Myinventioii is a drive and control for printing presses. l f

My vpresent invention relates to a drive and control for printing presses both for sheet delivery and rewinding into rolls after the printing operation.

My invention is illustrated as applied to a quadruple press, tltiat isa press consisting of fourprinting units,tivo of these constituting the upper deckvan'd tivo the lower deck of the press; rhe press is designed with i'evvindingmechanism for each of the decks. -t frequently happens in rewinding when botli'decks are in operation, that one ofthe reivinding rolls Willheconie Wound to its full size before the other. In this case it is desir'- aele vto remove the fully Wound roll and to start Winding another roll in its place.

` An object therefore-of my invention'is to accomplish this, by shutting down the 4deck which is inoperat'i-on or Winding, in other words to shutdoivn the deck' which has its roll fully Wound and to still leavethe other Y deck inoperation. My invention therefore Acoin-prises a Idual control forthe. upper'and lower decks Aby which bothof these decks may be operated at the saine tiine or either` one inav bel-stopped and the other one continue in operation. f l

My invention applies to improvements in operating dou-ble deck quadruple presses having printing and rei-Winding and priiilt and uc iinchanges to completely shut doivnthe print* ing press land such changes With inypiinprovenient-s may be inade in a ininimuin aniount of tiine. The inventionY to loe claimed Ypertains f delivery Ythe sprocket chain connection may be disconnected. i

l Another object of iny inventionV is in the simultaneous control of the *opening orletting in of the clutch and applying brakes to bring the press tov` a quick stop and to effect' aquickrelease for startingof the press.

fr still further object of niy invention is in connection with the clutch control having operatino` devices such as levers positioned at vopposite sides of the press and distributed l longitudinallv'thereof to actua-te long shafts on the opposite sidesfofthe press. In this,

connection a detail 'feature of iny improvef nient is in utilizing longitudinal shafts which are given a longitudinal `inovenient hy the operating ylevers in counter-distinction to a rotary inoveinent to operate the inain clutch.

By this procedure there is no lost motion on` l account of a torque or the like of the shaft.

Fig. 18 is a partial elevation of the centra-1 gearing of Fig. 1, showing a. different manner of driving the upper deck.

Referring first to Figs. 1 and 2. the main frame of the press is designated by the numeral 11, in which the upper printing deck is designated generally by the numeral 12 and the lower printing deck by the numeral 13. These decks have separate printingr units designated 14, 15, 16 and 17. The printing units are more or less standard in construction, the gear connections however, being changed to be suitable tor my invention.' The main frame structure of the press has a central frame designated 18 in Fig. 2, in

which the central drive gears and shafts are mounted in a main panel 18.

A stand designated generally by the numeral 19 is mounted on one side of the central frame 18, being illustrated in side elevation in Fig. 3 andpartly in plan in Fig. This stand encloses the inain drive pulley 20 which is mounted on the outside of a lower' main clutch 21, this clutch being mounted on the shafting designated at 22, journaled in the stand 19 and in the main panel 18. (Note Figs. 4 and 9.) The particular construction employed is .not part o" my immediateinvention and is not set iorth in detail. T he features have to do mainly with the connections and operation of the clutch.

.ai main fly wheel 23 is connected to the shaiit to rotate therewith when the clutch is engaged. A lower pinion 24.- is connected to the sha'lt 22 and is always in mesh with a. main drive gear which is journaled on the panel 18. This gear is always in mesh with gears 26 which dri e the lower deck ot' the press actuating the printing units 16 and 17.

ne manner ot driving the upper deck is indicated in Fig. 1. The gears 27 which are on movable axes are shown in mesh with the main gear 25. .These gears are constantly in mesh with the two gears 27 of they upper printing units 14 and 15 of the upper deck. Therefore by this arrangement the upper and li'uver decks are driven through the medium ol the main` clutch 21, the shaft 22, the pinion and the main gear 25.

As an alternative drive for the upper decl-z, the gears `27 may be shifted out of mesh with the main gear in the manner to be descrihcd hereunder in detail and shifted into driving connection with a seconilary driving gear 28 mounted on a fixed axis and support ed in the panel 1S. Such shifted position is indicated in Fig. 18. The drive for the gear 28 is by means of an upper pinion 21) on a shaft 3() which is journalcd in the panel 1S and in the stand 19 (note Fig. f1). There is a spreader 31 mounted between the shafts 22 and 30. T his spreader carriesl a sprocket tightening idler arm 32 having an idler sprocket 38 thereon which engages the sprocket chain 34, this chain taking over a lower sprocket 35 connected to one'elenient oi the clutch 21 and such element being always driven by the pulley 20 and another sprocket 36 connected to an element of the upper clutch 37. This upper clutch 37 when one element is driven through the sprocket 36. is designed to connect the shaft 30 in such drive. The shaft 30 carries a Hy wheel 38.

By this construction when the gears 27 are shifted to their upper position in mesh with the gear 28, the drive, to the lower deck remains through the shaft- 22, the pinion 24, the gear 25 and gears 26, but the drive to the upper deck is through the sprocket S5, the upper clutch 37, the shai't 30, upper pinion 29,gear 28 and Y.gears 27, thereby driving the upper. units. This therefore. drives both decks frein the main drive. If it' :is desired to stop the upper deck7 theupper `clutrh 37 delivery and forsheet delivery operations. it is desirable ,to slackenthe sprocket idler may be thrown out `and the sprocket chain WillcontinueI rotating the clutch element connected to the sprocket gear 3G, but tne shaft will remain atrest. Or alternatively the lower clutch 21 may be disconnected from the lower shaft 22,.thereby1stopping the pinion 24 and the; main gear 25, bringing the lower deck to rest and tne upper deck being driven 'through lthe sprocket chain and theupper clutch 37 connected to drive. the upper shaft '30. These lalternative drives are-the type used forvprinting and rewinding. The first lowered position is for print-ing andsheet '33 and disconnect the sprocket chain `from the sprocket Wheels and 36, allowing such chain. `to rest on the spreader 31 as shown by y `rIhe manner of shifting the gears 27 is [substantially as follows,V` having reference particularly-to Figs. i6, 7 and-8z The upper part of the central frame 18 is provided with slots 39. Connected on opposite sides of these slots 39, there are a pair of adjustable-segmental rings 40. These have a thru-bolt 40 connectionyallowing accurate adjustment. The studs 41 carrying they gearsv 27y which are rotatably mounted Vhave suitable bushings 42 (note Fig. 7) and have Aa central hub portion 43 fitting' freely in the slots 39,'and on the inner side there is a vcircular head44 which engages the frame on surroundingportions ofr the slot 39 and fits in the inner surface of the segmental rings 40. On the outside there is a sleeve 45-on the stud 41 having a circular Vshoulder:portion 46 `Which'lits against the outsideof the rame on vsurrounding portion 'of Vthe slots 39 and lin the outer Vsegmental ring 40. This sleeve maybe jammed tight by means of a nut 47 on the'screW threaded -end 48 of `thestud 41. v

y In order to disengage the teeth of the gears 27 from they teeth of the gear 25 or r28, it is necessary to be able to slide the gears .27'. mounted longitudinallyon the stud 41 which is accomplished by sliding the pin 49 in an angular feathervvay 49, the pin being connectedto `a collar 50. In the normal rotation of the gears thepin is held in the cirfitv in a substantially vertical opening 53 in the top of the frame (-see' Fig57). "screws are held in adjusted position jby collars 54v and 55, there being handwheelsi56 on `the top of each screw and these screws pass through the'slot 57 in the frame structure surroundoffer a posit-ive stop limit When the. circular heads ofthe stud 41 and the circular shoulder portion 46 of the clamp.- l

ing sleeve 45 are shifted through the medium of the shifting screws 51. rIhe heads 54 and shoulders 46 seat themselves against the inner surface of the segmental rings 40. When the-studs 41 are so shifted then the gears 25 Ymay be slid into. mesh yWith either the gear 25 or the gear 28, the circular heads 44 forming positive `'stops and therefore accurately centering the studs 41.

The immediate mechanism for shifting the clutches and operating the bralres acting on f the fly Wheels is substantially as follows, havinfrreference particularly to Figs. 3, 4 and 5. Such mechanism is substantially the saine for the upper and lower clutches and therefore only one Will be described A clutch rockery shaftf() is journaled in suitable lugs on Vthe outer portion vof, the stand 19 and carries a clutch operating arm 61 on Vcach side of movaole elementwith .a slot 62 therein in which there is a slidable bloclr63'engaging the clutch collar 64 by Y meansV of a clutch pin 65,` thereby shifting the movable element of the clutch. An arm 66 is secured tothe rocker shaft 60 by a set scren7 67 and has a linlr 68 connected thereto. In regard to the upperclutcln this link is shown as of a fixed length, Whereas in regard to the lower clutch it is indicated as ad-V justable, being. designated 68.- rllhe links 68 and 68 are each pivotally connected to up` perand lower similar levers 69and 69Qwhich latter are each made of a pair .of straps 70, and midway of the length of each lever there is a pivotally connected long leven' suchlevers being designated 71 and 71.

'A brake rocker shaft 72'is journaled insuitable bosses on the stand 19 and carries a brake actuatingrarin 73 in which the inner end is pivotally connected to the double lever 69. This actuating arm T3 operates between the rtwo straps 70. which form the double lever 69. The shaft 72 `has a brake carrying hub 73v whichY carries the brake lshoe 74` connected theretoy byl apin and slot connection 7 5. A depending bell crank end '76 forms part of the lever 7 3 and is adapt-cd `to Contact. with an adjusting'screw mounted on y a box`r 7 8 'on the standv 19. '-lhe lever VT3 is pivotally. connected to the straps of the lever 69 asindicated 'by the pivot 7 9. y'rlhe manner of operation 4of the elutchesfis substantially as follows: i

In Fig. 5 the clutch shifting mechanism is indicated with the clutch thrown in and with thefbrake free. To open the clutch and apply the brake, a downward movement of the link 71 causes a combined movement of the double lever 69r operating on the pivot 79 and the lever 73 being on the pivot 72. This gives an upward movement of the brake shoe 74, this bearing against the periphery of the fly wheel. Such action brings the lever 73 to rest so that the double lever 69 can move `as if on a fixed pivot 79. The further downward movement of the double lever 69 through the medium of either the link 68 or 68 gives a downward motion yto the arm 66 rocking the shaft G0 and shifting the arm 61 to move the clutch collar 64 and hence the the same manner.

movable element of the clutch to open the clutch. As above mentioned both' the main lower clutch and the upper clutch operate in Then it is desired to throw in the clutch and release the brake, an opposite or upward movement is given to the link 71 which causes a. combined upward movement of the double lever 69 and the lever 73. The lever 73 pivots as above mentioned on r72 until the bell crank end 76 contacts with the adjusting screw 77. Such action withdraws the brakeshoe from the periphery of the fly wheel and in preventing furthermovement of the lever 73, causes the double link to move as if on the fixed pivot 79, thereby giving an upward thrust on the `links 68 and 68 and hence shifting the clutch collar from the open to the closed clutch posi tion.

The manual control of the lower or main clutch is substantially as follows:

The hand lever located in front of the stand 19 is mounted on a rock shaft 81. This rock shaft has a segmental gear 82 projecting from one side which meshes with a segmental gear 83 on the longitudinal shaft 84 extending across the stand 19 from oneY side to the other. This shaft has an arm 85 which is pivotally connected to the lower end of the link 71. (Note Figs. 3, 4 and The manner of operation of the upper clutch is effected by a handlever 86 which is connected to a. rock shaft 87 extending transversely of the stand 19. This rock shaft carries :i segmental gear 88 which meshes kwitha segmental gear 89 on a double arm 90 pivoted on the stud 91. This double arm 90 is connected to the long link designated 71l of the upper clutch. f

The apparatus for controlling the main lower clutch from opposite sides of the printin pressand at different points along these si es utilizes apair of longitudinal rods 92, these being positioned adjacent the base of the machine and slidable in guides 93. Positionedalong the sides of the press there are a series of hand levers 94 mounted on pivots 95 secured to fixed brackets 96. These levers ferent sections of the rod 92. This coupling is shown as having the slot tapered on one side as indicated at 101 (note particularly Figs. 1, 2 and 13, through 17). Therefore by the action of rocking the hand levers 94 in a direction longitudinal of the press, the

rods 92 may be given a longitudinal sliding motion. I find it satisfactory to use round steel tubing for lightness; these also having sufficient stiffness to prevent any bending.

In order to transmit the motion from the rod 92 on the side remote from the main clutch, that is on the side remote from the stand 19 and also from the side having the stand, the shaft 81 is conducted through a journal 102, on the frame 11 and 103 on the opposite side of the press. On the side having the stand 19 there is a hub 104 clamped to theshaft 81 and this has a depending arm 105 which carries rollers similar to the rollers 98 operating in a vertical slot in a coupling similar to the coupling 100 shown in detail in Figs. 15 and 16. Therefore when an of the hand levers 94 on the side of the mac ine having the stand are operated they shift the.

rod 92 and hence transmit a rocking motion tothe shaft 81, thereby actuating the main clutch and the brake for the main shaft.

At the side yof the machine opposite the stand 19 there is a hand lever 106 which has a hub 107 directly connected to the rock shaft 81. Therefore by operating this hand lever thefshaft 81 may be oscillated and the main clutch operated. A downward extension 108 from the hub 107 has rollers similar to the rollers 99 operating in a slot similar to the slot 101 and in the coupling .100 and thus when any of the hand levers 94 distributed lengthwise of the printing press on the side opposite the stand is actuated it gives a rocking movement to the cross shaft 81, hence operating the main clutch.

The upper clutch may be operated from one osition on each side of the press and this is Ve ected by conducting the rock shaft 87 through journals 109 and 110 in the main frame of the press and mounting of hand levers 86 and 111 on the opposite ends of the shaft 87. Therefore when such shaft is rocked by the levers 111 and 86, it operates the upper clutch and the upper brake.

v A drive motion is carried from the gear 25 through a large bevel gear 112 meshing with a bevel pinion 113 carried by a longitudinal shaft 114 which has a bevel gear 115 meshing with a bevel gear 116 on the gear 117 meshing with the gear 118. These latter gears are utilized to drive the cutting and delivery section of printing press.

In order to selectively lubricate the bearings of either the upper or lower clutches,

These Y loo llU

lilo

I utilize the construction illustrated in Figs. 9 to 12 which may be considered asoperating in connection with Vthe shaft 22,..` 'I he shafthas a longitudinal bore 119 which'has a reciprocal grease tube 120 mounted' therein.

surface of the shaft.-v rvIhe outer end of theY grease tubev 120 has a coupling 127 mounted thereon, preferably being screw. threaded.

Y This coupling has a iange 128 with grooves 1293 in its periphery? which` lgrooves are engaged by studs130 screwed into the endofthe shaftr and through a cap disc131, thiscap disc being illustrated as fitting over the hub 132 of oneqof the fly wheels. By fthisconstruction the coupling 127 is forced to rotate with the shaft `and hence the grease tubealso rotates withthe shaft and cannot rotate relatively thereto. The; sleeve 131` mounted on the cap 131 is to protect the operators from havingV their wclothing caught in the rotating grease` cup. t

A grease cup133 is secured` tothe end of the coupling 127 and by pulling out on the greasey cup the coupling ymay be slid outwardly through the space131 between the cap disc 131 and `,end of kfly wheel hub thereby pulling the grease tubefi120 and shifting the port 135 to aregister with greaseyduct 121V and the Vport 136 outl of register withl grease duct 12,2.

In this positionrgrease maybe forced into the outer clutch bearing nearest the stand 19. In

a similar manner, when the greasevcupY is pushed upon to its 4innermost position as` shown in Fi 51.19,' the grease port 136 will come to register with-grease duct 122 and the-,port 135 will come out ofregister with duct 121 and make it possible to force grease into the i remote bearing of clutch.

The bleeder duct 126 serves as an escape for any grease that may collect between end rof the tube 120 wheny pulled out rand end of bore 119 which would hamper getting tube `120 back to its inner position.
