PAPER-WEB-CONNECTING MECHANTSM FOR PRINTING PRESSES.

Application filed June 25, 1926. Serial No. 118,437.

Our invention relates to improvements in means for connecting rolls of paper webbing in printing presses.

Themain object of the invention is to press while the old roll is still operating, and i to start rotation of the fresh roll by the running web before uniting the new web with the old, then effecting theunion of the two webs while they are in motionand finally cutting the web of the exhausting roll, and

Another object of the invention is to provi de means for substituting new rolls of paper for old rolls on printing presses having a plurality of decks without stopping the operation of the press.

\Vith theseand other objects in view the invention is illustrated in the accompanying drawings, wherein,-- V

Fig. 12 illustrates the cutter frame and tripping devices as viewed from above and on the line 12*12 of Fig. 11.

Fig. 13 shows a vertical elevation of the devices disclosed in Fig. 11 but viewed from the line13'13 of Fig. 11.

Fig. 14 illustrates in side elevation, the movable brake and core-roll aligner which operates on the end of the core-roll after thelatter has been elevated to make room for the fresh roll, and Fig. 15 shows the hand wheel adjustment 00 for the aligner in top view.

. Referring to the drawings, and particularly Figs. 12--3 and 11 thereof the numeral 20 designates a vertical end bar of the press frame at a feed-end of the press, said bar frequently carrying a plurality of horizontally-extending arms 21.

These arms 21, are arranged in pairs, one pair being located in adifl'erent horizontal plane from each of the other pairs, and each pair of arms being utilized to sustain paper rolls for a certain deck in the press.

In the present instance (Fig. 1) the press is presumed to have three decks, and while this is not essential to the invention, there are certain structural features of the inven tion which are designed to cooperate with devices for any one of the plurality of decks.

Each arm 21 is provided at its inner side with a plurality of bracket plates 22, which no latter extend horizontally therefrom". and

these bracket-plates sustain inverted T- shaped rails 23,the brackets having vertical i slots. 24;.throu1gh': which boltsz25', extend; freely and then screw into the rails sorthat said rails may have a horizontal sliding movement onthe=- braelrets ina directiorr ing recesses 28 that areprovidedin theupper. edges :oflthe arms 21.

'At the outer ends each. roll-supporting arm..2l, is. provided with a pivoted tongue extension .291'2LI1Cl to .each of-r'these pivotedlexztensions, there is pivoted one end. of a lever 30? while the z opposite end; of. each lever. 31, is pivotally attachedto a swinging bar. 31. These swinging-bars 31 have-one end pivoted tothe. outer. side of the arms 21 while the depending. end of. each swinging-bar has a. slot-.32 therein;

A (p late 33 is seoured to the-under side .of the raili23, .andeach plate is provided .With a pin. or. stem '34, which projeetshorizon tally. therefrom and x extends through; the slottedend of-"the swinging lever- 31..

By meansaof the lever. 30, lever. 31- and pins v34,- the. slide rails 723 are eausedto' be retractedor. moved; inwardly-1 ati. the inner sides of the arms E21. as. the tongnes 29-. are swung up; n

The PUIPOSGOfIiZhlSECODStIfUOtlOIllSlZO permit both the tongue-extensions and the :rails to *be. retracted and moved: inwardly at the side of: the. arms to get. them out-of the way while fresh rolls of paper. areibeing elevated past. lower to upper. decks.

By reference to Figs. 2-:3-4.and lLof the. drawings,- it will? be: noted. that each track-rail 23 is prov-idediwith a-carriaige 35 andithat ea-eh carriage" ismounted on rollers which -.st-ra:dd1e'the center web of; the T-rail androllonsaidrail. 1

It willifurther be noted that each carriage has a; bearing bloek 36 thereonwhieh latter has a normal position slightly aboveithe' up per horizontal edge of the rollsupporting arms beoause these bearingrbloeks. are provided. to support. the ends of. the. spindles which carry, the fresher full .rollsand these rolls are. to.v be advanced to. the. operating position. by the carriages without rotating them as they advance untiltheyare dumped into: the bearing,recesses- 28. This feature willpresently be morefully explained:

Each carriage is-conneoted by anioperating cable 37 which cables are lead around guide pulleys 3'8 andalso around pulleys39 thatv are. carried by a head" 40. on the outer end of a horizontalpiston-rod'41,the piston rod'ihaving a head 42 that is movazble by fluid pressure in a. cylinder 43, which in this instance, is located at the base of the press between; the." two. vertical; bars; 20. of. the frame, as can be seen in Figs. 1 and 2 of the drawings. 7

It is believed to be obvious that when the piston 42, is made to travel in one direction in'the cylinder"43, the cables will be drawn andthe carriages 35, onwhich the spindles carryingthe' fresh paperrolls are sustained, willb'e moved or advanceddovwirdthe nor. mal bearing recesses 28 atthe inner end-sot the arms 21-; V The fiuid pressure to and from tlicey'linder 4391s conducted through a pipe 44;. which is controlled by a three-way valve 45"; as indicated in Fig. 2', ofthe drawing.

By'reference to Fig. Qofthe drawing, ,it will be notedthat the fresh. roll of paper 46" is rnounted on a spindle 47 andthati the spindle. is seated in. the bearing-blocks 36 on the carriagesfifi.

It will; also be noted that one end spindle..47carries.a grooved wheel 48, which may be termed the: normal brake-wheel, while the opposite end of said spindle carries another grooved wheel 49 and also: a collar 50-having a pin'51 projecting there- 'fl Omaii v V This. latter. grooved wheel 49 andthejcoh 12-1 50 with itsfpin 5.11 are novel features with us.a nd "perform-useful fiinctions as willv presently. be more. fully explained,

Obviously,.a fresh roll' of paper; cannot be advanced and placed, in the bearings where the. spindle. offthe exhaustingrroll is looated..without first displacing theexhausting roll' and as our mechanisms. operate without; stopping the web of the exhausting roll, .it1is apparent thatthe exhausting roll or core as we oallitl must be moved. while still unwinding. to. make room. for the. placing; of. thefresh roll in the. normal bearings:2'8.,

Thev ll'leCllfilIllSlILfOI. displacing the opere ating exhaustingroll will therefore now. be explained, reference being made particulars ly to Figs.. 1.3.5..6r8 and f. the drawings.

Itl isof course to beunde-rstood that in Fig. 1, themeclianism isviewed from. one

above. the I uppermost. pair of. deckrarms.

These vertical raolbbars are guidedat intervals between theirh113per andrlower ends by. suitable cross guide-bars 53. v

The upper ends of'these vertical rackbars 52are connected'to the lower ends of opposite sides of the press be moved in unison.

'We have therefore, in this instance, provided rack-teeth 58 on these bars 52 and we connect the rack on the bar at one side of the press with a pinion 59, and engage this pinion with a gear on one end of a hori zontal cross-shaft 61, which latter extends across the press and has another gear 60 and pinion 59 which engages the rack at that side.

Thus the racks 58, pin ons 59, gears 60 and shaft 61 merely serve to connect the rackbar 52 at one side of the press with. the other rack-bar at the opposite side of the press to insure a like vertical movement to both rack-bars.

No matter whether the bars 52 be rackbars or not, they extend vertically at opposite sides of the press and move vertically together and pass the inner ends of the several pairs of deck-arms 21.

lVe provide this vertical movement of the bars 52, for the purpose of effecting the displacement of any one of an exhausting paper roll or core roll from the normal bearings 28 of any one of the decks without stopping the revolution of that core-roll and to make room for the new roll before we connect the new web with the "exhaiiisting web, and we effect this operation by means of a novel arrangement of core-lifting arms which the vertical'bars actuate, as will now be explained.

By reference more particularly to Figs. 8 and 9 of the drawings, although the mechanism is also disclosed in. Figs. 1 and 3, it will be noted that each vertical bar 52 is provided in this instance, with a plurality of swinging or lift-bars 62.

These lift-bars are spaced vertically on the vertical bars so as to provide a pair of lift-bars for each deck,one lift-bar being on the vertical bar at one side of the press and the other l'1ft-har being on the vertical bar at the opposite side of the press, and both being arranged in the same horizontal plane, because one is to engage one end of the core-roll spindle that is to be displaced while the other lift-bar is to engage the opposite end of the same spindle.

Each lift-bar 62, has its lower end 63,

pivotally attached to the vertical bar 52 and near its upper end each lift-bar has an inclined bearing-slot 64, with a laterally extending prong 65, at the entrance and under side of said slot.

Each lift-bar 62 has a latch device 66 which is designed to normally hold said bar in the vertical position at the side of and to the vertical bar 52, as in Fig. 9 of the drawings, and a spring plate 67 attached to the vertical bar 52, constantly presses against the lift-bar and will press'the upper end of the lift-bar laterally to the position shown in F ig. 8, when the latch 66 is released.

The upper end of each lift-bar 62 is connected by a link 68 to one end of a lever 69 while the other end of said lever is pivotally secured to a stationary bracket plate 70 at the side of'the vertical framebar 20,

therefore when the lift-bar 62 is unlatched, its upper end will swing laterally to the position shown in broken lines in Fig. 8,

which position presents the prong beneath the bearing 28 and. the spindle 47 of the coreroll 46. This takes place before there is any upward movement imparted to the ver tical. bars 52.

Vhen the fresh roll 46 is mounted on the carriages 35, it is so placed thereon that the free end edge 71 of the web will have position at the upper left hand quarter of the roll circumference as viewed in Figs. 3 and 11 and this edge is provided with an application of glue 72.

\Vhen the fresh roll is placed on the carriages and the circumferential position of the end edge 71 properly located, the collar 50 onthe end of the spindle 47 of the same roll is set so the pin 51 will project radially on a line at the rear of the edge 71 of the roll so that as the carriage moves the fresh roll forward the free edge 71. of the web will be located to the rear of the vertical center while the pin 51 will be at the rear of that free edge.

By again referring to Fig. 1 of the drawing, it will be noted that at the side of the vertical bar 20 of the press frame, there a head 73 having a brake bar strap 74 at each end thereof and a. brake shoe 75, is attached to each bar-strap.

This structure is not new with us and forms no part of our invention, but the purpose of these brake devices is to fit about the ground wheel 48 on one end of the spindle .1-7 while the latter is seated in the normal bearings 28 and simply clamp the wheel sufiiciently to prevent the running roll from gathering momentum and feeding the web too fast.

This brake mechanism is disconnected from the grooved wheel 48 when the running roll is becoming exhausted, and in its stead we apply at the opposite end of the spindle an improvedibrake device which we havedesrgned to move upwardly with the core roll as the. latter. is displaced; to. make room for the fresh roll.

a -ha'ndiwheel 78 by means of which the rod may be rotated. On this threaded rod we mount a. head 79. (see Fig. 15) which head has a scrcw-tl'ireadcd bore through which the rod screws.

()l'iviously,.by turning the hand wheel 78 and'rod 'i'i', the head 79 may be moved hori- V zontally on the red the distance of a few inches-fora purpose that will presently be explained.

Two guide bars 80,.are' attached to the head 7 9 andthese bars are outer ends by a cross hcad S1.

Onthe'rOdsSO we mount a carriage 82 so the lattermay travel freely on the rodsbetween'the heads 79 and'Sl, and this carriage pivotally sustains two brakQ-straps'SS-E while a suitable coupling 84' is provided to connect the straps.- v

The carriage82 may be adjusted in a verticalplane by turning the hand. wheel 78 and-causing the head 79 to move horiZontally onthe rod 77, and as said head 79 may readily be turned on the rod77, the latter,

with the carriage 82 thereon maybe swung down to present the brake-straps 83, in ver tical: alinement with the grooved wheel 49 on the spindle of the roll that is turning in the bearings 28 prior to the elevation and displacement of that running roll as its web is becoming exhausted in order to'make Kill room' for. the fresh roll whose web is to be united with the exhausting and elevated running roll.

It should be understood that this latter brake device is designed to be engaged with thcgroovedrwheel 49 and then the brake device 7 3-7 4 on the opposite end of the same spindle may be disconnected from the grooved wheel 48, so that as the exhausting running roll is transferred from the bearings 28 and movcd upwardly to the position 85=in Fig; 11' ofithe drawings, the'traveling a'nd'movable' brake 83, may swing up with the exhausting roll and'lnaintain the proper tension thereon.

\Ve have found in practice that during the shifting of the running core roll-from the lower to the upper position, the web may not be delivered accurately to the press and to meet this and maintain proper alinement', we provide the screwrod 77 and the threaded bore in the head 79 so that the enconnected at their (Fig.2) and when the-inner inclined endi 26 of'the rack-rails23 are reached, the carriages tilt and dump the roll and spindle therefroma and the spindleends drop into the normal bearings-28 at the inner ends of the deck arms.

'lhis-operation placesthe fresh roll in the normal bearings 28 beneath the core roll and web running therefrom but; the fresh rollis stationary and has the free-edge 71 of 'its'web coatedwith glue 72 and pointing m up *ardly at the rear portion of the circu1nference of the roll as shown. in Fig. 3 of the drawing. 1

At this same moment, the pin 51 onthe collar 5O'that- -ismounted'on the spindle fl,v '7

preferably extends substantially horizontal 1y but behind: thefree edge'71. of the web. The preciselocations of the freeend edge 71,0f fl161W8b and-the pin 51 on the collar depend entirely upon the speed at whichit:

is desired to drive the running web i from the core-roll at the time the union with the fresh web isto-be made but. in practice we slow the press down and thus reduce thespeed of travel of the exhausting; web so as to avoid sudden strain on the running web that might cause that'web to tear by requiring the fresh roll' to suddenly start rapid unwinding rotation. y

In accordance Withour invention We utilize the running exhausting web to setup rotat-ionof the fresh-roll and. then we unite the webs and cut the exhausted. web allowing the out exhausted web to draw'the fresh web through the press.

The next step therefore in the operation is to set the new or fresh web into rotation and this we dob'ymeans-tha-t will now be explained; reference being made particularly to Figs. 13 and 11 of the-drawings;

Extending; crosswise of: the press at the.

a soft composition roller 89, which roller 'extends horizontally across and above. the running.exhaustingweb which we designate 90 in Figsf3 and ll of the drawings.

The rock-shaft 86 also hasactuating levers 91, which depend therefrom and which have a horizontal pin 92 extending laterally from the lower end thereof.

The pin 92, when the lever 91 is in the normal position as in Fig. 1, is engaged by a vertical pin 93 to hold the lever down, but when it is desired to start the fresh roll 16 to revolving immediately prior to the union of the two webs, the pin 93 is withdrawn and lever 91, is swung laterally, thereby rocking shaft 86 and moving the horizontal composition roller 89, against the upper side of the running web 90 thereby depressing the running web until it comes into frictional contact with the circumference of the fresh roll 46.

During this operation, the operator of the lever 91 varies the pressureof the composition roll until the friction of the running web causes the fresh roll to revolve.

As the fresh roll begins to revolve the free edge 71 of the web thereon approaches the contact point between the running web 90 with the fresh revolving roll and as the said edge 71, with theglue 72 on its upper surface passes under and in contact with the running web, the two webs are immediately united.

While rotation of the fresh roll is being set up and the union of the two webs made, the spindle 4.7 carrying the fresh roll is also being revolved and in turn is revolving the collar 50 and the pin 51 thereon. This pin 51 is therefore now about to perform a useful function of operating mechanisms that will cut the runnin web, as will now be explained, reference lacing made particularly to Figs. 3-7-.-11-12 and 13 of the drawings. 7

As collar 50 revolves, it carries the pin 51 with it and the relative position of this pin with respect to the glued edge 71 of the web is such that the pin trails behind such edge so that after the glued edge is united with the running web 90, the pin 51. will, during its swing, strike the lower free end 94, of an actuating lever 95 to rock the latter.

The lever 95, is ivoted at 96 to one of the vertical bars 20 o the press frame and its upper end is pivotally connected to one end of a rocking slide-bar 97 which latter extends through a guide or keeper 98 and has a down turned hook 99, on its rear end.

The under side of the slide bar carries a pin or projection 100 which latter, when the slide bar is drawn outwardly, engages a cam plate 101 and thereby causes the hookend 99 of the bar to be raised, for a purpose that will presently be explained. I

.Bearing brackets 102 are attached to the press frame and these brackets support a horizontal rock-shaft 103.

An arm 104, is carried on the outer end of the rock-shaft 103 and said arm extends upwardly and carries a laterally-projecting pin 105, with which the hook 99 on the slidlng lever 97 normally is engaged.

The rock-shaft 103 also carries a counterweight 106 which weight is lifted as lever 97 is drawn outwardly to swing the arm 104; rock the shaft 103 and by moving sprocket chain 117, tilt knife or cutter 115, as will presently be better understood and as these operations take place, the weight 106 will be elevated so that as soon as the cutter has been actuated the cam 101, willlift lever 99 and disengage the pin 105, so the counterweight 106 can return the parts to the normal position.

In other words, hook 99, by engaging arm 104-, holds the rock-shaft in one position against the action of the weight 106, which weight, when the book 99 disengages arm 1041, causes the rock-shaft 103 to make a partial rotation, for a purpose which will now be explained.

The inner end of the rock-shaft 103, car ries a sprocket wheel 107, which latter is fixed to said shaft and has only a partial rotatilonC1 with said shaft when the latter is roc re Below the rock-shaft 103, the frame of the press carries a horizontal angle-bar 108 which extends all the way across the press frame from one vertical bar 20 to the other. This angle bar carries two brackets 109 and these brackets pivotally sustain two long bell-crank shaped arms 110,-one 1e 111 of each arm extending up and under t e shaft 61, while the other leg 112, of each arm extends outwardly between the deck arms 21, and carry a cutter frame 113. This cutterframe carries a horizontal shaft 114, to which a cutter-plate 115, is attached.

The end of the cutter shaft 114 extends through the leg 112, of the bell-crank shaped arm and this projecting end carries a sprocket 116 so that a sprocket chain 117 may pass around the

sprockets

107 and 116 and rock the cutter shaft 114 each time the shaft 103 is rocked as the result of the pin 51 on collar 50 striking and actuating lever 94.

As cutter-shaft 114 is rocked, the cutter blade or plate 115, will be forced downward and throu h the running web 90 as shown in broken fines in Fig. 3 of the drawing.

After the running roll has been out the spindle in the spent core roll will. be en gaged by a hoist device and lifted from the lift-arms after which the arms may be lowered by dropping the rack-bars 52 back to their-normal positions and when doing this, the lift-arms will ride down over the ends of the spindle then in bearings 28 and thus swing the arms back until the latches 66 engage and retain them at the sides ofthe rack-bars.
