Improved Apparatus for Preventing Waste of Water.
Year: 1898

page_text: I, SORABJI MUNCHERJI RUTNAGUR, of 27, Medows Street, Fort, Bombay, India,
Journalist, do hereby declare the nature of this invention to be as follows;-
The object of my said invention is to construct a water cock so as to prevent
the waste of water.
According to this invention I use a water cock with branch pipes in combina-
tion with two reservoirs or cisterns each of them large enough to hold any pre
determined quantity of water. The water cock is a multiple way cock. In one
position of the cock one of the passages in the plug forms a continuous passage
from the main water supply pipe to say the left hand reservoir or cistern while
another passage in the plug connects the right hand reservoir with the delivery
pipe. When the right hand reservoir has discharged its water and more water
is required the plug of the water cock is turned so as to bring the right hand
reservoir into communication with the delivery pipe. The quantity of water
delivered at each discharge will be limited by the capacity of each cistern thus
preventing any waste of water should the tap be left open as is frequently the
case since a further supply cannot be drawn unless the plug of the water cock
is turned so as to reverse the communications.
While one cistern is being emptied the other is filling.
Although for convenience of description I mention right and left hand reser-
voirs it is to be understood that this particular disposition is not essential. The
reservoirs may be arranged in any convenient position with regard to each other
and to the water cock. In some cases a single reservoir divided into compart-
ments may be used.
The cock may be turned by hand or automatically by water or other pressure
controlled by coin freed mechanism.
Improved Apparatus for Preventing Waste of Water.
I, SORABJI MUNCHERJI RUTNAGUR, of 27, Medows Street, Fort, Bombay, India,
Journalist, do hereby declare the nature of this invention and in what manner
the same is to be performed to be particularly described and ascertained in and
by the following statement:-
The object of this invention is to provide an apparatus of a cheap and simple
construction which will prevent the waste of pipe water.

page_text: According to my said invention I combine a multiple way cock having branch
pipes connecting two independent reservoirs or cisterns with the supply or main
pipe so as to isolate the supply or water to be immediately delivered from the
main supply pipe. Each of the cisterns or reservoirs is large enough to hold
any predetermined quantity of water.
The cock is so constructed that while in
one position one of the passages in the plug connects the supply pipe to one of
the reservoirs or cisterns another passage in the plug connects the other cistern
or reservoir with the delivery or discharge pipe. Thus by turning the plug in
the cack in one direction or the other one reservoir or cistern will be emptying
while the other is filling. The quantity of water delivered at each discharge
will be however limited by the capacity of each cistern or reservoir thus prevent-
ing any waste of water should the tap be left open as is frequently the case
since a further supply cannot be drawn unless the plug is turned so as to reverse
the communications.
In the accompanying drawings in Figure 1 a represents the supply pipe and rr
two reservoirs or casterns (of any kind) each of them large enough to hold say
a bucketful of water. t represents a four way cock with a plug having two inde-
pendent passages. One of the four openings of the cock is connected with the
inain or supply pipe a, the second communicates with r by means of the pipe b,
the third communicates with r through the pipe c while the fourth d is the
delivery end from which buckets or other vessels may be filled. Figures 2 and 3
show sections of the plug p, and the cock t. In Figure 2 the plug p is shown
in the position allowing the water from the main or supply pipe a to enter the
reservoir r. When water is required for use the plug 2 is turned so as to bring
its passages in the positions shown in Figure 3. This will let the water from r
rush out at d and allow the reservoir r¹ to fill through the pipe a. The quantity
of water delivered from will be however limited to a bucketful or whatever
may be the contents of the reservoir r. Thus any waste of water will be pre-
vented should the tap be left open as is frequently the case, since a further supply
cannot be drawn unless the plug p is turned to its former position as in Figure 2
in which case the supply will be drawn from the reservoir while r is filling
Should a smaller quantity of water than that contained in any one of the reser-
voirs be required the plug may be closed in mid position as shown in Figure 4.
Although for convenience of description I have shown right and left hand
reservoirs it is to be understood that this particular disposition is not essential.
The reservoirs or cisterns may be arranged in any other convenient position
with regard to each other and to the water cock. In some cases a single reservoir
divided into compartments may be used.
Having now particularly described and ascertained the nature of my said
invention and in what manner the same is to be performed I declare that what
I claim is
1. An apparatus for isolating a predetermined quantity of water from the main
supply pipe before it is drawn for use so as to prevent waste substantially as
described and shown.
2. A four way cock in combination with the reservoirs and the supply and
discharge pipes for the purpose of preventing waste of water substantially as
described and shown.
