PROVISIONAL SPECIFICATION.
Improved Process of Producing Consistent and Semi-consistent Fats
and Oils without Applying Heat.
I, GUSTAV POMMERHANZ, of 37, Mariahilfer Strasse, in the City of Vienna,
in the Empire of Austria, Gentleman, do hereby declare the nature of this inven-
tion to be as follows:-
This invention relates to an improved process of producing consistent and
semi-consistent fats, greases and oils without applying heat, steam etc. and is carried
out in the following manner.
65
About 20 parts of the grease known in commerce as yolk" in a liquid state,
and about 80 parts of mineral, rape or olive oil, or the residues of petroleum, are
thoroughly mixed in a vessel, cistern or the like by means of a suitable stirring
device.
Tallow, cocoa-butter, stearine, paraffin, ceresine, wax or similar fats, resins or
resinous oil, as well as every other vegetable or mineral oil or fat may be added to
the above constituents in suitable proportions.
About 40 parts of this compound is again thoroughly stirred or agitated with
3 parts lye or a solution of soda in an appropriate vessel or receptacle whereupon
the congelation of the mass immediately commences.
In order to color the mass produced as above described, palm oil or more or less
of a earth or other colour suitable for preparing oil colours may be added as
desired during the mixing.

COMPLETE SPECIFICATION.
Improved Process of Producing Consistent and Semi-consistent Fats
and Oils without Applying Heat.
I, GUSTAV РоMMERHANZ of 37, Mariahilfer Strasse, Vienna, in the Empire of
Austria, Gentleman, 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 a process of solidifying mineral oils or rendering them so
far semi-solid or viscous that they will not flow at ordinary temperatures and will
be suitable for lubricating and greasing purposes.
This result has heretofore been accomplished by saponifying vegetable or animal
fats or oils, evaporating the water as far as possible, aud then slowly dissolving the
soaps thus formed in the heated mineral oil by stirring.
I have discovered a simple process whereby the previous making of the soap,
heating, stirring, etc., may be dispensed with and the oil may be brought to any
required degree of consistency and rendered suitable for use as a lubricant or for
greasing yarn and leather, for example, in a rapid and inexpensive manner.
This process is based on the property possessed by wool fat or grease ("yolk "
or "suint") of dissolving or incorporating with most salts and of being soluble in
mineral oils. I have discovered that such wool fat and salts when combined with
[Price 8d.]

page_text: mineral oils have the effect of solidifying them, the degree of solidification
depending on the quantity of wool fat employed.
In addition to the wool fat and salts it is often advantageous to add some caustic
alkali whereby the acids contained in the oil are neutralized and the degree of
solidification is increased.
In carrying my process into effect I proceed as follows:-With seventy pounds
of mineral oil I thoroughly mix twenty pounds of melted wool fat. I then add
three pounds of caustic soda lye at 39° B. and six pounds of common salt (chloride
of sodium) dissolved in as little water as possible. The whole immediately
combines in the form of a stiff yellow mass, particularly adapted for lubricating
machinery and for greasing yarn and leather.
Having now particularly described and ascertained the nature of the said inven-
tion, and in what manner the same is to be performed, I declare that what I
claim is :-
1. The herein described process of solidifying mineral oil by incorporating there-
with wool fat and a salt, as specified.
2. The herein described process of solidifying mineral oil by incorporating there-
with wool fat, a salt, and caustic alkali, as specified.
3. As a
new article of manufacture, solidified mineral oil in which the
solidification has been produced by the incorporation therewith of wool fat and a
salt, as specified.
