Abstract: A delinter apparatus for seed cotton includes a jack screw displacement system for a gratefall which opens the apparatus for removal of a saw cylinder while urging a plurality of belt tensioning idlers into a relaxed position such that the drive belt for the saw cylinder can be removed in a simplified and more efficient manner. The apparatus also has improved flow characteristics due to improvements in the lint feeder design as well as the transition designs from the feeder to the float chamber and saw interface.

Abstract: A multistage lint cleaning apparatus includes plural series arranged rotary drum beaters in a first cleaning stage, each beater having a separating screen disposed adjacent thereto for separating particulate material and fine lint from longer fiber lint. Each screen is configured as a drawer supported within an enclosure for insertion and removal, at will. Clean lint discharged from the first cleaning stage passes through an air gap and into a duct connected to an aspirating nozzle for further separation of particulate material. A linear belt conveyor receives particulate material and fine lint from the first cleaning stage for discharge to a second cleaning stage also comprising a series of rotary drum beaters. Separating screens associated with each beater of the second cleaning stage are also configured to be inserted in and removed from an enclosure, at will. A third cleaning stage comprises a vibrating screen.

Abstract: Cottonseed processing system includes a huller/separator combination. The huller assembly has a pair of counter-rotating, toothed rollers for shearing the seed hulls, with the shearing surfaces provided by removable segmented plates. The separator assembly is provided by a vertically disposed, angularly stepped, air duct with upwardly directed air flow separating the seed hulls from the seed meat products. A paddle wheel feeder assembly functions as an air lock between the huller assembly housing and the air duct.

Abstract: Cottonseed processing machinery has an automatic variable speed feeder. Cottonseed flows through a chute into a hopper and out of the hopper onto a gratefall adjacent turning saw blades. A curved section coextensive with the gratefall overlies the gratefall and urges the cottonseed toward the gratefall and saw blades. The sensing means of a switch detects movement of a weighted arm urging the curved section toward the gratefall. A float shaft is rotated between the gratefall and the curved section in the cottonseed roll. Pulleys drive one part of an electric clutch from the clutch shaft. The other part of the electric clutch when energized connected the first part to the speed reducer which in turn drives the feed roll shaft.
