Year: 1857

page_text: LETTERS PATENT to John Bradley, of Huddersfield, in the County of
York, Ironmonger, for the Invention of "IMPROVEMENTS IN OVENS APPLI-
CABLE FOR BAKING BREAD AND PASTRY, ROASTING OR COOKING MEATS, AND
BIMILAR PURPOSES."
Sealed the 15th June 1858, and dated the 15th December 1857.
PROVISIONAL SPECIFICATION left by the said John Bradley at the
Office of the Commissioners of Patents, with his Petition, on the
15th December 1857.
I, JOHN BRADLEY, of Huddersfield, in the County of York, Ironmonger, do
hereby declare the nature of the said Invention for "IMPROVEMENTS IN OVENS.
APPLICABLE FOR BAKING BREAD AND PASTRY, ROASTING OR COOKING MEATS, AND
SIMILAR PURPOSES," to be as follows:-
This Invention relates to domestic or kitchen ovens, which are usually set or.
fixed adjoining the kitchen fire-grate, and when used for baking, &c., fire
from the grate is pushed underneath to heat the same.
My improvements consist in dispensing with fire underneath the oven by
the employment of a pipe or flue of metal or other suitable material applied
to the back or other convenient part of the fire-grate, having an opening
thereto and communicating with the flues of the oven, which are arranged so
that the heated air or gases will be conducted from the fire to the top,
sides, bottom, and back of the oven, and thence to the chimney, whereby I
obtain a more equal distribution of heat or temperature with less care or
attention, and effect a saving of fuel.

by the said John Bradley in the Great Seal Patent Office on the 15th
June 1858.
TO ALL TO WHOM THESE PRESENTS SHALL COME, 1, JOHN
BRADLEY, of Huddersfield, in the County of York, Ironmonger, send greeting.
WHEREAS Her most Excellent Majesty Queen Victoria, by Her Letters
Patent, bearing date the Fifteenth day of December, in the year of our
Lord One thousand eight hundred and fifty-seven, in the twenty-first year of
Her reigu, did, for Herself, Her heirs and successors, give and grant unto
me, the said John Bradley, Her special licence that I, the said John Bradley,
my executors, administrators, and assigns, or such others as I, the said John
Bradley, my executors, administrators, and 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 OVENS,
APPLICABLE FOR BAKING BREAD AND PASTRY, ROASTING OR COOKING MEATS, AND
SIMILAR PURPOSES," upon the condition (amongst others) that I, the said John
Bradley, by an instrument in writing under my hand and seal, should par-
ticularly 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 John Bradley, 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
(that is to say)—
This Invention relates to domestic or kitchen ovens, which are usually set
or fixod adjoining the kitchen fire-grate, and when used for baking, &c., fire
from the grate is pushed underneath to heat the same.
My improvements consist in dispensing with fire underneath the oven by
the employment of a pipe or flue of metal or other suitable material applied to
the back or other convenient part of tho fire-grate, having an opening. thereto
and communicating with the flues of the oven, which are arranged so that tho
heated air or gases will be conducted from the fire to the top, sides, bottom,
and back of tho oven, and thenco to the chimney, wheroby 1 obtain a more
equal distribution of heat or temperature with less care or attention, and effect
a saving of fuel.

page_text: Having thus fully described the nature of my said Invention, and the
manner in which the same is to be performed, I desire it to be distinctly
understood that I do not confine myself to any particular shape or size of the
pipe or flue above mentioned, but I claim as my Invention, and which, to the
best of my knowledge and belief, has not been hitherto used within the realm,
the use of pipes or flues to convey and distribute heat from the fire in fire-
grates to the flues of ordinary ovens to heat them, instead of the usual method
of putting fire directly under the ovens.
In witness whereof, I, the said John Bradley, have hereunto set my
hand and seal, this Eleventh day of June, in the year of our Lord Ono
thousand eight hundred and fifty-eight.
Signed, sealed, and delivered by the within-
named John Bradley, in the presence of
W TASKER, Patent Agent,
Halifax.
JOHN BRADLEY. (L.S.)
