Abstract

The arrangement for emergency actuating of the firing pin of a machine cannon having an exterior drive includes a percussion hammer that is loaded by a coil spring for the direct loading of the firing pin mounted in the breech block via an intermediate rod member. When in a loaded position and therefore ready for an emergency actuation, the percussion hammer is secured in its operating position by means of an arresting spring which engages with a pair of diametrically opposite nose members into an abutments forming part of the breech housing.
