LINKING MECHANISM FRINTING MACHINES.

Application filed February 9, 1922,

To all whom it may concern:

Be it known that I, FRANK C. MAI:- QUARDT, a citizen of the United States, residing at the borough of Brooklyn, in the city of New York, county of Kings, and State of New York, have invented certain new and useful Improvements in inking Mechanisms for Printing Machines, of which the follow ing is a specification, reference being had therein to the accompanying drawings, which form a part thereof.

My invention relates to inking mechanisms for printing machines, and more particularly to an inking mechanism adapted to have movement in its entirety with relation to the form or plate cylinder, a construction requiring adjustment of the inking rollers in relation to the. distributing roller, as Well as to the form or plate upon the cylinder.

l-leretofore in mechanisms of the character to which my invention relates, adjustment means have been provided by which the ink ing rollers applying the ink to the form or plate have been capable of adjustment with relation to the distributing roller co-operating therewith by a movement substantially radially of saiddistributing roller, andof a rectilineal adjnstmentat an angle to a radius oft-he form or plate cylinder.

With such mechanisms, during the makeready of a press, considerable difficulty has been experienced in securing the proper adjustment of the inkingjrollers, since when such rollers are iiroperly as to the distributing roller, there Was ordinarily a loss of such adjustment when subsequently adjusting the inking rollers to the plate upon the form or plate cylinder. This condition required repeated trials and readjustments to secure a proper relation of the inking rollers to the form or plate, and also to the distributing roller co-operating therewith, and could be secured only by repeatedly moving the carriage carrying the inking mechanism so as to bring the inking rollers into and out of engagement with the form or plate, andthe exercise of a high degree 0' s :illby the ressman.

7 tie the above conditions in mind, I have ngmechanismwherein adj position'ingthe inkrollers with relation to the associated ibuting roller, is such as permit the Serial No. 535,159.

subsequent adjustment ofsaid inking rollers v iith relation to the printing surface upon is shifted so as to bring the inking. rollers into engagement with the form or plate;

The construction is such that if necessaryan inking roller may be adjustedwith rela tion to the form or plate after the carriage or other support for the inking mechanism has been movedinto the operative relationto the form or plate. cylinder, means being provided whereby thesupports for the bearings for the arbors of said inking rollers-- may be locked, or set, many adjusted posi-- tion so that thereafter the carriage may be" moved freely toward and from the form orplate cylinder Without the necessity for a readjustment of said inking rollers,

When a plurality of inking rollers areemployed, which is the usual COIlClltlOIlpI provide means whereby they may: be independently adjusted, thusensuring-the proper positioning of each inking roller in the circular path of movementof the fornr or plate upon the cylinder.

' The adjustment means above referred" to co-operating With the inking rollers, may be also utilized to develop and regulate the desiredpressure by'said rollers upon the printing surface.

v The invention consists primarily in an inking mechanism for printing machines embodying therein a carriage adapted to have movement toward and from a form or plate cylinder, a distributing roller mounted therein, an inking roller associated With said distributing roller and adapted to be brought into and out of engagement With the form or plate upon saidcylinder' asdctermined by the'movement of said 'carriage; means for imparting movement to said ink ing roller radially ofsaid distributing roller to secure the proper relation'of said rollers to each other, and means for imparting movement to said inking rollercirQtimferentially of said distributing roller, and to- Wards or from said form or'plate cylinder to secure the-proper relation ofsaid inking roller t0 the form or plate, independently oi": said first named mean and'in such other novel featuresof construction and combination of parts as are hereinafter set forth and described, and more particularly pointed out in the claims hereto appended.

Referring to the drawings,

Fig. 1 is aside elevation of a portion of a carriage supporting the inking mechanism of a rotary press, showing a distributing roller and inking rollers associated therewith embodying my invention; and

- Fig.2 is an enlarged isometric view of one end of one set of inking rollers and their associated parts.

Like numerals refer to like parts in both of said views.

In the embodiment of my invention shown in the drawings, I employ two sets of ink ing; rollers receiving ink from different founts through the usual sequence of cuttin and distributing rollers. Each set of inking rollers and their associated parts, is an exact duplicate of the other, except as to minor changes of design, so that a description of but one set is essential.

The detailed construction of the carriage and the manner of moving same toward or from the impression cylinder is immaterial to my present invention, which merely contemplates such a movement aside from the mechanical expedients adopted in securing same.

In the drawings, I have shown at a fragmentary portion of such a carriage omitting all of the distributing rollers except the one co-operating directly with the inking rollers, which distributing roller is shown at 11. The arbor of the roller 11 is mounted in bearings directly in the frame of the carriage 10 and has no movement in .relation thereto. The

inking rollers

12 and 13 are adapted to operatively engage the distributing roller 11 and to convey ink therefrom to the printing surface upon the form or plate cylinder indicated at 14.

Said inking

rollers

12 and 18 are so mounted as to have movement radially of the'distributing roller 11 to permit their adjustment to secure the proper co-relation betweensaid rollers to insure the desired transfer of ink from the distributing roller to the inking rollers, said inking rollers also being adapted to be adjusted circumferentially of said distributing roller to permit their being brought into the proper inking relation to the form or plate upon the cylinder 14, without disturbing their adjustment with relation to the roller 11.

The above operative effect is secured by providing a bearing 15 for the inking roller 12 having a screw-threaded stem 16 slidably mounted in

suitable bearings

17 and 18, said stem having an adjusting nut 19 mounted thereon intermediate said bearings so as to permit the bearing 15 to be moved toward and from the axis of the distributing roller 11 by a rectilineal movement radially oi said axis.

The

bearings

17 and 18 are carried by a frame 20 mounted to rotate or oscillate about an axis concentric with that of the shaft of the roller 11, thus permitting the bearing 15 for the inking roller 12 to he moved circumferentially of said distributing roller 11, a movement which will not disturb the relation of the rollers 12 and 1 3 to the roller 11 as determined by the adjustment of the nut 19.

Slidably mounted in a lug 21 upon the carriage 10, is a screw 22 having mounted thereon adjustment nuts 23 and 21- arranged upon opposite sides of, and bearing upon, the lug 21. One end of this screw bears against the frame 20 so that rotary movement may be imparted to, or permitted in, said frame through the medium of the nuts 23 and 24: according to the direction of movement which it is necessary for the frame to have to bring the rollers 12 and 1?) into the proper engagement with the form or plate upon the cylinder 14.

The screw 22 need not be, and in the form of the invention is not, directly connected with the oscillatory frame 20, since, as will, fully appear hereinafter, under ordinary conditions said screw would serve merely as a limit stop to develop and define the desired pressure of the inking rollers upon the form or plate cylinder with the actuation of the carriage.

To permit the locking of the frame 20 in its adjusted position, 1 provide said franc with a segmental slot therein through which passes a set screw 26 cooperating with the side frame of the carriage 10.

The arbors of the inking roller 13 are mounted in a closed bearing 27 instead of in an open bearing corresponding with the bearing 15, said bearing being adapted to have movement radially of the roller 11 through the medium of a screw 28 mounted in

bearings

29 and 30 between which is mounted an adjusting nut 31. These bearings are carried by a frame 32 mounted to rotate or oscillate about an axis concentric with the axis of the shaft of the distributing roller 11, and with the axis of the frame 20, said frames 20 and 32 being mounted side by side as shown more clearly in Fig.

The frame has associated therewith an adjusting screw 33 mounted in a lug 3 carried by the carriage 10, said screw haring mounted thereon a lock. nut 35. The frame 32 is also provided with a segmental slot 36 corresponding in function with the slot 25 having associated therewith a set screw 37 corresponding in function with the screw 26.

lVhile the details as to the adjusting screw 33, lug 84 and lock nut differ from those of the screw 22, lug 21 and nuts 23 and 2 1-,

lit.)

the same operative effect is secured with in construction and mode of operation with that above described, and corresponding reference numerals therefore are applied thereto without a further description of this second inking mechanism, which, so far as this invention is concerned, may be used, or not, as desired.

The operation of the herein described mechanism is substantially as follows The carriagelO and theinking mechanisms carried thereby are moved away from the cylinder 1 L during the makeready of a. press to permit access to the form or plate cylinder, or its associated impression cylinder not shown in the drawings, or during the run ofa press, this carriage is sometimes moved away ml the cylinder for the purpose of inspection or to permit readjustmentof the plate, or for other purposes.

During themakeready of the press, clean inking and distributing rollers are mounted in the machine, which involves proper adjustment of-'these rollers with relation to each other well as to the printing surface upon the form or plate cylinder.

In an inking mechanism made in accordance with my invention, the inking rollers 12and13' are first adjusted so as to be brought into the prpper engagement with the associated distributing roller 11, by rotating the adjustingnut 19 or 31 to move the bearing or 27 radially of the roller 11 until the proper bearing contact secured between the said inking rollers and the said distributingroller. When this adjustment is once secured, it is permanent to the extent that it is not disturbed by subsequent adjustment of the inkingrollcrs to secure the proper relation thereof to the printingsurface upon the cylinder 14.

l l hcn this adjustment is secured, the

screws

22 and 33 are moved away from the frames and 32 respectively and the set screws 26 and 37 are loosened, thus permitting freedom of rotary or oscillatory movement of the saidframes about an axis concentric with thatof the distributing roller ill so that the

inking rollers

12 and 13 may be moved to ensure their proper positioning with relation to the formor plate upon the cylinder 14 by a movement circumferentially of the distributing roller 11 without a loss of the established contact relation between said inking rollers .and said distributing roller.

When the parts are in this position, the carriagecarrying the frame 10 may be moved: toward thecylinder 14, the" final movement of saidcarriage engaging the

inking rollers

12 and 13 with the printing-surface upon said cylinder.

The freedom of movement ofthe frame 20 will always be found to bring the roller 12 into engagement with the printing surface, although the roller 13 may not be so brought into such engagement. If it be necessary to adjust either

roller

12 or 13 to secure the proper engagement thereof with said surface, this is secured by means of the screw or 33 which is so actuated as to impart the desired movement to the frames 20 and:

32 and of the inking rollers mounted therein respectively, circumferentially of the roller 11, the arc of movement of said rollers causing them to approach, or permitting them to rccede from, the cylinder 1%, as determined by the direction of movement of said screws.

l i hen the proper set of the inking rollers has been secured in the manner above de' scribed, the set screws 26 and 37. may be tightened so as to prevent subsequent moven'ient of said fr m elation to the frame of the carriage 10 so that thereafter. the carriage 10 may be so moved as to bring the inking rollers out of the operative relation with the printing surface without disturbing the adjustment, since upon restoration of said rollers to their operative position, their engagement with the printing surface will be the same under all conditions.

The adjusting screw 22 serves as. a limit stop to define the oscillatory movement of the roller 12 uponengagement with the form or pla c upon the cylinder 14:, and will thus have a tendency to control the pressure between said roller and the form or plate upon the cylinder let as the carriage 10 reaches the limit of its movement toward said cylinder. The. screw 86 will have the: same eliect as to the roller The action as to each of these screws is supplemented by the set screws 26 and 37.

Since the adjustn'ient ofv the inl'ring rollers with relation to the printing surface based upon the triangular relation of the axes ofthe distributing roller 11 and the inking

rollers

12 and 13, and the capability of movement of the rollers 12 and 1?, cir cumferentially of the roller 11, which will permit said inking rollers to adjust themselves or be adjusted to the curvature of the printing surface, it is apparent that a similar effect to that herein described might be secured by having the frames 20 and 32 so associated to act as a unit, although any nicety of the proportioning and the dimension of parts and the finishing thereof, is avoided by employing independently rotatable frames under independent controls for-adjustment purposes. Furthern'iore this construction permits great nicety in the adjustment of the inking 'rollerss with irelation to the printing surface and avoids any necessity for exactitude in the diameters of the inking rollers.
