A Process and Machine for Ornamenting Solid Wood or Veneers by
Means of Dies and Pressure.
I, Dr. MARCUS PINEL, of I. Fleischmarkt, 14, Vienna, Austria, Advocate, 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 process of and a machine for ornamenting solid wood
as well as veneers for furniture frames and panels and the like by means of dies
and pressure.
It consists in first impregnating the woods or veneers on the side to be ornamented
with a good solution of gelatine and borax with an addition of a greater or less
quantity of stearine, according to the hardness of the wood; after perfectly drying
the wood it is then passed between a heated pressing die consisting of a roller or
ring having engraved on it the matrix of the ornaments, and a stationary pressing
table, whereby the ornamental pattern of the roller or ring is impressed upon the
wood and thus effects its ornamentation. Gelatine and borax impart, great hard-
ness and density to the wood while the added stearine, as fatty material, produces
considerable toughness and imparts a fine lustre to the wood fibres.
The most suitable proportions for the above solution have been found to be
5 parts by weight of gelatine, 5 parts of stearine and 20 parts of borax, dissolved
in 70 parts of warm water, but I do not limit myself to these proportions as they
may be varied; thus good results are also obtained with an increase or a decrease
of the proportion of water and also, for hard woods the proportion of stearine is
advantageously increased relatively to those of the other ingredients.
The machine for carrying out the pressing process is shewn on the accompanying
drawing, in which Fig. 1 is a front view. Fig. 2 is a vertical cross section and
Fig. 3 is a part plan view, partly in section of the machine, Fig. 4 is a plan view,
and Fig. 5 a cross section on the line I-I Fig. 4 of the pressing table. Fig. 6
is an underneath plan, and, Fig. 7 a section of the same on the line II-II of
ig. 6, Fig. 8 is a detail of the abutment piece of the table in front and side view
and cross section. Figures 9, 10 and 11 shew elevations and section of the lateral
guide tables and guides. The machine consists of an upright or standard a upon
which a support c can be made to slide vertically in guides a¹ by means of a screw
spindle b, which support serves for carrying the guide tables.
The support is formed with an opening and in this opening a bracket dis
fixed to the standard for carrying the pivot c¹ supporting the pressing table, which
may be adjusted to any angle in respect to the standard a so that both the pressing
table and the support together with its parts may be adjusted to any required
position.
The pressing table consists of a support e pivoted by an eye c¹ in a bracket d,
and on which is mounted a plate or table e adjustable thereon by means of longi-
tudinal slots and setting screws e Figs. 4 to 6. This table carries a plate g
having a straight or curved ledge g along the upper end, which ledge together

page_text: with the table et serves as abutment for the wood to be ornamented by pressure.
The table et has an opening through which passes a bolt fi fixed to plate g, and
whose lower enlarged end has a threaded hole through which screws the screw
spindle carried by the support e, so that by turning this spindle the plate g can
be adjusted on the table et.
The support e is connected by a ball and socket joint at h¹ to a screw spindle h
that screws through a nut k carried in pivots on the standard a; this spindle h
consequently supports the entire pressing table e e f g.
By screwing the spindle h forward or backward through the nut k the table can
be made to assume a greater or less inclination to the standard a, such angle being
determined by the form of the wood block to be operated upon. According to the
variation of such angular position the angular position of the spindle h will also
be varied in turning the nut k on its pivots. Above the pressing table is arranged
in the known manner the pressing die roller or ring i which carries the intaglio
or die of the design to be produced. On each side of the pressing table is
arranged a support table; it consists of two similar parts carried by lateral ex-
tensions of the support c.
Each such part consists of a bracket horizontally adjustable on the plate c
and having horizontal top plates on which are mounted angular guides m Figs. 1,
9, 10, 11 which are held in any angular position on the plates 1 by means of are
shaped pieces n, the centres of which coincide with the outer apex of the angular
guides m resting on the plates l¹.
The pieces n have concentric slots n¹ through which passes a nipping screw o o
passing through a slot q in bracket and serving to secure the pieces n and
guides m in whatever position they are adjusted to.
One of the arcs n is attached to each end of the angular guide m in the latter
are laid flat bars p secured to m by screws m¹ passing through slotted holes pl
in the guides m so that these can be adjusted longitudinally.
By means of this arrangement the bars can be pushed close up to the table et
whereby the wood to be worked is securely guided both close up to the point where
it is acted upon by the die as also beyond that point.
As, in consequence of the varying thickness and form of the wood to be orna-
mented, the table e e will require to be inclined to a greater or less degree in
order to bring the part of the wood to be acted upon immediately below the die
of the pressing ring, the relative position of the guides must be capable of accurate
adjustment, and this is provided for by the said slotted ares and their slotted con-
nection to the brackets 1, as indicated by the different positions at Figs. 10
and 11.
When pressing thin pieces of wood, it may readily happen that they endeavour
to spread sideways under the pressure; for preventing this there is provided on
the top of the table et a small abutment piece u Figs. 2 and 8 which is guided by
a dovetail and groove u¹ on the under side of the table e and which can be moved
to and from the wood by means of a screw spindle v. This support projects over
the top side of the table and can be brought to bear against the edge of the wood
so as to effectually hold this in position against the plate g at the point where it
is subject to the pressure of the die.
It will be seen that by the above described appliances a very accurate guiding
and holding of the wood and adjustment of the working parts is insured, resulting
in a very accurate and perfect impression of the dies upon the wood.
ascertained the nature of this
Having now particularly described and
invention, and in what manner the same is to be performed, I declare that what
I claim is: :-
1. Process for producing solid wood or veneers with relief or intaglio ornamenta
tion produced by dies and pressure, which consists in impregnating the wood o
veneer on the side which is to be ornamented with a solution of gelatine and
borax to which is added a greater or less quantity of stearine according to the

page_text: nature of the wood, and after the wood is dry, subjecting it to the pressure of
ornamenting dies, substantially as described.
2. In a machine for ornamenting wood and veneers by means of dies and
pressure, the combination of a table support e carried by a screw spindle h and
pivotted screw nut k, whereby the pressing table can be adjusted to any required
angle, a table et adjustably mounted on the support e by means of guide slots ²
and screws e, and a plate g mounted on the table e, adjustable by means of a
screw spindle f, and having a raised ledge gl for receiving the wood to be operated
upon, substantially as described with reference to the drawing.
3. In a machine for ornamenting wood such as is referred to in the second
claim, the combination with the table et of an abutment piece u, adjusted by a
screw spindle for securing the wood in position and supporting it against lateral
spreading under the pressure, substantially as described.
4. In a machine for ornamenting wood such as is referred to in the second claim,
the combination with the support e and pressing table e of lateral guiding
devices for the wood consisting of tables carrying angular guides m m for the
wood which guides can be set to any required angular position by means of
slotted arc-shaped pieces n screws o and slots q in the brackets of tables 1, the
angular guides m being provided with longitudinally adjustable bars p secured
thereto by screws and slots p¹ and serving to support the wood on each side of
the pressing table et while being operated upon by the die, substantially as
described.
5. A machine for ornamenting wood by dies and pressure combined and operat-
ing as herein described with reference to the drawing.
