DEFINITION
Classification: 431/359
Plurality of bulbs associated for sequential ignition:
(under subclass 358) Apparatus having means interconnecting a plurality of bulbs so that (a) upon percussive actuation of a single means, a successive one of said bulbs will be ignited, or (b) upon a single actuation of a means, a plurality of
bulbs will ignite in a successive order with a predetermined time delay automatically interposed between successive ignitions, or (c) upon ignition of one of the bulbs of the sequence of bulbs, by activating an electrical means, a switch means or other electrical circuitry is conditioned so that when the electrical means is again activated, another bulb in the sequence will be ignited, or (d) a structural means provided to support a plurality of bulbs as a unit in which each bulb is provided with its own percussive ignition means.
(1) Note. Included in this subclass are those multibulb units having a switch means which is conditioned upon the ignition of one bulb to permit ignition of another bulb by electrical means, or a unit of percussively actuated bulbs having means whereby each bulb is struck separately.
