PROVISIONAL SPECIFICATION.
Improvements in the Thickening of Oil.
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 15, Earlsfield Road, Wandsworth Common, in the County of
Surrey, Manufacturing Chemist, do hereby declare the nature of this invention
to be as follows:-
This invention relates to an improved method of thickening linseed, cotton seed
and like oils for use in the manufacture of oil-skin, oil-silk, oil-cloth, floor-cloth,
linoleum and other similar materials, or as a lubricant.
In carrying out our invention we take a pure manganese soap (prepared from
linseed or other suitable oil, for instance in the manner described in the Specification
of former Letters Patent granted to us No. 11629 of 1890) conveniently in the
form of a solution in turpentine or in any other suitable solvent and we mix a
proportion of this solution with the oil to be treated. After impurities have
separated and been removed by subsidence or otherwise we pass a current of air
or oxygen into the clear mixture (which is advantageously maintained at a
temperature of 212 degrees Fahrenheit or thereabouts) and preferably by means
of the apparatus described in the Specification before referred to.
In practice we have found that a solution of one part by weight of manganese
soap in two parts of turpentine or other solvent, added to the oil to-be treated in
the proportion of two or three volumes of the solution to one hundred volumes of
the oil gives good results.

COMPLETE SPECIFICATION.
Improvements in the Thickening of Oil.
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 15, Earlsfield Road, Wandsworth Common, in the County of
Surrey, Manufacturing Chemist, do hereby declare the nature of this invention
and in what manner the same is to be performed to be particularly described
and ascertained in and by the following statement:-
This invention relates to an improved method of thickening linseed, and like
oils and converting them into a material to be used in the manufacture of oil-skin,
oil-silk, oil-cloth, floor-cloth, linoleum, lincrusta and other similar materials; also
thickening cotton-seed oil to be used as a lubricant or for other purposes in which
solidified or thickened oils may be employed.
In carrying out our invention we take about one part by weight of manganese soap
(by preference manganese linoleate prepared from linseed oil, for instance in the
manner described in the Specification of former Letters Patent granted to us No. 11629
of 1890) or a fatty acid manganese salt, and we dissolve it in about two parts by
weight of turpentine or other suitable solvent easily miscible with oil and we mix from
two to five measures of this solution with one bundred measures of the oil to be treated.
After separating insoluble matters or impurities by subsidence or otherwise we pass a
Price 8d.]

page_text: current of air or oxygen into the mixture (which is advantageously maintained at
a temperature of 212 degrees Fahrenheit or thereabouts). For this purpose
we make use of apparatus such as that described in the Specification before
referred to.
Linseed oil thus treated assumes an amber colour and acquires extraordinary
drying properties. We continue to pass air or oxygen through the oil until it has
acquired any desired degree of thickness short of that which would prevent the
passage of the air.
By our improved method we can, for example produce from linseed oil having a
density of 937, a clear transparent thickened oil of a pale amber colour with a
density of 997 at 70° Fahrenheit.
In practice we have found the above mentioned proportions of the materials
to give good results; the proportions may however be somewhat varied although
we do not advise any increase in the proportion of the manganese solution, as we
have, ascertained by numerous experiments that if too large a proportion of the
manganese linoleate be used the product is of inferior quality to that which we have
obtained by using the proportions mentioned.
For thickening cotton-seed oil we prefer to use about one measure of linoleate
solution to about four hundred measures of the oil.
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
1. The herein described method of thickening linseed and other oils by mixing
the oil to be treated with a manganese soap or a fatty acid salt of manganese easily
soluble in a liquid readily miscible with oil, such as turpentine, in abont the
proportions mentioned and exposing the mixture to the oxidising action of air or
oxygen, substantially as described.
2. The use for carrying out our process for thickening oil of the apparatus
described in the Specification of our Letters Patent No. 11629 of 1890.
