ARTHUR CHARLES HENDERSON, of 6, Southampton Buildings, Holborn, in the
County of Middlesex, Patent Agent. " IMPROVEMENTS IN PRESSES FOR PRINTING
IN COLOURS." A communication froin abroad by Israel L. G. Rice, of the City of
Cambridge, County of Middlesex, State of Massachusetts, and Charles Brigham, of
the Town of Watertown, County of Middlesex, aforesaid, in the United States of
America.
The object of this Invention is to furnish an inking apparatus for printing presses,
by means of which several colours may be printed from a single form of type at one
impression.
The Invention consists of sectional ink tables having rotating disks placed in
them in combination with sectional ink fountains.
The tables are placed on a frame on the printing press, and are arranged to cor-
respond to the various lines of type that are to be printed in different colours. They
are secured in place by means of set screws placed on their ends.
The disks in the tables have their surfaces even with that of the tables. Mitre
gears on the stem of the disk work with gears on a shaft passing underneath the
table. A screw. gear is placed on the end of this shaft, and is worked by a screw
running at the back end of the tables. This distributes the ink on the tables, as
inking rollers continually pass and repass over the tables. To keep the tables
supplied with ink sectional ink fountains are arranged to correspond with the ink
tables.
Tables and fountains are made of various widths so as to be readily adapted to
the various widths of the lines of types. The sectional ink fountains have their

a shaft having a spline; this shaft is turned by the ordinary mechanism of the press
being put in connection with it.
SPECIFICATION in pursuance of the conditions of the Letters Patent filed by
the said Arthur Charles Henderson in the Great Seal Patent Office on the 9th
July 1877.

The object of this Invention is to furnish an inking apparatus for printing presses,
by means of which several colours may be printed from a single form of type at one
impression
The Invention consists of sectional ink tables having rotating disks placed in them
in combination with sectional ink fountains.
Fig. 1 is an elevation; Fig. 2, a plan of the improvements embodying my Inven-
tion. These tables J, J, are placed on a frame S, S, on the printing press, and
are arranged to correspond to the various lines of type that are to be printed in
different colours. They are secured in place by means of the set screws T, T, placed
on their ends.
The disks K, K, in the tables have their surfaces even with those of the tables
J, J. Mitre gears L, L, on the stein of the disk work with gears M, M, on a shaft o
passing underneath the table. A screw gear P is placed on the end of this shaft,
and is worked by a screw Q running at the back end of the tables. A revolution
of this long screw turns the disks in the tables. This distributes the ink on the
tables, as inking rollers R, R, continually pass and repass over the tables. To keep
the tables supplied with ink sectional ink fountains A, A, are arranged to correspond
with the ink tables.
Tables and fountains are made of various widths so as to be readily adapted to
the various widths of the lines of type.
The sectional ink fountains have their rollers B, B, provided with a hole B¹,
having a keyway cut in it. Through these holes is put a shaft B2 having a spline;
this shaft is turned by the ordinary mechanism of the press being put in connection
with it.
Further details are unnecessary, as all that can properly claimed be as new is the
following, that is to say:-I claim the combination of sectional ink tables having
rotating disks inserted in them in combination with sectional ink fountains, substan-
tially as in the manner and for the purposes herein set forth.
The ink is conveyed from the sectional fountains to the sectional tables by
means of an inking roller F that comes in contact with the rolls in the fountains
and with the tables at F¹. D is a scraper to remove the superfluous ink from the
roller B; C is a screw for adjusting the scraper; E is a screw for securing the
fountain in its proper place; I is a slotted guide that the inking roller F passes in.
In witness whereof, I the said Arthur Charles Henderson, have hereunto set
my hand and seal, this Ninth day of July, in the year of our Lord One
thousand eight hundredand seventy-seven.
