BARNEY GRONKE, OF CHICAGO, ILLINGIS, ASSIGNOR T0 INTERNATIONAL HARVESTE COMPANY OF NEW! JERSEY, A COR'BGRATION OF NEW? JERSEY.

CORN-HUSKER.

To all whom it may concern:

Be it known that l, BARNEY GnoNKE, a citizen of the United States, residing at Chicago, in the county of Cook and State of Illinois, have invented certain new and useful Improvements in Corn-Huskers, of which the following is a, full, clear, and exact specification.

My invention relates to corn huskers.

It has for its object to agitate in an improved manner the ears fed to the husking rolls of a husker. A. further object of my invention is to guide the ears fed to the bushing rolls in an improved manner. I attain these objects by providing improved means operatively connected to the operating mechanism of the husker and movable thereby in planes parallel to the axes of the bushing rolls to agitate the ears dropping thereon from the hopper; the agitators moving through improved ear guides or deflectors acting to deflect ears between the active surfaces of the husking rolls.

In order that my invention may be clearly and fully disclosed, I have shown in the accompanying drawings one embodiment 'which it may assume in practice, illustrating the same in connection with a combined husker and shredder. t is, of course, to be understood, however, that the construction shown herein is susceptible of modification and use in other relations.

Figure 1 is a side elevation of a machine equipped with my improvement.

Fig. 2 is a sectional view taken on line 22 of Fig. 1. I

Fig. 3 is an end elevation of the husking rolls shown in Fig. 1.

Fig. a is a detail view in elevation of one of the agitators.

The construction shown, when broadly considered, comprises a frame 1 having a plurality of husking rolls 2 journaled therein and rotated through suitable power connections from a suitable pulley 3 to husk the ears fed thereto from the snapping rolls 1; suitable agitators 5 of an improved construction also operatively connected to the power pulley being movable through improved ear guides or deflectors 6 to distribute the ears to the husking rolls in an improved manner hereinafter described.

The frame 1 may obviously be of any desired construction. In the form shown herein, it is of the type used in connection Specification of Letters latent.

with combined huskers and shredders and is of substantially rectangular construction. The husking rolls 2 are journaled therein in suitable bearings and are disposed parallel to each other and at an angle to the horizontal as in the usual construction, being operatively connected through gearings 7, 8, etc, to the power pulley 3. (Fig. 1.) As in the usual construction, one of the husking rolls of each set is resiliently mounted, being provided with a horizontally disposed spring 9 which tends to force the same over toward its coeperating roll. (Fig. Further, as in the usual. construction, the upper ends of the huslring rolls are brought substantially beneath the snapping rolls lcurried on the up per part of the frame 0ppositc the platform 10, likewise driven from the power pulley 3, so that the ears snapped from the stalks and fed in from the platform 10 may be guided to the husking rolls by a suitable apron 11. Further, a chain and sprocket connection 12, 18, operatively connected to the power pulley 3 and the bushing roll rotating shaft 14, is provided to drive the feed chains 15 feeding the stalks to the snapping rolls, while an additional chain and sprocket connection 16 is provided to operate the screen. (Not shown.)

In my improvement the agitators 5 are operatively connected through sprockets 17 with the feed chains 15 in such a manner that the movement of the feed chains, and therefore the power pulley 3, is transmitted to these agitators. As shown in Figs. 1 and 1. each agitator is substantially triangular shaped, being provided with a curved elongated edge 18, and is attached at one of its corners to a short stub shaft 19 journaled in the frame substantially beneath the apron 11 and the upper ends of the bushing rolls and at one side of the same. In a preferred form a laterally extending sleeve 20 is preferably formed integral with each of the agitators 5, which is adapter.. to fit over the inner end of each shaft 19 and be attached thereto by a pin 21. Further, elongated bearing brackets 22 are provided upon the parallel horizontally disposed frame members 23 which inclose the bodies of the shaft 19 and support the same in alinement. Upon the outer end of each shaft 19 a crank 2a is provided which is pivotally connected at 25 to a pitman or link 26 upon the outside of the husking chamber which extends upwardly and forwardly diagonally across the side of the machine and is pivotally con nected at its upper end to a crank 27 upon the outer end of a shaft 28 carrying the sprockets 17. It is to be noted that by this construction the movement of the feed chains 15 is utilized to drive the agitators, that each agitator is independently driven through its own power connection and that all power connections for the agitators are located outside of the husking chamber. It is further to be noted that as the sprockets 17 are rotated, the agitators are oscillated about their pivots from the lower dotted position shown in Fig. l to the upper dotted position shown therein, or, as shown in Fig. 2, from the lower full line position to the upper full line position; the agitators moving in parallel planes between adjacent pairs of husking rolls in such a manner that a constant agitation of the ears is produced, one of the agitators being always in the raised position while the other is in its lowermost position.

The ear guides or deflectors 6 are provided between the rolls of adjacent pairs, two of the same being shown in this construction. It is to be noted that the deflectors are substantially L-shaped and so disposed as to bring their peaks in a line above the space between the rolls and that their edges extend parallel to the surfaces of the rolls. Each of these deflectors is attached to the lower end bearing of one of the husking rolls by means of a vertical bracket or support 29 and is further slotted longitudinally at 30 near its upper end in such a manner as to enable the agitators 5 to move freely therethrough. Obviously the upper ends of the deflectors 6 may be attached to the frame in any suitable manner. In a preferred construction they are, however, attached to the bearings of the husking rolls in substantially the same man ner as the lower ends thereof, shown in Fig. 3.

The operation of the construction shown is as follows: When the stalks carrying the ears are fed in from the platform 10, they are carried by the feed chains 15 over to thesnapping rolls 1-. These snapping rolls are driven from the pulley 8 through the power connections 7, 8 in such a manner that as the stalks are fed to them the same are drawn into the machine and the ears are severed therefrom. As the ears drop from the snapping rolls they fall down upon the apron l1 and from there slide or tumble upon the husking rolls 2. Obviously, when the stalks are being fed rapidly to the snapping rolls, there will be a tendency for the ears toaccumulate or clog at a point beneath the same and at the upper end of the husking rolls. For instance, the ears are sometimes lodged or jammed between the sides of the frame above the rolls in such a manner that the rotating husking rolls cannot grip the same. In my improvement the agitators 5, driven as they are through their pitman connection from the feed chains 15, are alternately raised and lowered so that they will break up any jam which may exist and dislodge the ears, freeing them so that they may slide down the husking rolls and be acted upon by the latter. It is to be noted that due to the alternate action of the agitators, the ears are forced up on one side so as to dislodge them and then are permitted to fall downward, or are given an additional impulse by the other agitator as the first moves downward in such a manner as to effectually prevent any clogging action. Attention is further directed to the fact that due to. the shape of the agitators and the fact that no more than the peaks of the same are permitted to pass out of the slots in the deflectors or ear guides, no ears may be caught or broken thereby as they are brought backward and no cars may be so lodged between the same as they are brought up as to damage the corn. Obviously, when the ears have been dislodged by the agitators, they will by gravity move down the slanting husking rolls and be acted upon by the same in the well known manner; the deflectors 6 acting to guide the same between the active or working surfaces of the rolls and thus so position the same that prior to the time that the ears pass off the ends of the rolls they are thoroughly husked.

While I have in this application described one form which my invention may assume an oscillating agitator supported by said frame and vibratable up and down between certain of said husking rolls, and means for vibrating said agitator.
