PROVISIONAL SPECIFICATION.
Improvements in Water Closet Cisterns.
I NORMAN LINES of 7 Guildford Street Luton, in the County of Bedford
Mechanical Engineer do hereby declare the nature of this invention to be as
follows:-
The object of this invention is to simplify the construction of water closet
cisterns and to prevent waste of water.
The improvements consist in the construction of a closed cistern having a
flexible diaphragm (without an opening in it) fixed in the cistern by constructing
the cistern in two parts and bolting the parts together with the diaphragm between
to make a water tight joint.
The cistern is provided with an inlet hole below the diaphragm-
-an air hole in
the top above the diaphragm, and a flushing valve at the bottom. The valve is a
solid ball fitting a suitable seat, it is raised for flushing purposes by means of a
spindle fitted through a stuffing box below the valve seat and across the outlet
hole, the spindle is provided with a crank to which a rod is connected, the rod
works vertically in the outlet hole, on the end of the rod a dish is fixed to fit the
ball. A weighted lever is fitted to the spindle, the weight keeping the dish from
touching the ball. Inside the cistern a pipe is fitted to the inlet hole across the
top of the outlet valve; in such a position that when the ball is raised it comes in
contact with the pipe, at the point of contact a small hole is made to admit the
water, so that when the ball is raised for flushing purposes it is pressed against the
inlet hole closing it. The action of the cistern in work is as follows, the water
enters below the flexible diaphragm, when the cistern is full the diaphragm is
pressed to the shape of the upper part of the cistern and closes the air hole at the
top. To empty the cistern the weighted lever is pulled down the dish is brought
into contact with the ball lifting it from its seat. The elasticity of the diaphragm
and the atmospheric pressure of air acting on the diaphragm force the water out of
the cistern with good flushing power.

Improvements in Water Closet Cisterns.
I, NORMAN LINES, of 7 Guildford Street, Luton, in the County of Bedfordshire,
Engineer, 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 improvements in water closet cisterns, and has for its
object to simplify the construction of water closet cisterns and to prevent waste of
water

with the diaphragm d between to
The cistern is provided with an inlet hole below the diaphragm d, an air hole
or holes in the top a above the diaphragm d, and a flushing valve at the bottom 7.
The valve is a solid ball fitting a suitable seat j, it is raised for flushing purposes
by means of a spindle o fitted through a stuffing box below the valve seat and
across. the outlet hole; the spindle o is provided with a crank o' to which a rod n
is connected by joints m, the rod n works vertically in the outlet hole. On the
end of the rod na disk k is fixed to fit the ball. A weighted lever p is fitted to
the spindle o, the weight keeping the disk & from touching the ball i..
Inside the cisterne a pipe fis fitted with a cup and an inlet hole g across the
top of the outlet valve, in such a position that when the ball i is raised it comes in
contact with the cup 7, at the point of contact a small hole g is made to admit the
water, so that when the ball is raised for flushing purposes it is pressed inside the
cup against the inlet hole and closing it.
g
The action of the cistern in operation is as follows:-
g
The water enters by the hole below the flexible diaphragm d, when the cistern
is full the diaphragm d is pressed to the shape of the upper part a of the cistern e
aud closes the air holes 6 at the top. To empty the cistern the weighted lever p is
pulled down by a chain and ring, the disk is then brought into contact with the
ball lifting it from its seat into the cup to close the opening g.
on
The elasticity of the diaphragm d and the atmospheric pressure of air acting
the diaphragm dforce the water out of the cistern é with a heavy flushing
power.
Flushing pipe is connected to the base of the cistern by a union s.
It will be understood that the shapes, materials and proportions of the various
parts may be varied in many ways within the scope of my invention.
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. In a flushing water waste preventer, the combination of the base / cistern e
diaphragm d top a with holes b, and flanges el with bolts e, supply pipe hole g
cup and valve i and seating j disk k rod n joints m and crank o' to spindle o and
the lever p with weight q, substantially as herein described and according to the
accompanying drawing.
2. A. flushing water waste preventer, the combination of the apparatus to be
constructed of any size, of any material or with any modification of the various
parts, substantially as herein described and for the purpose set forth.
Dated this 17th day of October 1891.
