2 Claims.

My invention pertains to an improvement in binders.

An object of my invention is to provide a certain attachment which is attachable to a binder deck, and which will uniformly straighten out the grain to a position directly transverse to the binder needle, packing arms etc., so that when the bundles are tied there is relatively little waste of grain.

A further object of my invention is to provide a series of serrations having certain characteristics in which the grain is brought to its correct lateral position as it travels forwardly.

A further object of my invention is to provide an arrangement which can be adjusted for different lengths of grain, or which can be adjusted to correct the grain regardless of the angle in which it enters the binder deck.

A further object of my invention is to provide a properly tensioned arrangement wherein undue pressure exerted by masses of grain or other portions will cause resilient release of the straightenmg arrangement without destroying the guide and retarding effect thereof.

A further object of my invention is to provide this structure in a simple arrangement which can be readily attached to any standard binder deck and which is easily manufactured.

With these and other objects in view, my invention consists in the construction, arrangement, and combination of the various parts of my device, whereby the objects contemplated are attained, as hereinafter more fully set forth, pointed out in my claims, and illustrated in the accompanying drawing, in which:

Figure 1 is a sectional view taken substantially along the lines ll of Figure 3,

Figure 2 is a detail taken along the lines 2-2 of Figure 3,

Figure 3 is a plan view of Figure 1, and

Figure 4 is a detail taken along the lines 44 of Figure 3.

I have used the character In to designate the binder deck, character II the upper plate, characters l2 and I3 the rollers over which the elevating belts l4 and travel, and the character Hi the idling roller. Attached to the binder deck I0 is the bolt l! which includes a nut locked against the washer l8 and which bolt I1 is received within the slot IQ of the bracket 20. Attached to the end of the bracket is the vertical post 2| which includes the portion 22 having an opening 23 which receives the bolt 24 freely slidable therein. The bolt 24 includes the head 25 and the bolt 24 is attached to the keeper 26 by means of the two threadedly engaged nuts 21, and positioned between the nuts 21 and the member 22 is the compression spring 28.

The keeper 26 is attached at 29 to a substantially arcuate vertical plate 3|] which is of substantial length and height. The plate 30 is preferably made of thin sheet metal and attached thereto is a retarding and guide member 3| which includes a series of equally spaced and arcuate raised points 32 as well as the angular portions 33 merging therefrom as well as the further portions 34 which are attached to the plate 30. It will be noted from Figure 3 especially that the portions 3|, 32, 33, and 34 are preferably formed from one unit piece of sheet material which is attached as explained, Joining the arcuate raised portions 32 also are the portions 35 which are substantially at right angles to the plate 30. This structure then, provides a series of raised projections including the angularly sloping portions 33 and as shown in Figure 3 with the projections being gradually directed toward the central portions of the deck l0 and toward the usual needle 36', and packer arms 31 etc.

Attached at 38 (see Fig. 2) to the upper por tion of the plate 30 is a further flange 39 to which is attached the bearing 40 which bearing is adapted to rotatably receive the pin 4| which is retained by means of the cotter pin 42, the pin 4| being attached to the portion 43 which in turn is bracket in desired position. Now that the structure of my device has been explained, I shall explain the operation thereof.

As the grain which is cut by the sickle travels up between the travelling belts I4 and I5 it enters on to the deck at the approximate position 48 as shown in Figure 1 and then falls upon the deck l0. Due to the natural cutting action of the sickle on the binder, there is a tendency for the heads of grain to be projected forwardly, due to the drag effect, and it is necessary to straighten the grain so that it is directly lateral to the binding arrangement in the deck. As seen from Figure 3 the dotted lines 49 indicate the grain in its various stages as it passes across the deck Ill, and it will be noted that the heads of the grain first impinge against the upper deflecting portions 33. As the grain i traveling downwardly with respect to Figure 3, or down along the deck in, the succeeding portions 33 will have the tendency of gradually retarding the heads of the grain and bringing it to a lateral position as it approaches the tying arrangement.

As illustrated in Figure 3 the gradual approach of the grain stalks to the lateral position is shown, and each successive sloping portion 33 has the tendency of successively straightening each stalk as it progresses due to the retarding effect, and the rounded portions 32 permit the grain ends to wipe across these portions without an abrupt stopping action.

The curvature of the member 30 is such that the lower end is closer to the tying arrangement of the binder than the upper end, and as the mass of grain travels downwardly along the deck this has the added effect of carrying the grain inwardly toward the needle and points so that as a result the combined effect of straightening the grain and momentarily retarding it due to the projecting members as well as the curvature of the plate 30 tends to bring the grain to its true lateral position as well as its centered position, thereby preventing stray stalks from drifting across the deck I sideways, and in this manner the stalks are correctly positioned and concentrated.

For convenience in understanding the drawing in Figure 3 especially, the lower end of the deck is indicated by the character 50. The tensioned arrangement as shown in Figures 3 and 4 insures that when heavy masses of grain or bulky portions thereof reach the lower end of the plates 30, in the event that such portions would tend to jam the arrangement, the spring 28 allows a resilient release at this point so that the entire arrangement will pivot about the pin 4! with the lower end of the plate 30 being resiliently urged in the direction of the arrow 5|. This prevents clogging of the arrangement and insures that the grain is kept in its lateral position in spite of the effect of larger grain, massed grain etc. It will be noted that by loosening the bolt and nut arrangement I1 and 46 that the brackets 20 and 44 can be adjusted in either direction across the deck to accommodate different lengths of cut grain, or to provide for grain entering the deck at difierent angles.

For instance the bracket 20 can beadjusted to carry the lower end of the plate 30 inwardly toward the tying arrangement or outwardly therefrom to accommodate different grain lengths and so that the bundle will be tied at the center thereof. Also the bracket 44 can be adjusted in the same manner to carry the upper end of the plate 30 in either direction to form an increased or lessened arc to the plate 30 to accommodate grain which may fall on the deck at a steeper or lesser angle since this also will effect the angular position of the portions 33.

As a result the adjustment will take care of any length of grain, or other factors such as angle of entrance on to the deck, Weight thereof and the like.

It will now be seen that I have provided all of the advantages mentioned in the objects of my invention, with other advantages being readily apparent.

Some changes may be made in the construction and arrangement of the parts of my invention without departing from the real spirit and purpose of my invention, and it is my intention to cover by my claims any modified forms of structure or use of mechanical equivalents which may be reasonably included within their scope.

I claim as my invention:
