Improvements in Inking Arrangements for Chromatic Printing.
I, ROBERT ERNST FISCHER, of the City of Barmen, Wertherhofstrasse 3, Rhenish,
Prussia, Germany, Manufacturer, 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 new and useful improvement in inking apparatus
for chromatic printing adapted for rotary and other printing machines, which
permits the printing of a sheet in different colors in one operation and in such a
manner that the colors may be changed and varied at pleasure. I attain the
named purpose by a very simple constructed inking apparatus which is shown
on the accompanying drawing in two modifications.
Figure 1 is a cross section; Figure 2 a longitudinal view of the first arrange-
ment; Figures 3 and 4 are similar views of the second construction.
In said figures the several parts are respectively indicated by reference numbers
as follows. a is an ink supplying roller of a common rotary or other printing press,
which is located in the receptacle of generally known construction, and which is
provided with an adjustable bottom plate c.
In said receptacle I arrange a number of ink fountains consisting of a box d,
which has two side walls a back wall and a bottom. The bottom of said box
corresponds exactly with that of the receptacle so that when the boxes are placed
in the receptacle they fit closely therein. The roller forms then the front wall
of the boxes, which are filled with different colored ink, that is supplied to the
roller and from it by intermediate rollers to the form cylinder.
Now the side walls of the boxes are made as small as possible so that the
colours may be easily blended on the roller and there cannot be recognised a
free space between two colors. The latter can then be varied by changing the
fountains or by removing them at pleasure or by placing more or less boxes in
the receptacle equal or of different latitude.
The chromatropes thus produced do not differ in any way from those made in
more than one operation and by other printing or lithograph methods. In the
modification shown in Figures 3 and 4 the boxes d are replaced and instead of
them there are arranged diaphragms e, which fit closely into the receptacle and
divide the same in a number of fountains, which are filled with different inks in
crder to act as before.
The diaphragms are held in position in the following manner:
To the receptacle 6 is fastened by means of angle supports y a bar f, which is
slotted lengthways so as to take up forked pieces h, that seize the diaphragms and
hold them fast. The forked pieces are provided with screw and nut so that they
may be screwed to the bar. They are provided also with a spring i, which presses
on the upper edge of the diaphragms in order to press them tightly on the cir-
cumference of the supplying roller a. By removing, reducing or multiplying the
diaphragms there may be also attained plenty of variations of the colours.
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. A chromatic inking device consisting of a number of fountain boxes, having

page_text: 3 vertical walls and a bottom so arranged as to closely fit into the receptacle of a
printing press for the purpose as described and set forth..
2. A chromatic inking device consisting of a receptacle being divided by
diaphragms in a number of colour fountains, which are removable and adjustable
by means of a bar f forked pieces 6 and a pressing spring i all for the purpose as
described and set forth.
