Abstract: An ammunition positioner for upright ammunition shells has an arm mounted on a base, capable of being extended parallel to the plane that the shell stands on. The positioner has a pincher-like pickup with two jaws that pivots parallel to that plane. The pickup and its jaws are both controlled by a motor that is secured to the base. The motor's output wheel is coupled to the intake wheel of a transmission by way of a rotating splined shaft and a hollow shaft. The splined shaft is mounted in the base and parallel to the positioning arm. The hollow shaft is coaxial with the splined shaft and is mounted in and parallel to the positioning arm. A sleeve travels back and forth on the splined shaft and couples the hollow shaft to the splined shaft such that the former will rotate along with the latter. The transmission has two cogwheels, one of which is always coupled to the intake wheel and the other of which is coupled to and can be uncoupled from the intake wheel by a gear that can be disengaged.

The tube is mounted in a bearing ring that rotates around the axis of the tube and is itself mounted on another bearing ring and rotates around an axis at an angle to the axis of the tube. The second bearing ring rotates in the turret around another axis at an angle to the first axis. The angle between the first and the second axes of rotation equals the angle between the first axis of rotation and the axis of the tube. Both bearing rings can be driven around their axes of rotation. The slant-ring bearing is a subassembly inside the turret and the flange that secures the second bearing ring is secured stationary to the turret. The flange that the tube is mounted on and that secures the first bearing ring is secured non-rotating to the turret.
