Method of and Apparatus for Producing Simultaneously Polychrome
Printing upon Rotary Presses.
We, MARTIN ALEXANDER WALDECK of 125 Potsdamerstrasse Berlin, W., in the
Empire of Germany, Doctor of Philosophy and EDOUARD CARL DE HAKEN of
70 Schluterstrasse, Charlottenburg in the Empire of Germany, Honorary Russian
Counsellor, 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 by means of which smaller or larger portions
of the paper roll can be printed in several colours upon any rotary printing press
without great cost and without loss of time. In order to effect this object, it
would be sufficient to arrange in front of the printing cylinder a small roller with
colouring or inking device for printing a line, a name, or any other striking mark
automatically in colour upon a certain part of the paper web which remains free
between the printing cylinder and the type cylinders in producing ordinary black
printing. This small roller may be of any suitable construction and be operated
in any suitable manner. The said roller can therefore he arranged at any suitable
part of the rotary press so that the type cylinders are always compelled to leave the
same places free for colour printing; It can either be combined with a suitable
separate rinting roller or it can be connected to one of the existing large printing
rollers. In both cases it can be rotated from any suitable parts of the gearing of
the rotary press. Also the mode of mounting the same, as also its special con-
struction, may be selected according to the circumstances of each case. The
colour printing roller may be provided with colour in any desired manner which
will also depend on the general arrangement of the apparatus. Since the shape
of this roller is also quite optional, entirely different forms of construction may
be employed for different purposes. For simple lines and short advertisements it
is sufficient as above stated to use a small roller. But where larger surfaces or
areas have to be printed in colour, the said small roller becomes a regular type
cylinder. In the accompanying drawings, Figures 1 and 2, show a form of con-
struction of the first kind; Figure 3 shows a construction of the second kind.
From the roller C (Fig. 2) the paper to be printed upon passes over the guide
spindles D, D1, D2, to the pair of type cylinders and printing cylinders for per-
fecting A, A, and B, B₁ (Fig. 1) and thence to the pressure or printing
cylinders A2, A3, and B2, B3 Before the web passes to the printing cylinders it
is led over the roller E which produces the colour printing. The roller E is
mounted in the double armed lever M, the other end of which is drawn down by a
spring L in such a manner that the double lever which is pivotted on the bolt I
swivels outwardly with its end that carries the roller E. On the outside of the
printing cylinder B or of the toothed wheel actuating said cylinder, there is
arranged a dog or carrier H which engages the suitably bent end k of the double
lever M on the rotation of the printing cylinder in such a manner that the other
end of the double lever is moved with the roller E against the printing cylinder.
If the rotary press be set in motion, the paper band passes over the guide spindle D

page_text: through the steam chest, over the guide spindles D', D2 to the cylinder B, whence
it follows the path indicated by arrows. On the rotation of the cylinder B the
carrier H lifts the end k of the lever M in opposition to the pull of the spring L,
so that the roller E, whilst rubbing upon its inking device, bears firmly against the
paper ban which is moving forward on the printing cylinder B. In this connection
the roller E rotates together with the cylinders. The length of the carrier H is such
that the roller E makes exactly one revolution. On the expiration of this revolu-
tion, the end of the lever M is released by the carrier H and is drawn by the
spring L back into its initial position, so that the roller E rubs again against its
inking device F, g and thus always prints again anew. Thus at every revolution
of the printing cylinder B a definite coloured impression is produced on the paper
band. On the forme-cylinder A are arranged the types for the place of impression
to be marked in colour in such a manner that these places appear in two colours (in
black and in another colour). Also the types may be omitted altogether on the
forme-cylinder for this place which has the effect of causing the place to be of one
colour only, but in a colour other than the other parts of the paper band. By
means of the apparatus just described only a small number of horizontally arranged
lines can be printed in a column or across the whole band of paper. When this
annaratus is not sufficient, a large roller must be employed formed as a type
cylinder. The apparatus can be readily applied in this form also to rotary
presses. A combination of this kind is shown in Figure 3. The colour printing
cylinder E inserted in this case has the same length; and, if the blocks to be
arranged thereon are also reckoned, it has also the same diameter as the type
cylinders A, A' and is similarly rotated by means of a toothed wheel connected
to the gearing of the rotary press. The cylinder E consists preferably only of a
frame-work or skeleton, or of a fixed casing, which is provided at regular
intervals with screw-threaded holes so that the blocks or matter for printing in
colours can be readily inserted into and removed therefrom.

To this block cylinder there is connected the colouring or inking apparatus F, FI

ollers and may consist of the smallest possible number of rollers, because only
small parts of the block cylinder E are to be inked or coloured at each revolution
of the same. In order to print impressions in various colours at the same time

Having now particularly described and ascertained the nature of our said in-
vention and in what manner the same is to be performed, we declare that what we
claim is:-
(1) Method of producing simultaneously impressions in different colours on rotary
presses, characterized by the fact that at a suitable place in the press there is
arranged a colour-printing-type-cylinder with correspondingly constructed colour-
ing or inking device, which cylinder is operated in any desired manner, and is
provided with a separate printing cylinder, or works together with another type
cylinder upon a printing cylinder, the arrangement being such that the type
cvlinders leave the colour-impressed portions, or the portions which are to be
impressed in colours, free in a suitable manner, as set forth.
(2) For carrying out the method specified in Claim 1, an apparatus charac-
terized by the fact that on the type cylinder B there is arranged a colour printing
cylinder E which is mounted in a double lever M that is pivotted on a pin I, and
which cylinder E, when the printing cylinder B is rotated, is pressed against the

page_text: paper that
passes over the printing cylinder, by means of a carrier H which is fixed
to the said printing cylinder and operates the end k of the double lever M,
substantially as hereinbefore described and shown.
(3) A form of construction of the apparatus specified in Claim 2, characterized
by the fact that the colour printing type cylinder E is driven direct by means of
toothed wheels and is formed on its rib-like or smooth surface with holes 6 for
screwing in, or with any other device for attaching blocks and matter, substantially
as hereinbefore described and shown.
(4) In an apparatus for producing simultaneously impressions in different
colours on rotary presses, a colour box divided into a number of compartments such
as 0, for the reception of different colours, with a roller also divided into corres-
ponding divisions such as P, in which arrangement these divisions dip into the
corresponding compartments of the colour box, as herein before described and
shown.
