Year: 1862

page_text: LETTERS PATENT to John Thomas Oakley, of Grange Road, Bermondsey,
in the County of Surrey, for the Invention of "IMPROVEMENTS IN HEATING
STOVES EMPLOYED FOR DRYING AND OTHER PURPOSES."
Sealed the 13th February 1868, and dated the 18th August 1862.
PROVISIONAL SPECIFICATION left by the said John Thomas Oakley at the
Office of the Commissioners of Patents, with his Petition, on the 18th
August 1862.
I, JOHN THOMAS OAKLEY, of Grange Road, Bermondsey, in the County of
Surrey, do hereby declare the nature of the said Invention for "IMPROVEMENTS
IN HEATING STOVES EMPLOYED FOR DRYING AND OTHER PURPOSES," to be as
follows:-
This Invention consists in improvements in heating stoves employed for
drying and other purposes, which I propose to effect by the supply of heated
vapour produced from steam in the following manner:-It is proposed to
employ the steam from any common steam boiler or steam generator, or to use
the steam from the exhaust pipe of a steam engine, and by a suitable pipe or
pipes to conduct it to a superheater, which it is proposed to build either within
the boiler furnace, or within some portion of the boiler brickwork with a
separate furnace, or to erect the superheater and furnace separately, and by
the application of fire in the furnace, or of gas suitably applied, to produce
heated vapour of the temperature required, and to convey such heated vapour
through suitable pipes or flues of iron, fire-brick, or earthenware, to the stove
or stoves to be heated.

by the said John Thomas Oakley in the Great Seal Patent Office on the
18th February 1863.
TO ALL TO WHOM THESE PRESENTS SHALL COME, I, JOHN
THOMAS OAKLEY, of Grange Road, Bermondsey, in the County of Surrey,
send greeting.
WHEREAS Her most Excellent Majesty Queen Victoria, by Her Letters
Patent, bearing date the Eighteenth day of August, in the year of our Lord One
thousand eight hundred and sixty-two, in the twenty-sixth year of Her reign
did, for Herself, Her heirs and successors, give and grant unto me, the said
John Thomas Oakley, Her special licence that I, the said John Thomas Oakley,
my executors, administrators, and assigns, or such others as I, the said John
Thomas Oakley,
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
HEATING STOVES EMPLOYED FOR DRYING AND OTHER PURPOSES," upon the condition
(amongst others) that I, the said John Thomas Oakley, my executors or
administrators, by an instrument in writing under my, or their, or, one of
their hands and seals, 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 John Thomas Oakley, 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 consists in improvements in heating stoves employed for
drying and other purposes, which I propose to effect by the supply of heated
vapour produced from steam in the following manner:-It is proposed to
employ the steam from any common steam boiler or steam generator or to use
the steam from the exhaust pipe of a steam engine, and by a suitable pipe or
pipes to conduct it to a superheater, which it is proposed to build either within
the boiler furnace, or within some portion of the boiler brickwork, with a
separate furnace, or to erect the superheater and furnace separately, and by
the application of fire in the furnace or of gas suitably applied to produce

page_text: heated vapour of the temperature required, and to convey such heated vapour
through suitable pipes or flues of iron, fire-brick, or earthenware, to the stove
or stoves to be heated.
And in order to explain my said Invention more completely I now proceed
to describe the means by which these improvements may be carried into
practical effect, as follows:-
I propose to employ steam superheated to any degree of temperature, and
to apply same to apparatus used for drying or dessicating purposes; also to
ovens used by bakers, and apparatuses used for cooking, and for warming
buildings. I take, for example, neat steam of any degree of pressure, obtained
either from a steam boiler or other steam generator, or the exhaust steam
from a steam engine, and I raise the temperature of such steam by passing
same through a superheater composed of an indefinite number of divisions, and
made either of iron, earthenware, or brick, said superheater being built either
within the boiler, furnace, or the brickwork setting of the boiler; or said
superheater may be separate therefrom, and complete within itself, and be
fixed in any position most suitable, either near to, or away from, or within the
stove or other heating, drying, or warming apparatus. I propose to conduct
the superheated steam or vapour through pipes, channels, or chambers formed
either of iron, earthenware, or brick, as may be found most desirable.
Having now fully described the nature and object of my said Invention of
"Improvements in Heating Stoves employed for Drying and other Purposes,"
and the means by which the same may be effected, I hereby declare my
Invention to consist in, and I claim the use of steam superheated as above
described, and the application thereof to stoves, baking ovens, apparatus for
cooking, and warming buildings, for the purpose of heating same, as above
stated, as constituting improvements in apparatus employed for the above
purposes.
In witness whereof, I, the said John Thomas Oakley, have hereunto set
my hand and seal, this Eighteenth day of February, in the year of
our Lord One thousand eight hundred and sixty-three.
JOHN THOMAS OAKLEY. (L.B.)
