COMPLETE SPECIFICATION.
Improvements in or relating to Platen Printing Presses.
I, JOHANN BERNHARD GROSSE, Proprietor of a Printing Office, of 20, Erdmann
Strasse, Leipzig, Lindenau, Saxony, in the Empire of Germany, do hereby
leclare the nature of this invention and in what manner the same is to be per-
formed, to be particularly described and ascertained in and by the following
statement:
-
The present invention relates to platen presses and consists of a device by
means of which the paper or other material to be printed may be simultaneously
ruled.
In order to render the present specification more easily intelligible reference is
had to the accompanying drawing in which similar letters of reference denote
similar parts throughout the several views:-
Figure 1 is a side elevation of a platen press with the ruling device about to
operate,
Figure 2 is a similar elevation showing the press with the platen pressed
against the type,
Figure 3 is a front elevation of the press.
Figure 4 is a detail cross section and longitudinal section of the combined ink
roller and reservoir.
To the platen a are attached rails bb on which the carriage with the ruling
device runs.
At the upper ends of the said rails are guide rolls f f for chains
or cords having one end attached to the ruling device and the other to a
stationary bar g of the press frame, so that when the platen is turned on its hinge
to bring the paper on to the type box the carriage with the ruling device will be
drawn upwardly and will cause the line producing discs to pass over the paper
before the latter comes into contact with the type. The carriage consists of the
end plates kk which are guided advantageously on the rails bb by means of
three rolls l, m, n and connected together by means of a cross bar d. Between
these plates and mounted to rotate in the same is the shaft h having the ruling
discs and an inking roll i, shown in detail in Figure 4.
This roll serves simultaneously as ink holder or reservoir being hollow and
perforated and provided with suitable coverings of cloth or any suitable material
capable of absorbing the colour or ink. This roll supplies the colour or ink
to the discs of the shaft h. The bar o which connects the end plates kk is
advantageously provided with a strip of felt or similar material arranged to brush
the ruling discs and also to brush the ink roller i and take any superfluous ink
Instead of felt brushes may be attached along the said
or colour off the same.
bar.
The operation of the device will be clear from the foregoing specification.
When the platen is thrown back the ruling carriage is at the bottom of the same
as shown in Figure 1 and as the platen is moved towards the type the carriage k k
is drawn upwardly over the paper on the platen ruling the same and finally
arriving at the top of the rails out of the way of the type when the platen is
pressed on to the latter.

page_text: Having now particularly described and ascertained the nature of my said
invention and in what manner the same is to be performed I declare that what
I claim is:
1. In a platen press the combination of a shaft having ruling discs thereon,
means for inking the discs and means for moving the said shaft across the
paper when the platen is turned to print the type substantially as described.
2. In a platen press the combination of a ruling device and means for passing
the same over the paper or other material being printed, whilst the platen is
being passed from its initial position to the type substantially as described.
3. In a platen press the combination of rails at either side of the platen, a
carriage to run on same and having a ruling shaft with discs and means for
inking the same and means for passing said carriage from the bottom to the top
of the platen whilst the latter is being moved towards the type substantially as
described.
4. In a platen press the combination of rails at either side of the platen, a
carriage to run on said rails said carriage having a shaft with ruling discs
mounted thercon and an inking roller with ink reservoir, guide rolls at the
top of the rails and cords or chains attached at one end of the carriage and at the
other to a stationary part of the press in the manner and for the purpose
substantially as described.
5. In a platen press the combination of a carriage having a ruling device as
specified and means for passing the same over the platen whilst the latter is
being moved and an inking roll to said ruling device consisting of a perforated
cylinder having stuff covering in the manner and for the purpose substantially
as described.
6. In a platen press the combination of a carriage having a ruling device.
thereon and means for operating the same as specified, a cross bar to said carriage
having a brush to brush both the inking roll and the ruling discs substantially
as described.
ated this 20th day of May 1899.
