PROVISIONAL SPECIFICATION.
An Improved Method and Apparatus for the Manufacture of
Stencils.
I, EUGENIO DE ZUCCATO, of 15 Charterhouse Street, in the City of London,
Manufacturer, do hereby declare the nature of this invention to be as follows:-
My invention relates to an improved method of and apparatus for the manufacture
of stencils, and has for its object the provision of a cheap and simple fitting or
attachment, which is advantageously applicable to type-writing machines, for
example, whereby they are applicable for the production of stencil sheets or sheets
of perforated material such as are well known in connection with Zuccato's
Trypograph."
According to my invention I wind or otherwise place fine wire, twisted, stranded,
or plaited and packed closely, upon the periphery of the roller or other support
against which the paper or other sheet rests when it receives the impact of the type
or punch, so that the said sheet is supported upon a large number of small ridges
formed by the convolutions of the said fine twisted, stranded or plaited wire. The
said wire is secured permanently upon the cylinder or other surface, by brazing,
soldering, or otherwise.
When the apparatus is used for the manufacture of stencils the sheet is sharply
struck by a metallic type or a punch and forced against the said convolutions and
perforated by them with a series of minute perforations at the parts of the sheet
upon which the face of the said type or punch bears, so that groups of such
perforations in the form of letters or characters may be readily formed as desired
in the sheet, which is thereafter ready for use as a stencil sheet.
I prefer to employ for the said stencil sheets, paper suitably prepared with wax,
stearine, paraffin, or varnish or otherwise rendered impermeable to the oily ink or
other moisture which is employed upon them when they are, used for stencilling.
Instead of twisted or plaited wire I may employ fine wire of the kind used in
certain stringed musical instruments and obtained by winding one or more wires
upon another wire which forms a core. The wires employed according to my
invention may be of any suitable material and of any suitable cross section, but I
prefer to employ wires of cast-steel or of such other material as may be tempered
and hardened.
The winding of adjacent lengths of wire may be varied if desired, so that the
convolutions thereof may not be parallel.

COMPLETE SPECIFICATION.
An Improved Method and Apparatus for the Manufacture of
Stencils.
I, EUGENIO DE ZUCCATO, of 15 Charterhouse Street, in the City of London,
Manufacturer, 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 :-
My invention relates to an improved method and apparatus for the manufacture
of stencils and has for its object the provision of a cheap and simple fitting or
attachment which is advantageously applicable to type-writing machines, for
example, whereby they can be employed for the production of stencil sheets or

page_text: sheets of perforated material, such as are well known in connection with Zuccato's
Trypograph.'
According to my invention I wind or otherwise place fine twisted, stranded, or
plaited wire, packed closely, upon the periphery of the roller, platen, or other
support, in a machine or apparatus such as, for instance, a type-writing machine.
Against the wire thus placed the paper or other sheet rests when it receives the
impact of the type or punch, so that the said sheet is supported upon a large number
of small ridges formed by the convolutions of the said fine twisted, stranded, or
plaited wire.
When the apparatus is used for the manufacture of stencils the sheet is sharply
struck, by a metal or other hard type, or a punch, and forced against the said
convolutions and perforated by them with a series of minute perforations at the
parts of the sheet upon which the face of the said type or punch bears, so that
groups of such perforations in the form of letters or characters may be readily
formed, as desired, in the sheet, which is thereafter ready for use as a stencil sheet.
In certain cases I provide a shield of suitable material to be placed against the
paper which is to form the stencil, so that the type or punches may be cushioned,
to a certain extent, and not injured as they might be if they came too closely into
contact with the hard wire. An extra sheet of paper, or the tape of a type-writing
machine may be employed as the before-mentioned shield.
I prefer to employ for the said stencil sheets, paper suitably prepared with wax,
stearine, paraffin, varnish, or otherwise rendered impermeable to the oily ink or to
moisture which is employed upon them when they are used for stencilling.
Instead of twisted or plaited wire I may employ fine wire of the kind used in
certain stringed musical instruments and obtained by winding one or more wires
upon another wire which forms a core. The said wires may be of any suitable
material and of any suitable cross section, but I prefer to employ wires of cast-steel
or of such other material as may be secured in place by brazing or soldering, and
tempered and hardened.
The winding of adjacent lengths of wire may be varied if desired, so that the
convolutions thereof may not be parallel.
In the accompanying drawings,
Figure 1 is an elevation of a portion of a metal plate upon which is soldered a
winding formed by twisting two wires A and B together; a portion only of the
wire winding is shown.
Figure 2 is an elevation of a similar plate upon which a winding, consisting of a
wire B coiled upon an untwisted wire A, is secured.
Figure 3 is an elevation similar to Figure 1, but with two twisted wires, one
right-handed and the other left-handed, wound thereon in parallel coils.
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 I do not
claim the use of woven wire sheet, nor do I claim the use of parallel plain wires, for
the purpose specified, but what, I claim is
:―
1. A device for use in the manufacture of stencils, consisting of a support for the
material operated upon, faced with twisted wire, substantially as herein before
described for the purpose specified.
2. A device for use in the manufacture of stencils consisting of a support for the
material operated upon, faced with wire coiled upon a wire core, substantially as
herein before described for the purpose specified.
3. The wire facing for use, upon, a portion of a machine for the manufacture of
stencils, substantially as herein before, described with reference to, Figure 1, or.
Figure 2, or Figure 3, of the accompanying drawings, for the, purpose specified..
