Referring to the drawings, 1 and 2 represent supporting-frame members having their rear ends mounted upon a suitable axle havraftanism at its receiving end. Fig. 12 1s a sec- "ing carrying-wheels 3, journaled thereon, and

frame 9, having side members 10 that extend,

upward, rearward, and outward and have their upper ends secured to vertically-arranged framemembers 11. Connected with the upper end of the elevator-frame 9 is the -upper end of a downwardly and rearwardly' 'extendin frame 12, havin its rear end connected with and supported by the rear ends of the frame members 1 and 2. Pivotally connected with the rear ends of the frame members 1 and 2 is the lower end of an elevator-chute 13, that is adjustable about its pivotal connection in a manner to cause its delivery end to be adjusted from a lower to a higher plane, and 14 represents .a hoisting mechanism mounted u on a vertically-arranged frame 15, secure to the frame 12 and the frame members 1 and 2 and operative in a well-known mannerto adjustably support the delivery end of the.elevator-chute 13.

Pivotally mounted above the lower end of the elevator-frame 9 is the upper end of an elevator-frame 16, that extends downward and forward to substantially the horizontal plane that the carrying-wheels rest upon and then horizontallyforward and having its horizontal portion 17 (provided with outwardlydiverging side an end portions forming a receiving-hopper 18. The elevator-frame 16 may be swung about its pivotal axis in a manner represented by dotted lines in Fig. 2 for transportation purposes.

Journaled at the forward end of the horizontal po'rtion17 of the elevator-frame 16 is a shaft 19, and operatively connected therewith is an endless carrier comprising sprocketchains 20 and 21, connected y means of bars 22, that rest upon the bottom of the receiving-hopper and operate to move theears thereupon, the operative ply of the chains being prevented from rising by means of suitable guards 23, secured to the horizontal portions 17 and overhanging the chains, the op-. posite end of the end ess carrier being operatively connected with a shaft 24, journaled in the upper. end of the elevator-frame 16. The endless carrier when'in operation delivers the unhusked ears into a conductingchute 25, mounted upon the fixed frame members of the machine and adapted to de-- liver'the ears to the elevator 9.

J ournaled at the lower end of the elevatorframe 9 is a shaft 26, and at the upper end thereof is journaled a shaft 27. Secured to these shafts are toothed wheels 28, having the outer ends of their teeth formed concentric with the axis of the wheels both circumferentially and longitudinally thereof, and 29 are sprocket-wheels having recesses 30, adapted to loosely receive the teeth ofthe wheels 28 in a manner to allow a relatively oscillatory movement between the wheels and sprockets. Sprocket-chains 31, having carrying-teeth 32 at intervals thereon, operatively-engage with the sprocket-wheels.

The elevator 9 is wider at its delivery end than at its receiving end, and the carrierchains operate in laterallydiverging upwardly-inclined planes for the purpose of separatin the ears and conveying'them in separate les to the husking-rollers 33, that are operatively arranged in the frame 12.-

The ears are received by a downwardly-inclined plate 34, having angularly-arranged V-shaped'members 35, secured thereto and forming with the plate a series of trough-like conductors with flaring mouth portions adapted to conduct the several files of ears to separate pairs of husking-rollers in the series. The husked ears are delivered from the husking mechanism to a receiving-hopper 36, secured to the lower end of the elevator-chute .13, havin a shaft 37- journaled at its lower end, whic operatively engages with a carrier-chain 38, provided with suitable flights 39, adapted to convey the ears to any suitable receptacle.

Motion is transmitted to the operative mechanism in the following manner: Mounted upon the main frame intermediate its ends are two cross-shafts 40 and 41,'the shaft 40 having its outer end adapted to engage with any source of power by means of a uni- 8 versal cou ling 42, the inner ends of the two shafts being journaled in a semicircular bracket 43, secured to a transverse frame member 44, and and 4.6 are bevel-pinions. secured to the shafts intermediate the bearings and meshing with a bevel-gear 47, secured to a vertical shaft 48, journaled in a portion of the semicircular bracket 43. Secured to bracket 43 and adapted to be adjusted concentrically therewith is a journal- 5 support 49, pivotally mounted upon the axis of the bevelgear 47 and secured to the bracket by means of bolts passing through any of aseries of concentric openings 50 in the bracket. Journaled in the support 49 is zoo a radially-disposed shaft 51, having a driving-pulley 52, secured to its outer end and a driving-pinion 53 to its inner end and engaging. with the bevel-gear 47. The drivingpulley may be connected with any source of 105 power by means of a driving-belt, and by adusting the shaft 51 andits sup ort about the axis of the gear-wheel 47 t e driving power may be received from different directions within the limits of adjustment of the x to su port upon the semicircular bracket;

oosely mounted upon the cross-shaft 40 is a sprocket-wheel 54, having one end of its hub portion provided with clutchteeth 7 adapted to engage with a clutch member 55, 1 x 5 splined'upon the shaft in a manner to slide t ereon, and 56 is a bar mounted upon the fixed frame and movable transversely thereof and provided with an upwardly-extending forked arm 57, embracing the clutchmember 12c 55 between suitable collars thereon in a manner to cause the clutch member to partake of -the movements of the bar.

Pivotally mounted upon a transverse frame member is a vertically-disposed lever 58, carrying a spring-pressed detent opera? tively engaging with a sector'rack'59 aliid having its upper end pivotally connected f, with the bar 56 in a manner to communicate motion thereto when said lever to 13 vibrate about its pivotal axis, and 60 and 61 are oppositely-disposed hand-operated levers forming part of the vertical lever and transversely arranged relative to the machine ina manner to be convenient to the hand of the operator at either side thereof and provided with a common form of thumb-lever and link connection operatively engaging with sprocket-wheel 63, is a sprocket-wheel 67,

and 68 is a sprocket-chain connecting it with a sprocket-wheel 69, secured to one end of a short shaft 70, journaled at one end in a bearing 71, secured to the frame member 1, and at its-opposite end in a bearing 72, forming a part of a casting 73, secured to a transverse frame member 74. A vertically-arranged bearing 75 forms a part of casting 73, and journaled therein is a short shaft having pinions 76 and 77, secured to opposite ends thereof, and secured to the inner end of shaft 70 is a pinion 78, meshing with pinion 76. Pinion 77 meshes with a pinion 79, secured to a transverse shaft 80, having its ends journaled in bearings carried by a bracket 81, pivotally mounted upon the casting 73, and secured to one end of the shaft 80 is a gearwheel 82, adapted to mesh with a gear wheel 83, secured to the shaft 37 and adapted-to communicate motion to the endless carrier mounted in the elevator-chute 13, which may be swung from side to side, the bracket 81 turning about the axis of the vertical shaft mounted in the casting 73. Upon the opposite end of shaft 64 is secured a pinion 84, meshing with an intermediate pinion 85, journaled upon a stud 86, secured to a handlever 87, that is pivotally mounted upon the shaft 64 and provided with a spring-pressed detent 88, adapted to engage with a toothed sector 89 and a common form of thumb-lever and link connection operatively connected with the spring-pressed detent.

, from frame 96, mounted u on the front bolster of the transporting-true and the inner end of said shaft is j ournaled in a transverse bearin 97, forming part of a gear-frame 98, secure to the base-frame 96 and having a verticallyarranged tubular portion 99, in which is j ournaled a shaft having inions 100 and 101, secured to opposite en s thereof, the pinion 100 meshing witha pinion 102, secured to the inner end of shaft 94, and pinion 101 meshing with a pinion 103, secured to a transverse shaft 104, journaled in bearings 105 and 106,-

carried by a U-shaped bracket 106, pivotally mounted upon the upper endof the vertical member of the gear-frame 98 in a manner permitting the bracket to swing from side to side, and 107 is a gear-wheel secured to one end of shaft 104 and adapted to mesh with a gear-wheel 108, secured to shaft 24 and operative therewith to communicate motion to the endless carrier mounted in the elevator- frames 16 and 17, the upper end of frame 16 being adapted to'swing about the axis of shaft 24, as shown by dotted lines,.

and to have the hopper sides 18 rest upon the fixed support 109, having its legs secured to the sides of the frame 12. Mounted above the husking-rollers and. arranged parallel therewith. are a series of reciprocating bars 110, provided with laterally-extending earforwarders 111, having substantially pyramidal form with their bases toward the delivery end of the husking-rollers, the bars bein provided with guiding-slides 112, securet i at opposite ends thereof and adapted to slide through openings provided therefor in the end members of the "husking-roller frame. Secured to the upper ends of the side members of the frame '12 are triangular brackets 113, and mounted at the upper ends thereof is a rock-shaft 114, and depending therefrom are a series of levers 115, having their lower ends pivotally connected with the reciprocating bars 110. Motion is transmitted to the. rock-shaft by means of an eccentric 116, secured to the shaft 64, and a pitman 117, having one end engaging with.

, connected to one of the depending levers by means .of the link 120, as shown in Fig. 12.

Between the chains 31, operative to deliver the ears to the husking-rcllers, are placed bars 121, having beveled edges and arranged in a manner to form V-shaped conduits for the reception of the ears, as shown in Fi 10, and the sprocket-wheels are held dateral movement by means of the side walls 121 of the openings through the bottom boards of the elevator-frame, as shown in Fig. 13. The hearings in which the shaft 37 at the lower end of the ear-conveye'r 13 is journaled are embraced by the forked ends from operative position to a position upon the brackets when the machine is to be arranged for transporting. When the machine is arranged for operation, the unhusked ears Y What I claim as my of corn are dumped from the wagon into the receiving-hopper and the endless carrier elevates and delivers them to the supplemental carrier, having means for arranging the ears in separate files and delivering them to the inclined husking-rollers, from which they are delivered to the ear-elevator, which conveys them to any receiving-receptacle or storage-bin. V

The elevator-frame may be swung toward either side of the machine, it being connected with the bracket 106that is, free to turn about its vertical pivot-the feature of construction, as described, being particularly available when the unhusked ears are dumped from the rear end of a wagon-box,-

and, as is frequently the case, the box is elevated at its forward end by outside means, it being necessary to place the wagon in a predetermined position relative to the elevator mechanism.

o With my improved construction the receiving hopper may be swung toward one side and the wagon placed in position for dumping its load, when the receiving-hopper may be swung into position in rear thereof to receive the load. In a similar manner the elevator-chute 13 may be swung from side to side for the purpose of directing the delivery end thereof to any part of the.

storage-receptacle.
