Apparatus for Simultaneously Writing a Number of Identically
Similar Documents.
I, Camillo TschINKEL, of VIII Josefstädterstrasse 52, Vienna, in the Empire
of Austria, Imperial and Royal Austro-Hungarian Consul, do hereby declare the
nature of this invention to be as follows:-
This invention relates to apparatus designed to enable a number of sheets to be
written on at the same places simultaneously, and thus, to produce in one single
writing operation a number of identical documents.
In this apparatus the sheets which are to be written on at suitable places by
means of a multiple pen or of a multiple lead pencil, are passed over fixed
supporting bars, and between pairs of pressure rollers covered with elastic material "
and capable of being moved by means of ratchet mechanism so that the sheets
are drawn forward to an extent equal to the distance between the lines of writing.
The writing instrument comprises several pens or pencils attached to a support
which is arranged obliquely to the handle and which may be attached to the
handle either rigidly or pivotally, and which is rendered flexible by means of
compression springs or tension springs inserted between the handle and the
support, whereby a uniform bearing of all the pens or pencils upon the sheets
is produced.
An apparatus of this kind for simultaneously writing a number of identical
documents is illustrated in the accompanying drawings wherein Fig. 1 is a
vertical longitudinal section through the apparatus shewn in the position of use.
Fig. 2 is a side elevation of the apparatus in which some parts of the same are
shewn in the inoperative positions. Fig. 3 is a plan of the apparatus. Figs. 4,
5, and 6 illustrate three modifications of the multiple pen (in the present case
a triple pen). As shewn, in the box 1, there are transverse bars 2 equal in
number to the number of the identically similar documents that are to be pro-
duced. In the side walls of the box 1, or in plates 3 therein there are mounted
three pairs of rollers, 4, 5, 6, 7 and 8, 9 corresponding to the number of the
cross bars. Of these pairs of rollers, the first two pairs are arranged below the
cross bars 2, whilst the third pair of rollers 8, 9 are arranged behind the last
cross bar 2. The rollers of all the pairs are covered with elastic material, prefer-
ably caoutchouc, and they serve to grasp the sheets to be written on, and to
drawn them forward in a compulsory manner. The sheets 10 (indicated by
dash-dotted lines in Fig. 1) are inserted with their lower ends loosely into the
slot (situated in front of the cross bar) into the box. The upper end of the sheet
is passed over the corresponding cross bar 2 and is inserted into the slot situated
behind the latter in such a manner that the upper edge of the sheet will be
caught by the corresponding pair of rollers. This is facilitated by the fact that
guides 37 are attached to the lower side of the cross bars as shewn in Fig. 1.
The last sheet is inserted directly over the rear bar 2 between the corresponding
pair of rollers S, 9, which are arranged laterally of the said bar.

For the purpose of keeping the parts of the sheet that enter the inside of the
box well apart, round bent parallel metal plates 11 are provided between which
there are formed guide slots 12 for the sheets that move over the bars.
movement of the pairs of rollers is effected by means of a ratchet mechanism which
consists of a ratchet pawl 13 having a handle and a ratchet 14, upon the shaft of
which there is mounted a small toothed wheel 15 which is rigidly connected to
the roller 4 and which gears with a toothed wheel 16 of the same size that is
rigidly connected to the second roller 5. The transmission of the motion of
the ratchet mechanism to the other pairs of rollers is effected by means of the
toothed wheel 17 that is mounted on the ratchet wheel shaft, that is to say through
the medium of the intermediate wheels 18, 19, 20, 21 to the pair of rollers 6 and 7,
and from the wheel 19 through the medium of the intermediate wheels 22, 23, 24
and 25 to the last pair of rollers 8 and 9. The transmission is effected, as will
be seen from Fig. 2, in such a manner that the sheets will be carried along in the
same direction and with the same speed. On the outer end of the ratchet wheel
shaft there is mounted a crank handle 26 by means of which (after the permanent
disengagement of the ratchet pawl from the ratchet wheel) the pairs of rollers
The stroke of the
can be rotated at will in either one or the other direction.
ratchet pawl is limited by means of a stop 28 which is moveable and is adjustable
in a slotted arc-shaped piece 27. By shifting this stop, the stroke of the ratchet
pawl, and consequently the extent of the forward movement of the sheets, that is
to say the distance apart between the lines, can be varied as desired.
For the purpose of effecting an exact bearing of the sheets upon the surface
of the cross bars, there is provided a brake device which consists of a friction
roller 29 for each cross bar. The friction rollers are arranged in the slot situated
in front of the corresponding cross bars, and are each mounted in a rotary
manner in a common sliding bar 30 at both ends. The rearward extension of the
latter terminates in two pressure knobs 31 that project from the rear wall of the
box, and it is subject to the pressure of the flat springs 32 which have a tendency
to push the sliding bars 30 backwards. Below each of the two sliding bars 30
there is a spring pawl 33 fixed pivotally to the side wall of the box. This pawl is
caused by the forward movement of the sliding bar 30 produced by pressing the
knob 31, to engage over a conical lug 34 on the bar 30 and to keep the latter in
its position. A pin or knob 35 fixed on the side of the pawl 33, extends through
a slot 36 in the side wall of the box and it can be pressed down by hand in
opposition to the action of the spring, so as to disengage the sliding bar 30
which is pressed forward by the action of the spring 32. When both sliding
bars have been disengaged in this manner, all the friction rollers 29 bear against
the front surfaces of the corresponding cross bars with the result that the sheets of
paper which are situated between the cross bars and the friction rollers, are
gripped with a moderate pressure. By means of the friction thus produced the
sheets are maintained in tension so that they will lie flat upon the cross bars.
The pens or pencils used for writing comprise as many pens or pencils 38 as
there are cross bars 2. In the present case there are three of such pens 38 which
are fixed to a holder 40 that is arranged at a suitable angle to the handle 39.
In the arrangement shewn in Fig. 4 the holder 40 is rigidly connected to the
handle. In the multiple pen shewn in Fig. 5, the holder 40 is pivotally connected
at its middle to an extension 41 of the handle 39 substantially parallel to the
part 40, compression springs 43 being inserted at both ends between the parts 40
and 41. In the arrangement shewn in Fig. 6, the two arms 42 that form a
fork are fixed to the handle 39, and the holder is pivotally mounted in the ends
of said arms, a spiral spring 483 being inserted between the handle 39 and the
holder 40.
In writing the pen is placed upon those parts of the sheets of paper (that are
Whereas
clamped in the manner described) which pass over the cross bars.
writing with the rigid pen, Fig. 4. requires a greater skill, the two other pens can
be easily manipulated because by reason of the yielding connection of the

page_text: holder 40 with the handle of the pen, a constantly uniform bearing or pressure
of all the pens upon the sheets is ensured. In all cases the hand must however,
be well supported during writing and for this purpose there is provided at the
front of the box a sloping plate 44 which consists preferably of a number of parts
hinged together, and which is supported by means of side pins 45 in vertically
slotted guides 46 projecting in front of and attached to the side walls of the box.
In position of use as shewn in Fig. 1, the front edge of the plate 44 rests on the
table and the pins 45 are supported by the lower ends of the guides 46. When the
apparatus is out of use, the plate 44 can be folded together as shewn in Fig. 2
and over the whole apparatus as a cover. To the rear edge of the box there
is hinged an apparatus designed for blotting off the freshly written matter. This
apparatus consists of a hinged plate 47 which is raised by spring pressure and
upon which blotting paper 49 is stretched over an elastic underlay 48. This
blotting paper is fixed at one end in a slot in the plate and at its other end is
wound on a rotary clip 50 of any known kind. The plate 47 is connected by a
link 51 and lever 52 with a slotted lever 53 by depressing which the plate is
brought down so that the blotting paper can blot off the freshly written matter
on the sheets.

Apparatus for Simultaneously Writing a Number of Identically
Similar Documents.
I, CAMILLO TSCHINKEL, of VIII Josefstädterstrasse 52, Vienna, in the Empire
of Austria, Imperial & Royal Austro-Hungarian Consul, 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 apparatus designed to enable a number of sheets to be
written on at the same places simultaneously and thus to produce in one single
writing operation a number of identical documents. In this apparatus the sheets
which are to be written on by means of a multiple pen or of a multiple lead
pencil, are passed over fixed supporting bars and between pairs of pressure rollers
covered with elastic material and capable of being moved by means of ratchet
mechanism so that the sheets are drawn forward to an extent equal to the distance
between the lines of writing. The writing instrument comprises several pens
or pencils attached to a support which is arranged obliquely to the handle and
which may be attached to the handle either rigidly or pivotally and which is
rendered flexible by means of compression springs or tension springs inserted
between the handle and the support, whereby a uniform bearing of all the pens or
pencils upon the sheets is produced.
An apparatus of this kind for simultaneously writing a number of identical
documents is illustrated in the drawing filed with the Provisional Specification,
wherein Figure 1 is a vertical longitudinal section through the apparatus, shewn
in the position of use. Figure 2 is a side elevation of the apparatus in which some
parts of the same are shewn in the inoperative position. Figure 3 is a plan of the
apparatus. Figure 4, 5, and 6 illustrate three modifications of the multiple pen
(in the present case a triple pen).
As shewn, the box 1 contains transverse bars 2 equal in number to the number
of the identically similar documents that are to be produced. In the side walls

page_text: of the. box 1, or in plates 3 therein, there are mounted three pairs of rollers 4 5,
67, and 8 9, corresponding to the number of cross bars. Of these pairs of rollers
the first two pairs are arranged below the cross bars 2 whilst the third pair of
rollers 89, are arranged behind the last cross bar 2. The rollers of all the pairs
are covered with elastic material, preferably caoutchouc, and they serve to grasp
the sheets to be written on and to draw them forward in a positive manner. The
sheets 10 (indicated by dash-dotted lines in Figure 1) are inserted with their lower
ends loosely into the slot (situated in front of the cross bar as shewn) into the
box. The upper end of the sheet is passed over the corresponding cross bar 2
and is inserted into the slot situated behind the latter in such a manner that the
upper edge of the sheet will be caught by the corresponding pair of rollers. This
is facilitated by the guides 37 which are attached to the lower side of the cross
bars as shewn in Figure 1. The last sheet is inserted directly over the rear
bar 2 between the corresponding pair of rollers 8 9 which are arranged laterally
of the said bar.
.
"
For the purpose of keeping the parts of the sheet that enter the inside of the
box well separated, I provide round bent parallel metal plates 11 which forni
guide slots 12 between them for the sheets that move over the bars. The move-
ment of the pairs of rollers is effected by means of ratchet mechanism which
consists of a ratchet pawl 13 having a handle and ratchet 14 upon the shaft of
which there is mounted a small toothed wheel 15 which is rigidly connected to the
roller 4 and which gears with a toothed wheel 16 of the same size that is
rigidly connected to the second roller 5. The transmission of the motion of the
ratchet mechanism to the other pairs of rollers is effected by means of the toothed
wheel 17 that is mounted on the ratchet wheel shaft, that is to say through the
medium of the intermediate wheels 18, 19, 20, 21. to the pair of rollers 6 and 7,
and from the wheel 19 through the medium of the intermediate wheels 22, 23,
24. and 25 to the last pair of rollers 8 and 9. The transmission is effected, as
will be seen from Figure 2, in such manner that the sheets will be carried along
in the same direction and with the same speed. On the outer end of the ratchet
wheel shaft there is mounted a crank handle 26 by means of which (after the
permanant disengagement of the ratchet pawl from the ratchet wheel) the pairs
of rollers can be rotated at will in either one or the other direction. The stroke of
the ratchet pawl is limited by means of a stop 28 which is movable and is adjust-
able in a slotted arc-shaped piece 27. By shifting this stop the stroke of the
ratchet pawl, and consequently the extent of the forward movement of the sheets,
that is to say the distance apart between the lines, can be varied as desired. For
the purpose of effecting an exact bearing of the sheets upon the surface of the
cross bars there is provided a brake device which consists of a friction roller 29
for each cross bar. The friction rollers are arranged in the slot situated in front
of the corresponding cross bars and are each mounted in a rotary manner in a
common sliding bar 30 at both ends. The rearward extension of the latter
terminates in two pressure knobs 31 that project from the rear wall of the box and
it is subject to the pressure of the flat springs 32 which have a tendency to push
the sliding bars 30 backwards. Below each of the two sliding bars 30 there is a
spring pawl 33 fixed pivotally to the side wall of the box. This pawl is caused
by the forward movement of the sliding bar 30 produced by pressing the knob 31,
to engage over a conical lug 34 on the bar of 30 and to keep the latter in its
position. A pin or knob 35 fixed on the side of the pawl 33. extends through a
slot 36 in the side wall of the box and it can be pressed down by hand in
opposition to the action of the spring so as to disengage the sliding bar 30 which
is pressed forward by the action of the spring 32. When both sliding bars have
been disengaged in this manner, all the friction rollers 29 bear against the front
surfaces of the corresponding cross bars with the result that the sheets of paper
which are situated between the cross bars and the friction rollers, are gripped
with a moderate pressure. By means of the friction thus produced the sheets
are maintained in tension so that they will lie flat upon the cross bars.

page_text: The pens or pencils used for writing comprise as many pens or pencils 38 as
there are cross bars 2. In the present case there are three of such pens 38 which
are fixed to a holder 40 that is arranged at a suitable angle to the handle 39. In
the arrangement shewn in Figure 4 the holder 40 is rigidly connected to the
handle. In the multiple pen shewn in Figure 5 the holder 40 is pivotally con-
nected at its middle to an extension 41 of the handle 39 substantially parallel
to the part 40, compression springs 43 being inserted at both ends between the
parts 40 and 41. In the arrangement shewn in Figure 6 two arms 42 that form
a fork are fixed to the handle 39 and the holder is pivotally mounted in the ends
of said arms, a spiral spring 43 being inserted between the handle 39 and the
holder 40.
In writing, the pen is placed upon those parts of the sheets of paper (that are
clamped in the manner described) which pass over the cross bars. To write with
the rigid pen, Figure 4, requires a greater skill than to write with the two
other pens, the latter being more easily manipulated because owing to the yielding
connection of the holder 40 with the handle of the pen a constantly uniform
bearing or pressure of all the pens upon the sheets is ensured. In all cases the
hand must however be well supported during writing and for this purpose there
is provided at the front of the box a sloping plate 44 which consists preferably of
a number of parts hinged together and which is supported by means of side
pins 45 in vertically slotted guides 46 projecting in front of, and attached to, the
side walls of the box. In position of use, as shewn in Figure 1, the front edge
of the plate 44 rests on the table and the pins 45 are supported by the lower
ends of the guides 46. When the apparatus is out of use the plate 44 can be
folded together as shewn in Figure 2 and over the whole apparatus as a cover.
To the rear edge of the box there is hinged an apparatus designed for blotting off
the freshly written matter. This apparatus consists of a hinged plate 47 which
is raised by spring pressure and upon which blotting paper 49 is stretched over
an elastic underlay 48. This blotting paper is fixed at one end in a slot in the
plate and at its other end is wound on a rotary clip 50 of any known kind. The
plate 47 is connected by a link 51 and lever 52 with a slotted lever 53 by
depressing which the plate is brought down so that the blotting paper can blot
off the freshly written matter on the sheets.
Having now particularly described and ascertained the nature of the said
invention and in what manner the same is to be performed I declare that what
I claim is:-
1. Apparatus to enable a number of sheets to be written on simultaneously so
as to produce a number of identical documents, comprising supporting bars for
the sheets and a number of pairs of rollers 4 5, 67, 89, (corresponding to the
