Improvements in the Manufacture of Paper adapted for being
Written or Drawn upon by Means of a Metal Style, and for
Polishing and Cleaning Metals.
I, LOUIS CAPAZZA, of 32, Rue Plétinck, Brussels, in the Kingdom of Belgium,
Aëronaut, do hereby declare the nature of this invention to be as follows :-
This invention relates to a paper which can be written or drawn upon by a style
made of any metal.
My invention consists in the means employed for obtaining this result and in-the
product resulting from the manufacture.
Some time ago when I conceived the idea of making aërial explorations by means
of balloons without aëronauts I was led to search for means of obtaining diagrams
on special paper by means of a metallic style at elevations at which the freezing of
liquids is almost universal. I have discovered a method of manufacturing such
paper and it forms the subject of the present invention.
According to my invention I mix with the pulp of paper a quantity of any
carbonate or of any oxide. Or instead of mixing the carbonate or oxide with the
pulp I coat the surface of the paper by means of a bath containing a carbonate or
oxide. The paper may then be calendered or not as desired.
Paper prepared as above described may be used like any ordinary paper and it
can be written and drawn upon by means of any metal and I therefore designate
my paper "Panmetallophile."
My process is not affected by the quality of the paper treated.
I advantageously employ, as the substance to be mixed with the paper pulp or to
form the bath, oxide of zinc which is harmless and has been recommended as a
substitute for lead carbonate in painting.
In cases where it is desired to produce deep markings on the paper, it is only
necessary to dip the dried paper into spirit of turpentine.
In practice I find that the following proportions give good results :-
100 kilogrammes of paper pulp
40

,, the oxide or carbonate.
For an ordinary sizing bath of 100 litres 30% of the oxide or carbonate. That
is to say sufficient to produce a layer analogous to a layer of water colour. Any
proportion suffices provided that it forms on the surface of the paper a layer of
oxide or carbonate.
My process produces a paper which does away with the necessity for pencils and
ink which are replaced by a durable metallic style.
By dispensing with the pencil, which it is necessary to point, economy is effected
both in material and time by everybody, merchants, bankers, shorthand-writers,
reporters, draughtsmen, scholars, etc.

halfpenny has cost three times this amount when fully written upon with pen
and ink.

paper is adapted for polishing and cleaning metals.

Improvements in the Manufacture of Paper adapted for being
Written or Drawn upon by Means of a Metal Style, and for
Polishing and Cleaning Metals.
1, LOUIS CAPAZZA, of 32, Rue Plétinck, Brussels, in the Kingdom of Belgium,.
Aäronaut, 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 paper which can be written or drawn upon by a style
made of any metal.
My invention consists in the means employed for obtaining this result and in the
product resulting from the manufacture.
Some time ago when I conceived the idea of making aërial explorations by
means of balloons without aëronauts I was led to search for means of obtaining
diagrams on special paper by means of a metallic style at elevations at which
the freezing of liquids is almost universal. I have discovered a method of
manufacturing such paper and it forms the subject of the present invention.
According to my invention I mix with the pulp of paper a quantity of any carbonate
or of any oxide. Or instead of mixing the carbonate or oxide with the pulp
I coat the surface of the paper by means of a bath containing a carbonate or oxide.
The paper may then be calendered or not as desired.
Paper prepared as above described may be used like any ordinary paper and it can
be written and drawn upon by means of any metal and I therefore designate my
paper "Panmetallophile."
My process is not affected by the quality of the paper treated.
I advantageously employ, as the substance to be mixed with the paper pulp or
to form the bath, oxide of zinc which is harmless and has been recommended as a
substitute for lead carbonate in painting.
In cases where it is desired to produce deep markings on the paper, it is only
necessary to dip the dried paper into spirit of turpentine.
In practice I find that the following proportions give good results :-

the oxide or carbonate.
For an ordinary sizing bath of 100 litres 30% of the oxide or carbonate.
That is to say sufficient to produce a layer analogous to a layer of water colour.
Any proportion suffices provided that it forms on the surface of the paper a layer
of oxide or carbonate.
My process produces a paper which does away with the necessity for pencils and
ink which are replaced by a durable metallic style.
By dispensing with the pencil, which it is necessary to point, economy is effected
both in material and time by everybody, merchants, bankers, shorthand-writers,
⚫ reporters, draughtsmen, scholars, etc.

page_text: By dispensing with pens and with ink, into which it is necessary to continually
dip the pens, the same economy is effected.
Moreover, by using my paper and style uncleanliness, etc. is avoided on the part
of scholars.
It is not necessary to insist on the fact that economy is effected by my
invention if it is borne in mind that an ordinary copy book costing one
halfpenny has cost three times this amount when fully written upon with pen
and ink.
The lines made by the style on my improved paper are unchangeable and my
paper is adapted for polishing and cleaning metals."
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 1
claim is :-
1. A process for manufacturing paper adapted for being written or drawn upon
by a style of any metal, such process consisting in mixing with the pulp of
ordinary paper a quantity of an oxide or of a carbonate substantially as
described.
2. A process for manufacturing paper adapted for being written or drawn upon
by a style of any metal, such process consisting in mixing with an ordinary sizing
bath a quantity of an oxide or of a carbonate substantially as described.
3. Paper, for being written or drawn upon by a metal style and for polishing
and cleaning metals, manufactured as hereinbefore described.
