66, Chancery Lane, in the County of Middlesex, Mechanical Draughts=
man, for the Invention of "AN IMPROVEMENT IN REFINING PETROLEUM
AND OTHER HYDROCARBON OILS."-A communication from abroad by
Robert Augustus Chesebrough, of New Rochelle, in the State of New
York, United States of Americà.
Sealed the 28th December 1865, and dated the 31st July 1865:
PROVISIONAL SPECIFICATION left by the said Alfred Vincent Newton
at the Office of the Commissioners of Patents, with his Petition; on
the 31st July 1865.
İ, ALFRED VINCENT NEWTON, of the Office for Patents, 66, Chancery Lane,
in the County of Middlesex, Mechanical Draughtsman, do hereby declare the
nature of the said Invention for "AN IMPROVEMENT IN REFINING PETROLEUM
AND OTHER HYDROCARBON OILS," to be as follows:-
This Invention relates to the refining of petroleum and other hydrocarbon
oils by filtration through animal charcoal, wood charcoal, or other filtering
medium.
The filter may consist of a vessel of wood or iron of cylindrical form,
having a diameter about one-fourth of its height open at the top; and per
forated at bottom with small holes: Over the perforäted bottom of this
vessel is placed a layer of cotton; cotton cloth; or other fibrous material to
prevent any particles of the filtering material from passing through the
perforations, and above this layer the vessel is about half filled with tlie
animal or wood charcoal or other filtering material:

page_text: The oil to be refined is, poured in at the top of the filter, which may be
kept filled up to the top, and after filtering through the charcoal or other
filtering material passes through the under layer of fibrous material and the
perforated bottom into a suitable receptacle. Petroleum or other hydro-
⚫ carbon oils filtered in this manner will be light in colour, have very little odour,
and be suitable according to its density for the purposes-either of lubrication
or illumination.
ISPECIFICATION in pursuance of the conditions of the Letters Patent, filed
by the said Alfred Vincent Newton in the Great Seal Patent Office
⚫ on the 31st January 1866.
TO ALL TO WHOM THESE PRESENTS SHALL COME, I, ALFRED
VINCENT NEWTON, of the Office of Patents, 66, Chancery Lane, in the County
of Middlesex, Mechanical Draughtsman, send greeting.
WHEREAS Her most Excellent Majesty Queen Victoria, by Her Letters
Patent, bearing date the Thirty-first day of July, in the year of our Lord One
thousand eight hundred and sixty-five, in the twenty-ninth year of Her reign,
did, for Herself, Her heirs and successors, give and grant unto me, the
-said Alfred Vincent Newton, Her special licence that I, the said Alfred
Vincent Newton, my-executors, administrators, and assigns, or such others as
·I, the 'said Alfred Vincent Newton, '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 "AN
IMPROVEMENT IN REFINING PETROLEUM AND OTHER HYDROCARBON OILS," being
a communication from abroad, upon the condition (amongst others) that I,
the said Alfred Vincent Newton, 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 Alfred Vincent Newton, do hereby
declare the nature of the 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) :-

page_text: This Invention relates to the refining of petroleum and other hydrocarbon
oils by filtration through animal charcoal (sometimes termed "bone black ")
wood charcoal, or other filtering medium.
In carrying out the Invention the filter may consist of a vessel of wood or
iron of any suitable form and size, but preferably of cylindrical form, aud
having a diameter about one-fourth of its height open at the top and per-
forated closely at bottom with small holes. Over the perforated bottom of
this vessel is placed and secured a layer of cotton, cotton cloth, or other
fibrous material to prevent any particles of the filtering material from passing
through the perforations, and above this layer the vessel is about half filled
with the animal or wood charcoal or other filtering material.
The oil to be refined or purified is poured in at the top of the filter, which
may be kept filled. After filtering through the charcoal or other filtering
material the oil passes through the under layer of fibrous material and the
perforated bottom into a suitable receptacle. Petroleum or other hydro-
carbon oils filtered in this manner will be light in color, have very little odor,
and be suitable according to its density for the purposes either of lubrication
or illumination.
Oils distilled from coal should preferably be re-distilled once in the ordinary
way before filtration as above described. Petroleum may be subjected to
such filtration either in its crude or natural state or after distillation.
Having now set forth the nature of the Invention of "An Improvement
in Purifying Petroleum and other Hydrocarbon Oils," and explained the
manner of carrying the same into effect, I wish it to be understood that under
the above in part recited Letters Patent I claim, the refining or purifying of
petroleum or other hydrocarbon oils by filtration through animal or wood
charcoal, or other filtering material or materials in the manner substantially
as herein described.
In witness whereof I, the said Alfred Vincent Newton, have hereunto
set my hand and seal, the Thirtieth day of January, in the year of
our Lord One thousand eight hundred and sixty-six.
Witness,
J. W. MOFFATT,
66, Chancery Lane.
