IMPROVEMENT IN COTTON-CLEANING MACHINES.

Specification forming part of Letters Patent No. 30,850, dated December 1l, 1860.

To aZZ whom it may concern:

Be it known that I, BENJAMIN JneinvrAN, of Louisville, in the county of Jefferson and State of Kentucky, have invented a new and Improved Cotton Cleaning and Condensing VMachine; and I do hereby declare that the following is a full, clear, and exact description of the same, reference being had to the annexed drawings, making a part of this specification, in which- Figure 1 is a side elevation of my invention. Fig. 2 is a plan or top view of the same, with a .portion of the top of -the box or case removed or broken away. Fig. :3 is aside sectional view of the saine, taken in the line x x, Fig. 2.

Similar letters of reference indicate corresponding parts in the several figures.

This invention relates to a machine designed y to be attached to or connected with the iiue of a cot'ton-'gin,for thepurpose of cleansing the cotton or separating the dirt from it' and condensing it, so as to facilitate the baling operation.

The invention not only facilitates the opera'- tion of baling, but also causes the bales to be more uniform and compact than by the usual baling process, and also obviates the employment or use of a lint-room -to receive the ginned cotton, and in which lint-room one or more hands are generally employed, to their great and often fatal injury, caused by the inhaling of the dust and fine particles of cotton with which the air within the lint-room is filled.

The invention consists in the employment or use of revolving screens in connection with a dust-chamber and with a stationary screen and condensing-rollers,arranged substantially as hereinafter fully shown and described.

f To enable those skilled in the art to fully understand and construct my invention, Iwill proceed to describe it.

A represents a case or box, in which two revolving cylindrical wire screens, B B, are placed, one over the other in the same axial plane, the peripheries of the screens being nearly or quite in contact. The heads a of the screens at one end have openings I) made inthem, said openings forming a communication between the interior of the screens and a dustchamber, C, adjoining the ease or box A. (See Figs. 2 and 3.)

At the outer or front parts of the screens B B there are aprons D E, one to each screen. These aprons are quite near the screens, and the upper one, D, extends nearly half around the upper screen B, while the lower one, E, extends about one-quarter around the lower screen, asl shown clearly in Fig. 3.

F F are two rollers, placed one over the other in the same axial plane, and having smooth or fluted surfaces. The rollers F are placed quite near the periphery of the lower screen B, and their bite is on a horizontal line with the upper end of the apron E, as shown clearly in Fig. 3.- G is the box or passage,whieh forms a communication between the case or box A and the -flue of the ginto which the invention is ap-4 plied.

H is a screen which is placed horizontally in said box or passage G, and has a sink or box, I, beneath it. The face or upper surface of the screen H has slats c secured on it at suitable distances apart, asv shown in Fig. 3.

The shafts of the screens B B extend through one side of the box or case A, and are connected by gears J, into the upper one of which a pinion, K, on the driving-shaft L meshes. lThe lower gear, J, meshes into a pinion, Il', which is engaged with the lower of two gears, M M, which connect the shafts of the rollers F F.

The operation isas follows: The drivingshaft L is rotated by any convenient power, and the cotton passes from the gin over the stationary screen H in the box G, the cotton being propelled by the strong current of air generated by the rotation of the brush. The box or sink I receives all the dirt and trash that by its gravity will fall through the screen H, while the cotton is blown, over it. The cotton passes into the case or box A freed from the coarser and heavier particles of dirt, and is brought in contact with the revolving screens B B, through which the light dirt and dust pass into the dust-chamber O, as indicated by the black arrows. Ihe cotton is then drawn between the screens B B, the lower end of .apron D stripping the cotton from the upper screen, and causingit to follow the periphery of the lower screen until it comes in contact with the lower apron, E, the upper end of thelatter deflecting the cotton off from the lower employed as may be required, andv the bat or B B and aprons D E with the box A, dustvsheet may be directly conveyed by an endless Chamber C, sereen H, and eompressingrollapron to the press for baling, or it; may be ers F F, in the manner and for the purposes I folded for a future hailing operation. herein shown und described.

Having thus fully described my invention, BEN. JAOKMAN. what I elaini as new7 and desire to secure by VVibnesses: Letters Patent, is- Jos. CLEMENT,

The arrangement of the two rotary screens l l). A. N. BRADLEY.
