Abstract: A grain cleaning attachment is disclosed for a grain auger. The attachment includes a cylindrical vibrating portion to surround the auger flighting after removal of a portion of the auger tube. The vibrating member is sized to provide a clearance between the walls of the member and the auger flighting to permit vibratory displacement of the member. Rubber sleeves connect the vibrating member ends to free ends of the auger tube. A vibration motor is carried by the vibrating member to affect vibration of the member. A tube support member is provided comprising a pair of rigid sleeves rigidly connected to the auger tube on both a downstream and upstream side of the vibrating member. Rigid braces connect the sleeves in axial alignment. A downstream sleeve has an opening to find therethrough in communication with an interior of the tube with a blower carried on the sleeve having an intake in communication with the opening.

Abstract: Apparatus for cleaning pleated paper and other hollow cylindrical filters by centrifugal force combined with reverse air flow. A housing carrying a rotatable platform supports one end of the filter, and a closure unit for a housing aperture centers the filter by contact with the other end and frictionally rotates it through the contacting surface. Filter rotation is concurrent with removal of air from the housing around the filter, to be replaced by air drawn through the filter as a whole through the centering and driving components of the closure unit. Means for facilitating the emptying of collected material from the housing is shown, as is means for adapting the structure for use as a simple vacuum cleaner.
