BALETIE MACHINE.

SPECIFICATION forming part of netter-s Patentv No. 544,762, dated August 2o, 18e 5.

" Application led May 17, 1895.

To all whom) t may con/cern:

Be it known that I, GUSTAF JOHNSON, a citizen of the United States of America, residing at Denver, in the county of Arapahoe and State of Colorado, have invented certain n'ew and useful Improvements in Bale-Tie-Making Machines; and I do declare the following to be a full, clear, and exact description of the invention, such as lwill enable others skilled in the art to'which it appertains to make and use the same, reference being had to the accompanying drawings, and to the letters and figures of reference marked thereon, which form a part of thisspecification.

My invention embodies a machine for manufacturing bale-ties for baling hay, straw, and cotton.

The object of my invention is toprovide a machine for making various lengths of bale-ties with a loop at each end formed by turning the ends of the wire upon itself and then twisting the ends adjacent to the loop a number of times, thereby securely forming the loops on the ends ofthe wires. I attain these objects by the mechanism illustrated and described in the accompanying drawings and specification, in which- Figure l represents a plan view of a part of my bale-tie-making machine.

connected together by transverse timbersA' at suitable points and supportedl by legs A2. In Figs. 1 and 2l have dropped the frame considerably lower than in practice in order not to confuse the various parts by too many lines, and have placed blocks A8 upon the frame upon which the several parts requiring shaft and meshes with and drives a similar gear I. This latter gear is securedto the end of the shaft J, which shaft is journaled in boxes K centrally in the frame and extends the' entire length of the machine.. v

The gear Fis mutilated for a short space F' of its circumference, and on its outer side is a short concentric lateral projection K', registering with the mutilated portion. A block L is adapted to bear on said projection. The said block is secured to the end of shaft M, which is journaled. in a raised bearing M', which is arranged above the frame high enough to allow a pinion M2, which is secured to shaft M, adjacent to block L, to mesh'with the gear centrally over its axis. The shaft M extends through the bearing and has securedto its inner end a pinion-gear O and a feed-roller P. A second shaft Q is journaled in boxes R, which are supported by the two yoke-pieces S and S'. The boxes'R are divided at the center horizontally, and they'are adjustable by means of set-screws T. This shaft carries a pinion-gear U and a roller V. The pinion U meshes with and is driven by the pinion O, and the roller V is arranged directly over the roller P. These rollers are adapted to feed the bale-tie wire P into the machine.

Two auxiliary frames W and W', made preferably of cast-iron, rest on 'the blocks A3 of the main frame. These frames support boxes K and the main shaft J. One auxiliary frame IOO 4 and its contents.

XV is arranged adjacent to the transverse shaft and the other at the opposite end of the machine. The mechanism supported by one of these auxiliary frames is a duplicate of that of the other, except that one is righthanded and the other is left-handed, or oppo sitely arranged. Consequently a description of one will suffice for both. The frame W is adjustable longitudinally by means of a division made in the main shaft at the center of the machine, which is as follows: The main shaft is made in two lengths, which when the rear auxiliary frame WV is at the extreme end of the main frame leave space enough between` their inner ends to admit of sufficient longitudinal adjustment of the rear frame to make all the various lengths of bale-tie desired. To the end ot' the front length of the main shaft I rigidly secure a tubular piece X, which extends some distance over the adjoining end of the rear length. I secure a key Y inside ythe tube and out a keyway in the shaft fora short distance from the end large enough to enable the shaft to slide on it, thus feathering the rear length of shafting to the tube and consequently to the front length. The auxiliary frames may be secured to the main frames or blocks by any suitable means. Each auxiliary frame has two cross-yokes Z and 1. The yoke Z is provided with a long bearing 2, which stands centrally over the shaft. rIn this bearing is journaled a sleeve which forms an integral part of the guideblock 4. The sleeve projects beyond the front end of the bearing and to it is secured apinion 5. A rod which forms an integral part of the rack 6 (see Fig. 4) extends freely through 4the sleeve of the block 4 and is freely connected to one side of a yoke which forms a part of the lever 8. This lever is pivoted to two ears 9, which are cast on the auxiliary frames. The lever 8 surrounds the hub of the mutilated gear 10 freely below its pivoted support. Its lower end is adapted to engage the cam projection 11, formed on the side of the gear 10. j A spring 12 is connected to the other side of the yoke `formed on the top of the lever S, and is connected at its opposite end to an arm 13, which is secured to a part of the main frame. The gear 10 is mutilated one-half of its diameter, or is devoid of teeth. It meshes with the pinion 5 periodically, which it rotates together with the guide-block The rack 6 is seated in one side of the guide-block to reciprocate in it, and through the sleeve by means of the cam 11 on the mutilated gear engaging the lower end of the lever 8, causing it to swing on its pivots and push the rack and rod through the sleeve and in the block longitudinally of the axis of the bearing 2. As soon as the cam leaves the lever 8 the rack is returned to its normal position by the spring 12. A pinion 14 is pivoted in the guide-block to mesh with the rack. Iprovide this pinion with a hub 15, which I journal in a hub in the bottom of the guide-block and secure it by a pin 16. A flange 17 forms the top end of the pinion. This flange is larger than the diameter of the pinion through the teeth and extends a little over the teeth of the rack. The top of the flange forms a table-surface on which the tie-wire drops from the knife above. From one side of the flange of the pinion a finger 18 projects upward, which has at its base, even with the top of the flange, an inwardly-curved notch 19, formed by the junction with it of a second vfinger 20, which stands approximately at right angles to the finger 19. A cam 2l, which is a semicircular cam, and consequently operates through onehalf of each revolution of the main shaft, is secured to the main shaft and is adapted to engage the bottom of the guideblock 4 and hold it against rotative movement when the pinion 5 registers with the mutilated part of the gear 10. During this period the guide block is held by the cam 2l in a horizontal position, (see Fig. 4,) and the rack is reciprocated in the block by the cam on the gear 10 and lever 8. The reciprocation of the rack is timed to rotate the fingenpinion one-halfa revolution in the direction of the arrow. A projecting crotch-stud 22 is secured to the guide-block in a position which will enable the nger-pinion to revolve in a semicircle around it, a fragment of the linger beingshown in dotted lines in Fig. 4 in the position it assumes when rotated ou its axis by the outward stroke of the rack.

When the balc-wire drops from the knife 23, which is located above it, it is guided by the support 24 of the conduit 25 and the guidestrip 26v to fall in the crotch of the stud 22 and across the top of the pinion-Hange and in the path of the crotch between the fingers, which prevents its riding out-of the crotchstud and holds the end of the wire in axial alignment while the loop is being formed by the reciprocating of the rack and the partial rotation of the f1ngerpinion,which loops the wire, as shown in Fig. 4. The knife 23 is supported by the posts 27 and 28, which are secured to the main frame. An end elevation on alarger scale is shown in Fig. G. The knife is arranged in line with the friction feed-rollers P and'V, which feed the wire I into the machine from a skein or a suitable reel, neither of which is shown. A block 29 is secured to a cross-piece 30. Through this block a hole is made suitable to guide the wire between the knife and knife shearing-plate 67. This block also serves to guide the wire into the trough or conduit 25. The knife is pivoted to post 27 and arranged to move vertically in a guide-piece 32, vsecured to post 2S. A rod 33 connects it to a rock-arm 311-, which is secured to a shaft 35, journaled in a suitable bearing 36, attached to or forming a part ofthe auxiliary frame W. A second rock-arm 37 is secured to the opposite end of said shaft, which extends beyond the bearing. This second rock-arm is adapted to be engaged by a projectinglug 38, which is formed on one of the IOC IIO

spokes of the driving-gear and'thus moves the rock-arm in the direction of the arrow, which will pull the knife quickly down cutting, the wire. A spring 65, which is secured to the knifes free end and to support 66, attached to post 28, then raises it again to its normal posil tion. A knife shearing-plate 67 is secured to lation to the diameter of the driving-gear.

As several lengths of the tie are necessary to supply the trade I make the different lengths by changing the diameters of the feed-v rolls and gears, which thereby feeds the wire into the machine either fast or slow, and consequently in different lengths in relation to each revolution of the large driving-wheel F,

and by moving the rear auxiliary frame and' mechanism to the position necessary to make the respective lengths into ties. The instant a sufficient length of wire has fed into and through the conduit 25 to make a tie the rolls stop feeding. This stop is caused by the block L engaging the projecting portion of the gear F while the pinion M2 is in the mutilated portion of thegear, which locks thejrolls, the gears O andU, and shaft M against rotative motion in either direction. Consequently when the pinion enters the mutilated part of the driving-gear the pawl-block L at the same time engages the surface of the projection K', and thereby prevents the rolls from feeding in either direction until the pinion again engages the teeth of the gear, which does not occur until the knife has cnt the wire. It then resumes feeding and runs another length into the conduit while the loop is being made. After a loop is made, as shown in Fig. 4, it remains to be twisted, as shown in Fig. 7, which represents a full-size loop exactly as made by my machine. As before stated, the Wire is fed into the conduit 25 by the rolls and a predetermined length is cut off intermittently, the rolls stopping during the cutting operation. The conduit 25 comprises a box made preferably of sheet-iron.v To the under side 0f it is hinged a door 39 at 40, but

one hinge being shown and that in Fig. 5.v

As only a fragment of the conduit is shown in Figs. 1 and 2 they would appear in dotted lines.

Ears 4l are secured to near each end of the conduit-door and levers 42 are pivoted to them. These levers extend to and pivot to the rock-arm 43, which is pivoted in a bearing 44, secured to the frame or portion of it. This rock-arm is adapted to be engaged by the arm 45 in the direction of the arrow or to move it up, which is secured to the mainy shaft J, (see Fig. 6,)'which the instant a tie is cut operates to open the door, swinging it downward to its position in dotted line. This allows the tie to fall onto the 'support 46. In falling it is guided by the supports 24 and the guide-strips 26 at each end of the conduit to fallin the crotch-stud 22 and across the fingerpinion. As soon as the arm '45 leaves the rock-arm 43 the-door is closed by the weight of the lever and rock-arm. The supports 24 are secured to the blocks 47, which form an integral portion of the cross-yoke 1 and 1 'of each auxiliary frame, Figs. 3, 8, 9, and 12 showing this yoke and fragments of it larger than in Figs. 1 and 2.

In Fig. 12 a support `is shown riveted to an vupwardly-extending projection of the block. Thesesupports are secured to and sustain the conduit above the center of the machine. The instant a tie falls from the conduit the door closes and the feeding mechanism again starts up. The next instant the weighted holdinglever 46o (see Fig. 3) is moved down onto it by the quadrant-cam 48, which engages a rock-arm 49, which is pivoted to a boss on the cross-yoke 1 and also to levers 50, which are adjustablysecured to the holding-lever 46". The cam is adapted to bring the holding-lever down onto the wire with a sudden and quick movement. A notch 51 is cut in the ends of these levers, which registers over the wire and thereby holds each end of the tie down in the crotch of the stud, thus preventing its jumping or moving out of the crotch-stud 22'whi1e it is being looped and until the grippingblock 52 grips it between itself and the block 47. An instant after the holding-levers engage the wire the loop is formed on each end of the tie by the looping mechanism, as above IOO described. The instant a'loop is made at each end of the wire the gripping-block 52, which is pivoted to the cross-yokes in a posi- -tion which will enable its face to swing squarely against the face of the block 47, is moved by a semicircular cam 53 to grip the wiresl adjacentto the loops-that is, the body of the wire and the returned ends, as shown in Figs. 8 and 9. The block 52 is provided with a renewable steel face-plate 52, which is secured to it by screws or rivets. The face of -the block 47 is likewise provided with a IIO similar block 54. These blocks have to be frequently renewed, as they wear out rapidly. To the under side of the block 52 I secure a rubber cushion-block 55 and a metal plate 56, which latter is engaged by the face of the cam 53. Normally the cam carries the block 52 against the face of the block 47; but it cannot do so with the wires between them. Consequently a yielding. element is required between the cam and the block. The cam 53 is secured to the main shaft, but is set di- -rectly opposite to the cam 21, as shown in Fig.

3, which allows it to, engage the block the instant the cam 21 leaves the guide-block 4, which is the instant theloop is formed. The next instant block, 52 is forced to grip the ends of the tie, holding them rigidly. At the same time the pinion 5 engages the teeth of the gear 10, and the guide-block, rack-fingers,

Iv I l l a 544,rea

pinion, and crotch-stud are rotated, preferably three complete revolutions, this being the preferable proportion of the pinion 5 to the teeth on one-half of the circumference of the gear 10. The loop is of course rotated with the guide-block and its parts, as it still rests in and around one side of the crotch-block, as shown in Figs. 4 and 9, and three complete twists are given the ends between the loop and the gripping-block, as shown in Fig. 7. As soon as the cam 53 leaves the gripping-block it falls back and the tie is released. The next instant the arm 57 (shown more clearly in Fig. 3 than in Figs. l and 2,where it is partially hidden by the rock-arms 58 and 59, and in Fig. 3 it is shown in dotted lines, as it is behind the cam 48) contacts with the rock-arm 58, which is pivoted to a boss on the yoke. This arm is also pivotcd at 60 to the end of a rock-arm 59, which is also pivoted to a boss on the yoke. The rock-arm 59 extends under the ties. Its end is turned upward and extends above the wire. The arm 57 carries the arm 58 downward and moves the free end of the rock-arm 59 upward and outward away from the machine. These arms work in uni son with the arms 62, which are secured to the main shaft near its center and revolve with .it to discharge the ties from the machine, the

tie being acted on at four points of its length by these arms.

To a projecting end of the rock-arm 58, I attach a spring 63, the opposite end of which is secured to the frame. This spring throws the levers 58 and 59 back to their normal position after the arm 57 leaves the lever 58. rlhe end arms 58 are the principal ones in discharging the ties, as the central ones are employed to prevent the central portion of the ties from lagging behind. The supportsl 46 are adapted to support the central portion of the tie in alignment with its ends. They are secured in any convenient manner to the sides of the frame. I have shown the rack and finger-'pinion of the looping mechanism separately in Figs. 19 and l1. In Figs. l and 2 the iiange of the finger-pinion is shown thicker than in Fig. l0. This is done to raise the ends of the wire high enough above the guide-block to be distinctly seen. I secure a strip 6l, of which I only show a fragment in Fig. 4, to ears G4 on the guide-block. This strip extends over the edge of the rack and holds it down against the block, the under side of this strip and the bottom of the block forming the guide-surface between which the rack reciprocates.

The essential functions of my machine are, first, the automatic and intermittent feeding of a wire to predetermined bale-tie lengths into the machine; second, mechanism for cutting the predetermined lengths from the wire; third, mechanism for forming a loop on each end of said lengths; fourth, mechanism for twisting the ends adjacent to the loops to sustain the loop, and, fifth, mechanism for discharging the ties from the machine.
