This housing emdruinand extending radlally outwardthere bodies a pair of end wallsll of generally from area plurality of teeth 28 arranged in rectangular formationhaving the corners longitudinal rows on the wa l'l of the drum. formed at an angular inclination as will be plate 29 is secured in horizontal popresently indicated. Rigidly secured besitionj 1n the rear wa'll'ot the housing, this plate being adapted to prevent the cotton being carri d into the upper portion of the housing. V

Secured in position immediately below the under side of the drum and spaced from the teeth thereof is a foraminous screen 30 substantially semi-circular in cross section. The forward edge of the screen 30 is secured to the beam 19 while the rear edge-is attached to the inner edge of the beam 20. From this construction it is apparent that the screen 30 is disposed between the drum and the arcuate bottom plates 21 and 22.

Rotatably mounted in the trough 12 is a longitudinal spiral conveyor 31. The ends of the conveyor 31 are formed with spindles c 32, one end of the conveyor being rotatably supported in one of the end walls 11 while the opposite end projects through the opening 13 formed in the respective end wall and is rotatably supported in a bearing bracket 33 mounted on said wall.

In operation, y improved cotton cleaning. machine is disposed adjacent a boll extractor and arranged so that the discharge of the extractor will be positioned against the intake opening of the machine. The auxiliary cleaning machine is arranged on a level with the top of the gin stand a little to the rear of the same so that the discharge opening of the cleaning machine is'arranged the cotton between the rotary in registration with the intake of the gm stand. As the cotton passes through the boll extractor, which may be of the type known as the Mitchel boll extractor, the bolls are removed but foreign matter such as shale remains mixed with the cotton. Ordinarily, this foreign matter is fed into the in stand so that a comparatively low grade of cotton is produced. the. auxiliary cotton cleaning machine scribed in the foregoing, the particles of shale and other foreign matter are thoroughly separated from the cotton, by agitating V toothed drum and the foraminous screen 30.

Asthe foreign matter is separated from the cotton, it is forced through the foraminous screen and discharged into the trough 12. The particles of shale are then conveyed longitudinally through the trough .and discharged into a suitable receptacle.

The machine is driven by means of a belt trained about the drive pulley 24: which will. rotate the shaft 23 and drum. As clearly indicated in the drawings, a sprocket wheel 34 is rigidly secured to the projecting end of the conveyor shaft 32, this wheel being arranged in a vertical plane with the sprocket 25 secured to the drum shaft 23 and driven by means of the chain 35 trained over the sprockets. From this construction it will be noted that the conveyor is continuously rotated during the rotary movement of the a bearing opening formed in shape,

When employing conventional type of boll extractor and gin i stand to effectively remove extraneousmatter fromthe cotton so as to produce a, relativelyhigher standard of product. I

It is to be understood that the form of my invention herewith shown and described is to be'taken as the preferred example of the same, and thatvariOus changes asto the size and arrangement of parts may be resorted to without departing from the spirit of the invention or the scope of the subjoined claim. 4 y

Having thus described my invention, I claim: i

In a cotton cleaning machine, an elongated,

hollow body comprising a top wall, a relatively shallow the forward sideof the'to'p wall, and a downwardly and rearwardly inclined rear wall extending from the rear side of the front wall, a relatively shallowvertical wall section extending longitudinally at the lower edge of the said inclined rear wall, an upwardly and forwardly inclined beam, the body of the cleaner further including end walls, the said beam extending betweenthe ends walls in spaced relation to and in a plane below the lower edge of the front wall, a rearwardly and downwardly inclined member extending. between the end walls and in a plane below and spaced with respect to the lower edge of the vertical rear wall section, a drum rotatably mounted inthe body and having its circumference located relatively close to the lower edge of the front wall and the lower edge of the said beam, the said surface of the drum being located relatively close to the upper forward edge of the member which extends below and in spaced relation to the lower edge of the vertical rearwall section, a baffle extending longitudinally between the end walls of the body and forwardlywithin the body from substantially the upper edge of the said vertical rear wall section with. its forward edge located relatively close to the front wall depending born and upper edge of the member which is lo cated below and in spaced relation to the.

vertical rear wall section, the said screen being curved concentric to thesaid drum, a trough extending longitudinally beneath the drum substantially in the vertical plane of the axis of rotation of the drum, imperforate bottom members extending on curved lines between the said beam at the front of the body andvthe forward upper side ofthe trough and between the upper rear side of the trough and the said member which extends below and in spaced relation to the vertical rearwall section, a screw conveyor operating in said trough, and

means for imparting rotary motion simultaneously to the said drum and to the said conveyor.

In testimony whereof I afiix my signature. STEPHEN HARVEY ASSITER.
