Specification of Letters Patent.

Patented .Tune 16, 1908.y

Application filed. August 5, 1907. Serial No. 387,227.

To all whom 'tt may concern:

Be it known that 1, DEwIs LANDAU, a citizen of the United States, residing at San Francisco, in the county of San Francisco and State of California, have invented new and useful Improvements in Siphons, of which the following is a specification.

This invention relates to improvements in siphons or other receptacles for dispensing liquidssunder pressure, the object of the invention being to provide simple and convenient means for reducing the air pressure of such receptacles, so as to cause the liquids to flow therefrom with less violence, and also to permit the receptacle to be completely emptied of liquid while maintaining a suitable pressure therein.

1n the accompanying drawing, the figure is a vertical section of the device.

Referring to the drawing, 1 indicates the body of a siphon bottle, and 2 is the head thereof, formed with a dispensing spout 3 and a finger lever 14 connected to the usual valve, not shown, for controlling the passage of the liquid through said spout, and with a charging spout Ll, adapted to be connected with a suitable charging apparatus such as that shown in my patent U. S. Letters Patent No. 816,985, dated April 3rd, 1906. This bottle is intended to be used in an inverted position, so that the dispensing spout extends downwardly therefrom when so inverted. Through the head 2 passes loosely a glass tube 5 connected to a sleeve 6 havin(T a flange 7, and around said sleeve is a rub er gasket S. Said iiange 7 is in contact with a cap 9 having an internal thread by means of which it is screwed upon the threaded end of the head 2 of the Siphon, the'gasket 8 being interposedbetween theflange 7 and the edge of said threaded end, so that the sleeve 6 is contained within said threaded end, spaced therefrom, the tube 5 extending therethrough into the center of the body of the siphon bottle. Said cap has formed therein a conduit 10 leading from the side to the center and then upwards and connected with the interior of the sleeve 6 and of the glass tube 5, and said conduit is controlled at the side by means of a needle valve 11. The cap is formed with a downward extension or plug 12 adapted to rest in a socket in a suitable stand 13, or, if desired, the siphon can be supported by the charging apparatus and attached thereto by thecharging inlet.

The siphon bottle may be charged in any desired manner, and when it is found that the pressure of the air in the siphon is too great, the needle valve is opened slightly to permit a sufficient amount of air to flow from the siphon, while at the same time drawing the liquid therefrom by the dispensing spout.

1t has heretofore been the practice to charge siphon bottles at a very high pressure, from 150 to 180 pounds. This practice is very dangerous, and numerous accidents have occurred therefrom. The pressure hasbeen so high in order to insure dispensing all the liquid contained in the bottle, for if a lower pressure were used a quantity of the liquid would be left in the siphon. 1n the present apparatus no such high pressure is needed, for the siphon can be filled from time to time from the charging apparatus, the liquid being maintained therein at a suitable pressure. And when lthe liquid is discharged at too high a pressure, resulting for instance, when dispensing beer in the formation of an excessive quantity of foam, the pressure can be readily reduced to just that magnitude that will allow the beer to escape without violence and with only a moderate quantity of foam. It will also be observed that, with this arrangement, however the pressure is reduced in the siphon bottle, the liquid will still continue to flow therefrom, on account of the inverted position of the bottle. No vacuum can be created in the siphon which would prevent the flow of the liquid, because it is possible at all times to admit air to the upper part of the Siphon. My improved device therefore provides means both for reducing the pressure to prevent the liquid flowing out with violence, and also for increasing the pressure, when desiring to prevent the formation of a vacuum in the bottle which would arrest the outflow of the'liquid. It will readily be understood that by closing the needle valve, after drawing liquid from the siphon at the same time the discharge valve is closed, the pressure in the siphon can be maintained the same, until the neXt occasion of use of the Siphon `and thus there will always remain sufficient pressure in the siphon to aerate the liquid and discharge the same.

The needle valve 11, comprising, with its seat, self contained means for holding the valve at any desired position of adjustment, permits the air passage to be opened to let air in more or less freely, as may be desired,

and to remain open to that extent, without any further attention on the part of the operator, while dispensing from the receptacle liquid sufficient to lill a number of glasses in succession. Furthermore, said valve is located at a distance from the controlling mechanism of the liquid discharge spout, so that said controlling mechanism can be` so operated to completely open the liquid discharge spout, without opening the air passage. In fact, said air passage may be controlled entirely independently of the liquidcontrolling means.

I claim 1. A siphon bottle having a discharge spout discharging downwardly when the bottle is inverted, means for controlling the passage of the liquid through said discharge spout, a tube in said bottle leading from its bottom when so inverted to a point near its top, and an air controlling valve for controlling the passage of air in said tube, said valve and its seat being provided with selfcontained means arranged to retain the valve at any desired position of adjustment for any desired size of said passage, and the spout-controlling means being arranged remote from said valve, to permit said controlling means to be fully operated independently of said valve, substantially as described.

2. A siphon bottle comprising a body portion, a head having a charging inlet and a discharge spout, the latter extending in a said cap and head, a gasket for making a tight joint therebetween, a tube connected with said sleeve and extending to a point near the other end of the bottle, Asaid cap having a conduit leading fron an external point to said sleeve, and a valve controlling said conduit, substantially as described.

3. A siphon bottle comprising a body portion, a head having a charging yinlet anda discharge spout, the latter extending in a downward direction when the bottle is inverted, a cap closing said head, a sleeve having a flange adapted to be clamped between said cap and head, a gasket for making a tight joint therebetween, a tube connected withsaid sleeve and extending to a point near the other end of the bottle, said cap having a conduit leading from an external point to said sleeve, said cap having a plug adapted to rest in a suitable socket in a stand to support the bottle in an-inverted position, and a valve controlling said conduit, substantially as described.

In testimony whereoiI I have hereunto set my hand in the witnesses.
