ABSTRACT:
A manually operated coil vending machine device is described which has a rod tipped with a pressure sensitive adhesive movable along a slot in the device to a storage bin area where articles for sale are stored and displayed. Once in the bin area, the rod is lowered until it sticks to the article selected, after which the rod is raised and moved back along the slot until it reaches an area accessible to the operator-purchaser. At such point, the purchased article is grasped and removed. The device can only be operated after predetermined coins equal to the purchase price of the articles have been inserted in the device, thereby permitting removal of a rod blocking first projection over the slot by pressure of the rod as it moves along the slot to the storage bin area. On its return to the accessible area, pressure of the rod against a rod blocking second projection over the slot removes the latter projection, and simultaneously returns the first projection to its blocking position over the slot, barring further entry to the storage bin area until additional coins have been inserted.
