This invention relates to an improvement in continuous rotary centrifugal shear adapted particularly for converting sugar cane or other sugar producingr material into a fibrous mass which will readily pass through juice extracting rolls, and which is designed to be used in connection Withother mechanism for extractingr the nice from the cane.

The primary` object ot' the present invention is toiinprove the construction and mode of operation oit' devices for disintegrating sugar cane stalks and the like, and to produce an improved and highly ellicicnt machine by which such material may be disintegrated so as to rediure the saine to a liln'ous mass.

lith this and other objects in view the invention consists in the parts and combina.- tion ot' parts as will be more fully described ind pointed out in the claims.

lu the acconij-anying drawings, Figure l is a vien' in vertical. cross section of the apparatus; Figure il is a view .in plan of the is a view in plan of the top, the stationary disk being removed.

ln using the shredder or disintegrator the cane is cut into short lengths, about six inches more or less and these cut sections are then fed to the disintegrator which is located in the mill.

The canen'epared in the manner above described is red into an opening or openings (S in the top member or plate T of the rotary shear, which plate is stationary and held in place by the supporting member 48. The feed openinpr or openings are located near the center ol plate 7 which is circular in form and slightly conical. It is provided centrally with an opening closed by cap 9 which covers the upper cud of shaft 10. This plate T is provided on its under side with a series oi straightgrooves which radiate from the center o1 the member, and each -groove carries a shear blade or knife 11 which latter is beveled at its side edges and wedge shaped longitudinally the thicker ends o't the knives being adjacent the center ol plate as shown in Figure 1. The knives may be beveled at one or both side edges, but they may, it desired, be beveled on one 1927. Serial No. 34,878, led .Tune 4, 1925. Application for Serial No. 285,649.

side only so as to form cutting edges which co-act with the knives 12 located Within grooves 13 formed in the lower plate 14. This lower plate is circular in form, of less diameter than the upper plate and is rigidly secured centrally to the upper end of shaft 10.- This lower plate is flat so that when combined with the upper plate a gradually decreasing space is formed between the two plates, the space in the outer edge or periphery being comparatively smaller and constitutingr the outlet for the sheared or fibrous material. If desired, the lower or revolving plate may also be made slightly conical. The space between the two plates adjacent to the center, is considerably greater than the width of sugar cane stalk so as to permit the latter to be readily fed into this space and the centrifugal force set up by the revolution of the lower plate causes the material aslit is sheared to flow outwardly toward the outer edge of lower revolving plate.

The knives 12 in the lower plate may also be beveled and are curved or scimitar shaped longitudinally and fit within similarly shaped recesses formed in the lower plate. The shears 12 of the lower plate are deeper or thicker at their inner ends so that the knives project at their inner ends a, greater distance from the lower plate than they do at their outer edges. When the two plates with the knives are assembled the adjacent faces oi the knives are parallel and nearly in Contact.

Secured to the top or fixed plate or disk 7 is the circular trough shaped shield 17 which latter is secured to the underside of the upper disk 7 as shown in Figure 1, and projects downwardly, inwardly and upwardly and terminates well within the periphery of the lower disk 14, and close to the latter. This trough or shield 17 is as before Stated circular in shape, and is so located that the shredded fibrous material which is ejected at the periphery of the rotary disk is caught up by said shield or trough, and is carried around therein by the fan blades 18 which latter are rigidly secured to the underside of the rotary disk or plate 14, and operate by suction or air blast and by direct contact to carry the shredded material around and discharge the same tlnough the spout 19, from which it is carried by a conveyor or otherwise to the juice extracting apparatus.

The fan blades 1.8 project beyond the periphery of the revolving disk as shown and are enlarged at their outer encs as at 20, so as to project up .approximately to or `above the revolving .disk '14 to engage the screw bolts to the upper stationary disk, and

also on one or both pairs of cross beams 21 f which are secured to the supporting member 8, which as previously explained carry the upper stationary disk or plate 7.

The lower .plate 14 as before stated, is secured to the upper end of shaft 10, which latter is vmounted in the vertical bearings 15 and is provided with the pulley 16 by vas which it is rotated.

In the operation of the apparatus the material which may be cane or other stalks, or other material, to be disintegrated, is fed into the machine by gravity through a hopper or hoppers located above the opening 6 or openings in the upper plate 7. As the lower plate is rapidly revolved by a belt or a pulley 16, or by any suitable gearing, or by a direct connection with a vertical motor, the material will be thrown by centrifugal force outwardly between the shears on the upper and lower plates and coming in contact with said shears will be disintegrated into a fibrous mass, and thus put it in a' condition to be readily passed between juice extracting rollers without any further crushing. The lower knives being scimitar shaped also have a tendency to aid the progress of the material from the center ofV the plates out toward's the discharge openings between the plates. The knives are held to their res ective upper and lower plates by means o bolts the heads of which are located in countersunk holes in theknives or cutters.

The shredded fibrous sections after they are ejected from between the two disintegrating disks is thrown into the trough or shield 17 and is carried by the fan blades 18 around to the discharge spout 19, which preferably dischar es onto a conveyor which carries the firous sections up or to the juice extracting apparatus which latter may be of any approved type. j

While the drawings show the upper disk stationary and the lower disk revolving, I do not wish to limit myself to this arrangewith said shield and means actuated by the I will be cut or shredded into fibrous hay-like ment but that the upper disk might also be revolving in a direction opposite to the direction of rotation' of lower disk. The product of the machine is a result of the relative rotation of the two disks, and this relative rotation can be obtained by either having one of the disks'stationary and revolving the other, or as stated above, by revolving both of the disks but in opposite directions.

It is evident that many slight changes might be resorted to in the relative arrangementof parts shown and described without departing from the spirit and scope of the invention, hence would have it understood that it is not desired to be confined to the exact construction and arangement of parts shown and described is claimed as new and desired to be secured by Letters Patent, is
