Description

Filed Oct. 11, 192a G SCHWORETZKY HIGH PRESSURE GAS DEVELOPING CARTRIDGE April 8, 1930.
Patented Apr. 8, 1930 I UNITED STATES PATENT; OFFICE eusrnv SCHWORETZKY, or Essrmem: A. 1a., GERMANY, ASSIGNOR, BY mnsnn .AS-
SIGNMENTS, TO THE FIRM G;ES. M. 3. BL, OF BERLIN, GERMANY HIGH-PRESSURE GAS-DEVELOPING CARTRIDGE Application filed. October 11, 1926, Serial No. 140,967, and in Germany October 21, 1925.
able fire extinguishers as well as for the preparation of sparkling beverages in bottles in which the perfectly tight closure is eifected,
merely by forcing a tapering part into a preferably tapering bore in or over the tapering end of another part consisting of the same material. The seal thus produced which is able to withstand hundreds of atmospheres of pressure without becoming untight is not produced by grinding one part accurately into or over the other in the manner of airtight glass sto pers or caps, but by the molecular eating 0? one part into the other, the parts consisting preferably of soft iron.
lhe simplest seal according to my invention is produced by forcing a plug or truncated cone into the correspondingly shaped bore in the neck of the cartridge. In gas cartridges in which the closing as well as the opening should take place at the charging place the part forced into the bore of the neck of the cartridge is a bushing in the form of a receptacle the bottom. of which is so thin that it may be destroyed by driving in a striking pm; Some embodiments of my invention are illustratedin the drawing afiixed hereto.
In the drawing shows:
Fig. 1, a sectional elevation of a cartridge in which a tubular bushing is employed as closing part,
Fig. 2, a longitudinal section through the lower portion. of a cartridge for a fire extinguisher in which a solid plug is employed for closing the cartridge,
Fig. 3, the closed chargingopening according to Fig. 1 on a larger scale, I
Fig. 4, a longitudinal-section throu h the bushing employed in Figs. 1' and 3, an
Fig. 5, a small cartridge for the manufacture of a sparkling beverage in a siphon in sectional elevation.
Like parts are indicated by like letters ofreference in all the figures of the drawing. Referring to the drawing 6 is a sealing member forced into or over the opening of the cartridge. In the fire extin uisher car-.
tridge according to Figs.1 2 an 3 this closing member is secured in the working position by a screw 8. As shown in Figs. 1, 3 and 4 the enlarged inner end of the closing member I) is fitted into a recess in the screw 8. The bottom 03 of the closing member b is so thin that'it forms a mere membrane and may be perforated or destroyed by the,- striking pin '5. This pin '5 is guided at one end by the locking screw 8 and at the other end it is riveted into the diaphragm m solderedon and protecting the opening mechanism of the bottle. When the cartridge is rendered operadiaphragm is also driven inwards.-
- In the small siphon cartrid e illustrated in Fig. 5 the member 6 is em oyed in such a manner that it is not-force into the cartridge neckbut over it.
Various changes may be made in'my improved cartridge'within the" ambit of my claims without departing 'fromthespirit of my invention or sacrificing any of its advantages.
I claim as my invention 1. In a high-pressure gas developing cartridge for a portable fire extinguisher a sealing device for the charge opening, .comprlsing in combination, a tapering bushing with thin bottom, fitting into the tapering bore of the charge opening, a screw for locking said bushing in place, a diaphragm soldered to the mouth of said charge opening, and a striking pin riveted at one end into said diaphragm and guided at the other end in said locking screw.
2. A closure for metal containers comprising plug and socket members having com-.
plementary wedging sealing faces, said mem together, and means for forcing the members into sealing relation.
4. A closure for metal containers as defined in claim 3, the plug member consisting of a tapered bushing and the socket member consisting of a tapered charge opening on the container.
In testimony whereof I aflix my signature.
GUSTAV SCHWORETZKY.
