Abstract

The present disclosure relates to a spark plug cleaner and a method of operating the cleaner. The spark plug cleaner includes a closed container adapted to receive and hold a spark plug in a horizontal position with its electrode inside the closed container. A motor driven multi-directional rotatable impeller, having a vertical shaft extending through the top wall of the container, is mounted within the container with the multi-directional rotatable impeller having an axial inlet facing downwardly inside the container. The container is provided with a horizontally extended duct between the lower end of the spark plug holder and the downwardly open inlet of the multi-directional rotatable impeller to permit the impeller to project the particulate against the spark plug and to continuously recirculate the particulate through the multi-directional rotatable impeller during operation.

Dependent claims

A spark plug cleaner including in combination,

a closed hollow housing comprising a lower impeller housing and an upper motor housing, each of said housings having interfitting margins whereby said housings may be held frictionally and closely fitting relation to provide a closed but separable hollow housing,
a drive means mounted in said upper motor housing and having a vertical drive shaft extending downwardly into said lower impeller housing,
a multi-directional impeller mounted in said lower impeller housing and operatively connected to said vertical drive shaft, said impeller having an axial inlet opening downwardly therefrom and a plurality of vanes about the periphery thereof,
elastic spark plug holder means mounted in the side wall of said lower impeller housing, said spark plug holder means adapted to receive and hold a spark plug in a horizontal position and in register with respect to the outer periphery of said impeller, and
flow directing baffle means positioned between said impeller and the base of said lower impeller housing, such that upon the rotation of said multi-directional impeller by said drive means particulate is discharged radially outwardly against said mounted spark plug and said baffle means provides a path for predeterminely guiding the flow of air and spent particulate discharged by said impeller towards said axial inlet opening of said multi-directional impeller and into the eye of said rotating impeller for subsequent discharging of the flow of air and particulate by said impeller against the spark plug until the cleaning operation is completed.

A spark plug cleaner including the combination,

a closed impeller housing having a side wall and a bottom wall,
a multi-directional impeller mounted in said impeller housing and operatively connected by a vertical drive shaft to a drive source, said impeller having an axial inlet opening downwardly therefrom and a plurality of vanes about the periphery thereof,
elastic spark plug holder means mounted in said side wall of said impeller housing, said spark plug holder means adapted to receive and hold at least one spark plug in a horizontal position and in register with respect to the outer periphery of said impeller, and
a flow directing baffle means positioned between said impeller and the base of said impeller housing, such that upon the rotation of said multi-directional impeller, said particulate is discharged radially outwardly against at least one of said mounted spark plugs and said baffle means provides a path for predeterminely guiding the flow of air and spent particulate discharged by said impeller towards said axial inlet opening of said impeller for subsequent discharging of air and particulate by said impeller against at least one of said spark plugs until the cleaning operation is completed.
