PRINTING- PRESS INKING MECHANISM.

Application filed June 18,

To all whom it may concern:

Be it known that we, JOSEPH.J. WALSER and HARLAND FANKBONER, citizens of the United States, residing in Chicago, in the county of Cook and State of Illinois, have invented certain new and useful Improvements in Printing Press Inking Mechanisms, of which the following is a specification'.

. The invention relates to printing presses, and more particularly to inking mechanism for printing presses.

Objects and advantages of the invention will be set forth in part hereinafter, and in part will be obvious herefrom, or may be ascertained through practice with the invention; the same being attained through the -means, instrumentalities and combinations pointed out in the appended claims.

The invention consists in the novel parts, constructions, arrangements, combinations and improvements herein shown and described.

The accompanying drawings, referred to herein and forming a part hereof, illustrate one embodiment of the invention, and together with the description serve to explain the principles thereof.

Fig. 7 is a fragmentary detail, on an enlarged scale and with parts in section, of the adjustable journal mounting for the ductor roll; and

Fig. 8 is a fragmentary detail, on an en-. larged scale, of the adjustable journal bearings for the ink drums.

Fig. 9 is a fragmentary detail showing the adjustable mounting for the ink foun-' tains. I

Referring to the accompanying drawings, illustrating by way of example, one embodiment of'the invention, the impression cylinder of a rotary printing couple is indicated by 1, the shaft 2 thereof being mounted in suitable bearings 3, carried upon the press frame. A cooperating form cylinder 4; has its shaft 5 mounted in like bearings 6, also carried upon the machine frame. The web 00 is run between the cylinders of the printing couple and is printed in the usual manner.

Referring to the illustrated embodiment of the inking mechanism, a ductor roller is provided cooperating with a plurality of ink fountain rollers, one ink fountain roller preferably, cooperating, with the ductor roller on either side thereof. Also, the ductor" gaging with the two ink drums to deliver the ink thereto, the, ink being delivered thence to the form inking rollers which ink the plates on the cylinder.

. In accordance with one feature of the invention, a plurality of form rollers are provided one of the form rollers receivingits ink' more directly from the source of ink supply than the other, and more particularly, in accordance with said feature of the invention, there is an additional ink drum interposed between one of the form rollers and the source of ink supply, such addi- Patented May 3, 19,21.

tional ink drum receiving its ink ,from. the

other form. roller. I

- -According to one feature of the invention,

also, there are a plurality of ink drums cooperating with a single form inking roller to impart ink thereto, andpreferably an ink drum runs in contact with such form fountain rollers, one at either side thereof,

both of which supply .ink to the 7 ductor At the other end ofits travel, the

roller. ductor roller engages with two ink drums, one-at either side thereof, to both of which ink drums the ductor roller imparts a supply of ink. These two ink drums impart ink to one form inking roller, which roller in t 11 supplies ink to the plates upon the form cylinder, and also, touan additional ink drum, which last' mentioned ink drum suppliesink to another-form inking roller,

which rollerinks theplates upon the formcylinder;

- In accordance with one feature of the invention, a vibrating, 'frictionallydriven (metal roller also cooperates with one of the form rollers to mix and distribute the ink thereon. preparatory to applying it to the plates upon the form cylinder. Associated with the foregoing are other *IIQVGl features of invention, many of which are designed to 'assist in rendering most I .highly efficient the action of the instrumentalities and mechanisms already pointed out. Referring in moredetail to the illustrated embodiment one or more ink fountains are provided, and as shown there are. two such fountains. In the ink fountain 10 is afountain rollertll, which is intermittently rotated while cooperating with the ductor roller, in the usual manner. The actuating means for the ductor roller may be of any,

' suitable or adequate form, and as illustrated herein a shaft 12 is carried in suitable-brackets 13 mounted on the machine frame, and v carried on shaft 12 a cam 14:. Coeperating with the cam 14: is a longitudinally-recipro eating rack bar 15, and carried bysaid rack bar 15 is a cam roller 16, which roller cooperates with the cam 14:. The cam roller 16 is fixed to the bar 15 in a suitable manner, as

- by ,a bolt 17. The'rack bar 15 has fixed I thereto at 18 a longitudinally extending '1 guide rod-l9, which guide rod works in a guiding aperture in the brackets or lugs 20 fixed to the machine frame. Thus as the shaft 12 rotates, rack bar'l5 and iding rod 19 are vertically reciprocated ig. 1).

g Rack be! 15 is provided with. aseries of turesof invention are'associated together in teeth 21, whichteeth mesh with a toothed sector 22 carried loosely upon a shaft 23. A roller 24 is mounted in the bracket 20, and bears against the back of the rod 15 to hold it to its work. Fixed to reciprocate with the geared sector 22 is a pawl lever 25 provided with a p'awl 26. The pawl 26 .coeperates with a ratchet wheel 28, which ratchet wheel is fixed upon theshaft 23 of the fountain ink rol exp-,ll. Thus as the rackbar l5 reciprocates, the vpawl 26 is oscillated to and fro,

thereby imparting intermittent rotary movement'to the ink fountain roller 11 when .the

3 ductor roller is in contact therewith/v Suitable means for varying the throw or. travel of the pawl 26 are provided, but are omitted from the drawings for the sake of clearness,

together with other details of the associated.

mechanism.

. In the embodied form 'a second ink foufn-l tain roller 31 also supplies ink to thejductor roll and is preferably located in.a separate ink fountain 30. Fountain roller 31 is inter-.

mittently rotated, like the fountain roller .11,

while the ductor roller is in engagement therewith. Suitable mechanism is provided for this purpose and if desired may be similar tothat already described in connection with fountain roller 11, but the showing I thereof is omitted from the drawings for thesake of clearness.

The ductor roller 32 is carried in suitable bearings in a pair of arms 33, which arms are fixed toa shaft 34 mounted in'and extending transversely to the frame of the ma- Fixed to the shaft 34 is an arm 35,

chine. and pivotally connected to the end of the arm 35 ,is a link 36, The other end of the link-'36 is pivotally connected to a bell crank lever 37, which lever ispivotally mounted at 138 on the machine frame. Bell crank lever 37 at its other end is provided with a cam roller 39, which roller coiiperates with a suitable'ca m mechanism, to be later described, whereby the ductor roller, is traveled to and fro between the fountain roller 11 and 31 and the two ink drums to which the ductor roller delivers its ink.

Means are provided by the invention for I regulating and adjusting both the position and the travel of the ductor roller to compen-,

sate for shrinkage in the size of the roller and to compensate for variations in sizedue to replacement of an old roller by a new, and to regulate the pressure or contact of. the

ductor roller with each of the respectivefountain rollers, and also with each of the respective ink drums. In the embodied formof such means, the ductor roller 32 is mounted to have adjustment longitudinally-in its bearings in the arms 33. F or this purpose, the pintles 40 .of the roller 32 arecarried in slots tLformed in the ends of the arms 33. The adjustment for the pintles in the slots 'in the a 33 is sho n in deta l in g- 7 of the drawings, wherein adjusting- screws 42 and 43 act upon the journal boxes 44 of the pintles';

Means are also provided for regulating or varying the extent of travel of the ductor roller, and the exact location of the termini -of its travel, to compensate for shrinkage and for variation in the size of new and old ductor rollers, as already explained. In the embodied form of such means, the pivotal connection of the link 36 with the bell crank lever 37 is adjustable to vary the effective throw of the. lever. As embodied, a slot 48 is formed in the end of the lever 37 whereby the pivotal bearing 38 maybe moved backwardly and forwardly in the slot, thus increasing or decreasing the throw of the arm 33, and thereby correspondingly varying and regulating the travel of the ductor roller 32. Adjusting means are also provided in the link 36, such as a turn buckle 49, whereby the length of the link 36 may be slightly varied to regulate the terminal points of the travel of the ductor roller, and to effect a smooth and harmonious actionof the mechanism. N

Means are also provided by the invention, in connection with the actuating means for i the ductor roller, for regulating and varying the dwell of the ductor roller, both at the fountain ink rollers and at'the ink drums. In accordance with certain features of the invention, such regulating means .or devices are operable or regulable independently of each other. I

In the embodied form ofsuch actuating and regulating means, there is fixed to the shaft 12 a cam 55 having a cam groove 56 formed therein. In the groove 56 operates a cam roller 57, fixed to an arm 58, which arm is fixed to a shaft 62. Fixed also to the shaft 62 is an arm or plate 60, whereon is carried a plurality of co6perating, but independently positionable cams, which cams, through roller 39 and lever 37, actuate the ductor roller 32. i

As embodied, there is formed in the arm or plate 60 a slot 61, through which .slot projects a tap-bolt 63, the tap-bolt being threaded into a cam 64, which cam is fulcrumed on the shaft-62 (see especially Fig. 4). The roller 39 runs upon the perlphery of the cam 64 (see Figs. 1 and 3) and determines the length of the dwell of the ductor roller against the ink fountain rollers. Also fulcrumed upon the shaft 62 is a cam 68, the upper portion 69 thereof being'b'ent over the outer or operative edge of the cam 64 (Figs. 3, 4 and ,5), whereby the part 69 is brought into position to cooperate with the cam roller 39.

In the plate 60- is formed a slot 70, athrough which slot projects a tap-bolt 71, which tap bolt is threadedinto the cam 68.

and is located in a slot in the cam 64 and between the plate 60 and the cam 68, to prevent jamming and clamping of the cam 64 or required for the best results in any par ticiilar case.

From the foregoing it will be seen or understood that means'are provided whereby I not only the periods of dwell of-the ductor roller at the fountain rollers and also 'at the ink drums are regulated as desired; but the extent of travel of the ductor roller, the

precise positioning of the termini of its path of travel, and the time and force of contact with each of the fountain rollers, and

also with each of the ink drums,.is adjusted and regulated as may be desired or required for the most eflicient and adequate inking l in any particular case or for any particular Work.

In accordance with features of the invention already referred to, an ink drum 76 and an ink drum 77 are provided engaging with the ductor roller 32 at either side thereof,'as shown in dotted lines in Fig. 1. 'Both the ink drum 76 and the ink drum 77 cooperate with the form inking roller 78, which form inking roller supplies ink to the plates upon the form cylinder 4 and also to an ink drum 79, which ink drum also rotates in contact with the form roller 78. Cotiperating with the ink drum 79 is a form inking roller 80, which likewise "supplies ink to the plates on form cylinder 40.

Cooperating with the form roller 78' is a ,smooth metal roller 81 running frictionally in contact with the form roller 78 and adapted to assist in the distribution of the ink on the form roller. I

The ink drums 76, 77 and 79 and the roller 81, in the preferred form, are all vibrated, and the ink drums 76, 77 and 79 are likewise positively driven, while the roller 81 is frictionally driven from form roller 7 8'. In the embodied form of vibrating means, there is fixed on the shaft 12 an eccentric 86, the strap 87 thereof being con- :nected to a rod 88. The rod 88 is pivotally connected to an arm 89, which arm is fixed to a shaft 90 journaled in a bracket 91 mounted upon the machine frame.

Fixed to the. shaft 90 is an arm 92, provided with a roller 93, which roller runs in an annularly groovedcollar 94 formed upon the shaft 95 of ink drum 77. The ink drum ispoitively rotated from the other end of its shaft, as will be later described. An arm 97 extends upwardly from the shaft 90 and 65 A spacing block 72 encircles the tap-bolt 71 is provided with a roller 98, said roller working in an annularly grooved collar 99 carried on the shaft 100 of the frictionally driven roller 81.

Fixed to shaft 90 is a geared sector 104, with which means a geared sector 105, fixed to a shaft 106, which shaft is journaled in a bracket 107 carried on the machine frame.

From shaft 106 an arm 108 extends down-, wardly and is provided with a. roller 109,

"roller 115, said roller working in an annularly grooved collar 116 on the shaft 117 of the ink drum 7 9, which ink drum, like the others, is driven from the other end of its shaft of the impression cylinder 1. An in.-'

shaft.

In Fig. 6 of the drawing is shown as arrangement of gearing for driving the various cylinders and ink drums, and therein 120 is a gear fixed to the shaft of the form cylinder 4,; and 121 is a gear fixed to the terniediate'122 drives a gear 123 on the shaft of inkd-rum 77. An intermediate 124 drives the gear 125 upon the shaft of ink drum 79, and gear' 125 drives an intermediate 126, which intermediate is carried on an arm or i arms 127 journaled on the shaft 128 of gear frame.

125. Gear 126 drives a gear 130 on the shaft of ink drum' 76.

Gears 122, 124 and 126 are shown adjustable in their bearings, thereby providing'for positioning or adjustment of the three ink drums to compensate for shrinkage of the form rollersdue-to age or wear, or replacement of rollers, or for other causes, and to regulate the pressure or contact therebetween. Details of such an adjustment, applicable to the shafts of the ink drums and of the intermediate gears, are shown in Fig. 8 of the drawing. The shafts 134 of the va-- rious gears are journaled in boxes 132, slidable in accurate apertures 133 in the press Pivoted on the shafts 134 of the gears. are screw-threaded pins or eye-bolts 135; Collared nuts 136 are threaded thereon, the grooved collar of the respective nuts engaging with a plate 137 fixed to the frame. A single detail will be suficient for all the diflerent bearings of the gearing.

The adjustment of the ink fountains to and from each other to compensate for variations in the size of the ductor roller, as to details of structure, may be of any known or suitable form. Such a form of said means is shown in Fig. 9, said figure showing a part of the mechanism shown near the bottom of Fi 1. v The ink fountains 10 and 30 are provided,

respectively, with a plurality of downwardly extending lugs 142 arranged transversely of therein a screw-threaded aperture.

rods 143, and for this purpose they are shown with squared heads 146, which are adapted to take-gear pinions, or a handle, or any other suitable actuating connection, in a well known manner. position of the fountains is so slight thatit will not interfere with the'roller actuating means.

- By reason of the two fountain rollers cooperating to ink the ductor roller, the ductor roller receives .a large and adequate supply of ink, its entire surface being practically covered With a layer of ink, of the requisite thickness and very evenlydistributed, in the short time that the ductor roller is in contact with the fountain rollers. The ductor roller being completely supplied with ink as described, comes in contact with both the cooperating ink drums and the ink is transferred thereto, and is then transferred by The first form inking roller, this being the form roller which the forms first encounter as they come around from the im pression, thus receives an adequate supply of evenly distributed ink for the first, and also for the subsequent inking of the plate. As hereinbefore described the second form inking roller is supplied preferably from the first form inking roller. Thevibrating distributing roller 81, running in contact with the first form inking iroller, assists in providing and maintaining a constant and even distribution of the'supply of fresh ink.

The first form inking roller, carrying fresher ink than the second form inking roller, and making contact with the plates on the form cylinder-ahead of the second form inkingroller, prevents the lint or dust from the paper being picked up by the inking mechanism, as would be the case if a comparatively drier and more sticky form rollershould come in contact with the plates immediately after they have leftthe impression. A very rapid and efficient speed control for the ductor roller is also efi'ected.

By reason of the ductor roller cooperating with the two fountain rollers, and being as it were pressed orwedged therebetween, the ductor roller is immediately" brought down from the high speed at which it was spinnin 'or rotating after leaving the ink drums and almost at once is brought. to the slow .speed of the fountain rollers, which would The change ofboth the ink'drums to the first form inking roller.

thermore, when the ductor roller, at the other end of its travel, engages in like manner with the two ink drums it will be practically immediately brought up from the comparatively slow speed of the ink fountain rollers to the speed of the ink drums, which likewise would not be the case if but a single ink drum were used. I

Thus there is secured a much better and more quickly acting control of the ductor roller on a high speed press, in which the inking mechanism is likewise highly speeded, than would be otherwise possible. There is also insured an adequate supply of ink for fast running presses, and this supply very fully and uniformly; distributed to the various devices. Y

Other objects and uses of the invention will be understood by those skilled in the art or may be ascertained by practice with the invention. It will be understood that changes may be made from the exact construction shown and described without departing from the principles of the invention and without sacrificing its chief advantages. v
