I FRANZ PODANY of 114 Hernals Hauptstrasse in the City of Vienna and
Austrian Empire, Manufacturer of Wooden Mosaic Work do hereby declare the
nature of my Invention for IMPROVEMENTS IN ADJUSTABLE PLANES FOR PRO-
DUCING PARQUET FLOORING IN VARIOUS KINDS OF CURVILINEAR DESIGNS" and in
what manner the same is to be performed, to be particularly described and
ascertained in and by the following statement:--
My Invention relates to improvements in adjustable planes or implements for
producing parquet flooring in various kinds of curvilinear designs.
Figures 1 of the accompanying drawings represent the plane in elevation, top
view and cross section in normal position.
The plane or planing tool h consists of a number of single steel plates or
lamellas e e which are enclosed between the plates d d and are held together by
the screw 8.
The frames rr are provided with proper pressure screws so as to hold the plates
or lamellas e e absolutely immoveable.
A plate a is also employed which is fitted to one of the plates & and prevents
the lamellas e e from being pushed upwards.
These thin steel plates or lamellas ee can be employed in any desired number
according to requirements and are provided at both ends with suitable teeth z¹³
of which the teeth are arranged to stand about 1 to 2 millimetres in
advance or to the rear of the teeth 13 when a horizontal line B is drawn from
one toothing to the other in Figure 1.
A portion or part ff of the ends of the lamellas is left standing åbove and
below the toothing but the same do not protrude or stand so high as the toothing.
These projections ff serve as guides for the toothing after the same have once
penetrated the wood. The plates d d are shorter than the plates or lamellas e e
but are of like width with the same. The corners of the steel plates or lamellas e e
and the plates d d are recessed or cut away at c so as to be able to readily adjust
the said steel plates or lamellas in their normal position.
In normal position as shown in Figure 1 of the accompanying drawing the teeth
at both ends of the plane stand perfectly parallel.

page_text: When operating with my said plane or planing tool I have found it advantageous
to arrange the steel plates or lamellas so that the teeth ¹ of the even numbered
plates or lamellas (2, 4, 6, 8, etc) stand somewhat in advance of or to the rear of
the teeth of the plates or lamellas with uneven numbers (1, 3, 5, 7, etc) i.e. the
points of the various teeth form a zigzag line when seen from the surface.
My said improved plane or planing tool can be reciprocated by means of a
suitable motor and can be guided by means of the dovetail g or in other suitable
manner,
The stroke of the machine is made to correspond with the height of the block to
be operated on.
In order to prepare my said plane or planing tool so as to be able to put the
same in operation a guage is made of the curve, curves or design to be cut, all the
screws are loosened and the plane or planing tool brought so in contact with the
guage that the ends of the single steel plates or lamellas accomodate themselves to
the form of, the said guage-As soon as the said plates or lamellas have assumed
the same form as the guage (Figure 2) the screws which runs through the slots b
in the steel plates or lamellas and through the enclosing plates d d, is tightened up
and the frames rr adjusted so far towards the ends of the plane as possible or as
far as the form of the guage allows and the screws tightened up, care being taken
that the said frames are perfectly equidistant from the centre of the said plane.
The single plates or lamellas must as a matter of course be of perfectly like
thickness.
The plane or planing tool or cutting implement is now connected to the pitman
or in other manner with a suitable part of the motor, and the wood to be cut fed
to both ends of the said plane or planing tool.
In consequence of the steel plates or lamellas being of perfectly equal length one
end of the said plane will form the matrix or female, the other the patrix or male
part of the design in the guage employed.
The feed is effected on a suitable table through which the plane works and the
wood to be operated on can be held by suitable clamps or can be clamped to
moveable and adjustable standards or held in other appropriate manner.
As the parts of parquet flooring are symmetrical in form it is only necessary to
cut out a desired number of the parts of which the parquet is formed fit these
parts together and cut the single squares of parquet from the combined block
(Figure 3).
Having now particularly described and ascertained the nature of my said
invention and in what manner the same is to be performed I declare that what
I claim is
A design plane or planing tool consisting of a series of steel plates or lamallas
which are provided at each end with suitable teeth for simultaneously cutting out
the matrix or female and patrix or male. part of any figure or design to which the
single plates or lamellas had been adjusted by means of a suitable guage substan-
tially as described and shown.
