PROVISIONAL SPECIFICATION.
Improvements in or relating to Syphon Cisterns and Water Waste
Preventers for Water Closets, Urinals, and similar purposes.
I, HENRY BARTLETT of 44 Baker Street Small Heath near Birmingham in the
County of Warwick Fitter and Turner, do hereby declare the nature of this
invention to be as follows:-
My invention refers to syphon flushing cisterns for the above or any similar
purposes and consists of an arrangement for flushing by means of a syphon
action.
I partition off the cistern into two compartments a larger or main compartment.
and a smaller one, at the base of the partition are inlets at intervals to afford access
for the water to the main compartment.
The stand pipe or syphon is cast in connection with two, three, or four, additional
pipes or cylindrical chambers the casting surrounding and forming the stand pipe
and cylindrical chambers being oblong on the exterior.
The stand pipe obviously is open at its top to the roof connecting the cylindrical
chambers.
The stand pipe or syphon is cast longer at its base than the pipes or cylinders on
each side thereof (which do not touch the floor of the cistern) so that it may be
fitted into the floor of the cistern in the usual manner, and thence connected to the
external supply pipe leading to the w.c. or other basin.
A plate covers the area of the main compartment of the cistern, this plate is cut
out in its centre in the same oblong manner as the casting in which is the stand
pipe &c. and large enough to allow of the plate being raised and lowered round the
centre oblong casting.
Suitable rests will be upon this plate to keep same from contact with the floor of
the cistern.
In order to lift the plate two perpendicular rods are situated one on each side
of the same in the direction of its width, these rods are secured to the plate by
screw nuts or other suitable means. Connected to the upper ends of the rods
is a lever having its bearing on the sides of the cistern and actuated by a chain
or otherwise.
The usual ball valve inlet will be provided as also an outlet.
By the raising and lowering of the plate by means of the lever connection the
water in the main compartment will be acted upon and be forced up the pipes or
cylinders on each side of the stand pipe or syphon and over the top of and down
the same causing thereby a vacuum to be formed by reason of the displaced
air so that the syphonage is started and will not cease until the whole of the water
in the two compartments is exhausted when the cistern refills in the usual way
ready for the next flushing.

Improvements in or relating to Syphon Cisterns and Water Waste
Preventers for Water Closets, Urinals, and similar purposes.
IHENRY BARTLETT of 44 Baker Street Small Heath near Birmingham in the
County of Warwick Fitter and Turner, 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 relates to syphon flushing cisterns and water waste preventers for
the above or any similar purpose and consists of an arrangement for flushing by
means of a syphou action and operating in manner as hereinafter described.
I will proceed to describe my invention with the aid of the drawings accompanying
this Specification and which form a part of the same.
Figure 1. is a sectional elevation of a cistern shewing my improved arrangement
as applied thereto.
Figure 2. is a sectional view of my arrangement of stand pipe and cylinders.
Figure 3. is a plan of the cistern and all parts complete.
Figure 4. a plan in horizontal part section shewing the water ways in partition
wall and stand pipe and side cylinders.
Figure 5. side view detail of plate and side pieces or brackets to raise aud
lower same.
Figure 6. end view and Figure 7. detail view of plate shewing cut out centre.
The same letters of reference indicate similar parts in the several figures.
According to my invention 1 partition off the cistern into two compartments a
larger or main compartment A and a smaller one B. At the base of the
partition C, are inlets forming water ways D at intervals to afford access for the
water from one compartment to another. The stand pipe or syphon E is cast
longer at its base than the pipes or cylinders E¹ on either side thereof to allow of
its being fitted into the floor of the cistern in the usual manner and thence con-
nected to the external supply or delivery pipe leading to the w.C. pan or urinal
basin, the stand pipe or syphon E is obviously open at its top to the roof or dome
connecting and forming the side pipes or cylindrical chambers E¹ these do not
touch the floor of the cistern but are open to same E" to allow the water supply
entering therein.
It should be mentioned that the stand pipe and side cylinders are fixtures to
the cistern the cylinders being connected as at E" to the stand pipe at its junction
with the floor of the cistern.
A plate F covers the area of the larger compartment A of the cistern, this plate
is cut out in its centre F1 in the same manner as the casting G (preferably oblong)
which forms the side pipes or cylindrical chambers E' and the stand pipe E,
the cut out centre is large enough to allow of the plate F being raised and lowered
around the oblong casting G, by means of the lever H, and chain or other
connection H', which lever obtains its bearing as usual on the sides of the cistern
and hooks under snugs I, upon the side pieces or brackets J on the plate F.
Fare rests on the bottom of the plate to keep it clear of the floor of the cistern.
The usual ball valve and float K K'are provided the rise and fall of which regulates
and shuts off the supply of water from the main service to the cistern. An overflow
pipe L is also used to take away superfluous water.
It is obvious that when the cistern is charging the water will also rise up within
the cylindrical chambers E' flowing through the water ways E" and will remain
at the same level as the water line of the cistern until disturbed by the pulling of
the chain.
I have not shewn a cover or top as the usual method may be adopted.

page_text: OPERATION.
On giving a momentary pull to the chain H' the arm of the lever H is depressed
upon its centre thus raising the plate F, the raising and subsequent lowering of
this plate causes the volume of water contained in the cistern to commence flowing
beneath the cylindrical chambers E' whence it is forced up same, the rising and
rush of the water towards the top of the stand or syphon pipe E forcing away the
air confined in the interior or crown of the roof or dome and also in the stand pipe
thus creating a vacuum and thereby causing the syphonic action to commence by
reason of the sudden displacement of air by the inrush of water and so starting the
initial flushing the water continuing to flow from the cistern through the channels.
provided for the purpose until the contents of the cistern are exhausted, the cistern
then refills ready for the next flushing.
By this action the water in the cistern discharges very rapidly as it rushes from.
the cistern up the cylindrical chambers E¹ over the top of and down the stand
pipe and delivery pipe, thus effectually flushing and cleansing the w.c. pan or
urinal basin.
I wish it to be understood that I not limit myself to the more precise details in
the manner of constructing the several parts herein as I may vary the same without
departing from the general principle of this my invention.
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,
Firstly. The improvements in syphon flushing cisterns and water waste pre-
venters as herein more fully described and illustrated and the special character and
arrangement of the several parts relating to such improvements, viz. the partitioned
compartments A. and B the cylindrical chambers E in connection with the stand
pipe E and their particular formation all acting in connection with each other and
with other working parts of the cistern for the purpose substantially as herein
set forth.
Secondly. I claim in a syphon flushing cistern and water waste preventer the
general arrangement and construction of the several parts or any mere equivalents
of same substantially as herein before described in the Specification and illustrated
in the accompanying drawings for the purpose as set forth.
