IMPROVEMENTS IN APPARATUS FOR THE PRODUCTION, DISTILLATION, AND REFINING OF HYDROCARBON AND OTHER OILS FROM SHALE, CANNEL COAL, PEAT, LIGNITE, OR OTHER BITUMINOUS MINERALS
Year: 1866

page_text: LETTERS PATENT to Josiah Harris, of 41, Threadneedle Street, in the
City of London, for the Invention of "IMPROVEMENTS IN APPARATUS FOR
THE PRODUCTION, DISTILLATION, AND REFINING OF HYDROCARBON AND OTHER
OILS FROM SHALE, CANNEL COAL, PEAT, LIGNITE, OR OTHER BITUMINOUS
MINERALS."
Sealed the 30th April 1867, and dated the 3rd November 1866.
PROVISIONAL SPECIFICATION left by the said Josiah Harris at the
Office of the Commissioners of Patents, with his Petition, on the
3rd November 1866.
.I, JOSIAH HARRIS, of 41, Threadneedle Street, in the City of London, do.
5 hereby declare the nature of the said Invention for "IMPROVEMENTS IN
APPARATUS FOR THE PRODUCTION, DISTILLATION, AND REFINING OF HYDROCARBON
AND OTHER OILS FROM SHALE, CANNEL COAL, PEAT, LIGNITE, OR OTHER BITUMINOUS
MINERALS," to be as follows:-
The application of a fan or pump to the retorts or stills or pipes connected
therewith to be worked by hand, steam, or other suitable power to draw or
drive off the vapours, fumes, smoke, or gases as they are generated in the
retorts or stills. The action of the fan to be worked as above stated, and at
a high velocity imparts a centrifugal force to the air, therefore a pipe con-

page_text: nected with the fan, its other end being connected with the retort, causes &
partial vacuum in the pipes and draws its supply from the retorts, and
discharges it at the periphery of the fan.
SPECIFICATION in pursuance of the conditions of the Letters Patent, filed
by the said Josiah Harris in the Great Seal Patent Office on the 2nd
May 1867.
TO ALL TO WHOM THESE PRESENTS SHALL COME, I, JOSIAH
HARRIS, of 41, Threadneedle Street, in the City of London, send greeting.
WHEREAS Her most Excellent Majesty Queen Victoria, by Her Letters
Patent, bearing date the Third day of November, in the year of our Lord
One thousand eight hundred and sixty-six, in the twenty-ninth year of Her
reign, did, for Herself, Her heirs and successors, give and grant unto me,
the said Josiah Harris, Her special licence that I, the said Josiah Harris,
my executors, administrators, and assigns, or such others as I, the said
Josiah Harris, 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
APPARATUS FOR THE PRODUCTION, DISTILLATION, AND REFINING OF HYDROCARBON
AND OTHER OILS FROM SHALE, CANNEL COAL, PEAT, LIGNITE, OR OTHER BITU-
MINOUS MINERALS," upon the condition (amongst others) that I, the said
Josiah Harris, 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 Josiah Harris, do hereby declare
the nature of the 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 :-
This Invention has for its object the obtaining by a more ready and efficient
manner the seperation of hydrocarbon oils and their several products from
shale, cannel coal, peat, lignite, or other bituminous minerals. In effecting
this I place an ordinary exhausting fan or pump to be driven or worked by

page_text: steam or other motive power at the required volocity at the delivery pipe
leading from the retorts used in the manufacture of such hydrocarbon oils,
which fan or pump being set in motion creates a partial vacuum in the
retorts and pipes, and thus draws off the vapours, fumes, smoke, or gases
generated in the retorts during distillation, and I further employ this Invention
to draw off in a like manner such vapours, fumes, smoke, or gases as are
generated in the distillation of hydrocarbon oils, and I likewise in this part
of my Invention place the said exhausting fan or pump at the ordinary outlet
of the condensing worm leading from the still, and I furthermore employ
this Invention to draw off in a like manner from shale, cannel coal, peat,
lignite, or other bituminous minerals such vapours, fumes, smoke, or gases
as are generated in ovens or kilns for convertion into hydrocarbon oil.
Having thus set forth the nature of my said Invention, and in what
manner the same is to be performed, I claim in the above recital, Letters
Patent, the application of an exhausting fan or pump to the purposes above
set forth.
In witness whereof, I, the said Josiah Harris, have hereunto set my hand
and seal, this First day of May, in the year of our Lord One thousand
eight hundred and sixty-seven.
JOSIAH HARRIS. (L.S.)
