ABSTRACT:
A newspaper vendor has a spring-suspended elevator lifting a vertical stack of newspapers for presentation of successive papers at a vend position for withdrawal by a customer through a vend throat. A roller arrangement automatically aligns the uppermost newspaper with the throat regardless of non-uniform paper thickness. A door, when released, provides customer access to the throat. A door release mechanism is interconnected with a coin mechanism within the vendor to permit door opening upon insertion of coins totalling or exceeding the vend price. A vend control mechanism blocks customer withdrawal of a subsequent paper through the throat during each vend cycle in response to withdrawal of a first paper through the throat, including a latch, a latching mechanism biased for movement from a latched position to unlatched position when released by the latch, and a blocking member driven by release of the latching mechanism for movement within the throat for releasing the latch upon movement of the first paper through the throat, and linkage for relatching the latching mechanism upon closing the door. A throat adjustment mechanism allows quick change of the vertical dimension of the throat according to average newspaper thickness. The vend throat spacing is automatically made slightly greater than newspaper thickness. The coin mechanism allows operation to be changed for vending at either a daily or Sunday vend price.
