Moulds, Borders, Reglets, and the like.
We, FRANZ KAMMANN, of Vienna-Neustadt, Austria, Gentleman, and FRANZ
JURSCHINA, of Hartmann-gasse 1, Vienna V, Austria, Sculptor, do hereby declare the
nature of this invention to be as follows:-
Attempts have often been made to substitute some other substance for the material
of which printing type is usually composed. But with few exceptions the ordinary
type-metal has had to be again resorted to, the substitutes tried being found too
expensive or their employment being attended with serious disadvantages.
For example, the use of glass type was soon abandoned, because it did not retain
the printing ink sufficiently, and the printing was consequently very often indistinct
and blurred.
Now according to this invention type, stereotype moulds, borders, reglets, and the
like are made of an artificial stone that is an excellent substitute for the materials
heretofore employed, as it can be readily moulded, is cheap, and is hard and yet
sufficiently elastic to bear great pressure without injury, whilst the type moulded from
it will readily take up, retain, and give off the ink.
This artificial stone is especially suitable for the manufacture of large type-letters,
borders, and the like, for printing wall-posters, as with it the letters can be made
much cheaper and they will be much more durable than those of wood heretofore
employed.
The manufacture of type, stereotype-moulds, borders, and the like in accordance
with this invention is carried out as follows:
Finely powdered silicic acids ("Kieselsäuren") of a greater or less degree of
purity are intimately mixed with a small quantity of hydraulic lime, fluid silicate of
soda ("Kieselsauras Natrium") is poured over the mixture and it is kneaded until it
becomes a uniform plastic mass which is then pressed into suitable moulds. Or the
mixture can be poured in a fluid state into the moulds.
When the mass has hardened it is taken out of the moulds and dried.

page_text: A New or Improved Manufacture of Printing Type, Stereotype
Moulds, Borders, Reglets, and the like.
We, FRANZ KAMMANN, of Wiener Neustadt, Austria, Gentleman, and FRANZ
JURSCHINA, of Hartmangasse 1, Vienna V, Austria, Sculptor, 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:-
Attempts have often been made to substitute some other substance for the material
of which printing type is usually composed. But with few exceptions the ordinary
type metal has had to be again resorted to, the substitutes tried being found too
expensive or their employment being attended with serious disadvantages.
For example, the use of glass type was soon abandoned, because it did not retain
the printing ink sufficiently, and the printing was consequently very often indistinct
and blurred.
Now, according to this invention type, stereotype plates, borders, reglets and
various other objects, in which very sharp outlines are required, are cast or pressed of
a self-hardening paste or artificial stone, which is an excellent substitute for the
materials heretofore employed in the manufacture of type, as the said paste can be
readily moulded, is cheap, and is hard and yet sufficiently elastic to bear great
pressure without injury, whilst the type moulded from it will readily take up, retain
and give off the ink.
This self-hardening paste or artificial stone is especially suitable for the manufacture
of large type-letters, borders and the like for printing wall-posters, as with it the
letters can be made much cheaper and they will be much more durable than those of
wood heretofore employed.
In order to prepare the said paste or artificial stone finely ground quartz (silica) is
moistened with an aqueous solution of water-glass (alkaline silicate of potassium or
sodium) and the whole is then thoroughly stirred up. According to the greater or
less proportion of solution of water glass which is added to a given quantity of quartz
powder, the resulting mass will be either semi-fluid, which can be poured into moulds,
or of a doughy consistency admitting of its being pressed into moulds.
If preferred the paste or artificial stone may be made less expensive by the addition
of hydraulic cement, which is incorporated with the quartz powder before the same is
moistened with the solution of water-glass. The hydraulic cement however is not an
essential ingredient of the paste or artificial stone, which, in either case, will soon
harden to a stony consistence.
As the said paste (especially when in the semi-fluid state) is particularly well
adapted to fill in the finest excavations in the moulds, and consequently to reproduce
any model with its most minute details, it is well adapted for the industrial multipli-
cation of small objects having ornamentations in relief. Moreover, the said paste
has the property of always remaining, porous and for this reason it well retains
printing ink.

page_text: Having now particularly described and ascertained the nature of our said
invention and in what manner the same is to be performed we declare that what
we claim is :-
-
1. The herein above described new or improved manufacture of printing type
stereotype moulds borders reglets and the like.
2. For casting or moulding printing type and other articles as aforesaid a self
hardening paste or artificial stone consisting of fine quartz powder, moistened and
stirred up with an aqueous solution of water-glass so as to form either a semi-fluid or
a doughy mass, substantially as described.
3. A self hardening paste or artificial stone for casting or moulding printing type,
or other articles as aforesaid consisting of a mixture of fine quartz powder and
hydraulic cement, moistened and stirred up with an aqueous solution of water-glass so
as to form either a semi-fluid or a doughy mass, substantially as described.
