ABSTRACT:
An ejector system for the extraction of cartridge casings from a tubular weapon provided with two ejector levers that are pivotal about an axis. Prior art ejector systems of this type have the drawback in that the ejector claws which pull the cartridge casing out of the cartridge chamber after firing are fastened directly to the ejector levers so that, due to the circular arc movement of the ejector claws, the cartridge casings are ejected in an undefined direction of flight from round to round. However, large caliber weapons, particularly those equipped with automatic loading mechanism, require a defined ejection path of the cartridge casings. To avoid the above drawbacks, the disclosed ejector system fastens each ejector claw to an ejector that is linearly displaceable parallel to the longitudinal axis of the gun barrel. The ejectors in turn are provided with respective recesses into which the ejector levers engage in a displaceable manner so that, when the ejector levers are pivoted, the ejectors are displaced linearly.
