W. H. ROSE SIPHON DEVICE May 28, 1935.

Filed May 11, 1934 INVEN R /7 v2 ,Z KTTORNEY D S A ES FATE Patented May 28, 1935 sIrnoN Davies William Rose, JerseyCity, N. Application May 11 1934; Serial No'. 725,011?" My invention relates to container closures and refers particularly to closures for containers containing an aerified, or a gasified liquid, the removal of said liquidbeing eifected by the pres sure of said air or gas.

that worn, orinoperative, parts may be replaced.

My invention overcomes all of the above mentioned, and -other disadvantages-and objectionable fea'ture's incident to the present known siphon devices and presents adevice of this character of simple and economic production, not 1ia-' ble to become inoperative, capable of being mad ily and eflectivelyapplied to differentoontainers and in which worn or inoperative parts may be readily and inexpensively replaced.

In my device, I take advantage of thebending of a rubber tube to produce a perfect seal-to prevent the pa'ssage' of liquid therethrough, and have invented means whereby such bending may be readily and. effectively accomplished and released. V V

The device of my invention, its ease of operation and its many advantages over the present employed siphon devices may be readily recognized and appreciated by a consideration of the accompanying drawing in which similar parts are designated by similar numerals.

Figure 2 is a fragmentary vertical cross-section of the device of Figure l in open position.

Figure 3 is a vertical cross-section of a modified form of my device.

Figure 4' is a section through the line 4-4 of Figure 3.

Figure 5 is a fragmentary vertical cross-section of a modified form of my device.

Figure 6 is a fragmentary vertical cross-sec-. tion of a modified form of my device.

'Figure 7 is a fragmentary vertical cross-section of a modified form of my device.

The particular form of the device of my invention illustrated in Figures 1 and 2, comprises a container closure member consisting of the lower element l0 adapted to fit within the neck I! of a container l2, a flange l3 adapted to abut upon the upper face of the neck II, and an upwardly ex- -4Claims. 01.137520).

tended hollow closure element 14, the extension l-5 of whi'chis bent downwardly in its normal position. For purposes of rigidity of construction, Iprefeiyto have the walls of the lower portion' of the element 14 andthe end portion of the element l5 somewhat thickerthan the intermediate walls for reasonsexplained later.

' A rubber tube 16 extends upwardly from the bottom portion of the'contairier l2 through the opening of theelement Hand into and partially through the opening in the element I5. The device is preferably of soft rubber andof such constructionthatfivhen it is in its normal position the angular portionll of the elements l4; l5 will cause thetube Hito be bent and closed and thus preventing the escape of liquid therethrough, while the raising'of the element l5 into the position shown in dotted lines in Figure 1 and in full lines in Figure? willopen the tube l6 at its previously closed position, thus allowing the gas in the container I2 to force the liquid therein outwardly through the tube; It and the open end of the element I5.

' As the 'rubber tube It will expand upwardly when the pressurethereon is released, I provide fora spacebetween it arldthe outer members l4, 16 at IT, and by having the wallsof the outer member thinner at that point than elsewhere, the bending of that member at that point is more positive.

It is evident, therefore, that when the element I0 is insertedwithin the neck of a container containing an aerified, or a gasified liquid, the normal position of the device will prevent the escape of the liquid, and in order to obtain a'portion of said liquid all that is necessary is to raise the element I5, the height to which it is raised governing the rapidity of flow of the liquid, while the release of the element IE will immediately close the device from further liquid exit.

The modified form of my device shown in Figures 3 and 4 consists of a cork, or stopper member Ill through which is passed a tube l8 of hard rubber, metal, glass or other suitable material to which a second tube I9 is pivotally attached by means of thepivotal member 20. A coiled spring 2| is carried by the pivot 20, one end portion 22 of the spring 2! abutting upon the inner face of the tube I8 and the other end' portion 23 of the spring 2| abutting upon the inner face of the tube IS. The springs 2 l', 22, 23 retain the tubular members I 8 and IS in the position shown, thus closing the tube l6 and preventing the exit of liquid. If however, the tube l9 be raised from its normal position, the tube [6 will worm be opened, allowing the exit of liquid from a container to which the device is applied.

The modified form of the device of my invention shown in Figure 5 is similar to that previously explained except that the portion 24 of the device adapted for applying it to a container has an inwardly inclined flange 25 to allow of the attachment to the outer face of the under side tion shown in Figure 7 has a telescopic tube consisting of the elements 32 and 33, to allow of the proper placement of the lower end of the tube 33 with respect to the bottom of the container, a rubber tube 34 being affixed to the upper end of the tube 32.

It will thus be seen that my device is of economic construction, that it is easily and posi tively controlled, that it is of application to various sizes of containers, that the length of the exit tube can be readily changed to meet the requirements of the container bottom, and that its several parts may be readily exchanged and replaced.

It is further evident that the closing of the exit tube by the bending thereof requires considerably less force than would be necessary to close it by external pressure upon a straight portion of the tube and hence, the particular form of bending closure means accomplished by the device of my invention allows of its practical and effective application for the purposes to which my invention is adaptable, and further, the bend-'- ing of the tube producesa perfect seal which is most diiiicult of accomplishment by any external pressure, which is extremely important in a siphon device to prevent the escape of the gas under pressure within the container.

I do not limit myself to the particular sizes, shapes, numbers, arrangements or materials of parts as shown and described, as these are given simply for the purpose of describing the device of my invention.

What I claim is:

1. In a siphon device, in combination, an upwardly extended resilient tubular member capable of attachment to the neck of a container, at second resilient tubular member carried by the upper portion of said first tubular member and angularly movable with respect thereto and a compressible tube within said tubular members, the normal position of said tubular members being such as to effectively bend and close said compressible tube the resiliency of said tubular members returning them to their normal relationship after they'have been moved from said normal relationship.

2. In a siphon device, in combination, an angular resilient tubular member adapted to be attached to the neck of a container and a compressible tube within said tubular member, the normal angle of said member being such as-to ef-v fectively bend and close said compressible tube, and the movement of one portion of said tubular member being such as to open saidtube.

3. In a siphon device, in combination, an angular resilient tubular member adapted to be attached to the neck of a container, the walls in the middle portion of which are thinner than in the end portions thereof-and a compressible tube within said tubular member, the normal angle of said member being such as to efiectively bend and close said compressible tube,'and the movement of one portion of said tubular member being such as to open said tube.

4. In a siphon device, incombination, an angular resilient tubular member adapted to be attached to the neck of a container'and-a com pressible tube within said tubular member, the normal angle of said member being such as to effectively bend and close said compressible tube, and the movement of one portion of said tubular 'member being such as to open said tube, the resiliency'of said tubular members returning them to their normal relationship after they have been moved from said normal relationship.
