Improvements in Inking Mechanism for Printing Machines.
We, EDWARD THOMAS CLEATHERO, of 16 Tollington Place, London, N.
Engineer, and EDMUND WILLIAM HORNSEY WALKER, of 31 Bouverie Street,
London in the County of Middlesex, Engineer, do hereby declare the nature of
this invention to be as follows:-
This invention relates to improvements in connection with inking mechanism for
printing machines, the object of the invention being to produce an even distribution
of the ink upon the inking rollers, and to provide for adjustment of such rollers in
a simple and efficient manner.
In carrying our invention into effect we mount a bracket upon each of the side
frames of the printing machine, and shape the bracket so that it may preferably
obtain support also from the standard or bracket of the cylinder spindle bearing.
Upon the upper ends of the bracket we mount an ink duet or reservoir, and we
arrange the roller or ink receiver to revolve within bearings carried upon the
brackets, and collect the ink from the ink duet. We give motion to this main
ink collecting roller preferably by means of chain driving gear driven from a
counter shaft which we employ for giving a transverse motion to the inking
cylinders.
Upon the spindle of the inking roller we mount a peculiarly formed set of cam
plates, the cam plates being arranged so that when placed side by side the circum-
ferential edges of the plates can be moved to cause a short or a lengthened path to
be given for the cam surface, the plates being held together by suitable connecting
bolts and slots for enabling the desired alteration in position to secure the extended
bearing to be made. We mount a rocking bell crank lever beneath the ink
collecting roller and we cause one end of the bell crank to carry a tumbler or roller
for bearing against the cam surfaces of the plates before described, and the other
end to have carried upon it an inking roller spindle so that when the tumbler is
pressing against the revolving cam plates, cam paths cause the roller to be raised
and to fall, thus giving the ink conveying roller a rocking motion that it may bear
first on the ink collecting roller and then convey it to the inking cylinder.
We
We mount upon our brackets a number of guiding rollers for distributing the
ink upon the inking cylinder, and we give to the inking cylinder a lateral movement
by means of a rocking or vibrating lever connected with a link actuated from an
eccentric having an adjustable throw which we drive from our counter-shaft.
mount ink rollers within our bracket frames and make them to be adjustable by
means of suspending links having slotted bearing holes provided within them, and
we arrange a second distributing cylinder within our side frames and give to this a
vibrating movement opposite to that produced upon our upper inking cylinder by
causing a bell crank lever attached to our eccentric link to move backwards and
forwards a double ended fork which embraces at its ends onc and the other of the
two inking rollers. We mount the double fork boss upon a spindle carried within
eyes or bosses formed upon our bracket or side frame, and we provide a projecting
bell crank attachment for enabling the desired rocking movement to be obtained
from the reciprocating link driven from the adjustable eccentric.
We provide further connecting rollers to convey the ink from the bottom
distributing cylinder to the ink rollers mounted upon the lower end of our
combination arrangement, these connecting rollers being carried with links

page_text: which are of an adjustable character, and arranged so that they may be made to
make contact with two inking rollers and with the vibrating distributing cylinder
at the same time.
We mount our inking rollers in series upon saddle frames provided with
adjustable set screws and guide pins for enabling the rollers to be raised vertically
and to be moved horizontally by the adjusting screws, and we determine the position
of the rollers to suit the type form which is to pass beneath them.
We do not limit the application of our improved system of distributing ink to
the inking rollers to any particular method of giving motion to the rollers, or to
any special arrangement of framework for carrying them, and we modify the
method of mounting them together with the gearing for driving them to suit any
particular requirement, or to suit the special form of machine to which they are to
be applied.

Improvements in inking Mechanism for Printing Machines.
We, EDWARD THOMAS CLEATHERO, of 16 Tollington Place, London, N.
Engineer, and EDMUND WILLIAM HORNSEY WALKER, of 31 Bouverie Street
London in the County of Middlesex, Engineer 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 improvements in connection with inking mechanism for
printing machines, the object of the invention being to produce an even distribution
of the ink upon the inking rollers, and to provide for adjustment of such roller in
simple and efficient manner.
In the accompanying drawing. Figure 1 and 2 are front and end elevations
repertively of a printing machine fitted with our invent:
larged detail view-errequling thereto.

In enrrying our invention into effect we mount a bracket A unun each of the Mo
tremes 13 of the printing machine, and shape the bracket so that it may preferably
obtain support also from the standard or bracket C of the cylinder pindle
pon the upper ends of the bracket A we mount an ink duct or reservoir D, and
we arrange the roller or ink receiver E to revolve within bearings carried upon the
bruchet A and collect the ink from the ink duct. We give motion to this main ink
collecting roller E preferably by means of chain driving gear F driven from a
counter shaft G which we also employ for giving a transverse reciprocating motion
to the inking cylinders S. Y.
Upon the spindle of the inking roller we mount the well known divided set of
cam plates, H, H1, H2, the cam plates being arranged so that when placed side
by side, the circumferential edges of the plates can be moved to cause a short or a
lengthened path to be given for the cam surface, the plates being held together by
suitable connecting bolts and slots for enabling the desired alteration in positiu
to secure the extended bearing to be made. We mount a roulding bell crank lever K
inneath the ink collecting roller E and we reuse one end of the hell crank to errry
a tumbler or roller, sufficiently wide to Fear in the of th
le price of plate.

ou the ink collecting roller E and then upon the inking or distributing cylinder Y
and so deposit ink thereupon.
We mount upon our brackets a number of rider rollers O for distributing the ink
upon the inking or distributing cylinder Y and we give to the said inking
cylinder Ya lateral movement by means of a rocking or vibrating lever TT
connected to a link P1 actuated from an eccentric P2 having an adjustable
throw, which we drive from our counter-shaft G actuated from the main
shaft G2 by means of the transversely disposed shaft G 1. We mount ink on
conveying roller R within our bracket frames A and make it to be adjustable by
means of a suspending link 1 having a slotted bearing hole provided therein;
and we arrange a second inking or distributing cylinder S within our side frames
and give to this a vibrating movement opposite to that produced upon our upper
inking or distributing cylinder Y by causing a bell crank lever T attached to our
eccentric link P1 to move backwards and forwards a double ended fork T 1 which
embraces at its ends one and the other of the two inking rollers Y and S.
We mount
the double fork boss upon a spindle U carried within eyes or bosses formed upon
our bracket or side frame A and we provide a projecting bell crank attachment T
for enabling the desired rocking movement to be obtained from the reciprocating
link P1 driven from the adjustable eccentric P 2.
We provide rider rollers ss upon the second distributing cylinder S to assert
the uniform distributing of ink thereon.
We provide further connecting or conveying rollers W WI to convey the ink
from the bottom distributing cylinder S to the ink rollers Z, Z1, Z2, Z3, mounted
upon the lower end of our combination arrangement, these connecting rollers being
carried within links W W 1 which are adjustable in slots formed therein and
arranged so that they may be made to make contact with two inking rollers
as Z Z1 or Z2 Z3 and with the vibrating distributing cylinder S at the
same time.
We mount our inking rollers in series upon saddle frames X X 1 X 2 provided
with adjustable set screws 1 and guide pins xy for enabling the rollers to be
raised vertically and to be moved horizontally by the adjusting screws, and we
determine the position of the inking rollers Z ZI Z2 Z3 to suit the type form
which is to pass beneath them.
We give motion to each of the distributing cylinders Y. S. from the impression
cylinder by means of a pinion R'; and we communicate motion from the
distributing cylinder S to the rollers W W 1 by gearing. The distributing
cylinders we preferably make of steel and the conveying inking and rider rollers
of composition.
We do not limit the application of our improved system of distributing ink to the
inking rollers to any particular method of giving motion to the rollers, or to any
special arrangement of framework for carrying them, and we modify the method of
mounting them together with the gearing for driving them to suit any particular
requirement, or to suit the special form of machine to which they are to be
applied.
Having now particularly described and ascertained the nature of our said inven-
tion and in what manner the same is to be performed, we declare that what we
claim is
1. In inking mechanism for cylinder and similar printing machines the arrange-
ment of rollers and means of actuation substantially as hereinbefore described and
as illustrated in the accompanying drawings.
2. In inking mechanism for cylinder and similar printing machines, an inking or
distributing roller of comparatively large diameter and capable of rotation by
gearing, superposed above the series of type inking rollers; such as inking
or distributing roller receiving ink from the duct roller intermittently and
conveying the ink deposited thereon to conveying rollers in gear therewith, each

page_text: of which or each of the lower series of which conveying rollers rotates in contact
with two of the type inking rollers thereby effecting the rotation thereof and the
uniform distribution of ink thereon.
3. In inking mechanism for cylinder or similar printing machines, in combination
a distributing roller of steel or other similar metal or material in gear from the
impression cylinder of the machine and superposed above the type inking rollers, a
