ABSTRACT:
A firing mechanism in which the hammer and trigger are interconnected by gears, so that the hammer can be cocked and fired simply by pulling the trigger in what is commonly referred to as double-action. The hammer is mounted so that it can pivot independently of the gears in order to discharge a cartridge. A sear connects one of the gears to the hammer so that it can be cocked by means of the trigger and then released when the trigger is fully retracted. A safety feature is also provided by mounting the hammer so that it is normally out of alignment with the firing pin and, thereby, can not accidentally discharge the gun. However, when the trigger is pulled the hammer is shifted bodily to bring it into alignment with the firing pin.
