SPECIFICATION forming part of Letters Patent N0. 262,78 1, dated August 15, 1882.

Application filed November 17, 1881. (ModeL) To all whom it may concern:

Be it known that I, HARVEY R. INGLEDUE, a citizen of the United States, residing at Garroll, in the county ofGarroll and State of Iowa, haveinvented certain new and useful Improvements in Grain-Binders; and I do hereby declare the following to be a full, clear, and exing material; and the objects of my improvements are to form a square knot and tie the same close against the gavel, and while tying to maintain a steady uniform tension of the cord upon the gavel and to take up all slack in the same. I attain these objects by the mechanism illustrated in the accompanying drawings, in which Figure l is a front end elevation of the apparatus; Fig. 2, aplan view ofthe same. Fig. Sis anelevationoftheendoppositetheendshownin Fig. 1, showing the arrangement of wheels for operating the needle-arm and tying mechanism. Fig. at is a sectional View of the reciprocating cord-hook and its connection with the lever. Fig. 5 is a detail view of the loopers, cord-carrying arm, and reciprocating hook, showing one stage of the operation in forming the loops and the knot. Fig. 6 is a sectional side elevation of the apparatus. Fig. 7 is a detached view of the needle-arm shaft with spring and immediate connections, and Fig. 7 is a view of the form of knot tied by the apparatus. Figs. 8, 9, and 10 are detail views, showing the position of the cord in various steps of the operation. Figs. 11 and 12 are detail views of the holder and cutter and one of the loopers, respectively.

bimilar letters refer to similar parts throughout the several views.

The apparatus containing my improvements is of proper form to be conveniently attached to the ordinary harvesting-machine and connected with the running mechanism thereof.

The cord spool or reel may be supported ona spindle extending from the frame at a point,

a, Fig. 2, for instance, and be provided with a spring-tension device at a to prevent the cord from running too freely.

The grain is introduced on a platform of the usual form situated between the needle-arm and the mechanism for forming the knot, a slot being formed in the platform for the passage of the needle-arm.

The needle-arm A is secured to the end of shaft 1), which shaft is supported on brackets c 0, extending from the frame D, and around which is wound the spiral spring 0:. One end of this spring is attached to the bracket 0 and the other end to the shaft, as shown in Fig. 7. The oflice of the spring 00 is to throw back the needle-arm to its normal position after the cord is carried around the gavel.

Shaft b is operated at proper intervals by the action of a large mutilated cog-wheel, 1, through the smaller meshing cogs 2 and 3, cog 2 being mounted on the end of the shaft b and the, cog 3 on a short arbor extending at right angles from a bracket, 07.

Motion is communicated to the shaft 0 of large wheel 1 by proper connection with the operating mechanism of the reaper. The shaft 0 has bearings at one end in standards 1 Z and at the other in bridge or yoke 12.

The various mechanisms constituting the knot-tyingand cord-cutting devices are mounted upon the table or platform H, which is provided with a curved central depression, I, in which part of the loop-forming mechanism rests, and which platform is secured, as shown, to thetop of the frame D.

The device for forming the loops consists of two loopers, K K, consisting of tubular and slotted heads projecting at right angles from and carried by rotary and reciprocating stems or shafts 7c and Z from which heads project beveled armsff, asillustrated in Fig.12. The loopers are cast on the ends of shafts 7t and 1 which pass back through the plate 9, the shaft 76 to the standards I L on the back of the table, and the shaft 1 to wheel 7, carried on said shaft, and which meshes with wheel 6, carried on shaft 70. Plate 9' is provided on its face with annular flanges, which, with the plate g, form circular spaces or recesses separated ICO by a thin partition, t, into which circularspaces the loopers recede and in which they revolve, as hereinafter described. Cast on the back of plate 9 are sleeves j j, which form bearings, respectively, for the shafts of the loopersK K. These loopers are given both an intermittent rotary and reciprocating motion. A rotary motion from the large wheel 1 through intermediate mutilated wheel 4 and wheel 5 is communicated to shaft and wheel 6, and thence to wheel 7 on shaft of looper K. The small wheel 5 is mounted on the end of the shaft 7c, between two standards, I Z, which also are extended above wheel 5 to form supports for an upper wheel, 4, and shaft 0, which shaft carries the large'mutilated wheel 1, as

shown in Figs. 2 and 6.

Thereeiprocating motion is given-as follows: As thelooper-shafts are rotated a pin on each of the said shafts engages with a cam-slot,vor it may be a-groo\1e, 0, in-each of the sleeves-jj, and by these means-the loopers are carried forward as they are rotatedin opposite directions simultaneously. Theyare moved-back as they are rotated together, but in opposite directions from their first rotation, by the same means, and in the backwardmovement thepinin the cam slotor grooveis assisted by the'controllin g action of the spiral-sprin gs m m, woundaround the shafts of the loopers and located back of the sleevesj j. On receding the loopers rotate in opposite directions and twist the-cords to form the loopers, as: hereinafter described.

M is a reciprocating hooked arm or grasper located ina guideway, m and sliding in a. sheath, p,alsoin theguideway. The grasperis given a reciprocating movement through. the tubular loopers by meansof the lever r, and grasps and carries back the cord from a cordholder through the loops formed onand lying on the loopers at the proper time, and for the purposes hereinafter set forth. The sheath 1? isprovided with aslot on its upper surface, in which slides a pin on the grasper, which connects the grasper with one end of the lever 1". When the grasper is forced forward through the tubular loopers and seizes the cord held by thecord-holder P it is allowed by means of the above-described slot and pin on the grasper to recede within the sheath in its backward motion, and thus hold the cord between the end of the sheath and the hook on the grasper. The lever r at one end is pivoted to arm S, rigidly attached to disk t. Thisdiskis mounted on and rotated by shaft '73, which is supported by standards w and m". The standard 10 is a projection from bridge n; Shaft '21 is retated by means of pinion 8 meshing with mu tilated wheel 9, carried on shaft 0.

0 represents a shaft or rotating pin with a taperingpoint,used tohold theloops in position while being formed and to aid the binder-arm to take up the slack in the cord while the knot is being tied. It is supported at its heel by standard 3 and its point extends through the center of the thin partition 13 upon plate g, and out at and between the loopersK K, as shown in Fig. 5. Pin 0 is provided with apinion,10,

which engages with a wheel,1l, on the side of mutilated wheel 9, mounted on shaft 0, by which means it receives a continuous rotary motion.

The purpose of rotating the center pin, 0, is to prevent all friction and restraint of the cord while it is being drawn rapidly on the pin by the descent of the binder-arm, and while the knot is being tied. The great advantage accomplished by its use is to aid the binder arm in taking up all slack in the cord, so that the .sheafis tied as tightly as it is compressed; and

not only atightly-bound sheafis thusobtained, but a great amount of cord is saved, which otherwise-would be wasted in slack.

P is a device for holding and retaining the cord while the loops are forming, and it also cuts thecord and holds the ends after it is severed. It is provided with two arms, 3 and z. The lower arm,y,,.forms a shoulder around whiehthe'cordis. bent as it. passes from the holder 2 around the bundle'to the eye ofthe 'needle-arm, a-nd over which also the cord is again bent whenthe needle carries'itsend forward-to the loopers. The arm'z releases the free end: of the cord just after the grasper has seizedit, and on the. backwardmovement of the needle-arm it presses the cord against the knife 16, fixed to thetop of plate 17, thus severing it at the proper time and retaining the spool end against: plate. 17. The guards 14 guide the cord asit is carried forwardby the needle-arm, and while the loops. are. being formedby the loopers,-to keep the same'in line and prevent entanglement. This cord-holder P is pivoted to short projections on the plate .17, and to receive its swinging motion is provided with an arm, 18, and pin 19, connected with one end of the slotted bell-crank lever 20, as shown in. Fig. 11, which lever is pivoted at its angle to arm 21-, extending back from plate 9, and at its other endtoan arm, 22, sliding in away attached to brackets 23,.said arm 22 being provided on its outer end with pin 24, and which is reciprocated by means of the cam-groove formed by the cams 25, mounted on shaft 0. Before operating themachine the cord is firstvadjusted by carryin g its end from the spool through the tension device, then through the eye of the needle,,and then securing it back of arm 2 of'the cord-holder against plate 17, as shown in Fig. 1.

The operation of the machine is then as follows: The grainpasses over the needle in the direction of the arrow toward and under the loopers and against the cord, carrying the cord with it, the tension of the cord serving to partly form thesheaf. The needle-arm now ,rises' through the grain, drawing the cord tighter around the sheaf and carrying the cord directly below the loopersandvagainst the partition i, and under the revolvingcenter pin, 0, asshown in Fig. 8. While this is being done the loopers are extended outwardly to their farthest-extent, with their beveledarms f pointin g upward. The said beveled-arms prevent the cord from being carried back and on the upper side of the loopers as the needle-arm advances. The loopers now begin to revolve toward each other, and when they have performed a quarter-revolution they are retracted, by means already described, to within the recesses h h, bending the cord behind them. The loopers, continuing to revolve, twist the cords around them, forming thereon two separate loops, as shown in Fig. 9. The loopers are now carried outward, and when they reach their farthest outward movement and have completed an entire revolution the grasper M is carried quickly forward through the heads of the loopers and grasps the end of the cord retained by arm 2 of cord-holder P, as also shown in Fig. 9. The cord-holder at the same time releases its hold of the cord and the grasper recedes within its sheath,thus firmly holding the cord, and both sheath and grasper are then carried back through the loopers. At this moment the needle-arm, which has in the meantime remained in the position shown in Figs.5, S,and 9, moves backward and draws the cord from 0d the heads of the loopers through the slots in the same and onto the revolving center pin. The loops are then quickly tightened on the center pin, all slack in the cord being taken up thereon by the backward movement of the needle-arm, as shown in Fig. 10, which also at the same time withdraws the opposite end of the cord from the grasper. As the cord passes off from the revolving pin the knot is'tied tightly upon the gavel. As the needle-arm falls back to its lowest position it carries the cord back of the arms 2 and y of the cordholder P, which then close upon it, 2 pressing the gavel end of the cord against knife 16,

- which severs it, while the spool end of the cord is at the same time retained,ready for binding the next sheaf.

Having thus described my invention, what I claim, and desire to secure by Letters Patent,

1. The loopers provided with arms having beveled faces,in combination with a plate having circular recesses formed on its face, into which the said loopers are withdrawn and revolved by suitable mechanism in opposite directions, substantially as described.
