Improvements in Water Waste Preventor and Flushing Cisterns for
Water Closets, Urinals, Drains, and the like.
I, EDWARD TRAIES trading as Traies & Son, of 6 Elgin Crescent, Notting Hill
in the County of London Sanitary Engineers and Universal Contractors do hereby
declare the nature of this invention to be as follows:-
:-
My invention has relation to water waste preventor and flushing cisterns for use
in flushing water closets latrines, urinals drains and for other flushing purposes and
its object is to ensure the most effective and certain action under equal conditions
with a minimum of mechanical or wearing parts liable to derangement.
In carrying out my invention I use an ordinary cistern; and syphon either in the
form of a bent pipe or domed pipe, the crown of which syphon when the cistern is
charged with water is submerged sufficient for my purpose and the outlet end of the
syphon is carried into a receiver placed below the cistern which in use retains
sufficient water to seal the lower end of the syphon against the compression of air
which takes place in the syphon by the filling of the cistern with water, a
sufficient depth of water being maintained in the receiver by the raised outgo of the
flushing pipe.
From the crown of the syphon I take an air pipe to any convenient position and
fit the same with a spring or other valve and this enables me to actuate the waste
preventor by a push on the spring valve, which has the effect of releasing the
compressed air in the syphon and allowing the water in the cistern to gravitate to
the flushing pipe in the receiver thereby setting up a syphonic action, completely
emptying the cistern.
I utilize the compressed air in the syphon to effectually prevent the waste
so common in waste preventing cisterns. Firstly in preventing the escape of water
from the cistern and secondly, as my motive power in starting the flush.
I am enabled by making many of the working parts fixtures, to minimise both
noise in action and the wearing of parts and to entirely dispense with a chain or
other pull for starting the flush which is a distinct advantage and makes it possible
for the waste preventor to be fixed in any room or position other than that in which
the water closet is placed, without a complicated arrangement of cranks, wires,
chains or levers. The water waste preventor can also be used in connection with
valve closets.
I am able to adopt the same principle in the construction of automatic flushing
tanks, the syphon being either an ordinary bent pipe, or a vertical pipe with a fixed
domed cover fitted at the crown with a valve which is actuated when the cistern is
filled to the required level by means of a float and lever.
The cistern when used as waste preventor would be filled by means of a silent
ball valve which would cut off the water when at its proper level but when used as
an automatic flushing tank would be filled by means of an ordinary stop valve
adjusted to the required period of discharge.

Improvements in Water Waste Preventor and Flushing Cisterns for
Water Closets, Urinals, Drains, and the like.
I, EDWARD TRAIES, of 6 Elgin Crescent Notting Hill, in the County of
London, 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 :-
My invention has relation to water waste preventors and flushing cisterns for use
in flushing water closets, latrines, urinals, drains and for other flushing purposes
and its object is to ensure the most effective and certain action under equal
conditious.
My invention is illustrated in the accompanying drawing marked Fig. 1 and in
the drawing marked Fig. 2 accompanying my Provisional Specification.
I will first describe my improved water waste preventor and flushing cistern
represented at Fig. 1.
In carrying my invention into effect I use an ordinary cistern A and syphon B ;
either in the form of a bent pipe or domed pipe, the crown of which syphon when
the cistern is charged with water is submerged sufficient for my purpose and the
outlet end of the syphon is carried into a receiver C placed below the cistern A
which in use retains sufficient water to seal the lower end of the syphon B against
the compression of air which takes place in the syphon by the filling of the cisteru
with water, a sufficient depth of water being maintained in the receiver C by the
raised outgo D' of the flushing pipe.
In the crown of the syphon I place an automatic air valve H worked by links
and levers I. I actuated by the ball lever G¹ of the valve G and take an air pipe E
from the same to any convenient position; and fit the same with a spring or other
valve F and this latter enables me to actuate the waste preventor by a push on the
spring valve F which has the effect when the cistern A is filled of releasing
the compressed air in the syphon B and allowing the water in the cistern A
to gravitate to the flushing pipe D in the receiver C, thereby setting up a syphonic
action which completely empties the cistern A.
At the same time by means of the automatic air valve H at the top of the
syphon B I render it impossible for any water to be discharged until the cistern is
again ready for use as the air is imprisoned in the syphon B until by the filling of
the cistern the air valve H is raised by the ball valve lever G', after which the
cistern can be discharged by pushing in the spring valve F and thus liberating the
compressed air in the syphon.
I utilize the compressed air in the syphon B to effectually prevent the waste so
common in waste preventing cisterns. Firstly in preventing the escape of water
from the cistern and secondly as my motive power in starting the flush.
I am enabled by making many of the working parts fixtures to minimise both
noise in action and the wearing of parts and to entirely dispense with a chain or
other pull for starting the flush which is a distinct advantage and makes it possible
for the waste preventor to be fixed in any room or position other than that in which
the water closet or other convenience is placed, without a complicated arrangement
of cranks, wires, chains or levers.

page_text: would here remark that in experimenting with a water waste preventor
constructed as shown and described in my Provisional Specification with respect to
Fig. 1. I found that if the air valve F were operated when the cistern was only
partially filled there would not be sufficient air imprisoned in the pipe E and
sypbon B to prevent the water rising in the syphon B above the bend thereof
whereby the water would flow from the cistern A as fast as it would enter the same
thereby rendering the apparatus useless as a water waste preventor, but by the
addition of the automatic air valve H, which acts similarly to the valve E, Fig. 2,
I obviate this difficulty and by the use of the additional air pipe K connected to
the air pipe E and open at its lower end and descending into the cistern A I obtain
an additional quantity of compressed air which assists the operations of the water
waste preventor and flushing cisteru.
I also adopt the same principle in the construction of automatic flushing tanks.
This part of my invention is represented at Fig. 2 in which A. is the cistern
provided with a syphon which may consist of a fixed vertical pipe B with a fixed
domed cover as shown or of an ordinary bent pipe. The lower end of the syphon
descends into a receiver C below the cistern A and water is retained in such
receiver by the raised outgo of the flushing pipe D in a similar manner to that
shown at Fig. 1.
In the crown of the syphon is fitted a valve E similar to the valve H Fig. 1
which is actuated, when the cistern A is filled to the required level, by means of a
float and lever F to liberate the air imprisoned in the syphon and thus start the
flush. The tank is filled by means of an ordinary stop or other valve G adjusted
to the required period of discharge.
Having now particularly described and ascertained the nature of my said inven-
tion and in what manner the same is to be performed I declare that what I
claim is :-
1. The peculiar arrangements and combinations of apparatus constituting my
improved water waste preventors and flushing cisterns, substantially as herein
shown and described and for the purpose stated.
2. In water waste preventors and Hushing cisterns the combination of a flushing
cistern A provided with means for automatically filling the same to a given level
and with an overflow pipe L, a syphon B, a receiver C below the cistern A into
which enters the longer leg of the syphon, a flushing pipe D, having a raised
outgo D' within the receiver C, an air pipe E connected with the crown of the
syphon, a spring or other air valve F to release the imprisoned air and thereby set
the syphon in action, and an automatic air valve H within the union joining the air
pipe E with the crown of the syphon substantially as herein shown and described
and for the purpose stated.
3. In a water waste preventor and flushing cistern the combination with a syphon
of an air vent communicating with the crown thereof a valve in connection with
such air vent and means for operating the valve to release the air from the syphon
when it is desired to discharge the water from the cistern substantially as herein
shown and described.
4. In a water waste preventor and flushing cistern the combination therewith of
a syphon, an air vent or pipe connected with the crown of the syphon, au air
releasing valve controlling such air vent or pipe and capable of being operated to
release the air from the syphon when it is desired to discharge the water from the
cistern and an automatically operated air valve to prevent the passage of air from
the crown of the syphon until the cistern is properly filled substantially as herein
shown and described.
5. In an automatic flushing tank provided with means for filling the same within
a given time, the combination therewith of a syphon, a receiver below the cistern
into which enters the longer leg of the syphon, a flushing pipe having a raised
outgo within the receiver, an air vent connected with the crown of the syphon, a.
