' COTTON-CLEANER.

To all whom it may concern Be it known that I, SAMUEL WILLIAMs, a citizen of the United States of America, residing at Elk City, in the county of Beckham and State of Oklahoma, have invented certain new and useful Improvements .in Cotton-Cleaners, of which the following is a specification.

This invention relates to cotton cleaners and more particularly to an apparatus or device adapted to clean cotton as it is obtained from the field before being ginned.

One of the objects of the present invention is to provide a simple and practical cot.- ton cleaner which will be inexpensive to manufacture and operate.

A further object is to provide a cotton cleaner which will be reliable and efficient in use and operation and adapted to thoroughly clean the cotton as it is obtained from the field.

Other objects will be in part obvious from the annexed drawings and in part indicated in connection therewith by the following analysis of this invention.

This invention accordingly consists in the several features of construction, combination of parts and in the unique relations of the members and in the relative proportioning and disposition thereof; all as more completely outlined herein.

To enable others skilled in the art so fully to comprehend the underlying features thereof that they may embody the same by the numerous modifications in structure and relation contemplated by this invention, drawings depicting a preferred form have been annexed as a part of this disclosure, and in such drawings, like characters of reference denote corres onding parts throughout all the views, 0 which Figure 1 is a longitudinal sectionalview of such parts of the complete apparatus as are necessary to understand the invention; and Fig. 2 is a transverse sectional view of the same apparatus.

Referring now to the drawings in detail and more particularly to Fig. 1, 5 denotes a casing mounted on a suitable framework 6 of any desired character either portable or stationary and is provided'with an inlet 7 having a turnable connection 8 with the casing whereby it may be directed to receive the uncleaned cotton from any direction.

Pneumatic means (not shown) of any desired type' are preferably connected with Specification of Letters Patent.

Serial No. 111,501.

this inlet by means of a flexible tube to force the cotton down into the casing where it is engaged by a plurality of beaters 9 mounted upon suitable shafts 10 extending transversely of the casing 5. Adjacent these beaters are a pair of picker rolls 11 also mounted on transversely disposed shafts. All of'these shafts. are connected :by either gearing or belting on the outside of the casing whereby they rotate in the same clockwise direction as indicated by the arrows on the drawing. Beneath the boaters and. picker rolls is positioned an undulating screen 12 over which the cotton fibers are forced by the rotation of the. beaters andpicker rolls. At the lower opposite end of the casing from the inlet is a discharge tube 13 provided with a rotatable trap member 14 through which the cotton is passed with a minimum passage of air. The arms of the trap are provided with flexible tips 15 coacting with the interior surfaces of the casing 13. The cotton is discharged at the lower end into any suitable receptacle. The lower part of the casing 5 is provided with inclined Walls 16 at the bottom of which is provided a spiral or any suitable form of conveyer 17 adapted to discharge the dirt and foreign substance extracted from the cotton out through a suitable valve'18 at the side of the casing.

As shown more clearly in Fig. 2, both sides of the casing 5 are provided with discharge air outlets 20 at right angles to the flow of the cotton which lead to ducts or passageways 21 extending to a main outlet 22 at the rear of the machine, Fig. 1, where the air is allowed to escape through a suitable opening to a tube, not shown, for directing the air to the place desired. By providing these air'outlets 20 at opposite sides of the casing a more even distribution of the air currents is obtained so that the air passes through .the entire film of cotton fibers supply of cotton such as a hopper, whereby the cotton fibers are pneumatically forced into the casing 5 and engaged by the beaters and picker rolls and carried along evenly over the screen 12. The air being forced into the casing with the cotton under considerable pressure will thoroughly clean the fibers removing all dirt and foreign matter as far as possible. The cotton is carried along in athin film and passes through the trap valve 14 into a suitable receptacle, as desired. The spiral conveyor 17 is of course connected by gearing or belting in any desired manner with the main source of power in order to remove the dust and dirt extracted from the cotton as the same falls into the bottom of the hopper-like casing.

The invention is simple and practical in construction and is particularly designed to thoroughly and efficiently clean the cotton.

Without further analysis, the foregoing will so fully reveal the gist of this invention that others can by applying current knowledge readily'adaptit for various applications without omitting certain features that, from the standpoint of the prior art, fairly constitute essential characteristics of the generic or specific aspects of this invention, and therefore such adaptations should Copies of this patent maybe obtained. for five cents each, by addressing the Commissioner of Patents,

casing, a plurality of beater rolls adjacent the inlet and above said screen, a plurality of picker rolls near the opposite end of the casing and above said screen and a substan tially air-tight trap beyond'the picker rolls, said casing being provided with air ducts along its sides below the pickers and heaters whereby the air used in feeding the material to be cleaned passes uniformly through the Y v screens and horizontally with respect thereto out through said air ducts, and a conveyer in the bottom of said hopper having a trap outlet adapted to discharge the refuse extracted from the material to'be cleaned.

In testimony whereof I affiX my signature in the presence of two witnesses.

SAMUEL WILLIAMS.
