Improvements in the Method Employed for Producing Ornamented
Wood Plates or Surfaces.
I Louis LING, Engraver of 8 Urbanstrasse Berlin in the Kingdom of Prussia and
German Empire 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 :-
Although figured wood pictures or ornamented wood surfaces have been established
for some time in many branches of industry hitherto they have not been suitable for
the better class of fancy articles or furniture as the services of one coloured veneer
were not of a vivid colour and the ornamented plates scarcely resembled the most
ordinary ones cut in wood as after burning the shadings looked quite unnatural.
Now this invention has been designed to impart a more artistic appearance to
these hitherto somewhat monotonous pictures by means of better stamping and
therefore in some mechanical way to provide the figured pictures with gold outlines
and then to press the figures and other ornaments in such a way that the expression
of the face and other parts of the body as well as the ornaments may have a good
effect and the means employed are to burn portraits and figures etc. and to beautify
them with gold or other metal without afterwards having to go over the work by
hand.
The method of producing such figured wood pictures is as follows:-After the
picture has been burnt into the veneer by means of an engraved plate a thin coat of
wax is laid on the upper surface of the veneer and the back has a coating of shellac
or other suitable gum. The veneer is then allowed to dry for a few hours then a
light covering of thin white of egg is laid on the upper (front) side and gold leaf
or other suitable metal foil spread over the whole surface. After the plate has been
spread over with the gold ornamentation it must be pressed at a moderate heat and finally
the superfluous gold loaf scratched off or removed with a sharp brush so that only
the outlines remain covered with foil which outlines are designed (fixed) by means of
the printing of the engraved plate. At the same timo the wax that has been laid on
does not stick to the metal foil on the upper surface it melts by pressure without
injuring the surface. The gold leaf must be as much larger as the contraction of
the veneer amounts to by burning so that the outlines press on to the imprinted
picture. In order to give a plastic appearance to the burnt figure of the design the
nearly finished picture is placed with a deeply engraved plate and is then pressed at
a light heat and strong pressure by means of a corresponding punch. The simple
(plain) veneer receives the plastic stamping and is then glued to stronger woods
without losing its plastic form. In the accompanying drawing those part which are
to be made prominent with gold or other metal are drawn more strongly than the
other parts.
Having now particularly described and ascertained the nature of my said inven-
tion and in what manner the same is to be performed I declare that what I
claim is
The method of producing figured wood pictures which consists in the veneer being
coated over on the back with shellac or other suitable gum and on the front with wax
the veneer is then dried for some time and after a thin solution of white of egg and
th cold ther

other suitable metal plate the plate is then embossed by means of a deeply engraved
plate and corresponding die.
