GRAIN-BINDER.

SPECIFICATION forming part of Letters Patent No. 419,154, dated January '7, 1890.

Application tiled November 20, 1888. Serial No. 291,373. (No model.)

T0 @ZZ whom t may concern.:

Be it known that I, LEWIS MILLER, a citizen of the Unit-ed States, residing at Akron, in the county of Summit and State of Ohio, have invented certain new and useful Improvements in Grain-Binders, of which the following is a specification.

My invention relates more especially to that class of automatic cord-knotting grain-binders exhibiting the following characteristicsviz., a slot in the breast-plate through which the cord passes over a supporting-linger normally extending athwart the slot, but movable laterally and intermittently to clear the passage for the cord, the sup portin g-iin ger being mounted on a recessed foot carried by an elbow-lever pivoted on the frame and vibrated by a cam on a cam-and-gear wheel, a knotter rotating once during each operation on an axis substantially perpendicular to the breast-plate over the slot and foot and stopping with its jaws pointing outward relatively to the line of the slot, and a cord-holder rotating intermittently to carry the cord into suitable relations to the bridge straddled byV the knotter-jaws and to the knife which cuts the cord as theknot is formed.

rlhe objects of my invention are to simplify the construction and increase the efficiency of the apparatus, which ends I attain by certain novel organizations and combinations of instrumentalities hereinafter specically designated.

My invention contemplates the embodiment of these improvements with the most complete apparatus of the present day.

The accompanying drawings represent so much only of an automatic cord-knotting grain-binding apparatus as is necessary to elucidate the subj ect-matter claimed with my improvements embodied therein. Some of these improvements maybe used without the others and in apparatus differing somewhat in details of construction from those shown.

Unless otherwise indicated, the parts hereinafter referred to are of well-known construction.

Figure l is a front elevation showing the parts in the attitude assumed (with both strands of cord in the holder) before the knetter begins to rotate; Fig. 2, a rear elevation. showing the same parts and attitudes as Fig. l; Fig. 3, a grain-side elevation, partly in section; Fig. 3, a detail section showing the overhung bridge or cord-guide bar behind the eye or enlarged opening at the termination of the cord-slot; Fig. 4., another grainside elevation with the knetter and its spindle removed to show the cord-h older more clearly; Fig. 5, a stubble-side elevation, partly in section, showing the side of the elbow-lever and cord-holder opposite that shown in Figs. 3 and 4, with the elbow-lever and holder-actuating pawl retracted; and Fig. 6, a similar view with these parts advanced. Fig. '7 representsa sectional plan showing the relation of the cordsupporting finger, knotter, holder, and cord just as the knot is being stripped from the jaws; and Fig. 8, a similar view showing the relation of these parts just before the strands are cut. Fig. 9 is a detail view, similar to that shown in Fig. 2, of the knot-ter-frame and holder. Fig. 10 is a detail View, similar to that shown in Fig. l, showing the cord-supporting linger, overhung bridge or guide-bar, and cordholder, with the cord carried and held at its lowest point thereby. Fig. 11 is a detail sectional plan showing the relations of the cordholder, slot, and foot, with its supporting-finger and recess in the most advanced position of the foot; and Fig. 12, a similar view of the same parts in their normal or retracted position. Fig. 13 shows a grain-side detail elevation, similar to Figs. 3 and 4., of the rotary cordholder disk and its oscillating springclamp or holder-shoe, illustrating the devices for adjusting the pressure of the clamp. Fig. 14 shows a similarl View of the cord-holder, clamp, elbow-lever, foot, and overhung bridge, showing the relation of the parts with the strands severed and the new strand in the holder. Fig. 15 shows a similar View with the foot advanced and the double strand held down on the bridge by the holder just before the knife cuts, and Fig. 1G is a detail viewof the cord-holder-actuating pawl detached.

In this instance I call the grain side of the machine the forwardf7 inner, or left-, and the stubble side the realy outer, or right7 side. The front of the machine is that side next the horses, and the other side the rear.

IOO

A driving-shaft a., mounted and driven in usual ways, carries an ordinary cam-and-gear wheel A and discharging-arms A A2. The bracketframe or knetter-frame B has a pipebox bearing b at its upper end encircling the shaft a. The knetterframe is forked or arched, so as to leave a central opening, its legs h b2 being provided with laterally-proj ecting feet secured to the breast-plate @,which is provided with a cord-slot c. This slot is shown as having a straight front wall back to a point just within the sweep of the knetterjaws, where it is deflected laterally and forwardly, terminating in an eye or enlarged opening c2. The rear wall of this slot curves forward slightly within the sweep of the knotter-jaws, forming a guide-nger c', which extends athwart the slot and forms the inner or grainside wall et the enlarged opening c2, above mentioned, in which the slot terminates, the longer axis of which opening lies ata right angle to the front wall of the slot, or nearlyso. The front branch or leg b of the knetter-frame, it will be observed, Figs. 7 and 8,li es close to but in front of the front wall of the slot,while the rear leg b2 is secured to the breast-plate beyond the end of the slot, but in the same line.

The knetter D, which is shown of the usual tyingbill pattern, has a shaft CZ, mounted in a pendent bearing b3 on the bracket-frame, and carries abevel-pinion d on its upper end, meshing with sector-teeth a on the cam-andgear wheel A. The lower jaw d2, in this instance, .is the fixed one. The upper jaw d4 is pivoted to move vertically relatively thereto and provided with the usual friction-roller d5,- spring d, and actuating-cam cZ7on the knetterbearing.

The knott-er-spindle, it will be observed, is practically perpendicular to the breast-plate in advance of the front line of the slot and overl the .forward en d o f the enlarged eye or opening c2. The knetter-jaws, Figs. 7 and 8, preferably normally standv pointing slightly outward and backward relatively to the slot, being' so organized as to make a single revolution at each operation orknot-forming an d then stop. j

` An elastic or yielding overhanging bridge or guide-bar E, Figs. 3, 3, 4, and 7, is shown as securedat one end on an upright post e on the breast-plate, as extending backward above and parallel with the breast-plate, and within the sweep of the knetter-jaws, which straddle it during the latterpart of their revolution and sweep the overlying strands therefrom as they are out. on the rear end of this bridge or guide-bar serves te prevent the strands escaping' prematurely therefrom.

A cam-guide f on the cam-and-gear wheel A`acts ena friction-roller f on an elbow-lever F, vibrating on a pivot f2 onl the knetterframe B. This elbow-lever is shown as oscillating on the outer or stubble side of the knetter-frame in a plane parallel therewith,

the knetter-frame.

A hook or shoulder e but transverse to the line of the cord-slet c, and ascarrying a cord-guiding foot G, Figs. 11 and 12. This foot terminates at its inner front corner in a cord-supporting finger ertoe g, extending laterally athwart the cord-slot,

and in such relation thereto that in its nor` mal or retracted position it extends entirely across theslot and bars the passage of the cord. Vhen in its advanced position, however, the strands slip past the heel g into the recess g2 in the foot, and thus pass into the eye c2 of the slot. The front edge of the toe is bent down so as to form a flange g3, which overlaps a corresponding upturned flange c3 on the rear line of the cord-guiding finger c of the breast-plate, Figs. l and 10, the effect of which is te prevent any possibility of the cordv working beneath the toe into the eye c2 until the toe moves out of the way.

The cord-holder consists of a disk H, provided with cord-receiving notches h on its periphery and mounted on a shaft hf on the knetter-frame. Figs. 7 to 1l show this disk as practically perpendicular to the breastplate and parallel with the knetter-spindle. It is intermittently turned at suitable intervals by means of a ratchet-wheel H on its outer side, actuated by a pawl I, rocking on a pivot t' on the elbow-lever and upheld by a spiral spring i', *Fig; 1G. The head t2 and shank a of this pawl are connected by a screw te adjust the pawl properly relatively to the ratchet-teeth, which adj ustment'is important to insure accurate co-operation of the pawl and holder. A detent-spring h2 prevents backward movement of the ratchet.

The cord-clamp, Fig. 13, is shown as consisting of a bell-crank arm J, trough-shaped and curved at bottom to encompass the holderdisk H, and rocking vertically on a pivot j on A set-screwj on the upper end of the holder-shoe J varies the pressure of a spiral spring f, interposed between the holder-shoe and frame, and th us regulates the pressure of the clamp on the disk, and consequently the bite on the bindingcord.Y

A knife K is .fixed on the foot G, near the forward edge of its hinder part, its front edge being blunt, curved, and sloping backward, Figs. 14 and 15, to-slide readily under the cord, while its rear edge is sharpV and inclined upward and forward, so as to make a sliding cut on its backward stroke. y

The other parts of the mechanism, being well known, need not be described.v

The apparatus operates as follows:` The binder-arm rises through the cord-slot, laying a strand of the cord over the cord-supporting toe g, which lies athwart the slot, and over the nose of the knetter into one of the notches h of the cord-holding disk, Figs. 1, 2, 3, 4, and 7, and then retracts, leaving the cord fast therein. After the gavel is formed the binderarm again rises, laying the second strand of' cord in the same position as the former one. The sector-teeth a en the cam-and-gear wheel A then mesh with the pinion d of the knetter,

and the latter begins to turn in the direction of the hands of a clock, the jaws passing under the strands, as usual, (see Fig. 3,) and sweeping them to t-he front. Simultaneously with this movement the foot advances from the position shown in Fig. 12 to that shown in Fig. 11, the cord-supporting toe g moves to the front of the line of the cord-slot, and the strands slip over the heel g into the recess g2. The effect of this movement, obviously, is to slacken the strands and thus give up cord to the knotter during the latter part of its rotation. As the elbow-lever carrying the foot advances, the pawl I earried by it rotates the cord-holding disk H in the direction shown by the arrows in the drawings and carries the strands downward and forward from the position shown in Figs. 3, 4, 7, 12, and 14 to that shown in Figs. 8 and 15. The forward movement of the foot carries the knife K in front of thestrands. At the same time the latter are carried down` ward over and in front of the shoulder or hook e on the cord-guide or bridge E. (See Fig. 15.) The knotter continues its rotation, while the holder and foot remain still in their advanced position. As the knotter reaches the front line of the slot and moves backward, its jaws open and straddle or embrace the strands lying on the cord-guide E, which is made slightly elastic to accommodate the passage of the jaws, as well as to compensate slightly the strain on the strands. The iixed jaw of the knotter in this instance passes under the bridge or cord-guide, while the movable one passes over it, and the strands thereon are caught in the jaws in the usual way. The shoulder e on the cord-guide prevents the strands from slipping off it, and

the parts assume the relation shown in Fig. 8, which draws the strands well within the jaws. The latter now stop while the foot retracts, and the knife cuts the strands in front of the holder-disk. The strand connected with the binder-arm still, however, remains clamped at the back of the holder, as usual. (See Figs. 5, 7, and12.) The continued backward movement of the foot causes the front wall of its recess g2 to strain on the cut strands, tying the knot tightly and pulling it from the jaws. The operation above described is then repeated.

The mechanism, it will be observed, under my organization is compactly and conveniently arranged in the arch or space between the legs of the knotter-frame, and all the parts are driven directly from the cam-andgear wheel Without superfiuous connectinggearing. The cord-supporting toe and recess elfectually prevent the escape of the cord, insure its being properly held and guided, yield the required slack cord to form the knot without breaking the cord, and strip the knot from the jaws. The bridge or cord-guide with its shoulder presents and retains the strands in proper relation to the knotter and holder, while the latter by its revolution carries the cord past the rear line of the knotter-spindle and lays it well on the jaws of the knotter.

The construction of the arched or forked knotter-frame with its feet on the front side of the cord-slot and the arrangement of the knotter-spindle and holder-disk axis in front of the plane of the slot enables the binderarm to lay the cord close to the knotter-spindle, and yet leaves the mechanism readily accessible. The rocking arm or clamping-jaw of the cord-holder, it will be observed, is pivoted well back of the line of the cord-slot, so as to leave plenty of room for getting at the mechanism.

The elbow-lever, which carries the cordguiding foot, knife, and the actuating-pawl of the cord-holder, rocks on a pivot transverse to but just below the actuating-shaft, slightly behind the axis of the knotter-spindle and the line of the cord-slot, and the elbow-lever itself vibrates in a vertical plane transverse to the line of the cord-slot back of the knotter and cord-holder, while its foot extends forward underneath the knotter, thus keeping the arm well out of the way of the knotter and cord. The springs are arranged out of the path of the cord to avoid liability to entanglement therewith.

I am aware that some of the above-described result-s have been attained by others as well as by myself in various ways. I am also aware that much of the mechanism herein described is shown in application for Let-- ters Patent of the United States tiled by me April 27, 1886, Serial No. 200,321, and in Letters Patent No. 410,427, dated September 3, 1889. I therefore limit my claims herein to the organizations and combinations hereinafter specifically designated.
