DEFINITION

Classification: 89/33.01

CARTRIDGE FEEDING:

(under the class definition) Subject matter to hold and/or feed a plurality of cartridges to a gun. The gun may be automatic, and the inclusion in the claims of conventional explosion-operated means, such as a recoiling barrel on a gas piston, will not prevent classification in this or indented subclasses where the improvement lies in the feeding device.

SEE OR SEARCH THIS CLASS, SUBCLASS:

45+, for devices for loading single cartridges, charges or projectiles to guns.

125+, for significant automatic gun structure in addition to cartridge feeding.
