'SPEGIFIGATION forming part of Letters Patent No. 436,386, dated September 16, 1890.

Apnlication filed March 10, 1890- Serial No. 343,244. (No model.)

To allwhom it may concern:

Be it known that'l, Aueusr STEINER, a citizen of the United States, residing at Homewood,in the county of Cook and State of Illinois, have invented a new and useful Improvement in Corn-Huskers, of which the following is a specification.

The main object of this invention is to provide a machine which is capable of traversing the fields of corn and stripping the cars from the stalks, and then husking or shucking the same in a thorough manner; but, if desired,

. the machine may be used as a stationary one and the husking elfectively produced.

The invention consists in the construction and combinations hereinafter described, and then. more particularly pointedout in the claims.

Like letters refer to the same parts in the several figures of the drawings, in which-'- Figure 1 is a plan View of my machine, ar-

ranged with two pairs of husking-rolls at right angles to each other. Fig. 2 is a longitudinal vertical section of the same. Fig; 3 1s a vertical cross-section of my mach-me with the conveyor arranged so as to be immediately over the line between the pairs of rolls and showing the ears of corn. immediately under Such conveyer. Fig. 4 is a View in detail of two pairs of husking-rolls arrangedin operative relation. Fig. 5 is a detailview showing the relation of the conveyor and divider to the rolls. Fig. 6 is a front end view of .the

conical guiders in position for operation, and

of a portion of the driving mechanism. Figs. 7- and 8 are detail views showing the manner of hing-ing the front portions of the conical guiders, and Fig. 9 is a detail perspective of the'bow-spring and its connection tothe two frames.

A is the main frame of the machine, and it is of such suitable material and construction as to best adapt it for thepurpose intended.

Suitably journaled in the mainframe is themain or power shaft B. This power-shaft derives its motion from a pair of traction-wheels,

as shown in the drawings, or. in case the machine is stationary, from any suitable motorhand, steam, electric, &c.

:while upon the'stalk, and one officc of the Ordinarily'the ears'of corn are shucked ping-rolls, are mounted in the frame, as will, hereinafter be described, and serve to detach or sever the car from such stalk. In. advance of the snapping-rolls are arranged suitable devices for feeding and guiding the stalks and the ears to the snapping-rolls. These de-' vices, which I term guiders, may be of various constructions; but I prefer to employ two conical and hollow pieces I) D, which inclose chains or belts provided with spikes, which latter move along and extend through longitudinal slots cut in the inner sides of the conical guiders. The spiked belts are lettered E.E',..and are mounted upon sprockets suitably geared to and driven froin the main or power shaft. ers and between the spiked belt-s gradually I narrows as the snapping-rolls are approached,

may be strongly'held and adso that the corn vanced as it is being delivered to such rolls. Just at this point of delivery it is well to place curved guards or shields a a, behind which the spikes may turn, and thus prevent The space between the guid-,

the corn from following the spikes on the 1 belts. The forward portions of the conical guiders may be hinged to the rear portions,"

as clearly shown in Figs. 7 and8of the draw- 1 ings, so that such forward portions may be depressed to catch such stalks of corn as may not be standing upright. If the guiders were angular in cross-section there would be danger of the stalks breaking while being drawn over such angles, and of the ears of corn falling upon the groundloefore being caught by the snapping and husking mechanism, and to avoid this danger I prefer to curve the ex posed portion of such guiders.

The snapping-rolls O O are set a slightdistauce apart, with their rear ends journaled in a cross-bar of the main frame,but with their front ends 3' ournaled, respectively, in the main frame, and in asupplemental frame F, which latter will hereinafter be more particularly described. These rollsare formed withlongspiral corrugations, so made that the corrugations of one roll mesh with those of the companion too roll, and that the rolls have, respectively, right and left corrugations.- -;Su ch rolls are also they will not cut the stalks,

' yet the fact supported bythe sprin'gwillenablesuch ends action,

The corrugations ot the rolls are rounded, so that the operation of the machine would be impededby pieces of stalk, 850., but my round corrugations merely forcibly snap the cars from the stems, allowing the' stalks to pass through without breaking. It the corrugations fail to snap the cars from the stems of the stalk they will at least feed them forward rapidly, and the spiral'ribs will bya shearing action certainly etfect I long spiralof the ribs will cause asuccessive so commonly resulting from the action of straight ribs. H

A bow-spring G,Ipreferably made of steel,

The spring likewise-permits the supplemental'frame and the other parts mounted therein to give or placed under an uncommonstrain, and'at the same time the spring affords a convenient detachable support, whereby any ofif the parts secured to or mounted in the mental frame may be detached, and replaced.

Such an arrangement is preferable when the shucks are unusually hard to remove from the corn, and in locations where the crop of corn is very heavy it has been found advantageous to duplicate the pairs of rolls in lateral arrangement, as is shown most clearly in Figs. 4 and 5 of the It has been found, however, that generally but one pair of husk ing-rolls need be employed, and in such event I prefer to arrange them at the rear of the machine and to have the-ears of corn which fall from the snapping-rolls; drop upon a platform and be fed by a suit-able conveyor to the husk 'ingrolls. One huskingrollof each pair should havea raised ribwith a serratedinuer edge wound spirally around it, while the other roll 0t the pair may have spirally-arranged rows project from its surface. A chain belt I, provided with dles, is arranged 1 serves toconveythe corn along and at the same time hold the ears down to the gripping The husk towardeach andhusking action of such rolls.
