12 Claims.

The invention relates to sprayheads for washfountains.

In some sections of the country the water contains considerable solids or semi-solids that in time clog the spray orifices of the sprayhead and thus interfere with its efficient operation. Furthermore, these solids collect in the chamber behind the sprayhead and thus change the rate of delivery of the water through the nozzles from that originally intended. In order to obviate these difficulties it is the object of this invention to provide a two piece sprayhead in which the nozzle passages and the chamber behind said passages may be readily cleaned of sediment or foreign particles.

It is a further object of the invention to provide a sprayhead in which the valve for the spraying fluid opens into the chamber provided with the spray orifices, and an impact member is interposed between the valve port and said orifices to prevent water spurting out beyond the confines of the basin into which the sprayhead discharges when the sprayhead parts are in a cleaning position.

A further object of the invention is to provide a sprayhea-d in which the inlet valve has a removable seat member which forms a hold-down means for the spray fixture.

A further object of the invention is to provide a multi-part sprayhead in which one of the parts thereof is limited in its movement to a cleaning position by a stop on the supporting standard for said sprayhead.

The invention further consists in the several features hereinafter set forth and more particuin cleaning position;

Fig. 6 is a detail side elevation view of one of the parts shown in Fig. 4;

. Fig. '7 is a detail sectional view of one of the parts shown in Fig. 1 showing certain. modifications;

Fig. 8 is a detail side elevation view of the part shown in Fig. 7

Fig. 9 is a detail sectional View of another of the parts shown in Fig. 1 showing certain modifications.

Referring to Figs. 1 to 3 inclusive of the drawings, the sprayhead includes two main metal members it] and H.

The member I0 is of circular shape formed to provide a base portion l2 and a top portion l3 spaced from said base portion by the integral ribs or spaced columns [4 to form a chamber ID.

The base portion 12 has a centrally disposed threaded opening it therein, an annular upstanding impact portion I6 concentric with said opening and a flat surface I! extending from said portion 35 to the outer cylindrical edge l8. The portion l2 has a depending annular flange I9 having a threaded outer side which is spaced inwardly from the edge l8.

The top portion I3 is of circular formation with a centrally disposed valve stem mounting boss 2| and a comically inclined outer edge portion 22 having a lower nozzle forming surface 23.

The member II is a flanged ring having a threaded base flange 24, a base web 25, an upstanding fiange 26, and an. outer drip flange 24'. The upper edge of the flange 26 is provided with a plurality of nozzle forming notches 21 which have the same inclination as the surface 23 and cooperate therewith when the parts are in assembled position to provide a plurality of downwardly inclined closely associated spray orifices 28. The threaded connection between the side 20 of the member Ill and the base flange 24 permits the parts to be assembled and held in spray forming position, and when so assembled, a yieidable washer 29 may be interposed between the base portions of these parts. For turning the member H relative to the member I0 one or more holes 30 may be provided in fillets in said member I l for receiving a spanner wrench or other suitable tool.

A pipe fitting BI is formed at its upper end 32 to provide a renewable valve seat and is threaded at 33 to removably engage the threaded opening 15 of the part It), a washer 34 being interposed between said part 10 and a shoulder 35 on said fitting. This fitting has an enlarged bore 36 at its lower end threaded to receive the washing fluid supply pipe 31. This fitting 3| when screwed into the part I0 acts as a hold-down means for bringing the member l0 against the upper end of the standard 41.

A flat face rubber or suitable composition valve 38 cooperates with the seat 32 and is removably secured to its stem 39 by a screw 49, said stem having a threaded portion 4! engaging the threaded bore 42 of the boss 2|, the upper end 43 of said stem working through a stufiing box 44 of known construction, the exposed end of said stem carrying an operating handle 45. Part of the stem is shown enclosed by a tubular member 46 which is used to carry a soap tray (not shown).

The head engages a hollow tubular standard 41 whose upper end seats in an annular groove 48 in the part ill, and at some point below this end it is provided with an annular stop shoulder 49 to limit the movement of the member I I when it is moved to a cleaning position to prevent the ring falling upon the enameled or other finished surface of the bowl beneath it and also possible deformation of said ring.

With this construction, the turning of the stem 39 in the proper direction raises the valve 38 from its seat 32 and allows water to pass into the chamber 16 and thence through the orifices 28 in a downwardly inclined direction and in an annularly spaced series of small streams of low velocity since the volume of the chamber Ill acts to reduce the pressure from that in the supply pipe 37. If the orifices 28 should tend to clog, then the ring member H may be turned down to separate the parts of the sprayhead, as shown in Fig. 2, so that the orifices may be readily cleaned. If sediment should collect in the chamber I B which would tend to reduce its volume and thus increase the pressure of the water through the orifices beyond a predetermined desired value. then the turning down of the ring member I l to the position shown in Fig. 2 where the edge 21 of said ring member is below the flat surface I! of the part II] permits the water flushing out the sediment in the sprayhead chamber IE3. During this flushing operation the impact member 16 prevents the water from the valve controlled opening from spurting out through the opening 5E] provided by the parts of the sprayhead in their cleaning position beyond the confines of the basin into which the sprayhead discharges, but it does not prevent an efficient flushing of the chamber l. With the parts in assembled formation the drip flange 24' prevents any drip from the nozzles working down along the standard 41 as this drip will fall ofi the lower edge of said flange.

In some types of washfountains a vent pipe passes centrally through the spray fixture, and in Fig. 4 I have shown my improved sprayhead applied to an arrangement of this kind wherein is the centrally disposed vent pipe, 52 and 53 concentrically disposed pipes forming a water inlet passage 54, the pipe 52 being spaced from the pipe 5!. The sprayhead member 55 is similar to the member ill and is formed to provide a base portion I2 and a top portion [3 spaced from said base portion by the integral ribs or spaced columns I4 to form the chamber ill".

The base portion 12 has a centrally disposed threaded flange portion [5, a flushing surface portion ll" extending to the outer cylindrical edge l8, and a depending annular flange l9 threaded to receive the upper threaded end of the standard 4! and also provides a depending flange having a threaded outer side 29 which is spaced inwardly from the edge IS.

The top portion I3 is of circular formation with a centrally disposed threaded bore 2| for the pipe 53 and a conically inclined outer edge portion 22 having a lower nozzle forming plain surface 23' similar to the surface 23.

The member H is substantially identical with the member H and is a flanged ring having the threaded base flange 56, a base web 25, an upstanding flange 26' and an outer drip flange 51, the flange 25 being provided with nozzle notches 21' similar to the notches 21' and which cooperate with the surface 23' to form a. plurality of downwardly inclined closely associated spray orifices 28'. The threaded connection between the flange portion 1 6' and the base flange 56 permits the parts to be assembled and held in spray forming position, and when so assembled, a yield able washer 29' may be interposed between the base portions of these parts.

The water passing through the passage 54 is controlled in any suitable manner usually through a mixing valve (not shown). If the orifices 28 should tend to clog, then the ring member ll may be turned down as in the first construction to separate the parts of the sprayhead so that ready access may be had to the parts forming the orifices. If objectionable sediment should collect in the chamber I 0", then the turning down of the member I I to bring its edge 21 below the flat surface l1 permits the water flushing out the sediment in said chamber.

Certain advantages of the invention may be obtained where the spray orifices are formed wholly in either one or the other of the parts in and H. In Fig. '7 the part 58 is similar to the part II! previously described except that downwardly inclined spray orifices 59 are drilled in the lower edge portion of the part 22", similar to the part 22, and the part 50, similar to the part II, has a smooth edge similar to the edge 23 engaging the smooth edge Bl of said part 58. In Fig. 9 the part 62 is similar to the part I I previously described except that downwardly in part 65 is generally similar to the part II) except that the bottom portion 66 with its depending flange 61 does not have a part extending therefrom and instead of a smooth edge for the nozzle forming portion, the nozzle forming notches 68, similar to the notches 21, are formed in this edge. A threaded ring member 69 has a threaded flange to engage the threads of the flange B1 and a flat upper surface H which when screwed down to a cleaning position, forms an extension of the flat flushing surface portion 12 of the part 65 as shown in Fig. 5. In this form the outer edge 13 of the member 69 is a conically inclined fiat surface which cooperates with the notches 58 when the parts are in assembled position to form downwardly inclined closely associated spray orifices similar to 28. The part 69 has a peripheral depending flange 14 to prevent drip running down the sides of the standard 41. scribed construction has the same advantages as that of the first described construction as regards the cleaning of the spray orifices and the flushing of the pressure reducing chamber 14.

The sprayhead above described is used in connection with washfountains of the general type shown in U. S. Patent No. 1,477,189, of December 11, 1923, to Louis Schlesinger wherein the small This last destreams of low velocity water are directed downwardly toward the outer side of the cylindrical basin.
