Abstract
An escapement mechanism for successively releasing rectangular groups of articles from an upright stack. The articles are of the type having reduced top ends and enlarged bottom ends. The articles are held within an upright hopper that guides the stack gravitationally toward the escapement mechanism. Successive groups of articles are engaged by a first stop mechanism at a first elevation and are lowered thereby to a second elevation. A retractable support is located at the second elevation to receive and support the successive groups of articles. While articles are resting upon the retractable support, the stop means is moved upwardly again to engage the bottom sides of the next successive group of articles and lift them upwardly from engagement with the top ends of the article group presently supported on the retractable support. Once to successive groups become disengaged from one another, the support is retracted to allow one group to fall gravitationally to a transfer mechanism. The stop mechanism is then again operated to gradually lower the next successive group of articles toward engagement on the retractable support.
