An Improved Apparatus for Ornamenting Strips or Frames of
Wood and the like Material.
We, FRANZ ALOIS BRAUSIL, of 126 Mariahilferstrasse, Vienna, VII, Artistic
Joiner, CARL PAULITSCHKY, of 5 Kärntnerstrasse, Vienna I, Engineer and
MARIE HOLAUBEK, of 81 Burggasse, Vienna VII, of no occupation, all in the
Empire of Austria-Hungary, 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 an improved machine for ornamenting or decorating
lengths or strips as well as circular or oval pieces or frames of wood or the like
material by a simple pressing operation.
A machine of this kind is illustrated in the accompanying drawing, in which
Figure 1 is a side view.
Figure 2 a vertical transverse section and
Figure 3 a horizontal section thereof, the driving pulleys and the second
pedestal or standard being omitted.
Figure 4 is a side view,
Figure 5 a plan and
Figure 6 a view parallel with the face of the pressing table or guide roller and
showing a circular frame thereon in position to be ornamented.
Figure 7 is a plan, and
Figure 8 a side view of the table and guide roller and an oval frame placed in
position rendy for being pressed at its outer side, and
Figure 9 is a similar side elevation but showing the frame in a position ready
for being pressed at its inner side.
The apparatus substantially comprises two principal parts, viz.:
(1) The pressing roller or ring with its bearing and actuating mechanism and
(2) The lower guide roller and pressing table with adjusting device and feed
table, (the latter being only used when impressing longitudinal strips of wood or
the like).
In the top part of a frame formed by two properly stayed pedestals A (of which
only one is shown) is arranged a bearing a, adjustable by means of screw spindles a',
and the pressing roller shaft B, located in this bearing, carries upon its free
extremity the pressing roller or ring & provided with the intaglio or opposite of the
design to be pressed on the blank.
Below the pressing ring 6 (or pressing roller as the case may be) the pressing
table and guide roller are arranged so as to be adjustable according to the cross
sectional dimensions of the blank to be pressed, and also according to the place
where the design or pattern is to be pressed into the said blank. The guide roller
consists of a disc g, forming the edge of the roller, and a ring g' smaller in diameter
than the said dise; the blank to be impressed is guided and supported in the angle
formed by the said roller and disc while being impressed. This roller is rotatably
mounted upon a bolt m, and bears against a plate or table f, which, by means of a
swivel-joint c d is arranged on a supporting plate ec mounted on the pedestal A.
From the supporting plate c toward the plate fa curved arm h extends, and from
the plate another curved arm k extends toward the said supporting plate c, both
of which arms have the pivot d of the swivel joint as their common centre; these
arms are adjacent to one another and are each provided with longitudinal slots /¹

page_text: and respectively which are parallel to one another, and through both of which
passes a screw bolt i having a screw nut i¹.
This arrangement allows the plate to be adjusted to any required angle of
inclination relatively to the supporting plate c or to the pedestal A (according to
the shape and size of the blank to be pressed), after simply loosening the nut i¹,
the plate is turned about the hinge ed until it has reached the proper angle
of inclination, whereupon it is fixed in this position by screwing the aut tightly
upon the bolt and thereby forcing the two arms h and k together. The guide
roller g g may if desired, be made in one piece, instead of in two parts, as shown
in the drawing, the lower part consisting of a simple flat disc g, upon which the
second part having the shape of a ring g' is mounted upon a bolt m so as to be
rotatable about the latter independently of the disc g, and so that the cylindrical
peripheral surface of the said ring is perpendicular to the said disc g.
The outer peripheral surface of the ring together with that portion of the disc g
projecting beyond the said peripheral surface of the ring constitute the necessary
support for the blank to be pressed, irrespective of whether this blank be of
straight circular or oval (elliptical) shape.
The portions g g' are adjustable together with their bolt m in a slot f¹ of the.
plate and are consequently capable of being either approached toward the pressing
roller or removed therefrom, so that the blank to be pressed can be exactly adjusted.
relatively to the pressing ring b.
If frames are required to be pressed, the guide roller alone is sufficient, whereas
for pressing longitudinal blanks a feed table is required in addition. Such feed
table may be constructed in any suitable way, and the accompanying drawing
merely represents an example, according to which such feed table consists of a
carriage n capable of sliding upon guides n' n¹ of the pedestal A and vertically
adjustable by a screw bolt n³ and nut n; which carriage is at each side of the
pedestal A provided with suitable extending guide tables p p, upon each of which
a plate 9, 9 is arranged, adjustable longitudinally. Each table is also provided
with adjustable angular rails r r. During the pressing operation a special feeding
device for the blank is not required, since those parts of the pressing ring which
have been forced into the wooden blank will automatically move the latter forward
as the rotary motion proceeds. Lateral displacement need not be apprehended,
because the blank to be pressed is, owing to the pressure of the pressing ring,
continuously and firmly forced into the angular recess formed by the disc g and:
the ring gl.
Figures 1 to 3 represent the method of pressing longitudinal blanks, and
Figures 4 to 9 illustrate the operation of pressing circular, oval (elliptical) and
other curved blanks or frames.
When the sides of a frame blank are to be provided with ornaments by means.
of this pressing machine, the frame is so placed on the guide ring g', properly
adjusted to the required angle, that its rear surface will rest upon the portion g
projecting beyond the ring g', whilst the ring g' itself projects through the opening
of the frame and thus supports the latter at its inner side.
By the pressure of the pressing ring the frame is continuously forced into the
angular recess formed by the parts g and g', and is at the same time moved forward,
that is to say, rotated as the pressing operation proceeds, by the action of the
pressing ring whose ornamenting surface enters the blank.
In most cases however the frame blanks are required to be ornamented at the
inner front side as well as at the outer front side and when this internal ornamenta-
tion is to be effected by this machine, the frame must occupy an approximately
vertical position as compared with its position when being pressed on its outer
side.
In order that this position may be maintained, a longer shaft t is mounted
upon the bolt m of the pressing table, and upon this shaft t a rod s provided with
transverse arms is fixed by means of a double socket. During the pressing
operation the frame is, as illustrated in Figures 5 and 9, placed against the
transverse arms ss and against the ring g'; the pressing is then effected in

page_text: exactly the same manner as if a longitudinal blank were being pressed. The
adjustment of the frame takes place automatically, since in this case also, the said
frame is (this time at its exterior periphery) forced by the pressure of the pressing
ring into the angular recess formed by the parts g and g', and displacement thereby
prevented.
The movement of the frame is produced by the rotary motion of the pressing
and guide rollers, describing either a circle or other curve, and depending upon
the pressure and the simultaneous rotary motion of the pressing roller upon the
inside of the frame.
Owing to the fact that the annular portion g' of the guide roller is made
exchangeable, and the arms s¹ s' adjustable, both the outer and inner sides of
frames can be provided with ornamental impressions irrespective of the dimension
of their central opening and of the width of the frame.
Instead of causing the disc y to be rotated by friction alone, it may be actuated
by means of wheel or belt gear the rotary motion imparted being proportionate to
the rotation of the upper pressing roller. This latter method of feeding is of
great advantage in cases where comparatively hard and thick blanks are to be
impressed. For the purpose of obtaining clearer impressions upon the blanks, the
pressing ring and guide roller may be previously heated, and the wood or other
material may be subjected beforehand to a preparatory treatment of any suitable
kind, which need not however be described here, because such treatment is already
known and therefore does not lie within the scope of this invention.
Having now particularly described and ascertained the nature of our said inven-
tion and in what manner the same is to be performed, we declare that what we
claim is :-
corre-
1. An apparatus for providing longitudinal blanks and circular or oval blanks of
frames of wood or the like material with ornamental impressions; the essentia
features of the apparatus being a pressing roller located in adjustable bearings a,
and provided on its periphery with the design or pattern to be impressed on the
blank; or, instead of the pressing roller, a pressing ring & mounted on a
sponding roller, and guide disc g g arranged opposite such pressing roller or
ring and adjustable in height as well as in angular inclination, the said guide roller
presenting a supporting surface of angular cross-section, which surface is, by the
proper displacement or adjustment of the said guide disc g g', brought in such a
position relatively to the pressing ring or roller, that the surface of a blank or
frame to be impressed will occupy the exact position required for the impression.
2. A constructional form of the pressing apparatus referred to in the preceding
claiming clause, in which the guide roller consists of two parts, namely, of a disc g
arranged rotatably around an adjustable bolt m, and of a ring g' resting upon said
disc and likewise made rotatable around the said bolt in but independently of the
said disc g, the cylindrical peripheral surface of which ring g' stands perpendicularly
upon the disc g and forms together with the portion of the disc g projecting
beyond the ring g', the angular surface, serving as the support for the blank to be
impressed.
3. In apparatus, of the kind referred to in the first and second claiming clauses,
for providing blanks and frames of wood and the like material and more especially
the inner sides of such blanks or frames with ornamental impressions, a device for
guiding such blanks or frames, consisting of a rod s arranged on the prolonged
pivot-bolt m, this rod s having transverse arms s s', against which and against the
cylindrical ring g', the frame blank, to be impressed, is placed.
