  • Patent number: 4401235
    Abstract: The invention concerns a vending machine, e.g. of the coin-freed type, having a package-dispensing drawer (11) reciprocatable between a locked, retracted position and an open, extended dispensing position. The drawer length and the machine casing or frame are of sufficient depth to accommodate two vertical banks of packages one behind the other. The rear of the drawer (11) passes through and beyond an opening (14) in the rear wall (13) of the frame. Two upstanding slightly spaced-apart blocks (130,132) are secured to the drawer (11). The front block (130) supports the rear bank of packages and is of a height slightly less than that of the package. The two banks are separated by dividers the bottom edge of which is at a height less than twice the height of a package but more than the height of one package. The top surface (152) of the rear block (132) has projecting, freely rotatable rollers (150) to assist transfer of packages from the rear block to the front block (130).
