Abstract
A cartridge feeding drum magazine for use with semiautomatic or full-automatic firearms such as pistols or submachine guns. A rotor is provided within a drum housing to define an annular cartridge-receiving channel, and a magazine extension joins the drum at 90.degree. thereto for insertion within the existing magazine receptacle of a firearm. The rotor, which is spring-biased for rotation, carries a separate magazine spring within a housing, so that the magazine spring remains enclosed while the rotor turns to feed cartridges. The magazine spring moves out of its housing to urge remaining cartridges through the magazine extension, after cartridge-feeding movement of the rotor is completed.
Claims9
Drum magazine apparatus for supplying cartridges to a firearm, comprising:
- means defining a cylindrical housing;
- a rotor concentrically mounted within said housing to define an annular channel for receiving a plurality of cartridges;
- extension means connected to said housing and defining a cartridge feeding channel in communication with said annular channel, said extension means being configured to fit within a magazine receptacle of a firearm so as to define a path of cartridge movement from said annular channel to the firearm;
- guide means located adjacent the communication between said annular channel and said extension means to guide cartridges moving from said annular channel to said cartridge feeding channel;
- a pair of covers disposed on respective ends of said cylindrical housing to enclose said housing;
- said rotor having means defining an inwardly facing surface in proximate relation to said covers;
- and
- each of said covers including means operative to slidingly fit within said inwardly facing surface of said rotor so as to position said rotor in predetermined location within said cylindrical housing.
