ATTORNEYS Patented Aug. 18, 1942 WASH FOUNTAIN Herman E. Heine and William A. Winters, Milwaukee, Wis., assignors to Bradley Washfountain 00., Milwaukee, Wis., a corporation of Wisconsin Application June 10, 1940, Serial No. 339,784

10 Claims.

The invention relates to washfountains and more particularly to an arrangement for the conduction of drainage water .from and the supply of fresh water to a fountain having an elevated centrally disposed spray head.

Heretofore it has been customary to use parts of the vent or drain fittings as the walls for parts of the fresh water supply with the result that if these walls crack or break down, the fresh water supply will become contaminated by contact with waste gases or drain water. One object of the present invention is to provide an arrangement in which the fresh water supply is separated from both the drain passage and the vent by an entirely separate passage and air space or spaces between said supply and drain and vent passages.

A further object of the invention is to provide a wash fountain with a trap having a centralized vent passage with the fresh water supply also centrally disposed and radially spaced from said vent passage.

A further object of the invention is to provide a wash fountain having vent, drain, and fresh water supply passages which particularly are well adapted for sectionalized control through individual foot controlled valves.

Heretofore in fountains of this type the drain passages have usually been formed as vertically extending passages in the spray head supporting tube, and this restricts the areaway in the tube for other pipes and has been overcome in the present invention by providing the drain passages outside the area of the head supporting tube and in the bottom of the basin or in a member clamped directly thereto.

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

Referring to Fig. 1, the numeral ll designates a basin which may be of circular, semi-circular, or other suitable form of metal, stone, or composition material mounted on a support or pedestal l2 of metal, stone, or ceramic material.

The basin H is here shown as formed of sheet metal provided in its bottom with a centrally located drain opening [3 which communicates with a drain fitting M clamped against the bottom side of said basin at said opening by means of bolts I5, there being a rubber packing I6 interposed between said basin and fitting.

The fitting i4 is formed to provide an annular drain passage I1 with an upstanding central cylindrical wall portion l8 which projects upwardly into the basin, and it also has a trap l9 formed integral therewith or connected thereto and to the waste pipe 20 and to a vent pipe 2|, the pipes 20 and 2| being disposed on the same centrally disposed relative to the wall l8 and the opening l3 surrounding said wall.

The wall I8 is threaded at its upper end to take the lower threaded end of a tubular standard 22 which supports a spray head 23 of any suitable construction. As herein shown and also in Fig. 10, the spray head 23 is formed to provide a plurality of separate compartments 24, each of which has its own tempered water supply pipe 25 and a series of outwardly and downwardly directed spray passages 26. The spray head 23 has a hollow central portion 21 through which the vent pipe 2| passes. Each pipe 25 connects with an individually operated cut oif valve 28,

a common fitting or manifold 29 which connects with a shut off valve 30 that in turn connects with a mixing valve 3! of suitable construction having a cold water supply pipe 32 and a hot water supply pipe 33 connected thereto, said mixing valve having an exteriorly disposed operating handle 34, the valve itself, and the valves 30 and 28 being all located in the space within the pedestal.

Each of the valves 28 is mounted on a bracket 35 connected to a bracket part 36 secured to the wall of the pedestal, and at its lower end the bracket has a base member portion 31 formed integral therewith or connected thereto and also has spaced ears 38 carrying a pivot pin 39 for a foot operated treadle lever 49 which extends through a slot 4| in the pedestal and is connected exterior of the pedestal to a sectionalized foot rail 42, and at its inner end 43 has a head engaging the lower end of a tappet member 44 which is normally moved to retracted position by a spring 45 and whose upper end 44' is adapted to engage the lower end of a poppet valve of any suitable construction, not shown in detail but shown in the application of Howard A. Mullett, Serial No. 235,735, filed October 19, 1938. The valve 39 is always open unless it is necessary to shut off the tempered water supply because of repairs to any of the valves 28.

With this construction downward pressure on the rail 42 causes the lever 49 operated by this section of the rail to move the tappet 44 upwardly to open the valve '28 and allow tempered water to fiow into that section 24 of the spray head controlled by said valve which thereupon delivers a series of fine jets of water from the spray openings 26 into the basin, the waste water flowing to the opening l3 and thence through the drain l1, trap l9 to the wastewater pipe 28. The pedestal has one or more inspection openings 46 covered by removable covers 47.

In some instances it may bedesirable to provide an overhead fresh water supply, and in such a case we have provided the structure shown in Fig. 2 in which the bowl I I provided with the drain opening |3,'the drain and trap fitting l4, the tubular support 22, the sectional spray head 23, and the vent pipe 2| are the same as the first described construction and similarly designated.

A supply of tempered water from the hot and cold inlets associated with a mixing valve 48 is conducted to an annular conduit 49 surrounding the vent pipe 2| and spaced therefrom by an air space 59, said conduit including the spaced pipes and 52 connected at their upper ends to a cap structure 53 and at their lower ends to a cap fitting 54 from which a pipe 55 leads to the valve 30 (shown in Fig. l) and thence to the manifold 29 and individual valves 28, if such are used,

7 from which the tempered fresh water is conducted by the pipes 25 which extend up through the space between the conduit 49 and the support 22 and wall l8 of the drain and lead to the different sections of the spray head 23 as in the first described construction, it being noted that both the conduit 49 and the pipes 25 are separated both from the drain'passage and the vent pipe by an air space so as to prevent contamination of the fresh water supply.- Also in the structures shown in Figs. 1 and 2 the vent pipe 2| is not itself a water wall forming member.

In Figs. 3 to '7, inclusive, we show-two different forms of drain connections that may be used in place of the drain member I4 and its mounting on the bottom of the basin.

In Figs. 3 to 5 we show the basin provided with a central opening 56 and a series of drain holes-51 radially spaced from said openings. A threaded spud 58 projects through the opening 56 and is used as a clamping nut to engage the internally threaded upper end 59 of a drain and trap fitting 68 which is provided with an annular upper inlet 6| that registers with the holes 51 when said fitting is screwed up into sealing engagement'with the bottom of the basin II and more particularly against a rubber sealing strip 62 interposed between said basin and fitting. The fitting 69 has a threaded opening 63 aligned with the opening 59 thereof so as to facilitate engagement with the spud, and a separator pipe 64 is mounted at its lower end in said opening and extends up to a point above the level of the top of the basin. The spray head supporting standard 65 is mounted at its lower end in the recessed upper end 66 of the spud 58. The upper threaded end 59 forms a ring which is connected to the body of the fitting by bridge pieces 61, Fig. 5 showing a plan view of this fitting which may have a trap such as a trap l9 formed integral therewith or connected thereto.

In Figs. 6 and 7 we show the basin II as provided with a central opening 68 with a downturned or curved edge which is clamped between a spud 69 and a drain and trap fitting 10. The spud 69 is shown in plan in Fig. 7 and is provided with an upstanding internally threaded cylindrical portion II, a series of radially disposed drain openings 12 and a depending externally threaded cylindrical portion 13 which engages the upper threaded opening 14 of the fitting 18, said fitting also having a threaded opening 15 aligned with the opening 14 so as to facilitate engagement with the spud and a separator pipe 16 is mounted at its lower end in said opening and extends up to a point above the level of the top of the basin. The spray head supporting standard H is mounted at its lower end in the threaded part H of the spud 69.

In Fig. 8 we show a drain fitting for a stone or terrazzo composition basin having a central opening I8 with a recessed top in which a spud 19 is mounted and provided with an externally threaded lower end 89 which engages the internally threaded opening 8| of a drain and trap fitting 82 which is identical to the fitting 10 shown in Fig. 6. The spud 18 is provided with a series of radially spaced holes 83 similar to the holes 12 of the spud 89 and with an annular seat 84 for a spray head supporting tube 85. A threaded opening 86 in the fitting 82 is similar to the opening 15 and has the separator pipe 81, similar to the pipe 16, in threaded engagement therewith. a

In Fig. 9 we show a drain fitting for cast stone basin II" in which a centrally located metal drain conduit 88 is inset in the basin during the casting process and is provided with a series of openings 99, similar to the openings 12, and has a central opening 98 in which a spud 9| is mounted. A drain and trap fitting 92 identical with the drain member 69 previously described is clamped in sealing engagement with the bottom of the conduit 88 by a threaded connection with the lower threaded end 93 of the spud 9| which, as in the form shown in Fig. 3, has the spray head supporting tube 94 mounted in the upper recessed end thereof. The threaded opening 95 in the fitting 92 is similar to the opening 63 and has the lower end of the separator pipe 96 in threaded engagement therewith.

With all the different forms of drain fittings herein shown the arrangements for the vent pipe 2| and the fresh water supply pipes shown in Figs. 1 and 2 may be employed.

It is also to be understood that where sectional spray heads are not used that but a single fresh or tempered water supply pipe extending up from below directly to the spray head as in the form shown in Fig. 1 but without the valve 28 and its operating mechanism or an overhead supply similar to the form shown in Fig. 2 but with a direct connection with the spray head through the direct connection of said head with a conduit suchas the conduit 49 may be used.

We 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.
