The object of this improved apparatus is to generate carbonic acid gas and charge liquids with the same in such a way that no gas can escape during the process, a difficulty that has hitherto attended apparatus intended for this purpose. The invention consists in attaching a bottle to a chamber, in the lower part of which a throttle valve is placed. The bottle contains the super-carbonate of soda and tartaric acid, from which carbonic acid is generally made by the addition of water; water is placed in the chamber which contains'"the valve. The whole is so arranged that the valve may be opened by the tilting of the water or acid chamber and the gas generated, and the liquid in the receiver charged without the least chance of gas escaping. It is the invention of Thomas Warker, of New York City, and it is patented this week.
It’s Time to Stand Up for Science
