PROVISIONAL SPECIFICATION.
An Improved Apparatus for Giving a Constant Supply of Boiling
Water for use in Bars and the like.
I, JOHN BOULTING, of 6 Upper Marylebone Street, in the Parish of Marylebone,
in the County of London, Engineer do hereby declare the nature of this invention
to be as follows:-
My invention relates to an improved apparatus for giving a constant supply of
boiling water for use in bars and the like. The apparatus for generating the
boiling water may be fixed under the counter of the bar or at any other convenient
distance therefrom, the draw-off tap being preferably fixed to an ornamental metal
pillar adapted to be fixed to the counter. The water may be heated either by gas
or by steam or by both in combination.
When gas is used as the heating medium, I take a boiler capable of holding say
one gallon of water. This boiler is mounted in a suitable case over an ordinary
atmospheric gas burner, and it is connected with an automatic self-feeding supply
The boiler may be at
tank by means of a siphon pipe in the well-known manner.
any convenient distance from the draw-off tap. As near to the draw-off tap as is
convenient I place another boiler heated by an atmospheric gas burner but only
capable of holding say about one third the quantity of water, as the first mentioned
boiler. This second boiler is connected to the first boiler by a suitable pipe, and
from the top of the said boiler a pipe leads to the draw-off tap, and it is continued
upwards and bent downwards to form a siphon and is then carried to a waste or
sink, the end of the pipe being left open as it also serves the purpose of the safety
steam pipe of the apparatus. The use of the second or smaller boiler is to ensure
the water that is drawn off being at boiling point, and it may be dispensed with in
case the main boiler is in close proximity to the draw-off tap. By using this second
boiler and having a second-draw-off tap connected directly to the main boiler both
hot and boiling water may be obtained, the first being drawn direct from the main
boiler and the latter from the second or boiling boiler, in which case the water is
only heated in the first boiler to the point desired.
When steam is used as the heating medium the main boiler is fitted with a steam
coil through which steam at about two to six pound pressure is forced from a con-
venient generating boiler. In this case I prefer to make the ornamental stand
carrying the draw-off tap as the second boiler, in which case it is fitted with a steam
coil supplied from the same source as the steam coil in the main boiler. The second
boiler is connected with the main boiler by two pipes providing for the flow and
return of the heated water from and to the main boiler. To bring the water in the
second boiler up to boiling point steam is admitted into the coil within the boiler by
means of a suitable valve, and as the second boiler is of a smaller capacity than the
main boiler the water therein is easily raised from the temperature at which it is
passed out of the main boiler, up to boiling point. The steam coil in the second
boiler is fitted with the usual over-flow pipe open at its end and adapted to act as a
safety steam pipe.

An Improved Apparatus for Giving a Constant Supply of Boiling
Water for use in Bars and the like.
1. JOHN BOULTING, of 6 Upper Marylebone Street, in the Parish of Marylebone,
in the County of London, Engineer, 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 :-
My invention relates to an improved apparatus for giving a constant supply of
boiling water for use in bars and the like. The apparatus for generating the boiling
water may be fixed under the counter of the bar or at any convenient distance
therefrom, the draw-off tap being fixed to an ornamental metal pillar adapted to be
fixed to the counter. The water may be heated either by gas or by steam or by
both in combination.
When gas is used as the heating medium, I take a boiler capable of holding say
one gallon of water. This boiler is mounted in a suitable case over an ordinary
atmospheric gas burner, and it is connected with an automatic self-feeding supply
tank by means of a pipe, preferably having a siphon in it in the ordinary manner.
This boiler may be at any convenient distance from the draw-off tap. As near to
the draw-off tap as is convenient I place another boiler heated by an atmospheric
gas burner but only capable of holding say about one third the quantity of water as
the first mentioned boiler. This second boiler is connected to the first boiler by a
suitable pipe and from the top of the said boiler a pipe leads to the draw-off tap,
and it is continued upwards and bent downwards to form a siphon, and is then
carried to a waste or sink, the end of the pipe being left open as it also serves the
purpose of the safety steam pipe of the apparatus. The use of the second or
smaller boiler is to ensure the water that is drawn off being at boiling point, and it.
may be dispensed with in case the main boiler is in close proximity to the draw-off
tap.
When steam is used as the heating medium both boilers are fitted with a steam
coil through which steam at about two to six pound pressure is passed from a con-
venient generating boiler. To bring the water in the second boiler up to boiling
point steam is admitted into the coil within the boiler by means of a suitable
valve, and as the said boiler is of a smaller capacity than the main boiler, the
water therein is easily raised from the temperature at which it is passed out of the
main boiler, up to boiling point.
In order that my invention may be fully understood I will more particularly
describe it making reference to the accompanying drawing, in which :-
Figure 1 is a diagrammatic view showing the construction of my apparatus when
gas is used as the heating medium, and
Figure 2 is a similar view of a modification of my apparatus adapted to use either
gas or steam, or both in combination, as the heating medium.
In both views similar parts are marked with like letters of reference.
Referring to Figure 1. A designates the main boiler holding say one gallon of
water and mounted in a suitable cast iron case to which is attached an atmospheric
gas burner X. B designates the second boiler constructed in any suitable form and
holding say three pints of water. This boiler is also fitted with an atmospheric gas
burner X and it is connected with the boiler A by a pipe "a." C designates an
ornamental metal pillar adapted to be fixed to the counter or shelf. D designates
the pipe leading from top of the boiler B and extending up into the pillar C. To
this pipe D is fixed the draw-off tap E. To the top of the pipe D is attached an
overflow pipe which is carried to a waste or sink, or any vessel where the overflow
water may be used for washing up, or other purposes. The end of this pipe is open
as it acts as the safety steam pipe of the apparatus. G designates a self-filling
supply cistern of the ordinary type, which may be fixed at any convenient distance

page_text: rom the apparatus. H designates the pipe from cistern G to the main boiler A in
which a siphon may be made if desired. The atmospheric gas burners X, X, are
referably fitted with pilot lights, and the supply pipes are fitted with suitable taps
r valves for regulating the supply of gas.
Referring to Figure 2. The boiler A which is capable of holding say from 6
o 10 gallons is fitted with a steam coil J within it, and the boiler B is also fitted
with a steam coil K which is perforated. The steam coil J is connected to the main
steam pipe L by a pipe "j," and it also has a pipe "j" to carry off the condensed
The
steam. The pipe "" is fitted with any suitable form of regulating valve.
perforated steam coil K is connected with the main steam pipe L by means of a
pipe "k" preferably passing up through the pipe D and down outside it but within
the case C, the said pipe being fitted with any suitable form of regulating valve.
As a modification the pipe "k" from the perforated coil K may be lead to the main
steam pipe L direct. In this apparatus it will be seen that both boilers may be
entirely heated either by steam, or by gas, or partly by steam and partly by gas.
I wish it to be particularly understood that I do not limit myself to the precise
details of construction hereinbefore described and illustrated by the accompanying
drawing but that I hold myself at liberty to make such changes and alterations as
fairly fall within the spirit and scope of my invention.
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. The combination of parts hereinbefore described and illustrated by the
accompanying drawing, constituting an improved apparatus for giving a constant
supply of boiling water.
2. In an apparatus for giving a constant supply of boiling water, the combination
of two boilers of unequal capacity communicating with each other and each heated
by an atmospheric gas burner, the larger of the two boilers being in communication
with a supply cistern and the smaller in communication with the draw-off tap, as set
forth.
3. In an apparatus for giving a constant supply of boiling water, the combination
of two boilers of unequal capacity communicating with each other and each fitted
with an atmospheric gas burner, the larger of the two boilers being connected
with a supply cistern and having within it a steam heating coil connected with a
5 steam generator, and the smaller boiler being connected with the draw-off tap and
having within it a perforated steam heating coil connected with the steam generator,
as set forth.
