when the sleeve 28 is moved axially by handwheel 55 to permit such engagement. The clutch 3| is integral with a gear 32 freely mounted for rotation on the sleeve 24 and has a shoulder 33 abutting the shoulder 34 of sleeve 24 and a corresponding shoulder formed by the collar 34' on the opposite side secured to sleeve 24. The teeth of gear 32 mesh with a gear 35 keyed to the shaft 36 rotatably mounted at its opposite ends in the bearings 31 and 38 in the frame 8. Gear 35, which forms no essential part of the present inventions is merely illustrated as it happens to be part of the completed machine and transfers power for other operations of the mechanism.

Power from a source (not shown) drives gear 32,

which, when the clutch jaws 3| and 30 are in 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 |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 invention 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 axial movement by the lugs 44 and 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 described in detail above, this angular adjustment of the sleeve |5 with respect to sleeve 24 produces a corresponding adjustment of the drum I.

Referring now again to Figure 1, the method of rotating the rack 41 for producing this adjustment 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 59mesh with the internal teeth of worm gear 5|. The outer teeth 82 of worm gear 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 through the worm 63 rotates the worm gear 6|. Inasmuch as the worm gear 8| in turn is fixed against axial movement between the block 81 at one end thereof fixed worm 68.

and the worm 88' at the other end thereof, and the screw 58 in turn is restrained from rotation by. the slot or keyway 81' and cooperating key block 81 as shown in Figure 4 rotation of worm. gear 6| will cause an axial movement of the screw member 58, causing a corresponding axial movement of the rack 41. Rack 41 in turn draws gear 43 for producing fine adjustments of the drum I as has already been described. Although rack 41 rotates with sleeves l5 and 24, in the 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 adjustments may therefore be obtain d while the apparatus is in operation. a

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 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 The teeth 14 of worm 88 mesh with the worm 15. pinned to the shaft 16 for rotation 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 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 extending brace 8|. Inasmuch as the worm gear 68 is fixed against axial movement in the housing 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 corresponding movement of shaft 55. As the shaft 55 is moved axially it carries with it its bearings 12 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 obvious. Normally, for producing rough adjustments 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| 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 handwheel 29 is operated to move sleeve 28 to the left until the clutch jaws 30 and 3| engage. Thereafter, with the apparatus in operation, by observing printing operations, adjustments may be made first 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 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 to move the shaft l2 and drum. l axially required amount.
