ried by the frame out of alignment and to This invention relates to corn pickers, it

also bring the outer gathering unit closer to more particularly relating to the construction of the supporting frame and the means for tilting the frame. V V One of the objects of my invention is'to provide a supporting frame for a corn picker machine which will be extremely light'but at the same time rigid enough to prevent sagging in the middle and resist tortional -stresses due to the weight of the various mechanisms mounted upon it; a further and more specific object'being to provide means whereby such frame after the assembly of the various parts thereon, including the gathll jllllg and snapping devices, may be realigned if necessary to properly position said devices with relation to the ground line.

A further object of the invention is to pro -vide for efiectively supporting and tilting the '.)frame to adjust the position of the gathering devices with relation to the ground.

In the accompanying drawings Fig. 1 is a top plan view of the frame con .struction and tilting device. 1 515' Fig. 2 is a top plan view of a portion of the same showing a modification. j a

The particular type of corn picking machine embodying my improvements is one which is tractor drawn and in which the hitch devices are applied at one side of the machine and the gathering and picking mechanisms are supported on the-opposite side of the machine. The natural tendency of the weight of these mechanisms is to drag that side of the frame downwardly thereon causing a torsion or twist inth efra mewhich 53 has the effect of throwing the mechanism cargathering units-are employed as in the presincorporated in theframe construction bracing means for resisting or counteracting the tendency of the weight of the gathering and picking mechanism of a nature whereby distortion of the frame structure is prevented, or when distorted may be restored to and maintained in correct alignment.

The frame which I employ is of open boxlike characterconstructed preferably of angle iron. The characters 1 and 2 represent front by longitudinally extending bars 3. The characters 4 and 5 represent front and rear lower cross rails connected by longitudinal cross rails 6 at the respective ends thereof. A series of vertical bars 7 connect the cross rails, and 8, 8 are a series of horizontal diagonal bars connecting the lower rails 4 and 5. r The upper and lower front rails 1 and 4 are connected by diagonal bars 9, and the rear upper and lower frame bars 2 and 5 are connected by diagonal bars 10. The frame is supported on wheels 11 journaled on stub horizontal alignment with the front rails thereof so that the frame in tilting swings about the axes of the wheels. In the present case two gathering and picking mechanisms are employed which are carriedby that side of the frame opposite to the one to which the draft devices are secured. To support these mechanisms, the main frame is provided with two pairs of forwardly and downwardly'extending members 18 having flared ends 13 secured at their upper ends to the main cross rail 1, and further braced and secured to the lowercross rails 4' and 5 by means of forwardly extending bars 14, across .the outer ends of which is secured a bar 15 which in turn is secured to the inner members of the pairs of members 13 by means of angle irons 16.

outermost'members of the pairs of members 13 are pi-votally secured to the lower cross the ground'than the inner one where two entcase. To overcome this difliculty'I have and rear uppercross rails connected together axles 12 which are secured to the frame in Two members 17 rigidly secured to the' throughout which a rail 4 and extend through underneath to the rear lower cross rail 5 to which they are adjustably attached, there being bolts 18 connecting the members 17 respectively with the members 6 and 8 by means of which the members 17 may be swung on their pivotal connection with the members 4 and the ends 13' of the outer members 13 thereby shifted to vary the width of the throats of the gathering frames; the members 13'having sufiicient natural resiliency to permit of this.

The hitch or draft devices consist of a forwardly extending beam 26, a diagonally-extending beam 27, and diagonal cross bars 28 connecting and bracing the two beams. Each beam. 26 and 27 is further braced by an upwardly bent member 29 and 30 respectively, each. of which is rigidly secured at'each end to their respective beams and connected by iiv'ertical struts 31 while a transverse connector member 32 is joined to both beams 29 and 30 at their high points. At the forward ends of the beams 26 and 27 is a plate 33 to which a clevis 34 is secured having an opening 35 pin (not shown) is inserted.

The hitch deviceis pivotally connected to the forward part of the frame, the beam 26 being hinged to the stub axle 12 at the right hand side, while the beam 27 is hinged to the main'lower cross rail, through the medium ofe, U-shaped bracket 36 secured to said cross rai I A'tilti'ng arm consisting of a pair of bars -.=37 d 38 braced by struts 39 and to which is rigidly secured to the main frame, the upper bar 37 being rigidly secured to a bracket 37 bolted to the upper cross rail 1 (Fig. 8), while the lower bar is rigidly attached to the bar 17 (Fig. 9). A toothed segment 41 which cooperates with a latch 42 slidably mounted on the handle 40 is attached to both bars 27 and 30 and has an upper notch 43 and a series ofother notches-44, 44, the upper notch 43 serving to maintain the frame in position for transportation, while the series of notches 1 44 allow for various heights of the imple- "by a spring 46 toothed segment 41 and mentwhen inoperation in the field. The latch 42 has a tooth adapted'to fit into anyof the notches and is maintained therein a link 47 connects the latch wlth a grip 48. i

' Since theforward part of the hitch is cou pled to a fixed tractor drawn bar, and as the tilting arm is rigidly locked to the the frame pivots on the wheels 11, it follows that the forward portions of the gathering units can be held av fixed distance from the ground, and that the outergathering unit can be held as far from the ground as the inner gathering unit,

essential that an open box-like frame must 1 contain horizontal and vertical spacers, to-

gether with cooperating horizontal and vertical bracing means. In order to correct any torsion in an open box-like frame spaced and braced as here mentioned, one of the braces in'the frame is made adjustable as to length. The preferable construction is to make the one horizontal and diagonal brace composed of rods 19 and 20 with turn buckle 21 whereby the brace may be adjusted as to length, as the adjustable brace, as it is the most directly located with reference to the outer gathering unit.

By-this construction an extremely light and very strong frame is provided of a nature which will permit the frame parts to be originally so assembled and aligned as toproperly adjust the gathering and picking mechanisms with relation to the ground line and also of such a nature as to provide for subsequently aligning the parts of the main frame in the event that that side of the frame which carries the two gathering and picking mechanisms should sag under the weights of the mechanisms and thereby distort the frame and cause a disalignment of the mechanism, it only being necessary to adjust the two-part brace member in order to effectively restore the parts of the frame to their original position. It will be understood that this frame carries not only the gathering and picking mechanisms, but also huskingrolls and conveying devices and that it is important for the effective operation of such parts that the frame should be kept properly aligned; also, it is important where a plurality of gathering mechanisms are employed, that these mechanisms should be in uniform relation with the ground. A

The diagonally arranged member of the draft device is the one which performs the major part of the operation of drawing the implement, the other longitudinally arranged draft member being more to stabilize and cause the implement to run in a true course. The points of the gathering units may be adjusted at any time with relation to the ground to enable them to pick up down corn stalks. and'may be raised high above the ground when desired, for transportation purposes;

In Fig. 2 there isshowna modification in' which a compression member is employed consisting of two parts 23 and 24 connected by a turn-buckle 25 which is threaded upon both of the brace members.

In this case thel member 23 is connected to the-outer end'ofthe rearrail 2 and the member 24 to an intermediate portion ofthe frontrail 1. To raise the 1 forward partof the frame, the brace member is lengthened by turning the buckle 25, it being understood that the brace members are oppositely threaded.
