown. wherevby as the hose is connected to the faucet and an endof the hose withdrawn. the hose will be zle orilice 38 the plug has a right angled port 49 opening axially through the inne-r end ot the plug valve and through the lateral wall to be placed in communication with the portion 43 of the nozzle orifice 38.

rlhe respective ports are arranged in t-he nozzle and in the valve plug so that in one position ol said valve the port 47 will be in communication with the portion 42 oi the nozzle orifice 37 and the port 48 in communication with the port 45 as shown in Figure 4, thereby connecting the hose with the nozzle orifice 37 to discharge the liquid through the hose from the source of liquid supply directly to the atmosphere to be ut-ilized to extinguish the lire. In this position of the valve the liquid in the receptacle will be shut off irom the valve chamber through port 46 and from the nozzle orifice 38 through port 49.

To discharge the material from the receptacle through the nozzle orifice 38 by the liquid passing' through the hose from the source ot supply the valve plug is adjusted so that the valve port 47 is in register with the

ports

45, 46 thereby connecting` the hose with the chamber, as shown in Figures l and 2. ln this position ot the valve plug the port 49 will be in register with the portion 43 of the nozzle orifice 38 and the. nozzle orilice 37 will be shut oft from the valve chamber. The valve plug is also adjustable to place the

ports

47, 49 out of register with the port 46 and the

nozzle orilices

37, 38 thereby shutting oit both the hose and the receptacle from the nozzle orifices.

lThe plug 41 is rotatably mounted in the valve chamber of the nozzle by a screw 5() passing through an opening 51 in the nozzle between the nozzle orifices and threaded into the end of the plug with a washer 52 interposed between the screw head and the nozzle.

To manipulate the valve a tubular member 53 is secured axially in the valve plug in communication with the port 49 andy has a lateral port 54 to connect the tube und port 49 with the receptacle 35, the outer end ot the tube 53 being closed and extending through a stuffing box 55 with an operating handle 56 connected thereto at the exterior ot' the receptacle. The end of the receptacle has a removable closure 57 with a filler opening having a closure 58.

To connect the nozzle orilice 38 with the material in that portion ot the receptacle 35 which is lowermost, the specific gravity oi the material therein, carbon tetrachloride, being `greater than that oi" the expelling material, water, entering therein through the hose, inlet means is connected to the tubular member 53 in communication with the port 49 to position an inlet thereto by gravity in the lowerinost portion of the receptacle 35 in all positions thereof. This inlet means comprises a tube 59 extending longitudinally oit the receptacle with opposite ends open to the receptacle, said tube being mounted for rotative movement about the axis of the receptacle and in communication with the tubular member 53, by a sleeve 60 to which the tube 59 is connected by a tube 6l and to position the tube 59 at the side of the receptacle, The sleeve may be directly mounted upon the tubular member 53 in communication therewith, but as shown it is mounted upon a tube 62 secured at one end in the valve plug concentric with the tubular member 53 and in spaced relation thereto, the opposite end of the tube 62 being rotatably mounted in the stuffing box 55. This tube 62 has a port 63 to connect the sleeve and thereby the inlet means to the tubular member 53. The sleeve 60 has a portion between the ends thereof in spaced relation to the tube 62 whereby the inlet means is at all times in communication with the tube port 63, and the sleeve is supported on the tube 62 for rotative movement between the stuffing box 55 and a collar 64 lixed to the tube with

suitable washers

65, 66 interposed between the same and the ends of the sleeve.

To shut oit the end of the inlet tube 59 which is uppermost from the receptacle and open the inlet end which is lowermost thereto, gravity valve .mechanism is provided, shown as comprising a pair of balls 67, 68 to cooperate with valve seats arranged at op.

posite ends of the tube and connected by a rod 69 of such length so that when one valve is seated the other is unseated and whereby the valves are operable in unison.

ln the use of the device last described the closure 13 is removed and the hose coupling C connected to a source oi' liquid supply, such as a vater l'aucet, and the valve4l adjusted by the handle 56 to discharge the liquid from i the source ot supply direct upon a lire, or to cause said liquid to enter the receptacle 35 to discharge the material therefrom, and by removing the container l2 from the hose connection f'iththe liquid supply to the place oi the tire the hose will be paid out from the container, and this may be during the discharge of the liquid from the nozzle due to the arrangement of the storing oi' the hose within the container.

While I have described and illustrated the receptacle 35 and hose as being of a unitary structure with the container 12 in which the hose is to be stored and thereby providing` a compact arrangelnent otlire ighting device, it will be obvious that the receptacle 35 may be conn cted in the line et discharge ot the hose and utilized independent oit the container and come within the scope vott my invention. Y

As stated the hose is arranged with a coupling for quick connection to a source of liquid supply. As shown in Figures 5, 6 and 7, this coupling comprises a pair et members 67', 68 having a slip joint connection, the one member o8 being,Y arranged at the outer end tor conneetirni to a faucet, and is preferably permanentlv connected thereto as by internal Screw threads tor connection to a threaded faucet in com non shown at G9. rEhe member 6? is Jfor connection to a hose and has op i j ringiere mounted at one end at Il et. o threaded portion 73 W L iY 'ce ende bent inwardly and tensioned to normally Spring; laterally, .aid bent ende oeing adapted to engage an annular' receas '7e in the foiufi member GS and locked therein by c, thun i nut To mounted on a threaded pm'tion oilv e ie coupling member 67.

ln the oeupling Shown in Figures l and 8 the coupling nnmbe.' Si" han' pivotally mounted thereon a lvoue Shaped lever 7G and han nivo-tally connected thereto a yoke Shaped member 7i" 'te be brought inte and out o't operative roiatioi' with the annular receso M- oit the member e8 by movement et the lever 76 to loch the compiling mcffmliiere together.
