Abstract
The sparkplug cleaner of the present invention provides a closed container, comprising a cylindrical barrel member open at its upper end. Its upper open end is adapted to be closed by a cover member, upon the center of which is mounted an electric motor having a vertical shaft extending down through the cover member. The said shaft on its lower end, inside the container, carries a closed impeller rotatable in a horizontal plane to throw the particulate abrasive out tangentially. Inside the cup-shaped barrel member, and below the impeller, are mounted guiding vanes for guiding the return flow of airborne abrasive particles carried upwardly in a swirling airflow circulation created by the rotating impeller.
