mam. e1.221* -15 This invention relates to faucets, and particularly to one intended for use on a liquid container from which the liquid is intended to be.

dispensed by inversion of the container. Distilled water, for instance, is commonly distributed to individual usersin containers intended to be so used; a crock having a faucet therein being usually supplied to the user, the crock supporting the container in an inverted position. It is one of the objects of my invention to pro vlde a dispensingfaucet adapted to be removably and directly applied to the neck of the container,

so that the need of a crock or similar vessel is unnecessary. l

A further object of my invention is to provide a faucet for the purpose which admits air to the container as the liquid is withdrawn therefrom in such a manner that an even andsmooth inflow of air without bucking the liquid is obtained, insuring an even flow-of liquid from the contaner. j

, A further object of the invention is to produce a simple and inexpensive device and yet one which willnbe exceedingly effectivefor the purpose for which it is designed.

These objects I accomplish by means 0:5 such 1 structure and relative arrangement ofparts as will fully appear by a perusalof, the, following specification and claimspl M I In the drawing similarchara'cters of reference indicate corresponding parts in the several views 2 Figure '1 is a sectional elevation of the faucet v connected to the neck of a bottle, the faucetbeing closed.

Referring now more particularly to the characters of reference on the drawing, and describ-' ing the, faucet as in its normal or depending position relative to the container, the faucet vcomprises a liquid outlet tube I depending from an enlarged flange 2. This flange is substantially the diameter of theneck 3' of the bottle 4 or other container to which thejfaucet is intended to be applied.- A resilient washer'5 is disposed between a the flange and the rim of the neck, the flange being clamped against the 'washerfl to give a liquidtight fit by means ofa screw cap-or ring nut member 6 adapted to engage the threads I provided'on the neckl i I Projecting into the neck from the. flange 2 in clearance relation to said neck is anopen ended .tube'8. This is concentric with tube l, and somewhat larger in diameter. flange is another tube 9, which practically an Figure 2 is a similariview, showing thefaucet ing the. same,

Depending from theextension of tube, 8, and which surrounds the tube I in concentric and clearance relation thereto. This tube 9 is somewhat shorter than tube I, and is provided about its lower edge with a resilient ring gasket l0. Air bleed holes ll extend through the flange so as to lead from between the tubes I and 9 to the outside of tube 8, the number of these holes being such as to provide 'an air intake areasuflicient to compensatefor the ,1

amount of liquidwithdrawn from the outlet tube I. Y a

Normally engaging the gasket It! in sealing relation is'a cupped closure disc I 2, formed, with a central depression I3 to receive the projecting vided at the top with an outwardly'projecting flange- I1 which slidably engages a skirt l8 formed and depending from the cap 6. A compressionspring 19 is disposed about the member l6 inside skirtl8, andJat its ends engagesthe flange H andan inwardly'projecting flange 20 on'the lower edge of the skirt and which also guidesjthe member "5. Theflanges l1 andHZU from exteriorally of, the faucet to the space be- .tweenjmembers l6 and 9. I a

the disc, is attached "to; a tubular member l6 which-extends about tubev9 in a clearance relation thereto and which is proare both notched or otherwise cut away at me tervals so' asto provide for a' free flow of air In operation, the spring normally acts to hold v the valve discagainst the gasket I), thus pre'-.

venting any air from gaining access to the '-c'ontainerv andof course preventing liquid from leav When the' nozzle. is pulled" down, agate the resistance of the spring, the valve disc is lowered fromv engagement with the gasket. Air canthen enterthe container 4 from'th'e outside, passing down" between members 9',and 5,. under the gasket, and then up between the tubes. I and 9 and into the container on the outside of tube 8 through passages l l. Theincoming air of course allows the liquid ,to flow from the faucetthroughtubes 8 and I, over the valve disc and through passages l5 to the, nozzle, outlet.

thernozzle being thus interrupted, a smoother Thedirect downward flow of the liquid from- A v and softer flow from the nozzle is obtained, without any loss of volume.

Due to the fact that the liquid outlet tube l terminates below the air intake tube 9, and that the highest point of the valve disc (over which the liquid must flow) is below the closure gasket when the faucet is open, the outgoing liquid on the disc does not interfere with the flow of air in the opposite direction into the tube 9.

Due to the large size of the liquid outlet tubes 8 and I relative to the air intake holes ll, practically all the liquid takes the path of least resistance and passes down through said tubes rather than through the holes. air intake space between the tubes I and 9 relatively empty of liquid, so that the desired inrush of air into the container through said holes is" unrestricted. Also, since the air enters the container clear of the ,path of the main body of downwardly flowing liquid, such liquid offers no interference to the intake of air. As a result, a liquid flow of substantially constant volume is obtained.

As will be particularly clear from Fig. 2, the flange 2 of the tube unit is clamped in place. by the removable cap or nut 6. Removalof this nut therefore enables the tube unit to be withdrawn from the remaining parts of the faucet assembly. This facilitates sterilizing operations, as well as making it very easy to replace the gasket Ill Whenever necessary.

From the foregoing description it will be readily seen that I have produced such a device as substantially fulfills the objects of the invention as set forth herein.

While this specification sets forth in detail the present and preferred construction of the device, still in practice suchdeviations from such detail may be resorted to as do not form a departure from the spirit of the invention, as defined by the appended claims.
