ABSTRACT:
The present invention provides a compact, completely enclosed motor driven spark plug cleaner. It is preferably battery driven and is adapted to be held in the hand of the user. The invention provides a device for projecting granular abrasive against the electrodes and the insulation of a spark plug to clean them of carbon deposit. Safety features prevent projection of the abrasive particles into the face and particularly the eyes of the operator. Spark plugs of various sizes and screw threads may be treated without requiring any structural adjustments by the operator. The blast of abrasive particles is directed against the electrodes or "points" of the spark plug at an angle to the longitudinal axis of the plug, and the plug can be rotated and wobbled in its mount. This provides a novel and advantageous mode of operation and constitutes a novel method of cleaning a spark plug.
