Abstract
Abstract An improved dispensing drawer is provided for article dispensing machines, especially those of the so-called "helix vendor" type, which is slideably removable from the front of the dispensing machine and includes at least one article receiving cartridge removably secured within the drawer for efficient loading, storage and release of articles to be dispensed therefrom. The cartridge is removable and replaceable after being loaded with articles from the front of the machine and does not require removal of the drawer for access thereto. An opening in the rear end of the cartridge permits rapid carton-like loading of articles therein when removed from the drawer for replenishment of the dispensing machine by a serviceman. A swingable, article engaging element mounted in the front of the drawer adjacent a pair of opposed lateral openings in the front end of the cartridge is actuated through a coupling forming a part of the drawer assembly by a power drive provided in the machine and operably coupleable with the drawer at the rear of the latter. When actuated, such element swings through one opposed opening in the cartridge adjacent its front extremity to contact an article and force the same through an opposed second opening, thereby dispensing the article.
