PROCESS OF MANUFACTURING ORNAMENTED VENEERS.

SPECIFICATION forming part of Letters Patent No. 425,233, dated April 8, 1890.

Application filed January 10, 1890. Serial No. 336,584, (No model.)

To aZZ whom it may concern.-

Be it known that I, LQUIS LING, of Berlin, in the Kingdom of Prussia and German Empire, have invented a new and useful Process of Manufacturing Ornamented Veneers, of which the following is a specification, reference being had to the accompanying drawing, forming a part of this specification,the figure shown being a partial plan view of a veneer constructed in accordance with my invention.

My invention relates to improvement in producing fancy -figured wooden plates. Although figured wood pictures or ornamented wood surfaces have been employed 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 surfaces of the colored veneer were not of a vivid color and the ornamented plates scarcely resembled the most ordinary ones out in wood, as after burning the shadings looked quite unnatural.

Thisinvention has been designed to impart a more artistic appearance to the hitherto somewhat monotonous pictures bymeans of better stamping, and by suitable mechanical means 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 the ornaments, may have a good effect; and the means employed are to burn portraits and figures, &c., in the veneer and to beautify them with gold or other metal without afterward having to go over the work by hand. The method of producing such figured wood pictures is as follows:

After the picture has been burned 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-leaf scratched off or removed with a stiff brush, so that only the outlines remain covered with foil, which outlines are fixed by means of the printing of the engraved plate. At the same time 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 onto the imprinted picture. In order to give a plastic appearance to the burned figure of the design, the nearly-finished picture is placed on 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 w1thout losing its plastic form. In the accompanying drawing those parts which are to be made prominent with gold or other metal are drawn.

What I claim, and desire to secure by Letters Patent of the United States, is-

The process herein described of manufacturing ornamented wood veneers, consisting in burning the desired picture or design in the face of the veneer, coating the back of the veneer with gum, as shellac, and its face with wax, drying the veneer, coating its face with a thin aqueous solution of the white of eggs, coating the face of the veneer with metal foil, subjecting the veneer to mechanical pressure under a moderately-heated die bear ing the design or picture on the veneer, and subjecting the veneer to mechanical pressure between said die and a corresponding punch, substantially set forth.

ln-witness whereof I have hereunto set my hand in presence of two witness s.
