AN IMPROVED HEATING AND. COOKING APPARATUS
Year: 1874

page_text: LETTERS PATENT to Edward Knowles Heaps, of Burton Salmon, and
William Wheatley, of Brotherton, both in the County of York, for
PROVISIONAL SPECIFICATION left by the said Edward Knowles
Heaps and William Wheatley at the Office of the Commissioners of
Patents, with their Petition, on the 1st September 1874.
WC, EDWARD KNOWLES HEAPS, of Burton Salmon, and WILLIAM
WHEATLEY, of Brotherton, both in the County of York, do hereby,
declare the nature of the said Invention for "AN IMPROVED HEATING AND.
COOKING APPARATUS," to be as follows:-
'
Our Invention consists of a heating and cooking apparatus of a
simple construction whereby water is heated very quickly and at a very
small cost. The hot water may be carried through pipes to places that
are required to be heated or for cooking purposes, and is as hercafter
described.

page_text: For obtaining the required heat we, by preference, employ gas, mineral
or other oils or spirits.
The apparatus consists,―
Firstly. Of a metal boiler through which in a vertical direction are
passed one or more chimneys or flues. Under each chimney or flue
preparation is made for a light from gas, oil, or spirit. In order to cause
the water to be heated quickly we provide one or more tubes which
connect the upper and lower part of the boiler through which the water
is allowed to circulate freely. The boiler is kept quite full of water,
and as the water gets heated it rises into a circulating tank from
which the supply water is obtained. When required other circulating
tubes may be placed transversely in the chimney or chimneys.
Secondly. When preferred, a central chimney may be provided within
the boiler, consisting of a coiled tube of copper or other suitable metal,
or the coiled tube forming the chimney may be used separately from
the boiler, and so arranged that water is continually circulating
through it.
SPECIFICATION in pursuance of the conditions of the Letters Patent,
filed by the said Edward Knowles Heaps and William Wheatley in
the Great Seal Patent Office on the 30th January 1875.
TO ALL TO WHOM THESE PRESENTS SHALL COME, we, EDWARD
KNOWLES HEAPS, of Burton Salmon, and WILLIAM WHEATLEY, of
Brotherton, both in the County of York, send grecting.
WHEREAS Her most Excellent Majesty Queen Victoria, by Her
Letters Patent, bearing date the First day of September, in the year of
our Lord One thousand eight hundred and seventy-four, in the thirty-
eighth year of Her reign, did, for Herself, Her heirs and successors,
give and grant unto us, the said Edward Knowles Heaps and William
Wheatley, Her special licence that we, the said Edward Knowles Heaps
and William Wheatley, our executors, administrators, and assigns, or
such others as we, the said Edward Knowles Heaps and William
Wheatley, our executors, administrators, and assigns, should at any time
agree with, and no others, from time to time and at all times thereafter

through it.
In order that our Invention may be more completely understood
reference is given to the accompanying Sheet of Drawings.
In Figs. 1 and 2, a is a metal tube through which in a vertical direc-
tion one or more chimneys or flues are passed. Under each chimney
or flue 6 preparation is made for a light from oil or spirits, as shewn at c,
or when preferred gas lights may be employed. In order to prevent the
heat passing off too quickly through the chimney or flue & we check it,
as shewn at d, and convey the gases off through the small tubes e.
Tubes and are connected with a circulating tank by means of
suitable pipes or tubes. The boiler is kept quite full of water, and as
the water becomes heated it rises into the circulating tank, from whence
the supply water is obtained. This arrangement of boiler is applicable
for heating greenhouses, offices, and other places, also for supplying lot
water to baths, and other purposes. When the air in the apartment in
which this boiler is placed is required to be moistened wo provide the
cup in which we place water; this becomes heated by the waste heat
passing from the chimneys or flues & and causes the water to evaporate
whereby the atmosphere in the room is not only heated but moistened.
:
When preferred, a central chimney or flue may be provided within the
boiler, as shewn at Figs. 3 and 4, consisting of a coiled tube i which
may be made of copper or other suitable metal. This is applicable for
the same purposes as the boiler, shewn in Figs. 1. and 2, and its other
parts may also be arranged in the same manner. The coiled tube i may
be used separately from the boiler and so arranged that water is con-
tinually circulating through it, being also provided with a light similar
to those herein-before described for heating purposes.
Figs. 5 and 6 represent a boiler with a circulating tube ; placed
transversely in the tube or chimney; when required other circulating
tubes may be placed therein. This boiler is used in a similar manner, and
for the same or like purposes as those herein-before described.
Figs. 7, 8, and 9, represent respectively a side elevation, end elevation,
and plan of the boiler we chiefly use for cooking purposes. It is shewn
with two chimneys or flues k passing direct through the boiler, although
in some cases only one chimney or flue is required. We make provision
:

page_text: to supply the boiler with water, by preference at 1, through which is
passed water when required. It is not necessary that this boiler should
be kept full. We provide the tap m through which hot water may be
drawn at pleasure.
When this boiler is required for cooking purposes we provide an oven,
side elevations of which are shewn at Figs. 10 and 11, and a plan at
Fig. 12. In connection and above the oven is provided a steamer n
for boiling or steaming articles of food. The mode of applying the
boiler to the oven and steamer n is shewn at Fig. 13, which shews
the position in which the oven and steamer n are placed for cooking
purposes. The steam is conveyed from the boiler to the steaming appa-
ratus, by preference through a metallic tube o, and a recess p is
provided for the reception of the condensed steam, or of any other
matter from the article in process of cooking. This is to prevent the
water in the boiler from being fouled so that it may be used for other
purposes. We pass the flues q through the oven for heating purposes.
These are so connected to the chimneys or flues k that the heat and
waste gases from the chimneys or flues k pass up them. In order to
retard the heat on its way through the chimneys or flues k and to accu-
mulate as much heat as possible under the oven, we provide the recess r
at the bottom thereof into which the heat must pass before going up the
smaller flues q in the oven.
"Articles of food may also be cooked upon the boiler over the chimneys
or flues k by the heat arising from the light or lights. For heating the
water and cooking purposes we provide suitable light from gas, or when
preferred, the lamps 8, shown at Figs. 14, 15, and 16, for burning oils
and spirits. It will be seen at Fig. 13, that the upper part t of the
lamps & forms the stand for the boiler, and that when the boiler is in
position the top parts t of the lamps 8 fit within the flues or chimneys k,
and that the bottom end of the chimneys or flues k are provided with
a water casing u which forms part of the boiler; this has the effect
of preventing the oil or spirit becoming too much heated. When pre-
ferred, the lamp itself may be enclosed within a space containing cold
water.
.

page_text: When necessary, instead of constructing our boiler to extend the full
length or height of the chimney or flue, we make it much shallower, as
shewn at o, Fig. 17, of which Fig. 18 is a plan. In this arrangement
of the boiler the chimney or flue w is extended some distance beyond or
above, and surrounded by pipes x in a vertical direction, as shewn. The
steam arising from the boiler escapes through the holes y in the top, a
light being placed within or at the bottom of the chimney or flue w, as
herein-before described. The chimney or flue to becomes heated, also
the water in the boiler and the vertical pipes x. At the same time air
begins to pass up the pipes into the room or apartment carrying with it
a portion of the steam from the water in the boiler, supplying the room
or apartment thereby with moisture as well as heat.
Our Invention may also be employed for incubation. In this case a
similar boiler to that shewn at Figs. 7, 8, and 9, may be employed. We
have shewn the mode of applying it at Fig. 19, of which Fig. 20 is a
plan. The box or apparatus is shewn at 1 through which the flues 2
pass. These flues 2 are in connection with those in the boiler, and through
them is conveyed the waste heat from the boiler, flues, or chimneys.
Inside the box 1 is placed sand, as shewn at 3, lamps being employed
at the bottom of the boiler, flues, or chimneys, as herein-before
imentioned. The water in the boiler becomes heated, also the flues 2
passing through the box 1 from which heat is given off to the sand. In
the sand the eggs are placed for the purpose of hatching. Care must be
taken to keep up an even temperature which may be done by regulating
the amount of light.
We wish it to be understood that foot warmers heated by hot water
for warming railway carriages and other places may be provided with
similar chimneys and flues to those described in the accompanying
Sheet of Drawings, and the water heated in a similar manner. Tea
urns may also be provided with chimneys or flues similar to those
described in the accompanying Sheet of Drawings, and heated in a
similar manner.
Having now fully described the nature of our Invention, we would
state in conclusion that we do not claim the oven and steamer shown at
Figs. 10, 11, 12, and 13, for cooking purposes, nor the box 1, shewn at
Fig. 19, for the purpose of incubation when taken separately and alone.
Neither do we limit ourselves to the exact details of the various parts

page_text: we have explained and shewn, as the same may be varied or modified
without in any way departing from the nature of our Invention, but
what we do claim is,―
Firstly. The arrangement, construction, and application, of a metal
chimney or flue, in such a manner as to form the interior of a boiler or
water heater, the water of which boiler or water heater being round the
light, substantially as and for the purposes herein set forth.
Secondly. The various arrangements and constructions of the flues
through the interiors of the boilers or water heaters to be heated by gas,
spirits, or oil, substantially as and for the purposes herein set forth.
In witness whereof, we, the said Edward Knowles Heaps and
William Wheatley, have hereunto set our hands and seals, this
Twenty-fifth day of January, in the year of our Lord One thousand
eight hundred and seventy-five.
