Original application led March 3, 1913, Serial No. 751,898. Divided and this application filed July 29,

1'9'13. Serial No. 781,845.

To all whom t may concern:

Be it known that I, ANDREW J. MARK- HAM, a citizen of the United States, residing at Dana, in the county of Greene and State ofIowa,V have invented a new and useful Corn-Husker, of which the following is a specification. v v

This invention relates to corn husking machines and is more particularly adivision of an application filed by me on March 3, 1913, Serial No. 7 51,898.

One of the objects of Vthe invention is to provide improved means whereby the ears of corn may be husked, the ears, as well as all loose grains of corn, being directed to an elevator which will convey them to a wagon or other receptacle disposed adjacent the machine.

, that changes in the precise embodiment of the invention herein disclosed, can be made within the scope of what is claimed, without departing from the spirit of the invention.

In the accompanying drawings the preferred formfof the invention jhas been shown.

In said drawings Figure 1 is a plan view of the machine. Fig. 2V is a longitudinal section on line A-B Fig. 1.

Referring to the figures by characters of reference 1 designates the revoluble axle supported by wheels 2 which are adapted to rotate therewith. A frame 3 is supported by the axle and connected to the rear portion of the frame 3 is a rear frame 4. The rear end portion of the rear frame 4 has a steering mechanism 6. VArranged trans.

versely upon the rear frame 4 close to the back end of the frame 3 is aV trough 21 having an outlet adjacent one end of the machine, the bottom of the trough being inclined downwardly toward said outlet. An inclined elevator casing 22 extends upwardly and laterally from the machine at the discharge end of the trough 21 and in thls casing is arranged an endless elevator belt 23 preferably provided with cross cleats 24. The lower portion of the conveyer belt 1s mounted on a shaft 25 whichV extends forwardly' and is provided at its front end'with a gear 26 constantly meshing with a gear 27 `secured. to the aXle 1. `This gear is also provided with peripheral--sprocket teeth 28 engaging a drive chain 29, this chain receiving motion from a sprocket 30 secured to a transverse shaft 31. This shaft 31 is journaledon'the upper end portions of inclined beams 32 which are liXedly connected to the front end of the frame 3 and are extended downwardly and forwardly therefrom. A sprocket 33 is secured to shaft 31 Vand receives motion, through a chain 34, from a motor 35 mounted on one side of the frame 3 adjacent the back thereof. A water tank 36 is mounted on said frame adjacent theother side so as to counterbalance the motor.

I A longitudinal shaft 48 is journaled at each side of the machine and provided with a bevel gear 49 which meshes with another bevel gear 50 secured to a shaft 81. A fly wheel 51 may be secured to each of the shafts 48. Between the shafts 48 is arranged an upwardly extending platform 65 from the sides of which extend upstanding walls 66. A transverse shaft 68 is journaled in the upper end portions of the walls 66 and carries a.

roller 69 engaged by an endless conveyer apron 70. This apron is inclined downwardly and forwardly along the upper sur face of theplatform 65 and may be provided with transverse cleats 7 3 for engaging the corn and carrying it upwardly. Shaft 68 receives its motion through a gear 74 meshing with another gear 75 secured to the shaft 31.

Supported by the frame 3 back of the beams 32` are downwardly and rearwardly inclined side walls 80 in which is journaled a shaft 81 having a sprocket 82 which receives motion, through a chain 83, from an.

Y of the conveyer and an inclinedboard 88 is located under the conveyer for directing loose corn into the trough 21. Transverse beams 88 connect the side walls 8O near the upper and lower ends thereof and journaled in these beams are shafts 89 carrying husking rolls 90. The upper end portions Y of the shafts 89 have gears 91 which mesh with each other, it being understood that the shafts 89 are arranged in pairs and that the gears of each pair mesh so that the shafts of each pair will rotate in opposite directions. One shaft of each pair has a bevel gear 92 at its upper end, this gear meshingvwith another gear 93 secured to the shaft 31.

Shafts 94: extend across the space betweenY the side walls 80 and have cranks 95 which are journaled in the side walls 80. An arm 96 extends downwardly from one of these cranks 95 and is connected, by a pitman 97, to a crank arm 98 arranged lat one end of the shaft 31. The shafts 94: are secured to the 'end portions of a block 99 carrying brush bristles 100,- this block and its bristlesv being adapted to work up and down within the 'space between the walls 80 when the crank arms are swung back and forth by theV pitman 97 and the crank arm 98.

It will be apparent that when the motor is-in operation and driving the mechanism of the machine, the said machine will be propelled forward, motion being transmitted to the axle 1 andthe wheels 2 by chain 29, this chain receiving motion from sprocket 30 secured to shaft 31 which, as hereinbefore explained, is driven by the motor through chain 34. At the saine time motion is transinitted through chain 83 to shaft 81 and the gears 50 thus drive gears 49 and cause the shafts 48 to rotate.

The apron 70 is operated continuously through gears 7 5 and 74 and shaft 68 and ears, when deposited onthe apron will be `carried upwardly and drop onto an apron 101 along which theywill gravitate onto the upper ends of the husking rolls90. These rolls, as hereinbefore stated, are arranged in pairs, the rolls of each pair rotating in, opposite directions andsaid rolls receiving motion'V through the gears 93,l 92 and 91. A'sthe ears `pass downwardly along' the inclined husking rolls 90, the block 99 and bristles 100 are` moved downwardly and upwardly so as to press the ears Vagainst the husking rolls thus forcing the husks posi- Copies of ythis patentmay be obtained for ve cents each, by addressing vilashingtoli,l D.
