To all whom it may concern:

Be it known that I, MARGARITO CABRERA, a citizen of the Republic of. Mexico, residing at San Antonio, in the county of Bexar and State of Texas, have invented certain new and useful Improvements in Cotton-Cleaners; 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 cotton cleaners, and the primary object of the invention is to provide a cotton cleaner wherein the cotton is drawn into and through the cleaner by air suction, which cleaner casing is provided with a pair of hinged sections, so that the interior of the cleaner may be easily and quickly released, and also so that in case the cotton within the cleaner catches fire, the

sides may be opened, allowing the rotor of the cleaner to throw the dirt cotton out of the cleaner, and owing to the fact that cotton is drawn into and through the cleaner by air suction, the feeding of the cotton into the cleaner will be arrested because the opening of the sides of the casing will break the direct line of air suction.

Another object of this invention is to provide a cotton cleaner as specified whichineludes a'plurality of rotary members having radially extending webs carried thereby which carry the cotton over foraminous screens through which the foreign matter is forced, which structure is arranged for thoroughly cleaning the cotton fiber without twisting the same and further to provide agitators at the end of the cleaner which will fluff or loosen the cotton prior to and after passage through the cleaner.

\Vith the foregoing and other objects in view this invention consists in such novel features of construction, combination and arrangement of parts as will be hereinafter more fully described, illustrated in the accompanying drawings and claimed.

In describing the invention in detail reference will be had to the accompanying drawings wherein like characters designate like and corresponding parts throughout the several views, and in which Figure 1 is a side elevation of the improved cleaner having the parts thereof broken away,

Fig. 2 is a horizontal section through the improved cleaner,

' rotors 1 1 and 15.

Fig. 3 is an end view of the cleaner,

Fig. 4c is a vertical section through the cleaner,

Fig. 5 is a detail perspective view of one of the rotary members of the cleaner, and

Fig. 6 is a fragmentary section through the cleaner illustrating one of the agitating or fiuifmg members.

Referrlng more particularly to the drawings, 1 designates the casing of the cotton cleaner, which is substantially heart shaped.

A flue 2 is carried by the top of the casing l and it has valves 3 and 1 positioned therein as clearly shown in Fig. 1 of the drawings. Any suitable type of air suction device may be connected to one end of the fine 2 for drawing cotton inwardly into the cleaner through the. end 5 and outwardly out of the cleaner through the end 6. The valves 3 and 4 are provided for regulating or cutting ofl the air suction.

' The sections 7 and 8 of the casing 1 are hingedly connected as shown at 9 to the flue 2, so that they may be moved outwardly for permitting access to the interior of the cleaner if it is so desired.

A plurality of supporting braces 10 are positioned at spaced distancesiinteriorly of the casing 1 and they support the lower sections of the foraminous screens 11. The sections 7 and 8 have portions 12 of screen attached thereto the lower edges of which meet with the edges of the portion 11 as clearly shown in Fig. 4; of the drawings for forming a continuous foraminous lining within the cleaner over which the cotton is passed through the rotary action of the The rotors 1 1 and 15 are mounted upon shafts 16 and 17 respectively, which shafts are rectangular intermediate their ends, upon which rectangular portions the rotors are mounted. The shafts 16 and 17 project outwardly out of the ends of the casing and they are supported by suitable bearings or pillow blocks 18. The shaft 16 has a driving pulley 19 mounted upon one end of the same and a gear 20 mounted, upon the other end. The gear 20 meshes with a "gear 21 which is mounted upon the shaft and extend longitudinally of the cylindrical cores 23, so as to carry the cotton over the screen structures 12 and-11' Without twisting the fiber or strands of the cotton.

The shafts 16 and 17 have agitators or fiufl'ers 25 mounted thereon at each end of the casing 1. The flutfers 25 include hub sections 26 which have a plurality of radiating blades 27. The blades 27 during the rotationof the fluffers 25 engage thecotton fiber as it enters the casing 1 and loosen or flufis it so that the cleaning action of the rotors 14 and 15. may be facilitated while the agitators or fluffers 25 which are positioned at the delivery end of the cleaners loosen or fluff thecotton prior to its passage from the cleaner to a gin. 7

An auger conveyer 30 is positioned in the bottom of the casing 1 and it is provided for carrying off the foreign matter which is rubbed from the cotton fiber.

The cotton is drawn into the cleaner throughthe end 5 of the flue 2 by air suction and upon its entrance into the casing 1 it is engaged by the flutters 25positioned at the receiving end of thecleaner which loosen or fluff the cotton. The cotton is then, drawn through the casingby the air suction, and it is carried over. the screen linings 12 and 11 by the action of the rotors 1 1 and 15 which will rub dirt, small, particles of stems,1 pods or leaves from the fiber and through the screens 12 and 11 into the lower portion of the casing 1, from which it is conveyed by the auger conveyer 30. The cleaned cotton will be drawn outwardly through the end 6 of the fine 2 for passage through a gin or storage house as desired.

In case the cotton Within the cleaner catches fire, the hinged sections 7 and 8 of the casinglmay be moved outwardly, which will permit the rotation of the. rotors 14 and 15 to throw the cotton out of the cleaner upon the floor. l/Vhen the sides 7 and 8 are open, the air suction through the cleaner will bebroken, and consequently the feeding of cotton into the cleaner will be arrested. Immediately after the sides are again closed, the air suction Will be complete and the feeding of the cotton. will; be resumed,

From the foregoing description taken in connection with the accompanying drawings, the advantages ofconstruction and of the methodof operation of the improved.

cotton cleaner will, be readily. apparent, to those skilled in the art to which this invention appertains, and while in the foregoing description, the principle of the operation of this invention has been described'togcther with various features of construction, it is to be understood that certain minor features of construction, combination and ar rangement of parts may be altered to suit practical conditions provided such alterations are comprehended within the scope of what is claimed.

hat is claimed is In acottoncleaner structure, a rotor comprising a core, a plurality of radiating blades carried by said core constructed of sheet metal bent to form curvedi core engaging portions and having one longitudinal edge thereof bent outwardly at right angles to form straight radiating blade portions,
