J. E. HEISENFELDT PIRE EXTINGUISHER Filed spt. 30 1942 INVENTOR JOHN E..HE|SENFELDT ATToRNEYs Patented Oct. 3, 1944 UNITED STATES PATENT OFFICEv FIRE EXTINGUISHER John E. Heisenfelt, Wauwatosa, Wis. b Application September 30, 1942, Serial No. 460,186 2 claims. (emaa- 88) This invention has for its object to provide a fluid distributor, for powder, flux or any fire extinguishing chemical. 'I'he invention is particularly adapted for use as a portable emergency fire extinguisher, the same being hand manipulated, it being understood that the device is particularly adaptedfor use in connection with small fires occurring in shops, public buildings, private houses, all kinds of Vehicles and also incendiary fires occurring through explosive bombs.
The specific object of my invention is to provide a container for fluid or powders having aA valve controlled discharge tube extending therethrough in communication With a hand manipulated air pump whereby the contents of said container is discharged in a jet or spray in a selected predetermined volume.
Another specific .object of my invention is to provide the distributor tube with a series of valve controlled ports throughout its length wherein the volume of fluid discharged may be progressively regulated by selected adjustment of the valve arrangement.
Another object of my invention is to provide a bellows attached to the container' and a tube in communication with the bellows, the same extending through the container having a plurality of ports under the valve control, whereby the contents of said container may be discharged under forced draft in predetermined quantities.
With the above and other minor objects in view, my invention consists in certain peculiarities of construction and combination of parts as will be hereinafter set forth with reference to the accompanying drawing and subsequently claimed.
In the drawing:
Figure 1 represents a plan view of a fluid container embodying the features of my invention.
Figure 2 is an enlarged section side elevational view of the same, the section being indicated by line 2-2 of Figure 4.
Figure 3 is a cross section of the container, the section being indicated by line 3-3 of Figure 2.
Figure 4 is a longitudinal sectional plan view of said container, the section being indicated by line 4-4 of Figure 2.
Referring by characters to the drawingl indicates the fixed plate of a bellows and 2 the reciprocative plate of the same, having an air intake valve control port 3 formed in the central portion of said plate. v
The plates are connected by the usual flexible bellows wall 4 and each plate has extending from its Irear portion handles 5, 5'. The fixed plate l inv this exemplification of my invention has secured thereto a rectangular'container 6 provided With a cap controlled'filling opening' 1.
The fixed plate I of the bellows has secured therein the mouth 8 of a discharge tube 9, which tube is elbowed from its mouth and extends longitudinally through the container adjacent to the bottom wall of the same. The discharge end of the tube projects beyond the container and said tube within the latter is formed with an upwardly positioned series of ports ID, 10', IU. These ports are preferably formed with flaring hopper mouths as shown, adapted to conveniently trap the contents of the container, which contents may be of a powder or fluid form.
It Will be noted in this exemplification of my invention that port |0 is of maximum area and the remaining ports are progressively reduced in size.
Reciprocatively mounted in the tube is a sleeve Il, Which sleeve in its inoperative position is extended downwardly into the tube, whereby all of the ports are closed. When in the position shown in Figure 2 of the drawing the valve sleeve is pulled outwardly so as to expose the port I 0.
While Ir have shown a plurality of ports progressively decreasing in size from the first port, it is understood that the number of ports may be reduced or increased indefinitely as the conditions warrant and in some instances a single port only may be used.
It will be noted that when the device is in operation, the bellows must be held vertically for proper functioning. The container, carrying a chemical fire extinguishing powder, is also vertically disposed, with a ported bottom discharge tube. The powder will thus feed downwardly, by gravity incidental to the gyrations of the bellows plate I in conjunction with its associated plate 2 and will positively loosen and shake the powder down and thereby feed the same by gravity through the valve opening.
Furthermore, it should be understood that while I have shown a reciprocative valve sleeve H, for controlling the ports, obviously I may in some instances employ a rotary sleeve for accomplishing the same results, it being understood that under such conditions the sleeve would have openings therein to register with the ports.
From the foregoing description it Will be readily understood that in the operation of the container under fire emergency conditions, as best shown in Figure 4, the sleeve would be pulled out to a selected position With reference to the end of the tube and said position would be gaged by the indices I, 2, and 3. When as the index 3 is exposed at the end of said tube, the full capacity of the group of ports would be brought into play. The operator would then manipulate the bellows handle 5 back and forth, whereby a volume of air would be discharged through the tube, With each impulse of the bellows and the fire extinguishing powder, passing through the ports, Would co-mingle With the aii` and would be discharged in a j'et or spray upon the blaze to be extinguished. In this connection, it Will be noted that due to the reciprocative impulse imparted to the bellows the contents of thecontainer would be agitated, facilitating the discharge of said powder contents into the tube.
It will be noted that I have shown the tube opening in hopper shape. found that a rectangular cut-out opening extending approximately 2/3 of the diameter of the pipe leaving sharp corners, will cause the powder to flow more freely While the pressure of air is passing through the tube.
In practicel the bellows plates are connected at the real' With a cross str'ap in order to take the I strain from the flexible bellows material When the said bellows is fully distended.
From the foregoing description it will be noted that a simple and iriexpensive appar'atus for the purposes described is produced and it should also be noted that the various parts of said apparatus may be made from any plastic material or from some fibrous material, similar to cardboard or the like, it being unersto'od that provision for manufacturing, with these various materials Visv particularly desirable under present restrictions as to metal.
I While I have shown and described one exem- In practice' I have plification of my invention minutely as to detal, it is understood that I may vary the structural features of the same within the scope of the claims.
I claim:
1. A fire extinguisher for powder comprising a vertically positioned powder container having an upper filling opening, a bellows plate secured to one of the vertical walls of the container and extending beyond the end of said wall, a handle secured to the bellows plate extension for gyrating the powder container incidental to actuating the bellows, a tube extending through the bottom portion of the container having a plurality of upwardly fiared mouth ports communicating with saidcontainer, the inner end of the tube terminating in an elbow extending through the bellows plate extension, an open ended sleeve telescopically mounted in the tube for controlling the ports, a handle carried reciprocative bellows plate having a valve therein and a flexible bellows wall connecting the said plates.
2. In a distributer for chemically treated powder, vertically disposed bellows plates hingedly connected by a flexible wall, each plate being provided with a horizontally actuated handle, an air intake valve in one plate, a vertically disposed powder container secured to the other plate, whereby said container is gyrated incidental to a bellows movement, the said container having an upper filling opening andv a discharge tube extending from the container bellows plate and through the bottom portion of said container having vertically disposed feed ports therein and communicating With said container, and means for controlling the feed ports.
