WO, CHARLES RUMBLE and FREDERICK SEAR, both of Belmont Works Battersen
in the County of Surrey, Chemists do hereby declare the nature of our invention
for "IMPROVEMENTS IN THE PREPARATION OF OILS USED FOR LUBRICATING WOOLS
PREPARATORY TO SPINNING to be as follows:-
"
This invention has for its object improvements in the preparation of oils used for
lubricating wools preparatory to spinning.
It is well known that some oils used for this purposo are liable when on the
wool, to heat spontaneously to such a degree as to make them a source of danger
in the Mills. It has been proposed to obviate this difficulty by the addition of
mineral oil to the oil used for lubricating the wool. This, however, while reducing
the danger of spontaneous heating, is objectionable owing to the unsaponifiable
character of the mineral oil which renders. the oil used for lubricating the wool
difficult of removal in the scouring process.
Our invention enables us to prepare an oil which is not liable to dangerous
spontaneous heating, is a good lubricating agent and is readily removed in the
ordinary process of scouring.
We find that a metallic or ammonium salt or salts of a fatty acid or a metallic
or ammonium salt or salts of a resinous acid when dissolved in the oil used for
lubricating wools preparatory to spinning, (whether acid or neutral, or a mixture of
both) prevents spontaneous heating to a dangerous extent.
°
In carrying out our invention we take any convenient quantity of the oil to be
improved and add thereto from 1% to 10% of a salt or salts, as above named,
and heat, with constant stirring in an iron or other suitable vessel, at a
temperature not exceeding 260° Fahrenheit, until the salt or salts are completely
dissolved.
In carrying out our invention we prefer to use the potassium or sodium salt or
salts of tho fatty or resinous acids as they are the moro readily removed from the
wool in the process of scouring.

We CHARLES RUMBLE and FREDERICK SEAR both of Belmont Works Battersea
in the County of Surrey Chemists do hereby declare the nature of our invention
for "IMPROVEMENTS IN THE PREPARATION OF OILS USED FOR LUBRICATING WOOLS
PREPARATORY TO SPINNING" and in what manner the same is to be performed
to be particularly described and ascertained in and by the following statement :-
This invention has for its object improvements in the preparation of oils used for
lubricating wools preparatory to spinning.
It is well known that some oils used for this purpose are liable when on the
wool to heat spontaneously to such a degree as to make them a source of danger in
the mills. It has been proposed to obviate this difficulty by the addition of mineral
oil to the oil used for lubricating the wools. This however while reducing the
danger of spontaneous beating is objectionable owing to the unsaponifiable
character of the mineral oil which renders the oil used for lubricating the wool
difficult of removal in the scouring process.
Our invention enables us to prepare an oil which is not liable to dangerous
spontaneous heating is a good lubricating agent and is readily removed in the
ordinary process of scouring.
We find that a metallic or ammonium salt or salts of a fatty acid or a metallic
or ammonium salt or salts of a resinous acid when dissolved in the oil used for
lubricating wools preparatory to spinning (whether acid or neutral or a mixture
of both), prevents spontaneous heating to a dangerous extent.
In carrying out our invention we take any convenient quantity of the oil to
be improved and add thereto from 1% to 10% of a salt or salts as above named
and heat with constant' stirring in an iron or other suitable vessel at a
temperature not exceeding 260° Fahrenheit until the salt or salts are completely
dissolved:
In carrying out our invention we prefer to use the potassium or sodium salt' or
salts of the fatty or resinous acids as they are the more readily removed 'from the
wool in the process of scouring.
We can treat any of the oils commonly used for lubricating wools; as óleine,
olive oil, or other animal' or vegetable oils.
"
The oleine of commerce is an acid oil; the others are partly neutral and partly
acid!
A very convenient way to prepare them for 'use is by incorporating with them
the sodium salt of oleic acid in the manner and within the proportions stated. Less
conveniently caustic soda may be added and caused to combine with the acid
ingredient of the oil.
.:
。
In place of a sodium salt, salts of fatty acids.with other bases may be employed
as potassic or ammonium or metallic salts. So also in place of oleic acid the acid
component of the salt may be any fatty or resinous acid.

page_text: The proportion we generally adopt is 10% of the fatty or resinous salt but if a
smaller proportion be employed advantage is obtained but the protection from
spontaneous combustion is less complete.
We are able to employ oils from which more stearine than usual has been
extracted for our method of preparation increases the body of thin oils.
Having now particularly described and ascertained the nature of our said
invention and in what manner the same is to be performed we declare that what
we claim is
The preparation of oils used for lubricating wools preparatory to spinning by
combining the same with a metallic or ammonium salt or salts of a fatty or
resinous acid substantially as described.
