Abstract: A vending machine includes a plurality of column walls that collectively define an associated plurality of stack areas for storing product containers. The column wall includes various, vertically spaced and fore-to-aft extending stiffeners embossed into the column wall. The integral stiffeners eliminate the need for any additional discrete stiffener parts and fasteners. In addition, the integral stiffeners advantageously permit thinner material to be employed in forming the column walls, thereby improving the entire manufacturing process. Preferably, one of the stiffeners constitutes a decoupling member which isolates a bottom portion of the column wall from a top portion and substantially prevents bow forces from transferring into a dispensing region of the column wall. Furthermore, each of the column walls is integrally formed with an alignment member or louver structure in the form of a guide element or flange which provides for proper product positioning through a vending area.

Abstract: A postage stamp booklet dispenser mechanism uses a multi-position gate cam, which rotates about a central axis and controls the opening and closing of opposed pairs of gate members through which the stamp booklets are dispensed. The operative followers of each pair of gates alternately move between dwell and rest positions to thereby provide corresponding open and closed modes of operation, resulting in the selective dispensing of single booklets from a criss-cross stack. By disposing one pair of gate members in a position slightly offset from the gate cam's central axis, one of the gate members of that pair receives a slight preferential opening position to insure that the booklet dispensed when that pair of gates is opened, falls in the proper orientation onto the chute of the dispenser mechanism. Between each dispensing cycle, all four gates return to their rest positions to prevent inadvertent dispensing and "jackpotting" of the entire stored group of booklets.
