PATENT OFFIC OSCAR LIEPMANN, OF BERLIN, GERMANY, ASSIGNOR TO M. MARTHA LIEPMANN, OF BERLIN, GERMANY.

MANUFACTURE OF VENEERED MOLDING OR THE LIKE.

SPECIFICATION forming part Of Letters Patent N0. 734,423, dated 3' u1y 21, 1903 Application filed November 14, 1902. Serial No. 131,446. (No model.) I

To all whom it may concern:

Be it known that I, OSCAR LIEPMANN, residing at Pfalzburgerstrasse 83, Berlin W., Empire of Germany, have invented certain new and useful Improvements in the Mannfacture of Veneered Moldings or the Like; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it pertains to make and use it, reference being had to the accompanying drawings, which form part of this specification.

The manufacture of moldings and the like for framing and other purposes presenting the appearanceof solid wood is ordinarily carried out by first preparing the moldings complete and then applying the wood veneer in well-known manner. This method of procedure is very expensive and requires much time, since the moldings must first be completely prepared-4'. e. provided with the ornamental and decorative portions and finished off.

According to my invention the veneering and the ornamentation or profiling is performed in one and the same operation, the veneers being applied to the mass or composition during or shortly subsequent to the production of the ornamentation.

The annexed drawing illustrates a machine which may be employdin carrying my invention into effect. The figure shows diagrammatically a vertical section of the essential parts of the apparatus.

a is the main cylinder or roller, in front of which the mass is deposited on the base by means of the funnel b and formed in the manner desired by the said cylinder a. Behind the latter is the band or strip of veneer c, which, with the aid of appropriate guiding means, is laid upon the masslying' upon the base and pressed or rubbed down into the surface of the molding by means of a suitable tool, here shown as a brush cl. The molding now reaches the cylinder e, which possesses a certain amount of resiliency, so as to exercise a slight pressure on the veneer. Finally the pressing-cylinder f is reached, whereby the strip or the like of veneer is subjected to final pressure.

. Should the surface to which the veneer is applied be a plane one, it willbe 'found' unnecessary to employ a brush cl or equivalent means. If, however, strips or the like of veneer are to be laid upon an ornamental surface, it is necessary to brush or otherwise press the strip down smoothly upon the curved or decorative surface. The strip will not be found to split or rend on application of subsequent pressure after such procedure, such as would be the case were heavy pressure applied at first.

Having thus described my invention, what I claim as new, and desire to secure by Letters Patent, is

The process of making veneer-m oldings consisting in applying a composition to a base and simultaneously applying to the upper surface of the composition a veneer strip, substantially as described.

In witness whereof I have hereunto signed my name, this 13th day of September, 1902, in the presence of two subscribingwitnesses.

OSCAR LIEPMANN.
