JOI-IN A. SCHARF, F RICHWOOD; OHO.

BALE-TIE MACHINE.

To all whom 'it Amay concern:

Be it known that T, Jer-IN A.. SCHARF; a citizen of the United States; and a resident of Richwood7 in the county of Union and State of Ohio, have invented a new and lmproved Bale-Tie Machine, of which the following is a full; clear, and exact description.

This invention relates to bale-tie making machines of a type in which the wire is automatically drawn out; a loop twisted therein and tightly stretched and removed from the machine.

An object of this invention is to form a simple and effective machine, which will perform the various operations of drawing out, bending7 twisting, stretching, cutting and removing the bale-ties from the inachine; with a small amount of powerl and with the least attention from the operator.

Another object is to form a plurality of bale-ties simultaneously.

Tn previous automatic machines the heavy loop forming mechanism has been made movabl ,g a further object therefore, of this invention. is to provide a machine on which only the light wire drawing mechanism is to be carried.

These, and other objects, will be more fully described hereinafter', and particularly pointed out in the claims.

drawing carriage about to remove the loop from the twister; Fig. 11 is a vertical cross section on the line 11-11 in Fig. 3; Fig.'12 is a horizontal section on the line 12-12 in Fig. 5; Fig. 12a is a vieu7 similar to Fig. 12 showing the clutch in the act of being thrown into engagement; Fig. 12b is a detail section of the same showing the clutch in engagement; Fig. 13 is a side view of the twister driving mechanism showing the clutch about to be thrown out; Fig. lt is a top view of the twister driving gear; showing a portion of said gear stripped of its teeth; and Fig. is a plan view of a wire clamp mechanism with the top removed; on the line 15H15 in Fig. 1.

Referring more particularly to the separate parts of the device; 1 is a frame composed of a base Q, supporting uprights 3 and a top a; the whole being suitably braced by struts 5. The top t is composed of two longitudinally extending angle irons the flanges 6 of which extend inwardly toward each other, and engaging these flanges are franges 7 on the wire drawing carriage 8. This carriage is adapted to slide back and forth on the top 4, utilizing the flanges G as ways. Pivotally secured in any suitable manner to the carriage 8 is a shaft 9, and pivoted to this shaft 9 and extending toward the front of the carriage are a pair of arms 10 which have; at the ends thereof; upwardly extending prongs 11. Secured to said arms 10 and pivoted to the shaft 9 and extending in the opposite direction is an arm l2. This arm is pivotably secured in any suitable manner to a box link 13 on an endless chain 14, this chain 14 being supported by sprocket wheels 15 and 1G. The sprocket wheel l5 is driven by shaft 161, which in turn is driven by any suitable motor; such as beltdriven pulley 17. The arm 12 may be'made integral with the arms lO and preferably extends at an angle to said arms, forming therewith a structure similar to a bell-crank lever. Suitably supported on the wire drawing carriage 8 is a trip support 18; which has supported thereon a tripping roller 19; which is adapted to engage various trips on the frame. which will be more fully described hereinafter. The sprocket wheel 16 drives a shaft 19, which in turn drives a sprocket wheel Q0; which drives an endless chain Q1. This chain on its upper side passes under a suitable guide roller 22, and over another sprocket wheel '23. This sprocket wheel 23 is fastened to a shaft 2st, which is suitably supported in the frame -l-. This sprocket wheel has formed integral with it a clutch 25, and this clutch 25 is adapted to drive the twisting mechanism, which will be more fully described hereinafter.

At the opposite end of the frame from that on wiich the carriage is located, as shown in Figs. l and 2, the wires are adapted to be fed to the machine from any suitable means, such as reels, (not shown) over guides QG. These guides 2G may be of any suitable form, but are preferably oppositely disposed rollers suitably supported on the frame l, the wires then extending from the guides to a pair of clamping devices. These clamping devices consist of frames 2T suitably supported on the frame fl, and clamping blocks QS, (see Fig. l5). 1

Co-acting with said frames are cam levers Q9, adapted to actuate the clamping blocks QS to clamp the wires between the blocks and the frames. These cam levers 29 are operated by a pair of links 30 suitably secured to the top of a lever 3l, which is secured to a shaft pivotally mounted in the frame i, (see Fig. The lower end 33 of the lever Si is connected to a link which extends to the rear of the frame, and is connected to a trip 35, (see F ig. 3) pivotally supported in any suitable manner on the frame et. This trip 35 is supported in such a position that it is adapted to be engaged by the trip "i8 on the carriage 8 when said carriage has reached its extreme travel to the right, away from the twisting mechanism.

From the wire clamps 2T the wires pass through the wire tension devices 3G, which are adapted to hold the wire under tension. rIhese wire tension devices 36 are composed of a bar 3T which is fastened in any suitable manner to the frame el, and has at each end thereof plates 38 movably connected to the bar by means of pins 39. These pins 39 yieldingly hold the plates 38 against the bar by means of the springs at). rlhe wires pass between the plates 38 and the bar 37 and are yieldinglj,- held by the springs i0. From the wire tension device the wires pass to a pair of clamps del which are adapted to clamp the wires when properly7 operated. These wire clamps el consist of bed plates '-12 and clamp rods 4:3 co-acting with said bed plates to grip the wire between them.

The rods #f3 extend substantiallyT vertically downward to engage a pair of arms Jet of a bell crank lever, which arms are secured on a shaft 45, rotatably secured in any well known manner on the frame et. Extending at an angle to the short arms ed and secured to the shaft 45, is another arm il@ of said bell crank lever. This arm a6 is engaged in any suitable manner by the connecting link 47, which in turn engages an arm of another bell crank lever. Vthis latter bell crank lever is suitably pivoted to the frame 4 at Ll-). lever is engaged by a long connecting link 5l. The long arm 4S of the last mentioned bellcrank lever also forms a trip whose operation is to be more fully described hereinafter. The connecting link 5l extends along the under side of the frame 4, and is suitably connected to an arm 52, which is 1iivoted to the frame at This arm 52 is adapted to be thrown over beyond its pivot 53 by means of a trip 54. rthis trip 54 is held in the position shown in Fig. 3 by means of a spring This trip is adapted to be operated by the tripper 18 on the carriage 8 in order to operate the clamping device to clamp the wire. rlhis operation will be more fully described hereinafter.

The ends of the wires having been passed through the wire clamps Ll-l extend just beyond the twisting hooks 56, around which they are adapted to be bent by the bending fingers 57. rlhese bending` fingers 5T curve inwardly and downwardly and are guided in slots 58 in the frames 59, which are fastened in any suitable manner to the top of the frame et. Integral with the bending lingers 57 and pivotally supported by the frame l in any suitable manner are the vertical shafts 59a. These shafts 59 have on the lower extremities gears G0 and 6l, which are fastened thereto and adapted to operate the same. he gear Gl meshes with an idle gear 62, which is supported in any suitable manner, as by means of a stub shaft G3 on the frame. rl`he gear G2 and gear GO mesh with a double sector gear (Si. rhis double sector gear is pivoted to the frame in any suitable manner, as by a stub shaft G5, and is adapted to operate the gears G0 and 6l to turn the shafts 59, and thus operate the bending fingers 57 to bend the wire about the twisters The ends of the wires being bent about the twisters 5G pass between the clamping plates on the wire clamps 4l, which are adapted to be clamped down on the ends to hold the ends and the main body of the wire from moving during the twisting operation.

The sector gear 64 is operated by a connecting link 65a, which extends along the frame l to one arm G6 of a bell-crank lever pivotally secured at 67 to the frame et. This bell-crank lever is adapted to be drawn over beyond its pivotal center 67 by means of a trip 68, which is also pivoted at 67. This trip G8 is held in the position shown in F ig. 3 by a spring` 69, and is adapted to be operated by the trip 18 on the carriage S in a manner to be described more fully hereinafter. Another arm 70 of thebellcrank lever of which 6G forms a part, is

A long arm 4S of this bell crank .Y

connected in any suitable manner, as byV means of a connecting link 71, to a trip 72 and adapted to be operated thereby. This trip 72 is pivoted to the frame 4 at 3, and is adapted to be operated by the tripper 1S on the carriage S so that it will throw the arms 66 and 70 of the bell-crank lever' over into their original position and draw back the link and thus return the sector gear 64 to its original position. Then the wires in their bentl position form a loop around the twisters 56 and are clamped by the clamps 41, they are then adapted to be twisted. The twisting` hooks 56 are integral with shafts 74, which are suitably supported in the frames 59. These shafts 74 are adapted to be rotated by the beveled pinions 75, which pinions mesh with pinions 76 fastened on the ends of a shaft 77. This shaft- 7 7 is adapted to be rotated by a pinion 7 S, which is also fastened to the shaft 77. The pinion 7S meshes with a gear 79, which is loosely mounted on the shaft 24. This gear 79 has teeth on only part of its circumference, the remainder of the circumference being bare, as shown in Fig. 14. Corresponding to the bare portion S0 of the gear 79 is a flange 81, which extends outwardly from the side of the gear and toward the sprocket wheel 23 and the clutch 25. This flange S1 has a slot 82 therein, the ends of which are extended somewhat beyond the top of the main flange and curved up to the edge of the slot. Fastened to the shaft 77 alongside of the pinion 7 8 is a cam shoe 83. (See Figs. 12 and 13a.) This cam shoe is adapted to rotate between the gear 79 and the clutch 25, during the interval when the flange 81 is on the opposite side of the shaft 24. The number of teeth on the gear 79 and on the pinion 78, are so designed that the pinion 7S will revolve several times, preferably three, while the gear 79 revolves once; and also so that the cam shoe 83 will co-act with the flange 81 and slot 82.

On the hub of the gear 79, as seen in Figs. 12, 12a, 12b and 13, and secured by means of the pins S4 is the clutch S5. This clutch 85 has a U shaped frame,with slotted extending arms 86. These slots in the arms S6 slidingly engage pivot pins 84. The outer surface of the U shaped frame has serrations or teeth S7 formed thereon, which are adapted to engage the internal serrations or teeth SS on the clutch 25. The clutch 85 is pressed away from the hub by means of a spring 88a, which operates on the under side of the U shaped frame. Extending at right angles from the clutch is a pin 89, which passes through a slot 90 in the gear 79, and has a cam head 91 on the outer extremity thereof. This pin 89 assists in holding the clutch 85 to the gear 79, and also is adapted to throw the clutchinto engagement with theteeth 88 on the clutch 25. Extending outwardly from the top of the U shaped frame to the clutch 85 is a lug 92. This lug 92 is adapted to extend through the slot S2, and is also adapted to co-act with the cam shoe 83 on the shaft 77. The pin 89 which throws the clutch 85 into engagement with the clutch 25 is adapted to co-act by means of its outer surface 91 with a cam surface 93 on the lever 94. This lever 94 is suitably pivoted to the frame 59, as at 95 shown in Fig. 7. At the lower extremity of this lever 94 is connected a link 96, which extends along the frame 4 to a trip 97. This trip 97 is pivotally secured in any suitable manner to the frame 4, as at 98, and is held in the position as shown in F ig. 3 by means of a spring 99. This trip is adapted to coperate with the trip 1S on the carriage 8 in a manner to be described hereinafter.

J ust beyond the twisting hooks 56 are wire cutters 100. These wire cutters consist in stationary frames 101, to which are suitably secured stationary knives 102. These knives 102 are adapted to cooperate with movable knives 103, which are slidingly supported by the frames 59, in any suitable manner. These movable knives 103 are adapted to be operated by bell-crank levers 104, which are pivotally secured to the fra-me 59 as at 105. @ne arm 106 of the bell-crank levers 104 engages slots in the knives 103, and is adapted to reciprocate said knives. The other ends of the bellcrank levers 104 have arms 107 which are engaged by links 10S extending forward of the frame 4 to a pair of arms-109, fastened to a shaft 110, which is pivotally supported in any suitable Amanner on the frame 4. EL tending downwardly, and fixed to t-he shaft 110 is an arm 111, which is connected to a link 112. This link 112 extends to the other end of the frame 4 where it engages an arm 113 on a bell-crank lever 114. This bell-crank lever 114 is pivotally secured to the frame as at 115 in any suitable manner, and has another arm 116 extending at an angle to the arm 113. This arm 116 is adapted to coperate with the box link 13 on the chain 14 to which the arm 12 on the carriage 8 is pivoted. This box link 13 is adapted to operate the lever 114, and through the link 112 operate t-he wire cutters 100. On the sides of the frame 4, suitably supported thereon are the lugs 118, which form a rest for the wires after they are drawn out by the' wire drawing carriage 8.

In following the operation of-the device wc will assume the carriage S starting from its extreme right hand position with the arin 12 traveling on the upper side of the chain 14 in the direction of the arrows shown in Fig. 3. W e will also assume that the wires have been passed through the guides 26, the clamps 27, the tensioners 36 the arrows in Fig. 3.

and the clamps 4:1, and the ends extended alongside of the twister hooks 55, ready for the lirst operation of bending. rlChe chain 14: draws the carriage 8 in the direction of The tripper roller 19 first comes in contact with the trip 68. This throws the trip 68 against the action of the spring G9 and forces the bell-crank lever GG over beyond its pivot G7 and draws on the connecting link 65a, which in turn revolves the gear sector G11 through a part of ay revolution. This gear sector G4 operates the pinions G1 and 60 to revolve the shafts 59, and these turn the bending fingers 57 to the position shown in Fig. 8. This operation bends the ends of the wire about the twisting hooks 5G, forming a loop, the ends of which are between the clamping members of the clamps 11. The trip on the carriage 18 next cornes in contact with the trip 54, and throws this trip against the action of the spring 55 so that the link 51 is drawn toward the right. This link 51 turns the arm 50 of the bell crank lever pivoted at 419, which in turn throws, through the connecting link 47, the lever arm 16, which operates t-he shaft 45, drawing clown the arms 41s, which in turn operate the clamping members The clamping members 43 coact with the bed 42 to clamp the wires and the ends thereof together, holding the loop fast to prevent its pulling out during the twisting' operation. The tripper roller 19 next comes in contactwith the trip 72. By throwing this trip 72 it draws on the connecting links 71 and pulls the bell-crank lever G5 back into its original position, and by means of the connecting link 65, and the sector gear Get, revolves the shafts 59a so 4that the bending fingers 57 are returned to their original position, as shown in Fig. 9. On further motion of the carriage the tripper roller 19 comes in contact with the trip 97 and throws the arm 97a, over into a position beyond its pivoted pin. This arm 97a draws the link 96 which throws the lever 9st.

rl`he cam surface 93 on the lever 9erv cooperates `with the cani end 91 of the pin 89 to throw the clutch 85 over into the position y shown in Fig. 12a. This brings the clutch 85 into engagement with the clutch teeth 88 on the clutch 25 so that the gear 79 revolves with the shaft 211, and thus with the sprocket wheel 23. .Vhen the gear 79 is revolved sutliciently for the 'pin 89 to come out of contact with the cam surface 93 the spring l 88 forces the clutch back into the position shown in Fig. 12b so that it is still in engagement with. the clutch teeth 88' and the lug 92 extends through the slot 82 in the flange 81 on the gear 79. The gear 79 now revolves through one revolution, at the same time rotating the pinion 78 through a number of revolutions, preferably three. This in turn drives the beveled gears 7G, which mesh with the gears and turn the twisting shafts 74 through a number of revolutions. The hooks 56 are thus revolved so that they twist the loops of the wire, as shown in Fig. 10. While the gear 79 iS revolving, the cam shoe 83 is also revolving with the shaft 7 7 and is in such a position that it passes between the gears 79 and clutch 25. At the end of the revolution of the gear 79 the cam shoe 83 comes into coaction with the stripped surface 8O and forces the lug 92 back through the slot 82 into the position shown in Fig. 12. The gear 79 is thus thrown out of connection with the sprocket 23 and ceases to revolve. Thus the twisting motion of the hooks 5G also stops. The wire drawing carriage 8 now travels to its extreme left hand position, as shown in Fig. 1, where the tripping roller 19 comes in contact with the trip arm 48 on the bell-crank lever having the short arm 50, and throws it over in such position that it operates the. bell-crank lever arm 46 to throw up the clamping members 13 and rel-ease the wires from beneath clamping members l"Vhen the chain 14 draws the box link 13 down under the sprocket wheel 15 the arm 12 is tilted down. This operation serves to elevate t-he arms 10 so that the prongs 11 engage the loops of the wires and remove said loops from the twisting hooks 5G, the clamps having been released as previously stated. The carriage 8 now travels to the right, drawing the wires with it until it reaches its right hand position, as shown in Fig. 3, when the trip roller 19 comes in contact with the trip 35 drawing it into such a position that it draws on the link 34. This link 3lthrows the arm of the lever on the shaft 32, which in turn operates the links 30 to throw the cam levers 29. These cam levers 29 force the clamping blocks 28 outwardly, so that they clamp the wires between their surface and the surfaces of the frames 27. The wires are thus held rmly during the next operation, which is the stretching operation. The carriage 8 travels a short distance after coming in contact with the trip 35, and still holds the clamps in operation by reason of the length of the trip 35, until the arm 12 has traveled beyond the sprocket 15 and up to the top of the same. This operation serves to draw out or stretch the wires; and at the same time when the box link 13 comes to the top of the sprocket wheel 15 the arm 12 is elevated and the arms 10 depressed, so that the prongs 11 are removed from the loops of the wires. Meantime the box link 13 has come in contact with the arm 11G on the bell-crank lever 1111 pivoted at 115 and has thrown the. same over into such posit-ion that the other arm 113 draws on the link 112. This link 112 revolves the shaft 110 so that it turns the levers 100 which draw on the links 108, which links operate the wire cutters 103, and the wires are thus severed at the end of the stretching operation. The travel of the boX link 13 from the end to the upper side of the sprocket wheel 15, has elevated the arm 12 and depressed the arms 10, so that the prongs 11 are removed from the loops of the wires, the wires being supported by the ings 118 on the sides of the frames A complete bale tie thus formed drops into a suitable receptacle below the machine. The wire drawing carriage now travels forward in t ie direction of trie arrows shown in Fig. 3, to perform another complete operation.
