CORN-HUSKING ROLLS.

Specification of Letters Patent.

vPatented. Dec. '7, 1920.

Application sied January 14, isis. serial No. 211,794.

useful Improvements in Corn-Husking Rolls; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

This invention relates to Vcorn husking machines, and has particular reference tothe construction of the husking rolls.

The object of the invention is to provide an improved form of liusking mechanism by a more etiicient arrangement of the liusking teeth or fingers with relation to the rolls, together with a practical mounting therefor. By means of my improved construction, the teeth and their mountings' may be manufactured at a minimum expense, and the teeth so insertedtherein or secured thereto that they may be sharpened without removing the mountings from the rolls,` Provision is also made, in the assemblage of the rolls to` prevent the breaking of the teeth when the driving gears of the rolls accidentally become disarranged so as to cause the teeth to rotate in untimed relation.

With the above objects in view, and such others relating to the details of construction, as may hereinafter appear, my invention will now be fullyv set forth and described,

reference being `had to the accompanying drawings. Y

ln the drawings VFigure l is a fragmentaryplan view of a pair of rolls, having the invention mounted thereon, p

Fig. 2 is a fragmentary perspective view of one of the rolls, l

Fig. 3 is an enlarged perspective view of one of the mountings withV its associated teeth,V Y I' Y Fig. 4 is a transverse section through the rolls, and 'f Fig. is an enlarged 'section' through one of the tooth,V mountings.

Referring more particularly to the drawings, l and 2 represent the rolls of a corn husking machine which are mounted in contiguous parallel relation so as to close the bottom of an elongated hopper. The rolls i and2 Vmay be constructed of wood, metal or a combination of rthese Amaterials in accordance with any particular-or desired method. At regular intervals, the rolls l and 2 have cut'into their peripheral surfaces the wide channels 4 and the narrow channels or grooves 5, the wide channel 4 and the groove 5 coming into closely spaced relation for the purpose whichy will hereinafter appear, and, with relation to the juxtaposed rolls, a narrow groove of one roll appearing opposite the wide channel 4 of the opposite roll.

. The channels 4 provide seatsfor annular bands, each made in a plurality of sections 6, and preferably in two semi-circular sections as shown, meeting end to end andheld within each channel removably by fastening' means such as the screws 7. The band as so constituted is as thick and as wide as the channel so that when in place its periphery complements that of the roll and, as

seen in-Fig. l, each channel is wider than the opposite groove'so that the band within it extends beyond both side walls of such groove. The bandsections 6, in the form illustrated, are provided with Asockets hav-V ing spiral bottoms growing gradually deeper in the direction of rotation of the rolls to their rear endsv 10 which are abrupt and radial. Each tooth 8 has a curved bottom resting on the bottom o f the socket, a broad sharpcutting edge l2 undercut at its front end as at 13, and a receding back 14. The front end of the tooth is wholly beyond the periphery of the roll as seen in Fig. 5, its rear end is wholly within the socket at the rear -end 10 of the latter, and its body between these ends is both curved and tapered from front to rear. The angles 12 between the front ends and backs of the teeth are sharpened so as to provide broad cutting edges which will take hold of the husks of the corn deposited in the hopper, and tear them from the ears. When the peripheries of the iolls l and 2 roll one against the other, the outstanding parts of the teeth on one roll operate in the groove 5 of the opposing roll; and in gearing the rolls toJ scribed, the teeth are so arranged that they will husk the corn thoroughly with a smaller percentage of shelling of thekernels than isV mounted upon semiscircular Vbands which may belsupplied ffor the renewal of the teeth upon` used rolls, ,and lwhile the teeth are shown in the present instance as inserted into'th'e ibands, they may be otherwise se cured thereto or they may be :formed as int-egaall elements.- ofthe bands.

`It is'well known that heretofore husking rolls fhave fbeen constructed with pointed teeth on one roll'received in grooves in anotherroll,A andv in theroperation of the husking machine 4the teeth, by reason oftheir pointed lforination, penetrate the grains of cornnandicause'the grains to be mutilated andpulled fromrthe cob. These teeth when entering the grooves do not completely close? the :same Vonv opposite sides of the teeth, andthus the space becomes crowded with the eohs sand husks, and the resultant pulling action of sa-iclhusks will cause the grains to be shelled, as Welllas clogging the husks in thefgro'oves `ofthe vrolls in the machine when operated.

In the present invention, the teeth are formed with `loroad cutting edges which eompletelycllose the grooves ente-red thereby, thusholding the ears out of said grooves and avoiding clogging by the-husks and at thek same time'preventing the teeth cutting through said v`husks and shelling the grain from said cob. The rolls hold back the ears,

chine.

It `will therefore be obvious that I have provided a. very simple and efiicient organization of parts for the husking rolls of corn husking machines.

lhat claim as my invention is z* l. Corn husking mechanism comprising two rolls rotated oppositely and in contact and each having relatively narrow annular grooves andrelatively wide annular channels respectively opposite like channels and grooves in fthe other roll, a band in each channel made upV of a plurality of sections of a thickness and Vwidth to fill the channel and to extend` beyond the edges of the groove in the opposite roll, means for securing said sections removably in place end to end, and teeth on each section extending beyond its periphery and of a width to fill said groove.

2. Corn husking mechanism comprising two rolls rotated oppositely and in Contact and each having annular channels opposite grooves in the other7 semi-circular band sections removably secured in and filling each channel and having sockets whose bottoms grow deeper from front to rear in the direction of rotation and whose rear ends are abrupt and radial, and a tooth fitted in each socket with its front end extending V)eyond the periphery of the roll and undercut, its cutting edge of the same width as the groove with which it coacts, and its back receding to its rear end where it is flush withthe periphery of the roll. Y

In testimony whereof I aflix my signature in the presence of two'witnesses.
