accidental splashing of the solutions one into the other, or through the foam outlet, and

"consists in the provision of means for confining the solutions to their respective compartments and, more particularly, in the improved means to that end herein described and exemplified in the accompanying draw ings.

Fig. 7 is a horizontal section 011 line VII-VIE of Fig. 6,

Fig. 8 is a vertical section of an extinguisher having a manually operated form of the invention applied, and

Fig. 9 is a plan view of the extinguisher of Fig. 8, partly broken away to show a detail of the same.

The extinguishers illustrated include an outer container 1 and a removable, inner con tainer 2, constituting the solution compart ments. The neck casting 3 of the outer container serves as a mixing chamber from which the foam is discharged by way of outlet 1; an elbow 5 screwed into the outlet carries the usual hose 6 and nozzle 7 The outer container is closed by cap 8'.

The neck casting 8 has an integral flange 9 which serves to locate the inner container and also as a partition between the outer container and the mixing chamber, openings 10 in the flange providing for the passage of the solution from the outer container intothe mixing chamber.

bottom of container 1 serve to locate and grip i the inner container, which may be suitably formed for this purpose, to hold thesame against longitudinal movement when the extinguisher is inverted. The length of the inner container is such that when so held its upper end terminates flush with the neck flange so that a single stopple 12 seating on the flange serves to close the mouth of the inner container and also the outer container 360 outlets 10. By this means the solutions are confined totheir respective compartments and effectively prevented from splashing into each other or throughthe outlet. Upon inversion of the extinguisher, in this form, the C stopple falls away by gravity and so releases the solutions which thereupon flow into'the mixing chamber. The stopple may of course be manually controlled if desired.

In the form ofFig. 3, the inner container 2 rests in a cupped depression in the bottom of the outer container and its upper endextends up through the mixing chamberandis closed by a sealing disc 13, carried by cap 8. A ring of openings 14 comprises the outlet from the inner container into the mixing chamber. V

In this form the compartment outlets are closed by an annular stopple'which slides on The sleeve portion 15 mo the inner container. of the stopple normally closes openings 14: and the flange. portion 16 closes openings 10, as above. When the extinguisher is inverted, the stopple slides on the inner container tothe other end of the mixing chamber thereby 535 opening the respective compartment outlets and releasing the solutions. 7 V In Fig. 5 the upper end of the inner container is secured to and closed bya stopple 17 which seats on the neck flange and closes openings 10. Openings 18 in the inner container wall are normally closed by. sleeve 19 depending from flange 9; Upon inversion of the extinguisherthe innercontainer and stopple slide bodily towards the closure cap .95

8, bringing the container openings 18 into the mixing chamber and at the same time uncovering flange openings 10. y

, A slightly modified arrangement is shown in Fig. 6 inwhich the stopple is seeuredto 1 the inner container, as above, but is of annular form. serving only to close outlets 10. The closure of the inner container is effected by a loose stopple 20 carried on a seat member 21 located just below the container openings 18. In operation, the inner container and annular stopple slide toward cap 8, as above described, and stopple 20 falls away from its seat to permit the solution to flow from the inner container into the mixing chamber.

As above mentioned, both gravity and manually operated stopples are within the contemplation of the invention and, by way of illustration, Fig. 8 shows a further modified form embodying a manual control.

The neck flange 9 is recessed to receive a supporting ring 22 which is secured to the upper end of the inner container whereby the latter is suspended with its mouth approximately flush with flange 9. The solution compartments are closed by two stopple members which however are organized for operation as a unit. Stopple 23 engages a seat member 24 secured to the inner container and stopple 25, which is of cupped form, has a rim portion 26 which seats on the neck flange, these two stopples thus closing respectively the inner and outer containers. Both stopples are loosely mounted on the reduced end of stem 27 which extends up through a stuffing box in the closure cap 8 and terminates in a handle 28. A bayonet cap 29 is rigidly secured to the stem and its shoulders 30 co-operate with lugs 31 upstanding from the closure cap to prevent upward movement of the stem and handle until the latter is rotated one half-turn from the position shown. Spring 32 holds the shoulders and lugs in engagement. In this position of the handle shoulder 33 on the stem locks stopple 25 so that its rim 26 seals the outer container outlets 10 and a spring 34 inserted between the stopples urges stopple 23 into engagement with its seat on member 24. Thus locked, the extinguisher can be tipped, shaken or even inverted without fear of the solutions splashing into each other or through the outlet and in time of fire it is merely necessary to rotate and lift handle 28 when nut 35 will engage and lift stopple 23 and the latter in turn, through spring 34:, will lift stopplc 25, whereupon both solutions are free to flow into the mixing chamber when the extinguisher is inverted.

To facilitate the separation of stopple 23 from its seat in case it should be stuck and also to prevent the inner container from sliding into the mixing chamber when the extinguisher is inverted, I have shown a num ber of pins 36 screwed into the closure cap and passing freely through stopple 25. These pins terminate adjacent the supporting ring 22 and constitute a rigid stop against which the ring will strike if the inner C011- tainer'moves toward the closure cap.

In each of the above forms of the invention it will be apparent that I have provided a simple and inexpensive means for confining and thereby conserving the solutions. By reason of the concentric arrangement of the compartment outlets to the mixing chamber, the solutions are rapidly and thoroughly mixed. The provision of means for obstructing the flow of both solutions and releasing the same simultaneously results in the two solutions reaching the mixing chamber at about the same time, so that foam is produced from the beginning and the usual preliminary squirt of liquid is avoided.

Having now described my invention, I claim:
