3 Claims. (01. 130-5) This invention relates to corn'husking rollers.

An object of this invention is to provide a husking roller having husk removing fingers which are so constructed and mounted'that they will remove the husks without removing the kernels of corn from the cob.

Another object of this invention is toprovide a husking roller with resilient husking fingers which project from the cylindrical wall of the'roller. In one form of this invention each finger isformed integral with an end of a, resilient bar which is fixedly secured to the inside of the roller. In a second form of this invention, the finger is formed with a spiral base which is slidable'through the wall of the roller, and a spring bearing against the inner side of the base constantly urges the finger outwardly.

A further object of this invention is to provide an improved mounting for one member of each pair of rollers, the mounting'inc'luding a swingable spring-pressed bearing at'each'end of one roller so as to thereby prevent crushing of the ears of corn and also to provide resilient gripping contact between the pairs of rollers to pull the loosened husks from the cobs.

With the above and other objects 'in view, my invention consists in the arrangement, combination and details of construction disclosed in the drawings and specification, and then more particularly pointed out in the appended claims.

'In the drawings,

Figure 1 is a detail side elevation 'of a series of corn husking rollers constructedaccording to an embodiment of this invention,"

Figure 2 is a fragmentary plan view of a pair of the rollers,

Figure 3 is a fragmentary sectional view taken on the line 3-3 of Figure 2, a

Figure 4 is a fragmentary transverse sectional view taken on'the line 4-4 of Figure 2,

Figure 5 is a fragmentary sectional View taken substantially on the line 55 of Figure 4'.

Figure 6 is a fragmentary side elevation of the yieldable mounting for one member of each'pa'ir of rollers.

Figure 7 is a fragmentary sectional view of a modified form of roller construction,

Figure 8 is a sectional view taken on the line 3-8 of Figure 7.

Referring to the drawings, and first to'Figures Ito 5 inclusive, the numeral hf! designatesgenerally a frame which is formed of opposite parallel'side members i l. The frame Iilhas 'journaled between the side members il thereof pairs of husking rollers i2 and I3. The rollers 13 are mounted in fixed bearings M which are secured to the side members ll whereas the rollers 1.2 are mounted in swinging bearings as will be here inafter described. The rollers 12 and I3 are -of like construction and the detailed descriptionofv one of these rollers will apply equally as well to the other roller.

The roller l2 includes a cylindrical body 5 which has secured to the opposite ends thereof head members I6. The head members 1,6 have disposed in the axial center thereof outwardly extending stub shafts I! having a plate l d/at their inner ends secured by fasteningmeans 19201' the like to the head it. The roller .l2.has;.the stub shaft ll at one end thereof jjournaled through a bearing sleeve -20 which is carried by, a vertically disposed supporting plate 2|.v The supporting plate 2| is pivotally secured to-a-base member 2-2 which is secured by fastening means 23 to the upper side of'a side member II.

The bearing member has an eye ziextendeing angularly and downwardly therefrom with: which one end of'a roller tensioning Springi'lSi'is adapted to engage. The opposite end of .the spring 25 is secured .toan eye 26 Ma turn buckle 21. The opposite end of the turn bucklez'l which has an eye 28 is secured b fastening means 29' to the outer side of the side member H. The turn Jouckle 21 extends downwardly from the roller 12 and in the direction of the roller l3 so that-the, tensioning of the spring 25 will cause the roller I 2 to be spring tensioned against the roller 13. The roller I 2 has extending therethrough, a plurality of husking fingers 30 which loosely extend through countersunk openings 3| formed-in the cylindrical body [5. The husking fingers 30 are disposed in staggered relation abouttheperiphery of the roller l2 and the free'end of each finger 30 is, slightly expanded and formed as an encircling stop means "to avoid any tendency of the finger end to catch in the openings 3i-gand formed integral "with the inner end'thereof isa resilient bar 32 or body section placed at 90? thereto and extended longitudinally .of-ythe drumv terminating in an eye 33 formedv integrally thereof.

A fastening bolt or screw 34 is extended through the body I5 from the outer side thereof. and then extended through the eye 33. A clamp ing nut 35 is threaded 011113116 inner end ofthe bolt and a Washer 36 may be interposed between each finger bar 32 or body section is relatively long, being proportioned to effect a gentle pressed finger action against the unhusked ears of corn just sufficient for penetration of the husk without injury to or the shelling of the corn kernels from the cob.

These fingers 30 are designed to separate the husks from the corn cob so that the spring tensioned rollers will grasp the free ends of the husk and pull the husk from the cob as the rollers rotate. The roller 12 has mounted on at least one stub shaft thereof, a sprocket 31 and the roller [3 has mounted on its associated stub shaft 8. sprocket 38. A roller operating chain 39 engages the

sprockets

31 and 38, being trained over the top of the sprocket 31 and beneath the sprocket 38. In this manner the two rollers forming a pair, will rotate in opposite direction. The chain 38 is trained over a driving sprocket 48 carried by a driving shaft 4| which is connected to a suitable power means and preferably the upper run 42 of the chain 39 is trained over an idler sprocket 43.

According to the preferred form of the invention, the stationary rollers l3 rotate in a counterclockwise direction while the so-called floating rollers l2 rotate in a clockwise direction. The removed husks will inevitably drop downwardly through the spaces shown between the adjacent pairs or rollers while at the same time these spaces are not sufficiently large to permit the ears to drop.

As will be appreciated, the rotation of the rollers will automatically carry the ears forwardly from the driving end to the driven end, or in fact, such rotating rollers may automatically result in the shucked ears being moved laterally of the apparatus and oil the same. If desired, to facilitate this more or less gravitational sliding movement of the corn ears away from the rollers, the latter may be inclined slightly to one side or the other.

Referring now to Figures 7 and 8, there is disclosed a modified form of roller construction and husking finger. The body 44 of the roller has extending inwardly therefrom a cylindrical member 45 which is formed with a closed inner end 46. The cylindrical member 45 is internally threaded as at 41 and a nut 48 engages the threads 41. A movable or spring finger 48 is slidable through the bore 50 of the nut 48 and is formed at its inner end with a spiral base The base 5! bears against the inner end of the nut 48 and the diameter of the base 5| is such as to provide for the free inward movement of the finger 49 and the base 5|. A finger tensioning spring 52 is interposed between the inner side of the base 5| and the bottom wall 46 and a washer 53 is interposed between the outer end of the spring 52 and the inner side of the base 5|.

With a husking roller construction as hereinbefore described, the husk loosening finger or the finger 49 will loosen the husks from the corn cob without loosening the kernels of corn and the loosened husks will be grasped between the contacting portion of the two rollers l2 and I3 which will thereupon pull the loosened husk from the corn cob or ear. The tension of the

fingers

30 and 48, is such as to provide the necessary loosening action of the husk without loosening or removing the kernels of corn from the ear. In any of the resilient fingers become damaged they can be readily replaced by the insertion of a new finger as will be readily apparent. The insertion of the new finger is made for the construction shown in Figures 1 to 5 by removing one of the end heads and then inserting the finger into the interior of the roller and applying the head bolt to the eye of the finger construction. The spring pressed or resilient finger shown in Figure 7 can be readily replaced by unthreading the tensioning nut 48 and inserting a new finger for the damaged one.

I do not mean to confine myself to the exact details of construction herein disclosed, but claim all variations falling within the purview of the appended claims.
