T all 'whom it may concern: n

Be. it known that I, CARL HEiNzi-JN, a citi zen of the United States, and a resident o f Chicago, county of Cook. and State of Illinois, have invented certain new and use ful Improvements in Bag Filling and Tying Machines, of which the following is declared 7 to be a full, clear, and exact description.

The improvement relates to bagging inachines and more particularly to the mechanisin for automatically tying up the mouths of the bags as' the latter are filled.

The invention seeks to provide reliable and. cti'ective mechanism whereby the bags may be rapidly filled and tied andthe invention consists in the features of construction, combinations and arrangements of parts hereinafter s et forth, illustrated in the 'jaccompanying drawings and lmore -particuvlarly pointed ont in the appended claims.

In the drawings, Figure l is a` plan view of the machine. Fig. l is a side elevation thereof.- Fig. 3 isa detail view of one of the grips or catchesfor holding the month of tlhe bag. F and 5 are sectional views taken on the lines 1- 11 and respectively offFig. 1. Fig. 6 is a 'front view of the slotted cord-guide. Fig. 7- is an enlarged det-ail view of part of the operating mechanism shown in Fig. 5. Fig. 8 is a horizontal .section on line S-#Q of Fig'. 4.I Fig. 9 is a similar view with thc neck-forming jaws shown in closed position and with parts of- .salte of clearness.

the operating mechanism omitted for the Fig. 10 is an enlargedAIV detail section on line lO-l() of Fig. 1 1.' Fig. 11 is an enlarged detail plan view of the cord mechanism in the position assumed after it has passed the cord around the neck of the bag. Fig. llais a detail section on line u-u of Fig. l1. Fig. 12 is a side elevation thereof with certain parts shown in section. Fig. 13 is a detail section on line 12-5--13 of Fig. 11. Fig. 14 is a detail section on line 171-14 of Fig. 12. Fig. 15 is a sectional view of the wire twistingdcvicc and its operating mechanism. Fig. 1G.is an elevation thereof with the .slotted guide plate. omitted. Fig. 17 is an elevationof the inner face `of the slotted ordguide. Figs. 18, -19 and "l0 are views illnstratiiigthe operation of the wire twisting device.

The frame of the inacliine. comprises the side pieces lwhich are preferably formed of cast metal and provided with legs 2. The latter are shown broken away but are of sufficient length to hold the machine at the desired height: The side pieces 1 are connected at their u per ends-by the cross angle' bars 3 and by tie cast member 4, which is provided with a central depending 'portion or mid-rib shown in Figs, 2, 4; an 5. The

-inain drive shaft 6 isjournaled in the sides of the f'ame and carries a drivepnlley 7 'on its outer end.' A supplementall 'drive shaft 8 is jouriialed between the sides of the inacliine and is connected by gears 9 to the mani drive shaft 4(i.

A pair of guide rails 10 are mounted upon the top cross pieces 3. These guide rails are preferably formed of angle bars, as shown, having upwardly extending flanges and they project beyond the front end of the machine. A ring-.like carrier frame 11 is arranged to reciprocate on the forward ends of the guide rails 10. and, for this purpose, is provided with grooved rollers 12 that. engage the upwardly extending flanges of the guide rails. The. reciprocating carrier supportsa hopper 13 tlironghvwliich the grain or other 'inateria] is directed into the bag. is also provided with a series of catches for engaging the 'month of the bag andholding it open beneath tlielower end of the h opper.

the upper end of the central cylindrical portion of the carrier'frame 1l (see Figs. land 5) and rests. as shown, .on the fiange 11 above the 'radially projecting ribs or lugs 15.`

The carnis held against lvertical movement` b v a ring or washer 1S) fitted about and secured to the inner end ofthe central cylindrical portion ot the .carrier frame.

The carrier frame lsoscillated upon the The carrier V that is loosely )ouriialed at its lower end' guide rails '10 by a shifter-rod or lever 20 upon the main drive shaft 6 and extends upwardlvtherefrom, and which carries a pin i' or roller 21 engaging the slot of a cam 22 on the counter-shaft 8 (see Figs. 5 and 8). A

` pair of links 23 is pivoted to the upper end of the lever and to a radial rib or abutment' 24 on the carrier. I

The catches 25 for holding the mouth of lthe bag are preferably hook-shaped (see Figs. 2 and 3) and pivoted-between pairs of plates 26 that are secured te the lower ends of the arms 14. .'Each hook-like 'catch pref-A erably extends upwardlyand inwardly from .its pivot, and its free end is held byV a leafspring 27 intoengagement with an abutment 28 secured between the plates 26. The lower ends of lates 26 are cut away so thatfthe edge of 'the mouth of the bag may be quickly and easily slipped into place" between the hooks 25 and the abutments 28 when the catches are in their outward position. Each I catch is provided with an upwardly extend- .ing

' the main frame by a pivot bolt 33 and at. its .other end to aslotted lug 34 on the ring Y frame by a pivot bolt 35.

. of the arms within thc inclined l'iortionsof The connecting link is preferably made adjustable for vary- 'ing the throw of the cani-,ring and such adjustment is, preferably effected by forming the link of separate sections having the right 'and left hand screw threads and connected by a turn-buckle 36. It will be noted as shown in Fig. l, that a part of each of the cam slots 17 of the ring 18, extends in circumferential direction while a part of cach slot is inclined. As the carrier frame is moved inwardly toward the maitl frame of the machine, the cam-riiig, as it moves inwardly with the carrier', will be so turned as to bring the rollers on the .J upper ends of the arms 14 within the circuinfei'entially extending portions of Athe cam slots. In this position, the catches on the lower ends of the arms will be held tosizes.

As soon as-the bag is filled, the carrier is moved toward the main frame and the catches on theflower ends of the arms 14 are moved inwardly to close the mouth of the most position of the carrier frame and catches, the upper portion of the bag is Fand bag-tying mechanism. As shown in Fig. 5, the slot of cam 22 is so shaped that the carrier frame will. be held stationary in its outermost vposition for a considerable part of the revolution 'of' the counter-shaft 8 duringwhich time the bag is placed in position upon the catches and filled. The bag will then be quickly drawn in and held in its innermost position during the operation of the neck-forming and.' bag-tying mechanisms. The carrier frames will then-be moved outwardly to receive a new bag. A spring 37 extends between the upper end of the shifterframe so'iis to take up lost motion of the pin steadyingt-lie motion of the carrier and securely holding it in its outer and inne'r positions during the bag-filling andbag-tying operations respectively. f l

At the end of the bag-tying operation, the catches 25, which hold the bag, are preferably automatically 'released' by a. suitable mechanism. In the forni showinthis mechanism comprises a plunger 38'of-inverted frustum-cone shape that is pivoted upon the lower end .of a'link 39. The latter is pivoted to the end of an arm 40 upon a rock-shaft 41 .that extends across the front ot the machine at its upper end and is joiii'nalcd at its ends in brackets 42. .X rock-arm 43, on the en d nected by a link 4l to a rocking lever 45 pivoted on the side of the frame. A spring 4G extending between the end of the arm or holds a pin or roller 48 on the arm into engagement with a cam t9 on the end of the counter-shaft S. 'lhe holt 50 that connects tends through a slot 5l so that the extentof the throw of thetripping plunger may be brought into the path of the neck-forming- 'rod 20 and the rcarci'oss bar Bof the main or roller 21 within the slot of cam 22, thus of the rock-shaft 41 (sec Fig. 2), is con-' lever 45 and an upright bolt. 47 on the frame? the link H- with the arni 43. preferably ex.

getheizas shown in Fig. 4. lVlien the carrier frame moves outwardly the Cain-ring will be so turned as to bring the upper ends adjusted as is necessary. Link 39- abuts that it is normally held centrally over the inner position of the bag-holding catches. As theplunger 38 is shifted downwardly, it engages the tail portions 31 of the trip dogs the cam sie' and the catches will be moved outwardly oi" apart, as indicated in Figs. 1 and 2. In this position, the bag may be placed on the catches and it is then filled by admitting grain or other material through theI hopper 13.

The extent to which the catches are moved outwardly may be varied by adjusting the length of the controlling link 32 so that the against the tension of the springs 27 so as to release the bag. The inner ends of the tail portions 31 of the tripdogs 30 are inclined downwardly and iiiwardly as shown, in corplunger. 38, so that the plunger, which is 30 and shifts the catches 25 outwardly.

machine may be used with bags of different bag as indicated in Fig.- 6, and in this inneragainst a shoulder 52 on the rock-arm 40 so respondence with the conical shape of the 30 shaft 8.

freely suspended on the link 39, will accurately center itself as it is shifted downwardly-and will trip all of the catchesto release the bag.

,5 In the innermost position of the carrier, the upper portion ot' the bag, as indicated in Fig-4, is held against or closely adjacent a guide bar that is preferably curved and preferably forms a horizontal flange on lo the lower edge of a curved frame member 54 (see Figs. 2, 4, and 8). The neck-forming devices for gathering the folds at the mouth of the bag are preferably in the form of a pair of jaws 55 that are mounted on the outer ends'of arms-5G. These arms both extend through an opemng 57 1n the midsection or rib 5 of the main frame, and are jnournaled at this point on an upright pivot olt 5S. A 'pair of links 59 are pivotally connected "at their forward ends to the ends fof the arms 56 and areconnected at their rear ends bya common pivot bolt 60 to a U- 'shped piecefil, as most clearly show'n in Fi f4., The latter is connected by a pair of fend of a shifter-rod 63. T 11e-latter is loosely '-journaled at its lower end on the shaft (3 and carries a pin -or roller 64 which engages the'slot ofacam G5 on thedrive The outer ends of the arms 56 extend beneath the guide-bar 53, and'l are provided -with clips 66 that extend orer the guide-bar so that. the weight of the neck-closing jaws is lsup orted at this point. 4The mechanism v"-descri d is arranged to expand and contract I the operating arms 56 and neck-'forming jawjsf 55. "The lat-ter 'are provided with fingers 67, the ends ofwliich are just below I 4g' the outer edge of the "guide-bar 53. The

jaws. are also provided with forwardly and lnwardly extended .portions (38 which en- 4gage the u per portion of the bag as the jaws are moved inwardly. In this latter Aposition the neck-,formingr jaws overlap, as

`shown in Fig. il. leavingr only a round opening .between the fingers ($7 and projecting iortions (1S through which the 'neck of the ag extends. V j

The cam ('lis so shaped (see Fig. 4) that` the jaws areheld in `stationary open position as the bag is being filled. 'hen the upper portion of the hag is-moved inwardly the jaws are Quickly closed and are shaped, as described, to gather the folds at the upper portion of' the bag into a neck so that the mouth of the bag is hehlsecurely closed. The-jaws are held in this position during the bag-tying operation. no 3.7Be11eath the center of the guide-bar 53 and in rear of the position in which tht` neclf of the bag is held hy the jaws 55, is ar- I' ,ranged a block G9 that is preferably formed "of separate upper and lower` sections bolted 8a together, the upper sectionof the block be-v `ing secured to or cast in -piece with the guide-bar To the front. and atene end of. this block is secured a guide plate 70 (see Fig. (t) that is provided with ahorizontal guide 'slot 7l having a flared open end. 'lhe sections of the guide block 69 are shaped to form a corresponding guide.

slsit, as indicated in Fig. 5.

In rear of the blockl 69 is arranged .the duplex cord clamp and cuttcm that 1s car-` ried upon a short, vertical spindle or shaft 72 journaled in lugs 73 projecting ro'm the rear face of the curved frame member 54 (see Figs. 5, 8, 11, 12 and 14).A A spur inion 74, fixed to, the spindle between the ugs 73, meshes with a spur gear 75 loosely journaled nponthe upper end of a short shaft 76. The latter is journaled in a suit-- able bearing in-the forward end of the midsection or rib 5 ofthe main frame. An arml .77 (see Figs. 4 and 12) fixedv to` the lower end, of the vertical.'shaft v76 has a bolt and slot connection with the forward end of a shifter-rod 78 (see dotted lines in; Fig. 9) that-'is guided in suitable bearing lugs` 79. on the lower edge of the-mid-rib'.. A spring 80 coiled aroundthe rod extendsbetweenthe rear lug79'and acollar 81 on the i end of the rod, andlnormally holds it in retracted position.-

A finger 82 on the counter-shaft 8., is ,ar-

ranged to cngage.a"slot 83 in the shifterrod to project` it forwardly, once A for every operation of thelinachine, a sutlicient extent to rotate the shaft 7G through a Lquarter turn. As soon as the finger 82'passesi'on out of the slot- 83, spring 80 'returns the shifter-rod to its normal position. 'Anarm 8l on the npper end of the shaft 76 (see F igs? 8 and .12)

carries a 'spring-held pawl 85 which is arranged to engage a ratchet wheel 861that is secured to the gear 75. Ratchetwheel 8G has four teeth so that at the proper time in eachoperation of the machine, shaft 7G is given a quarter turn .and spindle 72 is given a halfturn since the gear 75 has twice as many teeth as the pinion 74..

The duplex oord clamp and cutter is clearly shown in Figs. 1l. lil and 14 and comprise upper and

lower members

87 and 88. vThe lower member 87 is fixed centrally upon the lower end of the rotatable spindle 72. as clearly shown in Figs. 11 and 14. The upper member 88 of the clamp is of'inverted U-shape as indicatedin Fig. llpaud sets over the lower member 87 'and -is cen-- trally plvoted theretoby the pivot screws 89,

and the members are so shaped that. .when in engagement at one end-their opposite ends will be separated as shownin Fig. 14.

A statit-nary cam 88 is fixed upon the under face of the lower lug 73 and extends about the rotating spindle 72. This earn' engages the upper face of the oscillatingclamp-mem- -ber 88 and holds it in the position shown 1n fai' one end of the lower clamp member 87,

while the opposite ends of these clamp members are open, as shown. The opposite' ends' ofthe. two clamp members thus form in effect, two pairs of jaws, one of whichus normally closed 4and the other of which is normally open. Vhen the spindle 7 2 is given a half revolution as described, the upper and

lower members

87 and 88 of the duplex clamp are also rotated a half revolution and the fixed or stationary cam 888L will shift the upper oscillating clamp member 88 to separate `the engaged ends of the clamp `members-and bring -together the opposite ends thereof. That is to say, at each halt revolution of the spindle 72, which occurs at each operation of the machine, the closed pair-of jaws of theclamp members is opened and the opened pair of jaws is closed. The

upper oscillatingclamp member 88 is provided at each side and near its opposite ends withdownwardly extending cutting knives 90 which cooperate with upwardly extending cutting knives 91 on a plate 92 that is' fined to the rotating spindle'72'ibe1ow the lower clamp member 87.' The

knives

90 and 91 at the closed ends of the clamp mem'- bers are in engagement, as shown m Flg. 12,

.while'the knives at the opposite or opened ends ofthe clamp members are separated, as shown in Fig. 14.

A shifter-arm 93 (see Figs. 8, 9 andll) is arranged below the guide 53 and is oon-4 nected thereto at a point toine side of the center, by a pivot bolt 94, An operating arm 95 is connected by. a pivot pin 96 to a lug on the mid-rib of the main frame and is connected to the shifter-arm by a link 97. A bolt 98, fixed to one of the jaw-operating arms 56, extends through a slot 99 in the arm 95 so that the shiftenarm 93 is actuated, as the neck-forming jaws shift to closed position1 to carry the cord around the neck of the bag, as shown in Figs. 9 and 11. The cord shifter arm 93,the end of the operating arm 95 andthe connecting link` 97 are bent,as shown, so that 4the cord may be properly carried around the neck ofthe bag.

The cord shifter arm is provided Aon its end with a pivoted dog 100 (see Fig. 11) that is held by a spring 101 against the shoulder 102 on the arm. The free en d of the cord is held between the closed pair of jaws of the duplex cord clamp and extends thence outwardly through the slotted cord Guide and then through an eyelet in the .end

(tif the dog 100. and thence through a series of guides '103 on the shifter-arm. The open position of the neck-forming jaws and cordl shifter is shown in Fig. 8. As the jaws are brought together into the position shown in Fig. 9, the shifter-arm operates to carry the cord around the neck of the bag and again cord clamp and cutter (see Figs. 11, 12 and 14). The ends of the cord about the neck' ofthe bag are' then-secured together, as hereinafter described, and the duplex cord' ,clamp is then given a half revolution by its" y operating mechanism, so that its openpan' o Jaws 1s closed and the cutting

knives

90 and 91 thereon operate to sever the length of cord secured aboutthe neck of the bag, and' the new free end of the, cord is gripped. At the same time, the closed pair of 'aws are opened to release the length of cor around the neck of the bag and are moved around into position to receive the cord at the next operation. The .return movement" of the neck-forming jaws and cordV shifter carries the cord back out through 4the slotted cord guide and into positia'nshown in Fig. 8 in readins to tie u the next hangt.A

A suitable device is preferably employed for tightening the cord after it vhas been passed around the neck of. thebag by the shifter-arm. This tightening device .com prises a pair of jaws 105 (see Figs.'5r,' 11, 12 and 13) which are mounted'upon aiblock 106 arranged to slidein a -slot or 'guide-way 107 in the lower portion .of the-.midjrib 5.

The side of this slot is open and is closed by a plate 108. An operating sprin "109 1s arranged within'the guide-way 10% and is connected at its end sto theblock 106 and to the frame of the' machine. Block 106 is provided with a bar 110 arrangedy to 'slide behind the plate 108, and having a `laterally projecting pin-111 at its rearfend `which is arranged' to be engaged by a finger 112 .on

the,l counter-shaft- 8 (see Fig. 4). The'enl gagement of the finger or rod 112 with the pin 111. shifts the cord-tightening device forwardly and the'latter is heldin suchis provided with acontracted portiony at its outer end (see Fig. .11l-,so'that'3the projecting or outer ends of the saidjaws are held -open when lthe cord-tightening device 4is in its for-ward position in engagement with the latch 113.

. The outermost position of the -ijaws of the cord-tightening device is indicated in dotted lines in Figs. 9 and 11. In this position the cord will extentl thfough the open jaws/when it is passedaroundlthe neck i 41,0eaf/ee y 5- of the bag by the shifter-arm. A lug 117 on' the shifter-ar|n 93 at the end of its movement., strikes against a projection 118 on the spring latch 113,. (sce Fig. 11) and releases it. so'that the cord-tightening device is drawn rearwa'rdly by its operating spring. As the outer ends ot' the jaws are drawn rearwardl')Y into the contracted portion ofthe slot 115, the jaws are closed, grip the cord and draw it tightly around the neck o'f the bag` The spring-held dog 10() on the. end of the 'shifter-:nan vields to permit this rearward movement ot the cord-tightening jaws. After the shifter-arm has returned to its initial position the cord-tightening device is again shifted to its forward position into engagement with the latch 113, and as the inner ends ofthe jaws pass into the contracted portion'of the slot 11G, the outer projecting ends are again opened to receive the cord: at the next operation of the machinelf' y, Y f

The ends of the length of cord around be neck of the bag are secured together by. winding a length of wire. around; them. I'hisiwire winding lor twisting device is .arranged withinthe-sectional block 69 in.

rear of the slotted guide plate -70 (see Fig. 12 and Figs. 15 to' 20Jinclusive), and comprises inner and outerv rotatable members 119 and 120.- The outer member 120 is provided with a socket within which' the inner member 119 fits and both members are provided with radial slots that extend to the centers of the rotatable members and that are normally held in line with the slots of` the block 69 and guide plate 70. -The inner n ember 119 of the wire twist-ing deviceis positively driven andfor this purpose is provided on its inner end with gear teeth 121 that mesh with the teeth of an idlcr122 ont a. short shaft 12.3 mounted between the sections of the block (39. 'Ihe outer end of a horizontal shaft 124 extends between the sections of the block 69 and is provided with a gear 125' meshing -with the teeth of the nier-122. rhis shaft is joumfaed in Sua;

.able bearings 126 on the lower end of the mid-rib o1' the main frame (see Figs. 4,'5J

and 9) and atits rear# end is provided with. a beveled gear 127 meshing with a beveled gear 128 on a cross shaft 129. The latter sh'aft is mounted in suitable bearings 130 (see l "ig. 8)- on the mid-rib of the frame and on one of the sides of the-frame; and carries1 a pinion 13] that meshes with the teeth ofthe gear 132 on a cross shaft 133 journaled in suitable bearings 134 in the sides of the main frame. '.lhe shaft 133 (sec Figsfyand 8) is provided with a small gear 135 'that is arranged to be intel-'mittently engaged by thtl teeth of a mutilated gear lt-'e' on the driving cr counter-shaft 8, so that at. 'proper intervals shaft 124 iS rogearing, describe and ,is: provi tatcd to operate the wire twisting device.

VThis drive gearing isklsuch that the wire twister is given exactly two revolutions at each operation of the machine.

In order that the slots of the wire twister, when in idle posit-ion, shall be accurately held in linewith the slots of the. cord guide plate 70 and in proper position to receivethe ends of the cord, its drive mechanism is provided with a Geneva stop movement. For this purpose the multilated gear is provided with a cylindrical locking surface`137, (see Fig. 7) which cooperates with a locking wheel 138 on tlie shaft 133, and 'this locking surface is lprovided ,with a cutaway portion 139 opposite the teeth of the 80 mutilated gear so as to permit the passage of the raised portions of the lookin wheel 138. By the mechanism described, -t e wire twister will at proper time, be given two revolutions. At all other times it will be locked against movement and held withits slots in line'with the slots of thecord guide. The inner rotatable member 119 of the wire twister is thus ositively driven by the endiwith. an eccentricfin erj'lft (seeiFfgS.- 15 `and 16)y vthat extends t` roug'hjafslot"'141 in the end of-the outer"member`12:0,"5" the outermemberis 'drivveiiib'y tlieiefxi'gagment rofthis finger with th-end' of theslo't) g5 but the slot vis somewhat.' larger.tha'.n' the finger so that thereis "a lost motionl connection-between .the members ofthe `wire twisting device. The fingers 140 and` the Aend of the "slot l41'also serves as a gri for ,the 100 lengt-h of wire to be twisted aroun the ends of the cord. The `outer member is provided with ,a groove 142, the bottom of whichis raised at one portion to form an abutment 143. The surface of this abutment is '105- even with the cylindrical surface of the, cylindricalmember 12()A and "is provided with a depression 144 (see Figs. 19 and 20)- t-hat israrranged-to' be engaged by the end of a spring-held plunger 145, extending {xp-" wardly throng the `lower section Aof the block 69. By this lm eans the outer loose member of the wire twistin device is. held in its idle position with its s o t in proper posit-ion' to receive tlie ends of the cord. In 115 this position too, the rip fingers 140 in the forward edge of the s ot 141, are held apart to receive the end of the fastening wire.
