PRINTING PRESS INKING MECHANISM

This invention relates to a printing press inking
mechanism. In printing presses used for proof
printing, a bed on which the type is carried is
moved underneath a pressure cylinder, the rota
tion of the cylinder and the movement of the bed
taking place simultaneously. Paper is fed over
the cylinder so as to be pressed against the type
which must have been previously inked in order
that the printing may appear upon the paper
on the side thereof presented to the type.
In our invention we have provided a mecha
nism which is permanently installed upon the
printing press and with which the type may be
inked on rotation of the cylinder, and simulta—
neous movement of the bed underneath the cyl

'
Means are also provided whereby when the
inking rollers are raised from contact with the
type the inking rollers and the intermediate
spreading rollers are simultaneously separated
from each other. This separation of the rollers
is desirable when the press is to be out of use
‘ for some time.
The inking rollers being made of
soft composition having a tendency to become
distorted under continued pressure, therefore it
is desirable to separate them during the period
of non-use. This separation of the rollers also
facilitates the cleaning of the rollers after use
of the press.

At the lower .endportion and rear
.side of each arm'll a concave recess 20, substan-,
tially semi-circular in form, is made (see Fig. 1). V50
At the inner ‘side of each of the bell crank
levers described, a supporting bracket 22 is lo

provided with a forwardly extending arm 23 be
low which the bracket is continued in a section
24, terminating at its lower end in a forwardly
operable crank or lever 46 to rock the same. On
the lever two rollers 41 are mounted short dis
tances from the shaft 45, one above and the other
extending substantially horizontal member 25,
below the shaft. At the opposite end of the rock
shaft 45 (in Fig. 5) a collar 48 is secured which
likewise carries similar rollers 41a similarly posi
tioned. Rocking the shaft, for instance in a
included in which are two spaced apart sleeves 26.
In each sleeve a vertical post 21 is mounted for
vertical adjustment by means of suitable ad
justing screws and hand wheels 28 as shown in
Figs. 1 and 2. Bars 29 having integral bearing
10 blocks 30 at their upper sides are adjustably
mounted on the posts by a pin and slot connec
tion shown at 3|, whereby the bearing’ blocks 30
may be adjusted horizontally toward or away
from each other. The bearing blocks 30 serve
as bearings for the ends 32 of shafts on which
inking rollers 33 are carried. The inking rollers
extend .across and above the table 3 and the type
I carried thereby. In the position shown in Fig.
1 they ride upon the upper type surfaces of the
type I and transmit ink thereto as the type
is moved longitudinally with the bed 3underneath
the cylinder ||.
The forward free end of each arm 23 has a
journal 34 slidably mounted therein to the upper
side of which a hook 35, complementary to the
hook 2|, is connected. A covering shroud 36 is
also integral with or otherwise suitably connected
with each journal block 34 and has oppositely
extending arms 31 at its inner end in which the
reduced diameter ends 38 of small rollers 39 are
mounted being located directly over the imme
diate inking rollers 33. A shaft 40 is rotatably
mounted in. the journal blocks 34 on which a
spreading roller 4| is carried.
This shaft has
counterclockwise direction, brings the upper
rollers 41 and 41a against the front sides of the
housing supports M (Fig. 1) and the lower rollers
41, 41a enter the concaved recess 20 in the arms
|'|, thereby rocking the shaft |6 counterclock
wise and swinging the inking mechanism from
the position shown in Fig. 1 to that shown in
Fig. 2. If the hooks at 2| are engaged with the
hooks 35 the spreading roller 4| and associated
parts are elevated above the inking rollers 33 as
in Fig. 2. However, the hooks 2| may be disen
gaged from the hooks 35, in which case the spread
ing roller 4| and the parts associated therewith
will remain in the same relative position with re
spect to the inking rollers 33.
With this construction, when the press is to be
out of use for some time the crank 46 is turned as
described to swing the inking mechanism to the 25
inoperative position as shown in Fig. 2. In this
position the spreading rollers 39 and 4| are sepa
rated from the inking rollers 33 and to assume
this position the hooks 2| are in engagement with
30
the hooks 35.
Before a printing job is done the inking rollers
33 are in raised position with the hooks 2| dis
engaged from the hooks 35 leaving the spreading
rollers 39 and 4| in contact with the inking rollers.
C23 til both a reciprocating longitudinal movement and
The spreading rollers are smeared with the proper
a rotary movement. The mechanism for giving
longitudinal movement to the shaft and the roller
amount of ink and then the cylinder | | is rotated,
moving the bed thereunder and rotating the
spreading rollers which spread the ink onto the
inking rollers. During this movement the inking
thereon is not described as the same is not new.
The journal blocks 34 which carry the shaft 4!]
40 may be lifted in suitable guide slots in the arm
23 through the connection of the hooks at 2| to
the hooks at 35 and on rocking movement of the
rock shaft H5 in a counterclockwise direction,
thereby lifting not only the spreading roller 4|
but also the rollers 39, the covering shroud 36
and arms 31.
A gear 42 having a relatively wide face to per
mit the longitudinal reciprocation described is
?xed on shaft 49.
It is in mesh with an idler
50 pinion 43 mounted at the inner side of the one of
the brackets 22. Pinion 43 is in engagement with
the idler gear 44 similarly mounted and carried.
The gear 44 is adapted to engage and mesh with
the gear Ill at the end of the cylinder II. From
this construction it is evident that when the cyl
inder II and attached gear ID are manually ro
tated by turning the shaft l2 in a clockwise direc
tion the spreading roller 4| is actuated. Such
roller lies between and above the inking rollers
60 33 and is designed to have contacting engage
ment with both, the adjustment of the inking
rollers 33 toward or away from each other pro
viding such ability of simultaneous contact. The
rotation of the gear l0 drives (and also recipro
cates) the spreading roller 40 so as to evenly and
smoothly spread any ink applied to such spread
ing roller over the immediate inking rollers 33.
The inking rollers 33 in turn apply ink to the
upper faces of the type presented to such rollers.
The gearing, including the gears 42, 43 and 44,
rollers 33 are raised so that they do not contact
the type as it passes thereunder. The cylinder
is rotated back and forth until the ink is spread
su?iciently.
.
The inking rollers are then lowered ready for
a printing job.
With the inking rollers raised from the plane
of the face of the type and the spreading rollers
raised relative to the inking rollers the cleaning
of the rollers after a printing job’ is made easier
for the rollers are out of contact with each other.
The construction described is of a very prac
tical, durable and useful character and has
proved its value in service. The invention is de
?ned in the appended claims and is to be con
sidered comprehensive of all forms of structure, 55
coming within their scope.
