Abstract : A firing mechanism for detonating a plurality of percussion primers is presented. An explodable means and at least one percussion primer are disposed at opposite ends of a housing defining a cavity for transmitting explosive energy from the detonated explodable means to each of the percussion primers for firing the percussion primers. An orifice plate, secured within the cavity between the explodable means and the percussion primers is provided with plurality of apertures for providing passageways for transmitting the explosive energy from the explodable means to the precussion primers. The apertures are calibrated for metering the quantity of the explosive energy transmitted to the percussion primers and for providing substantially simultaneous initiation of the plurality of percussion primers. The apertures are off-set for substantially avoiding the striking of the percussion primers by fragments from the explodable means. (Author)
