UNITED STATES WILLIAM SEWARD FAIR-D, OF CHICAGO, ILLINOIS, ASSIGXOR, BY hIESNE BAIRD CORN HUSKER UO.

PATENT oF-FIonf ASSIGNMENTS, TO

conN-HUsxmG MACHINE.

To an whom it may concern:

Be. it known that 1, Hunt SEWARD BA1RD,3. citizen of the United States,residing at Chicago. county of (ookfand State of Illinois, have invented certain new and useful Improvements in Corn-llrisking Machines, of which the following is adescri ition.

My invention relates to that general class of devices known as harvesters and to that particular class employed for harvesting corn by separating the cars from the standing stalks and the husks.

The object of my invention is to produce a convenient, efficient, and economical device of the kind described, one that may be de pended upon to thoroughly clean the field even where a portion of the corn is down.

To this end my invention consists in the novel construction, arrangement, and combination of parts herein shown and described and more particularly pointed out in these claims.

tied driving arrangement of the down corn lifting mechanism. Fig. 24 is a detail from Fig. 23, and Fig. 25 is a plan View of the driving mechanism shown in Fig. 23.

My device asshown in the drawings, con- "sists of anydcsired number of supporting wheels, a frame mounted upon the wheels and adapted to properly support the various parts of my device in suitable cooperating position, a series of cooperating mechanisms 5 each adapted to operate successively upon each stalk of corn or the ears after being detached therefrom, and means for attaching horses or otherwise propelling the device about afield when in operation.

In the form shown four supporting wheels are employed, the wheels 1-] at the forward end of the frame 2 being each mounted in a. suitable yoke 25 rigidly attached to-the frame. The yokes 4% carrying the rear wheels 55 are each rotatably at-tached to a plate or turntable 6 which is in turn rigidly attached to the frame 2 thus providing for guiding my deviceby changing the position of the yokes 4 upon the plates 6. Any suitable means 3 may be employed to control the position of the yokes 4 to guide the mechanism. As shown an arm 7 is provided upon each yoke and connected by means of a rod 8. A. shaft 9 is rotatably mounted in a convenient posi- 35 tion upon the frame 2 and provided with a hand wheel 10 at its upper end and with an arm 11 at'its lower end, the free. end of the arm 1.1 being connected to the rod 8 by means of a link 12.

The series of cooperating mechanisms consists, first in means adapted togather thestalks together and guide them into the succeeding portion of my device in suitable position, next means for removing the ears and 5 husks from each stalk, then delivering the ears and husks'to mechanism for removing and separating the. cars from the husks, and lastly means for discharging the clean cars from the machine. may be employed toga-titer the stalks and direct them into suitable position in the machine. As shown a pair of slightly conical reels or rollers 14-1-1 are. provided for each row of corn with their axis substantially parallol and inclined backw-ard as shown. The lower end of each roller is prei'erablv sup ported upon a suitable shoe 13 so formed that when carried close to the surface ofn.

field its points will pass under an stalks of 'Anv suitable mechanism 100 and guide the same into the s ace between the rollers 14 and against the ower portion of one or the other of the pair.

As my device is advanced through a field the rollers 14 are rotated in the direction indicated on the drawings and by engaging with the stalks tend to raise any down stalks into a vertical position. To increase this tendency I preferably provide a spiral rojection 16 upon the surface of each roller. This portion of ny device also serves the purpose of gathering the grain and directing the same into the succeeding mechanism in case the machine is not accurately guided on the rows or where the distance between the rows does not accurately correspond with the spacing of the machine. The shoe 15 is carried by suitable bars and braces 17, 18, and 19 which serve to assist in supporting the succeedin; mechanism of my device.

Any suitable means may be em loyed to rotate the rolls or reels 14. As sliown the shafts 20 are extended beyond the upper end of the rollers and provided with suitable bearings rigidly atta hed to the frame 2 with a sheave 21 connected by means of a belt or equivalent means 22 with a sheave 80 driven by' suitable gearing 32 32 from the main shaft 2-4. Each pair ot reels 14 are thus independently driven from the shaft 24 as clearly shown in Fig. 3.

In the modified form of my device shown in Figs. 23, 24, and 25. bevel gears 21 are provided upon each shaft 20 cooperating with gears 21-21 upon a cross shaft 23 mounted in suitable bearings upon the frame 2. The shaft 23- is also provided with a sprocket 25 connected by suit-able chain or equivalent means 26 with a corrcs ending sprocket 27 connected to the forwar wheels 1 of my device.

It is evident that in the last described form the rotation of the reels 14 will bear an accurate relation to the forward movement of my machine. The stalks after being raised by the reels 14 are engaged by the snapping rolls 28. These rolls are substantially cylindrical in form and slightly conical at their lower ends with their axe-s substantially parallel to the gathering reels 14 :1 nd ado )ted to be rotated in the direction indicatm The rolls 28 are arranged in pairs and so adjusted that while the stalks may pass between them the ears upon the stalks cannot and will therefore be snapped oil'ns they arrive a the rolls. This portion of the device may be arranged in any suitable manner. As shown the lower bearings for the rolls 28 are attached to the lower extremities of a yoke 29 attached to the frame 2, a ba 30 being provided extending from the bar 17 to the inner face of the bearing 31 to serve as a guide to accurately direct the stalks into the space between the lower ends of the rolls 28. Any

Samoa suitable means may be provided to drive the snapping rolls 28. As shown the bevel gear 33 is mounted at the u per end of the inner roll 28'which is preferab y slightly lower than the outer roll to which it is rotatably connected by means of the spur-gears 33 33, by this arrangement it w ill be noted that as the ears are snapped from the stalks they are directed towards the central portion of the machine where a suitably formed boot or receiver 34 is rovided to receive them.

Any suita le additional means may be revided to insure the discharge of the dctac ed .LI'S into the receiver 34. In the form shown a vibrator is provided above the outer roll of each pair of snapping rolls, adapted to engage the ears and force or knock them inward. This vibrator consists of a member 35 connected near either end by means of links 36, and 36 to the frame 2 and yoke 29 re spec'tively. A shaft 37 is rotatably mounted in suitable bearings 38-38 upon the frame 2 and provided with an arm 39 for each vibrator. Suitable means are rovided to partly rotate the shaft 37 and t us oscillate the free end of the arm 39 which is connected by means of a link 40 to the member By 7 this means the member 35 is moved both longitudinally and transversely above the outer sna -ping rolls 28 thus beating the ears upon stal and tending to force the cars as soon as detached inwards toward the boot 34.

Any suitable means may be employed to remove the ears from the boot 34 and deliver the same to the hopper or chute 41. In the form shown an elevator 42 is provided for this purpose the head shaft 43 of which is driven by any suitable means from the main shaft 24 for exam 116 by the sprocketchain 81. Any suitable iorm of elevator may be employed for this purpose.

As shown the back side of the boot 214 is extended upward forming a back or bottom 44 the sides 83 of which may be employed to support the head shaft 43. In the form shown these sides are each formed of two parts connected by bolts or equivalent means 8-1 each positioned in a slotted opening so that the sides may be slightly extended or shortened to adjust the pwition of the head shaft. Suitable chains or'ek uivalent means 45 are provided at each side of the bottom 44 connected at suitable intervals by means of lli hts or bars 46. Suitable guide sheaves or idlers 47 and 48 bein prov id d to so direct the chains 45 that t 1e flights 46sweep in close proximity to the bot-tom of the boot 34 and up the back 44 thus carrying any. ears in the boot upward to the upper end of the back where they fall by gravity into mt. chute n1" hopper -11 and thence to the mechanism for removing the husks from the ears. Any suitable mechanism may be employed for this pur ose. As shown one or more pairs of slig tly inclined rolls 49 are provided of such size and so adjusted that the husks upon an ear lying upon the rolls will be engaged and torn away without injuring the ear or breaking the kernels of the grain.

The several husking rolls may be rotated by any preferred means, in the form showh a gear 50 is provided at the upper end of each roll, and rigidly attached thereto, of suitable size to mesh with the corresponding gear upon the next adjacent roll, a pair of sprocket Wheels 51 and chain 52 or pther suitable means being provided to transmit power from the shaft 24 to the train of 'gears50-50.

Preferably the ears are delivered near the upper ends of the rolls 49 and pass by gravity to their opposite ends during the husklng op- .eration. desired, however, any desired number of rotary brushes or bristle rolls 53 may be arranged above the rolls 49 as shown in Figs. 20 to 22 inclusive the bristles upon the several brushes being referably arranged alternatel in right and lei t hand 5 irals so that as t e brushes are rotated, y means of suitable sprockets 54, chain 54' gearing 55, and sprockets 5656 and chain 57 from the main shaf t 24, the engagement of the bristles with the ears will not only tend to move the ears toward the discharge end of the bushing rolls but will'also tend to rotate the ears first in one direction then in the other as it encounters the successive brushes and also to,raise the husks from the kernels so as to insure the complete removal of all husks from each ear.

49 by a trough or slide '58 to an elevator 59 preferably extending over the side of my device and provided with a spout 60 to direct the clean cars into a wagon or other suitable receptacle. The elevator 59 is also prefer ably driven bv means of suitable sheaves 6.1, 62, and a belt orother suitable means 63 from the main shaft 24'. Thus in the preferred form of my device all the mechanism is driven primarily from thcma-in shaft 21 which may in turn be driven in any convenient manner. In the-form shown an inde-' pendent gasolene engine, or other suitable motor 64 is mounted upon the frame 2 and connected in any manner desired, as by s rockets 65-65 and chain 66 or other suitaole transmission appliance, to the shaft 24.

An desired means may be employed to prop e my device when in operation. As

shown a portion- 67-67 of the frame 2 exz-nds to the rear and is there provided with suitable means for attaching nurses or other draft animals which in a manner push my device before them thus avoiding any damage to the unharvested corn from breaking down and trampling, obviously this is a great advantage as my device is thus enabled to operate in absolutely undisturbed grain.

Ordinarily it is difficult to keep draft animals pulling evenly with their driver seated The clean ears pass from the husking-rollsat their heads.- To overcome this inconven-, ience a movable whip socket 68 is provided for each animal arranged to securely hold a small whip, or switch, so that a move ment of the socket will bring the whip sharply down upon the back or flank of a draft animal, a spring 82 or other suitable means being provided to normally hold each socket so that the whip contained therein is retracted.

A foot pedal 69 is provided for each-whip socket andconnected by means of a rod 70 or other suitable connector to the operating arm 7 i of the socket so that a driver sittin in the seat 72 by the operation of ,a footpeda l may instantly spur up any member of his lag ing team.

fiaving thus described my improvement it is obvious that various immaterial modifications may be made in my device without depal-tin from the spirit of my invention,

ence i do not wish to be understood as limiting myself to the exact form or constru tion shown.
