SPECIFICATION forming part of Letters Patent N 0. 652,998, dated July 3, 1900.

' Application filed February 19, 1900. Serial No. 5,747. (No model.)

To all whmn it may concern.-

Be it known that we, FRED H. DANIELS and CLINTON S. MARSHALL, citizens of the United States, residing at Worcester, in the county of Worcester and State of Massachusetts, have invented a new and useful Machine for Making Wire Bale-Ties, of which thefollowing is a specification.

The object of the invention is to provide an improved machine for making the better class of ties intended more especially for cottonbales; and the invention consists in the construction and arrangement of parts hereinafter described and claimed, and illustrated in the accompanying drawings.

IIeretofore in the manufacture of such ties by machinery it has been customary to feed the tie-wires already out into suitablelengths and straightened byanother machine into the eye-forming machine and to feed them one at a time to the eye-forming mechanism. In the present machine the wire is fed forward into the machine continuously from a convenientlylocated coil and is straightened and cut into lengths appropriate for the particular use for which the ties are intended by the machine itself, whereupon the'cut lengths are delivered to the eyeforming devices, the wire at all times being under easy control and requiring no handling from the time the strand leaves the coil until the completed ties are discharged from the machine.

The entire machine is illustrated in the accompanying drawings, forming part of this specification, wherein- Figure l is a top plan view, and Figs. 2 and 3 are respective front and side elevations, of the machine. Fig. 4 is a sectional detail on line 4 40f Figs. Qand 5. Fig. 4 is an enlarged sectional detail on the same line, and Fig. 5is'a vertical sectional detail on the line 5' 5 of'Fig. 4. Fig.0 is a similar view on the line 6 6 of Fig.1. Fig. 7 is a detail of the jaws for gripping the tie-wires. Fig. 8 is a sectional detail. on the hopper for the tie wires and its plunger and spring-rod. Fig. 9 isa detail of the hooks for carrying the tie- Wire down upon the arbor and for discharging the completed ties. Fig. 10 is a detail of from the groove in the receiving-rod. Fig. 11 is a front elevation of the twisting-head. Figs. 12 to 15 are progressive views of the tie in different stages of formation.

Referring to the views, adenotes the main shaft of the machine, journaled in suitable hangers from the bed-plate and having a pin" ionc midway of its length, a band-wheel b on one end and-a hand-wheel b on its other end for turning the machine by hand when occasion requires. The pinion 0 gears with a spur-wheel don a shaft 6, journaled in brackets at one side of the bed of the machine above the shaft on and connected by mitergears f and g to a shaft h, journaled in bearings at the side of the machine and having a spur-gear c' on it meshing with a spur-pinion j on a short shaft :n,-.journaled in standards y yabove and parallel with the shaft it. Fast on the shaft 00, alongside the pinion j, is a speeding spurgear 70, which meshes with a smaller gear Z, mounted on a stud-shaft and gearing with a speed-gear p on the shaft of the lower one of the 'wi re-feeding rolls 17 through the interniediacy of the removable pinion m, secured ma slot 0 in a yoke 12, the pinion m being interchangeable with others of different size forthe purpose of regulating the speed of the feeding-rolls.

,.On the opposite end of the shaft h from the pinion 9 there is a cam and crank-disk 1,

which connects, by means of a pitman 2 with a slide 3, having a gear-rack for the purpose of rotating the coiler, which will be described later on. Also mounted upon this shaft it there is a cam 4, having a peripheral groove 5, which controls a lever 54 for moving the coiler endwise to and fro during the operation of the rack just referredto. Alongside the cam 4 on the shaft it there is an eccentric cam 6, the function of which is to reciprocate a hook for feeding the wires to the coiler and twister, as will be more fully described later on. In the side of the gear-wheel d on the shaft 6 there isa cam-groove 8, in which plays a roller on the end of a slide 9, carrying a gear-rack at its opposite end for the purpose of rotating a twister 7, which will be presently described. On the same shaft e, forward of the gearthe knife and the arm for releasing the wire wheel, are located earns 10 and 11, the former of which operates a knife for cutting the wire into lengths and also has an eccentric groove in its side face for operating the hook or finger 12 on a slide 13 for the purpose of withdrawing the arbor,hereinafter to be described, at the proper time. The cam 11 is for the purpose of operating certain gripping-jaws, to be described later on, and alongside this cam on the shaft e there is a wiper 14, which operates the mechanism for discharging the tie-wires from the hopper in to the twister and coiler.

The several parts and their joint action will be now described with reference to the passage of the wire through the machine.

The wire is denoted by 15 in Figs. 1 and 3. It comes from a coil conveniently located with respect to the machine, and after passing through ordinary straightening-rolls 16 16 passes between the grooved feed-rolls 17 17, which are positively driven by the gearing, hereinbefore described in connection with other intermeshing gears, upon their respective shafts, which are shown in dotted lines in Figs. 3 and 6. Ascrew c and a slide it are provided for raising and lowering the roller end of the upper shaft for the purpose of throwing the wire'feeding mechanism into or out of action. From these feeding-rolls the wire passes straight forward through a guideeye 13 and is delivered into a groove 19 in the under side of a rod 20, which is mounted in brackets in line with the guide. The inner end of the rod,2O is secured to a head 21, supported by the framing of the machine, and the rod extends forwardly in a direction of the wire to the length of the longest ties it is desired to make on the machine. At its outer end, and, if desired, at different points along its length, it is supported by brackets; but as there is no particular novelty in this device per so we have not shown its entire length, but have broken it off in the several views. As clearly shown in Fig. 10, the groove 19 is on the under side of the rod 20, and, except for the holder and dropper 22, would be always open. Mounted in the supports of the rod 20 and parallel therewith is a smaller rod 23, which has at intervals along its length arms 24, reaching down and under the rod 20 and carrying a plate on their outer ends which comes up against the under side of the rod 20 and closes the slot 19. The purpose of this rod is to receive and confine the projected wire and hold the same while the appropriate length for the tie is being cut off. This is done by a knife 25, secured to the end of a pivoted lever 26, operated at its other end by the cam 10 on the shaft c before described. On the extreme end of this lever in front of the knife there is a rack 26, which meshes with a gear-segment 27 on the inner end of the rod 23, the object of this arrangement being to withdraw the holder and dropper 22 from under the slot 19 and permit the length of the wire which has been cut ofi by the action of the knife 25 shearing against the end of the wire-guide 18 to drop into the hopper to be presently described. This hopper is denoted by 27, and it is located below and slightly to one side of the holder and dropper 20, and as the wires are released they fall bodily into the hopper with their ends abutting against the stop-plate 28. The hopper consists simply of vertical jaws 28 29, preferably flared at their upper ends to insure the entrance of the wires and having a space between them suflicient to permit the wires to enter one on top of another, but not wide enough to allow them to pass one another. Preferably the hopper is adapted to receive and hold a number of wires, but in the ordinary operation of the machine the holder and dropper 22 will be so timed and speeded with relation to the other parts as that there shall be only one Wire at a time in the hopper.

After the wire has been out by knife 25 into the proper length for a tie and dropped into the hopper it is pushed laterally by a plunger 30 sidewise along the ledge 32 and delivered into the mouth 33 of a passage-way 34, which will be more fully described later on. The plunger 30 is carried by a slide 31, which is operated by the wiper 14 on the shaft 6, as before described. The passage-way 34 ex tends vertically from the bottom of the hopper a little to one side of the ledge 32, and in a plane perpendicular to the passage-way is journaled in suitable bearings on the bedplate a twister 7, having a slotted head 35 in line with the passage-way. When the wires are delivered into the passage 34 from the hopper by the plunger 30, they are grasped by a vertical sliding hook 36 and carried bodily downward until they rest within the slot of the twister-head. It is important that the wires should always be under control, and for this purpose there is arranged in the jaw 29 of the hopper a plunger 37 in line with the plunger 30 and pressed inward toward the hopper by a spring 38. WVhen the plunger 30 pushes the wire out of the hopper, it is held between the ends of the plungers against escape.

The twister is best shown in Figs. 4 and 11. It consists of the slotted head 35, having a guide-plate 39 on its front end at one side of the slot and a notched plate 40 on the end at the opposite side, the notch being for the purpose of preventing the wire from rising during the action of the coiler. 41 denotes an arbor mounted transversely in the twisterhead and pressed byspring 42, so as to stand normally across the slot 35. On the opposite side of the slot from the arbor and in line therewith the head is provided with an opening 43, and this opening is adapted to receive a coiler 53, journaled in bearings in the bedplate in line therewith at a certain time in the operation of the machine to be presently described. The twister-spindle has an elongated pinion 44' and is driven from the rack 45 on the slide 9 through the intermediacy of the pinion 46, which gears with the rack and has a ratchet-and-pawl connection 47 with a speedingear 48, which gearsdirectly with the pinion of the twister. The rack 45 is operated by the cam-groove 8 in the wheel (1,

as before described, and for the purpose of locking the twister with its slotted head in the correct position to receive wires a slide 49 is operated by a pivoted lever 50 from a cam-flange 51 on the side of the cam 1 for the purpose of engaginga notch 52 in the periphery of the head of thetwister.

Then a tie-Wire is presented to the twister, the slotted head stands in the position indicated in Figs. 4 and 4 and locked in that positionby the means j ust described, The rear end of the wire having been fed into the slot rests upon arbor 41, and at this moment the coiler 53 is projected into the opening 43 through the intermediacy of the pivoted lever 54 and the cam 4 on the shaft it previously described. I The slide 3 is then operated to rotate the coiler by means of its rack 55 and the elongated pinion 56 of the coiler-spindle, and the nib 57 on the end of the coiler takes the wire and wraps it around and around the arbor 41, as indicated in Figs. 12 and 13. During the wrapping of the wire around the arbor the coiler is slowly backed off to enable the strands to be laid evenly on the coiler and not pile up on one another. This backing off of the coiler is very gradual and is effected by the lever 54 through the inclination of the groove 5 in the cam 4. After the coiler has wrapped the wire the requisite number of times around the arbor it is entirely withdrawn from the opening in the head by means of an abrupt jog in the cam-groove 5, and the mechanism for locking the twister-head is also released at this time. The'rack 45 is then operated to rotate the twister for the purpose of forming the twist in the wires, as illustrated in Figs. 14 and 15, after which the arbor is withdrawn'to permit the completed tie to drop out. The finger 12, hereinbefore described as being for the purpose-of withdrawing this arbor, slides in ways in the bed of the machine, and when the twister-head is locked in position it stands in the position indicated in Fig. 4, ready to withdraw the arbor by means of a button 58 on the end of the arbor. When the twister revolves, it carries the arbor with it and releases the button from the finger 12;

but on the completion of the revolution the,

head comes to rest with the finger 12 just under the button, and at this moment the slide 13 is operated by the side groove in the cam 10, before described, to withdraw the arbor and allow the coiled and twisted tie to drop out of the machine.

The passage-way 34 has a spring-press plate 59 for the purpose of controlling the descent of the wires and preventing them from escaping the action of the feeding-hook. This hook is mounted on a slide 60, which works vertically in ways in the machine-frame and is operated -by the cam 6, before described,

through the intermediacy of a spring-held .pivoted lever 61, and the timing of the hook is such that immediately on the delivery of a tie-wire from the hopper by the plunger 30 it seizes it and carries it downwardly into the slot of the twister-head and upon the arbor. The feeding-hook 36 then immediately returns for a new wire, and there is pivoted on the slide 60 a little below the feeding-hook a spring-press discharge-hook 62, whose function is to eject the completed tie from the machine. As the feeding-hook ascends to receive the tie-wire the discharging-hook slips past the wire which at that time is engaged by the twister, and on the descent of the feeding-hook the discharge-hook catches the completed tie and ejects it.

After the eye has been coiled in the wire and immediately before the twister begins to rotate the ends of the wire are gripped some little distance in front of the twister by the jaws 63 64, whose function is to hold them securely during the twisting operation. These jaws occupy a position perpendicular to the path of the wire and slightly to one side of the passage-way 34. The lower one is carried bya slide 65, moving in ways in the bed-plate,

and the upper one is carried by a lever 66,

pivoted on a stud 67, seated in the slide 65. There is a roller on the rear end of this slide which works in a groove 68 in the side of thecam 11, and the two jaws are thereby moved into and out of the path of the wire in the passage-Way 34. The lever 66 is operated by a riser on the periphery of the cam 11 for the purpose of opening and closing the jaw 63 at the proper time.

As the twister-head revolves it is necessary that it should yield toward the jaws where the wires are rigidly held. To accommodate this movement, the spindle 7 is 'adaptedto slide in its journals and has on its rear end a collar 69, between which and the framing reacts a spring 70, which keeps the head normally in its proper position, but allows it to yield under the straining action of the wires being twisted. A stop-plate 71 is provided to limit the rearward movement of the twisterspindle, and in order to insure its return after twisting a roller 7 2 acts against the collar 69 to carry it positively backward. This roller is on the upper end of a pivoted lever 73, which is operated by a side groove in the cam 74, a roller 75 on the side of the lever working in the groove.
