A New or Improved Lanolin Compound and Process for Preparing
and Utilizing the same, specially applicable to the Preparation
of Lubricants.
A communication from abroad by ROBERT KRAUSE, of Wittenberge, in the
Kingdom of Prussia, Manufacturer.
I, WILLIAM PHILLIPS THOMPSON, F.C.S., M.I.M.E., of the Agency for
Foreign Patent Solicitors, 6, Lord Street, Liverpool, and 6, Bank Street, Man-
chester, both in the County of Lancaster, and 323, High Holborn in the County of
Middlesex, Civil Engineer, 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 :-
The new
This invention relates to a lanolin compound specially applicable for use in
preparing lubricating oils, and process of manufacturing the same.
product is also applicable for use in india-rubber manufacture and in scouring
fabrics.
Wool grease is treated with the requisite quantity of alkaline lye. The soap
formed thereby is then dissolved in water, and the solution obtained is filtered.
Another solution of alum or any other alumina salt in water is prepared and
then both solutions, namely, the alum solution and the soap solution, are poured
together.
A brown deposit is thereupon formed which may be called "aluminium-lanolate."
For the manufacture of lubricants, this deposit is dried and dissolved under the
action of heat in thin fluid mineral oils for producing a lubricating oil.
Any thin fluid mineral oils are suitable for the production of serviceable lubricants
and it is quite immaterial from what source they are obtained, and in the above
manner thick fluid cylinder oils can be produced with equal facility as can lubricating
oils of normal and small viscosity.
For use in india-rubber manufacture, the "aluminium-lanolate" is dissolved in a
small quantity (say 2 parts) of mineral oil, which solution presents the appearance
of a glossy, plastic, gelatinous substance, which may be mixed with raw india-rubber
or gutta percha, without interfering with the qualities of those bodies, but cheapens
them materially.
The operation of mixing lanolate with india-rubber may be executed in threo
different ways:-
1. Simply by melting the two substances together.
2. By pulverising the lanolate and mixing it with rubber.
3. By dissolving each of the substances and mixing them while in a plastic state.
After evaporation of the dissolving medium the result is a homogeneous substance
having all the qualities of india-rubber, or gutta percha but being a great deal
cheaper. It is to be observed that the same substances which dissolve india-rubber
or gutta percha will also dissolve lanolate.
The new product, the "aluminium-lanolate," besides being applicable for use in
india-rubber manufacture, may be used in scouring fabrics; and when used for such
latter purpose the aluminium-lanolate, (being simply a substitute for the usual
cleaning-agents used for scouring purposes), may be applied in the same manner as
such cleaning-agents, as will be found most suitable.
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 :-
1. The production and employment of "aluminium-lanolate" for the manufacture
of lubricating oils of any desired viscosity from thin fluid mineral oils.

bination with other substances as an india-rubber substitute.
3. The process of manufacture and employment of "aluminium-lanolate" in
combination with grease or mineral oils as a scouring agent in textile industries.
