Abstract:
A firing mechanism for use in a firearm to fire a non-impact fired cartridge, said firearm having a reciprocating firing probe for communicating electronic signals from a firing apparatus to said cartridge upon forward movement of said firing probe into contact with said cartridge, said firing mechanism comprising:a trigger supported within a frame of said firearm for rotational movement from a recovered trigger position to a partially-cocked position to a let-off position to a fired position; a hammer rotatably supported within said frame and having a hammer foot selectively engagable within a trigger pocket of said trigger for movement with said trigger from said partially-cocked position to said let-off position; a sear captured within a sear pocket of said hammer and engagable with a trigger post of said trigger for movement with said trigger from said partially-cocked position to said let-off position; a main spring operatively engaged between said hammer and said trigger to bias said hammer and said trigger in opposite directions of actuation such that said main spring is compressed by movement of said trigger from said recovered position to said fired position and simultaneously compressed by movement of said hammer from said recovered position toward said let-off position; a transfer bar engaged within said trigger pocket of said trigger and reciprocally moveable into and out of engagement with said trigger pocket during rotational movement of said trigger; and said hammer and trigger being further configured so that when said trigger is actuated beyond said let-off position, said hammer disengages from said trigger and is rotationally urged by said main spring toward contact with said transfer bar resulting in forward movement of said firing probe into contact with said cartridge.
