Sealed the 21st November 1854, and dated, the 30th September 1854.
PROVISIONAL SPECIFICATION left by the said George Fergusson Wilson
and George Payne at the Office of the Commissioners of Patents,
with their Petition, on the 30th September 1854.
We, GEORGE. FERGUSSON WILSON, of Belmont, Vauxhall, Managing
Director of Price's Patent Candle Company, and GEORGE PAYNE, of the
same Place, do hereby declare the nature of the Invention for "IMPROVEMENTS
IN THE MANUFACTURE AND APPLICATION OF ROSIN OIL" to be as follows:-
We have discovered that by distilling rosin oil, with the air excluded by
preference, by means of an atmosphere of steam, and then treating it with
sulphuric acid, and subjecting it to further distillation, with the air exluded by
preference, in an atmosphere of steam, and by treating rosin oil with sulphuric
acid, subjecting it to distillation, with the air excluded by preference, by
steam, products valuable for lighting, lubricating, or use in soap making, are
.

page_text: SPECIFICATION in pursuance of the conditions of the Letters Patent, filed
by the said George Fergusson Wilson and George Payne in the Great
Seal Patent Office on the 24th March 1855.
TO ALL TO WHOM THESE PRESENTS SHALL COME, we, GEORGE
FERGUSSON WILSON, of Belmont, Vauxhall, Managing Director of Price's
Patent Candle Company, and GEORGE PAYNE, of the same Place, send greeting.
WHEREAS Her most Excellent Majesty Queen Victoria, by Her Letters
Patent, bearing date the Thirtieth day of September, in the year of our Lord
One thousand eight hundred and fifty-four, in the eighteenth year of Her reign,
did, for Herself, Her heirs and successors, give and grant unto us, the said
George Fergusson Wilson and George Payne, Her special licence that we, the
said George Fergusson Wilson and George Payne, our executors, administra-
tors, and assigns, or such others as we, the said George Fergusson Wilson
and George Payne, 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
THE MANUFACTURE AND APPLICATION OF ROSIN OIL," upon the condition (amongst
others) that we, the said George Fergusson Wilson and George Payne, by an
instrument in writing under our hands and seals, or under the hand and seal
of one of us, 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 Scal Patent Office within six calendar months
next and immediately after the date of the said Letters Patent.
NOW KNOW YE, that we, the said George Fergusson Wilson and
George Payne, 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:-
We have discovered that by distilling rosin oil, with the air excluded by
preference, by means of an atmosphere of steam, and then treating it with
sulphuric acid, and subjecting it to further distillation, with the air excluded by
preference, in an atmosphere of steam, and by treating rosin oil with sulphuric
acid, subjecting it to distillation, with the air excluded by preference, by
steam, products valuable for lighting, lubricating, or use in soap making, are
obtained.
Having thus described the nature of our said Invention, we will proceed
to describe the manner of performing the same.

page_text: We first distil rosin oil in an atmosphere of steam, preferring to use super-
heated steam, introduced below the rosin oil, and so that it may rise up in
numerous streams through the rosin oil in a still, which process of distilling
rosin oil is, however, not in itself new. The distilled product of rosin oil is,
when cold, mixed with about ten per cent. in weight of sulphuric acid (of a
specific gravity about 1.8), the mixture being kept stirred for about two hours.
The rosin oil is then to be allowed to stand for about twenty-four hours,
and to be decanted from the sediment. The rosin oil is again distilled,
with the atmospheric air excluded, as before described, and the process will be
completed.
In place of first distilling the rosin oil, as above directed, it may be at once
treated with the sulphuric acid, and then distilled in a still, from which the
atmospheric air is excluded, but we prefer so to distil rosin oil before, as well
as after, acting on it by sulphuric acid. The purified products of rosin oil thus
obtained may be used in lamps suitable for burning heavy bydrocarbons.
Such purified products of rosin oil may also be mixed with ordinary
lubricating oils and greases for the purposes of lubricating machinery, and
such purified products of rosin oil may also be used in place of rosin in the
manufacture of soap.
In witness whereof, we, the said George Fergusson Wilson and George
Payne, have hereunto set our hands and seals, this Twenty-second
day of March, in the year of our Lord One thousand eight hundred
and fifty-five.
