Application filed August 25, 1904. Serial No. 222140.

T 0 all whom it may concern:

Be it known that I, FERDINAND VON EULENFELD, gentleman, a subject of the German Emperor, residing at London, England, have invented certain new and useful Improvements in or Relating to Rotary \Veb-Printing Machinery for Simultaneous Multicolor-Printing, of which the following is a specification.

My present invention is designed for use with and for application to rotary web printing machines which are provided with what are known as fudge boxes or auxiliary printing drums or the like or other appliances of the well-known character employed in newspaper printing for printing stop press news wherein two revoluble axles are cm ployed near the paper cylinder (i. c. the impression cylinder) and stereo cylinder (i. e. the printing cylinder) one of such axles carrying the so-called auxiliary printing appliance and the other axle being ordinarily provided with any suitable surface adapted to ink said auxiliary printing appliance from the stereo; but where such rotary printing machines are not already provided with such auxiliary printing appliances (all of which I will hereinafter refer to as the auxiliary printing drum) then the latter or such-like arrangement must be provided to enable my present invention to be applied to such machines.

Description of the Drawings.

In the accompanying drawings I have illustrated two alternative ways of carrying my present invention into practice:

Figure 1 is a vertical longitudinal sectional view 01. 6. local view of arrangement with two ink ducts for applying two or more colors (in addition toand independently ofthc ordinary black ink) to a rotary printing machine of any suitable character for printing newspapers etc. Fig. 2 is a plan view thereof.. Fig. 3 is an edge view (plan) of one of the divisible side cheeks for use in carrying out my present invention. Fig. 4 is a view in elevation of said divisible cheek removed from the machine. Fig. 5 is a view showing the parts of said side chee is separated. Fig. 6 is a local plan view of one part of the second axle on which is mounted the inking surface formed in two halves i. 0. two half cylinders which are secured in position on said axle by a split collar. Fig. 7 is an end view on line 7-7, Fig. 6, looking in the direction of the arrow 2. Figs. 8 and 9 illustrate a modified arrangement namely with. only one ink duct for applying color or colors according to my present invention.

Referring to the drawings :Z represents a part of the stereo (i. a, printing) cylinder of a rotary printing machine for printing on a continuous length or web of paper; and Y represents the paper (if. c. the impression) cylinder.

A is the axle or shaft which carries the auxiliary printing device having at least one substantially uninterrupted printing surface B.

C is the second shaft or axle (which in an ordinary auxiliary printing drum carries an inking surfacc not shown-adapted to ink the type or printing surface on the auxiliary printing drum) which shaft C in this case is provided with an inking surface I) of small diameter formed of two half cylinders D D (see Fig. 7) these seiiii-cylindrical parts D D being readily mounted in position on the shaft C (without removing the latter) by means of the split hinged collar or garter E the two parts of which are at one end hinged or pivoted together at E while the other ends are secured together by the hinged fastener E pivoted at E and provided with a slot at E adapted to fit over the turn-button E which latter by means of a quarter turn thus firmly secures the fastener E see Figs. (3 and 7.

The shaft or axle A (which carries the auxiliary printing drum or device) is positively driven with the main impression cylinder in the ordinary or any suitable manner and to this shaft A there is fixed the toothed wheel No. 1 gearing with the toothed wheel No. 2 to which is attached the toothed wheel No. 3 both fixed to the inking roller I which is driven thereby and the toothed wheel 3 gears with the toothed wheel at on the second inking roller H and the toothed wheel 4 gears with the toothed wheel 5 fixed on the sec ond shaft C whereby the latter with the inking surface I) fixed thereon as aforesaid is positively caused to revolve, The sizes of said gear wheels 1, 2, 3, 4, and 5 being so proportioned as to cause exactly two revolutions of the inking rollers I) ll and .l to each revolution of the shaft A. For facility of applying these gear wheels 1, 2, 3, 4, and 5, I may znlvantageously form same (or any of them) in two or more sections and provide said sections with means for securing and lock ng each of same in position so that the whole of these gear wheels can be fixed to their respective rollers without removing any of the shafts from the machine. As the portions of these split gear wheels may be secured in position to one another in any suitable man ner, as for example after the well-known manner of securing split pulleys or. other split wheels therefore it is not necessary to further describe same here it being necessary however to always arrange said gear wheels in suchwise that same will be perfectly clear of contact with the paper and stereo cylinders Y and Z.

The divided side cheeks employed according to this invention are shown in detail in Figs. 3, 4 and 5 and comprise the two separate plates F and G; the plate F being provided with the semi-circular recess F adapted to fit round the shaft A and at the other end with a semi-circular recess F adapted to fit round the shaft C; while the cheek G is provided with a semi-circular recess G adapted also to fit round the shaft C and is further provided with slots Cr G for the axles of'the inking rollers J J K K so as to allowslight movement of the latter when acted on by the eccentrics and also the cheek G is provided with the prolonged slots G for receiv ing therein the ends or supports carrying the ink ducts J and K which latter are kept pressed forward by the springs acting thereon. It will therefore readily be seen that the side cheeks F and G can be easily placed in position on the axles A and C without removing the latter said cheeks being secured together in any suitable manner as for instance by the screw bolts f and nuts 9 and at same time the axes of the various inking rollers as well as the ink ducts are thus mounted and secured in position in and by means of said side cheeks H and I are the two inking rollers which are positively driven from the axleA as aforesaid these rollers H and I being caused to rotate exactly evenly with the inking surface on the shaft C the roller H being provided at H with longitudinal grooves or channels and also the roller I is provided with similar grooves or channels I on opposite sides thereof the position of these grooves H and I being such that they' will coincide as these rollers revolve together and also the grooves H will in turn coincide (as they revolve) with the grooves D formed in the inking surface D on the shaft C as aforesaid; thus each separate color on the separate parts of the inking surface D (on the axle C) will be separately and independently conveyed through the roller H and roller I to a separate part of the printing surface B carried on the shaft A as aforesaid.

, The ink is conveyed to and applied to the inking surface D on the shaft C as follows Two separate ink ducts J and K are .provided-each containing a different ink or color as desired. The color from the ink duct J is, by means of the rollers J and J conveyed to the inking roller J all these three rollers being idle rollers; and similarly the inking rollers K K convey the ink from the duct K to the inking roller K said rollers K K and K being also idle rollers. On the shaft C, I arrange and employ a double eccentric L M as shown in Fig. 2 it being understood that a corresponding double eccentric is arranged towards the other end of the inking surface D on the shaft C; while a disk L is fixed towards each end of the inking roller J in such position as to bear only against the eccentric or part L of said double eccentric, and similar disks M are fixed on the inking roller K said disks being arranged and adapted to bear only against the eccentric or part M of said double eccentricsaid eccentrics or parts L and M being exactly oppositely disposed on the shaft C. Thus it will readily be seen that when the eccentric or part M of the double eccentric permits the inking roller K to make contact with the inking surface D, as shown in Fig. 1, at this moment the other eccentric or part L of the double eccentric will be acting on the disks L and thereby forces back the inking roller J out of contact with the inking surface D. The said double eccentrics L M being so disposed that in this way the inking roller K will be allowed to ink one half of the inking surface while the roller J 3 will be permitted to ink the other half It will of course be obvious that the inking surface D can be divided into more than two parts and by providing a corresponding number of separate ink ducts and eccentrics thereby more than two colors can thus be applied; or if desired the color can be applied in other than a regular manner, that is to say by modifying the parts in an obvious manner one color can be supplied to a greater portion of this surface D than the other or others.

Suitable means may be employed to adjust and fix in position the aforesaid inking arrangement for example distance pieces formed of split washers or split rings :0 such as shown in Fig. 2 may be employed on the shaft C between the outside of the side cheeks F and Cr and the frame or bearings supporting said axle C, so as thus to positively hold said inking devices (supported inside said cheeks F G) in position relatively to the printing surface B on the axle A.

In Figs. 8 and 9 I have illustrated a single ink duct arrangement for applying the color from the ink duct N to said printing surface Bthis arrangement comprising a single inking roller N which when permitted to do so,

by the cut-away portion of cam C carried on the axle C, applies the color from said duct N to the inking surface D; and from the latter the color is transferred to the inking roller 0 in frictional contact therewith. P is inking roller mounted in the slot or loose bearing er J and which normally rests in the position shown in full lines in Fig. 9 that is out of contaet'with the inking roller 0 and in contact with or in position to make contact with the printing surface B said roller P being also adapted to be moved back to the position shown in dotted lines in Fig. 9 so as to make contact in this position with the inking roller 0 and for this latter purpose the shaft A is provided with an eccentric A in the path of travel of which latter there is inserted the anti-frictional roller Q pivoted at Q to the lever or device R pivoted at R to the framework-there being a similar lever R at each end of the axle P of said inking roller P, and bearing against same, so that as the eccentric A comes round it acts on the roller Q and lever B and thereby forces the inking roller P into the position shown in dotted lines where it receives its quantum of ink from the constantly revolving inking roller 0; and then, when released by the eccentric A it is automatically returned to the position shown in full lines to make contact with and ink the auxiliary printing surface B. The shaft A has fixed thereto the toothed wheel 6 which gears direct with the toothed wheel 7 fixed on the shaft C whereby the latter is constantly revolved, and in turn revolves the inking roller 0 by friction or otherwise.

It will be obvious that in addition to applying one or more colors in the aforesaid manner, I can also by dividing the ink duct J or Kor N and employing different colored ink in said divisions of the ink duets, thereby apply various colors in parallel columns or stripes i. e. side by side in addition to or in place of applying the different colors as previously described. Also it will be obvious vthat I can if desired divide the auxiliary printing drum longitudinally and apply such segments or parts to the axle or shaft A in a similar or analogous manner to that described with reference to the inking surface D on the shaft C; which printing surface B may either be fixed to and revolve with the shaft A or may be so arranged as to revolve around said shaft A in which latter event said shaft A may be rigidly fixed 'L. 0. nonrevoluble. Thus instead of black ink being supplied to the auxiliary printing drum B as heretofore-by this invention I can apply thereto any desired color or colors and thus simultaneously print in any desired color or colors in the columns of a newspaper etc. while printing other parts of said newspaper in the ordinary black at the same time.
