BALE-TIE MACHINE.

SPECIFICATION forming part of Letters Patent lvm-591,532, dated October 12, 1897.

Application filed August 17, 1896.' Serial No. 603,061. (No model.)

.To all whom, it may concern: y.

Be it known thatv I, OWEN K. HARRY, a citizen of the United States, residing at Dallas, in the county of Dallas and State of Texas, have invented a new and Improved Bale-Tie Machine, of which thevfollowing is a specification.

My invention relates to machines for making and counting bale-ties; and the object is tomanufacture at small cost machines which will be compact, not taking up much space, and which will be simple in construction and durable.

The invention consists in the novel construction and arrangement of parts hereinafter fully described, and more particularly pointed out in the claims.

Reference is had to the accompanying drawings, forming a part of this specification.

Figure 1 is a top view of the machine. Fig. 2 is a cross-section through line fr of Fig. 1, looking toward the left. Fig. 3 is a detailed view of the twister, partly in section.

Fig. 4 is a side elevation of the shifting?,

Fig. 7 is a detailed view of the cutter, the casing being in section. Fig. 8 is a top-view of the mechanism for operating the cutter. Fig. 9 is a top view of the device for discharging the ties. Fig. 10 is a side elevation ofthe shifting-wheel, showing dogs attached for shifting the wire-twister. Fig. 11- is a View of the pivoted arm forming the operative means between the twister and the shiftingwheel. matic counting device. Fig. 14 is a side elevation of the mechanism 4for operating the counting device and thetie-discharger. Fig. 15 illustrates the positions of frames G and Hobtained when at `themidd'le of their` course. When at the'end of their course, their positions are justl the reverse of those illustrated in Fig. 14. .I

Similar charactersof reference indicate the same parts throughout the several views. The machine is mounted on a suitable platform 1 and can be driven by any suitable motive power, and power is applied by means of `18 and 19 on wheel 7.

Figs. 12 and 13 illustrate the auto-` a wheel 2, mounted on a shaft 3. Wire is supplied from spools and is first run through rollers A and B for straightening it. A hollow shaft 4 receives the wire. This shaft is driven by beveled cog 5, mounted on shaft 3, and beveled pinion 6, mounted on shaft 4. Wheel 7 constitutes a part of the means for operating the wire-twister 8, the folder 9, and the cutter 10. The twister 8 is mounted on .shaft 4 and consists of the body part or tube ,8, the fingers 11, pivoted thereon, the clamp 12, andthe pivoted arm 13. are pivoted on the twister 8 and have a suit- The fingers 11 able bearing 14, which causes the arms to open and close as the twister is moved back and forth. The bearing 14 for fingers 11 is mounted rigidly on the shaft 4 and revolves as the shaft revolves. This bearing may consist of two parts bolted together or it may be cast in one piece. Antifriction-rollers D may be putin the bearing to facilitate the passage of fingers 11. The otherend of the twister has an annular iange 15, which revolves in a groove in ,clamps 12. An arm 13 is pivoted in clamps 12 and in' a suitable bearing 1G, mounted on platform 1. Aroller 17 is mounted on arm 13 and is adapted to engage dogs When the roller 17 engages dog 18, the twister is forced forward to engage the wire for twisting same, and when wheel 7v is turned far enough for roller 17 to engage dog 19 the twister is forced back to its normal position.

VWheel 7 is driven by pinion 20. On the shaft with wheel 7 is mounted a pinion 21, which meshes with pinion 22. By the means thus described Wheel 23 is driven. A portion of pinion 21 is blank, as shown in Fig. 5. This is for the purpose of allowing the wire to stop long enough to be twisted to hold the loop in the wire. A portion of pinion 21 being blank wheel 23is allowed to stop for a short interval.

The loop-forming mechanism consists of a lug 24, mounted on the wire-carrying device, a guide 25, a bent lrod 9, and the wire-twister already described. -Rod 9 is journaled in a suitable bearing 26 and has a pinion 27, mounted on the outer end. This pinion meshes with rack 28, which is connected to a bar 29, bearing a roller 30. Bar 29 is mounted on and slides on a bar 31. Bar 31 is attached toA two uprights 32, which are bent over to hold bar 29 in place. Roller 30 is adapted to engage a dog 33. This forces the rack 28 forward and revolves pinion 7, and consequently rod 0, and so bends the wire into a loop. Guide 25 prevents rod 2G from bending the wire below fingers 11. A spiral spring 34 engages rack 2S and draws the rack back and so replaces the rod 26.

The wire-cutting mechanism is shown in Figs. 1,4, 6, 7, and 8. An upright 10 is mounted on the platform 1. The cutting device is mounted on this upright and consists of a cutter-bar 35 and a bar 36 for holding the wire on shoulder 37 while being eut. These two bars are connected together by a spiral spring 3S, and these three pieces are inclosed in a case 3f), mounted on upright 10. Springs 3S and 50 show the cutter and its mechanism in place. A bellcrank lever 40 is pivoted to bar 35 and on upright 10. A rod 41 is pivotally joined to lever 40 and the other end is inserted in a connecting-block 42, which may be of any convenient shape. A rod 43 is inserted in this block and attached to a lever 44. Lever 44 is pivoted on the platform at'45. A rod 4G, bearing a roller 47, is mounted loosely in a bearing 48 and engages lever 44. A dog 49 is secured to wheel 7 and is adapted to engage roller 47. This dog throws lever 44out and consequently the cutting-bar 35 down. A spiral spring 50 draws the several parts back in place.

The ties are discharged by means of the mechanism illustrated in Figs. 1, 2, 9, 13, and 14. A bar 5l, bearing lug 24, is mounted in a track composed of bars 52 and 53, provided with iianges which prevent bar 51 from falling out at the sides. On this bar is pivoted a bar 54 for throwing the wire off of lug 24. 'This bar has a loop in which lug 24 is held, and the bar is pivoted at 55 and curved at 5G. Curve 5G engages a curved arm 57, mounted adjacent to track-bars 52 and 53. This meehanism throws bar 54 to a position as illustrated by dotted lilies in Fig. 9, and so throws the wire into trough 5S. A spring 59 throws bar 54 back into its normal position. Spring 59 is wound on a curved bar which serves as a guide. Bar 51 is driven back and forth by wheel 23 and the framework illustrated in Fig. 14. The bars GO and 61 are pivoted on a bolt 62, attached rigidly in bar 51. Two other bars 63 and G4 complete a quadrilateral frame Il, with bars GO and 61 pivotally attached at each corner. The bars 63 and 64 extend beyond the corner and form a smaller quadrilateral G, with bars 65 and 90 also pivotally joined together. These frames are driven back and forth by rod GG. Wheel 23 Serves as a drive-wheel for the mechanism thus described. A cuff 67 is pivoted on platform 1. A bar GS is attached rigidly to the lower end of cuff G7. Bar 68 is pivotally connected to bar G6 at its lower end and the upper end is pivoted by means of a cuff G9 to a pitman-rod 70. During a revolution of wheel 23 the frame H carries bar 51 out to its limit and the wire is thrown into the trough 58. The parts marked 78, 71, 80, 8l, and S2 are braces. A block 83, provided with a slot, is mounted on a suitable support S4. This block guides the frame G back and forth. The pivot-bolt S5 extends through the slot in block 83 and is held in the slot in any suitable way, as by a nut and washer.

An automatic counting device is attached to platform 1 on the under side. A rotating disk 73 is provided with teeth projecting downward and arranged around near the edge of the disk, one of these teeth being longer than the other. A pawl and a ratchet-wheel are mounted on a hanger 74, adjacent to disk 73. The ratchet-wheel 76 has a lug 76',whieh engages the teeth of disk 73. A finger 75, attached to cuff 69, registers with and drives the ratchet-wheel 7G. A spring S6 holds finger securely against ratchet-wheel 7 G. There are ten teeth on the ratchet-wheel and there are twenty-tive teeth on the disk 73. Every revolution of wheel 23 causes one tie to be discharged into the trough and causes finger 75 to move the ratchet one tooth. One revolution of the ratchet-wheel indicates that ten ties have been discharged, and the lu g on the ratchet-wheel turns disk 73 one tooth, so that a complete rotation of disk 73 indicates that two hundred and fifty ties have been discharged or delivered. A bell 77 is arranged so that a pivoted spring-pressed lever will be struck by the long tooth on disk 7 3, thereby ringing the bell whenever' a complete rotation is made. (See Fig. 12.)

The operation will be readily understood. The wire is.reeeived through rollers A and B into the hollow shaft 4. Then the wire reaches the cutter 10, it is cut ofi to begin a new tie. When cut, lthe folder 9 turns the wire around lug 24 back over guide 25.

lVheel 7 at that instant throws the twister.

forward, and the fingers 11 grasp the wire thus bent back and also the main wire and twists the bent portion around the main wire. While'this is being done pinion 22 has reached the blank place in pinion 21. Consequently the driving mechanism of the carrier has stopped. By the time the wire is twisted enough pinion 22 will again engage pinion 21and so start the carrier 51. lVhen the carrier has drawn the wire far enough, the wire is cut off. The tie is complete and is immediately thrown into the trough 58 by the tripping-bar 54.
