Improvements in Automatic Valve Attachments as applied to

I, JOSEPH WINTERFLOOD, Gas Engineer, of 173, Kings Road, Camden Town,
London, do hereby declare the nature of this invention to be as follows.-
-
This invention relates to certain improvements in automatic valve attachments
as applied to water heaters known as geysers, wherein the gas supply 18 regulated
or controlled by the opening and closing of the water supply cock
For the purpose of this invention I employ a double chamber the two cavities of
which are separated by a metallic diaphragm
In the upper chamber there is as water inlet and outlet and in the lower chamber
there is a gas inlet and outlet
The gas and water inlets are closed or controlled by valves connected on opposite
ends of a spindle passing through the centre of the diaphragm
The water valve consists of a rubber disc the outer edge of which is fixed to
the wall of the chamber. The said rubber disc has a hole in its centre through
which passes a small tube fixed to the under surface of a plate
The said plate is fixed to the spindle, and to the rubber disc by means of a
washer which fits over the tube
The lower end of the said tube works in an outer tube The outer tube is fixed
at its lower end to the wall of the chamber below the water inlet and above the
water outlet,
A projection is fixed to the spindle at such a distance above the diaphragm as
to admit of the application of a rubber bellows
In the upper chamber and above the rubber disc I fix a spring one extremity
to the upper plate and the other extremity to the top of the chamber, and in the
top of the chamber I drill a small hole the purpose of which is to allow the air
out when the disc rises

This invention relates to certain improvements in automatic valve attachments,
as applied to water heaters known as "Geysera "wherein the gas supply 18 regulated
or controlled by the opening and closing of the water supply cock.
For the purpose of this invention I employ a double chamber the two cavities
of which are separated by a metallic diaphragm. In the upper chamber there a
a water inlet and outlet and in the lower chamber there is a gas inlet and outlet.
The gas and water inlets are closed or controlled by valves connected to the
opposite ends of a spindle passing through the centre of the metallic diaphragm
As shewn in the annexed drawing of which Fig 1 18 a' sectional elevation when
closed and Fig 2 is a sectional elevation when open, the automatic valve attach-
ment consists of a double, chamber the two cavities of which are separated by a
metallic diaphragm, 1
In the upper chamber there is a water inlet 2 and outlet 3, and in the lower
chamber there is a gas inlet 4 and outlet 5. The gas and water inlets are closed
or controlled by valves 6 and 7 which are connected to the opposite ends of tho
spindle 8 passing through the centre of the metallic diaphragm 1.
The water valve 7 in the upper chamber consists of a rubber disc 9 the outer
edge or cucumference of which is fixed to the wall of the chamber The said
rubber disc is fixed to the spindle by two plates, and a tube 10 18 fixed to the
centre of the plates. The lower end of the tube 10 works in a tube 11 of slightly
greater diameter, the lower end of this outer tube 11, being fixed to the wall of the
chamber above the water outlet 3 and below the water inlet 2, the upper chamber
thereby being partitioned into two parts the water way of which 18 governed or
controlled by the valve 7.
A series of small holes 12 are drilled in the lower end of the inner tube 10 and
a small hole 13 is drilled in the outer tube 11, the purpose of which is hereinafter
described
:-
The action of the automatic valve attachment may be described as follows:-
When the operator opens the water supply cock, the water enters the upper
chamber at the inlet 2 and on filling the cavity between the tube 11 and the wall
of the chamber, it exerts a pressure upon the rubber disc 9 of the valve 7, thereby
forcing it up and consequently the inner tube 10 rises and allows the water to
issue through the series of holes 13 to the water outlet 3.
When the rubber disc rises it 18 apparent that the gas valve 6 will simul-
taneously rise in consequence thereof and allow the gas to pass through from the
inlet 4 to the outlet 5.
When the operator closes the water supply cock, the water in the cavity between
the tube 11 and the wall of the chamber flows out until the water falls to the level
of the hole 13. The pressure is now released from the rubber disc which conse-
quently drops to its normal position and accordingly the gas valve simultaneously
drops upon its seating thereby closing the gas way.
I provide a rubber bellows 14 in the upper chamber which is fixed to the metallic
diaphragm 1 and a projection 15 on the spindle The purpose of this rubber
bellows 14 is to prevent the gas from leaking through the diaphragm and con-
taminating the water.
In the upper chamber above the valve 7 I drill a small hole 16 the purpose of
which is to allow the air to pass out when the rubber disc rises.
When the above mentioned valve attachment 18 attached to a water heater or
"Geyser" wherein the level of the water is above the top of the valve attachment
the upper chamber would always be full of water and therefore there would be a
continual upward pressure upon the valve 7 tending to keep it open, to counter-
act this I employ a spring 17 in the upper chamber above the valve 7 the strength
of which is great enough to overcome the back-pressure of water.

page_text: Having now particularly described and ascertained the nature of this inven-
tion and in what manner the same is to be performed I declare that what I
claim 18,-
1 The improvements in automatic valve attachments consisting of a valve con-
structed of a rubber disc, fixed to the wall of a chamber and arranged with plates
and tubes substantially as and for the purpose herein set forth described and
illustrated
2. The improvements in automatic valve attachments as applied to water heaters
known as geysers consisting of a double chamber the two cavities of which are
separated by a metallic diaphragm the upper chamber containing a water inlet
and outlet the lower chamber a gas inlet and outlet, in combination with a valve
consisting of a rubber disc arranged with plates and tubes and fixed in the water
chamber to a spindle which ia in connection with a valve in the lower chamber,
a rubber bellows, and a spring arranged in the upper chamber above the valve
through the wall of which is a small hole all substantially as and for the purpose
herein set forth described and illustrated.
