ABSTRACT:
A vending machine of a type having a plurality of coin releasable and manually operable pull rods for selectively releasing a product to a consumer. A novel mechanism is provided for selectively locking or releasing the pull rods. This mechanism includes a rod pivotally attached to a frame, the rod being attached to a first lever which is, in turn, operably connected to the pull rod and to a second lever which is, in turn, pivotally attached to a third lever. Structure is provided for causing the third lever to be biased to a position wherein the pull rods are locked; but, upon the insertion of a predetermined amount of money into the vending machine, one of the pull rods can be actuated to release a product due to a changing of the fulcrum of the third lever and simultaneous movement of the third lever and its associated locking structure to thereby unlock one of the pull rods.
