Abstract

15,652. Durafort, V. E. J. July 16. Stoppers.-Relates to means for charging liquids with gases, and especially applicable to the charging of water in bottles, gasogenes, or siphons with carbonic acid. The apparatus consists of a reservoir 1 of steel or the like, having screwed on its upper end a removable cap 2 for allowing the introduction of a steel capsule 3 provided with a valve 4 and containing the compressed or liquefied gas. This capsule is placed in a carrier 5, and the valve 4 is opened by screwing down a rod 6 so that the gas passes through the perforations 5* into the container 1, whence it passes through a pressure-regulating valve to the bottle &c. In the valve shown in Fig. 1, the gas passes by passages 9 and 10 to an inner chamber 11, where it exerts pressure on a diaphragm 12, whereby, through a piston 13, pressure is exerted on a diaphragm 14, and, when this pressure is sufficiently great to counteract the strength of the spring 15, it causes the valve 16 to close the passage 9. The gas passes away from the chamber 11 through passages which can be blocked by a screw plug 18 and are provided with a safety-valve 19, and then passes through a strong tube 20 to a cap 28 fitted on to a special stopper 21, which may be provided with the usual siphon attachments. The gas flows into the bottle by forcing back the valve 22 against the action of the spring 23, until the increased pressure in the bottle closes the valve 22. The bottle, if not a siphon, is held upside down while its contents are being aerated.
