IN KING MECHANISM.

Application filed March 12, 1920. Serial No. 365,354.

T 0 all whom it 121a,;2 concern,

Be it known that we, JosnrH J. VALSER and HARLAND FANKBONER, citizens of the United States, residing, respectively, at Ann Arbor, Mich, and in Chicago, in the county of Cook and State of Illinois, have invented certain new and useful Improvements in Inking Mechanism, of which the following is a specification.

The invention relates to printing presses and more particularly to the inking mechanism and cooperating parts, the invention being directed and especially adapted in its chief aspects or features to inking mechanism fitted and adapted for fast rotary presses, such as are used for newspaper work and some magazine work.

Objects and advantages of the inventlon will be set forth in part hereinafter, and in part will be obvious herefrom, or may be learned by practice with the invention; the same being realized and attained through the instrument-alities and combinations pointed. out in the appended claims.

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

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

Of the drawings Fig. 1 is a fragmentary side elevation. partly diagrammatic, of the inking mechanism and a rotary printing couple of a printing press embodying the invention;

Fig. 2 is a fragmentary end elevation. with parts in section, looking at Fig. 1 from the right;

Fig. 3 is a detail with the parts separated of the adjustable cam for controlling the.

ductor roller;

F ig. at is a fragmentary elevation of certain parts shown also in Fig. 1. and illustrating the relation and co-action of the ductor roller. ink drum and its governing cam;

Figs. 5 and G are diagrammatic views illustrating the peripheral travel of the ductor roller upon the periphery of the ink drums, or fountain roller or both and Fig. 7 is an enlarged fragmentary sectional View of the ductor roller mounting, taken on line 7-7 of Fig. l, the same parts being shown in section in Fig. 2.

Referring now in detail to the embodi-- ment illustrated by way of example in the accompanying drawings, a rotary printing couple is represented having a form cylinder 1 with its shaft 2 running in bearings 8, and a cooperating impression cylinder 4 with its shaft 5 running in bearings 6. The web 03 runs through between the cylinders in the usual manner, andis printed upon by the plates upon the form cylinder 1.

In accordance with certain features of the invention, a ductor roller or like ink conveying device is provided which travels along the periphery of the fountain roller, or of the ink drum, or of both, the quantity and duration of the conveyance or transfer of the ink from one of said members to the other being governed and controlled by the extent of such peripheral travel of the ductor roller along the other of said mem bers rather than by a dwell or pause of the ductor roller in contact with the fountain roller, or the ink drum, or both. In conjunction and cooperation with the foregoing, the invention provides, but is not limited to, a continuously traveling ductor roller, and preferably to such a ductor roller. traveling in one direction in a circular path. a The manner of ink conveyance or transfer hereinbefore described, renders possible also the employment of a continuously rotating fountain roller, and in accordance with certain features of the invention a fountain roller so operating is provided, although it will be understood that in its broader aspects the invention is not so limited.

In accordance with certain features of the invention, the ductor roller is resiliently impelled toward the ink drum, the fountain roller, or both of them, and thereby is adapted and capacitated to effect and describe its travel along the periphery of either or both of said other members. In conjunction therewith settable or adjustable means are provided for moving or restraining the ductor roller against the resiliently impelling means tg limit or vary or govern the extent of such peripheral travel of the ductor roller, and thereby control the quantity and condition of the ink conveyance or supply to the plates upon the form cylinder 1.

More in detail, a ductor roller swings about a center and is resiliently impelled outwardly radially so as to have the desired travel along the periphery of the ink drum, fountain roller, or both, and settable devices, such as an adjustable cam or cams press the roller back, more or less, to limit and control the extent of its peripheral travel along the other member or members. The more the ductor roller is hell back the less the extent of its travel along the periphcry of the ink drum or fountain roller, and the less quantity of ink is transferred to the members or parts of the inking mechanism which convey the ink to the plates upon the form cylinder 1.

In the embodied form. these various features of the invention, while capable of separate and independent use, are associated together in a single mechanism and in cooperation one with another, and together with other features of the invention not heretofore mentioned but which will be later described and pointed out.

Referring to the details of the illustrated embodiment, an ink fountain 10 is provided having therein a fountain roller 11, which in accordance with one feature of the invention is preferably continuously rotated. The fountain roller 11 is rotated in the proper direction and at varied or regulated speed in any suitable manner, as by gearing of the usual type (not shown).

As embodied herein, and in accordance with certain features of the invention, the ductor roller travels in an endless circular path, cooperating with the fountain roller at one point in its path to receive the desired or prescribed quantity; of ink, and at another point in its path depositing the ink in the desired. or prescribed quantity upon the ink drum or other agency which properly distributes it and forwards it in conjunction with cooperating devices to the printing plates upon the form cylinder.

In the embodied structure. a shaft 12 is mounted in the machine, and is preferably continuously rotated by suitable gearing (not shown) or other desired or approved means. In the present embodied form, a plurality of ductor rollers rotate about the shaft 12, thus making possible the employment of slower traveling ductor rollers and thereby securing better inking results. As embodied, the shaft 12 has fixed thereto four pairs of arms 13 1 1, 15, and 16, the ductor rollers 17, 18, 19 and 20 being mounted, respectively, in the outer ends of the various pairs of arms.

In the embodied form of resilient m0unting for the ductor rollers, each arm of the pairs of arms 13, let, 15 and 16, is provided near its external end, that is the end away from shaft 12, with a closed bearing aperture 21. In each of the bearing apertures 21 is mounted a journal box 22, longitudinally or radially slida-ble in the aperture. In each journal box 22 is journaled the shaft or pintle 23 of one of the ductor rollers, the roller with its shaft 23 being free to rotate in the journal boxes 22. The em-' bodied form of the resilient impelling means, operating preferably outwardly radially, as already described, comprises coiled springs 21 in compression between the re spcetii'e journal boxes 22 and the inner end of the corresponding aperture 21.

In the embodied form of means for moving or prc-determinately positioning the ductor rollers with respect to the ink drum, the fountain roller, or both, already referred to, the shafts preferably project out wardly beyond the respective arms 18, 14, 1:"; and 16. Fixed to the shafts 23 either at one or both ends, are cam rollers 27 and 28, which cooperate in the present embodied form with adjustable cams. The cam or ams with the rollers 27 and 28 work against the springs 24%, to radially vary and determine the position of the ductor rollers to govern the extent of their peripheral travel upon the ink drum or fountain roller, or both, to control the supply of ink to the print-in o plates on thepress. This permits the travel of the ductor roller along the periphery of the other rollers, while limiting' the extent of such travel as desired.

The embodied form of the cam control just referred to comprises an arcuate cam 29 located between the fountain roller 11 and an ink drum 30. The cam 29 is preferably multi-part, the parts being circumferentia-lly adjustable or positionable with respect to each other.

A detail of the embodied form of the cam is shown in Fig. 3, the two circumferentially adjustable parts 31 and 32 being provided with adjusting slots, one slot being in the part 31. another slot 34- being in the part 32, and the two parts having common registering slots where the parts 31 and 32 overlap. The various slots are provided with suitable clamping bolts 36, 37 and 38 threaded into some part of the machine frame. Thus by this cam the point of departure of the ductor roller from the fountain roller and its point of incidence upon the ink drum may be independently and nicely determined and regulated.

The arms 13, 1.4, 15 and 16 and their repart of the ductor rollers would describe such an are or circle as is-indicated byline in Fig. 4, andthe extreme outer part of the roller 27 would describe such apath as is indicated by the line 41in Fig. 4. I

Due to this position of the path of the ductor rollers and totheir resilient impulsionradiallyoutwardly by the springs 24,

theyare' capacitated to travel or roll along.

the peripherywof the ink drum 30 and the fountain roller 11, the springs 24 compressing and then extenclingduring thls curvilinear travel' of the ductor rollers. The circumferential and relatively independent adjustment of the parts 31 and 32 of the cam roller from the fountain roller 11 can be ex- F1 actly governed, thereby giving a nice and accurate control of the quantity of ink taken. The circumferential adjustment of the part 31' of cam 29 toward or from the'ink drum 30de'termines the point in the travel of the ductor rollers atwhich they will come into contact with the periphery ofthe ink drum,

and thereby an equally nice and accurate control is obtained of the delivery of the ink from the ductor rollers to the ink drum.

The continuous and unidirectional travel taining the high speed of ink supply through the inking mechanism as a whole to meet the demands of high speed presses thus maintaining a high quality of printing. The ductor rollers are also'adapted to take the speed ,of the fountain rollers when receiving ink and to take the speed of the ink drum when delivering the ink. The cam rollers 27 are so proportioned that the ductor rollers'a-re brought to the speed of the ink drum when they come into contact therewith.

In the present embodiment of the invention means are also provided for governing the ductor roller as it approaches the f0untain roller and to control the point of its incidence therewith at the'beginning of its travel about the periphery thereof, to assist or participate in the control of the ink supply as already described.

In the embodied form thereof, a cam 43,

also approximately of arcuate form is provided along the path of approach of'the ductor rollers to'the fountain roller (at theright in Fig. l). The cam 43 is likewise circumferentially adjustable, and'for the purpose is provided with slots 44 and clamplng bolts 45. The lead'end 46 of the cam 43 is inclined outwardly, so asto receive the cam rollers 28in their extreme outward position radially in the corresponding pair of arms.

Roller 27 is of such size that as it rolls along cam 29 the ductor roller is brought to the surface or peripheral speed of the ink drum 30, and roller 28 is of suchsize that as it rolls along cam 43 the ductor roller is brought to the surface or peripheral speed of the fountain roller 11.

The ink drum 30 may representaany desired element ormember in the inking system adapted to receive the ink from the duc-' tor rollers, and to participate in its distribution, its forwarding and its supply to the printing plates on the form cylinder, the 7 remaining parts of the inking mechanism being shown more or less conventionally.1

The ink drum 30 cooperates with aform inking roller 46, which supplies ink to the plates upon the form cylinder 1, and likewise to another ink drum 47,'which ink drum also supplies ink to a form roller 48, the form roller 48 inking the plates upon the formcylinder 1. Cooperating with form roller 46 is a smooth metal roller 49, running fri'ctionally in contact with the-form roller, and assisting in the distribution of the ink on the form roller. It will be understood that the form and number of these various members or elements of the inking mechanism may be varied without affecting the principles or scope of the invention.

Suitable vibrating mechanism is provided for vibrating certainxor all of the members described, and as embodied the ink drums 30 and47 and the roller 49, in the preferred form, are all vibrated, and the ink drums 30 and 47 are likewise positively driven, while the roller 49 is frictionally driven from form roller 46. In the embodied form of vibratingmeans, there is fixed on a shaft an eccentric 56, the strap 57 thereof being connected to a rod 58. The rod 58 is pivotally connected to an arm 59, which arm is fixed to a shaft 60 journaled in a bracket '61 mounted upon the machine frame.

Fixed to' the shaft 60 is an arm 71, provided with a roller 72, which-roller runs in an annularly grooved collar 73, formed upon the shaft 74 of roller 49.

Fixed also to shaft 60 is a geared'sector 75', andintermeshing therewith is a geared sector 7 6. fixed on a shaft 77, which shaft is journaled in a bracket 78, mounted upon the machine frame. Fixed to shaft 77 is an arm 62, having at its other end a roller 63, whichroller runs in an annular groove in a collar 64, which is fixed to the shaft 65 of the ink drum 30. Fixed also to shaft 77 is an arm 67, said arm carrying at its free end a roller 68. Roller 68 runs in a grooved collar 69 on the shaft 7 of the ink drum 47. Thus as the shaft 55 rotates, through the mechanism just described, ink drums and 47 and roller 49 are longitudinally vibrated in addition to their rotary movement.

The general operation of the mechanism will be clear from all the foregoing. It will be noted in Fig. l that the circular path to, or toward, which the ductor roller is resiliently impelled is indicated as 40. The

intersections of are with the periphery of ink drum 30 will measure the maximum travel of the ductorroller along the periphcry of the ink drum. This travel involves a concurrent backward radial movement of p the ductor roller against its resilient mountv are 40, except that this is modified by the position of cam 29.

The circular path or are 10 of cam roller 28 corresponds as to its conditions to those already described for the arcurate path 40. Path 41 is that which roller 27 would follow were it not acted upon by cam 29. If cam 29 did not act on roller 28, the ductor roller 17 would follow upon ink drum 30 the full path indicated in Fig. a. By moving cam 29 in a circumferential direction toward or from the ink drum, the point of incidence of the ductor roller therewith to begin its peripheral travel therealong can be varied, that is shortened or lengthened. This corresponds in a general way to the variation in the dwell of the usual ductor roller upon the ink drunnbut possessing the advantages herein enumerated together with other advantages. The foregoing will be clear from the diagrams of Figs. 5 and 6, in which the center of the ductor roller may be regarded as traversing the are a from the instant it leaves cam 29 and engages the ink drum. During its engagement with the ink drum, the ductor roller center travels along are I), and as it leaves the ink drum it again follows are H.

The action at the fountain roller is substantially the same as will be understood without extended further explanation. With the concurrent use of cams 43 and 29 there is, of course, not only a movement on to the ink fountain roller from one cam but also a lifting off movement on to the other cam. One or the other of said cams at the fountain roller may be dispensed with if found desirable.

The invention in its broader aspects is not limited to the specific mechanisms shown and described but departures may be made therefrom within the scope of the accompanying claims Without departing from the principles of the invention and without sacrificing its chief advantages.
