rlhe roll L is journaled in fixed bearings 52 and 53 carried by oneof the side frame i 5 members 4, while the roll 50 is journaled in yielding bearings 54 and 55 carried by the other side frame member 4. One of the bearings which are substantially identical in structure, is shown in Figure 6,'and each 1 0 comprises a bearing member having a lateral arm 56 slidable in a bracket 59 fixed on one of the side frame members 4, a compression coil spring 60 surrounding the arm'56 and interposed between the bearing and the bracket and-thus urging the said roll 50 yielding toward' roll 51. l

The rolls"50 and 51 at their forward ends are' conical 'in form as at 61, and-provided each with a spiral flange 62 for the purpose 120 of feeding the corn stalks from the carrying chains 15 to tions 64 ofthe rolls 50- and- 51, and which snapping portions remove the ears of corn from the stalk and deliver them to the husking portions 65 and 66, said husking portions constituting the ma'or portion of the rolls and 51. The huskin is p vided with a plurality-of longitudinal series of alternate-pins 68 and apertures 69 y"$0` arranged around each roll, the pins of one y roll being adapted to register with the aperroll and vice-versa as the rolls rotate.

Each of the rolls is Il gear which mesh to drive the lrolls in opposite directions, one of the rolls as 51 being provided with a bevel gear 72 in mesh' vflitlita bevel gear 74 fixed on the main drive 4o As the ears of corn, indicated by the' letter Xin Figure'10 are snapped fromthe stalk.

' by the snapping portions '64 of the rolls, the arejcaught by lingers 78 mounted o n an en ess carrier sprocket chain` 79 which 45 travels' longitudinally of the rolls over sprocket wheels 80 and 81, respectively, the

--l- {former being mountedto rotate on a vertical i' axis, on a stub-shaft 82 journaled in a bearing86 formedfon'the outer of the bearings 5o 11, the stub-shaft carrying a bevel gear 89 meshing with a similar gear 90 keyed on the main power shaft'8. The latter or forward sprocket wheel 81 is also mounted-to rotate on a vertical axis, being "ournaled on a vertical shaft 91 on the side ame member 4. The lingers 78 are arranged on the chain equal distances apart so that the space betweenfan two fingers is approximately the length'o an ear of corn.'

The rear portion of the inner stretch of e carrier chain is guided over an idle sprocket 92, while the forward portion is guided over an idle sprocket wheel 93 journaled on a horizontally swinging arm95, M the inner end of which is pivoted on a the snapping corrugated porg portion of each roll'- provided witha spur vertical arm96 ixed on the side frame'mem-vv ber 4,. the arm being urged inwardly by a coiled compression spring 98. The purpose of this construction issto cushion the carrier chain so that, should the ears wedge, the

spring 98.will permit the chain to ield and the fingers on the chain to pull ack .and

slide varound'so that breakage is'overcome.A

Extending longitudinally of and arranged. above the roll 51 is a board 99 securedto the outer of the side frame members 4, saidy board having a number of L-shaped brackets V100. to the free ends of which is secured a guide bar 101, more clearly-shown .in Figure 1.0, said bar 101 serving as a guide for the chain 7 9, the fingers 78 on which are upward extensions 102 which engage the inner face of said bar, while the chain in its travel rides on.' the upper face of,l the board 99. Opposed to but cooperating with the board 99 is a longitudinal inclined board 104 arranged over Vthe roll '50 and covering, with' the board 99, all that portion of -the rolls except that which is to operate upon the ears of corn in removing the hu'sks. Owingto the fact that the fingers 78 are supported ypon'the board 99 by the brackets 100 and the guidel bar 101, the fingers 78 are of suf- .Referring now to the modified form of my apparatus as shown in Figure 11, which discloses a construction adaptable to the present machine, and falling within the scope of my inventiomami wherein the principal 'other figures are employed, husking rolls 116 having the. same `arrangement of pins -portions of the apparatus as covered by the 118 as in the other figures, are mounted on rotary shafts 119 j'ournaled at their ends in bearings -120 and 121 and intergeared through the spur gearing 122, carrier chains 124 being also employed as and for the same purpose as the chain 79 in the other figures of t e drawing. 7 (Y The construction differs' in the present modification from the structur first described in the arrangement of the snapping rollers 126, these shafts128'arranged in parallel relation wit being carried on rotary Athe husking rollers and being intergeared by gears 129 fast on the shafts 128. The shafts are driven through the medium y`of cooperating bevel gears 130 and 132 mounted resp`ectively `on one of the snapping rollershafts' 128 and the power drive shaft 8. The forward ends of the snapping rollers are, as

in the case of the Ffirst' described construc-V tion, provided .with conicalgathering por'-l tions 138 provided) with spiral flangesli. Of course, in the present construction, it is necessaryA to transfer by some means, lthe 'being snapped to the husking further action. It is, of course, vfurther understood-that one of the husking rollers as welljas the carrier chain be yield'- arrangement.

From-,the foregoing description of the construction of my improved apparatus, it

will be seen that. I have provided a. simple, inexpensive and eicient means for carrying out the objects of theV invention, and while form, proportion,

vI .have particularly described the elements ted to perform the functions set forth, it is obvious that various changes in and in the minor details of construction may be resorted to, without I claim as -newis departing fromthe spirit or sacrificing any ofthe principles of the invention.

Having thus described my invention, wl'iat 1. A corn harvester comprisingga frame, rolls located above the rolls 'and disposed longiournaled thereon, a panel board tudinally thereof, brackets mounted upon the panel boards, a guide bar carried by the' bracket and having its lower edge spaced '.abc've the upper surface of the panel board, the guide bar being disposed in a plane at a right angle to .the lane of the panel board, a chain mounted fier ."movement upon the upper surface of the panel board, fingers carried at the side-of the chain and resting directly upon the upper surface of thepanel board, said fingers completely brid ing the space between the upper surface of t e panel board and the guide `bar and said fingers passing through the space between the panel board and the guide bar.

2. A corn harvester comprising a frame, rolls journaled thereon, a "panel board located above the'rolls and disposed longitudinally thereof, brackets mounted upon the anel board, a guide bar carried by the brac et and having its lower edge spaced above the upper surface of the panel board, the guide bar being disposed in a plane at a )bright -angleto the plane of the panel board,

a chain resting directly upon the upper surface ofthe panel board, fingers carried at the side of the chain and resting directly `upon the upper surface of the panel board and extending through the space between the panel board and the guide bar, said fingers having angularlydisposed lugs which engage the inner surface of the ide bar and said fingers completely bridging the space between the panel board and the guide bar.

In testimony whereof I affix my signature. WILLIAM H. SANDIFUR.
