We JOSEPH JAMES DAY and THOMAS ISAAC DAY both of No 76 Leighton Road
Kentish Town in the County of Middlesex Sanitary Engineers, do hereby declare
the nature of our Invention for AN IMPROVED WASTE PREVENTING VALVE AND
SYPHON COMBINED, to be as follows:-
Our improvements relate:
Firstly. To a metal ring cast to a suitable shape to receive a flexible ring or
washer which when spun in the metal ring forms a perfectly sound seating.
This valve is then attached to the bottom of a metal tube or cylinder round the
outer side which is left open at the top. There is also a second tube or cylinder
closed at the top; to the bottom part of this tube or cylinder is attached the outer
side of the valve or ring previously mentioned. This combination together forming
the syphon by means of a three way fluted parallel feather or guide working on
the inner side of the first named tube or cylinder.
This combined syphon and valve which is raised by means of a lever attached
to the top of the outer tube or cylinder at each lift or pull forms a vacuum by the
action of the air and water which is again released by each flush, causing the
valve or syphon to come in contact with the metal seating which is fixed to
the bottom of the vessel or tank at once producing a complete valve and syphon
combined.

An Improved Waste Preventing Valve and Syphon Combined.
We JOSEPH JAMES DAY and THOMAS ĮSAAC DAY both of 76 Leighton Road
Kentish Town in the County of Middlesex Sanitary Engineers do hereby declare
the nature of our said invention for "AN IMPROVED WASTE PREVENTING VALVE
AND SYPHON COMBINED," and in what manner the same is to be performed to be
particularly described and ascertained in and by the following statement, to be
as follows:
Our Invention has for its object an improved waste preventing valve and syphon
combined whereby means are employed for forming perfectly sound seatings for
the valves and at the same time securing the smooth and easy working of all
its parts.
In order that our invention may be fully understood and easily carried into
practice I have appended hereunto a sheet of Drawings on which
Fig. 1. is an elevation of our invention.
Fig. 2. is a sectional elevation shewing the syphon in action.
Fig. 3. is also a sectional elevation shewing the syphon in action after the lift
suction is exhausted.
Fig. 4. is a sectional elevation of a cistern or tank shewing our improved waste
preventing valve and syphon in working position.
We construct our waste preventing valve and syphon as follows,-
A metal ring A is cast or otherwise formed of a suitable shape to receive an
india-rubber or other suitable flexible ring or washer B which when formed or fixed
in the said metal ring forms a perfectly sound seating.
This ring and washer or valve A B is then suitably attached to the bottom outer
side of a metal tube or cylinder C which is left open at the top as shewn in the
Drawings. Around this tube is another tube or cylinder D which is closed at the
top but has perforations a in its lower part, this cylinder D is also soldered or
otherwise securely fixed to the outer edge of the valve A. B. This combination
together with the outer tube or cup H which enters the water and the use of the
three way fluted parallel or tapered feather or guide E working on the inner side
of the tube or cylinder C (Fig. 2) forming the syphon. Or the feather E may be
fixed in the tube C and working or forming its guide in the seating F (Fig. 3).
This combined syphon and valve which is raised by means of a lever G attached
to the top of the tube or cup H at each lift or pull forms a vacuum by the action
of the air and water which on being released or not by each flush causes the
valve or syphon to come in contact with the metal seating F fixed to the bottom
of the tank at once producing a complete valve or syphon. Or instead of the tube or
cup H forming the suction by being inserted in the water we, in some cases, shorten
it and employ a supplementary washer K fixed in any convenient manner to the
outer casing or cup H or it may be fixed to the top of the closed tube or casing D
which would cause exactly the same suction, thus the water being at any height
the syphon will be brought into action.
We will now explain the action of our invention as applied to an ordinary water
closet flushing cistern or tank, The lever G is pulled down by the chain M which
action lifts the outer tube or cup H having the flexible washer K fixed thereto sai
食

page_text: washer being flexible adheres firmly by suction to the top of the cylinder D until
such time as the air is exhausted when it looses its hold and drops which causes
the syphon action and the casing D again falls into its normal position the ball
cock P acting in the ordinary manner again filling the cistern. There is also a
second action which should it be pulled up and let go too quick for the suction to
take its action the syphon action would then take place and flush the apparatus as
above described.
Having now particularly described and ascertained the nature of our said
invention and in what manner the same is to be performed we declare that what
we claim is
The combination of a waste preventing valve and syphon lifted bodily and
started by suction substantially as herein described and shewn on the Drawings.
