dog. Fig- 27 is a detail showing the knotter in operation.

In the drawings all like parts are referred to by the same numerals, of which 1 is the binding table or deck, on which th grain is delivered from the harvester in the usual manner.

2, Fig. 9. is the oscillating binding-arm.

3 is the binder-arm shaft.

4-is an ear formed on the hub of the bindershaft.

5 is an arm hinged at one end to the ear 4 the compressor 6.

7 is a link pivotally secured at one end to the arm 5 and at the other end to the free end of the crank-arm 8 on compressor-shaft 9, which is journaledin suitable bearings below the binding-platform, and has secured to its free end the crank 10, as shown in Figs. 3 and 4, and this crank has an arm or stop 90, which normally rests against the frame, as shown in Fig. 3.

11 is a connecting-rod pivotally secured at one end to the crank 10 and at the other end to the compressing-lever 12, which is fulcrumed at 13 to the frame, and is provided with a toe at its free end, and has pivotally secured at 1-1 the tension-rod 15, upon which is sleeved the compressor-spring 16, adjustably secured thereto by suitable nuts and washers 17.

18 is another lever fulcrumed on the same fulcrum 13 with the compressing-lever, but adapted to move independently thereof. This lever has three arms. The arm 19 bears a roller 20. The arm 21 terminatesin an eye 22, through which the tension rod 15 passes loosely and which serves as an abutment for the compressor-spring 16. Between the arms 19 and 21 is placed the curved guide-bar 23, on which there is a projecting top 24:, Fig. 21, against which the toe 35 is adapted to bear.

and having secured to it near the other end 25 is the third arm of this lever, and this has formed in its free end the eye 26, the rest 27, the abutment 28, and the stop 29.

30 is a movable stop pivotally secured to the eye 26 on the lever 18, and this stop carries at one end the roller 31, and to its heel it has hinged the tension-rod 32, which has sleeved upon it the spring 31, and projects through the abutment 28.

36 is a U-shaped frame rigidly secured to the binder-frame and for the purpose of supporting the knotter mechanism, as in the ordinary construction of binder. The overhanging arm of the U-shaped frame is hollow and supports in suitable bearings therein the operating-shaft 37 of the knotter mechanism. To the inner free end-of this shaft is secured the cam-wheel 60, and to its outer free end is secured the sprocket-wheel 38, which latter is provided with the cam 39, against the face of which the

rollers

31 and 20, heretofore described, bear.

40 is a sprocket-chain which passes around the sprocket-wheel 3S and around the little idler-sprocket 41, carried upon the arm 42, which is hinged upon the end of the packershaft 91, and is adjustably secured by the nut- 43 to the slotted guide-bracket 44. The lower portion of this sprocket-chain is guided on the under side of the curved guide-flange 45, which is formed 011 the arm 42, and the upper portion of the sprocket-chain passes around the under side of the sprocket-wheel 46, which is loosely sleeved upon the packer-shaft 91. This sprocket-pinion 46 forms part-of a clutch shown in Figs. 24, 25, and 26, of which the driving-head 47, forming one part, is fast on the packer-shaft, and carries two pins 48, either one of which is adapted to normally engage with the arm 49 of the dog 50, which latter is pivotally secured to the pin 51 ot the loose sprocket-pinion 46. This dog has an arm 52, which normally rides on the hub of the sprocketpi11ion, and also an arm 53, which projects outwardly and is adapted to strike in the operation of the machine the trippingarm 54 when the latter is in the position shown in Fig. 3, and thereby trip the clutchdog out of gear. This tripping-arm 54 is sleeved upon the binder-arm shatt3 (see Fig. 5) near the free end thereof, in proximity to the crank 55, so as to rest with its projecting flange 56 upon said crank, which is fast upon the binder-shaft. The tripping-arm has a yielding connection with the crank by means of the spring 57, and a connecting-rod 92, Fig. 3, pivotally connects it with the crank 93 of the tripping-shaft 04, which latter is secured in suitable bearings upon the binderplatform and carries the yielding arm 95, which is adjusted above the binding-platform in an inclined position, so as to be lifted up on its free end when the bundle has attained the proper size. The freeend of the crank 55 has hinged to it one end of the connectingrod 58, the other end of which engages with the wrist-pin 50 on the sprocket-wheel 38.

The knotter-operating cam-wheel 60 has formed around its periphery the annular delay-flange 64, and this is cutaway at three points, marked 61, 62, 63, in Fig. 10. The cut-away

portions

61 and 62 are formed by cutting the delay-flange away upon the outer periphery, and the cut-away portion 63 is formed by cutting away the inner periphery of the delay-flange. An oblique cam 61 is placed on the outer periphery of the delay flange between the cut-away

portions

61 and 62, and cogs 68 are placed upon the side of the cam-disk in proximity to and in relation with the cut-away portion 63 of the delayflange, and the cut-away end 65 of the delayflange is formed on an incline.

66 is a cam-groove formed in the body of the disk, and this cam-groove is partly concentric.

67 is a roller secured upon a wrist-pin on the wedge-shaped body formed between the eccentric portions of the cam-groove.

69 are ejector-arms carried by the shaft 37.

The knotter consists of the frame 70, which is provided with the hub 71, by means of which it is sleeved upon the shaft 37, and upon this hub is formed a gear-tooth 72.

'73 is the knottcr-shaft, upon which is se cured the knotter-pinion 74 and the head 75.

This knotter is of the usual bill shape and has a movable jaw 76, which moves parallel with the fixed jaw 77, formed integrally with the knotter-head. The knotter-shaft 73 is hollow, and through it passes a stem 06, to one end of which is secured the movable jaw '76 ot' the knotter-bill, and to the other end of which is secured an anti-friction roller 78, which bears on the cam 70, formed on the knotter-frame.

S0 is a spring pressure-foot bearing against the free end of the stem with the tension of the spring 81.

82 and 83 are contiguous flatdelaydiaces formed partly on the frame of the knotter and partly on the knotter-pinion, as shown.

84 is a support or bracket for supporting some of the operating parts of the knotter mechanism. This bracket is shown in Figs. 5 and 16. It has two ears S5 86, by means of which it is sleeved upon the hub 71 of the knotter-frame, and two legs 87 88, by means of which it is secured to the breast-plate S9, and thereby forms a rigid support. The lower end of the leg 87 of this bracket has integrally formed with it the stationary twinerest 97 and the twine-guide 100, Figs. 6 and 7, which by its roundingconfiguration guides the twine from the straight portion 101 oE-the needle-arm slot of the breast-plate into the lower curved end 102 thereof.

1033 is a short shaft journaled in suitable bearings formed in the support 84, and this shaft is provided upon its inner free end with the short crank 104, which carries the roller 105, which engages into the cam-groove 66 of the cam-wheel 60. Upon the shaft 103 is supported, as shown in Figs. 17 and 18, a hollow sleeve made in two parts 106 and 107, the

former being fast and the latter being loose upon said shaft, and the meeting edges of these two parts have projecting lugs or teeth in the manner of clutches to engage with each other, but allowing a limited-loose play to the part 107, and a coiled spring 108 sleeved upon them with one end made fast to one part and the other made fast to the other part. The loose part 107 is provided with a crank 10.), to which is pivotally selIO cured the rod 110, Figs. 5, 6, and 7, the other end of which is pivotally secured to the heel of the tucker 111. This tucker is fulcrumed on a pin 112 between the breast-plate and the foot 87 of the support 84, .as shown in Fig. 5, and has a free play forward from its normal position, (shown in Figs. 5, 6, and 7,) whereit rests against the stop 113.

From the shaft 103 is suspended the oscillating cord-holderframe (shown detached in Figs. 13, 14, and 15) by means of the

hangers

114 and 115, which have eyes 116 and 117 formed on their upper ends, through which the shaft 103 loosely passes. The hangers carry the annular grooved frame 118. in which is removably secured the rotary ring 119, provided upon its inner edge with a series of notches 120 and upon the upper side with a series of lugs 121. A shoe 122 embraces the inner edge of the rotary ring 119 by means of the groove 123 out therein, and this is secured to an arm 124, pivotally secured at 125 to the cordholder frame and provided with the spring 126, Fig. 14, the tension of which keeps the shoe in its engagement with the edge of the ring. The cord-holder is further provided with a knife 127, (shown in Fig. 15,) attached to the end of an arm 128, which is pivotally secured at 129 to the under side of the cordholder frame and carries the roller 130, which is struck periodically by the portion of the cam-wheel to force its cutting-edge against the cord to sever the same. The tension of the spring 131 tends to keep said arm in its normal position. The flange on the camwheel engages between the lugs on the rotary ring and locks the same until the cut-away portion of the wheel arrives at this point,

when the riugis unlocked. The inclined por-' tion 61 is then brought into contact with the lugs and forces the ring one step forward. The rotary ring 119 is prevented from turning backward by means of a locking-pawl 132, Fig. 15, which is adapted to engage with the lugs 121, thereby preventing any sudden jar from altering the position of the ring. The cord-holder is free to have an oscillating movement on the shaft 103, from which it is suspended, and this movement is brought about by means of a roller 133, carried by an adjustable extension 134 of the arm 115 and engaging into the cam-groove 66 of the camwheel.

To the support or bracket 84, before described, is pivotally secured a bell-crank 137, one arm of which carries a roller 135, Fig. 6, and a lug 136, the former of which engages into the cam-groove of the cam-wheel, while the latter is adapted to be engaged by the roller 67, carried by the cam wheel. The other arm of the bell-crank 137 has a notch 138, into which the cog-tooth 72 on the knotter-frame engages.

. In practice, the parts being constructed and arranged as described, it will be seen that the operation of the binding mechanism is derived from the packer-shaft 91, which, as in the usual practice, is provided with continu ous motion derived from the operating mechanism of the harvester in any suitable manneras, for instance, shown in the diagram Fig. 1, Where a sprocket-pinion 139 is secured upon the rear end of the packer-shaftand around which the sprocket-chain 140 passes, which conveys the motion from the operating parts of the harvester. The grain being delivered upon the binding-platform by the usual elevating devices, itis collected by the packers (which are of known construction and operation) against the compressor-arm. As the bundle is forming, the free end of the yielding arm 95 is gradually lifted up by the increasing gavel until by means of the connections described (which are adjustable for the purpose of regulating the size of the brim dle) the trip-arm 54 is lifted up sufficiently to release it from its engagement with the arm 53 of the dog of the trip-clutch. This movement throws the trip-clutch into gear and motion will be imparted immediately to the sprocket-chain 40 by means of the sprocketwheel 46. The sprocket-chain imparts motion to the sprocket-wheel 38, which thereupon begins to revolve the shaft 37, upon which it is fast, and also to convey the motion to the binder-arm shaft by means of the connectingrod 58 and crank 55. The sprocketwheel 38 makes one complete revolution, and this motion produces the necessary oscillation of the binder-shaft to carry the binder-arm sufficiently forward to lay the twine into the cord-holder and then back again to its normal position. This rearward oscillation carries the tripping-arm 54 back to its normal position, where it will trip the clutch again and arrest the further movement of the binder mechanism. The movement of the binder-arm also actuates the compressor-arm to compress the bundles,the normal position of the compressorarm being shown indotted lines in Fig. 9, while the full lines show the position it assumes while the binder-arm has finished its forward movement. In this position it is acted on by the tension of the compressor-spring 16, which is held between the two abutments 17 and 22. This abutment 22 is maintained by the lever 18, which, as described, carries the roller 20, and as long as this roller travels on the circular portion of the cam 39 (which it does until the bundle is tied) this, abutment remains stationary. The abutment 17 yields, however, and by means of the connection described the compressor-arm is permitted to yield to the force of compression on the bundle, and the abutment 17 will approach the abutment 22 untilthe pressure of the bundle is equal to the tension of the compressionspring. Thus by adjusting the abutment 17 the amount of yield of the compressor-arm under the force of compression on the bundle, as produced by the relative opposite movements of the bind er-arm and compressor, may be adjusted to any desired degree. In Fig. 4 the action of the compression on the compression-spring is illustrated by a diiferent position of the toe 35 from the normal position in Fig. As long as the roller 20 travels on the circular portion of the cam 39, the compression is maintained; but at the time the tying of the bundle is completed the roller 20 arrives at the end of the circular portion of the cam and is free to oscillate sufficiently to permit the compressor-arm to move out of the way below the binder-platform to permit the ejector to throw the bundle off. This withdrawal of the compressor-arm is brought about by the action of the movable stop 30, the spring 3% of which is under tension, owing to its roller 31 being forced to ride on the circular portion of the cam. (See Fig.4.) This tension causes the lever 18 to oscillate as soon as it is free to do so, and thereby to carry by means of the dilferent connections the compressor-arm out of the way until the roller 20 is again carried on to the circular portion of the cam 29 and the parts restored to their normal position, while the roller 31 of the movable stop drops onto the radial por-.

tion 1&0 ot the cam-guide, and thereby forms a stop, which prevents a retrograde movement of the parts and takes up the slack in the clutch.

The operation of .the knotter mechanism begins with the movement of the tucker, which is actuated by the roller 105, which is the first one to enter the eccentric portion of the groove in the cam-wheel 60. This movement causes the tucker to oscillate on its pivot, so as to cause its hook-shaped free end to engage upon the twine, tuck it into the twine-rest 97, so that it will be in proper position for the knotter-head to seize it. As shown in Fig. 9, the binder-arm prevents the tucker from withdrawing to its normal position before the binder-arm itself withdraws, and to permit the tucker to delay its reverse movement to the normal position I have constructed the yielding connection shown in Figs. 17, 18, and 19, which permits the roller 105 to return to its normal position under the action of the camgroove 66, while the tucker retreats to its normal position by the tension of the spring 108, as soon as the tucker is free to retire, when the binder-arm gets out of the way. The twine is carried by the head of the binderarm through the annular cord-holder, which has one of its notches 120 in proper position to receive the twine. The cam-wheel 60, engaging with its peripheral flange between two adjoining lugs on the rotary annular ring, keeps the same locked until the movement of said cam-wheel brings the cut-away portion between the two lugs, unlocks the ring, and permits the incline 61' to engage the next lug and to turn the ring one step, the lockingpawl arresting it in such position. By this movement the twine delivered by the binderarm into one of the notches is carried thereby until it is nipped by the shoe. Nowthe knotter begins to operate in the usual manner by the engagement of the cogs 68 on the cam-disk with the knotter-pinion 74, which is now free to revolve on account of the delayflange Get being cut away at 63. To provide the necessary slack in the twine for the formation of the loop, the cord-holder is now oscillated toward the knotter-head by means of the roller 133, which now enters the eccentric portion of the cam-groove in the cam-wheel. The second cut-away portion 62 on the peripheral flange of the cam-wheel is made to permit the knife 127 to keep out of the way of the twine until its roller 130 is struck by the corner 65 on the cam-wheel, which oscillates it sufficiently to cut the twine. The angular position of the twine as held by the cordholder helps to guide the twine into the jaw of theknotter, and the cord-holder is at itsnearest approach to the knotter-head at the time it delivers the twine into the jaw of the same. After the twine is cut the twine-holder is moved back to its normal position. The knotter-head makes two revolutions. At the first it forms the knot upon its head, and during its second revolution it strips the knot. This is accomplished by the roller 67 on the cam-wheel striking the lug 136 on the bellcrank 137', thereby causing the knotter-frame to oscillate and free itself from the knot. This movement is accomplished much quicker by means of the parts described than it would be accomplished by the roller 135 in following the eccentric portion of the camgroove, which movement would be too slow on account of the revolving motion of the knotter-head, which demands a quick movement just at the time when the jaws of the knotter-head are turned toward the bundle. However, the roller 135 returns the knotter again to its normal position. To permit the roller 67 on the cam-wheel to elfect the oscillation of the knotter-head, the cam-groove is partly cut away to permit the roller 135 to get temporarily outside the cam-groove.
