7 Claims.

Thisinvention relates to an improved means for securing a flush tank upon the shelf of a closet bowl, and is a application,

Serial No. 131,604, filed March 18, 1937, entitled Combined closet bowl and tank structures.

' An object of the invention is to provide improved securing means of a simple, efficient nature that will be readily accessible and can be more easily adjusted in connecting the tank to 0 the closet bowl shelf.

Another object of the invention is to provide improved means for securing the tank to the,

owl shelf, which will avoid the necessity of providing an opening in the bottom wall of the hollow shelf and the provision of packing at this point,-and which will be positioned wholly within the hollow shelf.

The invention, with other objects and advantages thereof, and the particular construction, combinations and arrangements of parts comprising the same, will be understood from the hereinafter contained detailed description, when considered in connection with the accompanying drawings, forming part hereof and illustrating two embodiments of the invention.

In the drawings: V

Figure 1 is a vertical central section through adjoining parts of a water closet bowl and tank a structure constructed in accordance with the present invention;

Figs. 2 and 3 are fragmentary perspective views of gaskets employed respectively between the flush valve structure and tank outlet, and between the tank outlet and bowl inlet;

Fig. 4 is a detailed sectional view on the line 4-4 of Figure 1, looking downwardly;

Fig. 5 is a vertical transverse section on the line 5-5'of Figure 1, looking in the direction of j the arrows; .40 Fig. 6 is a horizontal of Figure 1; I, V

Fig. 7 is a vertical section from front to rear through the joint and adjoining closet bowl and tank parts'of a modified construction, 'andg Fig. 8 is a section on the line 8-8 of Figure '7.

While two specific embodiments of theinventionare illustrated in the drawings it will of course be understood that minor changes and modifications may be made in the particular constructions shown, and'the invention may be embodied in other forms; as will appeal to those I skilled in the art and falling within the scope of the app-ended claims, without departing from the spirit of the invention.

Referring to a detailed description of the par-,

section on the line 6-5 the top and bottom walls this application June ticular embodiment of the invention illustrated in Figures 1 to 6 of the drawings, l designates the water closet bowl provided with a rearwardly extending hollow shelf having a top wall 2, and side walls 3, 4 and 5, the latter being continuous with the rear wall 6 of the downleg of the syphon, and the wall 1' of the syphon forming the bottom wall of the shelf. The top wall 2 of the shelf is provided with an opening 8. Forwardly of this opening, the shelf has a transverse rib 9, and to the rear of the opening at either side are raised portions 59.

ll designates the flush tank supported on the shelf on the transverse rib 9 and raised portions H] with the opening H in its bottom aligned with the opening 8 of the shelf. Within the tank is a conventional flush valve structure 52 having the threaded portion i3 projecting below the bottom of the tank. l i designates a rubber gasket interposed between a flange IS on the valve structure and the bottom wall of the tank, and I 6 is a gasket between the top wall 2 of the shelf and the bottom of the tank. The valve structure i2 is held in place by a threaded tubular coupling member or sleeve il at the exterior of the tank engaging the threaded portion 13 of the valve structure. The coupling member, which is open at its sides, is shown as comprising a threaded sleeve portion it? with spaced depending arms I 9 joined at their lower ends by a transversely extending centrally apertured plate portion 20.

Means for securing the flush tank H to the hollow shelf is provided comprising a bolt 2i and nut 22 cooperating with the coupling member l1 and with an anchoring wall portion 23 located within the hollow shelf, said wall portion being joined to the side walls 3, 4, 5, of the shelf and extending horizontally in spaced relation with of the shelf below the coupling member ll. The anchoring wall portion may be and preferably is provided, as shown, with water passages 23. The bolt has an elongated rectangular shaped head 24 and is detachably engaged with the anchoring wall by passing the head 24 of the bolt through a correspondingly shaped slot 25 in the anchoring wall. The bolt extends upwardly through the aperture in the transverse plate portion 20, and the nut 22 fits against the upper side thereof. The nut is provided at the topwith a transverse slot 26 for engagement by a screw driver in adjusting the same. Lugs 21 are provided on the under face of the anchoring wall 23 to prevent turning of the bolt. As will be understood, in assembling the parts, the bolt 2| is first engaged with the anchoring wall 23, the coupling member ll connected with the valve structure is threaded over the shank of the bolt, and the nut 22 is then put on the bolt and turned up to securely clamp the parts together, the adjustment of the nut: being readily accomplished from the interior of. the tank II.

It will be noted that by the special construction and arrangement of parts hereinbefore set forth means of a simple, efficient nature is provided for securing the tank to the shelf of the closet bowl. The securing means is readilyaccessible in assembling and for adjustment, and

the necessity for providing an opening in the bottom wall of the hollow shelf with accompanying packing is avoided.

In the modified construction illustrated in Figures 7 and 8 of the drawings, the means forsecuring the tank to the shelf of the closet bowl is similar to that hereinbefore described to the extent that it provides for more easy access thereto but in this construction the fastening bolt is engaged with the bottom wall of a shelf instead of an anchoring wall located within the same. In Figures 7 and 8, 28 designates the water closet bowl provided with a hollow shelf 29. 39 is the tank, 3! the valve structure, 32 the tubular coupling member connected with the valve structure, and 33 and 34 the securing nut and bolt, the latter in this instance having laterally projecting lugs 35 engaging slot 36 in the bottom wall of the shelf to hold the bolt against rotation during the adjustment of the nut, which, as in the construction illustrated provided with a slot 31 in the top thereof for engagement by a tool to turn and thereby lock the assembled structure.
