IMPROVE- MENTS IN MEANS OR APPARATUS FOR SUPPLYING FUEL OR HEAT TO STEAM BOILER OR OTHER FURNACES, APPLICABLE ALSO FOR VENTILATING MINES AND SIMILAR PURPOSES
Year: 1864

page_text: LETTERS PATENT to Abraham Rogers, of New Wortley, near Leeds, in
the County of York, Colliery Proprietor, for the Invention of "IMPROVE-
MENTS IN MEANS OR APPARATUS FOR SUPPLYING FUEL OR HEAT TO STEAM
BOILER OR OTHER FURNACES, APPLICABLE ALSO FOR VENTILATING MINES AND
SIMILAR PURPOSES."
Sealed the 3rd January 1865, and dated the 8th July 1864.
PROVISIONAL SPECIFICATION left by the said Abraham Rogers at
the Office of the Commissioners of Patents, with his Petition, on the
8th July 1864.
I, ABRAHAM ROGERS, of New Wortley, near Leeds, in the County of York,
Colliery Proprietor, do hereby declare the nature of the said Invention
for "IMPROVEMENTS IN MEANS OR APPARATUS FOR SUPPLYING FUEL OR HEAT TO
STEAM BOILER OR OTHER FURNACES, APPLICABLE ALSO FOR VENTILATING MINES AND
SIMILAR PURPOSES," to be as follows :-
This Invention consists, firstly, in applying to an ordinary furnace a coke
oven or apparatus which is now employed for burning and converting small
coal into coke. The oven is so placed and arranged that the products of
combustion therefrom will pass into the ordinary furnace, which is in con-
nection with and fed by coke from the oven. By this means the flames and
gases from the coke ovens which are now lost will be applied to the generation
of steam and other similar purposes, and the coal or fuel is only required to
be supplied once or twice a day.

page_text: Secondly, the Invention consists in applying a coke oven or ovens to the
top of the ventilating shaft or foul air shaft of a mine in such manner that the
oven or ovens will produce a draught or current to draw the foul air from the
mine. The oven is arched over and a flue formed above the arch and thence
to the top of the shaft, with openings to the burning fuel.
SPECIFICATION in pursuance of the conditions of the Letters Patent, filed
by the said Abraham Rogers in the Great Seal Patent Office on the
7th January 1865.

TO ALL TO WHOM THESE PRESENTS SHALL COME, I, ABRAHAM
ROGERS, of New Wortley, near Leeds, in the County of York, Colliery
Proprietor, send greeting.
WHEREAS Her most Excellent Majesty Queen Victoria, by Her Letters
Patent, bearing date the Eighth day of July, in the year of our Lord
One thousand eight hundred and sixty-four, in the twenty-eighth year
of Her reign, did, for Herself, Her heirs and successors, give and grant unto
me, the said Abraham Rogers, Her special licence that I, the said Abraham
Rogers, my executors, administrators, and assigns, or such others as I,
the said Abraham Rogers, 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 MEANS OR APPARATUS FOR SUPPLYING FUEL OR HEAT TO STEAM
BOILER OR OTHER FURNACES, APPLICABLE ALSO FOR VENTILATING MINES AND SIMILAR
PURPOSES," upon the condition (amongst others) that I, the said Abraham Rogers,
my executors or administrators, by an instrument in writing under my, or
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.
NOW KNOW YE, that I, the said Abraham Rogers, do hereby declare
the nature of my said Invention, and in what manner the same is to be per-
formed, to be particularly described and ascertained in and by the following
statement (that is to say): :-
This Invention consists, firstly, in applying to an ordinary furnace a coke

page_text: oven or apparatus which is now employed for burning and converting small
coal into coke. The oven is so placed and arranged that the products
of combustion therefrom will pass into the ordinary furnace which is in con-
nection with and fed by coke from the oven. By this means the flames and.
gases from coke ovens which are now lost will be applied to the generation of
steam and other similar purposes, and the coal or fuel only required to be
supplied once or twice a day.
Secondly, the Invention consists in applying a coke oven or ovens to the
top of the ventilating shaft or foul air shaft of a mine in such manner that
the oven or ovens will produce a draught or current to draw the foul air
from the mine. The oven is arched over and a flue formed above the arch
and thence to the top of the shaft, with openings to the burning fuel.
In carrying the first part of this Invention into practical operation it will be
readily seen that an ordinary coke oven or apparatus used for converting small
coal into coke may be placed in any convenient position near to an ordinary
furnace whether employed for the generation of steam or for other heating
purposes, with the flue from the oven opening into the furnace, so that the
flames and gases or products of combustion of the coal will be conducted into
the said furnace and thereby assist in the generation of steam or effect other
heating purposes to which the furnace may be applied. It will be evident
that a coke oven may be connected direct with a furnace and form part
of it, and ordinary furnaces of locomotive, stationary, or marine boilers, or
for other purposes, may be converted into coke ovens by charging them with
coal in a similar manner and igniting it at the front or feeding end. This
method of supplying the fuel to furnaces is particularly applicable to bakers'
ovens, stoves for warming churches, chapels, or other public or private
buildings, dyers' pans, and other similar purposes, where a constant supply of
heat is required. By this method of feeding furnaces a supply of fuel once
or twice per day is sufficient, and consequently a great saving of labour and
attention is secured by its adoption, and in practice it is found to prevent the
issue of opaque smoke from the chimney.
The manner of carrying into practice the second part of my Invention will
be understood by the following explanation:-I construct one or more coke
ovens near as convenient to the top of the foul air or ventilating shaft of a
mine, and connect each oven by a flue to the top of the said shaft which I
have covered up. The flue from the shaft passes over the coke oven (with
appertures opening to the burning fuel), thence passing along to the chimney,
the heat of the oven producing a current and consequently a draught on the
mine; or the flue from the ventilating shaft may enter the oven near the

page_text: feeding end thereof, when the ordinary flue from the oven to the chimney will
produce the draught required. It will also be evident that coke ovens may
be applied for ventilating mines by placing them at the bottom of the shafts
if desirable.
By the adoption of this Invention, the heat, which heretofore passed away
from coke ovens may be utilized in promoting the ventilation of mines, thus
saving the costs of fires in the shafts and the special attendance now required
for that purpose may be dispensed with.
In witness whereof, I, the said Abraham Rogers, have hereunto set my
hand and seal, this Fifth day of January, One thousand eight hundred
and sixty-five.
ABRAHAM ROGERS. (L.S.)
