page_text: LETTERS PATENT to John Trafalgar Waight, of 7, Anstey's Row, Essex Road,
Islington, in the County of Middlesex, for the Invention of "IMPROVEMENTS
IN THE METHOD OF AND APPARATUS FOR APPLYING SEVERAL COLORS TO A
Surface at the same Time,”
Sealed the 16th March 1880, and dated the 22nd September 1879.
PROVISIONAL SPECIFICATION left by the said John Trafalgar Waight at
the Office of the Commissioners of Patents on the 22nd September 1879.
JOHN TRAFALGAR WAIGHT, of 7, Anstey's Row, Essex Road, Islington, in the
County of Middlesex. "IMPROVEMENTS IN THE METHOD OF AND APPARATUS
FOR APPLYING SEVERAL COLORS TO A SUrface at the SAME TIME."
This Invention consists of a new method of inking or coloring a forme of types,
stone, or any other surface, with two or more colors at the same time, with one and
the same inking roller or rollers, by means of a special apparatus. The apparatus
consists of a rectangular table made of iron or some other suitable material; Fig. 1
is a plan of the top of such table; it is divided by narrow strips of iron a, a, into
as many divisions e as there are colors required. These strips run parallel to the
edges a, b, & c, d, of the table; along the edge b, d, of the table, and parallel to
such edge, are placed as many ink ducts b, b, b, as there are divisions e in the table.
These ink ducts may be in all respects similar to the ink ducts used on all ordinary
cylinder printing machines; they are placed side by side in the same line, as shewn
in the plan. In front of each ink duct is a horizontal circular plate or disc
marked c in the plan; each disc revolves on its own axis, and is made by means
of a rod and ratchet motion to turn a certain part of a revolution each time the
distributing roller d, hereinafter referred to, passes over it. The tops of the discs
should be slightly above the level of the strips marked a; and these strips are
themselves slightly higher than the top of the table, so that the spaces they divide
form separate beds or channels e, e. In these beds and at right angles to the
strips a, a, are placed pieces of wood, iron, or other material, hereinafter called
tablets (marked ƒ in the plan) of such a height that the tops thereof, which are
planed or otherwise rendered even, are level with the tops of the discs c, c, c.
These tablets f, f, are arranged in the several beds or channels e, e, at such
distances from the edge a, c, of the table, & in such a manner as that one or
[Price dı

page_text: more of them may correspond with the lines of type or parts of the surface to be
colored, and they are retained in their places by screws, clamps, or any other
efficient means. The distributing roller d travels to and from the ink ducts b, b, b,
from and to the edge a, c, of the table on guides affixed to the edges a, b, and c, d,
of the table. A portion of the carriage in which this roller runs is a cone or camb,
which actuates the rod and ratchet motion, causing the discs c to revolve in an
ordinary manner, as previously mentioned. The roller d having been charged with
inks or colors from the ducts b, b, b, distributes the same on the discs c, and then
imparts the said colors to the tablets f, the tablets in each division of the table being
supplied with that ink or color which is in the duct corresponding to such
division.
G is an inking roller, it runs in a carriage without oscillation from the edge c, d,
of the table, and in a path at right angles to such edge over all the tablets f, and
thence on to the types or other surface to be inked or colored. As this inking
roller passes over the said tablets it takes up some of the ink or color which has
been deposited on them respectively by the distributing roller d, as before explained,
and in this manner becomes endued with a series of rings or belts of colors, of
widths corresponding to the respective tablets from which it has derived the same,
and it imparts the colors to the types or other surface in stripes corresponding to
such rings or belts.
Should it be required to ink or color any lines of type or surface, or curved lines
or ornaments, at right angles to the stripes made by the inking rollers as just
described, I perform the same in the following way :-
In one or more of the channels or beds e I place tablets f parallel to the
types a, a, instead of at right angles thereto, and I make the size of the inking
roller such that by one revolution thereof the ink or color taken up from such
parallel tablets shall be deposited on the lines to be inked. The ordinary measures
must be adopted to ensure that the inking roller shall not make more or less than a
complete revolution in covering a plain surface equal in length to the circumference
of the roller.
I claim, first, the method of dividing the ink table transversely into sections or
divisions, as described; secondly, the arrangement of the tablets therein, as
described; and, thirdly, the whole arrangements of the. tablets, discs, ink ducts,
distributing and. inking rollers, as before described, and as applied to the inking or
or coloring of types or other surfaces requiring to be colored..

an Order of the Lord Chancellor, filed by the said John Trafalgar Waight in
the Great Seal Patent Office on the 2nd April 1880.

"IMPROVEMENTS IN THE METHOD OF AND APPARATUS FOR APPLYING SEVERAL
COLORS TO A SURFACE AT THE SAME TIME."
This Invention consists of a new method of inking or colouring a forme of types,
stone, or any other surface, with two or more colours at the same time, with one
and the same inking roller or rollers, by means of a special apparatus.
The apparatus consists of a rectangular table made of iron or some other suitable
material; Fig. 1 is a plan of the top of such table; it is divided by narrow strips
of iron a, a, into as many divisions E as there are colors required. The strips run
parallel to the edges A, B, and C, D, of the table along the edge B, D, of the table,
and parallel to such edge are placed as many ink ducts b, b, b, as there are divisions
in the table. These ink ducts may be in all respects similar to the ink ducts used
in all ordinary cylinder printing machines; they are placed side by side in the
same line, as shewn in the plan. In front of each ink duct is a horizontal circular
plate or disc marked c in the plan; each disc revolves on its axis by means of a
rod & ratchet motion, and turns a certain part of a revolution each time the
distributing roller D, hereinafter referred, to passes over it. The tops of the discs
should be slightly above the level of the strips marked a; and these strips are
themselves slightly higher than the top of the table, so that the spaces they
separate form separate beds or channels E, E, E. In these beds and at right angles
to the strips a, a, are placed pieces of wood, iron, or other material (hereinafter
called tablets, and marked F in the plan) of such a height that the tops of them
being planed or otherwise rendered even are level with the tops of the discs c, c, c.
These tablets f, f, are arranged in the several beds or channels E, E, E, at such
distances from the edge of the table A, C, in such a manner that one or more of
them may correspond with the lines of type or parts of the surface to be colored,
and they are retained in their places by screws, clamps, or any other efficient
means. The distributing roller D travels to and from the ink ducts b, b, b, from
and to the edges A, C, of the table on guides affixed to the edges A, B, & C, D, of
the table. A portion of the carriage in which the roller D runs is a cone or camb,
which actuates the rod and ratchet motion, causing the discs C to revolve in an
ordinary manner, as previously mentioned The roller D having been charged with
ink from the ducts b distributes the same on the discs c, and then imparts the said
colors to the tablets f, the tablets in each division of the table being inked with
that color or ink which is in the duct corresponding to such division.
G is an inking roller, it runs in a carriage without oscillation from the edge C, D,
of the table, & in a path at right angles to such edge over all the tablets, and
thence on to the types or other surface to be inked or colored. As this inking
roller passes over the said tablets it takes up some of the ink or color which has
been deposited on them respectively by the distributing roller D, as before
explained, and in this manner becomes endued with a series of belts of rings of
colors, of widths corresponding to the respective tablets of which it has derived
the same, and it imparts the colours to the types or other surface in stripes
corresponding to such rings or belts.
Should it be desired to ink or color any lines of type or surface at right angles to the
stripes made by the inking roller, as just described, I perform the same in the following
way: In one or more of the channels or beds EI place tablets f parallel to the
strips a, a, instead of at right angles thereto, and I make the size of the inking
roller such that by one revolution thereof the ink or color taken up from such
parallel tablets shall be deposited on the lines to be inked. The ordinary measures

a complete revolution in covering a plane surface equal in length to the circumference
of the roller.
I claim, first, the method of dividing the ink table transversely into sections or
divisions as described; secondly, the arrangement of the tablets therein as
described; and, thirdly, the whole arrangement of the tablets, discs, ink ducts,
distributing rollers, and inking rollers, as before described, and as applied to the
inking or colouring of types or other surfaces requiring to be colored.
In witness whereof, I, the said John Trafalgar Waight, have hereunto set my
hand & seal, this 22nd day of March, in the year One thousand .eight
hundred and eighty.
