PAPER PRINTING."
Sealed the 19th December 1876, and dated the 23rd June 1876.
PROVISIONAL SPECIFICATION left by the said Ferdinand Tilgmann at the
Office of the Commissioners of Patents on the 23rd June 1876.
FERDINAND TILGMANN, Lithographer, in Helsingfors, Finland. "AN IMPROVED
PRESS FOR BOOK AND WALL PAPER PRINTING."
This Invention has for its object on the one hand to render the fly press more
efficient than those in use heretofore by employing on it endless paper, and avoiding
thereby the laying of every sheet of paper separately; on the other hand the said
Invention has for its object to obtain a better printing by using the ordinary print
form. Moreover, this Invention affords the means for adapting this printing to
the manufacture of hangings for the decoration of rooms.
The machine employed for carrying this Invention into practice raises and lowers
a press table with the print form on it, and presses thereby against the under side
of the paper above the table; the paper is sustained by another table. The printing
being done the press table descends, and by a feed roller new paper of the required
dimensions is drawn forward; then the print form remains immovable till a series
of inking rollers have supplied the print form on the press table with fresh ink.
Figure 1 in the accompanying Drawing represents a side view of the said machine;
Figure 2, a plan; and Figure 3, a vertical section through the centre of the press
table.
Similar letters indicate the same parts throughout the Drawing.
In a bed plate a of cast iron are fixed mountings b, which are united by the counter-
pressure table c.
The press table d, with the print form on it, moves against guides
fixed on the lateral faces exactly in a vertical direction up and down. This up-
and-down movement is obtained by two excentrics f, g, turning on bolts h, i, the
bolt h being inserted in the press table d, the other i in the bearings k of the bed
plate a.
To prevent the sliding of the faces of the excentrics on each other when
turning on their bolts the excentrics receive a circular motion by means of a frame 1,
between the parallel faces of which slide two bearings m containing the pins n, n,
[Price fd1

page_text: on the two excentric pieces. The frame has a horizontal motion, and at right
angles with the line passing through the centres of the bolts, to which end the
guiding piece o is screwed on the front mounting b. The driving shaft p being
turned by means of a pulley or a fly wheel the crank q will by the connecting rod r
give a to-and-fro motion to the frame 1, and thereby the excentrics ƒ and g are
actuated according to the form of the excentrics the distance between the two
bolts h and i will increase or diminish, and the press table d will be raised or
lowered.
The form of the excentrics is such that during the first half of the course no
vertical motion takes place. The excentrics are pressed against each other by coiled
springs 8, which act on the levers x, the tension of which is transmitted to the press
table by means of the rods u and the bolts v¹. The tension of the two springs is
maintained uniformly by junction of their lower extremities to the ends of a two-
armed lever w. The apparatus for obtaining a good print is inserted in a frame
below the press table c. This frame rests with its lateral faces on guide bars con-
nected to the rods t and the connecting piece F, and can be raised or lowered by
means of the screw G. The print form is fixed on the table d, which at its upper
face contains an arrangement for taking the form easily away.
The feeding of the paper is effected by a roller, on which are mounted two
movable wheels. The paper to be printed lies on a roller A, Figure 1, whose axle
is provided with a movable weight b¹ to avoid any vibration. It passes between
the guiding rollers D, E, below the counter pressure table, and further between the
feeding roller B and the wheel C, which is pivoted in excentric bearings pressed
against the feeding roller by means of a lever.
The motion necessary for the feeding of the paper is communicated to the feeding
roller B by a pinion mounted loosely on its axle, and gearing with a toothed bar b
the end of which is connected by the rod u to the press table d. The pinion is
loose on the axle of the feeding roller B, so that by raising the toothed bar b² the
feeding roller remains immovable. If the press table d is lowered, and thereby the
connecting rod u acts downward, the turning of the pinion is prevented by means
of a coiled spring and by the gearing of the pinion on the axle of the feeding roller
with the toothed bar 62 the feeding roller will be turned, thereby causing the fresh
paper to be drawn below the counter pressure table, and the finished printing
removed.
By disconnecting the wheels C paper of different widths can be raised at the sides
and fed to the machine.
The inking apparatus above the driving shaft consists of a roller Q, receiving by
a pulley and a toothed wheel a slow rotary motion, and thereby spreading the ink
from the reservoir R on its surface. The rollers v, V, v, receive their ink from the
roller Q. On two guide bars fixed at the two sides inside of the mountings b, b, a
series of rollers slide in bearings. To these bearings and rollers a sliding motion
along the guides is communicated from the bolt i fixed on the eccentric g by means
of levers.
During the time the front rollers ?, ?, are passing above the form and inking it
the other rollers v, V, v, turn on an inking table; the roller V in the middle moves
against the roller Q of the inking apparatus, obtains the ink therefrom, and by
this and the other rollers v, v, turning in opposite directions the ink is spread over
the table.
The arrangement of the apparatus is such that while the excentric keeps the press
table d in its lowest position the rollers 7, 7, slide over the form, and the rollers
v, V, v, pass over the table and return. The inking rollers v, V, v, having passed
the form crises, and the printing takes place. Meantime, the rollers pass and
return over the inking table, the press table is lowered, and at the same time by
means of the connecting rod u connected with the toothed bar 62 fresh paper is fed
by the feeding roller below the press table c.

PRESS FOR BOOK AND WALL PAPER PRINTING."
"AN IMPROVED
This Invention has for its object on the one hand to render the fly press more
efficient than those in use heretofore by employing on it endless paper, and avoiding
thereby the laying of every sheet of paper separately; on the other hand the said
Invention has for its object to obtain a better printing by using the ordinary print
form. Moreover, this Invention affords the means for adapting this printing to the
manufacture of hangings for the decoration of rooms.
The machine employed for carrying this Invention into practise raises and lowers
a press table with the print form on it, and presses thereby against the under side
of the paper above the table; the paper is sustained by another table. The printing
being done the press table descends, and by a feed roller now paper of the required
dimensions is drawn forward; then the print form remains immovable till a series
of inking rollers have supplied the print form on the press table with fresh ink.
In the accompanying Drawing Figure 1 is an elevation of the said machine;
Figure 2 is a plan of the same; Figure 3 is a vertical transverse section through the
centre of the press table.
Similar letters indicate the same parts throughout the Drawing.
On a bed plate a of cast iron are fixed mountings b, which are united by the
counter pressure table c. The press table d, with the print form on it, moves
against guides fixed on the lateral faces exactly in a vertical direction up and down.
This up-and-down movement is obtained by two excentrics f, g, turning on bolts h, i,
the bolt being inserted in the press table d, and the other i in the bearings k of
the bed plate a. To prevent the sliding of the faces of the excentrics on each other
when turning on their bolts the excentrics receive a circular motion by means of a
frame 1, between the parallel faces of which slide two bearings m containing the
pins n, n, on the two excentric pieces. The frame has a horizontal motion at right
angles with the line passing through the centres of the bolts, to which end the
guiding piece o is screwed on the front mounting b. The driving shaft p being turned
by means of a pulley or a fly wheel the crank q will by the connecting rod * give
a to-and-fro motion to the frame I, and thereby the excentrics ƒ and g are actuated;
according to the form of the excentrics the distance between the two bolts h and i
will increase or diminish, and the press table d will be raised or lowered.
The form of the excentrics is such that during the first half of the course no
vertical motion takes place; the excentrics are pressed against each other by coiled
springs 8, which act on the levers x, the tension of which is transmitted to the press
table d by means of the rods u and the bolts v¹. The tension of the two springs is
maintained uniformly by junction of their lower extremities to the ends of a two-
armed lever w. The apparatus for obtaining a good print is inserted in a frame
below the press table c. This frame rests with its lateral faces on guide bars
connected to the rods t and the connecting piece F, and can be raised or lowered by
means of the screw G. The print form is fixed on the table d, which at its upper
face contains an arrangement for taking the form easily away.
The feeding of the paper is effected by a roller, on which are mounted two
movable wheels. The paper to be printed lies on a roller A, Figure 1, whose axle
is provided with a movable weight b' to avoid any vibration; it passes between
the guiding rollers D, E, below the counter pressure table, and further between the
feeding roller B and the wheel C, which is pivoted in excentric bearings pressed
against the feeding roller by means of a lever.
The motion necessary for the feeding of the paper is communicated to the feeding
roller B by a pinion mounted loosely on its axle, and gearing with the toothed bar b
the end of which is connected by the rod u to the press table d. The pinion is

page_text: loose on the axle of the feeding roller B, so that by raising the toothed bar 63 tho
feeding roller remains immoveable. If the press table d is lowered, and thereby the
connecting rod u acts downward, the turning of the pinion is prevented by means
of a coiled spring and by the gearing of the pinion on the axle of the feeding roller
with the toothed bar 62, the feeding roller will be turned thereby, causing the fresh
paper to be drawn below the counter pressure table, and the finished printing
removed.
By disconnecting the wheels C¹ paper of different widths can be raised at the
sides, and fed to the machine.
The inking apparatus above the driving shaft consists of a roller Q receiving by
a pulley and a toothed wheel a slow rotary motion, and thereby spreading the ink
from the reservoir R on its surface. The rollers v, V, v, receive their ink from the
roller Q. On two guide bars fixed at the two sides inside of the mountings b, b, a
series of rollers slide in bearings. To these bearings and rollers a sliding motion
along the guides is communicated from the bolt i fixed on the excentric g by means
of levers.
During the time the front rollers ?, ?, are passing above the form, and inking it,
the other rollers v, V, v, turn on an inking table; the roller V in the middle moves
against the roller Q of the inking apparatus, obtains the ink therefrom, and by this
and the other rollers v, v, turning in opposite directions the ink is spread over the
table.
The arrangement of the apparatus is such that while the excentric keeps the
press table & in its lowest position the rollers r, r, slide over the form, and the
rollers v, V, v, pass over the table and return. The inking rollers v, V, v, having
passed the form u rises, and the printing takes place. Meantime, the rollers pass
and return over the inking table, the press table is lowered, and at the same time
by means of the connecting rod u connected with the toothed bar 62 fresh paper is
fed by the feeding roller below the press table e.
Having thus fully described my said Invention, and the manner of performing
the same, I wish it understood that I claim, the improved press, in the construction
and use of which the following novel features are composed, namely:-
First. The raising of the form and printing of the paper, sustained on its upper
face at the lower face of the same, as above set forth.
Second. The use of endless paper for the ordinary print form, as above set
forth.
Third. The mechanism for raising the press table, especially the arrangement for
ensuring the equal motion of the two excentrics, as above set forth.
Fourth. The feeding apparatus for the paper so arranged that by the moveable
wheels paper of different widths will be seized at the sides remaining unprinted, and
thereby fed, as above set forth.
In witness whercof, I, the said Ferdinand Tilgmann, have hereunto set my
hand and seal, this Seventeenth day of December, in the year of our Lord
One thousand eight hundred and seventy-six.
