GRAIN BINDER.

Application filed .Tune 16, 1925 Seria lNo. 37,487.

This invention relates broadly to an i1nprovedgraln binder, but has more particular reference to a means which is associated with a conventional binder for lifting down trodden grain to properly position it to be er on a lane to dis 3038 it verv close to the ground, so that the blades may engage and lift the grain up in the path of operation of the cutting means.

The invention is characterized by a structure, which is such as to permit it to be mounted upon a. more or less conventional binder, withoutrequiring extensive alterations and utilizing at its source of power a driven mechanism of the binder.

Another feature is the structure en'iploved tor n'iount-ing the grain hoisting reel in a manner to permit it to be lifted on an angle with respect to the surface of the ground, or to be bodily lifted in a horizontal plane, during the movement of the binder over the field.

A further feature is the means employed for hoisting the reel, and a friction drive structure in which the speed of rotation of the reel. may be regulated at will.

'Othcr features and advantages of the invcntion will become apparent from the il ol lowing description and drmvings.

in the accompanying drawing, 'hn'ming a part oi this application. and in which like muncrals are employed to designatedike parts throughoutthe same: i

Figure 1 is a top plan view of a portion of a conventional binder equipped with a device. constructed in accordance with the present invention.

Figure 2 is a front elevation of the same.

Figure 3 is a detail view on an enlarged scale. showing certain of the structure more plainly.

l igiue d is a detail sectional and elevz tional ligure showing the means employed for mounting the reel.

Figure 5 is a view showing the approximate relation to the cutter bar or sickle bar.

Referring to Figure 1 of the drawing, it will be seen that the reference characters 1. 2, and 3 designate parts of a conventional binder. The part 3 is an endless sprocket chain which is constructed to opvidcd,

era-to a bevelled gear 4, meshing with a' relatively small bevelled pinion 5. The pinion is keyed upon a rotatably mounted shaft 6, provided on its opposite end with a friction driving disc 7. Appropriate bearing brackets are provided for mounting the shaft. is a driven disc 8 carried by a polygonal sleeve 9, into avhich correspondingly shaped rod 10 telescopes. This rod 10 carries a bevelled gear 11. It should be noted that there is a collar fixedly mounted on the sleeve 9 and that a pivotally mounted shitting lever 12 serves to act upon this collar to in turn move the sleeve and friction disc 8 toward and from the periphery of the driving disc 7 Obviously, this changes the speed of rotation. 1

Disposed across the front of theplattorm 1 is the usual reciprocatory sickle or cutter bar 13, in advance of which is the grain litting reel, Noting Figure 3, it will be seen that this reel comprises a plurality of blades 14' carried by endless chains 15 trained over sprocket wheels 16. The sprocket wheels 16 adjacent the cutter bar are mounted upon an operating shaft 17, which is provided at its outer end with a gearing in mesh with the aforesaid gear 11. The reel, as a whole, may be designated by the reference character 19, and it will be noted that this reel is combined between and mounted on a pair of upwardly swing-able arms 20, pivoted at 21 upon the hollow standards 22 (sec l igurc l). W'hilo observing this figure, it will be noticed that this standard is proat its bottom, with nut 23 which is threaded upon a screw threaded vertical shaft 524. The shaft, in turn, is pro vided at its bottom witha head 25, swivelly mounted in a hollow base bar i6.- On its upper end the shaiit is provided with a bevelled gear 27. It is of course understood that this structure is duplicated at both ends of the reel, and it is clear that by rotating the swivelled screw sh'ait, the hollow standards 22 will be lifted upwardly and will, in turn, lift. the entire reel bodily, upwardly in a horizontal plane. In order to rotate the screw shaft, a connecting shaft 28 (see Figure 2) is employed. this being provided at its opposite ends with bevelled gears 29 in mesh with the gears 27. sriaped bearing brackets 30 are provided, for journaling of the shaft 28. Extending diag- In variable contact with the disc 7 Suitable U- onally from one end of the shaft 28 is an operating rod 31, having a gear at one end, in mesh with the adjacent bevelled gear 27, and having a hand wheel 32 on its opposite end.

As before intimated, independent means is provided for lifting the reel upwardly on an angle with respect to the surface of the ground. In carrying out this end, we pro vide the aforesaid arms 20 at their outer ends with upstanding extensions 33, and connect a pair of downwardly diverging cables 34-, thereto. A main hoisting cable Sails connected with the cables 3-l-, passes upimrdly over a pulley 36 extending from the shaft E28 and then is wrapped about adrum 37 wound or unwound by the hand wheel 3. In operation, power is derived from the intermeshing bevelled gear and pinion i and 5 receiving its energy from the sprocket chain 'lhrough the medium of the various shafts, gearing and friction drive, the shaft 17 is set into rotation for ope ating the endless chains of the reel. The chains in turn carry the blades around in a customary manner, and the blades being close to the ground move against and beneath the downturned grain as represented in Figure 3, lifting the grain up to a'natural posi- .tion so that it may be easily cut by the usual cutting means. The relation of the reel to the cutting means is clearly shown in Figure :3. If it is desired to lift the entire reel up to clear the ground or elevations, this is done by rotating the screw shaft 2%, as before stated. If it is desired to simply lift up the outer end of the reel, this is done through the medium of the flexible cables, pulley, drum, etc. Undoubtedly, a consideration of the description, in connection with the drawings, will enable persons skilled in the art, to which the invention relates to obtain a clear understanding of the same. Therefore, a more lengthy description is thought unnecessary.

lVhile the preferred embodiment of the invention has beenshown, it is to be understood that various changes in the size, shape, and arrangement of parts may be resorted to, Without departing from the spirit of the invention or the scope of the appended claim.

Having thus described the invention, what is claimed is:

In a grain binder, a pair of screw threaded shafts, hollow base members supported on the binder :t'orwardly of the cutter bar of said binder, heads formed on the lower ends of the shafts and swivelly mounted in the respective hollow base members, said screw threaded shafts being ar 'anged in vertical spaced relation, hollow standards threaded onthe respective shafts and adapted for vertical adjustment thereon, a pair of laterally extending arms pivot-ally sccured at their inner ends to the lower portions of the respective standards, transverse shafts journaled for rotation between the inner and outer ends of the laterally extend ing arms, aligning sprocket wheels arranged on said transverse shafts, transverse shafts journalcd between theinner and outer ends of the laterally extending arn1s,-aligning sprocket wheels arranged on said shafts, blades extending transversely across the sprocket chains trained over the aligning sprocket wheels, blades extending transversely across the sprocket chains and secured thereto at spaced intervals, at horizontal rotatableshaft supported adjacent the upper ends of the verti-al shafts, intermeshing gears arranged on the upper ends of the vertical shafts and the respective ends of the adjacent horizontal shaft whereby the hollow standards may be vertically adjusted on the vertical shaft when the horizontal shaftis actuated, upwardly directed extensions formed on the outer ends of the laterally disposed arms, cables attached at their outer ends to the outer ends of the respective upwardly directed extensions. and an additional cable attached to the inner ends of said aforementioned ables for actuating the same whereby to raise the free ends of the laterally disposed arms upwardly.

In testimony whereof We allix our signatures.
