EDWARD A. JOHNSTON, OF CHICAGO, ILLINOIS, ASS IGNOR TO INTERNATIONAL HAR VESTER COMPANY, A CORPORATION OF NEW JERSEY SPIRAL GONE CGTTQN CLEANER Application filed July 9, 1930. Serial No. 466,766.

This invention relates to a device for cleaning newly picked cotton.

The principal object of the invention is to provide an improved type of cleaner for removing dirt, leaves and similar material from cotton, particularly from cotton that has been Only such structure is shown in the drawings as is necessary to illustrate the principle of the device and to show such parts as are necessary for its functioning. A pair of brackets 1 and 2 are attached to a base 3 and provide means for supporting the device. The bracket 2 is much higher than the bracket 1, to provide means for supporting the cleaning device in an inclined position orat an angle. The brackets 1 and 2 have arched upper portions 4 and 5, which are arranged in substantially the same plane. An annular plate 6 is secured to said arched portions 4 and 5. A series of rods 7 are secured at their lower ends to the annular plate 6 and extend angularly upwardly to a similar annular plate 8, which is positioned parallel to the plate 6; The rods 7 are also'secured to the plate 8. At the lower ends of each of the rods 7, a bearing spool 9 is mounted for rota tion. Said spools are provided with grooved portions 10, which form bearings for taking both radial and axial thrust from an annular member 11, which is mounted for rotation in thegrooves 10 of the spools 9. A series of bars 12 attached to the annular member 11 extend upwardly to a similar annular member 13, to which they are also secured.

A second series of spools 10 are radially mounted at the top of the bars 7 The annular member 13 is positioned in contact with the spools 10, which form aligning bearings therefor. The annular plates 11 and 13 and the bars 12 form a drum structure which is rotatable, as will be hereinafter described. As shown in Figure 2, there are four of the bars 12. From each bar, a plate 14 secured to the bar extends radially inwardly. A series of stepped notches 15 are formed in the plate member 14, said notches at the top of the bars 12 being immediately adjacent the bars and being successively closer to the axis of the annular members 13 and 11 as the bottom is approached. The notches 15 are spaced apart a suflicient distance to form inwardly extending cars 16. Said ears terminate with their ends substantially parallel to the axis of the drum structure. A spiral strip 17 is wound around the inside'of the plate members 14: with the outer circumference of the spirals abutting against the ends of the ears 16. Said spirals are'regidly. secured to the cars by soldering or other suitable means. At the top of the annular plate 13, a cylindrical extension 18 provides means for attaching a pulley 19. The pulley 19 is adapted to be operated by any suitable means for rotating the drum structure.

In the operation of this device by means of a belt or other suitable means power is applied to the drum structure by means of the pulley 19. The entire drum structure rotates with the spools 10 and 10 serving as aligning bearings and taking axial and radial thrusts. Cotton to be cleaned is delivered in regulated amounts into the interior of the drum structure through the center of the hollow cylindrical pulley 19. As the drum rotates,.the dirt, leaves and other such material in the cotton is shaken loose and is thrown outwardly against the spirals of the strip 17. As best shown in Figure 3. the successive spirals are spaced apart a sufiicientdistance to allow the undesirable material to escape there-between. The cotton works its way downwardly and is discharged out of the bottom of the drum structure. The particular angle at which the drum structure is positioned and the relative sizes of the parts may be altered to secure the best cleaning of the particular material being handled. The drum structure may also be rotated at the speed found most desirable.

It is to be understood that applicant has shown only a preferred embodiment of his improved device for cleaning cotton and that he contemplates as his invention any modification thereof falling Within the scope of 5 the appended claims.

hat is claimed is:

1. A :cotton cleaner comprising a hollow drum structure mounted on an upwardly extending axis, an opening at one end of said 10 structure for feeding cotton thereto, an open ing at the other end for the discharge of cotton therefrom, said drum structure being formed from a strip of material Wound spirally with the adjacent convolutions spaced axially and radially, and means for rotating said structure.

2. Acotton cleaner comprising asupporting structure, bearing means arranged at the base of said structure, bearing means arranged at the top thereof, a drum structure mounted for rotation on said bearing means, a pulley mounted on said structure for rotaition thereof, a conical separating member forming a portion of said drum structure, said member having a plurality of spaced wall portions formed from a strip of :material wound spirally with the adjacent .convolsutions spaced axially and radially, an opening at the top ofthe drum structure 01 1115' feeding cotton thereto, and an opening atthe bottom forthe discharge of-cotton therefrom.

In testimony whereof I .a ffiX my signature.

EDWARD A, JOHNSTON.
