Many devices are in use whereby cylinders of printing presses .canbe adjusted .laterally as well as circumferentially for the pur-pose oi bringing .the .printing plates into register with-each other, but not any of the mechanisms known to me .have .incorporated therein, provisions ...for lelirni- .natingall playin :the .adjusting members when the respective formcylindersare locked in their adjusted positions. rlhis provision rof positive locking means whereby `all :manufacturingtolerances Yin the adjusting mechanism, wear inthe operating parts, etc. can -be compensated for is highlydesirablein order to-secure suchfcylinders `againstany unintended lateral shifting -while the press isin operation.

Therefore, .itis .one `of .the pr-imary yobjects of my invention to providea device which will not only accomplish lateraladjustment .of a 'printing cylinder but will .also .include means for locking the cylinder securely in its .adjusted position.

Another object of my inventionis Yto provide alocking device which'will besimple in construc- 'tion and efficient in .its operation.

A still further object of .myinvention resides in the provision of adjusting means for cylinders, having indicia associated .therewith to lindicate the degree of adjustment Vimparted Atov-al cylinder.

In the particular embodiment il- Alu'strated, the journalling-means for the cylinder Vcomprise 'the-combination radial and thrust bearings Iv51and I6 and their respective housings 4I1 and lwhichv are mounted on the journal members II and I2 respectively. On the right end fof the cylinder, as viewed in this gure, the housing |8 and its associated bearings I6 are maintained in .position Without radial or end .clearance on the journal I2 yby means of the `collar .I9 whichfis held in vposition by the-nut 2 I. The arrangementat -the other end .of the cylinderis quite ysimilar with the housing I1 and bearings .I5 being rsecured in position on the journal member I I by the collar 22 and nuty 23. As a'reslt, .the bearings AI5 and I6 and housing Il and I8 `form an integral part of -the Acylinder' assembly, .permitting independent rotary motion ci the cylinder., but being movable as a unit with lsaid cylinder when lateral adjustments thereof aremade n v .For this reason,the housing Hand I8'are slidablymoiinted 'inthe frame members I3 and Il! Lto enable'th'em to move laterally` with the cylinder, but they are restrained from rotating "therewith by 'the keys 2li and '25 which fit into grooves yprovided"therefor in the journal openings o'f'the frame members I3 'and I4 and in the respectiveliou'sings 'Hand I8. y y The bearings lhousings I1 and I8 are valmost `identical in construction withthe exception that 'housing Ij'|,"o`n the l'feedside of thepress, 'is provided with threads '21 yon Aa portion `of 'its vpcriphery which projects 4'beyond the side Vframe member I3. A pair of annular, externally vtoothed "'n'iits "-28 `and `29 "are adju'stably mounted `/on 'the `'threads '21 of the `housing H vand as 'will be ei;- `planed`rnore ful-ly vhereinafter, these nuts vare factuated t'o eilect :axial adjustment of the cylinder'when the lvpress fis `in `operation as Well -as 'when it isistopped and they are yalso utilized fior llocking'th'e cylinder securely in its adjusted `position `to `prevent any unintended axial movement thereof while the press is in operation.

An :auxiliary rframe member 3|, which consti- .tutes an essential part of the adjusting and locking mechanism, is tted over the annular nuts 28 and 29 andis .secured in .position on the .side frame I3. Frame member 3| :provides support for the stub Vshaft 32 on which are rotatably mounted the intermediate gears 33 and 34 which are arranged to mesh with the teeth of the annular nuts 28 and 29 respectively, see Figures 1 and 4.

Also fixed to the lower end of frame member 3| is the horizontally disposed member 36 having an axial bore in which the hollow shaft 31 is rotatably mounted. The inner end of said shaft projects through the frame member 3| and is provided with splines 38 which mesh with the intermediate gear 33. To the free end of this shaft is secured the crank 39 comprising levers 40 and 4| and the handle 42. Consequently, when crank 39 is rotated, a relative angular displacement of the nut 28 will result due to the meshing relation of the splines 38 with the gear 33 and the teeth of nut 28. It will also be noted that the levers 40 and 4| are pivotally connected by means of the stud 43 so that while the press is in operation, lever 4| can be moved to an inoperative position as shown by the dotted lines in Figure 5 to make other press adjustments more accessible. Lever 4| carries a spring urged plunger 44 which is arranged to engage the recess 46 in lever 40 when the lever is in its operative position or the recess 41, also in lever 40, when in its inoperative position.

'Ihe annular nut 29 is actuated in a, similar manner. A shaft 48 is rotatably mounted within the hollow shaft 31 and is provided at its inner end with the pinion 49 which meshes with gear 34. At its outer end shaft 48 carries the lever 5| which is provided with a spring urged plunger 52 by means of which lever 5| is connected to crank 39 for adjustment purposes. As shown in Figures 2 and 3, the pin 52 engages the recess 53 in lever 40 when an adjustment is to be made and it is released when the levers are to be moved to their locking positions as shown in Figure 5. Lever 5| is also provided with an indicator 54 which registers on the dial 56, the axial movement of the cylinder in thousandths of an inch.

When a lateral adjustment of the cylinder is to be made, the mechanism is first released for adjustment by holding lever 5| in position while crank 39 is turned clockwise until the plunger 52 drops into the recess 53 in lever 48. The coacting lever 5| and crank 39 are then interconnected and will move as a single unit to effect adjustment of the cylinder.

The independent clockwise movement of crank 39 also rotates the hollow shaft 31 which, through its splines 38, also rotates the intermediate gear 33 and thereby nut 28. This rotation of the nut 2B causes it to move from its locking relation in Contact with the frame member 3|, as shown in Figure 4, to a released position as shown in Figure l wherein it is spaced from said member 3| and the nuts 28 and 29 are then free to be rotated in unison.

To move the cylinder I laterally to the left for instance, as viewed in Figure l, crank 39 and therewith lever is rotated clockwise until the indicator 54 registers, in thousandths of an inch, the desired degree of movement. 'I'his rotation of the crank 39 and lever 5| in unison effects a relative clockwise rotation of the nuts 28 and 29. Because the nuts 28 and 29 are restrained from moving axially on the housing i1 by the outer surface of the side frame |3, the force is exerted against the frame I3 and transmitted through the nuts 28 and 29 to the housing I1 causing the housing and therewith the cylinder I0 to move laterally to the left. An adjustment of the cylinder to the right would be accomplished in the same manner, except that crank 39 would be turned counterclockwise and nut 28 would then exert pressure against the auxiliary frame 3| to urge the cylinder |0 to the right.

After the desired adjustment has been accompushed, the complete mechanism is locked securely against any unintended lateral movement. Plunger 52 is withdrawn from its seat in lever 40 and while lever 5I is held stationary, crank 39 is moved counterclockwise until nut 28 is set tightly against the inner face of the frame member 3| as shown in Figure 4.

It Will be readily apparent that with the nuts 28 and 29 in firm contact with the frame members 3| and I3 respectively, the cylinder Il] is effectively locked against any unintended lateral movement and any free play in the associated adjusting mechanism will be positively eliminated.

After the `cylinder is securely locked in position, lever 4| of crank 39 is moved to its inoperative position, as indicated by the broken lines in Figure 5, by releasing the plunger 44 from the recess 46 in lever 40 and turning lever 4| until said plunger drops into the recess 41.

While I have herein disclosed a preferred embodiment of my invention, it is merely by way of example and I do not wish to be limited to specific details of construction. It will be understood that modifications in the design and arrangement of parts may be made without departing from the spirit of my invention or the scope of the appended claims.
