GRAIN-BINDER.

SPECIFICATION forming part of Letters Patent No. 234,372, dated November 9, 1880,

Application filed November 17, 1879.

To all whom t may concern Be it known that I, WILLIAM H. PAYNE, of Sandwich, in the county of De Kalb and State of Illinois, have invented a new and useful Improvement in Grain-Binders, which is fully described in the following specification, reference being had to the accompanyingdrawings, in which- Figure l represents a side elevation of a grain-binder embodying my improvements; Fig. 2, a bottom plan ot' the revolving graintable detached; Fig. 3, a plan view of the bed or support for the grain-table; Fig. 4, a vertical section through the table and support, the bindingarm being depressed and the twisting mechanism in position for forming the twist in the band; Fig. 5, a detail section taken on the-line .1; x, Fig. 2, the mechanism being shown in idle position; Fig. 6, an end elevation, on an enlarged scale,`ot` the twister, cutter, and that portion of the grain-table to which they are attached; Fig. 7, a perspective view, on a similar scale, of the twister, cutter, and vibrating frame to which they are attached, Fig. 8, a perspective view of the peculiar pinion on the grain-table, which operates the crank-shaft to vibrate the binding-arm at the properintervals 5 and Fig. 9, a detail View, showing a portion of the band and the twist which secures it around the bundle.

My invention relates to a grain-binder which is intended to be used in connection with a harvesting-machine wherein the grain is delivered to the binder intermittingly or in gavels, instead of in a constant stream.

The invention consists, mainly, in the combination ot' a bed or support provided with rack-segments, a revolving grain-table, a binding-arm mounted in the table, and a crankshaft provided with a pinion, the several part-s cooperating as hereinafter specified.

The invention also consists in certain devices and combination of devices whereby the required intermittent vibration of the bindingarm is effected as the grain-table revolves. y

The invention also consists in certain pecu liar band-fastening devices, whereby a peculiar twist is formed in the band-wire.

All of these parts will be hereinafter more fully described, and will be particularly deiined and pointed out in the claims.

In the drawings, A represents the bed or support for the grain-table, and is shown in the drawings of a circular form. The graintable Bis also of a circular form, and is mounted by any suitable pivotal support on the bedpieceAin such manner that it may be revolved freely. The bed-piece A is secured to the framework of the harvester by any suitable means, and in such position as is required by the delivery mechanism employed in order to eii'ect the suitable delivery of the gavels upon the table. It is not necessary to describe these devices more particularly here, as they will be readily understood by those familiar with grain-harvesting machines.

Il`he bedAis provided with an upright flanged rim, a, running around its outer edge. A second upright iiange, A', is arranged some distance within the outside rim, and is also circular in form. In the upper edge of this latter ange is a long cam-depression, Ia', and in the side thereof, just at the commencement of the former depression, is a short recess, a2. A driving-shaft, O, is mounted in suitable bearings on this bed, andis provided with a pinion,

c, arranged within the iiange A. On the rim of the bed-piece, near the shaft C, is a short gear-segment, D, and on the other side of the rim, but not quite halfway round, is a similar segment, D', while between the two is a circular rack, E, attached to the rim opposite to the depression a in the flange A. The rack E is on the inside ofthe rim, and projects above it, being inclined at each end, so as to vanish at the rim, as shown in Fig. l of the drawings. It is also beveled er tapered at each end, and at the finishing end is cut away so as to form a notch, c, in the upper part thereof, as shown in Fig. 3 of the drawings.

0n the bottom of the tableB is a circular rack, t

b, with which the pinion cen gages, thereby providing means for the revolution of the table. An upright standard, b, is mounted on the table near one side of the latter, and the bandspool b2 may be supported on the top of this l standard, if desired. The binding-arm F is pivoted to this standard, being shown iu the drawings arranged in a slot therein.

A pitman, G, is attached by a ball and socket or other suitable socket to the end of the bindingarni behind its pivot, and the IOC lower side of the grain-table.

lower end ot' this pitinan is attached to the crank-pin of the crank-wheel g, which is attached to the inner end of a short shaft, g', mounted on suitable bearings attached to the A pinion, H, is also fixed on this crank-shaft and arranged so that its path will bc over the segmental gears D D. This pinion is mutilated, having toothed sections h on opposite sides thereof, between which are arranged studs or projections?.

A small naine, I, is mounted by pivotal supports in pendants I', extending downward from the under side ot' the table between the rim and inner tiange. This trame is arranged to vibrate vertically on its pivots, which are located near theinner end thereof. Two arms or pins, t', project from the inner end ot' the frame and rest on the flange A', which serves as a guide to control the position and movement of the swinging` trame by means of these guiding-pins. The swinging traine extends outward over the space between the rim and iiange A', its outer end projecting' somewhat beyond the former, as shown in Fig. 4 ot' the drawings. The twister-hook K is mounted in this swinging frame, its shaft 7.'. being arranged loosely in its bearings to permit asliding or longitudinal movement lengthwise of the frame and in a direction radial to the revolving table. The twister-pinion L is fixed on the shaft 7.', and is arranged so that its path will be over the rack E as it is carried around by the revolution ot' the binding-table. This pinion is provided with flanges Z l on each end, the former of which is cut away to present a short straight portion, Z2, on the side ot' the shaft L opposite to the point of the twisterhook. A spring, k, is attached to the swinging frame back or inside of the twister-pinion, and arranged to press upon the back ot said pinion, thereby causing the twister-shaft and twister to be thrust outward to their fullest extent in their normal position. The outer end of the swinging frame is cut away to form a shoulder, fi', in which a notch, t2, is made eX- tending inward below the twister and in the direction of its shaft.

A bent arm orlever, M, is pivoted to the swinging frame, as shown in Fig. 7 of the drawings, its outer end being bent around in front of the frame, in bell-crank form, in such position that its outer extremity may be brought up against the face of the shoulder i. This outer eX- tremity of the arm is beveled to form a biting or clamping edge, m, which is adapted to tit the notch t2 in the shoulder t', for the purpose of clamping the band-wire. On the upper side of this end of the arm there is also a euttin gblade, N, which projects sufficiently to pass a short distance over the ripper face ofthe shoulder t', against which it cuts when the arm is closed. The inner end of the arin M is bent backward and inward until it strikes the outer face of the flange A', being provided at its inner extremity with a friction roller, fm,

which runs in contact with this ange, and thereby controls the position and movement ot' the clamp and cutter.

A recess, b3,is made in the edge ot' the binding-table at one side thereof, directly underneath the bindingarm, through which the binding-arm passes as it descends to place the band around the bundle, and a notch, b4, is made in the inner edge of this recess,in which the ba ntl-wire O is received, as shown in Fig. 4 of the drawings.

The operation of this grain-binder is as follows: The binding-arm being raised or open, as shown in Fig. l ot' the drawings, and the wire run down in the notch b4 in the recess in thc edge ot the table to the vibrating frame I, to which it is secured by means of the clamping device above described, a gavel is delivered upon the table, carrying back the wire underneath the binding-arm. The drivingshaft is rotated by suitable connection with the gearing ot' the harvester, and thus revolves the grain-table, thereby carrying the table, with the gavel thereon and binding mechanism attached thereto, around away from the delivery devices. The bindin g-arin reinainsin its raised position until the pinion H is brought to the` rack-segment D, when one ofthe stops hf, striking against the end of the rack, turns the pinion into engagement with the rack, thereby rotating the crank-shaft and Aclosing the bindin g-arm through the action of the pitinan. The closing of the binding-arm carries the wire down around the bundle through the recessin the edge ofthe table, thereby placing another stra-nd in the notch bi, which is carried down by the side of the tirst strand by the bindingarm as it descends to the position shown in Fig. et of the drawings.

lt is evident that there are now two strands of wire between the end ofthe vibratin g twisterframe and the notch in the table. About as soon as the binding-arm is closed the twisterpinion is brought into engagement with rack E, which is embraced by the tianges on the pinion. As this rack increases in thickness the pinion is drawn back as it starts into engagement with the rack, carrying the twisterhook back with it, which, at the commencement ot' rotation, catches the two strands ot wire between the twister-frame and the table and pulls them both back with it. At the same time the twister-frame is raised at its outer end by the pinion riding up on the rack, as shown in Fig. 4 of the drawings, thereby accoinmodating the backward pull of the two wires and pulling wire at the same time from the spool.

The depression in the iiange A permits the guide-pins t' to drop to allow the frame to be vibrated,-as described. The position of the parts at this moment is shown in Fig. 4 of the drawings, and it is evident that from the clamp to the twister-hook are two strands of wire lying along the upper face of the twister-frame, and that these saine two strands are continued from the hook to the edge of the table.

The continued revolution of the table carries the twister-pinion forward in engagement with its rack, thereby forming the twist in the ends of the wire for the purpose of securing the band around the bundle, and this twist is of peculiar form, for it is evident from the above description that double strands are twisted together, thereby forming a twist of four wires, instead of two, in the usual way.

At the last revolution of the twister the clamp is opened by the inner end of the clamparm dropping into the recess in the side of the iiange A', thus releasing the end of the bandwire which it had held, and allowing the main wire extending upward from the binding-head to slip in to the cla-mp, which im mediately closes, thereby securing the wire, and at the same time the cutter severs it on the upper side of the frame, so as to release the bundle.

As the twister-pinion passes off from the rack the frame is turned down again by the guidepins leaving the recess in the ange A', the twister is thrown forward by the action ofthe spring, the wire slips oif the end of the twister, and the bundle may be discharged.

The rack and twisterpinion are so constructed and timed that the rotation of the latter will always cease with the twister-hook point projecting upward, as shown in Fig. 5 of the drawings, and as the pinion is thrown forward and the vibrating frame lowered the straight edge Z2 oi' the flange Z rests upon the rim of the support below, as shown in Fig. 5 of the drawings, thereby locking the twister in this position.

rlhe continued revolution of the table soon brings the pinion H into engagement with the rack D', thereby rotating the crank-shaft in the direction to pull down the pitmau and open the binding-arm, when, of course, it is ready to receive another bundle, and the operation is repeated.

It will be readily understood that the parts described must be arranged with reference to the delivery mechanism ofthe harvesting-machine, so that the binding-arm will be opened when that side of the tableis presented to the y delivering devices, and will be closed and the band secured after the binding-arm has been carried around away from the point of delivery. This is a mere matter of arrangement, which will be readily understood so as to be carried out by any one familiar with the construction of harvesting-machines.

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