UNITED STATES JOHN J. nnanaen, or anrarnrs, 'rnnunssnn SIPHON A1311) SUPPGRTING MEANS FOR THE SAME.

Application filedFebruary 28, 1923. 'SerialNo. 621,378.

l7 '0 all whom it may concern I Be it known that 1,5 OIIN; J. DARRAGH, a citizen or" the United States, residing; at Memphis, in the county of Shelby and State of Tennessee, have invented certain new and useful Improvements in Siphonsand Supporting Means for the Same, of which the following is a specification.

The present invention relates tosiphons adapted to beused on water bottles, as supplied filled to ofi'ices, dwellings, and consumers in general. These siphons are provided with means for supporting them adjustably on bottles of different sizes, or on other containers holding liquids, Whether such containers are open or closed.

Such water bottles are delivered filled with drinking water and the usual manner of using them is to invert the bottle in a stand after removing the stopper, the bottle being gradually emptied by drawing water from a faucet on the stand or cooler.

As these bottles are comparatively large, holding about five gallons of water and with practically smooth sides, they are very difficult to handle, and can hardly be inverted without spilling some of the water. They sometimes slip from the operators hands, while being handled and are smashed on the floor, causing the loss of both water and.

bottle, not to mention damage to carpets and Sometimes the person handling these containers is severely cut by their breaking and there is also danger of injuries by strains caused by the direct lifting of such heavy containers.

In order to avoid such accidents,-thepresent invention aims at emptying thebottle or container when in an upright position, after it has been placed on a suitable stand or a table, which emptying can be done gradually as the water or other liquid is required during the day. s

In the accompanying drawing one embodiment of the invention is illustrated, and- Figure 1 is a vertical section of a water bottle with the siphon in position; and

Figure 2 is a perspective View of the attachment for the siphon.

In the drawing,reference numeral 10 represents a bottle of the usual kind for delivering Water to households and oflices, and this bottle is placed on a suitable stand 11 in the usual manner.

The neck of the bottle is filled with a cork or stopper-12, through which extends a short tube or, vent 13 of glass or metal for admitting aininto the bottle. This tube, Which may be straight or, as seen in the drawing, L-shaped, extends with its lower end 141a little below the inner end of stopper 12, while its outer or. upper end 15, which may be bent at right angles to the portion in the stopper, terminates outside of the latter and may bethreaded as at 16 to receive an air pump. WVhen the siphon is used in open containers no stopper is needed, it being possible to use the siphon in open containers by pouring liquid in the siphon while holding it upside down, then placing the siphon in the container, when the liquid in the siphon will cause the liquid in the container to be drained. l The siphon proper 17 consists of astraight inner leg or pipe section 18te'rn1inating near the bottom of the bottle and held in position by the stopper 12, through which it extends and is 'bent as at 19 at right angles continuing downwardly to form an outer leg or pipe section 20, which may follow the contour of the bottle if the latter is of standard size and shape, as seen in Figure 1, or if used for other bottles. or open containers, the siphon'may be, of 'U-shape. e V

The lower end of the outer leg 20 is provided with a valve 21, from which extends, below the bottom .ofthe bottle, a nozzle 22. This valve 21 is preferably situated below the lower end of the. inner leg 18 in order to dirainthe bottle completely. By means of this valve a column of water is always retained between each individual draining, so that whenever-the valve is opened this column is ready to raise and draw more water out of the bottle or container.

In order to secure the siphon on the bottle, a bandorfhoop 230imetal wire or any other suitablematerial is coiled as at 24;, once or twice around the outer leg 20, and this hoop ,is made of a size suitable to embrace the bottle 10. It isevident that if flexible material is used for this hoop and the ends v made to overlap each other, the hoop may be expanded to fit difierent size bottles, thus making the device adjustable.

The siphon 17 may be made of glass, rubber, metallic tubing or other suitable material and the inner and outer legs 18 and 20 may be made in one piece or connected by a flexible transverse portion 19 if so desired. It the two legs are made of separate straight pieces of tubing, they may be connected to a straight cross piece by elbows to facilitate cleaning.

The use of the siphon is not limited to water, but it may be applied to bottles or other containers holding liquid such as oil, vinegar, cider or the like. After the bottle has been placed in an upright position on the stand 11, its cork is replaced by the stopper 12, carrying the siphon 17 together with the air tube or vent 13, and the hoop 23 slipped over the bottle so as to hold the outer leg 20 tightly against the same. By the use of a small air compressor, such as a bicycle pump or the like on the threaded end 19 of the air tube or vent 13, the air above the water level in the bottle is compressed until the water runs out at the nozzle 22, when the faucet or valve 21 is open. In this manner a column of water is forced through the inner leg 18 and into the outer leg 20, so that both of them are filled and the faucet or valve 21 is thereupon closed and the air pump removed from the air tube or vent 18. Directly this is done, the .air above the water will have atmospheric pressur but when the faucet or valve 21 is again opened, the higher column of water in the outer leg 20 will raise the water from the bottle through the inner leg 18, so that water will run out through the nozzle 22. As the interior of the bottle connects with the atmosphere, any quantity drawn will be replaced by air through the tube or vent 13. Preferably a small check valve 26 is inserted in this tube or vent 13 so as to prevent dust and foreign particles from getting into the container. This is a one way valve, which may be closed by a light hair spring, so that it will remain shut until the water is being drawn, when the air from the outside will open this valve against the reduced pressure in the bottle caused by the withdrawing of the water.

The utility of this device is evident, as distributors of distilled water and mineral water are aware of the reluctance of oonsumers to use the large, heavy and cumbersome containers, in which the distilled or mineral waters-are generally delivered, for the reason that it is very dihicult to invert the bottles and place them on the stand or receptacle. Accordingly people do not buy distilled or mineral waters in such quantities as would otherwise be the case. By'the use of the siphon, with the flow of water controlled by a valve, forming the subject matter of the present invention, the invertin of the bottles is'entirely avoided and the bottles are drained easily in small or large quantities as may be needed.

It will be evident that the flow of water or other liquid from the bottle or cistern is entirely under the control of the valve 21, because, whenever thisvalve is closed, a column of water will remain in the siphon, which column is ready to lift and draw water from the container into a glass or receptacle whenever the valve is again opened.

One advantage of the use of this siphon beside that of not having to invert the bottle when placing it on a stand is, that the siphon is not easily broken, particularly if made of a non-corrosive material such as block tin pipe, and does not get out of order. The water coming directly from the bottle instead of having to pass through any intermediary receptacle, would be sure not to be contaminated in any way, as no dust from the outside of the bottle can pass into the water.

Having thus described the invention what is claimed as new is:

The combination with a liquid receptacle having a reduced neck defining a shouldered portion, a stopper fitted in the neck of the receptacle, a relatively short vent tube extending through the stopper and having one end thereof communicating with the interior of the receptacle and its other end provided with means for communication with a source of air supply, a siphon including an inner leg passing through the stopper and extending to a point near the lower end of the receptacle and an outer leg connected therewith and bent to conform to and resting on the shouldered portion of the receptacle, the lower end of the outer leg of the siphon being offset and extended down wardly, a valve secured to the lower end of the outer leg and provided with a discharge nozzle, and a supporting band encircling the receptacle and provided with a loop through which the outer leg of the siphon extends near its said ofiset portion for holding said outer leg in contact with the shouldered portion of the receptacle.

In testimony whereof I affix my signature.

JOHN J. DARRAGH. [Ls]
