New or Improved Method and Means for Printing in Several Colours
at One Impression on Rotary Printing Machines.
I, FRANCIS CORNWALL TAYLOR, of 14, Priory Terrace, Sheffield, in the County
of Yorkshire, Printer, do hereby declare the nature of this invention as follows:-
This invention relates to rotary printing machines and consists of new or im-
proved method and means of printing in several colours at one impression on
said machines.
For the sake of example I will proceed to describe my present invention as
carried into practice on and in conjunction with a high-speed rotary printing
machine such as the Hoe machine of the well-known character at present in use.
COLOUR INK DUCT.
In any suitable position advantageously just over the ordinary black ink duct
I provide a table or support on which is mounted an auxiliary ink duct for the
colours.
This colour ink duct is divided in any suitable manner into as many compart-
ments as desired advantageously by means of adjustable partitions or division-
pieces capable of being adjusted in said ink duct so as to thereby enable different
widths of colour to be supplied therefrom exactly as required.
This colour ink duct is advantageously mounted and so arranged as to be
adapted to tilt or be adjusted either laterally transversely or oscillatorily for
instance a frame may be clamped on in any desired position and a duct, duct
roller, and set of ink rollers (for this colour duct) mounted in cheeks or mounts
capable of being moved backwards or forwards in said frame
and capable of tilting.
or
and pivoted therein
With this said colour duct suitable means are provided to slowly (advantage-
ously intermittently) revolve this colour duct roller for instance a crank with
crank connecting rod (advantageously adjustable as to its length by a right and
left-handed screw or otherwise) operates a ratchet to revolve (intermittently or
otherwise) said colour duct roller and suitably toothed wheels in gear with said
duct roller thereby revolve the other ink rollers on this colour duct.
A special colour vibrating roll hereinafter described vibrates between the last
of these colour rollers and the ordinary distributing rolls whereby the colours
are conveyed in stripes to the type or printing surface as hereinafter described.
VIBRATING ROLLER.
The ordinary vibrating roller from the ordinary black ink duct roller to the
distributing roll (or large metal cylinder) operates as before for supplying the
black ink only said vibrating roll is according to my present invention cut away
or reduced in diameter or as I term it "mutilated" along a certain part or parts
of its length so as not to supply any black ink where the coloured inks are to
be applied but otherwise this vibrating roller acts as before.

The large distributing roll or metal cylinder which is laterally vibrated or
reciprocated is used as before only according to my present invention the amount
of said lateral vibration or distance same is caused to reciprocally travel laterally
is greatly reduced or altogether stopped so as not to distribute the stripes of
different coloured inks thereon on to one another as firstly it is necessary to
avoid such lateral distribution of the stripes of coloured ink and secondly no
lateral distribution of the coloured ink is required in carrying out my present
invention.
NEW DISTRIBUTING WAVER" ROLL OR ROLLS.
66
In order to compensate for this reduction or dispensing altogether with the
lateral distribution of the black ink by means of the lateral motion heretofore
imparted to, the main distributing roller or waver as aforesaid according
to my present invention I add one or more new black ink distributing rolls hav-
ing ample lateral motion imparted to same in any suitable manner--this said new
waver roll or rolls being for instance carried by suitable rockers or rocking arms
to which latter reciprocating motion crosswise of the machine (i.c. in the direction
of the longitudinal axis of said roller or rollers) is imparted in any suitable
manner.
This new waver roll or rolls for distributing the black ink according to my
present invention is mutilated or cut away or formed with a smaller diameter
where same passes across the colours (stripes) on the aforesaid large distributing
roller or cylinder so that this new waver roll or rolls having ample lateral recip-
rocating motion imparted thereto will thoroughly distribute or act upon the
black ink on said large cylinder without touching the colours on the other part
of said large cylinder.
COLOUR VIBRATING ROLL.
In order to convey the colour or colours from the aforesaid special colour duct
roller (where the latter is used) to the distributing rolls and thence to the type
or plate or other printing surface-a colour vibrating roll is added and is sup-
ported and operated in any suitable manner advantageously by extending (longi-
tudinally) each end of the rock shaft of the ordinary vibrating roll for the black
ink and then fixing to such extended ends upwardly extending arms or cranks
(i.e. outside the frame of the machine) and in these vibrating arms the said
colour vibrating roll is mounted and when vibrated and pressed against the
colour duct rollers same will receive said colours in stripes (i.e. in rings thereon)
and then when vibrated against the distributing rolls same will only ink the
latter with said colours in corresponding stripes as received from the colour duct
rollers and moreover this colour vibrating roll is out of the way of and will not
come in contact with or convey any black ink-although when arranged and
mounted as above described this colour vibrating roll will vibrate synchron-
ously with the ordinary black ink vibrating roll.
Or this colour vibrating roll may be vibrated in any suitable manner inde-
pendently of said ordinary black ink vibrating roll.
BLACK & COLOURED INK DUCT.
If desired instead of providing a separate and special ink duct divided into
any suitable number of compartments in any suitable manner for the different
coloured inks as hereinbefore described-I may use only one ink duct such as
the ordinary duct or trough for black ink and while using so much of said
trough as is required for black ink I may divide another part of said trough
or duct into several separate, compartments according to the number of colours
required, the division of such ink duct or trough into separate compartments
being effected in any known or suitable manner and by any suitable means.
In such case one vibrating roll may convey the inks from the duct roller or

page_text: set of rollers to the aforesaid distributing roll or large cylinder and any suitable
number of idle rollers or "riders" may be provided for the colour part only-
the lateral distribution of the black ink being effected as before described with-
out lateral distribution of the coloured inks.
New or Improved Method and Means for Printing in Several Colours
at One Impression on Rotary Printing Machines.
1, FRANCIS CORNWALL TAYLOR, a Citizen of the United States of America, resid-
ing at 14, Priory Terrace, Sheffield, in the County of Yorkshire, England,
Printer, 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 rotary printing machines and consists of new or im-
proved method and means of printing in several colours at one impression on
said machines.
For the sake of example I will proceed to describe with reference to the accom-
panying drawings my present invention as carried into practice on and in con-
junction with a high-speed rotary printing machine such as the Hoe machine of
the well-known character at present in use, and the said drawings illustrate so
much of an ordinary high-speed rotary press (having my present invention
applied thereto) as will enable my said invention to be fully and easily under-
stood.
Referring to the drawings:-
Fig. 1 is a view in elevation of the delivery end of the press-the ordinary
folding mechanism being removed.
Fig. 2 is a plan of said delivery end of the machine-each view showing my
present improvements applied.
Fig. 3 is a side view looking in the direction of the arrow 3 Figs. 1 and 2.
Fig. 4 is opposite side view i.e. looking in the direction of the arrow 4 Figs. 1
and 2.
Similar letters of reference indicate corresponding parts throughout.
COLOUR INK DUCT.
In any suitable position-advantageously just over the ordinary black ink
duct AI provide a table B on the supports 131 (fixed to the frame of the
machine) on which is mounted an auxiliary ink duct C for the colours.
This colour ink duct is divided in any suitable manner into as many compart-
ments as desired advantageously by means of adjustable partitions or division-
pieces CC capable of being adjusted in said ink duct so as to thereby enable
different widths of colour to be supplied therefrom exactly as required.
This colour ink duct C is advantageously mounted and so arranged as to be
adapted to tilt or be adjusted either laterally transversely or oscillatorily for
instance end cheeks 1 D may be pivotted at 11 and adapted to be fixed or
clamped firmly by any suitable means in any desired position and the duct C',
duct roller E and set of ink rollers F F F (for this colour duct) are journalled
or mounted in said cheeks or mounts D) and the latter are journalled in the

page_text: frame H capable of being moved backwards or forwards on said table B, while the
duct C, duct roller E and set of ink rollers F F1 F2 in the cheeks D are capable
of tilting as aforesaid so that the colour ink roller F can thus be brought into
any desired position.
With this said colour duct suitable means are provided to slowly (advanta-
geously intermittently) revolve this colour duct roller E for instance a crank
(on a slowly revolving shaft J revolved by the machine) with crank connecting
rod K (advantageously adjustable as to its length by a right and left-handed
screw (not shown) or otherwise) operates a rocker frame L turning loosely on the
shaft of the duct roller E this rocker L carrying a pawl L' pivotted therein and
engaging the ratchet wheel E¹ fixed rigidly on the shaft of the duct roller E
whereby the latter is very slowly revolved and a toothed wheel E* on said roller E
gears with suitably toothed wheels F on the other said ink rollers F F1 F2 and
thereby simultaneously revolve same.
E is a hand wheel fixed on the shaft of the duct roller E by which to turn
the latter by hand if desired.
A special colour vibrating roll hereinafter described vibrates between the last
of the colour rollers F2 and the ordinary distributing rolls P whereby the colours
are conveyed in stripes to the type or printing surface as hereinafter described.
VIBRATING ROLLER O.
The ordinary vibrating roll 0 from the ordinary black ink duct roller A¹ to
the distributing roll (or large metal cylinder) N operates as before for supplying
the black ink only said vibrating roll is according to my present invention cut
away or reduced in diameter or as I term it "mutilated" along a certain part or
parts of its length (.e. so much of this roll may be cut away or of reduced
diameter as corresponds with the larger or thicker portion of the colour vibrating
roll M) so that this roll will not supply any black ink where the coloured inks
are to be applied but otherwise this vibrating roll acts as before.
DISTRIBUTING ROLLER OR "WAVER."
The large distributing roll or metal cylinder N (which is usually laterally
vibrated or reciprocated) is used as before only according to my present invention
the amount of said lateral vibration or distance same is caused to reciprocally
travel laterally is greatly reduced or altogether stopped so as not to distribute
laterally the stripes of different coloured inks thereon on to one another-as
firstly it is necessary to avoid such lateral distribution of the stripes of coloured
ink and secondly no lateral distribution of the coloured ink is required in carry-
ing out my present invention.
NEW DISTRIBUTING "WAVER" ROLL OR ROLLS.
In order to compensate for this reduction or dispensing altogether with the
lateral motion heretofore imparted to the main distributing roller drum or
< waver N as aforesaid according to my present invention (in order to dis-
tribute the black ink on the cylinder N) I add one or more new black ink dis-
tributing rolls having ample lateral motion imparted to same in any suitable
manner this said new waver roll (only one such roll R is shown in the drawings)
being for instance carried by the fixed bearing R¹ at each end and reciprocated
by suitable rocker or rocking arm R² to which latter reciprocating motion cross-
wise of the machine (.e. in the direction of the longitudinal axis of said roller R)
is imparted in any suitable manner for instance by the same motion or mecha-
nism as is at present employed on the well-known Hoe rotary press to produce
the reciprocal traversing motion of the large waver roll or drum such as N.
This new waver roll (or rolls) R for distributing the black ink according to
my present invention is mutilated or cut away or formed with a smaller dia-
meter at R where same passes across the colours (stripes) on the aforesaid large
distributing roller or cylinder N so that this new waver roll R R* having ample

page_text: lateral reciprocating motion imparted thereto the thicker part R will thoroughly
distribute or act upon the black ink on said large cylinder N without the part R
of said roller touching the colours on the other part of said large cylinder N.
It will be obvious that if desired I may form or arrange the roll R R* with
two or more larger portions R thereon of the same or differing lengths and simi-
larly there may be two or more small portions R* at any desired points on the
roll R R*
COLOUR VIBRATING ROLL M.
In order to convey the colour or colours from the aforesaid special colour duct
roller F2 (where the latter is used) to the distributing rolls P and thence to the
type or plate or other printing surface-a colour vibrating. roll M is added and
is supported and operated in any suitable manner advantageously by extending
(longitudinally) each end of the reciprocally revolved shaft Ox of the ordinary
vibrating roll O for the black ink and then fixing to such extended ends upwardly
extending arms or cranks () (i.e. outside the frame of the machine) and in these
vibrating arms the said colour vibrating roll M is mounted and, when vibrated
and pressed against the colour duct rollers F, will receive said colours in stripes
(i.e. in rings thereon) and then when vibrated against the distributing rolls P
will only ink the latter with said colours in corresponding stripes as received
from the colour duct rollers F and moreover this colour vibrating roll M is out
of the way of and will not come in contact with or convey any black ink-although
when arranged and mounted as above described this colour vibrating roll M will
vibrate synchronously with the ordinary black ink vibrating roll O.
Or this colour vibrating roll may be vibrated in any suitable manner inde-
pendently of said ordinary black ink vibrating roll; and this roll M may have
a mutilated or cut away portion M* if desired.
BLACK & COLOURED INK DUCT.
If desired instead of providing a separate and special ink duct C divided into
any suitable number of compartments in any suitable manner for the different
coloured inks as hereinbefore described-I may use only one ink duct such as
une ordinary duct or trough A for black ink and while using so much of said
trough as is required for black ink I may divide another part of said trough or
duct A into several separate compartments according to the number of colours
required; the division of such ink duct or trough into separate compartments
being effected in any known or suitable manner and by any suitable means.
In such case one vibrating roll may convey both the black and coloured inks
from the duct roller or set of rollers to the aforesaid distributing roll or large
cylinder N and any suitable number of idle rollers or riders" P may be pro-
vided for the colour part only-the lateral distribution of the black ink being
effected by means of the new waver roll R R* as before described without lateral
distribution of the coloured inks.
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. The herein-described method of printing in several colours at one impres-
sion on a rotary printing machine which consists in conveying the black and
coloured inks respectively to different parts of the ordinary large distributing
roller or waver such as N, reducing or dispensing altogether with lateral
reciprocal motion of the latter, and distributing the black ink on said cylin-
" waver
or
der N by means of the new and mutilated roll
"such as R R* recipro-
cated laterally and adapted to distribute the black ink by means of the larger
portion R thereof while the smaller part R* thereof is quite clear of the coloured
ink substantially as and for the purposes set forth.
2. In a rotary printing machine provided with an ink duct adapted to be

page_text: divided into a number of separate compartments for the various inks required
for printing in several colours at one impression, the combination with the old
waver or large distributing roll such as N of the new laterally reciprocated
waver" roll such as R R* of two (or more) diameters the smaller part (or parts)
being formed and adapted to pass clear of the inks on the cylinder N and the
larger part R being adapted to distribute only the black ink on said cylinder N
substantially as and for the purposes herein before set forth.
3. In a rotary printing machine the combination with the ordinary black
ink duct of an auxiliary ink duct adapted to be divided into a number of separate
compartments for the various coloured inks to be used for printing in several
colours at one impression, a vibrating roll for the black ink an auxiliary vibra-
ting roll for the coloured ink and both vibrating rolls conveying their respective
inks in stripes to different parts of a large distributing roll such as N not later-
ally reciprocated, a mutilated roll or new waver roll supported in contact with
said large roll N and adapted to be reciprocated transversely thereof the large
part such as R bearing against and distributing the black ink on the cylinder N
while the smaller or cut away portion R* of this new roll R R* reciprocates out
of contact with said cylinder so as to be clear of the coloured inks thereon all
arranged and operating substantially in the manner and for the purposes set
forth.
4. Rotary printing machines of the character specified constructed combined
and arranged to act substantially in the manner and for the purposes herein-
