Abstract
An ejection seat firing mechanism has a primary cartridge and a firing pin within a housing. A firing head is outside the housing coaxial with the primary cartridge and the firing pin, and a nut affixes the firing head to the firing pin thereby enclosing the housing. A first bore is formed through the flange of the housing and a second bore is formed in the nut spaced from the housing and aligned with the first bore in spaced parallel relation with the axis. A torquing shaft with an internally threaded axial coupling bore formed therein extends a determined distance into the torquing shaft. A spring is coaxially positioned around the torquing shaft and has a top end abutting the nut and a spaced opposite bottom end biasing the torquing shaft toward the flange. A bolt member extends through the first bore and is threadedly coupled with the torquing shaft via the coupling bore. The bolt provides a visual and sensory indication that the primary cartridge is installed and the firing head is torqued.
