FIRE EXTINGUISHER DEVICE Filed July 22. 1933 HNVENTOR A.Mielzrzer ATTORNEY Patented Mar. 13, 1934 UNETE STTES PATENT OFFICE FIRE EXTINGUISHER DEVICE Anton Mietzner, New York, N. Y.
Application July 22, 1933, Serial No. 681,675
2 Claims.
The main object of this invention is to provide a cartridge filled with fire extinguishing crystals which is emptied by a thrust of the arm over a burning area, the chemical reaction of the crystals and fire forming an enveloping cushion free from oxygen to smother the fire.
Another object of this invention is to provide a crystal filled cartridge which has spreader fingers over its open end in order to evenly spread the crystals as an enveloping sheet over the fire.
The above and other objects will become apparent in the description below, in which characters of reference refer to like-named parts in the drawing.
Referring briefly to the drawing, Figure 1 is a perspective view of the cartridge showing the spreader fingers in place thereon.
Figure 2 is a fragmentary sectional elevational view showing the means for locking the spreader fingers on the cartridge.
Figure 3 is a perspective view of the top spreader finger.
to be the most desirable and useful.
Near the open marginal edge 12 of the cartridge at spaced apart positions around the periphery thereof triangular depressions or pockets, 13, are formed. These pockets are provided with shoulders, 14, the purpose for which will be more fully hereinafter described.
These pockets may be provided at selected positions to permit adjustment of the spreader fingers.
The spreader fingers are preferably two in number, an upper and lower and are constructed as follows: A triangular trough, 15, is formed by flaring a pair of converging walls, 16 and 17,
angularly.
The reverse surface, 18, of these walls serve as the spreader faces.
At the extremities of these walls ears, 19, rise abruptly and at a slight angle. These ears, 19, are joined by longer tongues, 20, which have teeth, 21, formed thereon. The latter are adapted to register in the previously described pockets, 13, in such manner so that they rest shoulder to shoulder.
The cartridge is adapted to contain a crystalline mass consisting of proportionate parts of the following:
infusorial earth, or infusorial silva, or fossil dust, of which 10 per cent by weight is used, 50 per cent natrium bicarbonate,
15 per cent chlorammonium, and 25 per cent alum. These ingredients are evenly mixed and distributed in the mass, and the latter is then filled into the cartridges which are adapted to be mounted in all prominent positions such as household or business establishments by a hook which may be provided. The device may also have the conventional type of cover applied theretc so as to prevent the contents of the cartridge from becoming stale.
In use, the cartridge is grasped in the semiclenched hand, the cover is removed and the open end of the cartridge is thrust toward a fire and the crystals are evenly distributed in sheets of powder by the converging walls, 16 and 17, of the spreader fingers which intersect each other on the open end of the cartridge. These fingers may be selectively removed or replaced by disengaging the teeth 21 on the resilient tongues 20 from the recesses or pockets, 13, formed in the wall of the cartridge.
It is to be noted that certain changes in form and construction may be made without departing from the spirit and scope of the invention. The bottom finger, 22, illustrated in Figure 4, is of similar construction to the other finger, but is provided with a saddle, 23, in which the center of the first named finger is adapted to rest.
I claim:
1. A cartridge containing a filling of infusorial earth, said cartridge being open at one end crossed fingers on said cartridge, converging walls on said fingers adapted to spread the contents into divergent sheets, tongues on said fingers, teeth on said tongues, and means on said cartridge receiving said teeth for releasably securing said fingers in place.
2. A cartridge containing a filling of infusorial earth, said cartridge being open at one end crossed fingers on said cartridge, converging walls on said fingers adapted to spread the contents into divergent sheets, tongues on said fingers, teeth on said tongues, said cartridge having pockets therein adapted to receive said teeth to releasably secure said fingers on said cartridge.
ANTON MIETZNER.
