To all whom t may concern.'

Be it known tha'tI, IVILLIAM T. GUTH, a citizen of the United States, and a resident of the city of New York, lfiorough of Brook- Another object of the invention is to pro vide a lavatory with a grooved or inclined surface arranged `in such a manner that ,p water may be directed thereover for producing a cle-an and flushing sheet of water for the entire bowl.

A still further- Object of the invention is to provide a self-cleaning 'lavatory whereby upon the turning of a single spigot, water is discharged in several directions and automatically converted into a sheet as it moves into the bowl proper. i

Referring to the accompanying drawing by numerals, 11 indicates a washstand or lavatory provided-with a suitable back 12 and a bowl 13.V In forming the lavatory, the bowl 13 merges into a fiat section 14 which is slightly inclined as indicated in Figures 2 and 3 so that water may freely flow therefrom into the bowl 13. The fiat section 14 also preferably merges intothe back 12 as indicated in Figure 3 so that the parts will be an integral structure. i

In order to iiush the bowl or clean the same, a specially constructed distributing member 15 is provided which is connected with the valve 16. A suitable supply pipe 17 is connected with the valve 1G so that when the valve 16 is turned on, water will be discharged into the distributing member 15 and from thence forced over the fiat section 14V as indicated by the arrows in Figure 1. It will be noted that the distributing member 15 is a tubular structure and merges into the casing 0f the valve 16, said tubular structure being Open at both ends and provided with a slot 18 extending the full length thereof so that a sheet of water will be discharged directly toward the bowl 13 and in addition a stream of wat-er will be forced in the opposite direction over the fiat Vsection 14. 4The water passing over the fiat section 14 will gravitate over the bowl by reason of the inclined arrangement and in addition by reason of the fact that the inclined section 14 is gradually reduced until it reaches the point 19. The point 19 is a dividing structure which causes the water to be discharged atthis point into the bowl.

In Figures 4 to 8 inclusive, will be seen a modified structure to that illustrated in Figures 1 to 3. In this forni of the invention the lavatory 11 is provided with a flat section 20 preferably horizontal and a substantially annular recess or notch 21 which is divided by the point 19. In this form of the invention the water is supplied to the valve 15 through a. pipe 22 connected with pipes 23 and 24 which in turn are connected with the hot and cold water pipes 25 and 26. In this way warm water is discharged through the valve 15 when the same is turned on. The casing' of this valve is preferably formed integral with a projection 27 which` merges into a tubular distributing member 28. said distributing member being open at both ends and provided with a slot 29 adjacent the bottom. The distributing member 2S fits into the groove or depression 21. as illustrated in Figures 4 and 6 so that when the valve 15 is turned on some Of the water will be discharged directly downwardly by reason of the slot 29 while the remaining water will be discharged laterally in oppositevdirections along the groove or depression 2l as indicated by the arrows in Figure el. This water will overflow into the bowl 13 and thereby thoroughly flushV each end and a slit facing the bowl and exand clean the bowl. l

After anyone uses the bowl, thesame may be readily cleaned by turning on the valve l5 which will quickly flush the bowl and `clean the same without any further effort on the part of the person operating the valve. If the bowl is flushed after each time it is used it will remain clean whereas if it is used and some of the soiled water is left standing, it will be necessary to use soap and otherrmeans for cleaning, which operation is entirely obviated by the complete flushing of all parts of the bowl and the surface 14.

Vhat I claim is l. A self-cleaning lavatory comprising a bowl formed with a flat platform surrounding the bowl adjacent its top and slightly inclined toward the same, said platform adjacent the front of the bowl presenting a restrictedarea to impede the flow of water V around the platform and compel the same to flow into the bowl all around its walls;

i and means for releasing the water on said platform.

Y 2. A self-cleaning lavatory comprising a bowl formed with a flat platform surroundingthe bowl adjacent it top and slightly inclined toward the same, said platform v adjacent the front of the bowl presenting a restricted area to impede the flow of water around the platform and compel the same point substantially circumferentially ofthe bowl for an appreciable distance, said tubular member having a discharge `opening at tending from one end to the other, and a valve member for turning on and off water to said tubular member. Y

3. In a self-cleaning lavatory, the combination with Va bowl formed with a substantially flat platform surrouiidingthe bowl at the top, of a tube extending along the rear edge of said flat platform for an appreciable distance and presenting open ends, and a slit extending between said ends, said slit facing the platform to permit the water emitted from said tube to form a running film of water around the edges of the bowl.

4. A self-cleaning lavatory of the character described, comprising a bowl formedV at yits top with a substantially annular recess tubular member. Y Y Y WILLIAM T. GUTl-l.
