Abstract
In combination with electrical ionizing devices (A.C. static neutralizers or D.C. charging systems) in which discharge electrodes, such as emitter points, are connected to a high voltage power supply and in adjacently spaced disposition behind a grounded foraminous grille, wiper means, such as brushes, for cleaning accumulations of particulate material electrostatically adhered to the electrodes themselves. The brushes are preferrably mounted upon the grille and have bristles passing through slots therein to enable the operator before ionization is instituted to sweep the brushes from an out-of-the-way position relative to the emerging ion flow across the electrodes to effect the cleaning and then clear of said electrodes.
