Abstract
A multiple-product merchandising machine having a cylindrical drum mounted within a cabinet. The drum is divided into a plurality of horizontal shelves each of which is divided by a plurality of vertical walls into separate compartments from which the product can be dispensed. These compartments can be brought into alignment with access doors associated with each level and the doors, which are normally maintained locked, can be opened upon the insertion of adequate currancy in the machine to remove the product. The access door locking system prevents more than one door from being opened at one time. The drum is rotatable in either direction by a reversible motor. A viewing area is provided in the front of the machine which allows a prospective customer to see the product as it passes by. The drum is divided into sections with opaque walls which prevent viewing from the viewing area of more than half of the compartment on a shelf when the drum is in its rest position. The drum can be restricted in its rotation so that less than all of the compartments can be accessed by the access doors. The section which is accessable can be changed at different times of day, or if the previous section has had a lot of its items sold so that a new supply of items can be viewed and accessed.

Important Notes on Latency of Status data
Please note there is up to 60 days of latency in this Status indicator for certain status conditions. You can obtain up-to-date Status indicator readings by ordering PAIR for the file.
An application with the status "Published" (which means it is pending) may be recently abandoned, but not yet updated to reflect its abandoned status. However, an application filed less than one year ago is unlikely to be abandoned.
A patent with the status "Granted" may be recently expired, but not yet updated to reflect its expired status. However, it is highly unlikely a patent less than 3.5 years old would be expired.
An application with the status "Abandoned" is almost always current, but there is a small chance it was recently revived and the status not yet updated.
Important Note on Priority Date data
This priority date is an estimated earliest priority date and is purely an estimation. This date should not be taken as legal conclusion. No representations are made as to the accuracy of the date listed. Please consult a legal professional before relying on this date.
