compressed into bale formation will gradually move rearwardly through the machine and at the same time carry with it baling wires which, when the bale is complete, will encircle it and be automatically tied about the same, means being also provided for cutting the wires and retaining the same in po-.

sition to be similarly encircled and tied about a succeeding bale, the latter in its delivery from the machine actuating signaling mechanisms to indicate the completion of a bale, all as will be hereinafter more particularly described and claimed.

In the accompanying drawings, forming apart hereof, Figure 1 is a plan view of the rear portion of a baling press equipped with my improved tying mechanism, showing the needle bars in their initial position, that is, withdrawn from the baling chamber; Fig. 2 is a side elevation of the mechanism shown in Fig. 1, the housings being removed to more clearly show the mechanism; Fig. 3 is a side elevation of the forward end of the machine showing the drivmg and safety release mechanisms; Fig. 4 is a rear view showing the signal mechanisms which notify the operator when the baling process has reached the stage to cease feeding material into the machine; Fig. 5 is a central, longitudinal, vertical section show- "ing the plunger and the feeder lever operating mechanism; Fig. 6 is a fragmentary plan sectional view with the twister mechanismshown in its initial position ;Fig. 7

is a view similar to Fig. 6' but showing the twister mechanism in the position which it assumes just previous to the final twisting operation: Fig. 8 is a fragmentary view in side elevation showing the twisting mechanism and wire cutter in their normal position; Figs. 9 and 10 are face views ofthe twister in different positions; Fig. 11 is a, fragmentary plan section of a portion of the mechanism shown in Fig. 6, showing the I method of bringing the baling wire through the twister; Fig. 12 is a similar view showing the twisting operation at a stage where the knife has released a heretofore held end of the baling wire and also shows the wire running from the needle bar to the hook as having been drawn across one edge of the movable knife; Fig. 13 is a detail sectional view of the forward end of the drive shaft showing the safety releasing means in section; Figs. 14 and 15 are respectively an edge view and a face view of the knife, and Fig. 16 an enlarged detail sectional view on the dotted line 16, 16, in Fig. 1.

In said drawings similar. reference numerals indicate similar parts, the portions marked 20 indicating a baling chamber which is built up of suitable metal plates and angle irons to form a rectangular box-like structure upon which at its forward end is mounted the drive wheel, 21, connected by a suitable gearing to the large gear, 22. A pitman, 23,-is pivoted at 24 to gear 22 and carries at its opposite end a ram or plunger, 25,- the face of which is slotted, as at 26,

to receive the needle bars, 27, comprising a curved frame, which at a suitable time are caused to pass therethrough. A lever arm,

'28, is mounted upon a shaft, 29, and is suit ably supported in an A-frame member, 30.

A presser-foot, 31, is pivotally mounted, at 32, to the lever 28 and, at 33, is pivotally connected with a rod, 34, also carried by and as the plunger or ram 25 courses back and forth in the baling chamber the presserfoot 31 is caused t6 rise and fall and during its fall pushes the hay which has been introduced into the hopper 36 into the baling chamber to be in turn acted upon and compressed by the next actuation of the ram. A folder, 37, is pivotally mounted upon a shaft, 38, and extends across the top of the baling chamber. Secured to said shaft 38 is acrank, 39, (Fig. 2) suitably connected by means of a rod, 40, (Figs. 2 and 3) with an L-shaped lever, 41, pivotally mounted at 42, to the side of the machine. Aboss,

43, is mounted upon the gear 22, and at each revolution causes'the end, 44, of the lever 41, to be depressed. This causes a downward movement of the folder 37, which tucks in any loose ends of hay which might otherwise protrude, thus tending to maintain a smooth surface to the bale.

In Figs. 1 and 2, the mechanism is shown in its initial position, and Fig. 1 in particular shows the baling wires, 45, of which there are three, each leading from a receptacle, 46, to a tension mechanism, 47, mountedupon the rear end of the needle bars 27. A frame, 48 is pivotally mounted, at 49, to a cross strut, 50, carried upon the frame of the baling chamber, and is caused to swing thereupon by the drag link 51, car ried by the plate, 52, which is bolted to the frame 48, and the opposite end of which is pivotally connected to a mutilated gear, 53. A drive shaft, 54, is driven at its forward end by a pair of beveled gears 55, 56, Fig. 3, the gear 56 being carried on a stub shaft, 57, which carries a pinion, 58, meshing with, the large gear22. At the rear end of the shaft 54 is another pair of beveled gears, 60, 61, Fig. 2, the gear 61 being a compound gear, the spur gear portion of which, 62, meshes with a gear, 63, on a shaft, 64. The mutilated gear 53, loosely mounted upon the shaft 64, is associated with a gear, 65, and lock, 66, Figs. 1 and 2, said gear and lock being carried upon theshaft, 67. Upon the shaft 67' are also mounted three beveled gears (not shown) in housings 68, 69, 70, meshing with corresponding gears (not shown) mounted upon shafts 71, 72, 73, which will hereafter be called twister shafts, inasmuch as it is the actuation of these shafts which causes the twisting of the baling wires about the bale, the operation of which will be hereinafter described.

On the lower end of the shaft 64, is mountedv a master cam, 74, which when in rotation actuates a knife-controlling shaft, 75, and a hook-controlling shaft, 76, (Figs. 2'. 6 and 7). The shaft 75 has mounted at its lower end a roller, 77, Fig. 2, which engages a cam channel, 78, formed upon the edge of the cam 74, said engagement causing the raising and lowering of said shaft 75 and consequently the wire-cutting knives, 79, secured in frames 79 mounted on said shaft, the operation of which knives will be hereinafter described. The shaft 76, has a lever, 80, mounted upon its lower end which carries a roller, 81, adapted to engage a camchannel, 82, in the upper surface of the master cam 74, said engagement causing the oscillation of the hook-bar, 83. Mounted upon the shaft 76, and keyed thereto by a key, 84,

is an arm, 85, connecting the shaft 76 with the hook-bar 83, said hook-bar 83 being pivotally connected at 86, to said arm 85, the action of the cam 82 on roller 81 causing the bar 83 to be reciprocated through an aperture, 87, in a bracket, 88, mounted upon the twister frame casting, 90, Fig. 7.

By referring to Fig. 2 it may be observed that the hook-bars 83 and the mechanisms associated therewith are three in number, and therefore the description of one set of mechanisms and the operation thereof will suflice as all are identical in construction and operation.

The machine, as viewed in Fig. 1, is in position to start a bale, there being three needle bars 27 each carrying a baling wire 45, Fig. 4, which bars course through the guide 27 the wires passing between duplicate sets of rollers, 91, 92, of the tension mechanisms 47, tension at the time being, applied tothe wires from such mechanisms over the idlers 93, 94, 95, idlers 93 and 94, being rotatably mounted in the needle bar 27 while idler 95 is mounted upon the frame of the baling chamber, the outer end of each of said wires being held, as shown in Fig. 11, between the face of a knife 79 and a wire holder plate, 96. Therefore, as the baling process progresses the. wires 45 lying across the path of the bale, will be forced farther back with each succeeding oscillation of the pitman 23 until such time as the operator has been signaled to discontinue feeding the machine. WVhen the bale has been formed the wires 45 have been. forced backtwisters 98, bringing the slot, 100, into the position shown in Fig. 10. The hook-bars 83 have meanwhile been advanced, as shown in Fig. 7, and the needle bars 27 have carried the wires 45 through the slots, 101, formed in the side of the baler chamber, and which register with the slots 26 in the ram 25 as seen in Fig. 5, the latter slots being sufiiciently large to admit the needle bars, and the cam 82, through its engagement 'with the roller 81, on the lever 80,. now

causes a return movement of the hook bar 83, Fig. 6 and 11, the hooked end, 103, of which catches wire 45 and pulls it through opening, 104, in twister plate 104, when it slides into the slot of the twister. The opposite ends of the wire bale are now threaded through the twister, Figs. 10 and 1.1. The mutilated gear 53 continues in its revolution and the tooth portion, 53, engages the pinion 65, when the twister gear 99 is' caused to further rotate, which twists the site end gears, 99, Fig. 9, in mesh with the wires into the shape shown in Fig. 12, at which moment the knives 7 9 are raised through their engagement with the cam 7 8, and the end of the baling wire which has heretofore been held between the knife and its-holder plate is released. The needle bar has started on its return movement and has drawn the wire'45 backwardly against the raisedendlOG of the knife 79, which during its raising movement has brought the notch 107 into the path of thewire 45. The knife 79 now starts down again and severs the wire, and the end thereof connected to the needle bar and lying in notch 107 is drawn down with the lowering of the knife and is clamped between the knife 79 and its holder plate 96.- This clamping of the wire secures the same sufficiently to withstand the compressing action between the looped wires and'the ram and the succeeding bale being formed forces the wire backwardly as hereinbefore described.

It is desirable that the wires carried by the needle-bars shall be loosely held in same upon the forward movement of the bars to permit the free running of the wires, and therefore the rollers 91, 92, are kept a considerable distance apart by means of a spring-controlled yoke 91 mounted upon a rod 93' having a flat face against which the yoke bears, and which yoke carries the roller 92. Upon the return movement of the bars,

however, it is essential that the wires shall be held taut, and therefore I provide a spring-mounted frame 47in the path of travel of the lowermost needle-bar, so that as it moves forwardly the arm 92 thereon will contact with said frame 47' and be held in one position until it reaches the offset portion 47 thereof, whereupon, when said bar starts to return, said arm will be thrown in a reverse position by contacting with said offset portion, which operation turns the rod 93 upon which said arm is mounted, so that said yoke will be forced toward roller 91, at the same time carrying roller 92 with it, and thus grip the wire sufficiently to hold it in tension until arm 92 has traveled across frame 47 toasimilar ofi'set at the opposite end thereof, when the tension on said wire becomes released.

With reference to Figs. 1, 2 and 4, it will be noted that T have mounted upon one side of the baling chamber, ashaft 110, in plates 111 and 112. On the upper end of said shaft is secured a disk 113, carrying upon its upper surface a crank 114, to which is secured a link 115, said link being fastened at its outer endto an indicator arm 116, which is pivotally mounted upon a plate 117, said plate having a mark upon its upper edge to notify the operator when a-bale has been formed sufiiciently to cease feeding material to the baler, said arm 116 being caused to oscillate back and forth across the plate 117;,

' vice, 140.

by the mechanism just described. An audible signal 118, is also provided, which comprises a lever 119, pivoted at 120, to a plate 121. As the shaft revolves, due to the contact between the rearwardly moving bale being formed and the semi-circular toothed plates 122. 123, constituting a trip-wheel, the disk 113, carrying the roller 124, revolves, said roller engaging the end of the lever 119, causing said lever to rock upon its pivot 120 and to be suddenly disengaged, thereby striking the gong or audible signal 118. The plate 123 of said trip wheel is preferably mounted upon shaft 110, and is provided with holes (Fig. 1) in which studs I 8 may be inserted, against which plate 122 announcement will not take place until a greater quantity of material has been baled, and by which I amv enabled to arrange for the formation of bales of varying lengths and weights as desired, and which mechanism when set for a desired size of bale insures that bales-of that size shall be uniform.

-A spring-actuated plunger. 126, actsas a buffer to overcome the action of a pull spring, 127, which is connected between a lug 128 and the lever 119. The mutilated gear 53 carriesupon its lower side av dog 129 which abuts one end of a pivoted lever 130, 'the opposite end of said lever carrying of the hook 131, causing said hook to slide in its bearing 133, and pull the lever 130, from its engagement with the dog 129, thereby releasing said gear, 53, so that as the hook 184, contacts with dog 129the mutilated gear becomes actuated to make another revo lution.

The twister shafts 71, 72, 73. (being identical a description of one will suflice for all) are composed of two pieces 71 and 71 joined as shown in Fig. 6 by a spring de- The portion 71 which carries the twister gear 99 is clamped at its opposite end to a casting 141 suitably recessed to ac commodate a spring-controlled bolt 142, said bolt passing through a plate 143 having an inturned end 144 held against a flattened portion 145 of the shaft 71 A. spring 146 surrounds thebolt 142 and is compressed between the head of said boltand the bot tom of the recess in the casting 141, tension being regulated'by adjustment of the nut if said studs are placed closer together such 147 If for any unforeseen reason the twister should become jammed and thereby create an undue strain, the tension of the spring 146 would be overcome and the plate 143 would be sprung out of engagement with the squared end of the shaft 71 and said shaft 71 would then be allowed to revolve without causing a corresponding revolution of the friction gear 99. Bars 148 are-carried by a yoke 149 secured to the baler frame, said bars 148 being connected by a link 150, which is actuated by a cam 151 cast upon the top surface of the master cam 74. It is necessary that the bars 148 should lie in line with the slots 101 while the needle bars are bringing the bale wires through preliminary to the twisting operation and that they be lowered to allow the bale wire to disengage therefrom at a predetermined time. Springcontrolled fingers 152 are mounted upon opposite sides of the baling chamber and the ends 153 thereof project through suitable openings slightly into the baling chamber and are for the purpose of preventing surging of the hay as the ram is withdrawn. It is desirable that the slots 26 be closed on the side next to the twisting mechanism, except at the time when the needle bars pass therethrough, and to this end 1 have mounted upon a shaft 154 plates or doors 155 actuated by a cam 156, (Fig. 2), which causes the reciprocation of a bar 157 mounted on the lower end of shaft 154 and communicating with said cam. These doors 155 prevent any unnecessary dust or chafi from entering the twister mechanism to clog'it up.

The knife 79 (Figs. 14 and 15) is preferably made of tool steel and its upper end has a projection 158 provided with a face which is slightly inclined toward the cutting edge 107, said face 158 being rounded to allow the wire to remain in position while the knife is being elevated. At the time that the wire falls into the notch 107, the end of said wire nearest the needle bar would be freed were it not for the fact that the rib p 159 held the same and forced said wire be tween the knife 79 and its holder plate 96.

The safety device shown in Fig. 13 shows the gear 55, loosely mounted upon the drive shaft 54. At the end of the drive shaft and shears in case an overload should occur on shaft 54, whereupon the bolt 163 would be severedfand the driving mechanism could continue to revolve gear 55 without revolving the shaft 54, thereby obviating the liability of damage to the machine, the bolt in m sses use being an ordinary stove bolt. This makes a very suitable driving connection and may be readily replaced in case it becomes sheared.

If for any reason the bolt 163 becomes sheared, the spring 166 forces said bolt against the plate 169, causing said plate to be rocked upon its pivot 170, and carrying with it the bar 171, attached to the lever 172, at 173-. To the lower end of the lever 172, is attached a clutch rod, 174, leading to a suitable clutch (not shown) communicating with the driving gears. I Therefore, as the lever 172-is drawn forward the clutch will be released by the movement of said rod and the driving gears will be stopped. A push-spring 175 tends to maintain the lever in either its operative or disconnecting position, being in the nature of a snap-switch, that is, as the pivotal point 176 passes the line intersecting the pivotal point 177, and the point 178, it will be maintained in either position due to the spring 175.

By the construction and arrangement of mechanisms described I produce a baling press capable of efficiently and rapidly forming and automatically binding bales, and one in which the various mechanisms for feeding and compressing the material, drawing the wires thereabout, tying and cutting the same, and announcing the completion of a bale, with safety mechanisms for positively stopping the operation of the machine in-case of emergency, as well as other features, are so arranged and timed as to codperate in entirety and either synchronously or in sequence perform the vacious steps necessary to the formation and binding of a bale from loose material, which I demonstrate in practice is accomplished I effectively and very rapidly at a material saving in time and labor.
