Year: 1879

page_text: LETTERS PATENT to Friedrich Hermann Felix Engel, Civil Engineer and Patent
Agent, in the City of Hamburg, Germany, for the Invention of "AN IMPROVED
COMPOSITION FOR PREVENTING THE OXIDIZING OF METALS." A communica-
tion from Adolph Bècker, trading under the Firm of Ad. Bècker, at Hamburg,
in the German Empire.
Sealed the 23rd March 1880, and dated the 27th September 1879.
PROVISIONAL SPECIFICATION left by the said Friedrich Hermann Felix
Engel at the Office of the Commissioners of Patents on the 27th September
1879.
FRIEDRICH HERMANN FELIX ENGEL, Civil Engineer and Patent Agent, in the
City of Hamburg, Germany. "AN IMPROVED COMPOSITION FOR PREVENTING THE
OXIDIZING OF METALS." A communication from Adolph Bècker, trading under the
Firm of Ad. Becker, at Hamburg, in the German Empire.
This improved composition for coating metals consists of the application of solid
hydrocarbons in combination with liquid hydrocarbons, aeteric, or fat-oils. Amongst
the solid hydrocarbons, preferably india rubber, paraffin, and ozokerit are used,
whilst amongst the liquid hydrocarbons and oils rectified petroleum, ligroine, and
turpentine-oil are preferably applied for the manufacture of the above composition.
A valuable composition, after this Invention, is produced by melting one part of
paraffin under moderate heat in a closed vessel, and by then adding and mixing
from two to four parts of rectified petroleum, ligroine, or turpentine-oil, with the
melted paraffin. According to the greater or smaller quantity of liquid which is
added, as above, the consistency of the composition varies. The latter is of pasty
consistency, and can be applied to the surface of the metals by means of a stiff
brush,

by the said Friedrich Hermann Felix Engel in the Great Seal Patent Office
on the 27th March 1880.
FRIEDRICH HERMANN FELIX ENGEL, Civil Engineer and Patent Agent, in the
City of Hamburg. "AN IMPROVED COMPOSITION FOR PREVENTING THE OXIDIZING
OF METALS." A communication from Adolph Becker, trading under the Firm of
Ad. Becker, at Hamburg, in the German Empire.
This improved composition for coating metals consists of the application of solid
hydrocarbons in combination with liquid hydrocarbons, aeteric, or fat oils. Amongst
the solid hydrocarbons, preferably india rubber, paraffin, and ozekerit are used,
whilst amongst the liquid hydrocarbons and oils, rectified petroleum, ligroine,
and turpentine-oil are preferably applied for the manufacture of the above
composition.
A valuable composition, after this Invention, is produced by melting one part of
paraffin under moderate heat, about 150° Fahrenheit, in a closed vessel, and by then
adding and mixing from two to four parts of rectified petroleum, ligroine, or
turpentine-oil, with the melted paraffin. According to the greater or lesser
quantity of liquid which is added, as above, the consistency of the composition
varies, the which latter is of pasty consistency, variable, as stated, and can be
applied to the surface of the metals by means of a stiff brush.
Having now described the nature and particulars of the said Invention, I
claim,―
The improved composition for coating metals to protect the same from oxidation,
consisting of a mixture of solid hydrocarbons and liquid hydrocarbons, aeteric, or
fat oils, substantially as herein described.
In witness whereof, I, the said Friedrich Hermann Felix Engel, have hereunto
set my hand and seal, this Fifteenth day of March, in the year of our Lord
One thousand eight hundred and eighty.
