Rue Fontaine St. George, Paris, for the Invention of "IMPROVEMENTS IN
THE MANUFACTURE OF OIL FROM Rosix"
THE MANUFACTURE O
OF OIL PROM ROSIN"
Sealed the 29th March 1854, and dated the 21st January 1854.
PROVISIONAL SPECIFICATION left by the said Cyprien Marie Tessié
du Motay at the Office of the Commissioners of Patents, with his
Petition, on the 21st January 1854.
I, CYPRIEN MARIE TESSIE DU MOTAY, Chemist, of 24, Rue Fontaine
St. George, Paris, do hereby declare the nature of my said Invention for
"IMPROVEMENTS IN THE MANUFACTURE OF OIL FROM ROSIN" to be as follows:-
This Invention consists of improvements in obtaining oil from rosin and in
treating such oil. For this purpose rosin is placed in a still with hydrate
of lime or, alkali, and distilled over. The oil obtained is mixed with hydrate
of lime or alkali, and again distilled. The oil is then subjected to the
action of sulphuric acid, and allowed to settle; the oil is run off or separated,
and again treated with sulphuric acid; it is allowed to settle, and the oil run
off or separated.
The oil is next distilled, mixed with charcoal (animal or vegetable) or with
charcoal and carbonated alkali. The oil is filtered through animal charcoal
or other suitable matter. The residual matters are made into lubricating
materials.

TO ALL TO WHOM THESE PRESENTS SHALL COME, I, CYPRIEN
MARIE TESSIE DU MOTAY, Chemist, of 24, Rue Fontaine St. George, Paris,
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 fifty-four, in the seventeenth year of Her
reign, did, for Herself, Her heirs and successors, give and grant unto me, the
said Cyprien Marie Tessié du Motay, Her special licence that I, the said
Cyprien Marie Tessié du Motay, my executors, administrators, and assigns,
or such others as I, the said Cyprien Marie Tessié du Motay, my execu-
tors, 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 THE MANUFACTURE OF OIL FROM ROSIN,"
upon the condition (amongst others) that I, the said Cyprien Marie Tessié
du Motay, by an instrument in writing under my hand and seal should par-
ticularly 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 Cyprien Marie Tessié du Motay,
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 thereof (that is to say) :-
This Invention consist of improvements in obtaining oil from rosin, and in
treating such oil. For this purpose rosin is placed in a still with hydrate of
lime or alkali, and distilled over. The oil obtained is mixed with hydrate of
lime or alkali and again distilled. The oil is then subjected to the action
of sulphuric acid, and allowed to settle. The oil is run off or separated and
again treated with sulphuric acid, and it is allowed to settle, and the oil run off'
or separated. The oil is next distilled, mixed with charcoal (animal or vege-
table) or with charcoal and carbonated alkali. The oil is filtered through
animal charcoal or other suitable matter. The residual matters are made into
lubricating materials.

page_text: And in order that my said Invention may be most fully understood and
readily carried into effect, I will proceed to describe more in detail the process
which I employ.
First, I distil the rosin, either alone or, by preference, mixed with about ten
per cent. of hydrated lime or alkali, and in this manner I obtain an oil.
Second, I mix the oil thus obtained with from 10 to 20 per cent. of hydrated
lime and again distil.
Third,, the oil obtained by this second operation is agitated in a suitable
apparatus with from six to ten, per cent. by weight of sulphuric acid of com-
merce,, after which the liquids are allowed to separate, and a substance like tar
sinks to the bottom of the vessel.
The oil which floats on the surface is drawn off and again treated in the
same manner with sulphuric acid, in the proportion of about four or five
per cent. When the liquid has again separated (generally at the end of
twelve or eighteen hours) the oil is again drawn off from the precipitated
tar..
Fourth, the oil is mixed with from five to ten per cent. of animal charcoal,
or a mixture of charcoal and the carbonate of either of the alkalies or vegetable
charcoal may be used in place. of animal charcoal, but I consider animal
charcoal to be preferable. The oil thus mixed is again distilled.
Fifth, the oil obtained is filtered, by preference, through a bed of animal
charcoal, but other filtering material may be employed. In place of treating
the oil with sulphuric acid as above described, the oil may be purified by again
distilling with from ten to fifteen-per cent. of chloride of zinc.
After the distillation with lime there remains in the vessel a mixture of lime
and oil. This substance I mix with the tar resulting from the action of
sulphuric acid, and with a small quantity, say from ten to fifteen per cent. of
rosin oil, so as to obtain a substance of a suitable consistency, and which I use
for lubricating machinery. Or a grease may be formed by dissolving the lime
residue in rosin oil, and quick lime may be added in quantities sufficient to
obtain the desired consistency.
I will now describe a form of lamp which I have found to be well suited for
burning the oil obtained by my process.
The cylindrical wick carrier a, b, c, d, a, b, c, d, Figure 1, is bevilled off'
interiorly, as shewn at a, a'. The glass carrier is composed of two concentric
cylinders united together at intervals. The first cylinder e, f, e, f, slides on
the wick carrier; the second cylinder g, h, i, g, h, i', is turned up at k, k', to
hold the glass, and is contracted at h, i, h', ', so as to direct the current of air
on to the wick; over the flame is placed a metallic disc p, q, p', q', which is

page_text: mounted on the wire m, n. The distance of the disc from the burner can
be adjusted at will by turning the key. At the bottom of the wick carrier at
ff, there is a piece of metallic cloth..
Figure 2 shews another form of lamp, which is also well adapted for con-
suming this description of oil. A is a wick carrier of the ordinary description;
B is a tube which slides thereon and carries the platform which supports the
chimney and also an inverted glass cone c, at the upper end of which is a hole
through which the flame passes. This glass C directs the current of air and
causes it to impinge on the flame, so as to produce perfect combustion. It will
be seen that by sliding the tube B on the wick carrier A, the distance between
the glass C and the burner can be varied. There is a piece of wire cloth at D
to prevent the flame from being influenced by currents of air..
Having thus described the nature of my Invention, and the manner of per-
forming the same, I would have it understood that I do not confine myself to
the exact details described. But what I claim is, the method herein described
of obtaining and treating oil from rosin.
In witness whereof, I, the said Cyprien Marie Tessie du Motay, have
hereunto set my hand and seal, this Eighteenth day of July, in the
year of our Lord One thousand eight hundred and fifty-four.
Witness.
