APPARATUS FR CONVEYING AND BUN- 12 Claims.

This invention relates to new and useful improvements in apparatus for conveying and bundling newspapers and the like.

One of the principal objects of my invention is the provision of automatic means to receive folded newspapers from a printing press and deliver them in stacks of a predetermined number to a bundling device.

Another important object of my invention is the provision of automatic means for receiving stacks of newspapers and fashioning them into compact bundles for their' subsequent delivery from the bundling device.

In the newspaper printing art at present, the folded newspapers are deposited by the press upon conveyors which carry them to tables! where they are manually wrapped, tied into bundles and labeled for further dispatch. When the papers are deposited upon the conveyors,

, cam means are utilized to vdis-arrange or misaline one of the newspapers. Each mis-alined paper is indicative that a certain number of newspapers are deposited between it and the next preceding mis-alined newspaper, usually fifty papers.

It is one purpose of this invention to provide means for placing the newspapers from the delivery fan of the printing press, in a stack upon the conveying mechanism. I utilize the cam means above referred to to trip the actuating mechanism of the conveyor tol advance the accumulated stack and receive the following newspapers in a subsequent stack. As the stacks are advanced, they are finally positioned beneath the binding mechanism. The latter now surrounds the stack of newspapers with a single strand of wire, the adjoining ends of which are united and severed from the supply source. Following the severing of the wire strand, the completed bundle of newspapers is delivered from the bundling mechanism, ready for shipment.

Other important and incidental objects of my invention will be brought out in the following r specification and particularly se-t forth in the subjoined claims.

in the accompanying drawings illustrating my invention, Figure l is a side view of the newspaper conveyor and bundling mechanism. Figure 2 is a View of the receiving end of the device. Figure 3 is a view of the delivery end of the same. Figure 4 is a longitudinal sectional View taken on the line ,'i-l of Figure 3. Figure 5 is a detail view of the wire severing mechanism.

Figure l0 is a. detail view of the cam actuated mechanism for twisting and severing the binding wire. Figure ll is a detail view of the cam actuated means for advancing the conveyor mechanism step by step. And Figure l2 is a sectional view of the rear end of the shuttle tube, on the line I2-l2 of Figure l.

Referring to the accompanying drawings for a detailed description of my invention, the numeral I designates a gear side frame having a. top horizontal member 2, a bottom horizontal member 3, a front vertical member 4 and a rear vertcal member 5. (See Fgure l.) Opposite the frame i is a similar frame E that is joined with the former by cross supports 'l positioned intermediate the ends of the side frames.

Journaled in the front vertical members 4 of the side frames isV a conveyor belt drive shaft 8 to which are keyed spaced, conveyor belt sprockets 9, 9. The rear vertical members 5 carry another shaft It upon which rear conveyor belt sprockets Il, II are keyed. Passing around each pair of alined sprockets 9 and II is an endless conveyor chain I2. Now, when the shaft is rotated. these chains I2 will advance simultaneously.

Secured to the outer face of each chain I2 are spaced leading stack fingers I3. Each of these fingers is formed Vwith Va forwardly curved outer end lll, carrying a barbed'finger I5. Spaced rearwardrof the stack'iinger i3 is another stack linger iS, shorter-than the nger I3 and spaced suciently from it to receive between the spaced fingers a folded newspaper. The respective fingers I5 and I3 are spaced closely together in order to provide the maximum number of stack spaces upon the chain.

octagonal discs 2l to whose at sides blades 22 are secured. iVhen the press is in operation, the fan 2li will be operated in synchronism with the press and the folded edges of the newspapers will be received between the blades 22 and against the discs 2l.

The fan being rotated clockwise as Viewed in Figure l, the newspapers carried thereby will be engaged by the diverter fingers I9, which will force them from the fan and stack a required number of them upon the conveyor between the fingers i3 and l5. The method of advancing the conveyor chains, after a pre-determined number of newspapers have been deposited thereon, will now be described.

As previously described, a cam is utilized to misaline one of the newspapers as it is deposited upon the conventional conveyor mechanism. This is accomplished by a depression in the periphery of the cam, which, for each revolution of the latter, causes a cam follower to momentarily engage that newspaper passing beneath it to mis-aline it.

Referring now to Figure l, I have shown this cam, which will be designated 23, positioned near the fan 2%) and rotatable upon a shaft 24. Instead of the method previously employed, I have utilized this cam to actuate'a drive mechanism for advancing the conveyor chains.

Secured to the end of the shaft 3 adjacent the outer face of the frame l, is a four-toothed gear 25 of a conventional Geneva type. Positioned below the gear 25 is a pin disc 23 and lock plate 27 forming part of the Geneva gear system. Secured to the inner face of the lock plate 2".' is a pinion 28. This pinion, disc 26 and plate 2'! are keyed together for rotation upon a stub shaft 29 secured to the side frame l.

Below the shaft 2S is another stub shaft 3G, one end of which is journalled in the frame l and its outer end in an outboard bearing 3l. Keyed to the shaft 3] is a large gear 32 that meshes with the pinion 28. Keyed to the outer end of the shaft 3G, adjacent the bearing 3l, is a drive plate 33.

The plate 33 has formed therein, adjacent its periphery, a square hole 34 parallel with the axis of the shaft 33. Positioned within the hole 34 and slidable therein is a dog 35 whose outer face has formed therein a square recess 33. (See Figures 2 and 1l.)

Secured to the inner face of the bearing 3l is a cam plate 3'! having upon its periphery a spiral cam 38. This spiral cam 33 is adapted to enter the recess 35 when the plate 33 is rotated, as will presently be described. (See Figure l1.) Freely mounted upon the shaft 39 is a sprocket 39 having a long hub extension @9. This sprocket is rotated by a drive chain lill from a like sprocket i2 secured upon a main drive shaft 43 positioned at the rear end of the machine and later to be described.

The sprocket 39 has formed in its web adjacent its periphery, a square hole 44 which, when it is rotated, will be brought into alinement with the recess 36. Now there is provided on the outboard bearing 3l spaced lugs 45, between which there is pivotally mounted a pawl M5. Secured to the outer end of this pawl 4G is a link member lll whose upper end is pivotally connected to one end of a lever` arm 48. (See Figures l, 2 and 11.)

The lever arm 48 is pinned to one end of a short shaft G9 journalled in` a rearward extension of the frame l. Secured to the opposite end of the shaft 49 is a cam follower arm 53 whose outer tation of both shuttles.

end is in contact with the cam 23. When the cam 23 revolves, the cam follower arm 5U will rise as it enters the cam depression 23e, and the pawl 46 will force the dog 35 into the recess 44 and the recess 36 will be engaged by the spiral cam 38.

Upon the continued rotation of the sprocket 39, the dog 35 will bey withdrawn from the recess 44 at the completion of a single revolution of the plate 33. During the single revolution of this plate 33 and the gear 32 connected with it, thc Geneva gear mechanism consisting of the gear 25, disc 26 and plate 2?, will cause the sprockets 9, 9 to make a quarter revolution. This quarter revolution will advance the conveyor chains sufciently and accurately to position the succeeding stack ngers beneath the delivery fan, and the preceding stack of newspapers beneath the binding head, which will presently be described.

Formed rearward of the rear vertical members l 5 of the side frames l and 6, are short frame structures 5| and 5ta, in whose rearward vertical struts 52 the main drive shaft 43 is journalled. Secured to the shaft 43 is a conventional clutch mechanism 53 manually operated by a lever arm 5e.

Attached to the free side of the clutch -53 is a sprocket 55 which is adapted to be driven by a sprocket chain 53 from an electric motor 5l. (See Figure l.) It is the purpose of this motor drive to complete the binding of the newspapers upon the conveyor when the press is not in operation.

Also secured to the shaft 43 is another clutch mechanism 58 of the positive drive type. The free side of this clutch has secured thereto a sprocket 59 to receive a chain 63, (see Figure 3). This chain also passes around another sprocket 6i on the shaft 24 for the cam 23. (See Figure l.)

Normally the conveyor and binder are driven from the cam shaft 2li in order that all of the operations thereof will be maintained in a correctly timed relation with the press, the latter operating at varying speeds dependent upon the size of the edition of the newspaper being run.

Before describing the various intermittent drives for the bundling device, the various operations thereof will be described.

Coincdent with the positioning of a stack of papers to be bound beneath the binder, the feed shuttle advances a strand of wire to the opposite side of the binding yoke to be held by a gripping and releasing device on said opposite side, the feed shuttle being withdrawn. The yoke is now drawn downward, straddling the stack of newspapers and drawing additional wire through the feed collet to encompass three sides of the stack. When the yoke is held down, the opposite side of the shuttle will advance to grip the end of the wire strand held in the forward side of the binding head and draw it rearwardly beneath the stack of newspapers.

As soon as the retrieving shuttle is fully withdrawn, the free end of the wire, gripped in the retrieving shuttle, and the wire in the feeding collet are twisted together by a simultaneous ro- After the strands are twisted together, the ends are severed and the binding head raised. With the raising of the binding head, the conveyor belt is advanced to discharge the bound newspapers and position a succeeding stack beneath the binding head.

Each of the rear vertical supports 5 of the side frames l and 6 projects above the top members 2, and has formed therein an elongated slideway |52 for a cross head 93. At each side the cross head 63, where it is supported within the slideway, is formed with a depending flange 64 joined by a transverse rib 65 with the center of the cross head. Above the cross head proper the side flanges are formed rearwardly to provide bearings 69, 66 for the shuttle actuating shafts 61 and 68.

Below the bearings 66, 98, and between the side frames I and 6, there is provided a rearwardly extending bearing 69 integral with the cross head and adjacent the side frame l, for a short hori- Zontal shaft 99a. Adjacent the side frame 6 is a similar bearing 10 for another short horizontal shaft 10a. Immediately below the bearing 99, and likewise integral with the cross head, is another bearing 1| for a vertical shaft 12. Also below the bearing 10 is a bearing 13 foranother vertical shaft 14 adjacent the side frame 6.

On the rear side of the machine the cross head 63 has projecting therefrom a short stud 15 that receives thereon a link 10. The lower end of the link 18 is pivotally connected to the free end of a crank 11 that is rotatable with a shaft 18 to which it is keyed. The shaft 18 is journalled in the rear vertical member of the side frame I, and has secured thereto a gear 19 by which the shaft is rotated through means later to be described,

When the shaft is rotated to bring the crank- 11 to the position shown in Figure 1, the cross head 63 will be raised, and when the shaft is rotated 180 degrees the cross head will be lowered.

The cross head and shuttle mechanism will now be described. At the center of the cross head 63 I have provided a cylindrical boss 80, bored out toy receive therein the hub extension 8| of a worm gear 82. The hub is maintained within the boss 80 by a retainer collar 83 secured to the rear end thereof. (See Figure 6.)

The hub extension 8| of the gear 82 is machined to receive therein the forward end of a shuttle tube 8f3, that does not extend entirely through the hub. In front of the end of the tube 8, the hub 8| is counterbored and formed with square serrations S5. Slidably positioned within the shuttle tube 813 is a semi-circular feed shuttle 86 and a semi-circular retrieving shuttle 81. The shuttles 8B and 81 at their forward ends are provided with semi-circular serrated flanges 382L and 81a which, when the respective shuttles are fully withdrawn, will be received within the serrations 85.

The semi-circular feed shuttle 03 has therein an axial passage 88, which, adjacent the front end of the former, terminates in a short tapering bore 89 and a smaller straight bore 90. Positioned within the bore 90 is a feed collet 9|, whose outer end projects slightly beyond the face of the shuttle. At its rear end the collet is formed with a tapering head portion 92 which is slotted in a conventional manner to render it yieldable when forced into the tapering bore 99.

Extending axially of the collet is a passage for the binding wire that projects forwardly through the shuttle, and a slidable tube 99 positioned in the passage 88 rearward of the shuttle.

The rear end of the shuttle tube 84 is secured within a sleeve 94. Extending rearwardly from this sleeve are parallel flanges 95, 95 between which spring tensioned jaws 99, 96 are positioned. rIhe purpose of these jaws 99, 96 is to permit the free withdrawal of the binding wire and at the same time to prevent the retroactive movement of (See Figstrike the jaws 96, 99 and force the collet 9| forwardly into the tapering bore 89 to lock the wire therein.

The retrieving shuttle 81 has in its forward end a square recess 91, rectangular in cross section and whose opposite narrow faces 91a, 91a are tapered rearwardly. Extending from the bottom of the recess 91 tothe rear end of the shuttle is an aperture in which is positioned a slidable rod 98. (See Figure 7.)

Positioned within the recess 91 is a pair of hinged, spring tensioned jaws 99, whose opposite faces bear against the tapering faces 91a, 91'a of the retrieving shuttle. Now, when the shuttle reaches its rear-most position, the rod 98 will V'be forced forwardly to force the jaws. out of the tapering recess 91, whereupon they will remain open.

Each of the shuttles 86 and 81, adjacent its rearward end, has formed in its semi-circular pe riphery a groove or recess |00, which, when the shuttles are fully withdrawn into the tube 84, forms a continuous circular recess. Positioned in each recess |00 is a semi-circular yoke |0| having at its center an outwardly projecting radial stud |02. (See Figure 12.) Each of the studs |02 is slidable in an elongated slot |03 in the opposite side Walls of the shuttle tube 84. When these studs |02 are moved axially of the tube 84, a respective shuttle will be projected, and when 'the shuttles are fully withdrawn into the tube 84, their rotation is possible by virtue of the alined recesses |00-`-||l0. Extending upwardly from the sleeve 94 are spaced arms |94, |04 upon which a supply of binding wire |04a is supported.

Secured to the cross head 03, and extending upwardly from the boss 80, is an invertedA U shaped binder yoke |05, preferably of channel shape in cross section and reinforced with web plates |06, secured to the side flanges of the' yoke proper. In the forward depending end of the yoke, I have provided an aperture |01 behind which there is positioned a chuck mechanism |08 to receive and hold the end of the wire strand as it is delivered by the feed shuttle 86. This chuck mechanism |08 consists ofa pair of wide jaws |09 and 0, positioned horizontally and in substantial alinement with the feed shutthe collet. (See Figure 9.) l

The jaw |09, which functions as a release jaw, is positioned within a rectangular recess l and at a slight angle with the axis of the shuttle. At its inner end the recess terminatesV in a larger aperture ||2 in which a strong spring ||3 acts to force the jaw out of its inclined recess toward and into engagement with its companion jaw I0. The jaw ||0, which is slightly longer than, and extends beyond, the jaw |09, is also received within a rectangular recess I4. This recess is also inclined, with respect to the recess and at suchv an angle that, when the jaw ||0 is forced into its recess, it will co-act with the jaw |09 to firmly gripthe strand of wire. Like `the recess the recess ||4 terminates in a larger aperture, H42, in which another spring l5, lighter than the spring |3, tends to force the jaw ||0 out of its inclined recess and out of engagement with the jaw |09.

The angle of the recesses receiving the jaws is such however, that, after the jaw ||0 is forced into its recess, it will not be forced out by. the

spring ||5 until the jaw |09 is forced into its recess, due to their Wedge action.

Projecting from the face of the release jaw |09 is a finger ||6 which, when the retrieving shuttle advances to pick up the end of the wire, will be engaged by the end of the shuttle and force the release jaw inwardly, to release the wire. (See Figure 9.) However, when the feed shuttle advances to deliver the wire strand to the jaws |69 and H6, the nose of the collet 9| will strike the face of the jaw ll, forcing it inwardly into engagement with the jaw |99 and at the saine time releasing the collet from its tapered seat.

The means for alining the feed and retrieving shuttles with the chuck mechanism for their successive operations will be described later.

The twisting and shearing mechanisms will now be described. Formed on the forward face of the cross head 63, at one side of the boss 88, is a similar boss I1 to the center of which there is secured by a shouldered stud I8, a worm gear H9 of the same diameter as the gear 82. Secured to the outer face of the gear ||9 are two single lobe peripheral cams |26, |26 with their respective lobes spaced degrees apart and adapted to be rotated by the gear H9. (See Figure 5.) Adjacent the gear H9, and in alinement with the gears I9 and B2, is another shouldered stud |2I, upon which there is pivotally mounted the ends of oppositely disposed curved shear blades |22, |22. The opposite faces of the shear blades are beveled in the customary manner to provide a cutting edge for the wire strands after they are twisted together.

Adjacent its mean point, each of the blades is formed with a cam follower |23 adapted to engage its respective cam. Surrounding the stud |2| is a coiled spring |24 whose free ends |25, |25 engage the outer edges of the blades |22, |22 to force them together to shear the wire when simultaneously released by the cams |26, |26.

Formed on the cross head 63, and positioned above each of the gears 82 and H9, are spaced bearings |26, |26 and |21, |21. Mounted upon a cross shaft |28 journalled in these bearings |26, |26 and |21, |21, and positioned between the bearings |26, |26, is a quadruple thread worm |29 in mesh with the worm gear 62; and between the bearings |21, |21, a single thread worm |36 in mesh with the worm gear H6. Accordingly, when the shaft |28 is rotated, the gear 62 will make four revolutions while the gear ||9 makes one revolution. It is thus evident that the strands of wire forming the binding tie will be rmly twisted together before the cams |20, |26 are rotated suniciently to sever them. (See Figures 5, 6 and '1.)

The method of actuating the shuttles will now be described. Freely mounted on the projecting ends of the studs |62 of the yokes |6| in the shuttle tube 84, are links |3|, |3| Whose forward ends are pivotally connected to the outer ends of lever arms |32, |32. (See Figure 1.) One of these lever arms for the feed shuttle 86 is secured to the inner end of the shaft 61, while the other lever arm |32 for the retrieving shuttle 81 is secured to the inner end of the shaft 68.

Secured to the outer endof the shaft 61 is another lever arm |33 to whose free end a link |34 is pivotally connected. Attached to the outer end of the shaft 69a is a lever arm |35, shorter than the lever arm |33 and to Which the link |34 is pivotally connected. To the inner end of the shaft 69a there is keyed a bevel gear |36 adapted to be driven by a bevel pinion |31 whose hub extension is rotatably mounted within the bearing 1|. Slidably mounted within the hub of the pinion |31 is the upper end of the vertical shaft 12. This shaft is formed with a keyway |38 extending the full length thereof and adapted to permit the sliding of the pinion |31 thereon when the cross head 63 is raised or lowered.

On the inner face of the frame structure 5| I have provided a bearing |38a for the lower end of the shaft 12, and to the latter, immediately above the bearing, there is secured a spiral gear |40 adapted to be driven by another spiral gear |39 keyed to a horizontal shaft |4|. This shaft |4| is journalled in bearings |42, |42 formed on the inner face of the frame structure 5|. Attached to the rear end of the shaft |4| is a bevel pinion |43 driven by a bevel gear |44 attached to a four-toothed gear |45 of another Geneva gear drive. The gears |44 and |45 are freely mounted for rotation on a short stub shaft |46 secured to the rear vertical strut 52.

Secured to the outer end of the shaft 68 is a lever arm |41 to whose free end a link |48 is pivotally connected. Attached to the outer end of the shaft 1|a is a lever arm |49, shorter than the lever arm |41 and to which the link |48 is pivotally connected.

To the inner end of the shaft 16a there is keyed a bevel gear |56 that is adapted to be driven by a bevel pinion |56a whose hub extension is mounted in the bearing 13. Slidably mounted within the hub of the pinion |50a is the upper end of the vertical shaft 14. This shaft, like the shaft 12, is formed with a keyway |5| extending the full length thereof and adapted to permit the sliding of the pinion |56n thereon when the cross head 63 is raised or lowered.

On the inner face of the frame structure 5|a a bearing |52 is provided for the lower end of the shaft 14, and to the latter, immediately above the bearing, there is secured a spiral gear |53 adapted to be driven by another spiral gear |54 keyed to a horizontal shaft |55. This shaft |55 is journalled in bearings |56, |56 formed on the inner face of the rear frame structure 5|a. Attached to the rear end of the shaft |55 is a bevel pinion |58 driven by a bevel gear |59 attached to a four-toothed gear |66 of another Geneva gear train |6|. The gears |59 and |66 are freely mounted for rotation on a short shaft |62 secured to the rear vertical strut 52 of the structure Ela.

'Ihe shafts 61 and 68 are intended to be alternately oscillated to advance and return the feed shuttle rst, and then, after the descent of the binding head, to advance and return the retrieving shuttle. These operations are in definite timed relation, not only with each other but also with respect to the shaft 18 by which the cross head or binding head is raised and lowered. This synchronized drive will now be described.

Keyed to the drive shaft 43 adjacent the frame I is a largegear |63 that is adapted to drive a smaller gear |64 above it. The gear |64 is secured to the inner end 'of a short horizontal shaft |65 whose inner end is journalled in an inboard bearing |66 and its outer end in the frame structure 5| below the shaft |46.

Also mounted upon the shaft |65, adjacent the gear |64, is a pin disc |61 adapted to drive the four-toothed gear |45 when the pin |68 of the disc |61 engages one of said teeth. Secured to the face of the disc |61 is alock plate |69 whose periphery will enter one Vof the arcuate recesses in the gear |45, to lock the latter against rotation when disengaged by the pin |88. This mechanism constitutes a typical Geneva gear drive, and for each complete revolution of the shaft |65, the gear will make o-ne quarter of a revolution, and through the gears |93 and |99, |39 and |49, |36 and |31 the feed shuttle 86 will be projected across the binding head to deposit the strand of binding wire in the gripper mechanism and return to its starting position. Immediately following the operation of the feed shuttle mechanism, the binding head is lowered tostraddle the stack of newspapers to be bound, and as it descends, additional Wire is drawn through the feed collet to encompass three sides of the stack.

The mechanism for raising and lowering the binding head in timed relation with the shuttles will now be described. Meshing with the gear 19 is a larger gear |19 to whose outer face there is secured another four-toothed gear |1| of a Geneva gear drive |12.

Secured to the outer end of the shaft |65 is another pin disc |13 keyed tothe shaft in fixed relationV with the disc |81. Also attached to the inner face of the disc |13 is another lock plate |14 whose periphery will enter one of the arcuate recesses between the teeth in the gear |1| when the latter is disengaged by one of two diametrically opposite pins |15 and |16 carried by the disc |13.

As shown in Figure 1, the shaft |65 rotates counter-clockwise, and as soo-n as the pin |68 leaves the gear |95, the pin |15 carried by the disc |13 will engage one of the teeth of the gear |1| to impart a one-quarter revolution to it. Then, through the gears 19 and |19, the binding head will be lowered over the stack of newspapers to be bound. Immediately following the lowering of the binding head, the retrieving shuttle 81 will be projected to pick up the strand of wire held in the. gripper mechanism |08.

The projection of the retrieving shuttle is accomplished in the following manner. Keyed to the shaft 43, adjacent the frame 6, is a large gear |11 similar to the gear |63 and adapted to drive a smaller gear |18, like-the gear |69. The gear |18 is keyed to a shaft |19 whose inner end is journalled in an inboard bearing |89 and its outer end in the frame structure 5|@ below-the shaft |62. Keyedto the shaft |19, adjacent the outer face of the gear |18, is a pin disc |8| in Xed relation with the pin discs |61 and |13. Also attached to the outer faceof the disc |8| is a lock plate |82 whose periphery will enter one of the arcuate recesses between the teeth of the gear |89, when the latter is disengaged by a drive pin |83 carried by the disc |8|, the gear |69, disc |8| Yand plate |82 constituting the Geneva gear train |6| previously referred to. Y j When the pin |15 leaves vthe gear |1|, the pin |83 will engage one of the teeth of the gear |69 to turn it one-quarter of a revolution; and through the gears |58 and |59, |53 and |54 and |49 and |59, the retrieving shuttle will be projected to pick up the wire strand and return it to its starting position.

The ends vof the wire strand are now ready to be twisted together, as previously described, by the rotation of the shaft |28, followed by a severing of the twisted strands. Secured to the outer end of the shaft |28 is a bevel pinion |89 adapted to be driven by a bevel gear |85, slidably keyed to the upper end of a vertical shaft |86. The hub Y (See Figure 10.)

extension |81 of the gear |85 is journalled in a bearing |88 integral with the cross head 63.

To the lower end of the shaft 86 I have secured a spiral gear |99 adapted to be driven by another spiral gear |9| at right angles with it and keyed to the forward end of a horizontal shaft |92. The shaft |92 is journalled in bearings |93, |93 provided on the inner Vface of the frame structure 5| a.

Attached to the rear end of the shaft |92 is a clutch disc |99 co-acting with another clutch disc 95 slidably keyed to the forward end of another shaft |96 in alinement with the shaft |92. The shaft |99, like the shaft |92, is supported in bearings formed on the inner face of the frame structure 5| a. Secured to the rear end of the shaft |96 is a beveled pinion |91 adapted to be continuously rotated by a bevel gear |91a keyed to the inner end of the shaft |19.

The clutch discs |94 and |95 are normally held disengaged; but following the return of the retrieving shuttle 81 to its starting position, theseY discs are momentarily brought. into driving engagement for a sufficient time to rotate the shuttles four revolutions toV sever the vtwisted strands, as previously described. 'Ihis engagement of the clutch discs is effected inthe following manner.

Formed on the hub extension of the disc |95 is an annular Vrecess |98 that receives therein the lower forked end of a lever arm 299. Integral with the upper pivoted end of the arm 299 is a cam follower arm 29| adapted to bear against the periphery of the pin disc |8|. VNow, following the disengagement of the pin |83 carried by the disc |8| from the gear |69, the cam follower will enter a depression 292 in the periphery of the disc and cause the clutch discs |99 and |95 to be brought into driving engagement.

In order to effect a proper alinement of the feed shuttle with the gripper mechanism when the binding head is raised, and the retrieving shuttle with the gripper mechanism when the binding head is lowered, I have provided a spiral rib 293 surrounding the vertical shaft |86. Therefore, when the binding head is lowered, the spiral rib 293 will engage a projection 299v on the frame 6 to rotate the shaft |86 sufficiently to transpose the position of the feed shuttle and the retrieving shuttle before the latter is projected. During the ascent of thebinding head, the rib 293 carried by the shaft |86 will again cause the latter to be rotated sufficiently from the stopping position of the shaft |86 when the clutch is disengaged, to the position shown in Figure 5.

When the wrapped newspapers are discharged, they are deposited upon a table extension 295, eX- tending rearward of the machine and supported by legs 296.

The means for applying a protective wrapping for the newspaper bundles will now be described. ExtendingV transversely of the machine and journalled in the lower end of the front vertical members 4 ofthe frames and 8, is a cross shaft 291 having secured thereto a wide pulley or roller 298. Extending transversely of the rear of the machine and journalled in the lower end of the rear vertical supports 5 of the side. frames andl 6, is another cross shaft 299 having freely mounted thereon another wide pulley or roller 2H).V Y Movable around the pulleys 298 and 2|9 is a wide endless conveyor belt 2|| which, at the rear end of the machine, passes under a supporting plate 2|2 carried by the bottom side rails 3, 3.

Keyed to the shaft 291 is a gear 2 I3 that meshes with the gear 32. When the gear 32 is rotated, the gear 2|3 will cause the belt 2i! to move forwardly a predetermined distance.

rIhe plate 212 is adapted to support thereon a stack of discarded newspaper sheets whose overhanging portions are supported upon the belt 2l l. As the belt is advanced, the bottom sheet will be withdrawn by frictional contact with the belt and carried forwardly and deposited upon upwardly curving arms 2id, 2id. When the conveyor belts are advanced, the barbed stack ngers carried thereby will pick up the sheet of paper deposited upon the arms 2M, 2M and carry it forwardly to the stacking position below the fan. At this point the folded newspapers deposited therein will be encompassed by the wrapper and protected from damage by the subsequent handling of them.
