Improvements in or relating to the Production of Multiple Pictures,
Representations, or Copies.
I, JAN SZCZEPANIK, of Ungargasse 12, Vienna III, Austria, Engineer, do
hereby declare the nature of this invention to be as follows:
--
The invention relates to a method of simultaneously producing as many
similar pictures or copies as may be desired, of or from a given object or combina-
tion of objects.
This method is based on the fact that when a plate provided with a number
of holes is placed between an objective and an image-receiving screen there
are projected upon the latter similar images of the object in or before the
objective to a number equal to that of the holes in the plate.
The method will now be described in detail with the aid of the accompanying
drawings, in which
Fig. 1 shows the arrangement of a projecting apparatus for carrying out the
method, whilst
Fig. 2 illustrates a portion of the perforated plate;
Figs. 3 and 4 represent two diaphragms, with the object of which a multiple
representation is to be made;
Fig. 5 shows several pictures or copies combined to form a pattern or orna-
ment.
In Fig. 1a indicates the objective of the projecting apparatus, 6 the diaphragm
inserted in it.
An opaque plate d, possessing suitably distributed holes (see Fig. 2), is
arranged between the objective and the image-receiving screen consisting by
way of example of a matt or ground glass disc c.
..
The figure or object of which a multiple representation is to be made may
be formed by the diaphragm opening itself or a transparent negative or
diapositive" of the object may be arranged in place of the diaphragm. On
illuminating, an image of the object appears on the matt or ground glass disc
for every hole in the plate; thus there are formed just as many copies of the
object as there are holes in the plate d.
If the object (at e) of which a multiple representation is to be made, is
arranged in front of the objective, the figure corresponding to the object appears
in each single image corresponding to the opening in the diaphragm.
"
"
If the openings in the plate d are near enough together, the diaphragm
images combine to form a pattern, design, or ornament, as is shown in Fig. 5.
The negatives or diapositives to be placed in the objective instead of the
screen may consist of paintings on glass plates. If a sensitive photographic
plate be used instead of the matt or ground glass disc, then from one object
and by a single impression, as many photographs of the object can be obtained
as there are holes in the plate, or a repeat or arrangement design or ornament
ig. 5) can be produced.

page_text: It is possible to produce by the method described photograms that can serve
different purposes, for example, for the production of prints as ground work for
documents, bonds, securities, etc., in so far as it is a question of multiplying or
forming patterns with repeating designs or figures. As these impressions depend
not only on the diaphragms, but also on the arrangement of the openings in
the perforated plate, imitation is almost impossible.

Improvements in or relating to the Production of Multiple Pictures,
Representations, or Copies.
I, JAN SZCZEPANIK, of Ungargasse 12, Vienna III, Austria, Engineer, 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 method of simultaneously producing as many
similar pictures or copies as may be desired, of a given object.
This method is based on the fact that when a plate provided with a number
of holes is placed between an objective and an image-receiving screen there
are projected upon the latter similar images of the object in the objective to
a number equal to that of the holes in the plate.
The method will now be described in detail with the aid of the drawings
filed with my Provisional Specification, in which
Fig. 1 shows the arrangement of a projecting apparatus for carrying out the
method, whilst
Fig. 2 illustrates a portion of the perforated plate;
Figs. 3 and 4 represent two diaphragms with the object of which a multiple
representation is to be made;
Fig. 5 shows several pictures or copies combined to form a pattern or orna-
ment.
In Fig. 1a indicates the objective of the projecting apparatus and the
diaphragm inserted in it, whilst the arrow marked e indicates a source of light.
An opaque plate d, possessing suitably distributed holes (see Fig. 2) is
arranged between the objective and the image-receiving screen consisting by
way of example of a matt or ground-glass disc c.
The figure or object of which a multiple representation is to be made may
be formed by the diaphragm-opening itself, or a transparent negative or
diapositive of the object may be arranged in place of the diaphragm. On
illuminating, an image of the object appears on the matt or ground-glass disc
for every hole in the plate; thus there are formed just as many copies of the
object as there are holes in the plate d.
If the openings in the plate à are near enough together, the diaphragm
images combine to form a pattern, design, or ornament, as is shown in Fig. 5.
The negatives or diapositives to be placed in the objective instead of the dia-
phragm may consist of paintings on glass plates. If a sensitive photographic
plate be used instead of the matt or ground-glass disc, then from one object
and by a single impression, as many photographs of the object can be obtained
as there are holes in the plate or a repeat design or ornament (Fig. 5) can be
produced.

page_text: It is possible to produce by the method described, photograms that can serve
different purposes, for example, for the production of prints as ground work for
documents, bonds, securities, etc., in so far as it is a question of multiplying or
forming patterns with repeat designs or figures. As these impressions depend
not only on the diaphragms, but also on the arrangement of the openings in
the perforated plate, imitation is almost impossible.
Having now particularly described and ascertained the nature of the said in-
vention and in what manner the same is to be performed I declare that what
I claim is:-
1. The production of multiple pictures, representations, or copies of a single
object by projecting on a screen an image of the object through each of a
number of holes in a plate d placed between the objective and the screen;
whether or not the images obtained are united into a repeating ornament and
whether or not a photographic plate is used as picture-receiving screen.
2. The production of multiple pictures, representations, or copies of a single
object as herein before described with reference to and illustrated in the draw-
ings filed with my Provisional Specification.
