WILLIAM SYDNEY GRAHAM, OF CHICAGO, ILLINOIS, ASSIGNOR TO FEDERAL-HUBER COMPANY, OF CHICAGO, ILLINOIS, A CORPORATION.

WATER-CLOSET.

Specification of Letters Patent.

Patented May 9, 1916.

To all whom it may concern:

Be it known that I, IVILLIAM SYDNEY GRAHAM, a citizen of the United States, and resident of Chicago, in the county of Cook and State of Illinois, have invented a certain new and useful Improvement in Water- Closets, of whichthe following is a description, reference being had to the accompanying' drawing, which forms a part of my specification.

My invention relates to the bowl of a water-closet and consists in a novel and improved means for flushing the same, whereby a quick and thorough action is obtained as will-be apparent from the following described construction.

In the drawing :Figure 1 illustrates my invention applied to a bowl having a downward discharge-passage; the figure be ing a vertical sectional view taken through the center of the bowl. Fig. 2 is a horizontal sectional view taken on the line. 2-2 of Fig. 1. Fig. 3 illustrates a wall type of closet, and Fig. 4 is a sectional elevation of a prison type.

Throughout the several figures, like reference numerals have been used to designate corresponding parts.

The invention exists in a bowl provided with a discharge-passage in combination with a particular type or character 01E jet that will quickly move the water through the discharge-passage in substantially a solid column and thereby entrain and carry with it the entire contents of the bowl and discharge it through the outlet or dischargepassage; 3, further feature of the invention being the arrangement of the diiierent water-passages whereby the in-rush of air into the stand or down-pipe of the source of supply will be prevented after the closet has been flushed, as will more clearly appear from the following description.

A, represents the closet-bowl, provided with the discharge-outlet, comprising the up-leg or diScharge passage b, and, in the particular style of closet illustrated in the drawing, the down-leg or discharge-passage c; the relation between them being such that a water-seal is formed, as is usual with the conventional forms of bowls employed today. The water from a source-of supply is admitted to the bowl through opening B, which communicates with the circumfer: ential or rim chamber C by means of the ramifications or passages 03, which preferably extend down below the top of the wall separating the up-leg from the down-leg of the discharge outlet, in other words below the water-line or seal of the closet; and then upward to the chamber C as shown by dotted lines in Fig. 1. At any suitable point, passage d is provided with a branch or passage 6 which communicates with the elongated circular chamber D, which ex tends between the up and down leg of the outlet. Extending from chamber D out into the up-leg b of the discharge is a circular et-opening or series of openings f. The circumferential chamber C has the usual passage or port 9 extending about the bowl whereby the water entering chamber C will be allowed to flow down adjacent the wall of the bowl as is usual and apparent from the construction illustrated.

The watersupply admitted at B, passes down through passages 03, part of it passing up through passage d into rim-chamber C and thence through the orifices or ports of said chamber to the interior of the closetbowl, while the remainder of the supply passes through passage 6 into chamber D and through the orifices or circular ports f, which may be one continuous opening or a number of openings arranged in a circle, into the up-leg of the discharge. The nature and position of the circular port or ports f is such that a circular spray of water will issue into discharge-passage b and directed in such manner as to converge at a point above, thereby producing a force that will cause the water to move in a somewhat solid column through the passage which will entrain and draw With it all the contents of the closet-bowl, causing a complete and positive flushing of the bowl.

By having the water-passages communicating with the rim-chamber C formed as shown and described, to withaving the passages dip down below the water-seal or level in the bowl-which extends up to the horizontal plane occupied by the top of the wall between the up and down leg 'or passage of the discharge-outlet-it is evident that a water-seal will also be formed in the passage (Z. This seal will prevent the air from rushing through chamber G, into opening B and into the pipe leading from the source of supply as would be the case if a direct connection was had between chamber C and opening B, as is true with the constructions heretofore used. By the use of my construction it is apparent that air cannot rush into the pipe, to be displaced when the closet is again flushed and thereby cause undue noise in addition to the displacement of the foul air that has entered the chambers and pipe leading to the source of supply.

I have illustrated my invention applied to a conventional form of closet having the short or up leg and the long or down leg, but it is apparent that the invention is also applicable to the wall form of closet as shown in Fig. 3, or to the prison form of closet, as shown in Fig. 4, wherein the long or down leg is omitted and the discharge is in a horizontal direction to the soil-pipe.

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

1. A water closet bowl having a discharge passage which opens horizontally and is provided with an up-leg, a chamber encircling said passage at its lower end where said passage communicates with the bowl proper, passages leading from said encircling chamber into the lower part of said upleg and converging to produce a body of water issuing from the chamber and hav ing its center of convergence in the central line of the upleg, a conduit on either side of said passage leading to said encircling chamber for supplying water thereto, an intake disposed centrally above said discharge passage and communicating with both of said side conduits, a hollow rim for said bowl, and auxiliary conduits one on each side of said discharge passage, said conduits dipping below the normal water level of the bowl to form a water seal for the hollow rim.

2. A water closet bowl having an up-leg leading to the rear discharge opening, the upleg having a restricted inlet opening, a chamber encircling the restricted portion of the upleg and having oppositely disposed jets leading therefrom into the upleg at the end of the restricted portion thereof, and a conduit for supplying water to said chamber.

3. A water closet bowl having an up-leg leading therefrom, the inlet end of the upleg being less in diameter than the outlet end thereof, an elongated chamber at the rear of the upleg having its lower end encircling the inlet end of the upleg, the upleg having a plurality of jets formed therein at the end of the restricted portion thereof and communicating with the said chamber, and an intake duct leading to the elongated chamber for the purpose specified.

4. A water closet bowl having a discharge passage with an upleg, the inlet end of the upleg being less in diameter than at the outlet end thereof, the angular wall formed within the upleg and having a plurality of jets formed therein out of the path of the discharge through the upleg, a chamber encircling the restricted portion of the upleg and communicating with said jets and a water supply leading to the chamber for the purpose specified.

5. A water closet bowl having a discharge passageway with an upleg, jet openings positioned within the up-leg, a chamber communicating with said jet openings and surrounding said upleg, a circumferential rim chamber, an inlet port, V-shaped ducts leading from the inlet port and communicating with the circumferential rim chamber, and the apex of each duct being in communication with the chamber, whereby water will be supplied to the jets for the purpose specified.

6. A water closet bowl having a hollow rim and a discharge passage including an upleg, a water inlet at the top of the bowl, a chamber surrounding the bottom of the upleg, conduits formed integrally with the bowl and leading from said inlet to said chamber, opposed jets arranged about the bottom of said upleg and in communication with said chamber, whereby the entire body of water in said upleg will be moved upwardly therein, and conduits connecting said inlet with said hollow rim, all for the purpose described.

In apparatus of the class described, a water closet bowl having a hollow rim, a discharge having a horizontal portion, an intake above said discharge, an upleg communicating with said discharge, said up-leg having an enlargement adjacent its lower end to form one side of a water conducting conduit whereby water is led from the intake to the upleg and opposed jets at said enlargement whereby water in the leg is forced in a column or plug into the discharge.

8. A water closet bowl comprising a one piece structure having a hollow upper rim, an intake substantially in a plane with said rim, a discharge below said intake, an upleg leading to said discharge comprising a shell continuous with the bowl, a chambered enlargement around said upleg, a conduit from the intake to said enlargement, jets arranged about and leading upward from the lower end of said enlargement whereby the water flowing through said conduit is discharged up said upleg and causes the water therein to flow out of the discharge, and upwardly directed conduits beginning below the water seal and leading from said enlargement to said hollow rim.

9. A water closet bowl having a hollow rim and a discharge passage including an up-leg, a water inlet adjacent the top of the bowl, integrally formed conduits leading from said inlet to a point adjacent the bottom of the up-leg and discharging at said copies of this patent may be obtained for five cents plurality of jets into the up-leg, integrally formed conduits in com- 10 munication with said first mentioned conduit and leading to the hollow rim.
