Specification of Letters Patent.
Patented Feb. 3; 1920.
Application filed December 27, 1918. Serial I To. 268,451.
To all trim/a it may concern:
- Be it known that I, WINFIELD E. HINS- DALE, a citizen of the United States, residing at Trenton, in the county of Mercer and State of New Jersey, have invented certain new and useful Improvements in Drinking Fountains, of which the following is a specification.
This invention pertains to drinking fountains, and has for its main object the pro duction of a structure which while simple is at once sanitary and meets the requirements of modern practice.
It is essential, in order to produce a sanitary structure, that the. stream of water issuing from the fountain should not in any wise be contaminated, and to this end it is likewise essential that the nozzle from which the jet or stream passes should be so arranged that the stream itself cannot fall back upon the nozzle, and further that no droppings from the mouth of the user can fall back upon the nozzle or be carried back thereon by the stream issuing from the nozzle. It has been demonstrated that where a stream issuing from a nozzle falls back upon th nozzle that an unsanitary condition obtains and that injurious bacteria are not only present upon the nozzle surface but are likewise ever present at the apex of the stream. It is, therefore, essential that the stream should not fall back upon itself and it is likewise essential that a structure should be provided which will preclude the user placing his lips in contact with the nozzle from which the jet issues.
To that end I have devised a structure wherein the jet issues at an angle and does not fall back upon itself and wherein means is provided for washing the section of the structure adjacent the point of issuance of the drinking jet, or, in other words, that section which is immediately adjacent and surrounding the nozzle from which the jet issues. The structure is likewise so formed that the bowl is washed over its entire surface and the wash water is carried outwardly through the drain without in any wise coming in contact with the discharge face or surface of the nozzle.
One mbodiment of the invention is shown in the annexed drawings wherein the fountain is of the pedestal type, though it is to be understood that the invention is in no wise limited to this type and may be employed in conjunction with wall fountains having rectangular bowls or bowls of other shapes, as will be readily appreciated by those skilled in the art.
In the drawings,
Figure l is a vertical sectional view of a fountain of the pedestal type;
Fig. 2 an enlarged sectional view of the upper or bowl portion of the fountain; and F ig. 3 a top plan view partly in section.
In the drawings, 1 denotes the pedestal carrying a bowl 2 at its upper end. The bowl is provided with a central discharge outlet 3 which is preferably screened. 4 denotes the supply pipe which in the form illustrated is provided with a lateral fitting 5, to which is attached the usual control cock or valve 6, the opposite discharge branch of which is connected by an expansion coupling 7 in the lower end of a cham her or recess 8 formed in the body ofthe structure. A port or channel 9 extends from the chamber 8 and terminates in a nozzle 10, the port standing at an angle to the vertical and inclining inwardly toward the center of the bowl. As will be noted, the nozzle projects upwardly beyond the contiguous face or surface of the bowl so that any water passing over such surface will not flow overthe to a of the nozzle but will pass down and arounfl each side of the same to the central discharge opening 3. A second port or channel 11 extends upwardly from the chamber 8 and opens into a horizontally disposed rim channel 12 from which extend a series of perforations or openings 13. The water which passes from the openings 13 runs down the adjacent bowl surface and about the nozzle, washing such surface, and thence passes to the central discharge opening 3.
Preferably a control stop or shut-0E 14: will be provided in the line 4, said shut-off being employed to control the volume of flow which passes through thesupply pipe, and is, of course, not under the [control of the user, being adjusted by the party who instals the fountain or one charged with its upkeep. lVhile the orifices or openings 13 are shown as only partially extending around the rim of the bowl, it is conceivable that they maybe formed entirely around the bowl, if such arrangement is deemed adinvention is not limited to the showing wherein the openings 13 are present along one side only. It is found, however, in practice, that a protective water screen of sufficient size or area will be formed by the jet openings placed as herein shown and described.
It is also to be noted that by having the nozzle 10 raised somewhat above the interior surface of the bowl as small a surface as possible is produced about the nozzle so that there is nolikelihood of any lodgment of deleterious matter or substance thereabout.
In operation the volume of water is initially set or controlled by the cook or valve 14 and the user simply opens the usual stop cock 6 which permits the water to be ejected from the nozzle, the jet passing upwardly and falling back in a parabola, striking against the opposite side of the bowl. Water will also issue from openings 13 and pass down as indicated in Fig. 1 over the adjacent bowl surface, about and around the nozzle. The user will place his mouth about the stream issuing from the nozzle and any water falling back from his mouth, or waste matter falling into the bowl while he is in the act of drinking, will fall into the running water issuing from the flushing rim and will consequently be immediately washed into the waste pipe, thus preventing the soiling of the interior of the bowl adj acent the nozzle. The water issuing from the flushing rim also prevents a person resting his hands on this portion of the bowl while the water is flowing therefrom. It likewise precludes the possibility of the user putting his mouth down to and in contact with the china nozzle as from whatever point the nozzle is approached its position in the bowl will bring some part of the users face into direct contact with the flushing water. Again, the present invention prevents maliciousness or playing with the stream, as any attempt to squirt water by any method of stopping the nozzle will only increase the volume of water passing through the flushin rim openings which will run off through the bowl waste. The number of openings in the rim are too many to materially increase the flow through the nozzle.
From the foregoing it will be readily seen that the drinking fountain will always deliver water uncontaminated by any condition which might exist about the fountain head and in a manner approved by health and research boards, as well as in a manner that makes for ease in a persons use of the fountain.
What is claimed is:
l. A drinking fountain comprising a bow] having an inclined jet aperture and means for projecting a flowing screen of water over the surface of the bowl adjacent and surrounding the jet aperture aforesaid.
2. A drinking fountain comprising in combination a bowl having an inclined jet aperture located at one side thereof and a plurality of jet openings located at the upper portion of the bowl and adapted to project a flaring screen of water over the surface of the bowl adjacent and about the jet aperture.
3. A drinking fountain comprising in combination a bowl, a nozzle located in one side thereof and having an inclined jet opening formed therein; a water channel formed in the rim of the bowl; and a plurality of jet openings extending therefrom in a direction to project a flaring screen of water over the surface of the bowl adjacent and about the jet aperture.
4. In a drinking fountain, the combination of a bowl; an inclined jet aperture formed in one side thereof; and a plurality of jet openings formed in the upper portion of the bowl above said jet aperture, said openings being relatively small as compared to the diameter of the jet orifice whereby a water screen will be formed which will flow over the adjacent and surrounding surfaces of the jet orifice but not in contact with the issuing angular jet.
5. In a drinking fountain, the combination of a bowl having a hollow rim with perforations closely spaced extending into the rim from the inner face thereof and communicating with the space in the rim; a nozzle located in one side of the bowl at a point below said perforations, said nozzle being provided with an inclined aperture adapted to project a stream of water upwardly at an angle above the plane of the hollow rim; and means for supplying water to the said rim and to the nozzle.
6. In a drinking fountain, the combination of a bowl having a hollow rim and a series of perforations closely spaced in the mm and communicating with the water chamber therein, a nozzle located at one side of the bowl below the rim and adapted to project a stream of water at an angle above the plane of the rim, said nozzle being located below the perforations aforesaid; and means for supplying water to said hollow rim and the nozzle.
7. In a drinking fountain, the combination of a bowl having a hollow rim; a se-.
ries of perforations opening from the inner face of the bowl into said rim; a nozzle located in one side of the bowl and projecting upwardly beyond the contiguous inner face thereof, said nozzle having an inclined jet aperture formed therein; a chamber located beneath the aperture, said chamber likewise communicating with the perforations afore said; and means for supplying water under pressure to said chamber.
8. A drinking fountain of vitreous china,
comprising an integral bowl having an in clined jet aperture and means for projecting a flowing screen of Water over the surface of the bowl adjacent to and surrounding the jet aperture aforesaid.
9. A drinking fountain formed of a unitary piece of vitreous china, comprising in combination a bowl having an inclined jet aperture located at one side thereof and a plurality of jet openings located at the upper portion of the boWl and adapted to project a flowing screen of Water over the surface of the bowl adjacent and about the jet aperture.
In testiinony'whereof I have signed my name to this specification.
