HARVEY R. INGLEDUE, OF GRAY, IOVWA.

GRAIN-BINDER.

SPECIFICATION forming part of Letters Patent No. 311,4-92, dated February 3, 1885.

(Model) T0 at whom, it nuty concern:

Be it known that I, HARVEY R. INGLEDUE, a citizen of the United States, residing at Gray, in the county of Audubon and State of Iowa, have invented certain new and useful Improvements in Grain-Binders; and I do hereby deelarethe following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

My invention relates to improvements in that class of grain-binders in which cord is used as a binder and a square or reef knot is formed, and has for its principal object the arrangementand construction of mechanism whereby the sheaf is bound as tight-1y as it is compressed, and whereby a great saving of cord is also obtained. My further object is to produce simple and efficient means for tying a knot of the form mentioned.

My improvements are illustrated in the accompanying drawings, in which Figure 1 is a perspective view of the mechanism; Fig. 2, a plan view; Fig. 3, a front elevation showing the position of the cord in the first and second steps of the operation in forming the knot; Fig. 4,21 detail view showing the position of the cord and tying mechanism just after the loop has been formed by the looper; Fig. 5, a similar view showing the next step in the operation; Fig. 6, a front elevation ofthe machine, showing the situation of the parts and the position of the cord as the knot is being completed and the slack of the cord taken up on the center pin; Fig. 7, a view showing the position of the cord and knot-tying mechanism at the last stage of the operation, and just before the knot is completed and the cord severed; Figs. 8 to 14, inclusive, are detail views of different parts.

Like letters and figures represent like parts throughout the several figures.

A represents the frame of the machine, which is properly constructed to be attached to the ordinary forms of harvesters now in use.

B is an incline which receives the grain from the apron of the harvester.

O is the cord-carrying or needle arm, of the usualform, having an eye and a grooved back. It is provided with aspring tension device, a, for controlling the tension of the cord as it comes from the cord-reel a The needle-arm is attached to a shaft. D, supported in bearings in the brackets d d, wh ch shaft is operated by means of the slotted connecting-rod E and the cam mechanism on the main shaft F. This cam mechanism consists of the wheel G, provided on its inner face with a'camgroove, c, which forms a track for the friction-roller g on the connecting-rod E. The

slotted end of the rod E incloses the main shaft F. The main shaft is rotated by the band-wheel H, to which motion is communicated by a band from the harvester. The needle-arm is thus given its alternate forward and backward movement. In the present form of machine I use a spiral spring, h, to form a springconnection between the shaft of the needle and its actuating mechanism, to allow said needle to yield to avoid breakage.

In order that the movements of the needle arm may be exactly understood, I have shown in Fig. let a detail view of the face of its actuating cam-wheel. The camgroove e is composed of four different sections or ares, e, e", e*, and The arcs c and c are both concentric with the main shaft F, the radius of the are 0 being greater than that of the are c". The are c, which connects the arcs c and cf 011 one side, is a re-entering are, and the are e is a rising incline connecting the arcs e and c on the other side. As the cam-wheel rotates in the direction of the arrows in Figs. 1

and 14:, thepath of the roller 9 on the connecting-rod E in the can't-groove 0 will be n the opposite direction. The resulting movements given to the needlearm bygthis cam-wheel are as follows: The are 6 being farthest from the center of the shaft F, when the roller 9 is in this portion of the cam-groove the needle-arm will occupy'its most rearward position, the position being that indicated in Fig. 7. As the cam-wheel rotates the roller 9 first enters the re-entering are c, and thus throws the needle-arm forward, the needle'arm reaching its most forward position (that shown in full lines in Fig. 3) when the roller reaches the deepest part of the are e at 6 After passing this point the roller commences immediately to rise, at the same time carrying the needlearm back until it enters upon the are c. The are 6 having a shorter radius than the are c, the needle-arm does not occupy during the continuance of the roller in the are 6' its extreme rearward position, but an intermediate position, its position during this interval being indicated by dotted lines in Fig. 3. When the roller enters upon the rising are 6 it carries the needle-arm back until it completes its path by entering into the are e, the needle-arm being thus returned to its original rearward position.

I is a gripping and cutting device consisting of the two armsjj. Theinner end of the lower arm, 7', is pivoted to the top of a standard, Z, on the frame A. The outer end of arm j is curved, and is provided with a projecting lip, Z The upperarm, j, is pivoted to the lower armatm and is rovided withas rin m and a cutting-blade, m, which extends along the side of the projecting lip 2*. The spring at serves to keep the jaw of the upper arm normally closed on the lip Z of the lower arm, in order to hold the end of the cord between them at the beginning and at the end of the operation, and also, as hereinafter described, to furnish sufficient force to the cutting-blade to sever the cord after the sheaf is bound. The jaws of these two arms are separated to release the cord at the proper time by the operation of the arm K, pivoted to a standard, a. One end of this arm is slotted to receive the inner end of the upper arm, j, and to permit the latter to move laterally, and the opposite end of arm K is provided with a wheel, a, which rides on the periphery of the cam n on the shaft F, as shown in Fig. 12. The gripping device is given an intermittent reciprocating movement by means of the connecting-rod L, which is attached at one end to the lower arm, j, and at its opposite slotted end to the main shaft F, and is provided with a friction-roller, Z, working in the groove m of the cam-wheel M. The object in giving the gripping device this intermittent reciprocating movement is, first, to carry the free end of the cord forward to a certain point toward the device for forming the loop, so that the loop can be properly formed; and, second, to carry the same end of the cord farther forward beyond the looping device, so that it may be returned through the loop thus formed, all as hereinafter described.

0 is the looper and pincher for forming the loop and seizing the end of the cord after it is carried through the loop by the gripper, and for retaining that end of the cord until the knot is tied. It is composed of two parts an upper part consisting of a horizontal shaft, 12, secured in bearings on the frame and terminating in a curved head, 19, forming a jaw the inner face of which is corrugated, and a lower part, 19 pivoted to the upper part at r and terminating in a rounded upturned jaw, 10 to correspond in form with the jaw on the upper part of the looper. The part 19 is provided with a projectinginclined piece, 8, around which the cord is wound in forming the loop, and at its back it is provided with a spring, 2?,

the end of which bears on the back of the upper arm,p, and which serves to hold the jaws of the looper together when the cord is held between them. The piece 8 may be made'sim'ply as a solid projection of the lowerjaw. To form a loop in the cord this looping device isgiven one entire revolution, first turning upward and inward in the direction indicated by the arrow in Fig. 2. It is rotated at proper intervals by means of the bevel-pinion V, secured on the shaft 1), and engaged by a segment-gean. W, on the face of the wheel P, which wheel is mounted on the main shaft F. After the loop is formed by this revolution of the looping device its jaws are opened to permit the free end of the cord held by the gripping de vice to be carried back through them. This motion of the looper-jaws is accomplished by the action of the bell-crank lever B, pivoted to the standard 2. The arm 1" of this lever extends forward and terminates in a rounded head, 8, which works on the beveled end of the lower part, f, of the looper, and the arm 1 extends from the fulcrum on the standard 2, at right angles with the arm a, and is provided at its end with a friction-roller, 1". This roller 1" is met at proper intervals by the rounded lug r on the face of the canrwheel S, mounted on the main shaft F. WVhen this lug engages the roller 1", the head 8 of the arm 1* is pressed against the beveled end of the part 12 of the looper, thus forcing the jaw of that part open,and holdi ng it open long enough for the gripping device to pass between the jaws of the looper. These jaws are then immediately closed upon the cord by the action of the spring t. The head of the looper, immediately after the operation last mentioned, is dropped to a position shown in Fig. 6, in

order that the loop formed thereon may be readily drawn off onto the center pin, T. This downward motion is accomplished by the contact of the lug t on the face of the wheel P wit-h the lug t on the horizontal shaft 19. After the loop is formed and drawn onto the center pin, as more fully hereinafter described, the head of the looper, still retaining the end of the cord between its pinching-jaws, is thrown upward to its original position by the contact of the tooth VV on wheel P with the beveled pinion V on the horizontal shaft 1). The lower jaw of the looper is finally opened to permit the free end of the cord to escape when the knot has been tied, by contact of the lug .90 on the can1-wheel with the head 1* of the lever B. A collar, P, on the shaft p'is provided with a flat surface, as shown in Fig. 10, with which surface the projecting ridges s s on the face of the wheel P engage, thus preventing the shaft 19 from turning at those times when the looper is required to be stationary, and when itsjaws are open.

T is a reciprocating swinging conical center pin, supported by and sliding in the arms 3 and 4 of a hanging bracket, W attached to the under side of the lower arm, 9', of the gripper 1. It is swung forward and backward with the gripping device, and by the same mechanism. It is also given a longitudinal reciprocating motion in a direction toward andfrom the looper by the action of'the forked lever Y,pivoted to the standard lon theframe A, the forked ends of said lever embracing the pin and resting between the flanges of a collar, Z attached to the center pin between the arms 3 4 of the bracket W' Said leverY has a short arm, 5, extending beyond its fulcrum in the standard 4, and provided at its end with a friction-roller, 6, which works in the cam-groove 7 of the cantrwhecl S. By the action of the cam-groove on the arm 5 the le ver Y is thrown from side to side, and its forked end moves nearly from one side of the bracket XV to the other within the arms 3 4, and this is consequently the distance through which the center pin, T, is made to slide forward and back. This pin is called the center pin because it is located between the gripping device and the looper. \Vhen the knot is being completed,it forms a bearing on which the folds of the loop are gradually tightened until all slack in the cord is taken up by the receding movements of the needle-arm and the looper. As. an aid to this operation, and to prevent the cord from being drawn too tight upon the center pin while the slack is being taken up and the knot is being completed, the pin is provided with a guard, U, which also has its bearings in the arms 3 4 of the hanging bracket NV", and is attached to the center pin by means of the collar Z and has the same sliding motion. The construction of the guard U and its arrangement on the center pin are shown clearly in Fig. 13. It will be seen that the guard is not as long as the center pin, and it stands out from the latter at a distance back of its point, and approaches closely the surface of the center pin near the point where the latter begins to taper, thus forming a spring which yields to the pressure of the cord drawn around it, for the purpose already mentioned. As the knot appreaches completion it reaches the tapered end of the center pin, and as it slides off the pin it is tied tightly against the sheaf.

The operation of the machine when attached to an ordinary form of harvester is as follows: The free end of the cord is taken from the reel, passed through the hole at the heel of the needle-arm, laid in the groove on the back of the arm, passed through the eye in its point, and is then secured between the jaws of the grasper. The grain passes up the apron and falls upon the incline and against the cord, which it carries back. The needle-arm rises through a slot in the incline, carrying the reel end of the cord around the opposite side of the bundle, down by the outer side of the looper and across the end of the cord held by the graspers, as shown in Fig. 3. Tie center pin is then advanced above both cords, which are crossed, as shown in Fig. 3.

same.

The needle then recedes, carrying the cord over and back of the jaws of the,looper, as shown in dotted lines in Fig. 3. The center pin, as the needle-arm recedes, tends to prevent the cord from slipping over the head of the looper. The looper then rotates, turning toward the back of the machine, and, making one revolution, forms aloop, as shown in Fig. 4. The projecting head or jaws of the looper during the last part of their revolution pass under the cord where it is crossed, and between it and the sheaf. During the formation of the loop, and before the looper has completed its revolution, the center pin and gripping device are moved farther back laterally. so that the looper completes its rotation with its jaws on the opposite side of the center pin. The head of the looper,after thus passing under the cord and lifting it up, resumes its original position. Its jaws are then opened to permit the gripping device carrying the end of the cord to ,move back between the The moment this end of the cord is carried through the jaws of the looper they close upon it. At the same time the gripping device opens, releasing the said end of the cord. The position of the parts at this step, and just before the gripper releases its hold of the cord, is shown in Fig. 5, and their operation thus far has resulted in forming the loop and the outline of theknot. The cord is now in position to be drawn together to form the solid square knot. cedes. The head of the looper falls and the knot is drawn off onto the center pin, as shown in Fig. 6, thejaws of the looper still holding the end of the cord tight. As the needle-arm continues to rccede the head of the looper rises, still holding the end of the cord. As the looper reaches its original position, as shown in Fig. 7, the knot is carried off the center pin, and the reel end of the cord is carried back over the projecting lip of the grasper by the needle-arm. At this moment the upper spring-arm of the grasper descends upon the reel end of the cord, its knife severs its outer end,while the inner end is retained, and simultaneously thelooper-jaws open, thesheaf, tightly bound, falls to the ground, and the machine is in position for another operation.
