ANTIFREEZING DRINKING FOUNTAIN.

Application led November 12, 1919. Serial No. 337,493.

To all whom it may concern:

Be it known that we, PHILIP MUELLER and ANTON C. SCHUERMANN, citizens of the United States, residin at Decatur, in the county of Macon and tate of Illinois, have inventedl new and useful Improvements in Antifreezing Drinking Fountains, of which the following is a specification.

The present invention relates to sanitary drinking fountains and while it is disclosed in connection with a particular type of bubblerhead, pedal-operated supply fountain, it will be understood that the features disclosed and claimed may be applied to other and various types of fountains.

It has for its object to provide -a foun-v tain, in which the drinking supply and waste may be ladequately controlled and taken care of, and in which sanitary conditions are observed, and, furthermore, provides a fountain, which is calculated to withstand low temperatures. without danger of freezing either the supply or waste.

In the drawings herewith is illustrated one embodiment of the invention and in said drawings Figure 1 is a side view of a fountain made in accordance with the invention, parts thereof being in section for clearness of illustration,

Figure 2 is a vertical sectional view on an le)nlarged scale of the bowl, pedestal, and

ase,

Figure 3 is a sectional view cock and its connections,

Figure 4 is a view in elevation'of a supply pipe drain,

Figure 5 is a bottom plan view of the pedestal and its anchoring means,

Figure 6 is a view in section of the pin connection between the pedestal and base,

Figure 7 is a detail view to illustrate the pedestal clamping means,

Figure 8 is a view in section of the lower part of a fountain' similar to that shown in Figure 1 illustrating a different type of operating pedal, y

Figure 9 is a detail view showing the mounting of the pedal lever.

Referring to the drawings by numbers, like numbers indicating like parts in the several views, 10 denotes a base-p1ate, which may be ofthe formshown in plan in Fig) of` the supply 5, which base-plate, as indicated in Figs. l and 2, rests upon the curbing of the well or pit into which portions of the supply and waste depend. The base-plate 10 may be secured in any suitable manner, a convenient way of securing it, where conditions are suitable, being the crossbars l1 and the bolts 12, which passl through apertures in the base plate and clamp said bars and base,- plate tightl to the cover of the well or pit. The" base-p ate is provided also with locating and holding pins 13 designed to engage apertured lugs 14 on the interior of the pedestal 15.

The said base-plate l0 has a central aperture through which passes the lower section of the waste pipe 16, this being held therein by screw 17., the upper end of the wast-e pipe section being threaded in the present disclosure and coupled to the upper section of the waste pipe by the coupling sleeve 18 as shown in Fig. 2. The lower end of the waste pipe 16 will extend into the well or pit to any desired distance and has at its lower end a coupling chamber 19 for sewer Connection, said coupling chamber 19 having preferably formed integral therewith, the radially disposed supply chamber 20,

which connects through the wall of theK chamber 19 with the supply cock 21, the inner end of the supply chamber 20 delivering to the supply pipe 22, which-risesvertically in the waste pipe 16 t-o the bowl and bubbler head presently to be described.

The supply cock is coupled with any suitable supply 23 and is provided with an .automatically closing valve 24, the stem of which passes through a stuiiing nut 25 and is connected at its upper end with a link 26 upon which is secured adjustably a weight 27 as shown, this weight being designed to counterbalance the valve operating parts presently to be described. The valve 24 is preferably provided With a clos- -ing spring 28 (see Fig. 3) sothat when released the valve will, by the spring and weight, automatically close. Mounted in the cock body on the other side ofthe valve seat is a stop and regulator 29 by .means 'of which the ow may be regulated or entirely cut off if desired, as indicated in Fig.' 3.

In order that the supply pipe 22, which will, of course, befllled with water upon cates with the outlet sideof the cock and has therein a springclosed valve 31, the stem l33 of which valve may be eccentrically placed or otherwise formed so as to give free water passage past the valve. The spring 32 surrounding the valvestem bears against a flange on said stem and normally tends to close thevalve. The upper end of the valve stem 33 passes through asuitable stulling nut 34 and said stem is actuated by a finger 35 projecting from the coupling head 36, which lconnects the stem of the valve 24 with the link 26. Vith this arrangement it will be seen that when the valve 24 is opened, the finger 35 will be raised, releasing the stern 33 and the valve 31, which valve will be immediately closed by its spring and the water will pass to the supply chamber 20 and the supply pipe 22. When the valve 24 is closed the linger 35 willforce the stern 33 and valve 31 downwardly against the spring 32 opening the valve and permitting the water to drain into the chamber 30, from which lchamber it passes by the drain pipe 37 to the coupling chamber 19 of the waste pipe, the drain connection 37 being bent as shown in Fig. 3 to form a water seal.

If desired, the drain pipe 37 for the cock can be led directly to the sewer trap as shown in Fig. 4.

With this -arrangement the supply pipe 22 is drained at its lowest point, no water being left standing therein, and as the water passes through the drain cock in the manner described, it will, of course, create a .vacuum through the entire length of the supply pipe 22 and draw in fresh air, thus aerating the pipe at each operation of filling and draining, which tends to create and preserve a highly sanitary condition of the supply pipe.

The link 26 is adjustably connected at its upper end with the' pedal lever 38, which pedal lever is hung from depending lugs 39 on the underside ofthe base plate, the lever, for compactness, being preferably arranged as shown, surrounding the waste pipe 16 with its opposite end curved upwardly and passing through an aperture 40 in the base plate,

a foot pe al 41 being pinned or secured in any suitab e manner to the upwardly curved end of the lever 38. Preferably the baseplate will be provided with depending guiding lugs 42 to control and guide the movements of the lever 38 and prevent any side movements thereto. The pedal 41 projects outwardly through a narrow slot 43 in the Wall of the pedestal at thebase 44 of the pedestal, into the pedestal crescent so that it may be readily manipulated by the foot. With this arrangement it will be seen that when the pedal 41A is depressed, the lever 38 vmeans (not shown).

'mit the supply valve to close and open the waste for draining.

The upper section of the waste pipe 16 is provided with a cap nut 45, which is recessed at its upper end to form a gasketreceiving groove in which a suitable gasket 46 is placed, and provides a slip joint union with the bowl waste 47, the lower end of which bowl waste is tapered so that it may be slipped into -the cap nut and past the gasket readily, and when brought to position will form a water and gas tight slip joint. The bowl-waste 47 is secured to the bowl by the screws 48,1which pass through the bowl 49 and engage the head of the bowl waste 47, a packing 50 being interposed between the headA of the bowl waste and the bottom of the bowl as shown in Fig. 2. Said screws 48 serve also to fasten the strainer 51 in place, which strainer comprises any suitable grated portion and a central sleeve 52 rising to a considerable distance above the bottom of the bowl and surrounding the supply pipe.

becured to the underside of the bowl waste head is a packing, which, as shown, com prises a gasket 53 of any suitable material and which is held by the annular ring 54 and suitable holding screws, this packing engaging the upperlend of a sleeve 55 which surrounds the waste pipe, as best shown in Fig. 2, said sleeve at its lower end being threaded into a boss 56 on the base-plate 10 so as to be firmly anchored thereto. When the bowl 49 with its attached waste pipe and the packing just described is dropped into place, the packing 53 will effectually seal the upper end of the pipe and a dead air chamber is thus formed by the pipe 55, surrounding the waste pipe audits contained supply pipe, and surrounding this dead air chamber will be the pedestal 15 with its relatively large and practically closed air chamber.

The bowl 49 not only rests upon and seals effectually the pipe 55, but it rests also on the upper part of the pedestal 15 as shown and may be secured there/to by any suitable In order to lock the pedestal and its associated parts in place, it is preferably, after being located on the pins 13 in the base-plate, secured by means of a clamping pla-te 57 surrounding the pipe 55 and bearing against lugs 58 on the inner wall of the pedestal. The said clamping plate 57 is forced downwardly to clamp the pedestal firmly in position by means of screws 59 passing through a plate 60, which plate bears againstpins or lugs 61 projecting outwardly from the pipe 55. l'For convenienc'e in assembling,ithe plate 60, which is apertured to slip over the pipe 55, is provided with radial slots 62, which will pass over the ins 61, and the plate 60 canthen be rotate so as to carry the slots out of line and give a bearing for the plate against lthe pins when the screws are set up. From the foregoing it will be seen that, upon adjusting the plates within the pedestal and about the dead air chamber pipe and then setting up the screws 59 the pedestal and the parts carried thereby will be firmly clamped, and furthermore, that the arrangenmet is such that by simply removing the bowl 49 the parts are readily accessible for dismantling and taking down the fountain.

The supply pipe 22 extends 'upwardly into the bowl waste and is there coupled with the bubbler head pipe 63 which in turn carries any suitable bubbling head 64.

From the foregoing itis clear that a drinking fountain is provided in which the supply and waste are so disposed that danger of freezing isvreliminated; in which the supply is protected from contamination; which may be readily assembled and taken down for inspection and repair; and lin which automatic flow and drainoccurs on manipulation of the supply-valve operating devices.

In the construction shown in Figures 8 and 9, we have illustrated a slightly dili'erent form of pedal lever and valve operating mechanism.

Instead of the lever arrangement shown in Figures 1 and 2, we provide the bell v without departing from the lspirit of the incrank lever having the foot pedal 66, said lever 65 being mounted in standards or supports 67 b-y means of the pivot pin 68. The upper end of the lever 65 is pivotally connected with a valve operating rod 69 which depends through the opening in the curbing and is connected pivotally with the coupling head 36 of the Ysupply valve 21 and preferably, the said supply valve 21 will be arranged on the side -of the cham.- ber 19 vopposite from that'shown in Figures 1, 3 and 4 in order that the coupling rod 69 may descend directly to the valve and be connected with the head 36.

By this arrangement, we are enabled to dispense with the weighted connecting link with 'which the otherform of the inven-l tion is provided, the normal weight of the connectmg rod: 69 being suicient .to overcome the weight of the pedal lever 65 and maintain the parts in the normal full line position shown, with the pedal lever raised and the supply valve closed.
