An Improved Polishing Medium.
We, PAUL THEIL, Joiner, of 1 Friedrichshagenerstrasse Köpenick, and KARL
SCHIMITZEK, Brush Manufacturer, of 1* Müggelsheimerstrasse, Köpenick, in the
Empire of Germany, do hereby declare the nature of this invention to be as
follows:-
In polishing articles of wood it has hitherto been usual first to rub them with
oil and smooth them with pumice-stone, and then to coat or rub them with &
comparative weak alcoholic solution of shellac, thus imparting brilliancy to the
surface to be polished. This first or initial polish was generally followed by a
second one, which was performed with a stronger solution of shellac; and finally a
coating of spirits of wine and one of an alcoholic solution of benzoiu or-
benzoin was applied, if necessary.
guin-
Polish of this kind has been found, however, to possess the serious disadvantage
that it was liable to become dull in a very short time through rapid exudation.
Again it has been observed that surfaces painted some time back, especially.if
painted with oil-paint, are apt very soon to show cracks, a fact most probably
ascribable to the circumstance that the polishes above referred to are readily
permeated by the oil contained in the paint; the consequence being that the paint
underlying the polish, having given off its oil, dries up, and, by contracting, causes
the external polish to break. It has therefore been deemed necessary, before
proceeding to polish wooden articles painted with oil-paint to remove therefrom
as completely as possible the old coating of paint.
The object of this invention is to avoid these inconveniences, and such object is
accomplished by employing a polishing medium impermeable to oil or fatty bodies
and consequently allowing of no exudation.
The trials to which various descriptions of resin have been subjected for this
purpose, have shown that the resin of the guaiacum tree, or lignum vitæ is best
calculated to impart the desired properties to the polish. Polish prepared with
this resin, being impermeable to oil, is not liable to exudation, and probably for
this reason, the polishing process itself is greatly facilitated one coat of polish
being generally sufficient to produce a satisfactory result.
24;
Guaiacum polish prepared by mixing the following substances in or about in the
proportions named has been found to answer the purpose very well;
Polish prepared in this manner enables any article, previously rubbed off or
0 smoothed (with or without oil), to be finally polished in one operation, it being
then allowed to rest for a short time (say about half an hour), and being finally
rubbed with a linen rag.
This polish is adapted to be employed even by inexperienced persons, and, when
applied, is most durable, not being liable to exudation, when used for covering
5 coats of oil-paint of long standing, it, unlike the polishing mediums hitherto used,
will produce no cracks, so that it may safely be applied to wooden articles painted

page_text: or polished long before, and will always prove durable and of satisfactory
appearance.

An Improved Polishing Medium:
We, PAUL THEIL, of 1 Friedrichshagener Strasse, Köpenick, Joiner, and
KARL SCHIMITZEK, of 14 Muggelsheimerstrasse, Köpenick, in the Empire of
Germany, Brush Manufacturer, 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:→
"s
In polishing articles of wood it has hitherto been usual first to rub them with
oil and smooth them with pumice-stone, and then to coat or rub them with a
comparatively weak alcoholic solution of shellac, thus imparting brilliancy to the'
surface to be polished. This first or initial polish was generally followed by a
second one, which was performed with a stronger-solution of shellac; and finally
a coating of spirits of wine and one of an alcoholic solution of benzoin or gum-
benjamin was applied, if necessary.

Polish of this kind has been found, however, to possess the serious disadvantage,
that it was liable to become dull in a very short time through rapid. exudation.
Again, it has been observed that surfaces painted some. time back, especially if
painted with oil-paint, are apt very soon to show cracks, a fact most probably
ascribable to the circumstance that the polishes above referred to are readily
permeated by the oil contained in the paint; the consequence being that
the paint, underlying the polish, having given off its oil, dries up, and, by
contracting, causes the external polish to break. It has therefore been deemed
necessary, before proceeding to polish wooden articles painted with oil-paint, to
remove therefrom as completely as practicable the old coating of paint.
The object of this invention is to avoid these inconveniences, and such object, is
accomplished by employing a polishing medium impermeable to oil or fatty bodies
and consequently allowing of no exudation.
The trials to which various descriptions of resin have been subjected for this
purpose, have shown that the resin of the guaiacum tree or lignum vitæ is best
calculated to impart the desired properties to the polish. Polish prepared with
this resin, being impermeable to oil, is not liable to exudation, and, probably for
this reason, the polishing process itself is greatly facilitated, one coat of polish
being generally sufficient to produce a satisfactory result.
Guaiacum polish prepared by mixing the following substances in or about in the
proportions named, has been found to answer the purpose very well
3 litres of spirits of wine (at 94 % rectified);
125 grammes of resin of guaiacum ;

,, resin of (preferably Sumatra) benzoin;

will produce no cracks, so that it may safely be applied to wooden articles painted
or polished long before and will always prove durable and of satisfactory

Having now particularly described and ascertained the nature of our said inven-
tion and in what manner the same is to be performed we declare that what we
claim is:-
First. A polishing medium in the preparation of which the resin of the
guaiacum, tree or lignum vitæ is employed.
Second. A polishing medium consisting essentially of an alcoholic. solution
containing guaiacum resin.
Third. The improved polishing medium consisting of an alcoholic solution
containing guaiacum resin, benzoin resin, shellac, linseed-oil, and benzine, in or
about in the above named proportions.
