Description
Jan. 27, 1931'. L. J. DUGAS FIRE EXTINGUISHER CONTAINER Filed Sept. 20, 1928 vlnlllllldrlllllll 1 FIIIIIZIlI/IIIIII I Patented Jan. 27, 1931 UNITED STATES PATENT OFFICE LODIAS J". DUGAS, OF CHICAGO, ILLINOIS, ASSIGNOR TO DU-GAS CORPORATION, OF
' NEW YORK, N. Y, A CORPORATION OF DELAWARE FIRE-EXTINGUISHER- CONTAINER Application filed September.20, 1928. Serial No. 807,131.
This invention relates to a fire extinguisher container and more particularly to a container for dry extinguishing powders.
It is therefore an object of this invention to provide a tank or container for dry powdered chemicals having fire extinguishing properties and further to provide means for introducing a gas under pressure into the container to discharge the chemical in a high pressure stream of the gas.
It is a further object of this invention to provide means for distributing the gas introduced into the fire extinguisher container so as to prevent the extinguishing powder from caking and hanging upin the container. Other and further objects of this invention will become apparent from the disclosures in the specification and accompanying drawings. I
The invention (in a preferred form) is illustrated on the drawings and hereinafter more fully described.
On the drawings:
Figure 1 is a sectional view of a container embodying the principles of my invention, with parts broken away and in section.
Figure 2 is a detail sectional View of a modified form.
The reference numeral 1 indicates a tanl or container of the desired capacity and preferably formed of semiannealed seamless copper, brass protector bands 2 being arranged therearound and welded thereto to reinforce said tank. The top of the tank 1 is provided with an upstanding and outwardly turned flange 3 internally threaded to receive a removable top or cap member 4. Gaskets 5 are provided for forming a tight joint between said cap 4 and an inner shoulder 6 formed around the opening of said tank 1. Said cap 4 is provided with a handle I 7 to facilitate manual operation of the same and furthermore to provide means for carrying the tank 1.
The'lower end of said tank 1 is open aslat 8. A funnel-shaped bottom 9, however, is disposed a suitable distance above said open lower end 8 and secured to the walls of said tank 1 by-any suitable means, as by forming a. head 10 to receive the upper edge of said bottom 9. Said funnel-shaped bottom 9 merges into a curved spout 11, which passes through the tank wall adjacent to said lower end 8 and is welded or otherwise secured thereto. Said spout 11 extends beyond the wall of said tank 1 in an upwardly and outwardly projecting end portion 12, to which is adapted to be attached a flexible hose 13 provided with adischarge nozzle 14. The nozzle 14 is controlled by means of a valve or pet cock 15 positioned near the end thereof.
A tube 16 enters the top of said tank 1 and extends downwardly to a point adjacent the constriction of said funnel shaped bot-tom 9. Said tube 16 is curved for a part of its length but its lower end is straight and positioned centrally of the tank 1 so that a gas, such as nitrogen or air passing through said tube 16 will be directed into the curved spout 11. The lower end of said tube 16 is tapered as at 17 to effect a high Velocity of gas. Perforations 18 are provided at different points along the length of the tube 16 in order that the gas may be directed against the Walls of the container or tank 1. The upper end of said tube 16 is threaded as at 19 for connection to a hose 20 leading from a high-pressure gas cylinder (not shown).
The tank '1 is adapted to befilled with a fire extinguishing powder and the gas under pressure directed through the tube 16 to forcethe powder out through the spout 11, the hose 13 and nozzle 14. Due to the high pressure of the gas employed, the stream of gas discharging from the tube nozzle 17 will act-as an injector to draw the powder along with it as it passes out through the spout 11. a
The gas issuing from the perforations 18 serves .to stir up the powder in the container and prevent it from caking and hanging up. Consequently a high pressure stream of gas carrying the fire extinguishing powder is a reduced end 24. Perforations 23 are formed in the nozzle 22 to permit gas to be discharged to the sides as well as out of the reduced end 24. The distribution of the gas in this manner prevents the powder from lumping up in the funnel-shaped bottom 9 and blocking the tube 11.
I am aware that numerous details of the process may be varied through a wide range without departing from the principles of this invention, and 1 therefore do not purpose limiting the patent granted hereon, otherwise than necessitated by the prior art.
I claim as my invention:
1. A fire extinguisher, comprising a container adapted to be filled with a dry extinguishing powder, having a funnel sha ed bottom, the side wall of said container being extended downwardly to form a supporting base, a tube leading from the constricted portion of said bottom outwardly through said continued wall and a second tube extending into said container and terminating adjacent the constricted portion of said funnel shaped bottom for directing a gas under pressure into said first tube.
2. A fire extinguisher, comprising a container adapted to be filled with a dry extinguishing powder, having a funnel shaped bottom, the side wall of said container being extended downwardly to form a supporting base, a tube leading from the constricted portion of said bottom outwardly through said continued wall and a second tube extending into said container and terminating adjacent the constricted portion of said funnel shaped bottom for directing a gas under pressure into said first tube, said second tube being provided with spaced perforations along its length within said container.
3. A fire extinguisher, comprising a container adapted to be filled with a dry extinguishing powder, having a funnel shaped bottom, the side wall of said container being extended downwardly to form a supporting base, a tube leading from the constricted portion ofv said bottom outwardly through said continued wall and a second tube extending into said container and terminating in a straight reduced nozzle adjacent the constricted portion of said funnel shaped bottom for directing a gas under pressure into said first tube.
4. A fire extinguisher, comprising a container adapted to be filled with a dry extinguishing powder, having a funnel shaped bottom, the side wall of said container being extended downwardly to form a supporting base, a tube leading from the constricted portion of said botton outwardly through said continued wall and a second tube extending into saidcontainer and terminating adjacent the constricted portion of said funnel shaped bottom for directing a gas under pressure into said first tube, said second tube In testimony whereof I have hereunto subscribed my name.
