Year: 1855

page_text: LETTERS PATENT to James Greenshields, of Glasgow, in the County of
Lanark, North Britain, Manufacturer, for the Invention of "IMPROVE.
MENTS IN THE MANUFACTURE OR PRODUCTION OF DRYING OLEAGINOUS COM-
POUNDS."
Sealed the 15th January 1856, and dated the 3rd November 1855.
PROVISIONAL SPECIFICATION left by the said James Greenshields at
the Office of the Commissioners of Patents, with his Petition, on the
3rd November 1855.
I, JAMES GREENSHIELDS, of Glasgow, in the County of Lanark, North
Britain, Manufacturer, do hereby declare the nature of the said Invention
for "IMPROVEMENTS IN THE MANUFACTURE OR PRODUCTION OF DRYING OLEAGINOUS.
COMPOUNDS" to be as follows, that is to say:-
This Invention relates to the use of resin or rosin oil, that is to say, the oil.
which is produced by the distillation of rosin or resinous matter, in combination.
or after treatment with manganese, oleaginous matter, or other drying sub-
stances, for the production of a drying substance suitable for waterproofing
purposes, as well as for general protective coatings and pigments. . The oil
preferred for mixing with the rosin oil is the ordinary linseed oil of commerce."
The two oily ingredients in proportions to suit especial requirements are mixed
or commingled in their raw unboiled state, and the mixture is then boiled, when
it is fit for use; or the mixture of the two oils is distilled. Or, instead of mixing
the two oils in the manner herein-before described, the oily substance.or com-
pound may be produced by distilling rosin or resin with common manganese,
or with litharge, or with other drying substances. The process of manufacture

page_text: or production may be varied in many ways; the essence of the Invention being
the adaptation or use of resinous matter for producing a drying oleaginous
mixture or mass. This resinous mixture answers excellently for waterproofing
woven fabrics and other goods or surfaces, as it forms a coating quite impervious
to moisture, whilst it is much cheaper than the ordinary waterproofing materials.
It is also cheap and effective in its use for producing paints or pigments.
SPECIFICATION in pursuance of the conditions of the Letters Patent, filed
by the said James Greenshields in the Great Seal Patent Office on the
2nd May 1856.
TO ALL TO WHOM THESE. PRESENTS SHALL COME, .I, JAMES
GREENSHIELDS, of Glasgow, in the County of Lanark, North Britain, Manu-
facturer, send greeting.
WHEREAS Her most Excellent Majesty Queen Victoria, by. Her Letters
Patent, bearing date the Third day of November, in the year of our Lord One
thousand eight hundred and fifty-five, in the nineteenth year of Her reign,
did, for Herself, Her heirs and successors, give and grant unto me, the said
James Greenshields, Her special license that I, the said James Greenshields,
my executors, administrators,, and assigns, or such others as I, the said James
Greenshields, my executors, administrators, or 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 OR PRODUCTION OF DRYING OLEAGINOUS COMPOUNDS," upon the
condition (amongst others) that I, the said James Greenshields, by an
instrument in writing under my hand and seal, 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 James Greenshields, do hereby declare
the nature of my said Invention, and in what manner the same is to be per-
formed, to be particularly described and ascertained in and by the following
statement in writing, that is to say:-
My said Invention relates to the use of resin or rosin oil, that is to say, the
oil which is produced by the distillation of rosin or resinous matter in com-

page_text: bination or after treatment with manganese, oleaginous matter, or other drying
substances, for the production of a drying substance suitable for waterproofing
purposes, as well as for general protective coatings and pigments. The oil
preferred for mixing with the rosin oil is the ordinary linseed oil of commerce.
The two oily ingredients in proportions to suit especial requirements are mixed
or commingled in their raw unboiled state, and the mixture is then boiled,
when it is fit for use; or the mixture of the two oils is distilled. Or, instead
of mixing the two oils in the manner herein-before described, the oily substance
or compound may be produced by distilling rosin or resin with common man-
ganese, or with litharge, or with other drying substances. The process of
manufacture or production may be varied in many ways; the essence of the
Invention being the adaptation or use of resinous matter for producing a
drying oleaginous mixture or mass. This resinous mixture answers excellently
for waterproofing woven fabrics and other goods or surfaces, as it forms a
coating quite impervious to moisture, whilst it is much cheaper than the
ordinary waterproofing materials. It is also cheap and effective in its use for
producing paints or pigments.
Having now described and particularly ascertained the nature of my said
Invention, and the manner in which the same is or may be used or carried
into effect, I may observe, in conclusion, that I do not confine or restrict
myself to the precise details or arrangements which I have had occasion
to describe or refer to, as many variations may be made therefrom without
deviating from the principles or main features of my Invention; but what
I consider to be novel and original, and therefore claim as the Invention
secured to me by the herein-before in part recited Letters Patent, is,-
First, the herein-before described systems or modes of manufacturing or
producing drying oleaginous compounds, by combining or treating resin or rosin
oil with suitable ingredients or materials having drying properties.
Second, the application and use of resin or rosin oil in producing a drying
oleaginous compound, by combining or treating it with suitable ingredients or
materials having drying properties, as herein-before described.
In witness whereof, I, the said James Greenshields, have hereunto set
my hand and seal, this Thirtieth day of April, One thousand eight
hundred and fifty-six.
JAMES GREENSHIELDS. (L.S.)
