DRIVE AND QUICK STOP FOR A WEAPON WITH PREFERABLY LINEAR BREECH OR AMMUNITION FEED
First Claim
1. A drive provided with a quick stop device operably connected to a breech, or a breech support, of a weapon, wherein the breech or breech support is moveable between a front limit position and a rear position in an axial direction with respect to a weapon barrel of the weapon, wherein the drive comprises:
- (a) a motor;
(b) a chain that is driven by the motor and to which at least two driver studs are fitted;
(c) at least two sprocket wheels arranged underneath the breech, wherein the chain with the at least two driver studs is passed around the at least two sprocket wheels;
(d) a slide mounted in a guide disposed at a bottom on the breech, or at a bottom on the breech support, so that the slide is moveable transversely with respect to a firing direction, and a groove extends over the entire width of the slide, wherein a respective one ofthe at least two driver studs moves the breech via the groove either, forward in the firing direction or backward after a shot is fired, wherein duringthe times in which the breech is stationary in the front limit position, the driver stud that transports the breech forward is moved out of the groove and the driver stud is moved backward on a first weapon side and without the breech, andwhen a shot has been fired, the slide moves to the first weapon side, and when no shot has been fired, the slide remains in a first position in which the slide has been moved away from the driver stud so that neither driver stud is in position to drive the breech to the rear position.

Abstract
A drive for a breech/breech carrier renders it axially adjustable relative to a weapon barrel. The drive includes a motor, two engaging cams mounted on a chain arranged below the breech and guided around two sprocket wheels. A slide is mounted in a guide at the bottom of the breech/breech carrier so as to move at a right angle to the direction of fire, with a groove extending over its entire width. The respective engaging cam entrains the breech in forward motion relative to the direction of fire, or in reverse motion, once the shot is fired, and transports the breech forwards, is displaced from the groove, and moves backwards without the breech, thereby allowing breech rest periods in a forward position. During firing, the slide moves, whereas it remains stationary when no shot is fired so no further engaging cam can entrain the breech backwards.
