Improvements in Inking Apparatus for Printing Presses.
I, JOSEPH YARDLEY JOHNSTON, of 22, Bride Lane, in the City of London,
Manufacturer of Steel Die and Plate Presses, do hereby declare the nature of
this invention to be as follows:-
This invention has reference to printing press inking apparatus of the kind
in which an ink reservoir is supported adjustably by an elastic or spring support,
and is furnished with an ink agitator and with rollers, the arrangement being
such that the reservoir and rollers can be by suitable means depressed, to allow
an edge or edges of a die or surface to be inked, to pass the ink roller without
making contact with it, and that after the said edge has passed, the reservoir and
rollers will be in an automatic manner raised so as to bring the inking roller
into and keep it in contact with the die or surface to be inked, so as to ensure
effectual inking as movement takes place of the surface to be inked and the
inking roller in relation to one another.
Inking apparatus of the kind referred to is described and claimed in the
Specification of former Letters Patent granted to me No. 14664/94, in which
specification there is also described a printing press in which improved inking
apparatus according to my present invention may be advantageously employed,
but it is to be understood that my present invention is applicable also in printing
presses otherwise constructed.
In an inking apparatus according to my present invention, the ink reservoir
and its elastic or spring support are so constructed and arranged, that without
unscrewing and removal of the nuts, or readjustment, the reservoir with its
contained parts can be removed and replaced or one reservoir can be removed
and another substituted, as, for example, if it be desired to use a different
colour of ink.
For this purpose, the reservoir is carried by a table or support from which
the reservoir can be readily lifted, and which table or support is itself carried
in such wise that if depressed and released, it will be automatically returned to
the highest position it is for the time being adjusted to assume.
In one arrangement, the said table or support rests on springs which surround
tubes that work through guiding holes in a suitable frame, and are at or near
their lower ends connected with a crosshead or plate provided with an adjusting
screw, whereby the height of the table or support of the ink reservoir and rollers
can be adjusted according to requirement. Other adjusting means may be
employed. In the arrangement just described, the under side of the ink reservoir
is furnished with projecting pins or rods that fit into the upper ends of the
tubes, so as to retain the reservoir in its proper position upon the table or
support. Other means may obviously be employed to this end. Instead of the
tubes above referred to, pins or rods projecting from the lower side of the table
or support may work in grooves or guides in the frame between which and the
table or support, springs are interposed, an adjusting screw or equivalent being

page_text: provided, whereby the distance of the table or support from the frame or part
that carries the springs can be adjusted according to requirement.
In some cases, a weighted lever or levers or a pneumatic arrangement may
be substituted for the springs.
With such an arrangement as either of those above indicated, it is possible
where desired, to so adjust the parts, that, in the highest position of the table
or support, the inking roller will clear the die or printing surface in the machine
to which it is applied.
When applying inking apparatus for inking dies that are carried round in a
manner such as obtains in the kind of press referred to in my previous specifica-
iion above mentioned, it is necessary to adjust the position of the inking roller
to suit the width of the die or surface to be inked, so as to ensure that the front
edge of said die or surface shall clear the inking roller.
For this purpose, according to my present invention, the frame that carries
the adjustable table or support for the ink reservoir is made movable about a
horizontal axis located at or near its lower end and is provided with adjusting
means.
One convenient construction and arrangement of inking apparatus according
to my invention is as follows:-
An upright frame is pivoted at its lower end on screw centres having their axes
in a common horizontal line and which are carried in lugs on a bracket secured
to a cross tic or otherwise. The screw centres are furnished with lock nuts,
and are of sufficient length to serve for accurately adjusting the position of the
frame in a direction parallel to the inking roller axis; to admit of other adjust-
ments the bolt or screw holes in the bracket are of elongated form. In the
upper part of the frame are two parallel holes, in which tubes slide.
The upper
ends of these tubes are screwed, or otherwise securely fixed in the ink reservoir
table or support; their lower ends pass through holes in a plate and are secured
therein by lock nuts. The upper ends of the tubes are surrounded by strong
helical springs which abut against the top of the frame and the underside of
the table and support the said tubes and table. In the plate there is a screw
provided with a milled head; this screw abuts against a part of the frame and
serves to adjust the height to which the springs can raise the tubes and table.
A pinching screw is provided for locking the adjusting screw.
The pivoted frame is furnished with lugs that carry adjustable screw centres
which so support a nut that it can swivel.
Through this nut there passes a practically horizontal screw journalled at its
outer end in a bracket fixed to the frame of the press. It is provided with a
hand wheel, and with means for preventing end motion and taking up wear;
also with collars to prevent its being drawn out of the nut and to limit the extent
of its motion. By rotating the screw the position of the top of the pivoted
frame and consequently of the ink reservoir and its rollers can be adjusted as
required. A pinching screw is or may be provided for locking the adjusting
screw when adjusted.
The reservoir for printing matter, such as ink or colour, is an open topped
vessel conveniently it may be rectangular in plan the bottom being curved to a
circular are.
The bottom is so formed externally as to rest securely upon the
table or support carried by the pivoted frame; and is provided with a couple of
parallel pins or studs adapted to enter the tubes with a good fit. The ends of
these pins or studs are preferably tapered so that they will the more readily
enter the tubes.
The rollers and agitator are worked through a short spindle which is supported
in a bearing formed in the outer end of the ink reservoir and which is lined
with a hardened steel bush (readily renewable when worn). On the outer end
of the spindle there is fixed a sprocket wheel. At the inner end of the spindle
is an eccentric preferably formed in one piece with it. Suspended in the interior
of the reservoir by screw studs is an agitator, it has one or more parallel horizontal

page_text: bars provided with teeth inclined in opposite directions, to effectually stir the
ink, and produce cross-currents therein. The agitator is provided with parallel
faces and is oscillated by the eccentric as it rotates between them.
At the inner end of the reservoir and in the same axial line as the short
spindle already described there is a screw centre provided with a lock nut, and
forming the support for one end of the spindle of the main ink roller.
This spindle is at its other end furnished with a flange which fits into a
central recess in the eccentric and a semi-circular notch in the said flange fits
over a stud so that the spindle is driven by and practically forms a continuation
of the short spindle previously mentioned.
The main ink roller is secured on its spindle by set screws, or in any other
convenient manner.
In practice the reservoir is filled with ink to such a height that the main
roller is about half submerged therein, and as it rotates it takes up an ample
supply of ink on its surface. The roller which inks the die and which I call
the inking roller is placed at the centre of the top of the main roller and parallel
to it, receives the ink from the main roller, and is driven by frictional contact
therewith. In practice the inking roller advantageously comprises a spindle
surrounded by a wooden body covered with plush or other suitable material.
The wooden body is convenient for the attachment of the plush or other material,
but metal may be employed in place of wood, if preferred. For some purposes,
the roller may consist of ordinary inking roller or other suitable composition,
cast around the spindle in the usual way. The spindle ends rotate in holes
formed eccentrically in plugs which are inserted in openings in the ends of the
reservoir. This arrangement affords a ready means of adusting the distance
of the inking roller from the main roller, according as more or less ink is required
on the die, and enables the inking roller to adapt itself to irregularities in the
surface to be inked and in cases where one end of the die surface requires
more ink than the other, it affords facilities for adjusting the ends of the rolleı,
independently of each other.
The plugs are or may be provided with polygonal heads, for convenience in
rotating them and there are means such as pinching screws to fix them in position
when adjusted.
A regulating roller is provided supported in eccentric adjustable plugs in a
similar manner, to regulate the amount of ink carried by the main roller to
the inking roller. The regulating roller may be of metal but in some cases
especially when using deeply sunk dies I employ a roller covered with flexible
or brush-like material such as plush for example.
In the case of the rollers intended to be capable of adjustment at either of
their ends the spindles carrying such rollers are formed at their ends with parts
resembling parts of spheres.
The top of the reservoir is provided with covers suitably hinged at or near
their edges, one to each side of the inking roller to arrest dust and dirt and
check evaporation of ink. To enable the inking roller and other parts including
the reservoir to be depressed by a suitable appliance in order that the edge of a
die or surface to be inked may clear the inking roller, there is provided at or
near each end of the spindle of that roller a disc or roller free to rotate on the
spindle and of slightly larger diameter than the inking roller; these discs or
rollers are intended to bear against any suitable contrivance with which the
press is provided for effecting the required temporary depression of the inking
roller and other parts.
To remove the ink rollers from the reservoir, the outer eccentric plug of the
inking roller is drawn partly out, whereupon the end of its spindle can be lifted
up through a gap provided for the purpose and the roller then taken out.
The ink regulating roller is removed in a similar manner by drawing back
one of its eccentric plugs. The screw centre of the main roller spindle being
then screwed back a short distance, the main ink roller with its spindle can be

page_text: lifted out. The ink agitator is removed by drawing back the studs on which it
swings.
Thus the whole of the interior mechanism of the ink reservoir can be quickly
taken apart when required for cleaning or other purpose.
The use of the adjusting screw connected to the pivoted frame is to adjust
the ink reservoir for different widths of dies, so that the inking roller is always
delivered on the die or printing surface parallel to its front edge, and the inking
part of the said roller is of sufficient length to ink the largest die or printing
surface the machine is designed to take.
The reservoir table adjusting screw serves to adjust the position of the inking
roller to suit dies or equivalents of varying thickness, as well as to regulate the
amount of force with which the springs shall press the inking roller against the
die or printing surface; that screw is also used when it is desired to pull the
ink reservoir down clear of the die or printing surface, so that the latter can
pass over the inking roller without being inked.
When apparatus according to this invention is used in a press furnished with
suitable depressing mechanism for enabling the front edge of a die or equivalent
to clear the inking roller, the said screws in combination with the adjustable
eccentric bearings of the inking roller and the depressing devices, afford con-
venient means for controlling with accuracy all the various requirements to be
observed in charging the die or printing surface with the necessary ink, colour
or other matter.
As already indicated, the ink reservoir can be removed by simply lifting it
off, without disturbing or affecting the adjustments and it can be replaced or
another reservoir be substituted for it with the certainty of exactly occupying
the previous position, as the parallel pins which fit into the tubes accurately
locate and secure the reservoir in place.
When inking apparatus such as described is applied in a press of the type
described in my previous patent already referred to, the sprocket wheel driving
the main roller and ink agitator can be conveniently driven as follows:-
A standard is fixed to the main frame of the press terminating at its upper end
in a long tubular socket within which a stud or pin is adapted to slide vertically
being supported on a spring and prevented from twisting by a horizontal pin
passed through a slot in its lower end.
Fixed to the top of the said pin is a device having two spindles journalled in
it at right angles to each other. On the outer end of one of these spindles is a
sprocket wheel driven by a chain from another sprocket wheel which latter is
fixed on the hub of the belt pulley of the press. The inner end of the said
spindle is provided with a bevel pinion which drives a bevel wheel on the inner
end of the second spindle. The outer end of the second spindle has a sprocket
wheel running loose thereon, which drives the sprocket wheel on the ink reservoir
by a chain. The hub of the loose sprocket wheel is provided with clutch teeth
to engage with similar clutch teeth on a knob that can be slidden on a feather
on the spindle. A spring latch pin concealed within the said knob holds it
either in or out of engagement with the sprocket wheel. The inking roller
and agitator can therefore be instantly stopped by merely pulling the knob
out and started by pushing it in.
The gearing is supported on the spring in order that it may automatically
adapt its position to variations in the vertical adjustment of the ink reservoir
effected by the table adjusting screw and to the small downward motion of the
reservoir caused each time by the passage of the depressing devices over the dises
or rollers provided for said devices to act against. The object of driving the
inking apparatus from the belt pulley hub, is that when the said pulley is dis-
connected from the main shaft in order to bring the press to rest, the inking
annaratus shall still continue in motion, it being necessary with many kinds
of ink or colouring matter to keep the same in constant motion or agitation, to
prevent its drying on the rollers and to keep it thoroughly mixed and avoid the

page_text: sediment or solid particles settling to the bottom of the reservoir. At the same
time the motion can be stopped, if required, by the clutch knob, as before
described. Although I have thus set forth a convenient arrangement according
to my invention it is to be understood that the details are susceptible of variation.

Improvements in Inking Apparatus for Printing Presses.
I, JOSEPH YARDLEY JOHNSTON, of 22, Bride Lane, in the City of London,
Manufacturer of Steel Die and Plate Presses, 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 has reference to printing press inking apparatus of the kind
in which an ink reservoir is supported adjustably by an elastic or spring support,
and is furnished with an ink agitator and with rollers, the arrangement being
such that the reservoir and rollers can be by suitable means depressed, to allow
an edge or edges of a die or surface to be inked, to pass the ink roller without
making contact with it, and that after the said edge has passed, the reservoir and

Inking apparatus of the kind referred to is described and claimed in the
Specification of former Letters Patent granted to me No. 14664/94, in which
specification there also described a printing press in which improved inking
apparatus according to my present invention may be advantageously employed,
but it is to be understood that my present invention is applicable also in printing
presses otherwise constructed.
In an inking apparatus according to my present invention, the ink reservoir
and its elastic or spring support are so constructed and arranged, that without
unscrewing and removal of nuts, or readjustment, the reservoir with its
contained parts can be removed and replaced or one reservoir can be removed
and another substituted, as, for example, if it be desired to use a different
colour of ink.
For this purpose, the reservoir is carried by a table or support from which
the reservoir can be readily lifted, and which table or support is itself carried
in such wise that if depressed and released, it will be automatically returned to
the highest position it is for the time being adjusted to assume.
In one arrangement, the said table or support rests on springs which surround
tubes that work through guiding holes in a suitable frame, and are at or near
their lower ends connected with a crosshead or plate provided with an adjusting
screw, whereby the height of the table or support of the ink reservoir and roller
can be adjusted according to requirement. Other adjusting means may be
employed. In the arrangement just described, the underside of the ink reservoir
is furnished with projecting pins or rods that fit into the upper ends of the
tubes, so as to retain the reservoir in its proper position upon the table or
support. Other means may obviously be employed to this end. Instead of the

page_text: tubes above referred to, pins or rods projecting from the lower side of the table
or support may work in grooves or guides in the frame between which and the
table or support, springs are interposed, an adjusting screw or equivalent being
provided, whereby the distance of the table or support from the frame or part
that carries the springs can be adjusted according to requirement.
In some cases, a weighted lever or levers or a pneumatic arrangement may
be substituted for the springs.
With such an arrangement as either of these above indicated, it is possible
where desired, to so adjust the parts, that, in the highest position of the table
or support, the inking roller will clear the die or printing surface in the machine
to which it is applied.
When applying inking apparatus for inking dies that are carried round in a
manner such as obtained in the kind of press referred to in my previous specifica-
tion above mentioned, it is necessary to adjust the position of the inking roller
to suit the width of the die or surface to be inked, so as to ensure that the front
edge of said die or surface shall clear the inking roller.
For this purpose, according to my present invention, the frame that carries
the adjustable table or support for the ink reservoir is made movable about a
horizontal axis located at or near its lower end and is provided with adjusting
means.
Referring to the accompanying drawings,
Figs. 1 and 2 are respectively a rear elevation and a side elevation, both partly
in section, and
Fig. 3 is a sectional plan, through A-A Fig. 2, of a convenient construction
and arrangement of inking apparatus according to this invention.

is the reservoir with inking roller b, and c is a die, the surface of which is
to be inked. The die is carried by a die block mounted in a revolving arm
forming part of the press to which the inking apparatus is supposed to
be applied. is a table resting on springs e and to which tubes f are fixed:
the tubes work through parallel guiding holes in the standard or frame h
and are connected with a crosshead or plate i provided with screw jabutting
against the frame, whereby the height of the table can be adjusted according
to requirement. The springs e surround the tubes f and abut against the top
of the frame and the underside of the table d. Projecting from the underside
of the ink reservoir a are pins or rods which are formed with tapering ends
and fit into the upper portions of the tubes f, so as to retain the reservoir in its
proper position upon the table. By means of the screw j, when it is not desired
to ink the die c, the parts can be so adjusted, that, in the highest position of
the table d, the inking roller b will be clear of the die e so that the latter can pass
over it without being inked. The screw j also serves to adjust the position of
the inking roller to suit dies of varying thickness, as well as to regulate the
force with which the springs e shall press the inking roller against the die.
The frame his pivoted at its lower end on screw centres which are carried in
Jugs on a bracket m secured to a part of the press frame. The screw centres are
furnished with lock nuts, and are of sufficient length to serve for accurately
adjusting the position of the frame in a direction parallel to the inking roller
axis to admit of other adjustments the bolt or screw holes in the bracket m
are of elongated form. o are lugs on the frame h that carry adjustable screw
centres which so support a nut 7 that it can swivel. Through this nut there
passes a. screw r. the outer end of which passes through a bracket s
fixed to the frame of the press. It is provided with a hand
wheel t, and with means for preventing end motion and taking up wear; also
with collars u to prevent its being drawn out of the nut q and to limit the extent
of its motion. By rotating the screw the position of the top of the pivoted
frame and consequently of the ink reservoir and the inking roller can be

page_text: adjusted as required. is a pinching screw for locking the adjusting screw j;
the screw may also be locked by similar means.
The ink reservoir a may be rectangular in plan and have its bottom curved
to a circular are internally but so formed externally as to rest securely upon
the table d. w is a roller which dips into and conveys the ink contained in
the reservoir to the inking roller which is in contact with and is driven by the
roller which is secured on its spindle by set screws. is a roller bearing
against the roller and serving to evenly distribute and regulate the amount
of ink conveyed to the roller b. Suspended in the reservoir by screw studs 1 is
an agitator comprising bars 2 provided with teeth inclined in opposite directions,
to enectually stir the ink, and produce cross-currents therein.
The rollers and agitator are worked through a short spindle 3 which is sup-
ported in a bearing 4 lined with a hardened steel bush that can be readily
renewed, when worn. Un the spindle 3 is fixed a sprocket wheel 5 which is
preferably geared to the main pulley of the press; "at the inner end of the
spindle 3 is an eccentric 6 preferably formed in one piece with it and rotating
between parallel faces 7 formed on the agitator, thus causing the said agitator
to oscillate. The eccentric is formed with an axial recess adapted to receive a
Hange on the one end of the spindle of the roller w the other end of which is "
supported by a screw centre 10 provided with a lock nut 11. The flange 9 is
formed with a semi-circular notch 12 which fits over a stud 13 that projects into
said recess from the eccentric so that the spindle is driven by and practically
forms a continuation of the spindle 3.
In practice, the inking roller b advantageously comprises a spindle surrounded
by a wooden body covered with plush or other suitable material, but metal
may be employed in place of wood, and for some purposes, the roller may
consist of ordinary inking roller composition, cast around the spindle in the
usual way. The ends of the spindle of the roller b rotate in holes formed
eccentrically in plugs which are inserted in openings in the ends of the
reservoir and by turning which the distance of the inking roller as a whole from
the main roller may be regulated, according as more or less ink is required on
the die; the ends of the roller may be similarly adjusted independently, in
cases where one end of the die surface requires more ink than the other or where
the die presents an uneven surface. The plugs are fixed in the required attitudes
by set screws. The roller, which is supported in eccentric adjustable plugs *
in a similar manner, may be of metal but, in some cases, especially when using
deeply sunk dies, I employ a roller covered with flexible or brush like material,
such as plush for example.
The rollers and r, in order that their ends may be adjusted independently
without detriment to their freedom of rotation, have their spindles formed with
partly spherical end portions 17 as shown.
The reservoir a is provided with hinged covers 14 arranged one each side of
the inking roller b to arrest dust and dirt and check evaporation of ink. Near
each end of the spindle of the roller b is a disc or roller 15 free to rotate on the
spindle and of slightly larger diameter than the roller; these discs or rollers are
intended to bear against any suitable contrivance with which the press is pro-
vided for effecting the required temporary depression of the inking roller
necessary to prevent the inking of the die edge by contact with the die.
The inking roller b can be removed after partly drawing out its outer eccentric
plug, the end of the spindle being lifted through a gap 16 provided for the
purpose in the reservoir end. The roller can be removed after one of its
eccentric plugs has been drawn back. The screw centre 10 being then screwed
back, the roller w with its spindle can be lifted out. The ink agitator is freed
for removal by drawing back the studs.1, 1. Thus the whole of the interior
mechanism of the ink reservoir can be quickly taken apart when required for
cleaning or other purpose.
When apparatus according to this invention is used in a press furnished with

page_text: suitable depressing mechanism for enabling the front edge of a die to clear the
inking roller, the screws j and r in combination with the adjustable eccentric
bearings of the inking roller and the depressing devices, afford convenient means
for meeting with accuracy all the various requirements in charging the die with
the necessary ink.
17
As already indicated the ink reservoir a can be removed by simply lifting it
off, without disturbing or effecting the adjustments and it can be replaced or
another reservoir be substituted for it with the certainty of exactly occupying
the previous position, as the parallel pins which fit into the tubes
locate and secure the reservoir a in place.
accurately
When inking apparatus such as described is applied in a press of the type
described in my previous patent already referred to, the sprocket wheel 5 can be
conveniently driven by means of gearing arranged as shown in Fig. 6, wherein 15
is a standard fixed to the main frame of the press and terminating at its upper
end in a long tubular socket within which a stud or pin 16 is adapted to slide
vertically being supported on a spring 17 and prevented from twisting by a
horizontal pin 17" passed through a slot in its lower end. Fixed to the top of
the said pin is a bracket having two spindles 18, 19 journalled in it at right angles
to each other. On the outer end of the spindle 19 is a sprocket wheel 20 driven
by a chain 21 from another sprocket wheel 22 fixed on the hub of the belt
pulley 23 of the press. The inner end of the spindle 19 is provided with a
bevel pinion 24 which drives a bevel wheel on the inner end of the spindle 18
whose outer end has a sprocket wheel 25 running loose thereon, and geared
to the sprocket wheel 5 by a chain 26. The hub of the loose sprocket wheel 25
is provided with clutch teeth to engage with similar clutch teeth on a knob 27
that can be slidden on a feather on the spindle 18. A spring latch pin concealed
within the said knob holds it either in or out of engagement with the sprocket
wheel. The inking roller and agitator can therefore be instantly stopped by
merely pulling the knob out and started by pushing it in.
The gearing is supported on the spring 17 in order that it may automatically
adapt its position to variations in the vertical adjustment of the ink reservoir
effected by the table adjusting screw and to the small downward motion of the
reservoir caused each time by the passage of the depressing devices over the
discs or rollers 15. The spring 17 also enables the chain 26 to be readily dis-
engaged from the sprocket wheel 5 so as to allow the reservoir to be removed.
The object of driving the inking apparatus from the belt pulley 23, is that when
the said pulley is disconnected from the main shaft in order to bring the press
to rest, the inking apparatus shall still continue in motion, it being necessary
with many kinds of ink or colouring matter to keep the same in constant motion
or agitation to prevent its drying on the rollers and to keep it thoroughly mixed
and avoid the sediment or solid particles settling to the bottom of the reservoir.
At the same time the motion can be stopped, if required, by the clutch knob 27,
as before described.
Although I have thus described and illustrated a convenient arrangement

of variation.
