Year: 1872

page_text: LETTERS PATENT to Henry Edward Mines, of Cheltenham, in the
County of Gloucester, Ironmonger, for the Invention of "IMPROVE-
MENTS IN KITCHEN RANGES."
Sealed the 7th March 1873, and dated the 13th September 1872.
PROVISIONAL SPECIFICATION left by the said Henry Edward Mines
at the Office of the Commissioners of Patents, with his Petition, on
the 18th September 1872.
I, HENRY EDWARD MINES, of Cheltenham, in the County of Glou-
cester, Ironmonger, do hereby declare the nature of my said Invention
for "IMPROVEMENTS IN KITCHEN RANGES," to be as follows:-
This Invention relates to the supplying of the fires of all close ranges
with heated air, and consists, according to one arrangement, in the
employment of a double door or two doors situate in front of the fire, the
outside door being made on a frame standing about two inches from the
inner door, and the sides and bottom are closed, so that the air is com-
pelled to pass between the two doors through an aperture under the
bottom of the grate into the fire, and becomes heated in its passage. Or
the fire-hole may be lined will hollow iron checks and back, and the air
for supporting combustion is caused to pass through holes in the front of

page_text: the range and through the cheeks and back, and is admitted into the fire
through an opening made at or near the bottom of the back. Or an
opening may be formed in the brick or iron back at the back of the hot
plate and the air be caused to pass down through a small chamber
behind the brick or iron back of the fire-hole into the fire, the front in 5
both the latter modifications being closed.
SPECIFICATION in pursuance of the conditions of the Letters Patent,
filed by the said Henry Edward Mines in the Great Seal Patent
Office on the 12th March 1873.
TO ALL TO WHOM THESE PRESENTS SHALL COME, I, HENRY ]
EDWARD MINES, of Cheltenham, in the County of Gloucester, Iron-
monger, send greeting.
WHEREAS Her most Excellent Majesty Queen Victoria, by Her
Letters Patent, bearing date the Thirteenth day of September, in the
year of our Lord One thousand eight hundred and seventy-two, in the
thirty-sixth year of Her reign, did, for Herself, Her heirs and successors,
give and grant unto me, the said Henry Edward Mines, Her special
license that I, the said Henry Edward Mines, my executors, adminis-
trators, and assigns, or such others as I, the said Henry Edward Mines,
my executors, administrators, or assigns, should at any time agree with,
and no others, from time to time and at all times thereafter 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," upon the condition (amongst others) that I, the said
Henry Edward Mines, my executors or administrators, by an instrument
in writing under my hand and seal, should particularly describe and
ascertain 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.
NOW KNOW YE, that I, the said Henry Edward Mines, do hereby
declare the nature of my said Invention, and in what manner the same
is to be performed, to be particularly described and ascertained in and
by the following statement, reference being had to the accompanying

page_text: Drawings, and to the letters and figures marked thereon, that is to
say:
My said Invention relates to the supplying of the fires of all close
ranges with heated air, and consists, according to one arrangement, as
illustrated in vertical section in Figure 1 of the annexed Sheet of
Drawings, in the employment of a double or hollow door or two separate
doors a, a, situate in front of the fire b, the outside door a¹ being made
on a frame c standing about two inches from the inner door a, and the
sides and bottom are closed, so that the air is compelled to pass, as
shewn by the arrows, between the two doors through an aperture d
under the bottom e of the grate into the fire, and becomes heated in its
passage. Or the fire-hole may be lined with hollow iron cheeks a and
hollow back at (as shewn in Figures 2 and 3), and the air for supporting
combustion is caused to pass through holes b, b, in the front of the range
and through the hollow cheeks and back, and is admitted into the fire
through an opening c made at or near the bottom of the back. Or an
opening a, as shewn in Figure 4, may be formed in the brick or iron
back at the back of the hot plate b, and the air be caused to pass down
through a small chamber or passage o behind the brick or iron back of
the fire-hole, up through the bottom grate d, into the fire, as shewn by
the arrows, the front in all cases being closed.
Having now described and particularly ascertained the nature of my
said Invention, and the manner in which the same is or may be used or
carried into effect, I would observe in conclusion that what I consider
to be novel and original and therefore claim as the Invention secured to
me by the herein-before in part recited Letters Patent is, the peculiar
arrangements for admitting and heating the air for supporting com-
bustion in the fires of close kitchen ranges, as herein-before described
and illustrated by the Drawings hereunto annexed.
I
In witness whereof, I, the said Henry Edward Mines, have to this
my Specification set my hand and seal, this Tenth day of March
One thousand eight hundred and seventy-three.
