11. Claims. (01. 4-195) g The invention relates to wash fountains and more particularly to an arrangement for the conduction of the drainage water from the fountain and the supply of fresh water thereto.

Heretofore it has been customary to run the inlet water supply pipe directly through the drain passage and form one of the joints for said pipe in said passage which'under certain conditions will permit drainage water finding its way into 10- -thesupply water passing to the sprayhead or other 'point of use.- Also where the drain passage is associated with a trap and the supply water comes through a passage in the trap, defective castings may permit the supply water becoming 15 contaminated with water from the drain. In orderto-overcome the above mentioned difiiculties the present invention has for its object to provide asupply-and drainage arrangement whereby the supply water is separated from the drain gol water through an entirely separate passage'and through an air space between the supply and drainage passages. 1

The invention further consists in the several features hereinafter set forth and more particular1y defined by claims at the conclusion hereof.

In the drawings: Fig-,1 is a vertical sectional view of a wash fountain provided with apparatus embodying the invention; 1 m. Fig. 2 is a detailed sectional view taken on the line 22 of Fig. 1;

Fig. 3 is a detailed elevation view of one of the parts of the drain fitting;

Fig. 4 is anenlarged'view'of parts shown in w Fig. Fig. 5 is a detailed sectional view showing another modified form of the invention;

Fig. 6 is a vertical sectional view through a wash fountain provided with another form'of the invention;

Fig. 7 is a sectional view showing certain modifications of the structure shown in Fig. 6;

Fig. 8 is a view similar to Fig. 7 showing another modification. u Referring to Fig. 1, the numeral I0 designates a basin which may be of circular, semi-circular, or other suitable form mounted on a support or pedestal ll.

A'tubular sprayhead supporting member I2 w having drain openings l3 in'its' lower end seats on a spud l4 mounted in a recessed opening IS in the bottom of the basin. The member l2 supports a sprayhead structure l6 which may be similar to" that shown in the prior U. S". Patent designed to project a seriesof streams of water outwardlyand downwardly into the basin.

A drain fitting I! has a'threaded opening IS in its upper end engaging the lower threaded end of the spud I4, a circular chamber l9 formed in said upper end, a passage 20 offset from one side of said chamber and extending downwardly and provided with a threaded lower end 2| en-- gaging a drain pipe 22. The bottom of the chamber i9 is provided with'a threaded'opening 23 10 concentric with the opening l8 and adapted to receive the lower end of a pipe or separator member 24 which extends up'throug h the drain to a height somewhat above the height of the basin' Hi, so that water from the drain will be prevented from overflowing through" said pipe evenlif the basin should become full of waste water.

It will'be noted that passage makes a curve from its point of connection'with the chamber Hi to its lower'end and that a boss is formed on the -wall of said passage inline with the open-v "ing 23' and adjacent a clearance space formed beneath the chamber I9. This boss 25-is provided with a threaded'opening-26 adapted to receive the threaded plug '21? formed on the lower end of an elbow fitting. 28 which is provided. with a side opening into whichthe pipe 29 is threaded and a top openinghintowhich an upwardly extending supply pipe 30 is threaded; The pipe 29 may, besupplied with tempered water through a m; suitable hand controlled mixing valve 3| which hasa hot water connection 32 and a cold water connection 33 leading thereto. The pipe 30 leads directly to the sprayhead l6 and extends through the member. 24 from-ywhich it is spaced by an air gap, said member '24 normally keeping the drain water from coming incontact with the inlet pipe connections including the pipe 39 and fitting. 28, though'if any drainage water should get throughbetween the member 24 and the drain fitting l'l, it will leakout to atmosphere and will not be subjected to any pressures which might tend to force-it intothe supply connections as has occurred where the supply pipe passes directly through the drain passage and has a joint or joints forming part of the wall of the drainpas sage.

In some instancesthe inlet. water supply pipe comes from above the basin and through a valve 5 located; below the basin and then up to the sprayhead, and in such instance the inlet connections may be arranged-as shown in *Fig'. 5 and associated with the .drain fitting [1. As hereinshown in place of theelbow fitting 28,- I. useiarspecialfitting 34,havinga partition;35 and provided with threaded openings 36, 31, 38, and 39. The inlet pipe from an overhead supply extends down to the partition 35 and has threaded connection with the threaded opening 38. The water then passes through the space 4| to the pipe 42 connected with the threaded opening 31 by which it is lead through a valve such as a foot controlledvalve, for example of U. S. Patent No. 2,085,824 of July 6, 1937, and returns by way of pipe 43 connected with the threaded opening 36 to the space 44 from which it passes upwardly to the sprayhead through the pipe 45 connected to the threaded opening 39. It is to be noted that the pipe 45 extends up through the separator pipe 24 similar to the pipe 30 of the first described construction and is separated from pipe 24 by an air gap. The fitting 34 has a threaded boss 46 adapted to engage in the threaded opening 26 in the drain fitting IT.

In those instances where it is desirable to associate a trap directly with the drain, the structure shown in Fig. 6 may be used. As shown the lower threaded end of the spud l5 connects with the threaded end 4'! of a special trap fitting 68 which has the chamber 48' at its upper end connected by an offset passage 49 to the trap or U-shaped portion 50 which connects by a relatively straight passage 5! with an outlet passage 52, the passages 52 and 5! also connected with a vent passage 53 having a threaded outlet 54 which is connected to an upwardly extending vent pipe 55.

The water supply connection leading to the sprayhead, such as E6 of Fig. 1, is formed in this instance between the pipe 55 and a pipe 56 concentric therewith and connected to a manifold 51 whose lower end 58 is sweated to said pipe 55 and has a laterally disposed inlet pipe 59 connected thereto. The supply connection thus formed is completely separated from the drain passage including the member I2 through which it projects by a pipe or separator member 60 which extends up to a height above the top of the basin II] similar to the pipe 24 of the first described construction and at its lower end threads into a nut or threaded plug member 6| which engages the opening 82 inthe wall 63 of the fitting 48 which opening is made large enough to allow the manifold 51 to pass through, so that the vent pipe 55 may be screwed into place.

With this construction the inlet pipe is separated from the drain by the pipe 69 and an air space and has a fluid tight connection with the vent pipe 55.

Where it is not desired to mount the inlet manifold directly on the vent pipe, the modification shown in Fig. 7 may be used wherein the vent pipe 55' is similar to the vent pipe 55 and the supply connection is formed by a manifold 51 and concentric pipes 58' and 56 in threaded engagement therewith, said manifold having the supply pipe 59' connected thereto, the pipes 55', 58', and 56' and the manifold 51' adapted to be substituted for the pipes 55, 56 and manifold 51 shown in Fig. 6, so that the inlet connection including pipes 58' and 56' passes up through the pipe 60. It is to be noted that in this modified form the inlet connection is separate from the drain passage and from the vent associated with the trap in said passage.

In those instances where an upwardly extending vent is provided associated with a trap 48 and the supply comes from above the basin, the details of the inlet connections arranged as shown in Fig. 8 wherein the numeral 55 designates the .vent pipe, and 64 an annular manifold surrounding said vent pipe and having pipes 65, 66, and 61 in threaded engagement therewith, the pipes 85 and 86 cooperating with the manifold 64 to form an annular passage for conducting the inlet water downwardly and having a threaded outlet 68 from which the water may be led through a control valve (not shown) and then conducted to the inlet 69 of an annular passage formed by the pipes 66 and B1 and the manifold. 64 whereby the water is carried to the sprayhead such as the sprayhead I 6 of Fig. 1, it being noted that the outer pipe 6'! is of a diameter to fit within the pipe 60 of Fig. 6 and be spaced therefrom.

I desire it to be understood that this invention is not to be limited to any particular form or arrangement of parts except in so far as such limitations are included in the claims.
