We JOHN JAMES ROYLE of 27 and 29 King Street West, Manchester, in the County
of Lancaster, Mechanical Engineer, and JACOB BROWN of 110 Maine Road, Moss
Lane East, Manchester, in the County of Lancaster, Leather Bag Manufacturer, do
hereby declare the nature of our invention to be as follows:-
We take a vessel of any suitable shape or size and place therein a receiver
made of metal or other similar or suitable material but of such a form as to present
the contents to the heating or cooling action of the surrounding medium in thin strata
or layers and so as to be as far as possible surrounded by and to have the greatest
possible surface exposed to such heating or cooling medium.
In this manner we extract say the heat from the surrounding medium which may
consist of boiling water or steam, and impart the same to the liquid placed in the
receiver and which can conveniently be withdrawn therefrom by a suitable tap or
valve.
In performing our invention we find that a convenient arrangement is that of an
inner and outer say cylindrical or oval vessel, the outer vessel being in the form of an
annular or oval casing surrounding the inner vessel and having a thin annular or oval
space between the two. This inner and outer vessel connected together at the bottom
so that the boiling water rises to the same height in both vessels but leaving a space
between the two as aforesaid.
These two vessels being screwed together can be disconnected for cleansing and for
this same purpose the draw-off cock is also arranged with its tail end to screw into
position and thus is capable of removal.

page_text: As a modification of our invention we sometimes arrange the heating or cooling
surface in a deeply corrugated form and to be located at the top of the outer vessel so as
to secure the hottest water therein as the heating medium.
We thus produce an apparatus capable of either heating or cooling milk or other
liquids with great rapidity and which as required, is simply introduced into the space
provided for it and can be instantly withdrawn therefrom through the cock or valve.
In case of cooling the inner vessel may by preference be filled with ice or other cooling
medium.

COMPLETE SPECIFICATION.
Improvements in Apparatus for Rapidly Heating or Cooling
Liquids.
WO JOHN JAMES ROYLE of 27 and 29 King Street West, Manchester, in the
County of Lancaster, Mechanical Engineer, and JACOB BROWN, of 110 Maine Road,
Moss Lane East, Manchester, in the County of Lancaster, Leather Bag Manufacturer,
do hereby declare the nature of our invention and in what manner the same is
to be performed, to be particularly described and ascertained in and by the following
statement:
We take a vessel of any suitable shape or size and place therein a receiver made of
metal or other suitable material but of such a form as to present the contents to the
heating or cooling action of the surrounding medium in thin strata or layers and so as
to be as far as possible surrounded by and to have the greatest possible surface exposed
to such heating or cooling medium.
In this manner we extract the heat from the surrounding medium which may
consist of boiling water steam or other substance and impart the same to the liquid
placed in the receiver and which can conveniently be withdrawn therefrom by a
suitable tap or valve.
In performing our invention we find that a convenient arrangement is that of an
inner and outer say cylindrical or oval vessel, the outer vessel being in the form of an
annular or oval casing surrounding the inner vessel and having a thin annular or oval
space between the two. These inner and outer vessels are connected together at the
bottom so that the boiling water rises to the same height in both vessels but leaving a
space between the two as aforesaid.
These two vessel being screwed together can be disconnected for cleaning and for

page_text: this same purpose the draw off cock is also arranged with its tail end to screw into
position and thus is capable of removal.
As a modification of our invention we sometimes arrange the heating or cooling
surface in a deeply corrugated form and to be located at the top of the outer vessel so
as to secure the hottest water therein as the heating medium.
We thus produce an apparatus capable of either heating or cooling milk or other
liquids with great rapidity and which as required is simply introduced into the space
provided for it and can be instantly withdrawn therefrom through the cock or valve.
In case of cooling the inner vessel may, by preference, be filled with ice or other
cooling medium.
On the accompanying drawings Fig. 1. is a vertical section and Fig. 2. an
exterior elevation of one method of carrying out our invention in the form of a Muller"
for Restaurant purposes and consists of a base or stand A. supporting an outer
cylindrical and annular vessel B. which can be heated or kept hot by a gas burner
underneath or by other convenient means. Into the inside of this vessel another and
smaller vessel C. is inserted and communication is established between the two
vessels through the centre of the wing nut D. and thus a free circulation of water is
permitted between the two vessels when filled with water as illustrated leaving an
annular space E. of relatively small capacity but large extent of heating surface.
We utilize the space so obtained for the rapid heating of all kinds of potable or
other liquids.
In order that such liquids may be introduced with facility we close the top of the
outer vessel B. with a lid F having a funnel G. to receive the liquid. The liquid falls
upon a lid H. and is so directed into the annular space E. J. is a tap for drawing off
the liquid. K. is a tube passing loosely through the hole in the wing nut D. with a
funnel shaped mouth to improve the circulation of the water and assist the heating.
This tube may be omitted if the way through the wing nut bo enlarged.
In order to render the said nut water tight and prevent water from the chambers B.
and C. finding access to the annular space E., some soft packing such as cork, should be
placed under the nut and inner vessel. The water used for heating purposes is
sometimes a convenience and may be drawn off through an additional tap L. provided
for the purpose.
It will thus be seen that the essential feature of our invention for the rapid heating
of potable and other liquids, is the large extent of heating surface forming the annular
space E. and by means of which a small quantity of liquid can be heated with great
rapidity.
As a
"muller" this arrangement dispenses entirely with the necessity
of keeping liquids hot in bulk.
This arrangement is equally effective as a refrigerator by introducing Ice into the
inner vessel C.
By removing the inner vessel C. altogether and closing the passage through the
wing nut D. the apparatus may be used for warming liquids in bulk or alternately as
may be desirable.
This "muller" may be constructed of Copper, Brass or partly of metal and partly of
earthenware. The tap J. is made to unscrew at X for facility of cleaning the inside
of the "muller" which is also easily cleaned by unscrewing the nut D. and removing
the vessel C.
Figs. 3. and 4. illustrate respectively a section and plan of a modified form of this
apparatus, useful more especially for domestic purposes.
In the drawings, C. is the inner vessel surrounded by the outer vessel B. and
leaving an annular space E. which is used for heating purposes. The inner
vessel C. in this case is alone filled with water introduced as hot as possible through
the filling orifice M. The whole is then closed in by the lid N. and enveloped in
some non-conducting material such as a domestic "cosy" and left till wanted, when
the lid N. is removed and the liquid to be heated poured into the annular space E. when
it is rapidly warmed by the heat abstracted from the vessel C. The liquid is drawn
off by the tap J.

page_text: We have found that if this construction be properly surrounded with non-
conducting substance as above it is efficient for a considerable time and forms a cheap
and convenient arrangement for the nursery or sick room or for traveller's use. The
inner vessel C. is easily removed for cleaning purposes.
In Figs. 5. and 6. we illustrate a longitudinal and transverse section of another
modification of the domestic form of our invention in which the heating surface is
in the form of a, corrugated plate O. arranged in an outer vessel P. in such manner
that the outer vessel being filled with water through the filling orifice Q. the
water rises under and inside the corrugations so forming a very large and
effective heating surface. The liquid to be heated is poured on to the corru-
gation and drawn off by the tap S. T. is a lid covering the whole. The water
forming the heating medium may be introduced hot through the orifice Q. and be kept
hot till wanted by means of a "Cosy" or the vessel may in this case be heated by
external means.
We have found the heat is retained more effectively by surrounding the lower part
with felt or other non-conducting substance as indicated by the dotted lines in the
Figures, in addition to the "Cosy."
Having thus particularly described and ascertained the nature of our said invention
together with the best methods with which we are acquainted for carrying the same
into practical effect, we wish it to be understood that we do not confine ourselves to
using water as the heating medium as other liquids or solutions might be employed,
nor to the precise details, relative proportions or dimensions of the apparatus illustrated,
as the same may be considerably varied without departing from the invention but
what we do claim is :-
1st. The improvements in apparatus for rapidly heating or cooling liquids sub-
stantially as and for the purposes described and illustrated on the accompanying
drawings.
2nd. The improved combination and arrangement of an inner and outer vessel
communicating together and affording a space between them for the introduction of
the liquid to be heated or cooled substantially as and for the purposes herein before
described and illustrated on the accompanying drawing.
3rd. In apparatus for rapidly heating or cooling liquids the employment of a
separate inner and outer vessel arranged and operating substantially as herein before
described and illustrated on the accompanying drawing.
4th. The improved arrangement of apparatus substantially as and for the purposes
herein described and illustrated in Figs. 5 and 6 of the accompanying drawing.
