| Abstract: |
A magazine filled with ammunition that can be quickly and easily attached to and detached from a firearm. It has a snail-shaped housing with a laterally offset chimney section that has an outlet port at its top end for feeding the ammunition into the firearm. The magazine is capable of being attached to the firearm at two 180 degree separated positions to accommodate a left or right handed person. There is an annular chamber in the housing of the magazine and it contains a spring-loaded drum. A pair of laterally spaced cog gears are mounted on the drum for capturing ammunition shells and transporting them along a circular axis until they reach the vertical linear axis of the chimney section. A follower assembly pushes the ammunition shells up through the chimney section. A shell retainer unit is mounted in the chimney section for preventing shells from exiting its outlet port when the magazine is detached from the firearm. The shell retainer unit is deactivated by a depressor member that moves downwardly when the magazine is attached to the firearm.

What is claimed is:
1. A magazine for a firearm comprising:
- a housing having a front wall, a rear wall, a top wall, a bottom wall, a left side wall and a right side wall;
- said front wall having an inner surface and said rear wall having an inner surface; a tubular drum having an outer surface also has opposite ends that are journaled in said respective inner surfaces; an annular chamber is formed in said housing with the inner surface being defined by the outer surface of said tubular drum and the outer surface of said annular chamber being defined by said top wall, said bottom wall, said left side wall and said right side wall;
- said housing having a substantially vertical tubular chimney section having a top end, a bottom end, a front wall and a rear wall; an outlet port is formed in the top end of said chimney section and an inlet port is formed in the bottom end of said chimney section; said tubular chimney section having a linearly extending chamber and its bottom end is in communication with said annular chamber;
- means for spring loading said drum so that the drum will rotate with respect to the front and rear walls of said housing;
- means on the outer surface of said tubular drum for capturing ammunition shells so that they can be carried along said annular chamber toward the inlet port of said chimney section as said drum rotates;
- a shell ammunition follower assembly having a front end and a rear end, said shell ammunition follower assembly travels immediately behind a last round of ammunition and pushes it forwardly toward the outlet port of said chimney section of said magazine;
- means for connecting the rear end of said shell ammunition follower assembly to said rotating drum; and
- means for limiting rotation of said tubular drum to less than 360 degrees comprising a stop limit wall that extends into said annular chamber to abut the rear end of said shell ammunition follower assembly.
