A cleaning device for guns in which a cleaning brush fastened to a brush carrier is moved to-and-fro in the barrel by means of a rod. A drive unit with drive wheels which can be engaged with the rod is arranged in the front of the muzzle of the gun so that the cleaning operation can be simply carried out with a small expenditure of time and labor.

Cleaning device for guns

A device for centering retention of ammunition includes an ammunition receiver having spring elastic holding elements acting in the radially inward direction in the tapering section of the ammunition and gripping elements holding the ring of the cartridge of the ammunition arranged in the bottom area of the ammunition. The holding elements are made up of leaf springs fastened to the ammunition receiver in the direction of the generators of the ammunition in a forward and a rear clamping location in order to assure retention of the ammunition without wear in case of severe jolting movements and to assure safe transfer of the ammunition into the cartridge chamber without damaging it. Each leaf spring comprising a recess or inward protrusion acting on the ammunition in its tapering section and a free end projecting past a forward clamping location in a radially inward direction.

Device for the centering retention of ammunition in an ammunition

A loading device with a rammer, arranged for coupling with ammunition bases, exhibiting a transport and coupling segment. The coupling segment exhibits a plurality of grippers with claws adapted to engage an undercut base of ammunition. The bearing member for the grippers is movable with respect to the transport segment with a first limit position, corresponding to the maximum distance of the bearing member from the transport segment. The bearing member has a stop element for fixing the position of the bearing member relative to the ammunition base. After the rammer is moved against the base the transport segment is moved toward the coupling segment. The grippers are moved out of their rest positions assumed by the action of a resetting mechanism, and into their gripping positions against the edge of the base of the ammunition by an actuating member.

Loading device for large caliber weapons

An armored vehicle with a rotatable turret, e.g. a tank, has its gun (cannon) supplied from a munitions bunker behind the turret in which the munitions rounds are stored in tubes inclined at angles less than 90.degree. to the axis of the gun when the breech thereof is aligned with an opening in the magazine through which the rounds are fed from a tunnel in the magazine aligned with the gun. The rounds lie in substantially horizontal planes and are withdrawn from storage tubes by a device movable axially along the tunnel and swingable into alignment with each tube to withdraw the round therefrom and feed it through the opening into the breech of the gun.
