Improvements in or connected with Ink Ducts of Printing
Machines.
We, FRANCIS CORNWALL TAYLOR, of 2095 Mexican Avenue in the City, County
and State of New York, United States of America, Printer, and JOSEPH COOKE,
of Fargate, Sheffield, in the County of York, Newspaper Proprietor, do hereby
declare the nature of this invention to be as follows:-
The object of our invention, is to construct ink ducts of printing machines in such
a manner that various coloured inks may be fed to the said duct, from which they
are delivered in distinct rows onto the ink table, and our invention is especially
applicable when using various inks preparod as described in the Specification of our
Patent Application No. 8876, A.D. 1896.
According to our invention, we employ the ordinary ink trough having a roller
mounted in the front of samo, and the said roller is provided with a series of rings
which are free to slide longitudinally on the said roller but which are prevented
from turning independently on the roller by a key situated on the latter, which
works in key ways provided in the interior of the rings. Loose separating plates
are provided which are made to fit close to the ink trough, and by opening or
separating the rings, the plates may be inserted between them so as to divide the
trough into a series of compartiments, the width of the said compartments being
determined by the number of rings between the plates. When the rings and plates
have been set in the required positions, they are tightened up along the shaft and
the two outer rings are screwed or otherwise fastened to the roller. A cross rod
or beam is now set in position over the top edges of the plates, thereby firmly
holding same down to their work.
The various coloured inks are fed into the compartments of the trough, and with
the rotation of the roller the rings enclosed in the compartments become covered
with ink and transfer same in the form of bands to the inking roller for transferring
Eame to the ink plate.
The inks having been treated according to the Specification of our Patent
Application previously referred to, do not mix or blend with each other at their
edges, but they remain on the ink plate in straight parallel lines, and as all the rollers
in the machine are mounted at right angles to the line of motion of the ink plate,
the colours are not disturbed in their positions.

We, FRANCIS CORNWALL TAYLOR, of 2095 Mexican Avenue, City, County
and State of New York, United States of America, Printer, and JOSEPH Coокк,
of Fargate, Sheffield, in the County of York, Newspaper Proprietor, 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:-
The object of our invention, is to construct ink ducts of printing machines, in such
a manner that various coloured inks may be fed from the said duct and delivered in
distinct rows onto the ink table, and our invention is particularly applicable when
using various inks,. prepared as described in the Specification of our Patent No. 8876,
A.D. 1896.
In order that our invention may be clearly understood, we will proceed to describe
same with reference to the accompanying drawing, in which similar letters refer to
like parts in both figures.
Fig. 1 is a plan of so much of a machine as is required to illustrate an ink duct
constructed according to our invention, and Fig. 2 is a cross section of same.
According to our invention, we employ an incline A having a shaft B mounted in
front of same. Care rings which are free to slide longitudinally on the shaft B but
which are prevented from turning independently by a key D on the said shaft B,
which key passes through key-ways E situated in the rings C. The rings Cthus
make up a continuous roller, the surface of which works in contact with the front of
the inclino A, thereby forming a trough for the reception of ink. F are separating
plates which fit close to the inclino A, and the front portions of the plates F are so
shaped that they can be inserted between the rings and thus divide the trough into
a series of compartments as seen at Fig. 1, the width of the said compartiments being
determined by the number of rings set between the plates. G are end rings which
are provided with screws H for the purpose of clamping the said rings in position,
and J is a cross rod which may be screwed down onto the plates F by means of the
nuta K situated on pillars Lattached to the framework. M is an inking roller which
is supported on arms from the rocking shaft N, and P is the ink table which has the
usual backward and forward travel common in letter-press machines. The shaft B is
given an intermittent rotary motion, and the inking roller M is alternately raised in
contact with the rings C, and lowered into contact with the ink table P as the latter
passes beneath same, and these motious may be given to the said parts by any
convenient mechanism.
The various coloured inks are fed, into the different compartments of the trough
between the plates F, and with the rotation of the shaft B, the rings C are brought
into contact with the ink in the said compartments and become covered with the
respective coloured inks. As the inking roller M rises into contact with the rings C,
it receives the inks on its surface in the form of a series of bands, each band distinct
from the other. On the passing of the ink table below the roller M, the latter comes
down and transfers the ink on its surface to the said table P in the form of parallel
lines or strips, each strip being distinct from the other. The inks having been treated
according to the Specification of our Patent previously referred to, do not mix or
blend with each other at their edges, but they remain on the ink table in parallel
lines, and as all the rollers in the machine are mounted at right angles to the line of
motion of the ink table, the colours are not disturbed in their positions.
It will thus be seen that the colours may be fed to the ink plate, in such positions

page_text: that they are taken up by the type inking rollers and transferred to the various
lines of type, so as to allow different lines of type to print in different colours,
and this can be effected in ordinary letter-press printing machines with one
impression at practically the same cost and labour as that required for printing in
one colour.
Having now particularly described and ascertained the nature of our said inven-
tion and in what manner the same is to be performed, we declare that what we
claim is :-
1. The rings O and shaft B composing the ink trough roller, substantially as and
for the purposes set forth.
2. The rings C and plates F, whereby the ink trongh is divided into a series of
compartments, substantially as and for the purposes set forth.
3. The combination of the incline A, shaft B, rings C, key D, key-ways E, plates F,
end rings G, screws H, cross rod J, pillars L and nuts K, all substantially as and for
the purposes set forth.
