To all whom it may concern.-
Be it known that I, EARL G. VVATROUS, of Smiths Mills, in the town of Hanover, county of Chautauqua, and State of New York, have invented certain Improvements in Automatic Grain -Binders, of which the following description, in connection with the accompanying two sheets of drawings,constitutes a specification.
This invention relates to novel devices for gathering, compacting, and confining the cut grain of which the sheaf is composed preparatory to and during the operation of binding the same, to devices used in connection therewith for discharging the bound sheaf from the binding-table, and also to a new combination of the operative parts of a grain-biuder, whereby the tension may be wholly or partially applied to or withdrawn from the binding-twine as the exigencies of the binding pro cess may requlrel As my apparatus is susceptible of being applied or adapted to a great variety of grainbiuders, especially to different styles of knot or band tyers, I have not shown in the drawings any knot or band tying mechanism, and only so much of a binding-table as is necessary to elucidate my invention.
Figure 1 of the drawings shows the relative position of the several members of my apparatus at the finish of the stroke or throw which discharges the bound sheaf, in which position the machine remains at rest pending the accumulation of straw for the neXt sheaf. Fig. 2 shows the position of the same parts at the moment of tying the knot or of securing the sheafband. Fig. 3 shows an adaptation of the needle-arm to co-operate with the device provided to regulate the degree of tension applied to the binding-twine.
My apparatus as here shown is adapted to be used in connection with any variety of knotter,or band-tyer located beneath the bindingtable A. It consists of a needle-arm, E,
mounted on shaft D, which has a rotary reciprocating motion imparted to it from some part of the machinery of the binder, so thatit can oscillate from the position seen in Fig. 1 around to the position shown in Fig. 2, and back again. Needle-arm E has a projection,
L, to the extremity of which the link G is pivoted at v. This link connects with the discharging-arm M at u. The discharging-arm M is substantially of the shape shown, and is hung from the top of a bracket-arm, G, which is an upward projection from standard B. At the point non the discharging-arm the compressing-arm R is attached. This has a slotted prolongation, K, and through the slot R the set-screw N passes and screws into the discharging-arm. The slot R and set-screw N are provided as a means of adjusting the gap of separation between arm R and the needle arm E when they are in the act of compressing a bundle. To the compressing-arm R is affixed the compressing-spring E. This spring is so constructed and attached that normally it stands about asin Fig. l-that is, with its free end advanced a little ahead of the lower end of arm B, so as to engage with the accumulated straw a little in advance of the arm It. This, among other things, is to prevent the paying out of more binding-twine than will be taken up by the needle-arm in the act of binding.
The lower end of the discharging-limb M is bent back, as at O, as a provision forhanging thereto the foot J. This foot is pivoted to the discharging-arm at 00, and its position is controlled and regulated byaspring, s, in connection with the stop lug or pin 6. This construction permits foot J to be forced back into position shown in dotted lines in Fig. 2 as arm 11?. sweeps back over the straw accumulated to form the next sheaf.
The knotting apparatus is located beneath table A, directly under sheaf S, in Fig. 2.
The oscillating motion of the needle-arm E is imparted through shaft D,which is provided at the end opposite the one in view with a crankarm, which is connected by a pitman or otherwise with some driver on the binder.
I have shown in connection with the needlearm in Figs. 1 and 3 a tension device, or twine brake, as it may more appropriately be called, through which the cord passes from the twineball to the needle-arm, the action of which is controlled as to its time of operation by the motion of the needle-arm or of some other part of the binding machinery which has motion synchronous with that of the needle-arm. It consists of a pair of jaws, a and h, connected .by a bolt, f, which carries spring b, as shown,
the force of which is normally exerted to keep the jaws closed. The twine runs between jaws a and h,the outward lips of which are everted, so that the beveled edge U of arm B may easily enter between them and force them apart when the needle-arm makes its back-throw, and thus relieves the tension on the twine.
The machine operates as follows: The twine is carried from the twine-ball through the twine brake, thence through the various guides and eyes of the needle-arm to the knotter'at W, leaving the parts in position, as in Fig. 1, the jaws of the twine-brake being open, so that the twine may pay out freely as it is crowded back by the impact of the inflowing current of grain. The cut crop is carried up in the direction of the arrows and forced under and against twine g. until a sufficient amount is accumulated for a sheaf. Then at the proper moment the binder'is started. The instant the needle-arm commences its descent wedge U moves out from between jaws a and h of the twine-brake, thus permitting spring I) to act to close them and bind the bindingtwine between them. The degree of pinch or tension thus brought to act on the twine is regulated by the regulating-nut 70, which acts to compress or elongate the helical spring b. The amount of such tension, however, is sufficient, as arm E descends, carrying the twine around the sheaf in the usual way, to firmly compact the straw inclosed within its embrace and make a tight, firm, and compact sheaf.
It is not material whereabout between the needle-arm and the twine-supply the twinebrake is located, provided the time of its ac tion and intervals between its intermittent op erations are synchronous with the movements of the needle-arm. The improved results attending. upon the foregoing-described use of the twine-brake are these: Then the binder is at rest and the operation of gathering and compacting material for a new bundle is going on, which operation consists of forcing the cut straw against the binding-cord until a sufficiency for a bundle is accumulated,thetwine yielding and gradually paying out during such process, it is obvious that the more tension there is put on the twine the more power will be used to overcome such tension,in order to force the twine back to admit the straw, and this expenditure of power in this way is great and materially adds to the hard working of the machine, and such tension so maintained is wholly or mainly unnecessary and harmful, inasmuch as with some machines it compacts the strawinto a V-shaped mass, and
when the needle-arm carries the cord around the bundle it folds or laps the thin edge of the mass around upon itself, and often leaves a lank or hollow space in the bundle under the knot. When all or nearly all obstruction to the free running of the cord through its guideways, eyes, &c., is taken off, this does not oc our, and the straw is banked up in front of the twine in a symmetrically-homogeneous mass, which the encircling cord uniformly contracts and compacts.
To revert to the action of the needle and compressing arms, it may be stated that after the material of the bundle has been gathered and compacted, as before stated, and the binding mechanism started, as the needle-arm E descends, by means of connection G, the discharging and compressing arms are dragged down and advanced to meet and eo-operate with arm E. In this movement the compressiug-spring H acts by first engaging the straw and gradually yielding to the increasing pressure until mm B comes fully into position to accomplish its ofiice in compressing the bundle. If the spring H were not provided and arranged so to operate, it would result that when arm R did finally engage the straw and compress the same such compression, coming on so late in the process, would produce more slack in the band than arm E and the knotting devices could take care of. Meanwhile discharging-arm M has swept across the sheaf, dragging the discharging-foot J over the bun dle, as seen in Fig. 2, and has assumed the position shown in that figure. \Vhile the several parts are in this position the knot is tied and the cord severed. Then, by a reversed movement of shaft D,arm E recedes, and, concurrently, arm M and foot J advance. Foot J is thus promptly and energetically impelled against sheaf S, with the result of sweeping it free and clear of the binding-table, disengaging it from the current of infiowing grain, and delivering it to a bundle-carrier or onto the ground, as may be arranged.
To graduate the size of the bundle, the setscrcw N may be loosened and arm It swung in or out, to suit the object sought, when it can be tightened up.
A marked advantage accruing from this construction is the complete and effectual severance of the bound sheaf from the current of inflowing grain, a separation of from two to two and a half feet being secured.
Another advantage results from the fact that the binding and compressing arms and the compressing-springs are all hung upon or are attached to the same limb or member of the binder-frame, whereby it is possible to make IIO aforesaid pitman-connection a special advantage accrues in the avoidance of any sudden shock or blow to the sheaf at the moment of starting it from the table. By reference to Fig. 2 it will be seen that when the discharging movement is initiated pivot 1) moves in a direction almost at right angles to the line of motion of pivot it, thus starting the bundle very gently, its momentum gradually increasing until pivoto sweeps up around into position, where D, o, and a form a right angle, at which point its greatest force is exerted. By this time the sheaf is swept clear of the binding-table, either into a'repository or carrier, or else into the field. This characteristic of the delivery-stroke cannot be obtained when the binding or needle arm and the dischargingarm are geared together, as when so connected they approach and recede with uniform momentum and force.
The arrangement of devices shown in Fig. 3 is made with reference to a needle-arm which swings from a position beneath the bindingtable, the twine-brake being attached to some convenient part of the frame of the machine.
I therefore claim- 1. In a grain-binder, the combination of an oscillating needle or binding a'rm pivoted above the binding-table, an oscillating discharging-arm pivoted above the axis of the needle-arm, a compressing-arm attached to the discharging arm, and a pitman connecting said needle and discharging arms, substantially as and for the purposes set forth.

3. In a grain-binder, the combination of an oscillating needle or binding arm pivoted above the binding-table, an oscillating dischargingarm pivoted above the axis of said needle-arm and connected thereto by a pitman, and a compressing-arm adjust-ably attached to said discharging-arm, substantially as and for the purposes set forth.
4. In a grain-binder, the combination of an oscillating needle or binding arm pivoted to a standard above the bindingtable, an oscillating discharging-arm providedwith a springcontrolled tripping-foot and pivoted to said standard above the axis of the needle-arm, a pitman adj ustably connected to said arm, and a compressing-arm provided with a compress ingspring and attached to said dischargingarm, substantially as and for the purposes set forth.
5. In a grain-binder, the combination, with the needle-arm, of a twine-brake located in the path and plane of the same, and consisting of the jaws to and h, the spring I), for compressing said jaws together, and an adj ustingnut, k, for regulating the tension of said spring, said needle arm having a sharpened back adapted to enter the jaws a and h and force them apart as the needle-arm descends, for the purposes set forth, substantially as described.
6. The described discharging-arm provided with a discharging foot at its lower end and adapted to oscillate,substantially as shown, in combination with acompressingarm equipped with a compressing-spring fastened near its upper end, said compressing-arm being adjustably attached to the upper end of said dischargingarm, substantially as described, and for the purpose set forth.
