Arrangement for determining the presence of a cartridge in a cartridge chamber of a weapon

摘要

A cartridge casing detection system for detecting the presence or absence of a cartridge casing in the cartridge chamber of a machine cannon. A lever is pivotally mounted in a recess of the housing of the weapon. A sensor is connected to a switch. One free end of the lever is adapted to coact with the sensor tip and the other free end of the lever is adapted to coact with the edge of the cartridge casing when the latter is disposed in the cartridge chamber of a weapon. A breech block is reciprocally mounted in the weapon and includes a pocket past which the other free end may extend for contacting the cartridge casing when the breech block is in its forwardmost operative position.
