PROVISIONAL SPECIFICATION.
Improvements in Apparatus for Supplying Water to Closets and
other places.
We, GEORGE JENNINGS and JOHN MORLEY, both of Palace Wharf, Stangate,
Lambeth, in the County of Surrey, Sanitary Engineers, do hereby declare the
nature of this invention to be as follows:-
This invention relates to apparatus in which the supply cistern is emptied by
syphoning.
In such apparatus we place the ball of the supply valve in a compartment
separated from the supply cistern by a partition reaching nearly but not quite to
the highest water level and this compartment has dipping into it the short leg of an
independent syphon whose long leg passes down inside the long leg of the main
syphon. This secondary syphon is considerably smaller than the main syphon so
that the ball compartiment takes longer to empty than the cistern and its contents
therefore act as an after flush.
When the cistern is filling the ball remains at the bottom of its compartment
(and the valve therefore remains fully open) until the cistern is almost full when
the water runs over the partition filling the compartment raising the ball and closing
the valve.
The ball is preferably connected to its lever by a universal joint and is guided
by a vertical pin fixed to the bottom of the compartment and working in a tube
through the ball.
The long leg of the secondary syphon is preferably of slightly larger diameter
than the short leg, this prevents syphonic action being set up and the compartment
being emptied by a small flow of water down the long leg of the main syphon and
insufficient to start the latter.

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 :-

DESCRIPTION OF THE DRAWINGS.
Figure 1 is a vertical section and Figure 2 is a plan showing a syphon
apparatus such as is described in the Specification No. 639 of the year 1889
but modified in accordance with the present invention.
A, A are the two compartments of the cistern separated by the partition A'.
B is the supply cock operated by the ball or float B', .the cock delivering into
the compartment A whilst the float is in the compartment A. C is a bell fixed
to the bottom of the cistern, its lower part. is of cylindrical form and it has
near the top an extension or swelling C. D is a cavity or pocket in the bottom
of the cistern below the bell, it extends in places beyond the bell. E is the
delivery pipe fixed to the bottom of the cavity or pocket D. F is an axis above
the cistern to which three arms F1 F1 and F' are fixed. GG are rods connecting
the ends of the arms F1 F' to the slider H mounted on the delivery pipe. The
top of the slider carries a table or disc J which works on the delivery pipe E
and loosely fits inside the bell C. K is the secondary syphon for emptying the
compartment A', its longer leg K¹ passes down inside the delivery pipe E as shown.
The action of the apparatus is as follows:-
When the cistern is full of water and the arm F of the lever is depressed by
pulling the chain attached to its upper end the arms F1 F1 are raised carrying
with them the connecting rods G G, the slider II and the disc J. The upward
motion of the disc J within the bell C raises the water contained in the bell
which when it reaches the top flows down the delivery pipe E, the water from
the compartment A entering the bell C and following the disc .J. When the
disc J reaches the enlargement C' the water behind it is free to pass round it
and escape down the delivery pipe E which it does, a syphon action having
been set up by the water above the disc J. This syphon action continues until
the compartment A is empty the slider then returns by its own weight to its
original position. The flow of water down the pipe E starts the syphon K and
empties the compartment A also but the syphon K being smaller than the main
syphon the compartment A empties first part of the contents of the compartment A¹
acting as an after flush. As the compartment .A' empties the float B' descends
opening the cock B which remains full open until the water flows over the
partition A and entering the compartment A raises the float.
It is to be understood that this invention is applicable to other forms of syphon
apparatus.
Having now particularly described and ascertained the nature of our said inven-
tion and in what manner the same is to be performed we declare that what we
claim is :-
:-
1. A tank divided into two compartments by a partition reaching nearly but
not quite to the highest water level, the supply valve delivering into one
compartment and the float operating the valve being in the other compartment,
the first mentioned compartment being emptied by a syphon in the ordinary
manner whilst the other compartment is emptied by a secondary syphon whose
long leg passes down inside the long leg of the main syphon substantially as
described.
2. In apparatus such as is referred to in the first claim connecting the float to
its lever by a universal joint and guiding it by a pin fixed to the bottom of the
compartiment and working in a tube through the float substantially as described.

page_text: 3. In apparatus such as is referred to in the first claim making the long leg
of the secondary syphon of slightly larger diameter than its short leg substantially
as described.
4. Apparatus for supplying water to closets and other places substantially as
5 described and shown in the drawings.
