United States Patent 3,336,602 FLUSH TANK TOILET Theofile T. Kubit, 7430 Meadow Lane Drive, Cleveland, Ohio 44134 Filed Feb. 5, 1965, Ser. No. 430,622 9 Claims. (Cl. 4-97) This invention relates to flush tank toilets and more particularly aims to provide such a toilet having a separate urinal bowl adjacent the main bowl, and means for separately flushing the urinal bowl and the main bowl.

The flushing of a tank type toilet such as commonly used in residences and other places requires the utilization of five gallons or more of water for each flushing operation. Since in the majority of instances the toilet i used merely for urination and not for disposition of fecal matter, it would seem that the utilization of such a large quantity of water for each flushing in cases where the bowl has been employed for urination only, constitutes not only a waste of water but a large expenditure for the utilization of such quantity of water which could possibly be minimized.

With the foregoing in mind it is a principal object of my invention toprovide such a flush type toilet in which a much smaller quantity of water may be utilized for flushing in those instances where the toilet has been used for urination only.

A further object of the invention is to provide a flush tank toilet of generally conventional type which is capable of being used for all usual purposes and which is provided with a separate urinal section within the main bowl section and is further provided with separately controlled means for selectively flushing either the urinal section only or both the urinal section and the main bowl section at the same time.

My present invention, therefore, contemplates the provision of a toilet comprising a flush tank and a bowl section having a main bowl, a urinal bowl adjacent the main bowl, and means for selectively flushing and separately flushing either the urinal bowl only or both the urinal bowl and main bowl at one time and by the utilization of a single flush tank of generally conventional type. For the latter purpose, my invention contemplates the provision of conventional outlet means at the bottom of the flush tank communicating with the main bowl for flushing the same in a generally conventional manner. My invention further provides however, a second outlet means from the flush tank at a higher level than the first outlet means, the said second outlet means communicating with said urinal bowl for flushing the same, and a separate valve means for controlling outflow of liquid from the said second outlet means of the flush tank. The separate valve means for controlling the outflow of liquid to flush the main bowl and to flush the urinal bowl are each of the same generally conventional type.

For the purposes of flushing both the urinal bowl section and the main bowl section at the same time, means is provided for conducting liquid from the bottom tank outlet to both the main bowl and the urinal bowl section.

A further advantage arising from the use of my invention is that the urinal bo'wl section is normally dry and hence quieter in use for urination than is the main bowl for the same purpose since the latter contains a quantity of water therein.

Other features, advantages and objects of the invention will become apparent from the following detailed description taken in conjunction with the acocmpanying drawing, in which:

FIGURE 1 is a top plan view of a flush tank toilet embodying my invention.

3,336,602 Patented-Aug. 22, 1967 FIGURE 2 is a sectional view taken about on the line 2-2 of FIGURE 1.

FIGURE 3 is an elevational view of the flush tank, portions being shown in section.

Now referring to the drawing and describing the invention in detail, the letter A generally designates the flush tank section and the letter B generally denotes the bowl section of a toilet, both sections being of generally conventional design of flush tank type toilets commonly used in residences and elsewhere. The upper rim of the bowl section B is of conventional channel form providing a conduit for liquid and extending all the way around the periphery of the upper rim thereof. The said channel formation, denoted by the numeral 1, is disposed inwardly of the bowl section around the upper periphery thereof providing a conduit 2 therewithin which is in communication with the main outlet pipe 3 in communication with the discharge opening at the bottom of the flush tank 4. Said discharge opening is provided with the usual valve seat 5 and is adapted for seating engagement thereon of a conventional rubber valve member 6. The lower extremity of the channel formation 1 is provided with a plurality of apertures 1a adjacent the interior bowl surface so as to permit liquid to be carried around the conduit 2 and also to flow out through the apertures 1a and thereby flush down the sides of the bowl in the usual manner when the valve member 6 is lifted from its seat to permit discharge of liquid from the flush tank 4 through the outlet pipe 3.

The bowl section B provides a main bowl 7 and a separate urinal bowl 8 somewhat smaller than the main bowl and disposed within the latter at the forward portion of the bowl section B.

The said main bowl 7 is provided with the usual discharge opening 9 in the lower portion thereof which communicates with the conventional siphon trap 10 which serves to maintain a normal liquid level represented by the dotted line 11 within the main bowl 7, the liquid in the bowl 7 and trap 10 being discharged therefrom to and outwardly through the discharge pipe 12 by siphon action through the trap 10 during the flushing operation of the main bowl.

The urinal bowl 8 is similarly provided with a discharge opening 13 likewise communicating with a siphon trap 14 which in turn communicates with a branch discharge pipe 15 leading into and communicating with the main discharge pipe 12. The siphon trap 14 is preferably designed to maintain a normal liquid level therewithin, which normal liquid level is, however, lower than the urinal bowl 8 so that no liquid is retained in the urinal bowl. The liquid retained in the siphon trap \14 is of course discharged therefrom through the discharge pipes 15 and 12 by a siphon action in the operation of flushing the urinal bowl 8.

Means for separately flushing the urinal bowl 8 without flushing the main bowl 7 is provided and this means includes a second outlet pipe 16 extending through the bottom of the flush tank 4 and upwardly therewithin so that its upper extremity is higher than the seat 5 of the discharge pipe 3 and somewhat below the normal liquid level represented by the dotted line 17 normally maintained within the flush tank 4.

The upper extremity of the discharge pipe 16 is pro vided with a valve seat similar to the valve seat 5 for seating engagement with a conventional rubber valve member 18 which may be actuated in the usual manner by means of a lever 19, which is connected through linkage generally indicated by the numeral 20 with the valve member 18 in a manner such that actuation of the lever 19 will serve to lift the valve member 18 from its seat to permit discharge of liquid from the flush tank 4 through the discharge pipe 16 until the liquid level is lowered to the level of the upper extremity of the discharge pipe 16, which latter level is represented by the dotted line 21 at which time the floating connection of the valve member 18 with its linkage 20 permits the valve member 18 to re-seat itself upon the seat at the upper extremity of the discharge pipe 16.

The valve member 18 and its actuating means is thus similar in design and operation to the corresponding conventional means for actuating the valve member 6 which similarly comprises an operating lever 22 located on the exterior of the flush tank 4 and connected through operating linkages generally designated 23 with the valve member 6.

Water is supplied to the flush tank 4 by means of the supply pipe 24 extending into the flush tank 4 and controlled by a conventional ball cock 25 which is actuated by a lever 26 having at its outer end a ball float 27 which floats in the liquid in the flush tank 4, rises with the rising liquid level in the tank 4 and shuts off the flow of water from the supply pipe into the flush tank 4 when the liquid level therein reaches the normal level represented by the numeral 17.

The discharge pipe 16 communicates with a pipe or conduit 28 which may pass around a portion of the upper part of the bowl section B so as to discharge into the urinal bowl 8 for flushing the same. For this purpose, the pipe 28 may be disposed within a portion of the channel section 1 or at some other location within the confines of the bowl section B. The urinal bowl 8 may have its upper rim provided with a channel formation 29 similar to the channel formation 1 and extending around the upper periphery of the urinal bowl 8 so as to provide a conduit for liquid around the upper portion of the bowl, the channel formation 29 being provided with a plurality of apertures 29a adjacent the interior surface of the urinal bowl 8 so as to permit liquid to be conducted around the conduit 2% provided by the channel formation 29 and also flow out through the apertures 29aand flush down the sides of the bowl in a manner similar to that described with reference to the main bowl 7. As will be understood, the conduit 28 discharges into the conduit 2% provided by the channel formation 29.

In operation, whenever the urinal bowl 8 has been used for urination, this bowl may be flushed by actuation of the lever 19 to raise the valve member 18 from its seat and permit discharge of liquid from the flush tank through the discharge pipe 16 until the liquid level in the tank 4 lowers from the normal level 17 to the level 21 at which time the valve member 18 will re-seat itself on its seat at the upper extremity of the discharge pipe 16 and the ball float 27 having lowered to the lower level of the water in the flush tank represented by the numeral 21 serves to open the ball cock 25 for inflow of water from the supply line 24 into the flush tank 4 to again raise the level of liquid therein to the normal level represented by the line 17.

Thus it will be apparent that when urinal bowl 8 is separately flushed in the manner above described, there is utilized for this purpose only a relatively small quantity of water represented by the difference in liquid level between the lines 17 and 21.

It will be apparent of course that when it is desired to flush the main bowl 7, this will be accomplished by actuation of the lever 22 in the usual manner to displace the valve 6 from its seat until the liquid in the flush tank is almost completely discharged through the discharge pipe 3 whereafter the valve member 6 will re-seat itself on its seat and the ball cock 25 will automatically operate to restore the liquid level in the tank 4 to the normal level 17. A small pipe or conduit 30 is provided for communication between the discharge pipe 3 and the discharge pipe 16 so that when the lever 22 is actuated to flush the main bowl 7 a small portion of the liquid in 4 the tank 4 is diverted through the pipe 30 to the conduit 28 for simultaneously flushing the urinal bowl 8, the conduit 30 being of much smaller diameter than the discharge pipe 3 so as to divert only a relatively small quantity of water for the flushing of the urinal bowl.

It will be apparent from the foregoing that my invention in providing a separate urinal bowl within the main bowl of a conventional toilet and in providing means for flushing the urinal bowl by the utilization of a small quantity of water from the conventional flush tank, serves to greatly economize on the use of water for purposes of flushing the toilet after urination and provides for quietness of operation among other advantages.
