Abstract

A novel cleaning assembly for a dryer feed chute comprises a shaft, a housing in which said shaft is rotatably mounted, a carriage for carrying the housing and the shaft member, drive mechanism for rotating the shaft, and an oscillating chain for moving the housing and hence the shaft in the longitudinal direction. The oscillating mechanism includes control structure for providing longitudinal movement of the housing and the shaft from a first position to a second position and thereafter back to the first position to complete a cycle.
