- device for automatically extinguishing fire,

to the last named uses.

and more particularly for extinguishmg burning oil, gasolene or other fluid while simultaneously shutting off the supply of such fluid from the point of combustion.

My invention is conspicuously useful in preventing accidental conflagration on automobiles, in motor boats and in connection with gas and gasolcne en ines in general,

and accordingly I have erein described and illustrated a particular embodiment of the inventive idea which is' especially suited It is to be understood, however, that the invention may be employed for extinguishing fires however originating.

The invention is illustrated in a preferred form in the accompanying drawings, where- 1n- Figure 1 is a plan view of the device as attached to the rising manifold bf an ordinary gas engine, ,Fig. 2.is a median horizontal section of the same, Fig. 3 is an end elevation of the device, Fig; 4 is a sectional viewtaken on the plane 4-4 of Fig. 2, and Fig. 5 is a section on the plane of Fig. 2.

My invention, broadly stated, comprises the use in combination of means for supporting and separating two substances which, when mingled produce an extinguishing gas or fluid; a device for rendering the separating means inoperative, whereby these substances are allowed to mingle; and means normally restraining the device last mentioned, but adapted tQIiberate the same when affected by an'abnormally high temperature. The first named agency may be termed the separating suppprt. The second named device is broadly referred to as;

the mingling means and ,the last named element is called the restraining device.

In the preferred apparatus the separating support comprises two bottles 10 and 11, of

glass or other material easily shattered car-' ried ina suitable holder. In the form shown this holder comprises a cylinder 12,

suitably perforated in such a manner as to discharge its contents under suflicientpressure as hereafter'described.

Inorder to facilitate removal of the broken glass after operation of the device I prefer to provide a removable lining of'wire netting 13, within which the vessels 10 and 11 are placed. This netting also serves, to.

prevent the broken glass from closing the perforations in the cylinder and preventing escape of fluid.

The holder 12 is closed 'atits two ends by the caps 14 and 15 which are preferabl screwed onto the holder, 28 shown. 1 'pre fer to provide a lock for the outer cap 14, which consists of a spring-pressed pin 16 which moves within the hollow boss 17 and enters a suitable cavity 18 with which it registers when the cap 14 is screwed home, A cylindrical passage 19 constituting a gun barrel, pierces the cap 15., preferably .in'an eccentric position, and this passage com- 4 municates with an exterior enlargement intended to receive the removable breech block 20. As clearly shown in Fig. 5., this block is preferably held" in placerby a tapered pin 21, engaging both the block 20 and the surrounding portions of the cap 15. The breech block 20 is suitably pierced to receive a firing pin 22, and it may be provided with a handle 23. The block 20 also carries two cars 24 between which is pivoted a dog 25} on the pin 26. The upper end of the dog rests upon the base .of the-firing pin 22 and its-lower end 'exte'nds below the i'mder surface of the holder 12. v

., Within the barrel 19 there is laced a suitable bullet cartridge 27, which is discharged by a blow upon the firing pin. In order to provide means for delivering the necessary blow, the cap 15 carries a cylinder 28, closed at its ends by the screw caps 29 30, the

latter of which :is perforated, as shown. Within the cylinder 28 .the striker bar 31 is adapted to slide forward under the infiu 1 ence of the spring 32. This bar is guided .by the cap 29 and the piston 33. The car-' 'tridge, firing pin, dog and striker bar fdr'm the principal elements of the mingling .perature. Preferably this member is rendered inoperative by being destroyed by the 4 other suitable mixture) acid holder.

temperature in question, either wholly or part y. In claiming this member as one adapted to be destroyed by abnormally high temperature, I am to be understood as 1neluding partial destruction. Preferably I employ for this pu se a cord 34, by which term I intend to inc ude'a wire, for instance, of magnesium or other metal which is rapidly burned when exposed to fire.

I mtg also use thread or string impregnated wi salt r or associated with or formed of nitro-cellulose. Indeed any highl inflammable thread, cord or wire, wil answer. The cord 34 Is fastened at one end to the striker rod 31 and may then be laid or carried to any suitable position within the influence of the device where fire is liable to occur, the. outer end of said cord being made fast. In the form shown the cord ls'ca-rried through openings in' the cars 35, 36 and back to the ear 37. It is obviousthat,

the instant that the cord 34 feels the heatofa flame and is partly or wholly destroyed, the striker rod 31 is liberated, and, under the influence of the spring 32, it will deliver a blow upon the do 25 which causes the firing pin 22 to disc arge the cartridge 27. At once the holder is filled with a mixture of sodium bicarbonate and sulfuric acid (or whereby there is developed an immense volume of carbonic This gas is expelled, together with the liquid, through the perforationsin the holder, hnder the influence of its own expansion and the gases liberated from the cartridge. The expansive force of these gases is so great that an atmos ble of sup rting combustion 18 created for a long The apparatus. so .far described is suificient to act as a fire extinguisher for all purposes; but, where intended for use in connection with 3 devices using gasolene, I prefer to-associate with the elements so far described other mechanism adapted to act harmoniously with it to cut ofi the supply of gasolene or the like in case of fire.

In the particular device illustrated in the drawings, the holder 12 is fastened to the upright manifold 38, as by the clamp 39."

The ca-rbureter 40 is supplied with gasolene by a pipe 41 leading from the opening 42 in the cap 15, and the gasolene is led to the here incapaistance around the perforated the rod '45 is pivotally attached 'thcrcto.

The opposite end of the beam 47 hears upon the end of a pin 48, passing through the screw cap 49 and having at its lower end a piston 50.- A passage 51 leads from the barrel 19 directly under the piston 50. \Vhcn the cartridge is discharged the ressurc of explosion is transmitted through the passage 51 to the piston 50. The pin 48 is forcibly lifted, and acts, through the walking beam 47 to lower the valve rod 45. and shut ofl' the gasolene.

My invention is not limited to the use of a cartridge, and, where other meansare used for breaking down the separation between the active liquids, the pressure of the extinguishing giases may be relied upon to be transmitte through the passage 51 and close the valve as described.

Various changes may be made in my apparatus without departing from the scope of my claims, and I'do not limit myself to the details herein shown and described.
