do hereby declare the nature of this invention to be as follows:-
To extract wool oil ("Lanolin") in a mechanical way the water in which the wool
has been scoured or the wool grease emulsions which have been collected in reservoirs,
must be freed from dirt before the wool oil can be separated. This is done in the
usual manner in a centrifugal machine.
The liquid when thus freed from dirt is exposed to continuous commotion in a
mechanical agitator. In consequence of this commotion the wool-oil ("Lanolin ")
will separate on the surface in the form of small particles which will agglomerate and
are easily removed with a scoop or ladle.
The remaining liquid is now placed in a separator in which a greasy emulsion will
be separated from the water, which will then be almost free from grease. This
emulsion is again placed in the agitator and the same operation is continued until all
the wool-oil ("Lanolin") is separated or extracted.
To simplify the operation the water in which the wool has been scoured can, after
it has been freed from dirt, be placed first in the separator to separate the water free.
from grease and then place the remaining greasy emulsion in the agitator.
The temperature has no material effect on the process, but it has been found that
the separation is a little quicker and more complete with a temperature of 20° to
40° C.

I, ALFRED JULIUS BOULT of 323 High Holborn in the County of Middlesex, M.I.M.E.,
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:
To extract wool oil ("Lanolin ") in a mechanical way the water in which the wool
has been scoured or the wool grease emulsions which have been collected in reservoirs,
must be freed from dirt before the wool oil can be separated. This is done in the
usual manner in a centrifugal machine.
The liquid when thus freed from dirt is exposed to continuous commotion in a
mechanical agitator. In consequence of this commotion the wool oil ("Lanolin")
will separate on the surface in the form of small particles which will agglomerate and
are easily removed with a scoop or ladle.
The remaining liquid is now placed in a separator in which a greasy emulsion will
be separated from the water which will then be almost free from grease. This
emulsion is again placed in the agitator and the same operation is continued until all
the wool oil ("Lanolin") is separated or extracted.
"
To simplify the operation the water in which the wool has been scoured can, after
it has been freed from dirt, be placed first in the separator to separate that water
which is free from grease and then place the remaining greasy emulsion in the
agitator.
The temperature has no material effect on the process but it has been found that
the separation is a little quicker and more complete with a temperature of 20° to
40° C.
Having now particularly described and ascertained the nature of the said inven-
tion, and in what manner the same is to be performed, as communicated to me
by my foreign correspondent, I declare that what I claim is ;-
The method of extracting or winning wool oil (Lanolin) mechanically from water
in which wool has been scoured or from other wool oil emulsions by subjecting the
fluid which has been previously freed from dirt to continuous commotion in a
mechanical agitator until the wool oil (Lanolin) separates and collects on the
surface.
