UNITED "STATES SAMUEL S. SCHWAB, F TOLEDO, OHIO.

FIRE EXTINGUISHER.

Application filed November 14, 1923. Serial No. 674,613.

To all whom it may concern.

Be .it known that I, SAMUEL S. SCHWAB, a citizen of the United States, and a resident of Toledo, in the county of Lucas and State of Ohio, have invented a new and useful Fire Extinguisher, which invention 1s fully set forth in the following specification.

My invention has for its object to provide a combined steam and fire-extinguishing liquid distributor whereby the combined fire-extinguishing effects of the steam and liquid may be produced in a room, the steam.

operating to heat and spray thefire-extinguishing liquid into all parts of the room.

My invention has for its object other foatures and advantages which will appear from the following description and upon examination of the drawings.

The invention may be contained in structures, having details that vary. To illustrate a practical application of the invention, I have selected oneof such structures and shall describe it hereinafter. The structure selected is shown in the accompanying drawings.

Figure 1 of the drawings illustrates a top view of the apparatus. Fig. 2- illustrates a sectional view taken on the line 2-2 indicated in Fig. 1. I

A source of steam supply is connected to the apparatus by pipe 1, in which is located an opening valve 2 for permitting steam to enter the apparatus. The valve 2 controls the supply of steam to the pipe 3 which extends through a container 4. The container 4: is supported by means of suitable brackets 5 that may be located on a wall or other supporting structure.

The container 4 is filled with a fire-extinguishing solution, or liquid, such as carbon tetra chloride. To fill the container 4 the threaded plug 6 may be removed from a suitable opening and the liquid inserted in the container. A siphon 7 is located in container 4: and is formed of a pair of pipes 8 and 9. They are connected together by a U 10. The pipe 8 extends to near the bottom of the container, while pipe 9 extends through the bottom to the sprayer 11, lhe

bend in the U being located slightly above the level of the liquid in the container 4 to prevent the flow of the liquid from the container through the siphon 7.

The sprayer 11 is formed of a coneshaped nozzle 12 that is located in front of elbow 13 which is secured to the lower end of the pipe 3 at a point below the bottom of the container 4. The nozzle 12 is secured in position by means of the threaded shell 14; of the sprayer 11. This forms a chamber 15 between the nozzle 12 and the wall of the shell 14 to which the siphon 7 is connected, the lower end of the pipe 9 being provided with an elbow that is threaded into the shell 14. A suitable annular plug 16 is threaded into the shell 14 to form an outlet for the mixed vapor and steam.

When the valve 2 is opened, the steam will pass down through the pipe 3 and draw the liquid from the container through the siphon 7 and distribute the mixture of the steam and liquid vapor throughout the room in which the apparatus is located. In order to secure an immediate action of the apparatus, the top of the container is connec-ted to the pipe 3 by means of the pipe 17. This will transmit the pressure within the pipe 3 to the surface of the liquid contained within the container 4 and cause a rapid movement of the liquid to the'sprayer 11. The liquid, moreover, is heated by the steam that it comes in contact with, and also by the heat transmitted through the pipe 3 to the liquid in the container which increases the fire-extinguishing efficiency of theliquid. The steam in itself is a fireextinguishing element, and, moreover, it cooperates to increase the efiiciency of the fireextinguishing liquid as well as cause its dis tribution.

I claim In a fire extinguishing apparatus, a container, a steam pipe connected with a source of supply of steam and extending through the container, a siphon located in the container extending through the bottom of the container, one end of the siphon terminating near the bottom of the container and within the container, and the other end terminating near the bottom of the container and tance beyond the said nozzle and forming on the outside of the container, a nozzle a spraying and suction means for drawing 10 connected to said steam pipe, a shell surthe material from the container, means for rounding the said nozzle, the siphon conconnecting the steam pipe With the top of nected to the said shell, the said shell havthe container.

ing a ring forming an annular opening In testimony whereof I have hereunto about the end of the nozzle for the said signed my name to this specification.
