Improvements in Waste Preventers or Flushing Cisterns.
RICHARD Fox Zinc Worker 786 Old Kent Road Peckham S.E. do hereby
declare the nature of this invention to be as follows :-
This invention consists of combination valves to closed cistern as hereinafter
described.
In order to carry out this invention although it is possible to make the outer case
or cistern of wrought iron or other metal, I prefer to make it of cast iron of such
a thickness as will stand high pressure usual to high pressure mains. The outer-
case or cistern is made of cast iron closed at top by a cover which is secured by
means of bolts which slip in slots cast out of top of cistern and to which is attached
to top of cistern or cover an automatic relief valve as hereinafter described. At
the bottom of the aforsaid cistern is fixed a valve seating of brass and to which is
also fixed a cast iron syphon as hereinafter described. And on the underside of
valve seating is screwed for backnut and the whole secured by suitable packing to
stand pressure.
The syphon consists of an internal cylinder and an external
cylinder. In the internal cylinder contains a four way rim valve spindle to which
is attached on the bottom a leather disc secured by a screw with metal washer
which seating on the aforsaid valve seating closes the bottom of the cistern until
required for use or to discharge its contents. The aforsaid internal cylinder of
syphon is enlarged at bottom to allow the water to pass more freely by the leather
disc or valve. The external cylinder of the cyphon is straight and of sufficient
diameter to allow the water to pass the enlarged part of the internal cylinder. At
the top of the external cylinder is fixed a rod which passes through the automatic
relief valve as hereinafter described. The aforsaid rod after passing through the
automatic relief valve cylinder is attached to lever in the centre and at the one
end is attached a weight of cast iron of sufficent weight for more securely closing
the valve in syphon and at the other end is attached a chain for working the
syphon and automatic relief valve as hereinafter described. The automatic relief
valve as aforsaid consists of a cylinder cast with a screw each end and at the
bottom of cylinder is a washer with backnut attached through which the rod as
aforsaid passes with two cup leathers with a metal washer between forming a solid
plunger or piston. The object of which is when not in use to retain pressure in
cistern and when in use to supply cistern with air. At the top of automatic relief
valve cylinder it is screwed on the outer side and enlarged on the inside so that
when the rod of the syphon has passed through, two metal washers packed with
soft cotton are passed over the rod into the enlarged part of cylinder to a sufficient
depth to form stuffing box and secured by means of a put or cap screwed on the
outside to keep metal washers and packing from getting out of their place. At
half-way up the cylinder there are a number of holes drilled through to admit air
into the aforsaid cistern also to let water out should it be necessary through air
concussion or sudden pressure, therefore relieving the aforsaid cistern and at the
same time supplying air. Over the outside of the automatic relief valve cylinder
is passed a metal casting which has a chamber or grouve round its internal diameter
which is fixed at such a position that the. holes in the automatic relief valve
cylinder are opposite and from which air is drawn or water discharged as the case
may be. On the outside of the aforsaid casting is an outlet leading from the
chamber or groove which is screwed so that to it may be fixed a pipe through
which to pass away any water that may collect or give warning of the same.

Improvements in Waste Preventers or Flushing Cisterns.
I, RICHARD Fox of 786, Old Kent Road, Peckham, in London, Inventor and
Patentec, 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 :-
In order to carry out this invention which is illustrated by a vertical section 1
make the outer case or cistern g of wrought iron or other metal; I prefer to make
it of cast iron of such a thickness as will stand high pressure usual to high pressure
mains. The outer case or cistern 9 is made of cast iron closed at the top by a
cover o secured by means of bolts which slip in slots cast out of the top of the
cistern and is fixed to top of cistern or cover with an automatic relief and feed
valve as hereinafter described. At the bottom of the aforesaid cistern is fixed
a valve seating p of brass and also a cast iron syphon as hereinafter described.
And on the under side of valve seating is screwed a back nut and the whole secured
by suitable packing to stand the pressure.
The syphon consists of an external cylinder and internal cylinder m. In the
internal cylinder is a four way rim valve spindle to which is attached on the bottom
a leather disc n secured by a nut and metal washer, which seats on the aforesaid
valve seating p, closes the bottom of the cistern until required for use, or to
discharge its contents.
The
The aforesaid internal cylinder m of syphon is enlarged at bottom to allow the
water to pass more freely by the leather disc or valve. The external cylinder / of
the syphon is straight and of sufficient diameter to allow the water to pass the
enlarged part of the internal cylinder. At the top of the external cylinder is
fixed a rod k which passes through the automatic relief and feed valve as herein-
after described. The aforesaid rod after passing through the automatic relief
valve cylinder is attached to a rod c by a coupling i with a spring f in the centre
and at the one end is attached a weight of cast iron of sufficient weight for more
securely closing the valve in syphon and at the other end is attached a chain for
raising the rod c to operate the syphon and automatic relief and feed valve as
hereinafter described. The automatic relief and feed valve as aforesaid consists
of a cylinder cast with a screw each end and at the bottom of cylinder is a washer
with back nut attached through which the rod as aforesaid passes with two cup
leathers d with a metal washer between forming a solid plunger or piston.
object of which is when not in use to retain pressure in cistern and when in use to
supply cistern with air in the air space e. The top of automatic relief and feed
valve cylinder is screwed on to the outer side and enlarged on the inside so that
when the rod of the syphon has passed through two metal washers packed with
soft cotton are passed over the rod into the enlarged part of cylinder to a sufficient
depth to form a stuffing box and is secured by means of a nut or cap screwed on
the outside to keep metal washer and packing from getting out of their place. At
halfway up the cylinder there are a number of holes drilled through a disc to
admit air into the aforesaid cistern also to let water out should it be necessary
through air concussion or sudden pressure therefore relieving the aforesaid cistern
and at the same time supplying air. On the inside of the aforesaid automatic relief
and feed valve cylinder, it has a chamber or grooves cast divided into two, one
half supplying water to feed the aforesaid cistern and the other half chamber
supplying air into which as aforesaid the holes are drilled. On the outside of the
aforesaid casting of automatic relief and feed valve is an air outlet leading from

page_text: the chambers or grooves which is screwed so that a pipe may be attached to pass
away any water that may collect or give warning of the same and also the outlet
from feed chamber is screwed to admit pipe to be attached. From the feed chamber
in the aforesaid automatic relief and feed valve there is a slot cast out to meet
chamber to allow the water to feed cistern. And to the aforesaid rod in cistern is
a movable disc h of metal with leather washer n attached and through the side of
metal disc a number of holes are drilled so that when the cistern is required to
discharge itself it will at the same time shut the water off from main pipe or inlet a
and feed the cistern with air. j is the water line. The way the water travels from
the supply a to the valve seating p is indicated by arrows.
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 waste preventer or flushing cistern, the combination of the inlet a, air
pipe b, rod pull, cup leathers & spring f, metal disc h, coupling i, rod k, external
cylinder, internal cylinder m, leather washers n, cover o and valve seating with
the sealed cistern g, substantially as herein described and according to the accom-
panying drawing.
2. In a waste preventer or flushing cistern, the combination of the construction
of the mechanism, without the aid of a ball valve, substantially as herein described
and according to the accompanying drawing.
3. The combination of an automatic relief and feed valve to sealed cistern
or tank, substantially as herein described and according to the accompanying
drawing.
