  • Patent number: 4168928
    Abstract: A magazine adapted to feed trapezoid-shaped objects from its bottom, with each successive object being pushed sideward out of the magazine from its thick side, such that the first portion of the object to emerge from the magazine is the thin side. The magazine typically has a fixed front wall and a fixed back wall, at least one of which may be adjustable in order to accommodate objects of various widths. The objects rest face-to-back in a stack between the two walls. A floor supports the objects, and at least a portion of the floor is movable; and there is a gap between the movable floor portion and the bottom edge of the front wall. A portion of the movable floor is yieldable downwardly as an object is being pushed out of the magazine, and preferably this portion constitutes a spring-biased roller over which an object passes as it is ejected from the magazine.
