A communication from MYRTILLA CARMELIA BOOTH and JOHN OLIVER PARKER,
Brass Founder, trading under the firm name of Booth & Son, of 155, York'
Street, Toronto, in the Dominion of Canada.
I, ALFRED JULIUS BOULT of 323 High Holborn, in the County of Middlesex,
M.I.M.E., 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 to design a water-closet flushing cistern which will
be economical in the use of water, simple in its construction effective in its operation,
cannot overflow and which while discharging a large volume of water for flushing
will supply a small gentle stream for the after-wash; and it consists essentially first
of a tank or receptacle provided with a pipe leading from a point at or near its
bottom to the closet and having a water bucket pivoted within or above the tank
so that the contents of the bucket can be discharged bodily into the tank or receptacle
in order that its full volume may at once be used for flushing, means being provided
to temporarily retain a small quantity of the water to be used for the afterwash;
secondly in placing within the water bucket a chamber designed to hold the ball of the
ball-valve water being admitted into the said chamber in such a manner that the valve
will be closed when the bucket is full and will remain closed during the period that
the bucket is discharging its contents into the tank but will immediately reopen to
adinit the required quantity of water into the bucket when it is returned to its
normal position where it receives a fresh supply of water; the parts being arranged
and constructed substantially in the manner hereinafter more particularly explained.
Figure 1 is a perspective view of the improved flushing cistern partially in section
showing the bucket in its normal position.
Figure 2 is a similar view but showing the bucket upset to discharge its contents
into the tank or receptacle.
Figure 3 is a sectional side elevation of Figure 1.
A represents the tank or receptacle and B the pipe leading from the tank A to the
closet.
C is a bucket which it is preferred to pivot in the tank A as indicated in the drawing
although it would answer the purpose of the invention if it were pivoted at a point
above the said tank.
D is the pipe from which the water supply is obtained and which is provided with
an ordinary ball valve E.
A chamber F is placed within and connected to the bucket C so that it will move

page_text: On the latter's pivot. This chamber is designed to contain the ball G of the valve E
and is preferably left partially open as indicated. When there is no water in the
chamber F the valve E will of course be open permitting the water to flow from the
pipo D into the bucket C. As the level of the water rises in the bucket C it flows
through the hole a into the chamber F and by the time it has reached the desired
level sufficient water will have been admitted into the chamber F to float the ball G
and in this way close the valve E in the ordinary manner. When it is desired to
flush the closet the bucket C is upset until it assumes the position in which it is shown
in Figure 2 when its contents will of course be discharged into the tank A.
As it would not be desirable to allow the valve E to open while the bucket is being
upset the hole a in the chamber F is made at such a point that the tipping of the
bucket C to which the chamber F is attached carries the said hole above the water
level so that the water remains within the chamber F during the period that the
contents of the bucket Care being discharged into the tank A thereby holding the valve
closed so as to prevent the waste of water which would otherwise take place.
When the bucket C is permitted to resume its normal position as indicated in
Figure 1 the water immediately flows through the hole a from the chamber F into
the bucket C; consequently.the ball-valve E will open gradually and a fresh supply of
water be admitted into the bucket without noise.
In order to tilt the bucket C a lever H is provided which it is preferred to connect
to the pivot of the bucket C and thence by a chain to the handle of the closet.
On reference to Figure 3 it will be noticed that the pipe B projects into the tank A
and that a hole b is made through the pipe at a point substantially flush with the bottom
of the tank A. When the water is upset from the bucket C into the tank A it will
of course immediately flow out of the pipe B filling the said pipe and flushing the
closet with full power of its volume. When the level of the water reaches the top
of the projecting end of the pipe B the remainder of the water can only find its way
into the pipe B through the hole 6 thereby ensuring a gentle stream for the after-
wash and for filling the bowl of the closet.
Having now particularly described and ascertained the nature of the said inven-
tion as communicated to me by my foreign correspondents and in what manner
the same is to be performed I declare that what I claiin is :-
1. A tank or receptacle provided with a pipe leading from a point at or near its
bottom and having a water bucket pivoted within or above it substantially as and for
the purpose specified.
2. A tank or receptacle provided with a pipe projecting into it above its bottom
and having a hole made through the pipe substantially flush with the bottom of the
tank or receptacle in combination with a water bucket pivoted within or above the
said tank substantially as and for the purpose specified.
3. A tank or receptacle provided with a pipe leading from a point at or near its
bottom and having a water bucket pivoted within or above it in combination with a
water supply pipe provided with a ball-valve operated by the water admitted into
the bucket substantially as and for the purpose specified.
4. A tank or receptacle provided with a pipo leading from a point at or near its
bottom and having a water bucket pivoted within or above it a water supply pipe
provided with a ball-valve in combination with a chamber connected to the pivoted
bucket and having a hole in it so located that when the bucket is in its normal position
water will flow through the hole but will not do so when the bucket is upset
substantially as and for the purpose specified.
