BALE-TIE MACHINE.

SPECIFICATION forming part of Letters Patent No. 570,555, dated November 3, 1896.

Application ned April 25.1896.

To (LZZ whom, t 71u11/ colmar/f.:

Be it known that I, SAMUEL KIMBALL, of Lawrence, Douglas county, Kansas,have invented certain new and useful Improvements in Bale-Tie Machines, of which the following is a full, clear, and exact description, reference being had to the accompanying drawings, forming a part thereof.

My invention relates to bale-tie machines; and my object generally is to produce a machine of this character which shall be strong and compact of construction and very rapid and reliable and entirely automa-tic in its operation. Other special objects will hereinafter appear, and be pointed out in the appended claims.

In order that the invention may be fully understood, I will proceed to describe it with reference to the said accompanying drawings, in which- Figure l represents a plan view of a baletie machine embodying my invention. Fig. 2 represents a side elevation of the same. Fig. represents, on an enlarged scale, a crosssection taken on the line 1c uof Fig. l. Fig. -1- represents, on the same scale, a cross-section taken on the line .t .2c of Fig. 2. Fig. 5 represents, on the same scale, a cross-section taken onthe line 3/ y of Fig. 2. Fig. 6 represents, on the same scale, a cross-section on the line .e of Fig. i. Fig.` 7 represents, on a much larger scale, an elevation of the wire-bending shaft and in section certain parts relating thereto. Fig. S represents a face view of a disk which operatesV in conjunction with said shaft. Fig. 9 represents a longitudinal section of the wire-twisting shaft and its connections. Fig. 10 represents detailed vi'ews of the wire-clamping jaws.V Fig. 1l represents, on a smaller scale than Fig. 9, a view partly in elevation and partly in vertical section, the section being taken through the twisting-shaft and its connections. Fig. 12 represents, on a larger scale, a horizontal section taken on the line ay a of Fig. 1l, and also shows a horizontal section of one of the wire actuating or moving d evices. Fig. 13 is a vertical section taken on the line l) b of Fig. 1l. Fig. 14 is an inner face view of the guide-plate for the wire where and when it is bent to form an eye or loop. Fig. 15 is a perspective view of the serial No. 589,137. (No mafia.)

same. Fig. 16 is a cross-sectional view of one of the wire-carriers.' Fig. 17 is a plan view of a'portion of the machine not illustrated in Figs. 1 and 2, owing to the fact that the great length of the machine has made it necessary to show said figures as broken. Said ligure also shows the means for automatically disconnecting the completed bale-tie from the carrier at a predetermined point. Fig. 18

represents a cross-section taken on the line t In the said drawings, where like parts are I indicated by corresponding reference-numerals, 1 designates a longitudinal frame of suitable length, which is of skeleton form preferably. Itis mounted uponsupportng legs or standards at each end and carries superposed at one end a bed-plate 3.

4 designates the power-shaft, which with all other shafts hereinafter mentioned, is j ournaled in suitable bearings mounted upon either the bed-plate or the frame of the machine. Said shaft extends transversely of the front end and a suitable distance above lthe bed-plate, and carries at its outer end fast and

loose pulleys

5 and 6, respectively, and a balance-wheel 7. Between its bearings 8 a beveled gear 9 is rigidly mounted upon it, and this bevel-gear meshes with a similar gear l0 upon the longitudinally-extending shaft 1l, journaled in bearings l2 and 13 at its opposite ends. Said shaft in turn at a point adjacent to the bearing 13 carries a double gear consisting of a large wheel 14 and a smaller wheel or pinion l5. The wheel 14 meshes in turn with a smaller cog-wheel 16, keyed or otherwise secured upon the hollow wire-twister shaft 17, which shaft will be hereinafter more particularly described.

The pinion l5 meshes with av cog-wheel' 18 of equal diameter, preferably'with the cog 14, and mounted rigidlyupon a shaft- 19,

IOO

journaled in said bearings upon the bed-plate. Said shaft 19 is a short shaft, and is employed merely to carry the large cog-wheel 1S, which projects downwardly through an opening in the bed-plate, and a very small pinion 20, indicated by dotted lines, Fig. 6. Said wheels 1S and 2O are preferably formed integrally, and the pinion meshes with the large wheel 21, mounted rigidly upon a longitudinallyextending shaft 22, journaled in bearings 23 upon the bed-plate. The large cog-wheel 1S meshes in turn with a slightly smaller cogwheel 24, which is mounted rigidly upon the longitudinally-extending shaft 25, arranged below the bed-plate and j ournaled at its opposite ends preferably in the frame 1 or bearings thereto attached. At its rear end it carries a beveled gear 26, which meshes with a small gear 2T upon a short vertical shaft 2S, journaled at its lower end in a-n extension or arm 29 of the rear-end bearing of the shaft 25, and at its upper end in the bearing-sleeves :30, of a vertical bracket 31, mounted upon a cross-bar 32, secured upon the rear end of the frame 1. Said bracket 3l, at its lower end, is providedwith a pair of longitudinal slots, and extending through the same and into the cross-bar are the vertical clamping-bolts 234. By this means the bracket can be adj usted longitudinally upon the machine.

Arranged in longitudinal alinement with the bracket 31, and mounted either adjustably or rigidly upon a cross-bar 35, secured rigidly and transversely upon the frame by a bolt or bolts 3G, is a similar but oppositelydisposed bracket 37, and journaled in corresponding sleeves 38 of said bracket is a short vertical shaft .39, which is disposed just above the rear end of the bed-plate 3. Mounted rigidly upon said shafts 28 and 3f), and between the sleeves thereof, so as to prevent vertical movement, are the similar sprocketwheels 40 and 41 respectively, and connecting said sprocket-wheels is the endless sprocket- At points equally distant from each other said chain is provided with a pair of links, with which are cast integrally the outwardly-disposed plates 43 and 44, respecchain 42.

tively, and secured to said plates are similar bale-tie-feeding devices 45 and 4G, respectively. Each comprises a plate 47, secured to a plate 43, a slotted block 4S, secured to plate 47, a bar 49, pivoted at 50 within the slotted block, and provided at its opposite ends with the oppositely-proj ecting hooks 5l and 52, and

the spring 53, secured within said vblock and l engaging said bar with a yielding pressure,

so as to normally hold the hook 5l with its free wire feeders or carriers is atable or plate 55. It is of length to extend from the front sprocket-wheel 41 toward the oppositepr rear sprocket-wheel a distance slightly exceeding thelength of the longest bale-tie to be formed, which in practice will be about nine and onehalf feet, and this table or plate is arranged at the outer side of that portion of the sprocket-cl1ain nearest to the longitudinallyextending twister-shaft, and the arrangement of the parts is such that the hook 51 of each wire feeder or carrier travels in the horizontal plane represented by the axis of the said twister-shaft. Said table or plate is preferably in the form of an angleplate, and its vertical arm is bolted yor otherwise rigidly secured t-o the upper Aends of a number of standards or brackets 56, which are bolted, as shown at 57, upon the cross-bar 35, and a pair of similar crossbars 5S, which extend transversely of and are secured to the frame 1 at equal distance from each other and from the

bars

32 and 35, preferably. Said bars 58, and also the bar 35, have their front ends, that is, the ends projecting toward the side of the machine where -an operator stands, extended beyond the corresponding side of the frame 1 and formed with upwardly-projecting longitudinally-alined ribs 59, so as 4to provide between them channels 60, to receive the baleties while being bundled in the customary order to advance the hook 51 of said bar los IIC'

at the proper time, however, I secure upon the i strip G1 a strip 63. The front end of this strip, and also the front end of the strip 61, is curved or formed as shown at 64, so that when the rounded end 65 of the bar 49 comes in conta'ct with it, as indicated in Figs. 1 and 12, said bar will be pivotally operated and the hook 51 advanced and the spring 53 repressed simultaneously. Said bar will remain in this position until the rear or discharge end of the strip 63 is reached by the carrier, at which point the complete tie is discharged from the hook and dropped down upon the cross-bars 35'and 58, as hereinafter more particularly explained. This is accomplished owin-g to sition projecting forwardly beyond the said strip 63, as indicated clearly by full lines in Fig. 17- When retracted, this point or outer end is brought back to the vertical plane of the front face of said strip, so that the eye or loop of the bale-tie which travels against the face of said strip and therefore cannot move rearwardly with the retracting-hook, is released, and the wire being cut at the same time, (as hereinafter to be explained,) the complete tie drops down upon the cross-bars 35 and 5S.

In order to make the disconnection of the carrier and the wire more positive and reliable, and therefore to absolutely prevent any possible chance of the looped end of the wire being drawn upon the strip 63 by the retracting-hook, I have employed the overhanging hook 54:, hereinbefore described. The front or outer end of said hook occupies the plane of the front face of the strip 63, so it is obvious that upon the withdrawal of the hook 5l the loop finds an unresisting bearing-surface both above and below the hook, and therefore must absolutely be disconnected with the hook. In order to make this withdrawal of the hook still more positive and reliable, so that entire dependence need not be placed in the spring 53, I have also secured to the rear strip 62 the adjustable block 66, from which projects forwardly into the path of the arm 52, overhanging the strip 62, the beveled shoulder or cam 67. This tripping-block is arranged just beyond the adjustable end of the strip 63, so that as the heel of said hook 62 clears the end of said strip 63 its free end com-es in contact with said inclined shoulder 67 and is forced forward positively and reliably, as illustrated clearly in dotted lines, Fig. I7. It will thus be seen that the length ot' the strip 63 determines the length of the bale-tie turned out by the machine. In case it is desired to increase the length of the baletie, I may either replace said strip 63 with a longer strip or I may secure upon the strip 6l one or more additional short strips 63, which practically forms a continuation of the strip 63, of course adjusting the trip-block 66 accordingly.

In Fig. 20, I have provided other means for making positive the disconnection of the loop or eye of the wire from the hook of the carrier. Then used in connection with the structure disclosed in said figure, the stationary or overhanging hook 5-.L of the carrier will be dispensed with, and in lieu thereof one or more arches 55 will be secured by any suitable means in the position relative to the longitudinal table or plate 55. (Shown in said Fig. 20.) Said arch or arches at the front side of the table will be provided with an offset 55", that Ithe vertical arm or arms 55C, depending therefrom, may not be in the way of the hook of the carrier and the eye or loop of the wire engaged thereby. In other words, by thus offsetting these arches at the front side of the table a space is left between the latter and the arches through which the hook mayhave free and uninterrupted passage.

55d designates a longitudinal bar which extends beyond the rear or discharge end of the strip 63 a suitable distance, and also is arranged slightly above and parallel with the same so as to provide a slot 55e between them, through which said hook can barely pass, so that when the said hook is operated in the manner hereinbefore described in order to disconnect it withthe eye orloop of the Wire it is withdrawn through said slot 55 without the corresponding movement of the eye or loop, because the latter finds a positive and unresisting bearing-surface in the faces of the strip 63 and the bar 55d. This disconnection takes place a fraction of an instant before the baletie is severed from the wire at its opposite end, and the depending arms or portions 55c of lthe arches insure its vertical descent upon the cross-bars 35 and 5S.

At the workin g side of the table or plate 55, located vertically upon the rear end of the bed-plate 13, is a casting or standard 68, and said casting projects a suitable distance above the plane of the twister-shaft and sprocketwheels. Its inner end is arranged about in the plane of the working or front face of the strip 63, and at its front side and side adjacent to the twister-shaft it is provided with

bearings

69 and 70, the bearing 69 being arranged to receive the diametrically-enlarged end 71. of a shaft 72, journaled also in the bearings 70, and the axis of this shaft occupies the same plane as the axis of the twistershaft. shaft eccentrically of its center are the pins 73 and 74, which also extend loosely through registering

openings

75 and 76 of a rotatable disk 77, journaled also in the bearing 69.

The shaft 72 reciprocates at times, so as to alternately advance and retract said pins through said disk in order to receive the baletie wire and release i-t after the formation of the eye or loop, and as it is desirable that the loop be relatively immovable during the withdrawal of these pins, around which it is tightly clamped in its formation, I have provided the disk 77 with a peripheral annular or segmental rib 78, which engages the corresponding groove in the bearing69. This arrangement permits the disk to rotate with the shaft, and at the same time affords astationary surface against which the eye or loop of the wire bears when the pins are withdrawn. It is obvious, therefore, that this disk or its equivalent cannot be dispensed with by extending the enlargement 71 to the end of the bearing 69, owing to the fact that when it is moved longitudinally outward to withdraw TOO Projecting from the inner end of said y IIO the pins a cavity equal to the diameter of the If this should happen, j

the wire-feeding device or carrier secured to the chain might fail to engage the loop in its passage, and the operation of the machine would have to be suspended until the loop or eye was brought to its proper position in the path of said carrier. lts proper position is vertically between the opposing faces of said disk 77 and the plate SO, bolted or otherwise rigidlysecured to the end of the casting or standard (5S, as shown most clearly in Fig. 14. Said plate is provided at its inner side with a longitudinal groove S1, and communicating therewith with alongitudinal slot 82, extending from a point in advance of the axis of the shaft 7 2 clear through the opposite end of the plate, and said plate at the closed end of said slot is beveled, as shown at 82, in a line substantially concentric to the axis of the sprocket-wheel 41. Below said groove the plate is of uniform thickness, and rests against the bearing, but above said groove its thickness is diminished, so as to form between the bearing and the diminished portion of the plate a passage or space S3, in order to permit the free end of the wire to swing upward and around, as indicated by dotted lines, Fig. S, as the eye or loop is beingformed. This groove, which is horizontal, is opposite the axis of the shaft 7 2, and is of sufficient width to permit the eccentrically-disposed pin 7 3 to circulate within it. The plate is also provided with a circular groove Si, within which the other eccentricall 7-disposed pin 7l travels during the formation of the eye or loop. rl`he pin 7 3 is in practice the fulcrum-pin, while the pin 7 4C performs the function of a lever to bend the wire round the fulcrum-pin, and by reason of the fact that said fulcrum-pin is eccentrically disposed relative to the axis of the shaft 72, it is obvious that the center of the loop or eye formed is in longitudinal alinement with the body, shank, or straight portion of the wire. In other words, by causing' the fulcrum or pin around which the wireis bent to travel in a circle, the opposite sides of the loop are equaldistances from the shank or straight portion of the tie, and not more at one side of the shank than at the other, as is the case where the end of the wire is fed in a straight line under a relatively fixed or immovable pin and bent round the same. To illustrate this more clearly reference is to be had to Figs. 7 and 8. ln said figures the parts are relatively ar ranged in their proper positions to receive the wire which extends in a straight line below the pin 7 3 and above the pin 7l.

It is obvious that when the shaft with thc disk 77 rotates in the direction indicated by the arrow, Fig. 8, through about one hundred and eighty degrees, or half a circle, the pins consequently assume the position shown in dotted lines in said figure, the pin`73 at this time being as much below the axis of the shaft and the pin 74 being as much above the axis of the shaft. as they were above and below the saine, respectively, before such rotatable movement took place, and consequently it is obvious, owing to the fact that the pin 73 is now below the plane of the wire, which is the same as the axis of the shaft, that the loop or eye formed in said wire must project as vmuch below it as above it. Therefore, a more symmetrical and durable loop or eye is formed in the end of the tie, as the strain upon it when in service will be equally distributed between the twisted portions of the wire.

Referring now to the tubular or hollow twister-shaft 17, which is arranged opposite the space between the casting or standard 68 and the plate SO, it will be noticed that at its front or receiving end it is j ournaled in a bearing 85, and that it is journaled a short distance rearward of said bearingin a similar bearing 8G, between which bearings and upon said shaft are mounted the cog-wheel 16 and the collar S7, the former rigidly upon the shaft, and the latter slidingly but not rotay tably mounted upon the shaft and bearing against the front side of the bearing 86, and said wheel 16 and collar S7 are held yieldingly a slight distance apartby means of the interposed spring 88, spirally encircling the shaft, for a purpose which will be hereinafter explained. The rear or discharge end of said shaft carries rigidly a -collar or sleeve 89, which in turn is secured within the disk 90, which is journaled rotatably in a bearing 91 upon the bed-plate.

The bearingdisk is provided at diametrically-opposite points with the elongated openings or slots 92, .which register with slots 93 in the collar S0, and pivotally mounted upon bolts 94 which bridge said slots,are a pair of levers 95, an d said levers are pivotally connected by the links 9G to a collar 97,c0nnected to slide upon and rotate with the shaft 17, as shown clearly in Fig. 0, said collar being disposed when in its normal or inoperative po back against the bodyT portion or shank-to grasp said shank and end and clamp them firmly together, during the rotation of the twister-shaft in order to twist said portions of the wire upon each other and thus complete the formation of the eye or loop, said the twin arms 100 clamp the portions of the wire firmly and reliably, as will be readily understood.

102 designates a bifurcated clutch-arm which loosely engages an annular groove of the clutch-collar 97, and is secured at its opposite end to an arm or head 103 of abracket 104,bolted or otherwise rigidly secured to an inverted U-shaped frame 105,which is pivotally mounted at its lower end upon a rod 100, secured to a bracket 107, bolted to and depending from the under side of the bed-plate, as shown clearly in Fig.. 5. Said frame is hereinafter termed a swinging frame from the fact that it rocks back and forth in operation. ln order to cause this motion, I project a bolt vertically upward through the slot in the middle of the bridge or horizontal portion of the swinging frame and engage its projecting end with a retaining-nut 108, and

Amounted rotatably upon the lower or headed end of said bolt is an anti-frictional roller 109, and said anti-frictional roller, by means of the retractile spring 110, connecting an arm 111,bolted to the bracket 104,with an arm 112,l

bolted to one of the iixed bearings-8', is held with a yielding pressure against the face of the cam-wheel 113, mounted rigidly upon the shaft 22, the face of said cam-wheel comprising a short vertical portion 114, terminating at its opposite ends in an abrupt shoulder 115 and a gradually-receding shoulder 116, which tapers gradually to the base of the shoulder 115. By this construction it is obvious that as the cam-wheel rotates in the direction indicated by the arrow, Fig. l5,

the antifriction-roller rides up on the inclined shoulder or surface 116, and the swinging frame consequently is forced rearwardly. This operation in turn, owing to its connection with the clutch-collar, forces the latter rearwardly upon the shaft 17, and consequently, owing to the resistance of the stiff spring 97, advances the toggle and the collar to which rit is pivoted rearwardly upon the shaft slightly'. The continued movement of said cam,and consequently said clutch-collar, then overcomes the resistance of and compresses the spring 97, and thereby causes the clampin g-jaws to come together upon the shank and the end of the wire, as hereinbefore explained, in advance of the detachable nozzle 17 at the rear end of the shaft, said nozzle being made detachable owing to the fact that there is frictional contact of the wire with the end of the shaft and it may be easily replaced in case of undue wear. i The wire is thus clamped firmly by the jaws at the same time that the antifrictional roller rolls upon the portion 114 of the cam, and during the time the said surface and roller are in engagement the rapid rotation of the twister-shaft twists the wire and completes the formation of the eye or loop in the end of the wire. Immediately this is accomplished the roller clears the abrupt shoulder 115 of the cam, and the spring 110 being unresistcd retracts and swings the frame back described. Owing to the fact, however, that' the wire is shortened very slightly by the twisting operation, it is obvious thatj the clamping-j aws must either slip slightly or else must move rearwardly to accommodatefsuch retraction in the length of the wire betweenl the point where it is clamped by said jaws and the opposite end of the relatively fixed eye or loop, which cannot move longitudinally, owing to the fact that it is twisted around the pins 73 and 74 of the wire-bending shaft 72. As the slippage of saido'jaws would make the twisting operation unreliable, I therefore have interposed between the cog-wheel 16, fixed relatively to said shaft, and the collar 87 ,fixed relatively tothe bearing 86,the spring 88, which yields and permits the shaft to move longitudinally a sufficient distance only to accommodate the contraction of the wire.

117 designates a cam-wheel which is mounted rigidly upon the shaft 22 vertically below an inclined shoulder 118 of the approximately horizontal arm of the bell-crank lever 119, said bell-crank lever being pivoted as at 120 just above the bed-plate near its working side and rearward of the bearing 01 of the twisting-shaft. At its upper end it is provided with a bifurcated clutch-arm 121,which engages loosely the annular groove 71a of the enlargement 71 of the wire-bending shaft 72, in order that with each revolution of said Vshaft 22 said cam will engage and cause the bell-crank lever 119 to swing in the direction indicated by the arrow, Fig. 4, and thereby move the wire-bending shaft in the direction indicated by the arrow, Fig. 7, and consequently withdraw the pins 7 3 and 7 4 through the openings and 76 of the disk 77, so as to positively and reliably release the eye or loop formed in the end of the wire upon them, as hereinbefore described, and then permit the retractile spring 122, (see Fig. 4,) attached at its opposite ends to the free end of said lever and to a rod or bracket 123, fixed to the frame or bed-plate of the machine, to cause said lever toresume its original position, and consequently again project said wire-bending pins through said disk.

Mounted rigidly upon the shaft 22, just rearward of the cam 117, is a similar camwheel 124, and said cam once in each revolution of the shaft engages ashoulder upon the depending arm of a bell-crank lever 125. Said bell-crank lever, like the lever 119, is also arranged to operate in a vertical plane, being mounted upon the short shaft 126, journaled at its opposite ends in the bearingbracket. 91 of the twister-shaft, and in the standard 68, erected upon the bed-plate. Said shaft is arranged sufficiently above the horizontal arm of the lever 119 so as not to interfere with its operation, as illustrated in Fig. 4. The opposite end of said leveris pivotally connected to the lower end of a bar`127, bolted in turn to a vertical rack-bar 128,

IDO'

which engages a cog-pinion 129 on the wirebending shaft 72, said pinion being arranged between the bearings 70 of said shaft and of less width than the intervening space between said bearings, in order 'toadmit of the reciprocating movements of said shaft. The rackbar is guided in its vertical movements in longitudinal grooves 130, formed in said bear ings, so that it is at all times held reliablyin engagement with said pinion. Said bellcrank lever is also pivotally connected, as at 131, to the upper end or rod 132, which extends vertically downward through an opening in the bed-plate. A retaining nut 133 is mounted at its lower end, and spirally encircling the rod is an expansive spring 134,which bears at its opposite ends against the bottom of the bed-plate and said retaining-nut, in order that said shaft may be rocked back to its initial position immediately the cog-wheel 24 becomes disengaged with the lever. Thus it will be seen vthat with each operation of the shaft 22 the wire-bending shaft not only reciprocates, but also oscillates, due to the mechanisnr just described, and it is to be observed by the relative arrangement of the cam-

wheels

117 and 121 that the first-named cog-wheel does not cause the retraction of the pins until an instant after the wire-bending operation has been completed by the rotatable or oscillatory movement` of the shaft in one direction, and it is also to be observed, and will hereinafter more clearly be shown, that during the interval of time between the retraction of the pins due to the action of the cam 117 and said oscillatory movement of said shaft the twisting operation takes place, and immediately after this operation the clamping-jaws release the wire, the pins are retracted, and the shaft rotated back to its original position, and immediately it reassumes this position, which is about the same instant as the withdrawal of the pins, the cam 117 releases the lever 119, and the spring 122 again advances the pins above and below the wire as it is being drawn through the machine by the carrier, which automatically engages the eye or loop the instant it was released by the clamping-jaws and by the retraction of said pins.

132' designates another cam which is mo unt ed rigidly upon the shaft 22, and said cam once in each revolution of the shaft comes in contact with and elevates the lever or arm 133, pivotally mounted as at 134C upon a bracket 135, bolted to the bed-plate. Said lever is arranged to swing in a vertical plane adjacent to the rear face of the casting or standard G3, and at its opposite end projects under the table or plate 55, being preferably provided with an upwardly-projecting head or enlargement 13G at this point, and said head or enlargement is provided with a longitudinal groove into which is adjustably and snugly mounted the upwardlyprojecting knife 137, said knife being arranged at the working or front side of the table or plate 55 just at the rear or discharge end of the guide-plate 80, as indicated by dotted lines, Figs. 11 and 12, 'its upper or cutting edge in operation just lapping the cutting or lower edge of the upper or stationary knife 138, whichis secured in a recessed block 139, bolted or otherwise secured to the casting or standard 68. Said knife may be adj usted longitudinally by means of a screw-bolt 140 to accommodate wear or for any other reason.

After each cutting operation, which takes place just after the advancement of the pins of the bending-shaft, in order to complete a tie disconnected an instant before from the carrier or feeder by means hereinbefore described, and to release the end which is to be bent back upon itself in the formation of the loop or eye of the next succeeding tie, the knife by gravity descends to its original position by reason of the disconnection with the lever of its actuating-cam.

As it has been found in practice that the gravity of, or spring pressure upon, the knifecarrying lever 133/ cannot always be depended upon when the machine is working at its highest capacity to depress the knife with suicient quickness after each cutting operation, l contemplate employing in place ofthe cam 132 a cam 1322, provided with an annular groove 1321), which will be engaged at all times with the antifrictional roller or pin 133, projecting laterally from the knife-carrying lever 133. By this construction it is obvious that the knife is returned to its depressed position positively and reliably. The cam 132 or 132T may also be employed, or an additional cam 111 may be mounted upon the shaft 22 in order to operate the counting mechanism, that is, the mechanism for separating each bunch of ties in predetermined or desirable numbers from the ties of the next succeeding bunch automatically. To accomplish this, I mount rigidly in the frame, below the bed-plate or the brackets depending from the same or secured to the frame, the short longitudinal shaft 112, and journaled loosely upon the same is a sleeve 143. (Shown in dotted lines, Fig. A large ratchet-wheel 1&4, in this instance containing fifty teeth, is mount-ed rigidly upon one end of said shaft, and a small cog-pinion 145 is mounted rigidly upon the opposite end of said sleeve and meshes with a large cogwheel 11G, journaled loosely upon the stubshaft 147, suitably supported. ,Said wheel is provided in this instance with sixty teeth, and at one side with a fixed dog 148, which dog once in each complete revolution of said wheel pivotally operates the lever 149, and causes the same, through the medium of the link 150, to pivotally operate a tie-distribut ing lever 151, mounted rigidly upon a shaft 152, journaled at its opposite ends in bearings 153, secured to the under side of the cross-bars 35 and the rearmost cross-bar 58, as illustrated in dotted lines, Fig. 17.

IOO

The tie-distributing lever 151 is arranged adjacent to the front or left-hand side, preferably, of the cross-bar 35 and sup erposed standard 56, and mounted rigidly upon said shaft and also arranged in the same position relative to the cross-bars 58 are similar tie-distributing levers, whereby when one is operated the others are operated simultaneously. Each comprises, essentially, a body portion which normally occupies a horizontal position and projects beyond the plane of the front side of the table or plate 55, and an inclined arm 151, which, when the tie-distributing levers are elevated to the position shown in dotted lines,Fig. 3, project rearwardlyand upwardly beyond the plane of the vertical face of the said table or plate, and thereby positively and reliably insures that any and all ties which may be formed and released while the disconnecting levers are in this position will be deflected outwardly and forwardly and go to complete the requisite number of ties in the bundle which is moved outwardly upon said cross-bars by reason of the changed position of the body portions of said levers; that is, the ties previously formed and lying upon the said cross-bars of the body portions of said levers just in advance of the standards 56 are by the pivotal operation`of said levers shoved bodily forward. In practice these levers are raised so slowly that probably five or six ties, more or less, will be formed by the time they reach their elevated position and all these ties will be deflected forward, as described.

The counting mechanism is operated by means of alever 154, which is journaledloosely upon the sleeve 143, and projects below and in the path of the cam 141, which once in each revolution of the shaft depresses said lever, and through the medium of the spring-actuated pawl 155, carried thereby, rotates the ratchet-wheel 144 the distance of one step. The relative number of teeth employed upon said ratchet, said pinion, and said cog-wheel is such that it takes two hundred and iifty revolutions of the shaft 22 to elevate the tiedistributing levers to the position shown in dotted lines, owing to the fact that one dog 148 only is employed, and consequently cach bundle contains just exactly two hundred and iifty ties. In case two dogs 148 are employed and arranged at diametrically-opposite points each bundle would obviously contain one hundred and twenty-five ties. As 4the dog clears the heel or rear end of a lever 149, the latter and the elevated tie-distributing levers immediately by gravity assume their original position and the next two hundred and fifty ties successively formed are acted upon, as described. It is obvious of course that instead of the pawl-'and-rachet mechanism shown the saine object could be accomplished by employing its mechanical equivalent, a worm-shaft and connections. The spring 154u eleva-tes the arm 154 after each depression.

The device for straightening the wire as it mounted upon an arm or extension 157 of the bed-plate. Said plate is provided with depending iianges 158, which embrace the opposite sides of the arm or extension 157 of the bed-plate, and rests near its rear or inne`r end upon iianges 159 of the bed-plate, and near each outer or front end is pivotally mounted to operate in a vertical plane upon the transversely-extending bolt 160, carried by the arm or extension 157, as shown clearly in Figs. 2 and 18. VSaid plate 156 is provided in its upper side with a groove 161, which extends in longitudinal alinement with the axis of the tubular or hollow twister-shaft 16 and with a similar groove in the upper end of the extension 12 of one of the bearings 12. Said groove 161 is intersected at two points by the transversely-extending grooves 162, within which are mounted plates 163 and 164, provided each at one end with upwardly-projecting parallel guide-flanges 165, and at their opposite ends with depending arms 166, through which extend the adjusting-bolts 167, which are screwed into the plate 156, and are provided with fixed collars or enlargements 168 at opposite sides of the depending arm 166, whereby when the bolts are operated in one direction or the other the plates are moved back or forth upon the plate 156. Between the iianges 165 of said plates are iitted snugly tempered steel wear-plates 169, provided with longitudinal series of holes 170, through certain of which extend securing-bolts 171, engaged by clamping-nuts 172 at their projecting ends, whereby said wear-plates may be adjusted longitudinally a-nd secured at any desired point.

The plate 163 is of greater length than the plate 164, so that its wear-plate may be disposed at the opposite side of the longitudinal groove 161 of the plate to the wear-plate of plate 164, in order that said wear-plates may bear upon opposite sides of the wire, and' thereby insure the removal of Vallkinks or bends in the same, that it may pass to the twister-shaft perfectly straight.

The longitudinal grooves are. occupied by the guide-strips 173, provided in their upper edges with narrow and shallow longitudinal guide-grooves 174, through which the wire extends, as illustrated most clearly in Fig. 18, and bearing upon the upper sides of said strips, and thereby capping and closing the open side of said groove or grooves are the capping-strips 175, and said strips are held firmly and reliably in position by means of the clamping-brackets 176, secured in posi- IOO tion in turn by screw-bolts 177 engaging the plate 156, or in any other suitable manner. In order to straighten the wirelpreliminary to its passage through said closed, groove, l arrange upon the plate ,156 at its frontend two series of grooved rollers 178, the rollers of one series being arranged alternately or opposite the spaces between the others in the customary manner. This arrangement of rollers removes substantially all the kinks or bends from the wire as it is fed into the machine; but in order to be sure that the wire is perfectly straight, I have provided the narrow and shallow guide-groove intersected at two or more points by oppositely disposed wear-plates, and means for adjusting said wear-plates in the same or the opposite direction, in order that the wire may be perfectly straight and in the proper condition for after manipulation by the machine.

In order to maintain the plate 156 in its proper position relative to the axis of the twister-shaft, in ease of faulty casting or any other cause which may tend to raise one end of the guide-groove 174 slightly higher or lower than the other, I have provided two bolts 15G, which extend vertically downward through said plate and bear at their lower ends upon the arm or extension 157 of the bed-plate, in order that by adjusting these bolts or set-screws the said plate may be pivotally operated upon the bolt 1GO, carried by said arm or extension, and reliably and firmly secured in such position, as will be clearly understood by reference to Figs. 1 and 1S.

In the practical operation of the machine the power-belt is shifted from the loose to the fast pulley, and thereby rotating the powershaft 4, imparts motion through the medium of the beveled gears 9 and 10 to the shaft 11, and from said shaft through the train of gearing hereinbefore described to the twistershaft 1G, cam-shaft 22, and the wire-feeding shaft 25, as the shaft which through the medium of the vertical shaft 2S operates the endless chain will hereinafter be termed, the

Vwire preliminary to this operation, however,

being rst passed through the wire-str( ightening device, the twister-shaft, and between the pins of the wire-bending shaft until its end is adjacent to the stationary knife 13S. (See Fig. 11.) The arrangement of the cams upon the shaft 22 is such that the knife-lever is iirst caused to assume its operative or cutting position, as shown in Fig. 3, then the eam-wheel124 operates bell-crank lever 125, and through the medium of the rack-bar 128, connected to the same, rotates the wire-bending shaft 7 2 and causes the pins of the latter to bend the projecting end of the wire back toward the twister-shaft and upon its body portion or shank. Immediately this operation is completed the cam-wheel 113 swings the frame 105, and thereby advances the clutcheollar upon the twister-shaft and causes, through the operation of the toggle, the clamping-jaws to bind firmly between them and upon each other the shank and the free end of the wire, as hereinbefore described, and this operation being completed, the rotation of the twister-shaft and the clamping jaws twists the said portions of the wire upon each instant the cam-wheel 117 operates the lever 119 and withdraws the clamping-pins from engagement with said loop or eye, as hereinbefore set forth, and simultaneously with this operation one of the tie-carriers has assumed the position shown in Fig. 1, and the heel of the arm 52 coming in contact with the alined end of the strip 63 represses the spring 53 and projects the hook 51 through the longitudinal slot S2 of the guide-plate SO and also through the adjacent eye or loop at the end of the wire. The relative position of said hook and said loop just previous to their arrangement is shown most clearly in Fig. 12. The carrier eontinously moving in the direction indicated by the arrow, Fig. 1, now feeds the wire positively and reliably from the reel and through the intervening devices, and at the instant it reaches the position shown in dotted lines, Fig. 17, the cog-wheel 132 again lifts the knife and severs or cuts the wire, and a complete bale-tie drops down upon the cross-bars 35 and 58, as indicated in said iigure, where they accumulate successively as the operations described are repeated 4until the requisite number for a bundle has been made and have been shoved bodily forward by the distrib ating-levers. The operator then grasps this loose bundle of ties and places it in the longitudinally-alined grooves 60, where the ties are bunched and securely tied together by wire bands in the customary manner.

In practice the operation of this machine is so rapid, so positive, and so reliable that from IOO IIO

thirty-five to forty ties per minute are manufactured, each tie-carrier successively engaging the eye or loop in the end of the wire and drawing the same from the reel. Owing to the friction with which the wire passes through the straightening device, itis obvious that i111- mediately the wire is cut by the knife to complete a bale-tie the movement of the wire instantly ceases and the projecting end thereof remains in the proper position relative to the pins of the bending-shaft.

Vhiie I have described and illustrated a particular mechanism, it is obvious that slight changes in form, proportion, or arrangement of parts may be made, or mechanical equivalents employed, without departing from the spirit and scope or sacrificing any of the advantages of my invention.
