page_text: LETTERS PATENT to Edgar Townend Jarrold, of the City of Norwich,
in the County of Norfolk, and George John Yates, of Penketh, near
Warrington, in the County of Lancaster, for the Invention of "IMPROVE-
MENTS IN DEODORIZING PARAFFIN, PETROLEUM, ROCK-SHALE, AND OTHER
TT
PROVISIONAL SPECIFICATION left by the said Edgar Townend Jarrold
and George John Yates at the Office of the Commissioners of Patents,
with their Petition, on the 21st January 1864.
We, EDGAR TOWNEND JARROLD, of the City of Norwich, in the County of
Norfolk, and GEORGE JOHN YATES, of Penketh, near Warrington, in the
County of Lancaster, do hereby declare the nature of the said Invention for
"IMPROVEMENTS IN DEODORIZING PARAFFIN, PETROLEUM, ROCK-SHALE, AND OTHER
HYDROCARBON OILS," to be as follows:-
This Invention consists in acting upon paraffin, petroleum, rock shale, and
other hydrocarbon oils, when in the gaseous state, by any known metals or
the oxides of any known metals containing one or more equivalents of
oxygen, or by the hydrated oxides of any known metals containing one or
more equivalents of water.
We place the oil in a still heated in any suitable manner, and cause the
gases and vapours to pass through one or more heated vessels containing the
deodorizing agents, and from thence through a condenser into any receiving
vessel, or we pass the gases and vapours into one or more heated chambers
having shelves or boxes containing the deodorizing agents, from which
chamber the purified gases pass to the condenser.

page_text: SPECIFICATION in pursuance of the conditions of the Letters Patent, filed
by the said Edgar Townend Jarrold and George John Yates in the Great
Seal Patent Office on the 20th July 1864.
TO ALL TO WHOM THESE PRESENTS SHALL COME, we, EDGAR
TOWNEND JARROLD, of the City of Norwich, in the County of Norfolk, and
GEORGE JOHN YATES, of Penketh, near Warrington, in the County of
Lancaster, send greeting.
WHEREAS Her most Excellent Majesty Queen Victoria, by Her Letters
Patent, bearing date the Twenty-first day of January, in the year of our
Lord One thousand eight hundred and sixty-four, in the twenty-seventh
year of Her reign, did, for Herself, Her heirs and successors, give and grant
unto us, the said Edgar Townend Jarrold and George John Yates, Her
special license that we, the said Edgar Townend Jarrold and George John
Yates, our executors, administrators, and assigns, or such others as we,
the said Edgar Townend Jarrold and George John Yates, our 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 DEODORIZING PARAFFIN,
PETROLEUM, ROCK, SHALE, AND OTHER HYDROCARBON OILS," upon the condition
(amongst others) that we, the said Edgar Townend Jarrold and George John
Yates, our executors or administrators, by an instrument in writing under
our or their, or one of our or 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 we, the said Edgar Townend Jarrold and George
John Yates, do hereby declare the nature of our 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 acting upon paraffin, petroleum, rock shale, and
other hydro-carbon oils, when in the gaseous or vaporised state, with the
oxides of iron, using. either the dry oxides of iron or the bydrates of the oxides
of iron. We also use in conjunction with the oxides of iron, hydrate of lime
or slacked lime, using it either in the same vessel or pipe with the oxides of
iron, or in separate vessels or pipes.

page_text: In carrying out our said Invention into practical effect we cause the vapour
of the above named oils to pass from a still over the surface of hydrated
oxide of lime, and afterwards, but in the same operation, over the surface of
hydrated peroxide of iron contained in a suitable apparatus or purifying box,
which purifying box is heated to about 500 degrees Fah., or to a temperature
sufficiently high to prevent the condensation of the oil. After the vaporised
oil has passed over the deodorizing agents, it is then passed on through a
condenser into a receiving vessel.
We also effect the purification of hydrocarbon oils by the following sub-
stances:-The oxides or hydrated oxides of baryta, strontia, zinc, lead,
magnesia, tin, sesquioxide of alumina, peroxide of manganese, and common
alum, either alone or followed by the oxides of iron, as before mentioned in
the case of hydrated oxide of lime.
But for economy and efficiency we prefer the oxides of iron, and more par-
ticularly the peroxide of iron, either alone or with slacked lime, in the same
or in separate purifiers.
Having thus fully described the nature and particulars of our said Inven-
tion, and the manner in which the same is to be carried into practical
effect, we desire it to be understood that we claim the mode or method of
deodorizing paraffin, petroleum, rock-shale, and other bydrocarbon oils as
herein described.
In witness whereof, I, the said Edgar Townend Jarrold, for and on
behalf of myself and the said George John Yates, have hereunto set
my hand and seal, this Nineteenth day of July, in the year of our Lord
One thousand eight hundred and sixty-four.
Signed, sealed, and delivered by the
within-named Edgar Townend
Jarrold, in the presence of
E. J. HUGHES,
Patent Agent,
