Application inea June 13, 1914. serial No. 844,894.

To all whom t may concern:

Be it known that I, ROGERS M. WARWICK, citizen of the United States, residing at Chicago, in the county of Cook and State of Illinois, have invented certain new and use-- ful Improvements in Tying-Machines, and I do hereby declare the following to be a full, clear, and eXact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

My invention relates to machines for making wire ties, being particularly suited for making the class of wire ties used with valve-filled bags, which bags are commonly used for shipping cement, grain, lime and the like. In tying such bags with wire, it has heretofore been customary to 'use wires cut to a predetermined length, such Wires being veither in the form of rings, or or' straight lengths equipped at each en'd with suitable formations for gripping the said ends to manipulate them during the twist- In either case, the length of wire used has to be the maximum size needed for the tying of the general size and type of bag upon which the tie is used, as the actual periphery 0f the puckered mouth of the bag will vary considerably in the same lot of bags; consequently the use of ties affording a sufiicient length to allow for such variations has meant a waste of wire for a large proportion of the bagsactually tied therewith. Moreover, the joining of the ends of ties into an endless ring by weld ing the said ends introduces an uncertain factor of strength; while equipping the ends of a straight piece of tie wire with easily gripped formations increases the labor required in handling suoli ties. In any case, the use of such ties also introduces the personal element of the operator in delermining the tension put upon the wire during the twisting, and if this tension should be `eX cessive, it may easily lead to a breakage of the wire while the bag is being shipped, or

to a likewise objectionable breaking of the.

wire when the tie is being untwisted for opening the bag. 'Moreoven the use of ties of the class above described, involves. the previous preparation and storing of the same and a separate handling of each tie when being appliedl thereby leaving the operator free to use only one hand in puckering the mouth of the bag and placing the loop in position for being tied.

The general object of my invention is to provide a tie-forming machine which will not require any previous cutting or preparation of the tie wire; which will manipulate the wire itself Without requiring the latter to be handled or even touched by the operator, thereby leaving the operator free to use both hands in rapidly and accuratelypuckering and handling the mouth of the bag; which will automatically` adjust the length of the Wire used for each individual bag to the minimum actually required for the same; which will tie each bag with the same tension upon the Wire, and which will enable the desired tension to be readily adjustable; which will form the ties from a continuous `supply of Wire and which will straighten out any kinks in the said wire before forming thc corresponding portions thereof into the tie; which will sever the wire required for each tie from the continuous supply of wire; and which will form the free ends of the tie wire into an auxiliary loop formation whereby the same may readily `be manipulated when the mouth of the bag is to be untied. Further objects of my invent-ion are to provide simple mechanism for feeding the wire, and means for adjusting the amount of the said feed according to the peripheral size of the mouth of the bag and the desired tension of the wire tied around the said mouth of the bag; for guiding the wire in a loop formation around the mouth of a bag; for gripping the free end of the wire after being thus guided into loop formation;l for releasing the loop wire from the guide means to permit a contraction of the said loop, for twisting the contracted loop Wire disposed about the mouth of the bag; and for relatively moving the guide means with respect to the bag to permit the proper positioning of the bag for tying and the removal of the bag afterthe tie has been formed. Other objects will appear from the following specification and from, ,the accompanying drawings, in which- Figure 1 is a plan view of a machine em'- bodying my invention and adapted for tying the nuckered mouths of bags.

Fig. 2 is a side elevation of the same.

vthrough the Fig. 3 is a front elevation of the same. Fig. 4 is a fragmentary view of portions of the wire-retracting mechanism.

Fig.'5 is a vertical section through Figs. 1 .and 2along the line 5-5.

Fig.' 6is a fragmentary view showing the' drawings.

Fig. 12 is an enlarged vertical. section guide means of Fig. 1 along the line 12-12. l I i In the'embodiment `of the drawings, the machine of my invention includes a base plate or'talble 1 equippedat one end with an entrance tube 2 through which the wire 3.

enters from any suitable source of supply.

From the tube' 2 the wire 3- passes over a plate 4 equipped with a' pair o vertical pivots 5 carrying cams v6, which members 6 normally present cam surfaces separated by a' spaceslightly O'reater than the diameter of the wire 3. cam surfaces 7 of the said pivot `members 6,

the wire passes through a tube formed by opposedA grooves in hardened steelV blocks 8,

which grooves are so disposed to straighten out any kinks in the wire. The wire then passes between a pair of feed rollers 9 mounted on'vertical shafts 10 carried by the base 1 and thereafter into 'a tube 11 .forming part of a vseries of guides for guidmg the free end of the said wire about themouth portion ofthe bag when the said wireA is fed forwardly by means of the feed rollers 9. In the drawings, the said guide means' comprise a tube 11 extending substantially to theforward end of the base plate 1 and 'Y a pair of

curved guide members

12 and 13, the forward ends of which guide members normally contact withceach other so that the said members will coact to ailorda substantially horseshoe-shaped tubular guide forthe said wire. The guide member 12 first enteredby the wire after the latter leaves the tube 11 is preferably made of resilient lmaterial and equipped with a slot-facing the guide member 13 but slightly smaller in di ameter vthan-the wire 3. The other guide member 13 lis preferably made of two hori- I U zontally separated elements 13 and 13', both of which elements are pivoted on a hori- 'zon'tal shaft 14, and thefinwardly disposed edges ofY which elements are normally subfter passing between"v the stantially in contact witheach other. Each of the said members l2 and 13 is carried by an arm 15 mounted upon a vertical pivot 16 and having a portion adapted to be engaged by a dog 17 carried lby a vertical shaft 18, the said dog 17 being preferably in the form of a screw to ermit a ready adjustment of its length. ssociated with each of the said pivoted arms 15 is a tension spring 19 secured at one end to a pin 201 carried by the |base 1 of the machine and continuously tending to press the said arm 15 against the dog 17 and to move the said arm when the said dog is swung out of the way by a partial rotation of the shaft 18.

To effect the forward feed of the wire, which in each case starts with its free end at the forward end of the guide tube 11, I provide the feed wheels' 9 with cylindrical por` tions cut awayfor a part of their periphery, the integral peripheral portion being of a length equal to the maximum length of wire required for forming the general size and type of tie which is to be made by my machine. Mounted at some distance above the Wire-guiding means heretofore describedand supported by brackets or

standards

21 and 22 carried by the base 1 is a shaft 23 extending longitudinally of the machine,

which shaft is continuouslyy rotated when the machine is in operation. Secured to the said shaft near the forward end there- Aof is a disk 24 carrying a toothedsegment 'a companion bevel gear 28 and a spur gear 29 toa gear 30 rigid with respect to one of the feed wheels 9. A'companion to the latter feed lwheel preferably also has a gear wheel 3.1 rigidV therewith and intermeshing the teeth of the lsaid'whee1g30, so that the saidy feedLwheels 9 will at all times rotate I in unison but in opposite directions. It will .be evident from Flg. -5 that as'the teeth of the segment 25 correspond to .only 'a` small portion of the circumference of the wheel 24,- the Wire-feeding mechanism actuated by 1 the said segment will only be in operation during a fraction bf each revolution of the shaft 23 carrying toothed segment 2o.

The distance between tions of the two feed .Wheels 9 corresponds the said disk 24 Yand Aapproxim'ately'to the diameter of. the -wire 3, so that when the said feed wheels are-ro tated, the will'coperate to propel the wire 3 for a istan'ce corres ending to thelperipheral length ofA the said opposed portions of the 'feed rollers, whereupon the guide the cylindrical por:

members 12-and 13 will cause the forward Y portion'of the wire.l to be disposed loop formation` (as indicated in and will feed the tip ofthe wire. into a ioriz'ontal ist bore 32 in the head 33 carrying the guide tube l1. The said head is rotatably mounted in a journal 34 carried by the base l, the

axis of said journal being in alinement with' the rear portion of the Guidetube 11 and the entrance tube 2 of tie machine. The member 33 carries at one end a pinion 34 adapted to intermesh with teeth 35 disposed upon a ortionof the periphery of the disk 24, where y the said member 33 (which forms the twisting head of the machine) will be rotated several times during each rotation of the shaft 23 carrying the disk equipped with the peripheral teeth 35. To prevent the extreme tip of the wire from slipping out of the said bore 32 While the head 33 is being rotated to twist the ends of the wire loop about each other, I preferably provide a pawl 36 pivotally mounted in the forward end of the twisting head 33 adjacent to the said bore 32, the said pawl being continuously moved in one direction by a spring 37 and being equipped with a forwardly projecting lug 38. When the free end of the wire is being fed into the bore 32, it moves the said pawl 36 slightly against thek pressure of the spring 37, after which the said spring and pawl coperate to prevent a retraction of the tip portion of the wire from the said bore 32. However, the said tip may be released by moving the pawl 36 through pressure on the lug 38, for which purpose I provide a plunger 39 carried by an arbor-carrying slide 40 which will be described hereinafter, and which plunger is adapted to engage the said lug 38 to swing the pawl 36 about its pivot and release the tip of the wire.

When the machine is to be used for tying the mouths of bags, I preferably equip the base 1 with a forwardly curved projection 42 which will aid the operator of the machine in placing the bag in the desired position, and against which the mouth of the bag will 'bear when the wire looped around the said mouth is being tightened by a twisting operation. It will be obvious, h`owever, that the strain thus put upon the thrust member 42 and upon the wire of the loop while the latter is being twisted will vary with any variation in the exterior diameter of the mouth portion of the bag, and likewise with the difference in compressibility afforded by bags of substantially the same size but made ofI different materials.

To allow for such variations without, using a surplus of wire and without imposing an excessive strain upon the wire forming the loop, I provide spring-regulated means for contracting the loop to the necessary size and tension required for each particular bag before performing the twisting operation. For this purpose, I mount upon the shaft 23 near the rear end of the machine a disk 4l equipped upon its forward face with a segmental cam 42 for engaging the head 43 of a tension lever 44 pivotally mounted upon brackets 45 carried by the standard 21 at the rear of the niachine. The lever 44 is preferably formed with a loop portion permitting the shaft 23 to pass freely therethrough and is provided near its lower end 46 with a perforation housing the shank of a bolt 47. The bolt 47 also passes loosely through a perforation in a lever 48 likewise pivoted upon the brackets 45 and equipped at its lower end with a toe portion 49 of sufficient width for simultaneously rengaging upwardly projecting lugs 5() carried respectively by the two cams 6. Surrounding a portion of the shank of the bolt 47 and interposed between the nut 51 of the said bolt and the forward face of the lever 48 is a compression spring 52 which may be adjusted as to its compression by varying the position of the nut 51 upon the said bolt. This spring is normally adjusted to a compression corresponding to a power considerably in excess of that required for moving the cams 6 and forcibly retracting the wire 3 by the engagement thereof between the opposed surfaces of the said cams. Consequently, when the disk 4l is rotated so that the head 43 is moved from the position shown in Fig. 2 to that shown in dotted lines in the same figure. the jointly pivoted levers 44 and 48 will move together as if they had been rigidly bolted to each other. However. as soon as the resistance afforded either by the engagement of the wire loop with the mouth of the big or by the forward pull on the wire caused by the strains of twisting the ends lof the said loop exceeds the pressure for which the. sprin 52 is adjusted, the said spring will permit the lower end of the lever 44 and the adjacent portion of the lever 48 to separate as shown in Fig. 4. Consequently, the extent to which the wire loop is contracted bv the coperating action of the cam 42, levers 44 and 48 and cams 6 will be automatically varied or adjusted for each individual loop which is to be tied; and likewise the retraction of the wire for contracting the loop will be relaxed whenever necessary so as to prevent an overstraining of the wire while the latter is being twisted. A similar automatic loop-tensioning will also be accomplished; v when using my machine for tying the crossed wires 79 of iron rods as used for making concrete reinforcements. in which caseJ the thrust member 80 is provided with grooved tips 81 asshown in Fig. 6.

The shaft 23 also has secured thereto at the forward end of the machine a cam 53 presenting 'a raised portion 54 adapted successively to engage rollers 55 and 56, which rollers are carried respectively by levers 57 and 58 pivotally mounted at the forward end of the framework of the machine. The other ends of the said levers are equipped with forks respectively engaging pins 59 and 60 projecting from horizontally disposed slides 61 and 62 disposedl in guideways at the front of the machine and adapted when moved to engage the free end portions of the wire loop. The slide 62 is equipped upon the edge facing the wire loop with a cutting edge, to sever the adjacent portion of the wire loop from the adjacent part of the supply o'f wire as housed by the tube 11. The forward end of the frame is also equipped with 'vertically disposed guideways 63 housing the slide 40 carrying the arbor 64, the said slide together with the levers 57 and. 58 being normally held in operative position by interconnected springs 65.

To maintain the twisting head of the machine stationary except during the above described twisting operation, I equip a portion of the said twisting head with a peripheral recess 66 adapted to be engaged by a pawl 67 and thereby kept from rotation as long as the said pawl is interlocked therewith. The pawl 67 is carried by a lever 68 pivoted nearl its center upon the framework of the machine and is normally pressed toward the said raised portion of the twisting head by a spring 69. The other end of the lever 68 carries a roller 70 adapted to be engaged by a segmental cam 71 mounted upon the rear of the disk 24, the said engagement serving to rock the said lever so as to disengage the pawl 67 and permit the twisting head to be rotated by the coperation of the teeth 35 and the pinion 34.

The disk 24 also carries upon its rearface two arcuate cam formations 72 and 73 so disposed as substantially simultaneously to engage rollers 74 and 7 5 respectively, the said rollers being mounted at the upper end of bellcranks 76 and 77 terminating in the arms or dogs 17 heretofore described as bearing against the pivoted arms 1-5 which support the members of the substantially horseshoe-shaped guide mechanism. The said formations 72 and 73 are relatively so disposed that they will simultaneously engage and leave the rollers 74 and 75 respectively, thereby spreading simultaneously and closing the

halves

12 and 13 to grasp the object which is to be surrounded by the loop of Y the tie, and thereafter permitting the springs 19 to simultaneously open the same.

- While the resiliency of the jaws of the guide member 12 will readily permit the looped wire to be forcibly drawn out of the and having its tip disposed near a peripheral portion of the disk 24, so that the said tip mayenter a recess 82 in the said disk, thereby temporarily rotating the said pivot 14 and opening the jaws (as shown in Fig. 12), the said jaws being normally held closed by a-spring 83.

It will be obvious from Fig. 11 that the shape of the secondary loo 84 formed by the coperation of the sli e 40 with the

slides

61 and 62 will depend on the shape of the said arbor 64, and that the said auxiliary loop will afford a convenient means for untwistingthe main loop 85 of the tie when the bag is to be opened. However, the formation of the secondary loop may easily be avoided by merely removing the arbor 64 around which the said loop is formed, thereby also adapting my machine for tying objects (like the crossed wires 29 of Fig. 6), where itis not desired to aiford means for untying the main loops. Moreover, it will be evident that the various details of -construction herein disclosed mightbe varied in -many ways without departing from ithe spirit of my invention, hence I do not Wish to be limited to the precise embodiment herewith pictured and described.
