Firearm and magazine construction
First Claim
1. A firearm, comprising a housing, a barrel mounted on said housing having a cartridge chamber, a magazine having a cartridge receptacle portion and formed in said housing and having a passage for cartridges extending between said receptacle portion and said cartridge chamber, said receptacle portion being a drum-like member rotatable in said housing and constructed to contain a plurality of cartridges therein in parallel relationship to said barrel, cartridge transport means in said magazine receptacle portion engageable with the cartridge therein to move said cartridges successively into alignment with said cartridge chamber, and a cartridge clip loading opening defined in said magazine housing communicating with said cartridge receptacle portion and having means thereon for positioning a cartridge loading container for transferring cartridges therefrom into said magazine receptacle portion and into association with said cartridge transport means, said cartridge receptacle portion including said drum-like member and a tangentially extending portion forming said passage, said tangentially extending portion being shiftable upon rotation of said drum-like portion between a position in which the upper end thereof is aligned with said cartridge chamber and a position in which the upper end thereof is aligned with the loading opening.

Abstract
A firearm comprises a stock having a barrel mounted thereon for the magazine chamber associated with the stock which has a passage for the cartridges extending between an interior chamber of the magazine and the cartridge chamber associated with the barrel. The magazine is constructed to contain a plurality of cartridges therein for example in an annular arrangement around a rotatable cartridge transport star. The cartridges are arranged in parallel relationship to the magazine chamber and they are moved by the transport mechanism during the firing operation successively into association with the cartridge chamber of the barrel. The magazine is also provided with an opening which provides means for mounting a cartridge clip or carrier so that cartridges may be loaded into the magazine through the opening which is communicable with the chamber in the magazine for the cartridges. In one embodiment, the communication is established by rotating an interior holder arranged within the magazine so as to shift a tangentially extending passage portion which extends from the cartridge chamber in the magazine to the cartridge chamber associated with the barrel into a position in which the passage is aligned with the loading opening rather than with the cartridge chamber of the barrel. In another embodiment, the loading opening communicates upon insertion of the clip directly with an annular cartridge space in the magazine on one side thereof after a cover closing the opening is positioned in a location to block the further upfeed of the cartridges into alignment with the barrel cartridge chamber.

- 1. A firearm, comprising a housing, a barrel mounted on said housing having a cartridge chamber, a magazine having a cartridge receptacle portion and formed in said housing and having a passage for cartridges extending between said receptacle portion and said cartridge chamber, said receptacle portion being a drum-like member rotatable in said housing and constructed to contain a plurality of cartridges therein in parallel relationship to said barrel, cartridge transport means in said magazine receptacle portion engageable with the cartridge therein to move said cartridges successively into alignment with said cartridge chamber, and a cartridge clip loading opening defined in said magazine housing communicating with said cartridge receptacle portion and having means thereon for positioning a cartridge loading container for transferring cartridges therefrom into said magazine receptacle portion and into association with said cartridge transport means, said cartridge receptacle portion including said drum-like member and a tangentially extending portion forming said passage, said tangentially extending portion being shiftable upon rotation of said drum-like portion between a position in which the upper end thereof is aligned with said cartridge chamber and a position in which the upper end thereof is aligned with the loading opening.
- 6. A firearm magazine, comprising an outer magazine housing, a drum-like rotatable receptacle in said housing, said housing having a top portion alignable with a firearm cartridge chamber, and having a side portion with a loading opening therein, a tangentially extending part connected to said drum-like receptacle and forming a tangentially extending connecting passage selectively positionable tangentially between said drum-like receptacle and the cartridge chamber and tangentially between said drum-like receptacle and said leading opening, said drum-like receptacle being rotatable to position the tangentially extending portion selectively into alignment with the cartridge chamber and with the opening.
