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.
