MECHANISM FOR .PAPER-ASSOCITING MACHINES.

Be it known 'that I, GLAUD' D. .'CURRY, of Memphis, in the county of Shelby' and State of'Tenne'ssee, have invented certain new and useful Improvement-s in Feeding Mechanism for Paper-Associating Machines; and I do hereby declare the lfollowing to be a full, clear,and exact description 'of vthe invention, such as will enable others skilled in the art to which it appertains to make and use thesame.v V

This invention relates to improvements in paper assgciating or stuffing machines, and more particularly to impoved'feeding mechanism'thereforf-the object of the invention being to provide simple and eiicient means for feeding paper sections successively from different. hoppers or sourcesof supply to mechanism which performs the work of stuing or inserting one paper section within another.

With this object in view, the invention consists in certain novel features of construction and' combinations of parts ashereinafter se forth and pointed out inthe claims.

In t-he accompanying drawings; Figure 1 is aA vertical transverse section, partly in elevation; of machine showingan embodiment of my invention;A F ig. 2 is a transverse vertical section througlf the cente of the machine, at right angles' to Fig. 1; Lig, 3- is a plan view with thehopp'ers removed; F ig.a l4 is an enlarged sectional view ofa portion of one of the cylinders andv needle box devices; Fig. 5 is an ,enlarged ,end view showing the cylinders and cooperating-devices; Fig. G is a perspective .View of one of the needle box constructions employed in the cylinders of the vfeeding mechanism; Fig. 7 is a plan View of one of the tumbling blades; Fig. S is an end view of the same, and' Fig..9 is a perspective view `showing one of the spring actuated lingers.

1 represents suitable frame-work, upon which'v twohoppers- 2 3- are located and these hopper-s are provided with' inclined Y bottoms 4 which extend partially across the lower ends of the same and terminate appreciable distances from the inner side walls of the hoppers. A vertical shaft 5 is mounted in the framework between the hoppers 2-3 and at its lower end, carries a horizontallydisposedvl disk 6. which projects partially across the open lower ends of both hoppers.

Specification of Letters Patent.

This disk is made with a curved taperingV slot or recess 7 extending inwardly from its peripheral portion and forming a taperingy finger 8. The upper end of the shaft 5 is provided with a bevel" gear 9 which receivesl motion from a bevel gear lOon a horizontal shaft 11, for continuously driving .the disk 6.

Below the disk 6 and at respective sides of the axis thereof, horizontally-disposed cylinders 12 and 13 are located.V Each cylinder is provided with a shaft 14, one end of which projects beyond the cylinder and -forms a journal mounted in a suitable bearing in the frame-work, and to the journal vof each shaft 14, a gea-r 15 is secured to receive motion from the driving mechanism. yThe inner end of the shaft 14 of each cylinder terminates Within the latter and is made with a socket 16 which receives the inner end of a short shaft 17 secured to the framework. The shaft 14 of each cylinder is thus journaled at one end in a bearing-on the framework and atv the other end, on the inner end of the fixed shaft 17.

. It may be here stated that the mechanisms vat respective sides of the vertical center of EissUEn the machine, are duplicates in construction I and mode of operation, but .the two sets of devices are arranged in reverse positions at ,respective sides of the vertical center of the machine.

peripheral wall near one end, with an opening 18 for the accommodation of a mechanical withdrawing device or needle box 19 as shown in Fig. 1. In constructing this withdrawing device o. needle box, I provide a rectangular frame 20 which embraces and slides on a block 21 secu red to the fixed sha ft section 17 so as to be guidedv in its longitudinal movements by said block. The frame 2O is provided at one end with an inclined enlargenient- 22, the outer face of which isdisposed at an angle of approximately 45O to the axis of the frame 20. To the inclined face of the enlargement 22, a skeleton head 23 is adjustably'secured. The outer member of the skeleton head 23 is disposed at right anglesv to the axis of the frame 20v and is provided' with a number of inclined perforationsl 24 for the 'passage of a number of pins or needles 25, lprojecting in an inclined direction from a series of fingers 26, 'which constitute the upper or outer 85 Each cylinder 12413, is provided in its A members of a movable head 27. A guide rod 28 projects from the lower or inner portion of the movable head 27 and moves freely in a socket 29 in the enlargement '22 of theframe 20. Levers 30 are pivotally supported l .between their ends, at diametrically opposite portions on the frame 20. The inwardly projecting arms of the levers carry pivotal 'blocks 31 mounted toA move in wa'ys 32 at ribs 34 to move in guide grooves 35 in said frame. It is apparent that if the cross headA 33 be vmoved on the frame 20, motion will be imparted, through the medium of the levers 30 to the movable head 27 for the purpose lof projecting or withdrawing the pins or needles For thus operatingthe cross head and for sliding the frame 201longitudinally, each cylinder (12 and 13) is provided at one end with two cam grooves 36' and 37, one within the other. A pin 38 projecting from the sliding frame 20 enters the larger outer cam groove 36 and a pin 39 projecting from the cross-head cooperates with the inner cam groove 37 'As' shown in Fig. 3 of the drawing the needle box, or withdrawing devices 19 above described, are located at one end of the cylinder 12 andat the opposite end of the cylinder 13. Hinged lingers 51 are located near the needle boxes or withdrawing devices 19 and are held up in engagement with the bottom paper sections in the hoppers, by the i peripheral portions of the disks 6. It. will be observed in Fig. 3 of the drawing, thatthe peripheral portion of the disk 6 is depressed fror'n the point `52 to the slotted portion of said disk. Jl/hen, during the rotation of the disk, thel depressed portion 52.

reaches .the finger 51, the latter will be free to drop a-nd it will be positively 'forced down by the action of a spring 53, so as to be out of the way of the needle box or withdrawingr device 19.

The cams 36 are so formed that they will cause the needle box 19 to be projected toward the lower ends of the hoppers 2 3 and subsequently withdraw them, and the cams 37 will so'coperate with the cross vheads 33 as to causethe needles 25 to be projected and afterward withdrawn. The camsh36-37 of the respective cylinders'are so disposed that the needle boxes or withdrawing devices in one cylinder (say the cylinder 12) will operate in advance-of these in the other cylinder; so that an outer part or section of sheets will be withdrawn from one hopper in advance of the withdrawal of an inner part or section from the other hopper. Thus the needle box in one end'of the cylinder 12 will be projected upwardly toward the foldn `caused to'ret-reat and thus to pull the corner ofthe folded paper section downwardly into the slot 7 of the horizontal disk The cam 37 in the cylinder will afterward operate to withdraw the .needles 25 from ,the paper section. The rotation of the disk 6 will first. cause its linger 8 to,pass over the paper section, and during the rotation of the disk, a portion thereof. will become disposed over aportion of the folded paper section. As the disk 6' turns, its linger portion 3 will engage the finger 51 which had been dropped and raise said finger to its normal horizontal position. During such raising of the finger 51, vany portion of a superimposed .paper section which may have descended with the lowermost paper section being fed from the hopper, will be raised andits entanglement with the disk G eifectually prevented.l The paper section having been pal'- tially removed from the'hopper, will now be .met by a tumbling blade 40 carried by the cylinder and deflected by said blade so as to be fed between the cylinder and a feed rol'ler 41. The cylinder isprovided with shoes 42 Aof leather or Yother suitable ma terial, which are so placed that they will arrive approximately opposite `the feed roller 41 after the paper section reaches the latter.

The cooperation of the shoes 42 on the cylinder with the feed roller 41, will cause the paper section to be fed downwardly and said paper section will be made to follow the cylinder by means of curved guides 43. After conforming to the contour of the cylinder throughout a portion of their length, the guides 43 project downwardly in a straight, diagonal direction and terminate adjacent to rollers 44 secured to a shaft 44 located at one side of the vertical axis of the machine. Rollers 44 are similarly located at the other side of the vertical axis of the machine and the guides 43 and feed roller 41 are also duplicated so as to cooperate in the same manner as above described with the cylinder 1 3 andthe paper sections removed in the same manner as previously explained from the hopper 3. Rollers 45 are located on shafts 46 adjacent to the cylinders 12 and 13. Feeding tapes 47, coperating with the respective cylinders 12 and 13, pass over the rollers 44 and 45 at respective sides of the vertical axisiof the machine and are driven by power applied to the shafts of the rollers 44. Shafts'48 arelocated above the rollers 44 and carry rollers 49, which cooperate with the tapes 47 to feed the paper section downfwardly over the rollers 44, Guides 50 are hung-onthe shafts 48 and extend from the longitudinal center'of the machine approximately to the cylinders 12a-nd 13, so as to cooperate with the tapes in directing the paper sections downwardly ers 44.

f Reverting now .to the tumblingfblade 40, fitsconstruction and mode of operation will befexplained: Each cylinder (12 and 13) is provided with an elongated. slot or opening, 58behind which a shaft 54 is located and provided with crank 'nals 56-57 mounted in the respective heads of Ythe cylinder. Onthe shaft 54, the blade 40. is .hinged and pressed in one direction against stops 59 on the shaft,vby means of springs 60.r It will be understood that each cylinder' is provided with a' tumbling blade and are duplicates in construction and mode of operation. Near one end of each cylinf framework prises a vertical portion "35 der, a ring G1 is located and provided at Adiametrically opposite points with recesses 62;(33.

A cross head G4 is located at the end of the journal 56 of each shaft 54 and from the respective ends of this cross head, pins 65 project into the ring (31. Gears 66--67 are mounted on suitable studs to the adjacent to the ring G1, and each of said gears is provided with a lug 68 disposed -within said ring 61. T-shaped track- 'ways @flare located adjacent tive ends of the cylinders, and each com- 70 located hetween the cylinders and lateral portions 71 projecting upwardly over. the cylinders. With these trackways, rollers 72 at .respective ends of the tumbling blades 40 cooperate as presently explained. During the passage ofthe tumbling blade 40 under the disk 6, it will be prevented from engagement with the latter, by the engagement of the rollers 72 with the upper members 71 of the trackway 69. When the blade, moving with cylinder, delects the paper section and causes it to be fed under the feed roller 41 as previously explained, one of the lugs 68 will engage one of the pins 65 on the shaft 54 and force the same into one of the recesses (652 or C3) in the ring G1. As the cylinder continues to turn, the engagement of one of the pins on the shaft l54 with the recess in the ring G1 will cause the shaft 54 and the blade 40 to be turned over. VVhem'during the rotation of the cylinder, the .tumbling blade reaches the other recess in the ring 61, one of the pins 65 will enter the other rei cess (62 or G55)A and the blade will again turn so as to place it in proper position to deflect the next paper section coming from the hopper. After the blade 40 has been thus turned, it will be prevented from engagement with -the'adjacent cylinder by the ridon the vertical ing of the pins or rollers 72 69,-the bladeportion '70 .of the trackway arms 55, having jourto the respecs collapsing or' being thus pressed back against the resistance ofthe sprinofs G0.

I have hereinbelfore described the construction and operation of the mechanism which will take a folded paper section from the inner paper section into the outer paper section. Before the inner paper section can bo inserted intovthe outer section, the latter must be opened -to the paper sections shall have been 'stuffed they must be discharged from the machine. For these purposes, the mechanism now to 'be described will be employed.

Some distance below the rollers 444, two shafts 73 are mounted in the framework and terminate at their inner ends at respective sides of the vertical' center of the machine. These shafts are provided at their inner ends with annular flanges 74 to which Vertically disposed disks 75 are secured, each of said disks being made with a curved slot forming a finger 77, and with a' depressed peripheral portion 78,'for apurpose hereinafter explained. Parallel `guide plates v79 are suitably supported by the framework and extend from therbllers 44, downwardly between the disks 7 5,-1- said guide plates terminating at their lower ends somewhat below the axes of the disks 75. Rollers 80 are mounted near the shafts 81 located in proximity to the guide plates 79. Tapes 82 pass over rollers 45 near one end -of each shaft 46 and, extending downwardly parallel with the tapes 47, ,pass over rollers 44 o n the shafts-44a; then downwardly and under the rollers 80, and finally back to the rollers 45 on shafts 46. Tapes 84 pass overl rollers at one end of each shaft 44a, and over rollers receive it, and afterv at one end of each shaft 81-said tapes 84 also passing over rollers 85 supported by brackets 80 secured to the framework.

A'paper section' is fed downwardly by the action of the tapes above described and after passing between and beyond the lower ends of the `uide plates 79, will rest on fingers 87 projecting' from a shaft 88 located below t-he vertical disks 7 5. Adjacent to the shaft 88, another shaft 89 is located, and to the shafts 88 and 89, the lower endsof guide strips 90 are secured, the upperf ends of said strips being' supported by transverse rods 91 located'short distances outwardly from the outer faces, of the disks 75.

Inl order to prevent the paper section from i crowdingupon itself by dropping too heavily upon the-lingers 87, I

Aprovide arms 92 pivotally supported at the.

lower' end on the shaft 88 and provided at their upper ends with fingers 98 adapted to cooperate with stops 94 supported by one of the rods 91. The arms 92 are provided with a shoulder 95 to be engaged by a cam.

provided with. guides 99a (Fig. 2) which support longitudinally movable arms 100 carrying needle boxes 101 at their innerends. Theseneedle boxesare-located nearthe front of/the machine'in proximity to the disks 75 and the depressed peripheral portions of these disks will permit said needle boxes to reach the upper front corners of a paper section resting between the disks.

The mechanism for operating the needle I boxes 101 is so timed and proportioned that v section.

the two needle boxes will be simultaneously moved toward each other and caused to confine t-he corner of the folded paper .section between them,-after which the needles will be projected and made tc engage the paper In order'to insure such engagement of the needles with the paper section so that when the needle boxes are withdrawn,

the corners of the folded paper section will be moved laterally,the devices now to be described will 'be employed.

brackets 129 secured'. to the framework and receive motion from gears 130, the shafts 13G secured to 'the fixed transverse bars 99.'

The paper section h'aving been'disposed between the disks 75 and made to rest with its folded lower edge-upon the fingers87, the needle boxes 101 willadvance to grasp the corner of the paper section between them land theneedles caused -to penetrate the members of the folded paper section, all as previously explained. The needle boxes will now beA retracted to canse the corners The journal bearings of gears 128` are supported by separate from each other, and afterward, the needles will be withdrawn from the paper. When the corners of the folded members of the paper section shall have been moved away from veach other, the nose or tingerportions 77 of the disks 75 will approach the separated corners of the paper section members and, as the shoulders 134 on said fingers 77pass over the rollers 135, said fingers will be depressed suficiently'tb cause them to enter between th members disks continue to rotate, they will become disposed on the inside of or between the members of the folded paper section, and thus said paper section'will be opened out and, supported by the'guide strips' 90, be in position to receive'an inner paper section between its members.

. lVhen the operations on an outer paper section coming from one of the hoppers, vshall vhave vbeen completed, an inner paper section or insert will arrive between the guide plates 79 and will dropdown between the disks and therefore into the openedout outer paper section. The stuffed fingers 87 and these fingers are maintained y in a lhorizontal position to sustain the paper section or lsections during the operations above described, by the engagement of a roller 137 (Fig. 2) on an arm 138 secured completed, the cam'139 On'the shaft 97 Will have moved t'o a position to release the arm 138 on shaft 88, when a spring 140 attached to said arm 138 will cause the shaft 88 to .turn and the fingers 87 carried by this shaft, to descend and thus remove the support for the stuffed paper' sections. Opposite the these shafts 97 and 97a carry clutch arms or jaws 141. The shafts `97 and 97"x are geared to rotate in opposite directions, .so that the armsor jaws 141v moving toward eael1other, will coperate to grasp the Astuffed paper sections and move the same downwardly between positively-driven feed` rollersl42, 143,. the latter being supported by a spring-pressed or yielding bracket 144. The stuffedpa-per .sections are fed by the rollers 142, 143 to one of a series of rotating delivery fingers 145, by means of which latter, the paper is placed upon a traveling. conveyer 146 which will carry the same from the machine.
