WILBER EMERY, OF WILMINGTON, DELAWARE, ASSIGNOR TO PITTSBURGH STEEL COMPANY, OF PITTSBURGH, PENNSYLVANIA, A CORPORATION OF PENNSYL- VANIA.

Application filed January 9, 1913.

To all wlw/m. it may Concern:

Be it known that I, VILBER EMERY, a citizen of the United States, and resident of l/Vilmington, in the county of New Castle and State of Delaware, have invented a new and useful Improvement in Bale-Tie Machines; and I do hereby declare the following to be a full, clear, and exact description thereof.

My invention relates to bale-tie machines, or machines of like character.

The object of my invention is to provide a simple machine of this character in which wires are cut to lengths, and the bending and twisting of the wire to form the loop is done in a rapid and eflicient manner, so as to turn out the bale-ties in large quantities at low cost.

T o these ends my invention comprises the novel features hereinafter set forth and claimed.

Referring to the drawings Figure 1 is a top plan view; Fig. 2 is a side elevation of the machine; Fig. 3 is a vertical section through the line 3 3 of Fig. 1; Fig. 4L is a horizontal sectional detail through 'the bending and twisting head; Fig. 5 is a detail of the cam which actuates the bending mechanism; Figs. 6 and 7 are details of the cutting off mechanism; Figs. 8, 9 and 1() are details of the bending mechanism; Fig. 11 is a detail of the clamping device; Figs. 12 and 13 are details of the jaws which assist in the bending operation; F ig. 14 is a vertical section on the line 11i- 14, Fig. 1; Figs. 15, 16 and 17 are details of the counting mechanism; Figs. 18 and 19 show the device for retaining the wire while it is being fedy forward and dropping it after it is cut olf, and Figs. 20, 21, 22 and 23 show the different positions of the wire during the twisting and bending operation. Y

In the drawings the numeral 1 designates a suitable bed supported by legs 2, 2a which are bolted to I-beams 3 and Ll.' The bed carries a suitable straightener a which is of common construction and does not need to be specifically described. The main shaft 8 is driven from suitable source of power by a belt engaging the pulley 8a, and gear mechanism driven by said shaft operates the wire feeding mechanism ZJ and the cut-off head c, all as shown and described in an application led by me March 4, 1912, Serial No.

681,587. rlhe cut-off head o, however, of the present application differs to some extent from that shown in said application. The cut-off head c is keyed on shaft 34 and said head has the annular slot c', the bottom of which is approximately the same diameter as the feed rolls in the feeding mechanism b. Across the front of head c in a slot a9 in said head is the lever c2 fulcrumed on pin c3. A spring c* inserted in a. recess in shaft 34 bears against the lever c2 and normally forces the same outwardly. The lever c2 carries the movable cutter c5 which is securely fixed in said lever, said lever having the projection c6. A fixed cutter c7 cooperates with the movable cutter c5, said movable cutter being actuated periodically by the pin 0S on the cam-wheel d which engages the projection c, and the wire is cut in slot c when the amount of wire for one bale-tie has been fed to the machine.

The spur gear e is keyed on the shaft S, and through gears fl, e and e2 operates the shaft es which is` supported in bearings on the uprights e* bolted to the I-beams 3 and fl. The uprights e4 carry the flat rod e5 and said rod carries the brackets e and e7. A plate e is inserted in the slot es of brackets e@ and e7 and said plate acts normally to close the slot 61 in the wire-guide e to retain the wire fed to said guide before said wire is cut. This wire-guide e is not continuous, but may be in sections so that {ingers cl2 studded on circular plates 613 carried by the shaft e3 may pass between the sections and force the wire out of the slot @10 each time said slot is opened by the movement of the plate e9. To provide for the movement of the plate e9 I employ the following mechanism: On one of the circular plates @13, the first one of the series, is the lug e:L4 which contacts at each revolution of the plate @13 with a friction roll @15 studded on the lever @16. The lever el is pivoted on e which is fastened in the cut-away forward portion of the rod e5. The friction roll @15 is held against plate @1,3 by spring els attached to rod e5. The other end of lever @1G is inserted in a transverse slot in the plate e9 and when the roll e is moved forward the plate e9 is moved backward. Pins 619 are fastened in the under side of plate e5 projecting through diagonal slots e2 in said plate e9 and as the lever ew pushes back the plate 69, the diagonal slots 620 cause the plate 6 to move diagonally backward and sidewise. This causes the plate 6 to open the slot 610 and this movement is timed at the precise instant that fingers 612 on plates cl3 press upon the wire to move it out of the guide 611.

A rod 621 passes through the brackets 6G and 67, and star-wheels 622 are keyed on said rod. One of these star-wheels is guided by two pins 623 on the plate 613. The first pin actuates one of the star-wheels 622 and through it the rod 621 with its series of star wheels 622 to discharge the wire after the same has been headed. The second pin 623 actuates the star-wheel, so that the series of star-wheels embrace between their points the descending cut length of wire carried down by fingers 612 on the circular plates 613. At the instant that the wire is so embraced the fingers 612 strike pins 640 fastened in the side of uprights 64 and as the fingers bend backward against the pull of springs 62f to clear said pins, the wire is left in the embrace of the star-wheels 622. To prevent the rod 621 with its star-wheels from spinning, I employ a simple form of locking device consisting of the spring actuated locking-pin 625 engaging in depressions of the hub of star-wheel 622.

On the rod 621 is the fixed bevel-gear 626 operating through bevel gear 62T and worm 628 the worm wheel 62 which is integral with the cam-wheel 630. rhe said worm-wheel and cam are loosely mounted on a pin 63l in the bracket 67. The cam 630 has a pin 632 resting against its periphery, said pin being secured in lever 633 and a spring 634 acts to hold the pin 6s2 'n contact with said cam. The lever 633 is keyed on the rod 635 which passes through brackets 6G and 67 and is supported thereby. The rod 635 carries fixed on it a series of arms 636. This mechanism constitutes the counting device and operates as follows: The cam 630 beingactuated by the revolution of rod 621 through gears 62, 627 and worm 62S and worm wheel 629 makes one revolution to one bundle of ties, say 250. The arms 63G are gradually carried outwardly by the action of cam 630 allowing the ties which have accumulated between them and the uprights 64 to drop down into the horns 637, which may be formed integral with the uprights 64. As soon as the count of ties for one bundle is complete the arms 63G are drawn back quickly by the action of spring 634 so that the passage of ties to horns 637 is blocked, and the operator has time to remove the bundle before the arms 636 again open.

I will now describe the twisting and bending mechanism.

On the shaft 8 is keyed the bevel gear g meshing with the bevel gear g which is keyed on the end of the bending and twisting head g2 which is supported in bracket g3 and carries the collar g4 with an annular groove g5. Pins g and gT on the levers g8 and g enter the groove of the collar g4 and said levers are keyed on opposite ends of pin g1" which has a bearing in bracket g3. The levers g3 and gg with the pin glo form substantially a yoke. The lever g8 carries the pin g and roller g which is adapted to roll in the groove g1 in the side of camwheel (l. A pin giL4 passes through the col lar g* and is fastened to same and said pin passes through an elongated slot 915 in the head g2, said slot permitting the pin with the collar g4 attached to move lengthwise on head g2, but said collar and said pin must rotate with said head. The pin g14 also passes through a hole in the slide g1 which slides in a groove in the side of the head g2. The slide gw carries on its forward end the bending member g pivoted on the pin g18 fixed in the slide gw. The bending member g" has the irregular or cam slot gw. 4The head g2 is tapered at its front end and partly cut away. Under the bending member g is inserted the fixed plate g2 which carries the pin 921 extending through the groove g1. The plate g20 has the jaws g22 and g23 and inclined planes ggf. The plate g carries at its front end the pin g25.

The action on the wire of the above described mechanism is shown in Figs. 20 to 23. The cut length of wire being carried down by the mechanism previously described is so positioned that the end rests on the tapered end of head g2 and on the support or jaw 922 of plate ggo as shown in Fig. 20. The cam-slot Q13 has actuated collar g* and moved the same forward carrying with it the slide g1 and bending member g, and this operation has through the movement of slot g19 on the pin g21 thrownthev pin g25 outward from between the liaws 922 and 923 and upwardly to the position shown in Fig. 20, so that the revolution of the head g2 brings the pin gf above the wire which is resting on the tapered end of head g2 and jaw g. When the collar g4 is drawn back by the action of the cam-groove 5713 the pin 925 acting on the wire draws the wire down between the jaws g22 and 923 and the further revolution of the head brings the wire into the position shown in Fig. 21. In this way the bent end is thrown up to joinl the longer section of the wire between the clamps L, h. The clamps are timed to close at this point in the operation, thereby clamping the wires so that the continued revolution of the head g2 twists the head of the bale-tie in the manner shown in Fig. 22. When the head of the tie is completed 'the cam-slot g1g is so adapted that the collar g4 may be drawn backward by the spring g2 bringing the pin IOC lli)

g between the inclined planes g2* and so throwing downward the completed tie-head as shown in Fig. '23.

'.lhe clamps It, it are actuated in the -fcllowing manner: Clamp la is iiXed in bracket i112 adjustably by means o` the set screw it. The clamp it is movable in the bracket it* being attached to lever h5 pivoted upon pin 71. and held against cam las oi cam wheel Z by spring its). Clamps it and lt are equipped with iins IL10 and it to guide the downward moving wire and clamp It is beveled in front to guide the bent end of wire as'it moves backward. The bent end of the wire having been twisted in this manner the wire is discharged from sta1'-\'vheels @22 and dropped down on the bent arms es from which it is dropped into horns esT to form bundles oi' any desired number.
