The lever isp end to a link I2. The opposite end of the link I2 is pivoted to a bell crank I3 fulcrumed at |3aL on the main frame l0. ,Thelink I4 opera-1 tively connects the other armor the. bell crank I3 to one arm of a bell crank lever'l5, also fulcrumed on the main frame I at |511. On

4 single cycle. Connected to the slide tube 26 is a pin-bearing 21 upon which is pivotally mounted one end of an operating link 28. This link 26 is connected to one end of a swinging arm 20 which pivots bodily about a pivot 30. Also pivoted on this pivot 30 is an arm 3| which carries a sliding block 32. Pivotally connected between the free end of the arm 29 and the block 32 is a 10. fulcrumed at IIb and is connected at its inner A,

the other arm of the lever I5 is pivoted a releasing member |51 provided with a rule-joint, as at :ISFwhich engage the upper portion of the bale `being formed and as .the latter moves in being formed, the star Wheel revolves. The star wheel is of a size such that its periphery will be equal .to thev length of the bale tobe formed. In the present illustration the star Wheel I6 is nonadjustable. On the shaft of lthe star wheel I0 is a short arm |61 which engages a hammer operating arm of the bell hammer I1. The hammer |1 4 is in position to ring the bell I8 as the arm |61 operates the hammer |1, once at the end of .each revolution of the starL wheel I6. The ringing of the bell |8 is the signal that the bale --being formed is of the*v proper size to be bound;

whereupon the operator moves the' handle of the lever I to his right to operate the bell crank lever I5 to cause its releasing member |51 to release the catch mem-ber 23 which in 'turn'releases the needle operating latch which will now be described.

The cross head on the plunger of the -usual and conventional type of baler, carries a pin 2| which registers with a latch 22 whichis released -bysuitable operating means, already described,

when the bale becomes of suicient size to require binding. A catch 23 with a detent 24' normally holds the latch 22 so that it is not in position to be caught by the pin 2|. However, when the bale is of suicient size to be bound, ,the releasing `member |51 is moved by the handle II, as already described. This member |51"en gages the end of the catch 23 and moves it against the spring 24HL to cause the detent 24 to disengage from the latch 22. The spring 25 now pulls the latch 22 to the position shown -in Fig. 2, ready to be engaged by the pin 2| at the end of its next stroke. f i

With the latch 22 in position for operation, as shown in Fig. 2, the cross head 20 on its next stroke causes its pin 2| to engage the slant face 228 forcing the latch 22 to one side andto 'then enter the operating slot 2-21, the sprng'25 continuously tending to force the latch 22 .to operative position. With the reversalr ofv movement, the catch 22 which is mountedon the f needle voperating slide tube 26 movesthelatter Afor a link 33. On one side of the sliding block 32 is a `cam roller 34 which engages a cam slot 36. It

is to be noted that the cam slot 36 is of irregular shape. During the iirst part of the stroke, the

" than during the latter part of the stroke.

As illustrated in Fig. 2, the fast moving part of the cam is .constructed on the arc of a circle. On the return stroke, the pin 2| engages an abutment 2611 which is rigidly attached to the slide tube 26, and returns the slide tube 26 to its initial position. The first portion of this return movement is fast `while the latter portion of the movement is relatively slow.

Pivot'ed to the free end of vthe swinging arm 3 I .is a link 31 which is connected to a needle operating frame 38. Perpendicular to the baler frame are guides 39 in which are mounted for sliding movement, the needles' |00. The frame 3,8 is connected to and moves the needles |00 in the guides 39. 1

There are two needles |00, one above the other to take care of the two wires with which the bales are bound. As the operation of the needles and their coacting devices isidentical, the operation of only one will be described in detail. Y

Referring to Fig. 4, the baling wire I0| is held from displacement in the guide`40 on the inside of the baling frame. y y v,

In- Fig. 4 is illustrated diagrammatically the path of the baling wire and the position ofone of the needles asit 'starts to contact the wire prior to forcing it through the baling space.

The wire I0| feeds out of a coil box 4|, through an eye 42a to a guide pulley 42 over which the Wire passes to pulleys v43, 44 mounted at suitable places on the main frame I0. From the pulley 44, the wire passes to a -pulley 45 located adjacent the guide 40, already described.

In the end of the needle |00 is a pulley |02 which forces the wire across the path of the baling mechanism. i

The needle |00 has a cut away portion |00a and a shoulder |001) for a purpose to be presently described. y

Below the pulley |02 is a rounded end portion |00c ofthe needle which is used to operate the cutter in a manner to be described. 1

On a supporting bracket |03 is mounted a guide |04 which guides the needle in the outer portion of its travel.l

A wire cutting member I 05. has an arm |05* for operating the gripping means and a short arm |051 which contacts and is operated by the neevdie end |000. The cutting member |05 is provided with another arm |05d which carries the cutting edge |056.

The cutting member |05,is;pivotally mounted at 05c on the side bracket |06 in such a manner that when it is moved pivotally, the cutting edge will coact with a stationary cutter member |01 mounted rigidly on thebracket |06. The outer end of the arm |05d is provided with a curved guide |058, tapered outwardly, which serves as a lifting means for the wire I0 I, to guide the same into a position for cutting.y

The rod |21 is connected at its .other end to a bell.. crank lever arm |28 which is. mounted on the lshaftlZS.- The shaft |29. is mountedpivoteally atthe bottomv ofthe baler frame .and carries atv the inner side, another arm |30.

' balies. operationhaving been started` in. the wel-Mmorm manner` l,with the Wires heldr bythe-holding.. members 12|, hay or other material is fed/into. the balingppress andthe. Well-,known nlungerelternately presses the ,hay or otherrnatee rial into the bale being formed and then Withdraws to permit more material to be put into the bale chamber in front thereof. As the formation of this bale continues, the Wire being secured by holding member l2 is pulled around the end of the bale nrst formed. When it is time to complete and tie one bale and start forming a new bale, the bell 8 located adjacent to the star wheel I6 rings, signalling the operator, who in turn pushes lever located on top of the baler. This trips catch 23 which allows the latch 22 to come into a position where it may be engaged by the pin 2| of the crosshead 20. As the crosshead 20v reverses its movement, the pin 2| and the latch 22 start the needle operating mechanism to drive the needle across the baling chamber, pushing the wire |0| into the cutting and gripping mechanism as shown in Fig. 3, whereby the wire |0| is caught by the teeth |09El and gripper |08. As the needles return, the wire |0| is cut by cutting members |e and |01 leaving one wire end gripped by the members |08 and |09 and one looped end wire free. As this operation takes place, the upright grippers |2| are released through mechanism |22 as already described, Fig. l. -At this" point of operation, the operator manually clamps the loose looped end wire by the holding members |2|. While this operation is `being done, the bale in the chamber is being formed and moved along the bale chamber, pushing the wire around the end of the bale the wire end being gripped by the gripper |09. After the operator manually clamps the wire |0| by holding member |2|, he now immediately, by pushing lever |05 releases the wire held by the gripper |09. This releases wire |0| forV completing the tie of the bale, which is performed manually. 'As the manual operation is `being carried out, a new bale is being formed.

1 The looped end of the Wire for the new bale, as already stated, is being held by holding member |2|. When the new bale is ready to be tied,

the operation of the manual lever causes thev pin'2l on the crosshead 20 to engage the latch opening 22"` and the needles again-bring in wire loopsfwhich are caught by the gripping devices |08, |09 and cut by the cutters |05@ and |01. On reaching its former position, the pin 2| 'overrides the opening 22b to position the latch` 22 for engagement by the detent 24. By the same action, the end of the catch 23 pivots the depending pivoted end I5b which latter is restored by the spring |5d. At this point, the detent 24 engages thelatch 22 to hold it retracted from operative position andthe cycle is complete.

As the movement of the latch 22 begins the forward movement of the needle operating slide tube 26, the link 28 begins to swing the arm 29. This causes the link 33.to pull on the sliding block 32. As the block'32 is mounted on the swinging arm 3| and since its movement is, by the cam roller 3-4, coniined to movement along the cam slot 36, movement of the block 32 takes place under this control.

It will be noted that the nrst part of the cam slot 36 which is followed by the cam roller is more nearly radial with relation to the pivot 30 of the swinging arm 3|, than the last part of the cam slot 36, which in the embodiment illustrated is constructed on an arc about pvot 30 as center. Due to this construction, for a given movement of the needle operating slide tube 26, there will be a less movement ofthe swinging arm 3| during the initial part of the stroke, vthan during the last part of the stroke, This initial slow movement,

pulls theneedle |00,V through the frame I8 and the. link:` 31, slowly to start the needle on its movement.' f l "One advantage ofthe slow starting movement is Ithat there isfless liability of breaking the wire as the roller pulley |02 of the needle |00 begins to force the wire through the baling space. As the pulley |02 with the needle |00 passes through the baling space,v the wire is fed from the usual wire coil box 4|. As the needle |00 at its outer end `|00c pushes against the arm |05b of the cutter |05, the cutter member |05 will be pivotally moved. Thisl movement causes the arm |05d of the cutter member to swing into the recess |00' of" the needle |00. This causes the wire to ride up onthe slope |05li adjacent the cutting edge |05e. Near the end of the movement of the arm |05d into the recess |00, the wire passes over the end of the slope |05g of the arm |05, the wire dropping 'into position between the cutting edge .|05e of the cutter |05, and the stationary cutter|01.

,.At-'the same time, the wire is assisted in its movement to a position between the two cutter members |05e, |01, by the cutter iinger |019. Also at the same time, the wire drops behind the grip lug` |08. Since the movement of the cutter |05 by the needle |00, also moves the gripper |09, through the link ||0, to open position, the wire drops in place to be gripped between the toothed edge |09it of the gripper |09 and the grip lug |08.

When the' needle begins to move back to its initial, inoperative position, by means of a reversalof movement of the parts 26, 21, 28, 29, 3|, 32, 33, and 34, the wire loopis left in place and as theshoulder |00b engages the arm |05d, the cutter memberV |05 reverses its movement. The spring ||2 operates to close the toothed edge 09a against the grip lug |08 with the result that the wire is rmly held in place. The guide finger |09 assists to prevent the wire |0| from escape from the gripping means until the wire is rmly held.

Continued movement of the needle toward inoperativelposition causes the cutting edges |05 and |01 to cut the wire immediately after it is gripped between thel gripping means |09a and |00. Since as the needle recedes, it leaves the wire loop", lthe cutting of the wire results in a short end gripped in the gripping means and a long end which is to' become a part of the wire for the new bale juststarted. As the needle operating slide tube 26 starts its return movement simultaneously causing the needle to recede, the lug |32 engages the detent |3|, turning the shaft |29, swingingthearm |28, pushing the rod |21, turning the -bell crank |25 to lift the releasing slide |22. -This,"through'the lugs |22b, turns the holding means`l2ll. At about this time, the operative has taken the wires in his hand so that when the releasing action takes place he can remove the -wires from ,the holding means.

VThe .completed bale `now moves through the baling frame with the new bale being formed in front of it as the old bale is` pushed toward the discharge end of the baler. One end of the wire at the rear of the bale having been released from the holding means |2|, the other end which is held by the-gripper |09, pulls the wire around the baleas'the` formation of the new bale progresses. Inftthis way 'there isa longer'free piece of wire on the gripper end than when the gripping took place.,` The arms |05'l are now manually engaged toA release the grippers |09. The ends of the wire will-fnow be free for tying with the ends released cutter to cut the wire adjacent the gripping means and the holding device to release its wire, all substantially at the same time. y
