COTTON BLENDING AND CLEANING APPARATUS.

SPECIFICATION forming part of Letters Patent No. 763,798, dated June 28, 1904.

Application filed March' 1, 1904. SerialNo. 195,982. (No model.)

To all whom it may concern:

Be it known that 1, CHARLES E. SAMPLE, a citizen of the United States, residing at Terlton, in the county of Pawnee, Oklahoma Territory, have invented new and useful Improvements in Cotton Blending and Cleaning Apparatus, of which the following is a specifica tion. My invention relates to new and useful improvements in cotton blending and cleaning apparatus adapted to be used in connection with cotton-gins or otherwise; and its object able receptacle provided therefor and to au tomatically feed the clean cotton to the ginstand. 1

A further object is to provide means whereby the. cotton may be carried by suction through the cleaning apparatus.

Another object is to provide novel means for separating and mixing the cotton, so as to blend any stained cotton with the white material, so as to render the stained stock invisible to the eye after the ginning operation, thereby saving the usual reduction in the price upon the mass because of the discolored cotton.

The invention consists in the novel construction and combination of parts hereinafter more fully described and claimed, and illustrated in the accompanying drawings, showing the preferred formof my invention, and in which Figure 1 is a vertical section. Fig. 2 is a section on line'2 2, Fig. 1. Fig. 3 is a section on line 3 3, Fig. 1. Fig. 4 is a perspective Fig. 5 is a horizontal section through the feed-wheel.

Referring to the figures by numerals of reference, 1 is a frame of any suitable construction having a casing 2 supported thereon, the bottom of which forms a hopper 3, having an outlet-pipe 4E. Arranged Within the casing is a frusto-conical jacket 6, which extends partly over the hopper 3 and communicates at its upper end with an air-tight hood 7. A shaft 8 is journaled within the frame 1 and extends through the'center of the casing 2 and jacket 6 and also through the hood 7. This shaft is provided with a pulley 9 or other suitable means, whereby it may be rotated by any suitable power. Within the hood 7 is a feedwheel 10, which is secured on the shaft 8 and is adapted to be rotated thereby. This wheel is formed of a series of laterally-extending wedge-shaped partitions 11, the upper ends of which are covered by a screen 12, and is incased with a band 30 around the outer extremity of said partitions and screen, as shown in Fig.

1. This wheel is eccentrically arranged within the hood 7 and is supported by the shaft 8 above a partition 13, which projects into the hood and has a tight-fitting cover l3 and a downwardly-extending flange 14:. This flange and one of the sides of the hood 7 form a hopper 15, the outlet of which is in vertical alinement with the chamber formed between the jacket 6 and a hollow frusto-conical roll 16, secured to the shaft 8 and concentric with the jacket 6. Partitions 17 connect the shaft with the roll, and both ends of the roll are closed by disks 16 and 16", the upper end being provided with an air-inlet 5. The lower end of the roll 16 and'fan-blades 27, secured to said end, are revolubly mounted above and adjacent the bottom 18 of the jacket. A circular tube 20 incloses the aperture 5 and extends upward from the roll 16 to a point above the lower edge of flange 14:, and this circular tube forms an inlet-tube through which air may beadmitted to the roll 16. Fan-blades 21 extend laterally from the tube 20 and are provided at their outer ends with inclined teeth or projections 22. The tube 20 is connected apertures 24 are thus formed in the roll for the escape of air entering the inlet 5 and forced outward by the rapidly-rotating fan-blades 17. A number of apertures 25 are formed in the jacket 6. An outlet-tube 26 extends from one side of the jacket 6, at the bottom thereof, and extending from the shaft 8 in horizontal alinement with this outlet-tube is the series of fan-blades 27, before referred to. The outlet-tube in cross-section is preferably of the form illustrated in Fig. 3, and it will thus be seen that when the blades 27 are rotated in the direction of the arrow in Fig. 3 any material in the paths thereof will be thrown and blown outward into the tube 26. This tube communicates with a feed-tube 28, arranged at the upper ends of a gin-feed 29, and the outer end of the tube is normally open. A diagonally-arranged screen 31 extends transversely across the tube 28, the inclination being such as to direct outward any material brought into contact therewith from the tube 26.

A suction-tube 34 opens into the partition 13 at a point below the wheel 10 and in vertical alinement with the end of a suction-tube 33, and this tube 34 is preferably provided with a vertical portion 34, at the base of which is arranged a receptacle 35 for the reception of stones and other heavy foreign particles. This receptacle is preferably normally closed at the bottom by means of a cap 36.

The teeth 22 move beneath guide-plates 22, secured to the inner face of the jacket 6 at its upper end,and forcethe cotton into the space between the roll 16 and the jacket 6. The seed-cotton is sucked into the cleaning apparatus through the pipe 34, and in passing the receptacle 35 all heavy particles carried therebysuch as stones, &c.will fall by gravity thereinto and can subsequently be removed by first detaching the cap 36. The cotton is drawn upward into the feed-wheel 10 by the suction of air through tube 33,and its upward movement is'stopped by the screen 12. As the wheel 10, together with the fans 21, 27, and 17 and the roll 16, are rapidly rotated with the shaft 8,it will be understood that the cotton will be quickly carried into the hopper 15 by the wheel 10 and will drop therethrough by gravity, assisted by air which is drawn into the hopper 15 through tube 10 by fan-blades 21. When the cotton comes in contact with the blades 21 and the inclined teeth 22 thereon, it will be forced under the guide-plates 22 upon the jacket 6. The air from tube 10 and a portion of the dirt and dust contained in the cotton will be blown out by centrifugal force through apertures 25 in jacket 6, and the cotton will be forced downward by the rotation of the roll 16 and teeth 22 and will be forced by inclined guide-plates 22 into the space between the jacket 6 and the roll 16.

Air enters the roll through the inlet 5 and is forced outward by centrifugal force from the rapidly-rotating fan-blades 17, which revolve with the roll. This air as it passes through the apertures 24 blows the cotton which is between the roll and jacket firmly into the apertures 25 in the jacket 6, and it is rapidly thrown from these apertures by the teeth on the roll 16. The cotton is also thrown by centrifugal force against the apertured jacket with such force as to separate loose particles of foreign material from the cotton and force them through the apertures. The cotton is thus thoroughly separated, each seed from the others,with its adhering lint, and the air passes through it and carries all dust and rubbish, mildew, or mold through the apertures 25 into the casing 2, from which it is blown outward through the pipe 4,. The cotton is carried downward and around the jacket 6 in-a spiral course as it is alternately blown into apertures 25 and thrown from them by teeth 24 as they rotate with the roll, and it is blown and thrown'against the inner inclined sides of the hollow frusto-conical jacket 6, and this spiral downward movement of the cotton is assisted by the air discharged through the apertures in the roll and which is directed downward by the inclined teeth on the roll. Then the cotton reaches the bottom of the compartment formed, between the jacket and the roll, it is forced under plates 22 at the bottom of the jacket 6 and is discharged therefrom by the teeth 22 on the fan-blades 27, which throw and blow it into the tube 26 and against the screen 31, and it drops therefrom into the gin-feed 29. During the downward course of the cotton between the perforate jacket 6 and the roll 16 it is continuously subjected to the cleaning effect of the air-blast or air under pressure delivered thereagainst centrifugally with respect to the shaft 8 and the blades 17 thereon, and thereby forced outwardly against the jacket and over the openings 25, the latter being cleared regularly by the downward feed-action of the teeth 24:, as before set forth; but the retention-of the cotton against the jacket 6 over a portion at least of the openings 25 is materially beneficial inthe cleaning operation, in view of the fact that the cotton is held in one position for a greater length of time and more thoroughly subjected to the cleaning influence of the air forced outwardly thereagainst. During the time that the cotton is held against the jacket 6 over the openings in the latter a resistance is temporarily set up to the escape of the air through said openings in an outward direction, and by this operation the air is more fully utilized in cleaning the cotton by reason of being forced to some extent therethrough. The most effective cleaning operation ensues between the planes of the plates or disks 16 and 16 and. as the outwardly-forced or centrifugally-applied air without obstruction would have the tendency to pass out or escape in the direction of least resistance it would pass downwardly scares toward the bottom 18 of the jacket 6, and a large part thereof would escape into the discharge-tube or outlet 28. This operation would take place in view of the closure of the openings by the cotton forced thereagainst, and the cleaned and blended. To obstruct this downward movement and escape of the air, the fanblades 27, providing a pneumatic resistance, are located in the bottom of the jacket under the lower disk or plate 16", and though this lower pneumatic resistance means does not interfere with the mechanical feed ofthe cot-- 'ton toward the discharge it does operate to counteract the loss of any of the forceful effect of the air thrown outwardly through the roll or toothed device and jacket,- especially in view of the fact that each of the 'fans or air-pressure creating devices has independent air current-feeding means. In other words, the strata of air-pressure created by the fan arranged externally of the enlarged extremity of the roll is sufiicient in resistance to hold the air-pressure forcing the cotton outwardly against the jacket within the cleaning-space between the planes of the disks or plates 16 and 16 The upper fan, or that within the reduced extremity of the roll 16,

also forces air outwardly against the cotton at the point where the latter enters the space between the roll and jacket to perform an initial cleaning step, and this fan also operates as a resistance means to prevent the escape of the air thrown outwardly by the intermediate 1 fan comprising the blades 17 through the feed end of the machine and obstructs any tendency to retardationof the feed of the cotton by the-means heretofore explained. Thus it will be seen that a pneumatic resistance means is located at opposite extremities of the main cleaning portion of the space between the roll and jacket where the most effective cleaning and blending of the cotton takes place. It will be observed that the resistance or obstruction of the fan-blades 27 to the loss or escape of the pressureof the blades 17 is materially assisted by contracting the outlet 26, such contraction or restriction of this outlet causing the air-pressure of the fan comprising the blades 27. to be thrown upwardly. One or more gin-feeds may be thus filled, for when the cotton fills up to the screen 31 in the farthermost connected ginfeed the air-current is thereby; retarded and the cotton falls nearer to the fans 27 until the cotton against the screen is worked down. The cotton is then blown against the screen as before. I r

By providing a jacket of frusto-conical form the passage of the cotton toward the outlet 26 is facilitated for the reason that each time the cotton is drawn out of the apertures in the jacket by the teeth on roll 16 it is driven back against the jacket, but at a point nearer the discharge end thereof.

cotton would -not be as thoroughly ning.

and cleaning seed-cotton by I uponthe wings, and means ,nicating with said tube,

It will be understood that in addition to cleaning cotton the apparatus can also be used for commingling stained cotton with white cotton, soas to prevent the. loss which is occasioned by the reduced price given for discolored stock.

The apparatus may also be employed for drying the cotton which is too damp for gin- The apparatus can be disconnected from the cotton-gin and used for blending first removing cover 13 and feed-wheel 10. Cotton can then be placed in the hopper and will be operatedupon by the teeth'22 and plates 22, as hereinbefore described. An air-inlet tube 10 is so arranged within the hood 7 as to permit air to the center of the fan 27. This air is thrown outward by the fans for the purposes hereinbefore set forth.

In the foregoing description I have shown the preferred form of my invention; but I do not limit myself thereto, as I am aware that modifications may be made therein without departing from the spirit or sacrificing anyof the advantages thereof, and 1 therefore reserve the right'to make such changes asfairly fall within the scope of my invention.
