SANITARY DRINKING-FOUNTAIN.

Specification of Letters Patent.

Patented Jan. 9, 1912.

Application filed March 28, 1911. Serial No. 617,477.

To all whom it may concern:

Be it known that we, PHILIP MUELLER and ANTON C. SOHUERMANN, citizens of the United States, residing at Decatur, in the county of Macon and State of Illinois, have invented new and useful Improvements in Sanitary Drinking-Fountains, of which the following is a specification.

This invention relates to drinlfing foun tains, and has for its main object to produce a drinking fountain that is thoroughly sanitary and may be installed in schools, public buildings, hospitals and other places where it can be attachedto a regular drinkingfountain bowl, to a special faucet, or to anyother suitable service fitting; suitable means being provided for catching the overfiow water.

The basic principle of this invention con sists of a circular outwardly flowing sheet of water, which may be directed either upwardlyor downwardly, from the center of which sheet of water a small bubbling or upwardly flowing stream of water, for drinking purposes, is projected. This principle is put into practical use by providing a nozzle having a nipple through the center of which the drinking stream flows and around which the circular sheet makes its exit through a separate outlet in the nozzle. Water for the drinking stream and for the circular sheet is received through a single pipe entering one end of the nozzle and flows through separate passageways to the outlets, a regulating means being provided in each passageway for adjusting the force, quantity, and speed ofthe water, each regulating means being independently adjustable. lVhen the flow of water through the fountain is properly regulated the drinking stream will rise sufiiciently high above the circular sheet to enable a person to drink from the top thereof without interfering with the surrounding sheet of water, but should he permit his lips to approach the nipple his face or nose will be filled with water from said circular sheet and cause him to quickly withdraw from the fountain.

With these objects in view, the invention consists of a novel construction, combination and arrangement of parts hereinafter described and pointed out in the claims,

and illustrated in the accompanying drawings, in which Figure 1 is a vertical central section through the improved nozzle which forms the basis of the present invention, Fig. 2 is a side elevation of the several parts which go to form the nozzle, said parts being disassembled, Fig. 3 is a top plan view of Fig. 1, Fig. 4 is a sectional view of a detail of the invention, Fig. 5 is a side elevation of a modified form of the improved nozzle.

Similar reference characters are used to indicate the same parts in all of the figures. In the drawings, the numeral 1 indicates the body of the nozzle, preferably circular in cross-section and held in upright position when in use. In the upper half, more or less, the body 1 is of less diameter than the lower half and comprises two parts 2 and 3, connected by a neck 4:, an annular groove 5 separating the two parts exterior of the neck. The lower part 2 is threaded to receive a shell 6. The upper part 3 is made frusto-conical as shown. H

A threaded opening :7 is formed in the underside of the body 1 into which is screwed an inlet pipe or other fixture,

through which water is conveyed to the nozzle. From the opening 7 a passageway 8 extends into the body for a short distance and isconnected by a cross port'9 with a central bore 10 extending downwardly from the top of the body 1 as far as said port. A second passageway 11 is made through the body 1 from the threaded opening 7 to the annular groove 5. The flow of water through the passageways 8 and 11 is controlled and regulated by separate means of any suitable type, such as screw plugs 12 and 13, the form'erbeing applied from ing communicating with the interior of the shell through which opening projects a nipple 14 threaded on. its lower end to engage the threaded upper end of the bore 10 in the body 1. The lower end of the shell 6 is formed with an interiorly threaded opening to engage the part 2 of the body and fit tightly against a shoulder 15 on the body as shown. The nipple 14 has a spreading head 16, the under surface of which may be inwardly curved in cross-section as shown, or otherwise formed for a purpose to be hereinafter described. The nipple has a central bore 17 through which flows the drinking stream, said bore extending only to the bottom of the nipple,but not quite through it. A small hole 18 connects the bore 17 with the bore 10 in the body 1. Lateral slots 19 are cut in the bottom of the nipple and, if desired, a number of small holes 20 made in the sides thereof a short distance above said notches through which .6 through which the nipple 1 1 passes is slightly larger than said nipple, thereby leaving a narrow annular space 22 through which water from the passageway 11 makes its exit to form a circular sheet surrounding the nipple.

In the form of device shown in Figs. 1 and 2 the lower end of the body is provided with a polygonal collar or flange 23 to fit a wrench or other tool by means of which the nozzle may be held firmly or rotated when attached to the inlet pipe or other fitting. In Fig. 5 the collar or flange 23 is placed just below the shoulder 15 and the lower half of the body lengthened to permit a cylindrical shield 24 being screwed thereon for the purpose of covering and protecting the outer ends of the screw plugs 12 and 13 from malicious or mischievous interference by unauthorized parties.

Water entering the nozzle through the opening 7 from a pipe or fitting device flows upwardly through the passageways 8 and 11. That which enters the passageway 8 runs through the port 9 into the bore 10 and thence up through the holes 18 and 20 into the bore 17 of the nipple and thence upward to form the drinking stream, the height of which is regulated by turning the screw plug 12. The water which enters the passageway 11 flows upwardly through the body into the groove 5 and strikes the under surface of the frusto-conical part 3, there it is deflected laterally and its force-reduced. After filling the space within the lower part of the shell the water passes through the narrow channel between the part 2 and the inner surface of the shell to the annular opening 22 emerging through said opening in a thin annular stream which, striking against the under side of the flaring head 16 of the. nipple, is causedto spread outwardly in a thin circular sheet. This sheet will be deflected outwardly in a horizontal plane or inclined above or below said planeas the shape or conformation of the under surface of the nipple head directs, the object being to produce an unbroken circular sheet sufiiciently near the plane of thetop of the nozzle to enter the face of a person who attempts to place his lips upon the nipple While drinking. The head of the nipple is thin. The protecting sheet of water may be horizontal or even deflected downwardly, but if the head is made thick it will be advisable to cause the sheet to rise above the plane of its emergence from the nozzle at an angle thereto.
