To (tZZ 11/71/0771, it may concern: i

Be it known that I, ALBERT VAN Nnss, of Chicago, in the county of Cook and State of Illinois, have invented certain new and useful Improvements in Corn Husking and Shredding Machines, of which the following is a .full, clear, and exact description, reference being had to the accompanying drawings, forming a part of this specification, in which Figure 1 is a longitudinal vertical sectional view of a portion of a corn husking and shredding machine embodying the features of my invention,taken upon the linezz, Fig. 2. Fig. 2 is a transverse vertical sectional view taken upon the line mm, Fig. 1, viewed in the direction of the arrow there shown; and Fig. 3 is a similar view to that shown in Fig. l, but indicating the different relative positions of the parts.

Corresponding letters of reference in the different figures indicate like parts.

The object of my invention is to provide a mechanism for use in corn husking and shredding machines which will not only aid in feeding the cornstalks to the snapping-rolls, but will also serve to properly adjust and present the ears of corn to the husking-rolls, so as to insure uniformity of action and pre vent any ears from passing through the machine without being husked.

To these ends my invention consists in providing a peculiar shaking mechanism which will not only act upon the stalks in feeding them to the machine, but will also serve to adjust the ears and control the movement thereof for the purpose stated, all of which is hereinafter more particularly described, and definitely pointed out in the claims.

Referring to the drawings, or represents that portion of the frame of the machine which is intended to support the usual snapping and feeding rolls, while 19 indicates the table upon which the cornstalks are placed for the purpose of feeding them to the machine.

Mounted in suitable bearings in the frame are the usual snapping-rolls c c, which may be constructed in any well-known manner, said rolls being arranged in the usual way transversely of the machine. In front of the snapping-rolls and journaled in suitable bearings supported by cross-bars d 61, Figs. 1 and 3, are the husking-rolls e, which are arranged in pairs, according to awell-known construction, each pair of rolls throughout the series being connected by means of gears f, Fig. 1, the shaft of one of said rolls being connected by means of a beveled gear (indicated in dotted lines in said figure) with a similar beveled gear mounted upon the shaft g, which is in turn connected with a source of power by means of suitable gears, as indicated in dotted lines in Fig. 1. The husking-rolls e are indicated in the usual way. Between the snapping-rolls c and the upper ends of the husking-rolls is located my improved compound shaking mechanism, which is constructed and arranged as follows:

Mounted upon and supported by cross-bars h i at the respective ends is an inclined apron 7', which is preferably made from sheet metal and arranged to extend entirely across the machine, as shown in Fig. 2. suspended at its respective ends by means of links 70, the upper ends of which are loosely attached to the frame a. The cross-bar h is supported at its respective ends by means of arms Z, which are rigidly bolted, as shown, to said cross-bars, while the lower ends are in operative connection with and supported upon crank-arms m, formed upon a shaft '12, upon which is mounted a pulley 0, Fig. 1, driven by means of a belt 19, which is trained over a corresponding pulley upon the shaft g, as indicated in dotted lines in said figure. Hinged at q to the main apronj is a headboard r, to the upper edge of which I have bolted lugs s, which are loosely connected by means of horizontal links If to lugs to, rigidly bolted to a cross-bar 12, forming a part of the frame and serving as a support for the feeding-table b. It will thus be seen that as the crank-shaft n is rotated a peculiar shaking motion is imparted to the apronj, the upper end of which nearly describes a circle, while the lower end vibrates back and forth, supported by the links 7a. A still different movement is imparted to the headboard r, the lower edge of which conforms to the movementof the upper end of the apron j, while the movement of the upper edge of the headboard is limited by that of the links If. The peculiar vibratory movements of the two parts are indi- The bar 2' is cated by the full and dotted lines in Fig. 3. Hinged-at w to the lower end of the apron j is a supplemental or extension apron z also made from sheet metal, the lower edge of which is provided with shoes y, Fig. 3, adapted to slide upon the upper surface of bars 6, which are arranged above and in vertical planes betweenthe respective pairsof rollers e, as clearly shown in Fig. 2. The apron ,7' and the supplemental apron y are corrugated, so as to form a series of depressions or troughs, the lowest lines of depression of which are in planes lying between the meeting faces of the rolls e, respectively, while the highest portions between the troughs are shown atj, Fig. 2, which are in alinement, respectively, with the dividing-bars e. The barse arebeveled laterally, asshown in said last-named figure, preferably to conform to the pitch of, the troughs int-he apronsj y. This construction of the troughed aprons and the beveled bars e, ar-rangedas shown, causes the ears-of corn when separated from the stalks toassume positions parallel to the husking-rolls, so that the husks may be readily grasped thereby. The vibratory movement of the aprons helps toinsure this result, andin order that said movement may prove more effectual, so asto prevent any tendency of the ears to;clog, I provide teeth j 7' in the bottoms and upon theridges between, which tend totforcethe ears along with each downward movement of the aprons.

The result of the improved construction and operation of my machine is that all'clogging both-of the ears and stalksis prevented and a, regular uniform movement of the ears isi-nsured, the axes of the ears being parallel: with that of the rolls, so that no ears are permitted to slide past the rolls unhusked.

Aside from the advantages'statedthe vibratoryyor four-motion movement of the apron serves to prevent the clogging of the stalks asthey are fedto the snapping-rolls and insures a regular and uniform feed;

Having thus described myinvention, what I claim, and desire to secure by Letters Patent, is'

1. The combinationwith the feed and husking rolls respectively-of a corn shredding and husking machine, of an inclined headboard arranged parallel to and immediately in front of the feed-rolls, the upper edge of said headboard being connected by. means of substantially horizontal links if to a stationary frame,

ing the upper edge of saidv headboard to a stationary frame, a movable inclineds apron hinged-to thelower edge of said headboard, and means forimpartinga rotary movement to said apron at its upper. edge, substantially as described;

3. The combination in atmachine of the class described-,of feedtand husking rolls respectively anzinclined headboard;anrangediparalr lel to-and immediately. infront, of: the feed& rolls, horizontallinksi for pivotally connecting the upper edge of said headboard; to, a stationary frame, a movable inclined. apron hinged to theloweredge of said headboard, means for imparting a rotary movement to said apron at its upper edge, links for supporting saidapron at itslower; edge andasuzp plemeutal apront'y hinged to the loweredge of said firstnam edtapron', substantially. asdescribed.

In testimony whereof I have signed this specification, in -the presence of two subscribing witnesses, this 1st day of March, 1900.

ALBERT VAN' NESS.
