Original No. 1,478,560, dated December 25, 1923,-Seria1 No. 324,275, filed September 118, 1918. Application for reissue filed May Mry 1925. Serial No. 30,376.

' To all whom, tkm/,zy concern.:

Be it known that I, CHARLESr E, EVANS,

a citizen of the United States, and a resident of the city of Seattle,` county of King,

5 State of lVashington, have invented certain new and useful Improvements in Bundle Binding and rIying Machines, of which the following is a specification.

My invention relates to bundle tying machines of that class in which a wire is drawn and secured taut about a bundle which may consist of a number of articles of like'kind assembled together, a box o r any kind of a package or bundle of limited dimensions .15 about which itis desired to secure a binding wire.

The object of the invention is to improve upon machines of this'character as formerly produced for/doing the same or analogous work, and more particularly to 'provide a machine comprising improved details of construction such as adjustable tables for.

supporting the bundle,'automatically operable toward 'and from clamping' arms, means forCa holding the primary end ot a wire strandwhile itis Wrapped aboutthe bundle,` for twisting the endabout the main strand, for

i'ngfthe twisted ends beneath the-taut band.

Referring morexin detail to the draw# in s:

ii designates a base whereon the operating parts of the machine are mounted, the same being somewhat rectangular in shape and is provided with an edge flange whereby the horizontal portion is somewhat raised.

Mounted atthe two rear corners of the base are spaced sandards 2 and 2', each provided with a base flange 3 secured by bolts 4. These standards carry the rotative annular rings by which binding wires Vare applied and the mechanism mounted thereon at the point slightly beyond the center of the base.

Mounted on the base 1, on a plane midway between the standards 2 2', and at each side vof the point, are two standards 5, see Figures 8 and 9, each having a flanged base portion 6 for receiving anchor bolts 7,

and having vertical channels or guideways '8 wherein posts 9 are movably mounted.

Mounted on each of the posts 9 in horizontal alinement with each other, are bundle supporting tables. 10 which when moved upward cooperate with the horizontal portions 11 of yarms 12 to compress a bundle that may be K supported thereon.

The arms 11 and 12 constitute ol'set extensions ofthe standards 5. l

The arrangement of the bundle supporting tables is such -that a bundle4 mounted inY position thereon for., tying, will 'lie' appro-xi'- .mately Iin the .axis "of the annular members supported by the standards2--2A and iper,-

' pendieularly to'theplane thereof..Y L

l`he annularmembers, 'before mentioned,

supported by the standards 2 2', comprise a central or stationary ring 15 which is hol'- low and rectangular in cross section and is rigidly secured to thev'standards by bolts 16, Figure 5, whit l1 extend through the ring and standards, and are drawn tight by nuts 16' to hold the ring rigidly in a vertical plane.

Mounted l'evolubly on the exterior and interior of the ring 15 respectively, are rings -18 and 20,'the former having a toothed fiange 19, forming a spur gear and the latter having an annular toothed ring 21 iixed to its forward edge forming a bevel gear, and a spul' gear 22 formed upon its rear edge.

,Each of the ,rings 18 and 20`is revolubly supported, as by rollers 23, (Figure 24) mounted within the ring 15 and haring peripheral flanges or ribs extending therefrom and entering annular grooves 25 formed in the face ot the rings. It is preferable to provide three rollers for the support of caen ring and to space the rollers at degrees intervals starting from the top of the ring in such a manner that the central upper roller. and the two bottom side rollers support and retain the inner ring in functional position, while the bottom and two upper side rollers simultaneously support and retain the outer ring.

4bundle against the horizontalwarms 11' takes place immediately after starting of the machine by a vertical movement of the tables and the bundle is held in this position until wrappingand tying has been completed. The means for doing thisiwill be later dey scribed.

The mechanism employed for driving the revoluble members comprises, for the outer ring, a gear wheel 26 which meshes with the toothed peripheral flange 19: the gear 26 is keyed on the shaft 27, which shaft is supported in bearings 28-29 carried by brackets 30-31 that are fixed to the standard 2.

The inner ring is driven in the same direction as the outer ring through a train of gears comprising a gear 33 which meshes with the geared periphery 22 of the ring,

an idler gear 344a11d a driving gear 35, the 1 latter being keyed to the outer end of a sleeve 36', which is revoluble Within the bearing 28 and upon the shaft 27.

Each ring is individually driven from a belt driven pulle)r rwheel 40 Vthrough the in- 1 =keyed on t-he shaft'r27 while the clutch 42 is likewise slidably keyedV to the sleeve 36.

i The pulley'wheel 40 is freely revoluble on its mounting between the clutches when the machine is 1n neutral position. y

Assuming that the clutches are in neutra'l position, to start the machine, I have provided a foot lever 44 Figures -3 and 6) which is pivotally supported from adjacent its rear end by a bolt 45 extended into the standard 2 and is yieldingly retained in a raised posit-ion by a spring 46 fixed at its opposite ends to thc'base l and endet the eve-1'.

Connected to the lever 44 by a pin and vslot connection, as shown at 47, ale links 48 which are pivotally fixed at their upper ends to an ear 49 extendingr laterally from a cylindrical sleeve 50 that is revolubly mounted on al stub shaft 5l projecting from the standard 2. At its outer end the sleeve is closed and has a pin 52 extending eccentrically therefrom, which pin has connection with a horizontally disposed shifting bar 54, the latter being supported by and having pivotal connection with, the lower ends of a series of centrally pivoted, clutch controlling and shifting levers 55, 56 and 57. The levers 56 and 57 are provided with yokes at their upper ends which partially enclose the hubs of their respective clutches and havethe usual connection therewith, so that longitudinal shifting. of the bar 54 simultaneously moves the clutches to engage one with and disengage the other from the driv-V ing pulley, or to' place and retain both clutches in a neutral or disengaged position, as the case may be.

The lever is fixed to a rocker shaft 55 wherefrom two arms 58 and 59 are eXtended. These arms carry rollers 58 at their ends, which rollers are engaged at certain times during the operation of the machine by cams ot such shape and fixed at such position'V on the revoluble members that they will rock the lev-er 55 to shift the clutches so as to thereby drive first the outer ring and then the inner, and then to move Vboth clutches to a neutral position to stop the machine at the end of a tying operation.

lith the parts constructed as so far described, it will be seen that pressure applied to 'the forward end ot the foot lever will cause the links 48 to draw downwardly on the ear 4!) to partiallyr-etate the sleeve 50, which `will, by its eccentric pin connection with the bar 54, shift the. latter to thereby actuaterthe levers 56 and 57 to nio-vel the clutch 4l into driving engagement wit-h the pulley 40 and the clutch 42 away from this pulley. Power is thereby transmitted through the shaft 27 to the gear Q6 and the latter starts the outer ring 18 revolving about the stationary ring and bundle.

Fixed to the forward face of the flange 19, which terms a part of the ring 18, is a cam plate 64 having a somewhat abruptly inclined cam track member 65 vfixed thereto which, shortly after starting of the machine,

- engages with a roller 66 carried byv a piv- Y-shaped lever that is pivotally supported by a shaft- 70 between spacedy bearing 7l formed on the base 1. l`The twolegs 72 and 72 forming the inner part of the lever, extend to a point adjacent the lower ends ot the` two posts 9, whereon the tables-,10 are supported, and are connected with these f legs, as by means of a sha-ft '78,.which extends'through the ends o'l' both the lever legs and the posts. I

lith the connection described, .when the outer ring startsite revolve, the cam surface engages the roller 66 moving this end of the arm 66 downwardly and outwardly so that it acts as a .toggle link in connection with the rod 68, to rock the Y-lever and move upward the bundle which will bev supported on the tables 10, into clamping engagement with vthe parts cooperating with the tables, as the retaining fingers 11.

As the arm 66 is ro-cked on. its pivot to clamp the bundle, it moves to a point slightly beyond the dead center, that is theline connecting the 'center ofthe shaft 27 and the point of connection otth/e rod 68 withthe lever 69, as shown in Figure 8, so that. the bundle will be retained in this clamped position until it is positively released.

This releasing is effected by engagement of thel forward end of the cam plate 64 with a roller 74 at the outer end of an arm 74 that is formed integral with the shorter arm 66, the two arms being in such relation that thearm 74 moves inwardly into a position that it will be engaged by the cam 64 as the outer ring nears a complete turn, while the army 65 is being'moved outwardly on the initial movement of the ring. It is apparent that by forcing the arm 74 outwardly, the armv 66 moves inwardly past its dead center position, which allow-s the bundle supporting tables to move downwardly to release the clamping pressure upon the bundle.

To provide an adjustment which wil'l accommodate bundles of diii'erent thicknesses. I provide means for adjusting the length ot the connection between Jthe arm 66 and the lever 69. As a desirable means `tor doing this, I mount a sleeve 75 about the lower end of the rod 68, which sleeve has a threaded connection at its upper end with a threaded portion 76 of the said rod. keyed to the sleeve so that the latter may be A wheel 77 is after adjustment.

revolved and therebyadjusted to different "positions along the rod., The lower part of the sleeve carries a collar 78 whereto pivotal connection with the lever 69 .is made, and at its upper end is split and has a locking wheel 79 with a tapered bore. threaded tliereover, to clamp the split ends of the sleeveagainst the. rod and prevent rotation of the sleeve 'The collar 78 bears against a. coil s rinor '80 which surrounds the sleeve and rod, so

After a bundle' has been placed in position f and the machine has been set in motion by a. downward movement of the foot,V lever, the first operation, as has been described, is the clamping of the bundle bythe movement of the tables 10, but as the outer ring continues to revolve a wire is passed around the bundle, as will now Vbe described.

Mounted on the ring 18 is a reel 85 wherein a 'supply of wire 86 is wound, the Wrapping end of the wire being passed from the reel through a tensioning device, shown in Figures 25 and 26, which comprises a series of offset sheave wheels ,88 tixedto a. plate 87 that is secured to the face of the cam plate 64. After passing'over a guide wheel 88 the wire is extended to and held by a twister head 1carried upon sleevep90 that is xed to the front face of the stationary rin 15. lVith the wire secured in this way it will be seen that as the outer ring revolves, the wire will be paid out from the reel and wrapped about the bundle. The reel is vretained in l -position by means of-yieldable stops 910 (Figure 26) which extend outwardly from blocks 920, Vthat are secured to the ring 18,

so that the projecting ends of the pins enage'gthe outer side face of the sufiicienty to retain the ring 85 in place. A necessary slippage between the reel and the Vring is provided for by mounting the latter on a.

number of yieldable sprmglike' spacing strips 930, as shown in Figure .24, which en gage adjacent faces of the twoinembers.

The wire twisting head'and cutting member which retains one end of the wire during wrapping, is shown in relation to the other parts' in Figures 1, 1,1 and 12 and separately in det-ail in Figures 14, 15 and 16. As this is substantiallyT like a device'shown in another application to be filed by me, it will hereinbe referred to only generally. This vtwister h ead comprises mainly a short rotatable tubular section 90 provided at its inner and outer endswith bevel gears 91 and 92, respectively, and 'is revolubly mounted flanges 91 and 92*l which pass outside of and engage the, ing the cyli der 90 and its parts in place. The "flanges 91*l and 92 are continuous -V throughout .the circle exceptl for the wire reciving slot 100 hereafter described. l

The tube 90 is preferably' mounted in sucha manner that the line of itsf axial centerk liesV in a plane which includesthe axial center of the ring 15. This is dictated chiefly by the lsimple bevel gear construction of the operating' means which maybe used when so located.

head 90 is la plate 98 which has a wire re.- ceiving slot 99 therein registerin'gwith a lil-:e slot 100 extending longitudinally of the head. A toothed wire cutting Wheel or disc 101 is journaled at 102.in the plate 98 at one` nges 93, thereby securely hold-y Fixed to theinner end of-.the rotative.

the wheel is Iturned coact withthe plate 98 to -form wire cutting shears. The-axis of the Wheel 101 is so located-that the bottom of the groove therein asitis turned will be brought into registry with the axis of the head' 90.

The projecting portipns between the recesses function as teeth by engagement therewith ofa tooth 104 carried by a canLplate 105 which is fixed to the inner curved ace of the inner revoluble ring 20, so that on each revolution of the ring the cutter is revolved one tooth space, thus cutting the wire in the slot 99. The means for cutting the `wire and for holding the wire end may be such as shown in my application hereinbefore referred to or any other suitable mechanism. rThis'should be such as will se" curely hold it against the strain of putting the wire aboutA the next bundle.

At the start of an operation the in the positionshown in'Figure 1. he wire has its end secured between the cutoff wheel 101 and the plate 98, fixed to the inner end of the' rotatable head. It extends thence across the bundle, through the tensioning Vmechanism and to the reel.

ring revolves, the wireis wrapped about the bundle, passing between the edges :of the spaced tables 10. The movement of the outer ring is temporarily stopped when the Wire hasiene'losed Athe bundle, this being at a ltime when the outerring has made approximate- 'ly three-fourths of a revolution.v

Mounted on the side face of the stationary ring vatopposite sides of the twister head,

are wire clamping arms-108 and 109, 4whereby a ,wire wrapped about the bundle is the bundle at opposite side head f function properly. The upper clampingarin 10S is actuated soon after the wirel "has-been drawn acrossthe top ofthe bundle while the lower armf109V moves tor clamping position asA 'soon as the wire is `in position for twisting; both clamps being actuated to clamping vposition 'by engagement of the forward/ end of a sector 110 that isfixed tothe outer ring, with certain' parts working in conjunction with the members. Operation clampsis illustrated in Figs. 11 and 12 and is as follows:

' The clamp arms 108 and 109 are pivotally mounted on pins 111 and each vlh AAcurved, and laterally offset feet 112 which :sis

engage thelwire to'press- 1t down against the side of the bundle. These feet may be grooved on their under edges to retain the `wirewhen theyare clamped thereon; the clamps are solocated that 'when moved to' functional position, theffeet 112 clamp the wire against the bundle Vat the corner which is udjaeent the twister head.

Pivotally connected with each of the clumps lare one end of links 114, the outer ends of which pivotally connect with rocker arms 115 that are pivotally fixed to the stationary ring 15. The vrockers each comprise' a` triangular member 116 having pivotal mounting as at 117 and rollers 11S ythereto. As .the outer i the lclarnpsto position and 119, carried at the two opposite corners thereof. 4

Fig. 1 shows the two clamps in withdrawn postionpand the` relation of the sector 110 ring starts torevolve the forward end of the sector 110 is brought intoengagement, with the roller 118 ofthe first clamp mechanism riding thereover and rocking the plate 11G on itsr mounting, thus 115 -'to move to position to carrythe .link is illustrated vlin Fig. ,11. As the ring 18 continues to re\*olve,o1')eri ition of the second or vside clamp is likewise effected bringing as shown in Fig. 12. The clamps are retained yieldingly in their clamped or open positions byr means of springs 120 wound about rods 121 which have-pivotal connection with the arms 115 and are'slidable at their outer ends through revolubleimembers 122 fixed to the station'- ary ring 15. The springs bearing at their opposite ends against the rod mountings.A the clutches y'sufficiently to disengage' the The outer ring stops' at such a position the slots 98 and 100 of the rotatable Vhead members to extend' centrally therethrough and closely adjacent the primary end of the v wire. Shortly' after 'starting of the inner -ring the twisting operation takes place.` This is accomplished by meansy of the revolving of of the wire about the main strand, the head being revolved by the meshing of the segment gear 21 carried by the inner ring 2()v the' inner together, the wire which extends throughv the twister is severed, as before described,

andA the'ends ofthe twisted' strands are draign beneath the baling strand by means of the of a tucker mechanism particularly described in Figs. 19 to 23 inclusive, thereby to strengthen the tie and also give protection to workmen handling the bundles.

The tucker mechanism is supported by a vthetwister head to carry the secured end bracket 125 which may be supportedfrom vone of the standards 12. The tucker comprises a curved finger 126 pivotally mounted on a shaft 127 to which shaft isvsecured a gear pinion" 128 with which engages a rack bar' 129, that is slidably mounted in the bracket to thereby oscillate rthe finger 126 on its pivot. The end of the rack has a roller 130 mounted thereon which is adapted to pass within a. cam slot 131 in the plate carried by the inner rotative ring 20.

The position of the finger126, while the wire is being passed about the bundle and until the cutting is done, is shown in Fig. 20. This'shows the wire drawn across the finger and extending between its ends and its pivotal point. v

As the cam 105 movesrforward, the rack roller 130 passes into the slot 131 at the end which is uppermost in Figures 20 to,l 2 3 and a curve 132'tlierein carries the-'ref :k'arearwardly to swing the' tip'end ofthe linger left-handedly or upwardly,'so that a laterally projecting hook 133v at the end thereof will be sprung back of the twisted portion of the strands, as shown in Figs.'21 and23. Continued movement of the cam causes the' curve' 132 to move the rack in the opposite direction thereby carrying the finger 126 right-handedly or downwardly', thus to drawposition;

finger again to neutral position as the cam disengages the roller.

While the tucker is in operation the twister head remains stationary, this being due to the fact that during this time a blank or untoothed portion 135 of the ring 21 is passing by the twister head. The cam 105 is fixed to the blank part of the geared ring 21 so that the cutting of the wire and tucking of the twisted ends starts as soon as twisting is completed.

As the inner ring continues to revolve, cams 140-141 engage respectively with the rollers 119 of the upper and lower, rocker members to actuate the same suiiiciently to swing them past the dead centers, whereupon the springs 120 will move the clamps back to open position.

As the inner ring approaches a completev revolution, a cam 146 carried thereby, shown in Figs. 1 and 4, engages the roller 59', of the lever 59. -Again rocking the lever to move the clutches back to their first driving position, to stop revolving the inner ring and resume driving of the outer ring, so as to bring the latter back to its initial The machine is lthen stopped b` engagement of a cam 17 5 (Figs. 1 and 4 with the roller 58 on the lever 58 which shifts the clutches 41 and 42 to neutral position.

It will be mentioned here that during the time of operation of the tucker, the twister headremains in such position that the slot 100 faces outwardly, but, just prior to final turning of the outer ring, the twister head is given three-fourths of a turn by means of a short geared portion 148 immediately following the blank portion 135, so by engagement of its inner gear 92 with the segment ear section 148, whereby the slot 100 will ace in the direction of travel of the ring'and the wire may pass therefrom, butatthe initial movement ofthe outer ring on the following tyingv operation, the head is given one-half revolution by a short toothed section 150 carried by the sector 110 and engaging the gear 92, so that the head will be 1n position to 'receive the wire as it encloses the bundle. v

When a shift of-the clutches is made from one extreme to the other, it is desirable that the released clutch be stopped as quickly as ossible and this is accomplished by mountmg friction blocks 152 adjustable in the brackets 29---30` against 'which the clutches are moved when shifted from driving relation with the pulley wheel and the frictional contact causes almost immediate stoppage of rotation.

The clutches, when occupying released, driving or neutral position, are yieldingly retained in such set position by means of' mechanism particularly illustrated in Figs.

4, 6 and 7. This mechanism comprises ail v56and at its lower end extends slidably through a horizontal pin 160 that is revolubly mounted between lspaced arms 161 -extending upwardly from the sleeve 50, iixedly secured relative to the clutch'shifting lever 54. A spring 162 surrounds the post 158 and bears against the-collar 159 and pin 1 60 with suiiicient pressure to hold the clutches in driving contact when shifted to either position.

With the parts of the machine constructed and assembled as described, it is apparent that an operation will be started by pressure on the Vfoot lever which moves the clutch 41 into driving contact to revolve the outer ring. Revolving of the outer ring causes first the bundle to be clamped in position, second'the wrapping of the wire about the bundle and actuation of the clamping` arms to press the wire against the bundle. The clutches are then shifted by the cams 106 and the inner ring starts to revolve. This causes the twister head to rotate yto twist the wire and as the cam 105 moves past the twister head and tucker it actuates the wire cutter. and tucker, on final movement of the ring the'clamps are released and the twister head turned to such position that the wire may pass therefrom. Final movement of the outer ring brings the cam 175 into position to shift the clutches to neutral position to stop the machine simultaneously, as the ca m 65 moves into functional position to release the bundle from clamped position.

yWhen one wire has been placed about the bundle and secured, the bundle may be moved along to have another wire placed about it and this be repeated as often as necessary. The bundlel is moved in the same machine, shifting for adding additional ties' and in taking it out of the wheel.

What I claim as my invent-ion and desire to secure by Letters Patent-ofthe United States is: 1. In a bundle tying machine, bundle holding means, a rotatably mounted ring surrounding the bundle holding means and 'carrying a coil of binding wire to also sur- `forward direction when putting it into the ring surroundingv the bundle, a wire holding means carried by said ring, and a wire twister cooperating with said wire carrier.
