CORN HUSKING AND CUTTING MACHINE.

SPECIFICATION forming part of Letters Patent No. 639,615, dated December 19, 1899.

Application filed March 29, 1899.

T0 aZZ whom it may concei /a Be it known that I, AUeUsr ROSENTHAL, of Milwaukee, in the county of Milwaukee and State of Wisconsin, have invented a new and useful Improvement in Corn Husking and Cutting Machines, of which the following is a description, reference being had to the accompanying drawings, which are a part of this specification.

My invention has relation to improvements in corn husking and cutting machines.

The object of the invention is the provision of rollers of such construction that the cutting mechanism is carried directly thereby, in connection with a frame for supporting; the rollers, said frame being so constructed and arranged as to permit the cornstalks to be fed longitudinally and to arrange themselves longitudinally on the rollers.

With the above primary object and other incidental objects in view the invention con sistsof the devices and parts or their equivalents, as hereinafter more fully set forth.

In the accompanying drawings, Figure 1 is a side elevation of a machine embodying my invention. Fig. 2 is a transverse section of Fig. 1 on a plane through the cutting portions of the rollers. Fig. 3 is a detail plan view of the rollers. Fig. 4 is a cross-section through the portions of the rollers where the separation and cutting is effected, the section being taken on a plane between two of the cuttingknives; and Fig. 5 is a View of a fragment of the shaft or axis of one of the rollers with the clam ping-collars which surround the shaft in section.

Referring to the drawings, the letter A indicates the base of the frame, B B the side boards, and C C the inclined side pieces of the hopper. These side pieces extend longitudinally of the frame and their lower edges pass below and on the inner sides of the upper edges of the side boards B B, said lower edges converging towards the roller hereinafter specifically described. Mounted in suitable bearings in the frame is a shaft D, the inner end of said shaft extending into a fan-casing F and having mounted on said inner end a fan F. On the outer end of the shaft D is a pulley E, around which a belt (not shown) may be passed for the purpose of imparting Serial No. 710,886. (No model.)

rotation to the shaft D. The framework is on a gradual downward incline from the front end toward the rear, and the side boards B B have two oppositely-inclined bottom pieces B E the latter inclining toward the former and adapted to deposit material thereon, the said inclined bottom B finally leading to an opening in the side of the fan-casing F.

The numerals 4 4 indicate shafts or axes for the rollers. These shafts or axes are shown as provided with reduced ends or journals which are mounted in suitable yielding bearings in the frame of the machine.

One of the end journals of the shaft 4 is shown as having mounted thereon a drivingpulley 5. The journals of the opposite ends of the shafts are provided with intermeshing gears 6 6. By the arrangement described the shaft 4 and its roller are rotated in one direction by power applied to the band-pulley 5, and the shaft 4 and its roller are rotated in the opposite direction by the intermeshing gears 6, with the result that the two rollers are rotated toward each other. The rollers are mounted in the framework of the machine so that the ends thereof where the pulley 5 is located constitute the forward ends. There is a gradual and equal declination of both rollers from these forward ends rearwardly. The solid portions of the rollers, on which the husking is accomplished, are indicated by the numerals 7 7. The remaining portions of the rollers are preferably made up of collars surrounding the shafts, the collars surroundin g the shaft 4 being indicated by the numeral 8 and the collars surrounding the shaft 4 by the numeral 8. These collars are held in place by means of intersecting pins 9. The solid or husking portion 7 of one of the rollersis provided with projecting husking-pins 10 and the solid husking portion 7 of the other roller with registering recesses 11 to receive said pins as the rollers revolve toward each other.

Clamped between the collars 8 of the shaft 4 are annular cutting-knives 12, which are arranged in series throughout the length of the separating and cutting portion of the roller of said shaft 4. The collars 8, surrounding shaft 41, are spaced apartaslight distance to form grooves 13 to receive therein the cutting edges of the knives, one side of each cuttingknife bearing against or in close proximity to one of the side bordering walls of a groove 13.

The several collars S are shown as provided with projecting conical nippers 14, there being preferably two of said nippers on each collar, arranged at diametrically opposite points thereof. Each of the collars 8 is provided with depressions or recesses 15, two of said depressions or recesses being also preferably provided for each collar and arranged at diametrically opposite points thereof.

In the operation of my invention the cornstalks are fed horizontally and longitudinally between the side boards 0 of the trough and thence pass to and arrange themselves longitudinally on the rollers, with the butt-ends of the stalks at the forward ends of said rollers, the stalks settling in the angles of the two rollers. As the rollers revolve toward each other the knives act on the stalks and out said stalks into fi e pieces or shreds. By reason of the fact th. Ithe rollers are mounted in yielding bearings the cut portions or shreds of the stalks are free to pass between the rollers and to fall on the inclined bottom pieces B B of the side boards B and thence slide down said bottom pieces and are finally conducted by the bottom piece B into the fancasing, where they are acted upon by the fan within said casin g and forced thereby through a conduit leading from the casing to the place of deposit. The knives by reason of their contact with the side walls of the grooves 13 efiect a shearing cut and are thereby rendered capable of effectually cutting the stalks in fine pieces. At certain periods of the rotation of the rollers the conical nippers are brought into register with the depressions or recesses 15, and the portions of the stalks from which the ears extend are thereby necessarily pulled in between the point or edge of the nippers and the wall of the depressions or recesses 15, and are thereby compelled to make a very short turn, the sharpened edges or points of the nippers at the same time pinching the stalks from the ears. The cars of corn so severed are too large to work down into the angle between the two rollers, so as to be affected by the shear cut of the cuttingknives, and hence the ears slide down the inclined rollers onto the husking portions of said rollers, where they are acted upon by the husking-pins and stripped of their husks.

So far as I am aware rollers have not heretofore been provided for a corn husking and cutting machine in which the separating of the stalks from the ears and the cutting of the stalks and the husking of the ears, if desired, is accomplished as in my invention. This form of rollers presents a decided advantage, inasmuch as the necessity of separate shredding orcutting mechanism arranged beneath the rollers or elsewhere is entirely avoided and simplicity and cheapness of construction in this class of machines thereby greatly promoted. By my improved construction also much less power is required than in machines in which separate cutting mechanism is employed, inasmuch as in such class of machines separate driving mechanism for the cutting apparatus is necessary. IVith my ar rangement but little power is required for causing the cutting-knives to operate, owing to the pressure between the two rollers, and said rollers therefore are not required to be speeded to agreat extent. In machines, however, in which separate cutting mechanism is employed a very high rate of speed for such cutting mechanism is necessary.

While in the preceding description of my invention I have described certain details of construction yet I do not wish to be understood as limiting myself thereto. For instance, it is not absolutely essential to my invention that the cuttingknives should be held between a series of collars and that a series of spaced collars should be provided on the other roller to form grooves to receiye the cutting-knives. The cutting-knives can be secured in any desirable manner, and the grooves on the other roller, if preferred, may be cut around or otherwise formed in said roller without departing from the spirit and scope of my invention.
