Abstract
Abstract Method and apparatus for loading cartridges into a relatively large capacity firearm magazine of, for example, the rotating drum type is disclosed and includes structure defining a plurality of generally parallel extending slots for receiving cartridges in a horizontal attitude and arranged as a plurality of generally parallel, vertical columns of superposed cartridges lying in the slots. The structure also includes a sliding panel with a single cartridge-passing opening therein, which opening may be selectively aligned with any one of the cartridge columns. The cartridge-passing opening is then aligned with a magazine loading port and the cartridges transferred one at a time from the bottom of a column into the magazine. When a column is exhausted, the structure is shifted so as to align a different column with the aperture and loading port whereupon that column is transferred one at a time to the magazine. Typically, the transfer involves not only the appropriate alignment but also the rotating of the magazine in a sense opposite its normal direction of rotation during firearm operation. Refilling of the cartridge dispensing device may be facilitated by the provision of a second sliding panel so that the slot defining structure may have those slots exposed on two adjacent faces with one face juxtaposed with the panel containing the cartridge passing opening and the other face being selectively exposable for refilling the device.

Claims Analysis
Total Claims: 10
Claim 1
Independent Claim
184 words
An apparatus for loading cartridges into a firearm magazine through a loading port thereof comprising: first means formed generally as a rectangular parallele-piped defining a plurality of generally parallel extending elongated slots, each for receiving a laterally adjacent sequence of cartridges with each slot communicating with first and second adjacent faces of said first means; second means comprising an elongated strip like panel slidingly received by the first means along the first face for forming a cartridge transfer path between one of said slots and the magazine loading port for transferring cartridges laterally one at a time from the one slot directly to the magazine while precluding cartridge movement from said slots other than the selected one slot, the first and second means being relatively moveable so that the transfer path can be successively aligned with each of said slots for the successive transfer of cartridges from each of said slots in turn; and a side panel for slidingly engaging the first means along the second face to prevent inadvertent cartridge removal while allowing ready access to the first means for placing cartridges therein.
Claim 2
Independent Claim
184 words
An apparatus for loading cartridges into a firearm magazine through a loading port thereof comprising: first means formed generally as a rectangular parallele-piped defining a plurality of generally parallel extending elongated slots, each for receiving a laterally adjacent sequence of cartridges with each slot communicating with first and second adjacent faces of said first means; second means comprising an elongated strip like panel slidingly received by the first means along the first face for forming a cartridge transfer path between one of said slots and the magazine loading port for transferring cartridges laterally one at a time from the one slot directly to the magazine while precluding cartridge movement from said slots other than the selected one slot, the first and second means being relatively moveable so that the transfer path can be successively aligned with each of said slots for the successive transfer of cartridges from each of said slots in turn; and a side panel for slidingly engaging the first means along the second face to prevent inadvertent cartridge removal while allowing ready access to the first means for placing cartridges therein.
Claim 3
Dependent Claim
38 words
The apparatus of claim 1 wherein the strip-like panel has a single elongated cartridge-passing opening near the middle thereof, the apparatus further including a removable sliding cover to be substituted for the strip-like panel during periods of non-use.
Claim 4
Dependent Claim
55 words
The apparatus of claim 1 wherein the second means can be placed in registry with the loading port and the first means thereafter moved relative to the magazine and the second means to sequentially align slots with the loading port and further comprising means for maintaining the second means in registry with the loading port.
Claim 5
Dependent Claim
23 words
The apparatus of claim 1 wherein the first means is formed of a transparent material to allow a user to monitor cartridge movement.
Claim 6
Dependent Claim
48 words
The apparatus of claim 1 wherein the first means includes slots along the second face and flanges along the first face, the flanges along the first face slidably receiving the second means and the slots along the second face slidingly receiving said panel to prevent inadvertent cartridge removal.
Claim 7
Dependent Claim
68 words
The apparatus of claim 5 wherein said side panel overlies said second face and has along one edge a laterally extending flange which is coplanar with said flanges; said second means having slots which slidably receive said flanges and said panel flange, said strip-like panel cartridge transfer path including a cartridge-passing opening registerable with any selected one of the first means slots which opens through said first face.
Claim 8
Independent Claim
120 words
An apparatus for storing cartridges comprising a cartridge-carrying block having two flat faces that intersect, grooves on opposite sides of one of said two faces, a flat panel slidably received by said grooves in overlying relation to said one face, the other face having flanges on opposite sides thereof, said panel having a flange portion alignable with said flanges, a plurality of elongated slots in said block which are spaced apart and parallel, said slots opening through said one face and through said other face, said flat panel closing the one face openings of said slots, and an elongated closure cover having slots slidably received over said flanges in closing relation with the other face openings of said elongated slots.
Claim 9
Independent Claim
120 words
An apparatus for storing cartridges comprising a cartridge-carrying block having two flat faces that intersect, grooves on opposite sides of one of said two faces, a flat panel slidably received by said grooves in overlying relation to said one face, the other face having flanges on opposite sides thereof, said panel having a flange portion alignable with said flanges, a plurality of elongated slots in said block which are spaced apart and parallel, said slots opening through said one face and through said other face, said flat panel closing the one face openings of said slots, and an elongated closure cover having slots slidably received over said flanges in closing relation with the other face openings of said elongated slots.
Claim 10
Dependent Claim
38 words
The apparatus of claim 7 including a transfer panel shaped substantially like said closure cover and provided with like slots, said transfer panel having a cartridge-passing opening therein which is registrable with one of said other face openings.
