GRAIN-BINDER.

SPECIFICATION forming part of Letters Patent No. 280,461, dated July 3, 1883,

i Application filed August 7, 1882. (Model.)

My invention relates to improvements in.

grain-binders which are adapted for use in connection with harvesters or gleaners, and in which twine is used for the binding material 5 and my invention relates more particularly to that class of grain-binders in which the knottying mechanism is carried by the binder-arm; and the obj ects of my improvements are to simplify the construction and arrangement of the mechanism which operates the twine grasping, knotting, and cutting devices in their relation to each other, and also the movement of the binder-arm, to insure a positive action of the parts, and thus render their operation effectual and certain. I attain these objects .by the mechanism illustrated in the accompanying drawings, in whichl Figure 1 represents a perspective view of the binder-frame to be attached to the side of a vices, but with these parts removed to show the switch for operating the twine-holder. Fig. 6 shows perspective views of the upper and under side of the shield carrying the track and switch used to operate the twine-cutter. Fig. 7 is a perspective view of the upper side of the pivoted arm carrying the twine cutter and holder. Fig. 7 is a perspective view of the twine-cutter. Fig. Sis a perspective view of the under side of the same. Fig. 9 is a perspective of the twine-holder detached. Fig. 10 is a perspective view of the end of the binder-arm carrying the knot-tying mechanism. Fig. 11 is a top view of the same with the top plate removed. Fig. 12 is a view of the under side of the said top plate. Fig. 13 is a side view, on an enlarged scale, of the binder-arm with the side plate removed. Fig. 14 is a perspective view of the-hook used to retain the ends of the twine in forming the knot with its operating rod and lever. Fig. 15 is a perspective view of the swinging arm used to remove the knot from the knotter and force it close to the gavel. Fig. 15ah is a modification of the device to remove the knot from the knotter. perspective view of the pivoted nippers used to carry the twine to the knotting-head. Fig. 17 is a top view of a portion of the shaft operating the grain-feeding fingers and the retracting-spring therefor. Fig.` 18 is a transverse section of the binder-arm shaft with the eccentric and lever used to operate the grainfeeding fingers.

In the drawings, A designates the inclined frame usually found in elevated delivery-harvesters to carry the. rollers c of its elevatingaprons. To the frame are secured the lower sills, A', of the machine, and also at a suitable height the horizontal beams A2, carrying the shaft B of the binder-arm B. When the grain has reached the top of the elevating apron, it is received upon slats a, between which project the fingers a?, carried by the roller c3 to advance the grain toward the binder-arm B.

Over the feeding-roller a3 there is placed a similar roller, a, having projecting ngers also to engage the grain and force it against the two arms c c, pendent from the horizontal shaft C, these arms holding it until there is enough to make a bundle. Start the machine in operation as follows: rIo one end ofthe shaft C there is secured a crank, c, having a crank-pin, c2, that enters a slot in one end of a cOImecting-rod d. The opposite end of the rod is connected with a spring-latch pivoted to the frame at d. This latch rests upon the clutch e, and keeps its ratcheted face from contact with the ratchet-face forming a part of the pulley B2, and consequently retains the shaft B stationary until sufiicient grain has collected against the pendent arms c c and elevated them, so that the crank-pin c2 will bear against the outer end ofthe-slot, and pulling the connecting-rod d lifts the latch D off the seat and permits the clutch e, under the Fig-.161s a' IOO impulse of the spring c upon the shaft B, to come into mesh with the ratchet upon the pulley B, and thus give motion to the shaft B, the clutch being connected to the shaft by means of a feather and groove, as is common. When the bundle is complete and removed, the shaft B comes again to a stop by reason of the bev` eled side of the latch D bearing against the projection e2 upon one side of the clutch and forcing it away from the pulley. This pulley B2 receives a constant rotary motion from the chain b2, leading from the pulley a upon the end of the shaft of the roller a of the elevating-apron of the harvester. This chain gives at the same time a constant rotating motion to the grain-feeding roller a c4 by passing over the pulleys a upon their shaft. As the chain bt does not encircle the pulleys c5 and c, it is retained in close contact therewith by means of tension rollers or pulleys al, mounted upon an arm, A, pivoted at c to one end of the beam A2 of the frame. The free end of this arm A3 is kept down by means of a latch, A, bearing upon it, and this latch is pivoted to the frame A at c, so that by partially turning it the arm carrying the tension-pulleys can be rocked and the chain can be loosened and mili nked. Just before the end of the binder-arm is ready to descend and enter the grain received from the feed-roller a3, said grain is separated from the grain just elevated and rapidly advanced and compressed against the binding-twine and against the pendent curved arms E by the jointed arms F. These arms F, as well as the arms E, are pivoted atf to light overhanging beams A5, secured centrally to and over the frame. While the grain is accumulating upon and in front of the slats a, the jointed arms F occupy the position shown in Fig. 2, being held so by a spring, j", upon the shaft F, (see Fig. 19,) that transmits motion to said arms F, but when, as aforesaid, the end of the binderarm B is ready to descend, the cam B"s upon its shafts (see Figs. l and 18) bears upon the free end of the bell-crank lever F2, that is pivoted to the frame AL at f2. The opposite end of this bell-crank lever being connected by means of the rod f with the crank F upon one end of the shaft F, this shaft is rocked by the action of the cam B striking the bell-crank F2, and thus pulling upon its crank F3.

To the shaft F are secured the arms F, and the latter have links F5, pivoted at f5 to the ends ofthe arms F, opposite the ends that carry the pivoted spring-fin gers FG. The joint uniting the fingers FG to the arms F is the equivalent of a butthinge--that is, the fingers and arms will remain extended while advancing the grain, but will be folded back while being retracted to the position shown in Fig. 2.`

When the finger ends of the arms F are projected outwardly by the cam B3, they do not reach quite so far as shown in Fig. l, they being shown in that figure in an extreme position, to clearly show the parts underneath; but they swing far enough to compress the grain against the bimling-twine, the pendent arms E being locked, while the grain is accumulating against them, by the pins f, projecting from the side of the levers F, these pins becoming engaged under the shoulder E at the inner end of the arm E.

The frame of the binding portion of themachine has an inclined platform, A, to support the gavel, and through the middle ofthe platform is cut a passage-way for the point ofthe binder-arm B. The sides of this passage-way are formed ofnietal plates A7 and A8, carrying projections to operate as guides for or to actuate the ends of arms projecting from the shell or casing inelosing the knot-tying mechanism at the extremity of the binder-arm B', as will be described hereinafter.

Upon an inclined platform, A, set at some distance under the platform A, is mounted the combined twine holding and cutting device G. (Shown in Figs. 3, 4, 7, 7, 8, 'and 9.) It is pivoted to the platform AJ at g, and its free end projects in the passage-way for the binderarm, as shown in Fig. 3. lt is kept at the upper end of said passage-way by a coiled spring, y, fastened thereto at one end, and having its upper end secured to the frame above at g2. This arm G carries a straight blade, l1., having its extremity beveled to produce a knife-edge, and inclined to form a draw cut. This blade is slid endwise between guides forming a part ofthe arm G by a coiled spring, h', having one end secured to a pin, if, projecting laterally from the inner end of the .blade h, the other end being attached to a hook, gl, projecting from th e arm G. The blade h is retracted within the arm by a pin, h3, projecting from its surface, sliding against the outer side of a spring-switch, t', pivoted to and located under the cap-plate l. This cap-plate is secured to the platform A9 IOO over the arm G, andearries a curved track, i,

upon the concave surface of which the pin h of the blade h travels, and advances beyond the point of the switch i when the free end of the arm G is retracted to the top of the passage-way by the large coiled spring g. The free end of the arm G is depressed bythe side B of the shell, at the end of the binding-arm B', coming in contact therewith, the' portion b" of the shell being suitably cut away and bent for that purpose. During the first half of the downward course of the arm G the bladcs pin h3 rides against the outside of the switch t', and is thereby retracted until it reaches the pivot i of the switch. It then drops against the track 2, causing the knife to cut the binding-twine that is held in its path bythe holder k. This holder 7c is a small rectangular bar, having a notch upon one side to form a hook, k, adapted to retain the binding-twine. 'It is held within the arm G, parallel with the cutter h, with a very thin plate, g", between them.

` This holder k is kept retracted within the arm IIO permanently within this arm by a small plate, g, and is forced outward by a pin, k, passing through a slot in said plate g. The holder 7c is made to project endwise out of the arm G by having its pin 7c3 ride over the outer side of a spring-switch, Z, Figs. 4 and 5, secured to the side of the passage-way cut in the frame supporting the inclined platform A. The edge of said platform is `cut away at Z to permit the pin 7c" to be retracted by the spring k2 behind the switch Z, andI thus grab and hold the binding-twine between the hook 7c and the notch gl inthe end of the arm G before the pin h2 of the cutter has left the face of the switch t', and consequently before said cutter has been projected against the twine by its spring h.

The blade h may have both of its sides smooth', and operate successfully in connection with the holder, but I prefer to construct it with'a notch forming a hook, h, in the side thereof, so that when the cutter-blade is projected tocut the cord it shall receive in the notch the portion of cord held by the cordholder, and this holder being forced out to receive a new end beforethe cutter-blade' is projected to cut the same. This notch in the cutter-blade, by holding onto the end first caught by the holder, will cause it to be surely dropped from the holder notch or hook when it is -forced out to catch a new end. To give a side support for the cord while the blade is projected to cut it, the cap-plate g8 of the arm G is provided with a hook, g", extending beyond the end of said cap-plate to receive and hold the cord in front of the cutting-edge of the blade.

llhe binding-twine coming from the spool and tension device (not shown in the drawings) passes over or around the guide-pulley a, pivoted to the frame on top of the machine,thence to theholder 7c, and being clamped thereby, the machine is in proper condition to operate. rIhe grain fed along by the fingers of the rollers a and c* is pushed against the binding-twine and crowds it forward, so thatv when the end of the binder-arm comes down the twine extending from the pulley c to the holder enters the slot m in the top plate, M, of the casing in the end of the binding-arm, and carries itdown around the gavel to the arm G, containing the holder and cutting-blade, where it is iirst grasped and then cut, the roller n on the needle pushingA the cord behind the hook l 7c of the holder; but before the cord is cut its two ends have been seized by the spring-nip- I pers N, carried by the binder-arm, as will be hereinafter described, the cord being guided between the j aws of the nippers by the beveled or inclined plate O on the side of the needleframe. These nippers have a rigid jaw, N', pivoted to the needle @at la', and a jaw, N2, pivoted to the jaw N at n2, the two jaws being kept closed by a spring, n, secured to the jaw N', bearing against the inner side of the rear end or arm n4. The rear extremity of the arm n* projects through a segmental opening, b5, in

tion p, vsecured to the plate A7 on the side piece of the passage for the needle, and thus the portion of the cord after it enters the casing is received by the nippers. The binderarm continuing in its course, the portion of the cord adjoining the holder 7c enters also the slot m in the top plate, M, of the casing, and is also received by the nippers, the latter thus seizingthe cord at two points with the gavel between them. The binder-arm still advancing, the upper portion of the corde comes in contact with the holder lc, which, as the arm G is depressed,vfirst seizes it, and then the blade 7L cuts it at a point between the holder andy nippers in the head of the binder-arm, leaving the other part fast in the holder. The grasping end of the nippers holding` the cord Aare then carried up near to the head of therevolving hook q of the knot-tyer Q by the arm N3, attached to the outer end of the pivot n of said nippers, its roller a5 passing in the rear of the projecting track a, secured to the side plate A8 of the passage-way, andafter passing this track the nippers are restored to the position shown in Fig. 13, by the spring no (shown in Fig. l0) pressing under the arm N 3.

To bring the band between the knottinghook q and the conical end of its tube, guides and latches are secured to the plate M of the knotter-casing and to the sides of its passageway, as follows: To the under side of this plate M (shown in Fig. 12) is pivoted the latch m upon one side of the slot m, to close the inner end of the latter after the ends of the cord have entered the opening M/ in said plate, the spring m2 pressing against the side of said latch, and the cord is prevented from going too far in the opening M by an arm, m3, pivoted to the top of the plate M at m4. A spring, m5, pressing against its end m, adjoining its pivot fm, causes its end m7 to press against and be locked by the spring-latch m8, pivoted at lm, said latch being so locked by having its end m come in contact with the projection m13 on the end of side plate AT. The latch m8 releases it at the time the knot is nearly completed by having its end m10, that projects over the edge 'of the plate M, coming in contact with the pin m12 on the `side A8 of the binder-arm passageway. The arm m3, its spring m5,'and the latch m8, with its spring, would in practice be placed under the top plate, M, to protect them from contact with the straw. rlhe ends of the cord are also forced sidewise againstA and within the hook g of the knot-tyer by the arm R, pivoted to the frame at r and lying across the passage-way of the binder-arm, with its guiding-notch r2 in or near the middle thereof.

IOO

The arm is brought to a horizontal position across said passage-way by the spring r pressing` upon its inner end. lts other end is kept locked, except at the time the binder-arm B passes it, by means of a spring-latch, R2, pivoted tothe frame at o, and this latch is retracted by the side of the plate M coming in contact with its side arm, o".

The cord surrounding the gavel has its two ends retained by the nippers N after passing through the opening between the end of the latch m and the arm on in a position close to the knot-tyer Q, so that when hook q, occupying the position shown in Fig. 1l, revolves, it carries with it the two strands of the band once around the knot-tying head, and then the hook q closes upon the strands at the point nearest to the nippers and pulls them through the loop lying around the head in the ordinary manner of this class of knot-tying devices, the nippers releasing` the ends of the cord by having their arm a" coming in contact with the projection of on the side plate AT of the passage-way. To revolve the knetter Q, there is mounted thereon a pinion, Q. adapted to mesh with a rack, QF, secured to the side plate AS of the passage-way; and to stop the momentum of the pinion as soon as it has made a revolution, there is a spring-pawl, s, made to engage with the teeth ofthe pinion. This pawl is pivoted to the frame B of the knotter frame or easing at s, its spring s2 keeping it in engagement with the pinion except when the outwardly-projecting end s" of the pawl bears against the projecting track Q located under and following the rack Q2.

The knetter-hook q has its inner end pivoted to the rod q2, having one end formed with a head, q, that is received between the prongs of its operating-lever q". This lever is pivoted at q", about the middle of its length, to the fra-ine B6 of the binder-arm. Its other end is forced outward by a spring, q, and it carries a roller, ql, adapted to travel upon the raised track r 1`-, secured to the frame in the lower portion of the passage-way to pull the rod q2 and complete the knot.

To remove the knot from the knotter-head and tighten it as close tothe bundle as possible, there is within the casing an arm, T, pivoted to the frame Bn at t, so that its extremity T can be elevated. For this purpose, its pivot or axle t is provided with an arm, T2, carrying at its end a roller, t2, that is depressed by coming in contact with the projection t upon the plate AS of the passage-way at the moment the knot is removed from the knotter, otherwise the arm T2 is kept elevated by the spring t pressing under it. The end T of the arm T in Fig. 15 is concave to embrace one side of the knetter-shank, and it carries a horizontally-swinging arm, T, having a perforation, It, which encircles the shank of the knotter-llead. This arm T is pivoted to the arm T at i, and is made to bear sidewise against the knotter-head, and tightens the knot by a spring, t7, the length of oscillation of said arm T being limited by the pin t, projecting from the arm T. This knot-removing device is practically effective; but the action of the spring t7 being somewhat sudden, I prefer the construction shown in Fig. 15, in which there are standing up from the top of the frame B" two guide-rods, u and u, having their upper ends bent in opposite directions, and between these rods are placed upon the arm T two plates, T and T, retained connected to the arm T by pins 1f', passing loosely through slots in the plates T and T". The plate T has its end concave to bear against one side of the knotter-shank, and the plate T3 has an opening, t, the interior surface of which bears against the opposite side of the knetter-shank. These plates have grooves u in the sides to receive the guides a and a; and it is evident that when the free end ofthe arm T is elevated and brings the grooves a3 against the curved faces oi' the guide-rods u a, the plates T and T" will be moved in opposite directions. The grooves u2 are shown as cut from the sides ol' the plates T and Tl; but they may be eut from the center ofthe plates by having the curved guide-rods a u secured to the frame B in a position corresponding therewith.

Upon one side of the knetter-inelosing easing or frame there is a friction-roller, l", to

guide the binder-arm against the side plate A of the passage-way. \Vhile the machine thus binds the gavel, the latter is supported bythe spring-arms V on each side of the path ol' the binder-arm. They are pivoted to the frame at c, and to their heels is attached the coilspring t, having its lower extremity secured to the cross-beam of the frame. After the gavel is bound it is ejected or delivered from the binder-arm either by its own momentum and weight or by an arm upon a rock-shaft, or by other suitable means.

The same binding-arin, with its cord holding and tying mechanism,may be made to operate with a gleaner and revolve in the opposite direction from the one above described by inverting and changing from one side to the other the side plates, A7 A, ofthe passage-way as well as the cord-holder and cutting-blade.
