Abstract
A cartridge magazine for firearms comprises a key insertable through a slot in the end panel of the magazine for engaging the spring engaged elevator upon which the shells are supported. The slot includes a series of transverse or lateral branches spaced longitudinally on the panel for receiving the key and locking the elevator in position. The magazine thus may be loaded with cartridge shells in stages as defined by the lateral locking branches. After loading is completed, the key may be removed from the magazine and clip so that the latter may be inserted into the firearm with which it is used. In an alternatively preferred embodiment, optional marking means are positioned on top of the magazine for placing an identifying marking on each cartridge shell.

A new and improved cartridge magazine for a firearm comprising in combination:
- a housing, said housing having first and second opposed end walls, first and second opposed side walls, a bottom wall and a top end opening, said housing defining an interior cavity for storing a multiplicity of cartridge shells one on top of the other with the longitudinal axis of each cartridge shell being substantially orthogonal to the longitudinal extent of said housing,
- said first end wall having a slot therein extending longitudinally between said top end and said bottom wall, said slot having at least one notch laterally extending from said slot in the plane of said end wall intermedially of the longitudinal extent of said slot,
- elevator means disposed in said cavity for longitudinal movement therein, said elevator means having an end face confronting said slot in said first end wall and key receiving means in said end face,
- resilient means in said cavity between said bottom wall and said elevator means for urging said elevator means toward said top end opening,
- and key means for selective insertion into said key receiving means through said slot to engage said end face of said elevator whereby movement of said key enables movement of said elevator in said cavity and selective engagement of said key with said slot in said end wall and said at least one notch laterally extending from said slot, said key means further comprising a loop at one end thereof for engagement by the thumb of a user's hand when said bottom wall of said housing is resting in the palm of said user's hand with said housing in an upright position.
