I, JACOB HEINRICH MISSONG, of Höchst / Main, Prussia, in the Empire of
Germany, Engineer of the Colourworks, formerly Master, of Messrs. Lucius & Brüning,
do hereby declare the nature of this invention to be as follows:-
This invention has for its objects, firstly, a reliable carrying of the sheets to be
printed, through the printing machine without grippers and tapes, applicable to
any kind of cylinder printing machine.
Secondly, in machines for printing on two sides, preventing the setting off or soiling
of the pressing cylinder and the sheets, by the employment of rigidly mounted
cylinders.
Thirdly, a reliable action of the clutch box couplings.
In this invention the driving mechanism employed is the so-called carriage motion,
with crank driving or circular driving,
When the carriage is moved forwards, i.e. from the left to the right a set of racks
connected therewith come into gear with spur wheels fixed on the shaft of the first
pressure cylinder, (cylinder engaged when printing the first side), and rotate the
same from the right to the left.
If the carriage is running backwards, the first pressure roller is caused to stop by
means of an eccentric and forked lever.
On each end of the shaft of the second pressure cylinder (cylinder engaged when
printing the second side) are mounted loosely two spur wheels which by means of a
clutch box coupling, can be coupled to and uncoupled from the said shaft, self-
actingly.
The outer of these spur wheels remains always in gear with the spur wheels, fixed
on the first pressure cylinder which are of such a width as to gear with the said set
of racks.
When the carriage in moving forwards, the outer spur wheels & shaft of the second
pressure cylinder are coupled & give the respective cylinder a turn to the right.
During this rotation the inner of the second pressure cylinder spur-wheels are in
gear with another set of racks, placed on the side of the first named set and uncoupled
from their shaft and permitted to make a turn to the left, viz., in a reversed direction

page_text: to the rotation of the second pressure cylinder. When the carriage is moving
backwards, the outer of the second pressure cylinder spur wheels, are uncoupled from
their shaft & stopped by means of the spur wheels on the first pressure cylinder shaft
which are then at rest being out of gear with the respective set of racks. During this
period the inner spur wheels & the shaft of the second impression cylinder are coupled
with their shaft and make a turn to the right.
The second pressure cylinder therefore rotates during the to & fro motion of the
carriage always in one direction i.c. to the right.
The inner spur wheels on the second pressure cylinder shaft being in gear with the
respective racks, cause a reversed rotation of the same alternately, on account of the
to and fro motion of the carriage.
As already mentioned the second pressure cylinder is required to rotato always in
the same direction, which can only be attained by an absolute certain action of the
clutch box coupling.
In order to obtain the time necessary for moving the clutch into gear, the travel of
the carriage or racks is made larger than the circumference of the pitch line of the
pressure cylinder wheels.
To obtain an equal circumferential speed of the pressure cylinders, the same are
made of equal diameters and the respective spur wheels of equal pitch line diameter.
The pressure cylinder & carrier roller are provided with axial and radial holes which end
in a pipe situated on the circumference which possesses small holes leading to the exterior.
The pipe conduits are alternately brought into connection with a space containing
diluted or compressed air, or the atmosphere.
The regulation of the entering and issuing air may be caused by valves etc.
The laying on of the sheet on the first pressure cylinder takes place when the same
is at rest.
After the sheet has been laid on, the air pipe of the first pressure cylinder is brought
in communication with the space containing diluted air by means of the said valve, etc,
and thereby the sheet sucked against the first pressure cylinder. The latter latter
cylinder revolves afterwards and carries the sheet over the type form, whereby the
same receives the impression on the first side.
Shortly before the pressure cylinders get into opposite position, the air pipe of the
former is brought self-actingly in communication with the atmosphere, or a room
containing compressed air, while at the same time the air pipe of the latter is brought
into communication with the space containing diluted air, the first pressure cylinder
releasing the sheet of paper and the second pressure cylinder sucking it on again.
After the first pressure cylinder has delivered the sheet to the second pressure
cylinder the same revolves further into its original position where it remains standing,
as the teeth of the respective spur wheel, which at that time come into gear, are cut out,
and the same is then arrested by means of a stopping motion.
During the stopping of the first pressure cylinder the second pressure cylinder makes
a revolution with its sheet during which an impression on the second side of the sheet
takes place.
If the second pressure cylinder has again arrived in its original position the first
pressure cylinder with its sheet commences its next revolution by bringing the
respective wheel, by means of the forked lover, into gear, during which moment the
next sheet is brought into the machine.
The sheet fed in first rotates with the second impression cylinder until it has reached
a certain position.
The transmition of the sheet from the second impression cylinder to the delivery or
carrier cylinder, takes place in the same manner as from the first pressure to the
second pressure, rollers.
The delivery or carrier roller is rotated by means of a spur wheel, which gears into
another spur-wheel, fixed on the second pressure cylinder shaft.
The delivery or carrier roller carries the sheet to the tape roller and delivers it to
an endless band which carries the sheet to the delivery table in the same manner as is
the case in a single cylinder machine.

page_text: To prevent the setting off of the colours of the first pressure cylinder, on the
covering of the second pressure cylinder, and the ultimate soiling when printing on
the second side, compressed and dried air enters through the pipes which on their
entire length are provided with holes, which absorb the dampness of the printing
colours.
--
The soiling of the first impression cylinder in machines printing on both sides, by
the type forms, is not prevented in the manner known heretofore, but as follows :-
The pressure cylinders are arranged to rotate in stationary bearings, the second
pressure cylinder laying against and being situated a little higher than the first
pressure cylinder in order that the type form for the first impression can pass freely.
During the travel of the carriage from the right to the left (period of the second
impression) the first pressure cylinder remains still & permits the type forms to pass
freely, as on its lower part a portion of the circumference is cut out.
A soiling of the second impression cylinder can only be prevented when not lifting
the same and by laying the left end of the type form in such a manner, as to pass the
vertical line through the centre of the second impression cylinder on the to and fro
notion of the carriage at half of its travel.
As the second impression is caused during the two motions of the carriage, the
second pressure cylinder makes by each to and fro motion of the carriage, one
revolution, the left side of the same only can be used as pressure surface. The second
pressure cylinder therefore presses exclusively only on one side, the other side being
made smaller correspondingly, preventing the contact with the type forms which is
partly attained by covering the cylinder only at the pressure surface. The first
pressure cylinder, which on the carriage moving forwards, presses onto the type forms,
is on the other side, viz., the side that does not press, formed smaller, so as to permit
the type forms to pass freely.
The size of the sheet to be printed has to be equal or smaller than half of the
circumference of the pressure rollers.

Improvements in Printing Machines.
I, JACOB HEINRICH MISSONG of Hochst-am-Main, Prussia, in the Empire of Germany,
Engineer, of the Colourworks, formerly Master, of Messrs. Lucius & Brüning, 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:
The principal object of this invention a reliable carrying of the sheet to be printed,
through the printing machine without grippers and tapes.
The drawings annexed show the improvements applied to a machine printing on
two sides with type bed moving to and fro, and by which the sheet is fed onto the first
pressure cylinder by hand or self-actingly and also to a rotary printing machine.
And in order that my invention may be better understood I have cause to be
appended hereunto three sheets of drawings marked with letters of reference indicating
like parts in the various figures.
Fig. 1 Sheet I is a side view of a machine printing on two sides, in which the paper
is fed by hand.
Fig. 2. Sheet II a plan of the first pressure cylinder A, second pressure cylinder B,
carrier roller 1, the foundation or carriage F, with the two type formes &, the
fly wheel shaft w', with its fly-wheel R, the spur wheel r, the crank shaft w², with the
spur wheel, and the crank K.
Fig. 3. Sheet, is a longitudinal section of the cylinders A & B, which are alike.
Figs. 4. 5. & 6 Sheet II show the characteristic positions of the different cylinders
to each other, owing to the manner of action of the machine.
The driving mechanism employed is the so-called carriage motion with crank or
circular driving.
When the carriage is moved forwards., i.e. from the left to the right, a set of racks s
connected therewith come into gear with spur wheels a fixed on the shaft of the first
pressure cylinder A (cylinder engaged when printing the first side), and rotate the
same from the right to the left.
If the carriage is running backwards, the first pressure roller A is caused to stop
by means of an eccentric and forked lever.
On each side of the shaft of the second pressure cylinder B (cylinder engaged
when printing the second side) are mounted loosely two spur wheels 1 & 2 which by
means of a clutch box coupling, can be coupled to and uncoupled from the said shaft,
self-actingly.
gear
with the spur wheels a which latter are of
The spur wheel & remains always in
such a width us to gear with the racks Fig. 2.
When the carriage is moving forwards, the wheels are coupled with the shaft d²,
and rotate the respective cylinder B from the right to the left.
During this rotation the spur wheels 2 which are in gear with the respective carriage
racks s², are uncoupled on their shaft, and are permitted to rotate loosely on the same

page_text: from the right to the left, namely, in a reverse direction to the rotation of the second
pressure cylinder B. When the carriage is moving backwards the spur wheels b' are
uncoupled from their shaft and are kept fast by means of the spur-wheels a which are
then at rest.
During this action the spur wheels are coupled with the shaft d², and the second
pressure cylinder rotates from the right to the left, and is therefore rotated on the
carriage running forwards or backwards in the same direction, that is to say from the
left to the right.
The spur wheels 2 being in gear with the respective racks will be caused to rotate
alternately on account of the to and fro motion of the carriage in a reverse direction.
As already mentioned the second pressure cylinder B is required to rotate always in
the same direction, which can only be attained by an absolutely certain action of the
clutch box couplings.
In order to obtain the time necessary for moving these clutches into gear, the travel
of the carriage or racks is made larger than the circumference of the pitch line of the
pressure cylinder wheels.
To obtain an equal circumferential speed of the pressure cylinders, the same are
made of equal diameters, and the respective spur-wheels a, b, & b², of equal pitch-
line diameter.
The pressure cylinders A & B and carrier roller D are provided with axial and
radial holes which end in a pipe situated on the circumference, which possesses small
holes leading to the exterior, see Fig. 3.
These pipe conduits are alternately brought into connection with a space containing
rarified, or compressed air, or with the atmosphere.
The regulation of the entering and issuing air may be caused by valves, etc.
The laying on of the sheet on the first pressure cylinder A takes place when the
same is at rest, see Fig. 1.
After the sheet has been laid on, the air pipe of the first pressure cylinder A is
brought in communication with the space containing rarified air by means of the said
valve, etc, and thereby the sheet sucked against the first pressure cylinder A.
The latter cylinder revolves afterwards and carries the sheet over the type form f¹,
whereby the same receives the impression on the first side.
Shortly before the pressure cylinders get into the position shown in Fig. 4. the air-
pipe of the former is brought self-actingly in communication with the atmosphere, or
a room containing compressed air, while at the same time the air pipe of the latter is
brought into communication with the space containing rarified air, the first pressure
cylinder A releasing the sheet of paper and the second pressure cylinder B sucking it
on again.
After the first pressure cylinder A has delivered the sheet to the second pressure
cylinder B, the same revolves further into its original position, where it remains
standing, as the teeth of the respective spur wheel a which at that time would come
into gear, are cut out, and the same is then arrested by means of a stopping motion.
During the stopping of the first pressure cylinder A the second pressure cylinder B
makes a revolution with its sheet, during which, an impression on the second side of
the sheet takes place.
If the second pressure cylinder B has again arrived in the position shown in Fig. 1,
the first pressure cylinder A with its sheet, commences its next revolution by bringing
the respective wheel a, by means of the forked lever G into gear, during which
moment the next sheet is brought into the machine.
The sheet fed in first rotates with the second impression cylinder B, until it has
reached the position indicated in Fig. 5.
The transmission of the sheet from the second impression cylinder B to the delivery
or carrier cylinder C, takes place in the same manner as from the first to the second
pressure cylinders.
The delivery or carrier roller C is rotated by means of a spur wheel
into another spur wheel c fixed on the second pressure cylinder shaft d².
which gears
The delivery or carrier roller C carries the sheet to the tape roller D where it lets it

page_text: go (see position indicated in Fig. 6) and delivers it to an endless band & see Fig. 1,
which carries the sheet to the delivery table in the same manner as is the case in a
single cylinder machine.
To prevent the setting off of the colours of the first pressure cylinder A, on the
covering of the second pressure cylinder B, and the ultimate soiling when printing
on the second side, compressed and dried air enters through the pipes y, see Fig. 1,
which on their entire length are provided with holes, which absorb the dampness of
the printing colours.
The soiling of the first pressure cylinder A by the type forms, in machines printing
on both sides, is not prevented in the same manner as heretofore, but as follows:-
The pressure cylinders A & B are arranged to rotate in stationary bearings, the
second pressure cylinder B laying against and being situated a litle higher than the
first pressure cylinder A, in order that the type form f" for the first impression can
pass freely.
During the travel of the carriage from the right to the left (period of the second
impression) the first pressure cylinder A remains still and permits the type forms f"
& to pass freely, as on its lower part a portion of the circumference is cut out.
A soiling of the second impression cylinder B can only be prevented without lifting
the same, by laying the left end of the type form 2 in such a manner as to pass the
vertical line through the centre of the second impression cylinder B on the to and
fro motion of the carriage after half of its travel.
As the second impression is caused during the fro motion of the carriage, the second
pressure cylinder B makes on each to and fro motion of the carriage, one revolution,
the left side, n, r, q, see Fig. 1, of the same, only can be used as pressure surface.
The second pressure cylinder B therefore passes exclusively only on one side n, r,
9, the other side n, o, p being made smaller correspondingly, preventing the contact
with the type forms, which is partly attained by covering the cylinder only at the
pressure surface n, r, q. The first pressure cylinder A which on the carriage moving
forwards, presses on to the type forms f", is on the other side t, viz., the side that
does not press, formed smaller so as to permit the type forms f² to pass freely.
The size of the sheet to be printed has to be equal or smaller than half of the
circumference of the pressure cylinders.
Fig. 7. Sheet III, show the application of the means for carrying the paper to a
rotary printing machine, and Fig. S to a machine printing on both sides, and to and
fro moving type bed, and automatic feed of the sheets.
The paper to be printed is drawn in the well known manner from an endless paper
roll, by means of the guide rollers 1, 1, to the feed rollers L, L¹, see Figs. 7, & 8.
The feed rollers push the paper between the cutting cylinders c¹ c², as well as the
cutting cylinder c¹ and pressure cylinder S¹ or carrier cylinder F¹ into the indicated
vertical position.
The cutting cylinders only come in contact with each other at the moment the cut is
made and the lower cutting cylinder leaves a free space of a few sixteenths of an
inch between the pressure cylinder S¹ or carrier cylinder, to permit the paper to pass.
After the feed rollers have pushed through between the cutting cylinders and the
lower cutting cylinder, and the first pressure roller S², or carrier cylinder, a certain
size of paper, the cutting off of the same takes place, and at the moment of cutting,
the sheet is sucked on the back edge, by means of the suction arrangement and
on to the lower cutting cylinder & held there until the same is delivered to the first
pressure or carrier cylinder F rotating in the same manner, which brings it to the
first pressure cylinder.
The diameter and speed of the upper cutting cylinder, which is provided with the
knife is so arranged, that the same in rotary printing machines, on one revolution of
the pressure cylinders, and by machines with to and fro moving type bed, during the
to and fro motion of the type bed will make one revolution and respectively cut off a
sheet of paper.
Fig. 7 Sheet III. indicates the position of the machine at the moment when the
sheet is cut off and sucked on the back edge on to the lower cutting cylinder.

page_text: Fig. S shows a position, in which the sheet is delivered from the lower cutting
cylinder to the carrier cylinder F¹.
By the application of the feed rollers, see Fig. 8, the paper is fed by being pushed
intermittently at the speed of the cutting cylinder, whereby the sheet at the moment
of cutting, on the back edge of the cut and the front edge of the following sheet, is
sucked on simultaneously.
The feed rollers, see Fig. 7, may be substituted by the feed rollers shown in Fig. 8.
The carrying of the paper over the pressure cylinders S1, S2, and from the latter to
the delivery apparatus, takes place in the manner already described.
Having now particularly described and ascertained the nature of this invention and
in what manner the same is to be performed I declare that what I claim is :-
1st. The employment of rarified air for sucking the sheet to be printed on to the
cylinders of printing machines of any kind, for the purpose of holding and carrying
the sheet, as well as the reliable transmitting of the same from one cylinder to the
other, whereby air of atmospheric and higher pressure is used for removing the sheet,
as set forth.
2nd. A suction device arrangement on the lower part of the cutting cylinder C₁
in such a manner that the back edge of the sheet of paper carried through is sucked
on shortly before the moment of cutting, for the purpose of obviating the adjust-
ment of the cutting cylinder when altering the size of the paper and to ensure an
exact and positive carrying of the paper to the pressure cylinder as set forth.
4th. Preventing the soiling of the cylinder and sheet, in particular by machines
printing on two sides, which is obtained by
a) mounting the second pressure cylinder against and higher than the first
pressure cylinder,
b) by stopping the first pressure cylinder during the time when the printing of
the second side takes place,
c) and by arranging the dimensions of the pressure cylinder in such a manner,
that half of their upper cylinder surface is not smaller but equal or larger
than the size of the sheet to be printed, and the radius of the cylinder halves
presented at the end of the travel of the carriage will be larger than the cylinder
halves pointing outwards, as set forth.
