GRAIN-BINDER.

SPECIFICATION forming part of Letters Patent No. 410,424, dated September 3, 1889.

Application led July l0, 1885. Serial No. 171,222. (No model.)

To all whom, t 77mg/ concern:

Be it known that l, SAMUEL D. MADDIN, a citizen of the United States, residing at Miainisburg, in the county of Montgomery and 5 State of Ohio, have invented certain new and useful Improvements in Grain-Binders, of which the following is a specification.

My invention consists in certain improvements in grain-binders, illustrated in the ac- Io companying drawings, and fully described hereinafter, and having for their objects to secure increased certainty in the binding operations, to simplify the construction of the operating devices, and generally increase the i 5 efficiency of the implement.

In the drawings, Figure l is a front elevation of a harvesting-machine, illustrating the general arrangement of the parts in connection with my improved binder, and drawn to 2o a smaller scale than the remaining views. Fig. 2 is a side view, in part section, showing the overhanging arm and parts supported thereby, and needle, compressor, and discharge-arms with some of their connections.

2 5 Figs. and l are views which together constitute a plan in part section illustrating part of the devices below the grain platform or table. Fig. 5 is a side elevation, in part seetion, of the knetter devices, needle, packers,

3o compressor, discharge-arms, and their supports and connections. Fig. G is a side view of the parts below the grain-table. Figs. 7 and S are detached views, in part section, illustrating the arrangement of the needle,

3 5 compressor, discharge-arms, and compressorsupports. Fig. 0 is a side view, in part section, of the stopping and starting device, compressor, and intermediate parts. Fig. l0 is an edge view of the parts shown in Fig. 9.

4o Fig. ll is a side view illustrating two of the gears of the machine. Fig. l2 is an edge view illustrating two of the gears of the machine. Fig. 13 is a plan view showing only so much of the machine as is necessary to 45 illustrate the relations of the binder-platform, the draft devices, the knotting devices, and the drivers seat. Fig. l-,L is a view of the same from the stubble side of the machine.

5o The base of the binder consists of a rectangular frame H and a cross-bar B, perforated for the passage of the axle B, upon which turn the wheels A A', supporting both the binder and one end of the platfor1nframe. Above the frame is supported a 5 5 table A4, one end of which extends over the outer wheel. Upon the frame are supported standards C O9, Fig. 3, near the inner side, and a standard Il near the outer side, and from the standard Il extend arms H2 and 6o HS Ilg.

The axle B constitutes the driving-shaft and carries a bevel gear-wheel H4, which gears with a pinion H5 upon the shaft l, which turns in suitable bearings beneath the 65 outer side of the frame H and at right angles to the axle. The shaft l also carries a sprocket-wheel l'lG and a hanged wheel H7, having an internal gear that engages with a pinion ll5 upon a crank-shaft Il, to the crank 7o of which is connected the pitman H10.

In the standards C C revolves a doublecrank shaft 2, upon which is secured a sprocket-wheel F5, from which a chain F6 passes to the Wheel H, and upon the shaft 2 turns freely 7 5 a pinion F7, which gears With the teeth of a wheel J, secured to a shaft 3, turning in bear ings supported by the frame and arranged parallel to the crank-shaft 2.

Each packer I is provided with a packer 8o arm It, and a downwardly-projecting arm 7111, and a rearwardly-projecting arm hm, the latter being adapted to receive the crank-pin of one of the cranks 22 of the shaft 2, while the end of each arm h is perforated for the 85 passage of the crank-pin of one of the cranks 55 of a double-crank shaft 5, that turns in bearings upon the cross-har B.

The needle L is secured to a shaft 9, roeking in bearings upon the standard Il and 9o having at the end a crank W5, and the ejectorarms K K are mounted upon a rock-shaft 8, supported in bearings in the arms H3, and has at the end a crank 7L. Reciprocating motion is imparted to the needleL from the rotating 9 5 shaft 3 through a crank-arm h2. Which is connected by a rod gT to the crank 7W, and the rocking motion of the shaft S, carrying the ejector-arms K, is effected from the revolution of a shaft 4, Fig. 6, a crank-arm h3 upon roc which is connected by a rod g to the crank h of the shaft 8. The ejector-shaft S, which,

with the needle-shaft 9, lies below the binderplatform, is parallel to said shaft and outside thereof, so that when the ejectors are down they lie over the needle-shaft. This enables me to use a shorter ejector-arm than is ordinarily employed, besides making a more compact arrangement of driving parts. Each ejector-arm is provided with an inwardly-extending guard-finger K12, preferably curved, as shown, which operates to catch any grain which may be thrown thereon by the packers and prevents its falling in between the ejectors and the binder-platform, as it otherwise might. The rotations of the shafts I and and 2 are continuous, so that the motion of the packer-arms is uninterrupted, the said motion being derived from the rotation of the crank-shaft 2.

It will be seen on examining the drawings, Fig. 5, that the cranks 22 of the shaft 2, instead of being upon the same plane are at an angle to each other; that the cranks 55 of the shaft 5 are of equal length with and arranged in the same manner as those of the shaft 2, and that the arms h and 7112 of the packers connect said cranks 22 and 55 together. I have found that by this means I am enabled to impart the requisite rotation to the shaft 5 from the shaft 2 through the medium of the packers while maintaining the proper relative arrangement of all the parts, this effect resulting from giving a slight lead to one of the cranks in respect to the other, so that as one of the packers is being drawn upward the strain upon the lower shaft draws downward the other packer, while any tendency of the lower arm of either packer to swing out of position is counteracted by the other packer connected 'with the same shaft, as will be readily understood from the fact that the cranks of the lower shaft are set at an angle, and as eachis turned part of arevolution by its connected packer the shaft is completely reversed. This continued movement avoids jerks and friction.

There are two compressor-arms M M, bctween which is clamped,by abolt h4, a curved supporting-arm M', having a slot y2, and a second bolt h5 passes through the arm M and through slots gain the hubs of the compressorarms, so that the latter may be set to any desired angle in respect to the arm M andthen clamped fixedly thereto. rlhe compressorarms are hung loosely at c'x, Fig. 7, to a link N, which extends into the slotted hub of the needle L and is hung therein loosely to the needle-shaft 9. The weight of the arms M M and link N would tend to cause these parts to swing downward upon the shaft 9, to carry the compressor-arms below the table, as in Fig. S. I therefore provide means for locking the parts in an elevated position during the time the grain is being forwarded or the y bundle is, packed.

Different locking means will suggest themselves to those familiar with the art; but I have shown those which I have found to be most effective, the same consisting of two toggle-links I2 I2, Figs. 7 and 8, the former or which is pivoted to the side of the link N and is provided with a flnger t", extendingbeyond the pivot, while the latter is pivoted to the link I2 and also to a stud i12 upon the frame H, and is provided with a lug t2, which when the arms M are elevated bears upon the link I2 and tends to keep the two in line with each other, so that they will serve as a brace to hold the parts in their upward position.

In connection with the movable support for the compressors just described I combine a trip which is independent of the needle, arranged to move said support and permit the compressors to be carried below the platform by gravity, and which trip I will now describe. The shaft 8 or ejector-arm K upon the same is provided with a finger 2, which extends over the finger fi', Figs. t and '7, which, when the ejector-arms are raised is brought into contact with the finger t', so as to swing the link I2 in the direction of its arrow, Fig. 7, carrying the links I2 I3 out of alignment when they will no longer serve as a brace, and the compressor-arms will fall below the table to the position shown in Fig. 8. The ejector-arms are thus made the means of unlocking the compressor-arms. The link N is provided with a finger c2, which is struck by the shank of the needle L as the latter nearly reaches its lower position, so that the link and the compressor-arms are then lifted by the further downward movement of the needle-arm until the links I2 I2 fall into alignment and lock the compressor-arms in place. It is of course necessary that t-he compressorarms shall be held in their elevated position and that the ejector-arms K and needle L shall be maintained in their lowest position until sufficient grain to form a sheave or gavel has been packed against the compressor-arm, after which the needle should rise, and after the bundle is bound the compressor-arms should fall and the ejector-arms should rise. I effect these movements from the mutilated gear-wheel J, which is constructed in a peculiar manner, which I will now describe. I

provide the periphery of the wheel J with gear-teeth J, which engage the teeth of the pinion F7 of the shaft 2, and I prolong a portion of said gear-teeth to form two series of longer gear-teeth j', a part of which latter are formed upon the periphery ys of an annular rib z', forming a part of the wheel J. The gear-teeth j', above the rib z', engage with gear-teeth formed upon the opposite side of a mutilated gear-wheel J2, which is mounted upon a shaft 4 and is provided between its teeth with curved delay-shoes k 7c', which engage the periphery of the rib e between the gear-teeth j. To permit the rotation of the mutilated gear-wheel J2 at the proper moment I provide the rib z at opposite sides of the teeth series j with recesses or notches z2 z2 24 z5, to receive the corners of the delay-shoes. The notched rib z', in connection with the IOO mutilated pinion J 2, serves as a means of imparting an intermittent rotation to the shaft 4. Thus as the wheel J is driven in the direction of its arrow by the rotation of the pinion F7, gearing with the short teeth j, the delay-surface 7c or k', restin g upon the face lg/S of the rib z', serves to lock the pinion J 2 and prevent its rotation until the notch of said rib is brought opposite the upper corner of said delay-surface k', and the rst tooth 7" against said corner,when the pinion J 2 will begin to rotate, and the teeth upon one side thereof will engage with the long teeth j' until the corner of the delay-surface enters the next succeeding notch z3, when the said delay-surface k will engage the face if', and will hold the pinion in place and prevent its rotation until the opposite corner of the delay-surface enters the next notch 54, after which the opposite teeth of the gearwheel will en gage with the next series of long teeth j', and the wheel rotated until the lower corner of the delay-surface t' enters the notch z5 and said surface is brought against the face f z/S, when the pinion J2 will again be locked and prevented from turning. As the pinion J 2 is connected to the shaft et, the latter is rotated intermittently, so as to first lift the ejector-arms 7;, (thereby unlocking and causing the depression of the compressor-arms, as before described,) then to hold the ejectorarms in position until the compressor-arms are again elevated, so that the discharge of the bundle is absolutely insured, and then to carry the ejector-arms back to their normal position below the table, these operations being all effected by a single pair of gears. The vibration of theneedle is of course dependent upon the rotation of the shaft 3, sothat it is necessary to arrest and start the motion of the wheel J upon said shaft, according as it is required to move and arrest the needle. This I effect by combining a clutch and a clutchoperating device with the loose pinion F7, which gears with the wheel J, and connecting the clutch-operating device with the compressor to be operated thereby. Any suitable friction or other clutch maybe employed, the kind of clutch determining in a large degree the style or kind of clutclroperating device to be used. I prefer, however, to use the clutch device illustrated in the drawings. To the pinion FT is pivoted an L-shaped dog K', against which bears a spring g, tending to throw the dog outward, so that an arm 7L thereof will strike an arm h of a doublearmed dog K2, pivoted to the wheel J, the other arm 7LT of the said dog being upon the opposite side of the wheel from the arm h6. The dog K' is provided with a projecting rib forming a shoulder s". (See Figs. 9 and l0.) A rod J pivoted at one end to the wheel J, passes through an opening in the arm h of the dog K2, and a spiral spring upon said rod is confined between a nut 'if and the arm h, and tends to throw the latter out in'to the path of the dog K', carried by the pinion F7,

which, when the wheel J is in the position shown in Fig. 9, will strike the said dog and cause it to swing in the direction of the arrow 3. Upon the inner face of the sprocket-wheel F5 are two lugs mm, which, when the dog K' is thrown inward by contact with the dog K2, pass beneath the shoulder z of the said dog K', so that the rotation of the sprocket-wheel and its shaft 2 has no effect upon the pinion FT; but when the dog K2 is swung in the dilrection of its arrow to carry the arm 7L away from the dog K', the latter will be thrown outward by its spring into the path of the lugs m, one of which will strike the end Q2 of the dog` and cause the pinion F7 to travel with the sprocket-wheel and to rotate thereby the wheel J in the direction of its arrow. The rotation of the wheel J is continued until the needle is carried down below the platform, the wheel making a complete revolution in lifting and depressing the needle, when the dog K' will again be brought in contact with the dog K2, and the former will be turned to throw the end c inward, so that the lug m will pass beneath the shoulder e, when the sprocket-wheel F5 will revolve, while the pinion FT remains stationary, as before dcscribed. It is desirable not only to lift the dog K' away from the lug m sufficiently to permit the latter to pass, but also to carry its projection or shoulder e wholly inside the path of said lug, as shownl in Fig. 9; otherwise the contact of the two would result in a disagreeable rattling noise. Ieifect this by extending the arm hs of the dog K' beyond the periphery of the pinion F7, so that the circle described by the end of said arm hs is greater than that described by the ends of the teeth of the pinion, whereby said arm travels faster than the periphery of the wheel J, which moves with the same circumferential speed as does the wheel FT, so that its movement is obstructed by contact with the end of the dog K2, although that is moving with the wheel J and in the same direction as the dog K', and is thus swung sufficiently upon being brought in contact with the end of the dog I7L to throw the shoulder e wholly within the path of the lug m. The dog K2 should remain in contact with the dog K', so as to keep the needle below the table until a sufficient quantity of grain has been packed against the arms M to form a bundle; and in order that the dog K2 may then be withdrawn to release the dog K' and permit the needle to riseI connect the compressor-arms and the dog K2 in such manner that the pressure upon said arms is made the means of moving` the dog. Different connections suitable for this purpose will occur to any skilled mechanic. Those which I have found 1o be lnost effective I will now describe, referring to Figs. 5, 9, and l0. A shaft l2,turnin g in bearings upon the fram c, carries at one end an arm m7, which extends over a lug s, projecting laterally from the arm h7 of the dog K2, and another arm m2, projecting from the shaft l2, is connected by a rodj2 IOO IIO

the compressor-arms is not sufficient to form a bundle of the desired size, the parts will remain in the position shown in Fig. 9, the dog K2 in Contact with t-he dog K but whenv the amount of grain is such that the action of the packer-arms forces it beyond a predetermined pressure against the arm M the latter will swing outward,the arm M connected thereto will be lifted and the lever L will be rocked in the direction of its arrow, Fig. 9, and will, through the rod g2, rock the shaft 12 and carry downward the arm 'm7 upon the lug s, so as to vibrate the dog K2 and carry its arm 7L away from the arm hs of the dog K,when the latter will be thrown into the path of the lugs m, whereby the pinion F7 will be rotated and the wheel .I will be carried with it.

rlhe degree of pressure necessary to swing the dog K2 so as to effect the above-described operation may be regulated by turning the nut i6, so as to compress, to a greater or less extent, the spring The adjustment of the said nut therefore maybe made the means of determining the density to which the bundles shall be packed. The size of the bundles may be regulated by adjusting the arm M in respect to the arms M, the nuts upon the bolt h5 being loosened to permit the compressorarms to be thrown outward or inward 4to any desired extent to vary the distance from the packers, after which the parts are again clamped xedly together.

To prevent the breaking of the parts should too great an amount of grain be thrown between the packers and the compressor, I arrange a spring-tension device, as the spring 16, Fig. 6, in such manner as to resist the outward movement of the compressor-arms and yetV permit them to yield under destructive pressure, and preferably having a certain amount of lost motion, for a purpose to be described. The spring 716 may be arranged in any suitable manner and may be of any suitable character. As shown, it is a coiled spring inclosin g a rod if", and arranged between a cross-plate is at the top of the rod and the lower cross-bar of a frame M2, sliding upon the rod, the upper en d of the frame being connected to the stud y upon the lever L, so that when the said lever is vibrated as the compressorarms swing outward the frame M2 will be raised against the pressure of the spring, but when the toggle-levers I2 Is are thrown out of line the compressor-arm can swing downward without acting upon the spring, inasmuch as the slotted arm M slides freelyv upon its pin jl. It is not desirable, however, that there should be any resistance to such an outward motion of the compressor-arms as is sufficient to rock the shaft 12 and release the Wheel J. I therefore provide for a limited movementof the frame M2 without compressing the spring by extending the rod i? through at stationary lug 719, Fig. 6, and providing the rod below the lug with an adjustable nutjl. This permits the rodi;7 and the spring to slide upward without resisting the movement of the lever L until the nutty'7 strikes the lower side of the lug t, after which any further motion of the lever L and the compressor-arms will result in the compression of the spring. It will be seen that the needle L and the ejector-arms K derive their movements from the rotation of the mutilated gear-wheel J, so that they work in absolute unison without the liability to derangement which is apt to ensue when these two parts derive their movement from widely-separated devices. By hanging the compressors to a link N, I am enabled to hold them firmly in position during the packing operation, but without. interl fering with their instant withdrawal when the bundle is to be discharged. This results partly from the fact that the pressure upon the compressor-arms has but little tendency to swing them downward, but. is mainly in line parallel with the table.

The knotter devices are supported at the end of an L-shaped arm O, overhanging the table, and having its standard nearest the horses connected between lugs 2l 2l, Fig. 3, so that the knetter devices shall be directly in line between the drivers seat CT and the horses, so that the driver, without withdrawing necessary attention from the animals, is enabled to maintain a constant watch upon the packing operations and instantly observe the breaking of the cord or any improper action of the parts. Heretofore the knetter, when above the table, has been generally rotated from a shaft carried by the overhanging arm or frame and driven by gears or otherwise from a shaft below the table. This arrangement has resulted in considerable friction and lost motion, and necessitates heavy gearing, all of which I avoid by transmitting the power through the medium of a lever M2, hung to the side of the arm O, and connected at the lower end by means of a rod MA1 to a crank 7a2 upon the end of the shaft G. (See Figs. 1, 2, 3, and 4.) The upper end of the lever M2 is connected by the rod 7&5 with the rack 7014, which rack may be a portion of a wheel or a reciprocating slide or bar, the back-and-forth movement of the rack in either case resulting in the operation of the knot-forming devices.

I do not in this application claim nor consider it necessary to describe in detail the peculiar knotforming devices which are shown in the drawings, since such devices form the subject-matter of another application, Serial No. 292,130, filed November 28, 1888, as a division of this case.

To prevent the turning of the shaft G,wl1ich is driven from the gear-wheel J by the rack 7a4 engaging therewith, when it should be at rest the mutilated pinion 7a4 has a delayshoe 7621 at one side with a curved face ai,

'an eye `yi to the needle.

which is brought opposite a plane face u8 of the wheel J after the rack passes from the pinion, and which prevents the turning of the pinion until the other end of the rack is brought in position to engage with the teeth of the pinion. I provide the delay-surface as of the wheel J at opposite sides of the gearsegment L5 with recesses 7cm to receive the corners of the delay-shoe R21, that the pinion 7J* may be rotated. The usual notched disk Q is arranged at the side of the knetter I), in position to permit the end of the needle to pass above the same, so as to lay the cord in one of its notches.

In order to secure a proper tension upon the cord,it is carried between a stationary jaw s2, Figs. S3 and G, upon a standard WV of the frame and a movable jaw s3 upon a lever V, pivoted at 231 to the standard XV, the two jaws being brought together by a spring s4, encircling' a screw-rod S5, which extends from the jaw through a hole in the jaw s?, and the spring s* is coniined between the outside of the jaw 32 and a nut s upon the rod.

In order to relieve the tension at properintervals, which occur twice in the formation of each bundle, I provide the shaft with two arms 3' SS, carrying lugs t* 255, which are brought in succession against the lower end of the lever V, and for a moment vibrate the lever to carry the jaw away from the jaw s2.

In order to prevent the drag upon the cord which sometimes occurs when it should be loose from resistance within the ball as the cord is being drawn therefrom, I use a cordextractor or take-up consisting of a lever WV', pivoted to the bracket IV, adjacent to the lever V, and provided with an eye g/G for the passage of the cord, which is conducted through an eye `y7 in a plate s through the eye y between the jaws, and thence through The lever lV is so arranged that its lower end will be struck by each of the lugs t1 'i5 while the jaws s2 .93 are closed and will swing back and drag from the ball sufficient cord to form the knot or supply the bundle, each lug as it escapes the end of the lever \V then striking the end of the lever V, so that the cord drawn out by the lever IV may pass freely to the needle, the lever IV swinging loosely until struck by the next lug.

It will be evidentthat while I have shown one form of knotter and knotting devices different mechanism may be employed for making and severing' the knot in connection with other of the improved devices and arrangement of devices which I have described, and that some of said improvements may be used separately from the others.

It will of course be evident that the knot-ter devices may be supported by any suitable frame extending over the platform of the binder instead of by the overhanging L- shaped arm O.

In different parts of myimproved machine I have used and described connections which, while effective to communicate motion between certain parts, may be replaced by other connecting devices. I therefore do not limit myself to those shown, as different forms will occur to anyone skilled in the art. For instance, the link N, carrying the loose compressor-arm, may be combined with any suitable removable support and may be pivoted adjacent to the shaft of the needle instead of hanging directly thereon, and the compressor may consist of one or two arms, and any suitable clamping device for connecting the compressor to the plate M adj ustably may be used. Other connections than those described may communicate movementI from the plate or arm h to the stopping and starting device. A friction-clutch may be used instead of the clutch described, and any suitable vibrating arm or cord-carrier may be used with like effect instead of the vibrating plate W.

I do not here claim the arrangement of binder, supporting-wheels, cutter-bar frame, and elevators shown in Fig. 1, as this constitut-es a separate application for Letters Patent, Serial No. 171,135, tiled July 9, 1885.

Vithout limiting myself to the precise construction and arrangement of parts shown, I claimp 1. The combination of the needle, the swinging link on the needle-shaft, the compressor adjustable on the link, a toggle-brace for supporting the compressor in its elevated position, a set-off mechanism operated by the accumulated gavel, and a positively-operated ejector having a projection which contacts with the said toggle-brace and breaks the same to permit the descent of the compressor, substantially as set forth.
