KNOTTER FOR GRAI'N-BINDERS.

SPECIFICATION forming part of Letters Patent No. 525,672, dated September 4, 1894.

Application filed November 1, 1886. Serial No. 217,679. (No model.)

To all whom it may concern.-

Be it known that we, WILLIAM N. WHITE- LEY and WILLIAM BAYLEY, citizens of the United States, residing at Springfield, in the county of Clark and State of Ohio, have in-' vented certain new and useful Improvements 1n Knotting Mechanism for Grain-Binders; and we hereby declare the following to be such a full, clear, and exact description of the invention as will enable any. person skilled in the art to which it pertains to construct and use the same, reference being had to the accompanying drawings, forming'a part of this specification.

Our invention relates to that class of automatic grain binding harvesters wherein the cut grain is delivered upon an inclined binding deck, where it is formed into a gavel and encircled by the binding cord by proper devices, after which the binding cord is auto matically tied and that surrounding the bundle severed from the remaining cord, and the bundle discharged.

Our invention consists in certain devices and combinations whereby the knot is formed, the cord severed and the knot stripped from the tying device; and is in the nature of an improvement upon the knotting mechanism described in Letters Patent No. 212,420, granted to F. Appleby February 18, 1879, with the varlous modifications thereof in general use.

The new features of our invention are hereinafter fully described and particularly pointed out by the claims. These several novel features are illustrated in the'drawings hereto attached, in which-- Figure 1, is a side elevation showing the knotter-hook, tyer-wheel, (to. Fig. 2, is an elevation of the opposite side, showing the cord-holder, tucker-finger, their operating cam, &c. Fig. 3, is a plan of the complete knotter. Fig. 4., is a plan of the breast-plate, tucker-finger, &c. Fig. 5, is a side elevation illustrating the swinging arrangement of the knotter-hook, &c. Fig. 6, is a vertical section through the knotter-hook, looking from the rear. Fig. 7, is a similar section looking from the side. Fig. 8, is a side elevation of a portion of the frame, showing in vertical section, the arrangement of the tucker-finger shaft, 850. Fig. 9, is a front elevation of the cord-holding and cord-severing device. Fig. lO, is a side elevation of the toothed segment 'for operating the tucker-finger and cordholder disk. Fig. 11, is a plan of the toothed segment and tucker-finger gear.

15 to 19 are detail views illustrating the various relative positions of the tyer wheel and pinion. i

Similar letters refer to likeparts in the several views. I

In the drawings A, is a casting constituting the breast-plate and knotter frame formed in one piece, having the usual projection A for fixing it to the binder girt X. Formed in the frame A, is the needle-arm case a, within which the needle-arm passes as it encircles the sheaf with the binding cord and lays the latter in place across the knotter-hook. The binder shaft 12, passes througha proper perforation at the top of the frame in the usual manner and has the tyer-wheel B, fixed to it at one side of the frame A, and an additional cam-wheel C, at the other. Each of these cam-wheels has an ejector arm Z, formed upon it.

The knotter-hook D, is journaled in the.

swinging carrier E, which is pivoted to the frame A, at e, and has an arm for-med upon it carrying the friction roller e which engages a. cam-track formed in the tyer-wheel B, for the purpose of swinging the knotter-hook toward the cord-holder as the former rotates in order to furnish slack cord for forming the knot and backward to assist in stripping the knot from the knotter-hook. This device is shown in detail in Fig. 5.

The pivoted jaw d of the knotter hook is opened and closed by a plunger d working vertically through the knotter-hook stem and connected to the pivoted jaw 01 by a link (1 as shown in Figs. 6 and 7. Pivoted in the top of the plunger 01 is a friction roller d, which engages the cam 11 formed on the hub of the tyer-wheel, and the knotter-hook tongue is opened thereby and closed by the spiral spring d surrounding the plunger (1 and within the knotter-hook stem in the usual manner.

The cord-holder F, and cord-holder disk G, are pivoted to the frame and the-cord-holder provided with the spring f, in the usual manner. Upon the same stud on which the cordholder disk G, turns is also pivoted the lever H, upon one end of which is formed, or fixed the cord-severing knife it, while upon the opposite end is pivoted the pawl g, which rotates the cord-holder disk G. The'lever H, is operated by the toothed segment J, to which it is connected by the rod j, which is made in two parts, one screwing into the other as shown in Figs. 1, and 2, for the purpose of rendering it adjustable as to its length. The cord-holding and severing device is shown in detail in Fig. 9.

The tucker-finger K, is formed as shown in Figs. 2, 4, and 8, and pivoted upon the pivotbolt is, which is threaded where it passes through the lower portion of the frame A, and its upper end reaching the depth of the hole in the upper part of the frame A, as shown in Fig. 8, This mode of construction is adopted for the purpose of spreading the two bearings of the pivot bolt is, so that the tubular part of the tucker finger shall not bind and become immovable by any strain which tends to force these two bearings together. WVhen properly adjusted the pivot-bolt k, is secured by the pin 70 The tucker-finger is operated by the toothed segment J, having teeth 3' formed thereon, which engage the teeth k formed on the upper end of the tubular bearing of the tuckerfinger K, as shown in Figs. 10, and 11. Upon the back of the toothed segment J, is also formed a cam-track or delay rim j which engages the projection M, and holds the tuckerfinger K, in position after it has tucked the cord under the knotter-hook as hereinaf ter described. The toothed segment J, has formed upon it a projection j, which carries the friction-roller 7' which engages the camtrack of the cam-wheel O, by which it is actuated.

The cam-wheel 0, shown in detail in Figs. 12, and 13,'is so arranged that the throw of the cam is adjustable, a portion 0 of the cam-track being made in a separate piece and held in place by the adjusting bolt 0. Formed upon each of the parts are V-shaped teeth 0 fitting each other, which assist the adjustingbolt 0, in holding the parts in place. By this means the part 0 of the cam-track may be adjusted so as to throw the tucker-finger K, forward sooner or later in relation to the movements of the needle-arm and knotter-hook in order to properly place the cord on the latter for tying the knot.

The sheaf-guiding board L, has fixed to it the plate Z, by which it is pivoted to the projections m, n, of the frame, by the bolt 0. By this arrangement, in the operation of the harvester or in driving past obstructions, should the sheaf -board L, he accidentallystruck, it will simply turn out of placenta shown by dotted lines in Fig. 3, and will be thrown back to its proper position by the ejector on the tyer-wheel B, at its next revolution. 1

The operation of our invention is as follows, viz:The parts of the knotter being in the positions shown in Figs. 1, 2, 3, &c., the needle-arm lVL-advances, carrying the binding=cord across the knotter-hook and over the cord-holder disk as shown in Fig. 5. The tyer-wheel rotates, in direction of the arrow, carrying with it the cam-wheel O, which not uating the toothed segment J, throws the tucker-finger K, around under the knotterhook, and forcing the binding cord into the position shown. Thus far the toothedsegment J, has not moved far enough for the rod 3', to cause any movement of the lever H, but continuing its rotation in direction of the arrow, the delay-rim j engages the projection 10 on the tucker-finger and holds it in the position shown in Fig. 5, while the segment J, is carried around far enough to cause the rod j, to lift the outer end of the lever B, by which the pawl g, rotates the cord-holder disk G, the parts taking the positions shown in dotted lines in Fig. 9, and the cord being properly grasped and held as usual. The rotation of the tyer-wheel continuing, in direction of the arrow, the teeth S, thereon engage the teeth of the knotter-hook pinion t, and rotate it in direction of the arrowin Fig. 4. At the same time the incline p, of the tyer-wheel cam-track acts upon the friction roller e, and the knotter-hook carrier E, swings back to the position shown by dotted lines in Fig. 5, by which operation suflicient length of binding-cord is supplied to form the knot. During the rotation of the knotter-hook the cam b, has depressed the plunger (Z and opened the knob ter-hook to grasp the second folds of the cord, and the knot is formed. In the meantime the cam-track on the cam-wheel 0, acts upon the friction roller of the segment J, bringing it back to the position shown in Fig. 10, thus returning the tucker-finger to its original position and at the same time forcing the knife h, up against the binding-cord and severing it, these parts then taking the position shown in Fig. 9. The usual delay-rim formed upon the tyer-wheel to prevent the rotation of the knotter-hook in either direction, except when acted upon by the teeth provided for that purpose, is cut away at b (Fig. 15) the point upon the tyer-wheel which is now opposite the knotter-hook, by which the latter is al- I lowed to turn slightly backward as shown at r, Fig. 4, and at D, Fig. 14, the successive positions of the knotter pinion being shown in Figs. 17, 18, 19 and 15 immediately after which ejectors Z, Z, come'in contact with the bundle and force it outward, tending to strip the knot from the knotter-hook, which is still further facilitated and completed by the knotter-hook swinging away from the bundle as it is ejectedthat is, the knotter-hook swings in an opposite direction from the motion of the bundle. This is illustrated in Fig. 14:, in which the bundle is shown in dotted lines, the knotter, with the knot formed on the knotter-hook D. After the knot is stripped from the knotter-hook by the bundle and knotterhook moving in opposite directions, the latter taking the position shown by dotted lines and the cord shown by full lines.

Having thus described the construction, arrangement and, operation of our invention and pointed out wherein it differs from the usual devices employed for similar purposes, and without wishing to be understood as restricting our claims of invention to any precise form or proportion of parts, or to any particular devices not essential to the principles of construction and mode of operation herein described,
