COMPLETE SPECIFICATION (AMENDED).
Apparatus for Printing Simultaneously in Various Colours.
I, FERDINAND VON EULENFELD, of 51, Friedrichstrasse, Breslau, in the
German Empire, Merchant, 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 relate's to apparatus for printing simultaneously in various
colours.
According to my invention I employ separate cylindrical movable type carriers
for those parts of the matter or composition which are to be differently coloured,
the said carriers being operated by any suitable means such as, for instance, by the
inking rollers designed to ink the type for printing the remaining portions of the
matter or composition and being each provided with a special inking arrangement
for supplying the type with the desired colour.
My movable type carriers are not operated directly by the inking rollers as the
type carriers must remain free from the colour on the inking rollers, but for this
purpose intermediate devices are employed. The said devices, which are contained
in the frame holding the type carriers and the inking arrangements for the type,
consist of rollers or the like adapted to be pressed downwards, and actuated by the
inking rollers of the press or printing machine, the said rollers themselves operating
other devices which actuate the type carriers.
The whole arrangement is held in a frame which is arranged in the forme
between the ordinary type in such a manner that the faces of the movable type are
in the same plane as those of the ordinary type. The number of type carriers
depends entirely on the number of letters or words which it is desired to print in
different colours. If desired each word can be printed in a different colour, or even
cach letter or a combination of these two methods can be employed.
The type carriers are preferably arranged on horizontal axes and are connected
together by toothed wheels, for instance, so that when motion is imparted to one of
the said carriers it will be transmitted to the others, that is to say, motion will be
transmitted from the above mentioned rollers or the like which are adapted to be
pressed downwards, to those type carriers, which are arranged to move all the
others, by means of one or more ratchet wheels and pawls whereby an intermittent
movement is imparted to the type carriers.
As each of the inking rollers imparts an intermittent motion to each (if there are
more than one) of the rollers adapted to be pressed downwards, the number of
ratchet teeth in each ratchet wheel must have a certain relation to the number of
rollers to be pressed down and to the number of inking rollers in the machine in

page_text: order to ensure that the type carried in the movable carriers is inked with the
proper colour simultaneously with the inking of the ordinary type by the inking
rollers of the machine, that is to say, to ensure that the type carriers make one
complete revolution during the time employed in inking the ordinary type.
From the foregoing it is evident that the chief characteristic of my invention is
the employment of a frame which is inserted in the forme of a printing machine,
the said frame having one or more movable type carriers, each being provided
with a separate inking device; suitable means being employed for actuating these
parts.
Instead of employing the inking rollers of the press to actuate my apparatus
I could employ other rollers or I could provide projections on the frames, of the
inking rollers or on other travelling parts of the press.
To enable my invention to be fully understood I will describe the same by
reference to the accompanying drawings, in which:-
Figure 1 is a plan of my colour printing apparatus :
Figure 2 is a plan of the inking arangement:
Figure 3 is an underside view of the apparatus with the inking arrangement
removed:
Figure 4 is a section on the line 4-4 of Figure 1.
Figure 5 is an elevation of a suitable arrangement of mechanism for actuating
the type carriers :
Figure 6 is a plan of my apparatus adapted for use with cylinder printing
machines:
Figure 7 is a section on the line 7-7 of Figure 6.
a represents the frame to be inserted in the forme of the printing machine, the
said frame being shewn in Figures 1 to 5 provided with eight type carriers b for
letters and five type carriers 6 for words. These type carriers b, band b₁, are
connected together by toothed wheels c and d and the two sets b and 61 are
connected by the bevel wheels, so that the type carriers are caused to rotate
on their axes d, d simultaneously. The axis of the type carrier lying next to
the type carriers is provided with two ratchet wheels e, c¹ actuated by the
pawls f, and held in position by the spring detent e². The pawl f is fixed to a
lever pivoted at 1 to the frame a and the pawl fi to a lever g² pivoted to the
frame a at g³. Both of these levers are provided with or form at their free ends a
bearing g' for one of the pivots hº of the rollers h which are adapted to be pressed
downwards. In the drawings two such rollers are shewn arranged at the smaller
sides of the frame a and projecting sufficiently far above the same to enable the
inking rollers of the machine to actuate them, that is to say, to press them
downwards. The other pivot of each of these two rollers h, h is held by a
lever i pivoted at i¹ to the frame a and provided with a spring which tends to
keep the said pivot in its highest position. Similar springs act in a similar
manner on the levers g and g² carrying the pawls.
If, now, it be supposed that the printing machine is provided with six inking
rollers the latter will, in passing once backwards and forwards, press on the two
rollers h, so that each of the pawls f, fl will be actuated twelve times and each
of the type carriers twenty-four times and all the type carriers 6 and 61 will make
one complete revolution the ratchet wheels e and e¹ being provided with the
required number of teeth for that purpose. In this rotation the type in the type
carriers come in contact with inking rollers k and the number of which is equal
to that of the type carriers 6 and 6. The inking rollers and are arranged so
as to give under pressure either by means of spiral springs which are arranged
within the ink reservoirs 1, 2 or by means of flat springs which act on the pivots
of the inking rollers which project through the side walls of the said reservoirs / or
by any other suitable means. Each type carrier can be provided if desired with
two inking rollers arranged in the usual manner.
The above described arrangement is adapted for ordinary platen or other
printing presses whilst Figures 6 and 7 represent an arrangement adapted for use

page_text: with cylinder machines. In this arrangement the frame a is made to fit the curve
of the periphery of the cylinder. As the cylinder in such machines is encircled
with stereotype casts from the type it is therefore necessary when employing my
invention with such machines to provide the stereotype plate with a recess in which
the frame a can be received. For this purpose I provide a small receptacle a¹ in
the said plate the interior of which forms the recess in which the frame a is received
and held by a suitable spring catch m.
With regard to the simultaneous action of the pawls f, f¹ and the ratchet
wheels c, e I may remark that the mechanism can be so arranged that the
movement of the pawls can be altered for the purpose of enabling the arrangement
to be used with presses having a different number of inking rollers (or of parts),
which actuate the apparatus.
Having now particularly described and ascertained the nature of my said in-
vention and in what manner the same is to be performed, I declare that what I
claim is:
1. Apparatus to be used with printing presses or printing machines for the
purpose of printing simultaneously in two or more colours, consisting of one or
more rotatable type carriers, arranged in a frame adapted to be placed between the
ordinary type and in which one or more separate inking devices for the rotatable
types are arranged, the said type carriers being rotated by a travelling part of
the machine so that they are first brought into contact at the proper time with
the said inking devices and are then brought into position for printing substan-
tially as herein before described.
2. Apparatus of the kind described in Claim 1 in which devices such as rollers
are arranged in the frame, which devices are operated by the machine and which
themselves actuate the type carriers by suitable intermediate mechanism substan-
tially as described.
3. Apparatus of the kind described in Claim 1 in which the type carriers are
pivoted on horizontal axes and are connected with devices, adapted to be pressed
downwards, by means of ratchet wheels and pawls so that the rotation of the type
carriers for the purpose of inking the type in the same is effected intermittently,
substanially as described.
4. In apparatus of the kind described curving the bottom of the frame as shewn
in Figure 7, in combination with a corresponding curved receptacle as, and for the
purpose, described.
5. The manufacture and use of the improved colour printing apparatuses
hereinbefore described and illustrated respectively in Figures 1 to 5 and 6 and 7
of the accompanying drawings.
