GEORGE BULL, OF MONESSEN, PENNSYLVANIA, ASSIG-NOR TQ STEEL COMPANY, OF PITTSBURGH, PENNSYLVANIA, A CORPORATION OF PENNSYL.

VANIA.

citizen of the United States, and resident of Monessen, in the county of l i estmoreland and Fatate of'Pennsylvania, have invented a newand 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. The object of my invention is to provide a simple and efficient machine of this character in which a single strand of wire may be fed continuously to a cutter to be out into predetermined lengths, and then quickly bent and twisted to form a single loop tie, the operations of looping and twisting b ing done with-great accuracy and rapidity insuring the continuous operation of the machine without interruptions due to failure of the parts .to operate in unison, and so produce defective ties.

To these ends my invention comprises the novel features hereinafter set forth and claimed,

In the accompanying drawings, Figure l is a plan view of my improved machine partly broken away. Fig. 2 is a side elevation partly'broken away; Fig. 3 is an enlarged sectional view of thebending and twisting mechanism; Figs. 4, 5 and 6 are details oi? the bending and twisting mechanisms showing the steps of the operation;

Fig. 7 is an enlarged section on the linev 7-7, Fig. 1; Fig. 8 is an enlarged section on the line 88, Fig. 1; Fig. 9 is a similar view to Fig. 8 showing the parts in a different position; Fig. 10 is a view similar to Fig. 8 showing the parts in a still different position; and Fig. "11 is an enlarged section on the line 1111, Fig.1; and Fig. 12 is a face view of the cam for operating the clamping jaws and the wire cutting device.

in the drawings, the numeral 2 designates a suitable stand or frame on which the machine is mounted. The shaft 3 is the main power-shaft mounted in suitable bearings 3*, said shaft having the tight and loose pulleys a and 5. Any suitable power may,

of course be employed to drive the machine."

At the outer end of the shaft 3 is the double gear 6 which is arranged to be slipped on a feather key and is retained in position by the washer 7. Different BALE-TEE nacnritn.

Application filed July 17, 1920. Serial No. 396,970.-

sized gears 6 may be employed in making of different lengths of bale-ties. The gear 6 transmits motion through the intermediate gear 8 and the gear-wheel 9. The intermeciate gear 8 revolves on the pin 10 which is adapted to be moved in the segmental slot 11, for adjustment of said gear. gear 9 is mounted on the shaft 12 of the wire-feeding mechanism.

The standard 13 forms a bearing for the shaft 14. which receives-motion from the shaft 12 I through. the gears 15 and 16. The shafts 12 and 14 carry the feed-rolls 17 and 18 which operate continuously into a suitable guide 19. The wire may be fed, however, by any suitable mechanism and as the feeding forms no part ofniy invention, it will not be necessary to refer to the same in further detail.

The double-gear'ti meshes with the gearwheel 20 and said gear-wheel 20'meshes in turn with the gear-wheel 21. In this manner, motion is transmitted to the cutterhead shaft 22 which is supported in the standard 23 of the bed, and said shaft carries at its forward end the cutter-head 24:. This cutter-head 2 1- has a slot 25 out in its periphery, and the smaller diameter of said cutter-head is the same as that of thefeedrolls 17 and 18, said cutter head being so geared as. to make the same, or practically the same, number a of revolutions as said feed-rolls.

A fixed cutter 26 is inserted in the cutterhead, and the coacting cutter 27 is fixed The in the block 28, (see Fig. 3,) which is pivotally mounted on the pin 29. The spring seated in the cutter-head and bearing against the block 28 acts to hold the cutter 27 normally out oi engagement with the cutter 26. The block 28 has the lug 31 pro-l jecting beyond the rim of the cutter-head, and, through the mechanism acting on said lug to be hereafter explained, the cutter 27 is moved forward to coact with the cutported in the bearing; 40. On the opposite end of the shaft 89 is the cam 41 carrying the lug lrlountcdin suiteble bearings is the shaft 14. ,Securedto said shaft 14 ere thesrrns liinnd loosely mounted in .the outer ends of said erinsis the rocker strei ht" portion 53 of the can]v 11, and the curved portion 55% for the hereinb fore set forth. 1 v

The wire 55 which is feo into the lie-chine by the feed-rolls 17 end 18 is passed through the guide 19 under the cutter-heed 28 and into the holder 56; This holder is provided withthe slot 57 to receive the removable member 58 h ving the groove 59 i'ornied purpose more fully therein to receive the wire 55. The holder is slotted transversely at intervals as at 60 to permit-of the entrance into said slots of the fingers l9. 1

To close the groove59 end retain the wire therein 'l provide the, movable cover-pieces 61' which are arranged between the cut-away portion 60 on the holder 56, and said coverpieces are mounted on the hanger-arms 62 which eresecnred' intervals to the rockershaft o lby means of the bolts 65' Monnted on the rocl er-shatt Giiiis the split-block66 secured in place by the bolt 67, (see 11). This block 66 carries the finger 68. A spring 69 is secured at one end to a bracket 70 on the frame, the opposite endot said spring being connected to the projection 71km the block 66. This spring 69 acts to normally hold the finger 68 in the position indicated in dotted lines.

Mounted on the rockersheft 4L6 is the c split-block 72which carries the trip-finger 7 which is adapted to engage the finger 68.

"When the, trip-finger 73 is in engagement with the linger 68; and said trip-finger 73 is ivenced by the action the com 41 engagthe roller 52, the finger 68 will be moved into the position indicated in full lines Fig.

' 11, whereupon the shaft 6 1- will berocked end the hangererins 62 moved outwardly so as to withdraw the cover-pieces to permit the wire to be withdrawn by the fingers 19 the holder 56, all as more fully hereinafter set forth.

I Between the fremepieces 74: is formed 7 the guide 75 WlllCl'l is in ellnement with the groove 59 of the wire-holder, and the wire is held by the lingers 19 in seid guide during the twisting operetionpaswill more fully hereinafter appear.

' Referring to Fig. 8 the bevel-gear 32' on 2 the shaft 3 1neshes with the bevel-gear 7'7.

which is'keyed on the endofthe bending and twisting-head {78 which issupported in thebracket 79, and carries the coller 80 with an annular-groove 81 formed therein; ins 82 on the levers 84:, (only one or" the levers being shown) enter the groove-o1v the 78, said slot permitting the pin with the,

collar 80 attached to move lengthwise on the head '78, but said collerand seid pin inust. rotate with said head.

passes through a'hole in the slide 98, which slides in a groove inthe side of the heed 7 8. The slide 93 carries on its forward end the bending-member 95 pivoted on'the pin 96 fixed in the slide 93; Thebending-member b '1 7 90 has the lrregular or, cam-slot 97. Thehead 78 1s tapered at its front'end and part y cut away. Under the bending member is inserted the fixed plate 99 which cerries the pm 100 extending through the groove 97, The plate 99 has the ews 101. and 102 The pin 91 also and inclined planes 104k. The plate 95 oerries at its front end the pin 105. The above described bending and twisting mechani in forms no part of my present invention but is the twisting and bending mechanism illnse j trated described in e patentto VVilber EIHGIY'NO. 1,163,902, Dec. 1 1, 1915.

A guard106 is providedto keep the wire 1n position on the'tapered end of the head 78 and jaw 102. I V

V Pivoted on the frame at 10'? is the arm 108 provided with thezinthfriction rollers 109 and 110. The roller 109 is adapted to engegethe projecting portion 31 of the lever 28, a-nd the roller 110 is adapted to be engagedby the cam 111 in the gear whe -e131. The operation of parts is so timed that upon each rotation of the gear wheel. the cznn 111 will act through the lever l08'to operate the cutter. V

Mounted on thepivot 1.12 are the clamp ing levers 113 and 114 carrying the clamping jaws'115. The clamping lover 118 has the extension member 116 provided with the lug 117. Links 118 and 119 connect the lug 11. with the lug 120 on the clamping lever 11%. The pivotal pin 121 connecting the links 118 and 119 is mounted on afblock' 122 moving in the guide 123. A spring 12% is connected to the block 122 and to a stationary support 125.

At the opposite end of the block 123 is the roller 126 whichi-s engaged by the upplace and the wire twisted 1 no es? through said lever to open and close the 1 clamplng laws 115.

In the operation of the machine, the wire 1s fed continuously b the feed rolls 1'? and 18 to the guide 19 and from the guide passes into the groove 59 in the holder 56. he soon as the wire has been fed to the length required, the cutting mechanism operated by the cam 111 acts on the lever 108 to oper- Z; liner). ately; the wire cut, th lug d2 on the cam 11 acts in contact with the lug 51 of one of the lingers d9, whereupon the shaft 46 is rocked so that the fingers 49 are brought up into a horizontal position, and at the same time the roller engages the straight face 53 of the cam 4:1 and the rock shaft 46 is moved over to the left, as indicated in Fig. 9, carrying with it the fingers to until the bifurcated ends of said fingers pass through the cutaway portions of the holder, as indicated in Fig. 9. As the straight face 53 of the cam tl continues to bear againstthe roller 52, the roller will be moved still. farther to the left and the rock shaft likewise, so that the trip fingers 73 is advanced bearing against the linger 68 and acting to rock the shaft 6 carrying the hanger arms 62 thereby moving the cover-pieces 61 out of the way as indicated in dotted lines 11. soon as the cover-pieces are withdrawn, the lug 12 of the cam ii. looses contact with the lug 51 and the fingers are free to move to the position indicated in 10 carrying the wire down into the guides 75. he inner end of the wire drops into the posi .1011 indicated in l and the bending operation then takes place by which the wire is bent into position indicated in 5. The gripping jaws 115 are then brought into position to grip the wirc by the action of the care 130 operating on the lever 11% which throws the clamping iaws into closed position, as indicated in Fig. 7. With the wire clamped in this manner, the twisting action takes as indicated in Fig. 6. Just as soon as the gripping jaws take hold of the wire, fingers 49 are freed from the wire, as the roller passes from the face to the receeding portion 54 of the cam 41. This brings the fingers back to normal position, as indicated in Fig. 8.
