I THOMAS GOODE MESSENGER of Park Road Loughborough, Leicestershire,
Valve Manufacturer do hereby declare the nature of my invention for IMPROVE-
MENTS IN APPARATUS FOR REGULATING THE SUPPLY OF WATER TO
CLOSETS, & OTHER SITUATIONS WHERE INTERMITTENT SUPPLIES ARE REQUIRED to.
be as follows:-
:-
WATER
My Invention relates to apparatus used for the purpose of preventing waste by
stopping the flow of water (so frequently occurring through partial syphonic action)
in Flushing Cisterns and others made on the syphonic principle and which
are used especially for Water Closets and other Sanitary purposes.-Though
capable of being used in combination with the apparatus set forth in my patent
Number 7601, wherein there is provided a valve or its equivalent for admitting
air into the syphon when the flow of water is required to cease, my Invention is
especially intended to be used in Syphon Cisterns which are not provided with
such valve or its equivalent. Its object is to keep the Syphon full of air at all
times except when in use so that partial syphonic action or continuous leakage
from any cause whatsoever cannot take place.
To accomplish the above object I provide a valve, tap, pipe or their equivalent
and connect it to the discharge pipe of cistern in such a way that, when desired,
it will admit air into the syphon at any point in the long leg of same but
preferably below the level of the bottom of the short leg.

I, THOMAS GOODE MESSENGER of Park Road Loughborough in the County of
Leicester, Valve Manufacturer do hereby declare the nature of my invention for
IMPROVEMENTS IN APPARATUS FOR REGULATING THE SUPPLY OF WATER TO
WATER CLOSETS, LAVATORIES AND OTHER SITUATIONS WHERE INTERMITTENT
SUPPLIES ARE REQUIRED AND FOR PREVENTING WASTE THEREFROM, and in what
manner the same is to be performed, to be particularly described and ascertained
in and by the following.statement:-
My invention relates to Apparatus used for the purpose of preventing waste of
water in Flushing and other Cisterns made on the Syphonic principle and which
are used especially for Water Closets and other Sanitary purposes. To carry out
my invention I insert-an-Air-duct, A-(sec drawing) Valve, Tap, Pipe, Tube, or
their equivalent in the Syphon-in such a way that there may be free communication
through the said Air-duct A, Valve, Tap, Pipe Tube or their equivalent between
the atmosphere on the one hand and the interior C of Syphon on the other, and
that the air entering the said Air-duct, Valve, Tap, Pipe Tube or their equivalent
may be conducted thereby into the interior C of the long leg of Syphon or Flush-
pipe to a point B lower than the bottom D of the short leg of same.-I prefer to
insert the said Air-duct, Valve, Tap, Pipo Tube or their equivalent at the top of
Syphon and to carry a pipe E attached thereto down the interior of the long leg
to a point B lower than the bottom D of the short leg of syphon, but the Air-duct,
Valve, Tap, Pipe Tube or their equivalent may be inserted anywhere without
affecting the principle of this invention, and carried to the point named.
The Air-duct, Valve, Tap, Pipe, Tube or their equivalent may be arranged, if
desired, only to admit air into the Syphon at certain times, or only to shut off air
therefrom at certain times, or it may be arranged (as I prefer) to afford a means
of free communication at all times between the atmosphere and the interior of
Syphon.
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
The employment of an Air-duct, Valve, Tap, Pipe Tube or their equivalent by
which Air is introduced into the long leg of Syphon or Flush Pipe at a point lower
than the bottom of the short leg of same so that the Syphon may always, except
when in use, be kept full of air and a partial vacuum prevented from being formed
substantially as set forth and described.
