(C1; 130—'-5) 1 V This invention relates to husking rolls. ~More speci?cally, it relates to a husking roll construc ‘they will be individually described. A roll sup porting a_--drivev shaft l4 carried at one end'by the bearing bracket l3' provides-means for mounting through which the stalks of corn are fed for snap a tubularlhusking 'roll- I5 which is provided with a thick rubber covering ‘I6. ‘Said rubber cover “ing provides means for gripping the husks on the ears of ‘corn and starting themplthroughi between pine the ears therefrom. It hasalso been com therollers. ' The shaft ‘Mextends through a bear tion for corn pickers. Conventional corn pickers utilize a pair of snapping rolls driven in opposite directions mon practice to carry the ears along the same set ing‘bracket !5’ which is secured to the vanglejbar of rolls and provide'husking means beyond the ll of the frame.

Other objects relating to the speci?c construc the lower end. A snapping r011 structure 25 is tion will be apparent from the detailed descrip mounted on the shaft 20 adjacent the bearing bracket 22. Said structure is provided with a re tion to follow. In the drawing: duced end portion 26 which provides means for 35 Figure 1 is a plan view showing a set of com attaching one end of a coil spring 21. The other bined snapping and husking rolls embodying the end of said spring is secured to a member 21’ invention and such portions of a frame structure which is carried within and rigidly secured to a as are necessary to show the location of rolls in tubular husking roll 29. Said husking roll is nor mally mounted concentric with the shaft 20, be a machine; Figure 2 is a section taken through the centers 40 ing resiliently retained in concentric position by of the husking-roll driving shafts; means of the spring 21 and a similar spring 28, Figure 3 is a section taken on the line 3-—3 of as shown by the broken-away section of Figure 1, at the other end of the roll. There is sufficient Figure 2. As snapping and husking rolls are very well space, however, between the inside of the spring known in the art, and their location in a corn and the shaft 26 and the outside of the spring picker is well understood, only a portion of a and the inside of the tubular roll 29 to permit a picker frame has been illustrated in the drawing. substantial deflection of the roll 29 out of con The portion of the frame illustrated consists of centric relationship with respect to the shaft 25. longitudinally extending angle bars l0 and H. In Figure 1 it will be noted that the bracket 22 These bars will be mounted at an angle in the ' is in a position of adjustment at the extreme end conventional picker. A pair of bearing brackets i2 and I3 are bolted to the angle bars l0 and H, respectively, to provide means for supporting the snapping and husking roll structure. As the two rolls are of different construction, of the slot 23 whereby the husking-roll structures I1 and 25 are brought into contact with one another. In this position of adjustment, the roll 29 is moved against the rubber-covered roll 15 2,413,279 with sufficient force to de?ect the rubber cover ing 16 to a certain degree and at the same time to push the roll 25 into an eccentric position What is claimed is: 1. A husking roll construction comprising a pair of parallel driven shafts, a husking roll carried by with respect to the shaft 20. This de?ection is illustrated in Figure 2. In otherpositions of ad justment of the bracket 22 there will not be as much pressure against the roll 29 and there may be no de?ection out of the concentric position when no material is passing between the rolls. In generally cylindrical coiled springs concentrically a portion of a stalk, passes between the husking rolls. The rubber covering is de?ected a sub 2. A husking roll construction comprising a pair of spaced parallel shafts, a roll securing member one of said shafts, a tubular husking roll posi tioned around the other shaft spaced therefrom, positioned around the shaft and between the shaft and the tubular roll, and means for securing each Figure 3 an illustration has been given as to what “ spring to the roll at one of its ends and to the shaft at its other end, happens when a large piece of material, such as at the ends of each shaft, a tubular husking roll rigidly secured to the members on one shaft, a stantial amount and the roll 21 is moved into an eccentric position until its center is moved from C to C’. This is the extreme position as the roll 29 then abuts the coils of the spring, blocking any further movement. As soon as the material or object which caused the sep aration- passes through the rolls, the roll 29 re second tubular husking roll positioned around the second shaft, said second roll being provided with spring-securing members spaced axially from the ends thereof, the roll securing members on said shaft being provided with extensions in the annular space between the roll and the shaft, and a generally cylindrical coiled spring having a plu rality of coils of substantially the same diameter at each end of said husking roll surrounding the turns to its abutting position against the rubber covering IS, The provision of springs at both ends of the rolls gives a degree of ?exibility which is Very signi?cant as a large piece of material may be passing through the rolls at one end while \ at the other end the rolls are sui?ciently close shaft, each spring being secured to the spring securing member at that end and to the roll securing member at the corresponding end. 3. A husking roll construction comprising a pair of spaced parallel shafts, said shafts being pro vided with means for driving them in opposite angular direction, roll-securing members at the ends of each shaft, a tubular husking roll rigidly together to grip and remove paperlike husks. This is particularly true due to the de?ection of the rubber covering by pressure of the resiliently mounted roll 29. The construction as above described also per mits the use of constant mesh gears for the driv ing shafts which are not moved apart when there secured to the members on one shaft, said roll is relative movement between the rolls. The ad justment of bracket 22 angles the gears I8 , slightly with respect to each other, but these gears are of the loose-?tting, agricultural type which operate satisfactorily with small angular changes in their axes. Another outstanding advantage of vi being covered with rubber, a second tubular husk ing roll positioned around the second shaft, said roll being provided with spring-securing members spaced from the ends thereof, the roll-securing members on said shaft being provided with ex tensions in the annular space between the roll and the shaft, and a generally cylindrical coiled the construction of this invention is that the 4 spring having a plurality of coils of substantially snapping rolls are not moved apart by movement the same diameter at each end of said husking of the husking rolls carried on the same shafts. roll surrounding the shaft, each spring being se This permits a simpli?ed combined snapping cured to the spring-securing member at that end roll and husking-roll construction with the re and to the roll-securing member at the corre quired spacing of the snapping rolls and the yield sponding end.
