` `lVlACIIINE' `FOR CLEANING COTTON.

specification or Letters Patent No. 10,762, dated April 11, 18.54. y

To aZZ whom t may concern Be it known that I, CHARLES LEAVITT, of the city of Quincy, county of Adams, and State of Illinois, have invented a new and useful Machine for Dusting Cotton Previous to Ginning the Same; and I do hereby declare that the following is a full, clear, and exact description of the construction and operation of the Same, reference being had to the annexed drawing, making a part of this specification, in which- Figure l is'a vertical section, and Fig. 2 the frame with pulleys and belts not shown in Fig. l.

The nature of my invention lconsists iii a method of cleaning cotton and freeing it from motes, dust, and impurities, previous to ginning it, the latter operation having the tendency to incorporate the dust and impurities so intimately with the fiber that it is difficult to obtain aclean article. By preceding the ginning operation by my method of cleaning the cotton, while attached to the seed the article is made to present a much better appearance and the fiber being less bruised it is more marketable, and of superior quality.

I make a frame consisting of four pieces (a). The long sides of this frame are closed in by boards (Z9) sufficiently high to embrace the circular concave screen (c) and sufliciently low to touch the ground. Circular openings are made ineach side (ZJ) for the purpose of admitting air to the wind wheel (f) and Suliiciently large to give facilit-y of access to the heads of the revolving screen (g). The concave screen (c) is made of open wire work fastened to annular heads (71,) which are secured to the sides (b). The concave is supported on the outside by ribs fastened to the heads t) and these Aribs are furnished with teeth project-ing inwardly through the wire work, and at sulficiently wide distances apart to pass between corresponding teeth `on similar` ribs on the inside of the revolving screen (g) which project outwardly through the wire work thereof. fIhe concave screen (c) has a suitable opening at (j) for the admission of the cotton above the hopper bottom (7c) and for its abduction below the hopper by the revolving stripper (Z) which lies athwart the same end of the frame. The revolving screen (g) is attached to a head (m) which' is driven by the power used tooperate the machine, thishead having a spindle running in a boX on the frame (a) the driving pulley`(y) being tiXed to this spindle. The other head of the revolving screenhas a hollow journal (a) running in a box (o) on the opposite side of the frame (a.) through which the shaft (e) of the wind wheel (f) passes having a driving pulley (n) thereon the vother end of the shaft (e) runs in a socket in the center of the head (m). The belting is arranged with regard to suitable velocities for the dilferent parts by means of the standards (g), in bo-Xes on the top of which runs the shaft (r) carrying on each end, pulleys; one (s) of small diameter to cooperate with the pulley (y) on the spindle and drive the wind wheel by means of the `large pulley (t) on the other end of the shaft (r). On the hopper side of the standards (g) another shaft (u) is hung in boxes and carries on the same side of the machine with the large pulley (t) a Small pulley (fv) which enables the same belt (fw) to operate the wind wheel and the cylindrical stripper (Z) by making an inverted V lap of the belt, which thus moves four pulleys of suitable diameters for the proper velocities to be given to the wind wheel (f) and the stripper (Z) both of which are driven at high velocities, while the revolv ing screen is driven at comparatively low speed so as to carry the cotton slowly, with;

out breaking t-he seed or t-he ber, and give the wind wheel which runs within the screen the greatest possible chance to blow out, the motes, dust, and other impurities as the teeth on tlie ribs of the revolving screen gently loosen the fibers of the cotton, allowing the seeds to pass to be afterward eX- tracted by the gin. The top of the machine on a level with the side, and the hopper end of the concave are covered in. The cylindrical stripper is also covered in, and a hopper is thus formed for feeding the machine, the ordinary rake is used and fixed to the frame for the purpose of clearing the stripper of the cotton as it gathers from the screen. The machine may be attached to any of the common forms of cotton gins, so that the cotton may pass from it at once to the gin. y

What I claim as my invention and desire to secure by LettersPatent, is-

method of arranging the several parts involvedin extracting the motes, dust, and

other impurities from cotton previous to and preparatory for ginning the same, substantially in the manner and for the purpose described; t-hat is combining a Wire screen concave with a revolving Wire screen cylinder or their equivalents, and a Wind Wheel or fan; revolving Within the cylinder, both cylinder and concave being armed With teeth set in ribs so distant apart with regard to the teeth, as to permit the cotton seed to pass, While the fiber alone is loosened, the revolving screen running slovvly in comparison with the Wind Wheel which is driven lat great velocity, thereby adapting the mamy hand this seventeenth day of June 1853 the same being a true description of my invention.
