GRAIN-BINDER.

SPECIFICATION forl'ming part of Letters Patent No. 234,806, dated November 23, 1880.

Application filed January 23, 1880.

To all lwhom tt may concern Be it known that I, HENRY E. PRIDMORE, of Springfield, in the county of Clarke and State of Ohio, have invented an Improvement in Grain-Binders, of which the following is a specification.

My invention relates to grain-binding machines, but more particularly to the mechanism by which the gavel is bound and the knot tied; and it consists in the construction, ai rangement, and operation of certain mechanism, which is fully and clearly set forth in the specification, and referred to in the appended claims.

In the drawings, Figure l is a perspective view of my improved knot-tying mechanism, looking up from beneath the machine. Fig. 2 is a plan of same, looking up from beneath. Fig. 25 is afront elevation of same. Figs. 4, 5, and l5 are detached views of the cord-holder, knife, and tyinghook. Fig. Gis aperspective View of the tying mechanism proper. Fig. 7 is a section of same. Fig. S is a plan of same. Figs. 9 to 14 are views of the cord during the progress of tying the knot.

A is a binding-frame, which rotates upon a vertical axis within the bearing A. Upon its outer end, and free to slide thereon, is an oblique sliding plate, B, which is provided with a rack, C, slot D, and a cam-projection, E.

Motion is imparted to the slide B by means of the lever F and connecting-bars F and F2, the bar F being in its turn operated by the cam-plate G, to which it is connected by the pin f. This cam-plate G is pivoted to the frame A at G. It is provided with a camslot, g, and a small pivoted cam, h2, which is pressed against a pin or projection by a spring, and which operates the knife to sever the cord.

Working in the cam-slot g is aroller or pin, h, which is attached to the end of a bar, H, guided by a link, h. This bar H operates the knife to sever the cord when it is drawn back by the roller or pin 7i striking the cam h2, as hereinafter set forth.

The cord-holder I is pivoted at I obliquely to the frame'A, and is provided with a pin or roller, z', which works in the slot D, and thereby governs the motions and time of movements is thrown up or allowed to be depressed by the cam-piece E, and insures the movement of the holder, so that it shall be thrown to or .from the tying mechanism proper at the required instant. rIhe holder, when thrown out, rests against a pin, a, onl the frame A.

The jaw J, carrying the knife, slides in a box, J', secured to the holder I, and is connected to the bar H by the pin jf. The end of the jaw is provided with two teeth, j and j', which work between two teeth, k 7a', on the holder I, as shown in Fig. 5. l/Vhen the teethj and 7c pass each other the cord is severed.

Secured to one side of the holderIis a springfinger, L, the end of which is between the teeth jf and k. The oord is held between the tooth k andlinger Ii, the springing action of the latter insuring a rm hold.

Upon the holder I is secured a tying-hook, M, which can be set forward or back with referenee to said holder by means of a screw, m, which, when tightened, presses it forward, and when loosened allows the resilience of the bent rear arm to draw it back. 4

The knot-tyer proper, N,`is secured to the frame A by the foot a, which passes through the slot I) in the sliding plate B. The casing N', open on one side, is secured to or forms part of foot n. A pinion, O, is held within said casing by a shoulder, the outer face of said pinion being formed into an incline plane, 0, and terminating in a hook, I). Within the casing N and pinion O is another piece, Q, which is secured to the easing and has an opening, q, all the way through it. At the outer end, and on one side of the opening, is a projection, S, and on the other side is piece It, attached to a spring, r, which is secured to the piece Q at the inner end, as shown in Fig. 7. The hook M, attached to and operated by the holder I, is thrust through between the projection S and piece It when the loop is being made, and when withdrawn it carries the ends of the cord with it through the loop, tightening the knot by the springing action of the spring r and piece R. The pinion O meshes with the rack G, and as said rack is reciprocated the looper composed ofthe pinion, with its inclined plane and hook, is rotated 5o of said holder. There is also a pin, i', which first in one direction and then in the other.

Secured to the casing N is a shield, n', which covers the rack and prevents the cord being caught therein.

The knetter and its appendages are set in an oblique position with reference to the grain table or platform for the purpose of properly presenting the bindingcord to said knottei, that in its revolution it shall catch and loop the cord in such a manner that the cords shall remain distinct and the loop easily operated upon.

Secured to the frame A is a curved finger, T, which partly encirclcs the looper, the end resting on the inclined plane until the hook P reaches it, when it is pressed out, thereby allowing the loop which had been previously kept between the iinger and incline plane to pass to the other side of the finger prior to the final action in tying the knot.

The hook P is so constructed that the opening forming the hook is parallel to the axis of rotation of the looper, or to the axis about which said hook rotates. Thisis clearly shown in Figs. 6, 7, and 8.

The guide U, secured to plate A, insures the proper presentation of the cord to the knot-tyer. A platform, V, is secured to the frame A and rotates with il'. Situated over the platform is the biiider-arin YV, which presents the cord to the knot-tying mechanism. It is secured to the end of arocking shaft, W', which rocks in bearings X X. The cam-plate G is oscillated by any suitable means.

The operation is as follows: The cord being placed in the holder and passed around the gavel, as shown in Fig. 1, the binder-arm W descends and presents the cord to the holder. The cord is then as shown in Fig. 9. The cani plate G is then oscillated, which action draws the teethjj in and holds the cord firmly. It also throws out the plate B and rack C, which rotates the looper, the hook P catching the cords and carrying them around to forin the loop. The roller t', following the cam-slot D, causes the holder I to be projected toward the looper, giving cord wherewith to make the knot. As soon as the looper has made one revolution the cord is in the form of a loop, as shown in Fig. 10, the hook P being at the point y. As the looper continues its revolution the loop is ready to slip from under the finger T, as shown in Fig. 11, in which yindicates the position of the hook P. As it continues to rotate the pin h passes the cam h2, pressing it up. The plate B moves the end of the cam-slot D to the roller i, projecting it and the entire holder toward the looper. At the saine time the loop is freed from the finger T as the twister rotates, and the cord assumes the position shown in Figs. 6 and 12, in which last gure y shows the position of the hook P. During the movement of the holder I toward the looper the hook M is projected to its greatest extent through the piece Q, and presents the hook to the part of the cord next to the holder, as shown in Fig. 6. The cam-plate G is then oscillated in the opposite direction. When the pin 7L strikes the cani h2 itis drawn back, which action draws the knife-tooth j farther into the holder and severs the cord. The looper is now rotating iii an opposite direction, which frees the loop from the hook P, and at the same time the holder recedes, carrying with it the hook M, which, in turn, carries the ends of the cord through the loop, as shown in Fig. 13. The cani-plate G still moving, the holder is thrown back and the jaws opened for the reception of fresh cord from around a new gavel, and at the saine time the hook M carries the ends of the cord down between the projection S and the spring-head It, which tightens the knot, as shown in 14. The bindenarin is thenraised and the bundle discharged from the platform.

Having now described my invention,what I claim, and desire to secure by Letters Patent, is-

l. A looping-head, N, in combination with a cord-holder, I, a tying-hook, M, carried by said holder, and devices by which the holder is operated in such a manner that suiiicient cord is delivered to make the knot without taking any from the bundle, substantially as and for the purpose specified.
