Abstract
Abstract A novel arrangement for using a standard totalizing coin mechanism in a newspaper vendor is disclosed. Instead of using a coin or stack of coins to depress a door latch as is now customary to permit access to a stack of papers, the present invention uses a pivotally mounted finger for this purpose. Whereas heretofore ratchet-like pawls have been used to restrict the upward motion of coins resulting in the depression of a door latch, the present invention uses a price cam affixed to a totalizer that in turn restricts the upward motion of the pivotally mounted finger to accomplish this function. Also disclosed are ways of resetting a totalizer and a dual price cam.
