On account of the weevil's habit of becoming quiet when disturbed, 

 it has been found that there is little danger of individuals that have 

 been fed into the spiral conveyor crawling out before the trash is 

 deposited. This slight danger may be partially obviated by simply 

 covering the conveyor box between the gin stands, so that the only 

 openings into it will be within the screening chamber, and the only 

 outlet will be at the spout leading to the trash receptacle. 



Apron cleaner feeder. — This cleaner feeder is designed for use with 

 the basket system of feeding at small ginneries, and also with the dis- 

 tributor-belt system. All the trash, including the weevils, which falls 

 from the revolving apron drops directly upon a spiral conveyor and 

 becomes mixed with the trash removed by the picker roller, beating 

 the seed cotton against the screen beneath it. Both weevils and trash 

 are carried through a pipe at the end of each gin and discharged into 

 the seed conveyor, or a box placed below or upon the floor. In these 

 cleaners the screw conveyor is the length of one gin stand only, and is 

 not connected through a full battery of gins, as is the case with the 

 ordinary cleaner feeder previously described. In order to make it 

 accomplish the same result as in the upright cleaner feeder, it would 

 be necessary to convey the trash through spouts from each separate 

 gin, leading, at the rear of the battery of gins, into a spiral screw con- 

 veyor, which would carry the trash to any point desired. This spiral 

 conveyor should discharge between compression rollers, or other 

 devices which could be easily provided, whereby all insects reaching 

 them would be destroyed. This method of destruction will be detailed 

 more fullj'^ in the recommendations. 



Special cleaner feeders. — In addition to the ordinary and apron cleaner 

 feeders, which have been described, special forms are now manufac- 

 tured by some companies, and there seems to be considerable activity 

 in improvements in this line of ginning machinery. In some cases 

 these devices combine elevating, cleaning, distributing, hulling, and 

 feeding operations. In the ordinary cleaner feeders the seed cotton 

 is drawn by the suction of the fan and separated from the current of 

 air by a screen. The cotton usually strikes the screen in a more or 

 less compact body, so that comparatively few weevils are driven 

 through this screen. In the improved systems, however, the seed 

 cotton falls directly upon a revolving beater, which drives it against 

 the screen and separates the locks thoroughly. In some cases the 

 cotton is then passed on to another beater, revolving against a similar 

 screen, thus giving it two thorough workings. As the full force of 

 the air passes through these screens, all boll weevils and trash, sepa- 

 rated by the combined beating and screening operations, are passed 

 through the fan and thereby destroyed. In one form of feeder, in 

 addition to the two beaters, a picker roller is used, and below that a
