fie e m qhenwg i L i e imien n r keeping the ears un or miy distributed overjhe between frame plates 35 and 36 havingtheir ends adjacent the receiving end of the husking unit journaled upon the shaft 28. Secured to the ends of the frame plates 35 and 36 adjacent the discharge end of the husking unit is an inverted U-shaped tie member comprising side members 38 and a top member 40. The side members 33 are provided with slots 41 to receive a clamping bolt $3 for an adjustable angle stop 44 adapted to rest upon the upper edge of the side member and 2| for supporting the lower end of the frame and for permitting the adjustment of the vertical distance between the feeding mechanism and the adjacent ends of the husking rolls.

Since the supporting frame for the spiral feed member is pivoted on the main shaft 28, the

blades. A single one of the tabs 10 may be attached to the blade near its forward end to assist in moving the corn away from the adjacent side of the husking bed.

To appreciate the advantages of my feed mechanism, it is here pointed out that the rubber rolls l8, I8, [8 are rotating to the right, or clockwise, While the iron rolls I1, 11, I! which, located below the upper surfaces of the rubber rolls, are rotatingto the left, or anti-clockwise. Since the rubber rolls afford the frictional contact with the com, the tendency will be for the corn in the husk unit to be moved transversely across the bed lower end of this frame is free to rise and fall within the limits of the stops 44, and the mechanism will accommodate itself to different size ears with but little attention.

The right-hand ends of the shafts 28, 29 and 30, looking toward the'delivery end of the'husking unit, are extended outwardly beyond the side member 2| of. the metal housing, the shaft 28, through the adjustable bearing bracket 3|, the shafts 29 and 30, through slots 50 and 5|, provided in the side member 2|, and opening through the upper edge thereof.

Secured to the outer end of shaft 28 is a cogwheel 52, chain driven from the main drive mechanism of the picker. Also mounted upon the shaft 28, between the cogwheel 52 and the side member 2|, is'a cogwheel 53, chain connected with the cogwheel '54, on shaft 29. A second cogwheel 55, on shaft 29, is chain connected with a cogwheel 56, on shaft 30. By this driving arrangement, the three shafts 28, 29 and 30 will be positively driven in a clockwise direction.

The bearings for the shafts 29 and 36 are adjustably secured to the frame plates and 36 by means of bolts 65 extending through slots in said frame members 35 and 36. The frame member 36 is also provided with slots for the shafts 29 and 3B. This construction provides for adjustment of the shafts 29 and 30 longitudinally of the frame plates 35 and 36 for tensioning of the drive chains.

The side member 2| is reinforced and braced adjacent the edges of the slotted portions 56 and 51 by U-shaped members 64 and 65 fastened to the outerface of the side member 2|.

It is especially important in the husking of corn which is to be used for seed that abrasions to the outside covering of the corn kernel be avoided.

Since such abrasions might be produced by sharp corners or edges of the spiral blades 25, 26 and 21 striking the kernels, the following provisions are made for avoiding such injury.

Secured to the periphery of the spiral blade 25 and covering the advance corner thereof, is a circular rod 68 which may be welded to the outer edge of the blade. Since the blade 25 is the first to engage the corn as it enters the husking bed, the work required of it is greater than that required by the other two blades 26 and 21, and. consequently, it must have a greater stiffness than the latter blades.

The work surface for each of the blades 26 and 21 may be provided by tabs or extensions 10, 10 of material having substantially the same degree of flexibility as four or five ply rubber belting. These tabs 10, E0 are secured to spiral blades 26 and 21 at closely spaced intervals and extend outwardly therefrom as extensions of the spiral toward the right-hand side. perience, it has been found that in those husk As a matter of exunits, when the corn is moved into engagement :with' the husking rolls, the corn is actually piled and the advancing facesofthese spiral blades will engage thecorn to produce a moving force toward the'left side of the husking beda'nd against the force of the rubber rolls tending to move the ears of corn toward the right side of the bed.

Thes'e opposing forces will tendto swing the ears into parallelism with 'the husking rolls and to im-' part to the cars a rotary motion which will insure a complete stripping of the husk from the ear.

As is readily apparent fromexamination of Fig- "ures 2'and 3, the direction of movement of the bottom portions of each of the spiral blades 25,

26 and 2'! is in the directionto produce a downward movement of the corn along the husking bed in addition to the lateral component of movement imparted to the corn in the manner described above. a w

The right-hand ends of the: spiral blades are terminated as closely aspossibleto -the right-hand side ofthe nuski iei bed, while the left-hand ends of the b1adeS may bdtrrfiinated ata distanbe from the'left hand side of the, bed approximately half the width of" the rubber roll adjacent that side. Thus, while the force of the spiral members i i e e t d. 1 ,12 1 t e. em. tr ns r e o h bl n in i a d towa d h e tnd side is greater than that exerted in the opposite direc tion by therubber rollasuch forceis not exerted beybndithe oenter line r the rubber oll. at the left-handside ofithje huskii g bed, and since the rotationpf this roll is away from the adjacent side ,of thebed, there canbeno piling up or chok s. t, t ro r q a ed. tth e s e o the be s rimeetsheife d ns rat d ha ne e-l I; ment emb y n the. fea res .02. m in e qe; notonly saves wear and tear on the parts, but it lts. n a. cle ner a ,mp e e c e u ing r i n w h less ju y. to. the. sur ce of. the:
