BUBBLING DRINKING-FOUNTAIN.

To-aZZ whomz't mag concern: v f

Be-itknown that I, SIMEoN C. KEITH J r'.,

of So'merville, in the county of Midd esex and Stateof Massachusetts, have invented certain new and useful Improvements in.

Bubbling Drinking-Fountains, of which the following "is a specification.

This invention has relation to drinking fountains, such as are used ig se hoolsaud otherpublic places, in which the water bubbles or is discharged upward in a short stream from a nozzle, "so thata person assuaging his thirst'may put his lips directly to the nozzle and drink the water as it emerges therefrom. Such fountains fulfil all requirements in preventing the spread of contagious or infectious diseases, inasmuch as the stream of water, so far as is known, washes away any germs or microbes which may be left by the person last drinking, and for this reason such fountains have been widely adopted.

In the practical use ot such fountains,

however, a ditficulty has arisen, and this in rooms are not in use, and hence at recess,-

when the water-closets require a practically constant flow of water and the fountains are most in demand, the bubble or jet is reduced to its minimum. On the other hand, were the 'height of the bubble or jet fixed when all the other fixtures were being used and water being delivered thereto, the pressure in the fountains at normal periods would be so great that the jet or bubble would be too strong and rise to a too great height.

As stated, theobject of the present invention is to provide such drinking fountains with means for regulating the water pressure so that the height of the bubble or jet will remain constant at all times. To this end I provide a bubbling fountain head,

which may be attached to the end of a service pipe and which is self-contained and se f;

forma jet or bubble, and between said nozzle or opening and an inlet portthe head is provided with an -,instru mentality which so controls the passage of the water 'to the nozzle that, the waterdelivered to the latter is ata'constant pressure irrespective of the pressure in the service pipe.

' On the accompanying drawings, I have illustrated two different embodiments of the invention, and doubtless others will suggest themselves to persons skilled in the art towhom this disclosure is made.

. Figure l ofthe drawing illustrates a bubbling drinking fountain provided with my invention. Fig. 2- represents a vertical sectional view, full size, of another embodiment of the invention. Fig. 3 represents'a horizontal section on the line 3'3of Fig. 2.

Fig. 4; represents a similar sectionon th line 4-4 of Fig. 2. Fig. 5 represents a vertical section through the base of the cup and shows the throttling valve removed. Fig. 6 is a perspective view of a piston used in my device. Fig. 7 represents a vertical section through the fountain shown in Fig. 1.

It is quite apparent that the invention may be utilized in various standard drinking fountains which are supported by columns or otherwise.

In Fig. 1, I have illustrated somewhat conventionally a sink consisting of a hollow slab a having a wall plate I). The water which is received in the slab a, is conducted to the sewer through a dischargepipe 0 having the usual trap. d indicates a service pipe through which water is delivered to the nozzle as will be explained.

In the embodiment of the invention shown in Figs. 2 to 6 inclusive, which illustrates a Patented Mar. 5, 1912. Y

the cup and the casing it are separable, yet, a

when connected, they form a single casing,

constitute in one,.instrumentality a bubbling fountain, and inclose the reducing valve to be described. From the interior of the flange there leads a conduit :16 which terminates at its' end in a valvejseat having" a port 17 communicating with a cylindrical' passageway 18.. The conduit and, -ssagea 5 way are formed by an arm19 exten ding inwardlyfrom the cylindrical .wall tjf the cas- .151 spring projects into v a socket 24 with ,which' j a' cap 25," screwed .on the'lower end of the, casing, is;provided. The piston is provided-*;

In the position shownin Fig: 2, the-flow, of water through the port 1:7 isf substant-ially unobstructed byj? the valve rr'ieii ber,. but,v asthe piston moves downward slowl'y5flthe flow of water through the portwill be gradually diminished until 8.0 finally g t cut} oil altogether.

Should the pressure in l thei, servi,ce pipe be increased, the piston will ,7

In both forms of the invention, the casing, with its inclosed' regulating va'lge, is

Consequently each fountain may be substituted for a faucetor terial alteration in the service piping, and will deliver at all times a bubble of substantially unvarying height. Moreover in both forms of the invention, the-nozzle is immovable with respect to the casing, in the sense that itsposition is unchanged byvarying pressures in the service pipe. All exterior or exposed portions of-the head or fitting arezrigid or immov ble while the deeliverin water, the controlling or regulating mec anisms. being all covered or contained within the head.
