PLUMBING SYSTEM Filed June 2, 1928 INVEVNTOR wmuwaw Patented Nov. 3, 1931 UNITED STATES PATENT OFFICE v WILLIAM C. GROENIGER, OF COLUMBUS, OHIO, ASSIGNOR OF ONE-HALF TO JOHN C.
' OROMWELL, OF ALLIANCE, OHIO PLUMBING sxs'rmr Application filed June 2, 1928. Serial No. 282,342.
'5 example as closet bowls for flushing purposes.
In the'copending applications of Groeniger and Cromwell, filed June 2, 1928, Serial Numbers 282,343 and 282,344, there are disclosed and claimed certain improvements in plumbm ing system and control valve therefor effecter referred to, adapted to comprise a portiontive for preventing aback flow of water from the waste receptacle to the water supply line.
The present invention relates to certain improvements in a system of the general characof a flushometer control valve, a fitting for insertion in the outlet connection from such valve, or a modifiedform of waste receptacle with which such connection communicates, the present invention contemplating the provision of an airadmission opening or openings in combination with water deflecting means cooperating therewith whereby the accidental escape of water through such opening or openings is prevented.
In the accompanying drawing, there is shown by way of illustration only, an embodiment of the present invention, it being understood that the drawing does not define the limits of my invention as changes in the construction and relationship of the parts disclosed therein may be made without departing either from the spirit of the present invention or the scope of my broader claims.
In the drawing: The figure is a vertical sectional view through a portion of a plumbing system including a flushometer valve with its inlet and outlet connections and a portion of a was te receptacle with which the outlet connection communicates.
Referring more particularly to theform of the invention illustrated in the figure, the water supply 2 is shown communicating with the inlet 3 of a fiushometer valve casing 4 having an outlet connection 5. The flow between the inlet and outlet is controlled in known manner by the valve assembly 6 adapted to be manually operated at will by the operating handle 7.
deflecting means 13 extending downwardly within the projection and in spaced relation thereto to provide an annular channel 14. The projection 12 may be provided with an opening or openings 15 adapted to establish a constantly open connection between the channel 14 and the atmosphere whereby at all times air is admitted into the system at a point on the outlet side of the valve in such manner as to preclude the possibility of a condition of vacuum within the connection 9 such as would be effective in siphoning any of the contents from the receptacle 10 upwardly therefrom through the valve and into the water supply system.
With the form of the invention illustrated in the figure, irrespective of the pressure under which water is discharged through the connection 1, the deflecting means 13 is op erative to prevent the back-flow of such water or the splashing thereof outwardly through the openings 15. It is essential, however, that the deflecting means 13 terminate at a point above the overflow line 16 of the waste receptacle as indicated in dotted lines in the drawing.
. It will be understood by those skilled in the art that the form of the invention illustrated herein is particularly adapted for use in substantially vertically extending connections wherein the water flow is downwardly and the velocity is such that a backing up of the water does not occur.
With the form of the invention illustrated, there is provided a system having a constantly open air admission opening intermediate the valve and Waste receptacle in combination with deflecting means operative to prevent the splashing of water from the system during the flushing operation. This constitutes one of the advantages of the present invention.
I claim:
1. A sanitary water flushing receptacle having a rim and an upstanding extension extending above the level of the rim by means of which flushing water is distributed to the interior of the receptacle from a source of supply, said extension having an interior integral water directing nozzle depending from the top thereof in concentric spaced relation to the inner wall of the extension to a plane above the overflow level of the rim, and a constantly open air port in the wall of the extension near the top and adjacent the side of the nozzle for obviating the possibility of the siphoning of the receptacle Water back into the source of supply.
2. A sanitary water flushing receptacle having a rim and an integral upstanding extension extending above the level of the rim by means of which flushing water is distributed to the interior of the receptacle from a source of supply, said extension having an interior integral water directing nozzle depending from the top thereof in concentric spaced relation to the inner wall of the ex tension to a plane above the overflow level of the rim, and a constantly open air port in the wall of the extension near the top and adjacent the side of the nozzle for obviating the possibility of the siphoning of the receptacle water back into the source of supply.
In testimony whereof I have hereunto set my hand.
WILLIAMC. GROENIGER.
