UNITED STATES 'i SHOWER HEAD.

Application med March ze, 1923.` seriai No.` '528310.'

T 0 all whom t may concern:

Be it known that I, SHERMAN WV. MAL- LERY, a citizen of the United States, and a resident of Ridgefield Park, in the county of Bergen and State of New Jersey, have invented a new and Improved Shower Head, of which the following is a full, clear, and exact description.

This invention relates to improvements in bath appliances and has particular reference to a shower head.

An object of the invention is to utilize the pressure of water entering thegshower head to close the drain thereofwhich is au` tomatically opened when said pressure is. discontinued.

Another object is to so ,construct the shower head that access may be readilyy had to the interior thereof for making repairs and the like. n Y.

A further object is to provide an .improved constructionby means of which the interior ofA the head may be quickly and thoroughly cleansed without the necessity of .disassembling the same.

A still further object is to avoidthe usual prolonged dripping of water from the head after the flow has been discontinued by the provision of means which will expedite the `complete emptying of water from the head immediately following the shutting off of the flow thereof. c

The above and other objects will appear more clearly from the following detail description, when taken inconnection with the Y accompanying drawing, `which illustrates preferred embodiments of the inventivessf In the drawing- Figure 1 is a vertical longitudinal section of the shower head constructed in accordance with the invention; v

Figure 2 isa section on the Figure 1;

line 2-2 of Figure 3 is a section on the line 3--3 of Figure 4;

Figure 4 is a section on the line-44 of Figure 1; and V f Figure 5 is a fragmentary View, partly in section, illustrating a slightly different construction of the bottom plate of the head. Referring more particularly to Figures 1 to 4, which illustrate a preferred embodimentfof the invention, the shower head is` shown v-as comprising a body 6 having an inlet opening y7 in the top thereof in which aV presently appear.

. coupling member 8 is mounted and held in position by the nut 9. The innerV end of the coupling 8y projects into the interior of the body and the exterior end ofv saidcoupling is internally screw .threaded to receive one end of the supply pipe 10 through which water enters the head.

The lower edge of the body 6 is provided with an externally threaded flange 11 for receiving the bottom plate 12 which is ofsubstantially .inverted frusto-conical formation and which is provided vin its lowermost and central portion with a drain opening 13 in the `form of a valve seat, which is preferably in alignment withthe supply pipev 10 yand through-'which water andsediment in the Aheadimay be drained, as willv later b e described. The bottom plate 12 is providedat diametrically` opposite points with the hanldles 14 utilized to attach and detach the plate vfrom the body 6 wheneverit is desired to obtain access to the ,interior ofthe body.v Theplate 12 is further providedwith a plurality of circular rows of apertures 15 ar. ranged concentrically with respect tothe drain opening 13 and said apertures are preferably flared outwardly, as indicated in Figure 1, to insure the passage of sediment through the plate after the sediment enters ythe inner ends of said apertures. It has also Vbeen found in Ypracticethat the openings tapered-in this manner cause the waterv to fall .in drops instead of a constant stream.

Carried by the plate 12 and `positioned interiorly of the body indirect alignment with the drain opening 13 isa guide member 16 having vspaced extensionsl'? at-its lower end which receive screwsor other fasteners Y 18 for securing the guide member in position. A valvestemr 19Lis rotatably and slidably mounted inthe guide member 16 v and has itsk lowernend projecting through the drain opening 13and provided with a knurled portion 20 to facilitate the turning of the valve stem, for a purpose which vwill stem l19fadjacent its lowerendis a valve 21 whichlis movable between the lower end of the guide member 16 and the drain. opening v13. `The valve 21 isno'rrnally v.maincoil spring 22, the lower en d of which is seated on a portion of the guidemember 16,

of the valve stem? 19 by .means of a set Formed upon the valve tained lin its open position by means of a plate25 and eXert a pressure thereon which is sufficient to overcome the tension of the spring 22 and thus force the valve stem 19, together with the valve 21 and arm 23 downwardly until the valve 21 is seated in the drain opening 13 thus closingy the same, thereby causing the water in the body 6 to flow through the apertures in the bottom plate 12 while the device is in operation.

Immediately upon the discontinuance of the flow of water through the pipe 10 into the body 6 the spring 22 operates to force the valve vstem 1.9 and valve 21 upwardly to their nor-mal positions thus opening the drain opening13 to permit of theaccumulated .water in the head 6 to readily and quickly flow therefrom. In order to further facilitate the emptying of the body after the supply of water has been shut off the valve stem 19 is provided with alongitudinal passage 26 extending from the lower end thereof to a point. adjacent the upper end where said passage Vcommunicates vwith av lateral port 27.- The provision of this passage and port permits of air entering through the valve stem into thebody 6 after. the level of the water has-receded below the port 27 and this air-entering the body will aid in causing the water tofiow rapidly from the head instead of dripping therefrom, as in the ordinary construction of shower heads.

The invention further contemplates means for cleaning the interior surface of the bottom plate 12 of any accumulation of sediadjacent the drain opening 13 -toutheouter periphery of the interior surface yof said bottom plate so that when the scraper memberl is Arotated in a counter-clockwise direction, as viewed inFigurel 2, the same will effectively removeany accumulation of sediment upon the interiorfaceof the-,bottom plate and direct Asuch sediment toward the drain opening 13.V i

To rotate the scraper member 28 'the same is preferably provided with vertically disposed rods 29 one adjacent each end thereof, the lupper'ends of, said rods being slidable in bearings() dpending'k ,fromthe guide arm l23 v .vihich. extends laterally fromthe upper end of the valve stem 19. By thus slidably connecting the scraper yblade 28 with the valve stem 19, it will be apparent that any vertical or sliding movement of the latter member will be relative to the scraper member 28 so that this member will be unaffected by the opening and closing movements of the valve 21 when the Supply of water to the head is turned of'r1 and on. To rotate the scraper member 28 it is only necessary to grasp the lower knurled end 2O of the valve stem 19 and rotate the same in the proper direction. In the cleaning operation a small quantity of water may be permitted to flow into the head before rotating the scraper member so that the sediment removed from the bottom plate by said member will more readily be conveyed to the drain opening. l

In Figure 5, a slightly different form of the invention is disclosed, in which the use ofthe scraper member 28 and its associated parts are dispensed with, .the sediment collecting in the body 6 being prevented from obstructing the openings in the plate 12 through which the water flows by means of small perforated tubular membersv 31 which are threaded upon the, inner ends of nozzles 32, the latter being in turn threaded into suitable openings formed in the bottom plate 12.

What is claimed is:

1. In a shower head, a body having an inlet, a perforated bottom for said body having a drain opening, .a valveguide carried by said bottom, a valvemovablein said guide and operable to close and open said drain opening, means for normally maintaining said valve in open. position, and means normally projecting into said inlet and actuated by the pressure of fluid entering said body for operating said valve to close said drain opening.

2. In a shower head, a body, a perforated bottom therefor having a drain opening, a rotatable member extending through said bottom, and a` scraper movable with said member when the same is rotated and engageable with the inner surface of.. said bottom to direct sediment thereon toward said drain opening.
