Abstract: A cotton gin lint cleaner includes a rotating saw cylinder. A continuous layer of lint cotton is fed along the cylinder by feed works. The layer is seated in and moved downstream by saw teeth on the cylinder. Foreign matter is loosened from the layer as it is moved beneath grid bars spaced along the cylinder surface. A combing bar downstream of the grid bars with teeth opposed and proximate the saw teeth further cleans the cotton layer.

Abstract: An emergency actuator bar extends across an opening in the housing of a lint cleaner in a cotton gin. Actuator arms which hold the bar also normally hold a trip plate in the run position. However, a workman striking the emergency bar will remove a sear on one of the actuator arms from the trip plate to permit a spring to snap the trip plate into a stop position. When the trip plate moves to the stop position, it disconnects electrical power to a motor driving the machine. The trip plate movement also applies a brake which stops the machine.

Abstract: Cotton in an extractor-feeder is passed through three scrubber cylinders. The first two having grid bars of a regular 1/4 or 5/16 inch spacing and the third having grid bars at about twice the regular, or 1/2 inch spacings. Any locks of seed cotton in the trash from the third scrub cylinder are reclaimed by reclamation saw which also reclaims any cotton slung off by a main saw cylinder. Also dust is removed by a suction connected into the housing.

Abstract: An air filter having a counter rotating drum, i.e., the rotation of the drum is opposite the tangential intake of air. The intake air has about 1 lb. of rock wool fibers per 10.sup.7 cu. ft. of air sometimes at about 100% relative humidity. The fibers are doffed from the drum by suction nozzle which are adjacent to the drum at the bottom of the filter housing. The drum screen is cleaned by periodically jetting hot dry air at 120 psig through the screen into the suction nozzles.

Abstract: A trash by-pass panel is pivoted to the reclamation chute wall in a cotton gin burr and stick machine such that it may be opened to allow heavier trash to be excluded from further processing, thereby increasing the efficiency of the cotton cleaning.

Abstract: The bottom of a lint feeder housing is manufactured such that the high speed belt which it houses is quickly and easily changed. The bottom of the housing is lowered after loosening the four hinged thumb bolts which secure the bottom to the housing. After the bottom is lowered, the axles which support conveyor rollers are lowered a little on one side. The worn belt is removed and a new belt is slipped between the axles and the frame of the housing then over the rollers. Once the new belt is in place, the axles are raised and the bearing housings are fixed to the feed housing. Finally, the bottom of the housing is raised and secured in place.
