PROVISIONAL SPECIFICATION.
A Method or Process for Producing Pictures, Arabesques, and other
Decorations or Ornamentations on Wood.
We, ANTON SVEJKOVSKY of Prag-Smichov, Austrian Empire, Manufacturer, and
HERMANN STUDTE of Charlottenburg near Berlin, German Empire Engineer do
hereby declare the nature of this invention to be as follows:-
This invention relates to a method or process of producing pictures, arabesques, and
other decorations or ornamentations upon wood of any degree of hardness, by means
of pressure. This is effected as follows
:-
Beams of say about 100 to 150 millimeters thickness are cut to size with the aid of
a saw and are thoroughly dried; the dried beams are then with the aid of an
accurately working circular saw cut across or in the direction of their width into
pieces such as are required for the production of the ornamentations. By this means
plates are obtained which show the wood endwise or cut across the grain with the
surface that is to be provided with the ornamentation.
The surface should be cut with the circular saw as smooth as if they had been
planed in the smoothest possible manner.
The plates thus obtained are placed in a press containing two moulding plates, the
lower moulding plate being provided with a matrix, in relief, of the decoration to be
produced whilst the upper moulding plate is smooth; the wooden plate is laid with one
surface upon the lower die, and the upper moulding plate is placed above it, and then
the whole is subjected to as great a pressure as possible, say from about 200 to 300
atmospheres.
Plates treated in this manner show the desired ornamentations with the required
sharpness and have when compared with decorations produced by carving, an appear-
ance which is more pleasing and corresponds better with the original. They are also
more durable.
These very striking advantages, as compared with carved work, are not due to the
fact that in consequence of the very high pressure employed the very hardest woods
can be utilized in this process, but solely to the fact that the decorations are produced
only upon a surface of the wood, that is at right angles or across the grain and which
cannot in practice be produced by carving the ornamentations, and which was not used
in the method heretofore employed for the production of ornamentations by means of
pressure, according to which the wood pressed lengthwise or along the grain, was
previously subjected to a special chemical treatment.
The essential feature for the production of ornamentations according to this inven-
tion is that the wooden plates cut and fitting accurately on one another are not pressed
lengthwise of the grain but end wise or across the grain of the wood, just as if the
beam was placed upright and it were pressed end wise or against the grain. Before
the plates are placed in the press they may be coated with any desired paint or colour
dissolved in oil; the coloured oil at once penetrates the wood. This impregnation
however only serves to impart the desired colour to the product and has therefore no
influence upon the easy production of the ornamentation by pressure. The present
process may be employed for producing ornaments for cornices, ceilings, clock cases,
and so forth, and even for the production of entire pictures; thus the picture entitled
"The Last Supper," in which there are thirteen persons grouped together, has been
transferred on wood according to the process herein before described and a picture
thus which produced when provided with a dark coloured frame forms a very good
ornament for a room and church.

page_text: The chief advantages of the process hereinbefore described as compared with
carved work and pressed work as heretofore produced consists in the speed of pro-
duction, cheapness of manufacture, and appearance of produce. The cost of manu-
facture by this improved process is '70 per cent. cheaper than that of wood carving in
which thoroughly sharp work cannot be obtained.
Also according to the present invention wood only is used which has not been
subjected to a previous treatment as for example to chemical action.

COMPLETE SPECIFICATION.
A Method or Process for Producing Pictures, Arabesques, and other
Decorations or Ornamentations on Wood.
We, ANTON SVEJKOVSKY of Prag-Smichov, Austrian Empire, Manufacturer, and
HERMANN STUDTE of Charlottenburg, near Berlin, German Empire, Engineer, 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:-
This invention relates to a method or process of producing pictures, arabesques, and
other decorations or ornamentations upon wood of any degree of hardness, by means
of pressure. This is effected as follows:-
Beams or lengths of wood of say about 100 to 150 millimetres thickness are cut to
the required size by a saw and thoroughly dried; the dried beams or lengths of wood
are then, with the aid of an accurately working circular saw, cut across or in the
direction of their width into pieces of suitable thickness such as are required for the
production thereou of the ornamentations. By this means plates or pieces of wood are
obtained the surface of which that is to be decorated or ornamented is at. right angles
to or across the grain of the wood. The surfaces should be cut with the circular saw
as smooth as if they had been planed in the smoothest possible manner.
The plates or pieces of wood thus obtained are placed in a press containing two
moulding plates, the lower of which is provided with a matrix of the decoration to be
produced in relief, whilst the upper moulding plate is suiooth; the plate or piece of
wood is laid with one surface upon the lower matrix or die, and the upper moulding
plate is placed above it, and then the whole is subjected to as great a pressure as
possible, say from about 200 to 300. atmospheres.
Plates or pieces of wood thus treated show the desired decorations or ornamenta-
tions with the required sharpness, and have when compared with decorations or
ornamentations produced by carving an appearance which is more pleasing and
corresponds better with the original. They are also more durable.
These very striking advantages as compared with carved work, are not due to the
fact that in consequence of the very high pressure employed the very hardest woods
can be utilized in this process, but solely to the fact that the decorations or
ornamentations are produced only upon a surface of the wood, that is at right angles
to or across the grain, which cannot in practice be done by carving the ornamentations,
and which was not done in the method heretofore employed for the productien of
ornamentations by means of pressure according to which the wood was pressed
lengthwise or along the grain, and was previously subjected to a special chemical
treatment.
The essential feature for the production of ornamentations according to, this
invention is that the plates or pieces of wood cut and fitting accurately on one another,
are not pressed lengthwise of or parallel to the grain but end wise of or against the

page_text: grain of the wood, just as if the beam or length of wood were placed upright and it
were pressed endwise or against the grain. Before the plates or pieces of wood are
placed in the press they may be coated with any desired paint or colour dissolved in
oil, which at once penetrates the wood. This impregnation however only serves to
impart the desired colour to the product and has therefore no influence upon the easy
production of the ornamentation by pressure. The present process may be employed
for producing in wood, ornaments intended for cornices, ceilings, clock cases, and so
forth, and even for the production of entire pictures; thus the picture entitled "The
Last Supper," in which there are thirteen persons grouped together, has been trans-
ferred on wood according to the process hereinbefore described and a picture thus
produced which then provided with a dark coloured frame forms a very good ornament
for a room or Church.
The chief advantages of the process hereinbefore described as compared with
carved work, and pressed work as heretofore produced, consists in the speed of
production cheapness of manufacture and appearance of the product. The cost of
manufacture by my improved process is 70 per cent. cheaper than that of wood
carving in which thoroughly sharp work cannot be obtained.
In carrying out the present invention wood only is used which has not been
previously subjected to a preparatory treatment as for example to chemical action.
Having now particularly described and ascertained the nature of the said inven-
tion and in what manner the same is to be performed, I declare that what I
claim is :-
A method or process of producing pictures, arabesques or other decorations or
ornamentations on wood by means of pressure, in which the plates or pieces of wood
to be ornamented are first cut from a beam or length of wood in such a manner that
the surface of the wood to be decorated or ornamented is at right angles to or across
the grain of the wood, and are then placed in a press between two moulding plates
one of which is provided with a matrix the form of which corresponds with the
decoration to be produced in relief.
