DRINKING-FOUNTAIN.

Specification of Letters Patent.

Patented Dec. 17, 1912.

Application filed August 14, 1911. Serial No. 643,891.

1 0 all whom it may concern:

Be it known that I, JOHN HALL, J12, a citizen of the United States of America, residing at est Springfield, in the county of Hampden and State of Massachusetts, have invented new and useful Improvements in Drinking-Fountains, of which the following is a specification.

This invention relates to a drinking fountain and is an improvement over the class of drinking fountains which is coming into wide use in public places as a means for avoiding the use of public drinking cups.

The fountain is arranged so that a person may take a drink therefrom in the most convenient manner possible.

The principal object of the invention is to provide a fountain of the character referred to which is convenient for use.

of a fountain of the character referred to.

Other objects will appear from the detailed description and the claims annexed thereto.

Referring to the drawings,--Figure 1 is a plan view of the fountain assembled. Fig. 2 is a vertical sectional view taken through the center of the apparatus, showing the parts in their proper working order.

Referring to the drawings, a indicates a ring mounted upon the main casting b, which main casting is arranged as shown with the central opening M leading from a cored out portion of the casting d as is clearly apparent from the drawing. The lower end of the main casting is formed into a hollow cylindrical portion which is adapt-ed to receive a pipe element 9. Fig. 2 shows the pipe element 9 inserted in the hollow cylindrical portion. This element is closed at its upper portion except for a hole which has a rim around its bottom as shown. A valve h is adapted as shown to cooperate with this rim and close the opening f in a manner to be described. The valve has a slotted head and its stem eX- tends up through the hole j which is considerably larger in diameter than the valve stem. The head of the valve is provided with a washer held firmly against the head by a'suitable nut or retaining member. The valve stem screws into a centrally threaded hole in the main casting, as clearly shown in Fig. 2. The pipe element is adapted to be screwed into a pipe fitting suitable for connection with any desired water supply of the usual pressure. The main casting Z) fits over the pipe element- 9 and slides freely thereon with rather a tight lit. The normal position of the parts is with the valve 70 closing the opening f, as will later be described.

Into the same centrally threaded hole in which the valve stem screws, a non-squirting device C is screwed. This device is formed as shown with a rounded upper end with slots cut at right angles, as is clear Another object is to simplify the structure from the drawing. A consideration of the drawlng and applicants necessary operation hereln described will make it clear that under normal conditions of operation the water surges into the chamber d around the surface thereof and is directed down against the cone-shaped piece 0. At this point it is met by water which has passed over the same course and which is being pressed out through the annular opening formed by member 0 in the hole m. This meeting of the two forces tends to push water out of the annular opening in a suitable bubble without any tendency to squirt. The slots in member 0 allow the annular stream of water to work toward the center of the bubble to make the drinking stream solid. These holes also tend to prevent children from playfully squirting water from the fountain. If the finger or hand is held over the outlet it can not cover a material part of the outlet area because of the member c and the water shut off at one part of the outlet area has a chance to pass across through the slots in c to that part of the area which is left open and thereby be evenly distributed over that area. The greater part of this device when screwed in the hole, is located within the cored out portion (Z. The upper portion of the device forms, in conjunction with the hole m, an annular opening through which the water leaves the cored out portion of the casting. There are small holes connecting the cored out portion cl with the interior of the hollow cylindrical portion of the main casting. These holes may be arranged as desired. It might be desirable to have them connect with the hole f more directly. As shown, they are arranged in two pairs, each pair at right angles to the other.

Fig. 2 shows the parts in the position they occupy when a person is drinking. Ordinarily, however, the pressure of the water supply will act on the bottom of the valve head and on the surface is, the outlet through the holes 6 being restricted, of the main casting, to lift said main casting, which will carry the washer on the valve head against the rim and close the passage f. After this is done, the water pressure will act on valve head It to maintain the washer against the rim. In this operation it is seen that it takes more force to lift the main casting to close the valve, than it does to maintain the valve closed when once lifted. This is due to the inertia of the mass.

By the use of applicants apparatus as arranged, the water pressure when lifting the casting acts on the surface provided by the valve head and also on the surface 70 of the casting. These two lifting surfaces, with a very moderate pressure, are sufficient to allow the valve to close and when the valve is once closed, the same moderate pressure of water will keep it closed, acting only on the valve head h,because of the difference of pressure required in the two instances. This is an important feature of applicants invention, because by means of it, applicants fountain can successfully operate with water pressures far below what it otherwise would require.

One of the principal features of applicants fountain is the means by which squirting is absolutely prevented and a smooth bubble of the right height can be had without any possibility of squirting. The means by which this is done will now be described. The water (assuming the parts to be as in Fig. 2) enters by pipe element 9 up the opening f, works into small holes 6 and enters the cored out chamber d. The peculiar conformation of this chamber 03, together with the device a and opening m, is the principal means by which the most desirable kind of a bubble can be obtained. The device 0 can be screwed up or down, to regulate the passage by which the water enters the chamber cZ. As the water leaves the holes 6, it strikes the horizontal bottom of the device 0 and is deflected sidcwise as it enters chamber (1. The bottom wall of this chamber, although shown horizontal, might be inclined upwardly or scooped downwardly to start the water coming in a horizontal direction into chamber 03 into a circular motion. The form of chamber shown will do this, but other forms will also, and it is not desired to limit the invention to the particular form shown. The surface of the chamber on the sides and upper part is more or less circular in form. The water will rush against this circular surface and follow it first upwardly and then downwardly. The surface adjacent the opening 17?. being inclined downwardly, considering the direction which the water will travel. With this chamber as shown, the water will surge into the chamber and leave it by the annular opening shown, without the possibility of squirting.

Applicant has found by making a device exactly as shown and described, that no matter how high a water pressure the fountain is connected with, it will not squirt in the least. This seems to be due to the fact that the water leaves the chamber through the opening m in an annular form, the downwardly inclined surface of the chamber adjacent the opening forces water in a downwardly direction and this water opposes any direct rush of water out of the annular opening around the non-squirting device 0. The slots in the latter seem to allow the water forming the drinking bubble, to be more nearly solid than it otherwise would be. The height of the bubble can be regulated by screwing 0 up or down as desired, as is clear from the drawing.

The operation is as follows: A person desiring to drink holds the face over the ring a and presses down on the handles provided. The ring prevents the lips from coming in contact with the nozzle. This downward pressure will open the valve h and the parts will be in the position shown in Fig. 2. The apparatus is self-closing, that is, the water pressure will act to close the valve without any action of the operator, except- 1ng the release of the initial pressure. This closing operation has already been described. It can be seen that less pressure is required to open the fountain that it is desired to provide for closing it; for on opening the valve the water pressure on the surface of the head It only needs to be overcome. The parts are few, and a fountain of the kind described is easy to manufacture and low in cost.
