8 Claims. 1
This invention relates to cotton cleaners and has for an' object the provision of apparatus of the character designated which shall embody a plurality'of cleaning cylinders upon which the cotton is supported while being cleaned, and over which it is moved, and has foran object the provision'oiapparatu's ofthe character designated which shall include improved means for 'effecting a more thorough separation of the cotton and trash, and shall also include means for reclaiming cotton out of the foreign matter separated initially from the cotton.
A yfurther object of our invention is the provision of cotton cleaning apparatus embodying cleaning elements which shall be especially adapted for separating green leaves and sticks from cotton as it comes from the eld.
'In the previously liled application of Lucien L. McDaniel and Frank E. Deems,'Serial No. 547,371, led July 31, 1944, and now Patent No. 2,384,383, granted September 4, 1945, assigned to Continental Gin Company, there'is shown,`described and claimed a cotton cleaner which includes a row of cleaning cylinders each comprising a multiplicity of cleaning elements which are spaced apart suficiently to permit trash to fall therebetween but are close enough together to support the cotton being cleaned. The cylinders also are similarly spaced apart with respect toV each other to permit trash to pass. The apparatus therein disclosed has proved highly efficient in the separation of green leaves and sticks from Vcotton as it comes from the field, but in operation, a certain amount of cotton passes between the cleaning elements and between the cylinders together with the foreign matter. It is a prime purpose of this invention therefore toY provide'means for separating cotton out of the trash thus discharged between the cleaning elements and to return the cotton thus reclaimed to the cleaning apparatus for repassage.V
In accordance with this invention, we employ similar cleaning cylinders and incline the row of cylinders upwardly. The cotton travels upwardly over the upper surfaces of the row of` cylinders, allowing the trash to fall downwardly between the cleaning elements and between the cylinders moving by gravity toward the lower end of the row. At the lower end of the row, we provide a reclaiming saw cylinder together with a doffer and means associated with the dofier to return the cotton to the row of -cleaning cylinders. In order to agitate the cotton, we may provide an upper row of agitating cylinders to cooperate with the lower row ofcleaning cylinders, as in the previously led application of McDaniel and Deems aforesaid.A Furthermore, the elements upon which the cotton is supported while being cleaned may comprise the relatively thin disks hereinbefore mentioned or'they may comprise spiked cylinders or `disks of a 'shape other than circular, but which are so shaped and' spaced as to support and clean the cotton as it is moved thereover.
Apparatus embodying features of our invention is illustrated in the accompanying drawings, forming a part of thisapplication, in which Fig. 1 is a longitudinal sectional view showing one form of our apparatus;
Fig. 2 is a sectionalview taken along the lines II-II of Fig. 1;
Fig. 3 is a longitudinal sectional view showing a modified form of apparatus;
Fig. 4 is a detail sectional View showing apparatus embodying a modified form of disks for supporting the cotton as it is being cleaned;
Fig. 5 is a fragmentary sectional view showing a modied form of cleaning cylinder, and
Fig. 6 is a view similar to Fig. 1 showing a still further modied form oi our invention.
Referring now particularly to Figs. 1 and 2 of the drawing, we show an elongated upwardly inclined casing IQ, having a downwardly slanting bottom II. Cotton to be cleaned is admitted into the casing through an opening 9 located in the top wall near the lower end of the casing. The cleaned cotton is discharged from theV casing through an opening I2 in the bottom, disposed near the upper end of the casing. Dirt and trash separated from the'cotton is discharged from the casing through an opening I 3 at the extreme lower end cf the casing. Disposed within the casing Illis a row I5 of cleaning cylinders, each comprising a multiplicity of relatively thin metal disks I4 mounted on a shaft IB, and spaced apart on the shaft IB a sufficient distance to permit trash to iall between the elements but close enough to support the cotton on the upper surface of the cylinder. We have found that a spacing of approximately inch gives satisfactory results. The disks I4 are preferably serrated as shown with relatively coarse teeth to aid in moving the` cotton upwardly along the upper surfaces of the row of cleaning elements and to aid in agitating the cotton while being cleaned.
The cylinders forming the cleaning elements are rotated by any suitable means, not shown, in the directions indicated by the arrows in Fig. 1 so as to carry the cotton from the lower end of the casing toward the upper end.
Mounted above the row of cleaning cylinders just described, is a row of agitating cylinders Il which are provided with agitating elements which may comprise spikes I8. The row of agitating cylinders I7 is spaced directly above the cleaning cylinders and the cylinders are rotated by any suitable means, not shown, in the directions shown by the arrows, lthat is, in a direction opposite to the direction of rotation of the cleaning cylinders, Cotton to be cleaned is fed through the opening 9 onto the upper surface of the agitating cylinders Il and is carried downwardly onto the upper surface of the row of cleaning cylinders I and from thenceis carried upwardly over the upper surfaces of the cleaning cylinders to the cotton outlet I2. The cleaning cylinders I5 each act to toss the cotton upwardly toward the agitating cylinders, where it is engaged by the spikes I8 and is tossed back against the next succeeding cleaning cylinder. The cotton is thus tossed back and forth between the cleaning and agitating cylinders in its travel from the lower end of the casing .toward the upper end; At the same time the cleaning cylinders engage the leavesand trash in the cotton and separate them from the cotton.
Leaves and trash passing between the thin disks I4 of the cleaning cylinders fall downwardly on the bottom II of the casing and move downwardly along said bottom to the lower end of the casing. Therow of cleaning cylinders I5 is closely spaced with respectto the bottom so that if the trash should bank up on thebottom II it will -be engaged by -a cleaning cylinder and moved downwardly. At the lower end of the casing IB is a screen 2I and mounted directly over the screen 2| is areclaiming saw cylinder 22 The saw cylinder 22'is disposed to engage the trash with such cotton -as may have passed between the disk I4 and separate the cotton from .the trash before it is finally discharged through the screen 2|. The .cotton separated from the trash is removed from the reclaiming cylinder 22 by means of a doffer cylinder 2-3 and is carried upwardly to be engaged by a kckerroll 24 which discharges the cotton thus reclaimed onto the cleaning cylinders I5 whereupon it moves over the cleaning cylinders Vagain with the other cotton being introduced through the opening 9.
In Fig. 3 of the drawing we show a modified form of our invention, in which we omit the row of agitating cylinders Il. Inaccordance with this modification, we provide a row of cleaning cylinders 3i) mounted in a casing SI in a manner similar to the row of cleaning cylinders I5 already described. Each of the cleaning cylinders comprises a multiplicity of relatively thi-n serrated disks 35 over which the cotton travels to be cleaned, which disks are mounted and spaced similarly to the disks I 4 already described. In the upper part of the casing 37|, we provide .baille members 32 above the cleaning elements 3, which are so positioned that cotton is thrown upwardly against them by the rapidly rotating cleaning elements, and falls downwardly onto the next succeeding cleaning elements. Adjacentthe row of cleaning elements 3U, near the lower end thereof, is a reclaiming saw cylinder 33, having a doifer Sil associated therewith, and a kickerroll 36 positioned to return cotton picked up by the reclaiming saw to the row of cleaning cylinders 3. In all other respects this modification is similar to that already described in connection with Figs. 1 and 2.
In Fig. 4 of the drawing, we show a still fur- CTI adjacent shaftsther modified form of our invention in which the cleaning elements 40 of the cleaning cylinders are mounted on shafts 4I, and instead of being circular in shape, are in the form of elongated plates having opposed parallel straight sides 42 and oppositely curved ends 43 and 4'4. The plates on one shaft 4I extend between the plates on adjacent shafts and are mounted with their longer dimensions at right angles to the plates on At the lower end of the row is a stationary assembly of plates 46 cooperating with the lower cleaning cylinder, and at the upper end is a second stationary assembly 4'! cooperating with the upper cleaning cylinder to form a continuous supporting surface. There is thus provided a continuous supporting surface for the cotton comprised of thin relatively closely spaced elongated plates. The cleaning cylinders are rapidly rotated in the directions shown by the arrows and act to throw the cotton being cleaned upwardly against baille membersr 48 which aid in separating the dirt and trash from the cotton. The row of cleaning cylinders and the casing therefor, in accordance with this modification, are upwardly inclined as in the other modifications hereinbefore described, and a reclaiming saw 49 is located at the lower end of the casing as in'the previously described modiiica'tions.
In Fig 5 is a still further modified form of cleaning cylinder in which the cleaning elements are in the form cf spikes 5D, mounted on a-drum 5I and so spaced as to provide passage Ifor dirt and trash between them and to provide a supporting surface for the cotton being cleaned.
The apparatus Ishown in Fig. 6 of the drawing is similar in all respects to that shown in Fig. 1 except that a perforated screen 53 is provided below the cleaning cylinders I5 through which sand, dirt and ne trash separated from the cotton in the cleaning operation can pass and fall on a solid bottom SII, down which it moves by gravity to the outlet I3, without beingengaged bythe reclaiming saw cylinder 22. The .larger trash, sticks and leaves, to which particles of cotton may cling, move down the perforated bottom 53 to the lower end where they are engaged by the reclaiming saw 22.
From the foregoing description, the operation of our improved cotton cleaner will be readily understood. Cotton as it comes from the field containing green leaves, trash, dirt and other foreign matter is fed into the casing through the opening 9, or into a corresponding opening in the vmodified forms shown, and is caused to travel over the upper surfaces of the cleaning cylinders. In the form shown in Fig. 1 of the drawing the cotton is further agitated by means of the spiked agitating cylinders I'I and as the cotton travels upwardly over the cleaning cylinders I5, the leaves, dirt and trash are separated therefrom and fall downwardly between the cleaning elements onto the bottom II of the casing. It there travels by gravity downwardly toward the lower end of the casing, where it is engaged by the reclaiming saw 2-2 which separates any cotton therefrom that may have accompanied the trash, and the trash passes through the screen 'El to the outlet I3. The cotton separated from the trash by the reclaiming saw 22 is doifed by the doifer 23 and is returned by the kicker roll 2d to the row of cleaning cylinders I5. The cleaned cotton is discharged `through the outlet I2 near the upper end of the casing IB. In the form of apparatus shown in Fig. 6 of the drawing the sand, dirt, and fine trash pass through the perforated bottom 54 and thence down to the outlet I3 Without Ibeing engaged by the reclaiming saw cylinder 22.
'Ihe operation of the apparatus shown in Figs. 3 and 4 is similar to that described-for Figs. 1 and 2 except that there isomitted the upper row of'agitating cylinders, l1 .and the cotton ,being cleaned is. thrown byaction of the cleaning elements up against `Vthe baffles 48 in the upper part of the casing, which action aids in separating thedirtand loose trash from the cotton'sothat it may fall downwardly between the disks asl hereinbefore described. In all the forms of our invention it will be seen that the upward inclination of the row of cleaning cylinders and the casing therefor causes the return of the trash to the lower end of the casing where it may be acted upon by the reclaiming saw cylinder.
From the foregoing it will be apparent that we have devised an improved cotton cleaner which embodies cleaning elements in the form of relatively thin, closely spaced disks, so disposed as to provide a supporting surface for the cotton being cleaned as well as an active cleaning mechanism, and provide in association therewith means for reclaiming any cotton which may accompany the trash passing between the closely spaced disks.
While we have shown our invention in several forms, it will be obvious to those skilled in the art that it is not so limited, but is susceptible of various other changes and modifications, without departing from the spirit thereof, and we desire, therefore, that only such limitations shall be placed thereupon as are specifically set forth in the appended claims.
