This invention consists, first, in having the platform of the machine so constructed and arranged that it may be raised or lowered to regulate the size of the bundle; second, in a compressor-bar arranged below the tying meolr anism and adapted to be raised by the binderarm to compress the bundle; third, in so constructing the grasper that it will hold auto matically any size of cord; fourth, in a stripping-hook for taking the loop off the knotter; fifth, in the peculiar construction of the knotter; sixth, in a trip and combined mechanism for stopping the packers at the instant the binding mechanism begins to operate; seventh, in the mechanism whereby the packers are set in motion and the binding mechanism stopped; lastly, in other constructions and arrangements of parts, as hereinafter fully described, and particularly pointed out in the claims.

In the accompanying drawings, A is the frame of the machine, to which the various parts of the invention are secured.

a is the main driving-shaft, on which are fixed one or more sprocket or other suitable wheels, at, by means of which and an endless chain or belt the binding mechanism may be actuated from the reaper driving mechanism. A driving-piniom'a, fixed 011 the main shaft meshes with a loose sliding gear-whee], a, on the packer-shaft a, and also witha gear-wheel, a turning looselyon the shaft a, which imparts motion to the binding mechanism. The gear-wheel a is provided on its rear or inner side with a clutch, a which engages at the proper time a clutch, a fixed on the packershaft a. The wheel a is pressed by a spring, a, into engagement with the clutch (d, and it is forced out of engagement therewith by one end of a lever, a, pivoted at its central part ISO ill

to the frame of the machine, the opposite end of which lever is actuated as hereinafter explained. The inner or rear end of the packershaft (0 is provided with two cranks, a a, on which the reciprocating packers a are journaled. The cranks are so arranged that they give an alternate movement to the packers. The packers at their upper ends are pro vided with slots,whicl1 engage the fixed pin or rod 1), whereby the movement of the lower ends of the packers is controlled in such a manner that they engage the graiudelivered from the harvester, move it toward the binder mechanism, and then draw upward out of contact with it. The pin bhas one of its ends fixed to the frame of the machine.

I) is a standard pivoted 011 the rod I) between the upper ends of the packers, and it has made fast to it one end of an arm, I)", on the other end of which are pivoted, near their upper ends, the outer compressor-arms, 1)", against which the grain is pressed by the packers, said arm being bent in to meet the arm I! at their common pivotal point. The arm If passes through a sleeve, 1/, fixed on one end of a lever, b, which has its other end pivoted'on a rock-shaft, c. The lever b" is lifted by a cam, hereinafter described, and thereby the compressors I) are raised, so that the bound bundle can be discharged at the outer side of the platform. The lower ends of the compressors I) extend down nearly to the platform, and are adapted to yield to a certain degree to the pressure of the grain by means of the spring Z) on the rod 1)", which is pivoted to an upward extension of their united upper ends. Said spring bears against a nut on the bar I), and is compressed against a standard rising vertically from the arm 11-.

The rock-shaft C has fixed upon it two caniarms, a. 0, located in such a position that the compressor-arms b" may come in contact therewith and move them outwardly, and thus rock the shaft 0.

On the outer or forward end of the rockshaft 0 there is fixed a bent trip-lever, 6-, one arm of which is arranged to come in contact with a pivoted pawl, d, hereinafterdescribed, while its other arm is placed on a rod, c,which has its lower end fixed to the lever d", hereinafter described. Around this rod 0" is coiled a spring, 0*, which acts against the arm of the trip-lever c and thus raises the triplever out of engagement and restores the rockshaft c to its normal position.

The principal parts of the binding mechanism are operated by the shaft a, journaled in the upper part of the supporting-frame A. Near the outer or forward end of said shaft, inside of the gear-whecl (1 there is fixed a disk, (I, on the outer face of which is pivoted the U- shaped pawl d, which is controlled by a spring, d", fixed to the rim of said disk. The rim of the disk has formed in it a cam-notch, d", having one of its edges properly inclined, into which notch the inner end of the clutch-shifting lever c" drops. The opposite or outer end of said lever is extended to and bears against the rear side of the gear-wheel a, as 11eretofore described.

\Vhen the inner end of the lever a is forced out of the notch d, the wheel a will be forced against the spring a" and be disengaged from the clutch a on the packer-shaft. Vhen the disk at rotates and brings the cam-notch opposite the inner end of the lever a, the end of the lever enters the notch, and the spring a forces the gearwheel u back into engagement with the clutch u, and the packers are set in motion.

The large'geanwhecl (0 has three pins, d, arranged about equidistantl y around its center, and projecting at right angles inward toward the disk (2. One or the'other of these pins engages the inner edge of the pawl d, which latter, being pressed down on the pins by the spring d, locks the wheel a and the disk d together. At the proper moment the triplever 0- is brought down, and the outer end of the pawl d, as the disk (I rotates, comes in contact with said trip-lever, and the pawl is thereby forced outward against the spring d and is dis engaged from the pin (1*, thus unlocking the disk d from the wheel a. \Vhen the wheel a and disk d are locked together, the shaft a will revolve, and when they are unlocked the shaft will remain stationary, while the wheel a, which is mounted loosely thereon, will continue to rotate. The unlocking of the shaft and disk takes place wheneverthe compressorarms Z)" rock the shaft 0 by depressing the camarmsc c, for as the lever 0* is fixed on the end of said shaft its arm toward the pawl will be depressed, and will bear upon and move the end of the pawl outward, as above described.

It will be seen that the described mechanism is so arranged that the shafts (Wand aare alternately engaged and disengaged from the driving-shaft, so that when the packers are in motion the binding mechanism is stationary, and when the latter is in operation the former are at rest.

A rock-shaft, (Z is journaled in the frame below the outer or delivery side of the binderplatform, and carries on its inner or rear end the binder-arm 7r, hereinafter described. Said rock-shaft has fixed on its outer or forward end a segment-pinion, d, which is engaged by a segment-rack, (F, on the lower end of the rocking arm (1", which is pivoted on the frame A. The arm at is also provided with a smooth segment or delaysurface, (1. The upper end of the rocking arm is provided with a slot, (1 in which is placed a sliding bearing, (1, through which passes the wristpin 0 of the crank 0", fixed to the outer or forward end of the binder-shaft a. The gearwheel alis situated between the crank c and the disk (1. \Vhen the shaft a rotates, the crank c" rocks the lever or arm (I on its pivoted center, and thereby the shaft (P is rocked so as to raise and lower the binder-arm.

Near the inner or rear end of the shaft a is fixed a cam and gear wheel, 0. In the forward edge of the rim of the wheel is formed a notch, e, opposite which stands a lug, eflwhich is so formed and placed as to make with the notch e a curved cam-groove, 6, between it and the rim of the wheel. On the opposite side of the rim of the wheel are two cogs or teeth, 6, which engage at the proper time with the knotter-pinion. of the wheel 0 is formed a cam-groove, 6, into which one end of a pin, 1)", fixed transversely through the arm If enters. Another wh'eel, e, is fixed on the shaft (6 to the rear of and near the wheel 0. The wheel 6 has a part of the forward edge of its rim formed into a rack, c facing the wheel c, and is provided with a cam-groove, a similar and opposite to the cam-groove 0" in the wheel 6, into which camgroove c the opposite end of the pin b" enters. The arm I;' is raised by the pin Z) and the cam-grooves e and a and by this means the c0n'ipressor-arms are lifted up from the platform, so as to permit the bundles to be discharged below them. The segment-rack e and the cogs c consecutively engage the knot ter-pinion. The segment-rack rotates said pinion in one direction, and upon disengaging from it the teeth 6" give said pinion a partial reverse rotation.

A dischargingari'n or kicker, f, is fixed on the inner or rear end of the shaft a, and is so placed thereon that it throws the bundle after it has been bound from the platform.

The platform 9 is made in two sections, 9 and The inner section, 9, is fixed, and the grain is discharged upon it from the reaper. The outer section, 57*, is hinged to the outer edgeof the section and may be raised or lowered,so as to vary the space between it and the curved brcastplate g, according to the amount of grain which it is desirable to make into a bundle. By raising the section y the binder-arm has to move the presser-arm 9', now to be described, through a shorter distance. transverse slot, 9, is formed in the platform running across both sections and situated vertically below the knotting mech anism. A longitudinally slotted vibrating pressenbar, g, swings in the slot g, and has its inner end hinged to the lower surface of the fixed section g of the platform, while its outer end is free, so that it can be raised to compress the bundle between it and the lower surface of the fixed breast-plateg. The outer end of the presser-bar has a plate extending outward and resting upon the upper surface of the section 9", thus keeping the presser-bar from falling through the slot 9. The presserbar is raised by the binder-arm, which passes through its slot, a pin, '1', which passes through said arm, and is hereinafter more fully described, coming in contact with the lower edges of the presser-bar.

The section of the platform may be set at any desired inclination by means of adjustable supports 5 held in the framing below the platform.

The t-wi nebox 71 is mounted upon a standard,

011 the inner or rear surface drawn.

tension to the cord.

h, secured at or near one of the outer corners .Of the platform, so as to be entirely out of the Way of the grain as the latter is carried through the binder. Said twine-box is provided with a glass front, if. The box is made water-proof, so that the ball of twine will be kept perfectly dry. Through the bottom of the box a suit able hole is made, through which the twine is A tension-pulley, h, is placed below the twine-box, and held in position by a black et, h, having a pin on which the pulley rotates. A coiled spring surrounds the pin, and bears against the bracket h at one end and against the side of the pulley at the other, and the friction caused by the spring retards the rotation of the pulley and gives the necessary The tension is regulated by the nut on the end of the pin.

A guidepulley is jonrnaled in a suitable braciket fixed near the bottom of the standard t.

The binder-arm is is composed of the two similar and parallel bars, 7.1 l.", placed side by side, and secured firmly together at suitable points. The bars at their united outer ends are formed into a solid point, k for piercing the grain. Small anti-friction guide-rollers it,

If, Ir, and Z' are pivoted between the bars Ir 1.", over which rollers the cord passes on its way from the twine-box to the holding and knotting mechanisms. The bars 7.7 I," of the binder-arm have made in one piece therewith V The roller 7." is pivoted between the bars I."

7.", near the point of the binder-arm, the roller It a short distance above the elbow 7: and the roller at a proper point between the rollers 1. and 7?.

By the described construction and arrangement the binder-arm may be made very light and strong, and the wear and tear avoided which would result if the arm were made of one piece of metal heavy enough to give the requisite strength.

An arm or finger, it, is pivoted between the side bars of the binder-arm on a pin, i, the ends of which project outward on opposite sides of the binder-arm to raise the presserbar-g, hereinbefore described. The end 'i of this fingeris made slightly hooked, and in the operation of the machine it is thrown outward, as hereinafter described, and presses the cord justbelow the knotter, for the purpose hereinafter described.

Vhen the binder-arm is swung down below the platform, and while the grain is being packed to form a bnndle,the finger k is drawn in between the bars of said arm out of the way. It is turned outward by the following means: A slotted sliding bar, A, has one end pivoted to the end of the finger and its other end longitudinally slotted at i". The binder-arm rockshaft (1 passes through the slot and supports the bar It. The said bar is provided with a pin, i", which enters an eccentric slot, 2', formed in a lug, i, fixed on the end of the sleeve or bearing 5 which supports the binder-arm rock-shaft at. As the binder arm is thrown up, the cam-slot acts through the pin i to slide outward the bar It, which turns out from the binder-arm the free end i of the finger It.

When the binder-arm is thrown up in the act of binding a bundle, the lever d swings outward, as shown in dotted lines in Fig. 8, and the delay-segment d slides on the ends of the two inner cogs of the segment-pinion d, thus allowing the crank c to continue its revolution without further moving the binderarm rock-shaft, but holding the said shaft and binder-arm firmly and steadily in place while the knotter is-in operation and the knot is be ing tied.

The grasper m, for holding the end of the cord,is composed of a hook,m, pivoted between two parallel plates, m and m, lying close together and supported by the parallel rods m m*,which pass through said plates. A suitable opening, of, is made in the plate m and a notch similar to the lower part of said open ing is made in the upper edge ofthe plate of, the opening and notch being for the passage ofthe point of the binder-arm. Spiral springs m surround the rods m, and are suitably held so as to bear against the plates m? and m to press them together, while permitting them to yield slightly to different thicknesses of cord. The inner plate, on", is extended up-' ward, as shown, and has pivoted to it the shank of the hook m. Said shank extends upward from its pivotal connection, and has standing at right angles from its inner surface the pin m, the projecting end of which bears against the side of the rim of the wheel 6, and is drawn into the cam-groove e by the lug e. The rim of said wheel bearing against said pin m retains 'the' hook m in the position shown in full lines in Fig. 17. When the pin passes through the cam-groove 6 the hook on is moved across the opening m, as shown in dottedlines, and then immediately returned to its first position. A knife, m is placed on the inner plate, m, on the side adjacent to the hook on. The hook and hook-bar bear against the side of the knife, and are held against it by the pressure of the springs m. The knotter a is supported on a hollow shaft, a, set in a nearly-vertical position and standing close to the track of the binder-arm. The hollow shaft on has on its upper end the pinion n, situated between the lower portions of the wheels 6 and e, and actuated by one or the other at the proper time. The pinion is rotated in its direct movement by the segmental rack e on the wheel 6, and is immediately afterward partly rotated in the opposite direction by the two teeth 0 on the wheel a. The inner shaft, it", passes through the hollow shaft a, extends above the pinion 01 and is surrounded above said pinion by a coiled spring, a", held in place by a suitable nut, as shown. The two shafts are properly supported in a depending sleeve bearing, a". The spring 02' allows a certain amount of vertical motion to the shaft or, and presses the two knotter-hooks together with a yielding pressure, so as to properly hold cord of varying thickness.

The knotter consists of two parts-a horizontal hook-jaw, 0, fixed on the end of the hollow shaft n, and a plate, 0, fixed to the end of the inner shaft, n, and having on one side the hook-jaw 0*, to co-operate with the hook-jaw 0. Between these two jaws 0 and 0 the cord is grasped during the operation of tying the knot. On the other side of the plate 0' is formed the wing 0", which curves upward in the form shown in Fig. 3, so as to slip over the cord and cause it to pass under the knotter. The plate 0' is limited in its movement on the hook-jaw 0 by the curved slot 0, formed in the plate concentric with its center of motion, and the pin 0 projecting downward from the jaw 0 through said slot. The plate and jaw move on each other to allow the jaws o and o to open and grasp the binding-cord at the proper time. A spring, a, is attached at one end to the frame of the machine, and has its other or free end so situated as to come in contact with a lug, 0 on the upper edge of the wing 0 when the knotter has been rotated by the segment-rack e and the loop has been formed round thejaws. This contact detains the jaw 0, while the other jaw continues its motion for a short distance, thus separating the jaws 0 and 0 so that they may receive the ends of the cord outside of the loop which has been formed around the jaws by the rotation. At the end of this rotation the lug 0 slips over the spring 0. The knotter is then given a partial rotation by the teeth on the wheel 6 engaging the knotter-pinion. The lug 0 again comes in contact with the spring 0, and the jaws are thus closed upon the cord. Vhen the spring 0 slips over the lug o, it makes a ringing sound, indicating that the tying operation is nearlypover and that the cord around the bundle just formed is about to be separated from the ball of twine, the cutting mechanism being arranged to act as soon as the knotter-jaws have grasped the cord.

An oscillating bar, 8, is pivoted at to the frame in such a position that its inner or forward arm swings just below the knotter. Its outer or rear arm, 8, is bent outward, and in its normal position lies in a line slightly inclined to the direction of the movement of the grain through the machine and across the path of the rear compressor-arm, I). A stripper-hook, s, is pivoted to the inner end of the bar 8, and is pressed by spring 8 against the small pin 8. The spring allows the hook to yield to pass IIO over the cord, so that it can engage the cord on its return movement and strip off the loop from the knotter-jaws. I

The arm 8 of the bar 8 is so constructed and situatedthat it will be engaged and pressed to the rear by the rear compressor-arm, I), which will cause the hook s to swing slightly andpassoverthecord. As thedischarging-arm f moves outward to discharge the bundle off the platform, it strikes the rear edge of the arm 8, and returns the bars to its first position. In this movement the hook s seizes the cord and strips the loop from the knotter -jaws over the ends of the cord held in the jaws, and completes the knot. At the same time the cutter severs the cord. The bar 8 lies just outside of the path of the binder-arm, and when the latter ascends the finger It brings the two portions of the cord which passes around the bundle together, and holds them against the lower surface of said bar 3 while the tying mechanism is in action.

The operation of the machine is as follows: The grain from the reaper is fed onto the section 9 of the platform, and is conveyed bythe packers under the breast-plate and against the cord o and the compressor-arms I). These compressor-arms yield to the pressure of the grain, and when the proper quantity to form a bundle has accumulated they will be forced back sufficiently tobearagainst the cam-levers c c, and thereby turn the rock shaft 0 and the attached trip-lever c". The trip-lever will thus be lifted from the pawl d, so that the latter will drop and be engaged by one of the pins (1 on the wheel a thus putting the disk (I, and consequently the shaft a and the binding mechanism, in motion. The size of the bundle is regulated by the position of the hinged platform g Vhen it is desired to make the bundles smaller, the platform is raised. This makesa smaller passage between it and the breast-plate, and it is obvious that a less quantity of grain will cause the necessary pressure to operate the tripping mechanism. As soon as the disk (Z begins to move, the inclined side of the notch d" forces out the end of the clutch-shifting lever a thus forcing out the pinion a, and disengaging the clutches a and a The packer-shaft a and packers a are thus brought to rest. In this manner the packer mechanism and the binder mechanism are alternately in operation, the one being always in gear when the other is out of gear. The binder-arm being in its lowest position, the cord u runs from the twinebox around the tension-pulley 7i, thence around the guidepulley at the bottom of the standard h, thence over the guide-roller w and over the roller it, both the latter being fixed to the binder-arm nearits pivotal point. From the roller k the cord passes around the rollers k and k", and over the roller 73 in the point of the binderarm. It then passes upward over the edge of the bar 8 and over the knotter-hooks, whence it passes to the grasper, where its end is held between the hook in and the platem The tension of the cord as it runs from the ball in the twine-box is regulated by the tension-roller h. \Vhen sufficient grain has been accumulated to form a bundle, the binder mechanism is set in motion, the binder-arm is raised, its point dividing the grain, and carries the cord around the bundle and up over the knotter-jaws and to the grasper. The finger k presses the cord at a point between the gavel and the bar .9. The cord is thus drawn taut and held so that it will pass under the wing o of the knotter. The k notter revolves a little more than a complete rotation, forming a loop around the jaws. Just before the knotter completes its revolution the jaws are opened by the lug 0 coming in contact with the spring 0". The cords leading to the holder and point of the binder-arm then enter between saidjaws. Just before the completion of the forward movement the lug 0 passes beyond the end of the spring 0. The knotter is then turned backby the teeth e", and the jaws are closed by the spring 0, and hold the cords between them. The holding-hook m is now operated. It catches the cord and severs it against the knife m and holds the end running to the binderarm between it and the plate or, while the binder-arm returns -to its lowest position, and the two ends 22 of the out cord are freed. The loop o around the jaws is now drawn off the jaws and over the ends 0 by means of the stripper-hook 8*, thus completing the knot. The compressor-arms b are lifted, and the discharger f revolves and pushes the bound bundle off the platform, drawing the ends of the cord from the knotter-jaws. The binder-arm is now thrown down. The rod 0 and spring 0* throw out the tripping-lever into the path of the pawl d, which pawl, coming into contact with said lever, is raised out of contact with the pins (1", and the binding mechanism is thrown out of gear and comes to rest. At the same time the end of the clutch-shifting lever a drops into the notch d, and the spring a" throws the pinion a into engagement with the clutch a and the shaft (0, and the packers are set in motion and the operation is repeated.
