SAMUEL DAVIS, OF NEW YORK, N. Y.

\ SIPHON OR VESSEL FOR AERATED LIQUIDS.

SPECIFICATION formingpart of Letters Patent No. 534,552, dated February 19, 1895 Application filed July 5, 1894. Serial No 616,643. (No model.)

To all whom it may concern:

of the United States, residing at New York,

in the county and State of New York, have invented newand useful Improvements in Siphons or Vessels for Aerated Liquids, of which the following is a specification.

- The object of this invention is to provide a siphon or vessel by which aerated liquids,-carbonated beverages and the like can be readily generated and the invention resides in the novel features of construction set forth in the following specification and claims and illus trated in the annexed drawings, in Which Figure 1 is a sectional elevation of the'vessel. Fig. 2 is an inverted plan view of Fig. 1. Fig. 4 is a sectional detail view of a modification.

The side or wall 1 of the bottle or vessel has a bottom 2, the side 1 extending down below this bottom to form agas generating chamber comprising three compartments, the compartment 3 being for the reception of a chemical or powder and the compartment 4 for water or a generating liquid, so that when the chemical and generating liquid mingle in the lower space of the gas generating chamber which forms a mixing compartment 5, carbonic acid is generated. The bottom 6 of the gas generating chamber has an opening 7 and the bottom 2 has a screw threaded opening 8. The cover 9 has a screw threaded stem 10 which when screwed into opening 8 will close the latter, While cover or main part 9 closes the opening 7, the openings 7 and 8 being superimposed as seen.

To generate an aerated beverage the cover 9 is removed and the vessel turned upside down. The liquid to be charged is then filled into the bottle space 11 through opening 8, the chemical and generating liquid are placed into their respective compartments 3 and 4 and the cover9 replaced, the stem 10 screwing into opening 8 so that noliquid from bottle space 11 can escape through opening 8 when the bottle is set upright. On the bottle being set upright the chemical and generatingliquid mingle in the lower or mixing compartment 5, the mixing if desired being accelerated by shaking the bottle, and the gas or pressure generated will enter from the gas generatingchamber into the bottle space through conduit12 having a valve or closure 13 allowing Be it known that I, SAMUEL DAVIS, a citizen pressure to enter from conduit 12 into the bottle space but preventing said pressure passing back from the bottle space into the conduit.

.To prevent the generated gas or pressure from causing leakage between bottom 6 and cover 9, said bottom 6 is made yielding as for example by being made of suitably thin or elastic or corrugated material so that the generated pressure will tend to bulge the bottom stem 10. Instead of being made contractingthe bottom 2 may be of any other suitable shape.

Instead of employing a washer or packing 14 as in Fig. 1 the edges of opening 7 and of cover 9 may be suitably inclined or ground to fit one another (Fig. 4) so that the outward bulging of bottom 6 will tend to effect a firm closure between said bottom and the rigidly held cover 9.

The contents in the bottle space 11 can be drawn off by a tube or siphon 15 having spout 16 and valve 17 or by any other suitable arrangement.

The cover 9 can be readily screwed to and from its place by a ridge or handle 18 suitably placed on said cover.

Of course the use of the device is not confined to making aerated beverages, since the space 11 could be variously charged as for example with fire annihilating substance so that the device could be used as a fire extinguisher.

Supposing the vessel space 11 when the device is inverted to have been filled through opening 8 to its full capacity. Then on the insertionof the screw stem 10 if the latter were closed or solid no space would be left in the vessel space 11 for the proper entrance of gas or pressure from the gas generator. By making the screw stem 10 hollow as seen in Fig. 1, some of the liquid in space 11 will run down into the hollow stem 10 when the device nished' by the hollow or space in stem 10 will' lessen the liability of the device bursting.

As the compartments 3 and 4t communicate with one another only through the mixing compartment 5 and respectively hold the chemical and generating liquid out of active contact while the device is reversed or upside down, the cover can be firmly secured in place before by setting the device upright the chemical and generating liquid are mixed to generate gas, so that loss of gas or pressure while the cover is being put in place can be avoided.

The chemical and generating liquid may be of any suitable well known kind as for example bicarbonate of soda and acid or acidulated water or other suitable substances, as a dry mixture of bicarbonate of soda and tartaric acid to be placed in compartment 3 and Water to be placed in compartment 4. The generating substances for generating gas ,or pressure can readily be selected by those skilled in the art.

What I claim as new, and desire to secure by Letters Patent, is-

1. Avessel for aerated liquids provided with a gas generating chamber made to communicate with the vessel, said chamber having a bottom or wallprovided with an opening, and a cover for said opening, said bottom being made yielding so as to be forced against the cover by the generated pressure substantially as described.-

2. A vessel for aerated liquids provided with a gas generating chamber made to communicate with the vessel, said chamber having a bottom or wall provided with an opening and a cover for said opening, said cover being secured or connected to the vessel and said chamber bottom being made yielding so as to be forced against the cover by the generated pressure, substantially as described.

3. A vessel for aerated liquids provided with a gas generating chamber made to communicate with the vessel, said chamber having a bottom or Wall provided with an opening and a cover for said opening, said cover being provided with a gasket or washer seated in the cover, and said bottom being made yielding so as to be forced against the washer by the generated pressure substantially as described.

4:. A vessel for aerated liquids having a rigid bottom 2 provided with ascrew-threaded opening, a chemical chamber 3, a mixing chamber 4, a gas generating chamber 5 arranged below said rigid bottom and provided with an opening, a cover 9 closing the opening in the gas generating chamber and pro vided with a screw-threaded stem which directly engages the screw-threaded opening in the said rigid bottom, and a conduit 12 opening through the said rigid bottom at one side of the screw-threaded opening therein for placing the interior of the vessel in communication with the gas generating chamber,

substantially as described.

5. A vessel for aerated liquids, having a rigid bottom 2,provided with a screw-threaded opening, a chemical chamber 3, a mixing chamber 4:, a gas generating chamber 5 arranged below said rigid bottom and provided with an opening, a cover 9 closing the opening of the gas generating chamber and provided with a tubular screw-threaded stem which directly engages the screw-threaded opening of said rigid bottom, and a conduit 12 opening through the rigid bottom at one side of the screw-threaded opening therein for placing the interior of the vessel in com munication with the gas generating chamber, substantially as described.

In testimony whereof I have hereunto set my hand in the presence of two subscribing witnesses.

SAMUEL DAVIS.
