Specification of Letters Patent.

Patented Dec. 12, 19115.

Application iled November 26, 1915. Serial No. 63,1161.

To all whom t may concern:

Be it known that I, EUsTIcEE. DICKnRsoN, a citizen of the United States, residing at Fort Worth, in the county of |Iarrant and State of rI`exas, have invented certain new and useful Improvements in Cotton-Clean ers, of which the following is a specification.

My invention has relation to an improvement in cotton cleaners of the type or class illustrated and claimed in Letters Patent No. 1,149,253 granted to me on August 10, 1915.

In the cotton Cleaner described and claimed in said patent, the cotton is forced under pressure of air through a boll breaker and then through a cylindrical cleaning chamber and the cotton is finally forced into a pipe or flue at the rear of the chamber in which pipe or liue means are provided for separating the air from the cotton.

It has been found in practice that th pressure and volume of air carrying the cot ton through the cleaning chamber and into the flue at the rear of said chamber has been greatly in excess of what was required. The cotton after leaving the flue or pipe was blown all over the bin or receptacle like a miniature snow storm.

It is the main object of this present invention to discharge the cotton properly separated from air from the side of the cleaning chamber and to guide the same into the belt or conveyer for feeding the cotton to the gins.

In the carrying out of my invention, at or near the discharge end of the cleaning chamber I enlarge the wall of the chamber to form an off-set or box-like compartment, serving, when properly fitted and arranged, on one hand as an air separator and on the other hand as a chute or guide for the cotton separated from air onto an endless or traveling conveyer or belt, which belt conducts and discharges or feeds said cotton to the gins. The box or offset compartment projects radially or rather at right angles to the shaft of the cotton cleaner.

rlhe compartment is separated at one portion from the interior of the cleaner by a partition, partly perforated and partly imperforate, so that that part of the compartment acts as an air separator, the compartment being connected by pipe or flue with the external air. Y

Alt the base of the compartment is arranged an endless belt or conveyer to receive the cotton, and the wall of the cleaner 1s continued tangentially to form with the partition of the air separating chamber, a chute or guide to conduct the cotton from the interior of the cleaner to said endless belt or conveyer.

rIhe nature and objects of my invention will be more fully understood from the following description taken in connection with the accompanying drawings forming part hereof, in which- Figure 1, is a side elevational view', partly sectioned, of a cotton cleaner embodying the main features of my invention, and Fig, 2, is a vertical sectional view taken on line a-a of Fig. 1.

Referring to the drawings, 1 represents the exterior wall of the cotton cleaning chamber' and v2 represents the screen like or perforate wall which incloses the paddle or stirring blades 3 and within which walls the cotton is forced under pressure of air. At the entrance end to the cleaner is located the boll breaking mechanism inclosed in the case or wall f1 and at the exit end, the cleaning chamber is walled up or sealed by an imperforate'head or Wall 5. The shaft 6 which carries the blades 3 traverses `this head 5 and has its bearing 6l located outside of said head 5 but supported thereon and thereby.

'Ihe wall 1 is cylindrical until it reaches the exit end of the apparatus. At or near this point a box or compartment 7 is built out from cylindric wall 1 and extends with a discharge or outlet 8 below the cleaning chamber. Immediately beneath this outlet 8 from box 7 is located the endless belt or conveyer 9 upon which the cotton is received and by means of which the cotton is conveyed to the gins.

The screen wall 2 of the cleaner, at the point where the box or compartment 7 projects, is flared out tangentially into a perforate portion 10 and an imperforate portion 11 the two constituting a partition separating the box or compartment 7 into an upper and a lower chamber. The upper chamber 12 is an air separating chamber since it is in open communication through perforate portion 10 of the partition with the interior of the cotton cleaning chamber and the chamber 12 is also in open communication with the external air through the upper flue or pipe 13 and the lower flue or pipe 14.

'Ihe lower half of box 7 is completed by a wall 15 extending substantially tangentially from the perforated or screen wall 2 esy of the'cleaner to the discharge or outlet .8

Yfrom the boX 7. The partition 10,11 and therWall 15 form an outlet or chute directly from the interior of the'cleaning chamber to Y .the outlet 8 and the'belt conveyer 9.

In'the operation ofthe cleaner, the cotton under air pressure traverses the cleaner until it reaches the boX or compartment 7. Here .fthe air is separated from the cotton and the Y ie cotton directed to the eXitS from boX 7 onto the Vbelt Vdistributer 9.

lI-Iaving thus described the nature and objects of'my invention, VWhat l claim as neW v lment into two chambers, said partition consisting of the screen wall and an imperforate extension proj ectlng tangentially from the VCopiesof this patent may be Vobtained for screen Wall of the cleaning chamber, an outlet from said compartment communicating With the interior of the cleaner chamber through the second chamber oi said conipartment, and pipes leading from the {irst chamber of said compartment to constitute said chamber an air releasing chamber for the cleaner.

2. In a cotton cleaner comprisinga cylindrical chamber having a screen wall through Which chamber air and cotton under pressure are forced, an imperforate Wall forming the end of said chamber, a boxlike outlet projecting from the side of the cylinder adjacent to the end, and a partition formed of the screen wall and an imperferate extension, said partition projecting tangentially from said screen wall, and di viding the box-like outlet into two chambers whereof one is the air release and the other a discharge for the cotton.

In testimony whereof I have signed my name to thisspecitication.

EUSTICE E. DICKERSON.
