i FIRE-EXTINGUISHER.
Application led May 16, 1916, Serial No. 97,814. Renewed April A To all whom t may concern:
using liquid lire ext' vwhich it appertains In the use ofhand l ing two or more chenucalswliichwhen the deviceis to be used are combined. to form a foam for extinguishing quantities of chemicals carbonio acid gas purposes the entire used to form such foanimust be employed.
This frequently causes unnecessary waste and requires the replenishing of the extinguisher after eve use. It is one of the objects of my inventlon to provide. a simple and efficient lire4 extinguisher wherein the chemicals which are to be combined may be separately stored until needed, and torender A .unnecessary the refillingof the extinguisher is a vertical sectional view o Va recess 8, which is after each use, improved means being employed to regulate the use of only. so' mucho of the lchemical compounds as maybe lrequired, the remaining portions being left un-' disturbed and ready for further use. A further object of the invention is t'o provide improved means for readily combining Iand mixing the uids to create tinguishing foam. In the accompanying drawin the' required 'exmy extinguisher. Fig. 2 isa detail perspective. F ig. 3 is a cross sectional View 'n line 3 3,
Fig. l.
Referrin to the drawings, the extinguisher is s own in theform of a container comprising two semi-cylindrical tanks, 1 and designed to be secured unitary structure, their Hat `:faces being bra-Zed or soldered to each other. -Each of such faces is provided with co-extensive-with the length of the container, such recesses form- Figure 1 Specication-of Letters Patent.
following to be a full,
- the solutions in the 2s, 1919, serial No. 293,558.
.ing a mix' chamber 4. The upper and lower ends of the tanks and the mixing chamber are closed b heads 5 and 6 respectively, the lower lhead7 6 being provided with a centrally disposed opening. 7 into which a discharge nozzle 8 is ldesigned to be fitted.
Dependin from the head 5 and extending into the tan s 1 and 2, respectively, are tubes or pipes A9 and 10. within a short distance' of' the bottom of the containers.
ySimilar tubes or pipes 12 and Patented June 10,1919.
These tubes .extend to i 13 are fitted in the head 5, and extend wellV down into the mixing chamber-Af. 'These several tubes are the media through which two tanks are introduced into the-mixing chamber where such solutions combine to form the. extinguishin gas. Arranged centrally of the'head'5, an with its up er end secured thereto, is an air pump cylin er 14, such cylinder occupying the upper portion of the mixing chamber and beingv provided with the usual piston 15 and piston rod 16, the latter being connected to an operating handle 17. lAir for .the pump is supplied through a bore 18 in .the handle.-
y the. other end of The lower end of the Vpump cylinder forms a support for one end of a discharge pipe 20, the pipe bein secured to the discharge nozzle,'thus hol in the apparatus together. At its upper enigl the d1schargepipe 20 is provided with a series of openings 21 through ing foam escapes to Super-imposedl onvalve disk 23 by means of which communication is established between-the solution tanks and the mixing chamb the air pump and the valve is provided with mer constitutin tube 9 ofthe so of the mixing forms a like communication between the tube 10 of solution tank 2 and the tube 13 of the mixing chamber. A second series of ports 28 and 29 establishes an air passage from the pump cylinder 'to the respective solution the discharge nozzle.
ports 25, 26, the forthe passageway between the ution tank 1 and the tube 12 tanks through openings 30 and 31, 'respec-- which the extinguish-- the head 54 is a rotatablel chamber, while the port 26 y alsy i.
er as well asbetween j I solution tanks. The
whichprevent the escape of the compressed air when the'pump piston is parta-king of its return stroke.V
The disk valve is held to the head 5 by means of a clamping ring 33 such ring also forming a lock to preve-nt operation of the device except when the pump handle is turned so as to register with cut-outs 34 in the ring. The. base of the handle is seated in a recess in the valve, such connection between the handle and valve beingl the means by which the latter is turned on the head 5. The valve is provided with stops 3G to regulate its turning movement.
1n the use of my lire extinguisher l prefer to employ two solutions, one an acid solution which is preferably of aluminum sulfate,
'such solution being confined in one tank, and
the other a solution of bicarbonate of soda, to which is added a foam making substance, which lat-ter may be glue-7 glucose, soap bark7 wood extract, or any substance which will make foam and retain the carbonio acid gas liberated by the reaction between the acid and alkaline solutions. The solution of the bicarbonate of soda with its foam making content. is confined in the second solution tank 2.
lVhen it is desired to mix these two solutions so as to form a tire extinguishing coinpound the valve 23 is turned by the handle 17 so that the ports of the valve will establish communication between the respective tubes of the solution tanks and the mixing chamber as well as between the openings in the solution chambers and the air pump. The handle being then in line with the cut-'outs 34, the pump piston is reciprocated forcing air into the solution tanks to displace the solutions which find egress through the respective tubes 9 and l() into the mixing chamber by way of the tubes l2 and 13. Astlie respective solutions are admixed, a .foam is produced within the mixing chamber consisting of millions of minute bubbles of pin-head size, these bubbles containing the carbonio' acid gas. Such foam is discharged through the tube 20 and the discharge nozzle 8. It is readily apparL ent that after a suliicient quantity ot team has been formed, the valve may be quickly turned to close the intel-communicating passageways, thus shutting off further supply ofthe solutions to the mixing` chamber. Thus it will be seen that by this means a large saving is effected, it beingr unnecessary to empty the tank upon every use of the extinguisher. The solutions are mixed in the quantities desired, and after the device has been once used it is only necessary to turn the valve leaving it in conditio'n for further immediate or later use.
