SPECIFICATION forming part of Letters Patent No. 402,025, dated .April 23, 1889.

Application led May 2,1887. Serial No. 236,852. (No model.) Patented in Canada March 3, 1888, No. 28,617.

To all whom it may concern:

, -Be it known thatI, SAMUEL DOMINICK MAD- DIN, a citizen .of the United States, residing in the town of Sarnia, in the county of Lambton,.Canada, have invented certain new and useful Improvements in Harvesters, (for which a patent hasbeen granted in Canada, No. 28,617, and dated March 3, 1838,) of which the following is a specification.

This invention relates to grain-binders; and it consists in certain improvements thereon, as illustrated in the accompanying drawings and fully hereinafter set forth.`

My invention has for its object, among other things, to simplify the construction of the operating devices, to secure increased certainty in the binding operations, and generally increase the efficiency of the machine.

In the drawings, Figure 1 illustrates by a side elevation the binder side of a harvester embodying the present improvements. Fig. 2 is a rear elevation thereof enlarged, showing particularly the grain-binder and a portion of the frame supporting the grain-elevating aprons, the knetter and its supportingframe being removed. Fig. 3 is a sectional elevation of the grain-binder, taken on the lines a: of Figs. 1 and 4, looking from the front of the machine. Fig. 4 is a plan View of the grain-binder, the platform being removed for perspicuitys sake. Fig. 4fL is a perspective view of parts of the binder-frame on a somewhat smaller scale than the other iigures.v Fig. 5 is a plan View of the complete harvester. Fig. 6 is a rear elevation of the harvester portion proper and the frame supporting the elevating-aprons. Fig. 7 is a detail sectional elevation of the elevator-aprons.

Fig. 8 is a perspective view of the wheel by knotter, taken on the linea of Fig. 1 3, showing also a portion of the needle. Fig. 12 is a 5o horizontal sectional elevation-of the notched disk and holder-shoe. Fig. 13 is a side elevation of the knotter, its guard-plate being shown in section. Fig. 14 is a perspective View of the oscillating operating-wheel of the knetter, 5 5 and Fig. 15 is a plan View of the knetter. The binder portion of the machine is supported by two wheels, A A, both connected to drive the operative parts of the binder and turning with a transverse axle, B, and the lat- 6o ter supports the frame of the binder, consisting of a sleeve, C, mounted upon the axle, an angle-bar, D, extending across and secured to the sleeve, a strip or bar, E, bent toform a' horizontal portion, 2, extending over the binder-platform, and two vertical arms, 3 3, which extend past the ends of the platform,to which they are secured, thereby supporting and steadying the saine, the ends of the arms 3 being bolted to the angle-bar D', and a bar or 7o plate; F, of a U shape, is also provided, one

arm, 94, being secured to the sleeve C and extending parallel to the bar D, while the remaining portion curves up parallel to the strip or bar E and overhangs the platform G, and supports at its end the knob-forming appliances hereinafter described.

The drivers seat H is secured to a support, E', extending from the rear end of the bar D, and the pole, which is pivoted to the frame, 8o projects forward from the opposite end of the frame, in a manner not necessary to here set forth.

The various operating parts of the binder are driven from a bevel-wheel, I, turningwith the axle, said axle being driven through the medium of a pawl and ratchet, which permit the machine to be moved backward without driving the bevel-wheel. The platform G is supported between and aboveithe wheels by 9o brackets extending to and forming parts of the frame, and in one of Athese brackets J, Fig. 2, just below the platform, turns a shaft,

4, upon which swings the hub of theV needle K, of the usual construction, and en said shaft is secured a mutilated cog-wheel, v5 t 'o the side of which are fastened the compressorarm L and the dischage arm or ejector L.

In another bracket, J', secured to the anglebar D turns a double-crank shaft, (i, the crank pins of which extend through bearings in the packers M M', the packer M having two horns, 7 8, while the packer M' has a single horn, 7, and the outer end of the packer M, Fig. '3, is connected to a link, 9, pivoted at its lower end to the frame, while the outer end of the packer M' is connected to a link, 10, pendent from the rear end of the shaft et. The bar D supports another bracket, K', in which turns a shaft, 12, having a crank-arm, 13, for operating a supplemental packer-arm, M2, set farther front than the usual packer-arms, in order to catch grain falling at the front of the platform, and the outer end of the packerarm M2 is suspended from a link, 14, jointed to a stud at the lower side of the platform.

The general operations of the parts above described are similar to those in ordinary well-known machines-that is, the compressor-arm L in the position Fig. 2 receives the grain which 'is packed against it as delivered to the platform by the operation of the packer-arms M M' M2 until the needle passes the cord around the bundle and the cord is tied and cut, after which the compressorarm descends and the bundle is knocked off by the discharge-arm or ejector L', and the con'lpressor-arm then brought to its first position. These operations yneed not be further explained, and I will now describe what constitutes the main features of my invention-that is, the contrivances for imparting motion to the various operating parts. Before doing this, however, I will refer to the fact that the compressor, instead of vibrating from its upper to its lower position, as usual, moves around the axis of the shaft 4 as a center, in the direction of the arrow, Fig. 2, thus traveling in a circle, its movement being arrested as soon as it assumes a position t0 receive the grain packed against it by the packers. In like manner the discharge-arm L revolves instead of reciprocating, following the path of the compressor, and preferably connected thereto, as before described. By this mode of operation I not only simplify the character of the actuating devices and operate the compressor and discharge arm by a single action, but I also avoid the accidental catching of the finished bundle, which is apt to result occasionally when the compressorarm, having a vibrating motion, returns toits position. Moreover, should the ejector or discharge-arm fail to completely throw oif the bundle, the compressor itself, traveling outwardly, will act as a discharger to effect the desired result.

The reciprocating movements of the necdle and the intermittent rotary movements of the compressor and discharge-arm, and also the movements of the knotter devices, are all effected from the rotation of a single wheel, N, located below the binder-platform in a plane by the side of the needle. This wheel N turns upon a shaft, 1S, extending through the bracket J, and is provided atjthe outer side, Fig. 3, with a pin, 19, connected by alink, 20, with the needle at a point but a short distance from the fulcrum thereof, so that each revolution of the wheel N results in a complete vibration back and forth of the needle, which is thus operated directly from the said wheel, and the power is applied to the needle between its fulcrum and its point, thereby avoiding the strain which results from applying the power to the shaft upon which the needle is mounted, as heretofore has generally been done.

The knotter devices carried by the overhanging portion of the arm or bar F are all operated by the reciprocation of a rod, 21, Fig. 1, connected to a lever, P, pivoted to the arm F near its center, and this lever is vibrated by the movement of acrank-wheeLQ, the crank-pin of which is connected to a rod, 22, extending to the lower end of the lever I). The wheel Q revolves only during the formation of the knot and cutting of the cord, and is then held stationary during the other operation of the machine, for which purpose it is formed as a mutilated cog-wheel provided with teeth around part of its periphery adapted to a rack, 23, at one side of the wheel N, and with a delay-shoe,.2et, which, during the time that the knotting devices are to remain stationary, is in contact with a plain face, 25, upon the side of the said wheel N. A similar mutilated wheel, 5, before described, operates in conjunction with a rack, 26,and a plain face, 27, upon the periphery of the wheel N, to impart the desired movements to the compressor and ejector arms and to lock them in position when the grain has been packed. The wheel Q lies in a plane at right angles to that in which the wheel N lies, so that I obtain a reciprocating motion in a direction parallel with the shafts of the other main operative parts of the machine for the reciprocating knotteroperating devices.

It will be observed that the'wheel S ,which drives the wheel N, is smaller than wheel N, so that the rack 23 and the face 25 are outside the periphery of wheel S, which permits the mutilated gear Q. and the link 22, operated thereby, to pass wheel S without interference therefrom or from the chain' driving it. By thus connecting'lthe compressor and ejector arms directly to the wheel or pinion 5, gearing directly with the wheel N, and by operating the knotting devices directly from the pinion or wheel Q, also operated directly by the wheel N, I greatly simplify the construction of the machine, reduce the number of its parts, decrease its weight, and avoid the friction which results in ordinary machines where there are numerous intermediate connecting devices, while, owing to the direct connections, the lost motion is much less than usual. Further, the

construction described enables me, in a machine of the character described, to mount the mechanism which drives the needle, compressor, packers, &c., low down and near the IOO ITO

main axle ofthe machine, while the knotting mechanism, which is mounted above the as the compressor-arm and the needle and they knotter devices must all remain at rest while the grain is being packed against the' compressor-arm. I therefore provide means whereby the wheel Nmay be driven from a continuously-moving chain, R, which operates the other parts of the machine, the movements of which are not to `be interrupted. It

is also important to start the wheel Ninv operation as soon as but not before the requisite amount of grain has been brought between the packers and the compressor-arm to form a bundle of the desired size. fect this intermittent operation of the wheel ,N from a continuously-moving chain, and to pending upon the pressure of the grain against the compressor-arm and trip for its position and serving to lock the sprocketfwheel S and the wheel N together when in one position and in another position to unlock them, so

n Vthat the sprocket-wheel can continue its revolution without imparting movement to the wheelN.V

Different intermediate locking devices may `be employed, as well as different means for n ladjusting them according1 to the pressure of the grain against the trip-arm. In the draw-` ings',.Figs. 3 and 9, the wheel S is shown as recessed at one side to form a series of shoulders, ac, and to the adjacent face of .the wheel w N` is pivoted a lever, T, provided with a rollerstud, 30, `and a spring, 3l, tends to throw the lever T in the direction of the arrow, Fig. 8,

and when so thrown the stud 30 is brought `into a position to be struck by one of the shoulders ofthe wheel S. When the wheel N is in such a position that the needle K is lowered and the compressor is at rest, a pin, 32, extending from the lever T through an opening, y, in the wheel N,will strike a weightedlever, U, pivoted to the frame of the machine, which will tilt the lever T to such a position as'to carry the stud 30 away from the path` of the shoulders so that the sprocketwheel S will revolve without imparting mo- -tion to the wheel N.

To the shaft 4 is pivoted loosely a foot, V, connected by a link, 33, to the weighted lever U in such manner that the weight 34 tends to `raise the inner end of the lever and lift the .foot to theposition, shown in Figs. 2 and 3 .armwL also ,presses against the'foot V, butj To efdoes not affect the position of the latter until such an amount of grainhas accumulated between the compressor-arm and the packers as to cause a pressure upon the foot sufficient to depress the same and lift the weight 34, and by changing the position of the weight the amount of pressure which will thus become necessary to move the foot may be varied as desired. When the foot is depressed, the inner end of the lever U is carried downward and away from the pin 32 of the lever T, which is then thrown to such a position that the succeeding shoulder .r of the sprocketwheel S will strike the stud 30, and thereby carry the wheel N around with the wheel S until a revolution is completed, when the pin 32 will again strike the lever U, which has returned to its upper position in consequence of the removal of pressure upon the foot resulting from the discharge of the grain.

In order to prevent the grain from being so freely fed by the packers after the needle begins tovrise, I provide a light frame, W, Figs. 3y and 5, which is lifted as the point of the needle rises above the platform, and thereby holds the mass of grain in such a position as not to be caught by the packers. Such a frame may be differently arranged and raised and lowered in diiferent ways. As'shown in Fig.3, it consists of a narrow plate pivoted at the rear end, o2, to the platform G, and provided at the front edge with a roller, 40, and of such size as to extend over the point of the needle when the latter is down, so that when the needle rises it lifts the frame to the position shown in dotted lines, Fig. 3, thereby lifting with it the grain to such a height that the packers will take but slight hold upon the grain, thus avoiding packing' the same against the rear edge of the needle. The sprocket-chain R passes around a sprocketwheel, R', formingpart of the bevel-wheel R2, meshing with the bevel-wheel I, and the said chain also passes against the under side of the sprocket-wheel S and around a sprocket-wheel, 4l, upon the packer-operating shaft 6, and also around a sprocket-wheel, 42, upon a long shaft, 43, at the rear of and parallel to the angle-bar D, which shaft carries at the end a crank, h6, connected with the usual cutter-operating pitman, k7. The supplemental packer-shaft l2 is driven from the shaft 43 through the medium of two sprocket-wheels, 44 46, and a sprocket-chain, 45.

It is very desirable to sometimes shift the grain which falls upon the platform so as to throw its center as nearly as'may beto aposition to be encircled by the cord, and to effect this purpose I make use of a vertical endless adjusting-apron, 48, carried by two rollers, 50 5I, in a swinging frame, 49, which may be swung around a vertical shaft, 52, carrying the roller 51, by means of an adjusting-rod, 53, extending to a position adjacent IOO IIO

ISO

to the driver-s seat. The band.48 travels in Y of the band catch upon the butts of the grain and gradually shove the latter backward on the platform to the desired position. The shaft 52 is driven from the shaft l2 through the medium of gear-wheels 5l 55, as best shown in Figs. 1 and l.

The platform-frame B2 of the harvester part of the machine is connected to the frame of the binder by means of two arms, G0 61, bolted to the platform, (see Fig. 2,) and pivoted to the shaft 43, see Figs. l and 5,) and this frame B2 carries the cutter-bar 62 at the forward edge, and also carries the rollers around which travels the conveyer-belt 63, and the said frame B2 rests upon a longitudinal bar, (il, bent up at one end to form an arm, 65, and at the opposite end to form an ar1n,66, with an axle, (57, extending laterally from its end in linewith the axle B and supporting a bearing-wheel, A2, equal in diameter to the wheels A A. The longitudinal portion 6l of the rod is near the forward edge of the frame B2, so that by turning or rocking the rod in its bearings the front edge of the frame, with its cutters, may be raised or lowered to cut to any 1desired height, and it will be seen that the frame of the whole machine, including both the harvester and the binder, thus rocks upon a line, fr, Fig. 5, near the rear edge of the machine-frame, and so far from the front edge that the frame may be lifted at such front edge or depressed without imparting to it such an angle as results when the frame is supported upon bearings nearer the center. I thus secure a more extended movement without imparting to the frame so great an angle.

In order to rock the shaft 6l, I connect the arm 65 by a chain, 163, to a hand-lever, B7, in position to be readily reached by the operator.

The construction of the elevators may be best understood from Figs. 5, 6, and 7. 'lo the frame B2 are secured brackets, in which turns a shaft, 80, extending through side pieces, S1, of the elevator-frame, carrying a loose roller, 82, round which and round a roller, 83, extends the elevator-belt 84. fithin the side pieces, 81, swings the frame S5 of the upper elevator-belt, 86, which passes round rollers 87 S8, the roller S7 being earried by a shaft, S9, extending through the side pieces, Sl, and the bearings of the roller 88 turning in the frame 85, so that the upper frame can swing down against the lower belt, thereby maintaining the two belts in cont-act, even when a small portion of grain is being lifted. The movement of the upper elevator-frame, S5, is limited by a pin, q, extending through a slot, 90, in one of the side pieces,81. The side pieces, Sl, rest upon a bar, 190, at the inner edge of the platform G, and slide over the latter as the harvesterframe is lifted and depressed, so that the delivery ends of the belts are always in position to discharge the grain onto the platform. On the end of the shaft S0 turn freely two sprocket-wheels, 92 93. 0n the end of the shaft 91 of the inner roller of the conveyor-belt 63 is a sprocket-wheel, 95, and on the ends of the shafts of the upper belt-rollers are sprocketwheels 96 97. The sprocket-wheel 93 is driven by a chain, 100, from a sprocket-wheel, 98, on the end of the shaft 43, Fig. 5, and with the wheel 93 turns the wheel 92, carrying with it a sprocket-chain, 101, which passes around the wheel 92, around the wheel 97, and is held in contact with the wheel 96 by means of a guide-roller, 103. The chain 100 does not pass round the wheel 93, but is carried below the same and around the wheel 95 on the shaft 94, so that the chain 100 drives not only the belt 63, but also the elevators.

As the chain 101 drives only the upper rollers of the elevators and turns them in opposite directions, they are both efectually operated. to elevate the grain, thus avoiding the use of a duplicate set of chains heretofore generally required.

Heretofore both elevator-belts have been driven by a single crossed belt passing around pulleys on the elevator-belt shafts; 4but this is im practicable with a sprocket drive-chain,' all th'e parts of which must lie in substantially the same plane to work satisfactorily.

The knotter devices are supported at the end of the arm F, overhanging the table and having its standard nearest the rear of the machine, so that the knotter devices shall be directly in line between the drivers seat and the horses, and so that the `driver without withdrawing necessary attention from the animals is enabled to maintain aconstant watch upon the packing operations and instantly observe the breaking of the cord or any improper action of the parts.

Any suitable knot-forming devices may be used in connection with the parts already described; .but I prefer to employ those illustrated in the drawings, consisting, mainly, of a revolving knotter provided with two jaws, a cord-holding disk and plate, and a cutter.

The stationary jaw p of the knotter, Fig. 11, is secured to a shaft, 7c, turning in bearings in the head of the overhanging arm, and the movable jaw p is pivoted to the jaw p, and extends beyond the heel of the same and is provided with a friction-wheel, p2, a cam projection being so arranged upon the head as to be struck by the wheel p2 to open the jaw p at the proper time.

The shaft 7c is provided at its upper end with a pinion, 7n', adapted to engage with a reciprocating rack, k2, whereby the knotteris rotated a complete revolution first in one direction to seize and knot the cord, and then in the other to release the cord.

Heretofore the knotter, 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 IOC IIO

I avoid by transmitting-the power through part of the knotter-head.

Athe medium of the lever P,`pivoted to the side of the arm F, vibrated from below the platform. i

`The rod 21 is connected with the rack 7a2, which rack maybe a portion of a wheel, S2, as shown, the reciprocation of the rack resulting in the rotation of the pinion 7d first in one direction and then in the other.

The usual notched disk, Q', is arranged at Lthe side of the knotter in position to permit the end of the needle to pass above the same, so as to lay the cord in one of the notches,

and therevolution of the disk carries the cord into the slotq, Fig. 12, of a plate, R6, hung to a screw-pin, n', extending from the head of the arm and pressed toward thedisk Q by a flat spring, R4, bolted to the head.

`In order to insure the bending of the cord around the jaws of the knotter as it is laid thereon by the passage of the needle, I provide an auxiliary finger, 130, Figs. 10 and 10, carrying a hook, 131, at its end, adapted to take the cord stretching from the needle and press it downwardly to one side of the jaws of the knotter, and thus the catching of the cord by said jaws is insured. v This auxiliary finger is pivotally mounted at 132 to the knotterhead,and has an arm to which is connected a rod, 13 3, carried by one arm of a bellcranklever, 134, that is pivoted to the upper The other arm of this lever 1341s provided with a friction-roller extending in operative contact with a cam, 135, `formed in the front face of the reciprocating segmental wheel S2, which acts to rock said `lever at the proper times and Vthus vibrate `to the lever, so as to engage with t-he ratchet o. by the pressure of a spring, and I vibrate the lever Riso as to rotate the disk with a step-by-step motion. By applying the power to the end of the lever R5, I am enabled to apply sufficient force to turn the disk easily and prevent its movement from being arrested by the jamming of the cord in the recess of the plate R6. A rod, m2, is connected to the end of the lever R5, and connected to any moving part of the machine to reciprocate .the lever. In the construction shown the rod is connected to an arm, m3, pivoted upon a shaft, m4, Figs. 10 and 13, and secured to the bell-crank lever 134 through a connection, m5., and is thus moved in unison therewith. f

Upon a stud, 7e, projecting from the head of the overhanging arm, rocks the wheel S2, provided with radial arms, between two of which is carried the curved rack k2, and between the opposite arms extends a guard, n3, one of the arms constituting or carrying a guide plate or shield, n4, Fig. 14, and the other carrying-a knife, t, so arrangedfthat as the wheelrocks in the direction of its arrow 2 the said knife will be carried close to the inner side of the disk Q and will sever the cord between the disk and the knot.

The plate a has a curved edge which occupies-a position back of the knotter during the time the knot is being formed, and vprevents the cord from slipping off of theknotter-hook, and the jguard n3 carries a finger which is brought in contact with the knot after the latter has beenformed and while the cord is held in the jaws of the knotter, and thereby ldraws and tightens the knot upon the cord, after which a projection carried by the guard n3 passes lbeneath the lower jaw of the knotter and along a curved recess therein, and,

catching upon the loop, carries the latter off of the knotter as the cord is severed.

It will be evident that while I have shown one form of knotterand 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 knotter devices may be supported by any suitable `frame, extending over the platform of' the binder, instead of by the overhanging arm F.

IOO

In different parts of my improved machine I have used and described connections which, while effective to communicate motion between certain of such 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.
