Liquids and Solid Food, Applicable also for Cooling Water.
1, James Kerfoot, of 73 Green Lanes, Stoke Newington, in the County of
Middlesex, Licensed Victualler, do hereby declare the nature of this invention to be
as follows:-
This invention relates to the construction of an improved apparatus for mulling or
heating wine, beer and other liquids, and solid food, which apparatus can also be used
when required for supplying iced water.
In carrying out this invention I construct the muller, so that it can be heated on
the hot water circulating system, that is to say, I form it of a double or jacketed
receptacle, the inner portion of which serves to receive the wine or beer to be mulled
or the articles to be heated; a feed cistern placed above the muller serves to supply
a circulating boiler below, the water in which boiler as it becomes hot circulates
therefrom through the space between the inner and outer portions of the muller and
back again into the boiler. Suitable taps are provided for drawing off the mulled
liquid and the hot water.
For heating the boiler I employ a gas apparatus consisting of a tube or chamber
having an inlet and an outlet for the gas, the lower end of the tube extends into the
boiler and forms a chamber containing mercury or equivalent liquid; in the tube is
placed a smaller tube which is adjustable, the lower end of which extends below the
outlet of the gas, a division serving to separate communication between the inlet and
outlet for the gas, which can only take place by the gas first passing through an
opening into the inner tube.
By this arrangement when the water reaches the required temperature the mercury
or equivalent liquid is by the heat expanded so as to cover the open end of the inner
tube and shut off the gas supply, and thereby automatically lower the gas, the said
automatic arrangement again raising the gas on water being drawn from the muller ;
by this means the water compartment of the muller is kept constantly full of hot
water at a practically regular temperature.

page_text: Amongst the advantages to be derived from the use of my improved heating
apparatus or muller may be mentioned the following ;-.
A great saving in gas is effected, it requires no attention, no steam can escape from
it, the muller can be very easily cleaned by reason of its simple construction, the gas
can be always left burning without requiring attention as the water will never reach
above or below a certain temperature, one or more mullers or sausage warmers or the
like can be heated from the same boiler with only the same quantity of gas; the heat
from the gas and the boiler can be utilized for warming the bar or other place in
which the apparatus is to be used, by means of a grating placed above the boiler; the
muller will only occupy a small space and can if required he fixed to a wall in a
similar manner to a gas bracket and it can be used for heating sausages, milk, ten,
coffee, and the like, and for keeping them at a constant temperature. Further the
apparatus when not required for heating or mulling purposes as for example during
the summer months can be used for supplying cold water cooled by means of ice
placed in the inner part of the muller, and which cooled water can be drawn from the
tap thereof as required.
"It will be obvious that the herein described arrangement of gas regulating apparatus
can be adapted for use with existing mullers and the like.

Improvements in and Applicable to Apparatus or Mullers for Heating
Liquids and Solid Food, Applicable also for Cooling Water.
1, JAMES KERFOOT, of 73, Green Lanes, Stoke Newington, in the county of
Middlesex, Licensed Victualler, 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 :-
This invention relates to the construction of an improved apparatus for mulling or
heating wine, beer and other liquids, and solid food, which apparatus can also be
used when required for supplying iced water.
In carrying out this invention I construct the muller or other receiver or cistern so
that it can be heated on the hot water circulating system, that is to say, I form it of a
double or jacketed receptacle the inner portion of which serves to receive the wine or

page_text: beer to be mulled or the articles to be heated; a feed cistern placed above the muller
serves to supply a circulating boiler below, the water in which boiler as it becomes
hot circulates therefrom through the space between the inner and outer portions of
the muller and back again into the boiler. Suitable taps are provided for drawing off
the mulled liquid and the hot water.
For heating the boiler I employ a gas apparatus consisting of a tube or chamber.
having an inlet and an outlet for the gas; the lower end of the tube extends into the
boiler and forms a chamber containing mercury or equivalent liquid; in the tube is
placed a smaller tube which is adjustable, the lower end of which extends below the
outlet of the gas a division serving to prevent direct communication between the
inlet and outlet for the gas which can only take place by the gas first passing through
an opening into the inner tube.
In order to enable my invention to be fully understood I will proceed to describe
how it can be carried into practice by reference to the accompanying drawing in
which figure 1 represents a vertical section partly in elevation of an apparatus for
mulling or heating liquids and solid food (applicable also for cooling water) constructed
according to my invention; figure 2 is a vertical section drawn to a larger scale in
order to clearly illustrate the automatic gas regulating apparatus. Similar letters in
both the figures represent similar parts.
a, b, (figure 1) represent the muller properly so called consisting as shewn of a
double or jacketed receptacle the inner portion or pocket a, of which serves to receive
the wine or beer to be mulled or the food to be heated, whilst the outer portion or
jacket 6, receives the hot water for heating the said liquid or food; c, is the cover of
the inner portion a, of the muller; d, is the feed cistern situated at a suitable level
above the muller and e, is the boiler situated below and kept continually supplied with
water from the feed cistern d, by means of a pipe f; 9 and h, are circulating pipes
through which the water as it becomes hot in the boiler e, circulates to the outer
portion b, of the muller and back again into the boiler as shown by the arrows in
figure 1, the pipe g, extending from the top of the boiler into the portion b, of the
muller whilst the pipe h, passes from near the middle of the boiler and is connected to
a tube i, forming a part of the stand of the muller and communicating with the said
portion b; j, is a flange or plate by which the muller can be fixed to a counter or other
like place where it is required for use; k and I, are the taps for drawing off the mulled
liquid and hot water respectively; a', is a pipe open at its upper end and serving to
allow of the expansion of the water in the boiler, pipes and muller.
m, represents the tube or chamber of my gas apparatus (shewn more clearly in
figure 2) for heating the boiler e; n, is the inlet and o, the outlet for the gas to and
from the tube or chamber m; p, is the chamber containing mercury or equivalent
liquid the said chamber being formed by a continuation of the tube m, extending into
the boiler e, just above the opening of the cold water supply pipe ; q, is the smaller
tube placed within the tube or chamber m, and extending downwards below the gas
outlet o; r, is the division serving to prevent direct communication between the inlet n,
and outlet o, for the gas; this division r, is screw threaded and receives the screw
threaded part of the tube q, by rotating which by its knob s, the position of the tube
can be adjusted; t, is the opening in the inner tube y, the gas entering at n, being
caused by reason of the division r, to enter the tube y, only through this hole, the gas,
when the end of the inner tube q, is not covered by the mercury as hereinafter
described then passing out through the said end and through the lower part of the
tube or chamber m, to the outlet o, and thence through the pipe u, to the burner v;
W is a small hole for allowing a small quantity of gas to pass to the burner when the
end of the tube q, is closed by the mercury so as to prevent the flame from being
completely extinguished.
By this construction of apparatus the boiler and muller are continuously supplied
with water from the cistern d, and the gas being ignited the water in the boiler and
muller will become heated the water circulating through the pipes g and h, as
hereinbefore described the end of the tub y, remaining uncovered by the mercury in
the chamber p, and there being consequently a free supply of gas to the burner until

page_text: the water reaches the required temperature when the mercury or equivalent liquid will
be expanded by the heat so as to cover the open end of the inner tube 7, and shut off
the free supply of gas and thereby automatically lower the gas which can then only
pass to the burner through the small hole w; the said automatic arrangement will
again raise the gas on water being drawn from the muller as this will cause a
quantity of cold water to enter the boiler e, to supply the place of that which has been
drawn off and the mercury will be contracted so as to uncover the end of the tube 9:
by this means the water compartment of the muller is kept constantly full of hot water
at a practically regular temperature.
Amongst the advantages to be derived from the use of my improved heating
apparatus or muller may be mentioned the following:
A great saving in gas is effected, it requires no attention, no steam can escape from
it, the muller can be very easily cleaned by reason of its simple construction, the gas
can be always left burning without requiring attention as the water will never reach
above or below a certain temperature, one or more mullers or sausage warmers or the
like can be heated from the same boiler with only the same gas burner; the heat from
the gas and the boiler can be utilized for warming the bar or other place in which the
apparatus is to be used by means of a grating placed above the boiler; the muller will
only occupy a small space and can if required be fixed to a wall in a similar manner to
a gas bracket and it can be used for heating sausages, milk, tea, coffee and the like, and
for keeping them at a constant temperature. Further the apparatus when not required
for heating or mulling purposes as for example during the summer months can be used
for supplying cold water cooled by means of ice placed in the inner part a, of the
muller and which cooled water can be drawn from the tap 1, as required whilst the
ice-water would be drawn from the tap k; the gas regulating arrangement in this
case would obviously not be required.
It will be obvious that the herein described arrangement of gas regulating apparatus
can be adapted for use with existing mullers and other apparatus for heating liquids.
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 :-
or other
1. The method herein described of automatically supplying "mullers"
apparatus for heating liquids or solid food with hot water by means of a hot water
circulating arrangement substantially as herein before described.
2. The combination with a muller or other heating apparatus of suitable construction,
