IMPROVEMENT IN GRAIN-BINDERS.

S ecification forming part of Letters Patent No. 159,176, dated January 26, 1875; application tiled October 21, 1874.

To all whom it may concern:

Be it known that I, JosEPH MARTIN GRoov- ER, of Oxford, in the county of Oakland and State of Michigan, have invented an Improvement in Straw-Binding Attachment to Harvesters, of which the following is a specification:

The object of my invention is to provide an automatic or partially automatic attachment to a reaping-machine, by means of which a double-andtwisted straw band is made, twisted around each gavel, and the ends of the band tucked in before discharging the bundle, afresh band being made by the apparatus for the succeeding gavel while the preceding one is being banded, the operation of the apparatus being entirely under the control of the driver, who is thus enabled to govern the size of the bundles. The invention consists essentially in three mechanisms the first of which separates the proper amount of straw, and with it makes the doubled-and-twisted band; the second, which ties the band around the bundle; and the third, which tucks the ends of the bands to secure the bundle, and their combination with a harvester, one of whose pinions drives the machinery of said attachment.

Figure 1, Sheet 1, is an elevation of the rear or discharge end of the attachment, showing the band-carriers in the act of raising the band to bring it around the sides and bottom of the grain. Fig. 2 is a detail of the same, showin g the band brought around the grain ready to tie. Fig. 3, Sheet 2, is ,an inverted plan of the attachment, with the bottom board removed. Fig. 4 is a sectional side elevation of the band-former, the section being taken on the line a; a in Fig. 3. F g. 5, Sheet 3, is a side elevation of the attachment of the side next the reaper. Fig. 6 is a plan of the tucking mechanism, showing the position of the parts at the completion of the tucking process.

Fig. 7 is an elevation of the front end of the attachment, showingin detail the straw-divider. Fig. 8, Sheet 4, is an inverted plan, showing in detail, on an enlarged scale, the band-forming mechanism. Fig. 9 is a horizontal section of the same. Fig. 10 is an elevation and section of the peculiar gear which rotates the band'griper a half-revolution at each reciprocation thereof. Fig. 11 is an enlarged detail rear elevation of the band-carriers, showing the band ends raised and engaged with their holders on the ends of said carriers. Fig. 12 is an enlarged rear elevation of the mechanism which twists the ends of the encircling band together. Fig. 13 is a plan of the same. Fig. 14, Sheet 5, is a perspective view of a portion of the bottom plate and the mechanism for carrying the band back to the band-carriers. Fig. 15 is an inverted perspective view of the band-twisting mechanism.

Similar letters of reference indicate corresponding parts in all. the figures.

In the drawings, A represents the near or left-hand side sill of the attachment, and A the right-hand one, both connected by end girts, which constitute its frame, which frame is secured to the right side of the harvesterframe, so as to bring the attachment in rear of the gram-platform, from which the grain passes over an inclined apron, B, directly in rear thereof (but at the front of the attachment) onto a grain-table, 13 To the under side of the frame A A is secured a bottom board, B 0 represents a portion of the frame of the harvester proper, and to it the side of the attachment is secured. D is the drivingshaft of the attachment, and is so connected by a clutch with some part of the harvestergearing as that the driver can, with his foot, throw said shaft in or out of gear. At its inner end is a spur-gear, E, and alongside it a pulley, F, having a crank-pin, a, Fig. 3, on its inner face, to which one end of a pitman, b, is strapped, the other end of which is pivoted to the side of a cross-head, c, sliding in a slot in the side of the frame-sill A. A link, d, Fig. 3, has one end pivoted to the said cross-head, and the other to a dynamic lever, 0, whose outer end is pivoted to the frame 0 at e, and whose inner end is pivoted to a link, f, which connects it with a block, Gr, dovetailed in, and sliding in, a dovetail Way, H, Fig. 7, secured to the under side of the grain-table in the direction of its length. 9 is a shaft, transversely journaled through the block G, carrying on its inner end a spur-sector, h, keyed thereon, with a tail, h, projecting from one side, from which there is a pendent hook, W. The sector is grooved in the plane of the hook, as seen in Fig. 10. Under the forward half of the grain table the hook k and groove in the sector run on a flange or angle-iron, 2', Figs. 1, 3, and 8, while on the rear end of the travel of the block G the sector engages with a toothed rack, I, Figs. 3 and 8, which rotates the sec for h and shaft 9 a half-revolution, and on the forward stroke this motion of said shaft and sector is reversed. On the shaft g, at the other side of the block, a spur-gear, j, and bevel-gear j, cast in one piece, are sleeved thereon, with a spring spirallycoiled about said shaft in a recess in said block, to throw them outwardly against a square head, formed on the outer end of said shaft g. Through the head 9 a shaft, 7c, is longitudinally journaled, with a bevelgear, j keyed thereon, which gear meshes with, and receives motion from, the bevel-gear On the projecting end of the shaft 70 there is secured a flat rectan gular griping-plate, 70 over the top and outer part of which there is secured a spring-bail, 70 When the cross-head moves forward from the back end of its way the griping-plate is spring side up, pointing to the rear. As the cross-head moves forward the sector and its rack rotate the shaft 9 a half-revolution, brin g ing the griper to the front, when the gear j meshes with a toothed rack, I, Figs. 3, 4, and 8, which causes said gear to rotate, and with it the griping-plate, which arrives under a slot in the inclined apron B spring side up; but in the meantime the spring-bail k has been caught by a hook, 70 under the edge of the table, and lifted up, as seen in Fig. 4. Un der the apron B there is a platform, 13, Fig. 3, bar ing a V-shaped notch opposite the line of travel of the griping-plate. Just in front of the notch there is erected a horizontal rail, 1, with a parting-post, Z, in the middle, and a guard-post at each end of the said rail, on which a portion of the fresh cut grain falls as the main body moves back onto the graintable, under which there is hung a Y-shaped iron frame, m, by its longer arms, pulled back to hang pendent by a spiral spring, m, as seen in Fig. 7. There is a hook, m at the end of this frame. There is also at one side of said frame an arm, which is caught by the end of the advancing cross-head, which throws up the frame through the notch in the plate B into a horizontal position, as seen in Fig. 4, in which position it stays while the opera tive parts are out of gear.

When a bundle is to be handed the straw that has in the meantime run onto the griperplate is seized by the bail-spring as soon as the parts are set in motion, the post parting the straw drawn back by the griper into two strands, which are thrown sidewise apart by the frame m. The griper, as it moves back,

rotates on the axis of its shaft 9, twisting the ends of the strands together, while their trailing ends pass on the outside of two arms, a n, Fig. 14, now standing close together, each at the extremity of a lever, J, pivoted to the bottom board, which, by mechanism hereinafter described, sweeps outwardly, each arm a carrying its end of the straw band over a curved wire guide, 0, and laying it over one arm of a band-carrier, L, pivoted to the inner edge of a girt, L at the rear end of the frame, the griping-plate having in the meantime been re olved to the rear.

The mechanism which operates the levers J J consists of an arm, J secured to the under side of the dynamic lever 0, outside the sill A, and is bent to pass below and sweep under the bottom board, B where its extremity has pivoted to it a slotted bar, J Each lever J is connected, by a pendent stud, p, with one end of a radius-link, J both of said links having their inner ends pivoted on a stud, p, pendent from a block, J sliding in a central longitudinal slot in the bottom board, B in which a pair of segmental slots are also cut to give play to the studs 19, as seen in Fig. 14. The stud 19 also passes through the slot in the bar J which is sustained by a transverse pin and a washer, as seen in Fig. 3. Just before the arm J completes its rearward movement the stud p isstruck by the end of the slot in said bar J and thus the levers J are swept outwardly in line with the girt L When the arm moves forward again these levers J are swept around to the front and come nearly together.

One revolution of the driving-shaft D moves forward the griping-plate, takes the modicum of straw, twists the ends of the two strands together, and carries the band back ready to pass it around the gavel. The driving-shaft may now be thrown out of gear, if there be not grain enough to make a bundle lying on and projecting over the rear edge of the table.

The band thus made of two strands'is of sufficient length to reach around and tie the bundle of grain.

M M are two standard-plates erected on the sills A A, partially overlapping the rear edge of the grain-table, and are connected near their top ends by a girt, M, from the center of which is suspended a vertical shaft, N, journaled in a bearing in the said girt, below which it is provided with a bevelgear, N At its lower end there is secured a horizontal bar, N at the center, its ends being slotted to serve as jaws to receive the ends of the straw band, as seen in Fig. 13, where they are held by two hooks, g, each pivoted on a shaft, q ,whose upper end is journaled through a brace, g projecting from the shaft N, and bent outwardly, so that as they sweep around with the bar N they will, when said bar lies across the rear end of the machine, catch against the pendent studs 1, which will remove the hooks from across the mouths of the slots in the bar N to allow the bands to enter. In this position the driving-gear is idle. A spring, g*, at each edge of the bar N 3 throws the hooks across the slots, and secures the ends of the band therein. The shafts q are not equidistant from the shaft N, so that their upper ends will not both catch on the pendent studs Q3 at the first half of the revolution of the shaft N, but one will catch, and the other pass under, until the revolution is complete, when both will catch on their studs. A shaft, 0, is journaled in bearings along the top of the girt M, with a bevel-gear, N at the outer end to actuate the pinion N its inner end overhanging the inner standard, M, with a clutch-pulley, O sleeved on it, which may slide along to engage with a clutch-box, O keyed on its end. A belt or chain running on the pulley F gives motion to the clutchpulley 0 When the band has been made, as described, and its ends extended, they (the ends) lie on two jointed band carriers, L, hinged to a projection at the front of the girt L. The carriers each have a rectangular socket-head, L At the rear side of the bottom of each socket there is journaled a bell-crank, r, the upper end of which is bent over the top face of the carrier at its extremity, where it has secured to it aclamp-plate, W. A spring, r acting against one arm of the bell-crank, throws down the plate r against the carrierhead, while a lever, L has its lower end pivoted to the other end of the bell-crank. The upper half of this lever is slotted to receive and slide upon a pin projecting from the rear side of the girt M at the end thereof. The lever L has a link, L pivoted to it, which link is. pivoted to the lower end of a lever, L whose upper end is pivoted to said girt M. A link, L is pivoted to the lever L a little above its ,lower end, the other end being pivoted to a bell-crank, L", pivoted at its angle to the middle of the rear edge of the girt M, the other and like system of levers being in like manner pivoted to another arm of said bell-crank, to whose third arm or angle a bar, P, is pivoted, which extends to the left far enough to couple with a frame, P, which straddles a groove in the hub of the clutchpulley O and is finally pivoted at its front end to the edge of the grain-table. A handlever, P is connected with the frame P and serves not only to draw the clutch-pulley 0 into gear with its clutch-box to rotate the shafts O N and band-twister bar N but first draws up the band-carriersL L, with the ends of the band which have been caught under the clamp-plates r which, from the weight of thelevers L on their longer arms, have been thrown up to allow the ends of said band to pass between them and the heads of said carriers. As soon, however, as the levers have commenced to raisethe band-carriers, the clamp-plates are depressed and hold the ends of the band firmly, as seen in Fig. 11, grasping or enveloping the bundle, as seen in Fig. 2, and passing them into the slots at the ends of the bar N when the further movement of the handle 1? throws the clutch of the shaft 0 into gear, when the hooks on the bar N are thrown by their springs around the ends of the band. to hold them in the slots while said bar twists them together, thus completing another step in the process.

There now remains the process of tucking the twisted ends of the band under the band itself, to keep them from untwisting, which I accomplish in the followin g maun er A cranked shaft, Q, has one end journaled in a hanger under the sill A, and the other through a vertically -slotted hanger, s, pendent from the frame 0, with a treadle, Q, pivoted at the side thereof, to raise said shaft until a pinion, E, keyed thereon is brought into mesh with the spurgear E on the driving-shaft. The crank of the shaft Q passes through a slot in a vibrating lever, B, pivoted to a block or stud, t, on the inner side of the sill A, which lever B is connected by a link, It, with the left end of a shaft, S, on which it is sleeved. This shaft is keyed through a block, a, whose shank is journaled in a horizontal slot in a segment, T, projecting from the standard to the front, and the other end is journaled in a bearing, a, so hung to the other standard as to allow it a radial movement in the horizontal plane. The shaft S has a peculiar curved hook, S secured to its middle, directly under the bar N The outer or right-hand end of the shaft S has a spiral spring, o, attached to it and to its bearing a, in such a manner as to resist torsion of the said shaft that would roll its hook to the rear. A spring, 1;, spirally coiled around and secured to the other end of the shaft S and to the block 20, tends to rotate the latter to the left, but is kept from turning by one edge resting against the rear edge of a recess in the standard, and by the front edge bearing against a cam, 10, on the upper side of the rear part of the slot in the segment T. A stop, S secured to and resting and sliding upon the top edge of said segment, keeps the said shaft from turning, so as to throw the hook toward the front.

The band being around the bundle, and having its ends twisted together, the twisted ends are tucked under the band by depressing the treadle, which throws the pinion E into gear, and vibrating the lever It, which throws the end of the shaft S toward the front. As the block it passes under the cam 10, the shaft is compelled to make a quarter-revolution on its axis, and as the twisted ends of the band lie in the hook S, the same tucks them under-the body of the band and draws them to the front, until the block it has passed to the front of the cam, when the shaft is turned back by the spring v to its normal position, thus releasing the ends of the band from the hook, when the bundle is discharged. The driver releases the treadle Q, when a strong spiral spring, U, attached to the lower the shaft S,

end of the lever B, pulls the shaft S and attachments back to their normal positions.

While the mechanism has been in gear to tie the bundle, the band-forming devices have gone forward, taken the proper quantity of grain, made a band, and laid it on the bandcarrlers, ready to tie another bundle.
