To all whom t may concern:

Be it known that l, Lno SIMMONS, a citizen of the United States of America, and a resident of Vashington, District of Columbia, have invented certain new and useful lmprovements in and Relating to Spray Heads for Shower Baths, of which the following' is a specification.

This invention relates to certain improvements in spray heads for shower baths and other purposes; and the objects and nature ofthe invention will be readily understood by those skilled in the art in the light of the Vfollowing explanation of the accompanying drawings that illustrate what l now believe to be the preferred mechanical expression or embodiment of my invention from among other forms, constructions and arrangements within the spirit and scope thereof.

An object of the invention is to provide an exceedingly simple and effective device for producing a water shower for shower bath purposes that will overcome certain disadvantages incidental Vto the" use of the perforated face plate or so-called rose heads,

now generally employed for spray head shower baths, and that will utilize means to form a water curtain and then break up such curtain to form streams or attain the desired spray all without the use of a closed hollow head having its outlet side closed by a perforated face plate or wall.

With this and other objects inrview my invention consists in certain novel features in construction and in formations and arrangements of features, as more fully and particularly hereinafter explained and specified.

Referring to the accompanying drawings, forming part hereof:

Fig. l is a vertical section of a shower bath spray device embodying my invention.

Fig. 2 is a section on line 2 2 of Fig. 1.

- My invention embodies a cavity of preferably substantial depth or length, closed except at its large open outlet end, and providing an unbroken annular approximately conoidal wall curving inwardly and longitudinally of the "cavity from an annular orv circular water curtain breaking-up rim surroui'idingthe open end of the cavity, to the depressed centerV of the closed end of thecavity constituting the approximate apex of the wall. The interior surface of this cavity, exclusive of said rim, is preferably smooth and formed to cause th'e water from ln the particular example illustrated by the accompanying drawings, l show an embodiment of my invention formed and arranged to spray the water downwardly and constitute an overhead spray head, that ein-- bodies a depending hollow head or belll of approximate conoidal shape and open at its comparatively large end. l

The lower circular or annular edge ,por-

tion of this hollow head that surrounds the large bottom opening, is formed4 at its an-v nula'r inner surface to provide a toothed or irregular water separating or breaking up annular rim 2, as more fully described hereinafter.

The preferably smooth unbroken annular interior surface 3 of the head curves and contracts or converges upwardly longitudinally of the head, from the rim 2 to the apex or center t which is alined with the longitudinal axis and center of the open bottom of the head and located at the extreme inner end or top of the interior of the head.

The water, under1 head orv pressure, is introduced from a point withinA the head in the form of a centrally arranged upwardly directed single stream or j et directed against the closed center or apexd in the line of the longitudinal axis of the head. The interior surfaces 3, 4, are intended and designed to cause the jet of water to spread evenly over and cover the surface 3 and descend along said surface in the form of an unbroken annular stream or curtain until the rim 2 is encountered. This rim 2 is designed to separate this (what is then a hollow cylindrical) curtain intol an annular series of parallel separate streams that will fall from the lower edge of the head to perform shower bath functions.

The interior surfaces 3, t, are so designed -as to reduce to the minimum, possiblity of the water jet being so sprayed or otherwise broken up by engagement with the center 4f as to drop vertically from the upper end of the head through the openbottom of the head. On the contrary, the interior surface formation of the head is designed to cause the water to spread approximately uniformly radially from the apex el as a center and closely followY the surface 3 downwardly in a smooth stream completely covering said surface without substantial dripping or dropping therefrom until thel rim 2 is reached.

In the example illustrated, the water is discharged under pressure upwardly centrally against the apex l,'in the forni of a jet, from a vertical nozzle centrally arranged within the head andspaced a Vshort distance from saidapex. rIhis nozzle 5, can becarried by an angle supply pipe 6, lo cated within the head and carried thereby and extending radially from and secured to the shell or wall thereof.

The pipe 6 can be connected with and supplied from the water supply system of the building, through the medium of water supply pipe 7. screwed into a tapped water supply duct 8 extending radiallythrough the shell or wall of the head to supply pipe Vo.

The spray head l can be mounted or supported so as to depend at the desired distance above the floor, inany suitable manner or by any suitable means. For instance, I show the head formed with a cent-ral exterior top boss 9, having a tapped socket 10, receiving post 1l depending from base 12 secured to the ceiling or other overhead support.

.In the particular embodimentJ illustrated as an example. the bottom or outlet end of the head is entirely open and unobstructed except for the internal rim 2, although I do not Vwish to so limit all features of my invention.

.also, in this example, the lower end of the head is internally slightly contracted in diameter to more or less confine and prevent undue spreadingV of the water shower descending therefrom, and also the water breaking up rim embodies an annular series of v similar uniformly spaced radial projections Qa' forming an annular serieswithin the head and radially intersecting the path of the descending annular water curtain, to provide an annular series of intervening uniformly spaced notches forming vertical Y water passages 2h.

The function of the projections 2a is to sub-divide the annular water current into separate streams that pass down through theV water passages 2". Y

This water curtain breaking-up rim 2, can be variously formed to provide the annular series Iof water passages, whether or not provided for'bythe particular radial internal projections 2a, which in this inst-ance are in the form of radially wedge-shaped. beveled 'or tapered teeththat arev vertically wedgeshapeat their top ends or upwardly beveled to divide the descending water and concentrate the same in the vertical water passages.

It is evident that various changes, modiclosed at the oppositeend to constitute an elongated approximately conoidal water` cifirtain-forming wall and provided with an internal circular water curtain breaking-up rim around its open end, and means arranged to discharge a water jet within the head and centrally against the closed end thereof.

2. A water spraying device comprising'a hollow headclosed at one endand open at the opposite end for discharge of water in streams for shower bath purposes, and means for discharging a jet of water under pressure, centrally and longitudinally within the head and against the interior surface of the closedend thereof, the interior surface of said head being formed to cause the water from said jet to spread over'said surface and travel toward said discharge end, said head beingformed at said discharge end to divide the water into such streams.

3. A hollow head closed Tat one end and formed at the opposite end for water discharge in an annular series of sprays in combination with a nozzle arranged to discharge a water jet longitudinally'.withinfthe head and centrally against the inner surface of the closed end thereof.

4. A hollow head closed at one end and open at its opposite water discharge end, the annular internal surface of the head being approximately conoidal from the center of said closed end toward thedischarge end, a nozzle arranged to direct a jet of water under pressure centrally against said closed end, means being provided to cause the water to discharge from the head in `spraying streams. i i I 5. A hollow head having a closed end and van opposite discharge end provided with water'curtain breaking-up means, the annular interior surface of the head curving and flaring from said'closed end towardsaid discharge end for outward longitudinal flow of an annular curtain of watenand means for discharging a central 'longitudinall Astream of water within theih'ead'and against the inner surface of the closed end thereof.

6. A hollow head closedV atonev end and at the Vopposite end provided with a surrounding rim of longitudinal separate water discharge passages, the annular inner surface of the head being ismooth `for How of water, and a water pipe carried by the head and adapted to be connected with a building water supply and provided with a water discharge arranged to direct a jet of water centrally and longitudinally within the head against the interior surface thereof to form an unbroken annular water curtain moving longitudinally along the inner surface of the head to said discharge passages to be thereby broken up and discharged as spray streams.

7. A hollow head closed at its upper end and open at its lower end and exteriorly formed to be attached to and depend from a support, and a water supply pipe having an upwardly directed discharge arranged to discharge a stream of water longitudinally within the head and centrally against the inner surface of the closed end thereof, the lower end of said head provided with an internal circle of radial inwardly projecting teeth forming intervening longitudinal water passages with the curved annular inner surface of the head leading thereto.

8. A shower bath water spraying device presenting an approximately conoidal cavity having a discharge end with a surround ing water curtain breaking-up rim, and means to discharge water into the opposite end of the cavity to form a water curtain moving towardsaid discharge end.

9. A hollow head having an open discharge end formed to provide a water curtain breaking-up rim, and means to discharge water into the opposite end of the head to form a water curtain therein Inoving toward said rim.
