Abstract

ABSTRACT

A water tank located above a conventional toilet tank so as to flow water downward into the toilet tank; the water tank including a drain pipe downward into the toilet tank a hinged cover on top and a mechanism to flow water outward therefrom into the toilet tank.

Description

BACXGROUMD OF THE INVENTION

This invention relates generally to toilet tank flushing systems.
It is well known that conservation of -the natural resources such as water is urgently needed these days in view of the rising costs of fresh water being pumped to a house.

SU~ARY OF THE INVENTION

Accordingly it is a principal object of the present invention to provide a water storage tank into which water is placed that has already been used such as in a washing machine or bathtub so that such used water may be further re-used for flushing a toilet tank.
Another object is to provide a water conservation tank which is installed on top of a conventional toilet tank and wherein the water automatically feeds from the water conservation tank and into the conventional toilet tank whenever the water level inside the toilet tank becomes lowered by the flushing action of the toilet.
Further objects of the invention will appear as the description proceeds.
To the accomplishment of the above and related objects, this invention may be embodied in the Eorm illustrated in the accompanying drawings, attention being called to the fact, however, that the drawings are illustrative only and that

-2-chanyes may be made in the specific construc-tion illustrated and described within the scope of the appended claims.

RIEF DE CRIP'rION OF THE RAWING FIGURES

The figures on -the drawings are briefly described as follows:
Figure 1 is a front perspective view of the invention installed above a toilet tank.
Figure 2 is a cross sectional view taken on line 2~2 of figure 1.
Figure 3 is a cross sectional view taken on line 3-3 of figure 2.

ETAILED DESCF<IPT ON~S OF_ lt'~ ~ '~1 ~O EUBODIMENTS

Referring now to the drawing ln greater detail, the reference numeral 10 represents a water feeder conservation tank, according to the present invention, wherein there is a tank member 11 placed upon a stand 12 which res-ts upon a washroom f]oor 13 and the tank member being located over toilet tank 14 or a toilet 15.
The stand accordingly includes a hori20ntal frame 16 against which the edge of the tank bottom rests and four downward legs 17 therefrom.

The tank member includes a bottom wall 18 and upward side walls 19 from the edges thereof. A drain pipe 20 extends downwardly inside the toilet tank 14.
Accordingly, the toilet tank 14 may either have its conventional lid completely rernoved therefrom or else it may be replaced with a special lid completely removed therefrom or else it may be replaced with a special lid 21 having a central hole 22 through which the drain pipe extends.
A cover 23 pivoted on hinges selectively closes the opening at an upper end of the tank member 11. A flexible wlre or chain 25 is connected at its one end to a hook 26 on an underside of the cover 23 and its lower end is connected to one end one end of a rocker arm 27 pivoted at its center on a ; bracket 28 installed upon an upper side of the tank bottom wall 18. An opposite end of the arm 27 has a hollow Eloat ball 29 secured fixedly thereto and which seats upon the upper end of the drain pipe so as to selectively close the drain pipe opening 30 and prevent water 31 placed into the tank member from draining downward into the toilet tank.
The float ball, being hollow, has a natural tendency to float upwardly off the drain pipe seat. A tension coil spring 32 is installed along the chain so that when the cover 23 is pivoted upwardly into ~n open position, such as when pouring water into the tank member 11, the chain and spring pulling upwardly against one end of the arm 27 cause the float ball to remain seated on the drain pipe so as to prevent water from ~lowing out of the tank member. When the cover is downwardly closed the chain and spring relax so as to allow the float 35i~

ball to float up off drain pipe seat. rrhus water flow out oE
the tank member whene~er the toilet bowl is flushed.
A gasket 33 around an upper edge of the tank member insures an air-tight seal when the cover is closed so as to form a low air pressure area 36 inside the -tank member, over the water 31 when some of the water is outwardly drained from the tank member.
In order that the present invention is used, as intended, the valve 37 on a fresh water supply line 38 may be shut off, so that turning the handle 35 serves only to flush the water from the toilet tank into the toilet bowl and not to refill the toilet tank with a fresh water supply.
When the water 34 is thus drained out of the toilet tank, the water level 35 thus droops lower than a lower end of the drain pipe 20, thus automatically causing the water 31 from the tank member 11 to drain into the toilet tank until the water level is again restored at a lower end if the drain pipe.
Recycling water form a bathtub washing machine or the like is placed into the tank member 11 by simply lifting the cover 23 and pouring the water therein.
While certain novel features of this invention have been shown and described and are pointed out in the annexed claims, it will be understood that various omissions, subs-titutions and changes in the forms and details o~ the clevice illustrated and in its operation can be made by those skilled in the art with out departing from the spirit of the invention.

Claims (2)

What is claimed is:

1. A water feeder conservation tank, comprising, in combination, a tank member on a table and installed over a conventional toilet tank of a toilet, a drain pipe through a bottom wall of said tank member and a float ball mechanism on a top of said drain pipe.

2. The combination as set forth in claim 1, wherein said float ball mechanism is controlled by a chain attached to said hinged cover and a spring on said chain whereby said float ball is urged against said drain pipe by said spring when said cover is open thereby preventing any water from entering said drain pipe.
