My invention hasreference torec'eptacles for liquids and particularly to' means for.

siphoning the liquids therefrom.

' It is a purposeof my invention'to provide 5 a siphoning device capable of association 1 with various forms of'liquid'receptacles by which the withdrawalof -liqi iid'; from; a'

The lower endrof :the tubeis formed with notches" 25 which serve to maintain the tube 1 end openi even when resting on the -b'ottom"7 of a receptacle so as to insure the sagejof water intofthetube.

upper end of alcoil ed contractile spring '32 is hooked over-the upper end of theitubing 29, itsll ower end being likewise hooked to i .0 the upper' 'end of a, valve 'stemj 33Ecarrying *a conical shaped valve 34L; formed of rubber v or other suitablematerial, andaclaptedjinlits elevated position to close thelower fend of "the tuloe29.- To insurea tight seat. fort -the .95 it valve; the edge'of the lower end of the V 1 tubing is "taperedpr gbev-ele'd as indicated" at '35. The stem 33: constitutes part of a single length of wire which is benti'atits point of c0nnectionwith-the lower end of: 106 1 the stem to form a horizontal portion 36 which forms a support for a disk shaped washer 37. The washer 37- is designed to form a relatively large seat for the valve 34 so as to prevent cutting of the rubber of which the valve is formed. From the horizontal portion 36 the wirev is extended upwardly to provide a vertical portion 38 which terminates in the lateral extension 39, the extension being doubled back upon itself and extended to form a closed loop 40" of sufhcient diameter to be freelysl dable upon the tubing '29. 7

The extension 39, constitutes, an. operating either of a pair of lips 41 to retain the valve in open position against the closlng action of the spring 32. The lips 41'are formedby inturning ends of a bifurcated extension '42 2 formed at the lower end of a vertical ex- 42 is bifurcatedfor the purpose of receiving [the vertical portion 38 of the valve supporting frame and in a marine-into secure the frame against rotative movement on 1 the tubing, yet allowing'suflicientdateral niovef 'ment of the'extension 39 to engage beneath thelips .41 in latchingthe valve in open position. It will, of course, be understood that movement of the valve 34 to open position is against the tensionjof the spring 32, and consequently when the extension .39 is vided with acord K by which it can be suspended froma support S suchias a nail.

'The bag B is providedwith the usualspout '1 adapted to be closed by a stopper. in the applied position of the siphon device, thestopper C is removed-to permit extension of: the tubing'2l into the bag and to allow the stopper 18 to seat within the spout and thus close the latter.

The long arm l6, the tubing 21, and the pipe 22 all coact to formthe short'leg of the siphon device, while the short arm 17, the tubing 27, and the pipe 29 coact to form the long leg of the siphon. Vhth the short ;leg within the bag B and the long leg disposed exteriorly of the bag, the siphon device'is operable in the following manner:

Assuming that 'the' bag is filled with water, water can be ejected from the bag through the device by first, opening the valve 34 and then compressing the'bag to exclude a r from the siphon device when'the siphon action will be initiated. Water entering thepipe 22 is filtered by the screen 24, and

the water discharging from the pipe 29 can be received in a cup or other suitable receptacle as will be understood, the flexibility of the tubing 27 permitting the pipe 29 to be moved to any desired position.

In operating the siphon device the groove l9vadmits air to the bagto utilize its pressure in continuing the siphoning operation EOHtinue. Upon closing the valve the water discharge is discontinued as will be under- ;stood, and by virtue of the fact that the arm adapted'to'be gripped in moving the valve 34 to open position and to engage valve is urged to closed position, the possibility. of accidental ejection of water from the bag is prevented.

It will be appreciated that by means of my siphon device water can be ejected from the bag while thelatter is in vertical position thus eliminating the necessity of tilting the bag. 'The water discharged from the bag is withdrawn from the bottom where the water is the coolest, the tube 22, by. reason of its'weight retaining the suction end of the tubing at thebottom of the baggf Although I' -have' ,herein" shown and described only one form of siphon device embodying my invention, it is to be understood that various changesv and modifica tions maybe made herein without departing from the spirit of the invention and the spirit and scope of the appended claims.
