THOMAS ROSETHORN, of 72, Waterloo Road, Cheetham, Manchester, in the
County of Lancaster, Insurance Broker, do hereby declare the nature of this
invention to be as follows:-
-
The object of this invention is that of providing an improved method of
quickly heating liquids such as porter, beer, wines, spirits, or any other kind
of liquids.
To accomplish this end I make use of a cylinder or other vessel of copper or
other suitable material, of such size as may be necessary, in which I insert one
or more tubular coils made of block-tin or of such other material as may be
best adapted for the purpose in view, these tubular coils being constructed of
such dimensions as may be required.
Each tubular coil is carried through the said cylinder or other vessel, at the
top and bottom, or at such other positions as may be deemed requisite. A tun-
dish with lid, or other contrivance is affixed to the top of the tubular coil, and
a drain tap is supplied to the bottom thereof-the top for filling in the liquid
to be heated, and the bottom for discharging its contents and controlling the
flow of the liquid therein when sufficiently heated.
In connection with the said cylinder or other vessel, a tundish with lid, at
the top and a drain tap at the bottom are provided.
The cylinder or other vessel I fill with hot water, or I may make use of
steam, or I may employ other efficient means for generating heat therein. Pre-
ferably I use gas heat to boil the water, and consequently I fix suitable gas
burners underneath, or on such other portion of the cylinder or other vessel,
as will attain the object I wish to secure thereby, vizt., that of keeping the water
contained therein constantly at boiling point; at he same time I make provision
to maintain the water at such a height as will always surround and cover the
coil or coils fixed therein, as previously described.
I then pour the liquid to be heated into the coil or coils as soon as may be
after being drawn off or pumped up from the cask or other receptacle in which
it is contained, and when this is done I draw off the liquid,-which by the novel
method herein described, becomes heated almost instantaneously,-from the coil
or coils at the tap provided for the purpose.

page_text: An Improved Means for Heating Liquids.
I, THOMAS ROSETHORN, of 72, Waterloo Road, Cheetham, Manchester, in the
County of Lancaster, Commission Agent, 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 apparatus for instantaneously or quickly heating
liquids and consists of a simple arrangement of parts which ensures great
efficiency of the apparatus, cleanliness and enables it to be constructed at a low
first cost.
For this purpose I construct a light metal cylinder or other shaped receptacle
which may be ornamented to any extent or be of plain metal and is capable of
being filled with water through a cup or funnel disposed near the top and
emptied of water through a tap at the bottom. Disposed inside this vessel so
as to be normally immersed in the hot water is a continuous coil of pipe which
is impervious to the water and connected at its upper end to a cup or funnel
disposed underneath the central cover of the heater and at its lower end to a
tap from which any liquid it contains may be drawn.
The water is heated by means of a gas or other burner disposed immediately
under the bottom of the water chamber.
It is of importance in order to secure the most efficient action in this appa-
ratus that the continuous coil or worm should be constructed of a metal or other
material which will absorb and transmit heat very quickly; and I have dis-
covered that pure block tin is peculiarly suitable in this respect, as also on
account of its non-corrosive nature and consequent cleanliness."
This apparatus is especially suitable for use in public-house and hotel bars,
as the water surrounding the tube can be used for mixing with spirits for making
toddy and the like; while in order to heat beer, wines or other liquids all that
is necessary is to remove the cover, pour the liquid to be heated into the cup
or funnel whence it runs into the coil or worm and can be drawn off through
the tap.
In order that my invention may be fully understood and ascertained, I append
drawings in which:-
Fig. 1, is an elevation of an apparatus according to my invention.
Fig. 2, is a vertical section of the water vessel shewing the coil or worn in
elevation.
A indicates the cylinder which may be made of any suitable metal, and
ornamented as desired. It has a bottom a disposed at a sufficient height
above the base of the cylinder to enable a ring or other gas burner B supplied
by a pipe b to be inserted beneath it, in such manner that the flame or flames
from the gas burner transmit their heat through the bottom a to the water
contained in the cylinder A. A cup or funnel a arranged on the exterior of
the cylinder communicates directly with the interior of the cylinder and through
it any desired quantity of water can be introduced. When required the water
can be drawn off through the tap a².
"
At the top of the cylinder is situated a cup or tundish" C which is normally
closed by a cover c. This cup has the form of an inverted truncated cone and
its lower end c is open to the upper end of the helical pipe or coil D which is
thence continued downwards and out through the side of the cylinder at the
point so as to communicate with the cock d. By this means cold liquid
poured into the cup or "tundish" C flows down through the heated pipe D and

page_text: when drawn out of the tap is sufficiently heated for drinking purposes. This
occupies but one or two seconds and by leaving the liquid in the coil a few
seconds longer it may be made to approach boiling heat.
I have shewn my heater as of a plain cylindrical form and containing a simple
helically-shaped tube but I would have it understood that heaters according to
my invention may be of any suitable design and the coil contained therein be
of any suitable shape provided it secures a flow of the liquid to be heated
through the body of hot water from the cup C to the tap d
Any other method of heating the water may be employed in the place of gas.
A special feature of my invention is that all the taps employed are screwed
into the vessel; they can thus be easily removed for cleaning and other
purposes.
Having now particularly described and ascertained the nature of my said
invention, and in what manner the same is to be performed, declare that what
I claim is:
1. An apparatus for heating liquids constructed and operating substantially
in the manner and for the purpose described and shewn with reference to the
accompanying drawings.
2. An apparatus for heating liquids in which the liquid to be heated is
passed through a coil or tube which is normally immersed in hot water and in
which the liquid to be heated is poured into a cup at the top of the vessel and
drawn out through a tap near its lower end substantially as described and shewn.
3. In apparatus for heating liquids, the combination of a water vessel A
having a bottom a a heating device B, a water cup, a water tap ², a cup C,
a coil D, and a tap d, all arranged and capable of being operated substantially
in the manner described and shewn.
