Abstract: 25,971. Lemoine, L. Nov. 27. AÙrating liquids; siphon vessels.-Siphon bottles, previously filled with liquid, are charged with gas from a cartridge or receptacle of compressed or liquefied carbonic-acid gas by means of the apparatus shown in Fig. 1. The head of the siphon bottle is made capable of being unscrewed, to permit the bottle to be filled with the liquid directly through the neck, after which the head is screwed on, and the bottle charged with gas through the delivery nozzle d. The lever 11 of the bottle is also modified for engagement with the cam lever e of the charging-apparatus. The apparatus is mounted on the elongated frame 1, which carries the cam lever e, the block 6 for engaging the head of the siphon bottle, and the junction piece 2 for engaging the nozzle d of the bottle. The gas cartridge or receptacle 14 is adapted to be connected to the lower end of the junction piece 2, which is provided with suitable means for opening the valve 13 of, or puncturing, the cartridge, to effect the delivery of the gas. The cartridge 14 screws into the socket 15, 16, which is secured on the extension a of the junction piece 2 by the nut 17, the valve 13 being opened by the tubular prolongation h of the extension a, when the socket 15, 16 is pressed upwards against the action of the spring 18. The cam 5 on the lever e acts through the spring-controlled plunger 7 on the block 6, which is held up to the cam by springs 10, Fig. 3. On depressing the cam lever e, the nozzle d is pressed against the washer c on the junction piece 2, by the cam 5 acting through the block 6 on the head of the siphon. On the further depression of the lever eÀto the position e<1>, this lever moves the siphon lever 11 into the position 11<1>, to open the siphon valve f, and locks the lever 11 in that position. The cartridge 14 is then raised, by means of two lugs on the socket 16 projecting through the frame 1, to deliver the gas. The lugs on the socket 16 are engaged by two draw-bars, mounted on the frame 1 and connected by a cross-bar 26, these bars having finger-holds adapted to be engaged by the fingers of the hand which operates the lever e. The junction piece 2 is provided with a safety-valve 27, and with suitable packing-washers 19, 20, &c. The chamber 28 in the junction piece is adapted to receive a filtering-material, such as metal shavings, pumicestone, spongy platinum, &c., to free the gas from impurities. A pressure-reducer may be placed in the channel 3. In a modification, the cartridge is inserted in a recess in the lower end of the frame 1, and is raised, with the frame, by the action of the cam 5. This cam acts on the block 6 through a screw, which can be adjusted for wear &c. The junction piece, which is capable of sliding on the frame 1, is normally pressed downwards by springs similar to those shown in Fig. 3, and is fitted with a reducing-valve and a safety-valve. The reducing-valve is carried by a diaphragm and controlled by an adjustable spring, to regulate the pressure of the gas delivered. Any other suitable pressure reducer may be employed. As shown in Fig. 1, the frame 1 is loosely pivoted to a protector adapted to surround the bottle. The protector consists of a cylindrical guard m, and two shoulder and neck segments n, o pivoted to the part m, the frame 1 being pivoted to the part o, or connected to it by springs &c. When the parts n, o are closed round the bottle, they are secured automatically by catches.
