Specification of Letters Patent.

Patented Sept. 24, 1912.

Application filed November 29, 1911. Serial No. 663,340.

ingto 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.

My invention relates to new and useful improvements in sprinkling devices and more particularly to adevice ofthe class described, adapted to' be used in extinguishing fires. r The object of my invention is to provide a device which maybe positioned in the upper part of a rooxn'a'ndwhich is normally out of operation and which will be auto? matically opened in case of fire.

A further object of my invention is .to so constructthe nozzle that the fluid directed therethrough will be given a rotary movement, causing the same to spread.

Other objects and advantages will be hereinafter set forth in the specification and pointed out'in the claim.

In the accompanying drawings I have shown the preferred form which my invention may. take.

In said drawings, F igurel 1s a longitu dinal sectional view through the noazle. Fig. 2 is a horizontal sectional view therethrough, as seen on line 22 ,Fig. 1, and, Fig; 3 is a vertical sectional view therethrough as seen on 1ine33, Fig. 1.

Referring to the drawin 's in which similar reference numerals designate corresponding parts throughout the several views, 4 is a casing, which is-separated into an upper and lower compartmentby means of a partition 5. The upper portion of the casing is substantially cylindrical and is directed rearwardly and externally screw threaded, as shown at (1, so that a suitable supply pipe for water or other fluid may be connected thereto.

The lower compartment is substantially semispherical, as shown in Fig. 2, said semispherical portion being directed downwardly and provided at its center with an outlet opening 7, through which the fire extinguishing fluid is adapted to be directed. The partition 5 is provided at diametrically the openings 8 to assist in giving the extinmoveinent in the opposite points with openings 8 therein, said openings being inclined in opposite directio'ns so that the fluid passing there through into the lower compartment will be given a rotary movement-therein, as will be clearly apparent to those skilled in-the art to which this invention appertains. The walls of the upper compartment are also inclined, as shown at 9 and 10, over guishing fluid a rotary lower compartment.

In order that the outlet opening 7 me be normally closed, I provide a valve 11, which is adapted to be normally held in said open ing. The valve 11 is preferably provided with an annular flange 12 adapted to engage the outer surface of the-casing, a suitable washer 13 being interposed between said flange and said casing so as to prevent leakage. The casing is provided with diametrically 'opposed downwardly. directed. stems 1 1 and 15, the lower end of the'stem 15 being preferably screw threaded. A bar 16 having a bifurcated end, is pivoted to the stem 14, as shown at 17 the opposite end of saidbar being provided with an aperture 18 therein adapted to receive the threaded end of the stem 15. The bar 16 is also provided at its center with an interiorly screw threaded aperture 19, adapted toreceive a bolt 20 .therethrough; The inner end of the bolt 20 may be enlarged, as shown at'21, and is adapted to be turned against uhe outer end of the valve 11. A nut 22, forl ed of easily fusiblemetal, is turned upon the outer end'of the screw threaded stem 15, so as. to hold.the bar 16 in position as shown in Fig. 3. The bolt 20 is .then turned so as to tightly seat the valve 11 in the opening in the casing. A spring 23 has one end-,seated in a recess 24; formed in the casing, its other end bearing against the bar 16 and tends to move the bar away from the stem 15.

' In operation the nozzle is positioned in a room near the ceiling thereof and is connected to a supply pipe for water or other desired fire extinguishing fluid. Should a fire occur in the room. the heat thereof will quickly melt the fusible nut 22 and. the spring 23 will move the bar so that the bolt 20 will be moved out of the path of the valve 11. The pressure of the water or other fire extinguishing fluid will iuuncdi ately unseat the valve, and owing to the fact charge that the water will be given a rotary movement in the lowerportion' of the casing, the same will be sprayed "and directed into all arts of the room, so that the fire will be uickly extinguished.

I/VhileI have shown and described my invention as being disposed so that the disor outlet epening is downwardly directed. I desire it to be understood that I may direct the same upwardly or in any other direction, so that upon the'occurrence' of a fire in a predetermined location, the fire extinguishing fluid will be mostadvantageously directed upon the flames.

From the foregoing description it will be seen that I have provided a tire extinguishing device, which is normally inoperative and which will quickly be brought into operation on the occurrence of a fire. It will also be seen that owing to the constructionof my device, the fireextinguishing fluid will be directed over a large surface.

IVhile I have shown the preferred forn which my invention may take, I'desire it to 'be understood that certain modifications Copies? 01 this patent may be obtained for .I may be madefive cents each, by addressing the Washington, D. 0.

therein without departing from the spirit and scope of my invention. What I claim as new is: The combination with a rotary sprinkler having inlet and outlet openings therein; of a pair of integral stems depending from said casing, the lower end of one of sai stems being reduced and threaded, a bar.

pivoted to the other stem, means carrid thereby for closing said outlet opening, a

the reduced end of fusible nut threaded on the free end of said said stem and engaging bar, and and engaged against the upper face of said bar whereby when the free end of the latter is released it will be thrown into a vertical position and out. of the path of the fluid issuing from the outlet opening.

In testimony whereof I have signed my name to this specification in the presence of two subscribing witnesses.
