The frame F 01 the improved machine is sup -vorted upon a bull-wheel 1 anda grails wheel 2, from the former of which power is derived io drive ihe moving parts of the machine. The said wheels are disposed wii-liiheir 5 axes in alinement with each Oi-llflf. or in the same transverse perpendicular plane in oras will be seen at 19 19", and the conical portions 17 17 are provided with-spirally-disfi posed feed-flanges 20 20, whereby the conical portions are converted into feed-angers,

which assist in gathering the cornstalks and1 5 in guiding the same between the longitudi'-' nall'v-corrugated portions of the rolls, said.

feed-flanges being spaced apart at the forward extremities or apices of the conical mcmbers,'forming wide openings or passages 00 for the admission of the stalks, upon which the spiral flanges by the rotation of the rolls gradually close, so as'to feed the stalks posi-' lively between the corrugated portions of the rolls. Bearing-blocks 21 21 are supported [05 ings for the lower gym extremities ofthe rolls. The reduced portions or shanks 18 18 together, so as to rotate simultaneously in the direction of each "other;

The rolls, as wilhbeclearlf seen by reference to F1 l of the ldrawin 's, are supported at a suite is inclination t e front-ends of said rolls being-supported'atsucha distance above theground; that-not only the standing stalks, but; also. suchstalks' as have been beaten down or toplpled over, will he certainly engaged by t e gatherers and will be thereby guided between the conical au er-v shaxped members of the rolls, whereby t is wil be further guided in'a rearward direction u ri'ti,l the stalks are laid hold'of by the longitudinally-corrugated c lindric'allportions of the rolls, as will herea ilyunderstood.

To assist' in" gathering and guiding the icorn'stalks; there areprovided a pair of reels,

The sh tg32 carries a s rocket-wheel 33,- which is. connected a l .bjelt 34 with a sprocket-wheel '35 th! 3;i'Qll'JRf-Which is thereby driven in-th'e pro ei direction, transmitting motion, as herein eforedescribed; to its mate. "Sup ortedin suitable bearings-at right angles to t e axes of the rolls and to that of the shaft 27 are a pair of shafts 36 and 36, the former of which is extended-downwardly and carries a bevel-pinion 37, meshing with a bevel-pinion 38 upon the driven shaft 27,

from which motion is thus transmitted to the shaft 36. A counter-shaft 39 is provided having a bevel-pinion 40, meshing with a bevel-pinion 41 upon the shaft 36. Said counter-shaft has also a bevel-pinion 42, meshing with a bevel-pinion 43 upon the shaft 36, which latter will thereby be driven reverselly to the shaft 36, thegearing being suitably arranged with this end in view. of said rolls are journaled in suit-able bear- 5 ings 221and 22 upon the frame. Said shanks i or reduced portions are also provided in rear P of said bearings with intermeshin pinions 23 and 23, whereby saidrol'ls will e geared -whiohis parallel to the plane of the axes of the rolls, the inner or proximate flights of said chains being disposed as close as conven ient to the faces of the rolls onthe downgoing sides of the latter. The links of the conveyer'chains are provided at intervals with lugs or fingers 47 47, adapted to engagefirst the stalks and afterward the detached ears of. GOI'IlpSflid fingers serving to convey the ears over the smooth cylindrical portions of the rolls, whereby the husks are stripped from the ears.

ing with a bevel-pinion upon a shaft 57,

which latter is provided at its opposite end with a bevelp.inion58, meshing with a bevelgear 59 upon. the driven shaft 27, as-will be best seen in Fig. 2 of the drawings. The husked ears are guided to the elevator, over an inclined chute 60, into the upper ends of 'whichthe ears are discharged over the rear .or upper ends of the ylindrical portions of the-rolls between the shanks or reduced por-' tions 18 18' of said rolls.

From-the foregoing description, taken in connection with the drawings hereto an-.

' hold of the cornstalks that are to be operated upon and also in order to enable the I said stalks to pass between the. rolls, the

diameters of which are partly reduced by forming the grooves or corrugations therein, The rolls will be rotated at such speed that the longest stalks will..be.buckled down between the corrugated portions of the rolls, and the ears will be snapped from the stalks by the snapping-plates, which are disposed above .said grooved or corrugated portions. The conveyor-chains will operate to move the stalks rearwardly between the rolls as the machine advances, and when the ears are snapped from the stalks they will be engaged by the fingers of the conveyer-chains and will thereby be pushed'ofi the snapping.- plates and onto the smooth cylindrical portions of the rolls and upwardly and rear-.

wardly over the faces of the rolls. The

', smooth cylindrical portion of the rolls will lay hold of the husks, which latter will there-- by be torn or stripped from the ears, the husked ears being conveyed or pushed by the fingers of the conveyer-chains in an upward and rearward direction until they are discharged upon the chute 60, whereby'they are guided to the elevator, which serves to carry them to the place of deposit.

This improved machine, as will beseen from'the foregoing description, is extremely simple in construction, the snapping and husking operatams being performed by a singlepair of rolls which are driven without the intervention of complicated mechanism of any kind. It is obvious that the mechan ism maybe duplicated when desired, so as to enable the machine to operate upon a plurality of rows instead of upon 'a single row of corn.
