A plurality of such drums are usually arranged
to operate on an advancing sheet of material.
These operations must register on the sheet in a
predetermined relation. Thus,for example in
10 printing different colors from a succ ssion of such
cylinders, the cylindersmust opera e in a fixed
relation so that the printing will \coordinate
properly. Similarly‘ in the‘ case of slotting and
printing, there must be a corresponding ?xsd
mechanism of Figure 4. ' _

Referring now more specifically to Figure 1,
printing drum l cooperates ‘with the platen 2_ for
printing on sheet fed therebetween. Inasmuch
as the drive for the‘drum 2 is obtained directly‘lo
from the Source of power employed, the details
of this drive\are not disclosed since there is noth

movement of the rack 41. Rack 41 in turn draws
gear 43 for producing ?ne adjustments of the
drum I as has already been described. Although
rack 41 rotates with sleeves l5 and 24, in the 10
manner that will now be obvious, about screw
59 on bearings 1|, this entire mechanism can be
shifted axially and it will be obvious that adjust

engagement, produces a corresponding rotation
of the sleeve 28. Sleeve 28 keyed to the sleeve 24
in turn drives this sleeve, and sleeve 24 through
its connection to sleeve l5 by way of the screw
20
|1 drives the latter, which in turn is connected
through a key It to the shaft extension |2,
thereby driving the drum I.
The angular adjustment of the drum l'wi’th
respect to drum 2, in accordance with my inven
25 tion by means of the driving connection between
the sleeves 24 and I5 illustrated in detail in
Figure- 2. ‘The screw |1 meshes with internal
teeth 42 of a gear“. Gear 43 which is securely
held against axial movement between lugs 44 and
45, which form an integral part of sleeve I5, is
provided with external teeth which mesh with
the teeth 48 of the rack 41 iFigure 1). Screw I1
is provided with a keyway 5| (Figure 2) which
engages a key 5|’ extending from sleeve |5 to
prevent "rotation of the screw l1.
_
As the rack 41 is moved axially in a manner to
be described hereinafter, the gear 43 is rotated.
Inasmuch, however, as the screw I1 is restrained
from rotation, and gear 43 is prevented from any
40 axial movement by the lugs 44 and 45 between
which it is held, the only possible movement is
an axial movement of screw H with respect to
gear 43. The head of screw H in contact with
block l8 thus produces a tangential force on
sleeve |5 as a result of which a rotation of sleeve
I5 is produced together with a ‘rotary movement
of the entire connection including the screw l1,
gear 43, and lugs 44 and 45 as illustrated in
Figure 3 by ‘the new position which these parts
have taken up. Since the rotation of sleeve l5
produces therewith a corresponding rotation of
the drum I through the driving connections de
scribed in detail above, this angular adjustment
of the sleeve |5 with respect to sleeve 24 pro
duces a corresponding adjustment of the drum I.
Referring now again to Figure 1, the method
of rotating the rack 41 for producing this adjust
ment will now be described. Rack 41, freely
mounted for axial slidable movement in sleeve
| 5 but engaged for angular movement through
keyway 41’ in rack 41 and key l5’ secured in
sleeve l5 which in turn is slidable on the shaft
55, has one end thereof hollowed as at 58 and
has at this end an internal threaded portion 51
which engages ‘the threads of a block 58 rotatable
on screw 53 through the bearing 1|. The teeth
58 of screw 59‘mesh with the internal teeth of
worm gear 5|. The outer teeth 82 of worm gear
70 5| in turn mesh with the worm 83 which is keyed
to shaft ‘65. One end of shaft 55 is secured to
the handwheel 56 (Figure 4). As the handwheel
86 is rotated, shaft 65 through the worm 63
rotates the worm gear 6|. Inasmuch as the
76 worm gear 8| in turn is fixed against axial move
ment between the block 81 at one end thereof
'
a
15
In order to obtain longitudinal adjustments
of the cylinder I, the shaft extension- | 2 is
mounted for rotation about bearings 12 mounted
in turn on shaft 55. Shaft 55, which is free to
rotate in bearings 12 at one end and is keyed 20
to the screw 58 forming the sleeve thereof at
»
its other end, is provided with a screw member
13 at its free end which meshes with teeth in the
fixed worm 68. The teeth 14 of worm 88 mesh
with the worm 15. pinned to the shaft 16 for ro 25
tation therewith. Shaft 18 in turn is connected
to the handwheel 11 for rotation thereby. As the
handwheel 11 rotates to drive shaft 16, the worm
15 rotates worm gear 68. Worm gears GI and 88
are mounted in a‘ housing 18, which consists of so
the upper member 19 and lower support member
80 arranged so as to form bearings for the
worm gears 6| and 68 and their corresponding
worms and handwheels. The entire unit is
mounted to main frame 6 by means of an ex
tending brace 8|. Inasmuch as the worm gear
68 is fixed against axial movement in the hous
ing 18 which also houses the worm gear 8|, as
the worm gear 68 rotates, and inasmuch as
screw 13 is locked against rotation by reason
of the engagement of the keyway in screw 59 by
the key 64 of shaft 55 an axial movement of
the screw 13 is produced producing a correspond
ing movement of shaft 55. As the shaft 55 is
moved axially it carries with it its bearings 12 45
and the housing 18 to move shaft extension l2
and drum | longitudinally for displacement with
respect to drum 2. Shaft |2 by reason of the
key “5 which engages keyway I8’ is adjustable
longitudinally with respect to the sleeve l5.
The operation of my mechanism will now be
to
obvious. Normally, for producing rough adjust
ments of the drum I, I disengage clutches 30 and
3| by the handwheel 28 which carries the sleeve
28 to the right. With the clutches 30 and 3| 65
disengaged handwheel 28 may be rotated to in
turn rotate the drum | until an approximate
adjustment has been obtained. After the rough
adjustment has been accomplished, the hand
wheel 29 is operated to move sleeve 28 to the 60
left until the clutch jaws 30 and 3| engage.
Thereafter, with the apparatus in operation, by
observing printing operations, adjustments may
be made ?rst with the handwheel 65. Operation
of the handwheel 68, as explained above, results
‘in a longitudinal movement of the rack 41 which,
in turn, produces a rotating movement of gear
43. The rotation of the gear 43, because of the
non-rotating condition of worm l1 and because
of the restraining of gear 43 between the lugs 70
44 and 45, can be translated only into a rotation
of the connection between sleeves 24 and IS with
respect to sleeve 24. Similarly to produce axial
movement of the drum, the handwheel 11 is
operated, which operates through the shaft 55 75
