These arms are arranged in and also the means which actuates the device pairs-one bar of each pair being carried by each which severs the expiring web from its core. of two of said vertical end-bars 26 and each of Fig. 6 illustrates a horizontal sectional detail the pair of arms being in the same horizontaly through the parts shown in Fig. 5, as viewed on plane but each pair being located in a different the line 6 6 thereof. horizontal plane from each of the other pairs of Fig. 7 shows a horizontal sectional detail arms.

. purpose These pairs of arms are utilized to sustain the spindle-ends of roll-shafts 23 on which are rigidly mounted the rolls of web-paper 23 that are to be fed to the press.

Each of said arms 21 carries a horizontal track 33 at its inner side on which there is mounted a carriage 3| and each carriage lhas a bearing-block 32 in which the ends of the spindle or roll-shaft are to be seated when the rolls are first hoisted in place at the outer ends of the pairs of arms.

Endless chains 33 are attached to the carriages and pass around sprockets 34 on a horizontal shaft 35 so that when the roll of paper is to be pushed rearwardly into running position, the carriages will travel together and deliver the two ends of the spindle or shaft 23 into the seats 35 at the inner ends of the pair of arms.

As the spindle 23 is seated in the arm-bearings 35 it engages a lever 31 of a valve 35 (see Fig. 1) and opens that valve, so as to immediately allow air, under pressure, to pass from supply pipe 33 to pipe 45, and be conducted by the latter to an air-cylinder 4| which immediately swings a beltframe 42 toward the under side of the roll, for a that will presently be explained.

The air-cylinder 4|, as best shown in Fig. 16,

l comprises anouter cylinder 43, closed at one end and open at the other, and an inner cylinder 44 which enters the open end of the outer cylinder and has a central chamber 45 which is open to the chamber of the outer cylinder.

A packing 45 is placed around the open end of the inner cylinder and makes a tight joint with the inner chamber-wall of the outer cylinder while the pipe 43 enters the inner cylinder and communicates with the central chamber 45 thereof, whereby air under pressure may enter said chamber 45 of the inner cylinder and pass directly into the chamber of the outer cylinder.

'Ihe entrance of this air tends to force the two cylinders apart and as the outer end of the inner cylinder is merely pivoised to a bracket 41 while the opposite end of the outer cylinder is attached to a swinging bracket 43, the entrance of air between the two cylinders will tend to force the outer cylinder to move and swing the bracket 43. This bracket 43 is attached to a rock-shaft 43 which extends horizontally across the press from one vertical endbar 25 to another, and said bracket carries a screw-threaded rod 49 on which there ,is a threaded strap 53, which latter is attached to a stem that projects from the closed end of the outer cylinder 43.

The result of these connections between the air-cylinder 4I and the bracket 45 is, that when air is admitted 'between the two cylinders, there is a constant tendency to turn the rock-shaft 43.

By reference to Figs. 1-14-15 and 17 of the drawings, it will be seen that a series of arms 52 are attached to the rock-shaft 43 and that each of thwe arms is attached to one end of a beltframe 42 which'comprises a series of curved bars 53. This frame 42 therefore swings as the shaft 43 is rocked.

On the rock-shaft 43 there are provided a plurality of loose pulleys 54 and each pulley carries on its hub, at one side thereof, a sprocketwheel 55.

The lower end of the swinging belt-frame 42 has -a cross-bar 55- (see Fig. 14) on which there are carried a plurality of yieldingly mounted yokes 51 and each yoke mounts a loose pulley 53. It will be noted that there are as many yokes and loose pulleys 53 as there are loose pulleys 54 on the rock-shaft 43 and the

pulleys

54 and 55 are in allnement so that flexible belts 55 may be passed around those alined pulleys and at times be driven when the pulleys 54 are rotated by the ,turning of the sprockets 55, as will presently be explained.

By reference to Figs. 1-14 and 17, it will be noted that a cross-bar 5| extends horizontally across the belt-frame 42 and thaton this barthere are mounted a plurality of idler pulleys 52' around which the back-stretch of the belts 53 pass.

Below the rock-shaft 43 there is located a horizontal clutch-shaft 52, one end of which (see Figs. 12-13 and 17) is carried in a bearing 53 at the left side of the press, which bearing is mounted on the rear vertical edge of the vertical end-bar 25 of the frame. The outer side of this bearing 53 has a cone-faced recess 54.

At the inner side of this ybearing 53 (see Fig.

13) the clutch-shaft 52 carries a clutch-memberl 55 which has a sprocket-wheel 55 mounted thereon and also has a head with a conical recess 51. This clutch-member is loosely carried on the clutch-shaft 52 at the inner side of the bearing 53 and is constantly driven by a sprocket-chain 53 which passes around the sprocket-wheel 55 and also passes around another sprocket 53 (see Fig. 12) that is mounted on a short stub-shaft 15 which has a bevel gear 1| that meshes with and is drivenby another bevel gear 12 on a vertical shaft 13.

The clutch-shaft 52 carries a cone-head 14 at its outer end whose cone-surface confronts the cone-recess 54 in the outer side of the bearing 53 while at the inner side of the clutch-member 55 said clutch-shaft 52 carries another cone-head which confronts the conical recess 51 in said clutch-member.

Bearing in mind that the clutch-member 55 revolves constantly and is normally free on the shaft 52, if cone-head 14 is moved into recess 54 of the bearing 53 it will hold said shaft 52 against turning, while at the same time head 15 is withdrawn from the recess 51 in the revolving clutchmember 55. If the reverse operation takes place, and head 15 is forced into recess 51 it will connect shaft 52 with the revolving clutch-member while at the same time the head 14 is with- I drawn from the recess 54 of the bearing.

The means therefore, for simultaneously moving the

heads

14 and 15 will now be explained, reference being made particularly to Fig. 13.

A bracket 15 attached to the rear vertical face of vertical end-bar 25 of the press, sustains a horizontall bar 11 while an adjustable screw-threaded rod 13 passes through a threaded supporting bracket 13 which-is also attached to the vertical end-bar 25 of the press frame. Two levers 33 and 3| have theirr upper ends pivotally attached to the opposite ends of the upper horizontal bar 11 while lever 33 straddles the outer end of shaft 52 and engages the outer face of the cone-head 14 and lever 3| straddles the shaft 52 and engages the inner side of the head 15. The extreme lower end of lever 33 engages the longitudinally-movable rod 13 near onevend of the latter, while the lower end of lever 3| loosely engages the other end of said movable rod 13.

A hand-wheel 32 is attached to the outer end of the movable threaded rod 13 by which the latter may be turned.

Obviously, by turning the wheel 52 in one direction, the rod 13 will be drawn to the right in Fig. 13, which will swing the lower end of lever 5| toward the right and move the clutch-head 15 into the recess 51 of the clutch-member 55 and connect shaft 62 with the rotary clutch-member and thus drive the shaft 62, while that same movement of the rod 18 to the right will swing lever l to the right and disengage the cone-head 14 from the recess 64 in the bearing. A reversal of the direction of movement of rod 14 will reverse the positions of heads 14 and 15A and thus stop shaft 62 from rotating.

When shaft 62 is engaged with the clutch, it will revolve, and as this shaft carries a plurality of sprockets 83, around which sprockets chains 84 pass, which sprocket-chains also pass around the sprockets 55 on the pulleys 54 of rock-shaft 49, those pulleys will be revolved and the belts 59 will be caused to travel.

When the fresh roll of paper 29 is placed in position withV the spindle-ends resting in the bearings 36, the end of the spindle will engage the lever 31 of valve 38, as shown in broken lines in Fig. 1, and open that valve. In Fig. 17, the roll is presumed to have just been dropped into the bearing, but the `actuation of lever 31 has not yet been started.

The opening of the valve 38 allows air to pass from pipe 39 to pipe 40 and from the latter into the inner cylinder 44 andbuild up pressure in the outer cylinder 4,3 against the closed inner end thereof. This pressure will push the outer cylinder lengthwise of the inner cylinder and move the stem of said outer cylinder upwardly so as to swing the bracket 48 and rock the shaft 49. As this shaft 49 is rocked, it will swing the lower end of the belt-frame'42 upwardly, and bring the upper stretches of the belts 59 against the cir-- cumference of the roll 29.

In the meantime, the expiring roll has been lifted out of the bearing 36 and moved upwardly, while still unwinding and feeding to the press, for the purpose of vacating the bearings 36 and making room for the fresh roll to be placed in -the bearings.

The means for engaging the spindle-ends and lifting the expiring roll to elevate it and make room forthe fresh roll, are substantially like those employed in the Johancen-Kehoe Patent 1,664,176 hereinbefore referred to, and a brief description thereof is believed to be sufficient.

At the inner side of each vertical end-bar 26 of the press frame there is provided a vertical rack-bar 85 which extends from a point below the lowermost deck-arms to a point above the uppermost pair of said deck-arms. The vertical movement of the rack-bars is the equivalent of the distance from the bearing 36 upward to the point where the expiring roll is to be lifted.

The lifting of the rack-bars 85 is effected through a motor-driven vertical shaft 86 (see Figs. 1-2 and 7) carrying a worm 81 near its lower end, which worm meshes with a wormwheel 88 on a horizontal shaft 89. On this same horizontal shaft 89 are two gears 90,-one at each end thereof, and these gears mesh with and drive interposed idler gears 9| which latter engage the racks on the edges of rack-bars 85.

The upper end of the vertical shaft 86 carries a gear 92 (see Fig. 2) which meshes with and is driven by a pinion 93 on the shaft of a reversible motor 94 so that when the motor is operatedfit will drive vertical shaft 86 and through the gearing at the lower end of said vertical shaft, the racks will be moved up or down vertically.

The means for stopping the motor when the racks have reached their limit of up or down movement, is disclosed in Figs. 2 and 3, wherein, a vertical arm 95 is shown as projecting from the upper end of the rack-bar, and this arm carries two

trip devices

96 and 91. When the motor has been started, the rack will move upwardly, and continue to so move, until the trip device 96 strikes a snap-switch 98, whereupon the motor will be stopped.

When the return movement is made, the trip 91 will strike another snap-switch 99 and again stop the motor.

Each rack-bar 85 is provided with a plurality of pivoted lifting arms |00,-one above the other and adjacent each of the decks. These arms are pivotally connected at their lower ends to the two rack-bars so they may operate in pairs, that is, one arm on one rack-bar cooperates with a like arm on the other rack-bar to form a pair of arms. Each pair of said arms |00 have bearing recesses |0| in their upper free ends, as shown in Figs. 4 and 17, for engaging, when swung outwardly,

under the opposite ends of a spindle 28 on which the exhausting roll is mounted.

A roller |02 is carried at the upper free end of each swinging arm and this roller, when the arm is released and its upper end swings outwardly, will engage and ride on the upper edge lof an inclined bar |03 and thus guide the spindle 28 and the expiring roll 29 as the latter is raised for the purpose of making room in the bearing 36 for the` spindle of the fresh r'oll.

When a fresh roll has been started and its web fed through the press, the rack-bars 85 will be in their lowered positions and the swinging arms |00 will be swungback where they are held by means of latch-bolts |04 which are shown in Figs. 4-17 and 18.

These latch-bolts are attached to the front edge of the vertical end-bars 26 of the press frame and are released by energizing electromagnets |05 which actuate armature-release levers |06.

Spring plates |01 yieldingly bear against the rear edges of the swinging arms |00 and when the bolts |04 are retracted, these spring plates push the arms forwardly until the rollers |02 engage the edges of the inclined guide bars |03, at which time the recesses |0| in the upper ends of the arms have position immediately below the spindle-ends as shown in Fig. 17.

Presuming now, that the running roll is nearing exhaustion and the same has been elevated by the lifting arms and racks into the position shown in Fig. l, and a fresh roll has been positioned on the deck beneath the raised running roll. f

This fresh roll has previously been prepared in that the under side of its flap |08 has been secured down by the application of paste |09 at spaced intervals and at points setback from the marginal edge of the flap.

To the outer side of the flap |08, also at spaced intervals there are applied coatings of a cement ||0 of greater tenacity than the paste |09 at the under side of the flap. These applications of cement ||0 are nearer the marginal edge of the flap than the paste applications at the under side.

The spaces I between the cement applications at the outer side of the flap are provided so that when the roll is contacted by the belts 59, which latter are first caused to travel so as to revolve the roll up to press speed, the belts will engage the roll at said spaces and between the cement applications so that cement willv not be transferred to those belts.

After the joint of the new roll web with that of the expiring roll web, the belts will be stopped of the fresh revolving roll.

the next step is to start the revolution of the fresh roll by driving the belts 59.

In the present instance, this is effected by actuating the clutch 15 so as to begin driving shaft 62 and the shaft 49 so as to drive the belts. The belts then being in contact with the fresh roll will drive the latter until it. is up to press speed.

The next step is to bring the running expiring web into contact with the cement-coated flap |09 This is effected by means which will now be explained, 'reference and 1l.

On one end of each spindle 29 there is a grooved circular head H2 at whose inner side there is provided a cam H3. The cam therefore revolves with the web roll, and, as shown in Fig. 10, has position at the outer side of the deckf arms 21 in which the bearing 35 for the spindle is formed.

`At the front forward edge of the vertical end bar 25 of the press frame there is sustained a vertical bar H4 whose lower end is square in crosssection so that the same will be held in its guide brackets H5 against turning. To the lower end of this vertical bar I |4 there is attached a bracket HB which carries a solenoid H1. This solenoid has a core on one end of which there is acircular head H9 so that when the solenoid is energized the head H9 will be projected outwardly in the path of the cam H3 on the head.

As, the solenoid and its head are both carried on the bracket H5 and the latter is attached to the lower end of the vertical bar H4, when vthe head H is projected in the path of the cam H3 it will be engaged by that cam and pushed downwardly as the cam turns, thus depressing the vertical bar H4. A

The vertical bar |4 (see Fig. 5) is surrounded by a coiled spring H9 which normally holds the bar up, but which will compress when the bar is moved down.

The upper end of the vertical bar H4 carries a bracket-plate |20 which has a horizontal tripportion |2| and a vertical portion whose lower end carries a yielding trip-finger |22.

Below the trip-finger |22 there is a horizontal brush-shaft 23 which extends across the press between the deck-arms 21,-and one end of this shaft carries a lever-arm |24 which latter is provided with a slot |25 through which the vertical bar H4 extends. A semicircular loose head |29 is carried on the vertical bar H4 and this head seats against the upper side of the lever-arm |24 around the slot, while a coiled spring |21 encircles the bar and has its lower end seated on the upper side of the same circular head |29. The upper end of said spring seats beneath the bracket plate |20. The spring |21 therefore exerts a constant downward push on the loose head |25 and tends to swing the lever-arm |24 downwardly. 1 The outer free end of the lever-arm |24 is provided with ya laterally-,projecting hand lug |29 and this lug, when the bar H4 is raised, is engaged by the lower hook-end |29 of a depending lever |30 and thereby held up against the action of thel spring |21 and thus holds the brush-shaft |23 against turning. f

Thus it will be seen that when the vertical bar H4 is depressed by the 'cam H3 engaging the head H9 of the solenoid, the trip portion |2| of the bracket-plate will engage the cam face |32 at the upper end of the depending lever and swing the hook-end |29 from beneath the hand-lug |29 of the lever-arm |24 and allow the spring |21 to depress said arm thereby causing the brush-shaft |23 to be rocked.

On the brush-shaft |23 there are two spaced apart arms |33 the swinging ends of which sustain between them a web depressing dev ice, which in this instance is a brush |34. A This brush extends horizontally across the press, directly over fthe running web |35 of the expiring roll, and also over the fresh roll which has been put in place, as shown in Figs. 1-23-24and 25. It will be noted that the running web is guided in its travel by idler rolls |35 and |31 and the web-depressing device is located in front of idler roll |39.

From the above explanation, it will be understood that when solenoid H1 is energized, such as by closing a circuit at push-button switch |39 (see Fig. the head H9 on the solenoid-core will move outwardly and be engaged by the cam H3 on the side of the spindle-head H2, whereupon, vertical bar |4 will be. depressed, latch |30 wm release levr-arm |24 and ausw brush-shaft |23 to rock. As shaft |23 rocks, arms |33, carrying the web-depressing device, in this 'case the brush |34, will swing down and lower the brush against the upper side of the traveling exhausting web |35, thereby depressinglthe latter into contact with the revolving fresh roll, as shown in Fig. 2`4`-,\so that when the cement-coated flap |09 of the fresh roll passes under the brush said flap will be cemented to the running web and be carried forward with the latter into the press.

The only remaining thing to be done to complete th union of the fresh web with that of the expiring web is to sever the running web from the expiring core, and this will now be explained.

By reference to Fig. 5, it will be noted that the push-button switch |39 is provided with a tripnger |39 which latter is pivoted thereto in such manner that it may be swung up from its pivot |40. AA lug |4|, formed integrally with the tripfinger, strikes against the rear face of the bracketarm |42 which limits the downward swing of said trip-finger.

Depending from the box of the push-button switch is a stem |43 which is movable upwardly from the position shown in Fig. 5, to cut off the circuit that is formed when the button |39 is pushed in and the lower end of this stem, when the circuit has been closed, terminates just over the free end of the trip-finger |39.

On the vertical bar H4 there is carried a laterally-projecting arm |44 with a trip-pawl |45 at its projecting end.

A The position of the pawl |45 with respect to the end of the trip-linger |39 is such that when the vertical bar H4.is depressed, carrying the arm |44 and pawl |45 with it, the pawl |45 will strike the end of the trip-linger when passing downwardly, but as the pawl |45 is pivoted to the arm, it will simply swing up and pass over said tripfinger end.

On the return,

or up stroke of the vertical barv H4 however, the pawl |45 will engage under the free end of the trip-linger and lift the latter so as to cause it to swing up under the stem |43 and move the latter up. 'Ihis upward movement of the stem |43 will break the circuit to the solenoid |1.and allow the head ||8 to withdraw from the path of the cam ||3.

When the vertical bar ||4 is depressed, coiled spring ||9 is compressed so that when the cam ||3 rides off from the head ||8 the vertical bar will at once begin its return or up stroke. During this up-stroke, pawl |45 actuates trip-finger |39 and stem |43 and cuts off the current to the solenoid |1 and retracts thevcore and the head I8.

Another operation results upon the return or up stroke of the vertical bar ||4, and that is the tripping of the cutter-blade |46. This is effected by means which will now be explained, reference being made particularly to Figs. 5-7-8-9 and 14.

A short horizontal shaft |41 is sustained in suitable brackets |48 and the outer end of this shaft is provided with a tripping-head |49. the vertical bar ||4 is in the elevated position, as shown in Fig. 5, the tripping-head |49 is slightly below, but in the path of the yielding trip-nger |22 which latter is carried at the lower end of the vertically-movable bracket-plate |20.

As the bar |4 moves downwardly, this trippingfinger |22 will yield as it passes over and under the tripping-head |49 on the outer end of the shaft |41, but when the bar ||4 returns, said tripping-nger |22 will engage under the trippinghead |43 and swing the same upwardly, thereby rocking the shaft |41.

It is to the shaft |54 that the knife or cutterblade |46 is attached, so that as the shaft |41 is rocked by the up-stroke of the tripping-finger |22, the crank-head |50 will be swung downwardly and toward the rear, thus pulling connecting bar |5| rearwardly and, swinging arm |52 so as to rock the knife-shaft |54 and thereby swing the cutting edge of the knife downwardly against the running expiring web |35 and severing the latter just forward of the joint of the flap |08 of the fresh roll to the running expiring roll, as shown in Fig. 25.

The circular drum |53 contains a coiled spring |55 (see Fig. 9) which serves to return the knifeshaft and knife to the normal position, a stop pin |51 serving to limit such return movement.

In order to promptly stop rotation of the running roll 29 and the spindle 28 on which the same is mounted, in case of breakage of the running web, or for any other reason, there is provided an emergency brake to coact with the circular head ||2 which latter is permanently attached to one end of said spindle.

This mechanism therefore, now to be explained, is best illustrated in Fig. 5.

Carried at the outer side of the vertical end bar 26 of the press frame is a vertical bracket |58 having upper and lower horizontal pins |59 and |60 respectively.

When

On the lower pin |60 there is mounted a head |6| having an arm |52 extending rearwardly therefrom which latter pivotally connects to the lower end of a core |63 of a solenoid |84. The wires connecting this solenoid include in their circuit a push-button switch (not shown) but commonly located within ready reach of an attendant at the control station, and usually termed the red button.

At one side of the head |5| there is a second head |55 which has a cam face |65 across its upper side.

From the second head 65 there extends a lower lever |61 which projects forwardly under the grooved head 2. The forward end of this lever |51 pivotally engages the lower end of an adjustable hook-bar |68,-the upper end of which bar carries a hook |69 which detachably connects with a pin or lug |10 that projects from the forward end of an upper lever |1|. The rear end o1' this upper lever is pivotally connected to the upper horizontal pin |59 of the vertical bracket |58.

This upper lever |1| pivotally carries a brakeshoe |12 which nts into the groove of the circular head ||2 that is carried on the end of the roll spindle 28.

A brake-shoe |15 is pivotally connected to the supplemental lever bar |13 which shoe enters the llolvger portion of the groove of the circular head From the above explanation it is believed to be clear that when the so-called red button is pushed, a circuit will be closed through the solenoid |64 and core |63 thereof will be drawn upwardly, thereby lifting the outer end of arm |62 and rocking heads |6| and |65. As these heads are rocked, the forward end of lower lever |61 will be swung down, pulling hook-bar |68 down with it, and thereby drawing down on the forward end of upper lever |1| and seating the upper brake-shoe |12 in the groove of spindle head ||2.

'I'hus the movement of the solenoid core |63 will clamp the circular head ||2 between the two brake shoes |12 and 15 and by frictional contact therewith will stop rotation of the head ||2, the spindle 28 and the roll 29 mounted thereon.
