CLEMMA R. RANEY, OF CHICAGO, ILLINOIS, ASSIGNOR TO INTERNATIONAL I-IARVESTER COMPANY OF NEW JERSEY, A CORPORATION OF NEW JERSEY.

GRAIN-BINDER.

To all whom it may concern:

Be it known that I, CLEMMA R. RANEY, a citizen of the United States, residing at Chicago, in thecounty of Cook and State of Illinois, have invented certain new and useful Improvements in'Grain-Binders, of which the following is a full, clear, and

exact specification.

My invention relates to grain binders.

It has among its objects to make compact sheaves havingsquare butts and their bands so positioned that the sheaves are Well adapted to stand in shocks in the field and withstand vhandling. A further object of my invention is to make such sheaves automatically in such a manner that the heads,

butt and bands of the same are adjusted automatically under varying. grain conditions, whether operating in longor short grain, irrespective of the length of the grain and without the necessity for anyadjustment on the partof the operator of the binder, such as has been necessary hereto fore, the sheaves being automatically formed and the position of the bands thereon being automatically adjusted- I attain these objects by the provision of improved automatic mechanismcomprising a buttboard and headboard operatively connected to,-

gether in an improved manner, and autoinatically adjusted under all conditions by the grain passing over the binder deck as the length of the same varies, to adjust the heads v and butts of grain of different lengths and form therefrom sheaves of a compact character having their bands ac' curately positioned at the desired point intermediate their ends.

In the accompanying drawings I have illustrated three embodiments Which my invention may assume in practice. It is to be: understood, however, that the forms shown Specification of Letters Patent. Patented A11 21, 1917.

Application filed December 8,1913. Serial No. 805,230.

Fig. 4L is a detail end elevation of the latter;

Fig. 5 is a detail side elevation of a modified form of headboard;

Fig. 6 is a top plan view of a modified form of the construction shown in Fig. 1;

Fig. 7 is a detail of the adjustable connecting mechanism shown in Fig. 6.

Ihe construction shown, when broadly considered, comprises a buttboard, and a headboard, the buttboard being operatively connected to a moving part of the binder and operatively connected to the headboard in such a manner that the two are automatically maintained in a predetermined relation with respect, to the grain passing between them under all conditions irrespective of variation in its length, all changes in position of the head and buttboards being brought about by the grain itself as the latter varies in length.

In Fig. 1 I have illustrated diagrammatieally a binder of the usual construction, having a lower binder deck 1 and an upper binder deck 2. In the usual position upon this binder a butter board 3 I is mounted. As shown, this butter board is operatively connected to a moving part of the binder through a crank connection 4, the I action of the latter being to impart an orbital movement to the butter board in a well.- known manner. Carried upon the stubbleward end of this butter board is also a butter extension 5 of Well-known construction; this extension being pivoted to the butter board at 6 and to the machine frame through a link 7 in such a manner that as the butter board moves in its orbital movement the extension 5 acts upon the grain after it has been acted upon by the butter.

Carried upon the opposite side of the.

sheaf binding mechanism 8 from the butter board 3 is a headboard 9. This board is pivotally mounted upon an upstanding pivot 10 journaled in and suitably positioned on the peaked or stubbleward end of a diagonally disposed segmental bracket or casting 11 disposed parallel to the upper deck and fixed thereto at its upper end by any suitable means. Asshown, this board 9 is operatively connected to the butter board 3 through a connecting member or rod 12 ex.-

. gageinent with the teeth 19.

tending diagonally across the upper deck and having oneend fixed at 13 to the extension 5 on the butter 3; while itsother end is pivotally connected at 14; to an upstanding pin 15 formed on a pawl 16, which is in turn pivoted at 17 to an arm 18 extending substantially at right angles to the member 12 and movable with the headboard 9. This pawl 16 cooperates with a series of ratchet teeth 19 formed on the upper edge of the segmental bracket or casting 11 and moves with the butter board between stops 20 and 21 formed on the bracket, a suitable stop or lug22 being provided upon the member 18 to maintain the pawl normally out of en- 7 As shown in Figs. 1 and 2, the headboard 9 is fixed to the stubbleward end of the arm 18 and normally disposed in a plane substantially at right angles with respect to the oinder deck, and at an angle of substantially 15 with respect to the connecting member 12, a resilient connection being provided between the same and a bracket 23 having U-shaped arms 24 fitting over the ends of the pivot pin 10 and its upper arm rigidly attached to the arm 18 'at 25. This resilient connection is made to an extension or arm 26 projecting substantially stubblewardly from the rear of the bracket 23 at a point substantially between its U-shaped arms; a plurality of spaced lugs 27 being provided on this extension, in which is journaled an L-shaped holding member 28 positioned by a cotter pin 29. As shown, one arm of this memv ber. 28 is flattened to form a reinforcing strap for the headboard, and is bolted to the grain face of the latter at 30, while a coiled spring 31 extends around the other arm of the same between the lugs 27, one end of this springbeing positioned against the. grainward lug 27, while the other end extends out across the top of the headboard and through one or the other of aplurality of perforations 32 in a supplemental adjusting plate 33 carried on the opposite side of the headboard from the member 28 and secured thereto by one of the bolts 30 holding the latter in position. As shown, the headboard is also operatively connected to the connecting member 12 by a coiled spring 841 operatively connected at one end to the bracket 23 at a point adjacent the lower lug 27 and extending diagonally across the upper deck, where its other end is connected to the member 12 at a point intermediate the "ends of the latter and slightly toward the headboard end thereof.

-The operation of the construction shown in'Figs. l to 4 is as follows: l/Vheh there is no grain passing through the binder the parts will occupy the posltion shown 1n Fig.

1, the pawl being then disengaged from the ratchet teeth 21 and both the head and butt boards being unlocked. When grain is ter.

passed through the binder, however, due to the pressure of the same on the butter board, the pawl will be thrown into' engagement with the ratchet teeth in such a manner as to lock the butter board and cause it to form an effective adjusting agent as it is moved by its operating mechanism, the head board then cooperating with the butter boardin adjusting the grain flowing over the deck and being maintained in adjusting position by its connection to the butter board, though free to move outward at any time. When longer grain commences to come over the binder deck from the elevat ing mechanism, it is, of course acted upon by the butter board in the usual manner. The heads of this longer grain, however, strike the head board 9 and force the same outward with the result that the pawl 16 is automatically disengaged from the ratchet teeth and the butter board is also freed. Obviously, when this occurs, since both the head and butter board are free, they will separate to enable the longer grain to pass between the same, the butter board throwing the pawl into locking engagement with the ratchet teeth and the head board releasing the same alternately as the pressure varies in such a manner as -to insure eflicient adjusting and proper placing of the band. It is thus seen that the headboard moves outward with a step by step movement as the butter board moves outward, and the pawl travels over' the teeth 19, the boards yielding and forming substantial abutments alternately in such a manner as to accommodate the different lengths of grain and cooperating to maintain a predetermined relation to the butts and heads of the grain despite variations in'the length of the lat In other words, the headboard moves outward as the butterboard moves outward until the two boards conform to the increased length of grain, at which time they continue to cooperate to force together the heads and butts of the grain between them, in a manner heretofore described, the butter board being locked and the'sheaves being automatically adjusted with respect to the binder deck and binding needle by both the head and butter board in such a manner that their hands are always accurately positioned thereon at the desired distance from the butt irrespective of variations in the length of grain. Obviously, should the grain be too long to be handled by the headboard 9; as, for instance, when working in long grain, suchas' rye, Kafir corn or the like, this board will, after it reaches its ordinary rearward limit ofmovement when subjected to an additional pressure determined plied, will be moved downward by the spring to the position shown in full lines in Fig. 2. It is also clearly apparent that when the grain becomes still shorter, the spring 34 will act immediately to withdraw the headboard 9 toward its original or normal position shown in Fig. 1, swinging the arm 18 backward about its pivot without allowing the pawl 16 to engage until it again occupies the proper position for acting upon the grain then coming through the binder when it is again thrown in by the pressure on the butter board. It is also to be noted that when the headboard comes back, the butter board will also be brought in and that the two will continue to act in unison, moving toward or from each other as the grain varies in length, always pressing in the heads and the butts of the grain automatically, regardless of the length of the grain, and being actuated by the grain as it varies to effect their adjustment. r

In Fig. 5 I have, illustrated a modified form of the construction shown in Fig. 1, wherein, instead of using a headboard, which is free to move upward independently of the arm 18 connecting it to the buttboard, I have illustrated a rigid headboard, the construction being modified accordingly. As shown, the arm 85 in this construction also forms a strap 36 supporting the headboard 87, the latter being also connected to the member 36 by a spaced supplemental strap 38 in such a manner as to form a rigid construction only movable with the arm. Further. as shown in this construction, a depending lug 39 is formed on the ratchet or bracket member 40, to which is connected a downwardly extending strap a1 extending to the lower deck 42, to which it is bolted by a bolt 13 and adjacent which bolt it is provided with an extension 4-1, which acts as a support for the lower end of thepivot pin 45, cooperating with an inturned lip 46 on the lower end of the member 35 in forming a bearing for this member. As in the previous construction, the upper end of the pin 45 is journaled in the ratchet member 40, and a connecting rod 47 is connected between. a pawl 48 and the butter board, a spring 49 being interposed between the same. The operation ofthisconstruction will obviously be the same as that shown in Figs. 1 to 4, with-the exception that the board 9 will not swing outward when it reaches the limit of its travel.

In Figs. 6 and 7 I have illustrated a still further modified construction, wherein, instead of being used in connection with a butter board, my invention is adapted to use in connection with a gear drive butter of the endless apron type. In this construction the butter frame 50 is pivoted as usual at 51 on the binder frame and the apron 52 thereof is driven from a moving part of the binder,

a strap 58 pivoted on the frame extending beyond the end of the apron and connected to the upper binderdeck by a diagonally disposed spring 54, tending to maintain the same in its uppermost position. As shown, a headboard 55 in this construction is pivoted to the deck, being connected to the stubbleward end of an arm 56 pivoted intermediate its ends to the deck at 57 and disposed at an angle of slightly over 90 with respect to the headboard. The upper grainward end of this arm 56 is pivotally connected to a diagonally disposed link or rod 58, which, as in the case of the connecting member or rod 12 heretofore described, is connected at its lower end to the butter, in this instance, however, being pivoted to the strap 53 at 59. In. order that the headboard and butter may be automatically operated in this construction, I employ a threaded rod 60 pivotally connected at 61 to the deck and extending downward and forward substantially parallel to the rod 58. As shown, the front end of this rod 60 is threaded. for a substantial distance, as shown at 62. and the rod is connected through a U-shaped bracket 63 with the butter, the latter being in turn pivotally connected between the arms of the U as shown at 64: in such a manner as to permit it to move freely. Motion is transmitted to this butter mechanism, and therefore to the headboard, by means of a chain 65 operatively connected between a sprocket (36, operatively connected to the driving mechanism for the butter, and coii 'ierating sprocket (37 ournaled in the stubbleward end of the strap 53, av beveled gear (38 being journaled with the sprocket 67 upon the stubbleward end of the strap 53 and in a plane above the butter 52 and the threaded rod 60. This beveled gear 68 cooperates alter nately with a plurality of preferably rigidly connected spaced beveled gears 69 and 70 carried upon the rod 60 on opposite sides of the U-shaped member 63, acting to connect the butter and headboard adjusting mechanism to the operating mechanism of the former when the pressure on the spring 54 exceeds a predetermined amount. Obviously, the remaining operation of this construction will be substantially the same as that described in connection with Figs. 1 to 5, the beveled gear 67 being alternately thrown into engagement to shift the headboard and butter automatically in accordance with the variations in length of the grain.

It is to be noted that in my improvement the action of the head board and butter is entirely automatic, the parts being adjusted and locked and unlocked by the grain itself as the grain varies in length regardless of whether or not the machine is working on a side hill and without it being necessary for any sheaves to be properly adjusted or for the operator to pay any attention whatsoever to their position or adjust them by means of an adjusting lever.

It is further to be noted that not only do the boards adjust themselves in their outward movement to handle long grain, but that they are also automatically returned to their inner grain handling positions, wherein the heaa'fllioard normally acts as an abutment eoeperating with the butter. Attention is also directed to the fact that should it be desired to use the device in connection with excessively long grain, such as Kaiir corn or the like, in the form of my invention shown in Fig. 1, the headboard is also imtomaticaliy swimg upward by this grain without the necessity for attention on. the part of the ope 'ator.

'hile I have in this application specifically described three forms of my invention, it is to be understood that I intend to'include within the scope of this case such other modifications of the embodiments chosen for purposes of illustration as will be apparent to those skilled in the art and fall within the spirit of my invention.
