Smith, Jr, J M

An exhaust filter for controlling emissions in a discharge gas stream is described comprising: an outer housing; a first exhaust gas passageway comprising a cylindrical pipe received within the outer housing. The pipe is provided with openings formed in an outer surface of the pipe and having a first end and a second end projecting from the housing. The cylindrical pipe receives the discharge gas stream and defines a first fluid pathway through the outer housing for the gas stream; a second exhaust passageway formed within the outer housing, in fluid communication with the first passageway and defining a second fluid pathway for receiving a selected portion of the discharge gas stream passing through the first fluid pathway; a filter means placed within and filtering the selected portion of the discharge gas stream passing through the second fluid pathway; and diverting means comprising at least one baffle spinner rotatably mounted within the cylindrical pipe adjacent one of the openings formed therein, progressively diverting the discharge gas stream from the first fluid pathway to the second fluid pathway and progressively diverting the filtered discharge gas stream from the second fluid pathway to the first fluid pathway.
