Firing lock with safety system for self loading fire arms

A fire arm of the self loading pistol type having a reciprocating slide carrying an inertia-operated firing pin, a firing lock comprising a hammer, sear, trigger, trigger bar, ejector and main spring, and a safety catch comprising an arbor rotatably mounted in the frame of the fire arm, and manual lever means located on the outside of the frame for rotating said arbor in either direction from a rest or off position in which the fire arm can be operated, said arbor being rotatable in one direction to an end position in which the hammer in either the cocked or uncocked position is locked against rotation by respective engagement means on the arbor, and said arbor also being rotatable in the other direction to move a detent member pivotally mounted in said frame to move the ejector upwardly and forwardly to engage said firing pin and to withdraw its striking end, against which the hammer strikes in operation of the fire arm, completely into the slide, and thereafter to release the hammer from cocking engagement with said sear, whereby said hammer is returned to the uncocked position without danger of discharging a live cartridge in the breech of the fire arm.
