Jan. 29, 1957 w. D. TEN EYCK EASY START TWO-WAY SIPHON Filed Jan. 27, 1956 FIG. 3.
IIIIIIIIJ IEIIII I A I I Illl In FIG. 2.
TEN EYCK WM. DEAN United tts This invention relates to siphons, and more particularly to a novel twoway siphon.
Heretofore, in attempting to remove liquid fuel from a tank whi h may not be conveniently lifted for pouring, such as in the case of a vehicle, the person wouid employ a handmade siphon which consisted of a flexible conduit which would be introduced into the gasoline tank, for example, and the person would merely suck on the said conduit until. the siphon was initiated. Unless one was particularly adept in this procedure, he would often obtain a mouthful of gasoline.
it is the primary object of the present invention to provide a novel type of two-way siphon construction which will overcome this danger and which will provide a convenient and expeditious means whereby fuel may be withdrawn from a vehicle tank and temporarily stored in a suitable container for use, for example, in the internal combustion engine of a lawnmower. i
It is the object of the present invention to provide a flexible container having a closed top and a conduit projecting down through the said top and into the container whereby manual squeezing of the said container will create the desired increased or decreased pressure condition within the said container for automatically initiating the siphon, depending upon the resiliency of the said container.
, it is the further object of the present invention to provide a novel two-way siphon assembly and incorporating a resilient liquid container whereby, for withdrawing liquid from a tank, the said container is manually squeezed together with the air inlet open, after which the conduit is introduced into the liquid in the tank, after which the said air inlet is closed and the inherent resillency of the container is such that in returning to its initial shape, a decreased pressure condition is created Within the said container for automatically init 'ng the siphon for filling said container.
It is the further object of the present invention to utilize the said siphon construction also for effecting an automatic initiation of such siphon in withdrawing liquid from said container. in this case, with the air inlet initially closed, squeezing to ether of the side walls of the said container will temporarily increase the air pressure within the container to thus initiate the action of the siphon for withdrawing liquid therefrom.
It is the still further object of the present invention to provide a two-Way siphon construction wherein the container is non-flexible and wherein there is provided an air vent pipe within the top portion of the said container so that by using the mouth, either a reduced or increased pressure condition within the container may be created for automatically initiating the siphon.
These and other objects will be seen from the following specification and claims in conjunction with the appended drawing, in which:
Fig. 1 is an elevational view of the present two-way siphon with its conduit introduced within a fuel tank fragmentarily shown in dotted lines.
merely a pref Fig. 2 is an elevational view of the same two-way siphon with its flexible conduit introduced within a container sought to be filled with liquid from the siphon container.
Fig. 3 is an elevational section of the container closure for the siphon and wherein the standpipe and air-vent pipe are formed integrally therewith.
it will be u derstood that the above drawing illustrates red embodiment of the invention and that other embodiments are contemplated within the scope of the claims hereafter set forth.
Referring to the drawing, the present two-way siphon includes the upright flexible and resilient liquid container it. having an annular outlet 12st its upper end. A suitable closure disc to having an annular peripheral sealing flange 13 is mounted over said outlet axially of said container with the said flange l3 sealingly engaging the outlet for tightly closing said container.
in the preferred embodiment of the present invention said sealing disc M is secured in position by a cap 15 which is centrally apertured at in and is adapted to cooperatively receive the central elevated portion of the said disc id, a illustrated in Pig. 2. To complete the there 1' provided a suitable flexible gasket 31 Within said cover which normally registers with disc flange and outlet 32 so that upon threaded tightening of the cap the outlet of container 11, the interior of d 5 on be tightly sealed from the exterior, excei't for Z-iCl'l of the air vent pipe 26, hereafter described.
As shown in F 3, and in the preferred embodiment,
the e is for 16d a part of disc 14, which may be of a plastic conmruction, an elongated upright standpipe 17 which projects through the said disc with its lower end spaced above the be*" rn of the container as at 18. The upper end of said i6 ipe extends above said disc as at 19 providing a attachment as at 20 of one end of the preferably flexible conduit 21. The dimensions of the interior of said conduit are such that said end portion 253 tightly and frictionally engages the projecting portion 19 of said standpipe.
The end of said conduit as at 22 is immersed within the liquid such. as gasoline 25 within the tank 24 having outl t which tank and outlet are shown in dcttec lines and tragmentarily, for illustration.
The disc construction is completed by the air vent pipe as which, in the preferred embodiment, is integral with said disc to provide air communication when desired with the interio of container ll.
Pg. 2 an iliustration of the same siphon construction wherein the quantity of fuel stored within container 11 is to be siphoned out and into a tank 27, such as the tank for power l:.v vnmower? There is shown in dotted lines such a tank with inletZh into which the free one 22 of conduit is projected. In the operation hereafter described, the fluid 239 within container 11 will be transferred into container 27 to accumulate as at 30.
As is well known, in the conventional operation of any siphon, in Fig. l, the outlet 13 of standpipe 17 must be below the level of liquid 25 within container 24. Likewise, to operate the siphon of Fig. 2, the outlet of conduit '22 must be beiow the level of liquid 29 within con: trainer ll. i
Container ill be of a flexible plastic construction of polyethylene, for example, or on the other hand, may be a conventional glass container of standard shape such as used for home canning purposes.
The tube 21 may be of rubber or of a plastic material.
The short tube 26 may be of metal, glass or plastic.

arrests be made separately and projected into the said disc in an obvious manner.
The operation of the siphon is in accordance with Pascals Law.
Operation Considering the container 11 to be of a flexible plastic construction, and referring to Fig. 1, to initiate the siphon, the plastic jar is manually squeezed to thus reduce its internal volume temporarily. Thereafter the finger is placed over the air inlet 26 with the lower end 22 of conduit 21 projected into the fluid 25, Fig. The container is now released and the jar, due to its resiliency, will return to its normal shape. By maintaining the air inlet closed, there is produced a reduced pressure condition within said container which draws liquid through the conduit 21 from tank 24, thus initiating the how oi said liquid through said conduit and through the said standpipe 17 for filling container 11. lust as soon as the siphon has been initiated, the finger may be removed from removed from air inlet 26 after the siphon is initiated.
Alternately, if container 11 is non-flexible and made of glass, the siphon is initiated in Fig. l by application of a suction such as by the mouth to air vent pipe 26 to thus initiate the siphon. The present construction positively prevents any of such liquid entering the users mouth.
In Fig. 2 the container 11 is easily emptied merely by temporarily applying pressure by the mouth to the air vent pipe 26 until the siphon is initiated.
Having described my invention, reference should now be had to the claims which follow:
1. A two-way siphon comprising an upright flexible resilient liquid container having an annular outlet, a closure disc having an annular sealing flange positioned tightly over said outlet and secured thereto, a standpipe extending through said disc with one end spaced above the container bottom and with its other end projecting above the disc, there being an air inlet in said disc, and a conduit joined at one end to the projecting portion of said standpipe, manual compression of the walls of said contamer with successive temporary closure of said air inlet and with the free end of said conduit immersed in a body of liquid above the level of any liquid in said conminer and subsequent release of said Walls permitting their return to shape initiating said siphon to fill the container, such compression with the air inlet temporarily closed and with the outlet of said conduit below the liquid in said container initiating said siphon to empty said container.
2. The two-way siphon of claim 1, said disc and standpipe being an integral unit, and a centrally apertured cap receiving said disc and tightly secured over said flange and outlet.
