Bridge, in the City of London, Engineer, and Willoughby Digby Marsh,
of 11, James Street, in the County of Middlesex, Captain in Her
Majesty's Royal Engineers, for the Invention of "IMPROVEMENTS IN.

Sealed the 11th December 1860, and dated the 16th June 1860.
PROVISIONAL SPECIFICATION left by the said Edward Deane and
Willoughby Digby Marsh at the Office of the Commissioners of Patents,.
with their Petition, on the 16th June 1860.
We, EDWARD DEANE, of 1, Arthur Street East, London Bridge, in the City
of London, Engineer, and WILLOUGHBY DIGBY MARSH, of 11, James Street,
in the County of Middlesex, Captain in Her Majesty's Royal Engineers, do
hereby declare the nature of the said Invention for "IMPROVEMENTS IN KITCHEN
RANGES OR APPARATUS FOR COOKING," to be as follows:-
This Invention consists in constructing kitchen ranges with two distinct fire-
grates, which may be either one large and one small grate, or both grates of
equal size, with a boiler or boilers between them (forming one side of each
grate), which boiler or boilers may also form the back or backs of the grate
or grates, and even extend on the other side of the grate, one of which boilers
may be for "circulation" of hot water or steam, and the other for producing hot
water for culinary and other purposes; or the one boiler which is interposed.
between the two grates may be made so as to be used as occasion may require,
either for circulation or otherwise, provision being made by suitable pipes.
and taps for that purpose.

by the said Edward Deane and Willoughby Digby Marsh in the Great
Seal Patent Office on the 15th December 1860.
TO ALL TO WHOM THESE PRESENTS SHALL COME, we, EDWARD
DEANE, of No. 1, Arthur Street East, London Bridge, in the City of London,
Engineer, and WILLOUGHBY DIGBY MARSH, of 11, James Street, in the
County of Middlesex, Capt. R.E., send greeting.
WHEREAS Her most Excellent Majesty Queen Victoria, by Her Letters
Patent, bearing date the Sixteenth day of June, in the year of our Lord
One thousand eight hundred and sixty, in the twenty-third year of Her
reign, did, for Herself, Her heirs and successors, give and grant unto us, the
said Edward Deane and Willoughby Digby Marsh, Her special licence that we,
the said Edward Deane and Willoughby Digby Marsh, our executors, adminis-
trators, and assigns, or such others as we, the said Edward Deane and
Willoughby Digby Marsh, our executors, administrators, and assigns, should at
any time agree with, and no others, from time to time and at all times there-
after during the term therein expressed, should and lawfully might make, use,
exercise, and vend, within the United Kingdom of Great Britain and Ireland,
the Channel Islands, and Isle of Man, an Invention for "IMPROVEMENTS IN
KITCHEN RANGES OR APPARATUS FOR COOKING," upon the condition (amongst
others) that we, the said Edward Deane and Willoughby Digby Marsh,
our executors or administrators, by an instrument in writing under
their, or one of their hands and seals, should particularly describe and ascer-
tain the nature of the said Invention, and in what manner the same was to be
performed, and cause the same to be filed in the Great Seal Patent Office
within six calendar months next and immediately after the date of the said
Letters Patent.
or
NOW KNOW YE, that we, the said Edward Deane and Willoughby Digby
Marsh, do hereby declare the nature of the said Invention, and in what manner
the same is to be performed, to be particularly described and ascertained in
and by the following statement thereof :-
This Invention has for its object the construction of a kitchen range or
apparatus for cooking which shall be economical and efficient, whether the
same be required to be used as the means of effecting the cooking operations
and other uses demanded for a large or for a small number of persons, the
same range being thus adapted to be used with economy by a small family,
and yet, when circumstances may require it, being equally well suited to be used
for cooking for a large number of persons, and the very peculiarities of this

page_text: range rendering it more efficient for all the purposes for which ranges are
required, all which we effect without resorting to the aid of winding cheeks or
other cheeks. To carry out this, we make a kitchen range with two distinct
fire-grates, which we prefer to be different in width, that is, one larger than the
other, and these we separate and part from each other by interposing between
them a boiler or boilers or a part of a boiler or parts of boilers, so that the
fronts of these grates are separated by a solid end of the said boiler or boilers
(it being recommended that such end should be of no very great width, in order
that when both grates are used at one and the same time, the heat from the
two shall have, as far as may be, the effect the same width of grate would bave,
supposing it to be a grate of one uninterupted surface). This boiler runs, or
these boilers run on at right angles to the part interposed between the two
grates as aforesaid at the backs of the said grates and partly at the backs of two
ovens (we prefer two, though one may be adopted if thought suitable, a part
of the boiler occupying its place or otherwise); these two ovens being on the
sides of the fire-grates, which are not formed by the projecting part of the
boiler aforesaid, such ovens having flues or hot-air passages encompassing
them every way except at the front parts where the doors are situate, the
sinoke, heat, and products of combustion passing through the mouths of those
flues situate at the sides of the grates, and also through the openings at the
backs of the grates over the boiler or boilers, descending to the level of the
ash-pits, where there is an outlet for smoke into the chimney, the range
being, of course, so "set" or constructed that the smoke may be prevented
from ascending from the top of the fire by closing the same by sliding hot
plates or otherwise (which is a certain cure for smoky chimneys), and a door
or sliding plate (which may be wholly removed when necessary), being
provided for closing the front also of that grate which may not be in use at
any particular time. When two or more boilers are used, one or more may
be for heating water for ordinary kitchen or domestic use, and the other may
be for "circulation," and may have hot-water pipes to convey the hot water
to heat halls, passages, rooms, baths, conservatories, greenhouses, or other
places.
The Drawing accompanying this Specification is illustrative merely, and
will be understood by inspecting the same. And it may be here remarked
that although not specifically mentioned herein nor shewn by the Drawing, yet
it is evident that most of the adjuncts and appliances of known kitchen ranges
may be used with this range.
Having now particularly described and ascertained the nature of our said
Invention, and in what manner the same is to be performed, we declare that we

page_text: .claim, the improvements in kitchen ranges, consisting in making the same
.with two fire-grates, having a boiler or part or parts of a boiler or boilers
between them; and also the general arrangements of the said kitchen ranges
,as regards the ovens and other parts thereof, in combination with the above.
In witness whereof, I, the said Edward Deane, have hereunto set my
hand and seal, this Fifteenth day of December, in the year of our
Lord One thousand eight hundred and sixty.
Signed and sealed in my presence,
F. W. CAMPIN, Patent Agent,
156, Strand.
EDWARD DEANE. (L.S.)
