PROVISIONAL SPECIFICATION left by the said Edward Primerose
Howard Vaughan at the Office of the Commissioners of Patents,
with his Petition, on the 18th December 1868.
I, EDWARD PRIMEROSE HOWARD VAUGHAN, of 54, Chancery Lane, in
the County of Middlesex, Patent Agent, do hereby declare the nature
of the said Invention for "IMPROVEMENTS IN THE MANUFACTURE OF ROSIN OLL,"
being a communication to me from abroad by Paul Curie, residing at
Bordeaux, in the Empire of France, to be as follows:-
This Invention consists in taking the rough or crude oils produced by
the distillation of rosin, and adding thereto lime or other oxide of the
alkaline or alkaline earthy metals, such as potash, soda, and magnesia in

page_text: the approximate proportion of ten per cent. thereof to the rough or
crude oil. The mixture so formed is then distilled, and a very pure oil,
which is applicable to a variety of useful purposes, is thus obtained in a
simple and economical manner.
*SPECIFICATION in pursuance of the conditions of the Letters Patent,
:
filed by the said Edward Primerose Howard Vaughan in the Great
Seal Patent Office on the 11th June 1869.
TO ALL TO WHOM THESE PRESENTS SHALL COME, I, EDWARD
PRIMEROSE HOWARD VAUGHAN, of 54, Chancery Lane, in the County of
Middlesex, Patent Agent, send greeting.
WHEREAS Her most Excellent Majesty Queen Victoria, by Her
Letters Patent, bearing date the Eighteenth day of December, in the year
of our Lord One thousand eight hundred and sixty-eight, in the thirty-
second year of Her reign, did, for Herself, Her heirs and successors, give
and grant unto me, the said Edward Primerose Howard Vaughan, Her
special licence that I, the said Edward Primerose Howard Vaughan, my
executors, administrators, and assigns, or such others as I, the said
Edward Primerose Howard Vaughan, 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 THE MANUFACTURE OF
ROSIN OIL," being a communication to me from abroad by Paul Curie,
residing at Bordeaux, in the Empire of France, upon the condition
(amongst others) that I, the said Edward Primerose Howard Vaughan,
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 im-
inediately after the date of the said Letters Patent.
NOW KNOW YE, that I, the said Edward Primerose Howard Vaughan,
LL

page_text: the same is to be performed, to be particularly described and ascertained
in and by the following statement, that is to say: -
The said Invention consists in incorporating with the rough or crude
oils produced by the distillation of pure rosin a quantity of lime or
other oxide of the alkaline or alkaline earthy metals, such as potash,
soda, and magnesia, and then submitting the mixture thus formed to
distillation. By this treatment the impurities contained in the rough
or crude oil remain in combination with the lime or other reagent
employed, whilst the oils distil over one after another, according to their
several densities, in a state of purity. The quantity of lime or other
reagent employed in this process depends on the degree of impurity of
the rough or crude oils under treatment, but as a general rule should be
about one-tenth part by weight of the latter. By means of this In-
vention a very pure oil, which is applicable as a lubricating agent and
to a variety of useful purposes, is thus obtained in a simple and
economical manner.
Having thus declared and ascertained the nature of the said In-
vention, and the manner in which it is to be performed, I would observe
in conclusion that what I consider novel and original, and therefore
claim as being the Invention secured to me by the said herein-before in
part recited Letters Patent is, the purification of rough or crude rosin
oils by their re-distillation in combination with lime or other oxide of
alkaline or earthy-alkaline metals, substantially as herein described.
In witness whereof, I, the said Edward Primerose Howard Vaughan,
have hereunto set my hand and seal, this Tenth day of June,
in the year of our Lord One thousand eight hundred and sixty-
nine.
E. P. H. VAUGHAN. (L.S.)
