Abstract: A cotton lint cleaner having a number of new and unique features. The lint cleaner uses a common air stream laden with cotton to be cleaned through a moving screen and then through feed rollers to a cylindrical saw, where a centrifugal air flow doffing impeller doffs the cleaned cotton from said saw, for discharge from the device. Special spring biased feed bars are also a part of this invention. Additional features include special grid bars, special settling and collection chambers, guide vane structure, a rotating paddle wheel vacuum lock, an adjustable vacuum valve control, and filtering and discharging of the exhaust air flow through a cover over the operating drive for the over-all machine in order to exclude contamination from the outside air of said drive components. Special tension mountings for the grid bars are also disclosed.
