Abstract: In a multi-rack can vending machine, an article release mechanism for controllably releasing articles from an article rack automatically into a vertical access as the article level in the access is lowered. The article release is a spring retained flapper plate which pivots about a pivot support to release multiple articles on demand. The flapper plate is normally retained against the force of the spring in an article retaining position until the level of articles in the access is sufficiently low to allow the flapper plate to pivot without contacting the uppermost article. Generally, two articles of sufficient weight are required on the flapper plate in order to overcome the force of its retaining spring to actuate the pivotal release of the two articles into the access.
