' 55 charger 24 into the pipe 13 14.

In the event that the cotton being transferred through the tubeA'to the gin-house requires nocleaning the valves or deflectors 8 9 may be lowered to close the openings 6 7,

so that the cotton will be drawn` directly* through the conduit A. In the event, however, that the cotton, as is generallythe ease,l contains foreign substances or material which it is desirable to eliminate the valves or deio flee-tors 8 9 ma be raised to the positions indicated by fulllines in Fig. 1 to direct the cotton into the pipe 10. The feed and discharge devices 16 24 are suitably connected with a driving power, towhich the pulley 28 is .also belted, and the latter is caused to rotate and turn the reel described, which `carries -the vanes 38 in the direction which causes the lower ends of the vanes to move in advance of their upper ends. The suction- 2o fanat the gin-house creates a strong current l of air through the pipes or by-passage 10 13 14. The cotton drawn into the -pipe 10 moves to the vacuum-box or chamber 11 and strikes against the screen 12, dropping there- 2 5 from through the pipe 15 and is delivered by the 4feeder 16 to the interior of the casing. In practice the reel is rotated rapidly to have a peripheral travel of, say, iive thousand feet per minute. As the cotton-falls through the lmore feet of travel around the wall the cot- ,ton is subjected in a comparatively thin layer to a strong current of air through it, which blows out the dirt and leaf trash', leaving the 'cotton in a `fine fluffy condition.

The devices 16 and 24 may rotate at com: paratively slow speed and operate, respecltively, to feed the cotton into and discharge it from the cleaning-chamber. While performing these functions they maintain the pipes 15 and 23 closed against the passage of air-currents. Thus practically no material portion ofthe cotton-conveying current set up in the pneumatic tube A .passes through the cleaning-chamber to weaken the current. The screened top 20 operates as a guard to prevent any cotton from being thrown out of the chamber by the action of the reel. forceof air for cleaning the cotton is generated by the reel alone, the blades 3S of which yare set at an angle, -and this air which is -drawn in through the screened top 20 is'discharged outwardly through the cotton spread along the perforate or screen wall 17. As the wall 17 tapers in the, downward direction, .material forced through its perforations drops therefrom readily.

The retarding of the downward movement of the cotton b y gravity through the cleaner 3o opening 19 it is forced by the reel and the strong air-current generated thereby against the perforate wall 17, around the inner surface of which it tends to spread in a thin sheet or layer. The reel in its rotation draws j 3 5 in air through the top screen 20 and forces it through the screen-wall 17 ,whereby the centrifugal current as it passes through the coto yton blowsout through the wallany dust, sand, or the like, as well as small particles of .4o dry leaves that maybe mixed with the cotton. 4The blades through their engagement with the cotton sli'de or roll the latter around and around against the wall 17, and the cotton descends by gravity to the base 2l. The

4 5 object more especially of causing the blades to extend spirally is to retard the descent of the cotton. Thus disposed the blades tend to produce an upward as well as outward blast of air and to beat up the cotton, thereby 5o causing it to descend slowly and be carried around a number of times to prolong its subjection to the cleansing blast. When the cotton descends to thc base 21, it is moved to and the extent therefore to which it is suhjected to theclcaning blast depends `upon 'the spiral pitch of the blades 3S, which may4 be regulated according to requirements by raising and lowering the collars 31 32 and adjusting the disk 33, as before explained.

I'Vhat I claim as new, and desire to secure by Letters Patent, is-

1. In a pneumatically-operating cottoncleaning apparatus, the combination of a vertical chamber having an air-inlet, a cylindrical screen forming the surrounding wall of the. chamber, means for creating an air-blast in the chamber and for directing it outwardly through said wall, means for feeding the cotton into the upper part of the chamber, whereby it descends by gravity through the chamber across the path of the blast, an outlet for the cotton in the lower part of the chamber, and cotton-retarding means in the chamber for regulating the speed of descent of the cotton through the chamber.

2. In a pneumatically-operating cotton- 'cleaning apparatustthe combination. of a verthe opening 22 to be discharged by the dis- From thence it is sucked upward through the opening 7 to the conduit A and drawn to the gin-house.

The actionupon the cotton in the cleaning operation is not at all severe, as it is opened oo up by the round smooth ends of the teeth 39, j which do not injure .the ber, and after being opened up the cotton isl kept in'sliding or l rolling contact with the wall 17, being carl yried around, in practice, preferably ten or o5 more times. Thus during one hundred or tical chamber having an air-inlet, a screen forming the surrounding wall ol the chamber a. blast-creating reel in thechamber operating to force the blast outwardly through said wall, a feed-opening for the cotton in the upper part of the chamber, an outlet for the cotton in the lower part of the chamber, and means upon the reel for regulating the speed of movement of the cotton through the chamber. ,i

. 3. In a pneumatically-operating cottoncleaning apparatus, the f zenibuation of a The l chamber having its surrounding Wall formed of a screen and provided with en air-inlet, an inlet for cotton at one end and an outlet therefor at its opposite end, a reel in the chamber provide l wi th a plurality of blades having serrated edges adjacent to said Wall, and means l'or rotating the reel.

4. ln a pnenmatically-operating eottoncleaning appa atus, the combination olga chamber having its surrounding wall formed of a screen and provided with an air-inlet, an inletA l'or cotton at one end and au outlet lherel'or at its opposite end, a reel in the chamber provided with a 'plurality of blades having corrugated edges forming roundedged teeth adjacent to said wall, and means ior rotating the reel.

ln a pneumatically-operating cottoneleaning apparatus, the Combination of a chamber having vits surrounding wall formed' of a screen and provided with an air-inlet, an inlet 'for cotton at one end and an outlet tlicrefor at its opposite end, a. reel inthe chamber provided with a plurality of spirally arranged blades adjacent to said wall, means for adjusting the spiral pitch of the said blades, and means for rotating the reel.

l6. In a Ainennratically-operating cottoncleaning apparatus,the combination with a eotton-conveying pneumatic tube, of a bye passage communicating at opposite ends with said tube, a screen in said. liv-passage, a

Vertical chamber having ils surrounding wall formed of a screen eoininunienting at its upper end with said b if-passagein advance olA tho screen. therein an outlet in the lower end ol' said chamber coninnniieating with said h3'-V passage, a cotton-discharger in said outlet, an air-inlet in the upper part ol' said chamber, a reel in the chamber provided with a plnralit)v of spirally-arrangcd blades adjacent to said wall7 and means for rotating ther-eet 7. ln a pneuniatieallyaip'erating cottonL cleaning apparatus, the combination with a cotton-conveying pnenmatio tube., of a bypassage communicating at opposite ends With said tube, means for opening and closing said liv-passage, a sereen in. the by-passage, a vertical chamber having it; surrounding wall formed of a screen. and provided With an air-inlet, a conduit communicating with the luy-passage in advance of the screen therein and discharging into the upper end of said chamber, a rotary feeder in said conduit, an outlet for Cotton at the lower end oi' said chamber leadingto said bypassage, a; reel in the chamberprovided with a pluralit)r of spirally-arranged blades adjacent to said Wall, and ineens for rotating the reel.
