ABSTRACT:
A transporter for storing and feeding linkless rounds of ammunition, including live rounds as well as spent cartridge casings, has a generally cylindrical drum frame assembly with longitudinal rails that retain the rounds in rows, the rounds facing radially inwardly toward an axis of the drum. The drum rotates slowly and continuously during operation, bringing the rows of rounds into the area of an internal conveyor for removing rounds from one row while preferably returning spent cartridge casings to another row, proceeding row by row around the drum. The internal conveyor is preferably parallel to the axis of the drum and parallel to the rails, being mounted at least on one end of the drum by a radial arm. Drive and gearing means slowly advance the radial arm in synchronism with rotation of the drum during processing of a given row of rounds, and angularly index the internal conveyor stepwise to a next row upon completion. Preferably the drive means includes a cam and cam follower, one of which is on the radial arm and the other of which rotates on a fixed axis spaced from the drum axis.
