PROVISIONAL SPECIFICATION.
Improvements in Producing Designs on Wood.
I FIDELIUS TSCHOFEN of Vienna in the Empire of Austria 8 Rother Hof,
First Lieutenant in the Imperial and Royal Austro-Hungarian Army do hereby
declare the nature of my invention to be as follows:-
This invention relates to a process for producing burnt designs on wood, said
process being so simple that very pretty burnt wood designs or text can be rapidly
produced even by inexperienced persons.
In order to carry my improved process into effect, negatives of the design or text
are produced in the following manner.
Pictures, designs text etc. are produced in well known manner by means of litho-
graphic or other printing a small quantity of viscid varnish or linseed oil being
preferably mixed with the ink. The fresh, damp printing is now powdered with
very finely pulverised permanganate of potassium to which a little chalk can be
added, said powder being applied by means of a wadding pad or its equivalent and
allowed to dry whereby the powder facilitates the drying.
If gum or glue is used in printing, the same are also powdered as aforedescribed.
For transferring or burning in the printed matter, the object to be printed is
preferably dampened and the prepared negative with the printed surface downwards
laid on and snugly pressed onto the same by means of a soft pad, rollers, brushes
or in other suitable manner.
The pictures, designs etc. can be retouched, the outlines redrawn, lights be
added, parts etched and so on in order to improve the appearance of the same.
The permanganate of potassium can if desired be added to the printing ink so as
to avoid the powdering process.
It is recommended to choose level smooth surfaces in the wood as far as this is
possible.

Improvements in Producing Designs on Wood.
I FIDELIUS TSCHOFEN of 8 Rother Hof Vienna in the Empire of Austria, Firs
Lieutenant in the Imperial and Royal Austro-Hungarian Army 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 for producing designs or the like on wood
the said process being so simple that designs or text may be rapidly produced even
by inexperienced persons.
In carrying my improved process into effect negatives of the design or text are
prepared in the following manner.
Pictures, designs or text are first. produced by lithographic or other printing or
in any well known manner a small quantity of viscid varnish or linseed oil being
preferably mixed with the ink and the negative is taken.
The fresh damp printing is now powdered with very finely pulverized per-
manganate of potassium to which a little chalk can be added the said powder being
applied by means of a wadding pad or its equivalent and allowed to dry.

page_text: It may be found convenient in some cases to add the permanganate of potassium
to the printing ink so as to avoid the powdering process. If gum or glue be used
in the printing such should be also powdered.
In transferring the printed matter the object on which the design is to be
reproduced is damped and the prepared negative with the printed surface down-
wards laid thereon and firmly and evenly pressed upon the same by means of a soft
pad, rollers or other suitable appliance.
The pictures, designs or text can be retouched, the outlines redrawn, lights added,
parts etched and so forth in order to improve the appearance and it is recommended
to select level and smooth surfaces in the wood on which the designs are to be
reproduced as far as is possible.
Having now particularly described and ascertained the nature of my said inven-
tion and in what manner the same is to be performed I declare that what I
claim is
1. The method of producing designs, pictures, text or the like upon the smooth
surfaces of woods substantially as hereinbefore described.
2. In reproducing designs, text or the like upon wooden or like vegetable surfaces
the addition of permanganate of potassium to the ink or other medium used in.
transferring such design to the negative by means of which the said design- is
reproduced upon the desired surface.
