Specification of Letters Patent.

Patented ov. 6, 1906..

Application filed November 20, 1905. Serial No. 288,283.

` To all whom it may concern:

Be it known that I, FERNANDO YosT, a citizen of the United States, residing at Weehawken Heights, in the county of Hudson and State of New Jersey, have invented certain new and useful Improvements in Fire- Extinguishers and I do declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

This invention relates to improvements in carbonio fire-extinguishers,

The object of the invention 1s to provide a {ire-extinguisher of this character the inverting of which causes. the chemicals contained therein to mix, thus generating an acid gas which when discharged into a fire by suitable ap aratus connected with the device the lire Wi l be extinguished.

Another object of the invention is to provide a device of this character having operating discharge mechanism, which is operated by the overpressure of gas within the cylinder to automatically release said gas, thereby preventing an explosion'andbursting of the device.

A further object is to provide an improved means for holding the acid-container in suitable osition within the cylinder, whereby said iiolding device and the acid-container may be readily removed from the cylinder.

With the above and other objects in view the invention consists lof certain novel fea- 'f tures of construction, omnbinatlon, and arrangement of parts, as'will be hereinafter den scribed and claimed.;

' In the accompanying drawings, Figure l. 1s

a vertical sectional 'view of the device, showing the parts in the position they assume when the deyice is not in use and in an upright position and showing in dotted lines the position of and the manner 1n which the safety closing disk or plate is ruptured to prevent the exploding of the extinguisher by A ovcrpressure of the gas within the cylinder. Fig. 2 is a similar View showing extinguisher inverted and the parts therein in position for use, and Fig. 3 is a top plan View of the cage for holding the acid-container -rernovedfrom the cylinder.

Referring more particularly to the drawings, 1 denotes the cylinderjwhich may be of any suitable form and construction. In one end of thecylinder is secured an exteriorlythreadedcollar 2, on the inner side of which 3. On the lugs 3 is supported an apertured plate or disk 4, forming part of an acid-container cage 5, the sides of which are constructed of suitably-bent wire rods 6, secured at their lower ends to a plate 7. One of the `rods 6 is pivotally connected at its lower end to the plate 7, as shown at 8, and is bent downwardly at its opposite end to form a' 'loop 9, which is adapted to be sprung into engagemeiit-with a vrecesslO, formed in the plate or disk 4, and into engagement with a is formed a series of inwardly-projecting lugs notch 12, formed yin one side of said recess 10, Y

formed an enlarged head 16, which when the.

bottle is in an upright position is seated upon the top of the same, as shown in Fig.`1, and which when the device is inverted will cause the stop er to drop out of engagement with the bott e and to rest upon the plate or disk 4, thus ,permitting the discharge of the acid from the bottle.

On the threaded upper end of the-collar 2 is adapted to be screwed an apertured cap 17, on the inner side of which is formed an Iannular seat 18, in which is ada tedtobe placed a flexible closing late or disk 19, which is preferably formedp of thin metal. On the disk 19 between the same and the. end ofthe collar 2 is -arranged an elastic gasket 20, by

means of which the upper open end of the cylinder is hermetically sealed when theap 17 is screwed down in place. On the outer side of the cap 17 is formed an outwardly-- curved protecting frame or spider 21, in the center of which is formed a screw-threaded aperture 22, through which is adapted to be screwed a threaded piercing-point 23, the inner end' of which is adapted to'be engaged by the flexible disk 19 when the latter is distended by the pressure of gas within the cylinder, thus piercing or rupturing said disk and forming a discharge-outlet through no which the liquid may pass, thus relieving the IOO pressure of the same withinthe cylinder and aai-m50 preventing the explosion 01 bursting of the i scribed, the combination v si latte?.
