19 Claims.

This invention relates to multi-impression rotary printing presses, and while various features of the invention are of more general utility, the specific application thereof shown by Way of eX- ample in the accompanying drawings is t0 a multi-couple web press specifically designed for printing multi-colored labels, so-called French edge labels, which may be embossed, and which are cut from the web as by means of a die forming part of the last printing surface. At the present time such labels are commonly printed on a rubber blanket by means'of bed and platen presses at comparatively low speed. Herein I provide a high speed rotary press for 1B performing the Work embodying various features of convenience and eiiiciency as will appear to those skilled in the art by reference to the following description taken in connection with the accompanying drawings, wherein;-

Fig. 1 is a diagrammatic side elevation;

Fig. 2 is a side elevation of the press;

Fig. 3 is a fragmentary transverse section along a line corresponding to a portion 'of the pathof the web through the couples and disclosing parts in end elevation as seen from the right ofFig. 2;

' Fig. 4 is a similar View with parts in ya different position of adjustment; Y

Fig. 5 is a partial transverse section along a radial line through one of the printing couples; Fig. 6 is a'vertical section through the driving means for the impression cylinder as seen atY the right of Fig. 5 and on an enlarged scale;

Fig. 7 is a similar section on a horizontal plane with the parts in a different position;

435 Fig. 8 is an end View of the support for the im pression cylinder as seen from the left of Fig. 5

i but with parts omitted;

Fig. 9 is an enlarged side elevation of the central portion of the press;

,49 Fig. V10l is an enlarged detail of the gearing for actuating the throw-off mechanism which appears in Fig. 9;

Fig. 11 is a plan section of the same; Fig. 12 is a vertical section on line I2`I2 of Fig. 3 on an enlarged scale;

Fig. 13 is an enlarged elevation of parts shown in Fig. 12;

y Fig. 14 is a section on the line I-M of Fig.

13; and

Fig. 15 is a section on the line l5-I5 of Fig. 12. Referring now to Fig. 2, the press shown is organized on a longitudinally extending frame 20 which may be supported from the base plate 22 by Ymeans of the gussets 24.- In contrast with the 55 usual machine in which the parts areorganized between two side frames of substantially similar construction, this single frame is the primary support.V of the mechanism and as such the ma chine may be characterized as Yhaving a substantially single frame. onthe frame in overhung relation in a circular series and carriages 28 which support plate cyl- Y inders 39 and suitable inking mechanism 32 are Brackets 2t are mountedV adapted to be moved in and out along these brackets to adjustV the plate cylinders Vradially of the circle. I have deemed it unnecessary toV illustrate and describe the details of the parts carried by the .carriages as these may be of any usual or suitable construction.

Extending from the frame 2G, as perhaps best seen in Fig. 5, is a central stationary shaft 34 of a length roughly twice the width of the print-` ing mechanisms of the press. The outer end of this shaft may rest (see Figs. 2, 3 and 4) in a pedestal 3B which, as clearly seen from Fig. 2, is of restricted size so as to leave the nearer ends of the cylinders and the space within the same substantially unobstructed by frame parts. Mounted on this shaft (Figs. 3, 4 and 5) is a subfrarne 33 on which are supported, herein by means more fully to be hereinafter described and in radial planes corresponding to the planes of the plate cylinders 39, impression lcylinders fili. The sub-frame 38 (Fig. 5) may be splined to'shaft 3d by means of the key 42 and is engaged by screw M journalled in pedestal 36 and adapted to be driven through gears t by means-of a hand crank applied to hub 8. By means of this the sub-frame 38 with the impression cylinders may be withdrawn to the left in Figs. 3 and 4V .f

from the position in the former gure, in which the impression cylinders and the plate cylinders oppose each other, to the position of Fig. 4 wherein the impression cylinders areexposed at the side of the press; This renders the cylinders particularly accessible for changing or for purposes of make-ready and provides for other advantages which will appear as the description proceeds.

When the sub-frame 38 is in the position of Fig. 3 and the press in condition for running I may provide a support for the outer ends thereof, here illustrated (see Figs. 2 and 9) as consisting of three rotary lugs or latches 59 on certain of the brackets 28 adapted to be turned to enter suitable recesses 52 provided in the sub-frame, as best illustrated at the right of Fig. 9. The brackets and the sub-frame thus give one anothera mutual centralizing support and the legs 59 also maintain the sub-frame 38 in its innery position.

2 Referring to Fig. 5, the Vcylinders of the press are driven from a main drive gear 54 meshing with planet pinions 56 secured to the shafts 58 of the plate cylinders 30. These'shafts also carry-inwardly of frame 20 pinions 60 associated with bearers 6| which respectively drive pinions 52 and cooperate with bearers 63, both on shafts 64 journalled in the frame 20 and from which the impression cylinders are adapted to be driven. To permit the movement of the impression cylinders axiallyy as hereinbeiore described, their connec- (Fig. 6) working in a slot 'l2 (Fig. 12) inV clutch member 62 holds the two members 68 and 06 together whilepermitting their relative movement lengthwise of key 61. The other face of clutch member S8 is provided with a diametral slot I3 adapted to receive a key 'I4 secured to the endof shaft 'l5 of the impression cylinder.

` pin 'i3 projecting frornthe clutch member may enter a bore in the shaft, as best seen from `Eig. 7, to guide the-parts. When the sub-frame 38 with the impression cylinder on its shaft V'I6 is moved toward the left, viewing Figs. 5, 6 and 7, the shaft may move away from its fixed driving connection, as illustrated in Fig. 7, but when returned is clutched thereto so that the cylinders of the printingcouple rotate in unison in the ordinary manner. An eccentrically positioned pin 'I9 (Fig. 6) carried by one of the parts 58 and 16 and entering an opening in the other provides for the connection of these two parts in the proper 'angular position as otherwise it wouldA be possible to engage the parts in two diierent positions 180 apart. The keys and SiV have a certain freedom of ymovement in their slots providing for a slight disalignment of the parts, Ythe connection being essentially what is known as an Oldham coupling. In the operating position of the cylinders an annular bearer disc on the impression cylinder may be received in a groove 82 on a bearer disc at the inner end of the plate cylinder, maintaining the aligned positionr of the two cylinders, and this engagement may `bereleased when it is desired to withdraw the frame 30 of the` impression cylinders either by tripping the latter inwardly in the manner hereinafter described or by retracting the plate cylinders radially outward. Y

Inthe printingV processA for which the press illustrated is especially intended the printing-is effected against a rubber blanket B (Figs. 1 and 2) which is trained as an endless belt through the couples and it will be apparent that the unobstructed opening `at the fro-nt side of the press, viewing Fig- 2, due to the overhung mounting of the parts and the movable mounting of the irnpression meohanism carried by sub-frame 38 facilitates the introduction of this blanket. The blanket is of considerable length and'v is here shown as trained through the Aseveral couples and around Vvarious guide rollers not necessary to specically identify and as looped back and forth around stationary rollers 84 and rollers 85 mounted on an adjustably movable frame (Fig. 2) and over a dance roll 88. The `adjustment of the frame-carrying rollers 86 through a given dis- Ar central ofhin the present instance, slack in six times greater amount, while the dance roll keeps the` blanket taut. The pedestal 3S, as best'shown in Figs, Il and 5, may be provided withV amovable gate 89 to permit theinsertio'n ofthe endless blanket in encircling relation about shaft 34.

To provide for the positioning of the blanket with the impression mechanism withdrawn and to support it in its approximate path through the printing couples when the impression mechanism is withdrawn for any reason I may provide between the successive couples (Figs. 1, 3, 4 andr15) supports in the formof posts 90pr0jecting in overhung relation from bases 92 mounted to slide (Figs. 12 to 14') in substantially'radial ways 94 mounted at the inner side of frame 20.. The bases 92 are formed with rack teeth with which mesh pinions 95 on pinion shafts 98 projecting through the frame where they carry at the rear vside thereof pinions 00 adapted-to mesh with .a central gear |02.` For rotating gear |02 a gear |04V (Figs. 12 and 3) may be provided which has a shaft |06 (Figs. 3 and 15) projecting to the nearer side of the press where it is'provided with an actuating handle |08. Gear |04 may be turned by means of this handle and the supporting posts 90k recip- Y rocated back and forth across the lines connecting the bites of the successivev printing couples. Thus in the full line position of Fig. 2 the `blanket B` extends outwardly of these supports. They may, however, beshifted tothe dotted line position carrying the blanket with them and taking up on the dance roll 88. The impression cylinders may now be drawn inwardly and moved outward from their position within the plate cylinders and the blanket will be maintained in position ready to receive the impression mechanism again within its circuit. Also in the preliminary positioning or replacement of the blanket it may be trained over these supportsand movedy out of the way in such manner as to permit the insertion within thesame ofthe impression mechanism.` Y

The web Aof paper W (Fig. 1) passes through the printingv couplesin the usual manner. In the case of labels, as herein described, during or at the end V*of thel printing operation the,k

printed areas are died out from the sheet, leaving a web of scrap as in la sheet of cooky dough.

` In this operation the cut-out portions are pressed against and adhere to the blanket B.Y The 4main body of the web, that is, the sheet of scrap, may

Y be `diverted over the guideroll I0 to a feeding out belt l |2 and in the machine shownis chopped up along transverse lines by means of suitable cutting mechanism (not shown) carried onshaft ||4 and delivered to the rapidly running, transversely located conveyor belt ||6 (Figi 2) to be disposed of.V VThe blanket B with :the adhering cut-out portions freed from thev sheet ofrscrap continues in a different path and is bent sharply on itself about a suitable guide'edge IIB 'and serves todisengage the' labels Ytherefrom sol that they drop to table |20 withwhich isfassociated a feeding out belt |22, all mountedona verti'-` cally adjustable Vframe |24. (Fig. 2) adapted to be raised or lowered by the hand wheel |26, this mechanism providing for the delivery of the produ ct of the machine. -f

I will now describe the mechanism for tripping .theirnpression cylinders, referring more particularly to Figs, 5, 8 and 9.l The yokes |28 in which the boxes |30 in which the shafts 'I6 of the impression cylinders are journalled and in which they areV retained by the 'latches |32 movein ing with segment gears |48 formed on shaft 2,084,281 isuitable radial openings in the'sub-frame 28 and. printing@cylinders or tobe positioned outwardlyy are secured by a dovetailed connection |34 (Fig. 8). to an underlying support comprising an upper portion |36 and a lower portion |38 (Fig. 8),

'themselves connected by a .dovetailed connection which, as best shown in Fig. 5, extends in ak plane at an angle to the axial line of the cylinder. An adjusting screw |45 provides for longitudinally vmoving member |36 and thus provides for a fixed radial adjustment of the impression cylinder. The major or throw-off movement of the cylinder is effected by moving the. support consisting of the two parts .|36 and |38 bodily in and out to carry with it the yoke |30( For this purpose the part |38 has pivoted at either end thereof links |42, the inner ends of which are connected vto discs |44 mounted for rotation within the subframe and provided (see Figs. and 1l) with gear teeth |46 along a segment thereof cooperatwhich carries gear |52 operated through a suit- "able gear train from handle |54; Handle |54jmay be provided with suitable latching Vmeans to permit it to be maintained in one Vor another -position on .oppositesides of the pins |56 projecting from' locking disc |58 mounted on the side of the sub-frame 38.v It will be apparent, referring to Fig. 9, that if the handle |54 is moved to the right in Vthat figure, the'disc |44 will rotate counterclockwise, the outer ends of the links |42 will be drawn inwardly and the various impression cylinders 40 will be simultaneously and equally drawn radially inward to separate the same from the plate cylinders. The range 'of movement is indicated in Fig. 10 by the opening Iil in disc |46 which provides for the passage vof screw 44. Y

I am aware that the invention may be em- VYbodied in other specific forms without departing from the spirit or essential attributes thereof, Y

and I therefore desire the present embodiment to :be considered in all respects asillustrative and not restrictive; reference being had-to the appended claims rather than to the foregoing description to indicate the scope of the invention..
