ATTORNEY Illl'IIIII1!J United States Patent TOILET TANK, BOWL, AND ADAPTER CONNECTION Angelo Minella, Houston, Tex., assignor to A. Minella Plumbing Supplies, Houston, Tex.

Application October 1, 1956, Serial No. 613,085

6 Claims. (Cl. 4-68) This invention relates to a toilet tank and bowl, and man adapter connection therefor, and to a method of connection whereby tanks of various makes having connection openings in the bottom thereof variously spaced "from the discharge opening centrally therein, may be assembled with toilet bowls of various makes having connection openings in the top thereof variously spaced from the inlet opening therein.

It is therefore a primary object of this invention to ;provide toilet tanks, toilet bowls, and adapter connections therefor, and a method of connection whereby toilet tanks of various makes may be assembled with toilet bowls of various makes by virtue of tank and/or bowl construction and adapter connections therefor.

It is another object of this invention to provide such a construction and method, whereby adapter connections may be made between tanks and bowls of various makes with a minimum effort, and a minimum of special equipment.

Other and further objects will be apparent when the specification herein is considered in connection with the drawings in which: 1

Fig. 1 is an elevation of an assembled toilet tank and bowl modified in accordance with this invention;

Fig. 2 is a bottom view of a tank modified in accordance with this invention;

Fig. 3 is a plan view of a bowl modified in accordance with this invention;

Fig. 4 is a longitudinal sectional elevation of an adapter connection for adapting the toilet tank of Fig. 2 to a conventional toilet bowl;

Fig. 5 is a transverse sectional elevation taken along section 5-5 of Fig. 4;- and Fig. 6 is an elevation of the special bolt included in the. adapter.

Referring in detail to the drawings, a tank 11 is shown in Fig. 1 installed upon a bowl 12, both tank and bowl being of conventional toilet size and construction except as hereinbelow described as to novelty. In the bottom view: of the tank shown in Fig. 2 a central discharge passage or outlet or opening 14-is shown centrally of the bottom or base closure'15 of the tank, and equally longitudinally spaced on either side thereof slots 16 are provided in the base or tank bottom. Also the bowl 12 shown in Fig. 3 has a central passage or inlet 17 therein in the top 19 thereof and equally longitudinally spaced on either side thereof slots 18 are provided.

In practice it often happens that because of strikes, priorities and scarcities during emergency periods, or in booming building periods, it is not always possible to obtain the same make of toilet tank and bowl for assembly, with the consequence that a bowl of one manufacturer must be assembled with a tank of another manufacturer. :In such cases the conventional round openings conventionally provided in tanks and bowls in place of the;

slots

16 and 18 hereinabove described may vary in spacing from the

central opening

14 or 17, respectively so that the round openings in tank base and top of bowl ice do not coincide. Obviously, as set forth within the scope of. the preceding sentence, connection may be made when the tank has slots while the bowl has only round holes or openings, or conversely when the bowl has slots while the tank has only round holes or openings.

In such case the material, usually procelain, of which tank and bowl are constructed does not readily lend itself to permitting extension of such round openings to provide coincidence between such tank and bowl openings, with the consequence that it is often diificult to assemble toilets and bowls when provided by different manufacturers having different spacing practices.

In order to accomplish the adaptation of the tank of Fig. 2 to a bowl, as shown in Fig. 3, or to a conventional bowl, an adapter or adapter connection as shown in Figs. 4-6 is provided. Such an adapter 20 comprises a slot insert 21 having a flange 22 of larger area than the slot 16 to fit therearound on a gasket 23 and a bolt head support 24 comprising two (2) oppositely facing sections of L-shape cross-section depending from the flange 22 and spaced apart slightly more than the diameter of a connection means or bolt 25, the head of which is insertable in the slot 26 provided between the Ls, so that the head 27 of the bolt shoulders on the upper faces of the lower legs of the Ls. The head 27 is elongated to extend in one direction substantially beyond'thebody or shank of the bolt 25 to bear upon the Ls.

As is conventional, the end of the shank of the bolt 25 is threaded and receives a large washer 28 thereover of size to bear upon the inner face of the bowl top 19 surrounding the opening 18. Optionally, another smaller friction washer-29 may be inserted over the end of the bolt 25 to bear against the washer 28; then when a nut 30 is threaded on the bolt end to bear on the washer 29, the whole. adapter is tightened so that the friction of the flange 22 bears tightly against the top of the gasket 23 to force its lower face tightly against the top surface of the tank bottom 15.

As best seen in Fig. 6, the elongated bolt head 27 has the lower surface thereof to extend downwardly at an angle to the horizontal so that when the nut 30 is tightened the outer end of the bolt head 27 exerts a downward tension on the upper faces of the lower legs of the support Us 24 to firmly bind the tank bottom and bowl top in firm and sealed abutment.

Variation may be had in construction, for instance, the adapter 20 may be installed in the toilet bowl slots 18 in inverted position from the position shown in Figs. 4 and 5. Obviously in such case the washer 28 will bear against a gasket corresponding in function with the gasket 23 and such gasket in turn willbear against the upper face of the tank bottom 15 on either side of each to effect the binding abutment between tank bottom and bowl top as the cap screw is threaded into a selecte tapped hole in the support 24.

Broadly, this invention is not limited to the structural embodiments and method of connection herein disclosed, but other embodiments and modifications are considered as well as such may fall within the broad spirit of the invention and within the broad scope of interpretation claimed and merited for theappended claims.
