PROVISIONAL SPECIFICATION.
Improvements in Sanitary Flushing Apparatus.
GEORGE FREDERICK MATTHEWSON, 200, Alfreton Road, Nottingham, Tin and
Copper Smith, do hereby declare the nature of this invention to be as follows:-
This invention relates to improvements in the flushing apparatus used for
sanitary purposes, and has for its object more especially the instant release of the
flushing water, and filling up of the same automatically, without noise.
In carrying out this invention the ** push cock" (as used in fountains) is
employed, and is worked by means of a bar lever, this bar lever has its short
end hinged near to the push cock, its long end is attached by means of a chain,
or other suitable connection, to the back of a turning pan, this turning pan
may be made in any convenient form so as to turn or revolve upon an axle at
either end, these said axles are fixed a little out of the centre, a regulating
weight being fastened to the back of the turning pan so as to throw it more out
of the centre, inside the turning pan running from one end to the other, is fixed
a partition, this partition dividing about one quarter of the area of the said turn-
ing pan, the top does not reach quite to the top of the turning pan, both of which
are open at the top, the turning pan works and turns on its axles inside a larger
outer casing, a hole in the bottom of this outer casing through which, when the
water is released, flows to the basin below.
The short end of the said bar lever is continued untill it hangs over the side
of the outer casing a chain, or other suitable connection being fastened to this
end of the bar lever, which hangs down to within reach of the hand.
The action of the arrangement is as follows:-The weight of the bar lever
assisted by the weighted turning pan, opens the push cock filling up the turning
pan, then overflowing and filling the partition, the weight of water in this
partition, balances the turning pan, allowing it, along with the bar lever, to rise
a little thus stoping the push cock.
When it is required to flush the basin, the outer chain (or other suitable con-
nection) with its lever is pulled down, this being in connection with the back
of the turning pan, as described above turns all the water into the outer casing,
thence through the hole at the bottom into the basin, the weight on the back
of the turning pan, bringing it back again into its original position.
The same arrangement is used as a means of measureing water by connecting
an ordinary indicator to the turning pan, so that it may register each pan of
water.
Again, the water pipe leading from the said push cock, may have a small pipe
fitted with a regulating tap, leading to the turning pan, by this means a large
quantity of water may flow for flushing purposes &c. untill the turning pan has
sufficient water in it, to balance it, thus releasing the bar lever and stoping the
push cock.
The said push cock may be used with a float in any kind of cistern, also the
said turning pan may replace the float for the ordinary ball tap.

GEORGE FREDERICK MATTHEWSON, of 200, Alfreton Road, Nottingham, Tin
and Copper Smith, 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:-
This invention relates to improvement in flushing apparatus for water closeis
and for other sanitary purposes, the object of the invention being improvements
in the construction and arrangement of flushing apparatus designed to give an
instant release of the flushing water.
الانه :
According to this invention a cistern or tank is fitted with a pivotted tipping
bucket which is supplied with water by a "push" or a "ball" valve and the
parts are so arranged that when the tipping bucket is empty, it acts upon the
valve and opens the same and when the tipping bucket is full it moves into a
position to close the valve or allow of the valve being closed by a weight or a
spring and is held in such position by a catch lever or the like connected to the
handle. In a flushing apparatus fitted with a "push" valve this latter is attached
to the side of the cistern and one end of the valve lever is. connected to the
handle, while the other end of the lever extends across the cistern and is made
with catches which engage with the tipping bucket to open and close the valve
or allow of the valve opening and closing according to the position of the bucket,
or there may be a flexible connection between the bucket and the valve lever.
When this invention is applied to a flushing arrangement fitted with a ball
valve, the latter is fixed at one end of the cistern and is closed by a weighted
lever and opened by the tipping bucket acting on such lever. In this arrange-
ment a weighted catch lever is used and so arranged that when the bucket moves
to allow of the valve being closed, it is held in such position untill released from
the handle.
The parts are suitably pivotted and weighted, and the time at which the tipping
bucket opens the supply valve may be regulated by a water reservoir inside the
bucket.
In the drawings which accompany this specification and are referred to in the
following description
Fig. 1 is a section of the improved flushing apparatus. fitted with a push
valve.
Fig. 2 is a section of the improved flushing apparatus fitted with a ball valve.
In the arrangement shown on Fig. the tipping bucket a of approximately
the shape shown is pivotted at 6 at the ends of the cistern c. At a convenient
position on one side of the cistern the push cock d is fixed and is connected
at e to the water supply pipe. This valve is closed by a spring and opened by
a lever which is pivotted at f and provided with an arm g for operating the valve,
a second arm h which is connected to the handle and a third arm which extends
across the bucket and is provided with catches 7 and . These parts are arranged
substantially as shown and the bucket is so pivotted and weighted that when
empty its upper edge is in the position of the dotted line m and is held in that
position by the catch the weight of the bucket at the same time acting upon
the lever k to open the valve d. As the bucket fills the water balances therweight
and the bucket moves until its top comes into contact with the catch the
valve d closes and the parts remain in this position until the lever his operated
and the bucket released and the water therein discharged. into the cistern c from
which it is conveyed by a pipe to the part to be flushed. In a modification of

page_text: this arrangement the catches and are dispensed with, and the end of the
lever k is connected to the side of the bucket by a chain or similar flexible con-
nection, and the bucket is so weighted that when empty it pulls down the lever k
to open the valve, and the tipping of the full bucket is then started by a pull
on the lever h.
In the arrangement shown in Fig. 2 the bucket a is pivotted in a cistern c
similarly to the arrangement shown in Fig. 1. In this second arrangement an
ordinary ball valve n is fixed to one end of the cistern and it lever o is provided
with a weight 2 which closes the valve when the bucket top is on the line g. The
valve is opened by the bucket when it returns empty and is on the line r, the
position of the pivot b and the weighting of the bucket being arranged accord-
ingly. When the bucket is full and its top lies on the line q, a pin on the
end of the same comes into contact with a catch s on a weighted levert which is
pivotted on the end of the cistern and connected to the handle by the arm u.
In this arrangement, when the lever t is operated, the catch s is moved clear
of the pin and the further movement of the lever starts the turning of the
bucket on its pivot b, and by varying the position of the pin e, or by indenting
the inner edge of the lever t, they may be so arranged that the bucket cannot
be tipped until it has received a definite quantity of water.
The cisterns in both arrangements are provided with a dash plate w to prevent
the water discharged from the bucket dashing up the side of the cistern, and
in order to regulate the speed with which the bucket returns to its original posi-
tion it may be provided with a partition or reservoir a which is of such a size
relatively to the weighting of the bucket, that the water in it prevents the bucket
making the whole of its return movement, until such water runs out of the
reservoir and restores the equilibrum of the bucket.
Having now particularly described and ascertained the nature of my said
invention, and in what manner the same is to be performed, I declare that what
I claim is:
1. A flushing apparatus constructed arranged and operating substantially as
herein described with reference to Fig. 1 of the accompanying drawings.
2. A flushing apparatus constructed arranged and operating substantially as
herein shown and described with reference to Fig. 2 of the accompanying draw-
ings.
