Fig.16 a; sectionon line 1.6-16 of F ig. 15.

The subject of this invention consists of mechanism. employed in connectionwith the illustrated'in the drawings; is intended for use inconnection with a newspaper.stufling machine for 'the delivery ofthe the assembling and stufiing mechan sm.

papers I to In such use theistack of papers is inclosed at two opposite sides, these conforming with the sides. of the machine, by upwardly extending bars 1 and 10,1 of which the ba'rsl from Which'thepapers are put in place and theshort bars 10 at the sideat Whiehthe attendant works. I

These arms are provided with feet 11 by atone side. are of considerable height,.whilet the bars 10-are of slight length,'the long bars 1 being placed attheside opposite'that which theyare bolted to the main jframe';

justed as is shown for thearms 10,in which the feet ll have slots 12v for thejclamping bolts 13.

The forward wall of receiving.

space is composed of a plate 2. which-is slightly inclined from a perpendicular. This plate, and the mechanisms associated therewith are separately shown' in Figs. 10J,and

11. This plate is providedwith two sets of e 'i slots, the "slots 20 for the receptionof the detent dogs 15 and the slots 21 for the pas-' sage of thefeed, chains 3. The upper ,slot 21 of each pair may mergewith a slot 20, as is here n shown. p p

The feed chains 3, each pass over gears 30,

, driven.

31, carried respectively on shafts 32, 33, of which shaft 32 is the driver and 33 the The chains pass from gears 30 through upper slots 21 to the face of the plate 2 which is next to the papers, thence down along the face of this plate to and through lower slots 21 to the gear 31. Idler and tightening secured to roc aft 36, engage the upwar runs of chains 3. Arm 37 on shaft 36 carries an adjusting bolt 38, which engages with a fixed member, as the outer side of plate 2, to thereby ad'ust the tightening gears 34.

The shaft 2 is driven through a'mechanism which is flexible, or compensating in the extent of its operation, whereby the movement of the chains 3 is ample for all occasions, but will be reduced in amount when encountering undue resistance. This has been secured by using a friction driving mechanism, as follows:

An arm 4, loosely mounted on shafit '32 is oscillated by means whichw-ill be later described. Secured to shaft 32 is a sleeve 40 having a flange 41. Sleeve 40 has a key way into which fits teeth carried by disks 42 and 43.to compel rotation together. 7 Spring 46 extending between disks 42 and 48 -force them apart. A disk 44 screwed on sleeve 46, acts as an adjusting nut. Friction 47 are interposed between a ratchet-wheel 49 and fla'n e 41 on one side and disk 42 on the other. he ratchet wheel 49 isvactuated a like'amount at each reciprocation of arm 4, but'the movement given shaft 32 will depend upon the slippage occurring between the rings 47 and their adjacent surfaces, If the resistance "to movement of chains 3 is great, there may be little 'or no movement *of the chains.

. The arm 4 is oscillated 'by a link '53 from shaft 5 which "is given an oscillating movement through crank arm 54, link '55 and crank pin '56carried by main shaft 57. Shaft 5 has an arm 50, having a slot 51 'for adjustment of pin 52, to which link 53 is connected.

The floor or bottomof theaper receiving d the forward side and the plate 2. The greater part of the front or lower part of the floor is-su omarmm bracket arms 6, projecting from a cross bar or plate of the frame. Be-

tween each pair-of bracket arm'sfi, is placed a guide "way inembr 61, which is shown in cross section in Fig. 16. This is of U-sha e in cross section, to fo'rm'agdidewaly far t f reception of the reciprocating bars 7 which carry the paper feeding dogs 8 51111137.

The side walls of guideway 61 have grooves 62 in which fit ribs or wings 01 the needle-carrying, paper-feeding bars 7. They are also recessed upon their upper edges to form cam .guideways86 ezitendmg beneath the flanges 63 and receiving cam gkrlaars 34 carried by arms 3 s rollers 7 5 carried by the back-feeding dogs 87. Bars 7 are pivoted at 79 to links 88 which are connected to arms 58 carried by oscillating shaft 5, a nd are thus reciprocated. This connection with arm 58 is by a slot in arm 58, so that they may be readily disconnected.

The feed dogs 8 are pivoted on pins 74 and lie in recesses 71 formed in the side of bar 7. They each have an arm 80 which is bored to receive a needle 81 which is adjustable in projection by screw 83 and clamped by screw 82. spring 84 acts to approximately compensate 401' the rotative efi'ect of on the dog.

The central 'en 85 of the dog projec'ts slightly a we the upper face of the plates 63, that is, above the surfaces which support the papers. In consequence this part of the dogs has a. considerable frictio n'a'l engagement with the papers when they are reciprocated beneath them. This results in rocking the dogs immediately any relative movement occurs between them and the papers. For a backward movement of the bars '7, this will throw the "needles down, out ofpaper engaging position, while for- Ward movment of *the bars relative to the pa rs, will cause the needle carrying ends to thrown up into engagement with the papers.

The paper retracting dogs 87 "occupy recesses 73 in the sides of the feed bars 7, being pivoted at 76 and havin' needles 77 mounted in their rear ends in li e manner to needles 81. These dogs carry cam rollers 75 which are adapted to engage the under surface of the projectingezdigc 65 of plates 63 to thereby depress the n e carrying ends of the dogs to hold their needles 77 out of engagement with the papers. This projecting edge65 iscut away at 64 and is lacking at the rear end of the feed bar. Springs 78 under dogs 87 will throw their. needles 77 up into engagement with the paper when unrestrained by the edges 65. This occurs only durin the latter part :of their backward movement.

Unde'rthe rear-0f the pile of papers is a supporting-bar 9 which has slots 90 therein registering with the feed bars '7, this being done merely to provide convenient means for insertion -a'nd removal of the feed bars. A considerable gffp is left between bar 9 and the "rear ends theplates 63. The effective width of this is adjusted by the use of a bar 91 whic-h is adjnstabl y mounted :onla-rms 92 which slide in holes in bar 9 and aresev justed' bolts. The purpose of thisis to 7 adjust the'jogging arms 95 carried by this rocker bar, for'action on papers of some: what difi'erent size, as well as to get the most favorable adjustment for a given size paper.

A link 96 is pivoted to the-jogging bar95 and has a forked or yoke shaped end "97 spanning and guided: by shaft35,or any. other suitable guiding support." .This link has a cam tappet,or'roller 99, which is actuatedby engagement with aycam surface100'upon a member as ,adisk 101, secured to and rocking with'shaft 5. The retu'rnmovement of the jogging arm is secured by a torsion s ring-102 mounted on the shaft 94 (see i ,,6 and 2). The active faces of jog .grngbars 95 are preferably roughened or t d, to. revent sliding of the edges of e papers t ereon. v

" uThe. front plate f the paper receiving bin is supported froma shaft or rod 104 carried in elevated position by posts 105. The upper edge ofplate 2 has yokes 106 adapted to embrace shaftlM. The plate-maybe vertioally adj l sted by bolts 24: which screw into the yokes106 and. are provided with lock.-

. nuts 107. I The lower edge of this. plate has i a bar2'6 which projects beyond its edges and has adjusting. bolts 25 engagin a frame member to adjust the lateral positlon thereof. -Fromthelower edge of plate2 fingers 22 extend into the paper storing bin, these "being raised a short distance above the surface 108 over which a the papers @are 'discharged. They are also a short distance above the top surface of the reciprocating,

needle-carrying feed bars 7, this distance .beings'in' a:measure.made, to conformto a "certain relationship with the thickness of the paper sections being operated upon.

' The paper when discharged from between thefingers 22 and the surface 108,=enters between the feed rolls, 109 and areprojected thereby through'the guiding bars 110, which deliver them to other mechanisms. The feed rolls 109. are held in yielding engagement by mounting one for lateral movement and "threaded'bolt 112. i

holding it toward the other by springs 111. Their approach together is limited by a In the operation of my machine the papers Pare placed intheir receiving bin or chamher with their folded edges against the front plate 2. Thisedge of the pile is supported,

;1n part at least, by thefingers 22. The-oscil lation ofdthenjogging arms 95 keeps the papers well upv against the plate 2.

' r The position of the feed bars 7 shown 'in Fig.15, istheir extreme advanced or projected' position, and the paper which has i been removed from. the pile is supposed to have been takeniaway by the feed irolls 109. 9 The back-feed dogs 87 are heldfin inopen ativeposition by their rollers being under the edges of] plates 63;

In.moving backwardythe 'frictional en I gagement of the central boss, with the underv surtaceof the papers, rocks their needle carryingends down to wheretheir.

needles will not scratch the apers, flSlS seen in Fig. 4:. When the rol er 7 5 of the back'feeding gs: is freed from th m.

jecting edge 65 of plate '63 spring 78 throws engage the lowermost paper" to move 7 it backward.

- This action is timed to occur only a short time before the termination of the backward upits needle carrying end and-its needles 77' movement'of thefeedbar. In consequence of this and of the gap in the-floor just forward of thesbar 91, the lowermost paper is buckled downward into this gapyas is shown in Fig. 4. The'for'w'ard edgeofthepaper is l o pulled: ofl the fingers 22. When the: feed bars are advanced,the frictional .engagement with vdogs Si-l k their needle carrying ends to causeYtlieir needles 81v to engage the paper. Theprojection of these needles is such as to: pene- I tratewell into, if not mostly through, the lowermost paper. This paper' will thus. be

advanced and projectedbene ath fingers 22 into the feed rolls 109.
