We THOMAS HOLT, and JAMES HOLT both of Back Oxford Street, Liverpool in the
County of Lancaster Plumbers, do hereby declare the nature of this invention to be as
follows:-
:-
This invention has for its object a syphon flushing cistern so arranged that water
can only pass into the flush pipe when cistern is brought into, and is in action and that
all water passing into the syphon and flush pipe must enter by and at the mouth of the
Syphon only, and that when the cistern is not in action no water can possibly enter the
flush pipe.
That the cistern may be brought into action by either a gentle, or a violent move-
ment, and that when either take place the supply of the water to the cistern shall be
closed or stopped. In the case of non-syphon cisterns to stop the supply of water to
the cistern before the flushing valve is opened. And that the invention will at the
same time be cheap and serviceable.
(1) A syphon so fixed in or to a cistern suspended or hung on pivots or their
equivalent that when the cistern is not in action the top bend or its equivalent of the
syphon will be above the upper edges of the cistern sides and consequently any
leakage or supply of water into the cistern when not in action would overflow cistern
sides before it could get into the flush pipe which is attached to the discharge leg of
the syphon.
(2) A cistern hung or suspended on pivots or their equivalent so that the cistern
may be tilted such a distance as to bring the upper bend of the syphon or its
equivalent which is fixed at the falling end of the cistern below the surface of the water
in the cistern, the water will then charge the syphon which will then empty the
contents of the cistern into the flush pipe, the cistern may be kept tilted or allowed to
return to its position of rest without its discharge being affected. The cistern is so
balanced that it falls back to its position of rest when the force tilting it is withdrawn.
(3) A supply cock or valve with the usual lever and float is suspended inside the
cistern but not fixed to it, the float being placed at the rising end of the cistern.

page_text: (4) A cup or its equivalent with its open end upwards is fixed in and at the rising
end of the cistern the cup having its mouth directly under the float of the supply valve
the edges of the mouth of the cup being below the surface of the water in the cistern
when it is in its position of rest. This end of the cistern being raised when the cistern
is tilted the water in it goes to the falling end and leaves the float which would then
fall and open the supply valve but that the rising end of the cistern has carried up the
cup and its charge of water until it meets the float keeping it up and the supply valve
closed thus no water can get into the cistern while it is held down tilted when the
cistern resumes its position of rest it carries back the cup and its water which in turn
allows the float to fall and open the supply valve and re-fill the cistern for its next
time of use.
(5) In the case of non-syphon cisterns the said cup is actuated by the lever
employed to open the flushing valve in such a way that the cup and its contents
support the float before the flushing valve is opened.

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:
* F
This invention has for its object a cheap and serviceable flushing cistern, so arranged
that water can only pass into the flush pipe when cistern is brought into and is in
action, and that all water passing into the flush pipe must enter by and at the mouth
of the syphon or valve as the case may be only, and that when the cistern is not in,
action, no water can possibly enter the flush pipe.. The supply of water. to the cistern
being by our apparatus stopped before the flushing commences. It is further arranged;
that the cistern may be brought into action by either a gentle or violent movement,,
and that, when either take place, the supply of water to the cistern shall be closed,or
stopped.
The invention can be applied to syphon and to non-syphon cisterns, and depends,
essentially for its action on the pull being connected with a portion of the mechanism
that is pivoted so as to oscillate with the pull; in syphon cisterns the whole cistern is,
pivoted. In non-syphon cisterns, this is impracticable, but a lever carrying a small
tray or dash board receiving the water from the ball cock oscillates instead and cuts off.
all communication between the ball cock and the cistern before, the flushing pipe is
opened. We have given drawings of both a syphon and non syphon cistern by way of
explaining our invention more fully. Referring therefore to the drawings in which,
Figures 1 to 4 show the invention adapted to a syphon cistern, and Figures 5 and 6 to,
a non-syphon one..

page_text: Referring first to figures 1 to 4
A is a cistern suspended or hung on pivots P or their equivalent in such manner
that when the cistern is not in action the whole of the top bend of syphon B fixed there-
in will be above the upper edges of the cistern sides and consequently any leakage or
supply of water into the cistern when not in action would overflow the cistern sides
before it could get into the flush pipe.
To allow for the oscillation of the cistern, the connection of the syphon B with the
flush pipe is made by means of a flexible tube or a swivel joint, or as in the drawings,
a funnel V is fixed on the upper end of the flush pipe and into this funnel the discharge
or long leg of the syphon reaches and vibrates.
The mode of connection by a funnel is preferred on account of the severance of the
syphon from the flush pipe making impossible the continuous syphoning of any
leakage or supply into the cistern after a full charge of the cistern has once been
emptied.
This funnel is in plan preferably any other shape than circular, in order to prevent
rotation of water in the funnel.
If the funnel be made circular in plan, then a mid feather is placed in the exit
portion of the funnel.
The cistern is hung or suspended on pivots P or their equivalent so that it may be
tilted such a distance as to bring the upper bend of the syphon B or its equivalent
(which is fixed at the falling end of the cistern) below the surface of the water in the
cistern. The water will then charge the syphon and thus empty the contents of the
cistern into the flush pipe. The cistern may then be kept tilted or allowed to return
to its position of rest without its discharge being affected. It is however so balanced
that it falls back to its position of rest, when the force tilting it is withdrawn.
"
To the cistern is fixed a cover G and the sides of the cistern are carried up above.
the top surface of the cover any desired height generally about one inch, but where
the supply valve C is placed the height is more, the sides being carried up to well
enclose the supply valve so as to catch any splash that may be caused by delivery of
water from the supply valve on to cistern cover,. and prevent its going outside of the
cistern.
The supply valve C to the cistern is fixed at the falling end of the cistern, and the
float D working this valve is of course fixed at the rising end of the cistern.
In the cistern cover G, and directly under the supply valve a depression or hollow S
is formed so as to contain water, and this receiving the water from the supply valve
prevents the splash that would otherwise take place.
The water is taken off the cover into the lower part of cistern by means of a way or
port O formed in the cover and at the rising end of the cistern, and by preference as
far away from the supply valve C as possible.
To allow for the movement of the supply valve C, a space is formed in the cistern
cover to allow the float to pass and work through, and this space has a rim round it
about equal in height to the sides of the cistern above the cover so as to prevent the
water entering the lower part of cistern by this space.
At the rising end of the cistern, and in the side an overflow channel K is formed by
cutting away a portion of the side any desirable depth from the top edge of the side,
and continuing this cutting in any approved form to over the mouth of a fixed overflow
pipe L.
2
The cistern is tilted by means of a pull or handle R connected with the cistern by a
chain, cord, rod, or any other of the usual and well known means.
In the case of self acting water closets and urinals, the cistern is so balanced as
when at rest it lies in its tilted position, the falling end down, and is brought to
its level position by the action of the water closet or urinal apparatus when being used.
The overflow channel in the case of self acting water closets and urinals is formed in
the sides of the falling end of the cistern, and it may also be at this end in cisterns
actuated by a pull if desired.
.
The cistern is enclosed in a box or casing N to which is attached the bearers upon
which the pivots work.

page_text: The supply valve C which is fixed over the cistern is also fixed to this casing, and as
is also the funnel V in which the long leg of the syphon B vibrates.
A cup or its equivalent E is fixed with its open end upwards in and at the rising
end of cisterns, and directly under the space formed in the cistern cover to allow the
supply valve float D to pass, and in this cup the float works.
The upper edges of this cup are so arranged as to be under water when the cistern
contains its desired quantity and by preference only just under the surface of this
water.
When the cistern is tilted the cup being carried up takes along with it, its contents,
and also the float, a portion of the contents of the cup is discharged into the cistern but
sufficient remains to hold up the float and keep the supply valve closed whilst the
cistern remains tilted.
The mode of action is therefore as follows :—
Assuming the cistern is filled with water just over the top edge of the cup E, then
on pulling down the falling end of the cistern A. A which is hung on pivots P, the
syphon B is brought below the surface of the water contained in the cistern A, this
water flowing into the syphon B charges it and causes the required discharge of the
cistern A into the funnel V whether the cistern be held down tilted or allowed to
resume its level position.
At the same time as the falling end is pulled down the rising end is carried up, and
with it the cup E and its contents, part of which is discharged into the cistern, and the
remaining portion holds up the float D which by means of the lever F keeps the supply
valve C closed.
When the cistern resumes it level position which its does when the pull is released, in
consequence of its being so balanced, the cup E and its water leaves the float D which
falling opens the supply valve C by means of the lever F, and water being then
delivered onto the cistern cover G runs along it to the opening 0 and through it
into the lower part of cistern A, fills this cistern up to the top edges of the cup E
overflows into and fills the cup lifting the float D, which shuts the supply valve C,
and the cistern is now ready for another discharge or use.
If there be any leakage of the supply valve C the cistern will fill until the water
reaches the overflow bridge H over which it will run into the channel K and thence
away by the pipe L.
Should the cistern be tilted when the supply valve is leaking, the leakage would not
run into the lower part of the cistern by the opening O or to the overflow channel, but
in the opposite direction, and if the cistern be held down tilted a sufficient time, the
water will run over the edge M of the cistern and thus give notice of the waste taking
place as well as making inconvenient the use of the cistern until the necessary repair
is effected, and waste by leakage prevented. The cistern rests on the stop X when in
its level position.
Referring now to Figures 5 and 6-In these E is the cup in which the float D
works. It is suspended to one end of the lever B employed to raise and open the
flushing valve W.
The cup E is attached by means of links J, J, to the same end of lever B as the
flushing valve W, the lever and cup are arranged to move some distance before the
flushing valve is moved and this distance is such that the water in the cup will have
lifted the float and closed the supply valve before the flushing valve is lifted.
The lever B is made in the form of a gutter or trough having a bottom, two raised
sides and one raised end, the other end open, and it is to this open end that the cup E
and the flushing valve W are attached.
Over this trough shaped lever B and at the opposite end to which the cup is
attached is fixed the supply valve which delivers the water into a hollow or
depression S in the bottom of the trough, along which trough the water travels to its
open end and falls into the cistern.
.
Partly surrounding the supply valve the sides of the trough are carried well up to
form a guard against any splash caused by delivery of the water from the supply
valve.

page_text: It will be seen that the parts of this cistern have in nearly every instance their
representatives in the cistern already described, the exception being that a valve is
used instead of a syphon, and the top only pivoted instead of the whole.
The mode of action is as follows:
Assuming the cistern A to be filled with water, then on pulling down by means of
the pull R the lever B, B, which is pivoted at P, P, the cup E with its contents are
raised and meet and carry up the float D which shuts the supply valve C by means of
the lever F, and soon after this takes place and the downward movement of the pull
continuing the collar U on the spindle X which is attached to the cup E meets the
projection on the top of the sleeve formed in the valve W, and lifts this valve, and the
contents of the cistern A are then discharged.
cup
On releasing the pull R the lever B falls back, the valve W first closes, and then the
E with its contents leave the float D, which then falling opens by means of the
lever F, the supply valve C, the water from which falls into the trough shaped lever B,
runs to its open end which is next to the float D, falls into and fills the cistern A
reaching and lifting the float D which in turn closes the supply valve C and the cistern
is then ready for another use.
In the event of the supply valve C leaking, the leakage is taken away from the cistern
But if the lever B, B is pulled
by the overflow pipe L which is of the usual kind.
down by the pull R at the time that there is any leakage of the supply valve C then
the leakage does not pass into the cistern, but down to the end of the trough in the
lever, where the pull R is attached to the lever, the leakage will then overflow, over the
end of the trough and outside the cistern, and so render the use of the cistern
inconvenient during the time the leakage of the supply valve C is allowed to continue.
Having now particularly described and ascertained the nature of the said invention,
and in what manner the same is to be performed, we declare that what we claim is :-
1st. The combination of a tilting cistern with a syphon whose whole upper bend
stands above the top edge of the cistern, whereby when the cistern top is level, and the
cistern filled to overflowing no water can go through the syphon but may overflow the
edges of the cistern.
2nd. The combination with a tilting flushing cistern of a cover fixed in a water tight.
manner to the cistern for the purpose of preventing the water in the cistern from
flowing over its sides when tilted, and also to enable the water when the cistern is
tilted to be higher than the head of the syphon, and so charge it.
3rd. A covered flushing cistern cover, the sides of which stand some height above
the top surface of the cover, substantially as and for the purposes specified.
4th. In combination with the supply valve of a tilting flushing cistern (or flushing
cistern with tilting cover) fixed so as to deliver its water on to the cistern cover, near the
falling end, a cover formed with opening into the cistern at the rising end, whereby the
water of the supply valve is cut off from the cistern whenever the cover is in the tilted
position, and any extra leakage is conveyed over the outside edge of the cistern when
it is tilted.
5th. A cup.or small container fixed in the rising end of the cistern for the purpose
of holding water to support and carry the float working the supply valve, and so
arranged that part of its contents are thrown out of it when the cistern is tilted, but
sufficient water is retained to hold up the float and keep the cistern supply valve closed
whilst the cistern is so tilted, but not when the cistern resumes its level position, and
when the cistern is filled with water, the water overflows into the cup and fills it, raising
the float and thereby closing the supply valve.
6th. In combination with non-syphon cisterns a cup to contain water, and so
suspended to the lever opening the flush valve that the cup with its contents will when
the lever is being moved to open the flush valve have reached the float working
the supply valve and hold the supply valve closed before the flush valve is opened.

page_text: 7th. In combination with a non syphon cistern the lever for opening the flush valves
formed with a gutter or trough to receive the water from the cistern supply valve
before it enters the cistern, and so arranged that the water is delivered into the cistern
from off that end of the lever to which the flush valve is attached, whereby when the
flush valve end of the lever is up and the other end being down, any leakage from the
supply valve will flow along the trough or gutter, and over the end of the trough, and
outside the cistern, the end of the trough shaped lever being carried beyond the outside
of cistern.
