Abstract
An automatic weapon is provided with a device for increasing the rate of fire. The breech mechanism of the weapon is controlled by means of recoil movements which arise on discharge of the weapon, and by an operating cam and spring member included in the breech mechanism. Two case ejectors are disposed for arresting the breech block in the total recoil position of the breech and holding the breech block in the open position for ramming-home of a new round. In the arrested position of the breech block, the ejectors are exposable to the new round during its ramming cycle. A portion of the kinetic energy inherent in the round is transmitted to the ejectors which, may accompany the round and release the breech block for actuation by the spring member towards its closed position. The operating cam is movably disposed at least when the breech is located in the total recoil position. The spring member begins to actuate the breech block on its movement towards the arrest position at an earlier stage than total recoil position.
