Mullett, Milwaukee, Wis., assignor to Bradley Washfountain Company, Milwaukee, Wis., a corporation of Wisconsin Application July 9, 1937, SerialNo. 152,688

4 Claims.

The invention relates to sprayheads for washfountains.

One object of the invention is to provide a sprayhead in which the spraying portion is formed of separable members and in which the parts are so constructed and arranged that a single ring-shaped nOZZle member may be used to provide a spray area formed of one or more segmental zones, and in this connection the present invention provides certain modifications in sprayhead over that of my copending application Serial No. 105,896, filed October 16, 1936.

A further object of the invention is to provide a sprayhead whose body portion is so constructed that it may be connected to its supply fitting by the engagement of a suitable turning tool with ribs on the interior of said body portion. 7

A further object of the invention is to provide a sprayheadin which the body portion is formed to provide a recessed portion, the walls of which deflect the incoming water from issuing in a straight path through the spray orifices so as to prevent water spurting out beyond the confines of the basin when the parts forming spray orifices are disconnected.

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

In the drawings;

Fig. 1 is a vertical sectional view through a sprayhead embodying the invention;

Fig. 2 is a detail plan view of a portion of the sprayhead, parts being broken away and parts being shown in section; v

Fig. 3 is a plan view of one of the sprayhead parts;

Fig. 4 is a sectional view through another form of sprayhead embodying the invention;

Fig. 5 is a detail plan view of the device shown in Fig. 4 with parts broken away at different depths to show the interior construction;

Fig. 6 is a detail view of one of the parts of the sprayhead.

Referring to Figs. 1 to 3 inclusive of the drawings, the sprayhead includes three main metal members I, 8, and 9.

The member I is of circular shape formed to provide a cup-shaped base portion I0 and a top portion II spaced from said base portion by the integral ribs or spaced columns I2, said base portion having an annular flange I3 adjacent the recessed part I4 Whose exterior wall is threaded at I5. The bottom of the cup has a centrally disposed threaded opening I6 therein.

1 The top portion H is of circular formation with.

a centrally disposed valve stem mounting boss I'I andv a conically inclined outer edge portion I8 having a lower flat nozzle forming surface I9.

The member 8 is a ring having a thickened conical top edge 20 which through a portion of its periphery is provided with a plurality of nozzle forming notches 22 which have the same inclination as the surface I9 and cooperate therewith when the parts are in assembled position to provide a plurality of downwardly inclined. closely associated spray orifices 23. This member 20 is centered by the peripheral edge of the flange I3 and is held in assembled relation with the member l by the member 9 in the form of an annular clamping ring having a threaded portion 24 engaging the thread I5 and a flat top portion 25 engageable with the bottom side of the ring 8. This ring is provided with openings 26 in fillets thereof for the engagement of a suitable spanner wrench.

A pipe fitting 21 is formed at its upper end 28 to provide a renewable valve seat and is threaded at 29 to removably engage the threaded opening I6 of the part I, a washer 30 being interposed between said part 'I and a shoulder 3I on said fitting. This fitting has an enlarged bore 32 at its lower end threaded to receive the washing fluid supply pipe 33. This fitting 21- When screwed into the base portion I0 acts as a hold-down means for bringing the member I against the upper end of the standard 34.

A flat face rubber or suitable composition valve 35 cooperates with the seat 28 and is removablyv secured to its stem 36 by a screw 31, said stem having a threaded portion 38 engaging the threaded bore 39 of the boss H, the upper end E0 of said stem working through a stufiing box M of known construction, the exposed end of said stem carrying an operating handle 42. Part of the stem is shown enclosed by a tubular member '43 which is used to carry a soap tray 44. An

ring 9 falling upon the enameled or other finished surface of the bowl beneath it.

With this construction, the turning of the stem 36 in the proper direction raises the valve 35 from its seat 28 and. allows water to pass into the interior of the body 1 and thence through the orifices 23 in a downwardly inclined direction at a greater or less velocity depending upon the amount of opening of the valve 35 and in an annularly spaced series of small streams of relatively low velocity since the chamber in the body acts to reduce the pressure from that in the supply pipe 33. If the orifices 23 should tend to clog, then the clamping ring 9 may be loosened so that the ring 8 may be dropped down to an open position in which ready access is had to the parts forming the orifice and to the interior of the body. It is also to be noted that by forming the part 2i] as a separable ring, the notches 22 may be provided on only a part of the periphery thereof and be positioned in any angular position desired relative to the body 1 and clamped in this position by the ring 9 so that the. device may be used on semi-circular or sectional head washfountains. Furthermore, the side walls of the recessed portion I4 act to. deflect the water, issuing from the inlet fitting. 21, from a. straight path through the orifices 23 so. as to prevent. water. spurting out beyond the. confines of the basin.

In some forms of washfountains in order to conserve the supply of water the sprayhead. is. formed of a plurality .of outlet compartments, each controlled by its own valve, and Figs. 4, 5,

and 6 show the invention applied to this form.

of fountain. I

In these figures the numeral 41 designates the main body portion, 48 the nozzle ring member,- and 49' the clamping. ring.

The-body portion 41 has a centrally disposed inlet chamber 59, and a plurality of annularly disposed outer chambers separated from each other by the radial partitions 52 and. having valve controlled inlet fittings 53' connecting themwith the chamber 55 which is supplied with waterfrom a, central sup-ply pipe- 54-, i

Each control valve 55 has-a head 55 engageable with a seat on the fitting 53 to close 011- the outer from .the inner chambenand its stem isthreaded to engage the threaded bore 51'- of the plug'fitti-ng 58'which has a detachable screw thread connection 59 with said body. The stem of the valve extends through a stuffing box 60 and carries an operating handle 6!.

'The body portion 4-1 has an annular recess formed in its bottomhaving a vertically disposed cylindrical wall 62- and a downwardly inclined wall 63.

The nozzle ring me 'iber 48 isformed with'top and inner side walls to engage the walls 62 and 53 and is also formedto provide recessed segmental sections 64 with partition portions 65- between the sections-.- The top' portions of the sections 54 are provided-with a plurality of nozzle forming notches 65- which have the same inclination asthe wall 63 and cooperate therewith when the parts are in assembled position to" provide a plurality of downwardly inclined closely associated spray orifices 61 for each of the outer chamber portions of the head.

The nozzle ringmember 48 is held in -assem bled relation with thebody 41 by the clamping ring 49 which has a threaded portion 68' engaging the threaded lower end 59 of said body and a fiat. top portion :engageable withthebottom side of the ring member 48.

The top of the body t? has a centrally disposed threaded opening H closed by a pipe plug 12 except when the inlet pipe 54 is connected there'- to in case the supplycomes in from above the sprayhead. The exterior sides of the opening H are threaded to receive a tubular member 13 which is used to carry a soap tray 14. The head is mounted on a standard in a manner similar to the mounting of the first described sprayhead on the standard 46.

With this construction, the opening of any one of the valves allows water to enter the outer chamber 5| controlled thereby and thence pass through the spray openings 61 provided for that chamber and directing the water in a series of downwardly inclined low velocity streams into the wash basin, not shown. It is to be noted that the partition portion 65 of the ring 48 is 1 adapted to cooperate with the partitions 52 to separate the outer chambers from each other.

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