Abstract
The invention relates to an improvement in a multiple-shell weapon magazine or clip of the type employing either one or a pair of transversely-curved negator springs fastened to a particular sidewall of the cartridge chamber alongside the stack to lift the shells one-at-a-time through the open top thereof on a follower which is characterized by the spring or springs being so arranged and sized that the rearmost incurled edge of one seats within the annular grooves encircling the rear ends of the shells in the stack while the foremost incurled edge of the same or another spring curls around the bullets thereby alleviating any undue pressure applied to the shell casings by the medial portion of one spring or the adjacent edges of the pair that otherwise could cause the stack to jam. The invention also encompasses the method of preventing the shells from jamming in such a magazine by sizing and positioning the spring edges in the manner aforementioned.
