DISCHARGING NOZZLE FOR WATER CLOSETS.

DIscHAIteING-NozzLn non. WATER-GLOSETS.

I Water-Closets, of which the following is a specification. I 7

My invention relates tonozzles for discharging water into the upper portion of a water closet hopper or bowl. r

The difliculty heretofore has been to provide a discharging nozzle which would cause the water to spread so as to extend entirely around the interior surface of the hopper or bowl and in running down said sides cleanse all parts or portions of the inner surface thereof.

My invention has for its objectto provide a simple and eflicient nozzle which will cause the water so to spread as it is discharged therefrom that it will completely cover the entire interior surface of the hopper or bowl and efliciently cleanse the same, thereby overcoming the objections and deficiencies previously noted.

In the accompanying drawing I have illustrated one form of .a convenient embodiment of my invention; but it will be understood that changes may be made in the de tails of construction within the scope of the claims withoutv departing from my invention.

In the drawing,-Figure 1 is a view partly in top plan and also partly in transverse horizontal section of a water closet hopper or bowl and showing also the top plan of a nozzle in position embodying my invention. Fig. 2 is a' vertical longitudinal section on the line 2-2 of Fig. 1; Fig. 3 is a bottom plan view of a, nozzle embodying my invention with the opposite end portions shown in longitudinal section; andFig. 4 is a transverse central sectional view taken on line 44 of Fig. 3.

Referring to the drawing, 1 designates a water closet hopper or bowl and 2 the top rim of the same formed by an lnwardly and downwardly curved portion of its upper I Specification or Letters'latentf Patented J true 8, 1915.

Application filed August 23, 1913. Serial No. 786,231.

2 at the top of the hopper and at the rear side of same. The curved pipe or tubular member 3 is provided, adjacent to its opposite ends and upon its upper sides, with lugs or projections 4 which rest against the inner surface of the rim when said nozzle is in position. 1

The opposite ends of the pipe or tube 3 are cut, as'shown at 5, diagonally with respect to the axes of its end portions. The openings in the ends of the pipe or tube '3 are restricted by means of the interior lugs or projections 6 formed therein and extendingcrosswise theretofore and forming what may be termed and regarded as a dam.

The pipe or tube 3 is provided at its central portion or section with a downwardly projecting relatively wide and hollow portion 8 having a narrow slot therein extending generally in the direction of the pipe or tu e. I I A screw threaded boss or projection 10 is formed upon the rear side of the projection 8 to which a coupling 11 is secured by means of which the pipe. 12 is connected with the nozzle so that water which is received from a flush tank (not shown) may enter the chamber into projection 8 and passtherefrom into the pipe or tube 3, flowing toward and being discharged from both'ends.

It will be observed that the narrow slot, 9 extends up through both sides of the projection 8 to points partially coincident with the interior of the surface of the lower part of tube 3. By reason of this arrangement water escapes from said slot not only from the bottom of the projection 8 but from points entirely around what may be termed the end of the said projection. Simultaneously with the escape of water through slot 9 the water also escapes from the constricted openings in the ends of the pipe or tube. By reason, however, of the presence of the lugs "or projections 6 which extend across the said ends,

the unrestricted flow of water from the ends of the said pipe or tubes is prevented. The result is that the water from the said open ends is projected therefrom around the front side of the bowl or hopper a distance greater than would otherwise be the'case, causing the converging streams of water to meet at the front side of the hopper or bowl.

Owing to the fact that the openings in the ends of'the pi eor tube 3' are restricted by thepresence o the lugs or projections 6,

the flow of water from the said pipe or tube through the open ends is retarded with the result that the water is forced through the i struction of nozzles above described andv illustrated in the accompanying drawings I cause the stream of water from the several discharges to open and meet and entirely cover the interior surface of the hopper so i g as to cleanse each and every portion thereof.

I claim i 1. A nozzle for flushing water closet apparatus consisting of a tubular member hav ing a relatively flat projection at its central portion to which water is supplied from a flush tank connection and the said projection having a slot in the bottom and side walls thereof which slot extends in the direction 7 of the length of the said tube, the size of the openings in the. ends of the said tubular member being less than thetransverse area of the interior of said tubular member at a distance from said open ends whereby the discharge of the watervfrom the said open ends is retarded and restricted, the water which is discharged from the slot in the said projection being discharged down wardly and also laterally, the laterally flowing portions meeting and combining with the water discharged from the ends of the said tubular member, whereby they entire surface of the water closet hopper or bowl is covered.

2. A nozzle for flushing water closet apparatus, consisting of a curved tubular member having. a relatively fiatdownwardly eXtending projection at its central portion, the said projection being provided with 'a slot through its bottom and side portions, said 7 slot being situated in a plane extending in the direction of th'elength of the saidtubular member "and the said member having openingsinits opposite ends and having the water portion, to which water is suppliedfrom flush tank connection and the said projection havinga slot in the bottom and'side walls thereof'which slot extends in'the direction of the length of the said tube, the said tubular member having open ends and also having means situated in the said open ends for partially closing the said openings and'retardin'g the flow of water therefrom,

the water which is discharged from the slot in the said projection "being discharged downwardly and also laterally, the laterally flowing portion meeting and combining with the water discharged from the'ends of the said tubular member, 'wherebythe entire surface of the Water closet hopper or bowl is 7 covered. v g

In testimony that I claim the foregoing as my invention, I have hereunto signed my name this 20th day of August, A. D. 1913.
