The present invention relates to improvements in intaglio: presses ofI the type adjustable for printing'from cylinders oi'diierent diameters.

An object of my invention is to provide a` 5y printingpress' in which the printing point is maintained constant andthe printing cylinder bearings are correspondingly. adjustable `fo-r cylinders .of different diameters. Obviously,` the fountain bowl must also be shifted for printing cylindersof different sizes butfother changesv of parts, including the `troublesome adjustments of compensators. heretofore necessary, yare avoided.

Another object of my invention is to provide.y

a housing for the printing cylinderand yfountain picked upgby the web, is prevented.

Other objects and advantagesof my invention will appear in the followingv `description of a preferred embodiment and thereafter the novelty and vscope of the invention will be pointed out in the claims.A

In the accompanying drawings-z i Figure 1 is a View in end elevation of a` printing couple embodying my invention, the parts being adjusted fora large size printing cylindery'y Fig. 2 is a front elevation of the couple lookingl from the right hand side of Fig. 1, `with certain parts shown in'section; t Fig. 3 is a .view in section taken'substantially on the line 3 3 of Fig'. 2 but showing the parts adjusted for a small size printing cylinder;`

Fig. 4 is. aview in section taken on lined-4 ofFigZand` A Y y Fig. 5 is a fragmental `endview 4showing one of the vertically adjustable blocks which 'provide bearings for the journal vboxes of the print' ing cylinders. r The printing unit illustrated in the A,drawings is adjustable forprinting cylinders of two sizes, o one being just twice the diameter of the other. It will be understood that a printing press may comprise a number of such units or couples disposed in tandem. v

yThe printing unit comprises ay base I to which This is .of importance when printing at- `slide blocks 26 highlyvvolatile ink on the cylinder before itis are bolted a pair .of side frames II. -Attlfleir PTENT. om@

upperends'y theframesv II are ybolted to beams.v I3,v which connect the unit illustratedy to other units'and otherparts vof thepress.v The web W enters the; printing unit or 'couple from a precedingk printing cou-ple ,or directly from av paper ,roll, passing rst about a water lcylinder I5 which -is adapted to cool the web if it has compensator roll-IB and overa bar IY'I and enters between la rubber facedimpression cylinder I8 and a printing cylinder 2.or`20A, as the case may be. 1- From the printing cylinder. the printed f web passesabout a bending roll 22 and-over av steam y'druml2v3. f Thence it is guided byvsuitable means (not shown) to the next .coupleof the press orhdirectly to the folder.

The cylinder I8 is pressed against the printingcylinder by apressure ro1l.,2li.r The impression cylinder `I8 is journaled in blocks 2'I whichv been heated by the steam drum of a preceding f :printing unit. The web-then passes about a" have limited vertical ysliding movement in the Toprevent overheating when running` at high, speed, the pressure-'roll may be water cooled', and,.to this end, provision is madeA t i 25 for circulating water through the rollbyway of pipes'28 'which `pass through stuffing boxes,

29. It will be understood that the vwater ,cyl inder I5 -is similarly cooled, being providedwith water pipe `connections `which .pass through suitable stufng boxes. f

The pressurejroll 24 and impression cylinder I8v arev friction driven by the printing cylinder 20, and provision is made for adjusting the blocksv 26 s oas to vary the 'pressure'of the cylinder t IB on theprinting cylinderand `also to raise the impression .cylinder `clear ofthe printing cylinder, when changing yprinting cylindersor .when` threading` the web through the couple. To `this i end screws 32 are `provided whichfrise from the top ofthe slide blocks 26 respectively. Each-,

screw 32: is threaded through a nut 33 pivoted to one end of an arm 34. Each arm'34 is pivoted,

Vas at 35, to.v the adjacent side frame I I vand is held more or less rigid.byl the'pressure of ,av heavy spr-ing at the yoppositaen'd thereof. The l screws .32.)` are attachedl to theslide blocks 2li is provided at one end with .ahand wheel- 4I,

whereby it may be manually operated to turn the screws r32.. .v j y' lencloses said worm and worm gear.

A power means is also provided for turning shaft 40 when desired. Rotatably mounted on shaft 40 is a worm gear 43 which meshes with a Worm 44 xed on a shaft 45. The latter is journaled in a housing 46 which is pivoted on the shaft 40 rand A plate 30 outside this housing is integrally connected to the worm gear 43 and is formed with `an annular series of holes 3|a', any one of which may be engaged by a spring seated lock pin 3| in the hand wheel 4|. By this means the worm gear 43v maybe locked to the hand wheel and hence to shaft 40. from thehousing 48 and isprovided at its outer end with a pivot slot 49 to receive a stud 50 projecting from the-adjacent press frame I. A rel versible motor 5| is mounted on this bracket and a suitable coupling 52 connects the motor shaft to the worm shaft 45. The motor bracket pivots' `on the` stud 50 as the shaft 40 is raised or lowered by adjustment 'of the screwsy 32. g

The shaft 49 may be turned manually When th pin` 3| is disengaged from plate 30 `or may be turned bythe motor 5| when the pin engages 'any of the holes 3Ia. Rotation of the shaft in one direction will turnfthe screws 32 in such direction as'to raise the slide blocks 26 and with them the pressure roll 24 and impression cylinder. I8. Turning of the shaft in .theopposite direction will lower the impression cylinder and `cause `the pressure roll to bear against'the printing cylinder. Further rotation .of the shaft in lowering direction will result in applying pressure of the springs 38 on the pressurey roll which.; in turn, will press the impression cylinder I8 against the printing cylinder 20.

The printing `cylinder turns in lcylinder boxes 58 which rest in bored recesses 51 formed inslide blocks 58 disposed respectively `at lopposite ends of `the cylinder.

` The blocks 58 are mounted to slide in suitable ways 59- formed in the press frame I I. .Each block is raised and lowered by a screw 60 threaded into a nut 6| carried by the block. Each screw has a worm gear 62 fixed thereto. The worm: gears are enga-ged by worms 63 fixed upon a shaft 64. The latter is provided at one end with a hand wheel 65, so that by turning this hand wheel `the screws 60 will be rotated y and the blocks 58 will be raised or lowered as the case may be.Vv The framesA II,` are provided with sockets 66 to receive the nuts'l when the blocks 58 are lowered.

In Fig. 1, I show a large printing cylinder 20 mountedl in operating, position, and in Fig. 3, a small printing cylinder 20A inv printing position. The printing point which is the line of contact ofthe web with the top ofthe printing cylinder,

`remains xed, and consequently the blocks 58 must'be loweredf to mount the' cylinder 20 and must be raised to mount the cylinder 20A. When the blocks 58 are lowered to the position shown in Fig. 1 they may be locked against the side frames I I by bolts 53 which are screwed into tapped holes 6,1 in the blocks, but when the blocks are raised to mountV the smallcylinder 20A the bolts 53 are f threaded into other tapped holes 68 in said blocks. When the blocks are in raised position theyproject so far out of the ways 59 that the bolts may not suffice to hold them firmly in place, and hence I provide a clampingjaw'i) oneach side frame II, as shown in Fig. 5.` This jaw enters a recess 10 formed at the top of the adjacent block 58 and 4by tightening up aiboltf1| the top of the block is firmly clamped to the press frame. l

The printing cylinders are inked by dipping into A motor bracket 48 (Fig. l) projects a fountain bowl 12 and obviously this bowl must be raised for a small cylinder 20A, and lowered yarms 15 are secured tovertical bars 18 which are provided adjacent their upper ends with teeth 11, as shown in Fig. 3.l These teeth are engaged by pinions 18 fixed upon a shaft 19 extending from end to end of the couple and journaled in the sideframes |I. At oneend of the shaft 19 a worm gear is xed, as shown in Fig. 1, and this gear is engaged by a worm 8| on a worm shaft 82 which is provided with a hand wheel 83. By operating this hand wheel the arms 15 willlbe raised and lowered, as desired, to adjust the position of the fountain bowl.

As shown particularly in Fig. 3, a doctor blade is mounted close to the printing point and by comparing the position of the doctor blade in Fig. 3 with that in Fig. 1 it will be observed that a very slight adjustment is required to adapt the blade for rdifferent sizes of cylinders. It will also be notecl that the angular distance between the printing point and the point of contact of the doctor blade with the printingcylinder is comparatively small, so that thereis little opportunity for the ink on the cylinder to dryl before it is picked up by theweb W.

The doctor Yblade 85 is clamped in a holder 86 whichis pivoted upon a slide block 81 `adapted to slide on a rail 88 extending from end to end of the couple. In order to provide for the adjust- V ment from the' position shown in Fig. 1` to that Ashown in Fig. 3, or, vice versa, `the rail 88 is slidably fitted to blocks 89 Whichare fixed to the press frame II. While the rail is" slidable laterally on said blocks, it is prevented from moving endwise by a central vbracket 95 fastened to the bottom of the rail, as shown in Fig.`- 3. bracket is slotted lengthwise to receive a shoulder screw |00 threaded into a `brace |0I connecting the opposite press frames I I. The adjustment of the doctor blade is effected by operating a crank 90 at each end of the couple. Each crank 90 is fixed. upon a screw 9| which passes through a poppet 92 fixed to the adjacent frame II and which is maintained against endwise displacement by collars 93 fixed on the screw and bearing against oppositel faces of the poppet 92. Each screw is threaded through a pop-pet 94 fixed upon rail 88 so that by turning the crankv 90 the rail 88 is adjusted laterally toward or from-the printing point. The slide block 81 is reciprocated on the rail lbymeans which will be describedhereinafter. Pressure of the doctor blade 85 on the t printing cylinder is maintained in the usual manner,. by a weight 96 attached to a chain 91 that passes over a sheave 98 and is fastened to an arm 9 9 fixed to the holder 86. v

A housing |02 encloses the printing cylinder and the fountain bowl, as shown to best advantage in Fig. 3. This housing is provided at the front with a pairof doors |03 and |04 which are hinged vrespectively at the top and bottom of the housing. In order to permit of changing printing cylinders, the side wall of the vhousing |02 isl formed with openings |05 extending inwardly from the front of the housing, and each opening is normally closed by a slidingdoor |06. Each doorv is formed with a double lip |01 at the top and bottom to receive, respectively, the upper and lower edges 0f the opening |05. At its inner end each opening is formed with a pair of halfroun'd cutouts |08 and`v |09 respectively, to clear fro through a drain pipe H8. Referring now to Figs. 2 and 4, it will be seenl the' printing cylinder shafts. When the4 large printing cylinder 26 is mountedin the couple, as

couple, a projecting cover platev H'| is provided.

on each of the doors |66. llVhen the smaller printing cylinder 20A is mounted in place, as shown in Fig. 3, the shaft of this cylinder passes through 'the upper cutouts |68. The sliding doors |66 are then inverted so that thecutouts H6 will register withcutouts |08 to fit about said shaft, and the cover plates IH will-then close the openings |69.`

The housing |02 which rises above the printing point has an opening at the top to admit the web W and the pressure roll i8, as well as the doctor blade and operating mechanism therefor. However, there is a baiile plate H2 depending kfrom the rail 88 and another baffle plate H3 xed to the doctor blade holder 86 which in large measure shield the printing cylinder from exposure to a drying atmosphere. These bafes serve .to catch the inkthat is scraped from the printing cylinder by the doctor blade and any ink spray that may be thrown oif centrifugally fromthe printing cylinder, and cause such ink to flowy back into the fountain bowl. The fountain bowl is supplied with ink through an inlet H which may be suitably connected by a flexible pipeto a pump. Surplus ink overflows the rolled edge I6 at the rear of the' fountain and drops to thebottom of the housing |02. Thence it passes out that the printing cylinder is driven by a main shaft |r which extends lengthwise of the press and is journalled in suitable bearings |2| sup' ported on pedestals |22. The shaft passes through a gear box |23 and has a worm |24 fixed thereon `within said box. This worm drives two worm gears |25vand |26. The wormgear |25 isjust half the diameter of the worm gear |26, vand consequently the shaft |21 to which the Worm gear |25 is fixed, will be driven at twice the speed of the shaft '|26 to which the worm gear |26 is secured.` As will be explainedlater the shaft |21 is arranged to drive the smaller printing cylinder 2BA, While the shaft |28 drives the larger printing cylinder 20 at half the rotational speed of cylinder 26A, but the surface speed of these cylinders will be the same.`

Fixed upon the shaft |21 is a Worm |30 which drives a worm wheel |3|`. The latter is mounted on a shaft |32 (Fig. 4) which projects from the housing `|23 andv has at its outer extremity a crank |34. This crank is connected yby a link |35 to a pin |36 connecting the lower ends of a pair of bell crank levers |31 mounted on a shaft |38. The upper ends of these leversare connected by a pin |39 which forms a bearing for a link |40' that is connected to the doctor blade slide block 81. By lthis means said block is reciprocated causing a corresponding reciprocationr of the doctor blade attached thereto. The link |40 is slidable on'the pin |39 to provide for variations in adjustment of. the rail 88.`

The shaft |21 is suitably supported in journals in the housing |23l and .projects .throughl the housing on the press side, i. e., the left side, as viewed in Fig. 2. Fixed upon this projecting part of the shaft is a transversely slotted hub |42.

[which engage slots formed in a split clutch member |49 clamped upon the adjacent end of the for cylinders of diife'rent sizes will be now 'illustrated kby reviewing the steps necessaryl to re- |62 are then swung openin which position i The shaft |28 is operatively connected by gears |43and |44 of equal diameter to a shaft |45 vwhich projects from the press side of the housing |23 and has a slotted hub |46 fixed thereon. Hubs |42 and |46 are of the same dimensions and 5 each is adapted for engagement with a dog |41. In Fig.`2, this dog is bolted to the hub |46 with a i` transverse' rib thereonseated in the slot of said hub. The dog |41 is forked, having lugs M8 printing cylinder shaft. Thus, a driving con-A nection is provided for the large cylinder' 26. When the smallercylinder 20A is used the clutch member |49 is secured to the shaft of said cylinder and the forked ldog |41 is fastenedv to the hub |42. Since the gearing is such that the peripheral speed ofthe two printing cylinders will be the same there will be noc-hange in speed of the webyW` and other friction driven parts.

To provide for axial adjustment of the cylinders a bracket |58 is secured to the block 56 on the end remote from the driving gear;I This bracket carries a nut |5| through which a feed screw-|52 may be screwed byoperating a hand wheel |53 on the outerend ofthe screw. rThe screw |52 has aswivel connection toA a fitting l 55 which isbolted on the adjacent end of `the printing cylinder-shaft. The swivel connection permits the -screw |52 to turn freely but prevents 30 axial movement of the screw with respect to the fitting |55. By thismeans the printing' cylinder may be adjusted axially, as necessary, to obtain a proper printing register. i 1

The steam drum 23 is mounted in suitable bearings |66 formed in brackets`|6| mounted on the overhead beams i3. The drum is fitted with a steam inlet` pipe |62 and an outlet pipe |63, and these pipes pass through suitable stuiiing boxes, as indicated at |64.- The steam drumv is posi-` do tively driven by the impression cylinder 24;. To this end a sprocket wheel |66 is fixed upon the shaft of the pressure roll, and af sprocket chain |61 provides a driving connection between sprocket wheel |66 and a sprocket wheel |68 fixed upon a'shaft |69. The latter has a pinion |16 fixed thereto which meshes with a gear l1! fixed upon the steam drum. 23. The sprocket chain |61 is passed about a pair of ridlersi 12 and The operation of adjusting'the printing couple place the printing cylinder 26 with the printing cylinder 26A. It will be understood that the sequence of these steps may be varied. doctor blade is first raised by depressing the arm and is held in this position by of a latch- |15. The pressure rollblocks 26 raised by turningV the shaft 46 manually, or by means of the motor 5|. so' as to relieve pressure on cylinder 2Q. The tting |55 is unclarnped from one end of the cylinder shaft and the coupling mais unclarnped from the'opposite end shaft. The doors |03 and |613 of the ho are held by springs |16 and |11 respectively. 70y saidsprings are c-arriedpast dead center. The

sliding doors it are drawn out of their positions `in the side walls ofthe housing'and the cyiinder ,213 thenmay be removed through thefrcnt of the housing. Preferably, the fountain bowl 12 is removed from its supports before the cylinder is withdrawn. The dog |47 may now be unfastened from the lower hub [46 and secured to the upper hub M2. The slide blocks 58 may then be raised to` their proper position by operating hand wheel 65 and be secured by means of the bolts 53 and clamps 63, afterwhich the smaller cylinder Amay be mounted in place with its` journal boxes supported in said slide blocks.

The fountain bowl support` is then raised byv operating the hand Wheel 83 and the fountain bowl is placed in position on its supports. The sliding doors it are now inverted and reintroduced to close the openings m5 with the cover plates Hl in position to close the lower cutouts W9 in the side Walls of the housing. The doors |63 and H34 may thenbe closed. The' fitting H55 may now be clamped upon the shaft of the other, but my invention is not limited to such relative sizes cf cylinders. Thus, while I have described a preferred embodiment of my invention, it will be understood that this is to be taken as illustrative and not limitative, and that I reserve the right to make Various changes in form, construction, and arrangement of parts, without departing from the spirit and scope of my invention as set forth in the following claims.
