ABSTRACT:
An improved flashlamp assembly which utilizes a plurality of percussively-ignitable flashlamps disposed on an elongated support member. Firing of the flashlamps is accomplished using a spring-loaded ratchet, a movable carriage, and a striking mechanism, e.g. helical torsion spring, positioned on the movable carriage and in engagement with the ratchet. The spring engages and fires each of the lamps in response to movement of the ratchet and carriage members. The improvement comprises providing a longitudinal passage within the ratchet member to permit movement of the carriage therein. An improved firing mechanism for the assembly is also disclosed.
