Abstract
Abstract A dispenser according to preferred teachings of the present invention is disclosed for use in a machine for vending generally cylindrical articles. The dispenser includes a generally cylindrical cradle rotatably mounted below the outlet of a storage enclosure. The enclosure is dimensioned to hold and store a plurality of articles in a serpentine column. The enclosure includes a guiding baffle for directing the bottom article into the outlet of the enclosure and an unweighting baffle which reduces the weight placed on the articles in the enclosure below the unweighting baffle and thus the weight transferred to the cradle by the article in the outlet. The cradle can then be rotated between a first position with an opening of a cavity formed in the cradle aligned with the outlet of the article storage enclosure for receiving an article from the enclosure and a second position with the cradle blocking the passage of articles through the outlet of the storage enclosure and with the opening of the cavity allowing the article to fall from the cavity through the opening. In its most preferred form, the cradle is formed as two generally equal semicylindrical halves which can be easily fabricated by injection molding and which are particularly adapted for interchanging for varying size articles to be vended.
