Generally stated my invention consists of a frame adapted to be mounted on the ord1- narybaling chamber, which frame is pro vided with springs onv its upper side, which of said frame, thus giving to said frame a' vertical and longitudinal movement. The frame proper consistsof a telescoping frame and has mounted on eitherside a pair of needles so designed that when the frame is drawn outwardly by means of the plunger,

the needles will be driven across the frame I one pair on each side of a head block. One pair carries the wires across for the new bale andmay be termed the threading needles, while the other pair carries the wires across the balingchamber from the opposite side into .the tying mechanism for completing the old bale and may be termed the binding needles. The head block is providedwith pins designed to engage dogs pivotally mounted on said frame by means of which the frame is set in motion and causes an automatic means to connect with the plunger by means'of which plunger the telescoping frame is pulled outwardly, drawing the needles across the frame and carrying the wire therewith as explained. After the frame has been pulled outwardly a predetermined distance the means connecting with the plunger is automatically disengaged and the frame is drawn inwardly by means of a spring which causes the tying mechanism to operate, thus tying the ends of the wires and completing the halo.

Referring to the drawings in detail, I .have used the reference numeral 10 to'designate the baling chamber'as a whole, which may be of any of the ordinary constructions, and 1-1 designates the main frame of the baling and tying mechanism which main frame is provided at its top and bottom with a telescoping frame but as the top and bottom arethe same, a description of the top which is clearly shown in Fig. 4. will be suflicient for both. Pivotally mounted on the top of the frame 11 substantially at its center are a pair'of arms 12 which arms are pivotally connected at their outer ends by means of a pair of short diverging links 13. Pivotally connected to the arms 12 are a second pair of links 14 which links are pivotally connected at their outer ends to anauxiliary frame 15 which auxiliary frame extends entirely around the baling chamber. Mounted on the under side of the upper side of the frame 11 are a pair of steel springs 16' to permit ofa vertical movement of the frame 11.

-' On the top and on the bottom of the baling chamber are suitable coil springs 17, which are connected at one end to the frame 15, and at their opposite ends to the main frame 11, for the purpose presently to be described.

18 designates a chute through which the hay is fed into the baling chamber.

19 designates the head block which is provided with pins 20 which pins are deslgned to travel in the grooves 21 in the balmg chamber but where it is desired to use my invention with a baling chamber of the usual construction, that is, one without the grooves, I provide the head block 19 with spring pins as best shown in Fig. 16. The head block is inserted in its place. The hay is then fed into the chamber through the chute which forces the head block longitudinally of the frame, the pins on the head block traveling .in the grooves 21. After the head block has thus been moved longitudinally in the baling chamber sufliciently, the pins engage the dogs 23 for a purpose presently to be described. Thedogs 23 are arranged in pairs, two on each side one above the other and are pivotally connected to the frame 11 by any suitable means such as the pin shown, the upper dog being connected to the lower one by means of a link 23 as best shown in Fig. 9. At a point spaced apart from the connection to said frame, said lower dogs are pivotally connected by means of a link 24 to one end of the link 24*. The said link 24 is provided at its opposite end with a curved bearing shoulder, which end is pivotally connected to a suitable bracket 24. Said bracket is rigidly secured to the main frame 11 by any suitable means. Pivotally connected to the bracket 24 and the link 2-1 is an arm 24 which arm is provided at its upper end with a lug having a curved bearing shoulder designed to engage the curved bearing shoulder on the 'link 24, by means of which the

links

24 and 24 are forced into the position shown in dotted lines in Fig. 9 when the arm 24 is forced forwardly. The lower end of the arm 24 is bifurcated and is adapted to be engaged by the lug 26 on the rod 27. The

links

24 and 24" are provided with shoulders 24: designed to engage each other to prevent said links from being folded in but one direction, thus preventing the dogs 23 from 'l')e'ing tripped until said links are forced into the position shown in dotted'lines in Fig. 9.

lVe will call the end on which the chute 18 is mounted through which the hay is fed the rearward end and the opposite end the forwardend as best shown in. Fig. 2. As the head block reaches the main frame 11 and the pins engage'the dogs 23 the ntire frame 11 is moved forwardly a short distance which allows the pivotally mounted dogs 32 tit Will

frame 11. by any suitable means. When the dogs 23 are engaged by the pins on the head block the main frame 11 is forced forwardly a short distance which causes the lugs 33 on the rods 34 to disengage the lugs thus allowing said dogs to be forced into engagement (through a longitudinal opening in the sides of the baling chamber) with the notches in the plunger by means of coil springs 35. It will of course be understood that the plunger has a reciprocatory movement and as it starts on its outward stroke it engages the dogs 32 (that is assuming of course that they have been released as before stated), thus drawing the auxiliary frame 15 outwardly for a purpose presently to be described. After the tying and binding operation is completed and the dogs 23 released the main frame 11 returns to its normal position by means of the compression springs 28 which springs are wound on the rods 28. The said rods are rigidly secured at one end to the side of the main frame 11 and slidably mounted at the opposite end in the brackets 29, the latter end being provided with a nut to limit the rearward movement of the frame 11. The brackets 29 are rigidly secured to the side of the baling chamber one on each side by any suitable means. The head block is held in its proper position until after the needles (presently to be described) are driven across the baling chamber and back to their normal position. This is accomplished by means of the

links

24 and 24 and the arm 24 heretofore described. After the binding and tying operation is com leted it is necessary that the dogs 23 be tripped, thus releasing the head block and allowing the frame 11 to be returned to its normal position by means of the springs 28 above described. This ll accomplish by means of the rods 27 which are rigidly secured to the auxiliary frame 15 on each side near the lower edge thereof, which rods extend forwardly past the main frame 11 and are provided with a lug 26, but as the construction and operation of each are the same. a description of the operation of one will be sufficient for both. As the auxiliary frame 11 is drawn forwardly by means of the mechanism heretofore described, the lug 26 on the rod 27 forces the arm. 24 into the position shown in dotted lines in Fig. 9, while the

links

24 and 24 are in the position shown in heavy lines in the same figure. The lug 26 is positioned on the rod 27 so that it will slide past the bifurcated end of the arm 24", thus allowing said arm to return to the position shown in heavy lines in Fig. 9. After the lug 26 has passed the arm 24, said arm swings into a position shown in heavy lines, Fig. 9, where it will be engaged by said lug on its return. The lug 26 is positioned on the rod 27 that said lug will engage the arm 24 just before the auxiliary frame 15 has reached its backward limit of movement, at which time the needles have been withdrawn and returned to their normal position. The lug 26 then engages the arm 24? and by means of the. shoulders on said arm and the link 24*, the links 24* and 24 are forced into the position shown in dotted lines in Fig. 22, thus tripping the dogs 23 and releasing the head block. The head block is then forced through the baling chamber past the dogs 23 by means of the action of the plunger on the hay within the chamber. As soon as the head block is completely past the dogs 23 the steel spring-24 on the

links

24 and 24 return said links to their normal position, thus returning the dogs 23 to their normal position at which position they are again engaged by the next head block, for again starting the mechanism in operation. The

arm 24 is so arranged that it will slide past the lug 26 before said lug has reached'its backward limit of movement and then swings into the position shown in heavy lines in Fig. 9 whereby the same operation may again be repeated. After the plunger has traveled outwardly a certain distance the dogs 32 are automatically disengaged from the plunger by means of the rollers 36 on the end of the arms 34- which arms are rigidly secured 9 to the frame 11 as best shown in Fig. 5, and the auxiliary frame 15- is then returned to its normal position by means. of the said springs 17 one of said springs being posi: tioned on the top of the main frame and the other on the bottom of said main frame, one end of each of said springs being secured to the main frame in any suitable manner and the opposite end connected to said auxiliary frame. During this outward travel of said plunger and before the dogs are released by means of the rollers 36,- the threading and binding operation is performed, and during the inward travel of said auxiliary frame by means of the springs 17 as above described the needles are returned to their normal position, the tying operation completed, the (logs tripped and the head block released.

The mechanism by which the threading and binding operation is performed, I will now described.

There are two pairs of needles, one pair on each side of the framewhich needles are pivotally connected at'their outer ends to the links 13 as best shown in Fig. 5 and are provided at their inner ends with a suitable groove for holding a looped wire as best shown in Fig. 12. As the operation of both needles in each pair is the same, a description of the operation of one needle in each pair willbe sufficient for both, Referring to Fig. 5 and applying the same designation to the forward and rearward ends of the baling chamber as in Fig. 2 1 will designate the pair of needles which are on the forward side of the head block, thebinding needles,

while that pair on the rearward side of thev head block, I will designate as the threading needles. -With this understanding as to terms, 37 designates the binding needles and 38 the threading needles.

It may be assumed that the machine is in condition for operation, spools of wire 39 having been arranged on one side of the machine as shown in Fig. 1 and the end of the wire in each case passed forwardly over the rollers 40 and across the baling chamber to the clamp58 as best shown in Fig. 5, and assuming that a sufficient quantity of bay has been placed in the baling chamber and the head block then placed therein, the wire would then be in they position shown in Fig. 18. The ,plunger having a reciprocatory movement forces the hay ahead of the head block and the head block through the baling chamber and by means of the hay ahead of the head block the wire is forced into the position shown in Fig. 19. After the wires reach this position it is necessary. that sufficient slack be drawn into the. wire as shown in Fig. 20, so as to provide an endof sufficient length to reach back across the baling chamber and form a tie as shown in Fig. 21.

This is accomplished by the means new to .be

described.

Secured to one side of the frame 11 are brackets 42 on which is slidably mounted a vertical shaft 43 on which shaft is secured upper and lower arms 44 which arms are provided with upwardly extending ends designed to engage the wire 41. Said shaft is provided at its upperend with a-short arm .45 (as best shown in Fig. 10) designedto rest on the bar 46 which bar is slidably mounted on the side of the frame 11 near one end and is slidably connected at its opposite end to a short arm 47. The arm '47-- with a cam portion 46 which is designed" to engage the arm 45 and-to raise theshaft 43 when said bar is slid forwardly by means of the head block engaging the lower end of thearm 47. lVhen the shaft is thus raised the arms 44 are necessarily raised upwardly and engage the wire 41. After-the operation described above is completed thehead block engages the lower end of the arms 48 by means of which the bar 48 is moved .backwardly, thus causing the shoulder. 48

on the bar 48 to engage the arm 45 thus partly rotating the shaft 43 and throwing the arms 44 out to the position shown in heavy lines in Fig. 10. by means of which L the wire is drawn out of position as shown in Fig. 20, thus providing sufiicient slack for extending the end of the wire across the baler and tying in the form shown in Fig. 21.

Pivotally mounted on the side of the frame 11 is a dog 50 (Fig. 11) which is designed to engage the notch in the bar 46 to prevent said bar from sliding backwardly imtil the proper time. Immediately following the engagement of the dogs 23 by the head block 19 which moves the frame rearwardly a short distance as before described,

-the lugs 33 on the rod 34 are caused to release the dogs 32 allowing them to engage the-plunger 30 by means of which the auxiliary frame 15 is drawn outwardly causing the needles and the arm 52 to travel across the baling chamber. However, it is timed so that just as the arm 52 is moved inwardly the dog 53 engages the pin 53 on the arm 54. (Fig. 42 and pulls the bell crank lever 55 ,inward y. By means of the rod 54 which rod connects the arm 54 with the bell crank lever 55 (Figs. 3 and 4) the link 57' which is pivotally connected to the fulcrumed levers 57 is drawn upwardly thus opem'n the clamps 58 ("presently to be described and releasing the wire therefrom. At the same time the lug 59 is forced downwardly by which the dog 50 (Figs. 3 and 11) is released allowing the bar 46 to return to its normal position by means of the spring 60, thus returning the arms 44 to their normal position by means of the spring 60 on the shaft 43. This operation is completed just as the binding needles engage the wire. To hold the wire away from the arms 44 when the shaft is returned to' its normal position, I provide the stationary spring arms 61 which are rigidly secured at one end to theside of the mainframe 11 by any suitable means s u'ch as the bolts shown (Fig. 2) and are provided at their free or opposite ends with aflat surface on which the wire rests. Just preceding the releasement ofthe wires from the clamps the movement of'the needles 37 are timed so that the ends of the needles 37 strike the wire and carry it acrossto the twister, (presently to be'-described). The end of the needle beinggrooved, and the movement .Of the needles 37 being timed to strike the wire before it isfully released from the clamps 58, a loop is formed in the wire which will prevent it from slipping over the ends of the needles as it is carried across to thejtwister. As the needles 37 are traveling across'the'baling chamber it is necessary needles 38 carry the end of the'wire leading 'that the clamps 58' remain open until the mamas from the spool to the clamps 58. For holding the clamps 58 open until this time, I provide a dog 61 which is pivotally mounted on the .top of the frame 11 and is provided with an outwardly extending arm 62 as best shown in Fig. i. It will be seen from this that when the clamps 58 are open for releasing the wire by means of the operation heretofore described, the lug 63 will be moved rearwardly sufficiently to engage the upper end of the bell crank lever by means of which the clamps 58 are held in their open position and in which position they remain until the end of the bar 52 travels across the baling chamber and engages the extending lug 62 on the dog 61 by means of which the dog is forced out of engagement with the bell crank 55, thus allowing the clamps 58 to close. It will of course be understood that the mechanism is timed to be released and the clamps closed at the time the end of the needle reaches said clamps so that the end of the wires may be clamped in place. The needles 38 start across. the baling chamber simultaneously with the needles 37 and it is therefore necessary that just as the needles 38 engage the wire that the wire be cut-and held on both sides of the place where cut. The end cut away (that is the wire going around the bale) is clamped in place and so held until the needles 37 carry the opposite end of the wire going around the bale across the baling chamber where the two ends are twisted, while the other end (that is the end leading from the spool) is clamped and held until the end of the needles 38 engage it and forces it out of the clamp. For accomplishing this I provide the arm 54 with a bifurcated-end as best shown in Fig. 4, in which bifurcated end is designed to travel a bell crank lever 55 as best shown in Figs. 3 and 4, and when the bifurcated end of the arm 54 is moved inwardly by means of the arm 52 the wire is clamped in place and cut by the means now to. be described.

Rigidly secured to the side of the frame 11 near the upper edge thereof is-an out wardly exten-tiing bracket 8i and pivotally mounted on the outer end of said bracket is the outwardly extending arm of the bell crank lever as best shown in Fig. 3.

Pivotally connected to the bell crank lever 55 means of a suitable pin as best shown in l 'ig. 1+!- and are provided with 'a' beveled o:- sharpened edge as best shown in Fig. 4. When the upper end of the bell crank lever 55 is moved inwardly by'means .of

the bifurcated arm 54 the link 85 is moved downwardly, thus forcing the inner or are two clamping devices which are positioned in a line with the path taken by the wires 41 so as to engage the said wires when operated as best shown in Fig. 14*. As the construction and operation of bothof these clamping mechanisms are the same a description of one will be sufficient for both. These may be termed a compound clamp as they are designed to clamp the wire on each side of the blade. One of said clamps being held in closed position independent of the other and both being designed to be closed or clamped at the same time. Rigidly secured to the side of the frame 11 is a slotted casting 87 provided with jaws 88 and is so positioned that the blade 86 is designed to travel in its upward and downward movement in said slot. Mounted on the blade 86 is a jaw 89 designed to engage the jaw 88. The jaw\ 89 is provided at its lower end with an inwardly extending portion 90 'wl1ich is provided with a suitable opening through which is inserted a rod 91 which rod extends through a suitable opening in the blade 86 at its upper end and is provided at its lgwer end with a coil spring 92 and a suitable nut or rivet for holding said spring in place by means of which said jaw is connected to the blade 86. The portion 90 .is provided with an arm 93upon which is adapted to rest a slotted jaw 94 as best shown in Figs-14 and 14. The said aw 94 is slidably mounted on the casting 87 by means of the slot and pins as shown in Fig. 14. One of said pins is provided with a cap 95 for holding said'jaw against outward movement while the pin 96 which is rigidly secured to the casting 87'holds said jaw in its upright position. The jaw 94 is provided at its lower edge with an inwardly extending portion designed to be engaged by thearm 93 for forcing said jaw upwardly and clamping the wire in place. Rigidly secured to the/lower inward extendingportion of the jaw 94 is a suitable rod which extends .dmvnwardly through a suitable opening in the arm 93 and is provided with a coil spring and a suitable nut or rivet at its lower end for holding. said spring in place as best shown in Fig. 14. As the inner end I of the blade 86 i'snoved upwardly by means of the downwardly movement of the link 85 as heretofore described the

jaws

87 and 94 are carried upwardly, thus clamping the wire between said jaws and the jaws 88 on either side of the blade as it is out. It is necessary that the endof the wire is held between the

jaws

89 and 88 until the end of the needle strikes the wire and forms a loop (as best shown in Fig. 15) for carrying the wire across to the opposite side. ,By providing the spring 92 it allows the wire to be forced out of the jaws by means of the needle but holds it sufficiently tight that a loop is formed before it is forced out. The

jaws

89 and 88 are'held in a closed position until the bar 52-has traveled inwardly suiiiciently forthe inner end of said bar to engage the arm 62 on the dog 61 thus releasing the dog 61 from the bell crank lever 55 at which time the jaws 89 are moved downwardly through the connection de scribed by means of the spring 52 (Fig. 4c) and at the same time the clamps 58 are closed by the same means but through a connection presently to be described.

It is necessary that the bifurcated arm 54 j be disengaged from the bar 52 after said bar has traveled inwardly a short distance. This I accomplish by means of the dog 53 j which dog is provided with a curved arm 53 which arm travels in the path of the pin 56* which. engages the curved arm 53 and forces it out of engagement with the pin -53 on the arm 54. When the bar 52 has returned to its normal position the spring 53 returns the dog 53 to its normal position, in which position it is adapted to again engage the pin 58 on the bar 54.

It is necessary that the end of the wire held between the

jaws

94 and 88 should be.

held in a clamped position until the needles 37 have carried the wire from the opposite side of the baling chamber to the twister. This I accomplish by means ofa dog 97 which is pivotally mounted on a suitable support secured to the'side of the frame 11 and is designed to engage a suitable notch in the jaw 94 for holding it in a closed position, in which position said jaw will be held until the twisting operation is commenced when it will be released by means .of the beveled lug on the periphery of the wheel 66, which lug is designed to engage an arm on the dog 97 and forces it out of engagement with the notch in the jaw 94.

After the dog has been released from the jaw 9% the said jaw is returned to its normal or open position by means of the spring shown.

The clamps 58 on the opposite side of the baling chamber which have been heretofore referred to are two in number mounted one above the other directly in the path of the needles 38. As the construction and operation of both of these are the same a description of one will be sufficient for both.

Rigidly secured to the side of the frame 11 is a casting 98 which is provided at its upper end with a U shaped inwardly extending portion having bearing surfaces 99.

Slidably mounted on said casting by a means inverted U shaped portion similar to that in the casting 98 and having bearing surfaces 101 which are designed to engage the bear- 100 is given a sliding motion with respect to the casting 98 and by means of which the bearing surfaces 101 are forced upwardly against the bearing surfaces 99 for clamping the wire in place. At the time the end of the needles 38 reach the clamps 58 the end of the bar 52 reaches the arm 62 on the dog 61 thus disengaging the said dog from'the pin 63 at which time the bell crank lever 55 is forced outwardly thus forcing the link 57 downwardly and closing the clamps by means of the spring 52 which spring is best shown in Fig. By providing the U shaped clamps 58 it permits the needles to be driven in and the wire clamped without clamping the needles.

After the free end of thebinding wires have been drawn across the baling chamber by the needles 37 it is necessary that these ends be twisted together with the ends cut from the wire leading from the spool by the means above described. I will now describe the means and mechanism for twisting these ends together.

Mounted on the side of the frame 11 opposite from the side on which the clamps 58 are mounted are two twisters which are mounted in a level with the path taken by the wire and directly in the path taken by the needles 37. As the construction and operation of both of these twisters are the same, a description of one will be suflicient for both.

Secured to the frame 11 in any suitable manner is a casing 65 in which is rotatably mounted a hollow cylindrical wheel 66 which is provided on its periphery with an annular groove for mountin the same in the casing 65. The wheel 66 is provided with a stub shaft 67 which extends outwardly through a bracket 68 on which is securely mounted a gear wheel 69. Mounted in the wheel 66 are a pair of pivoted jaws 7 0 which are provided with diverging arms which diverging arms 71- extend outwardly through slotted openings in the stub shaft 67. Slidably mounted on the stub shaft 67 is a beveled collar 72 by means of which said jaws are opened and closed. For actuating said collar I provide a bell crank lever 73 which is pivotally connected at one end by means of a short link to the collar 72 and at its opposite end to a rod 74 which rod is provided with

lugs

75 and 76 as best shown in Figs. 1, 5, 6 and 7. The jaws as shown in Fig. 6 are in a closed position and show the wires still being held after the twisting operation is completed memes and when the jaws are in this position the bell crank 7 3 would of course be in the position shown in heavy lines in Fig. 6. When the jaws are open they will be in the position shown by dotted lines as will also the bell crank 73. At the time the needles 3'? reach the jaws of the twister with the end of the wire to be twisted it is necessary to provide means for closing the jaws. For accomplishing this I provide a rack 7 7 which is rigidly secured at one end to the side of the auxiliary frame 15 and extends backwardly past the main frame 11 and is provided near its rearward end with a series of gear teeth. Near its forward end is securely mounted a lug 78 which is designed to en gage the lug 76 on the rod 74 by means of which the collar 7 2 is slid outwardly on the shaft 67,. thus opening the jaws 70 and releasing the twisted ends ofthe wire. During the time the lug 78 travels from the lug 7G to the lug the twisting operation is performed by the means now to be described. Rotatably mounted on the bracket 68 is a gear wheel 79 designed to'mesh with the gear wheel 69. The gear wheel 79 is provided with the usual pawl and ratchet mechanism as best shown in Fig. 8. The small gear wheel is designed to be engaged by the gear teeth on the rack 77 as above described, both in its outward and rearward travel but by means of the pawl and ratchet device the large gear wheel 7 9 which meshes with the gear wheel 69 is only rotated during the backward travel of the rack 77 by means of which the jaws are rotated and the ends of the wires twisted. The mechanism is so timed that this twisting operation takes place while the lug 78 travels from the lug 76 to the lug 75 as before stated. It will be understood that the rack 77 is forced backwardly by means of the springs 17 which springs are attached to the auxiliary frame 15 and the main frame as before stated. The jaws 70 are U shaped on the inside, so that the needles may be released and the wire retained as best shown in Fig. 17. It will be understood that the jaws 70 are positioned so that the wire coming from the spool and going around the bale passes between the jaws.

The head block 19 is provided with suitable transverse grooves as best shown in Fig. 9 in which grooves the needles37 and 38 travel in crossing the baling chamber and by means of which grooves the hay or other material is kept from engaging the needles thus giving a clear and unobstructed path to the needles.

It will be understood that the auxiliary frame 15 may be provided with means for automatically connecting and disconnecting said frame with the plunger rod as will be done on some of the machines. in actual practice, instead of the plunger proper as shown a on its upper and lower sides To limit the backward movement of the i auxiliary frame 15 I provide stops 103 which are rigidly secured to the baling chamber as best shown in Figs. 2 and 4.
