Specification of Letters Patent.

Patent-ed Feb. 3, 1914.

Application iled July 5, 1912. Serial No. 707,723.

To all 'whom it may concern;

Be it known that I, ROBERT I-IoE, a'citizen of the United States, residing at New York, co\rrnty of New York, and State of New York, have invented certain new and useful Improvements in IVeb-RollR-en'ewe'rs, fully described and represented in the following specification and the accompanying draw-l ings, forming a part of the same.'

This invention relates tol improvements in mechanism for substituting a full web roll for an expiring web roll in machines which derive their web supply from rolls, the mechanism being particularly adapted foruse in high speed web printing machines,

but applicable alsol in machines of other classes, such as bag machines, envelop ma*v chi es, and the like, in ,which it is important to renew the web supply without stopping the machine. p

The especial object of the present invention is to provide a roll renewing mechanism for printing machines by which the web supply may be renewed 'without stopping the ,y

press and the control of the new web and expiring web shall be such as to secure certainty in operation at comparatively high speeds, while the mechanism shall be compact and convenient of access, so as not to substantially increase the floor or vertical space required for the printing press, and

permit a number 0f decks to be used without interfering with the convenient access to the press parts and direct web run rekquired in modern web printing presses.

In the accompanying drawings forming a part of this specification there is illustrated a web roll renewer suitable for high speed printing presses and embodying all the features of the invention in theirv preferred form, and this construction will now be 'def scribed in detail, and the features forming*` the invention then particularly pointed out in theclaims.

In the accompanying drawings: Figure 1 is a side elevation of the mechanism. Fig. 1

2 is a plan view, broken away at the middle for purpose of illustration. Fig. 3 is an end elevation looking to the right in Figs. 1 and 2Q Fig. 4'is a plan view ofthe spent roll delivery mechanism.

Fig. 23 is a detail of the flexible coupling of Figs. 21 and 22. Fig. 24,1s-a diagram of the electric circuit, motor and control devices.

Referring'now `to the drawings,- A is thev frame in which the mechanism'. is mounted,

this framepreferably being atA the' end of the printingpress `with one or more of the rollrene ing mechanisms mounted therein one abov the other, accordingto the number of printing decks in the press. On the rear end ofthe frame A are a pair of fixed tracks 10 upon which slides the roll carriage 11 by which the new web roll X is moved forward into osition for attachment of its web to the we y of the expiring web roll Y,N the web roll X being carried by its spindle or shaft 12in bearings'13 at the forward end-.of the carriage, these bearings `13 being pivotally connected to the carriage at 14 and spring pressed to swing the bearings downward and rearward bysprings 15 v .asdescribed hereafter. Above and rearward of the carriage tracks 10 are preferably tracks IGarranged to support the spindle 12 of the4 new web roll and permitl itto be rolled forward and down onto the bearings 13 so that the'web roll X may be in position` on tracks 16, ready for transfer to the ca'-4 riage at thedesired time.

The carriage 11 is provldecl with a brake A and margin adjuster, the brake preferably consisting, a's shown, of top and bottom brake shoes` 17, 18 engaging the concave brake disk 19 on the web spindle 12 and carried by vertically swinging arms 20 pivoted at 21 to standards 22 on carriage 11. The shoes 17, 18 are adjustable to vary the braking pressure by adjusting screw 23 and, by releasing this screw, the top shoe 17 may be thrown back with arm 2O for admission of the roll shaft to its bearings :13. The bottom shoe 18 may be similarly swung back on its arm 20 independently of the screw, this arm 20, with its shoe 18, being normally held in braking position by pin 1 engaging a locking extension at the upper end of a curved slot 24 in a swinging trip 25 depending from the adjustable block controlled by screw 23 and normally pressed forward by spring 26 into position to lock the shoe 18 in braking position through pin 1, the lower end of the trip 25 engaging fixed stop 27 at the proper point in the forward movement of the carriage to release brake shoe 18, as hereafter described. Y The brake mechanism, with arms 20 and standards 22, is carried on a slide 28 mounted to move transversely to the carriage and adjustable by adjusting screw 29 to move the brake mechanism and roll X sidewise for margin adjustment.

The advancing carriage is stopped until the pasted leading end of web a2 on roll X is in proper position for final advance by swinging stop 30 normally moved upward into position to engage and stop the car riage by spring pressed rod 31, and depressed to release the carriage at the proper time by cam 32 carried by the roll shaft 12 and engaglthrough pipe 47 valve 48 so .that the pressure may be regir,

ing head 33 on the stop, such stop mechanism being provided at each end of the roll.

The carriage 11 with the new roll is 'preferably advanced along the tracks 10 for roll renewal and the yieldingl pressure on the web roll preferred for-pasting and web feeding is preferably secured by compressed air, the mechanism shown for this purpose being as follows The carriage 11 carries at each side of the frame a fixed rack 34 meshing with gears 35 on short shafts mounted in the frame and carrying outside the frame A gears 36 driven by intermediates 37 from gears 38 on opposite ends of shaft 39 extending across the machine, this'shaft 39 being driven by gears 40 thereon meshing with rack 41 carried by the piston of compressed air cylinder 42, which piston is moved in opposite directions by the admission of compressed air to one or the other end of the cylinder through supply and exhaust pipes 43, 44 controlled by valve 45 actuated by hand-lever 46, and to which air is supplied from any source controlled by regulating lated thereby and then controlled as desired by. handle 46 and valve 45, the exhaust being by pipe 49. A hand operated relief valve 20() is preferably provided for use as hereafter described.

The starting device for securing the de` sired speed of rotation and control of web roll X before its web is'attached to the expiring web preferably consists, as in the form shown, of driving belt 50 mounted below the carriage and swung upward into driving contact with the lower side of the roll X and downward out of such driving contact, this belt 50 being carried by pulleys on its driving shaft 51 and shaft 52, the latter mounted in arms 53 swinging concentrically with driving shaft. 51, shaft 51 'being driven to secure the desired speed by bevel gears 54 from driving shaft 55 preferably driven from the press, so as to assure correct timing, but which may be independently driven with the required timing. The swing ing arms 53 are normally drawn downward to hold the driving belt 50 out of position for contact with roll X by spring pressed rodsv 56 and rocked upward against the spring tension of rods 56 by arms 57 pivoted to arms 53 and carried by rock shaft 58, which is rocked by arm 59 actuated by piston in pressure cylinder 60 to which compressed air is admitted to raise the piston through pipe 61 extending to theopposite or operatingside of the press, and there controlled by valve 62 having air inlet pipe 63 connected to any suitable supply. The valve 62 is controlled by hand through handle 64 to admit air for bringing the belt 50 into contact with roll X for starting the latter, the handle then being thrown into vertical position, and the handle 64 is thrown downward to actuate valve 62 to release the air pressure in cylinder 60 and lower -the belt 5() out of contact with the roll by the engagementv of roll carriage 11 with the upper end of the handle, at the proper point in the forn ward movement of the carriage the top of the handle 64 being provided with a spring supported trip l65 having its forward side inclined so as to permit the carriage to rcturn past the handle 64 without operating it, but to vengage the trip 65 and operate the handle on its forward movement.

Referring now to the means for removing the expiring roll from the path of the new roll, and the web attaching and feeding devices, a vertically swinging carrier, which I call a shifter, is mounted on frame A, this shifter consisting in the form shown of bars 66 pivoted at 67 in bearers 68 pivoted at 69 in the frame A, the bars 66 carrying bowls 70 running in curved slots in fixed-brackets 71 so that the bars k66 are rocked on their pivots 67 at the same time that they are swung downward with bearers 68.' The shifter `bars 66 carry at their ends next tracks 10 supporting surfaces 72 in line with the tracks 10 onto which ride the roll bear ings 13 in the extreme forward position of hooks 74 forming roll holders. These bearings 7-3 and hooks 74: are mounted on carriage 75 having a limited movement on tracks in line with tracks 10, so that this after.

carriage 75 may be moved back a short distance under the pressure of the advancing vbearings 13 and spindle 12, to bring the shifter into operation, as described here- The supports 72 over which bearings 13 pass onto the shifter consist of bridges, as shown clearly in Fig. 13, beyond and below which space 76 is provided by cutting out the shifter to permit the bearings 13, which are carried by side arms, to drop from the position shown in Fig. 12 to that shown in Fig. 13, and return below the bridge, as the carriage 11 is withdrawn.

The shifter bars 66 carry locking catches 2 engaging depending arms 3von hooks 74, to lock these hooks in position to hold the roll spindle in bearings 73 and to lock the carr-iage'7 5 in its forward position, these locking catches 2 being pivoted and weighted to swing into locking position, and being .moved to unlock the hooks and release the carriage by swinging trips 4 pivoted on the frame and actuated by links 5, Whichalso actuate swinging trips acting against arms 3 to raise the hooks 74, and release the roll spindle, links 5 being `actuated from arms 77 on rock shaft 78 extending across the frame and operated by handle 79, this rock shaft 78 also carrying arm 80 connected by link 81 to an arm on rock shaft 82 extending acrossthe frame and carrying at each side of the frame arms 'connected by slotted links 83 to cont-actlevers 8l, presently to be described. Catch 24 on one side of the frame is preferably set'orl actuated so as to release its end of the carriage 75 slightly before the other end, for breaking the expiring web as described hereafter.

The carriage 75 carries a margin adjuster, no brake being necessary with the web feeding mechanism shown. This margin adjuster is shown in detail in Figs. 7 and 8. The hooks 74 forming one side of the roll spindle bearings on carriage 75 are carried by sleeve 85Amounted on adjusting screw 86 in carriage 75 at the operating side of the frame, and this sleeve carries stop arm' 3.

At its inner end the screw 86 carries the conical shoe 87 which enters brake pulley 19 when the roll spindle 12 is in bearings 73,

this' shoe being `carried by arms pivoted on box 88 sliding von a boss extending inward from carriage 75 and'secured to screw 86,

' the box 88 and shoe 87 being pressed inward Screw 86 is adjusted by head 90 and spring pressed outward by spring 93. Splithalf nut 91 is carried by pivoted arm 9i and is clamped or unclamped on screw 86 by rocking arm 94, which is spring pressed to lock the nut on the screw threads by spring 95, and held against the spring pressure to release thel nut by adjustable stop 96 on fixed arm 97. Vhen the half nut 91 is clamped upon hand screw 86, box 88 with shoe 87 and the web roll Y may be adjusted for margin by rotating screw 86 and when half nut 91 is released from screw 86,: the screw 86 with shoe 87 may move endwise in either direction against spring 89 or 93, .according to the position of the brake pulley 19, as controlled by the margin adjuster on carriage 11, as described hereafter.

' Any suitable driving mechanism may be used for raising and lowering the shifter 66. In the construction shown, the bearers 68 carry gear segments 98 engaging gears 99 on shaft 100 extending across the n1a' by a two-way solenoid 109, the shaft 106 being driven from a reversible motor controlled by contacts so that the shaft 100 may be driven from shaft 106 in either direction to drop the shifter and return it to normal position. The flexible coupling secures a yielding action at the ends ofthe movement of the shifter and permits the shifter to bel forced home on return to its normal position without danger of locking the worm and worm wheel.

`The shifter control is as follows The carriage 75, in its most advanced posit-ion (toward roll 126), presses contact buttons 7, thus moving contact levers 84: and closing contacts for clutching shaft 106 to worm 104 for moving the shifter downward, and at the end of the downward movement of the shifter the circuit is broken by circuitbreaker 10.2 actuated by trip 8 to stop the shifter. The circuit is then closed again inv the reverse direction by actuating handle 79 to move contact levers 81 and buttons '7 back to normal position by links S3, and the motor is then Astarted in the opposite direction and clutched to worm 101Mo return the shifter to normal position, and the circuitis broken to stop the shifter on its full return by the engagement of another circuit A livered beneath the roll renewing mechanism after substitution of the new roll, and preferably, as shown, carried backward to the `outer end of the frame in convenient position for removal, and means are provided for breaking the expiring web from this spindle for its delivery, although the expiring web may be broken by hand `instead of automatically. The means for se.- curing these results are as follows :-Below the shifter are pivoted two arms 111 forked at their inner ends to form bearings 112 for theaspent roll spindle, these arms being carried by rock shaft 113 having handle 201 and arms 114 pressed by spring pressed rods 115 mounted in cross bar 116 of frame A, which spring pressed arms act to hold the bcarings`112 in position to receive the spent rollY spindle from the shifter. Rock shaft 113 carries, also, an arm 117 connected to the stem 118 of the piston in dash pot or'cataract cylinder 119 forming a retarding device controlling the movement in both direct'ions of the arms'lll and bearings 112, thus preventing slam by the weight of ,the spent roll or spring return. The arms '111 with bearings 112 swing vertically between tradks 120-inclined ,downward from their end'sfbelow the shifter and extending rear-l ward to the outer end of the frame below the roll advancing mechanism, and on these tracks runs a carriage 121 formed by side frames shown as having wheels running on the tracks, these frames being connected by rear cross bar 122 and havingl bearings 123 receiving the spent roll spindle 12 carrying the last unused port-ion of /the web roll Y.

The carriage 121, is held in its 'forward 'position on the incline of tracks 120 by spring. pressed pivoted catches 124 at each side of the frame tripped to release the carriage by .trips 125 on each of the arms v111', these catches 124 being shown as engaging notches on the bot-tcm of the side frames of carriage 121.

It is important that the web 'in use should run at exactly the surface speed of the type cylinder, ,and that the new web roll should be ully controlled in renewing and/feedeing` he web, in order to assurethe pasting,

'together of the new and old webs at high speed without breaking either web. p This result is secured inthe'mechanismshown by using a vdriving roll over which the web runs' to the press and which forms also an abutment against which thefpasting is done,

and making the surface speed ofthis roll adjustable so that vexactly y,the proper speed of the driving roll and old web can be maintained and this speed immediately taken up and maintainedby the new Vroll under the compressed air pressure forcing the new roll against the driving roll for pasting and feeding. Thev 4mechanism shown for this purpose consists of driving roll 126 which may be an expansion roll of any ysuit-able form,adjustable by hand screw 127 for varyin'g the diameter and surface speed of the roll, and upon this roll preferably runs an idler roll 128 shown 'as carried in swinging varms 129, this idler roll preferably having a yielding surface which may be formed of substantially ink roll composition or other suitable material. The expansion roll 126 may be driven by any suitable means, either :from the press shaft, or preferably ,from the press, and as shown is driven from driving shaft130 through .fbevel gears 131, shaft 132 and bevel gears 133 gearing upto the'expansion roll shaft 134. Instead of making the driving roll 126 expansible for adjustme'nt of surface speed, a non-expansible roll may be used and made adjustable to vary the surface speed in any usual or suitable manner.

The operation of the mechanism in roll renewing will be understood from a brief description in connection with the drawings, and especially Figs. 17 to 20, illustrating the successive steps of roll renewing,

v and Figs. 14 to 16, showing the different positions of the dropped shifter and its rollholding devices.

As shown in Fig. 1 no web is being fed'to the press, but a web roll X has been rolled 13 on carriage 11,and has been speeded up by' belt 50, in contact with its under side,

'y and the carriage with web roll X is ready to have its/web threaded upbetween rolls 126, 128, and-moved forward into contact with roll 126 for feeding the web' to the press, the upper brake shoe 17, with its arm 20 and ad'usting screw 23 being shown in dotted l'ings as thrown back for the admission of th roll shaft 12 to bearings 13, and the lower brake shoe 18 as already thrown up 't0 receive the brake trip, although this y brake shoe 18 may be thrown up later, as no braking is desired during the control of the' roll by belt 50. It will be understood that in putting in this first roll, the leading end of the web will simply be threaded through by hand, as .usual in printing presses, but thereafter the leading end 0f the new web wvill'be attached to the expiring web by this roll renewingmechanism without stopping the press. y v l In Fig. 17 the parts are shown in position with the expiring web roll Y ready to be dropped bythe shifter to permit the new web roll X to be advanced for roll renewal, and in Fig. 18 the parts are shown in the position of pasting the leading end of the new arms 111 for delivery, and in Fig. 2 0 the 95l over the tracks 16 and down onto bearings rosaoe spent roll Y has been deposited on thecarriage 121 and the latter released for delivering the spent roll at the rear end of the frame. Y

Assuming now that a new roll X isto be substituted for an expiring roll Y, and the latter in the position shown in Fig. 17, the

new web roll X has the leading end of itsweb pasted down lightly so as to bereadily detached from the roll, and has paste or other suitable adhesive applied on vits outer side for attachment to the old web, the leadingend of the web with its paste being located in a certain position relatively to the cam 32 on the. roll shaft 12. The web X. thus prepared. is rolled over the track 16 and down onto the bearingsv 13 onA carriage 11 with the top brake shoe thrown back. as shown in' dotted lines in Fig. 1. or with both brake shoes thrown back. The top brake shoe 1T is then brought into operative position by swinging the upper brake partsover into the position shown in Fig. v9. with top brake shoe 17 above brake pulley lQ'and bottom brake shoe 18 in position -below. the pulley and `held in adjustable position by hand screw 23. but braking Ipressure not being applied. `Valve 62 is then operated by moving handle 6i into the-vertical position shown in Fig. l so asto admit pressure air to cylinder 60 and rock shaft- 5S to raise belt shaft 52 and move the forward end of starting belt 50 into driving contact with the underside of roll X and speedup the web roll X to the speed required. Roll X is' preferablyT driven by belt 50 at a surface speed slightly in excess of the surface speed of roll 126. to provide for a slight drop in speed of the web roll between its release by belt 50 and engagement with roll 126. the important. result desired being that the surface speed of web roll X shall be substantial-ly the same asY that 'of roll 126 when brought into driving engagement with it.

and itjbeing especially important that webroll shall not be teo slow when the pasting takes place. 4

Assuming now that the expiring lroll Y Ahas been dropped by the shifter below thepath of roll X and its web jz/ is now running from the dropped roll Y over 'roll 126. as shown in Fig. 1S. so that the mechanism is ready for attachment of the new web a; on its roll X. handle i6 is moved by `the operator to shift valve l5 so as to admit pres- Asure air through pipe l-l to*L the inner end of air cylinder 42 and open4 pipe 43 to' discharge; so as to move the air piston to-the left in Fig. 1 and thus, through racks il. 34 and the intermediate gearing, advance carf .riage 11 with roll X ttf the right toward roll 126. the pressure being adjustedl by theregulating valve i8. During this movement of the carriage. handle 6i is moved to lthe right in Fig. 1 by engagement of the car- 'riage with head 65, and valve 62 is thus operated to cut off the pressure airfrom cyl- -inder 60, and starting belt 50 lowered out of contact with web roll X by the spring rods 56. 0

Before the web roll X has made contact with the web y of roll 126. the carriage is stopped by engagement. with stops 3() and is held until.` in the rotation of roll X,cams 32 engage and depress stops 30, as shown in Fig. 11, so as to release the carriage to advance web roll X against the web y on the roll 126. The cam 32 and pasted leading end of the web on roll X. are'so positioned that,l` on the release of stops 3Q, roll X will be brought against vweb z/ on roll 126 some time, and preferably nearly a full revolution. before the pasted edge of web m comes into contact with the web y, thus assuring the. pasting together of the two webs by the whole pasted surface and avoiding danger .of a loose flap on the new web, which might resultif lreliance were placed on bringing the pasted portion directly into Contact with the web 1/ by the advance movement of the new roll. This also aids in securing exactly the same speed of the two webs before p asting.- and in avoiding `danger of breaking one web or the other, or failure in proper pasting. The position of pasting is shown in Fig. 18. and web m is now carried forward with web 1,1/ to which it is pasted; until web z/ is broken 0H. as 'described hereafter. completing the4 substitution of web .r for web y.

When the new web roll X has been advanced to the expansion roll 126 and web :n.substituted for web y, the brake shoes 17,I

18 are adjusted bymhand screw 23 to secure the lbraking pressure desired, and the web roll X with its shaft spindle 12 is adjust-ed sidewise in bearings 13 by hand screw 29 for margin adjustment, as usual in printing machines. The air pressure on carriage 11 usually will require adjustment, also` as quite heavy pressure is preferably employed in advancing the carriage to bring the web roll X into contact with web 1/ on expansion roll126 so as to secure the-quick advance and strong pasting pressure desired, and such heavy pressure, if used, is not'suitable for continuously feeding the web. The air pressure, therefore', is preferably lessened and adjusted as desired, by opening hand relief valve 200 for quiek release of the high pressure, and adjusting the pressure by regulating valve 48 and closing refectfeed of the web a: beingvthus secured as i web roll X decreases in size, and web` roll X is thus advanced with its carriage 11 moving onk tracks 10 until the roll X is reduced in size so that the bearings 13 move from the ends of the fixed tracks 104over the bridges 72 on shifter bars 66, so as to, carry roll lspindle 12 into the open bearings 73, spindle 12 raising the hooks 74 as it moves into the open bearings 73, so as to permit the spindle to pass the hooks, which then are lowered to embrace spindle 12 and hold it in the bearings 73. As roll X decreases in size and the-roll spindle 12 is thus moved into the openl bearings 73, brake pulley 19 receives the conical vshoe 87 on margin adjuster box 88, between the brake shoes 17 18, shoe 87 and box 88 being then movable sidewise in either direction against spring 93 or spring 89 to permit the shoe 87 to take the position of the brake pulley 19 for margin adjustment, as halffnut 91 is then raised from the threads of screw 86 to release the. latter, by the engagement of its arm 94 with trip 96, as shown in full lines in Fig. 8,- so that the marginvadjustment can bo controlled by hand screw 29 on carriage 11 during the feedingy off of the paper roll as long as arm 94 is held depressed by `trip 96, and half nut 91 thus held raised. The. bearings 13 on `passing Ithe bridge 72 and delivering the spindle 12-,to bearings 73, are dropped through the space -76 by l springs 15`to be rocked upward ontb tracks 10 against the tension of springs 15 on the rearward movement of the carriage 11 after\ the shifter is dropped (see Figs. 11 to 13).

Referring now to .the operations of dropping .the expiring roll, for pasting on'the new web, breaking the expiring web, andi delivering the spent roll spindle, the carriage 75, with the expiring vroll Y in bearings 73, is moved backward from the position shown in Figs. 1 and 9 .to that shown in Figs. 10 and 17, as the web roll decreases in size, the arms 3 on hooks 74 passing weighted stops 2 which then swing up to lock the hooks and hold the carriage in this position. The carriage thus strikes both push-buttons 7 at opposite sides of the machine,l moving contacts 84 sfbas to'close an electric circuit to start the reversible motor' 200 to drive shaft 106'and operate solenoid 109 tqactuate clutch 107 torotate shaft 100 through worm 104, gear 103, and flexible coupling 101, to the right in Fig. 1, and, by

engage-ment of gears 99 with segments 98,

swing the bearers 68 downward with shifter bars-66, the shifter bars being also rocked on their pivot 67 by \bowls 7.0 running in fixed cam grooves 71, and the shifter with roll Y being t-hus moved from the position shown in Figs.v 1 and 17, tothat shown in Figs. 14 and 18, with lthe expiring roll Y carried by the shifter and its web g/ running upward over expansion roll 126, as shown ,clearly in Fig. 18, and shaft 12 held in the open bearings 7 3' by hooks 74. As the shifter Areaches this position, circuit breaker 102 is actuated by trip "8 to un/clutch and `stop shaft 100 and stop the reversible motor.

v In connection with dropping the shifter, as above described, it is necessary that the lower brake shoe 18 shouldfbe moved out, 1

Vby the engagement of lever 25 withstop 27 which moves lever 25 rearward against the tension of spring 26 thus releasing pin 21 on arm 20 and allowing this arm with the brake shoe 18, to drop ,from the position shown in Fig. 9 to that shown in Fig. 10. Spindle k12 is then free to drop away from top brake shoe 17, as the shifter moves downward. The change of margin adjustment control is secured by arm 94 passing o-ii' trip 96 as carriage 75 reaches the position` in which the"'shifter is started downward', the half nut 91 thus being thrown down ward -to lock on the screw threads of hand screw 86 bythe upward movement of arm 94 under pressure of spring 95, as shown in dottedllines in Fig. 8, so that screw 86 with bmi 88 and shoe 87 engaging pulley 19. is not free to move sidewise, but locks the web roll in its margin adjustment, which now may be varied by turning screw 86 in nut v91 by head 90.

The shifter having been dropped with expiring roll Y, the carriage 1l is ready to be withdrawn from the position shown in Fig. 17 to that shown in Fig. 1, for receiving and advancing another roll. In withdrawingtlie carriage the operator throws handle 46 to the left of its norma-l vertical position, shown in Fig. 1, thus shifting valve45 to admit pressure air to the rear end of air cylinder` 42l through pipe 43 and connect pipe 44 to exhaust, thus moving the piston/tto the right and returning carriage 11 to the left, in Fig. 1. The regulating valve 45 'maybe adjusted for higher pressure to return the carriage 11, or may be adjusted after re# turn for the higher pressure desired in advancing the next web roll. l

The new web having thus been pasted to the expiring web y and the web renewal completed with the parts in the position shown in Figs. 14 to 18, the expiring web y is to be broken and the spent roll Y delivered, as follows: The handle 79 yis first thrown from the position shown in Fig. 14 to the position shown in Fig. 15, which-rocks shaft 78 and through arms77 and links 5 moves trips 67 to rock weighted catches 2 to release arms 3 on the shafts of hoofs 74 and permit the latter to be raised for (releasing spindle 12 of web roll Y. This moveido ment of catches 2 also releases carriage 75 and permits it to slide downwardfon the shifter a short distance, from the position shown in Fig. 14 to that shown'in Fig. 15. The breaking of the web y is secured by this sliding movement of the carriage 75, the trip et and catch 2 on one side vof the frame being arranged to release that end of the carriage 75 slightly before the other end is released, so that one end of the carriage slides down before the other and thus tears the web across, detaching the spent roll from the new web. The parts are now in the position shown in Fig.4 15, which corresponds with Fig. `18, except that the carriage has been released and moved downward slightly from the position shown in Fig. 18 and the web y has been broken. The handle 79vis now thrown from the position shown in Fig. 15 to that shown in Fig. 16, thus moving the links 5 farther to swing trips 6 against arms 3 and positively raise hooks 7.4 'to release spindle 12 of roll Y, which spindle then rolls out of the openV bearings 73 and downward into bearings 1.12 on arms 111. .This movement of lever 179 also, through link 81, shaft 82 and its arms, and slotted links 83, moves contacts 81 to return push buttons 7 to normal position and close contacts toactuate the reversible motor and through solenoid 109 to clutch in worm 104 and rotate shaft 100 to the left in Fig. 1,.\ thus through segments 98 actuating the vbearers 68 to carry shifter bars 66 back to normal position, and on thefull .return Qf lthe shifter circuit breaker 105 is actuated by trip 9 to stop the motor and unclutchL shaft 100. If desired, another circuit controller or controllers 201 may be added to enable the operator'to stop, start o r reverse the shifter by hand atany pointin its movef ment. The position of the parts with the spent roll transferrer to Abearings 112, and the shifter ready to return .te normal posi.- tion when handle 'T 9 is operated, is shown in Figs. 16 and19. Shaft 113 is now rocked by the weight of the spent roll Y` against the spring pressed rods llvsanddash pot 119, thus lowering arms 111 with spent roll Y-and its spindle 12, so as to drop the spindle 12./into bearings 123 on carriage 121, and shaft 1'13 is then 'rocked by its handle 201 to move the arms 111 down and rock.

spring catches 121 to release the carriage,

the carriage 121 then running ldown the in- Aeline'andover tracks 120 to the rear end of frame A to deliver theaspentroll in conven ient` position for removaLthe positions of the parts during this operation belng shown in F igs.` 19, 20, and 4, and the final position of `the* carriage in Figs. 1 and 3. Rock shaft 113 is then returned to position by spring pressed rods 115 on the release of handle 201;` this return movementas Awell as the downward movement being'retarded as de-- sired by dash potv 119, and spring catches 124 returned to normal position to held car- Vriage 121 on its return; all as shown in Fig. 1.

rlhe invention is not be limited to the exact form o'r arrangement of'the apparatusl illustrated, but many changes may be made while retaining the invention defined by the claims. The arrangement shown by which the abutment roll not only secures the pasting operation desired, but acts in itself as the driver forfeeding oit a large part of the web from` the new web roll and controlling the latter, secures a. very eiicient operation with a simple and compact construction, but it will'be understood that many features of the invention may be used in constructions in which the feeding voti" and control of the new web after pasting is 'otherwise secured.
