Selective actuating mechanism for percussive photoflash lamp array
Abstract
Abstract LATCH ENGAGING ONE OF A PLURALITY OF EVENLY SPACED PINS ON THE GEARS. TO FLASH A LAMP, THE LATCH IS MOMENTARILY RELEASED TO PERMIT ROTATIONAL INDEXING OF THE GEARS, WHEREUPON ONE OF THE RAMPS RELEASES A STRIKER. IN ANOTHER EMBODIMENT, A SPRING LOADED SLIDABLE BAR WITH RAMPS IS LINEARLY INDEXED IN A SIMILAR MANNER. FOR A PHOTOFLASH ASSEMBLY COMPRISING A PLURALITY OF PERCUSSIVELY-IGNITABLE FLASHLAMPS ARRANGED IN AN ARRAY WITH RESPECTIVELY ASSOCIATED REFLECTORS AND PREENERGIZED STRIKER SPRINGS, A SELF-ENERGIZED SELECTIVE ACTUATING MECHANISM FOR SEQUENTIALLY RELEASING THE STRIKER SPRINGS TO FIRE RESPECTIVE FLASHLAMPS IN RESPONSE TO SUCCESSIVE INDEXING. IN ONE EMBODIMENT, THE SELFENERGIZED ACTUATING MECHANISM COMPRISES A COPLANAR TRAIN OF INTERMESHING SPUR GEARS HAVING A NUMBER OF CIRCUMFERENTIALLY SPACED PROJECTING RAMPS. THE LAMPS AND STRIKER SPRINGS ARE SUPPORTED ON THE END SURFACES OF SHAFTS UPON WHICH THE GEARS ARE MOUNTED, WITH THE STRIKERS RADIALLY PROJECTING OVER THE SURROUNDING GEAR TO LIE IN THE PATH OF TRAVEL OF THE RAMPS. THE GEARS ARE SPRING LOADED TO ROTATE WHEN NOT LOCKED IN PLACE BY A
