WILLIAM U. GRIFFITHS, OF PH ILADELPHIA, PENNSYLVANIA. I

FLUSH-CONTROL MEANS FOR WATER-CLOSET HOPPERSI Application filed May 17,

In the flushing of water closet hoppers no practical means heretofore has been found by which the water could be supplied to the hopper in proper quantity and at proper speeds to effect the washing of all sides of the hopper without at the same time permitting its delivery in such quantities and at such speeds as to produce objectionable splashing above and over the edges of the hopper.

The general object of my invention is to provide means of novel construction for controlling the delivery of water to a water closet hopper for flushing and cleansing the same.

a In order that the invention may be readily understood and its practical advantages fully appreciated, reference may be had to the accompanying drawing in which I have illustrated one form of embodiment thereof.

However, it will be understood that the invention is susceptible of embodiment in other forms of construction than that shown and that changes'in the details of construction may be made within the scope of the claims without departing from the said invention.

In the drawing, Fig. 1, is a view in central vertical section of the rear upper portion of a water closet hopper provided with means embodying my invention; and Fig. 2 is a View in perspective of the device embodying the invention, separated from the hopper.

In the drawing, I have shown a hopper 1 provided at its upper edge with a rim 2 having an inwardly and downwardly extendlng skirt or flange portion 3. The rim 2 with its skirt 3 cooperates with the adjoining portion of the hopper 1 to provide a channel through which water flows around the upper edge of the hopper and from which channel the water is discharged downwardly upon the sides of the hopper to cleanse the same.

The hopper is provided at its rear side with a lateral or outwardly extending tubular projection 4 upon which a nozzle embodying the invention is mounted. The said nozzle comprises a tubular portion 5 having a laterally extending flange 6 which is located about the middle of its length. The said flange is adapted to be secured to the outer end of the tubular projection 4 by means of screw threaded bolts 7. The joint between the flange 6 and the end of the tubular projection 4 is rendered water tight by means of a washer 8 of any suitable material. The inner end of the tubular section or portion 5 is provided with a crosswise extending wall said flange to the outer 1927. Serial No. 191.948.

10 which is located substantially at right angles to the axis of the said section. To provide for the passage of water from the tubular section 5, Ihave provided the same with a transverse slot or opening 12 located in the upper portion thereof, as shown in the drawing.

The outer end portion of the tubular sect1on 5 out-side of or beyond the flange 6 is screw threaded for the purpose of connecting the nozzle to the lower or delivery end of a pipe having connection at its opposite end to a flush tank or other water supply. Neither the sald pipe nor the flush tank is shown.

I have found that when a nozzle of the construction of that disclosed herein embodying my invention is employed, water in suflicient quantity for the flushing and cleansing of the hopper is discharged therefrom but without splashing of the same above or over the top of the hopper and also without disagreeable and noisy rushing and gurgling sounds.

Having thus described my invention, what I claim and desire to secure by Letters Patent is:

1. A. water closet hopper provided at its upper rear side with a rearwardly extending tubular propection, the said projection having mounted thereon a nozzle which projects partly thereinto, which nozzle comprises a tubular section having a laterally and outwardly extending flange located about the middle of its length, means for securing the end of the said tubular projection, and the inner end of the said tubular section of the nozzle terminating in a wall which extends at right angles to the axis of the said section, and the said section being provided with a transversely extending slot at its upper side in adjoining relation to the said wall.

2. In combination, a water closet hopper, provided at its upper rear side with a rearwardly extending tubular projection, a. nozzle having connection with said projection and.

extending partway thereinto, the said nozzle terminating at its inner end in a wall which extends transversely of the axis thereof, and the said nozzle being provided with a transversely extending slot at its upper side in adjoining relation to the said wall, and a skirt supported upon the said hopper, which skirt extends across and in front of the inner end of the said tubular projection and being located in proximity to said inner end, substantially as described.

3. In ,comloination, a, water closet hopper, provided at its upper rear side W1tlnareartends partway into said tubular projection and terminates at its inner end in a Wall" which extends transversely-of the axis thereof, and the said section being provided with a. transversely extending: slouin adjoining relation to the said walL-thesaid slotperniitting the discharge of water from the said tubular section laterally into the said tubular projection on the said hopper.-

In testimony that I claim the foregoing as my invention, I "have hereunto signed my name this 1(ifl1da, .of May, A. D. 1927.
