Abstract

Abstract A flash extender, for a photographic camera adapted to receive and actuate a percussively ignitable flashlamp, having a socket, at least one push rod and a base. Insertion of the extender base into the camera flash socket aligns a push rod with the camera flash firing mechanism. Operation of the shutter release mechanism of the camera actuates the camera flash firing mechanism which causes the aligned push rod to be urged upwardly, thereby actuating a percussively ignitable flashlamp held in the socket of the flash extender. In a preferred embodiment, operation of the camera flash indexing mechanism causes rotation of the camera flash socket and the extender therewith to place a fresh flashlamp in firing position.
