CORN HUSKING AND CLEANING MACHINE.

SPECIFICATION forming part of Letters Patent; No. 307,339, dated October 28, 1884.

Application filed March :20, 1884 (No model.) i

To aZZ whom it may concern:

Beit known that LS. MILFORD SOHINDEL,Qf Hagerstown, in the county of Washington and State of Maryland, have invented certain new and useful Improvementsin Corn Husking and Cleaning Machines; and I do hereby declare that the following is a full, clear, and exact description of the invention, which will enable others skilled in the art to which it appertains to make and use the same, reference being had to the accompanying drawings, and to the letters of reference marked thereon, which form part of this specification.

My improvements relate to that class of inventions known as corn husking and clean ing machines, and have for their object to supply an apparatus possessing in a much simplified manner all the attributes necessary to a full and free operation, and one that produces with greatest rapidity and effectiveness the most practical results. Prominent among results is that the husking is accomplished so thoroughly as to prevent to a greater. extent than heretofore the escape of husks and other debris to the cleaning-rolls, thus permitting such rolls to operate more satisfactorily in picking or removing the silk that naturally adheres to the car than otherwise has been done. Further, the means by which the delivery of the corn from the husking-rolls to the cleaning-rollsjs accomplished renders the husking and cleaning continuous and perfect.

With the advantages set forth in view, my invention consists in the construction and (30111- bination of parts, substantially as hereinafter described, and pointed out in the claims.

Referring to the annexed drawings, Figure 1 represents, with the feed and delivery boards removed, a top plan view of an apparatus embodyingthe features of my improvement. Fig. 2 is a side sectional elevation thereof on the liney y, Fig. 1. Fig. 3 is an end elevation showing in section on the line a: m, Fig. 1, the picking -rolls and cleaning devices therefor and the sides ofthe frame inelosing such rolls, also showing the feed-board in elevation, with its forward end partly broken away and in section to more clearly illustrate its construction. Figs. 4 and 5 are detail views, respectively, of the picking-rolls and husking-rolls.

while being subject to the action of the picking-rolls. Fig. Sis a detail of the sliding journal-boxes.

Reference being had to the several parts by letter, A represents .the framework of the machine, the same being of any approved construction. Mounted on such frame-work across the top, and in suitable bearings, a a, are corrugated differentially-rotated rolls B 1), their points of support being in the same vertical line, and the one of largest circumference being preferably uppermost.

To one end of the shaft of the upper corrugated roll is a drive-wheel, 1, by which the machine is driven from any suitable power,

while at the opposite ends of the shafts of both are different-sized cog-wheels 2 3, which mesh with each other, and by which the motioncommunicated to roll B is transmitted to thelower one, 6.

Carried on that end of the shaft of rollers b 7 5 corresponding to that end of the shaft of the upper roll that carries the drivewheel is a beveled gear-wheel, 4, which meshes with a similar wheel, 5, on the end of arotating shaft located beneath, for a purpose to be described hereinafter.

Situated beneath the husking-rolls B b, and somewhat beyond one side thereof, is an inclined vibrating trough, O,,which receives the corn as it is torn from the stalk and delivers 8 5 it to the cleaning or picking rolls.

It is very desirable in machines of this character, where the picking rolls are parallel with the husking-rolls, tohave the corn delivered to said picking-rolls lengthwise there with, so as to permit the corn to be more read: ily received by them and cleaned. If the ears are delivered thereto in a jumbled mass, the working of the rolls is retarded, and break-.

age of some of the operative parts is theconsequence. This is a common defect in many machines now in use, and I propose to over come the same by forming the bottom of the inclined trough O with slats 0, so that the corn,

when it falls therein, is induced to take a'di- 10o rection coincident with the length of the picking-rolls, and thus be received into their workingbite and thoroughly cleaned. This trough O is supported at its upper end in a hole in the frame A (see Fig. 2) by a pin, 0, which moves in and out of said hole as the trough is vibrated. The lower end of the trough is loosely supported from the frame or sides (Z d of the boxing inclosing the picking-rolls by straps or pendants 0 0, thus permitting a free vibrating motion. This motion is obtained by means of a cam, c, that is carried by a rotating shaft, D, located in and borne by the frame beneath. and at a point near the center of the trough. The shaft 1) is supported in line with the bottom of the trough, and carries at its outer end the beveled gear-wheel 5, that receives its motion from wheel 4, and is thus rotated. The ends of the cam 0' come in contact successively with lug con the bottom of the trough. It is evident, however, that other means than those just described could be employed for the same result. The inner end of shaft D carries a cog'whecl that is permitted to rotate in a true vertical plane by virtue of a joint, f, in said shaft. This wheel is also secured to the shaft of the outer picking-roll, (represented byx, Figs. 1 and 4,) and constitutes one of and meshes with anotherone of a train of cogs, g, carried by the inner ends of the shafts of the picking-rolls E, and by which they are operated to revolve in pairs in opposite directions, as indicated by the arrows, Fig. 4. One roll ofeach pair of picking-rolls is preferably provided with pins, or bearded, as it is commonly called, and the other is of smooth surface in order to move effectually clean the ears. any suitable material, and have their bearings in boxes s,that slide in slots or grooves in cross-beams (5 and 7. (See Fig. 8.)

Extending between the non-working bites of the picking-rolls above and lengthwise of the same are square strips h, of iron or other suitable material, which constitute cleaning devices for said rolls. They are loosely secured at their ends by pins or screws that pass through elliptical slots at in the cross-beams 6 and 7 of the frame, or in the cleaners thenr selves, see Fig. 1,) which allow them to turn and rise slightly at either end to yield to masses of silk and husks that might accumulate and retard the working of the rolls. Their function is to gather the surplus silk from the rolls as the corn is operated upon between their working-bites, and cause it to be precipitated between said rolls to the ground beneath. In addition to this function, however, should the corn as it is fed to the rolls strike upon them, it is caused to glance off to one side or the other by virtue of their contour, and thus assist to prevent the non-cleansing of a single car. They are preferably square in cross-section, and an angle formed by two of their sides rests between the rolls, as shown in Fig. 4. Their two under sides are preferably bearded, as shown in detail, Fig. 6. This They are made of figure shows a slight deviation from the crossseetion shown in Fig. 4.; but I consider such form clearly within the scope of my invention.

Connected to the trough G at its lower end by a rod, 2', passing therethrougl1,are two, three, or more devices, F, that are caused to vibrate with each vibration of the trough. Their outer ends are loosely suspended by straps Z, that are secured to strips m, extend ing across to the sides (I (7, in order to allow said ends to rise and fall. These devices serve two functions, to wit: First, being serrated or otherwise roughened on their under surfaces,

and having imparted to them a vibrating 1notion, they act to gradually impel the corn forward to the delivery end of the picking-rolls, while it is rotated by their cleaning action; second, in the event of an ear of corn, while passing over the picking-rolls, being thrown upon end, hese devices at first slightly yield upward b virtue of their flexible support atthe outer ends, and then by their continuous vibrations they act to again force it down without breakage or stoppage of any part of the machinery. In Fig. 7 I have shown these de vices as being one solid apron, which would serve with good results in some instances; but in practice I prefer to use them in the form just described.

G represents the feed-board for the stalk to the huskingrolls, which is formed at its end nearest such rolls with an opening, Z, extending entirely across for the passage or drop of the corn as it is pinched off. An inclined board (see dotted lines, Fig. 3) is situated justbeneath the lower husking-roll, to guide or direct the corn, as it falls, upon the trough C.

II represents the delivery-board for the stalk after its passage through the huskingrolls.

In Fig. 5 are represented in dotted lines boxes 8, for the shafts of the picking-rolls, which slide in longitudinal grooves or slots in the cross-beams 6 and 7. At each end of the beams is a spring, 2, which bears between the sides of the end boxes and a small disk, 8, and whose tension is regulated by a set-screw, J. The purpose of these sliding boxes is to allow the picking-rolls to break gear and yield either way to any obstacle that otherwise would retard their operation, and after such obstacle has passed through to be again forced into gear by the resiliency of the springs. I11 this figure a nest of but four rolls is shown, which would only require a spring at each end of the supports in which their bearings are held; but of course in a nest of six, as in Fig. 1, a spring would have to be located and arranged inter mediate of these. I11 said Fig. 1 these sliding boxes are not illustrated, in order that the other connections of my apparatus may be shown.

The operation is as follows: The stalk c011- taining the ear of corn to be husked is placed upon the feed-board butt foremost and ad- .vanced against the husking corrugated rolls B b. The rolls seize the stalk, rolling it through upon the delivery board H. The ears of corn, upon reaching these rolls, strike the larger one butt first, and are bent or turned downward at an angle, while the pull upon the stems is in a straight line, and is a gradual, even, and thorough tearing one. The husked ears drop into the vibrating trough G, where they are made to assume a direction coincident with the length of the picking-rolls by falling into employment of the corrugated rolls operated at diii'erential speeds I obtain with a much smaller expenditure of power greater results in agiven time than are accomplished by many machines now in use.

Having thus described my invention, what I claim is 1. The combination, in a corn-husking machine, with the corrugated bushing-rolls and means for revolving the same, of the inclined slatted trough and the means by which it is vibrated, the picking-rolls, and the serrated devices F, all constructed and arranged sub stantially in the manner described.

3. The combination, in a corn-husking machine, of the inclined slatted trough, supported at its ends as described, and the means by which it is vibrated, of the picking-rolls, their sliding boxes, slotted supporting cross-beams in which said boxes are held, the serrated de vices F, the rod 1 pivotally supporting their inner ends, and the flexible straps supporting their outer ends, substantially as shown and set forth.
