GEORGE SCHROEDER, OF WASHINGTON.DISTRICT OF COLUMBIA.

FlRE-EXTINGUISHER.

Application filed June 14, 1904.

To all whom it may concern; Beit known that I, GEORGE G. Scrrnonnnn,

a citizen of the United States, residing at Washington, in the District of Columbia, have invented certain new and useful Improvements in Fire-Extinguishers, of which the following is a. speciii cation.

This invention relates generally to fire-extinguishers, but more particularly to that class known as automatic extinguishers in which carbonic-acid gas is utilized to exting-iriish a flame and prevent the spreading of The object of the invention is to provide an improved means for automatically mixing the gas elements and hberatmg the same into v outside atmosphere when the temperature of the roomin which the receptacle containing the gas reaches a certain degree ofheat.

Heretofore the only class of automatic fireextinguishers which have come into general use are those which employ thermostat to operate a cook or faucet to a ater-supply. As no means is provided to turn oil the water, it has been found that not infrequently as much damage results from the flow of water as from the fire. For this reason carbonicacid gas is a much more desirable agent than water, because the escaping gas an in no way deteriorate such goods as m ght be in the vicinity of the receptacle containing it.

The peculiar manner of accomplishing the desired result and the novel details of construction will be clearly brought out in the following description and illustrated by the accompanying drawings and defined in the appended claims.

In the drawings, Figure 1 represents a perspective view of an extinguisher constructed in accordance with my invention in its normalposition. Fig. 2 is a vertical longitudinal sectional view of the same. Fig. 3 is a front elevation of the receptacleinthc act of discharging the gaseous fumes. horizontal sectional view of the re eptacle cut on the line 4 4 of Fig. 2. Fig. 5 is a side elevation of a slight modification, and Fig. 6

is a longitudinal sectional view of the same.

Referring now to the drawings, 1 and 2 designate two downwardly-projecting supporting-bars secured to any suitable superimposed support at their upper ends and provided at their lower extremities with bearings 3 and 4.

5 designates a receptacle of any form, but preferably cylindrical and provided with Specification of Letters Patent.

Renewed June 27.1906. Serial No. 323,597.

trunnions 6 and 7 at points diametrically opl Fig. 4 is a Patented Sept. 4, 1906 posite and below the transverse center there- 'of to fit in the bearings 3 and 4, so that the tendency of the receptacle will be to tilt and discharge its contentsth-rou'gh the perforated discharge-nozzle 8 at the upper end thereof. However, such action is prevented by the band 9, carried by the bars 1 and 2. This band 9 encircles the receptacle 5, and the meeting ends thereof are soldered or secured together by some cementing agent fusible at a low temperature. The receptacle 5 is designed to contain the alkaline ingredients of the gas.

Immediately adjacent the opening nozzle 8 is ositioned a secondary receptacle 11, containing the acid ingredient, closed exce t for the perforated cap 12 at its outlet or nec r. This secondary rece )tacl'e is supported in a yoke 13, depending rom the inner end of the receptacle 5, and supports also a perforated disk 14,. located between the cap 12 and the nozzle heretofore referred to.

, It will be noticed that the matter or ii uid in the receptacle does not fill the receptac e 5, and, although the acid in the receptacle 11 is adapted to be spilled out thereof, the two liquids cannot commingle except when the receptacle 5 is inverted.

The band 9, which, is carried by the supports 1 and 2, encircles the receptacle 5 at a point above its transverse center, preferably near the u per end thereof, and in such a manner that t e same may be tilted slightly out go This will allow the ends of the band to spring 5 apart, and as the weight of the receptacle 5 is above the pivotal point thereof the same will become inverted, with the discharge ends of the respective receptacles at the lower ends. As the two fluids are thus forced out through. thenczzle 6 they will be retarded by the disk 14 long enough to permit and insure the commingling of the two elements, which will thus form acarbonic-surrounding atmosphere and destroy any fire which may be in the immediate vicinity.

As-the contents of the two receptacles will be proportionate to the volume of air in the room in which the device is located, it will readily be apparent that no deterioration to the contents of the room will result from an excess of gas.

ICC)

proximately vertical position to normally prevent the commingling of the respective elements. However, as soon as the receptacle 5 is inverted from any cause the walls of the respective receptacles will become. parallel and the contents thereof will be caused to com mingle to form a gas, as above explained.

It will thus be obvious that I have pro vided a cheap, durable, and eflicient automatic fire-extinguisher which will readily perform .the functions for which it is intended, and while have specifically described the best-known manner of accomplishing the desired result I would have it understood that I reserve the right to make such changes and alterations as would properly come within the scope of the appended claims without departing from spirit thereof.

I claim 1. A fire-extinguisher consisting of a pivoted receptacle, an inner receptacle located within the first-named receptacle and adapted to contain a liquid to be discharged into the first-named receptacle when inverted,

. and a cap provided with perforations located in the mouth of the inner receptacle.

2. A fire-extinguisher consisting of a piv located between the mouth of the inner receptacle and the outlet of the first-named reccptacle.

3. A fire-extinguisher consisting of a pivoted receptacle having an outlet, an inner receptacle located within the first-named receptacle and adapted to contain. a liquid to be discharged into the first-named receptacle when inverted, a cap provided with perforations located in the mouth of the inner receptacle, and a perforated disk located between the mouth of the inner receptacle and the outletof the first-named receptacle.

4. A fire-extinguisher consisting of a pivoted receptacle, an inner receptacle located within the first-named receptacle and adapted to contain a liquid to be mingled with the contents of the first-named receptacle when inverted, said inner receptacle being pivotally mounted in the first-n amed receptacle in such a manner that it always in a vertical position irrespective of the angle of m clination or the hanging position of the firstnamed receptacle.

In testimony whereof I afiix my signature in presence of two witnesses.
