IMPROVEMENTS IN EXTRACTING TURPENTINE AND TAR FROM RESINOUS WOOD
Year: 1865

page_text: LETTERS PATENT to Jean Antoine Pastorelly, of No. 74, Rue Curiol, in
the City of Marseilles, in the Empire of France, Merchant, for the
Invention of "IMPROVEMENTS IN EXTRACTING TURPENTINE AND TAR FROM
RESINOUS WOOD."
Sealed the 8th August 1865, and dated the 18th February 1865.
PROVISIONAL SPECIFICATION left by the said Jean Antoine Pastorelly
at the Office of the Commissioners of Patents, with his Petition, on the
18th February 1865.
I, JEAN ANTOINE PASTORELLY, of No. 74, Rue Curiol, in the City of Mar-
seilles, in the Empire of France, Merchant, do hereby declare the nature of
the said Invention for "IMPROVEMENTS IN EXTRACTING TURPENTINE AND TAR
FROM RESINOUS WOOD," to be as follows:-
This Invention consists in the direct extraction of spirit of turpentine and
tar from resinous woods by one or by two operations at pleasure by intro-
ducing steam into the cylinder to preserve the spirit of turpentine from
burning, or by putting a certain quantity of water into the said cylinder to
replace the steam.

page_text: An openwork cylinder is filled with resinous wood and then placed in a
somewhat larger cylinder which is placed on a stove or fire-place of any
description. Having closed this cylinder a fire is lit in the stove on which it
is placed, and another fire is at the same time lit in another stove or fire-place
on which rests a boiler containing water. The steam produced by this boiler
communicates by a pipe with the cylinder which contains the resinous wood,
and prevents the spirit of turpentine from burning. By putting water in the
first instance into the cylinder the steam boiler may be suppressed. A pipe
placed at the top of the cylinder gives passage to the spirit of turpentine
which condenses in passing through a refrigerator, and runs off into any sort
of vase or receptacle. The tap which gives passage to the steam is then shut
off, and the tar extracted by a pipe placed at the bottom of the cylinder,
which conducts it directly into a receptacle without passing by the refri-
gerator. The gas which escapes during the operation is conducted by a
special pipe into the fire-place to assist combustion, or is received into a gas-
holder and used for lighting.
SPECIFICATION in pursuance of the conditions of the Letters Patent, filed
by the said Jean Antoine Pastorelly in the Great Seal Patent Office on
the 12th August 1865.
TO ALL TO WHOM THESE PRESENTS SHALL COME, I, JEAN
ANTOINE PASTORELLY, of No. 74, Rue Curiol, in the City of Marseilles, in the
Empire of France, Merchant, send greeting.
WHEREAS Her most Excellent Majesty Queen Victoria, by Her Letters
Patent, bearing date the Thirteenth day of February, in the year of our Lord
One thousand eight hundred and sixty-five, in the twenty-eighth year of Her
reign, did, for Herself, Her heirs and successors, give and grant unto me, the
said Jean Antoine Pastorelly, Her special licence that I, the said Jean Antoine
Pastorelly, my executors, administrators, and assigns, or such others as I, the
said Jean Antoine Pastorelly, 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 "IMPROVE-
MENTS IN EXTRACTING TURPENTINE AND TAR FROM RESINOUS WOOD," upon the
condition (amongst others) that I, the said Jean Antoine Pastorelly, my
executors or administrators, by an instrument in writing under my, or their,

page_text: 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 Jean Antoine Pastorelly, 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, reference being had to the accompanying Sheet of
Drawing forming part of this my Specification, and to the figures and letters
of reference placed thereon, Figure 1 being an elevation of my apparatus,
Figure 2 shewing inner cylinder detached; Figure 3, section of same;
Figure 4, same seen from the back; Figure 5, section of refrigerator; and
Figure 6, one of the tubes of the refrigerator shortened.
My Invention consists in a new process for the direct extraction from
resinous woods of the essence or spirit of turpentine, the acetic acid, the gas,
and afterwards the tar in one or in two operations at will by introducing steam
into the cylinder in order to preserve the essence of turpentine from burning,
or by putting a certain quantity of water into the cylinder to replace the steam
and obtain charcoal for residuum.
The process is as follows:-The cylinder e is filled with resinous wood and
introduced into the cylinder a; this cylinder a is placed on a furnace in which
a fire is lit at the same time as in the furnace of the. boiler b, and the steam
is introduced into the cylinder a by means of a pipe, placing it in direct com-
munication with the boiler b. The essence of turpentine is firstly and
separately obtained by a pipe a' placed at the top of the cylinder a, it being
made to pass through the refrigerator c, and run off into a receiver through
the pipe c. The acetic acid is obtained with the essence of turpentine, and
afterwards extracted therefrom. The cock d, which gives passage to the
steam from the boiler 6 to the cylinder a is then closed and the tar extracted
by another pipe a fitted at the bottom of the cylinder a, which conducts it to
a receiver without passing through the refrigerator; is the feed pipe of the
steam boiler. During the operation the non-condensed gasses escape by the
pipe c, and are conducted by a special pipe into the furnace to serve for
fuel, or are received in a gasholder for lighting purposes. The steam may be
replaced by a proportionate quantity of water put into the cylinder a before
commencing the operation.
I would here observe that the steam may be introduced at all points of
the cylinder a, but principally in front, the better to envelope the resinous

page_text: substances with a jet of stream which will keep them from burning. To
sum up, I claim the exclusive application of the principles above set forth,
namely,―
Firstly, the means of directly extracting, firstly, the essence of turpentine
and the acetic acid from resinous woods passing them through a refrigerator
or condenser, and afterwards the tar by one or by two operations at will.
Secondly, the introduction of steam into the cylinder for preserving the
essence of turpentine from burning, as also the addition of a certain quantity
of water into the cylinder to replace the steam, the whole substantially as
herein-before described and illustrated on the annexed Sheet of Drawing.
In witness whereof, I, the said Jean Antoine Pastorelly, have hereunto
set my hand and seal, this Eighth day of August, in the year of
our Lord One thousand eight hundred and sixty-five.
J. A. PASTORELLY. (L.S.)
