Be it known that I, FERDINAND IV. Hnmrrrnnn, a citizen of the United States, residing at Chicago, in the county of Cook and State of Illinois, have invented `certain .new and useful Improvements in Printing Presses; and I do hereby declare the following to be a full, clear,y and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use thc same.

This invention relates to an improvement in printing presses, and lis inirticularly conce1-ned with the provision of improved means for supplying different colored` inks to the type forni of the press.

Generally stated, it is the object of the invention to utilize the axial reciprocations of a vibrator roller not only to evenly distribute inksy of different colors over the roller or rollers posterior tov it with respect to the flow ot ink through the press, but also to utilize such reciprocations tor applying the inks to the said pbsterior roller or rollers in such fashion that spaces between adjacent colorsk are minimized or practically eliminated without danger of the colors becoming mixed. l

The invention also contemplates a novel roller construction hereinafter described in detail. This improved construction is preferably incorporated in the vibrator, but is not necessarily limited to such use. Other features, objects and advantages will hereinafter appear.

In the accompanying drawings illustrating the invention: n

Figure 1 is a vertical section passing transversely through the inking rollers of a bed and platen printing press and indicat ing diagrammatically theinking mechanism, torni, platen and paper.

Figure 2 is a diagrammatic development ot the several inking rollers, the form and the printed' stock, all arranged to illustrate most clearly the method by which the several colored inks from a divided fountain are brought closely together on the printed stock. *Figure 3 is a side elevation of the vibrator roller of this invention, illustrating the sleeve sections all `brought together to torni a plain surface vibrator.l

F i gure E is a view similar to Figure 5, but

showing the sleeve sectionsrearranged withy gaps between certain of the sections, and a smallerlsplit section inserted `lo compensate for the gaps, this" being the arrangement `ot the sectional vibrator for the' setupf illustrated in Figure 2.

Figuref 5 is an enlarged longitudinal. section of the vibrator, as shown in Figure 1-,

Figure 6 is a transverse section of the vibrator taken on the line 6 6 of Fig-nre I1.

Figure 7 is a view which may YbeY considered as a: partial continuation of `Figure 5, and which shows the relation of the split sleeve section to adjacent sleeves.

Figure 8 is a side elevationv of an iinprojvejd divider as appliedV to the fountain roller 'for the purpose of separating inks ot' dilieient colors. Y

Figure 9 is a top plan view oi' the divider, as illustrated in Figure 8.

Figure 10 is a vertical section taken on the line 10-10 of Figure 9. Y

Figure 11 is a sectional view on the line 1.1,--11 of Figure 9.

Throughout the several views similar characters of reference will refer to silnilar parts.

I have chosen: to illustrate my invention as applied to aV bed and platen press, and, for the sake of clarity, I have included in the drawings only those elements oi the' press to which itrwill be necessary to refer, and have indicated thesevr elements for the most part diagrammatically.

Referring to Figures 1 and 2, from the ink fountain 10 the ink 11 is fed onto the steel fountain roller 12, the amount of iced being regulated in the usual manner. The fountain roller 12 is given a slow intermittent rotation through the ratchet 1i. Between thefountain roller 12 and the steel idling'- roller 15, reciprocates'th'e ink transmitting or duck composition roller 1G, whichV is swung arcuately about stationary pivot 1'7 by means of an eccentric 18 in one arm of the bell crank 19. From the steel roller 15 the ink travels ontoL the idling composition roller 20 which is anterior to and contacts the steel vibrating roller 2l, to whichr rotation is imparted through an end gear 22r (Figure 3). Posterior to the vibrator 21 is a pair of angle rollers or idling composition rollers 23, which contact both the vibrator 21 and the large ini:-

ing cylinder or roller rlhe ink is taken from the inlnng cylinder 2i by a pair ot form rollers 25 which t* tape dispensers 'lor sealing pachaL ls. Blelerring again to the drawings, the guinmed stock 30 is ted trom the supply roll 3l across the platen 32 and thence (Fig. 2) under the sha-tt 33 carrying knives by vhich the paper is cut into a plurality of narrowv tapes lt is to be understood, oit course, that the platen 32, Jfollowing the inlting oi. the forni by the orm rollers 25, is swung upwardly about its pivot by the usual means (not shovfn) to print a length ot aaper, following which another length olf paper is ted across the platen.

Referring noiv to the construction of the vibrator of my invention (Figures 23 to 7. inclusive), it will be seen that. vfh the external conformation et the roller is substantially that ot the vibrating rollers commercially in use, the vibrator roller here illustrated is not turned trom solid shaY but is composed of a` shaft 3G constituting a core having at its ends reduced portions 37 slidably journaled within the bearings 38. rlhe extreme ends of the core 36 are provided respectively with the gear and with a spool 39. The roller is vibrated by the .fibrating mechanism l0 acting` through the spool. :le plurality of sleeve sections ll are slipped onto the core 3G, one end of each sleeve being shouldered as at l27 While the opposite end of each sleeve is provided with a counter bor` tor reception of the shouldered portion or an adjacent sleeve in such a manner that7 when adjacent sleeves are pushed together, they join, leaving only an annular hair line upon the outer surface or" the roller. Each sleeve section .is provided With a key-Way le, whereby the sleeves are feathered upon a` liey 45 oit the core 36. Each leev-e may be selectively clamped longitudinally on the core 36 by means of a small set sere-W Llli in the reduced portion 42.

t will be seen that because the vibrator sections 4l may be made to lit closely to- ``ffhen the press is to be adapted Por Werl; wherein dill'crent colors are to be printed simultaneously, such as the blue, black, green and orange indicated in Figure 2, the vibrator rolle' is divided into tour corresponding portions which are separat d by gaps si (Figure This is accomplished by loosening` the set srevfs flG, the sleeve sections being slipped longitudinally of the core aft proper positions. 'llo facilitate the ready sliding ol these sleeves il and to eliminate the necessity of removing the roller to slip shorter sections onto the core to compensate for the ividth ol*l the several gaps 457, l .uralte one of the sleeves in tivo parts, as indicated at 413. its shoivn in Figure 7, the

icl

split sleo'e -s snouldereffl at both ence, torining reduced portions T' e full sections on one side ot this split sleeve are i reversed from those on the other side, so that the ends of the tvfo adjacent full sections havingthe counter bores 43 slip over the reduced portions l2 and hold the tivo halves of the split ring firmly together. No

set screws need be provided on the split ring.

To reposition the sleeves. the tull sleeves i. .a t.

one side ot the split rin;rr are slid longitudinally suiliciently to allow the counter bores to disengage the shoulders ott' the split ring and allow the ready removal ot the latter. rllhe veral sleeves are then positioned as shoun in Figure 4.-, and so retained by tightening their set screvvs. The original split ring cannot be replaced because the introduction oit the gaps #i7 no longer leaves sulicient room. but a shorter split ring indicated at il-S is inserted and held in the same manner as the longer split section. ln practical use it is not necessary that each set screw be tightened7 but omy the terminal set screws in the sections betiveen which there is no l conteniplate that several split rings ot' different length he provided troni which the operator may select the l h most suitable lor the. required spa et the sections. lt is obvious also that shorter lengths of sections may easily be employed. and that the shorter the sections are, the more accurately the roller may be divided for each color ot inl.

The division ol the vibra* roller as shown in Figure el, is indicatedin Figure 2, but Yfor the salte olf clearnessv the length ot the roller has been proportie ately torcsh rtened, and only the gaps li indicated,

the lines indicating abutting sections being omitted. The inl; fountain has been di! vided with the ink di viders l-S), and the spaced colors ot inl' are ted onto the composition roller 20, which lies anterior to the vibrator. The space between adjacent iults is thus the width ot the separator 9.

LAM

il@ and grouped together in their Llo When the right-'hand edge 50 of the gap on the vibrator between' the blue and the black irll moves front its dotted line position, where the edge 50 has been well fed withy bfack ink fromv the composition roller 20, to the fu'lil line position, the angle rollers 23 are' fed with black init u J to the line 51. At the full line position o the roller, the opposite or left-hand ed'geO oi the gap is well snppiieil withl blue ink, and conversely, when the vibrator reciprocates to .its dotted line position, the edge" 50 will lead the blue in'k up toI the line 5i and a space of of an inch-or less, if necessa:r5'f-iom the black ink, Similarly, the black and `green inks and the green and orange inlrs are brought to hair line contacts by the vibrator. Having been delrvered by the vibrator to the' composition rollers 25? posterii'wr to the vibrator, th'e ink is .ted in this saine hair line spaced relation* onto the halting cylinder 24, the form rollers Q5 and the form 27, from which it is transferred to the paper in a" well-known manner.

Where the nature of the printing to be done is such that the green printing, for instante, extends to the margin of a strip 52 and the orange" printing extends to the margini of an adjacent strip 53, it is necessary that the green and the orange inls be brought onto the type form with sub stantialfy no space between thenr In those cases where the n'ature of the printing such thatl 1.8 oit an inch or so may be left between the two colors, the corres bonding ga in the vibrating roller may be made a little wider in order to prevent danger oit' any overlapping of colors due to inaccurate adjustments or to slight side play in any of the rollers. y

Figures 8 to 11 inclusive illustrate an embodiment et' an improved ink divider adapted to" be applied to the printing press, as used in accordance `with this invention. The same comprises a partition 49 having' a semi-circular -ace adapted to correspond with the fare of the fountain roller 12. An integral projection 62 is also provided on the partition 49, and is adapted to extend around the edge ot' the ink fountain 10 to which the device is clamped by means ot a screw-threaded member 61. In order that the partition may closely cooperate with anal lit tightly against the ink fountain roller 12, the end of the same is comprised of a plurality of members having their faces tormed in a semi-circle, as illustrated, each of which is faced with a lining of cork T2, or other similar or slightly compressible material. Projections 73 are provided in the faces to prevent slippage of the lining 72.

Portions of this cork lining are mounted on the two ends of a U-shaped block G3, forming part of the main partition member l), and another portion of Vhe lining` is placed upon an adjustable bloeit G8 slidably mounted within the two arms o'i the U-*shlaped block (3?).

Proper adjustment oi the slida-bie bl ci; member (i8 is obtained by means of screw threaded inembfrs (ist, rotatably iitted into the U-shaped block 63, each having: one end extending outwardly beyond the ed of the ink fountain 10, and provided with a head in" the shape out a winged nut.y These bolts 64j are rotatably `fitted in the body ot the bloeit member GS, and are fixe-d' therein by mrc-ins ol nuts or the' like 6G, as best illi trated inFigilre l0. The' liiiing or taciv p, on the' adjustable block G8 is designated the reference nun'ieral (S9,- and extei'nls slightly ab ve the linings 'T2 on the fixed members.

Pivotally mounted' on the mah-i partition member '19 a lever T0, havingr its upper end free and ad ptcd to be acted on by the end of an adjustingl screw 71,- similar to the screws 64. The lower end ot the lever TO is adapted to cooperate with aK block F5 eis tending longitudinally alongv the outer edge of the inlf:V fountain 10, and fixed thereto by means of screws or theA like It will be apparent that tightening the screw 'Ti will act throruch the lever 7() to'liorce theV parti tion t9 lorwzrrdly againstthe roller 12. In

this manner ai triple adjustment is secured which positively prevents any mixing of the different inks. i

The' resilientfacing o'li corl or the like, shown at 69 andl 72, are therefore adapted to be adljustably fitted against the ink distributin'g,r roller 1L', and' the double. or Ulshaped construction of the i'iia'in linnn;V support 63 positively prevents any mixii'i'got the inks, as even should some slight portion ofthe in'l; .l'low between the face of one of tlie'linings GQ and the ink roller, it not be innnediateiy mixed with inl;- the other side, which mih'it Flow thi-inurl' but would nece "y be/detainezil by th adji'istable retaiin h' means of). The 'triple lining herein illustrate`` absolutely prever "s any possibility of mining of the different colored inks, and constitutes one or *he important improvements in this apparatus.

As previously stated, one of the features ot my invention is that it may be adapted to a printing press already in use without the addition, alteration or modification of any of the parts save the vibrating roller. I have found, however, that in practice, after printing machines have been run for sometime, some slight longitudinal play develops in the rollers, and it is sometimes advisable in work where hair line contactbetween the Colors will be required to overcome this end play, especially in the rollers posterior to the vibrator, by a resetting of the bearings or the introduction of thin n'ashers. The sectional vib ating roller may easily be cleansed and the sleeve sections quickly reset tor other Work, without the necessity ot removing the roller trom the iframe of the machine.

lt will be readily perceived by those skilled in the designing,l ot' printing presses that the principles ot this invention are by no means contined in their applic-ation to a printing press oi the type which has been selected tor the purposes ot this speeiiication, but that it is readily adaptable to either one or tivo eolor presses, to rotary cylinder presses, and that it malies no inherent diil'erence in the application of my invention Whether the ink is delivered trom the vibrating roller to the printing` type through the agency only ot rollers, or of an inliing plate, or ot' other suitable means.

dany departures eould be made trom the speciiie constructions, and arrangements here shown Wit-hout departing,`r` from the spirit and scope ot my invention.
