My invention has relationto in'iprovemeiiti: in corn huskingmachines', and it-consists in the novel features of construction Ymore fully set forth inthe specification and pointed out inthe claims.` l

The object of the invention machine that will `break the ear trom the lstalk yand remove the shucks therefrom. as the ear passes through the machine. A further object is to provide a cornhus'king machine that is simple and composed 'ot'comparatively few parts so asto not readily get out of order. q Further and other advantages will be better apparent'from` a detailed description of the invention'in connectionV with theaccompanying drawings, in which- Figure 1 i's-al top plan et, my improved machinewith parts broken away; Fig. 2 is a' l side'elevation' thereo'jFigSis a vertical lsectional detailit'aken on the line of Fig. 1; Fig. 4 is a detail view ofthe upper end of the huskingrollers-showing how they i are ymounted and driven; Figs. 5,6 and 7 aretop plandiagrams showing' three successive positions of the ear et corn in: the ma'- chine; Fig. 8l is 'a Vside kelevation with vthe parts in a position corresponding withthat in Fig. 5,'betore the ear has been engaged' by the crank; and Fig. v9 f is a similar jview showing the crank moved to raise the ear'so that it will be grippedbetween breaking roller and abutment block.` y y y u Y Referring vto the drawings, 1 rep-resents a Sledge on which is mounted asteelframe'- work-2 provided with ay table, or platform 3 composed of sections a, l? between which'is a slot 4 having a flaring mouth4 v5;.The sec y ranged with 'their upper ends-.below andv on tion (t is fixed on the framework` 2, but the section is hinged-thereto so that it may be raised in order to permit access to the machinery below the table.

A counter-shaft 6 vs mounted in bearings 7, 7 secured to opposite angle braces 8i, 8 of the framework, said counter-shaft having a pulley 9 on one end adaptedy to be connected by a Lbelt 10 to drive pulley 11 of an engine 12 rigidly secured to the Sledge 11.

A cylindrical abutment block 13 is ixed to the underside of section. a of' the table 3, adjacent to the sloty 4, said block 'being traversed by a vertically disposed shaft 14 mounted in bearings 15 and 16 mounted respectively in t-he table and Sledge. A'crank. 17 is fixed on the shaft 14 immediately be vlow the block 18a-nd a spindle 18 projects upwardly from the free end of said Crank,

is to provide a`r said vspindle having a roller 19 loos-ely mounted for rotation lupon it. 'A worriiw'heel 2O is fixed on rthe shaft'14v just below the crank 17, and worm 21 ifs fixed vvon shafty 6 `shaitt 6 by means" of engine 12;" A'toothed dog 22 ispivotally Secured on theundersideof section Zn'of table 3 just'about opposite 4the block 13, said -dog being urged to in a' position to mesh Vwith 'wheel 20, where'- v n Y upon th'ecra'nk 17 willberevolved around.` 4the block 1301i imparting motion tolv the lject slightly beyond the adjacent edge of the Y- slot 4 lby a? string 23,"the movement' of the y dog toward'the slot being limited by a-Ystop pin 24. l

' W ith the 'crank 17 revolving (about-66 i?. M.) as above describedjifastalkjofcorn is drawn backward Over-the table 3 so that "one of the ears `:falls into',v the zslotu4`,` 'said eary will hang-idown'in the path ofthe ycrank 17 (see Figs. ,"5 'and 8) `which will vstrike the ear, tilting it upward (Figsl 6 and so that thev revolving roller19 will warpithe ear around theblock 13" (Fig.4 7) until itbrea-ks from the stalk.'l `|The stalk-is heldin place during the above operation' by the operatorl and is prevented from yielding, under 'the pull exerted Aby the crank 17, the 'dog `22 wliichfgrips the shuck near the point where the ear is attached to the stalk. VVlheco-op'er.-

inclined downwardly to a chutej42.

26 have. complementary.depressions 28jfor receiving said spines. At their upper ends the rollers 25, 216 are providedwith spindlesv The rollersr-of each pair have spines 27 pro*` jecting from their surfaces, and the rollers 1GO, i

29, 30 respectively mounted for rotation in bearings 31, 32 iXed on a supporting angle iron 33, and :at their lower ends'the rollers have spindles 84, 35 mounted. in .bearing brackets 36, '37 respectively. A pairrof pinp i i ions 38, 39 are mounted onspindles 29, 30

of each pair of rollers 25, 26 respectively,

and bevel pinions 40, 40 are mounted on the' upper ends of spindles29, 30, the pinions 40, 40 meshing with bevel gears 41, 41 fixed on the counter-shaft 6, so that when said shaft is rotated (as heretofore described), the rollers of one pair and rollers 26 of the other pair will be rotated. As the rollers 25, 26 of each pair are ,connectedv by the pinions 38, 39 said rollers 25, 26 will be rotated toward each other, the spines 27 Vof rollers 25. yentering the depressions 28 of rollers 26 as said rollers rotate.

. If an earof corn is broken from the stalk without being Vshorn of its shucks, it will fall through the hopper H and land upon one or the other of the pairs of rollers just vdescribed, adjust-ing itself p longitudinally of f use in Corn shncking machines, and I make no claim to said shucking rollers except in combination with'the mechanism that I employ for breaking the corn from thel stalk. In order that the sl-edge 1 may be easily moved in the course of the cornl h usking operation, I provide a drinn 44 loosely mounted on the vshaft 14, said vroller being 'capable ofl connection with the shaftby means of the clutch members 45, 461of a f clutch, the member`45 being feathered on the shaft 14, and operated into andout of engagement with the member 46' fixed to drum 44 by means of a shift lever 47. I A rope 48 has one end secured to the drum while the other end may be connected to any fixed support, such as a tree, whereupon,

V when' the drum 44 is rotated, the rope 48 will be wound thereon and they sledge dragged to a new location.

Having described my invention I claim: 1. A corn-husking 'machine comprising a platform, said platform having a slot, provices.

said block, and a roller vertically disposed on the free end ,of the crank-arm, means for revolving said roller about'the block, theV said slot in the platform being` adapted to receive an ear of corn as .the stalk is disposed on the platform, means for holding the stalk in place when thecrank is rotated to lift the ear of'corn to a position so that the roller will warp said ear over the abutment, thereby breaking the ear from the stalk.

2. In a corn husking machine, the combination of a'fcornbreaking and a husking device, the breaking device comprising relatively fixed and movable members,said morvable member being adapted for rotation about the fixed member, thehusking device comprising oppositelyrotating rollers Yhaving formations .adapted to tear the shucks from tlie corn, mea-ns yfor guiding the def tached corn to the` husking` rollers, and means inolndinga source of motive power for actuatingthe breaking and husking de- 3. In 'a corn husking machine, av work yplatform having a slot adapted to receive the depending earof corny when the stalk is placed on said platform, an abutment block beneath said platform and adjacent to said' slot, a shaft disposed on the vertical axis of i said block, a crank fixed on vsaid shaft immediately below said block, a roller. mounted onv thev end of saidcrank and having its vertical aXis parallel to that of the block, said roller being revolved about the block and operating to warp the'ear of corn over the block to break it from the stalk on impart- I ing motion to theshaft, means for holdingV the' stalk while the ear is beingk detached therefrom, and ymeans for 'actuating the shaft.

yIn testimonyy whereof I hereunto my signature.
