Solicitors, of Frankfort-on-the-Main, in the Empire of Germany, for the
Invention of "A NEW COMPOUND FOR GREASING WOOL, AND A NEW METHOD
OF MANUFACTURING THE SAID COMPOUND." A communication from Julius
Jüngst and Christian Heinzerling, Doctor of Philosophy, of Biedenkopf, in the
Empire of Germany

PROVISIONAL SPECIFICATION left by the said Frank Wirth at the Office
of the Commissioners of Patents on the 20th August 1877.

FRANK WIRTH, of the Firm of Wirth and Company, Patent Solicitors, of
Frankfort-on-the-Main, in the Empire of Germany. "A NEW COMPOUND FOR
GREASING WOOL, AND A NEW METHOD OF MANUFACTURING THE SAID COMPOUND."
A communication from Julius Jüngst and Christian Heinzerling, Doctor of Philo-
sophy, of Biedenkopf, in the Empire of Germany.
The Invention relates to an improved compound named "olival" for greasing
wool, and to a method of manufacturing the said compound.
The method of manufacturing the said compound is as follows:-One part by
weight of resin (preferably colophony) is pulverized and mixed in the cold with one
part by weight of spirit of sal ammoniac, which must be free of lime, with 10 parts
by weight of water. These substances are agitated until a gelatinous mass is
obtained. In order to clean this mass from parts of non-dissolved resin and other
impurities the same is driven through a fine sieve. To this cleaned gelatinous mass
is then added an equal weight of rape oil, oleine, or any other fat oil suitable for
greasing wool, and mixed intimately in order to obtain a homogenous emulsion, to
which is added one-hundredth part by weight of glycerine.
For use this emulsion is mixed with half its weight of water, and employed directly
for greasing the wool.

The Invention relates to an improved compound to be named "olival," for greasing
wool, and to a method of manufacturing the said compound.
The method of manufacturing the said compound is as follows:-One part by
weight of resin (preferably colophony) is pulverized and mixed in the cold with one
part by weight of spirit of sal ammoniac, which must be free of lime, with 10 parts
by weight of water. These substances are, agitated until a gelatinous mass is
obtained. In order to clean this mass from parts of non-dissolved resin and other
impurities the same is driven through a fine sieve. To this clean gelatinous mass is
then added an equal weight of rape "oil, oleine, or any other fat oil suitable for
greasing wool, and mixed intimately in order to obtain a homogenous emulsion, to
which added one-hundredth part by weight of glycerine.
For use this emulsion is mixed with half its weight of water, and employed
directly for greasing the wool.
The advantages derived from the use of the composition are various; for instance,
30 to 40 per cent. of the greasing matter hitherto employed is saved, a finer spinning
is possible, also freedom from acids, and so the machinery is not injured.
The new composition can be removed from the wool by pure water simply, and
the yarn spun does not become rancid.
We claim,-
1st. As a new articleof manufacture a composition we name" olival," composed of
resin, spirit of sal ammoniac, water, glycerine, and a fat oil, in or about the proportions
set forth.
2nd. The method of manufacturing said compound by mixing resin, spirit of
sal ammoniac, water, glycerine, and a fat oil, in the manner and in or about the
proportions specified..
3rd. The use of the said compound for greasing wool.
"In witness whereof, I, the said Frank Wirth, have hereunto set my hand
and seal, this Seventh day of February, in the year of our Lord One
thousand eight hundred and seventy-eight.
