This Invention has for its object improvements in apparatus for maintaining a
supply of boiling water or steam or of both.
For many purposes it is desirable to maintain a supply of boiling water which
can be drawn off whenever required at a boiling temperaturo from a cock or tap
at a distance from the boiler in which the water is boiled-in other cases it is
desirable to maintain a continuous supply of steam for heating purposes or to
maintain a supply both of boiling water and steam.

To effect these objects I employ a steam boiler by preference heated by a burner
adapted for burning a mixture of gas and air. By preference also I use an upright
boiler with an arched inner chamber at the bottom below which the burner is placed
and in order to increase the heating surface of this boiler I place rows of tubes
across the chamber from one side of the boiler to the other. The rows of tubes I
set one above the other at different levels and preferably I make them to cross at
right angles. Other forms of steam boiler might however be used instead of a
boiler formed in the above manner. Through the upper part of the boiler I carry
upwards a pipe from a point below the water level and fit it with a cock at its
end to allow of boiling water being at any time drawn off from it. The pipe
outside the boiler I surround by a pipe of larger diameter to which steam can
always enter freely from the boiler so that the water contained in the smaller hot
water supply pipe may always be maintained at or about the boiling point-any
water drawn off from it must therefore always be boiling because if the tempe-
rature of the water gets below the boiling point no water can be drawn off from
the cock.
This way of keeping the hot water supply pipe at or about the temperature of
boiling water right up to the cock or tap at which the water is to be drawn off is
applicable whether the boiler be heated by gas or in other ways

level I pass a spindle horizontally across the boiler through a stuffing box at one
of its sides. Inside the boiler I provide the spindle with arms to which a float is
connected. Outside the boiler I couple the end of the spindle to the plug of a cock
on the water supply pipe by which water under sufficient pressure is supplied to
the boiler. When the water level in the boiler rises to its proper height the float
rises with it and shuts off the cock. When the water level falls the float descends
with it and opens the cock.

In order to shut off gas from the gas burner whenever the pressure in the boiler
has been brought up to the point required I couple the flexible diaphragm of the
gas cock used for controlling, the supply of gas to the gas burner to a second
flexible diaphragm which closes over the enlarged end of a pipe leading from the
lower part of the boiler. This diaphragm I cause to be held up by a weighted lever
or otherwise in opposition to the pressure in the boiler but when the pressure in
the boiler overpowers the weighted lever the diaphragm is pressed outwards and
closes the gas supply cock so that whenever there is sufficient pressure in the
boiler gas is turned off from, the burner below it and whenever the pressure again
falls in the boiler the gas cock is again opened. The gas supply cock I provide
with a small bye pass tube with a small regulating cock upon it by which a small
quantity of gas may always be allowed to pass to the burner-I also provide a
small gas jet close to the main burner and supply it with gas from a separate gas
supply pipe so that it may be kept always lighted and ignite the gas at the main
burner so soon as gas is turned on to it.
I also provide the boiler-with a small safety valve loaded to a pressure some-
what exceeding the pressure required for shutting off the gas from the main gas
burner, say to a pressure of about 2 lbs to the inch.
In cases also where a continuous supply of steam is required as for example for
heating purposes I also lead off a steam pipe from the upper part of the boiler to
wherever it may be required to use the steam.

Boiling Water or Steam, or of both.
I CHARLES JONES of. 2 Lower Whitecross Street in the City of London Builder
do hereby declare the nature of iny invention for "IMPROVEMENTS IN APPARATUS.
FOR MAINTAINING A SUPPLY OF BOILING WATER OR STEAM OR OF BOTH and in
what manner the same is to be performed to be particularly described and
ascertained in and by the following statement :-
This invention has for its object improvements in apparatus for maintaining a
supply of boiling water or steam or of both.
.
For many purposes it is desirable to maintain a supply of boiling water which
can be drawn off whenever required at a boiling temperature from a cock or tap
at a distance from the boiler in which the water is boiled-in other cases it is
desirable to maintain a continuous supply of steam for heating purposes or to
maintain a supply both of boiling water and steam. To effect these objects I
employ a steam boiler by preference heated by a burner adapted for burning a
mixture of gas and air. By preference also I use an upright boiler with an arched
inner chamber at the bottom below which the burner is placed and in order to
increase the heating surface of this boiler I place rows of tubes across the chamber.
from one side of the boiler to the other. The rows of tubes I set one above the
other at different levels and preferably. I make them to cross at right angles.
Other forms of steam boiler might however be used instead of a boiler formed in
the above manner. Through the upper part of the boiler I carry upwards a pipe
from a point below the water level and fit it with a cock at its end to allow of
boiling water being at any time drawn off from it. The pipe outside the boiler
I surround by a pipe of larger diameter to which steam can always enter freely
from the boiler so that the water contained in the smaller hot water supply pipe
may always be maintained at or about the boiling point any water drawn off
from it must therefore always be boiling because if the temperature of the water.
gets below the boiling point no water can be drawn off from the cock.
This way of keeping the hot water supply pipe at or about the temperature of
boiling water right up to the cock or tap at which the water is to be drawn off is
applicable whether the boiler be heated by gas or in other ways.
In order that the water in the boiler may always be maintained at a uniform
level I pass a spindle horizontally across the boiler through a stuffing box at one
of its sides. Inside the boiler I provide the spindle with arms to which a float is
connected. Outside the boiler I couple the end of the spindle to the plug of a cock
on the water supply pipe by which water under sufficient pressure is supplied to
the boiler. When the water level in the boiler rises to its proper height the float
rises with it and shuts off the cock. When the water level falls the float descends
with it and opens the cock.

In order to shut off gas from the gas burner whenever the pressure in the boiler.
has been brought up to the point. required I couple the flexible diaphragm of the.

page_text: gas cock used for controlling the supply of gas to the gas burner to a second flexible
diaphragm which closes over the enlarged end of a pipe leading from the lower
part of the boiler. This diaphragm.I cause to be held up by a weighted lever or
otherwise in opposition to the pressure in the boiler but when the pressure in the
boiler overpowers the weighted lever the diaphragm is pressed outwards and closes
the gas supply cock so that whenever there is sufficient pressure in the boiler gas
is turned off from the burner, below it and whenever the pressure again falls in
the boiler the gas cock is again opened. The gas supply cock I provide with a
small bye pass tube with a small regulating cock upon it by which a small quantity
of gas may always be allowed to pass to the burner-I also provide a small gas
jet close to the main burner and supply it with gas from a separate gas supply
pipe so that it may be kept always lighted and ignite the gas at the main burner
50 soon as gas is turned on to it.
I also provide the boiler with a small safety valve loaded to a pressure somewhat
exceeding the pressure required for shutting off the gas from the main gas burner
say to a pressure of about 2 lbs to the inch.
In cases also where a continuous supply of steam is required as for example for
heating purposes.
I also lead off a steam pipe from the upper part of the boiler to wherever it may
be required to use the steam.
Figure 1 of the drawings hereunto annexed shows a vertical section of apparatus
arranged in the manner above described. Figure 2 is a vertical section on a larger
scale of the pressure valve and gas valve--and Figure 3 a cross section of the lower
part of the boiler.

A is the boiler with an arched inner chamber A¹ at the bottom and with tubes B
passing across this chamber-C is the pipe by which boiling water can be drawn off
from the boiler-it is carried up through the top of the boiler and fitted at its end
with a draw off cock. D is the steam pipe enclosing the pipe C to prevent the
water in this pipe from cooling-E is a small pillar or font enclosing the upper
part of the pipe D. Fis the float for regulating the water supply-G the rocking
shaft connecting the float with the plug of the water inlet valvo H-I is the water
supply pipe coming from a cistern at an elevation sufficient to give a pressure of
water greater than the pressure within the boiler-J is the safety valve-K is the
steam pipe passing off to any vessels or apparatus which are to be heated by steam-
Lis the gas valve on a gas supply pipe L' fitted. with a stop cock not shown in the
drawing. M is a flexible diaphragin to which the diaphragm of the gas valve L is
coupled it is fixed across the end of a pipe N coming from the boiler as shown
in Figure 1 and is pressed upwards by a small weighted lever not shown. in the
drawing or by a spring, or other convenient means-0 is a pipe from the gas
valve to the end of. the inlet tube of the burner P which is of an ordinary
construction adapted for burning a mixture of gas and air. Q is a pipe for con-
veying away the burnt gas-R is a small gas jet kept always burning to ensure
the lighting of the gas at the burner P whenever gas may be turned onto it-S is
. a small bye-pass fitted with a cock which can be opened sufficiently to allow
enough gas to pass the valve L when closed to maintain a small flame at the
burner P to keep the water at a boiling temperature. If the apparatus is only
required to maintain a supply of boiling water and not of steam the steain pipe K
may be omitted or if it is required to keep up a supply of steam only the hot water
pipe C and the pipe D which surrounds it may be done away with.
Water heating apparatus formed in the above manner requires no attention as
the water steam and gas are all-regulated by automatic valves and as a small flame
is always kept burning at the small jet R the stop cock on the gas supply pipe L'
can be opened whenever it is desired to heat up, the boiler-As soon as the water
boils and steam is raised say to a pressure of about 2 lbs the diaphragm M is forced
outwards by the pressure and the.. gas valve, L thereby closed, sufficient gas then
passing through the bye-pass S to keep the water. boiling.. Boiling water can at

page_text: any time be drawn off by opening the cock at the end of the pipe C-as the water
is drawn off the float F falls and opens the water supply valve H to admit more
water. When the pressure in the boiler is thereby reduced the diaphragm M is
raised and the gas valve L so opened allowing more gas to pass to the burner P
to again raise the pressure within the boiler.
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. The combination of apparatus substantially in the manner herein before
described for maintaining a supply of boiling water or of steam or of both boiling
water and steam.
2. The means substantially as described for ensuring that all water drawn off
from the hot water supply pipe shall be at a boiling temperature.
3. The combination of apparatus for controlling the supply of gas to the gas
burner by which the boiler is heated.
