Improvements in Flushing Cylinders for Water Closets.
I, DANIEL HURST, of 9, Grange Road, Pendleton, near Manchester, Plumber,
do hereby declare the nature of this invention to be as follows:-
-
My said invention relates to improvements in the construction of the flushing
cylinders or cisterns described in the Specification of my Patent No. 3267 of 1896
in which the rush of water is increased by the expansion of air which is compressed
during the filling of the cylinder or cistern.
The first part of my said invention relates to the construction of the cylinder or
cistern itself. I form the cylinder of a tube of lead having ends preferably dished
of lead and of sufficient thickness which are soldered or otherwise secured to the
ends of the tube forming the cylinder. This is inserted in a tube of somewhat
larger diameter made of sheet iron or steel. The space between the inner and
outer tubes is packed with concrete. By this means I obtain a cylinder which
while being very light is capable of resisting the pressure to which it is subjected
in use and is at the same time cheaply constructed.
Air and water tubes and valves are applied as described in my former Specifica-
tion herein referred to.
In a cylinder such as described I insert the water pipe through the centre of the
bottom end of the cylinder. The air pipe issues from one side of the cylinder so
that the part of the cylinder above the air pipe forms the air space in which the
air is compressed by the rising water after the closing of the automatic valve.
A second part of my present invention relates to means for providing an after-
flush or slow delivery of water after the cylinder has discharged the main flushing
supply of water. This I accomplish by causing the water pipe to extend inside the
cylinder some inches from the bottom end of the cylinder. Quite close to the
bottom of the interior of the cylinder the water pipe has one or more small per-
forations through which the water (which lies in the cylinder below the end of the
water pipe) can trickle after the main flushing supply has been delivered.

I, DANIEL HURST, of 9, Grange Road, Pendleton, near Manchester, Plumber,
do hereby declare the nature of this invention and in what manner the same is to

page_text: be performed to be particularly described and ascertained in and by the following
statement:
My said invention relates to improvements in the construction of the flushing
cylinders or cisterns described in the Specification of my Patent No. 3267 of 1896
in which the rush of water is increased by the expansion of air which is compressed
during the filling of the cylinder or cistern.
In order that my said invention may be more clearly understood I will describe
the same with reference to the accompanying drawing which shows in sectional
elevation a cylinder or cistern constructed in accordance with my said invention.
The first part of my said invention relates to the construction of the cylinder or
cistern itself. I form the cylinder of a tube of lead a having ends 6 preferably
dished of lead of sufficient thickness soldered or otherwise secured to the ends of
the tube forming the cylinder. The tube a is inserted in a tube c of somewhat
larger diameter made of sheet iron or steel. The space d between the two tubes ac
is packed with concrete cement or the like filling or packing. By this means I obtain
a cylinder which while being very light is capable of resisting the pressure to which
it is subjected in use and is at the same time cheaply constructed.
Air and water tubes and valves are applied as described in my former Specifica-
tion herein referred to.
In a cylinder such as described I insert the water pipe e leading from the water
main through the centre of the bottom end of the cylinder. The air outlet pipe
with its valve may be applied either at the side as indicated in dotted lines at for
in the top as indicated at f' in which case it dips sufficiently far into the cylinder
as to leave an air space above its end. The upper part of the cylinder above the
entrance to the air pipe forms the air space in which the air is compressed by
the rising water after the water has closed the air pipe. I thus dispense with the
separate air vessels shown in my said former Specification.
A second part of my present invention relates to means for providing an after-
flush or slow delivery of water after the cylinder has discharged the main flushing
supply of water. This I accomplish by causing the water pipe e to extend inside
the cylinder some distance from the bottom end of the cylinder. Quite close to the
bottom of the interior of the cylinder the water pipe c has one or more small per-
forations g through which the water remaining in the cylinder below the end of
the water pipe e can trickle after the main flushing supply has been delivered.
Having now particularly described and ascertained the nature of my said inven-
tion and in what manner the same is to be performed I declare that what I
claim is:
1. A flushing cylinder for water closets consisting of an inner and outer tube a c
having ends secured thereto and a packing of concrete or the like between the
two tubes, substantially as and for the purpose set forth and shown.
2. A flushing cylinder for water closets so combined with the air outlet pipe
that the upper part of the cylinder itself forms the air compression vessel sub-
stantially as set forth and shown.
3. The combination with the flushing cylinder or cistern of a water closet of a
water pipe e extending inside the cylinder and having perforations g substantially
as and for the purpose set forth and shown.
