An article dispensing apparatus embodied, for example, as a vending machine, including a controllably positioned suction hose dispenser for retrieving articles from a storage area. In one embodiment, an airflow control mechanism, i.e., a vacuum or suction release (i.e., breaker), is used to facilitate a "quick-release" of the article being handled. A mechanical linkage constructed and operating in accordance with the invention is used to activate, for example, the breaker in response to mechanical contact by the article handling mechanism. Such operation thereby causes a rapid equalization of air pressure inside the housing towards ambient when it is time for the article handling mechanism to release the selected article. In accordance with one aspect of the invention, the linkage comprises an elongated rotating member having a first portion adapted for being operated (directly or indirectly) by the article handling mechanism at the point in its article handling motion when it is time to release the article being handled, and a second portion adapted to operate, for example, a quick-release suction breaker.
