Improvements in Apparatus for Controlling the Supply of Flushing
Liquid to Water-closets and for other like Uses.
I WILLIAM NUNN of Woodlands, Broad Green, Croydon, in the County of Surrey,
Gentleman, do hereby declare the nature of this invention to be as follows:-
The object of the invention is the arrangement or combination in a more compact
and useful form of the parts of apparatus for controlling the supply of water or
flushing liquid to water closets or for other like uses.
In my improved apparatus I arrange a vessel which may be of cylindrical or other
convenient form closed at bottom and opened above in which vessel works a piston
carrying supports and through which passes one end of a syphon tube, this piston and
the parts connected are by a lever drawn down for supply of liquid to the water
closet or other place through the syphon tube up which the water is forced by the
descent of the piston in the vessel.
The connection to the operating lever in the water closet or other place may be by
a chain or connection to a handle conveniently placed for use. The descent of the
piston lever cuts off supply of the liquid and the return of the piston and renewal of
supply of liquid is brought about by a counterweight to the lever raising the other
end and theroby the piston and at the same time operating the valve of supply, the
filling of the vessel and of the cistern connected to or containing it being controlled
by a float lever.
Or the float lever may solely effect the control of supply.
For increase of pressure on the flushing liquid in the vessel for the purpose
of forcing it to the place of use a rolling weight may be brought to bear on
the piston by its displacement by means of a lever operated by hand or an arm or
connection from the seat or part moved to get access to the place used.

Improvements in Apparatus for Controlling the Supply of Flushing
Liquid to Water-closets and for other like Uses.
I WILLIAM NUNN of Woodlands, Broad Green, Croydon, in the County of Surrey,
Gentleman 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 :-
The object of the invention is the arrangement or combination in a more compact
and useful form of the parts of apparatus for controlling the supply of water or flushing
liquid to water closets or for other like uses.

page_text: Fig. 6 shews a vertical section and Fig. 7 a horizontal section of another
modification.
Fig. 8 shows a vertical section and Fig. 9 a horizontal section of still another
modification.
Fig. 10 shows a detail and
Fig. 11 another detail to be referred to..
c is a
In Fig. 1a is the containing vessel which is alternately filled and emptied with
water. The dotted lines in the Figure indicate the level of the water contained when
full. This water is supplied by the pipe & which passes through the cover a¹ of the
chamber a. The opening of this pipe is controlled by a valve which may be of any
suitable and ordinary description operated by the lever carrying the ball ².
syphon the inner and shorter leg of which, e, passes to near the bottom of the vessel a.
In order to force the water therein above the level of the water in the chamber a
and over the bend e' of the said syphon, the user pulls the cord d' which is connected
to the end of the arm & centred at and carrying a counterweight connected to
its und d. At d' this arm & is connected to a rod e which is again connected at e¹ to
the piston or water displacing part. This part fis centred at 1 and as soon as by
the pull on the cord this part has been pulled down to the position indicated by the
dotted lines, sufficient water will have been forced up the tube c³ to set up a syphonic
action and the vessel a will be rapidly emptied of the water down to the level of the
lip of the shorter syphon leg c¹. g is an overflow pipe. The water thus drawn
over and down the leg c is carried to the pan of the closet or other place to be
flushed.
In Fig. 3 is indicated a modification in the method of operating the part f. In
this arrangement the cord is attached to a vertical rod d which is attached to the
lever d, centred at d³, counterweighted at 5, linked by the link e to the part so that
when the end is forced down the part is forced down too to the position indicated
by the dotted lines. In this arrangement is also added a device for securing an after
flush. For this purpose the leg c of the flushing syphon is carried into a closed
chamber down to a certain level. The exit from this chamber is by means of the
pipe i to the place to be flushed. The water entering rapidly into this chamber h
passes off by overflowing the upper end of the pipe, but leaving the chamber h full
up to that level. The quantity of water thus trapped by passing off slowly into the
pipe i by the small opening forms tho after-flush.
In Fig. 4 the cord d' draws down the rod, depressing the part f, the return of
which is effected by means of the lever d, contred at d³ and counterweighted
at d, placed below the part f, which serves when that part has arrived at its
lowest position and the cord d' released, to lift the part back to its former
position.
In Fig. 6 the cord d acts on the rod dª connected to the piston plate causing
that plate to be depressed vertically. k is a coiled spring placed below the part f
which when the rod is released causes the part to rise and resume its former
position. In place of the coiled spring a spring of other form may be employed such
as an elastic connection between the upper part of the chamber c and the rod do,
the resilience of the spring reinstating the position of the parts. Or this may be
effected by a counterweight connected to the part f
As shewn in Fig. 11 the substantially close fitting of the coned piston plate f
to the sides of the chamber a is secured by forming it from a circular flut plate, then
slitting it from centro to circumference and overlapping the edges of the slit to a
sufficient amount to introduce it into the chamber a and in rising the tendency of the
plate will be to form a cone of smaller base whilst in its descent meeting with the
pressure of the water its tendency will be to enlarge and render tighter fit.
In place of the disc frising vertically it may form a closing part of an inner
chamber or it may swing on a contre or be operated in other directions by means of
links or otherwise.
In Fig. 8 the operation of the partƒ is somewhat modified, it being centred at fl
to the casing which forms an inner chamber to the chamber a, and which may be
1

page_text: cast with the short leg c' of the syphon. The part funder the influence of the lever d
connected at d¹ to the cord d' is swung on its centre 1 and thereby forces the water
over the bend of the syphon at c³.
Fig. 10 is a detail indicating how the two legs c, e forming the syphon may be
connected to the wall of the chamber a and to each other by the flanges c³ and c
thereof respectively, and bolted by the bolts c³.
In each of these arrangements of apparatus according to my invention is a vessel
shewn as of cylindrical form but which may be of other convenient form closed at
bottom and open to the atmosphere above, in which vessel works a piston or part
acting to displace the water therein on occasion, said piston carrying supports or arms
and through the piston or piston chamber passes one end of a syphon tube, this
piston or piston and the parts connected are by a lever drawn down for supply of
liquid to the water-closet or other place through the syphon tube up which the water
is forced by the descent of the piston or displacing part in the vessel. The connection
to the operating lever in the water-closet or other place may be by a chain or con-
nection to a handle conveniently placed for use. When so required, but not otherwise,
1 so arrange a connection that the descent of the piston lever cuts off supply of the
liquid for the time being. This connection is shewn applied in Fig. 1 where a chain
or other connecting line is attached to the operating lever at 2, passes over a pulley
at .', and is connected to the ball lover at so that the lowering of the operating
lever causes the holding up the ball lever, and the release of the operating lever
permits the ball to fall for refilling. The return of the piston and renewal of supply
of liquid is brought about by a counterweight or equivalent means as by a spring
applied by the lever raising the other end and thereby the piston and at the same time
operating the valve of supply.
The filling of the vessel and of the cistern connected to or containing it being
controlled by a float lever. Or the float lever may solely effect the control of
supply.
The parts in the various Figures may when desired be made to expand as described
in connection with Figures 6, 7 and 11.
In Fig. 12 is shown by vertical section and in Fig. 13 by plan another modification
in which the part for closing in upon the water and within the casing 1. forming the
inner chamber or division of the chamber a, works on the shorter leg c of the syphon
as an axis of motion, the bands m m attached to the part clasping that axis c'. The
cord, wire, chain or line pulls the segmental part within the soginental cover
pressing the enclosed water up the leg c, starting the syphonic action which continues
until the whole of the water has been drawn off by the pipe c c', the fall of the
ball lever turning on the supply of water. is a rod or stem connected by a cord or
line passing over a pulley at d to a counterweight at w or this may be by a spring in
tension or compression.
By the herein described mode of constructing apparatus for flushing water closets
and the like I am enabled to make the apparatus so as to be substantially included
within a cylinder of very small dimensions securing great compactness cheapness and
strength, the parts being few in number and less likely to get out of order.
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:
1. The various constructions of apparatus for controlling the supply of flushing
liquid to water-closets and for other like uses indicated by Figures 1. 2. 3. 4. 5. 8
and 9, as and for the purposes substantially herein set forth.
2. The constructions of apparatus for controlling the supply of flushing liquid to
water-closets and for other like uses indicated by Figures 6, 7 and 11, and described
in connection therewith wherein an expanding coned disc f is employed to cause the
water in the vessel to be forced over the leg of the syphon and so set up the syphonic
action substantially as and for the purposes hereinbefore set forth,

page_text: 3. In apparatus for controlling the supply of flushing liquid to water closets and for
other like uses, the combination or arrangement of a cylindrical outer chamber as a, a
means of supply of flushing liquid, a part for forcing a portion of such liquid into
the syphon and a syphon tube, with means of operating the various parts sub-
stantially as described.
