J. M. TEAHEN WATER CLOSET Feb. 13, 1940.

Filed Oct. 18, 1937 INVENTOR JAM ES M.TEAHEN ATTORNEYS ..UNITED 'STATES Patented Feb. 13, 1940 I 'PATENT OFFICE- The invention relates to water -clcsets of that type in which the tank is separate from the bowl but directly supported thereon. With such constructions the water discharged from the tank passes directly into the bowl but a separate inlet conduit is required. Also, it is necessary to provide suitable means for firmly attaching the tank to the bowl. With my improved Construction I employ the inlet Conduit as a, tie connection for 0 securing the tank to the bowl and I also preferably combine this with ,the fitting which forms the seat for the outlet valve. The invention, therefore, consists in the above novel features of Construction, together with certain additional features as` more fully hereinafter set forth.

In the drawing: V Figure 1 is a'- vertical through the water closet;

Figure 2 is a plan View thereof; Figure 3 is a cross section on line 3-3 of Figure 1'. v

A is the bowl which ma be of any 'suitable construction excepting as hereinaiter described. B is a hollow shelf integral with the bowl and projectingrearward therefrom. C is a hollow rim at the top of the bowl which is connected 'with the space within the hollow shelf and is provided on its underside with a series of jet apertures D. E are partitions' within the rim C formingtherebetween a chamber F located at a point diametrically opposite the hollow 'shelf B. The partitions E are provided with comparatively shallow but wide ports E' extending through the top portions thereof forming communication be-, tween the'chamber F and other portions of therim. There is also an elongated discharge port F' communicating with the chamber F through the bottom thereof. The Construction just described isgone in which 'air within the hollow rim may be displaced by incoming water ,from the hollow shelf with the avoidance of noise.

G is the tank which rests upon the shelf B and extends on opposite sides thereof. The bottom G' of this tank hasa port G therein which registers with an opening in' the top of the hollow shelf and forms` a passage. This permits the flow of water from the tank through the hollow shelf into the rim C from which it is discharged through the ports D, the air having first been displaced through the ports' E' and F'. The tank G is further provided in one wall thereof with an overflow passage G the top of which is slightly above the normal level of the water in the tank, while the bottom registers with a port B' 55 in the hollow shelf. v

longitudinal section' To securely attach the tankto the bowl and at the same time to forma water inlet connection to the tank I employ a fitting H; The upper end of this fitting has an annular portion H' which surrounds the port (3: and forms a seat for the outlet or fiush valve, not shown. Centrally within this annular portion and connected thereto by hollow spokes I-I is a spud H which passes downi ward through the port Gr and through an aperture in the lower wall of the hollow shelf B; The lower end of this spud is threaded to receivea clamping nut I for drawing the fitting down upon the tank and clamping the latter to the shelf. A scaling gasket J `is placed between the nut I and the bottom of the shelf and an annular gasket K is inserted betweenthe seat portion H' and a conical wall of the aperture (3 Below the nut I there is a sufiicient extension of' the threaded portion for securing to the spud the water inlet Conduit. A gasket K' between the tank and the shelf seals about the portsG and B';

The specific Construction of the water inlet and outlet valve which cooperate with the fitting just described forms the subject matter of another application for patent Serial No. 104557, filed October 7, 1936, and I will, therefore, omit description of such parts. It will be sufiicient to state that an inlet valve L of the flexible diaphragm type is arranged within the portion H and' the Water passing said valvel when open; fiows through the hollow spokes H into the tank. Also, the water is normally retained in the tank by "a flush valve M seated on 'the member H'. My invention is not, however, confined 'to this specific Construction, but may be used with any type of water inlet which also constitutes a tie connection for securing the tank to the bowl.

The tank G' is preferably formed with a top portion Gr which is integral with' the side walls and which covers a large' portion of the interier of the tank; There is, however, a central opening G which is of sufficient size to admit the fit-- tings and which is normally closed by a cover G It is the usual practice to form tank covers of dimensions slightly in excess of 'the length and width of the tank, so as to overlap the' side and end walls thereof. On account of the' thickness of the cover required to impart to the same the necessary strength, it adds a considerable amount to the weight of the tank. Withmy improved construction the integral part of the top may be formed relatively thin as it is reinforced by its union with' the side and end walls. Also, the detachable cover is sufficiently smallin area not to require a, great thickness. consequently,

the total weight of the tank and cover is considerably less than with constructions of tanks having the same Capacity, as heretofore made. This is. particularly advantageous Where the tanks are made of vitreous material.

What I claim as my invention is:

1. In a water closet, the combination of a bowl having a hollow shelf extending rearward therefrom a. tank supported on said shelf provided With an outlet port through the bottom thereof registering with a corresponding port in said hollow shelf, and a combined inlet and outlet fittng having a seat portion for a water discharge valve surrounding the port in the bottom of the: tank and a central water inlet Conduit passing through said port and the bottom of said shelf' andformv ing a tie connection between the tark and bowl.

2. In a water closet, the combination of a bowl having a rearward extension, a tank Testing on said extension, and a water supply Conduit for said tank passing centrally through said extension and the bottom of* the tank' forming the sole tie connection therebetween. v 3. In a Water' closet, the combination of a tan water inlet fitting. passing through said' hollow shalt and bottom of the tank within said annular gasket and forming a means for securing said tank on said shelf.
