Abstract: There is proposed an ejector device (6) for grenade projector or mortar projectiles (1), which permits simulation of mortar firing even in halls or very limited areas. It is known that blank cartridges (17) for rifles, pistols or bolt firing devices have only a slight degree of scatter in terms of gas pressure. Therefore the ejection speed of a piston (13) which is inserted into the ejector device (6) and which is driven by the powder propellent gases of the blank cartridge (17) is always the same. In that way it is always possible to achieve the same firing ranges of only a few meters.

Abstract: To permit single firing in a machine gun by a mechanical method, a trip lever is moved by a control surface attached to the weapon housing during the weapon recoil after triggering a shot. This motion causes the trip lever to disengage a coupling on the crankshaft. Because of this, the trigger plate can return to its starting position by means of spring force, independently of the position of the cocking lever. The recoil breech can then be caught by the trigger in the weapon housing. If the cocking lever is moved back, it again couples because of the spring.

Abstract: With the device a repositioning of ammunition feeds of an automatic weapon into various feed positions and a secured position is achieved. The selective positioning is achieved by a lever which is pivotally supported alongside a drive shaft and abuts by an integrally formed cam at one end face of a pivoting support part axially against a sleeve which is axially displaceable on the drive shaft. The sleeve is under the biasing force of a spring. The end face of the sleeve biasing toward the pivoting support part of the lever possesses also a cam which is in operative connection with a cam of the pivoting support which upon engagement effects a coupling driving engagement of the lever with the shaft. The mechanism acts to hold the lever of the ammunition feed in a respective position by means of the spring.

Abstract: The safety lock for a barrel of automatic weapons comprises a breechblock carrier whose face facing the barrel confronts a slide. This slide is movable essentially perpendicular to the longitudinal axis of the barrel into a recess provided in the outside surface of the barrel, if the barrel is correctly locked.

Abstract: A detonator lock on an automatic firearm, with a breech mechanism which is displaceable from a rear position into a priming position, comprises a safety device which can be pushed into the path of the closing device and is operatively connected with the support piece of the detonator. The safety device can be rigidly barred by a spring-supported lock bolt, the lock bolt which is held in position by a control element which is inserted in the path of the safety device before the safety device has moved into either the secured or the priming position.
