Improvements in Syphon Flushing Cisterns.
I, WILLIAM GEORGE APPLEFORD, of Sunnyside, Church Road, Moseley,
Birmingham, in the County of Warwick, Manufacturer, do hereby declare the
nature of my said invention to be as follows:-
My invention has for its object improvements in syphon flushing cisterns by
which any waste of water is prevented and the flush is more effective and certain in
action than those hitherto in use.
In carrying my invention into effect I provide the compressor or cap of the
syphon with, two, three, four or more waterways which are formed in a vertical
direction with a horizontal bend at the top around its circumference and by which
the body of water within is more sensitive to the movement of the lever inasmuch
as the backward escape of the water when under pressure is materially reduced by
my said improvements. For the more perfect working of the compressor or cap
I provide two projecting horizontal arms which slide in guides formed upon the
sides of the cistern by which the compressor or cap is provided with a straight lift
so that during its movement a water-tight joint is formed all around the receiver
except at the points where the water ways are provided. In place of the
waterways being formed around the compressor they may be formed around the
The outer
receiver or they may enter the receiver horizontally at the bottom.
casing may be fixed, in which case a disc would be provided for lifting the water
over the mouth of the discharge two vertical rods being provided and passing
through the outer casing for connection to the lever. The compressor and receiver
may be square or other shape on plan, and in the case of those of a square shape
the waterways would be formed in the angles. The waterways are always arranged
so that the direction of the water under compression is at right angles to the mouth
of the waterway while the said mouth is easy and free in the direction of the
discharge pipe. To prevent corrosion in the internal parts of the compressor,
receiver, or dome, I may line the same with any such non-corrosive material as
white metal, glass, earthenware or vulcanite.

COMPLETE SPECIFICATION.
Improvements in Syphon Flushing Cisterns.
J, WILLIAM GEORGE APPLEFORD, of Sunnyside, Church Road, Moseley,
Birmingham, in the County of Warwick, Manufacturer, do hereby declare the
nature of my said invention and in what mauner the same is to be performed to be
particularly described and ascertained in and by the following statement :-
My invention has for its object improvements in syphon flushing cisterns by
which any waste of water is prevented and the flush is more effective and
certain in action than those hitherto in use.

page_text: In carrying my invention into effect I provide the compressor or cap of the
syphon with two, three, four or more waterways which are formed in a vertical
direction with a horizontal bend at the top around its circumference and by
which the body of water within is more sensitive to the movement of the lever
inasmuch as the backward escape of the water when under pressure is materially
reduced by my said improvements. For the more perfect working of the
compressor cap I provide two projecting horizontal arros which slide in guides
formed upon the sides of the cistern by which the compressor or cap is
provided with a straight lift so that during its movement a watertight joint is
formed all round the receiver except at the points where the waterways are
provided. In place of the waterways being formed around the compressor they
may be formed around the receiver or they may enter the receiver horizontally
at the bottom. The outer casing may be fixed in which case a disc would be
provided for lifting the water over the mouth of the discharge two vertical rods
being provided and passing through the outer casing for connection to the lever.
The compressor and receiver may be square or other shape on plan and in the case
of those of a square shape the waterways would be formed in the angles. The
water ways are always arranged so that the direction of the water under
compression is at right angles to the mouth of the waterway while the said mouth
is easy and free in the direction of the discharge pipe. To prevent corrosion in the
internal parts of the compressor, receivor or dome I may line the same with any
such non-corrosive material as white metal, glass, earthenware or vulcanite.
In order that my invention may be clearly understood and more easily carried
into practise I have appended hereunto four double sized sheets of drawings upon
which I bave fully illustrated the nature of my said improvements together with
the mode of carrying the same into effect.
Figure 1, is a vertical section through one of my compressor caps B showing the
waterways A in section the flushing pipe C in elevation and lifting disc D in
section.
Figure 2, is an exterior elevation of Figure 1.
Figure 3, is a similar vertical section to Figure 1 but showing its application to a
cistern having a well.
Figure 4, is an elevation of Figure 3.
Figure 5, is also a similar vertical section to Figure 2 but showing the cap B for
being operated without the disc D.
Figure 6, is an elevation of Figure 5.
Figure 7, is a similar vertical section to Figure 5 but showing a modification in
the construction of same.
Figure 8, is an elevation of Figure 7.
Figure 9, is a similar section to Figure 5 showing a further modification.
Figure 10, is an elevation of Figure 9.
Figure 11, is a sectional plan through same on the line 1-2.
Figure 12, is a view showing a modified form of compressor.
Figure 13, is also a view showing a modification in the compressor.
Figure 14, shows a modification in the form of syphon.
Figure 15, is a similar section to Figure 1 but showing a receiver F within the
compressor.
Figure 16, is a section also showing a modification in the receiver.
Figure 17, is a view of a receiver detached.
Figure 18, is a view of a cistern showing the guides for the compressor.
Figure 19, shows the guides formed on an outside receiver.
Figure 20, is a vertical section through Figure 19 with compressor complete.
Referring to Sheets 1 and 2 of the drawings again my compressor or cap B is
formed with one, two, three, or more waterways A which are bent over so as to
convey the water into the compressor above the compressor plate or disc B¹ by
which means the body of the water when compressed is more sensitive to the action
of the lever as there is little or no backward escape of the water. The

page_text: waterways A allow of a perfectly free forward flow of the water through the cap
or cover B in the direction of the discharge pipe C. In case of cisterns E where
the well E' is used the vertical part of the waterway A may be dispensed with as
shown at Figure 3 the water then entering direct on a line with the bottom of the
cistern and immediately above the disc Bi. In both these cases the cap is fixed and
the water is lifted by the disc D by which it is compressed between the said disc D
and the compressor plate or disc B³ of the cap B tbus causing rapid rise of the
water in the top part 3 of the cap. In some cases the compressor B is provided
with the arms b¹ Figure 5 which are actuated by the lever and work in guides e¹
formed on the side of the cistern E Figure 18 by which the compressor has a
perfectly vertical lift in the well E' of the cistern the waterways A. entering the
compressor above the compressor plate B' the water being compressed between the
bottom B¹ of the compressor B and the cistern E or well E¹ the waterways A. being
arranged for the entrance of the water above the bottom B₁ of the compressor B
in a similar manner to that before described.
The waterways A may be arranged around the circumference to any number and
may be practically continuous as shown by Figures 7 and 8 and may be carried up
distance vertically before entering the compressor B as shown by
Figures 9, 10 and 11, or the compressor may be formed with a square base
with the waterways A formed in the angles as shown by Figure 13.
some
In some cases I may provide a receiver or cup F within the compressor in which
case the waterways A may be formed in the receiver as shown at Figure 15
and also Figure 16 where the waterways are shown arranged horizontally.
Instead of the guides e¹ being formed on the cistern, an outside casing H
Figures 19 and 20 may be provided with guides h' formed upon the same. In
Figure 14 a modification of the syphon is shown the discharge pipe C' in this case
being outside the cover B. The interior of the compressor or cap is in many
cases lined with such non-corrosive material as white metal, glass, earthenware, or
vulcanite as shown by J Figure 15 while the waterways may be formed entirely of
such non-corrosive material. The receivers F may also be formed of non-corrosive
material.
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 :-
1st. The improvements in syphon flushing cisterns substantially as and for the
purpose herein set forth and shown upon the accompanying drawings.
2nd. In syphon flushing cisterns the cap dome or compressor B having one two
or more waterways A substantially as and for the purpose herein set forth and
shown.
3rd. In syphon flushing cisterns a receiver F having waterways A substantially
as and for the purpose herein set forth and shown.
4th. In syphon flushing cisterns the guides el or h¹ in combination with a cap or
compressor B having waterways A substantially as and for the purpose herein set
forth and shown.
5th. In syphon flushing cisterns an anti-corrosive lining in combination with a
cap, dome, compressor or receiver having waterways A substantially as and for
the purpose herein set forth and shown.
