GRAIN-SCATTERING-PREVENTING'DEVICE FOR GRAIN BINDERS.

Application filed June 24, 1922. Serial No. 570,563.

To all whom it may concern:

Be it known that I, OSCAR E. PAULUs. a citizen of the United States, residing at Harvard, in the county of Clay and State of Nebraska, have inventedcertain new and useful Improvements in Grain-Scattering- Preventing Devices for Grain Binders, of which the following is a specification, reference being had to the accompanying drawings.

The purpose of the present invention is to provide an improved device of this character adapted for attachment to a grain binder, preferably to the top of the upper deck of the binder, to insure preventing scattering of the grain and to make a more perfect bundle, regardless of the varying height and thickness of the grain in the field.

Very often grain grows short, and during theharvesting of the grain, the short grain as it leaves the canvas, travels on the lower deck of the binder at angles. In other words the heads of the grain become directed downwardly, owing to the shortness thereof, and not only cause irregular bundles, but cause the grain to scatter and become wasted, especially when the binder is turning corners. Hence another purpose is to practically eliminate the waste or scattering of the grain, and to insure uniform bundles.

In fact still another purpose is to provide a device of this kind, with means to retain the grain especially the heads thereof straight as it comes from the canvas to the packers, while the butter canvas forms the bulk of the bundle.

A further purpose is to provide a grain scattering preventing attachment including a supporting structure mounted upon the lower rail of the upper deck and provided with a yieldable arm projecting down from the upper rail of the upper. deck in the path of the grain, so that as the grain leaves the canvas, it becomes straightened and held even or uniformly as it travels toward the .packers, thereby holding the grain in position and insur ng more unlform bundles,

especially when the binder is in the act of turning corners, at which time the grain heretofore scatters and'becomes wasted, very often being thrown or lost from-the lower deck of the binder.

the invention, any desired modifications of detail and desired proportions may be made in the apparatus according to circumstances.

The invention comprises further features and combination of parts, as will be hereinafter set forth, shown in the drawings and claimed.

In the drawings Figure 1 is a view in perspective of a portion of a grain binder, showing the improved grain scattering preventing device as applied, illustrating the grain straightening finger or *arm as protruding down from the upper edge of the upper deck;

Figure 2 is a sectional view on line 22 of Figure 1;

Figure 3 is an enlarged detail perspective view of the grain scattering preventing device as detached from the binder.

Referring to the drawings, 1 designates the lower deck of a conventional form of grain binder, and which is provided with an abutment 2 for the grain. Arranged and spaced in proper position above the lower deck of the binder is the upper-deck 3, and obviously the grain after it is harvested, leaves the canvases 4:, and passes down between the upper and lower decks of the binder, where the packer arms 5 operate to from the grain into closely packed bundles. The lower rail of the upper deck is provided with the usual yieldably mounted fingers or check springs 6, which act materially in retarding the grain, in fact prevents a too rapid passage of the grain over the lower deck.

The grain scattering preventing device comprises a supporting frame or structure consisting of the arms 7, which are secured by suitable bolts or the like 8 to the lower rail of the upper deck. These arms 7 are disposed so that they converge from the lower rail toward each other and are held in such relative positions by means of the transverse brace 9, which is riveted, bolted, or otherwise secured to the arms as shown at 10.

The upper portions of the arms 7 .beyond the brace 9are bent or formed upon themselves to cause bearing sleeves'll 'to be formed. The extensions of the arms beyond the bearing sleeves 11 are disposed in parallelism to and are riveted'to the arms as at 12. These rivets also pass through an additional reinforcing brace 13, to insure a rigid structure.

'The extensions of the arms beyond the rivets are bent to assume angular formation as shown. These angular formed extensions 14 have parts 15 which are in parallelism to the arms 7 and are engaged under the upper deck of the binder, so that the upper portion of the upper deck; may engage between the angular extensions and the arms, thereby holding the supporting structure or frame to the upper deck.

A suitable bolt 16 engages through the axially aligned sleeve bearings 11 and is provided with a nut 17, to hold the bolt in position. An oscillatory member provided with a lateral arm is provided. This oscillatory member 19 comprises the long arcuately formed arm 20 and a short arm 21. The long arm assumes a substantially obtuse angle to the short arm. However throughout its length the long arm is curved, and extends downwardly, whereby its extremity may rest or engage upon the sur face of the lower deck. A tensioned coil spring 22 is connected at 23 to the transverse brace 9, and is in turn connected at 24 to the short arm 21-, thereby retaining the extremity of the long curved arm 20 constantly in contact with the surface of the lower deck, especially when the grain is being packed to form a bundle. However after the bundle has been properly formed and tied it may be automatically discharged inthe well known ordinary manner. The oscillatory element has a projection 25, which has a sleeve bearing 26, through which the bolt at the top of the holding frame or supporting structure engages, thereby pivotally supporting the element, so that the curved arm 20 will constantly rest upon the lower deck as a result of the tension of the coil spring.

Heretofore in the operation the grain as it leaves the canvas would very often assume angular positions, with the heads thereof directed downwardly as it travels on the lower deck. This irregular position of the grain, during the packing of the bundles by the packers, would cause irregular shapes of bundles, and therefore hinder the proper tying. However with the present device, when the grain travels downwardly with the heads thereof foremost, the grain contacts with the arcuate arm of the oscillatory element, and the grain is straightened, arranging and packing the grain into uniform'bundles, hence preventing scattering and the waste of the grain during the harvesting season, especially when the binder is in the act of turning corners.

The invention having been set forth, what is claimed is 1. The combination with the upper and lower decks of a' grain binder, and check springs depending from the lower edge of the upper deck to the lower deck of a supporting frame carried by and disposed and held in parallelism to the upper deck, and

a yieldable grain strai htening arm supported on the upper end of said frame and ex: tending downwardly from the upper edge portion of the upper deck toward the upper surface of the lower deck and disposed in contact therewith rearwardly of the check springs, thereby acting to straighten the grain during its passage to the check springs.

2. The combination with the upper and lower decks of a grain binder, and check springs depending from the lower edge of the upper deck to the lower deck of a supporting frame carried by and disposed and held in parallelism to the upper deck, and

an oscillatory element pivotally supported on the upper end of said frame and provided with a grain retaining arm extending downwardly from the upper edge portion of the upper deck toward the upper surface of the lower deck and disposed in contact therewith rearwardly of the check springs, thereby acting to straighten the grain during its passage to the check springs, and yieldable means operatively connected to said element and acting to yieldably retain said arm in the path of the grain.

3. The combination with the canvas and upper and lower decks of a grain binder,

of a supporting frame carried by and disposed and held in'parallelism to the upper deck, and an oscillatory element pivotally supported on the upper end. of said frame and provided with a grain retaining arm extending downwardly from the upper edge portion of the upper deck toward the upper surface of the lower deck and disposed in contact therewith, thereby acting to straight en the grain-during its passage from the canvas, said element having an extension arm, and yieldable tensioning means connecting the extension arm and a portion of the support frame or structure to sotension the element as to hold the retaining arm yieldably in the path of the grain as it leaves the canvas.

4. The combination with the upper and lower decks of a grain binder, which includes a bundle packing mechanism, and wherein the upper deck includes a lower rail of a frame connected to the lower rail of the upper deck, said frame having angular extensions ongaging under the upper edge of the upper deck, thereby fastening the frame detachably to the upper deck, an oscillatory element fulcrumed upon the upper endof said frame and provided with aretainingarm extending downwardly and resting upon the surface of the lower deck, and tensloning means connecting said oscillatory element with the frame to hold the arm yieldably in engagement with the lower deck.

5. The combination with the upper and lower decks of a grain binder, which includes a bundle packing mechanism, and

wherein the upper deck includes a lower rail of a frame connected to the lower rail of the upper deck, said frame having angular extensions engaging under the upper edge of the upper deck, thereby fastening the frame detachably to the upper deck, an oscillatory element fulcrumed upon the upper end of said frame and provided with a retaining arm extending downwardly and resting upon the surface of the lower deck, said 0scillatory element including a short extension arm, and a coil spring connected to the short extension arm and in turn to the frame, thereby so tensioning the element, as to hold the retaining arm yieldably in the path of the grain as it leaves the canvas.

6. The combination with the lower deck of a grain binder, and check springs depending toward said lower deck, of a vertically yieldable grain straightening arm depending toward the lower deck and disposed rearwardly of the check springs for straightening the grain during its passage to said check springs.

In testimony whereof I hereunto aflix my signature.
