The Manufacture of an Improved Preparation of Dryers or Siccative

We, WALTER NOEL HARTLEY, of 36, Waterloo Road, Dublin, in the County
of Dublin, Ireland, Fellow of the Royal Society, Professor of Chemistry, in the
Royal College of Science, Dublin, and WILLIAM EDMUND BRANDFORD
BLENKINSOP, of 16, Earlsfield Road, Wandsworth Common, in the County of
Surrey, Manufacturing Chemist, do hereby declare the nature of this invention to
be as follows:-
Our invention relates to the manufacture of an improved preparation to be mixed
with oil paints in order to increase their drying properties.
It is known that manganese linoleate or the manganese soap of the fatty acids
from linseed oil is a most powerful drying agent.
In order to make it useful for the purpose of painters we have prepared a
mixture containing manganese linoleate in a convenient form by which a sufficiency
may be thoroughly incorporated with oil paints when the same are being mixed
for use.
In making our preparation we take a metallic oxide or metallic salt which can
have no injurious action on the paints such as oxide of zinc, the carbonate or the
sulphate of lead, an inactive substance such as china, clay, silica, or kiselguhr. We
reduce it to a fine powder and intimately mix and incorporate therewith the
manganese linoleate:
The mixing may be carried out by heating the materials to a steam heat and
triturating in a mortar; or by dissolving manganese linoleate in turpentine or other
suitable solvent and thoroughly mixing the solution with the powder by trituration
or otherwise.
We obtain good results by taking the materials in about the following proportions,
that is to say for the solution forty parts by weight of manganese linoleate and one
hundred and twenty parts by weight of turpentine or thereabouts. The solution
afterwards mixed with about one thousand parts by weight of zinc oxide but we do
not limit ourselves to these proportions. So prepared this powder may be used for
mixing with paints.
To prepare a liquid dryer we treat an oil containing about one per cent. of
manganese linoleate according to the process. described in our Specification
No. 11629 of 1890 the treatment being prolonged until the oil becomes thickened.
The thickened oil is then diluted with a suitable solution of manganese, linoleate
until the mixture has a density of about that of linseed oil and contains 10% more
or less of the linoleate as may be desirable. The dryer will then completely mix
with oil paints or oil without difficulty.

and in what manner the same is to be performed, to be particularly described and
ascertained in and by the following statement
:-
Our invention relates to the manufacture of an improved preparation to be mixed
with oil paints in order to increase their drying properties.
It is known that manganese linoleate or the manganese soap of the fatty acids
from linseed oil is a most powerful drying agent.
In order to make it useful for the purpose of painters we have prepared a

sufficiency may be thoroughly incorporated with oil paints when the same are being
mixed for use.
In making our preparation we take a metallic oxide or metallic salt which can
have no injurious action on the paints such as oxide of zinc, the carbonate or the
sulphate of lead, an inactive substance such as china-clay, silica, or kieselguhr.
We reduce it to a fine powder and intimately mix and incorporate therewith the
manganese linoleate.
The mixing may be carried out by heating the materials to a steam heat and
triturating in a mortar; or by dissolving manganese linoleate in turpentine or other
suitable solvent and thoroughly mixing the solution with the powder by trituration
or otherwise.
We obtain good results by taking the materials in about the following proportions,
that is to say, for the solution forty parts by weight of manganese linoleate and one
hundred and twenty parts by weight of turpentine or thereabouts. The solution is
afterwards mixed with about one thousand parts by weight of zinc oxide but we do
not limit ourselves to these proportions. So prepared this powder may be used for
mixing with paints.
To prepare a liquid dryer we treat an oil containing about one per cent. of

until the mixture has a density of about that of linseed oil and contains 10% more
or less of the linoleate as may be desirable. The dryer will then completely mix
with oil paints or oil without difficulty.
Having now particularly described and ascertained the nature of our said inven-
tion and in what manner the same is to be performed, we declare that what we
claim is :
The manufacture and use of the improved preparations of dryers or siccative
materials for mixing with paints, formed by mixing and combining the ingredients
herein mentioned substantially as described.
