Improvements in and connected with the Inking Apparatus for
Printing Machines.
I, HENRY EDWARD NEWTON, of the Office for Patents, 6, Breams Buildings,
Chancery Lane, in the County of London, Patent Agent, 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 certain improvements in inking apparatus.
In operating printing machines, it is desirable, when the machine is started,
to allow it to run for a certain period with the inking device in full operation, but
without permitting the form rollers to come in contact with the form, the object
being to cause the ink to become thoroughly broken up and mixed on the several
form distributing rollers, and on the ink distributing surface or table, so as to
obtain an even and thorough distribution of the ink throughout the inking
apparatus.
Furthermore, in inking apparatus as usually constructed, there are provided
sets of rollers which run in direct contact with the form, and the purpose of which
is to apply ink to the form. These form rollers receive the ink from the sources
of ink supply in various ways, and there are used, in connection with them,
additional rolls, which are termed vibrators. These vibrators run in contact with,
and usually ride upon the form rollers, and they have, in addition to their
rotating movement, a lengthwise reciprocating movement or a movement in the
direction of their axes. The purpose of these vibrators is to thoroughly mix,
break up, and distribute the ink on the form rollers, so that the latter may apply
a smooth and even coat of ink to the form.
The shafts of the form rollers are loosely mounted in their bearings, so that
they may run freely and easily over the form, and, in order that the rollers may
run with as little friction as possible, a slight space is left between the collars
on the shafts and the bearings. This permits the form rollers to shift slightly
in a lengthwise direction. As the vibrators, which, as has been before said,
ride upon the form rollers, are reciprocated over them, they will therefore produce
a slight lengthwise movement of these rollers, also, although they are intended
to have only a rotary movement, and as the press is used, and the shafts wear in
their bearings, the amount of this lengthwise movement increases.
It has been found that this lengthwise movement of the form rollers, although
it is slight in itself, is sufficient to rub or wear the printing surfaces of the form
with which the form rollers run in contact, this being more particularly true
where the forms are of a planographic character. The lines of the design to be
printed, therefore, instead of retaining that clearness and sharpness of outline
which is necessary to rood printing, become, after continued use, somewhat worn
and blurred.

page_text: It is one of the objects of this invention to provide means whereby the machine
may be run for any desired length of time to thus mix and thoroughly distribute
the ink, and to do this without permitting the inking devices to come in contact
with the form. The ink from the fountain is thus carried to, and thoroughly
distributed and mixed upon the distributing surface and form rollers, so that au
even distribution of ink upon the form may be had as soon as the printing is
begun.
A further object of the invention is to provide means whereby the impression
cylinder may be locked against movement during the time when the machine is
run, for the purpose of distributing the ink as above stated.
A further object of this invention is to construct an inking mechanism in which
the blurring or wearing away of the design by the lengthwise movement of the
form rollers shall be avoided.
With these and other objects in view, the invention consists in certain parts,
improvements, and combinations, as will be hereinafter described and more fully
pointed out in the claims hereunto appended.

which like characters of reference indicate the same parts:-

The machine which has been selected to illustrate the concrete embodiment
of the invention, is a multi-color machine of the rotary type. In this machine, I
indicates the frame of the machine. The frame is provided with suitable
recesses, in which are located boxes 3, 3, which carry the shafts 4, 4, of the
form-carrying cylinders 5, 5, and boxes 6, which carry the shaft 7 of the impres-
sion cylinder 8. The boxes may be held in position by bars 10, which may be
secured in any suitable manner to the frame of the machine.
The frame is provided with suitable bearings 11, in which is journaled a power
shaft 12, the power shaft being provided with any suitable means of driving it,
as, for instance, a power or pulley wheel 13. The power shaft 12 carries a
gear 14, which meshes with a gear 15 on a short shaft 16, which is suitably
journaled in one side of the frame, this short shaft and gear being on the side
opposite to the observer in Fig. 1. This short shaft.16 carries a gear 17, through
which power is communicated to the impression cylinder, in a manner to be
described hereafter.
On the impression cylinder shaft 7 is loosely mounted a gear 18, which is in
mesh with the gear 17. This gear is in mesh with and drives gears 19, which
are fast on the shaft 4 of the form-carrying cylinders, and by which, therefore,
these form-carrying cylinders are driven.
The impression cylinder is provided with a locking device by which it may
be secured to and driven from the gear 18, or may be disconnected therefrom,
when it is desired to run the machine, for the purpose of inking up as heretofore
described.

page_text: The locking device which connects the cylinder 8 to the gear 18 may be
variously constructed. Preferably, however, the cylinder is provided with a
shaft 20, which is or may be suitably journaled in the spokes of the cylinder, or
mounted thereon in any convenient way. This shaft 20 carries at one end a
locking arm 21, which is fixed on the shaft, and which engages a cooperating
locking member carried or formed on the gear. This co-operating member might
be made in various ways, but it is preferably a notch 22 formed in the rim of the
gear 18. The shaft 20 preferably carries at its opposite end a locking arm 23,
which is also fast on the shaft, and which engages a co-operating locking member,
which may also be variously formed, but is preferably a notched block 24, which
is carried on any suitable part of the frame. It is herein shown as mounted on
the part 1 of the frame which carries the feed and delivery devices. The arms 21
and 23 are so arranged that when the arm 23 engages the notched block 24 on
the frame, the arm 21 will be disengaged from the notch 22 in the gear, and
when the arm 21 is engaging the notch 22, the arm 23 will be disengaged from
the notched block 24. It follows, therefore, that when the arm 21 is engaging
the notch 22, the impression cylinder will be locked fast to the gear 18, and will
rotate therewith. When however the arm 21 is disengaged from the notch 22,
and the arm 23 is engaging the block 24, the impression cylinder will be dis-
engaged from the gear, and locked fast to the frame, in which position of the
parts the gear 18 is free to revolve without revolving the impression cylinder.
The shaft 20 may be rocked in various ways, in order to produce the movements
of the locking arms before described. Preferably, however, the shaft will be
provided with a segmental arm 25, which is fast on the shaft 20. This segmental
arm engages a worm 26 on a short shaft 27, which is or may be mounted in a
bearing 27, suitably secured to the impression cylinder. This shaft carries a
worm wheel 28, which is engaged by a worm 29 on another shaft 30, suitably
mounted in the cylinder. When the shaft 30, therefore, is rocked in either
direction, the shaft 20 will be correspondingly rocked, to produce the desired
movement of the locking arms.
The shaft 30 may be rocked in any suitable manner. In the drawings it is
shown as provided with a square head 31, on which a wrench may be placed.
The impression cylinder 8 is provided with an impression surface 32, and with a
low portion 33, said portion being slightly nearer the axis of movement of the
impression cylinder, so as to pass the form and ink distributing surfaces of the
form cylinders without touching them, this being a well understood feature of
construction of this type of machine.
The locking block 24 is so arranged on the frame that when the impression
cylinder is locked to it, its impression surface 32 will be turned away from the
printing and ink distributing surfaces of the form-carrying cylinders 5. The
gear 18, therefore, when it is disconnected from the impression cylinder, can
rotate the form-carrying cylinders 5, without danger of any portion thereof touch-
ing the impression cylinder, the portion 33 of said cylinder being arranged as
before described, nearer the centre of rotation of said cylinder, and consequently
in such position that it will not touch either of the form-carrying cylinders.
The form carrying cylinders 5 are provided with form-carrying surfaces 34 and
ink-distributing surfaces 35. The ink is carried from a fountain F through the
usual ductor and distributing rolls, to a series of form-inking rollers I. These
rollers are journaled in slotted open bearings in stationary plates 36, which may
be suitably secured to the frame on each side of each form-carrying cylinder.
Various means may be provided to prevent the form rollers from coming in
contact with the printing surfaces, when the machine is being run for the purpose
of inking up, and at the same time permit said rollers to come into contact
with the distributing surfaces. Preferably, however, each of the cylinders 5 will
be provided with one or more lifting plates 37. In the machine shown, there
are two of these lifting plates 37 on each side of each form carrying cylinder,
although the machine might be constructed with a single plate on one side of

page_text: cach cylinder. The construction shown is deemed the preferable one, however,
and the number of plates will usually depend upon the length of the form surface
on the form-carrying cylinder. The plates 37 are preferably provided with guid-
ing blocks 38, which engage guides 39 formed on the cylinder, and are secured
to the cylinder by means of bolts 40, said bolts working in slots 41 formed in
the said plates. The lifting plates are curved to correspond to the curvature of
the cylinder, and in order to allow them to have the radial movement necessary
to effect their function, and at the same time provide a continuous track, they
are cut away as shown at 42, the cut-away portions of the plates overlapping
each other.
While the lifting plates may directly engage the shafts of the form-rollers,
each of the said rollers is preferably provided with a pair of trucks 43, which
are located so as to be engaged by the lifting plates 37, when they are in their
outward position.
The combined length of the plates 37 is equal to the length of the form
surfaces. When, therefore, the lifting plates are in their outer position, as the
form surface comes, in the revolution of the form-carrying cylinder, around to
the form-inking rolls, the trucks 43 of the rolls will be engaged by the plates,
and the rolls will be lifted and held out of contact with the form, until the form
has passed the rolls. After the form has pass the rolls, they will drop into their
proper position in the slotted bearings of the plate 36, and will contact with
the distributing surface 35.
Each
Various means may be provided for actuating the lifting plates. In the
machine shown, each of said plates is provided with a looped extension 44.
looped extension 44 is engaged by a cam 45, there being a pair of these cams
for each oppositely-located pair of plates. The cams 45 are carried on a shaft 46,
which is mounted in suitable bearings in the form-carrying cylinders, and the
shafts 46 of each form-carrying cylinder are preferably connected by means of a
connecting rod 47, which engages arms 48 carried on the shafts. When, there-
fore, one of the shafts 46 is rocked, its companion shaft will also be rocked, and
both sets of lifting plates actuated.
Any suitable means may be provided for rocking one of the pair of shafts. In
the machine shown one of the shafts is provided with a squared head 49, upon
which a wrench may be placed, to rock the shaft.
The printed sheets may be fed to and delivered from the machine in any
suitable manner. In the machine shown, there is provided a feed-board 50
mounted on the extension 1' of the frame, from which the sheets are fed and the
sheets are delivered by delivery cylinder 51, also mounted on the said extension,
the cylinder being provided with a gear 52, which meshes with the gear 18 before
described.
The operation of the construction which has just been described is as follows:-
When it is desired to operate the machine for the purpose of inking up, the
impression cylinder is brought to the proper position, with its impression surface
away from the form. A wrench is then placed on the squared head 31, and the
shaft 20 is rocked, so as to disconnect the arm 21 from the gear 18, and cause
the arm 23 to engage the notched block 24. By means of a wrench, one of each
pair of shafts 46 of the two form cylinders 5 is then rocked, to raise the lifting
plates into position, so as to be struck by the trucks 43 on the form-inking rollers.
The machine is now started, and the gear 18 will be revolved from the train
of gearing between it and the power shaft, and will, in turn, operate the gears 17
and 19, and rotate the form-carrying cylinders. As the form-carrying cylinders
rotate, the form rollers will be lifted away from the forms, but will run in con-
tact with the distributing surfaces, and thus cause the ink to become thoroughly
mixed and distributed on the rollers and the distributing surfaces. When the
machine has been operated for a sufficient length of time to get the ink into
proper condition, the machine will be stopped, the shaft 20 will be rocked, so as
to release the arm 23 from the notched block, and cause the arm 21 to engage the

page_text: notch 22 in the gear. This movement locks the gear and the impression cylinder
together. The shafts 46 will now be operated to depress the lifting plates, and
the machine is ready for printing.
The improvements so far described are particularly adapted for use in multi-
color machines of the type illustrated in the accompanying drawings, and
described in the fore-going specification, as no movement of the impression
cylinder is required. The invention, however, is not to be confined to use in
connection with this particular type of machine, as it is of general utility, and
may be used with many other forms of printing machines.
Referring to the construction shown in Figures 7 to 9, inclusive, which illus-
trate more particularly the mechanism for moving the vibrators, the frame 1 is
provided with any usual form of journal bearings, in which the shaft 4 carrying
the printing cylinder 5 is journaled, this cylinder being provided with a form
surface 34 and ink distributing surface 35. The printing cylinder carries a
gear 66, which meshes with a pinion 67, this pinion being mounted on a short
shaft 68, suitably journaled in the frame. The short shaft 68 is provided with
another pinion 69, which meshes with a pinion 70 on a power shaft, which is
suitably driven from any convenient source of power. The gearing just described
forms a convenient means by which the printing cylinder of this modification is
driven. It may, however, be driven by any convenient means, as, for instance,
that shown in connection with the preceding modification. The inking mechan-
ism may, in the main, be of any approved type. In the form selected to illustrate
the invention, it consists of a fountain F, from which the ink is transferred by a
ductor roll 72 to a distributing cylinder 73. The distributing cylinder 73 has
preferably the usual distributing rollers 74, running in contact therewith, which
assist in breaking up and mixing the ink.
The ink may be transferred from the surface of the distributing cylinder to
the form-rollers in any suitable manner. In the machine shown, there are pro-
vided transferring rollers 75 and 76, which are mounted in suitable brackets,
and which run in contact with the distributing roller, and with the vibrators 77
and 78. The vibrators 77 and 78 run in contact with form rollers 79, any suit-
able number of these rollers being provided.
The inking mechanism is preferably provided with certain other vibrators,
there being as many of these vibrators as is deemed necessary or desirable. In
the machine shown, there are two such additional vibrators, which are lettered 81,
and 83, the rolls 80 and 82 being the ordinary rider rolls. The several vibrators
are so mounted that their vibrating movement is intermitted at the time when
the form-rollers with which they are in contact are running over the form, but
they continue their vibrating movement when the form rollers with which they
cooperate are not in contact with the form.
Various mechanisms may be employed by which the vibrators are given the
movement described. In the machine shown, the shaft of each of the vibrators
is provided with a collar, which is engaged by a cam-actuated lever, the said
lever operating to give the vibrator its vibrating movement. These levers may
be variously positioned, and the cams which operate them, operated in any con-
venient way.
In the machine shown, the shaft 77' of the vibrator 77 is provided
with a collar S4. This collar is engaged by a pin 85 on a rocking lever 86, which
extends from a hub 87. The hub 87 is mounted on a shaft 88, which is supported
in bearings 89 suitably secured in the frame of the machine. The hub 87 has,
extending therefrom, an arm 90, carrying a pin 91, which engages a cam
groove 92, formed in a cam block 93, which is mounted on and rotates with the
shaft 4 of the printing cylinder. It will be understood that the cam 93 is the

means by which the vibrator is given its lengthwise movement.
however, so formed and timed, that during the time when the rolls 79 with which
the vibrators cooperate are in contact with the form surface. there will be no
movement of the vibrator in a lengthwise direction. When, however, the form

page_text: surface has passed out from under the form rollers 79, the cam will cause the
vibrator to resume its lengthwise reciprocating movement, and will continue it
until the form surface again comes in contact with the form rollers. The cam 93
is preferably so formed that the vibrator will be given one complete reciprocation
for each revolution of the form-carrying cylinder. The form of the cam may,
however, be varied, if desired, so as to give less or more than a complete recip-
rocation or the vibrator.
The shaft 88 preferably has secured thereon an arm 94 having a pin 95 which
engages a cam groove 96 in a cam block 97, which is secured on the shaft 4,
alongside the cam block 93. The shaft 88 also preferably has secured to it an
arm 99 having a pin 100, which engages a groove in a collar 101, mounted on
the shaft 83 of the vibrator 83. The cam 97 is constructed and timed in the
same manner as the cam 93, and operates to give the vibrator 83 a movement
similar to that of the vibrator 77, that is to say, when the form rollers 79 with
which the vibrator 83 cooperates are in contact with the form, there is no longi-
tudinal movement given to the vibrator. When, however, these rollers pass off
the form, the vibrator is operated by the cam, and is preferably given one com-
plete reciprocation for each rotation of the form-carrying cylinder.
The arrangement for moving the vibrators 78 and 81 is the counterpart of
that used for the vibrators 77 and 83. A shaft 102 is mounted in bearings 103,
extending from the frame of the machine. On this shaft is mounted a lever 104,
which is similar to the lever 86, and which has an extension 105, which carries
a pin 106 engaging the cam groove 107 in a cam block 108 mounted on the
shaft 4. The lever 104 is provided with a pin 109, which engages a collar 110 on
the shaft 78' of the vibrator 78. The shaft 102 has also mounted on it a lever 111,
provided with a pin 112, which engages a collar 113 on the shaft 811 of the
vibrator 81. The shaft is rocked by an arm 114 having a pin 115, which engages
a cam groove 116 in a cam block 117, also carried on the shaft 4.
The form rollers and vibrators may, if desired, be given their rotary move-
ment by contact with the form and distributing surfaces. Preferably, however,
the shaft of the form cylinder is provided with a gear which engages with
gears 121 on the shafts of the form-rollers, and these gears 121 engage with
similar gears 122 on the shaft of the vibrators. It will be understood, of course,
that the gears 122 have a face sufficiently wide to permit the longitudinal move-
ment of the vibrators, without disengaging them from the gears on the form
rollers.
The invention is not, furthermore, to be limited to the particular mechanisms
which have been described for carrying it into effect. Many changes may be
made in the mechanisms by which the several operations are performed, and
such changes will readily suggest themselves to skilled mechanics. The invention
is not, therefore, to be confined to the specific mechanical details which have been
shown and described.

located along the form surface, substantially as described.
24. In a printing machine, the combination with a form cylinder, having an
ink-distributing surface, of a set of form-rollars, mounted in stationary bearings,
trucks on the rollers, a set of radially moving overlapping lifting plates located
along the form surface, and a set of connected cams for operating the lifting
plates, whereby the plates are operated simultaneously, substantially as described.
25. In a printing machine, the combination with an impression cylinder, and a
shaft with which it is rigidly connected, of a continuously running gear loosely
mounted on the shaft, means for connecting the cylinder to and disconnecting it
from the gear, a plurality of form cylinders having operating gears meshing with
the continuously running gear, a set of form-rollers, stationary bearings in which
they are mounted, ink-distributing surfaces on the form cylinders, with which
the form-rollers contact, and means for lifting the form rollers in their bearings,
to cause them to clear the form as the cylinders rotate, substantially described.
26. In an inking apparatus, the combination with a form, of a roller mounted
to have rotary movement, and means for giving it an intermittent reciprocating
movement in the direction of its axis, without varying its distance from the
form, substantially as described.
27. In an inking apparatus, the combination with a form, of a group of inking
rollers mounted to have a rotary movement, and means for giving one or more
of the rollers a lengthwise reciprocation when the rollers are not in contact with
the form, the reciprocation being intermitted as the form passes under the rollers,
substantially as described.
28. In an inking apparatus, the combination with a group of form-inking
rollers, of a vibrator cooperating therewith, and means whereby the vibrator is
given an intermittent lengthwise reciprocation with respect to the form-rollers,
substantially as described.
29. The combination with a form, of a group of form-rollers, a series of vibrators
cooperating with the form-rollers, means for giving each of the vibrators an inter-
mittent lengthwise reciprocation with respect to the form-rollers, said movement
being intermitted while the rollers with which the vibrators cooperate are in con-
tact with the form, substantially as described.
30. The combination with a form, of a series of inking rollers cooperating there-
with, means for giving one of the rollers intermittent lengthwise reciprocations,
while the rollers are out of contact with the form, said means consisting of a cam
moving with the form and suitable connections, the cam being so formed as to
cause a dwell in the lengthwise movement of the roller, as the form is passing
beneath the inking-rollers, substantially as described.
31. The combination with a rotating form-carrier and its form, of a group of

page_text: inking rollers cooperating therewith, a cam mounted on and rotating with the
form carrier, and suitable connections between the cam and one of the rollers,
whereby it is given an intermittent movement in the direction of its axis, while it
is out of contact with the form, the cam being formed to cause a dwell in the
movement of the roller, as the form is passing beneath the inking rollers, sub-
stantially as described.
32. The combination with a form carrier, of a group of form-inking rollers, a
series of vibrators cooperating with the form-rollers, a series of levers connected
to the vibrators, and a series of cams for operating the levers, said cams being
formed to intermit the movement of the vibrators while the forms are in contact
with the rollers with which the vibrators cooperate, substantially as described.
33. The combination with a rotating form-carrier, of a group of inking rolls,
including suitable vibrators cooperating therewith, a shaft located at one end of
the carrier, cams on the shaft of the carrier, a lever journalled on the first-
named shaft, and engaging one of the vibrators at one end, and one of the cams
at its other end, a lever connected to the first-named shaft, and engaging one of
the vibrators, and means whereby one of the cams is caused to rock the shaft and
move the vibrator while the inking rolls are out of contact with the forms, sub-
stantially as described.
34. The means substantially as herein shewn and described, whereby the impres-
sion cylinder of a printing machine, having one or more cooperating form cylin-
ders, is held stationary with respect to the form-cylinders, while they are revolved.
35. The means, substantially as herein shewn and described, for controlling the
position of the inking rollers, so as to allow them to run in contact with the ink-
distributing surfaces of a form-cylinder, but to be lifted out of contact with the
form surface.
36. The means substantially as herein shewn and described, of giving an inter-
mittent reciprocating movement to the vibrators, said movement being inter-
mitted when the form rollers with which the vibrators cooperate are passing over
the form.
