Year: 1880

page_text: LETTERS PATENT to William Stainton, of 26, Liverpool Street, King's Cross,
in the County of Middlesex, Hot Water Engineer, for an Invention of
"IMPROVEMENTS IN PUMPING VALVES FOR HOT WATER APPARATUS."
PROVISIONAL SPECIFICATION left. by the said William Stainton at the
Office of the Commissioners of Patents on the 20th November 1880.
WILLIAM STAINTON, of 26, Liverpool Street, King's Cross, in the County of
Middlesex, Hot Water Engineer. "IMPROVEMENTS IN PUMPING VALVES FOR HOT
WATER APPARATUS."
This Invention relates to improvements in what are known as "pumping valves"
used in connection with hot water apparatus when charging the same with
-liquid.
In carrying out my Invention I employ a four-way piece connecting by two of
the ways with the circulating pipes, the other two ways serving for the pump
connection and the discharge respectively; the valve employed may be of the
ordinary construction, but is so placed that directly the pump is put in action the
valve falls to its seat so as to close the passage and allow the water or other liquid
to be forced through the whole system and be discharged through the discharge
opening; to raise the valve and keep it raised when the pumping is finished I
adapt to the screw cap or plug which closes the discharge passage a rod or spindle
of sufficient length to come against and raise the said valve into the chamber.or
way above so as to keep it clear of the circulating passage; this arrangement also
allows of the pump being disconnected without much discharge or loss of the water
or other liquid..

WILLIAM STAINTON, of 26, Liverpool Street, King's Cross, in the County of
Middlesex, Hot Water Engineer. "IMPROVEMENTS IN PUMPING VALVES FOR HOT
WATER APPARATUS."
This Invention relates to improvements in what are known as "pumping
valves" or "pumping pieces" used in connection with hot water apparatus when
charging the same with liquid.
In carrying out my Invention I employ a four-way piece connecting by two of
the ways with the circulating pipes, the other two ways serving for the pump
connection and the discharge respectively; the valve employed may be of ordinary
construction, but is so placed that directly the pump is put in action the valve is
forced to its seat so as to close the passage and allow the water or other liquid to
be forced through the whole system and be discharged through the discharge
opening; to raise the valve and keep it raised when the pumping is finished I
adapt to the screw cap or plug which closes the discharge passage a rod or spindle
of sufficient length to come against and raise the said valve into the chamber or
way above so as to keep it clear of the circulating passage; this arrangement also
allows of the pump being disconnected without much discharge or loss of the water
or other liquid.
.
.
But to make my Invention better understood I will proceed to describe the same
by reference to the accompanying Drawing, in which Figure 1 is a section of a
pumping valve for hot water apparatus constructed according to my improvements,
the valve being shewn open and in the position it occupies when the hot water
apparatus is in its ordinary working condition. Figure 2 is a similar view of the
same valve shewing the valve in the position it occupies when the apparatus is
being pumped, the screw cap or plug being removed.
a, b, c, d, is the four-way piece of ordinary construction, the ways a and b
connecting with the circulating pipes, the way c serving for the pump connection,
and the way d for the discharge. Instead of placing the valve e (which may be a
spindle valve of ordinary construction) with the spindle downwards as hitherto, I
reverse the position of the four-way piece and the valve, and place them as shewn
in the Drawing. f is the screw cap or plug for closing the discharge way d;
g, soft metal packing in the cap f to ensure a tight joint; h is the rod or spindle,
preferably of metal, fixed to the cap f for the purpose hereinafter described; or
the said rod h may be fixed to the valve e, or be placed loosely in the four-way
piece.
.
Although in the Drawing I have shewn a spindle valve as being the most
suitable it will be understood that a ball or other valve may be employed.
By this construction of pumping valve it will be seen by reference to Figure
that when the cap or plug fis screwed on the way d the upper end of the rod h
will come against the lower part of the valve e and raise it from its seating i into
the way c, and leave the passage open through the ways a and b, so as in no way
to impede the circulation. When however it is required to pump or force water
through the apparatus to cleanse it, or for other purposes, a pump is connected to
the way c, and the cap or plug f being removed, the valve e will fall (or be forced
by the pump) into its seat i, as shewn in Figure 2, and the pump being put in
action the liquid will be forced through the apparatus, and will pass in the direction
shewn by the arrows in Figure 2, and be discharged through the way d, to which
a pipe may be attached so as to carry away the discharged liquid. It will also be
seen that should the valve from any cause stick in the way c when the cap or

page_text: plug f has been removed it would be forced to its seat by the action of the pump
which forces the liquid directly on the valve, thereby effectually closing the
connection between the passages a and b, allowing a free passage of the liquid from
the pump through c and b, as shown by the arrows, and ensuring a thorough
circulation of the liquid through the whole system of circulating pipes. The liquid
returns through a, and is discharged through d, as shewn by the arrows.
The pumping being completed, the cap or plug f is screwed on so as to close the
discharge way d, and the rod h will raise the valve, as herein before described, into
the position shewn in Figure 1, and keep the circulating passage clear.
This arrangement also allows of the pump being disconnected with but little
discharge or loss of the water or other liquid.
Although in the Drawing I have shewn the valve as placed vertically, it will be
understood that it may be placed horizontally.
Having thus described my said Invention, and the best means with which I am
acquainted for carrying the same into effect, I would have it understood that I do
not confine myself to the precise details herein laid down, as the same may be
varied without departing from the peculiar character of my Invention, but what I
claim is,-
Firstly. The construction and employment of the improved "pumping valve" or
ແ "pumping piece" for hot water apparatus arranged and operating substantially as
herein before described and represented in the accompanying Drawing.
"
Secondly. In a "pumping valve " or piece for hot water apparatus I
claim the combination of the rod h and valve è, as and for the purpose specified.
In witness whereof, I, the said William Stainton, have hereto set my hand
and seal, this Nineteenth day of May, in the year of our Lord One
thousand eight hundred and eighty one.
