PROVISIONAL SPECIFICATION.
Improvements in Syphon Flushing Cisterns and Water Waste
Preventers.
I, HENRY CRANE, Junior of 183 Moseley Street Birmingham in the County of
Warwick, File Manufacturer, do hereby declare the nature of this invention to be
as follows:-
This invention relates to a method of flushing w.c.'s, urinals, and such like where
a flush of water in a given quantity may be required and my improvements consist
in the formation and arrangement of the different parts in the construction of the
syphon cistern.
Within the cistern or tank is a partition which rises to a certain height in the
cistern and may be cast in one with the cistern or the partition may be made
independently and fixed to the cistern in suitable manner.
any
In the lower part of the partition is an inlet forming a water way and covering
this inlet is a flap or door pivotted or otherwise suitably connected to the
partition.
An outlet is also formed alongside the trapped inlet in the partition and in
connection with this outlet is the stand-pipe or syphon pipe the long leg of which is
attached to the supply pipe in the ordinary way.
A bell or plunger actuated by a lever works within the partitioned off portion so
that when a flush of water is required the lever being actuated by a chain or other
lever connection, picks up the bell or plunger thus allowing the flap or door to
open, and upon the bell or plunger descerding the flap or door is closed, and the
water contained within the partitioned off portion is forced up the short leg of the
syphon pipe and into the stand pipe, thereby displacing the air within the pipe and
thus creating a vacuum, whereby syphonic action is set up and will not cease until
the whole contents of the cistern is exhausted.
The cistern will then refill as in the ordinary manner, governed by a ball valve
and float and will be ready for the next flushing.
The cistern is provided with the usual outlet to carry off overflow.

COMPLETE SPECIFICATION.
Improvements in Syphon Flushing Cisterns and Water Waste
Preventers.
I, HENRY CRANE Junior of 183, Moseley Street Birmingham in the County of
Warwick File Manufacturer, 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 a method for flushing w.c.'s, urinals and such like, where
a flush of water in a given quantity may be required and my improvements consist
in the formation and arrangement of the essential parts required in the construction
of syphon cisterns, the object of my invention to produce an effective and rapid
automatic syphoning action together with the prevention of waste of water
supply.
Within the cistern or tank is a partition rising preferably somewhat higher in its

page_text: centre than the sides thereof which partition may either be cast with the cistern or
made independently and fixed therein in any suitable manner.
In the lower part of the partition is an inlet forming a water way and covering
and trapping this inlet is a flap or trap door which may be pivotted or hinged
suitably to the partition. An outlet or water-way is formed alongside of the
trapped inlet in direct communication with the shorter leg of the syphon pipe, this
water way is formed partly in the partition and partly in a recessed portion of the
cistern made for the purpose, the long leg of the syphon is connected to the delivery
pipe in the ordinary way. A plunger actuated by a lever works within one of the
compartments and upon the plunger, being raised the trap door is allowed to
open. Upon releasing the lever plunger descending.causes the trap door to close
and the water in the compartment is forced up the short leg of the syphon and
into the stand pipe displacing the air within the syphon and setting up the
syphonage.

Referring to. the accompanying drawings

(a) is: thestrap.door covering inlet to chamber and (b) outlet leading to syphon
pipe (c). (d) partition.
An alternative arrangement of the general principle of my invention is shewn by
which dispense with the before mamed trap door and by preference I use this
second arrangement or modification of my improvements.

Figure, 7, a form of plunger...
Within the cistern A is the syphon pipe B, the long leg of which is connected to
the delivery pipe G, from the cistern to the w.c. basin, the short leg D of the
syphon is by preference bell mouthed E, as shewn a partition wall F., divides off a
portion of the cistern, beneath this partition a water way G leads from one
compartment to the other and communicates immediately below the bell mouth E
of the short leg D. of the syphon; the floor of the cistern is sunk to a lower level H
to provide for the before named water way G a plunger Lis actuated by a lever J
and chain or other attachment K the lever may be of the formation shewn as being
suitable for this arrangement.
The water supply to the cistern is obtained in the usual manner by inlet pipe L
and is governed by ball valve and float M and N, overflow is carried away by waste
pipe O.
The normal condition of the cistern is seen in Figure 2.
The action is thus. The lever. J upon being depressed at its one end picks up
the plunger I, raising it to about the height seen in Figure, 2, the supply of water
within the cistern is thus acted upon the plunger descending by the release of the
chain and lever the water is caused to flow through the water way G and thus is
forced up the bell mouthed short leg E of the syphon which as it rises, displaces the
confined air within the syphon pipe thereby causing a vacuum and producing
immediate syphonage, whereby the whole contents of the, cistern is delivered, down
the stand or syphon pipe and thence to the w.c. or urinal basin thus thoroughly and
rapidly, cleansing the same, and not only is an effective system obtained whereby
waste, of water is,prevented but a simple arrangement provided.
..
A feature of my invention also lies in the fact of the rapidity with which the
cistern, discharges itself.
I am aware that partitions have been used for dividing the cistern into compart-
ments and therefore I do not lay any claim to the same except in connection with
my.method and improvements.
Modifications of my invention in its present form may be adopted without any

page_text: departure from the main principle of the same and I do not confine myself to the
precise character of the details as herein set forth.
Having now particularly described and ascertained the object and nature of my
said invention and in what manner the same is to be performed, I declare that what
I claim is,
The improvements in syphon flushing cisterns and water waste preventers and the
particular construction and arrangement of the several parts, or any mere equivalents
thereof, all operating in manner and for the purpose, substantially as herein set forth
and illustrated.
