Improvements in and relating to Machinery for Printing Partially
in Colours.
1, AMÉDÉE FAYOL, of rue Libottière, Bordeaux, in the Republic of France,
Mechanical Engineer, do hereby declare the nature of my said invention to be as .
follows:-
In the publication of newspapers, reviews and other typographical works, the
advertisements constitute an important source of revenue, which it is constantly
sought to increase; but in order to attain that end, nothing has been heretofore
proposed, so far as I am aware, beyond an increase in the number of advertisements
by increasing the space devoted to them. I propose to attain the end in question
namely, that of increasing the income derivable from a given space devoted to
advertisements, by printing some of such advertisements in colours instead of in the
ordinary black ink. Advertisements so printed will command a higher price than
those printed in black ink only. But this idea can only be practically carried out if
the existing printing machines can be utilized for printing the advertisements in
colours at any required part of the available space, if the printing of the coloured
parts can be effected simultaneously with the printing of the body of the newspaper
or other typographical work; if such printing in colours can be done without
interfering with or retarding the work of applying the composed type or the stereotype
to the printing machine, or the performance of any other operation that may be
necessary for preparing the machine to print, and finally, if the mechanism is not
expensive and does not require frequent repair.
These conditions are fulfilled in the arrangements of mechanism hereinafter
described.
My invention consists, firstly, in means for moving the parts of the composition
intended to print in colours out of the way while the rest of the composition is being
inked with black ink, to move such parts into a position to have coloured ink
applied thereto, and then to move such parts into line with the rest of the composition
so that the whole can be printed from at one time. These means comprise mechanism
placed inside the printing cylinder in rotary printing presses, such mechanism being
so arranged that the centrifugal force resulting from the great speed of the printing
cylinder is utilized for moving the parts of the composition intended to print in
colours in the manner above described. A cam, fixed to the frame of the press, in
combination with an opposing spring, governs these movements correlatively to the
inking appliances and to the printing in black of the rest of the composition. The
same automatic effects are produced in the flat press by means of devices operated
from below the printing form and combined with the working parts of the press.
My invention consists, secondly, in means and processes for facilitating the
formation of the stereotype from the composition so as to reserve in the said
stereotype the opening or openings intended to receive the part or parts of the
composition which is or are to print in colours; also for casting the part of the
composition intended to print in colours and for furnishing the adjusting and attaching
parts thereto. This part of my invention is of great importance because the printing
off of the newspaper or other typographical work must not be delayed or rendered
difficult, and therefore as little change as possible should be made from the usua:
method of working.
My invention consists, thirdly, in a new removeable inking device, which, with its
ink reservoir, its table and its rollers, forms an entire apparatus which can always be
placed in the required position and removed when necessary.
My invention consists, fourthly, in the combination of my removeable inking

page_text: apparatus with the cylindrical printing press, or with the flat printing press, in such
manner that, in either case, any alteration in the existing construction of the machine,
in the method of preparing the machine for work, in the inking of the type or in the
feeding in of the paper, its cutting, etcetera, is avoided.
In the rotary press, there appears to be only one place available for the application
of the necessary apparatus without altering the construction of the machine; it is in
front of the type cylinder and must be easily got at for mounting the stereotypes
on the cylinder and so forth. The construction and actuating devices of my new
inking apparatus enable me to utilize the said position and by reason of the extreme
ease with which the apparatus can be removed the workmen can easily get at the
printing cylinders and all the parts belonging to them. This part of my invention is
therefore characterized not only by the construction of the inking apparatus but also
by the position which it occupies. This novel construction of the inking apparatus
affords similar advantages in its application to flat presses, for it not only allows of
the existing arrangements being preserved, but the traverse of the table is not
increased, nor is the table encumbered during the process of preparing the machine
for work.
1. APPARATUS FOR MOVING THE STEREOTYPES INTENDED TO PRINT IN COLOURS.
a). AS APPLIED TO ROTARY PRINTING PRESSES.
Figures 1 to 6 of the Drawings show one of the arrangements of apparatus I
employ for utilizing the centrifugal force of the printing cylinders to effect the
movement of the carrier supporting the stereotype of the part of the composition
which is intended to print in colour.
Figure 1 is a longitudinal section of a printing cylinder of an ordinary rotary
printing press showing the arrangements of mechanism in question in elevation.
Figure is a longitudinal section of the cylinder and of the aforesaid mechanism.
Figures 3 and 4 are transverse sections taken on the lines 1-2 and 3-4 respectively
of Figures 1 and 2. Figure 5 is an end view taken from the end at which the cam
is placed, and Figure 6 is a partial plan projected from Figure 5.
The printing cylinder a turns with its shaft which passes through the cross
arms a a¹ and is carried in bearings fixed to the frame of the press; it is
perforated to receive the moveable stereotype c and its carrier d which slides
rectilinearly in a box f fixed on the shaft 6 and having its extreme edges let into
the opening in the cylinder a. The box is fixed on the shaft b by a dovetailed
connection on a part of a collar f" fitted on the shaft b and fixed by two screws.
The moveable stereotype is attached securely to its carrier d by means of screws e e¹.
The carrier is formed in one piece with two internal bosses d² which are bored
out to receive a long pin y to which is connected one end (furnished with a suitable
bearing) of a lever h. The other end of the lever his keyed on a shaft k arranged
parallel to the shaft 6 in two collar bearings kk2 bolted on to the shaft b. The end of
the shaft passes out through the end of the cylinder a, and on this outer end is
secured a piece i, a set screw i¹ in which bears against a lever turning loosely on
the shaft ; this lever is furnished with a friction roller which bears against a
cam a fixed to the bearing of the shaft b. A spring pinned on to the inner end
of the shaft k keeps the roller of the lever constantly in contact with the cama,
with a pressure which can be easily regulated by means of the screw which
determines at the same time the strength of the impression in colour by the greater
or lesser projection given by it of the moveable stereotype beyond the general
printing surface.
The shape of the cam is such that the moveable stereotype carrier d is moved so
as to place the face of the stereotype c in a plane below the printing surface A of
the cylinder a when the said surface is to receive a supply of black ink, and in a
plane above the printing surface A of the cylinder a when the moveable stereotype c
is to receive a supply of coloured ink, and in the same plane, or flush with the
printing surface A, when the printing operation is to be performed.

page_text: During the ordinary operation of the machine the cylinder a revolves at great speed,
whereby a centrifugal action is produced which tends to force the moveable stereotype
and its carrier outwards; the cam & governs, regulates or restrains this outward
movement. The spring r forces the moveable stereotype and its carrier, concurrently
with the lever and the cam æ, to make the necessary intermittent movements.
To facilitate the mounting and dismounting of the moveable stereotype and its
carrier, the pin g is placed in the carrier d by means of a long flexible rod j termi-
nated by a plug screwed into a false bottom a² of the cylinder a, which false bottom
forms one bearing for the shaft k. To facilitate the entrance of the pin g into its
bearings and to serve as a guide thereto, a tube 2 is arranged as shown in the drawing,
being held at one end by the cross arm a' of the cylinder and at the other end by the
box f of the moveable stereotype carrier. In order to dismount the moveable stereo-
type carrier, the pin g is drawn out by means of the rod ; and the other pieces are
then easily removed.
Figures 7, 8, 9 and 10 show a modification of the above described arrangement
suitable for cases where the spaco between the shaft band the inside of the printing
cylinder is small.
Figure 7 is a longitudinal section through the axis of the printing cylinder a.
Figure 8 is a transverse section taken on the line 5-6 of Figure 7. Figure 9 is an
end view taken from the end at which the cam is placed and Figure 10 is a detail
view of the collar bearing of the shaft k.
The box f, which contains and guides the moveable stereotype carrier d, is large
enough to allow of the placing between it and the shaft b, but independently of the latter,
of a sort of compound connecting rod or link n for connecting the pin g to the head of
the lever h. This connecting rod or link comprises, as shown, a tee piece jointed to the
pin g, and a fork which embraces the end of the horizontal branch of the tee piece,
and passing balf round the shaft b is connected to the lever h which is keyed on the
shaft oscillating in the collar bearings ¹² and in the false bottom a². Outside this
false bottom the shaft carries the piece i which keeps the lever in contact by
means of the set screw with the cam x in combination with the spring r, and,
normal working, the centrifugal force acting on the carrier d and its stereotype c.
The box is connected to the cylinder a by two countersunk screws and two
tightening screws screwed into the bottom of the box and bearing against the
internal surface of the cylinder.
in
Figures 11 and 12 show a third arrangement in which the fixed cam a pushes
forward a wedge in opposition to a spring r which brings the wedge back.
This wedge slides in slots in the box f and forces outwards the carrier d of
the stereotype c; springs d³ ³ draw the carrier d and its stereotype e inwards as the
wedge is drawn back. The wedge is operated by the rod h the end of which is
furnished with a friction roller 2 acted on by the cam x.
Figures 13 and 14 show a fourth arrangement in which the fixed cam x is placed
in the interior of the cylinder a, and directly in the vertical plane of the moveable
stereotype carrier d. The shaft of the cylinder a is hollow and stopped off at the
place where the cam occurs, it turns on the fixed shaft b' to which the cam is fixed.
The carrier d of the moveable stereotype bears against the cam a by means of
friction roller d* and is pressed thereto by the springs d³ d³.
In completing the description of what relates to the movement of the stereotypes in
rotary printing presses I may remark.
1. That in either of the two arrangements first above described (Figures 1 to 6 and 7
to 10) the same shaft k may actuate one, two or more moveable stereotype carriers ;
that one, two or more shafts k may be employed in the same manner to actuate one,
two or more moveable stereotype carriers, the stereotypes of which are intended to be
placed at different parts of the circumference of the cylinder a.
2. That the came in the arrangement shown in Figures 11 and 12 may act at the
same time on several wedges connected to one rod if they actuate moveable stereo-
types placed on one line parallel to the axis of the cylinder; or it may act successively

page_text: types placed at various points of the circumference of the cylinder a.
3. That the shaft b₁ of the cam x in the arrangement Figures 13 and 14 may carry
several cams if the cylinder a is furnished with several moveable stereotypes c whether
placed in line with one another or not.
(b) As ADAPTED TO FLAT PRINTING PRESSES.
Figure 15 shows a type of flat printing press altered in accordance with my
invention to print in colour by means of the moveable stereotype c simultaneously
with the printing in black by the printing surface A.
The box fis fixed below the form table a, the moveable stereotype carrier & slides in
the said box by means of the lever h keyed on the shaft k; this shaft carries at one
end a lever similar to that shown in Figures 1, 5, and 6, the said lever / having at its
end a friction roller which rolls on a cam surface formed along the frame or bed
plate of the press, so as to cause concurrently with the spring the rising and falling
of the moveable stereotype carrier d. The drawing does not show the lover 7, the cam
surface and the spring r, but those parts will be readily understood by reference to
the arrangements above described and shown in Figures 1 to 6 and 7 to 10.

2. STEREOTYPING THE FIXED AND MOVEABLE PARTS OF COMPOSITION AND
ADJUSTING AND SECURING THE MOVEABLE STEREOTYPE.
Figures 16, 17, 18 and 19 illustrate this part of my invention.
In stereotyping the fixed part of the composition, spaces must be left at prearranged
places for placing the moveable stereotypes. For this purpose I fix mandrils o in the
mould m at the required points, such mandrils having exactly the dimensions of the
moveable stereotypes, so that when the metal is run into the mould these mandrils
form cores which make openings through the stereotype of the exact sizes and in the
exact positions required.
In order to form the necessary openings in the paper mould a block m² (Figures
17 and 18) corresponding in size and shape to the moveable part to be employed and
having cutting edges, as shown, placed in the form when composing. The cutting
edges of this block cut out corresponding openings in the paper when it is pressed
into the type of the composition. If the blows of the brush for beating the paper into
the face of the type are not sufficient to effect this cutting completely, recourse must
be had to a piece of wood and a hammer. The depth of the block m¹ is equal to the
depth of the composition plus the thickness of the paper composing the mould it is
intended to cut through.
The moveable stereotype c (Figure 19) is cast in a moulds, the counterpart s¹ of
which presses the paper mould s² by means of the screw clamps 53. And, as this stereo-
type is to be connected to its carrier d by means of screws, I fix in the mould s
screws or threaded stems q q' which form in the stereotype casting screwed holes, the
pitch, diameter and distance apart of which correspond to the pitch, diameter and
distance apart of the screw e e¹ of the moveable stereotype carrier, Figure 2.
By this method I obtain as exactly as possible, first, the positions of the moveable
stereotypes in the fixed stereotypes; second, the screwed holes for fixing the moveable
stereotypes to their carriers, and third, I avoid trial and error and consequent loss of
time in placing and replacing the moveable and fixed stereotypes.
3. REMOVEABLE INKING APPARATUS.
Figure 20 is a side view of my removeable inking apparatus, Figure 21 a corre-
sponding plan, and Figure 22 a vertical section taken on line 7-8 of Figure 21,
Figure 23 shows the front part of a cylinder printing press on the Marinoni system
with two arrangements of my moveable inking apparatus applied thereto.
Figurs 01:

page_text: Figure 25 shows separately one of the side bearings of the ink receiving and distri-
buting rollers.
The apparatus is carried by a hollow iron shaft B which rests in the open bearings
of two brackets B' fixed on the caps of the bearings of the press cylinders by means
of the same screws or bolts which fix these caps to the frames of the press. The
shaft B has fixed near its ends the heads of two arms D D₁ which form bearings
at the middle of their lengths for the shaft E of the cylindrical inking table
or plate t, and at their lower ends for the shaft F which produces the concentric
to and fro motion of the ink receiving and distributing rollers.
On the two ends of the shaft E of the cylindrical inking table or plate t are placed
loosely two cast iron arms G G₁ furnished with adjusting screws G2 which bear
against the caps of the press bearings, and by which the position of the inking
apparatus, which pivots with the shaft B in the bearings B¹, can be accurately
adjusted. The shaft E is provided with pulleys PP¹ which are driven from the
printing cylinder P by means of the strap P2.
v
The inking apparatus comprises the cylindrical inking table t fixed upon the shaft E,
the ink feeding roller u taking the ink from the reservoir u', the roller which receives
the ink from the roller u and delivers it to the table t, the distributing rollers y y¹
which distribute the ink evenly over the surface of the tablet and the type inking
roller z.
The ink reservoir u¹, its roller u and the type inking roller z are mounted
on two cast iron pieces H H of T shape pinned on to the supporting shaft B. The
journals of the rollers vy y' are carried in bearings in the side pieces L L placed
loosely on the shaft E and connected together by a cross piece M to which is jointed
a crank arm F¹ on the lower shaft F (see Figure 24). This shaft is actuated by
another crank F2 placed at the end of the shaft F and connected by a connecting
rod M to the pin of a crank bolted on the face of a spur wheel R; this spur wheel
is driven by a pinion R' on the shaft 6 of the printing cylinder (see Figure 20). By
these arrangements I am enabled to vary the throw of the crank pin Q, and conse-
quently the extent of the oscillations of the side pieces L L and the alternating
concentric movements of the rollers vy y¹, and to modify the speed of these move-
ments by varying the relative diameters of the spur wheels R R'.
.
The ink feeding roller u, of the ink reservoir, has the usual intermittent rotary
movement imparted to it by means of the ratchet wheel u², the pawl u³ the bearing u
of which is connected by the link u to one of the side pieces L of the the ink receiving
and distributing rollers. The ink receiving roller v has only a movement concentric
with the shaft E of the table t so as to deliver to the said table the ink, which it takes
at the end of its forward stroke from the roller u. The distributing rollers y y', for
equalising and spreading the ink uniformly over the table t, are moved concentrically
to the latter at the same time that they are moved longitudinally to and fro by means
of the two lateral guide pieces H¹ H2. The type inking roller z turns along with the
tablet at a circumferential speed equal to that of the stereotypes on the printing
cylinder.
These arrangements afford great facility for getting at the parts composing the
inking apparatus, for adjusting the apparatus longitudinally and to or from the
printing cylinder, and for removing it and its supports away from the machine
altogether when necessary.
4. COMBINATION OF THE MOVEABLE INKING APPARATUS WITH THE PRINTING PRESS.
It will be understood by reference to Figure 23 that means of getting at the
printing cylinders a a', for the purpose of placing or removing the stereotypes, are
indispensable, and that the devices for feeding the papers must not be interfered with.
My moveable inking apparatus fulfils these conditions, as it may be removed either by
pivotting round the upper supports X to which it may be hung as shown for the
upper inking apparatus, or it may pivot round the lower supports X jointed to the
ends of the workman's seat as shown for the lower inking apparatus. The inking
apparatus may also be removed from the cylinders by sliding in a horizontal plane, or

page_text: by simply lifting it from its supports and carrying it out of the way, as is done in the
case of the ordinary rollers, and if preferred it may be placed behind the printing
rollers.
In the case of a flat printing press of the kind shown in Figure 15 for example,
the moveable inking apparatus is placed between the ink distributing rollers V
and the fixed inking apparatus W, or in any other suitable place in the path
of the form to be inked in colour and suspended for example at the end of
the support Y, or allowed to bear directly on the horizontal bed plate or frame
of the press.
The stops G prevent the inking apparatus from oscillating and
may serve to regulate its height in relation to the plane of the type or stereotype
to be inked.
The composition A to be printed in black is inked by the rollers V and the move-
able stereotype c by the roller =. The inking apparatus is easily removed to allow of
the adjustment of the form etcetera. Its construction and adaptation provide a
practical means of printing in colours without altering the existing machine.
The inking apparatus is operated by the reciprocating carriage of the press. For
this purpose the two driving pullies on the shaft of the cylindrical inking table are
driven by the said carriage, or other reciprocating part of the press, so that the
inking roller will turn to the right or the left according as the cylindrical inking
table itself moves to the right or left. The oscillating motion of the distributing
rollers may be obtained from any constantly revolving part such as from the driving
shaft for example.

COMPLETE SPECIFICATION.
Improvements in and relating to Machinery for Printing Partially
in Colours.
I, AMÉDÉE FAYOL, of rue Libottière, Bordeaux, in the Republic of France,
Mechanical Engineer, do hereby declare the nature of my said invention and in
what manner the same is to be performed, to be particularly described and
ascertained in and by the following statement, reference being had to the four sheets
of drawings filed with my provisional specification and to the letters and Figures
marked thereon that is to say :-
In the publication of newspapers reviews and other typographical works, the
advertisements constitute an important source of revenue, which it is constantly
sought to increase; but in order to attain that end, nothing has been heretofore

1. APPARATUS FOR MOVING THE STEREOTYPES INTENDED TO PRINT IN COLOURS.
(a) AS APPLIED TO ROTARY PRINTING PRESSES.
Figures 1 to 6 of the drawings show one of the arrangements of apparatus I employ
for utilizing the centrifugal force of the printing cylinders to effect the movement of
the carrier supporting the stereotype of the part of the composition which is intended
to print in colour.
Figure 1 is a longitudinal section of a printing cylinder of an ordinary rotary
printing press showing the arrangements of mechanism in question in elevation,
Figure 2 is a longitudinal section of the cylinder and of the aforesaid mechanism,
Figures 3 and 4 are transverse sections taken on the lines 1-2, and 3-4 respectively
of Figures 1 and 2, Figure 5 is an end view taken from the end at which the cam
is placed. and Figure 6 is a partial plan projected from Figure 5.

page_text: The printing cylinder a turns with its shaft which passes through the cross
arms a¹ a¹ and is carried in bearings & fixed to the frame of the press; it is perforated
to receive the moveable stereotype c and its carrier d which slides rectilinearly in a
box fixed on the shaft band having its extreme edges let into the opening in the
cylinder a. The box is fixed on the shaft b by a dovetailed connection on a part
of a collar f fitted on the shaft and fixed by two screws. The moveable stereotype
is attached securely to its carrier d by means of screws e e¹. The carrier d is formed
in one piece with two internal bosses d2 which are bored out to receive a long pin g
to which is connected one end (furnished with a suitable hearing) of a lever h. The
other end of the lever his keyed on a shaft k arranged parallel to the shaft b in two
collar bearings kk bolted on to the shaft b. The end of the shaft k passes out
through the end of the cylinder a and on this outer end is secured a piece i a set
screw ¹ in which bears against a lever turning loosely on the shaft k; this lever / is
furnished with a friction roller which bears against a cam a fixed to the bearing b
of the shaft b. A spring pinned on to the inner end of the shaft k keeps the
roller of the lever constantly in contact with the cam a, with a pressure which
can be easily regulated by means of the screw i¹ which determines at the same time
the strength of the impression in colour by the greater or losser projection given
by it of the moveable stereotype beyond the general printing surface.
The shape of the cam is such that the moveable stereotype carrier d is moved
so as to place the face of the stereotype c in a plane below the printing surface A of
the cylinder a when the said surface is to receive a supply of black ink, and in a
plane above the printing surface A of the cylinder a when the moveable stereotype c
is to receive a supply of coloured ink, and in the same plane or flush with the printing
surface A when the printing operation is to be performed.
During the ordinary operation of the machine the cylinder a revolves at great speed
whereby a centrifugal action is produced which tends to force the moveable stereotype
and its carrier outwards, the cam a governs, regulates, or restrains this outward
movement. The spring forces the moveable stereotype and its carrier, concurrently
with the lever I and the cam x, to make the necessary intermittent movements.
To facilitate the mounting and dismounting of the moveable stereotype and its
carrier, the pin g is placed in the carrier d by means of a long flexible rod j, terminated
by a plug, screwed into a false bottom or end a³ of the cylinder a, which false
bottom or end forms one bearing for the shaft k. To facilitate the entrance of the
ping into its bearings and to serve as a guide thereto, a tube 2 is arranged as shown
in the drawing, being held at one end by the cross arm a¹ of the cylinder and at the
other end by the box f of the moveable stereotype carrier. In order to dismount
the moveable stereotype carrier the pin g is drawn out by means of the rod j and the
other pieces are then easily removed.
Figures 7, 8, 9 and 10 show a modification of the above described arrangement,
suitable for cases where the space between the shaft b and the inside of the printing
cylinder is small.
Figure 7 is a longitudinal section through the axis of the printing cylinder a,
Figure 8 is a transverse section taken on the line 5-6 of Figure 7, Figure 9 is an
end view taken from the end at which the cam a is placed, and Figure 10 is a detail
view of the collar bearing of the shaft k.
The box f, which contains and guides the moveable stereotype carrier d, is large
enough to allow of the placing between it and the shaft b, but independently of the
latter, of a sort of compound connecting rod or link n for connecting the ping to
the head of the lever h. This connecting rod or link comprises, as shown, a tee piece
jointed to the pin g and a fork which embraces the end of the horizontal branch of
the tee piece, and passing half round the shaft bis connected to the lever h which is
keyed on the shaft k oscillating in the collar bearings k¹² and in the false bottom or
end a². Outside this false bottom or end, the shaft k carries the piece i which keeps
the lever in contact by means of the set screw with the cam z in combination
with the spring r, and, in normal working the centrifugal force acting on the
carrier d and its stereotype c.

page_text: and 18) corresponding in size and shape to the moveable part to be employed and
having cutting edges as shown, is placed in the form when composing. The cutting
edges of this block cut out corresponding openings in the paper when it is pressed
into the type of the composition. If the blows of the brush for beating the paper
into the face of the type are not sufficient to effect this cutting completely, recourse
must be had to a piece of wood and a hammer. The depth of the block m' is equal
to the depth of the composition plus the thickness of the paper composing the mould
it is intended to cut through.
The moveable stereotype c (Figure 19) is cast in a moulds the counterpart s¹ of
which presses the paper mould by means of the screw clamps 3; and as this
stereotype is to be connected to its carrier d by means of screws, I fix in the mould s
screws or threaded stems o̟ g¹ which form in the stereotype casting screwed holes,
the pitch, diameter, and distance apart, of which correspond to the pitch, diameter,
and distance apart, of the screws e e₁ of the moveable stereotype carrier Figure 2.
By this method I obtain, as exactly as possible, 1st, the positions of the moveable
stereotypes in the fixed stereotypes; 2nd the screwed holes for fixing the moveable
stereotypes to their carriers, and 3rd, I avoid trial and error and consequent loss of
time in placing and replacing the moveable and fixed stereotypes.
3. REMOVEABLE INKING APPARATUS.
Figure 20 is a side view of my removeable inking apparatus. Figure 21 a
corresponding plan, Figure 22 a vertical section taken on line 7-8 of Figure 21,
Figure 23 shows the front part of a cylinder printing press on the Marinoni system
with two arrangements of my inoveable inking apparatus applied thereto. Figure 24
is a front view of the general arrangement of the inking apparatus, and Figure 25
shows separately one of the side bearings of the ink receiving and distributing
"rollers.
The apparatus is carried by a hollow iron shaft B which rests in the open bearings
of two brackets B¹ fixed on the caps of the bearings of the press cylinders by means
of the same screws or bolts which fix these caps to the frames of the press. The
shaft B has fixed near its ends the heads of two arms D D¹ which form bearings at
the middle of their lengths for the shaft E of the cylindrical inking table or plate t
and at their lower ends for the shaft F which produces the concentric to and fro
motion of the ink receiving and distributing rollers.
On the two ends of the shaft E, of the cylindrical inking table or plate t, are placed
loosely two cast iron arms G G¹ furnished with adjusting screws G2 which bear against
the caps of the press bearings, and by which the position of the inking apparatus,
which pivots with the shaft B in the bearings B¹, can be accurately adjusted. The
shaft E is provided with pulleys P P which are driven from the printing cylinder P
by means of the straps P².
The inking apparatus comprises the cylindrical inking tablet fixed upon the shaft E,
the ink-feeding roller u taking the ink from the reservoir u³, the roller v which
receives the ink from the roller and delivers it to the table t, the distributing
rollers y y¹ which distribute the ink evenly over the surface of the table t, and the
type inking roller z. The ink reservoir u³, its roller u, and the type inking roller z,
are mounted on two cast iron pieces H H of T-shape, pinned on to the supporting
shaft B. The journals of the rollers v, y y' are carried in bearings in the side
pieces L L placed loosely on the shaft E, and connected together by a cross piece M
to which is jointed a crank arm F1 on the lower shaft F (see Figure 24). This shaft
is actuated by another crank F2 placed at the end of the shaft F and connected by a
connecting rod N to the pin Q of a crank bolted on the face of a spur wheel R; this
spur wheel is driven by a pinion R₁ on the shaft 6 of the printing cylinder (see
Figure 20). By these arrangements I am enabled to vary the throw of the crank
pin Q, and consequently the extent of the oscillations of the side pieces L L and the
alternating concentric movements of the rollers vy y¹; and to modify the speed of
these movements by varying the relative diameters of the spur wheels R R³,

page_text: The ink-feeding roller u, of the ink reservoir, has the usual intermittent rotary
movement imparted to it by means of the ratchet wheel u², the pawl u³, the bearing u*
of which is connected by the link u to one of the side pieces L of the ink receiving
and distributing rollers. The ink receiving roller has only a movement concentric
with the shaft E of the table t so as to deliver to the said 'table the ink, which it takes
at the end of its forward stroke from the roller u. The distributing rollers y y', for
equalising and spreading the ink uniformly over the table t, are moved concentrically
to the latter at the same time that they are moved longitudinally to and fro by means
of the two lateral guide pieces H' H². The type-inking roller z turns along with the
table t at a circumferential speed equal to that of the stereotypes on the printing
cylinder.
These arrangements afford great facility for getting at the parts composing the
inking apparatus, for adjusting the apparatus longitudinally and to or from the
printing cylinder, and for removing it and its supports away from the machine altogether
when necessary.
4. COMBINATION OF THE MOVEABLE INKING APPARATUS WITH THE PRINTING PRESS.
It will be understood by reference to Figure 23 that means of getting at the printing
cylinders a a¹, for the purpose of placing or removing the stereotypes, are indispensable,
and that the devices for feeding the paper must not be interfered with. My moveable
inking apparatus fulfils these conditions, as it may be removed either by pivotting
round the upper supports X, to which it may be hung as shown for the upper inking
apparatus, or it may pivot round the lower supports ✗ jointed to the ends of the
workman's seat as shown for the lower inking apparatus. The inking apparatus may
also be removed from the cylinders by sliding in a horizontal plane or by simply
lifting it from its supports and carrying it out of the way, as is done in the case of
the ordinary rollers, and if preferred it may be placed behind the printing rollers.
In the case of a flat printing press of the kind shown in Figure 15 for example,
the moveable inking apparatus is placed between the ink-distributing rollers V and
the fixed inking apparatus W, or in any other suitable place in the path of the form
to be inked in colour, and suspended for example at the end of the support Y, or
allowed to bear directly on the horizontal bedplate or frame of the press. The stops G
prevent the inking apparatus from oscillating, and may serve to regulate its height
in relation to the plane of the type or stereotype to be inked. The composition A, to
be printed in black, is inked by the rollers V, and the moveable stereotype c by the
roller z.
The inking apparatus is easily removed to allow of the adjustment of the
form etcetera. Its construction and adaptation provide a practical means of printing
in colours without altering the existing machine.
The inking apparatus is operated by the reciprocating carriage of the press.
For this purpose the two driving pullies on the shaft of the cylindrical inking
table are driven by the said carriage, or other reciprocating part of the press, so
that the inking roller will turn to the right, or the left, according as the cylindrical
inking table itself moves to the right, or left. The oscillating motion of the dis-
tributing rollers may be obtained from any constantly revolving part such as from
the driving shaft for example.
Having now particularly described and ascertained the nature of my said inven-
tion and in what manner the same is to be performed, I declare that what I
claim is :-
:-
First In rotary printing machinery, the mechanism for printing partially in
colours, consisting of the moveable stereotype carrier d working in an opening in
the printing cylinder a and forced outwards in such opening by the centrifugal
force generated by the rotation of the printing cylinder; but having its movements
governed and regulated by the fixed cam x, shaft k, levers and h, and the spring ",
all combined, arranged, and operating substantially as hereinbefore described, and
illustrated in Figures 1 to 10 of the drawings.
