To all whom t may concern.- l

Be it known that I, VICTOR DURAFORT, a citizen of France, residing at Paris, France, have invented certain new `and useful Improvements in Apparatus for Containing Compressed Carbonic Acid and Charging Water or other Liquids Therewith, of which the following is a speciiication. My invention has for its object to provide siphons and cartridges containing compressed carbonic acid wherebyaerated water or other liquid may be produced charged with any desired proportion of gas, the arrangement being such that any proportion of the carbonic acid or the whole of it can be admitted to the water or other liquid to be impregnated therewith.

I will describe my invention with reference to the accompanying drawings.

Figure 1 represents in section an apparatus according to my invention. Fig. 2 is a section of the upper part of the head at right angles to Fig. 1. Fig. 3 is a transverse secg tion taken along the line 1 1 of Fig. 2. Fig. 4 is an enlarged section of the upper part of the carbonic-acid cartridge or container.

2 represents the said cartridge or container, which is inclosed in a chamber 5 at the top of the Siphon-head. The part 4. of this chamber may be of cast-iron or other suitable material, with the usual or any suitable cocks and valves for drawing o the aerated liquid, and when the cartridge is in place thetop part 3 is screwed onto the lower part 4 by ears 7.

A ring 8 of india-rubber or any other elastic material is placed between theparts 3 and 4' in order to insure an air-tight joint. Thetop part 3 includes achamber 9, separated from the chamber 5 by anelastic diaphragm 10, normally kept in a horizontal position by a screw-cap 11, which exerts its pressure on aring 12, which in turn bears on the edge of the diaphragm.

y ln asleeve 13, screwed into the top of thecap 11, slides apiece 14, which can be forced in by pressure on the upper button 15, whereby the piece 14v is caused to descend and to carry with it thebutton 16, which presses on .thediaphragm 10, which in turn depresses thebutton 17, which is on a stem passing through the opening in the valve-casing at when no pressure is exerted on the button 15. v

Carbonic acid can thus be allowed to escape from thecartridge 2 very gradually into the water or liquid.

When it is wished to discharge the whole of the carbonic acid from the `cartridge into water or liquid, the valve 1S can be lowered so that the cartridge can be completely emptied without the necessity for the operator to keep the pressure on the button 15. In this case instead of the button 15 being pressed it must be turned, for which purpose (see more particularly Fig. 3) thepiece 14 is provided with a cross-piece which engages in a crossslot in thepart 13, so that when rotated it carries with it thesaid part 13, which. therefore screws down into thehead 11, and thebutton 16 presses on thediaphragm 10, which in turnpresses on thebutton 17 to open thevalve 18, which can thus be allowed to remain open until the carbonic acid has escaped from thecartridge 2, when the button 15 can be screwed back and the parts resume their normal position.

To prevent danger from too sudden a discharge of the contents of thecartridge 2, I provide a chamber 22 with asmall hole 23, such chamber containing a safety-valve 24, normally pressed to its seat by aspring 25. This valve controls achannel 26, communieating with the interior of the siphon.

When the internal pressure exceeds the limit to which the spring is set, the valve 24 is pressed from its seat and the excess of gas escapes through thehole 23 until the normal pressure is restablished, when the spring 25v closes the valve 24:. l do not limit myseltl to the precise details illustrated.

Having now particularly described and as- IOO certained the nature of my said invention and in what manner the same is to be performed, I declare that what I claim is l. An apparatus for charging liquids with gas, consisting of acartridge or gas-container an outlet-valve for the gas closed by interior pressure, a stem entering said container, its outer end lying in a chamber containing the cartridge and a movable slide entering a screw-cap for said chamber and supported `directly over said stem by an elastic diaphragm which separates the interior of the screw-cap from said chamber, substantially as described.

2. An apparatus for charging liquids with carbonic-acid gas consisting of a cartridge or compressed-gas container inelosedin a chamber, an outlet-valve for said container closed by interior pressure of said gas, a stem entering the cartridge and having one end on said valve, the other end being on the outside, a threaded sleeve tapped into a screwcap, which closes the cartridge-containing chamber a slide arranged to move in said sleeve an elastic diaphragm between the slide andthe stem of the outlet-valve, and a cross-head on VICTOR DURAFORT.
