SELF-CLOSING- FAUCE'I.

Application filed .l'une 9,

To all whom it may concern.

Be it known that I, THEODORE H. SCHUTT,

a citizen of the United "States, residing at ,This invention relates to I self-closing faucets, such asare used for drawing off water or. other liqulds into a drinklng glass or other receptacle. The inventlon has particular relation to that class of faucets in which the controlling valve is actuated by .the recetacle to be filled.

One 0 ject of the invention is to provide .aself-closing faucet the operating mechanism for which is engaged for actuation by theside instead of by the rim or edge of 1 I 8 15 through a nozzle 16 threaded into the the.drinkingglass or receptacle, so that the device is sanitary and there is no danger of contaminating a succeeding receptacle from deposits on the operatingfmecl'ianism from a preceding receptacle.

A further object of the invention is to provide simple valve mechanism which avoids the use of springs and may also dispense with packings, and which is simple to construct, inexpensive to manufacture, and is not liable to get out of order in service.

Further objects of the invention are in part obvious and in part will appear more in detail hereinafter.

The invention comprises the construction and arrangement of parts hereinafter described and claimed.

In the drawings, which represent one embodiment of the invention, Fig. l is a side elevation; Fig. 2 is a sectional elevation on the line 2-2, Fig. 1; and Fig. 8 is a sectional elevation on the line 38, Fig. 2.

The device shown in the drawings comprises a suitable hollow fitting adapted for connection to the reservoir or the device from which the liquid is to be withdrawn. This reservoir may be a tank, water cooler, or other device (not shown), or the valve. may be connected directly to a service line. As illustrated the fitting is provided with the usual shoulder 2 to seat against the outside of the reservoir and a threaded connection 3 for entering an opening in said reservoir. At its opposite end the fitting is externally threaded to receive the threaded 1919. Seria-1N0. 302,840.

end 1 of the faucet body 5-, which is of *hollow form with a cross-wall 6 thereindividing the cavity in the body into ajpressure chamber 7 communicating with the supply fitting and a dischargei'chamber 8. A portion of the wall 6. is horizontal as shown ,in s

portion of said stem slides in apocket 13 ina capl l fitted to the top of. the valve body, while the lower endof thestem-15 extends through-the port or opening 9 and serves as a pushrod for opening the' valve.

The outlet from the discharge chamber bottom of thegvalve body and'having-a vertically extendingiopening 17 to direct the stream downward y.

At one side the valve 'body is enlarged, as at 18, said enlarged portion being hollowed out to form therein an extension 19 of the discharge chamber 8. The enlargement 18 is also pierced horizontally through the chamber extension 19, and in the opening thus formed is located a shaft 20. The inner end portion of said shaft rests in a pocket or recess 21 of the valve body and. is non-circular in cross section. such as by being provided with a flattened portion 22, to receive the eye 23 of a lever lying in the chamber extension 19 and having an arm 2 1 extending beneath the push rod 15. The outer end of the shaft 20 extends through an adjacent wall of the casing or body. At the opposite end of the enlargement 18 the body is provided with a trunnion of substantially the same diameter as the shaft 20, and which, for example, may be a screw 25 threaded into an opening in the casing or body and whose head is of cylindrical form.

The valve mechanism is operated by a lever 26 bifurcated at its upper end to form a yoke comprising two arms 27 each of which has an eye at its upper end. The eye of one of said arms turns on the trunnion 25, while the eye of the other arm is secured to turn with and actuate shaft 20, such as by being secured to said shaft by a screw 28. The lower end of said lever extends forwardly and is preferably provided with a engagement of said arm with a. fixed part of the casing, such as with the nozzle 17, as indicated at 30. In drawing water from the faucet the drinking vessel, such as a glass, is held in the hand and pushed into position beneath the outlet portion 17 as shown in the dotted lines, Fig. 3. This motion pushes back the arm 29 and turns the lever 26 in a counter-clockwise direction, thereby turning shaft 20 and lifting the valve 9 from its seat. The drinking vessel does not touch the valve mechanism or body except at its side and some distance away from its rim,

.so that it cannot be contaminated. When the drinking vessel is withdrawn the lever 26 returns to its original position by gravity and the valve is closed by the supply pressure.

No packing is necessary around the shaft 20, which passes through the discharge chamber and not through the pressure chamber. However, if desired, said shaft at one or both ends may be packed to prevent entrance of air to the discharge chamber such as might break up the otherwise solid discharge stream. As illustrated the opening in which the shaft turns is closed at one end by the screw 25, whose head is provided. with a shoulder which can be turned up tight against the outside of the casing. At its other end the shaft may be provided with a packing 31 compressed by a nut 32 surrounding said shaft and threaded into the casing.

What I claim is:

A self-closing faucet, comprising a casing provided with pressure and discharge chambers, a valve controlling the flow of liquid from the pressure to the discharge chamber, a shaft rotatable in the casing and having a portion lying in the discharge chamber and operatively associated with said valve, a yoke member for engagement by the side wall of a receptacle, one arm of said yoke member being fixedly mounted on one end of said shaft, the other end of said shaft having rotatable bearing in the wall of said casing, and a trunnion fixed in the wall of said casing and affording bearing for the other arm of said yoke member.

In testimony whereof I affix my signature in presence of two witnesses as follows:

THEODORE H. SCHUTT.
