, DRINKING-FOUNTAIN.

Specification of Letters Patent.

Application filed iranuar 7, 1918. Serial No. 210,626.

To all whom it may concern:

Be it known that I, PETER 'W. BLAIR, a citizen of the United States, residin at Quincy, in the county of Norfolk and gtate of Massachusetts, have invented a new and useful Drinking-Fountain, of which the following is a specification.

My invention relates to improvements in drinking fountains of the type known as sanitary, and more especially to nozzles for such fountains, and consists of a certain peculiar nozzle attachable within the bowl of a fountain of the said type, together with such connections and other parts and members as may be necessary or desirable in order to render the device complete, serviceable, and eflicient, all as hereinafter set forth. 7 v

The primary object of my invention s to provide, for a sanitary drinking fountain, a nozzle which throws astream of water at an angle to the perpendicular, or projects such stream laterally away from the discharge or'ifice, outlet, or mouth of said nozzle, instead of straight upward, to the end that the normal drinking point is remote from the vertical plane of said outlet, and no water that has touched the lips of a person drinking can come into contact with said outlet.

A further object is to provide a nozzle, such as I have just outlined,- which can be readily attached to or connected with a drinking-fountain bowl that has the customary central supply opening. V

'Still'another object is to furnish simple and convenient means for connecting such a nozzle with a bowl which. is provided with a nipple in the center of'the bottom thereof.

This nozzle and the elements of the fountain with which it is most intimately connected andv associated are designed to be connected with suitable supply and waste pipes or equivalent members, with which pipes or members are employed the customary pressure regulating and valve-controlling means. p ,7

The fountain equipped with this nozzle is highly efficient as weR as being entirely sanitary.

Other objects and advantages will appear in the course of the following description.

I attain the objects and secure the advanol: n; mrention by the means l-ll'llS- trated in the accompanying drawings, in which Figure 1 is a top plan of a sanitary drinking fountain which embodies a practical form of my invention; Fig. 2, a central, vertical section through said fountain, taken 011 lines 22, looking in the direction of the associated arrow, in Fig. 1, and, Fig. 3, a side elevationof the nozzle detached from the other elements.

Similar numerals refer to similar parts throughout the several views.

In the drawings a drinking-fountain bowl is represented at 1, which bowl is equipped with a nozzle 3, said nozzle having one end located'in the axial center of said bowl and the other end at one side of or beyond said center. The nozzle 3 has an outlet or mouth 4 in the outer end and opening through said end at .the top thereof, the axial center of which mouth is oblique to the axial center of the bowl 1.

The nozzle 3 as shown is an approximately horizontal, hollow member having the oblique mouth 4 at or in the outer terminal and an opening 5 in the bottom at the other terminal. Said nozzle is provided with a sleeve 6 which has an exteriorly screw-threaded part 7 tapped into the opening 5. The sleeve 6 is interiorly screwthreaded and adapted to fit'and engage a nipple 8 that rises from the center of :the bowl 1, and said sleeve has a dome 9 that i The bowl 1 is designed and adapted to be mounted on a supply and waste casing '(not shown), which casing or the supply pipe or equivalent member is provided with the necessary or desirable elements of regulation and control, of'usual and well-known construction and operation. An annular flange 12, on the underside of what maybe termed the base 13 ofthe bowl 1, is provided tofit around the top of the aforesaid casing, upon which latter said base is adapted to're'st, and a central, vertical, screw-threaded, inlet opening 14, in said base, is provided for the upper terminal of the aforesaid supply pipe or equivalent member, which opening or passage continues up through the nipple 8.. The passage or inlet 14 and the continuation of such passage through. the nipple 8 and Patented May at, 1920..

the sleeve 6 and into the dome 9 have a common axis which is in the center of the bowl 1. A waste passage 15, in the base 13, opens at the top through the bottom of the bowl, and at the lower end into the space within the flange 12.

It will now be seen that the supply of water to the fountain enters the passage 1.4-, flowing in the direction indicated by the adjacent arrow, in Fig. 2, and passes through the base 13, nipple 8, and the upper part of the sleeve 6 into the dome 9, out through the opening ll in said dome into the chamber 10 in the nozzle 3, and through said chamber and the month t of said nozzle. It will be seen, further, that, owing to the location and inclination of the mouth 4-, the stream of water, upon leaving said mouth, must continue upwardly and toward the axis of the bowl 1 and beyond such axis until drawn by gravity into said bowl, the pressure of the water being regulated, by the means to which reference has been made, to insure the deflection of said stream to the necessary extent before the water is projected over the edge of the bowl. The oblique direction of the stream of water immediately upon leaving the mouth 4 is indicated by the associated arrow, in Fig. 2. The point at which'the mouth is applied to the stream for the purpose of obtaining a drink is at such a distance from the mouth 4 that no portion of said stream with which-the lips of the person drinking come in contact does or can return to the orifice whence the stream comes.

In practice the stream rises obliquely from the mouth 4 and is projected to a point approximately over the inner, closed end portion of the nozzle 3, which portion is in the center of the bowl, at or a little be yond. which point preferably the mouth of the person desiring to drink is applied. After passing the aforesaid point the stream falls into the bowl at some distance from the outlet of the nozzle or the mouth 4.

The water in the bowl escapes through the passage 15. The velocity or force of the water at and adjacent to the mouth prevents a' person from attempting successfully to drink at that point, and compels such person to take the drink from the stream at a sufiicient distance from the said mouth'to obviate all possibility of contaminatingthe same. In order to drink to the best advantage theperson should interpose the mouth in the path of the stream at approximately the point where said stream begins to change from an upward to a downward course. q It is now clear that germs from the moutl .Of a person canbe deposited on the water outlet portion of the nozzle neither by direct appli:ati on of are lips to such pen tion of said nozzle, or indirectly by the falling back on said nozzle or said portion thereof of the water after contact with said mouth or lips. This fountain is, therefore, entirely sanitary in the particulars herein pointed out, as hereinbefore stated.

The perforated dome 9 protects the interior supply members from foreign substances or matter that might, by accident or design, find the way or be introduced into the nozzle 3, which could occur only while the water was shut off below the passage 14; and said dome also serves as a check on the water or a means to control the flow of the same, in addition to such other means as may be provided for that special purpose.

The nozzle 3 can be unscrewed from the sleeve 6 and the latter from the nipple 8 in the event it becomes necessary to clear or clean out the parts. In this connection attention is called to the facility with which the nozzle of the old type, which has its axis in common with the. axis of the bowl, can be replaced with the new nozzle, it being necessary merely to unscrew the old part or parts. accordingly as only the nozzle proper or both said nozzle and the sleeve must be changed, and screw on the new part or parts. This is an important and valuable feature.

More or less change in the shape, size. construction, or arrangement ofsome or all of the parts of this fountain may be made without departure from the spirit of my invention.

I am aware that means in drinking fountains for proiecting a stream or a plurality of streams of water horizontally or obliquely have been used before,and do not therefore. seek to claim such means broadly.

What I claim as my invention, and desire to secure by Letters Patent, is

1. As an improved article of manufacture,

'a drinking-fountain nozzle comprising a horizontal member having therein bottom and top openings at opposite ends, respectively, and a longitudinal passage with the bottom of which at one end said bottom opening communicates, and with the top of which at the other end'said top opening communicates, a separable inlet sleeve at tached to said. member ,and extending through said bottom opening, and having a perforated dome within said member and communicating with said passage, the major axis of said -member being approximately at right-angles to the axis of said sleeve, and the axis of said top opening being oblique to the axis of said sleeve.

2. The combination, in a drinking fountain, with a bowl having a central vertical inlet, of an approximately horizontal nozzle having an inlet in the bottom adjacent to one end. and attached at such endfo said bowl over said first-named inlet, said nozzle extending laterally from the axis of said first-named inlet, having in the top adjacent to the other end an outlet the axis of which is oblique to said first-named axis, also having a communicating passage between the inlet and outlet therein, and being an integral member which has therein said bot tom inlet adjacent to one end, said top outlet adjacent to the other end, and said con1- municating passage between said inlet and outlet.

3. The combination, in a drinking fountain, with a bowl provided in the bottomwith a central nipple, and having a vertical inlet opening through said nipple, of a removable sleeve mounted on said nipple, said sleeve having a perforated dome, and an approximately horizontal nozzle mounted on and removable from said sleeve over said dome, extending laterally therefrom, and having in the outer terminal an outlet the axis of which is oblique to the axis common to said nipple and sleeve, the connection between said sleeve and nozzle being in the bottom adjacent to one end of said nozzle.
