DRINKING-FOUNTAIN.

Specification of Letters Patent.

Patented May 16, 1911.

Application filed May 5, 1910. Serial No. 559,470. i

The object of the invention is to provide a drinking fountain of the nature referred to which is simple and eiiicient, and capable of ready application for use.

A further object is to provide means in a device of the nature referred to for equalizing the pressure and flow of water supplied to and through the drinking cup of the device.

V the arrows. Fig. 3-is a detached detail view A further obj-.ct is to provide means for eificiently draining the drinking cup and its fitting.

Other objects of the invention will appear more fully hereinafter.

The invention consists substantially in the construction, combination, location and relative arrangement 'ofparts, all as willbe more fully hereinafter set forth, as shown in the accompanying drawing and finally pointed out in the appended claims.

In the drawing :Figure 1 is a view in top plan of a drinking fountain constructed in accordance with the principles of our invention. Fig. 2 is a view in vertical, central, longitudinal section of the same, on the line 2, 2, Fig. 1, looking in the direction of in perspective of a slotted and bored plug forming a tortuous passage for the water passing through the device. Fig. 4 is a similar view of the cap nut for securing the capable of being readily and easily attached to any ordinary water supply pipe, and wherein the drinking cup need not be touched when required for use, and is constantlv kept fresh and cleans free from germs and efficiently drained.

In carrying out our invention we provide a short section of tube having at one end means for securing the same to a water supply pipe, and a stop cook or valve for opening and closing the same to the water supply, the other end of said tube having a drinking cup attache... thereto in such relation that the water passing through the tube delivers upwardly into and through the cup centrally from the bottom thereof.

In the drawing, reference letter A designates the short tube, B the fitting at one end thereof for attaching the same to a water supply pipe. In the form shown, the

end of the tube is threaded and a correspondingly threaded socket in the fitting B, screws thereon. A plug valve or stop cook, the handle of which is shown at-C, and which may be of-the usual, ordinary or any well known construction is associated with the fitting B. The other end of tube A is arranged to extend into a drinking cup D, centrally through the bottom thereof, the cup D, being clamped or held in place in any suitable or convenient manner, as, for instance, by the screw nut E, and cap nut F,

' threaded upon the end of tube A, the bottom of the cup being clamped between these nuts. In practice we prefer to so bend or shape the tube A, that when attached to a water supply pipe the end thereof which extends into the drinking cup is vertical thereby supporting the drinking cup with its upper edge in substantially horizontal and level position. To accomplish this resalt in a simple manner the tubeA maybe bent in to the familiar curvature of a pipe stem, the drinking cup D corresponding to the pipe bowl, although, instead of the tube A communicating with the interior of the drinking cup through an opening in the side thereof, as is customary with pipes, the tube delivers into the drinking cup centrally through the bottom thereof.

Usually the pressure in water supply pipes is subjected to more or less variation. In the use of a drinking fountain of the class to which our invention relates it is desirable to equalize the pressure andflow of water into and through the drinking cup. In order to accomplish this result, in accordance wlth the principles of our invention, we provide means to cause the current of water to react upon itself as it flows through the tube A, whereby a substantially uniform flow of the water into and through the drinking cup is secured. This result nally through a portion of the length there of, and terminating in a laterally disposed slit of opening J, cut into the side of the plug near one end thereof, thereby presenting a flat wall transversely the length of the longitudinal hole or passage H, the end of the plug in which the slit or cut J is made being tapered, as shown. \Vith -this ar rangement it will be seen that the current of water flowing through the fitting It, when the stop cock therein is opened, will pass through the bore H, of plug G, and, encountering the flat transverse surface of the solid end wall of the lateral slit or cut J,

- will react upon itself and flow out laterally through said slit or cut and around the tapered end of the plug into the enlarged bore of the tube A, and through the bottom thereof. The tortuous passage thus provided as a means for causing the current of water to react upon itself, presents a constricted passage which terminates against a transverse flat solid wall with an abrupt lateral opening from the constricted passage into the enlarged area of the bore of tube A,

ithereby efiiciently equalizingthe pressure of the water and securing a uniform current iiow into and through the drinking cup. Thus the cup is held. 1n an upright position with its upper edge level. The water entering the cup from a point centrally of the bottom thereof rises evenly and gently in a column through the body of water in the cup, instead of Spurting up in a jet, forming an evenly rounded hill, so to speak, in the center of the water in the cup, finally overflowing the rim of the cup all the way around, keeping such rim clean.

If desired, and in order to drain the device when not in use, we provide openings K, through the end of the tube to which the drinking cup is attached, and which afford passages from the bottom of the cup back into the tube. e also provide an opening, indicated at M, in the lowest part of the tube By these means the device is edi- This plug is proeea iae ciently drained when not in use, thereby avoiding the accumulation of dust or germs in the water which'would otherwise remain standing in the cup and tube when the valve cock is shut off. Consequently fresh clean water from the supply pipe is assured at all tunes when the valve is open for the use of the devlce.

Having now set forth the object and nature of our invention, and a construction em' hodyingv the principles thereof, what we claim as new and useful and of our own invention, and desire to secure by Letters Patentis,-
