MACHINE FOR MAKING WIRE-BALE-TIE LOOPS.

To all whom it mayy concern: n

Be it known that I, RowLAND J. DARNELL, a citizen of the Unit-ed States, residing at Memphis, in the county of Shelby and State of Tennessee, have invented certain new and useful Improvements in Machines for Making VVire-Bale-Tie Loops, of which the following is a specification. y

My invention relates kto a machine for lmaking wire bale-tie loops, more especially` to such a machine inwhich` the wire shall be fed in automatically the required length, cut,'a loop formed on the end of the wire from which the piece has vbeen cut, then the wire further fed into the machine therequired-distance and again cut, repeating the operations in successive cyclesvof the machines action. i

VItis an especia-l object of my invention to provide a looping device which shall form on.. the end of the wire a double coil loop, said loop being finished by wrapping the end of the wire cleanly severaltimes about the wire shank, in combination with means for actuating the looping mechanism and thereafter actuating feeding and cutting mechanism so that the series ofv kopera-tions l is automatic, correlated, and continuous, and

a high speed in the manufactureof the loops may be attained. i

' The full objects and advantages of my invention will appear infconnection with the detailed description thereof and are particularly pointed out in the claims.

In the drawings, illustrating the applica-y tion of my invention in one forum-Figure -1`1s a plan view of my machine. Fig. 2 is a longitudinal section from front to rear thereof. F ig. 3 is a transverse sectional view of a portion of the Vmachine showing the cam shaft and related parts viewedy toward the front of the machine. Fig. L tis a .detail view of the intermittent gear feed rmechanism. Figs. 5 and 6 are views of wing-cams and cooperating shift-ing members actuated thereby. Fig. 7 is a view of acompleted bale-tie made on my machine.

In the practice of the artto which my invention relates, it has been customary to form loops by twisting together the return h end of the wire and the vshank of the wire,

both members being twistedy or coiled about the other. This involves a yweakened pointy 1 Specification of Letters Patent. Application ied April 8, 1.912." Serial No. 689,301.

in the wir@ Shank itself which may break under excessive strain. Loops have been formedv 1n somewhat the manner 1n which I form my loops by mechanism operated largely by hand, entirely so as regards the feed of the wires into the machine. In machines of this type where the wires have torbe fed` in by hand,-they mustA be cut into the proper'lengths in advance of such feeding,` and the operation of feeding them in onek atk a` time by hand is necessarily vrslow and vproduces imperfect results. One of the in the fact that the feed ofthe wire is from Patented Dec.y 24,1912.

e5 primary advantagesof 'my machine resides a coil as it comes from the factory and is i absolutely continuous so that the loops are formed, the wires fed forward vthe proper distance and then out off and delivered from the machine by an automatic and continuous series of operations. The machine, therefore, can be driven at a high rate of speed andwill operate to loop and deliver a maximum of near one hundred bale-ties perminlvute'. I provide means for varyin the rate offeed 1n this mechanism whloi enables bale-ties of different lengt-hs to be manufactured.

The frame of my vkmachine comprises pref-V erably a single casting formed of a base n membery 10 and a series of vertical bearing posts or standards which will be described in connection with the parts supported thereby. (In vbearings 11 and 12 formed in' two such posts is journaled a shaft 13 provided with fast and lloose pulleys 14 and 15 by which the mechanism of the machine is driven. A spurV gear 16 on the end of shaft 13 meshes with a spur gear on a short shaft held in bearings 18 and `19 in the tops of verticalfstandards 20 vand 21 positioned in such proximity as to leave space between v them only for the gear 17.A The shaft in bearings 18 andi19` has formed on opposite ends thereoffand' extendingjust outside of bearings 18 and 19, bevelgears 22 and 23,

respectively. The bevel gear 23 meshes with va `bevel gear 24: on an oblique shaft 25 held in oblique bearings 26 and 27 in kthe ends of standards 28 and 29.

Upony the lower y end of shaft` 25 isa bevel gear 30 meshing' with a bevel gear 31 on a shaft 32 mounted in bearings y34C, 35, 436, 37, and 38 formed in short;standardsv provided kfor that purpose, the shaft 32 extending transversely entirely across the machine near the front or delivery end thereof. Between bearings 37 and 38 near the end of shaft 32 farthest removed from gear 31 is a segment gear 39, formed, as shown in Fig. 4, of a gear segment proper 40 and an untoothed sect-ion 41, said sections being shown as cast separately and secured together by means of bolts 42 and 43 although it is obvious t-hat the gear may be cast in one piece, the form shown being somewhat simpler in finishing. A short shaft 44 is mounted in bearings 45 and 46 in upright standards 47 and 48, said shafthaving thereon between said standards a spur gear 49 provided with a long tooth 50, said long tooth having a circular face adapted to engage the face of the section 41 of mutilated gear 39 which thereby holds gear 49 and shaft 44 in a definitely fixed position. `When the teeth on section 40 come around to said wide tooth 50 they will be caused to mesh with the teeth on gear 49 and said gear and shaft 44 will be turned a complete revolution by the gear segment 40, the peripheral extent of the toothed portions of both gears 39 and 49 being equal. The rim is cut away as indicated at 51 in Fig. 4 to permit the tooth 50 to pass from locking engagement with the st-raight rim of section 41. Shaft 44 is extended beyond bearing 46 as indicated at 52 and upon such extended portion a spur gear 53 is removably secured by means of a nut 54. In a bearing 55 in the top of a standard 56 is journaled a short shaft 57 having removably secured thereto by means of nut 58 an idler spur gear 59 meshing with spur gear 53 and also with a spur gear 60 removably secured by a nut 61 on the extended end 62 of a shaft 63 mounted in bearings 64 and 65 in the tops of standards 66 and 67.

The shaft 63 is the main feed shaft of the machine and it will be noted that this shaft is driven from the cam shaft 32, which cam shaft controls the movements of the loop-forming mechanisms. The cam shaft 32 is constantly driven from shaft 25, but the shaft 63 being actuated by thevsegment gear 39 on shaft 32 is intermittently driven, the combination being such that shaft 63 will be rotated ywhile shaft 32 is making onehalf revolution, the other' half of the revolution of shaft 32 being occupied in actuating the loop-forming and cutting meehanisms hereinafter described. As the gears 53, 59 and 60 are all removable, it will be obvious that by changing these gears the extent of revolution of shaft 63 for each actuating semi-rotation of shaft 32 may be varied as desired for feeding different lengths of bale-ties. The shaft 63 is formed with an enlarged shouldered portion 68. Secured against the shoulders of the enlarged portion 68 by means of a washer sleeve 69 spiral gear 70 and nut 71 on shaft 63 is a feeding disk 72 provided wit-h a peripheral groove 73 which will preferably be V-shaped so as to grip the wire as it is fed through. Secured against the other shoulder of the enlarged portion 68 by means of a nut 74 on shaft- 63 is a spiral gear 75 similar to spiral gear 70. Spiral gear 70 meshes with a spiral gear 76 on a vertical shaft 77 held in bearings 78 on each side of gear 76 in horizontally projecting brackets on one arm 79 of a stand 80 secured to basemeinber 10, the arm 79 being similar to the other of said arms 81 shown in elevation in Fig. 2. The gear meshes with a gear 82 on a shaft 83 held in bearings 84 in the horizontal brackets 85 of the arm 81, as clearly shown in Fig. 2. Secured to shaft 83, so as to have rotation in a vertical plane, by means of a nut 86 is a grooved disk 87 similar to the disk 72, a grooved disk 88 being secured to shaft 77 in exactly the same manner that disk 87 is secured to shaft 83. The bearing blocks 78 and 84 are secured in position by means of set screws 89 and 90 as clearly shown in Fig. 1. The feed disks 87 and 88 extend in a common horizontal plane at right angles to the plane of the disk 72, and have their peripheries movable in such close proximity as to firmly grip a wire between the walls of the V-shaped grooves in the peripheries of these members, the set bolts 89 and 90 permitting adjustment of these feeding disks relatively to accommodate them to wires of different sizes. As shown in Fig. 2, a coperating feed disk 91 similar to and in the same plane with the disk 72 is mounted upon a shaft 92 in movable bearings 93 and 94 slidable in ways 95 formed in standards 96 and 97 extending upwardly from the base member 10, the bearings 93 being forced upwardly so as to cause the periphery of feed disk 91 yieldingly to engage the periphery of feed disks 72 by means of springs 98 seated between said bearing blocks and a supporting block 99 adjustably carried by bolts 100 and 101 extending through lugs 102-103 on standards 96 and threaded through the extended ends of block 99. By screwing up on bolts 100 and 101 the pressure of the feed disk 91 against feed disk 72 may be varied to accommodate the feeding device to the character of wire being fed through. Secured in a vertical plane to the side of the standard arm 81 are a series of three straightening guide disks 104 which are formed with edge grooves 105 as clearly indicated in Fig. 1. Upon a horizontal platform on the stand are secured so as to rotate in a common horizontal plane a similar series of straightening feed rollers 106. The wire coming from reel 107 on stand 108, therefore, must first pass between rollers 106 which straighten it in a horizontal plane and guide it between rollers 104 which straighten it in a verticalplane and in turnx guide it between feed disks 87 and 88 positively rotatedto grip the wire in a horizontal plane and forward it between-' feedrk disks 72 and 91, where the wire is grippedl y so that the wire is positively gripped and n wire accurately, which is absolutely essen` fed in both horizontal and vertical planes,

which taken in connection with the V-` shaped form of the peripheral groove 73 with which all of the feed disksr are provided, positively feeds the 7 wire forward without anyslippage exactly kthe same Adistance at each,` cycle of operation regardless of the speed at which the machine is Lbeing driven. It is the special object of thisv fea-K ture of my invention that the wire which yconnesfrom the coil and is `always more orl less bent and kinked shall be straightened,

fed, and cut off in fixedy lengths while per mitting the machine to run at high speed.`

For'ins'tance, when this machine is operating to make fro-1n sixty to seventy bale-ties per'minute, the wire whilebeing fed may travel at a rate ofoverva mile a minute. -It will be apparent that nothing excepting an absolutely positive and reliable feed can be* depended upon to measure the lengths of tial in an eflicient machine for the purpose,

this vbeing especially true ,whenL it is called to mindl that the n' feeding device is intermittent, its momentum being checked and,

gained'at each cycle ofoperation, at which time there would be great liabilityr ofslippage and irregularity. 'n

f The cam shaft "32 hasthereon a series of cams which will later be described forautomatically presenting the loop-forming mechn anisms to the proper .point for performing their functions duringv the time feeding is not taking place. This arrangement, therefore, strictly correlatesy the feeding of the length of wire, the cutting of the same which also is operated from cam shaft 32, and forming of the loop, the complete cycle of operations always taking place at each full revolution of cam shaft 32. That is every time that cam shaft 32 is rotated once'a baletie is looped, drawn out, cut off and discharged from the machine.`

vAs the wire 109 comes from the last set o feed disks 72 and 91, it is passed through a hollow mandrel or shaft 110 which is supported longitudinally of the machine in bearings 111 and 112 formed in upright standards 113 and 114. The hollow shaft` 110 has thereon a collar'115 rengaged by a washer 116 between which and bearing 111 4 is a spiral spring 117 whichwill push the they said shaft is forced yback against the.`

pressure of spring 117 by means provided for that purpose. A spur gear 118 is rota tably secured to the shaft 110, and between `said .spur gear and a collar 119 adjacent the end of the shaft is journaled the ring 120 of a yfloating shifter 121 provided yat its lower depending end with a roller 122 engaged by a `rface cam 123 onthe shaft `32.

The cam 123, as shown in Fig. 2, has for the major rpartfof its circumference a cylinydrical face 124 of sufficient height to hold the shifter 121 and with it the shaft 110 yin theirrearward position, as indicated in v`face 126 which progressively pushes back shaft 110, the reason for which will be hereinafter stated. To prevent floating shifter v,121 turning with shaft 110 there issecured to thesaid-shifter above the ring 120 a bar arm 127 adapted to slide between lugs 128 on the top of standard 114. 'It is obvious that securing bar 127 to standardv 114 so as v121 and permitting the shifter to slide along the bar would serve the same purpose. The

spur.l gear 118 is preferably a wide gear in mesh with an idler 129 carried by a short shaft'130 journaled in bearings in the ends of two standards 131, 132, the idler 129 in turn ymeshing with a'spur gear 133 yon a shaft 134 journaled in bearings in the ends `toextend'between lugs on the top of shifter f of similar upright standards 135, 136, the f shaft 134 having thereon intermediate the said uprights a bevel gear 137 meshing with bevel gear 22. Through this arrangement of gearing, therefore, the hollowrshaft 110 is constantly driven fromy the bevel gear 22,

the movement of the shaft longitudinally, -f

above described, being along the spur' gear rconnection and, therefore, 1n no way interfering with the continuous ydrive of shaft Journaled in bearings 138 and 139 in up- y right standards 140 and 141 so as to extend parallel with and directly above the cam shaft4 32 is a shaft 142 having secured on the end thereof a spur gear 143 in'mesh with the spur gear 17, said gear 17 being suinciently wide to permit longitudinal movement of shaft 142 to the desired extent with#` out breaking the meshing engagement thereof. The shaft 142 is provided with collars 144 and 145 between which is journaled the ring 146 of a shifter 147 having on theend thereof a roller 148adapted to be engaged by a wing cam 149 secured by a collar 150 to the cam vshaft 32. To the upper part of between lugs 152 so as to slide freely there-y betweenand hold the shifter from turning shifter 147 is secured a bar '151 extending with the shaft. A springf153-extends'be-l1'30 tween washers 154 and 155 loose on shaft 142 and normally presses the shaft so as to hold the same in the position shown in Fig. 3. rhe wing cam 149 is shown most clearly in Fig. 6 and is adapted through shifter 147 to force shaft 142 forward the desired extent during a little less than one-fourth of the revolution of cam shaft 32.

Mounted to slide in bearings 156, 157 on the ends of upright standards 158, 159 is a square shaft 160 having on the end thereof a mandrel pin 161. The shaft- s 160 and 142 are held in alinement and the mandrel 161 alines with a central hole 162 in the end of shaft 142 so that when both the shaft 160 and the shaft 142 are brought to their' most forward position the mandrel 161 will be positioned in the hole 162. Keyed to the shaft 160 is the ring 163 of a shifter 164 having thereon a roller 165 positioned to be engaged by wing cam 166 carried by a collar 167 fast on cam shaft 32. As shown most clearly in Fig. 5, the wing cam 166 is of such extent as to engage roller 165 and hold shaft 160 and mandrel 161 in retracted position for slightly more than one-half of a complete revolution of cam shaft 32, and when the shaft 160 is not so retracted it is held in its forward position by means of a spring 168 positioned between the collar 163 and the bearing 157.

As clearly shown in Fig. 2, the wire after passing through hollow shaft 110 extends beneath the point of mandrel 161 and beneath a stationary shear blade 169 removably secured by bolts 170, 171 to upright posts 172, 173 carried by a frame 174 adjustably secured to base member 10 by means of a bolt 175 extending through a slot 176 in the horizontal base 177 of said frame member. The posts or standards 172 and 173 each has on the inner face thereof a groove 178 and 179, respectively, in which slide correspondingly shaped projections 180 and 181 on a block 182. vRemovably secured to the block 182 is a shear blade 183 adapted to coperate with the stationary shear blade 169. Extending beneath block 182 is the end of a lever 184 which is pivotally connected at 185 to the standard 114 being bent as indicated at 186 to carry the lever above a cam 187 on the cam shaft 32 adjacent cam 123 and between standards 141 and 158. The shape of cam 187 is indicated in dotted lines in Fig. 2 and is such that the lever 184 is forced up carrying with it block 182 and causing shears 169 and 183 to cut the wire immediately after the feeding action produced by gear segment 40 on shaft 32 has been terminated.

The complete automatic operation of my device is as follows. Supposing the loop ing action to have just been completed and the gear segment 40 on shaft 32 to bejust engaging the side of tooth 50 on gear 49,

during Athe succeeding half revolution of shaft 32, through gears 49 and 53, idler 59, spur gear 60 and spiral gears 70 and 75 on shaft 63 and spiral gears 76 and 82 on shafts 77 and 83, the feed disks 87 and 88, the feed disk 72 and with it feed disk 91 will be positively rotated to measure and feed forward a piece of wire to form a baletie of t-he'length desired. As cam shaft 32 has been revolved the high part on cam 187 is brought into engagement with arm 184 by which block 182 is lifted to shear the wire just at the moment when the last tooth of gear segment 40 has left gear 49 and feeding action is stopped by engagement of gear tooth 50 with the untoothed rim of segment 41. At the same time wing cam 166 will have been taken from engagement with roller 165 on shifter 164 so that spring 168 will force shaft 160 and mandrel 161 inwardly above the wire 109. There will then be a short section of wire 188 extending from mandrel 161 to the point where the wire was sheared adjacent shear member 169. Upon the end of shaft 142 is a hook 189 which as Lshown in Fig. 1 is at the bottom of the shaft so that when the shaft is pushed forward said hook will come be neath` the wire section 188 and rotation of the hook will wrap the wire about the mandrel 161. The cam shaft 132 will immediately after the wire is cut and mandrel 161 is projected bring wing cam 149 into engagement with roller 148 and through shifter 1.47 will force shaft 142 inwardly against the pressure of spring 153 until mandrel 161 enters hole 162 and hook 189 comes beneath wire end 188. The wing cam 149 is of such size and is so timed in action relative to the drive of shaft 142 that the hook 189 will make two complete turns before the cam 149 passes off of roller 148 and the shaft 142 is retracted by spring 153. Two full loops of wire, therefore, are laid upon the mandrel 161 and as the hook 189 is retracted from the mandrel the remaining end of the wire will be left extending at an angle outwardly from mandrel 161 as indicated at 190 in Fig. 2. By this time cam shaft 32 will have rotated to the position shown in Fig. 2 and a slight further rotation will bring roller 122 opposite the low portion 125 which will permit spring 117 to force shaft 110 inwardly. As shown in Fig. 1, a hook 191 similar to hook 189 is formed on the end of shaft 110. vWhen, therefore, the shaft is pressed forward this hook will engage the end 190 of the wire extending at approximately right angles to the main shank of wire 109 and wrap said end several times about the main shank of wire 109. The adjustment of the stand 174 by means of bolt 175 in slot 176 will have been such that this last wrapping movement will completely use up the end 188 origid v l `time through -thetoothed vand non-toothed' ing` the mandrel 161 from the double coil of' wire. formed thereabout, and immediatelyr after said withdrawal gear segment 40 will again have come into engagement with ytooth 50 on gear 49 and the feeding action of another cycle of operations will be begun.

From the above it will be seeny that the hooks y189 and 191 which perform looping operation are constantly rot-ated, but the control of-.said hooks for' positioning them toV effect their function and yalso the control of the mandrel 161 for positioning it to receive theiloop and for withdrawing it `fromsaid loop isv effected entirely bythe rotationof ,cam shaft 82 which at the same segments 40 and 41 determines the feed of the wire in absolutely cordinated'relation to the' looping mechanism and the shearing device, which is also controlled from the cam shaft 32. A single member,therefore,

is provided for automatically controlling the operations for" projecting ,the mandrel,

j forming-the loopfon the mandrel, wrapping the end of the wire about the shank ofthe wire, measuring and feeding the wire of the proper length through the machine and then shearing the same. In view of the positive ness and accuracy of the feed and the above indicated unitarycontrol of all of theoperations of the machine, the Amachine is not only rendered automatic in the fullest sense of the term but is automatic to such an extent as to Vrequire practically no attention from an operator and to need merely an unskilled attendant for removing and caring Vfor they bale-ties asformed and setting up a new roll of wire as the preceding wire is used up. Economies in operation of the machine will bey apparent and in-view of the results obtained, the machine is simple in structure and economical to build.
