11 Claims. (Cl. 101-219)
This invention relates to printing machines.
It is an object of this invention to provide a
constant speed printing roll with a constant speed
of paper sothat the successive printing impressions
made by the roll are equi-distant from one an
other, in combination with a supporting roll pro
vided with a resilient covering and traveling at a
lesser speed, the impressions upon which latter
roll are always progressively at different places
10
on the surface thereof.
‘
-
It is a further object of this invention to pro
vide a paper supporting roll having a resilient
ink resistant cover, which roll is adapted to sup
port paper against the impression surface of a
ll printing roll and which supporting roll is adapt
ed to be driven by the frictional engagement of
the printing roll therewith.
It is a further object of this invention to pro
vide such a paper supporting roll which travels at
20 a lesser speed than the printing roll whereby to
produce a constant slip of the resilient surface
of said roll with respect to the inside surface of
the paper supported thereby against the impres
sion surface of the printing roll.
25
It is a further object of this invention to pro
vide means for regulating the pressure between
said rolls with great accuracy and within prede
termined limits.
It is a further object of this invention to pro
30 vide inking means for the printing roll comprising
an ink well and distribution rollers, one of said
distribution rollers being engaged by a smaller
steel roller to produce a ?nal smooth spread of
ink on the roller surface in order to prevent un
35 even application of ink to the printing roll.
It is a further object of this invention to pro
vide a pair of printing rolls and resilient paper
supporting rolls, said printing rolls being driven,
in synchronism, from a common source of power
40 and adapted to contact different peripheral por
tions of the resilient roller, one of said printing
rolls having thereon printing plates adapted to
print a ticket form of one color and the other of
said rolls having printing plates or patches there
45 on and adapted to provide additional printed
matter on the tickets printed by the ?rst roller
It is a further object of this invention to pro
vide means whereby the adjustment of one end
of said roll will be accompanied by like adjust
ment of the other end, wherein misalignment of
such roll with respect to the axes of the printing
rolls is prevented.
These and other advantages will appear from
the following description taken in connection 10
with the drawings.
Referring to the drawings:
Figure 1 is a front elevational view of a ma
chine embodying the principles of my invention;
Figure 2 is an elevational view in section taken
through the centers of the printing rollers and
paper support roller, on the line 2-2 of Figure 3;
Figure 3 is a side elevational view, partly in
section, taken on’ the line 3-3 of Figure 2;
Figure 4 is a side elevational view, partly in
section, taken along the line 4—4 of Figure 2;
Figure 5 is a top plan view of the machine, as
shown in Figure 1.
Referring to the drawings in detail, the roller
support frame comprises a pair of side standards
I secured in rigidly spaced relation by means of
braces 2. Extending transversely of the frame
and journaled in the side standards I are shafts
' 3, 4 and 5. The shaft 3 is journaled in ?xed bear
ings 6 at its ends and carries integrally secured
to one end thereof the drive pulley ‘I. Rigidly
attached to the central portion of the shaft 3 is
the printing roll 8 which is adapted to have
printing plates 9 rigidly attached thereto. Also
rigidly secured on the shaft 3, adjacent one end 35
of the roll 8, is a gear Ill. The shaft 5 has the
opposite ends thereof journaled in ?xed bearings
II in the side standards I disposed below the
bearing 6 therein. The shaft 5 has rigidly se
cured to the central portion thereof a printing 0
roll or patch roll I! which is adapted to have
printing plates or patches l3 rigidly secured
thereto. Rigidly secured to the shaft 5, adjacent
one end of the roll I2, is the gear [4.
The opposite end portions of the shaft 4 are ro 4
tatably received in bores l5 of bearing drums l6,

apertures 20. The bores I5 in the hearing drums
I6 are ecentrically disposed. Rotatably mounted
on the mid portion of the shaft 4 is a roller having
a rigid core 22 and a resilient covering 23. Se
cured in recesses in the radial end faces of this
roller are outer ball bearing races 24 which are
adapted to be supported by balls 25 which are
supported by inner ball races 26 mounted on the
shaft 4. The outer ball races 24 are secured in the
10 recesses in the roller core 22 by means of retainer
plates 21 which are secured to the radial end
faces of the core 22 by means of screws or studs
28. Rigidly secured to the shaft 4, adjacent one
end of the roll, is the gear 29. This gear meshes
with the gear II] on the shaft 3 and the gear I4
on shaft 5 and thus causes shafts 3, 4 and 5 to be
rotated when power is applied to the pulley ‘I on
the shaft 3. One of the retainer plates 21 has an
elongated cylindrical portion 30 having jaws 3|
20 therein, which jaws are adapted to engage teeth
32 on a clutch member 33 which is splined on the
shaft 4. By means of the clutch member 33, the
paper support roll is freely rotatable on shaft 4
when the clutch member 33 is disengaged and the
25 paper support roll may be connected to the shaft
by engagement of the teeth 3| and 32 and the
paper support roll rotated in synchronism with
the printing rolls 8 and I2 respectively because of
theengagement of the gears I0, 29 and I4, de
30 scribed above.
The eccentricity of the bores I5 with respect to
the cylindrical bearing surfaces I9 of the bearing
drums I6 is relatively slight and provides slight
adjustment which is accommodated by the loose
35 engagement of the teeth of the respective gears
I0, 23 and I4. ‘The adjustment of the shaft 4 is
accomplished by means of a pair of worms 35
which are engaged with the Worm gear surfaces
IT on the eccentric bearing drums (I6. The
40 worms are supported in suitable brackets 36 at
tached to the standards I and have bevel gears
31 rigidly attached to the rear ends thereof. The
bevel gears 31 are adapted to mesh with similar
gears 38 which are supported on and rigidly se
45 cured to shaft 39 which has the ends thereof
journaled in ?xed bearings in the frame stand
ards I. The forward end of one of the worms 35
has a shaft portion 40 extending therefrom, which
extends forwardly beyond the front portion of
50 the frame and has the handle 4| and pointer 42
rigidly secured thereto. The pointer is adapted
to cooperate with radially disposed graduations
on an indicator plate 43 which is secured by means
of screws 44 to a ?ange 45 on one of the frame
55 standards. The position of the pointer 42 in the
normal position of the paper support roll is shown
in Figures 1 and 5, particularly. By manipula
tion of the handle 4|, the position of the indicator
42 may be changed as desired, which movement
60 will cause a rotation of the shaft portion 40 of one
worm 35 in one or the other direction. This will
cause rotation of the corresponding gear 31 which,
through gear 38, rotates shaft 39 which has \the
second gear 38 rigidly secured thereto and rotat
65 able therewith. Rotation of the second gear 38
will cause rotation of the second gear 31 which
will cause the second worm 35 to be rotated in the
same direction as the ?rst worm 35. The joint
rotation of the worms 35 will cause like rotation
of the eccentric bearing drums I6 in the cylindri
cal bearing surfaces I9 of the standards I.
The graduations on the indicator plate 43 each‘
preferably indicates .001 inch. Secured at each
end to the back of a standard I by means of
75 studs 46 is a pair of similar plates 41, which have
forwardly extending brackets 48 secured thereto
by means of screws 49. These plates are spaced
a slight distance below a pair of braces 2 in the
form of rods which are described above. Each of
these brackets 48 is adapted to support three re
silient inking rollers 50 having their cores or
pintles 5| supported in notches 52 in the brackets
48, as shown particularly in Figure 3. Journaled
at each end in one bracket 48 is a steel roller 53
which is adapted to have the foremost resilient 10
roller 50 rest freely thereupon, which foremost
roller is adapted to contact the printing plate 9
on the printing roll 8. Adapted to be adjustably
secured on the brace or rod 2 by means of screw
54 is an ink well or reservoir 55 having journaled 15
therein a roller 56, preferably of metal, which is
adapted to contact the uppermost resilient inking
roller 50. When the printing roll 8 is rotating and
the ink well or reservoir 55 is ?lled with ink, the
rotation of the plate 9 causes rotation of the 20
foremost roller 50 which rests upon the steel‘or
metal roller 53. The rotation of the foremost re
silient roller 50 is transmitted through the inter
mediate resilient roller to the uppermost resilient
roller 5|], which roller, because of its contact with
the distributing roller 56, causes ink to be trans
mitted from the interior of the ink well or reser
voir 55 by means of distributor roller 56 to the up
permost inking roller and thence to the inter
mediate inking roller, from whence it is trans
ferred to the foremost inking roller.
30
With the direction of paper feed, as indicated
by the arrows in Figure 4, the rotation of the
foremost inking roller 50 will be clockwise and
freely rotatable metal or steel roller 53 will be 35
rotated counterclockwise. The metal roller 53
will thus prevent the foremost inking roller 50
from transferring excessive quantities of ink to
the plate 9 of printing roll 8 because this metal
roller 53 will cause the ink to be uniformly dis 40
tributed in a thin ?lm progressively over the cir
cumference of the foremost inking roller 50 be
fore it reaches the printing plate 9 on the roll 8.‘
The ink wells or reservoirs 55 and rollers 56, as
well as the resilient inking rollers and ink distrib- ~‘ '
uting metal rollers 53 are identical for the re
spective printing rolls 8 and I2 and the inking
units operate in the same manner, although I
preferably use inks of different colors in the
respective ink wells or reservoirs 55.
50
When it is desired to adjust the press, the
clutch member 33 is preferably engaged, having
the teeth 32 thereof engaged with the teeth 3| to
connect the paper supporting roll for rotation
with the shaft 4. The shafts 3, 4 and 5 are then
rotated together. When the rollers have been
suitably adjusted by means of the handle M and
warm mechanism connected therewith, the
clutch member 33 is disengaged and the paper
‘supporting roll is allowed to rotate freely with 60
respect to the shaft 4. The rotation of this
roller is caused mainly by the movement of the
paper which is caused to move by the rolls 8 and
I2. There is, however, a slight frictional rota
tive force exerted on the paper support roll be 65
cause of the friction existing in the ball bearings
which support it on the shaft 4, which is ro
tated with the shafts 3 and 5.
There is a cer
tain degree of slippage which occurs between the
resilient cover 23 of the paper support roll and
the rear surface of the paper, which prevents
the respective portions of the printing plates and
patches 9 and I3 respectively from abutting the
resilient surface 23 at the same points on con
tinued rotation. The printing plates or patches
3
2,136,683
I3 remain in synchronism with the printing plate
9 on the roll 8 because of the gearing connecting
the shafts 3 and 5, to which the rolls 8 and I2
are rigidly secured. These patches I3 are sub
stantially smaller than the printing plate 9 and
therefore a plurality of different patches may be
used, as is shown in Figure 4. If desired, the
whereby impressions of the printing roll occur
progressively thereon, during operation, and a
clutch in said last-named means adapted to be
selectively operated to disconnect the driving
means from said supporting roll.
3. In a printing machine, a roll having a print
ing plate attached thereto, a roll adapted to sup
inking mechanism for the printing roll I2 may
port paper against said printing plate, and means
be removed and the patches I3 removed from
10
the printing roll I2 or, if desired, the same pro
cedure may be followed in omitting the printing
by the printing roll 8. The metal or steel ink
selectively operable to cause said supporting roll
to rotate at a different speed from said ?rst roll
to cause the impression of said plate thereon to
occur at different places thereon, or to rotate
free thereof, and means to adjust said rolls to
vary the pressure between said second roll and
spreader rollers 53, as before pointed out, exert
15 a ?nal spreading action upon the ink carried
on the periphery of the foremost inking roller
50.
The covering 23 of the paper support roll may
be of any desired resilient material, such as
20 rubber, but I preferably use a material having
'the desired properties of rubber and in addition
a substantially higher resistance to printing inks,
such as synthetic rubber, and of these rubbers I
prefer “Duprene” which has been found by me
25 to be entirely satisfactory. The external sur
face of the covering 23 must be very smooth
and hard so as to present the least possible fric
tion to the paper ‘I, and I have found that syn
thetic rubbers and especially “Duprene” give a
30 smooth, hard surface and a body of desired resil
iency in combination with high resistance to inks,
but it is to be understood that the use of equiva
lent materials is comprehended by me. By
means of the handle M and pointer 43, I may se
35 cure exact adjustments of the paper supporting
roll with respect to the printing rolls 8 and I2,
and the loss of adjustment is prevented by the
use of worms 35 and worm gear surfaces I'I.

It will be understood that the above described
structure which is illustrated. in the drawings is
susceptible of variation within rather wide
