HARVESTER BINDER Filed Dec. 10, 1928 .nvanfwr Nicholas RNels on Mwxz, 21g-WW@ Managua Patented Apr. 15, 1930 p UNITED STATE PATENT @FFlCE NICHOLAS NELSON, OF EAST MOLINE, ILLINOIS, ASSIGNOR TO DEERE & COMPANY, OF MOLINE, ILLINOIS, A CORPORATION F ILLINOIS HARVESTER BINDER Application filed December 10, 1928. Serial No. 324,972.

My invention relates to harvester binders and has particular reference to devices einployed to operate upon the stalks of the cut grain as the latter is delivered to the binder e? deck and passes to the sheaf forming and binding mechanism.

My invention has for its object to provide a headboard having means of adjustment by which it can be moved to accommodate cut io grain of varying lengths or can be moved out of operation if the cut grain is of greater length than usual and upon which a headboard would be inoperative.

The object of a headboard is to facilitate formation of the cut grain intosheaves by cooperation with the buttboard of the harvester, to so aline the butts of the stalks with each other that a bound sheaf will present a flat butt and consequently the formation of 29 sheaves into shocks can be more readily and effectively accomplished.

Referring to the drawings in which similar numerals indicate identical parts- Figure 1 illustrates the application of my device, suiicient of a harvester binder being shown for that purpose.

Figure 2 is an enlarged front view of the means employed to support the headboard on the harvester.

lligure 3 is a section on the line 3-3 of Figure 2, and

Figure 4 illustrates the means securing the headboard to a part of the supporting mechanism.

The parts of a harvester binder shown are well known and include the deck 1, an extension 2 thereof, and the hood or deck cover 3, the latter attached to the upper part of the elevator frame Il, and forming with the deck i0 i a passage through which the cut grain moves to the binding mechanism. A huttboard is shown at 5, mounted as usual, to operate over the forward end ef the binder deck. A casting 6 is secured to the rear part 4 of the elevater frame and has a flange 7 to which is boltedV a member 8. Forming part of the member 8 is a bearing 9, and integral therewith is a. forwardly extending plate 10.

A cylindrical part 11, of a cast-ing 12 is rotatably journaled in the bearing 9 and from it, and integral therewith, extends an arcuate plate 13 in which is a slot 14 concentric with the axis of the part 11; the plate 13 contacts with the plate and is held in contact by a bolt 15 which extends through the plate 10 and the slot 11i, in the plate 11, and by operation of a nut 16, on the bolt 15, the plates 10 and 13 are held rigidly in Contact or loosened for purpose of adjustment. On the opposite side of the plate 13 the casting 12 is extended as a rectangular sleeve 17.

Entending from end to end of the casting 12 is a rectangular hole, shown in dotted lines on igure 2, in which is slidably mounted a bar 18 bent stubbleward, intermediate its length, to provide an arm 19 on which is supported a headboard 20. The manner of curing the headboard 2O to the arm 19 is well known in the art and comprises straps 21 and 22 having alined bearings 23 and 24; in which a rounded and downwardly bent portion of the arm 19 is journaled. On the downwardly bent portion of the arm 19, and above the bearing 24, is a coiled spring 25, one end portion of which is straightened and bears against the headboard 20, the other end of the spring being also straightened and engaging with any one of a series of notches in the castellated end of a sleeve 26 mounted on the downwardly bent portion of the arm 19 and secured thereon by a pin or bolt. Integral with the sleeve 26 is a stop 27 against which the headboard contacts to limit its forward swing. This construction, as stated, is old in the art, but it is described to show that the headboard is resiliently held on its support so that it will yield to increase in bulk of the incoming grain and at the same time have Asufficient pressure on the grain to assist the buttboard in making a flat butted shea'.

To accommodate the headboard to the length of grain in a harvest, the set screw 28, in the casting 12 and contacting with the bar 18, is loosened and the bar 18 moved to adjust the headboard toward or from the buttboard 5, and when the desired adjustment has been made, the set screw 28 is operated to hold the bar 18 and the headboard 20 in position.

When the grain is of an abnormal length,

and the heads project beyond the decl; 1, or for any other reason, it may be necessary to remove the headboard from the path of the incoming grain, this removal can be readily accomplished by loosening the set screw 2S and withdrawing the bar 18 from the casting 12. As previously explained, the bar 1S, on the arm 19 of which the headboard is mounted, is rectangular in cross-section and held in a similarly formed hole or opening in the casting 12, the latter rotatably mounted in the bearing 9 and secured from movement by a bolt 15, which operates to hold rigidly together the plate 10, integral with the bearing 9, and the plate 13, integral with the casting 12; now it follows that if it is desirable to remove the headboard 20 from operation, without dismounting it from the harvester, it can-be accomplished by loosening the nut 16, on the bolt 15, then manually raising the headboard Q0 and the bar 18, the casting 1Q rotating freely in the bearing 9, and the plate 13, because of the slot 1l, moving simultaneously to a new adjustment, after which the nut 16 is tightened, the parts are again held rigidly together and the headboard is held in a raised position.

What I claim is- 1. In a harvester-binder, the combination with the frame thereof and the binder-decl; of a headboard adjustably supported on the upper rear of the elevator frame above the binder-deck, and means on the frame operative to adjust the headboard bodily forwardly or rearwardl 2. In a harvester-binder, the combination with the frame thereof and the binder-deck, of a headboard adjustably supported on the frame above the binder-deck, and means mounted on the frame operative to adjust the headboard vertically.

3. In a harvester-binder, the combination with the frame thereof and the binder-deck, of a headboard adjustably supported on the frame above the binder-deck` means mounted on the frame operative to adjust the headboard bodily forwardly or rearwardly, and means on the frame operative to raise or lower the headboard.

4. In a harvester-binder, the combination with the frame thereof and the binder-deck, of a casting mounted on the frame, a supporting member including a bearing secured on the casting, a rotatable casting journaled in the bearing, a bar supported in the rotatable casting and longitudinally movable therein, said bar bent intermediate its length to provide an arm extending stubbleward, and a headboard mounted on the stubbleward and part of said arm.

.- the casting, a rotatable casting journaled in the bearing, a bar supported in the rotatable casting and longitudinally movable therein, said bar bent intermediate its length to provide an arm extending stubbleward, a downward extension at the end of said arm, and a headboard mounted on said extension.

6. In a harvester-binder, the combination with the frame thereof and the binder-deck, of a casting mounted on the frame, a supporting member including a bearing secured on the casting, a plate integral with said member and extending therefrom in a grainward direction, a rotatable casting journaled in the bearing and having a plate extending therefrom in parallelism with the plate on said member and in contact therewith, a slot in the plate on the rotatable casting and concentric with the axis thereof, an opening in said rotatable casting extending the length thereof, a bar journaled in said opening and longitudinally adjustable therein, said bar bent intermediate its length to provide an arm extending stubbleward, a downward extension at the end of said arm, a headboard mounted on said extension, and a bolt extending through said slot and the plate on said member and a nut on said bolt operative to hold said plates together, or to release said plates from engagement with each other whereby said rotatable casting is actuable to raise or lower the headboard.
