Abstract
1458088 Corona charging apparatus XEROX CORP 18 July 1974 [18 July 1973] 31932/74 Heading H1X A corona generating device comprising at least one discharge electrode 32 includes an element 38 adapted to traverse said electrode, said element having at least one edge which is operative to deflect and scrape said electrode to remove contaminants therefrom, and means 53, 51, 55, 58 for traversing said element along said electrode. The wire electrode 32 is secured between two clamps 34 mounted one at each end of a channel 61 in a grounded metal shield 31 provided with a slot 35, and is connected to a supply wire 33. The element 38 has a slot 40 accommodating the wire 32 and bounded by two arms 41 which pass through the slot 35 and are pivoted on a pin 44 in a carriage 42. A tab 57 on carriage 42 is connected by a cable 55 to a knob 58 which is pulled to move the carriage to the end 73 of the slot 35. A tab 52 is connected by a cable 51 to a spring-loaded rewind mechanism 53 which returns the carriage to the home end H of the slot 35 in which position ramps (not shown) on the sides of the channel 61 disengage the bottom of the slot 40 from the wire 32. As a consequence of the pivotal mounting of the element 38, the wire 32 is deflected and scraped by one edge of the bottom of the slot 40 when the carriage is moving in one direction and by the opposite edge when the carriage is moving in the opposite direction. Brushes 60 on the element 38 clean the channel 61. The element may be slit circumferentially to provide resilient arms on which the brushes 60 are mounted (Fig. 8, not shown). An alternative embodiment (Figs. 6 and 7, not shown) provides combined transverse and longitudinal pivoting of the element 38.
