To all 'whom'it may concern:

Beitknown' that I, WILLIAM R. Knivwann, a citizen ofthexU-nited States, residing at Airtelhin the county of Marshall and State a of Kansas, have invented a new and useful HuskingQ/Iachine, of'which the following is a specification. i a

This invention relates to husking machines, it being morejparticularly an attach-' inent adapted to be placed on a wagon or other yehicle, means being provided whereby the husking mechanism can be driven by one or more Wheels of the vehicle to which the structure is attached. 1

A further object is to vprovide improved means for husking the corn, said means including a novel arrangement of husking rolls and means for conveying theears positively alongthe rolls so as to discharge them lflltimatelyfinto an elevator provided there or. c 1

A further object is to provide means for collecting the loose grainsofeorn anddirecting them into the elevator so'that they will be discharged into the vehicle with the ears of corn. i y With the foregoing and other objects in view which will appear as the description proceeds, the invention resides in the combination and arrangement of parts and 1n the details of construction hereinafter described and claimed, it being understood that changes in the precise embodiment ofthe invention herein disclosed, can be 'made within the scope of what is claimed, without departing from the spirit of-the invention. i t. r

Referring to the figures by characters of reference A designates the body or box of a vehicle having the usual supporting wheels B. A sprocket 1 is adapted to be bolted or otherwise secured to the inner side ofone adapted to be secured to the inner side of v the other wheel B. Secured to the running gear of the vehicle in any suitable manner,

here being shown extended under the body A whlle the upperarms are extended along the sides of the body, both arms being attached to the body by suitable straps 4: extended under the body and across the frame members and then hooked into engagement with the upper edges of the sides of the body A. This structure has been clearly shown in Fig. 3. y

The two frame members 3 carry the mechanism constituting the present invention. These frame members are connected,

back of the body A, by a cross beam 5 on of the wheels B while another sprocket 2 is are side frame members 3, preferably U-' shaped, the lower arms of the frame memthe end portions of which are journaled H vertical shafts 6 and 7 respectively, eachof these shafts carrying a sprocket 8 and the two sprockets being engaged byan endless conveyer belt 9 which can be in the form of a chain, there being outstanding fingers 10 of corn to be acted upon; The flights of the conveyer extend transversely of the machine and back of the body A, the forward flight being close to'and parallel with a husking roll 11 mounted in bearings 12 supported by the frame members 3. i

Thefingers on the forward flight of the conveyer extend over the husking roll 11, as shown in Figs. 1 and 2 and the husking roll 11 isprovided either with longitudinal corrugatlons or with spiral rlbs, as preferred, this roller receivlng motlon from intermeshing pinionsll' one of which is mounted on "upon the conveyor belt at distances apart slightly greater than the length of the ears the shaft of the roll 11, the other of which (see Fig. 9) is carried by a shaft 100 supported in any appropriate manner uponthe frame of themachine, the shaft 100 having a sprocket wheel '18 receiving a chain 17.

The chain 17 extends' forwardly along one side of the body A and is mounted, at its frontportion, upon a sprocket 19 carried by the short arm 20. of a bell crank lever 21,

the long arm' of this lever-being extended upwardly beyond the Side of the-body A so" as to be manipulated conveniently. .7 This long arm of lever 21 can be locked in any suitable manner so as to be held against movement and when sprocket 19 is in its lowermost position, the lower flight of chain 17 is held in engagement with the upper portion of sprocket 1 so that, as the wheel B rotates, the chain 17 will be actuated and motion thus transmittedto the roller 11.

The roller 11 1 drives a second roller 13 which is journaled in bearing blocks 14 slidably mounted in guides 15. The surface'of roller 13 is formed of rubber or other suitable soft material designed to friction- A ally engage the roller 11' and springs 16 bear against the blocks 14 so as to press roller 13 yieldingly against roller 11 at all times. The. roller 11 therefore constitutes the means for driving the roller 13 and in turni s adapted to be driven by the chain 17 which engages the sprocket 18 secured to the shaft 100. Another roller 22 is supportedabove and normally contacts with the roller 13, this roller 22 being jonrnaled in bearings 23 carried by supporting springs 24, the springs being so arranged as to press roller 22 yieldingly against roller 13. Roller 22 is preferably provided with a soft periphery made up of rubber or other suitable material designed to .frictionally engage roller 13 so that, during the rotation of said roller 13, the roller 22 will be actuated. The direction of rotation of the various rollers has been indicated by arrows in Fig. 1. An

arcuate shield 25 is arranged to bridge the space between the rollers 22 and 11, there beinga sufficient space between this shield 25 androller 11 to receive the fingers 10 of the c'onveyer 9;

A trough 26 is supported under the rollers 11, .13 and 22, this trough being inclined downwardly'toward one side of the machine and being provided, at its top, with a grate 27 on which the husks and any loose grains .of cornare adapted to fall from the rollers of the :husking mechanism. The grate is so 7 inclined that the husks will-slide therefrom causing the material to move upwardly to an outlet spout 31 which extends from .the

upp.er. end of thecasing 28 and discharge into the body A. I Another spout. 32 extends fromnnder the rollers 11, 13 and 22 at one,

end andnserves to direct the ears of corn from the ends-of-the.rollers into the elevator casing 28l Thus ;it.- willbe seen that the; elevator 29 serves not only to lift the loose grains of corn up to the spout 31 but also to lift the husked earsto said spout; The V elevator 29 is driven. by novel mechanism provided for that purpose. The said mechanism includes a shaft 33 onwhich thelelevator 29 is mounted, this shaft being pro- ;videdwith a gear, constantly meshing with another smaller gear 35 secured to a shaft 36. Said shaft 36 has a sprocket" 37 secured thereto and engaging thesprocketiis' a drive chain 38 engaging a sprocket 39021.1.- ried by a bell crank lever 40. One arm of this bell crank lever is connected by a rod l1 to a shifting lever 42 fulcrume'dzu'ponone side of the body A, any suitablemeans being provided for lockingthisleverjagainst movement: It willbe: apparent thatawhen the shiftinglever isinoved. in one direction,

sprocket 39 willbe shifted doWnwardly-,-thusi bringing the lower flight of chain 38 into engagement with the sprocket 2 so that, as the vehicle moves forward, motion will be transmitted from sprocket 2'to chain 38 and thence to shaft 36 and, thro'ughxgears 35 and 3A-t0 shaft 33 and elevator 29; By shiftinglever 4:2 in the-opposite direction,

however, the chain 38is.lifted out of en gagement with the-sprocket 2 and the operation of the elevator is thus stopped.

A sprocket 43 rotates with shaft 33: and is engaged by achain 4A which, in turn,flengages a sprocket l5 secured 'to a shaft/'16 which is journaled in one of the frame members This shaft 456 has a bevel gear 47 which meshes with another bevel gear 48 secured to the lower end-of shaft 7; Thus it will be seen that as longas the elevator -29 is in operation, motion will be'transmitted to the conveyer' 9 which receivesits motion from the shaft 7. I

In order that the-husking rolls may} be properly supplied with ears for huskin'g, a

delivery spout 46 is fixedlymounted on one.

of the frame members '3 and extends upwardly and laterally therefrom. A trans?- verse shaft is; extendedlaterally from this? shout, as shown at47Land hasa sprocket 48 secured to it and receiving? motion through a chain 49, from a sprocket 5O which rotates with thenshaft' 100. Shaft 47' has an elevator casing 51 hungtherefrom and mounted in this casing isan ele vator- 52 extending downwardly, and .for-* wardly. The lower end ofthe elevatorcas ing is supported by a lifting, rod; 53 connected, as-by: means of a link 54, .toone. arm 3 55 of a bell crank lever 56, the other arm of the bell crank lever being extended abovev the body A andv provided with any suitable, n eansl wherebyit' can be.- locked against movement. Obviously by means of .this lever 56 thelower end .ofthe-elevator casing .can be swung upwardly orfldown wardl'y' so; as to be brought .to any 'desired distance;

1,1 mess;

from the ground. Arranged along the outer side of theelejvatorcasing 51 are snapping rolls 5'7 and.58,} respectively, the roll,58 be- That ,portionof the elevator casing 51 at one sideaof therolls 57 and 58 is cut away so that thecorn when snapped from the stalk will be free to fall laterally from the rolls and onto the elevator 52. Gathering fingers 60 diverge from the lower ends of the rollers, as shown in Fig. 3 and operate as ordinarily to collect the stalks so that v they .will be fed into the pass between the snapping rolls 57 and 58. The two snapping rolls rotate in opposite directions, this being due to the fact that each of themlias a ear 61 at its u oer end the two ears b 7 b meshing. One of thesnapping rolls 58, has a shaft 62 extending upwardly therefrom and provided with bevel gear 63 which mesheswith a gear 64. secured to shaft 17.-

From the'foregoing description it will be apparent that when the machine is drawn. forward and-'thel chains 17 and 38 are in 1 engagement with their respective driving sprockets, motion will be transmitted to the various parts of the mechanism. Thusthe stalks will be directedintothe pass between the snapping rolls 57. mass and these rolls, which can be either corrugated, plain, or formed with spiral ribs, will engageothe stalks and breakthe ears therefrom, The cars will. be shifted laterally by the rolls57 and 58 so as tofall onto the elevator 52 which elevator will carry them upwardly and discharge them into the spout 46T and this spout, in turn, will direct the ears onto the feeding endsof thehusking rolls. The rolls 11 and 13 will cooperate to remove the husks from the ears" and direct the husks downwardly onto the grate 27. During this .actionf'of the rolls 11 and 13 the fingers on the conveyer 9will engage the ears and drag them longitudinally ofthe rolls, the rotating roll 22 serving to maintain the ears in position between. the fingers 10 on the con veyer. When the ears reach the discharge ends of the husking rolls they are directed into the spout 32 and thence onto the elevator 29 which carries themto the wagon body in the manner hereinbefore described. It has been found that by providing a conveyer in connection. with husking rolls such as disclosed, the operation of removing the husk is more efficiently performed than where the ears are shifted along the rolls solely by gravity. Furthermore by utilizing one husking roll which is operated solely by frictional engagement with the other'huslc ing roll,the first named roll is free to stop rotating should the ears become wedged be tween the rolls and, consequently, danger of *roll 63.

crushing the cars is reduced to the mini-:

. Instead of driving the husking rolls in the manner hereinbefore described and as illustrated in Fig. a, .mechanism such as llustrated in Fig. 6 can be utilized. By referring to this figure it will be seen that a husking roll 61 is driven as before described,

and frictionally engages the husking roll 62. This husking roll is driven frictionally in the manner hereinbefore described but a worm 63 rotates therewith and constantly meshes with a worm gear 641 secured to a shaft 65. Thls shaft 1s Journaled on an arm 66 which is fulcrumed on the shaft 67 of roller 62, and a bevel gear 68 rotates with shaft 65 and meshes with another bevel gear 69 secured to a shaft 70 journaled inthe arm 66. A sprocket 71 rotates with shaft 70 and transmits motion through a chain 72 to a SPl'OCh'Gt 73 which is connected to the roll 7 1, said roll being journaled in an arm I T5 formedintegral with or fixedly connected to thearm 66. Thus it will be seen that by shifting arm 75 the roll 74: can be adjusted toward or from the roller 61 without, however, disturbing the mechanism employed for transmitting motion from roll 62 to the In this modified form a shield 76 similar to the shield 25 is extended from thearm 75 so as to bridge the space between the rollers 61 sand73.

Importance is attached to, the fact that the I mechanism herein described can be applied readily to a wagon alreadyin use and by drawing the wagon along one side of a row, the corn growing in the row will be quickly and efficiently gathered and husked, the husks being discharged onto the ground and the ears directed into the body of the wagon. It is to be understood that the roller 22 shown in Fig. 4, can be adjustably mounted on the spring 2 1 by providing longitudinal slots 24 in which the bolts 23', which secure bearings 23 to the springs 24, can be adjustably mounted.

By referring to the seen that the husking rolls 11 and 13 form the bottom of a trough the sides of which are made up of the roll 22 and the conveyer 9 respectively. p

In Figs. 7 and 8 the parts remain as shown in Fig. 6, corresponding parts being designated by the same numerals with the suflix a. In this form of the invention, a spiral roller 101 formed in one or more sections and supported in any convenient manner upon the frame work of the machine, coacts with the ear of corn E to advance the same longitudinally of the rolls 7%, 62 and 61.

The roller 13, being covered by a facing of rubber or the like, gives a cushioning grip on the husk, when used in connection with the corrugated roller 11.

Attention is called to the fact that the drawings. a will be shield which bridges the space over the husking rolls 11 and 13 is for the purpose of preventing the ears of corn from being thrown upwardly away from the husking rolls while the rolls are stripping/the husks from the ears of corn. In other words the ears of corn are held down on the husking rolls and the ears are caused to rotate while being moved longitudinally, this rotation being facilitated by roll 22 so that all of the husks will be removed from the ears.

The ears are under absolute control at all times while being conveyed along the husking rolls.

What is claimed is 1. A husking machine including a receptacle for hushed corn,- an elevator at each side of the receptacle, and husking mechanism extended between the elevators, one of said elevators constituting means for elevating ears to the husking mechanism and the other elevator constituting means forconveying husked ears to the receptacle, the husking mechanism and the elevators being supported by the receptacle.
