1 in any suitable manner and horizontally disposed is a tank Bof suiiicient size to hold a large volume of liquid. This tank ex? tends transversely of the frame and on the headendis provided with suitablecontrolling valve mechanism and gas supply mech anism which will be described.

The tank 3 is provided with a suitable bottom 4.- carrying a bearing 5 supporting an agitator shaft 6 provided with agitators 7 having diametrically disposed blades. There `are three agitators, and they are spaced throughout the tank and are so ai ranged that they will thoroughly agitate thej liquidtherein; The mechanism for supporting the'forward or head end rof the shaft will be described later.

. The tank 3 is preferably lined with sheet copper 8 on all sides and the bottom and the headend is provided with a suitable opening 9 extending through the4 steel tank land the lining. In this opening is mounted a suitable cylindrical connection r10 having a flangeA 11v conforming to the interior of the head and provided with openings 12. This connection 10 and the flangel 11 are held in place by a suitable ring 13 threaded into the lcylindrical portion of the connection. Vhen .the partsare drawn up tight by the ring 18, the interior of the tank is then iooded with solderso as to form a solder joint 141, as. shown in'Fig. 4. This solder extends Afrom the central ridge 15 out to meet the head as shown vin this figure and the solder passes down through the openings 12 and irmly'secures the parts in place, thus avoiding leakage., The object of the openings 12 isto provide round cross sections ofy solder connecting thev accumulated solder 14, and the solder` which passes'between the lining .and the flange.y In this way the connection 10-is held against rota-v tion. Threaded on to they connection 10 is a head 16. A suitable packing 17 is arranged between this head and the end of` the connection 10 to prevent leakage.

The head-16 is provided with three internal chambers 18, 19 and 20. The lirst chamber 18 is connected by a suitable opening 21 on .the inside of the. head with a pipe 22 eX- tending into the tan-k and down toward the bottom as shown. This pipe forms the liquid Ainlet and discharge from the tank. This chamber 18 is also provided with a radially; Quepasa@ Qpeniag as foul-sida.. or uit tank, and this opening is connected by a nipple 24pr to a T-shapedY Valve25 which is provided With'a valve seat V26' as shown in Fig. 5. This valve seat has coperatingwi'th it a valve 27 manipulated by the. usual.. Valve mechanism which needs nodescription. 'The Y valve seats, in the, bottom portion of .thefT and does notinterfere in any way, as shown in Fig. 5, with the passage et liquid:` above the valve. This Valve 27, the valve seat and the pipe24 serve as al main supply or the tank' in initially' fillingy the same, and also; to' allow" a stream.- to Vhow from pipe() directly to the hose connection 4:5" for quenching theL fire and toy simultaneously divert a portionof? thel main supply streaml into the tank .for filling the same. @neside lolitlflel 'l ofV this valve i's-l connected to a pi`pe128 leading to a valve 429i in turn connected to a pipev 30- mount'edl inea support 3h securedZ tothe head and' terminating* at its lowerl end in a suitable hose connection 32; This hose connection is of' the usuali size forreceivingy fire hoseand itmay also receivel al reduced hose connection 3B'- asl` shown.

Connected to the reducing valve 52 is a pipe 57 leading through -a heater casing 58" through a packing'5'9 within the casing and forming a part of a'heater coil 60 Wound upon theexhaust pipe 61 of the engine of The pipe 62 leading fromv this coil connects directly with the Valve meohanism' of the gas container 64: which isf of ordina-ny construction and is a commercial product.

From Vthe foregoing, it'` will be -seenthat thechamber I'Sltorms awaterreceiving-and water discharge chamber; that the cham.-

In manipulating theentirc mechanism, assuming that the tank iszempty of all liquid', and further' assuming that-the gas' container is full of'gas, thevvalve 35Ay is closed and.- the valves 27 and 29v are open, thus permitting wat-er from the main tourenterthrough these.

valli'fes into the` chamber 1'8 and.' thence through the .pipe 22 to. theibottom. of they tank. As soon as water overows through theA pipe- 38, the chamber 19, and` the pipe.` 42', the operator knowsf that the' tank is filled, the valve'- ll'having been previouslyopened.` The` operator then closes the 'valvesslh 27: and.E 29, opensthe-Ivalye from the=gas= con? twiner, seeingjto it thatfthe valve 56 is closed and that the valve 5101 iSv-open'. TheLgasi'sthen admitted. to the tank through the pipe 4-9 into the chamber 2O through'. the pipe 48 into: the water. In: the meantime the:l nut 6Sifis infthefposition. shown. in Fig. 4L, .and the operator rotates the agitator shaft 6,4 thusagitating the Water andi causinga: rapids formation ofthe solution of Coz'and water. Y

imams sumes about two minutes and when the gas discharge from the container 64 is closed, the machine is ready for operation, and if immediate use is necessary, the operator opens the valves 27 and 35, permitting the gasilied water to discharge through the discharge service hose upon the iire, the valve 29 being closed as above stated. If a second filling of the tank is necessary in service, the operator leaves the valve 27 open, discharges the gas from the tank through the connection 41, opens the valve 29 to suppl water to the discharge hose and divert a su cient quantity therefrom under the valve 27 to ll the tank. This diversion takes place without any appreciable variation in the stream of the service discharge hose, and takes a very short period of time. When this has been accomplished the operator closes the valve 27 without interfering with the supply of water from the hydrant to the re and completes the operations already described in the charging of the tank with gas. Vhen the water is completely charged, the valve 29 is closed and the valve 27 open, then gasiied water is supplied to the fire.

The apparatus also permits the discharge of free gas to the fire, and this is accomplished by closing the valve 27 or the valve 35 turning the three-way cock 43 and opening the valve 41 to permit a iiow oil gas from the upper part of the tank to the pipe 44 from whence it will pass to the cross connection 36 and out through the service hose connection 45, the cap 46 being in place.

I-Iaving described my invention, I claim l. In fire extinguishing apparatus, a tank horizontally disposed, a head at one end comprising a water inlet and discharge chamber, an overflow and gas outlet chamber, and a gas inlet chamber, a discharge connection leading from the water inlet and discharge chamber, a pipe leading from said chamber into the tank near the bottom thereof, a connection leading from the overliow and gas discharge chamber, a pipe leading from this chamber to a point near the top of the tank, a connection leading from the gas inlet chamber to the outside of the head, a pipe from the same chamber for discharging its gas downward into the tank, and means for supplying gas to the gas connection.
